Description

Technical Field

[0001] This utility model belongs to the field of lifting and hoisting, and specifically relates to a quick-release and convenient rail hoisting clamp. Background Technology

[0002] With the development of infrastructure and lifting equipment, the use of rail-mounted lifting equipment such as gantry cranes and bridge cranes is increasing. This is not only because the technology is mature, but also because the operating cost is much lower than other equipment. However, during the installation and dismantling of the rails, the process requires that the rails be hoisted one by one. The common method for hoisting rails is to use a pry bar to raise one end of the rail, then insert a steel wire rope to lift it. After the other end is off the ground, a wooden block is inserted. After lowering it, steel wire ropes are inserted into both ends at the same time and then it is lifted to the designated position. The same applies when dismantling the rails. After removing the rail pressure plate, it is also necessary to pry it open little by little and insert steel wire ropes in several times.

[0003] To solve the above problems, it is urgent to modify the scrap steel plates to create a quick-release and convenient rail hoisting clamp based on the existing materials at the construction site. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a quick-release and convenient rail hoisting clamp, which has a simple structure, is easy to operate and use, and greatly speeds up the installation and dismantling of rails and increases safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A quick-release and convenient rail hoisting clamp includes a clamp body with lifting lug holes and a rail insertion groove. The rail insertion groove is used to insert the rail, and the shape of the rail insertion groove is adapted to the cross-section of the rail. The rail insertion groove is provided with an anti-slip structure.

[0006] Preferably, the rail mounting groove has a T-shaped structure, and the size of the rail mounting groove is slightly larger than the cross-section of the rail.

[0007] Preferably, the anti-slip structure is an anti-slip layer connected to the rail mounting groove, and the anti-slip layer is used for contact with the lower end face of the rail.

[0008] Preferably, the lifting lug hole is located above the rail mounting slot.

[0009] Preferably, the fixture body is formed as a whole from Q235 or higher grade sheet metal, without welds or assembly.

[0010] Preferably, the anti-slip structure is a serrated groove, and the anti-slip structure is subjected to oil immersion quenching treatment.

[0011] Preferably, the clamp body has a square structure and all corners are rounded; the gap between the rail mounting groove and the outer contour of the rail is 2-3mm.

[0012] The present invention can achieve the following beneficial effects: This invention can effectively and quickly clamp and lift the track. Due to the presence of the anti-slip structure, it provides excellent anti-slip performance during the lifting process, thus increasing the safety factor. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a three-dimensional structural diagram of the present invention; Figure 2 This is a diagram illustrating the effect of using this utility model.

[0014] In the diagram: 1. Clamp body; 2. Lifting lug hole; 3. Rail mounting groove; 4. Anti-slip structure. Detailed Implementation

[0015] Preferred solutions include Figures 1 to 2 As shown, a quick-release and convenient rail hoisting clamp includes a clamp body 1, which has a lifting lug hole 2 and a rail insertion groove 3. The rail insertion groove 3 is used to insert the rail, and the shape of the rail insertion groove 3 is adapted to the cross section of the rail. The rail insertion groove 3 is provided with an anti-slip structure.

[0016] The anti-slip structure primarily serves to increase friction. Specifically, it can be a one-piece molded anti-slip structure, or a welded or other connected anti-slip layer. In this embodiment, the rail insertion groove 3 is a T-shaped structure, and its size is slightly larger than the cross-section of the rail. The lifting lug hole 2 is located above the rail insertion groove 3. The clamp body 1 is integrally formed from 20mm thick Q235 or higher grade sheet metal, without welds or assembly. The lifting lug hole 2 is located at the top of the clamp, and the corner of this hole is rounded to ensure that there are no sharp edges that could damage the shackle. The anti-slip structure at the contact point between the clamp body 1 and the rail is a serrated groove. This part is treated with oil immersion quenching, resulting in high hardness and resistance to wear. The inner contour of the clamp body 1 is similar to the outer contour of the rail, and there is only a 2-3mm gap between the two sides and the rail when they are fitted. All corners of the clamp body 1 are rounded to facilitate easy insertion into the rail during fitting.

[0017] The working principle of this device is as follows: like Figure 1-2 As shown, before use, insert the shackle on the wire rope into the lifting lug hole, and then slide the clamp into one end of the rail. When using, two clamps are needed together, one at each end of the rail. After clamping in the correct position, you can start lifting and hoisting.

[0018] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
