Description

Technical Field

[0001] The utility model relates to the technical field of rail splint lifting tools, in particular to a rail splint lifting tooling. Background Technique

[0002] A rail splint (also known as a fishplate or track splint), is a connecting fastener used for connecting between rails and plays a connecting role at the rail joint. When moving a batch of splints, a lifting device is needed, usually a gantry crane. Generally, steel ropes or rods are used to string multiple splints together, and then the hook of the gantry crane is connected to the strung splints to complete the batch lifting of the splints.

[0003] At present, most splint manufacturers do not have a special and suitable batch lifting tooling for splints. Using steel ropes or rods to string the splints is very laborious and time-consuming. Not only is the stringing efficiency low, but the stringing quantity is also low. Content of the Utility Model

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A rail splint lifting tooling includes a bottom plate, side plates, laminates, string rods, plugs and lifting rings. The side plates are installed on the bottom plate. A plurality of the laminates are arranged in parallel and vertically installed on the sides of the side plates. Accommodating cavities are formed between the bottom plate and the laminates and between the laminates and the laminates. The string rods are located therebetween and are threadedly connected to the side plates. The plugs are threadedly installed at the outer ends of the string rods. Four lifting rings are installed on the sides of the bottom plate.

[0007] A further technical solution is that the accommodating cavity is inclined downward, and the lower end of the accommodating cavity is close to the side plate.

[0008] A further technical solution is that a through hole is provided at the outer end of the string rod, and a crowbar adapted to it is provided in the through hole.

[0009] A further technical solution is that a top ring is provided on the side of the plug.

[0010] A further technical solution is that a strip-shaped groove is provided on the bottom plate, a connecting rod is slidably installed in the strip-shaped groove, both ends of the connecting rod are threadedly connected to two of the lifting rings respectively, and locking nuts are symmetrically provided and threadedly installed on the connecting rod, and the locking nuts are located between the lifting rings and the bottom plate.

[0011] A further technical solution is that the diameter of the string rod is not greater than the aperture diameter of the clamping plate.

[0012] Compared with the prior art, at least one of the following beneficial effects can be achieved by the present utility model:

[0013] The present utility model provides a lifting tool for rail clamping plates. This tool can string and lift a large number of clamping plates at one time. The clamping plates are layered and do not interfere with each other. Moreover, when it is necessary to unload the clamping plates, the string rod can be directly disassembled, and the clamping plates can be pulled out from any one of the two sides of the tool, which is convenient to operate, time-saving and labor-saving. With the mutual cooperation of the side plates, layer plates, string rods and plugs, the stability of the clamping plate stringing and lifting process is greatly improved.

[0024] Embodiment 1:

[0025] As shown in this embodiment Figure 1 A rail splint lifting tooling includes a bottom plate 1, side plates 2, laminates 3, string rods 4, plugs 5 and lifting rings 6. The side plates 2 are installed on the bottom plate 1. A plurality of laminates 3 are arranged in parallel and vertically installed on the sides of the side plates 2. Accommodation cavities 7 are formed between the bottom plate 1 and the laminates 3 and between the laminates 3. The string rods 4 are located therebetween and are threadedly connected to the side plates 2. The plugs 5 are threadedly installed on the outer ends of the string rods 4. Four lifting rings 6 are installed on the sides of the bottom plate 1.

[0026] The splints 14 are installed on the tooling in a certain order, generally from bottom to top, and the holes on the splints 14 are aligned with the string rods 4, and then pushed into the accommodating chambers 7 one by one. After the lower accommodating chamber 7 is installed, the plugs 5 are threadedly installed on the string rods 4 and the splints 14 are pressed tightly to prevent the splints 14 from moving back and forth. Then start loading the upper layer, following the same operation until all the accommodating chambers 7 are filled, or all the splints 14 are installed. Finally, with the help of steel ropes, the lifting rings 6 are connected to the hooks of the overhead crane for lifting.

[0027] Preferably, the accommodating cavity 7 is arranged to be inclined downward, and the lower end of the accommodating cavity 7 is close to the side plate 2 .

[0028] The accommodating cavity 7 is tilted downward, which can facilitate the stringing of the clamping plate 14 on the string rod 4.

[0029] Preferably, a through hole 8 is provided at the outer end of the string rod 4, and a pry bar 9 adapted thereto is provided in the through hole 8.

[0030] When the clamping plate 14 needs to be removed from the tooling, the string rod 4 can be rotated with the help of the pry bar 9 to remove the string rod 4 from the side plate 2. At this time, the clamping plate 14 can be pulled out from any side of the two sides of the tooling.

[0031] Preferably, a top ring 10 is provided on the side of the plug 5 .

[0032] The side of the clamping plate 14 generally has a depression, and the top ring 10 can support the depression, pressing against the clamping plate 14 while preventing the plug 5 from being too close to the clamping plate 14, making it difficult to remove the plug 5.

[0033] Embodiment 2:

[0034] Based on the above embodiment, this embodiment Figure 2 and Figure 3 As shown, a strip groove 11 is provided on the base plate 1, and a connecting rod 12 is slidably installed in the strip groove 11. The two ends of the connecting rod 12 are threadedly connected to two lifting rings 6 respectively. A locking nut 13 is symmetrically arranged and threadedly installed on the connecting rod 12, and the locking nut 13 is located between the lifting ring 6 and the base plate 1.

[0035] Depending on the specifications of the splint 14 and the loading conditions of the tooling, the center of gravity of the tooling will change. The position of the connecting rod 12 in the strip groove 11 can be adjusted back and forth to adapt to the change in center of gravity to ensure smooth lifting work. At the same time, when subsequently lifting the same type of splints 14, try to use the same loading scale.

[0036] Preferably, the diameter of the string rod 4 is not larger than the hole diameter of the clamping plate 14 .

[0037] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
