[0034] In the above embodiment, further: (such as Figure 2 The structure shown in FIG. 1 is a simplified structure: the reversing seat 1 is a vertical sleeve structure with the opening facing downward.

[0035] A small diameter through hole 102 is formed at the center of the upper end of the reversing seat 1 of the sleeve structure; the small diameter through hole 102 is coaxially spaced and plugged with the reversing shaft 2. It is used to provide vertical guidance for the pulling and lifting of the reversing shaft 2.

[0036] The lower end of the sleeve structure of the reversing seat 1 is a large diameter through hole 103 that passes through from top to bottom. The large diameter through hole 103 is used for welding and fixing the horizontal seat plate 6 described later.

[0037] In the above embodiment, further: the front and rear axisymmetric edges of the top of the reversing seat 1 are respectively provided with the front and rear axisymmetric limiting grooves 101 with the front and rear center lines being collinear and downwardly concave. From a literal understanding, any groove type that can achieve the limiting function is applicable to this case.

[0038] In the specific implementation, preferably: the limiting groove 101 is a square groove with an inner concave structure. For the specific structure of the square groove, see Figure 2 , Figure 4 shown.

[0039] The limit pin 4 is vertically fixed to the reversing shaft 2 ; the limit pin 4 limits the rotation of the reversing shaft 2 by being inserted into the limit groove 101 ; the limit pin 4 is used to realize the rotation of the reversing shaft 2 after exiting the limit groove 101 .

[0040] The reversing shaft 2 which can rotate and rise and fall is installed in the vertical reversing shaft hole of the reversing seat 1 (i.e. the small diameter through hole 102 and the large diameter through hole 103 in the center of the reversing seat 1 described above). Preferably, the reversing shaft 2 and the small diameter through hole 102 are gap-matched.

[0041] The middle part of the reversing shaft 2 is perpendicular to the vertical axis and is fixedly installed with a limit pin 4 (such as Figure 4 The structure is simple, the production is convenient, and the limit stop is reliable.

[0042] The limit pin 4 is gap-matched with the limit slot 101 , and can be inserted into or pulled out upward from the reversing shaft 2 so that the limit pin 4 exits the limit slot 101 .

[0043] When in use: the limit pin 4 is inserted into the limit groove 101 and the limit block of the reversing seat 1 to limit the rotation of the reversing shaft 2; after the reversing shaft 2 is pulled upward and withdrawn from the limit groove 101 of the reversing seat 1, the reversing shaft 2 is manually rotated for reversing.

[0044] (like Figure 3 As shown in the figure, the left and right axial symmetric sides of the reversing shaft 2 passing through the bottom of the reversing seat 1 are provided with a slot 201 on the left side and a retreat slope 202 on the right side. From the literal meaning, any slot 201 structure that can achieve a snap connection is applicable to this case. Any slope structure that can achieve a retreat function is applicable to this case.

[0045] In specific implementation, preferably: the card slot 201 is a right-angle card slot. The right-angle card slot has the advantages of simple structure and reliable card connection.

[0046] In the above embodiment, further: the outer side of the reversing seat 1 is welded and fixedly connected with the guide plate 5. Any guide plate 5 structure that can realize the guiding structure is applicable to this case.

[0047] In specific implementation, preferably: the structure of the guide plate 5 is combined with Figure 2 See also Figure 4 The guide plate 5 is horizontally arranged and slidingly and frictionally adapted to the inner wall of the horizontal groove 801 of the rerailing beam 8 to provide a linear guide for the sliding lateral movement of the reversing seat 1 along the groove 801.

[0048] In the above embodiment, further: the bottom of the reversing seat 1 is provided with a horizontal seat plate 6 for increasing the bottom area of ​​the reversing device, thereby improving the support stability of the reversing device during horizontal sliding. In specific implementation, preferably: the horizontal seat plate 6 is made of a horizontal steel plate with a central hole.

[0049] The lower bottom surface of the horizontal seat plate 6 is slidingly and frictionally matched with the inner side wall of the lower bottom surface of the groove 801 of the re-tracking beam 8, and the sliding friction contact surface is a polished contact surface to reduce the sliding friction resistance. Convenient and efficient sliding displacement. In specific implementation, preferably: the central through hole 601 of the horizontal seat plate 6 is equal to the large diameter through hole 103 at the bottom end of the seat body of the reversing seat 1, and the upper and lower coaxial welding is fixedly connected as a whole. Convenient processing, easy to implement, simple structure, reliable connection.

[0050] In the above embodiment, further: for the convenience of manual operation: the top end of the reversing shaft 2 is coaxially fixedly connected to facilitate the insertion and removal of a handle member for lifting the reversing shaft 2 in the vertical reversing shaft hole of the reversing seat 1. From a literal understanding, any handle structure that can realize handheld operation is applicable to this case.

[0051] In the above embodiment, preferably: the handle is a hand wheel 3; the material is readily available and easy to implement. The hand wheel 3 is coaxially fixedly connected with the shaft body of the reversing shaft 2 through a thread, which has a simple structure and is easy to assemble. The reversing shaft 2 is lifted by pulling the hand wheel 3.

[0052] In the above embodiment, further: in order to adopt a simple and reliable connection structure to realize the connection between the reversing device and the transverse cylinder 10: a connecting plate 7 is provided at the outer end of the guide plate 5.

[0053] (like Figure 4 In the embodiment shown in the figure, the connecting plate 7 is a pair of connecting ear plates; the connecting ear plates are provided with ear plate connecting holes; the ear plate connecting holes are connected to the piston rod actuating end of the traverse oil cylinder 10 through round pins 9, so as to realize a simple and reliable connection between the reversing device and the piston rod of the traverse oil cylinder 10.

[0054] In the above embodiment, further: (such as Figure 3As shown in the figure, the shaft body of the reversing shaft 2 is a stepped shaft structure with a small top and a large bottom; the middle boss 203 of the stepped shaft structure is used to prevent the shaft body from completely falling out of the reversing seat 1 when the reversing shaft 2 is pulled up. Specifically, the middle boss 203 is blocked by the small diameter through hole 102 formed at the center of the top of the reversing seat 1 to prevent the reversing shaft 2 from completely falling out when it is pulled up, thereby reducing the difficulty of operation.

[0055] In the above embodiment, further: (such as Figure 1 When the slot 201 side of the reversing shaft 2 is engaged with the first and second positioning holes (802, 803), it is used to limit the movement of the reversing device; when the reversing shaft 2 is rotated to the point where its retreat slope 202 side is in contact with the first and second positioning holes (802, 803), when the piston rod of the transverse oil cylinder drags the reversing device, the retreat slope 202 of the reversing shaft 2 will cause the reversing shaft 2 to automatically move upward under the dragging force, and automatically withdraw from the first and second positioning holes (802, 803), thereby realizing the synchronous dragging and transverse movement of the reversing device with the piston rod.

[0056] In the above embodiment, preferably: the first positioning hole 802 and the second positioning hole 803 are square holes. The square holes have a larger contact area with the slot 201 side of the reversing shaft 2 than the round holes, so the reliability of the clamping and limiting of the reversing device in the limited clamping state is higher.

[0057] It should be noted that: in order 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 retreat inclined surface 202 with a larger upper portion and a smaller lower portion formed on the reversing shaft 2 is higher than the upper end face of the hole edge of the first or second positioning hole (802, 803).

[0058] In the above embodiment, further: the lower bottom end surfaces of the outer sides of the first positioning hole 802 and the second positioning hole 803 of the groove 801 of the rerailing beam 8 are respectively provided with thickened plates 11 .

[0059] The thickened plate 11 is provided with a thickened plate positioning hole in the center; the size of the thickened plate positioning hole is equal to that of the first positioning hole 802 and the second positioning hole 803, and the thickened plate positioning hole is vertically opposite to each other and welded and fixedly connected as a whole. Preferably, the first or second positioning hole (802, 803) and the thickened plate positioning hole are both square holes, so as to increase the fitting area when the reversing shaft 2 is mounted against the first or second positioning hole (802, 803) and the thickened plate positioning hole, thereby improving the reliability of the clamping and limiting state of the reversing device.

[0060] The thickened plate 11 is used to increase the axial thickness of the first positioning hole 802 and the second positioning hole 803 so as to firmly engage the slot 201 formed on the reversing shaft 2 and improve the firmness and reliability of the limiting state of the reversing device.

[0061] The working principle of the present invention is: during operation: (such as Figure 1 When in use: first connect the connecting plate 7 of the reversing device to the piston rod of the transverse oil cylinder 10 through the round pin 9, put the reversing device into the groove 801 of the rerailing beam 8, and the reversing shaft 2 falls into the first positioning hole 802 of the bottom plate of the rerailing beam 8. The reversing shaft retreat slope 202 is set to the right to be consistent with the direction of the rerailer running to the right, and the slot 201 is set to the left: the piston rod of the transverse oil cylinder 10 extends to the left to push the left slot 201 of the reversing shaft 2 to be stuck in the first positioning hole 802 of the rerailing beam 8. At this time, the reversing device does not move, and the transverse oil cylinder 10 moves to the right as a whole under the reverse force, thereby pushing the rerailer to move to the right to reset the wheelset. When the reset distance is not enough, the piston rod of the traverse oil cylinder 10 is retracted, pulling the reversing device to move to the right. After the right retreat slope 202 of the reversing shaft 2 abuts the right side of the first positioning hole 802, the slope does not have a blocking effect, so the reversing shaft 2 is automatically retracted upward by force until the reversing shaft 2 moves upward and automatically exits the first positioning hole 802. The reversing device as a whole continues to move to the right with the retracted piston rod of the traverse oil cylinder 10. At this time, the oil cylinder does not move until the reversing device is dragged by the retracted piston rod and falls into the next second positioning hole 803 of the rerail beam 8. After the reversing device is switched to the second positioning hole 803, the piston rod of the traverse oil cylinder 10 extends to the left again, repeating the above process, and this reciprocating process is used to extend the working stroke of the traverse oil cylinder.

[0062] When manual reversing is performed: for example, after the reversing shaft 2 of the reversing device is moved to the second positioning hole 803, when manual reversing is required: the reversing shaft 2 is manually lifted upward to make the limiting pin 4 exit the limiting groove 101, and the reversing shaft 2 is rotated 180° so that the reversing shaft 2 is as shown in FIG. Figure 1 The right side retreat slope 202 in the shown state is Figure 1 The right side is switched to the left side, and the slot 201 side is switched from the left side to the right side. That is, after the manual reversal of the reversing shaft 2, it is opposite to the aforementioned working direction: when the piston rod of the transverse oil cylinder 10 is retracted and moved toward the right side, the slot 201 on the right side of the reversing shaft 2 is pushed and stuck in the second positioning hole 803 of the rerailing beam, the reversing device does not move, and the transverse oil cylinder 10 is used to pull the rerailing device to reset the wheelset; when the piston rod of the transverse oil cylinder 10 is extended to the left side, the retreat slope 202 on the left side of the reversing shaft 2 of the reversing device is made to fit the left side wall of the second positioning hole 803. Since the retreat slope 202 has no unlimited blocking effect, the reversing shaft 2 is automatically retracted upward by force until the reversing shaft 2 moves upward and automatically exits the second positioning hole 803; the reversing device moves toward the left side after exiting the second positioning hole 803 as pushed by the piston rod extending toward the left side, and the transverse oil cylinder 10 does not move until the reversing device falls into the first positioning hole 802 again. In this reciprocating manner, the hydraulic rerailing device can work in both directions.

[0063] Through the above description, it can be found that: when the reversing shaft 2 of the present invention is manually pulled up, the limit pin shaft 4 exits the concave limit groove 101 formed on the top of the reversing seat 1, and the manual reversing rotation of the reversing shaft 2 can be realized; when the reversing shaft 2 is rotated to the clamping groove 201 and is engaged with the first or second positioning hole 802 / 803 of the rerailing beam 8, the cylinder piston rod pushes the limit block in the clamping direction, which is used to limit the movement of the reversing device, and only the cylinder moves; when the reversing shaft 2 is rotated to the retreat slope 202 and is in contact with the first or second positioning hole 802 / 803 of the rerailing beam 8, the cylinder piston rod pulls the reversing device to move, and the reversing shaft retreat slope 202 is automatically retracted upward under force, and the reversing device moves forward to the adjacent positioning hole.

[0064] In the present invention, except that the reversing shaft needs to be manually rotated 180 degrees to perform the switching operation between the slot 201 side and the retreat slope 202 side during reversing, there is no need for human contact with the reversing device and the rerailer during the oil cylinder dragging operation, thereby ensuring personnel safety.

[0065] The present invention can make the reversing shaft 2 move up and down in the vertical reversing shaft hole of the reversing seat 1 by lifting the hand wheel 3; the reversing shaft 2 is lifted up, so that the limit pin shaft 4 is higher than the upper surface of the limit groove 101 of the reversing seat 1, and then rotated 180° and released, 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 production is convenient, the assembly is convenient, and the manual reversing operation is simple and convenient.

[0066] The reversing seat 1 of the present invention is provided with a guide plate 5, which can play a role of linear guiding and positioning when sliding in the rerailing beam 8, thereby ensuring the stability of the sliding operation of the reversing device.

[0067] A connecting plate 7 is provided on one side of the guide plate 5 of the present invention, and the connecting plate 7 is pin-connected with the oil cylinder, so that the connection is reliable, simple and convenient.

[0068] A bottom plate 6 is provided at the bottom of the reversing device of the present invention, and there is sliding friction between the bottom plate 6 and the rerailing beam 8, so the friction resistance is small and the sliding is fast and convenient.

[0069] The reversing shaft 2 of the present invention is a stepped shaft, which cooperates with the small-diameter through hole 102 at the top of the reversing seat 4 to effectively prevent the reversing shaft 2 from being accidentally pulled out during manual reversing operation.

[0070] In summary, the present invention can make the reversing shaft 2 move up and down in the vertical reversing shaft hole of the reversing seat 1 by lifting the hand wheel 3. The reversing shaft 2 is lifted upward, so that the limit pin 4 is higher than the upper surface of the limit groove 101 of the reversing seat 1 and then rotated 180°, and the reversing shaft 2 falls back into the reversing seat 1 to achieve the reversing function. The manual reversing device can extend the working stroke of the hydraulic rerailer transverse cylinder; through manual reversing, the hydraulic rerailer can work in reverse to achieve bidirectional operation of the hydraulic rerailer. The device adopts manual control, which is simple and easy, low in cost, compact in structure, and can withstand large shear force; it is easy to operate and economical and practical.
