(in the embodiment shown in fig. 4), the connecting plate 7 is a pair of connecting ear plates; the connecting ear plate is provided with an ear plate connecting hole; the lug plate connecting hole is in pin joint with the execution tail end of a piston rod of a transverse moving oil cylinder 10 through a round pin 9. The reversing device is simply and reliably connected with the piston rod of the transverse moving oil cylinder 10.

In the above embodiment, further: (as shown in fig. 3), the shaft body of the reversing shaft 2 is of a stepped shaft structure with a small upper part and a big lower part; the middle boss 203 of the step shaft structure is used for preventing the shaft body from completely falling out of the base body of the reversing seat 1 when the reversing shaft 2 is pulled up.

In the above embodiment, preferably: the first positioning hole 802 and the second positioning hole 803 are square holes. The square hole is adopted, the attaching area of the side of the clamping groove 201 of the reversing shaft 2 is larger than that of the round hole, and therefore the clamping limiting reliability of the reversing device in a limiting clamping state is higher.

It should be noted that: to facilitate the automatic withdrawal of the reversing shaft 2 from the first or second positioning hole (802/803) under the dragging force of the piston rod: when the reversing shaft 2 completely falls into the reversing seat 1, the upper end face of the axial vertical height of the large-upper-part and small-lower-part retreating inclined plane 202 formed on the reversing shaft 2 is higher than the upper end face of the hole edge of the first positioning hole or the second positioning hole (802, 803).

In the above embodiment, further: the bottom end surfaces of the outer sides of the first positioning hole 802 and the second positioning hole 803 of the 8-channel groove 801 of the rerailing beam are respectively provided with a thickened plate 11.

The center of the thickened plate 11 is provided with a thickened plate positioning hole; the positioning hole of the thickened plate has the same size as the first positioning hole 802 and the second positioning hole 803, and is fixedly connected with the first positioning hole and the second positioning hole in a vertical and opposite welding mode. Preferably: the first or second positioning holes (802, 803) and the thickened plate positioning holes are square holes, so that the assembling and bonding area of the reversing shaft 2 is increased when the first or second positioning holes (802, 803) and the thickened plate positioning holes are assembled, and the clamping and limiting reliability of the reversing device in a limiting and clamping state is improved.

The thickened plate 11 is used for increasing the axial thickness of the first positioning hole 802 and the second positioning hole 803 so as to firmly clamp the clamping groove 201 formed in the reversing shaft 2, and the firmness and the reliability of the limiting state of the reversing device are improved.

The working principle of the invention is as follows: during operation: when in use (as shown in the state of fig. 1): firstly, a connecting plate 7 of a reversing device is connected with a piston rod of a traversing oil cylinder 10 through a round pin 9, the reversing device is placed in a channel 801 of a rerailing beam 8, and a reversing shaft 2 falls into a first positioning hole 802 of a bottom plate of the rerailing beam 8. The reversing shaft receding slope 202 is arranged towards the right so as to be consistent with the direction of the rerailer running towards the right, and the clamping groove 201 is arranged towards the left: the piston rod of the traversing oil cylinder 10 extends towards the left side to push the left clamping groove 201 of the reversing shaft 2 to be clamped in the first positioning hole 802 of the rerailing beam 8, at the moment, the reversing device is not moved, the traversing oil cylinder 10 integrally moves towards the right side under the reverse acting force, and therefore the pushing rerailer moves towards the right side to enable the wheel pair to reset. When the reset distance is insufficient, the piston rod of the traversing oil cylinder 10 is retracted, the reversing device is pulled to move to the right side, the right side retreat inclined plane 202 of the reversing shaft 2 is adjacent to the right side of the first positioning hole 802, and then the inclined plane does not have a blocking effect, so the reversing shaft 2 is forced to retract upwards automatically until the reversing shaft 2 moves upwards and automatically retracts from the first positioning hole 802, the whole reversing device continues to move rightwards along with the piston rod retracted by the traversing oil cylinder 10, and at the moment, the oil cylinder is not moved until the reversing device is dragged along with the retracted piston rod to fall into the next second positioning hole 803 of the rerailing beam 8. After the reversing device is replaced to the second positioning hole 803, the piston rod of the traversing oil cylinder 10 extends towards the left side again, and the process is repeated, so that the reciprocating motion is used for prolonging the working stroke of the traversing oil cylinder.

When reversing manually: for example, after the reversing shaft 2 of the reversing device is changed to the second positioning hole 803, when manual reversing is needed: the reversing shaft 2 is manually lifted upwards, so that the limiting pin shaft 4 is withdrawn from the limiting groove 101, the reversing shaft 2 rotates 180 degrees, the right side retreat inclined plane 202 of the reversing shaft 2 in the state shown in fig. 1 is changed from the right side to the left side in fig. 1, and the clamping groove 201 side is changed from the left side to the right side. Namely, the manual reversing of the reversing shaft 2 is opposite to the working direction: when the piston rod of the transverse oil cylinder 10 retracts and moves towards the right side, the clamping groove 201 on the right side of the pushing reversing shaft 2 is clamped in the second positioning hole 803 of the rerailing beam, the reversing device is not moved, and the transverse oil cylinder 10 is used for pulling the rerailer to reset the wheel pair; when a piston rod of the transverse oil cylinder 10 extends towards the left side, the retreating inclined plane 202 on the left side of the reversing shaft 2 of the reversing device is attached to the left side wall of the second positioning hole 803, and the reversing shaft 2 is automatically retracted upwards under stress because the retreating inclined plane 202 has no limiting blocking function until the reversing shaft 2 moves upwards and automatically exits the second positioning hole 803; the reversing device retreats from the second positioning hole 803 along with the pushing of the piston rod extending towards the left side and moves towards the left side, and the traversing cylinder 10 is not moved until the reversing device falls into the first positioning hole 802 again. Therefore, the hydraulic rerailer can work in two directions by reciprocating.

From the above description it can be found that: when the reversing shaft 2 is pulled up manually, the manual reversing rotation of the reversing shaft 2 can be realized after the limiting pin shaft 4 is withdrawn from the concave limiting groove 101 formed at the top end of the reversing seat 1; when the reversing shaft 2 rotates to the clamping groove 201 to be clamped with the first or second positioning hole 802/803 of the rerailing beam 8, and the piston rod of the oil cylinder pushes the limiting block towards the clamping direction, the oil cylinder is used for limiting the movement of the reversing device, and only the oil cylinder moves; when the reversing shaft 2 rotates to the position-withdrawing inclined plane 202 to be attached to the first or second positioning hole 802/803 of the rerailing beam 8, the oil cylinder piston rod pulls the reversing device to move, the reversing shaft position-withdrawing inclined plane 202 is stressed to be automatically withdrawn upwards, and the reversing device moves forwards to an adjacent positioning hole.

The invention not only needs to manually operate the reversing shaft to rotate 180 degrees to carry out the switching operation of the side of the clamping groove 201 and the side of the retreating inclined plane 202 during reversing, but also does not need to manually contact a reversing device and a rerailer during the dragging work process of the oil cylinder, thereby ensuring the safety of personnel.

According to the invention, the hand wheel 3 is lifted, so that the reversing shaft 2 can move up and down in the vertical reversing shaft hole of the reversing seat 1; the reversing shaft 2 is lifted upwards, the limiting pin shaft 4 is rotated 180 degrees after being higher than the upper surface of the limiting groove 101 of the reversing seat 1 and then is loosened, and the reversing shaft 2 falls into the reversing seat 1 again to realize the reversing function; the structure is simple, the materials are easy to obtain, the manufacture is convenient, the assembly is convenient, and the manual reversing operation is simple and convenient.

The reversing seat 1 is provided with the guide plate 5, and the guide plate can play a role in linear guiding and positioning when sliding in the rerailing beam 8, so that the stability of the sliding operation of the reversing device is ensured.

One side of the guide plate 5 is provided with the connecting plate 7, and the connecting plate 7 is in pin joint with the oil cylinder, so that the connection is reliable, simple and convenient.

The bottom of the reversing device is provided with the bottom plate 6, sliding friction is formed between the bottom plate 6 and the rerailing beam 8, the friction resistance is small, and the sliding is rapid and convenient.

The reversing shaft 2 is a stepped shaft and cooperates with the small-diameter through hole 102 at the top end of the reversing seat 4, so that the problem that the reversing shaft 2 is accidentally pulled out during manual reversing operation can be effectively solved.

In conclusion, the hand wheel 3 is lifted, so that the reversing shaft 2 can move up and down in the vertical reversing shaft hole of the reversing seat 1, the reversing shaft 2 is lifted upwards, the limiting pin shaft 4 is rotated 180 degrees after being higher than the upper surface of the limiting groove 101 of the reversing seat 1, and the reversing shaft 2 falls into the reversing seat 1 again, thereby realizing the reversing function. The manual reversing device can prolong the working stroke of the transverse moving oil cylinder of the hydraulic rerailer; through manual reversing, the hydraulic rerailer can work reversely, and bidirectional work of the hydraulic rerailer is realized. The device adopts manual control, is simple and easy to implement, has lower cost and small structure, and can bear larger shearing force; easy operation, economy and practicality.
