Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] The core of the present application is to provide a rubber pad pre-assembly device suitable for new sleepers, which realizes pre-installation of new sleeper pads, automatic removal and recycling of positioning pieces, and high efficiency of replacing sleepers. Another core of the present application is to provide a sleeper replacement method applied to the above-mentioned rubber pad pre-assembly device suitable for new sleepers.

[0047] Please refer to Figures 1 to 4 The present application provides a rubber pad pre-assembly device suitable for new sleepers, which includes an auxiliary assembly, a walking assembly 5 and a recycling assembly 6.

[0048] The auxiliary assembly includes at least two positioning pieces 41, the positioning piece 41 has a connecting portion 411 and a pressing portion 412, the connecting portion 411 is used for detachably connecting the positioning piece 41 to the sleeper 1, and the pressing portion 412 is located at the bottom of the connecting portion 411 and is used for pressing the rubber pad 3 at a preset position on the top of the sleeper 1; the walking assembly 5 can travel along the railway track; the recycling assembly 6 is arranged on the top of the walking assembly 5 and includes a power piece, an execution piece 62 and a material collecting piece 63, the power piece is connected to the execution piece 62 to drive the execution piece 62, and the execution piece 62 is used for detaching the positioning piece 41 and sending the positioning piece 41 into the material collecting piece 63.

[0049] The positioning member 41 is used for detachable connection with the sleeper 1. Optionally, the positioning member 41 is in a stepped columnar structure, and an outer thread is formed on the peripheral surface of the smaller-diameter end of the positioning member 41. In use, the rubber pad 3 is placed at the preset position on the top of the sleeper 1, and the positioning member 41 is screwed into the hole for setting the spike 11 in the sleeper 1, and the other end of the positioning member 41 with larger diameter abuts against the rubber pad 3 placed above. After the rail 2 is placed on the rubber pad 3, the positioning member 41 is detached, and the operation is completed. Optionally, the connecting portion 411 of the positioning member 41 is a clamp, and the pressing portion 412 is a protruding structure on the side surface of the connecting portion 411. In use, the rubber pad 3 is placed at the preset position on the top of the sleeper 1, and the positioning member 41 is clamped on the sleeper 1 or the spike 11 arranged on the top of the sleeper 1 through the connecting portion 411. After the positioning member 41 is installed in place, the pressing portion 412 abuts against the top of the rubber pad 3. After the rail 2 is placed on the rubber pad 3, the positioning member 41 is detached, and the operation is completed.

[0050] The walking assembly 5 is used to drive the recycling assembly 6 to move along the rail 2 in a preset direction, so that the recycling assembly 6 can be moved to a preset position to detach the positioning members 41. Optionally, the executing member 62 is a sleeve, the rotating output shaft of the power member is coaxially fixed with a threaded rod, and the sleeve is sleeved on the peripheral surface of the threaded rod. The material collecting member 63 is connected with a mechanical arm. After the sleeve unscrews the positioning members 41, the mechanical arm drives the material collecting member 63 to move to a preset position to receive the positioning members 41. Alternatively, the executing member 62 is a mechanical gripper, the power member is an electric mechanical arm, and the material collecting member 63 is an open slot fixed on the top of the walking assembly 5. The positioning members 41 are detached by the mechanical gripper.

[0051] It is worth noting that the types of the positioning members 41 and the recycling assembly 6 are not limited as long as the above functions can be achieved.

[0052] In use, the rubber pads 3 are pre-installed at the preset positions of the new sleepers 1, and the rubber pads 3 on the top of each sleeper 1 are fixed by the auxiliary assembly. After the sleepers 1 are placed in place, the auxiliary assembly is detached by the recycling assembly 6, and the pre-installation device can move to the position of the newly replaced sleeper 1 along the rail 2, and the auxiliary assembly is recycled by the recycling assembly 6, which greatly improves the efficiency of replacing the sleepers 1.

[0053] On the basis of the above embodiment, the recycling assembly 6 further comprises a transmission assembly 64 arranged on the walking assembly 5. The transmission assembly 64 is connected with the power member to drive the annular output member 641 in the transmission assembly 64 to circulate. The top of the positioning member 41 is provided with a plug-in portion 413. The executing member 62 is arranged on the peripheral surface of the output member 641 to be plugged into or detached from the plug-in portion 413. The material collecting member 63 is located on the side of the top of the output member 641 and is moved towards one side to receive the positioning members 41.

[0054] The transmission assembly 64 is driven by the power member, and the transmission assembly 64 can alternatively include a speed reducer, a belt pulley and an output member 641, i.e., the output member 641 adopts a belt, or the transmission assembly 64 includes a speed reducer, a chain wheel and an output member 641, i.e., the output member 641 adopts a chain, and the power member drives the belt pulley or the chain wheel to rotate, so that the annular output member 641 can run in a loop.

[0055] The positioning member 41 is buckled on the top of the sleeper 1 or the spike 11 on the top of the sleeper 1 through the connecting part 411, and the connecting part 411 can be a clamping jaw structure, and the insertion part 413 is a through hole or a groove formed on the top of the positioning member 41; the executing member 62 is fixed on the peripheral surface of the output member 641, so that the executing member 62 can run synchronously with the output member 641, and the part of the executing member 62 matched with the insertion part 413 is parallel to the length direction of the output member 641, so as to be inserted with the insertion part 413 of the positioning member 41 during the loop running of the output member 641, and drive the positioning member 41 to continue to run.

[0056] The material collecting member 63 is located on the side of the top of the conveying member and runs in a predetermined direction, so that the positioning member 41 moving with the executing member 62 on the top of the output member 641 can enter the material collecting member 63, and preferably, the side of the top of the output member 641 running in a direction is lower than the side of the bottom of the output member 641 running in a direction, so that after the positioning member 41 is separated from the sleeper 1 by the insertion and matching of the executing member 62 and the insertion part 413, the positioning member 41 can be driven to move upward from the bottom, which is beneficial to avoid the positioning member 41 from falling.

[0057] As shown in Figure 2 , after the sleeper 1 and the rail 2 are placed in position, the power member is started to drive the output member 641 of the transmission assembly 64 to run in a loop, and at the same time, the positioning member 41 runs synchronously with the output member 641, so that the positioning member 41 in the preset position is separated, and after the positioning member 41 runs to the side where the material collecting member 63 is located, the positioning member 41 falls into the material collecting member 63. The pre-assembly device can autonomously recycle the positioning member 41, and further improve the efficiency of the sleeper 1 replacement.

[0058] Preferably, as shown in Figure 2 , the length direction of the output member 641 is coplanar or parallel to the preset running direction of the walking assembly 5, the extension direction of the insertion part 413 is perpendicular to the length direction of the sleeper 1, and the side of the bottom of the output member 641 running in a direction is the same side as the side of the walking assembly 5 running in a direction according to the preset direction, so that the positioning member 41 can be smoothly separated while the walking assembly 5 moves along the rail 2.

[0059] On the basis of the above-mentioned embodiments, the top of the walking assembly 5 is further provided with a sleeper collecting assembly 7 for disassembling the sleeper 1, a first replacement assembly 8 for placing the sleeper 1, and a second replacement assembly 9 for placing the rail 2; in some embodiments, the second replacement assembly 9, the recycling assembly 6, the first replacement assembly 8, and the sleeper collecting assembly 7 are sequentially arranged along the preset direction of the walking assembly 5; in some embodiments, the recycling assembly 6, the second replacement assembly 9, the first replacement assembly 8, and the sleeper collecting assembly 7 are sequentially arranged along the preset direction of the walking assembly 5.

[0060] Specifically, as shown in Figure 1 the second replacement assembly 9, the recycling assembly 6, the first replacement assembly 8, and the sleeper collecting assembly 7 are sequentially arranged from right to left above the walking assembly 5; in use, the pre-assembly work device runs from right to left under the action of the walking assembly 5, and in the running process, the old sleeper 1 is lifted from the bottom and recycled by the sleeper collecting assembly 7 located on the left side, then the new sleeper 1 is placed at the preset position by the first replacement assembly 8 located in the middle, then the rail 2 is placed on the rubber pad 3 by the second replacement assembly 9, and finally the upper positioning piece 41 of the new sleeper 1 is removed by the recycling assembly 6 located on the right side. Alternatively, the recycling assembly 6, the second replacement assembly 9, the first replacement assembly 8, and the sleeper collecting assembly 7 are sequentially arranged from right to left above the walking assembly 5; in use, the pre-assembly work device runs from right to left under the action of the walking assembly 5, and in the running process, the old sleeper 1 is lifted from the bottom and recycled by the sleeper collecting assembly 7 located on the left side, then the new sleeper 1 is placed at the preset position by the first replacement assembly 8 located in the middle, then the upper positioning piece 41 of the new sleeper 1 is removed by the recycling assembly 6 located on the right side, and finally the rail 2 is placed on the rubber pad 3 by the second replacement assembly 9. In this way, the degree of automation of the pre-assembly work device is effectively improved, and the efficiency of replacing the sleeper 1 is further improved.

[0061] It is worth noting that the sleeper collecting assembly 7, the first replacement assembly 8, and the second replacement assembly 9 mentioned above are all existing devices, and will not be described in detail here.

[0062] On the basis of the above-mentioned embodiments, the number of execution members 62 provided on the actuator 62 corresponding to the output member 641 is greater than or equal to two, and each execution member 62 is uniformly provided on the corresponding output member 641.

[0063] Specifically, as shown in Figure 2 the number of execution members 62 is not limited on the surface of the output member 641, and in use, each execution member 62 is sequentially or intermittently matched with each positioning piece 41, thereby taking each positioning piece 41 away. In this way, the service life of the pre-assembly work device is improved.

[0064] Based on the above embodiments, the connecting part 411 of each positioning member 41 is used to snap onto the corresponding rail spike 11 on the top of the sleeper 1, and the rail spikes 11 on both sides of a rubber pad 3 have corresponding positioning members 41; the number of output members 641 is two, and the two output members 641 are arranged in parallel.

[0065] like Figure 3 As shown, rail spikes 11 are usually provided on both sides of the sleeper 1 where the rubber pad 3 is located. The connecting part 411 can be snapped to the rail spike 11. In this embodiment, two positioning parts 41 are used to position a rubber pad 3. The two output parts 641 are provided with actuators 62 on their circumferential surfaces. In use, the two positioning parts 41 used to position a rubber pad 3 can be simultaneously pulled away by the positioning parts 41 on the circumferential surfaces of the two output parts 641. This setting helps to improve the stability of the rubber pad 3, effectively reduces the possibility of the rubber pad 3 falling off, and the structure is relatively simple.

[0066] Based on the above embodiments, the positioning member 41 is an elastic member, the connecting part 411 has an open structure, and the positioning member 41 is made of elastic steel wire, such as Figures 2 to 4 As shown, the connecting part 411 is an elastic structure with an opening on one side. In use, the size of the opening of the connecting part 411 can be adjusted by external force, so that the positioning member 41 can be snapped onto the rail spike 11 and the positioning member 41 can be removed from the rail spike 11. This setting makes it easy to snap the positioning member 41 onto the rail spike 11 and to detach it from the rail spike 11 by its own elasticity, which helps to protect the rail spike 11.

[0067] Based on the above embodiment, the insertion part 413 has a ring structure, such as... Figures 2 to 4 As shown, in this embodiment, the plug-in part 413 is a ring structure formed by elastic steel wire. Preferably, the plug-in part 413 is located above the connecting part 411. With this arrangement, the structure of the positioning member 41 is simple and easy to manufacture.

[0068] Based on the above embodiment, the pressing part 412 is a bent structure located at the bottom of the insertion part 413. When in use, it abuts against the top of the rubber pad 3, and can be adapted to rubber pads 3 of different thicknesses due to its own elasticity.

[0069] Based on any of the above embodiments, the receiving component 63 is a trapezoidal groove with an open top, such as... Figure 2 As shown, this arrangement facilitates the collection of positioning element 41 and makes it easy to pour out positioning element 41.

[0070] On the basis of any one of the above embodiments, the transmission assembly 64 is arranged on the top of the walking assembly 5 through the base 61; the transmission assembly 64 further comprises a speed reduction assembly, a driving pulley 642 and a driven pulley 643 arranged on the base 61, the power member is connected to the driving pulley 642 through the speed reduction assembly, and the output member 641 is arranged around the circumferential surface of the driving pulley 642 and the driven pulley 643.

[0071] Specifically, as shown in Figure 2 The speed reduction assembly can adopt a speed reduction box or a two-stage gear transmission structure, etc., to transmit the power output by the power member to the driving pulley 642 and the output member 641, and the driven pulley 643 is arranged on the top of the base 61 to support the output member 641, so that the positioning member 41 can be arranged conveniently.

[0084] In some embodiments, after the above step S4, the following steps are performed: first, the recycling assembly 6 is controlled to dismantle and recycle the positioning member 41, i.e. the walking assembly 5 carries the recycling assembly 6 to move to the position of the new sleeper above, and then the recycling assembly 6 starts to run to take the positioning member 41 above the new sleeper off the original position for recycling; and then, the second replacing assembly 9 is controlled to place the steel rail 2 in place, i.e. the walking assembly 5 carries the second replacing assembly 9 to move to the position of the steel rail 2 to be laid, and then the second replacing assembly 9 starts to run to lay the steel rail 2 in place.
