[0028] As described in the background, long-distance maneuver of tracked equipment mainly relies on railway transportation, and the existing binding and reinforcing material is mainly steel wire rope. It is difficult to control the tightness of the steel wire rope binding, and it is necessary to use a steel wire rope fastener, a manual hoist and the like for fastening, which is more complicated to operate, requires a long binding and reinforcing time, has high labor intensity and high economic cost, and affects and restricts the maneuvering efficiency of tracked equipment.

[0029] The present application will be described in detail below through one or more specific embodiments.

[0030] In some embodiments, a binding and reinforcing device for railway transportation of tracked equipment, as shown in Figure 1 , Figure 2 and Figure 3 , comprises a hanging ring hook 10, a first binding chain 20, a tensioner 30, a second binding chain 40 and a shackle hook 50 connected in sequence;

[0031] One end of the hanging ring hook 10 is a hanging ring structure 11 for connecting with the fastening point of the railway flat car, and the other end is a hook structure 12 connected with the first binding chain 20;

[0032] The shackle hook 50 is connected with the second binding chain 40 and is used to connect with the fastening point of the tracked equipment;

[0033] The tensioner 30 comprises an inner sleeve 31, an intermediate sleeve 32 and an outer sleeve 33, the intermediate sleeve 32 is sleeved on the periphery of the inner sleeve 31 and is threadedly connected with the inner sleeve 31, the outer sleeve 33 is sleeved on the periphery of the intermediate sleeve 32 and is threadedly connected with the intermediate sleeve 32, the inner sleeve 31 is connected with the second binding chain 40 at one end outside the intermediate sleeve 32, and the outer sleeve 33 is connected with the first binding chain 20 at an end away from the opening thereof;

[0034] When the intermediate sleeve 32 of the tensioner 30 is rotated, the length of the tensioner 30 is shortened or lengthened to control the length of the binding reinforcement.

[0035] Specifically, the ring hook 10 is fixedly connected with the fastening point of the railway flat car, and the shackle hook 50 is fixedly connected with the fastening point of the tracked equipment, that is, the ring hook 10 and the shackle hook 50 are both tethering components to connect the railway flat car with the object carried thereby and to connect the tracked equipment with other carrying vehicles, which is beneficial to the confirmation of the fastening point and improves the efficiency of binding the tracked equipment on the railway flat car, thereby improving the transportation efficiency of the tracked equipment.

[0036] The first binding chain 20 connects the tensioner 30 with the ring hook 10, and the second binding chain 40 connects the shackle hook 50 with the tensioner 30, and the tensioner 30 can adjust its own length to adjust the length of the binding reinforcement, thereby realizing the binding and reinforcement of the tracked equipment on the railway flat car by the binding reinforcement through the tensioner 30.

[0037] The tensioner 30 comprises the inner sleeve 31, the intermediate sleeve 32 and the outer sleeve 33 which are threadedly connected in sequence, and when the inner sleeve 31 or the intermediate sleeve 32 or the outer sleeve 33 is rotated, the length of the tensioner 30 is shortened or lengthened, thereby realizing the length change of the binding reinforcement.

[0038] It should be noted that when the inner sleeve 31 or the outer sleeve 33 is rotated, the first binding chain 20 or the second binding chain 40 will rotate with the outer sleeve 33 or the inner sleeve 31 because the inner sleeve 31 is connected with the second binding chain 40 and the outer sleeve 33 is connected with the first binding chain 20, which is not conducive to the length adjustment efficiency of the tensioner 30, therefore, when the length of the tensioner 30 is adjusted, the length adjustment is realized by rotating the intermediate sleeve 32.

[0039] In addition, the connection relationship between the inner sleeve 31 and the outer sleeve 33 and the first binding chain 20 and the second binding chain 40 is not fixed, the inner sleeve 31 can be connected with the first binding chain 20, and can also be connected with the second binding chain 40, and the outer sleeve 33 is the same. When the inner sleeve 31 is connected with the first binding chain 20, the outer sleeve 33 is connected with the second binding chain 40.

[0040] In the embodiment, by arranging the sequentially connected ring hook 10, the first binding chain 20, the tensioner 30, the second binding chain 40 and the shackle hook 50, and connecting the ring hook 10 with the fixing point of the railway flat car and connecting the shackle hook 50 with the fixing point of the tracked equipment, the tracked equipment is bound on the railway flat car. On this basis, by rotating the middle sleeve 32, the inner sleeve 31 or the outer sleeve 33 of the tensioner 30 to adjust the length of the tensioner 30, the length adjustment of the binding reinforcement device is realized, so as to reinforce the binding of the tracked equipment and the railway flat car, so that the tracked equipment is stably connected with the railway flat car. The binding and reinforcing process of the binding reinforcement device provided by the application is simple, which is beneficial to improving the connection efficiency of the tracked equipment and the railway flat car, and is suitable for popularization and application.

[0041] In some embodiments, as shown in Figure 3 The inner sleeve 31 is provided with a first connecting portion 311 at one end outside the middle sleeve 32, the first connecting portion 311 is provided with a first connecting through hole 312, and the second binding chain 40 is connected with the inner sleeve 31 through the first connecting through hole 312.

[0042] The outer sleeve 33 is provided with a second connecting portion 331 at one end away from the opening, the second connecting portion 331 is a U-shaped structure, the opening of the U-shaped structure is arranged towards the first binding chain 20, the U-shaped structure is provided with two opposite second connecting through holes 332, the first binding chain 20 is located between the two second connecting through holes 332 through the opening, and the tensioner 30 pin shaft passes through the second connecting through hole 332 and the first binding chain 20 at the same time, so as to connect the first binding chain 20 with the outer sleeve 33.

[0043] Specifically, the first binding chain 20 and the second binding chain 40 are both ring chains composed of a plurality of chain links connected with each other. The first connecting portion 311 is a plate-shaped structure, and the first connecting through hole 312 is arranged on the plate-shaped structure to connect with the second binding chain 40. The second connecting portion 331 is a U-shaped structure, and the opening of the U-shaped structure is used for entering a chain link of the first binding chain 20. The second connecting through hole 332 is arranged on the opposite side wall of the U-shaped structure, and the second connecting through holes 332 are oppositely arranged. The pin shaft of the tensioner 30 passes through the second connecting through hole 332, the chain link of the first binding chain 20 and the other second connecting through hole 332 in sequence, so that the outer sleeve 33 is connected with the first binding chain 20.

[0044] In the embodiment, the structure of the inner sleeve 31 and the outer sleeve 33 of the tensioner 30 is described in detail to clarify the specific connection structure of the inner sleeve 31 and the outer sleeve 33 with the second binding chain 40 and the first binding chain 20. The connection mode of the two ends of the tensioner 30 is different to improve the connection diversity of the tensioner 30 and improve the connection practicability of the tensioner 30.

[0045] In some embodiments, as shown in Figure 3 The outer periphery of the intermediate sleeve 32 is provided with the protruding ring 321, and the protruding ring 321 is arranged close to the first connecting portion 311.

[0046] Specifically, the protruding ring 321 is arranged on the intermediate sleeve 32, the first connecting portion 311 is arranged on the inner sleeve 31 and outside the intermediate sleeve 32, the protruding ring 321 is arranged on the outer periphery of the intermediate sleeve 32 and close to the opening of the intermediate sleeve 32 for the inner sleeve 31 to pass through. The arrangement of the protruding ring 321 can facilitate the user to rotate the intermediate sleeve 32 to adjust the length of the tensioner 30, thereby improving the adjustment convenience of the tensioner 30. In addition, the protruding ring 321 can also limit the sleeving range of the outer sleeve 33 on the outer periphery of the intermediate sleeve 32, which is conducive to controlling the sleeving length of the outer sleeve 33 on the intermediate sleeve 32, thereby being conducive to controlling the length of the tensioner 30.

[0047] In some embodiments, as shown in Figure 3 The inner side wall of the outer sleeve 33 is provided with the felt ring 333, and the felt ring 333 is arranged close to the opening of the outer sleeve 33.

[0048] Specifically, the inner side wall of the outer sleeve 33 is provided with the felt ring 333, so that part of the inner side wall of the outer sleeve 33 is in contact with the intermediate sleeve 32 through the felt ring 333. The felt ring 333 can increase the connection sealing between the inner side wall of the outer sleeve 33 and the outer side wall of the intermediate sleeve 32, thereby avoiding external liquid from entering between the outer side wall of the intermediate sleeve 32 and the inner side wall of the outer sleeve 33, affecting the connection smoothness of the intermediate sleeve 32 and the outer sleeve 33, and thereby facilitating the improvement of the service life of the tensioner 30.

[0049] The felt ring 333 is arranged close to the opening of the outer sleeve 33, which can avoid the felt ring 333 affecting the threaded connection of the outer sleeve 33 and the intermediate sleeve 32, and can also seal the opening of the outer sleeve 33, thereby ensuring the stable connection of the outer sleeve 33 and the intermediate sleeve 32, sealing the connection of the outer sleeve 33 and the intermediate sleeve 32, and facilitating the improvement of the service life of the tensioner 30.

[0050] In some embodiments, as shown in Figure 4 The shackle hook 50 includes an X-shaped connecting portion 51 and a U-shaped connecting portion 52. One end of the X-shaped connecting portion 51 is connected to the second binding chain 40 through a first pin shaft 53, and the other end of the X-shaped connecting portion 51 and the U-shaped connecting portion 52 are connected through a second pin shaft 54. The U-shaped connecting portion 52 is used to be connected to a tie point of the tracked equipment.

[0051] Specifically, one end of the X-shaped connecting portion 51 of the shackle hook 50 is used to be connected to the second binding chain 40, and the other end is used to be connected to the U-shaped connecting portion 52. The U-shaped connecting portion 52 is used to be connected to a tie point of the tracked equipment. The connection between the X-shaped connecting portion 51 and the second binding chain 40 is realized through the first pin shaft 53, that is, the X-shaped connecting portion 51 is provided with opposite through holes on two connecting walls of one end of the second binding chain 40. The link of the second binding chain 40 is located between the two connecting walls, and the first pin shaft 53 penetrates the link and the two connecting walls to connect the X-shaped connecting portion 51 and the second binding chain 40. The connection between the X-shaped connecting portion 51 and the U-shaped connecting portion 52 is the same. The X-shaped connecting portion 51 and the U-shaped connecting portion 52 are connected through the second pin shaft 54. That is, the X-shaped connecting portion 51 is provided with opposite through holes on two connecting walls of one end of the U-shaped connecting portion 52. The opposite two side walls of the opening of the U-shaped connecting portion 52 are also provided with opposite through holes. The one end of the X-shaped connecting portion 51 connected to the U-shaped connecting portion 52 is located between the two side walls of the U-shaped connecting portion 52. The second pin shaft 54 penetrates the through holes of the U-shaped connecting portion 52 and the X-shaped connecting portion 51 to connect the X-shaped connecting portion 51 and the U-shaped connecting portion 52 together.

[0052] It should be noted that the connection of the X-shaped connecting part 51 and the U-shaped connecting part 52 is detachable, so that the connection of the shackle hook 50 and the tie-down point of the tracked equipment is detachable, thereby facilitating the user to take off the shackle hook 50 from the tracked equipment. When the binding and tie-down of the tracked equipment needs to be continuously interrupted, the second binding chain 40 is only disconnected from the shackle hook 50, the shackle hook 50 is thrown on the tie-down point of the tracked equipment, and the first pin shaft 53 is removed, so that the binding and reinforcement of the tracked equipment can be quickly released. When the tracked equipment needs to be bound and reinforced, the second binding chain 40 is only connected to the shackle hook 50 through the first pin shaft 53, so that the binding and tie-down of the tracked equipment by the binding and reinforcement device can be realized.

[0053] In some embodiments, as shown in Figure 2 The hook structure 12 of the shackle hook 10 is connected to the first binding chain 20 through a third pin shaft 13.

[0054] Specifically, one end of the shackle hook 10 is a shackle structure 11, and the other end is a hook structure 12. The shackle structure 11 is connected to the tie-down point of the railway flat car. The shackle structure 11 has no opening, so the connection between the shackle structure 11 and the tie-down point of the railway flat car is continuous. The tie-down point of the railway flat car is connected to the binding and reinforcement device through the hook structure 12 of the shackle hook 10, which is beneficial to improve the stability of the tie-down of the binding and reinforcement device and the tie-down point of the railway flat car.

[0055] The opening of the hook structure 12 is arranged towards the first binding chain 20. The link of the first binding chain 20 is located between the two opposite side walls of the hook structure 12 through the opening. The two opposite through holes are arranged on the two side walls of the hook structure 12. The third pin shaft 13 penetrates the two side walls of the hook structure 12 and the link of the first binding chain 20, so as to connect the first binding chain 20 and the hook structure 12 of the shackle hook 10. Thus, the first binding chain 20 is connected to the shackle hook 10 through the third pin shaft 13, and the first binding chain 20 is stably connected to the shackle hook 10, which is beneficial to improve the binding stability of the binding and reinforcement device.

[0056] In some embodiments, as shown in Figure 1 The binding and reinforcement device further comprises a chain shortener 60. The length of the first binding chain 20 is smaller than the length of the second binding chain 40. The chain shortener 60 is located between the tensioner 30 and the second binding chain 40. The tensioner 30 is connected to the second binding chain 40 through the chain shortener 60.

[0057] Specifically, the length of the second binding chain 40 is much greater than the length of the first binding chain 20, the first binding chain 20 is used to connect the hanging ring hook 10 and the tensioner 30, and the second binding chain 40 is the main structure of the binding reinforcement device, therefore, the chain shortener 60 is connected to the second binding chain 40 to shorten the second binding chain 40, so as to realize the binding and reinforcement of the binding reinforcement device.

[0058] One end of the chain shortener 60 is a locking end 61, and the other end is an adjusting end 62, the adjusting end 62 is connected with the inner sleeve 31 of the tensioner 30, and the locking end 61 is connected with the second binding chain 40, the chain ring connected with the second binding chain 40 at the locking end 61 can be adjusted through the adjusting end 62, so as to realize the length adjustment of the second binding chain 40, and thus the length adjustment of the binding reinforcement device. By shortening the length of the second binding chain 40 through the chain shortener 60, the binding and reinforcement of the binding reinforcement device on the tracked equipment is realized, and on this basis, the adjustment of the tensioner 30 can further improve the binding and reinforcement of the binding reinforcement device. The adjustment of the chain shortener 60 is a large adjustment, and the adjustment of the tensioner 30 is a fine adjustment. The joint action of the chain shortener 60 and the tensioner 30 improves the binding and reinforcement effect of the binding reinforcement device in use, and thus improves the practicability of the binding reinforcement device.

[0059] It should be noted that the chain shortener 60 is a common structure in the field of rigging, and its specific use principle will not be described in detail.

[0060] For example, the chain shortener 60 is a VMWK chain shortener 60.

[0061] In some embodiments, as shown in Figure 1 As shown, the binding reinforcement device further comprises a suspension chain 70, one end of the suspension chain 70 is detachably connected with the second binding chain 40, and the other end is used to connect the excess chain of the second binding chain 40 shortened by the chain shortener 60.

[0062] Specifically, the suspension chain 70 is detachably connected with the second binding chain 40, so that the user can adjust the position of the suspension chain 70 on the second binding chain 40, avoid affecting the action of the chain shortener 60 on the second binding chain 40 when the suspension chain 70 is connected with the second binding chain 40, and improve the flexibility of the binding reinforcement device.

[0063] The suspension chain 70 can be detachably connected with the second binding chain 40 through a connecting buckle (similar to a safety buckle).

[0064] The other end of the hanging chain 70 is a free end, provided with a connecting buckle (similar to a safety buckle), and the excess chain of the second binding chain 40 shortened by the chain shortener 60 is connected to the hanging chain 70 through the connecting buckle, so as to avoid the excess chain of the second binding chain 40 shortened by the chain shortener 60 to be placed randomly on the chain shortener 60, affecting the binding and reinforcing effect of the binding reinforcing device, and affecting the further shortening effect of the chain shortener 60 on the second binding chain 40. The hanging chain 70 is beneficial to the stability of the chain shortener 60, and further beneficial to the practicability of the binding reinforcing device.

[0065] In some embodiments, the hanging chain 70 is arranged close to the chain shortener 60.

[0066] Specifically, the arrangement of the hanging chain 70 close to the chain shortener 60 can facilitate the connection of the hanging chain 70 and the excess chain of the second binding chain 40 shortened by the chain shortener 60, and further facilitate the function of the hanging chain 70.

[0067] In some embodiments, as shown in Figure 1 The binding reinforcing device further comprises a chain detection card 80, which is detachably connected with the second binding chain 40 or the first binding chain 20.

[0068] Specifically, the chain detection card 80 is detachably connected with the second binding chain 40 or the first binding chain 20 through a connecting buckle (similar to a safety buckle). The chain detection card 80 is a card structure, one side edge of which is provided with a diameter detection groove 81 with a width equal to the maximum diameter of the chain link of the first binding chain 20 and the second binding chain 40, the other side edge is provided with a wear detection groove 82 with a width equal to the diameter of the chain link body (i.e. the diameter of the rod-shaped structure constituting the chain link) of the first binding chain 20 and the second binding chain 40, and the free end is a detection end 83 with a width equal to the maximum distance between two adjacent chain links of the first binding chain 20 and the second binding chain 40. When the chain link cannot be clamped into the diameter detection groove 81 along the length direction, it indicates that the plastic deformation of the chain link is too large to exceed the limit value, and the chain link should be stopped using. When the wear part of the chain link can be easily clamped into the wear detection groove 82, it indicates that the diameter of the chain link is seriously worn and should be stopped using. When the detection end 83 can be easily clamped between two chain links along the width direction, it indicates that the wear and plastic deformation of the chain link exceed the limit value, and the chain link should be stopped using.

[0069] In the embodiment, by arranging the chain detection card 80, the first bundling chain 20 and the second bundling chain 40 of the bundling reinforcement device can be detected conveniently, so that the wear conditions of the first bundling chain 20 and the second bundling chain 40 can be found in time, and the bundling reinforcement device can be prevented from performing the bundling reinforcement action when the first bundling chain 20 and the second bundling chain 40 are seriously worn, thereby being favorable for guaranteeing the bundling reinforcement effect of the bundling reinforcement device, avoiding the bundling reinforcement failure, and guaranteeing the railway transportation safety of the tracked equipment.
