In the initial state of the invention, the trigger plate 31 and the trigger block 57 are in a separated state, at this time, the adjusting cylinder 40 is positioned at one side far away from the installation slide block 6, and one end of the trigger slide plate 18 with the mark does not penetrate out of the outer side of the installation slide block 6; when a cable is wound, the rocker 28 is pulled to rotate the second mounting sleeve 27, and the second mounting sleeve 27 drives the pay-off roller to rotate through the matching of the transmission key 55 and the key groove so as to wind the cable; in the rotation process of the second mounting sleeve 27, after the trigger block 57 on the second mounting sleeve 27 is contacted with the trigger plate 31 and the trigger sliding plate 18, the trigger sliding plate 18 and the trigger sliding plate 31 are extruded under the action of the fourth inclined surface 58 on the trigger block 57, the adjusting cylinder 40 moves to one side close to the mounting sliding block 6, and one end of the trigger sliding plate 18 with the mark extends out of the mounting sliding block 6; when the rotation process is continued, after the trigger plate 31 and the trigger sliding plate 18 are separated from the trigger block 57, the trigger sliding plate 18 is reset and moved back under the action of the fourth spring 59; the trigger plate 31 drives the transmission mounting block 26 to slide towards the side far away from the mounting slide block 6 under the action of the fifth spring 61 in the telescopic rod 33, but the sliding speed of the transmission mounting block 26 is relatively low due to the existence of the damping rod 34, before the transmission mounting block 26 does not slide to enable the limiting block 32 to be separated from the adjusting cylinder 40, the trigger plate 31 and the trigger slide plate 18 will contact with the next trigger block 57 and be squeezed again under the action of the fourth inclined surface 58 on the trigger block 57, the adjusting cylinder 40 moves to the side near the mounting slide block 6, and the end, with the mark, of the trigger slide plate 18 extends out of the mounting slide block 6; in the process, the limiting block 32 always limits the adjusting cylinder 40, namely, the outer end of the volute spiral spring 49 is always limited and clamped; after the cable winding is completed, the trigger sliding plate 18 and the trigger plate 31 are restored to the initial state, the trigger plate 31 and the trigger block 57 are in a separated state, the adjusting cylinder 40 is located at the side far away from the installation sliding block 6, and the end of the trigger sliding plate 18 with the mark does not penetrate out of the installation sliding block 6.

In the process of winding the cable, the transmission block 29 presses the telescopic slide rod 62 through the second inclined surface 39 on the telescopic slide rod 62; in the initial state, the telescopic slide rod 62 is matched with the straight surface of the transmission block 29, when a cable is wound, the transmission mounting block 26 is firstly extruded by the trigger block 57 to be far away from the transmission block 29, so that the matching area of the telescopic slide rod 62 and the straight surface of the transmission block 29 is staggered, and the second inclined surface 39 on the telescopic slide rod 62 is matched with the transmission block 29.

When the cable needs to be taken down, the second mounting sleeve 27 is shaken through the rocker 28, and the limiting block 32 loses the limiting effect on the adjusting cylinder 40 at the moment; when the auxiliary mechanism 3 is seen from the direction of the rocker 28, because the first mounting sleeve 19 mounted at the inner end of the spiral spring 49 is limited by the limiting fixture block 45, and the limiting block 32 limiting the outer end of the spiral spring 49 loses the limiting, the outer end of the spiral spring 49 is released at the moment, and the outer end of the spiral spring 49 releases to apply a clockwise rotation driving force to the second mounting sleeve 27 mounted with the spiral spring; in this process, since the telescopic sliding rod 62 is vertically engaged with the driving block 29, in this state, the rotational force applied to the second mounting sleeve 27 by the outer end of the spiral spring 49 is transmitted to the second mounting sleeve 27 through the engagement of the driving mounting block 26 and the driving block 29, and the second mounting sleeve 27 transmits the rotational force to the mounting shaft 5, thereby providing a certain auxiliary effect on the rotation start of the winding roller 1.

As shown in fig. 2 and 14, one end of the mounting shaft 5 is fitted to the mounting slider 6 of the non-mounting assist mechanism 3 by a key and a key groove, and the other end of the mounting shaft 5 is fitted to the second mounting sleeve 27 by a key and a key groove.

As shown in fig. 4, two guide sliding rods 16 are symmetrically installed on the lower sides of the two installation sliders 6, and the four guide sliding rods 16 are nested inside the four first springs 17 in a one-to-one correspondence manner. The guide slide 16 prevents the first spring 17 from buckling under pressure.

As shown in fig. 7, a seventh gear 20 is fixedly mounted at one end of the first mounting sleeve 19, and the seventh gear 20 is located inside the bracket 2; the transmission 22 is fixedly arranged on the corresponding side bracket 542 through the fixed support 24, the output shaft of the transmission 22 is fixedly provided with a fifth gear 21, and the fifth gear 21 is meshed with the seventh gear 20; the sixth gear 23 is fixedly mounted on the input shaft of the transmission 22, the fixed rack 25 is fixedly mounted on the corresponding side bracket 542, and the fixed rack 25 meshes with the sixth gear 23.

When the mounting sliding block 6 slides downwards, the seventh gear 20 drives the first mounting sleeve 19 to rotate anticlockwise through the speed changing direction of the speed changer 22, and the winding roller 1 rotates clockwise to wind the cable when viewed from the direction of the rocker 28.

As shown in fig. 2, a rocker 28 is fixedly mounted on one end of the second mounting sleeve 27 located outside the bracket 2. The winding or the paying-off can be conveniently and manually carried out.

In the invention, the adjusting cylinder 40 returns to one side close to the mounting slide block 6 after sliding once around the guide rail 41, the spiral spring 49 applies a starting auxiliary force to the winding roller 1 once in the process, and the winding roller 1 correspondingly pays off once; after the adjusting cylinder 40 has been slid into the track on the side close to the mounting slide 6 via the transition area 44 on the guide rail 41, it is then returned by the fifth spring 61 and moved to the side remote from the mounting slide 6.

According to the invention, whether the trigger plate 31 is matched with the trigger block 57 can be determined by the state that the trigger sliding plate 18 extends out of one end of the mounting slide block 6, namely whether the equipment is in an initial state; when the trigger slide plate 18 extends out of the mounting slide block 6, the trigger plate 31 is located on the trigger block 57, and the outer end of the spiral spring 49 is limited and cannot play an auxiliary role.

The specific working process is as follows: when the support frame designed by the invention is used, firstly, the winding roller 1 is lifted and moved to the middle of the support frame 2 through auxiliary equipment, then the mounting shaft 5 is inserted into the side which is not provided with the auxiliary mechanism 3, so that the transmission key 55 on the mounting shaft 5 is matched with the mounting sliding block 6 which is not provided with the auxiliary mechanism 3 through a key and a key slot, then the mounting shaft 5 passes through the winding roller 1 and is finally inserted into the second mounting sleeve 27, so that the mounting shaft 5 is matched with the second mounting sleeve 27 through a key and a key slot; the mounting shaft 5 is matched with the winding roller 1 through a key and a key groove; in this state, the two mounting sliders 6 are positioned on the upper sides of the two side brackets 542 by the first spring 17; the adjusting cylinder 40 installed on the transmission installation block 26 is matched with the track on the side, far away from the installation sliding block 6, of the guide rail 41 but does not slide in, and the limiting block 32 does not limit the sliding of the adjusting cylinder 40 towards the track on the side, far away from the installation sliding block 6, of the guide rail 41.

Then, the rocker 28 drives the second mounting sleeve 27 to rotate, and the second mounting sleeve 27 drives the pay-off roller to rotate anticlockwise through the matching of the transmission key 55 and the key groove so as to wind wires; in the rotation process of the second mounting sleeve 27, after the trigger block 57 on the second mounting sleeve 27 is contacted with the trigger plate 31 and the trigger sliding plate 18, the trigger sliding plate 18 and the trigger sliding plate 31 are extruded under the action of the fourth inclined surface 58 on the trigger block 57, the adjusting cylinder 40 moves to one side close to the mounting sliding block 6, and one end of the trigger sliding plate 18 with the mark extends out of the mounting sliding block 6; when the rotation process is continued, after the trigger plate 31 and the trigger sliding plate 18 are separated from the trigger block 57, the trigger sliding plate 18 is reset and moved back under the action of the fourth spring 59; the trigger plate 31 drives the transmission mounting block 26 to slide towards the side far away from the mounting slide block 6 under the action of the fifth spring 61 in the telescopic rod 33, but the sliding speed of the transmission mounting block 26 is relatively low due to the existence of the damping rod 34, before the transmission mounting block 26 does not slide to enable the limiting block 32 to be separated from the adjusting cylinder 40, the trigger plate 31 and the trigger slide plate 18 will contact with the next trigger block 57 and be squeezed again under the action of the fourth inclined surface 58 on the trigger block 57, the adjusting cylinder 40 moves to the side near the mounting slide block 6, and the end, with the mark, of the trigger slide plate 18 extends out of the mounting slide block 6; in the process, the limiting block 32 always limits the adjusting cylinder 40, namely, the outer end of the volute spiral spring 49 is always limited and clamped; during the winding process, the winding roller 1 is heavier along with the increase of the cable on the winding roller 1, and drives the two mounting sliders 6 to move downwards, when the two mounting sliders 6 move downwards, the mounting slider 6 of the mounting auxiliary mechanism 3 drives the first mounting sleeve 19, the speed changer 22, the seventh gear 20, the fifth gear 21 and the sixth gear 23 mounted thereon to slide downwards relative to the corresponding side bracket 542, when the sixth gear 23 moves downwards relative to the corresponding side bracket 542, the sixth gear 23 rotates under the action of the fixed rack 25 fixedly mounted on the side bracket 542, the sixth gear 23 rotates to drive the input shaft of the speed changer 22 to rotate, the input shaft of the speed changer 22 rotates to drive the output shaft of the speed changer 22 to rotate after being shifted by the speed changer 22, the output shaft of the speed changer 22 rotates to drive the fifth gear 21 to rotate, the fifth gear 21 rotates to drive the seventh gear 20 to rotate, the seventh gear 20 rotates to drive the first mounting sleeve 19 to rotate, the inner end of the spiral spring 49 rotates clockwise, and the spiral spring 49 stores power.

After winding is finished, the triggering block 57, the triggering plate 31 and the triggering sliding plate 18 are distributed in a staggered mode, and the triggering sliding plate 18 can reset and move back under the action of the fourth spring 59; the trigger plate 31 drives the transmission mounting block 26 to slowly slide and reset towards the side far away from the mounting slide block 6 under the action of the fifth spring 61 and the damping rod 34 in the telescopic rod 33, so that the limiting block 32 is not limited to the rail sliding of the adjusting cylinder 40 towards the side, far away from the mounting slide block 6, on the guide rail 41.

When the cable needs to be paid off, the cable is pulled manually, and the limiting block 32 loses the limiting effect on the adjusting cylinder 40; when the auxiliary mechanism 3 is seen from the direction of the rocker 28, because the first mounting sleeve 19 mounted at the inner end of the spiral spring 49 is limited by the limiting fixture block 45, and the limiting block 32 limiting the outer end of the spiral spring 49 loses the limiting, the outer end of the spiral spring 49 is released at the moment, and the outer end of the spiral spring 49 releases to apply a clockwise rotation driving force to the second mounting sleeve 27 mounted with the spiral spring; in the process, because the telescopic slide rod 62 is vertically matched with the transmission block 29, in this state, the rotating force applied to the second mounting sleeve 27 by the outer end of the spiral spring 49 is released, and is transmitted to the second mounting sleeve 27 through the matching of the transmission mounting block 26 and the transmission block 29, and the second mounting sleeve 27 transmits the rotating force to the mounting shaft 5, so that a certain auxiliary effect is provided for the clockwise rotation starting of the winding roller 1; at this time, the transmission mounting block 26 transmits the driving force to the second mounting sleeve 27 through the telescopic sliding rod 62 and the transmission block 29, the second mounting sleeve 27 is transmitted to the mounting shaft 5, the mounting shaft 5 is transmitted to the winding roller 1, and the telescopic sliding rod 62 is stationary relative to the second mounting sleeve 27; after the adjusting cylinder 40 slides once around the guide rail 41, the adjusting cylinder returns to the side close to the mounting slide block 6 again under the action of the guide rail 41, the transmission mounting block 26 is limited by the limiting block 32, and the transmission block 29 is disengaged from the telescopic slide rod 62; the second mounting sleeve 27 can drive the trigger block 57 to continue rotating along with the winding roller 1, and in the process of continuing rotating the winding roller 1, the trigger sliding plate 18 can reset and move back under the action of the fourth spring 59; the trigger plate 31 drives the transmission mounting block 26 to slide towards the side far away from the mounting slide block 6 under the action of the fifth spring 61 in the telescopic rod 33, but the sliding speed of the transmission mounting block 26 is relatively low due to the existence of the damping rod 34, before the transmission mounting block 26 does not slide to enable the limiting block 32 to be separated from the adjusting cylinder 40, the trigger plate 31 and the trigger slide plate 18 will contact with the next trigger block 57 and be squeezed again under the action of the fourth inclined surface 58 on the trigger block 57, the adjusting cylinder 40 moves to the side near the mounting slide block 6, and the end, with the mark, of the trigger slide plate 18 extends out of the mounting slide block 6; that is, in this process, the limiting block 32 always limits the adjusting cylinder 40, that is, the outer end of the spiral spring 49 is always blocked by the limiting block, and the auxiliary driving force is not continuously applied until the winding roller 1 stops.

When the winding roller 1 stops, the trigger block 57, the trigger plate 31 and the trigger sliding plate 18 are distributed in a staggered manner, and the trigger sliding plate 18 is reset and moves back under the action of the fourth spring 59; the trigger plate 31 drives the transmission mounting block 26 to slowly slide and reset towards the side far away from the mounting slide block 6 under the action of the fifth spring 61 and the damping rod 34 in the telescopic rod 33, so that the limiting block 32 is not limited to the rail sliding of the adjusting cylinder 40 towards the side, far away from the mounting slide block 6, on the guide rail 41. In this state, the cable is ready to be pulled out next time.

The spiral spring 49 applies a starting assisting force to the wind-up roller 1 once and once for every time the cable is pulled out, which facilitates the starting.
