The system is suitable for the three-section arm frame, one end of the drag chain is fixed on the first section arm of the platform, the other end of the drag chain is connected with the third section arm of the platform through a square pipe, the whole drag chain is arranged in a sliding groove connected with the second section arm of the platform, the sliding groove and the drag chain extend out simultaneously along with the extension of the arm frame, but the extending speed of the drag chain is one time faster than that of the sliding groove, so that relative motion can be generated on the sliding groove, namely the drag chain can gradually move from a lower layer groove of the sliding groove to an upper layer groove of the.

One end of the platform third knuckle arm 8 is arranged in the platform second knuckle arm 7 and can freely slide along the inner wall of the platform second knuckle arm 7, and one end of the platform second knuckle arm 7 is arranged in the platform first knuckle arm 6 and can freely slide along the inner wall of the platform first knuckle arm 6.

The other end of the third arm section 8 of the platform is fixed with a square tube fixing frame 10, and the other end of the square tube 1 is fixed on the square tube fixing frame 10. The other end of the second section arm 7 of the platform is fixed with a chute fixing bracket 11, and the chute 4 on the upper layer of the chute 2 and the chute fixing bracket 11 on the other end of the chute 5 on the lower layer are fixed. One end of the drag chain 3 is fixed at the end of the platform first knuckle arm 6 through a drag chain fixing bracket 12.

One end parts of the upper layer sliding groove 4 and the lower layer sliding groove 5 are in transition communication through a circular arc-shaped end part shell 13, the shape of the circular arc-shaped end part shell 13 is matched with the upper layer and lower layer bending shapes of the drag chain 3, a supporting wheel 14, a limiting wheel 15 and a supporting block 16 are arranged in the circular arc-shaped end part shell 13, two ends of the supporting wheel 14 are rotatably arranged on two sides of the circular arc-shaped end part shell 13, the supporting block 16 is a wedge-shaped block and the supporting block 16 is fixed in the sliding groove 2, two ends of the limiting wheel 15 are rotatably arranged on the side walls of two sides of the sliding groove 2, and the distance between.

One end part of the sliding chute 2 is arranged on the first section arm 6 of the platform in a sliding way through a sliding mechanism. The sliding mechanism comprises a pulley 17, a sliding rod 18 and a sliding rod support 19, wherein the pulley 17 is rotatably arranged at the lower side of one end part of the sliding chute 2, the sliding rod 18 is arranged along the length direction of the first section arm 6 of the platform and is fixed on the side surface of the first section arm 6 of the platform through the sliding rod support 19, and the pulley 17 is arranged at the upper end of the sliding rod 18 and can move back and forth along the sliding rod 18 in the horizontal direction.

The working principle of the invention is as follows: when the first section of arm 6 of platform is fixed, when platform second section arm 7 and platform third section arm 8 stretch out simultaneously, platform second section arm 7 and platform third section arm 8 take spout 2 and square pipe 1 motion respectively, and square pipe 1 can take the tow chain 3 of being connected with it to move together simultaneously. And the other end of the drag chain 3 is connected with the first section arm 6 of the platform through the drag chain fixing support 12, and is in the upper and lower two-layer groove of the sliding groove 2, because the moving speed of the third section arm 8 of the platform is twice of that of the second section arm 7 of the platform, therefore along with the gradual extension of the second section arm 7 of the platform and the third section arm 8 of the platform, the drag chain 3 can generate relative motion to the sliding groove, gradually transit motion from the sliding groove 5 of the lower layer to the sliding groove 4 of the upper layer through the supporting wheel 14, and meanwhile, the motion trail of the drag chain is normalized and limited by the limiting wheel 16 (the position of which can be. When the arm support stretches out in place, the drag chain 3 and the electric and hydraulic pipelines in the drag chain synchronously stretch out in place. And similarly, when the second section arm 7 of the platform and the third section arm 8 of the platform retract simultaneously, the sliding chute 2 and the square pipe 1 retract synchronously, the drag chain 3 and the electric and hydraulic pipelines therein move to the sliding chute 5 at the lower layer from the sliding chute 4 at the upper layer step by step, and when the second section arm 7 of the platform and the third section arm 8 of the platform retract to the right position, the drag chain 3 and the electric and hydraulic pipelines therein retract to the right position synchronously, thereby completing one motion cycle of the drag chain system.

The whole drag chain is wrapped in the sliding groove, so that the drag chain, the electric pipeline and the hydraulic pipeline move in the sliding groove and are separated from the external environment, and a good protection effect is achieved. In addition, a V-shaped sliding rod is arranged on the first section arm, a V-shaped pulley is arranged at the bottom of the whole drag chain system, and the whole drag chain system moves back and forth on the sliding rod through the pulley. Because the spout can have the supporting role to the tow chain all the time, consequently do not have the requirement to the rigidity of tow chain to make things convenient for tow chain selection reduce cost.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
