Description

Technical Field

[0001] The utility model relates to the technical field of railway detection, in particular to a grounding wire hook. Background Art

[0002] Rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and vehicles forward, bear the huge pressure of the wheels, and transmit it to the sleepers. Rails must provide a continuous, smooth and least resistant rolling surface for the wheels. In electrified railways or automatic block sections, rails can also serve as track circuits.

[0003] At present, the grounding wire hook structure used in the short-circuit construction and power supply maintenance of railway engineering is composed of (such as Figure 6 As shown in the figure, it consists of 1 with threaded hook, 2 buckle (with terminal), 3 gasket, 4 spring washer and 5 nut. When using, first hook the rail through the bottom of the rail, then put on parts 2, 3 and 4 in sequence, tighten the nut manually, and finally tighten the nut with a wrench. After the inspection, disassemble the short-circuit hook, which takes a lot of time and effort. For this reason, we propose a grounding hook. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a grounding wire hook, which solves the technical problem that the existing grounding wire hook used for power supply maintenance is complicated to install during use.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The grounding wire hook includes a hook and a buckle that can slide on the hook. The relative movement of the two realizes the clamping and releasing of the rail. The hook includes two parts, one part is the hook and the other part is the hook handle connected to the hook. The two are formed in one piece. The buckle is installed on the hook handle of the hook. At the same time, the protrusion on the buckle is opposite to the opening of the hook, which is used to clamp the rail.

[0009] In order to make the hook and the buckle close to each other, that is, to automatically clamp them on the rail, a traction structure is connected to the back of the hook and the buckle. The traction structure can be a spring, a hydraulic rod, etc., and any structure with resilience after the rope is pulled. In order to maintain the stability of the structure, the present application preferably uses a hydraulic rod, so that when the hook and the buckle are separated from each other, the buckle can be pulled in the direction of the hook.

[0010] Preferably, an inclined protrusion is provided on the outside of the buckle, and the protrusion is opposite to the hook.

[0011] Preferably, the traction structure can be a traction rod, and both ends of the traction rod are respectively hinged to a hook and a buckle; when the hook and the buckle are separated from each other, the pulling force of the traction rod on the buckle is directed towards the direction where the hook is located.

[0012] Preferably, handles are symmetrically arranged on both sides of the buckle, and the handles are hinged to the outer wall of the buckle. During use, simply rotate the handles outwards to unfold them. In order to limit the unfolding range of the handles and connect the handles to the buckle, a "C"-shaped bracket is connected to each side of the buckle. When the handles are unfolded, the rotating shafts at the ends of the handles fit with the inside of the brackets, preventing the handles from continuing to unfold.

[0013] Preferably, a threaded post is provided at the top of the buckle, and the buckle is externally connected to a wire through the threaded post, thereby connecting to the detection device.

[0014] (III) Beneficial effects

[0015] Due to the adoption of the socketing method, the hook and the buckle can move relative to each other, and then the traction rod provides a pulling force for the hook and the buckle to move towards each other. Secondly, a foldable handle is hinged outside the buckle, which is convenient for the user to manually stretch. Therefore, the technical problem of the cumbersome installation of the existing grounding wire hook used for power supply maintenance during use is effectively solved, and thus the installation and disassembly time is shortened, the tools carried are reduced, the working intensity of workers is alleviated, and the work efficiency is improved.

[0024] The embodiment of the present application provides a grounding wire hook, which effectively solves the technical problem of complicated installation of the existing grounding wire hook used for power supply maintenance. Due to the use of a sleeve connection method, the hook and the buckle can move relative to each other, and the traction rod provides the hook and the buckle with a pulling force to move towards each other. Secondly, a foldable handle is hinged on the outside of the buckle to facilitate manual stretching by the user, thereby shortening the installation and disassembly time, reducing the tools to be carried, reducing the work intensity of workers, and improving work efficiency.

[0025] Example

[0026] The technical solution in the embodiment of the present application effectively solves the technical problem that the existing grounding wire hook used for power supply maintenance is complicated to install when in use. The overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a grounding wire hook, which includes a hook 1 and a buckle 2 that can slide on the hook 1, and the relative movement of the two can realize the clamping and release of the rail. Figure 3 As shown, the hook 1 includes two parts, one part is the hook, and the other part is the hook handle connected to the hook, the two are integrally formed, and the buckle 2 is installed on the hook handle of the hook 1, as shown in FIG. Figure 1 As shown, at the same time, the protrusion on the buckle 2 is opposite to the opening of the hook, which is used to clamp the rail;

[0028] In order to make the hook 1 and the buckle 2 close to each other, that is, to automatically clamp them on the rail, a traction structure is connected to the back of the hook 1 and the buckle 2. The traction structure can be a spring, a hydraulic rod, etc., and any structure with resilience after stretching is acceptable. In order to maintain the stability of the structure, the present application takes the hydraulic rod as an example, so that when the hook 1 and the buckle 2 are separated from each other, the buckle 2 can be pulled in the direction of the hook.

[0029] In some examples, the traction structure may use a traction rod 6 (i.e., a hydraulic rod), and the two ends of the traction rod 6 are respectively hinged to the hook 1 and the buckle 2; when the hook and the buckle 2 are separated from each other, the pulling force of the traction rod 6 on the buckle 2 is in the direction of the hook.

[0030] In some examples, handles 4 are symmetrically arranged on both sides of the buckle 2, and the handles 4 are hinged to the outer wall of the buckle 2. When in use, just rotate the handle 4 outwards to unfold the handle 4. In order to limit the unfolding range of the handle 4 and connect the handle 4 to the buckle 2, a "C"-shaped bracket 3 is connected to each side of the buckle 2. When the handle is unfolded, the rotating shaft at the end of the handle 4 fits with the inside of the bracket 3, so that the handle 4 cannot continue to unfold, as Figure 2 shown.

[0031] In some examples, a threaded post 7 is provided at the top of the buckle 2, and the buckle 2 is externally connected to a wire through the threaded post 7, so as to be connected to the detection device.

[0032] When installing the device, first pass the hook 1 through the hole of the buckle 2, then install the hydraulic rod, pass through the bolt for fixation, and then install the two handles 4 on the brackets 3 respectively (the brackets 3 are welded to the buckle 2 in advance). The two handles 4 can rotate within a range of 90°, which is convenient for storage and carrying.

[0033] When using the device, polish the contact part of the buckle 4 to be contacted to ensure good contact between the buckle 2 and the steel rail. Hook the steel rail under the steel rail as Figure 2 shown, open the two folding handles 4, pull the handles 4 apart with both hands about 4 cm and then lift them up, as Figure 3 shown, and then release both hands. At this time, the buckle 2 exerts a pressure of about 20 - 30 kg on the buckle under the resilience of the hydraulic rod. According to the mechanical principle, the inclined plane of the buckle generates a pressure of about 40 - 60 kg on the steel rail, which can ensure good contact between the buckle 2 and the steel rail. Disassemble after maintenance is completed.

[0034] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
