Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts detection, in particular to a spiral spike cold bending test tool. Background Art

[0002] Spiral spikes are used as railroad track accessories to tighten rails. Traditional spiral spikes are prone to deformation due to constant friction between the bearing surface under the head and the rail surface during use. These spikes can easily break after prolonged friction, causing the rails to loosen and posing a safety hazard. Frequent track repair and maintenance are required, leading to material waste and significantly increased manufacturing and subsequent maintenance costs. Therefore, to avoid frequent problems with spiral spikes, they must be tested using cold bending test equipment.

[0003] Existing technologies include a utility model with publication number CN220603137U, which discloses a spiral road spike cold bending test tool. The patent comprises a workbench and a column, wherein columns are provided on both sides of the top surface of the workbench, and a top plate is provided on the top of the column. A hydraulic cylinder is installed at a middle position of the top surface of the top plate, and the output end of the hydraulic cylinder passes through the top plate and is fixedly connected to a pressure head. The top surface of the workbench is provided with side plates on both sides of the column, and an electric telescopic rod is installed on one side surface of the side plate. The utility model solves the problem that the equipment uses a manual method to compress and fix the spiral road spike, which easily increases the labor intensity of the staff and is inconvenient to compress and fix the spiral road spike.

[0004] The inventors discovered in their daily work that during the use of the equipment, when the equipment was performing bending tests on objects, the objects were prone to sudden breakage, and the broken fragments could easily cause injuries to the operators. Utility Model Content

[0005] The utility model aims to solve the shortcoming in the prior art that broken fragments of an object may cause damage to a user, and proposes a spiral road spike cold bending test tool.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a spiral spike cold bending test tool, comprising a box body and a protective device, the upper surface of the box body is fixedly connected to a placement seat, the upper surface of the box body is fixedly connected to a slide rail, the upper surface of the placement seat is provided with a top plate, the upper surface of the top plate is fixedly connected to a cylinder, the protective device is arranged on the surface of the box body, the protective device comprises a protective door and a rotating block, the protective door is arranged on the surface of the box body, the rotating block is fixedly connected to the surface of the placement seat and the top plate, the protective door is rotatably connected to the surface of the rotating block, the surface of the protective door is fixedly connected to a connecting block, a pulling hole is opened inside the connecting block, a limiting groove is opened on the surface of the box body, and a limiting rod is slidably connected to the inside of the pulling hole.

[0007] Furthermore, one end of the limiting rod is engaged with the inner wall of the limiting groove, and a retaining ring is fixedly connected to the surface of the limiting rod. By setting the limiting rod, the protective door can be restricted, thereby reducing the risk of the protective door shaking randomly and being difficult to protect when the equipment is in use.

[0008] Furthermore, a first spring is fixedly connected to the surface of the retaining ring, and one end of the first spring away from the retaining ring is fixedly connected to the inner wall of the pulling hole. The first spring is provided to facilitate application of a reset elastic force to the retaining ring.

[0009] Furthermore, one end of the limiting rod is fixedly connected to a pull rod, and the pull rod is provided to facilitate the movement of the limiting rod.

[0010] Furthermore, an adjustment device is provided on the upper surface of the slide rail, and the adjustment device includes a placement block and an adjustment slot. The adjustment slot is provided with the surface of the slide rail, and the placement block is slidably connected to the inner wall of the slide rail. The side of the placement block is fixedly connected with a limiting block, and the inner wall of the limiting block is slidably connected with an adjustment rod. By setting the adjustment rod, the placement block can be restricted, thereby reducing the situation where the placement block is prone to sliding when the equipment is in use, making it difficult to place items.

[0011] Furthermore, a protrusion is fixedly connected to the side of the placement block, and one end of the adjustment rod is engaged with the inner wall of the adjustment groove. The protrusion is provided to facilitate limiting the second spring.

[0012] Furthermore, a second spring is fixedly connected to the surface of the adjusting rod, and one end of the second spring away from the adjusting rod is fixedly connected to the surface of the protrusion. The second spring is provided to facilitate applying a restoring elastic force to the adjusting rod.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] In the utility model, when the device is in use, the user places the articles that need to be put in and out on the surface of the placement block, and then starts the equipment cylinder to perform bending detection on the articles. When the device is in use, the user pulls the pull rod, and then the pull rod moves to drive the limit rod to move, and the movement of the limit rod drives the movement of the retaining ring, and the movement of the retaining ring drives the first spring to move and deform to generate elastic force, and then the limit rod moves out of the inside of the limit groove, and then the protective door loses its restraint. By setting up the protective device, the user is effectively protected, and it plays a role in protecting the operator, reducing the risk of sudden breakage of the article when the device is in use and performing bending detection on the article, and the broken fragments are likely to cause injury to the operator, thereby improving the practicality of the device.

[0015] In the utility model, by providing an adjustment device, when using the device, the user pulls the adjustment rod, and when the adjustment rod moves, the second spring is driven to be displaced and deformed to generate elastic force, and the adjustment rod is then moved out of the inside of the adjustment slot, and the placement block is then freed from restraint. By providing the adjustment device, the placement block is effectively adjusted, which plays the role of adjusting the placement block, reduces the situation where the placement block is difficult to adjust when the device is in use, causing the placement block to be difficult to place items of different lengths, and improves the practicality of the device.
