For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0030] Reference Figures 1 to 4 As shown in the drawings, the present application provides a pin dismounting device for a bailey beam, which comprises a connecting frame 2 and a guide frame 1; a moving plate 3 is arranged on the guide frame 1, the moving plate 3 is slidingly installed on the guide frame 1, a striking block 4 is arranged on the moving plate 3, a pull rope 5 for driving the striking block 4 and the moving plate 3 to approach or move away from the connecting frame 2 is arranged on the striking block 4; one end of the connecting frame 2 is connected with the guide frame 1, a striking port 9 for facilitating the striking block 4 to strike the pin is arranged on the connecting frame 2 at a position corresponding to the striking block 4; one end of the guide frame 1 away from the connecting frame 2 is provided with an extrusion lubricating mechanism, the extrusion lubricating mechanism comprises a lubricating capsule 16, the lubricating capsule 16 is filled with lubricating liquid, one end of the lubricating capsule 16 facing the moving plate 3 is provided with a liquid discharge pipe 20 for guiding the lubricating liquid to the sliding fit position of the moving plate 3 and the guide frame 1, and the liquid discharge pipe 20 is in communication with the lubricating capsule 16.

[0031] The impact block 4 can be made of high-hardness wear-resistant steel, the pull rope 5 can be fixed on the impact block 4 by connecting rings, screw connections and the like, and the surface of the impact block 4 can be polished to reduce self-wear during impact and prolong service life. In addition, the upper portion of the connecting frame 2 is provided with an impact opening 9 which is adapted in size to the impact block 4 or to the pin, so as to meet the impact requirement of the impact block 4 on the pin during movement and facilitate the impact block 4 to impact and disassemble the pin of the Bailey beam.

[0032] In this embodiment, the connecting frame 2 and the guide frame 1 can be fixedly connected or detachably connected, or integrally formed. For example, the connecting frame 2 and the guide frame 1 can be fixedly connected by welding, bonding, screw connection and the like. It should be understood that other connection modes can also be adopted by those skilled in the art according to actual needs to achieve stable connection between the connecting frame 2 and the guide frame 1, which will not be described here.

[0033] In actual application, the connecting frame 2 and the Bailey beam can be connected by insertion, clamping, screw connection and the like. It should be noted that when the connecting frame 2 is installed on the Bailey beam, the impact opening 9 on the connecting frame 2 needs to be aligned with the pin of the Bailey beam to facilitate subsequent impact and disassembly of the pin by the impact block 4.

[0034] This disassembly device can be used according to the following steps: first, the connecting frame 2 is connected with the Bailey beam. Then, the moving plate 3 is moved away from the connecting frame 2, and then the pull rope 5 is used to pull the impact block 4 to drive the impact block 4 and the moving plate 3 to move quickly towards the connecting frame 2 until the impact block 4 impacts the pin. Then, the pull rope 5 can be used to drive the impact block 4 and the moving plate 3 to reset, and the pull rope 5 can be repeatedly used to drive the impact block 4 to impact the pin until the pin is disassembled from the Bailey beam.

[0035] It should be noted that during the process of resetting the moving plate 3 by the pull rope 5, the moving plate 3 can also be used to impact and extrude the lubricating capsule 16 to extrude the lubricating liquid in the lubricating capsule 16 into the drain pipe 20, and finally flow into the sliding fit between the moving plate 3 and the guide frame 1 through the drain pipe 20, so that the lubricating liquid can fully lubricate the sliding fit between the moving plate 3 and the guide frame 1. In this way, it can effectively avoid the moving plate 3 from being stuck or dead during repeated movement, which is conducive to improving the impact and disassembly effect of the impact block 4 on the pin and improving the disassembly efficiency of the device on the pin of the Bailey beam.

[0036] In an alternative embodiment, reference is made to Figure 1 and Figure 2The guide frame 1 is provided with a containing groove 6, and the moving plate 3 is at least partially located in the containing groove 6. The length direction of the containing groove 6 is the same as the moving direction of the moving plate 3. One end of the liquid discharge pipe 20 is communicated with the containing groove 6, and the other end is communicated with the lubricating capsule 16. By communicating the liquid discharge pipe 20 with the containing groove 6, when the moving plate 3 impacts and extrudes the lubricating capsule 16, the lubricating liquid can flow into the containing groove 6 through the liquid discharge pipe 20. The lubricating liquid can be lubricating oil or other lubricating liquid, as long as it can play a lubricating role on the sliding fit part of the moving plate 3 and the guide frame 1.

[0037] In actual application, the moving plate 3 can be completely located in the containing groove 6, or partially located in the containing groove 6 and partially extended out of the containing groove 6. By setting the moving plate 3 at least partially in the containing groove 6, the containing groove 6 can not only play a good limiting and guiding role on the moving plate 3, but also ensure that the moving plate 3 can always stably slide on the guide frame 1. In addition, the containing groove 6 can also be used to contain the lubricating liquid discharged through the liquid discharge pipe 20, so that the lubricating liquid can accumulate in the containing groove 6. In this way, the lubricating liquid can continuously play a lubricating role between the moving plate 3 and the guide frame 1, and ensure the smoothness of the moving plate 3 when repeatedly moving.

[0038] In an alternative embodiment, referring to Figure 1 and Figure 2 The guide frame 1 is provided with a guide groove 7 corresponding to the positions of the two sides of the moving plate 3. The moving plate 3 is partially located in the guide groove 7. The length direction of the guide groove 7 is the same as the moving direction of the moving plate 3. The liquid discharge pipe 20 is located between the side wall of the moving plate 3 and the inner side wall of the guide groove 7. The side of the liquid discharge pipe 20 facing the moving plate 3 is provided with a liquid discharge port 21. The guide groove 7 is provided with two corresponding to the left and right sides of the moving plate 3. The left and right sides of the moving plate 3 respectively extend into the corresponding guide groove 7, so that the moving plate 3 can be partially located in the guide groove 7. Correspondingly, the liquid discharge pipe 20 is also provided with two corresponding to the guide groove 7, so as to realize synchronous lubrication of the left and right sides of the moving plate 3. By setting the liquid discharge port 21 towards the moving plate 3, the lubricating liquid can be directly discharged to the sliding fit part of the moving plate 3 and the guide frame 1, thereby avoiding waste of lubricating liquid.

[0039] In actual application, the guide groove 7 is used to guide and limit the left and right sides of the moving plate 3, which is conducive to further improving the stability of the moving plate 3 when moving, and avoiding the moving plate 3 from coming out of the guide frame 1, facilitating the operator to repeatedly move and impact the impact block 4 and the moving plate 3 by using the pull rope 5. At the same time, by setting the liquid discharge pipe 20 between the side wall of the moving plate 3 and the inner side wall of the guide groove 7, it can be ensured that the liquid discharge pipe 20 will not interfere with the movement of the moving plate 3, and the lubricating liquid discharged by the liquid discharge pipe 20 can directly act on the sliding fit part of the moving plate 3 and the guide frame 1, which is conducive to improving the lubricating effect of the lubricating liquid.

[0040] In this embodiment, the length direction of the drain pipe 20 is the same as the length direction of the guide groove 7, and the drain ports 21 are arranged in multiple along the length direction of the drain pipe 20. In this way, the multiple drain ports 21 can realize the dispersed discharge of the lubricating oil, so that the lubricating oil is dispersedly flowed into the guide groove 7 along the moving direction of the moving plate 3, which is beneficial to further improve the uniformity of the lubricating oil in the guide groove 7 and ensure the smooth movement of the moving plate 3 along the guide groove 7.

[0041] It should be understood that the containing groove 6 and the guide groove 7 can be arranged on the guide frame 1 at the same time, and the containing groove 6 and the guide groove 7 are communicated, so that the moving plate 3 can be kept stable under the double guide and limiting of the containing groove 6 and the guide groove 7, avoiding the situation that the moving plate 3 is jammed or stuck due to deviation, which is beneficial to further improve the stability of the moving plate 3 during movement and improve the reliability of the device during use.

[0042] In an alternative embodiment, referring to Figure 3 The moving plate 3 is provided with a roller 17, the roller 17 is rotatably installed on the moving plate 3, and the roller 17 is located between the moving plate 3 and the guide frame 1. For example, the roller 17 can be uniformly arranged four or more on the bottom surface of the moving plate 3, the roller 17 can be uniformly arranged four or more around the moving plate 3, or the person skilled in the art can also select a suitable position to arrange the roller 17 according to actual needs, as long as the roller 17 can be located between the moving plate 3 and the guide frame 1 and can change the sliding friction into rolling friction. Herein, no further description is made.

[0043] In actual application, the roller 17 can be rotatably installed on the moving plate 3 through a wheel frame 18, wherein the wheel frame 18 can be installed and fixed on the moving plate 3 by bonding, welding, screw connection or the like, and the roller 17 can be rotatably installed on the wheel frame 18 by a rotating shaft or the like. By arranging the rotatable roller 17 on the moving plate 3, it is beneficial to further reduce the friction between the moving plate 3 and the guide frame 1 and improve the smoothness of the moving plate 3 during movement.

[0044] It should be understood that in some other embodiments of the present application, the roller 17 can also be rotatably installed on the moving plate 3 by a rotating shaft or the like, the moving plate 3 is provided with an assembly groove for installing the roller 17, the moving plate 3 is provided with an axle hole matched with the rotating shaft at a position corresponding to the assembly groove, and the axle hole is communicated with the assembly groove. At this time, even if the wheel frame 18 in the foregoing embodiment is not provided, the roller 17 can also be rotatably installed on the moving plate 3, so the person skilled in the art can also select other ways to install the roller 17 according to actual needs, and no further description is made herein.

[0045] In an alternative embodiment, referring to Figure 2 and Figure 4The guide frame 1 is provided with a containing cavity, and the lubricating bag 16 is located in the containing cavity. The guide frame 1 is provided with a connecting pipe 19 corresponding to the containing cavity. One end of the connecting pipe 19 extends into the containing cavity and is in communication with the lubricating bag 16, and the other end is in communication with a liquid discharge pipe 20.

[0046] The lubricating bag 16 is provided with a liquid inlet pipe 23. The guide frame 1 is provided with a through hole for the liquid inlet pipe 23 to extend out. The through hole is in communication with the containing cavity. One end of the liquid inlet pipe 23 is provided with a detachable sealing cover 8, and the other end is in communication with the lubricating bag 16. It should be understood that the sealing cover 8 can be assembled on the liquid inlet pipe 23 by means of screw connection, clamping, flange connection or other detachable mounting modes. The connecting pipe 19 and the lubricating bag 16, and the connecting pipe 19 and the liquid discharge pipe 20 can be connected by means of one-piece forming, bonding, plug-in, threaded connection or other connection modes.

[0047] In actual application, the lubricating bag 16 can be made of flexible materials such as rubber or silicone, and has a cavity for containing lubricating liquid. The liquid inlet pipe 23 and the liquid discharge pipe 20 are in communication with the cavity, and the cavity is filled with lubricating liquid. In this way, when the moving plate 3 hits and extrudes the lubricating bag 16 to deform, the cavity in the lubricating bag 16 becomes smaller, and the lubricating liquid is extruded to flow out of the liquid discharge pipe 20, so as to realize lubrication of the sliding fit between the moving plate 3 and the guide frame 1.

[0048] In this embodiment, the extrusion lubricating mechanism includes a push frame 22 located between the lubricating bag 16 and the moving plate 3. The push frame 22 is slidingly installed on the guide frame 1, and the sliding direction of the push frame 22 is the same as the moving direction of the moving plate 3. The guide frame 1 is provided with a guide hole matched with the push frame 22. The guide hole is in communication with the containing cavity. One end of the push frame 22 extending into the containing cavity is provided with an extrusion plate 15 capable of extruding the lubricating bag 16, and the other end is provided with a push plate 13 capable of cooperating with the moving plate 3. The extrusion lubricating mechanism further includes an elastic element 14. One end of the elastic element 14 abuts against the guide frame 1, and the other end abuts against the push plate 13.

[0049] In actual application, the elastic element 14 can be a compression spring or other elastic element. For example, the compression spring can be sleeved on the push frame 22, and other elastic elements can be installed by abutting, bonding or screw connection. The extrusion plate 15 and the push frame 22, and the push plate 13 and the push frame 22 can be connected by bonding, threaded connection or screw connection, so that the push plate 13 can drive the push frame 22 to move, and the push frame 22 can drive the extrusion plate 15 to move, so as to extrude the lubricating bag 16.

[0050] When the moving plate 3 moves away from the connecting frame 2, the moving plate 3 can drive the pushing frame 22 to move by impacting the pushing plate 13, extruding the elastic element 14 and driving the extruding plate 15 to extrude the lubricating capsule 16, so that the lubricating liquid can be discharged from the discharge pipe 20 to the sliding fit position of the moving plate 3 and the guide frame 1. When the moving plate 3 stops moving, the pushing plate 13 can be reset under the action of the reset elastic force of the elastic element 14, so that the extruding plate 15 is separated from the lubricating capsule 16, facilitating the recovery of the lubricating capsule 16 for subsequent extrusion of the lubricating liquid. Meanwhile, the pushing plate 13 can also provide starting assistance for the movement, and cooperate with the pulling effect of the pulling rope 5 on the moving plate 3, which is beneficial to improve the initial speed of the moving plate 3, and further improve the impact dismounting effect of the impact block 4 on the pin.

[0051] In an alternative embodiment, referring to Figure 1 and Figure 2 The connecting frame 2 is provided with a reset driving mechanism for driving the moving plate 3 to move away from the connecting frame 2, and the reset driving mechanism comprises a telescopic cylinder 10 and a pushing plate 11. The fixed end of the telescopic cylinder 10 is arranged on the connecting frame 2, the pushing plate 11 is located between the moving plate 3 and the telescopic cylinder 10, and the pushing plate 11 is arranged on the telescopic end of the telescopic cylinder 10. For example, the telescopic cylinder 10 can adopt a telescopic mechanism such as a pneumatic cylinder or an electric telescopic rod, and the fixed end of the telescopic cylinder 10 can be fixed on the connecting frame 2 by screws or the like. The pushing plate 11 can also be fixed on the telescopic end of the telescopic cylinder 10 by screws or the like, and the connecting frame 2 can be provided with a sliding hole 12 for accommodating the pushing plate 11. The size of the sliding hole 12 matches the size of the pushing plate 11, and the pushing plate 11 can be made of rubber, plastic or the like to provide good protection for the moving plate 3. It should be understood that the telescopic cylinder 10 can be provided with one or more, but the telescopic direction of the telescopic cylinder 10 should be opposite to the moving direction of the moving plate 3.

[0052] In actual application, taking the telescopic cylinder 10 as a pneumatic cylinder for example, when the moving plate 3 moves to the connecting frame 2, the pushing plate 11 can be driven to move by the pneumatic cylinder, so that the pushing plate 11 can push the moving plate 3 away from the connecting frame 2, so that the operator does not need to use the pulling rope 5 to drive the impact block 4 and the moving plate 3 to reset, facilitating the operator to use the pulling rope 5 to drive the impact block 4 to impact the pin again, which is beneficial to improve the dismounting efficiency of the pin. It should be understood that the working principles of other telescopic cylinders 10 are the same, that is, to drive the pushing plate 11 to move to push the moving plate 3 away from the connecting frame 2, which will not be described here.

[0053] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
