Description

Technical Field

[0001] The utility model relates to the technical field of railway turnouts, and particularly to a self-limiting pad fastener tray. Background Technique

[0002] In railway turnouts, the pad fasteners mainly consist of components such as T-bolts, nuts, elastic bars, washers, etc. When installing the pad fasteners, they usually need to be transported to the laying site, and materials are taken one by one, combined and assembled. However, due to the large variety of components of the pad fasteners, it is necessary to take materials back and forth many times during transportation, which is extremely easy to cause the components to fall during transportation and the phenomenon that various types of fasteners are scattered. The transportation efficiency is low, which affects the laying progress. At the same time, the scattered components on site are not easy to manage, and the assembly efficiency is low.

[0003] To solve the above problems, for example, the Chinese utility model patent CN219278157U discloses a turnout fastener complete set device, including: a material rack, the material rack includes a frame body and a material rack table supported by the frame body, and a groove is provided on the material rack table; a turnout fastener, the turnout fastener includes a pre-installed bolt, gasket and nut, the turnout fastener further includes an elastic bar, the bolt extends into the groove, the elastic bar abuts against the upper surface of the groove, the gasket is located above the elastic bar, and the nut is located above the gasket. The turnout fastener complete set device provided by the utility model is used for the accurate distribution of the complete set of materials after the overall pre-installation of the turnout fasteners, and can realize the accurate taking of the turnout fasteners; it avoids the phenomenon that the parts of the turnout fasteners are scattered and not easy to manage at the laying site, and is easy to count and manage.

[0004] However, in the actual use process of the above device, the following problems exist: 1. In some cases, it may only be necessary to take the T-bolt in the pad fastener, but the above device can only accurately distribute the complete set of materials after the overall pre-installation of the pad fasteners, and can only take the overall pre-installed parts of the pad fasteners when taking them, with poor flexibility; 2. The pad fasteners have various specifications and models, but in the above device, only the pad fasteners that can pass through the groove vertically can be transported. Limited by the width of the groove, the applicable range is narrow; 3. When transporting in an inclined state or when the road conditions are poor, the pad fasteners are easy to fall from the groove, and the reliability during transportation is poor; 4. After the T-bolt on the pad fastener passes through the groove, once affected by vibration, if the T-bolt rotates relative to the groove, it is also necessary to rotate the T-bolt back to its original position when taking it, and the taking efficiency is low. Content of the Utility Model

[0005] The utility model provides a self-limiting pad fastener tray to solve the technical problems of poor flexibility, narrow applicable range, poor reliability and low taking efficiency of the existing pad fastener transportation tools.

[0006] According to one aspect of the present utility model, a self-limiting backing plate fastener tray is provided for transporting backing plate fasteners. The backing plate fastener includes a T-shaped bolt. The tray includes a transport main body, a first transport groove opened in the transport main body for accommodating the head of the T-shaped bolt, and a second transport groove opened on the transport main body and penetrating the transport main body for accommodating the shank of the T-shaped bolt. The first transport groove and the second transport groove communicate with each other and are arranged in a T shape. The groove width of the first transport groove is greater than that of the second transport groove. The first transport groove is provided with a limiting end for limiting the head of the T-shaped bolt after rotating a preset angle and a movable end for taking out the T-shaped bolt along the length direction of the first transport groove. The groove width of the limiting end is less than that of the movable end.

[0007] As a further improvement of the above technical solution:

[0008] Further, a plurality of first transport grooves are provided, and the plurality of first transport grooves are arranged at intervals in the transport main body, and the first transport grooves and the second transport grooves are arranged in one-to-one correspondence.

[0009] Further, a hollow groove is opened on the transport main body, and the hollow groove and the plurality of first transport grooves are arranged in a staggered manner.

[0010] Further, the hollow groove is arranged between two adjacent first transport grooves. Limiting grooves communicating with the adjacent first transport grooves are opened on both side walls of the hollow groove. The limiting grooves are used to enable the head of the T-shaped bolt to enter the adjacent first transport groove after the T-shaped bolt is accommodated in the hollow groove, so as to limit the T-shaped bolt in the first transport groove.

[0011] Further, a plurality of hollow grooves are provided, and the plurality of hollow grooves are arranged at intervals on the transport main body.

[0012] Further, the groove widths of the plurality of hollow grooves are different.

[0013] Further, the tray includes a plurality of transport main bodies stacked vertically.

[0014] Further, stacking bosses corresponding to the hollow grooves of the adjacent transport main bodies are opened on the bottom of the transport main body. The lower end of the stacking boss is arranged obliquely and is used to partially embed into the hollow groove. The adjacent two transport main bodies are stacked by the stacking bosses.

[0015] Further, a plurality of stacking bosses are provided, and the plurality of stacking bosses are arranged in a square array on the bottom of the transport main body.

[0016] Further, the connection part between the first transport groove and the second transport groove is arranged with a chamfer.

[0017] The present utility model has the following beneficial effects:

[0018] The self-limiting backing plate fastener tray of the present utility model accommodates the head of the T-bolt through the first transfer groove opened in the transfer main body. The head of the T-bolt is accommodated through the first transfer groove opened on and penetrating the transfer main body. And after the T-bolt enters the T-shaped groove formed by the communication of the first transfer groove and the second transfer groove, after the T-bolt rotates a preset angle, since the groove width of the limiting end is smaller than that of the movable end, the limiting end limits the head of the T-bolt, so that the T-bolt can only be taken out along the length direction of the first transfer groove. During the transfer process, as long as the transfer device blocks the movable end, the T-bolt cannot be taken out from the transfer main body, which greatly improves the reliability during the transfer of the T-bolt. Through the cooperation of the first transfer groove, the second transfer groove, the limiting end and the movable end, making full use of the structural characteristics of the T-bolt, the self-limitation of the T-bolt is realized, so that the T-bolt can be directly transferred and taken. In addition, structures such as spring washers, washers and nuts can be assembled on the T-bolt to realize the transfer of the overall pre-assembled backing plate fastener, which is flexible and convenient. At the same time, the fixation of the T-bolt mainly depends on the head length. Therefore, on the premise of ensuring that the head length of the T-bolt is smaller than the groove width of the movable end, the groove width of the first transfer groove can be increased to accommodate more specifications and models of T-bolts, expanding the scope of application. When taking out the T-bolt, the T-bolt can be rotated back to be taken out through the second transfer groove, or the T-bolt can be directly taken out along the length direction of the first transfer groove. The taking efficiency is improved through multiple taking methods. Compared with the prior art, it has good flexibility, wide scope of application, good reliability and high taking efficiency, and is suitable for wide promotion and application.

[0027] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0028] Figure 1 It is a schematic structural diagram of the self-limiting backing plate fastener tray during application according to the preferred embodiment of the present utility model; Figure 2 It is a schematic structural diagram of the self-limiting backing plate fastener tray according to the preferred embodiment of the present utility model; Figure 3 It is a schematic structural diagram of the first perspective of the self-limiting backing plate fastener tray according to the preferred embodiment of the present utility model; Figure 4 It is a schematic structural diagram of the second perspective of the self-limiting backing plate fastener tray according to the preferred embodiment of the present utility model.

[0029] As Figures 1-4 As shown, the self-limiting backing plate fastener tray of this embodiment is used to transfer backing plate fasteners. The backing plate fasteners include T-shaped bolts. The tray includes a transfer main body 100, a first transfer groove 200 opened in the transfer main body 100 for accommodating the head of the T-shaped bolt, and a second transfer groove 300 opened on the transfer main body 100 and penetrating the transfer main body 100 for accommodating the shank of the T-shaped bolt. The first transfer groove 200 and the second transfer groove 300 communicate with each other and are arranged in a T shape. The groove width of the first transfer groove 200 is greater than the groove width of the second transfer groove 300. The first transfer groove 200 is provided with a limiting end 210 for limiting the head of the T-shaped bolt after rotating a preset angle and a movable end 220 for taking out the T-shaped bolt along the length direction of the first transfer groove 200. The groove width of the limiting end 210 is less than the groove width of the movable end 220.

[0030] As Figures 1-4As shown, specifically, for the self-limiting spacer fastener tray of the present utility model, the head of the T-bolt is accommodated in the first transfer groove 200 opened in the transfer main body 100. The head of the T-bolt is accommodated in the first transfer groove 200 that is opened on the transfer main body 100 and penetrates the transfer main body 100. And after the T-bolt enters the T-shaped groove formed by the communication of the first transfer groove 200 and the second transfer groove 300, after the T-bolt rotates a preset angle, since the groove width of the limiting end 210 is smaller than the groove width of the movable end 220, the limiting end 210 limits the head of the T-bolt, so that the T-bolt can only be taken out along the length direction of the first transfer groove 200. During the transfer process, as long as the transfer device blocks the movable end 220, the T-bolt cannot be taken out from the transfer main body 100, which greatly improves the reliability during the transfer of the T-bolt. Through the cooperation of the first transfer groove 200, the second transfer groove 300, the limiting end 210 and the movable end 220, making full use of the structural characteristics of the T-bolt, self-limitation of the T-bolt is realized, so that the T-bolt can be directly transferred and taken. In addition, structures such as spring washers, washers and nuts can be assembled on the T-bolt to realize the transfer of the overall pre-assembled spacer fastener, which is flexible and convenient. At the same time, the fixation of the T-bolt mainly depends on the head length. Therefore, on the premise of ensuring that the head length of the T-bolt is smaller than the groove width of the movable end 220, the groove width of the first transfer groove 200 can be increased to accommodate more specifications and models of T-bolts, expanding the scope of application. When taking out the T-bolt, the T-bolt can be rotated back to be taken out through the second transfer groove 300, or the T-bolt can be directly taken out along the length direction of the first transfer groove 200. The taking efficiency is improved through multiple taking methods. Compared with the prior art, it has good flexibility, wide application range, good reliability and high taking efficiency, and is suitable for wide promotion and application. It should be understood that the self-limiting spacer fastener tray of this embodiment can realize self-limiting transfer of T-bolts with a rod body diameter smaller than the groove width of the second transfer groove 300, and at the same time, the head length is greater than the groove width of the limiting end 210 and smaller than the groove width of the movable end 220. Since the head length of the T-bolt is often much larger than the rod body diameter, therefore, by increasing the groove width of the second transfer groove 300 and the groove width of the movable end 220, self-limiting transfer of more specifications and models of T-bolts can be realized. Preferably, the preset angle is 90°. At this angle, it can be ensured that the length direction of the head of the T-bolt is parallel to the width direction of the limiting end 210. It should be understood that the first transfer groove 200 and the second transfer groove 300 can accommodate multiple T-bolts along the length direction at the same time.

[0031] As Figure 1 and Figure 2As shown, in this embodiment, there are multiple first transfer grooves 200, and the multiple first transfer grooves 200 are arranged at intervals within the transfer main body 100, and the first transfer grooves 200 and the second transfer grooves 300 are arranged in one-to-one correspondence. Specifically, by respectively accommodating the heads of multiple T-bolts through the multiple first transfer grooves 200, and then arranging the first transfer grooves 200 and the second transfer grooves 300 in one-to-one correspondence, so as to respectively accommodate the rod bodies of the corresponding T-bolts through the multiple second transfer grooves 300, the transfer volume of the pallet is greatly increased, and the transfer efficiency is improved.

[0032] As Figure 1 and Figure 2 shown, in this embodiment, a hollow groove 400 is formed on the transfer main body 100, and the hollow groove 400 and the multiple first transfer grooves 200 are arranged in a staggered manner. Specifically, the weight of the transfer main body 100 is effectively reduced through the hollow groove 400, the transfer difficulty is reduced, and at the same time, it is convenient for handling and use, so as to improve the taking efficiency.

[0033] As Figure 1 and Figure 2 shown, in this embodiment, the hollow groove 400 is arranged between two adjacent first transfer grooves 200, and limiting grooves communicating with the adjacent first transfer grooves 200 are formed on both side walls of the hollow groove 400. The limiting grooves are used to enable the head of the T-bolt to enter the adjacent first transfer groove 200 after the T-bolt is accommodated in the hollow groove 400, so as to limit the T-bolt in the first transfer groove 200. Specifically, by arranging the hollow groove 400 between two adjacent first transfer grooves 200, and limiting grooves communicating with the adjacent first transfer grooves 200 are formed on both side walls of the hollow groove 400, the T-bolt can be accommodated through the hollow groove 400, and the head of the T-bolt in the hollow groove 400 can enter the adjacent first transfer groove 200, so as to self-limit the T-bolt in the hollow groove 400, and the hollow groove 400 can also be adapted to more specifications and models of T-bolts, expanding the scope of application.

[0034] As Figure 1 and Figure 2 shown, in this embodiment, there are multiple hollow grooves 400, and the multiple hollow grooves 400 are arranged at intervals on the transfer main body 100. Specifically, the weight of the transfer main body 100 is further reduced through the multiple hollow grooves 400, the transfer difficulty is reduced, and at the same time, it is convenient for handling and use, so as to improve the taking efficiency.

[0035] In this embodiment, the slot widths of the multiple hollow slots 400 are different. Specifically, the multiple hollow slots 400 with different slot widths are respectively used to accommodate T-shaped bolts with similar shank diameters, so as to improve the reliability during the transportation process while expanding the applicable range. It should be understood that the closer the shank diameter of the T-shaped bolt is to the slot width of the hollow slot 400, the smaller the moving space of the T-shaped bolt after the hollow slot 400 accommodates the T-shaped bolt, and the more stable and reliable the transportation process is. Optionally, in one embodiment, the slot widths of the multiple hollow slots 400 are the same.

[0036] In this embodiment, the tray includes multiple transfer bodies 100 stacked vertically. Specifically, by stacking the multiple transfer bodies 100 vertically, the transfer capacity of the tray is further improved, thereby enhancing the transfer efficiency.

[0037] As Figure 3 and Figure 4 shown, in this embodiment, stacking bosses 500 corresponding to the hollow slots 400 of the adjacent transfer bodies 100 are arranged on the bottom of the transfer body 100. The lower end of the stacking boss 500 is obliquely arranged and is used to partially embed into the hollow slot 400. The adjacent two transfer bodies 100 are stacked through the stacking bosses 500. Specifically, when the adjacent two transfer bodies 100 are stacked through the stacking bosses 500, a handling space is left between the adjacent two transfer bodies 100 for easy handling and taking, and the lower end of the stacking boss 500 is partially embedded into the hollow slot 400 of the adjacent transfer body 100 to achieve self-fitting and fastening, improving the stability after stacking. Optionally, the lower end of the stacking boss 500 is obliquely arranged downward and inward in the vertical direction to be arranged with a narrower bottom and a wider top, so as to be partially embedded into the hollow slot 400.

[0038] As Figure 3 and Figure 4 shown, in this embodiment, there are multiple stacking bosses 500, and the multiple stacking bosses 500 are arranged in a square array on the bottom of the transfer body 100. Specifically, by respectively partially embedding the multiple stacking bosses 500 into the corresponding hollow slots 400, self-fitting and fastening are achieved, further improving the stability of the transfer body 100 after stacking. At the same time, the multiple stacking bosses 500 are arranged in a square array with a reasonable layout and high structural reliability.

[0039] In this embodiment, the connection between the first transfer groove 200 and the second transfer groove 300 is chamfered. Specifically, the connection between the first transfer groove 200 and the second transfer groove 300 is chamfered to buffer and avoid the rotation self-limitation of the T-shaped bolt after the first transfer groove 200 and the second transfer groove 300 accommodate the T-shaped bolt, and prevent mutual collision and wear.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
