Abstract
Description
Technical Field
[0001] The utility model relates to the field of component processing, in particular to a connecting bracket boring hanger tool. Background Art
[0002] Rail-mounted cranes are mobile slewing cranes that travel on tracks laid along the ground and need to be disassembled and reassembled when moving to a new work site. They include tower cranes and portal cranes. A rail-mounted crane is primarily composed of a hoisting mechanism, trolley mechanism, carriage mechanism, power house, and driver's cab.
[0003] At present, in the process of rail crane processing, when different components are installed, it is inevitable that connecting brackets will need to be used for installation or fixation. In the process of processing the connecting bracket, due to the large size and heavy weight of the connecting bracket, when using boring machines and other processing machines to bore the connecting bracket, it is often necessary to use a crane to load and unload the connecting bracket. In this process, the traditional lifting method is to directly bind the connecting bracket with a sling to achieve the lifting of the connecting bracket onto the machine. The lifting efficiency is low and there are great safety hazards. When the sling contacts the connecting bracket, relative sliding and friction are likely to occur, resulting in wear of the sling, and then breakage, causing the object to fall. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a connecting bracket boring hoist tool with high lifting efficiency and safety.
[0005] In order to solve the above technical problems, the technical solution of the utility model is: a connecting bracket boring hanger tool, the connecting bracket has a pre-machined prefabricated hole, and its innovation lies in: the hanger tool includes
[0006] A hanging shaft connected to the prefabricated hole, wherein the diameter of the hanging shaft is smaller than the diameter of the prefabricated hole, a limiting plate is provided on one side of the hanging shaft, and the size of the limiting plate is larger than the size of the prefabricated hole, an external thread structure is provided on the outer wall of the other side of the hanging shaft, and a limiting nut is also threadedly connected to the side of the hanging shaft, and the outer wall size of the limiting nut is larger than the size of the prefabricated hole;
[0007] A lifting ring is connected to the lifting shaft on one side of the limiting plate, and the lifting ring is hinged to the lifting shaft.
[0008] Furthermore, the connection between the lifting ring and the lifting shaft is: the lifting ring and the lifting shaft are connected by a pin shaft, the lifting ring is C-shaped or U-shaped, and a first through hole for the pin shaft to pass through is opened on both sides of the lifting ring, and a second through hole for the pin shaft to pass through is opened on the lifting shaft, and the hinge between the lifting ring and the lifting shaft is realized by the pin shaft passing through the first through hole and the second through hole.
[0009] Furthermore, one side of the pin shaft has an end structure, and the size of the end structure is larger than the size of the first through hole, and the other side of the pin shaft has a pier head structure, and the size of the pier head structure is larger than the size of the first through hole.
[0010] The advantages of the present invention are that: the tooling in the present invention, through the design of components such as the lifting shaft and the lifting ring, cooperates with the prefabricated holes on the connecting bracket, and utilizes the prefabricated holes on the connecting bracket to lift the connecting bracket, which makes lifting more convenient, and the lifting belt does not directly contact the connecting bracket, which also avoids the phenomenon of the lifting belt breaking due to friction between the connecting bracket and the connecting bracket, and the lifting is safer.
[0011] For the connection between the lifting ring and the lifting shaft, a pin shaft is used to achieve the articulation between the two, so that the lifting ring can rotate relative to the lifting shaft, making it convenient for the lifting ring and the lifting belt to cooperate to achieve lifting.
[0012] The design of the end structure and the pier head structure on both sides of the pin shaft is to limit the relative position between the pin shaft and the lifting ring after the pin shaft passes through the first through hole and the second through hole, so as to prevent the pin shaft from slipping out of the through hole, thereby causing the lifting ring to separate from the lifting shaft and affecting the smooth progress of the lifting. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic diagram of the connecting bracket boring hanger tooling of the present invention. DETAILED DESCRIPTION
[0014] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0015] like Figure 1 The connecting bracket has a prefabricated hole pre-machined on the connecting bracket. The sling tooling includes
[0016] The hanging shaft 1 is connected to the prefabricated hole. The hanging shaft 1 is a cylindrical structure, and the diameter of the hanging shaft 1 is smaller than the diameter of the prefabricated hole on the connecting bracket. One side of the hanging shaft 1 has a limit plate 2, which is ring-shaped, and the size of the limit plate 2 is larger than the size of the prefabricated hole on the connecting bracket. The outer wall of the other side of the hanging shaft 1 has an external thread structure, and a limit nut 3 is also threadedly connected to this side of the hanging shaft 1, and the size of the outer wall of the limit nut 3 is larger than the size of the prefabricated hole on the connecting bracket. This design makes it possible to use the limit plate 2 and the limit nut 3 to cooperate with each other to limit and fix the relative position of the hanging shaft 1 and the connecting bracket after the hanging shaft 1 passes through the prefabricated hole, thereby avoiding the phenomenon of separation between the hanging shaft 1 and the connecting bracket during the lifting process.
[0017] The lifting ring 4 is connected to the suspension shaft 1 on one side of the limit plate 2, and the lifting ring 4 is hinged to the suspension shaft 1. The connection between the lifting ring 4 and the suspension shaft 1 is as follows: the lifting ring 4 and the suspension shaft 1 are connected via a pin 5. The lifting ring 4 is C-shaped or U-shaped, and a first through hole for the pin 5 to pass through is provided on both sides of the lifting ring 4. A second through hole for the pin 5 to pass through is provided on the suspension shaft 1. The hinge between the lifting ring 4 and the suspension shaft 1 is achieved by passing the pin 5 through the first through hole and the second through hole. For the connection between the lifting ring 4 and the suspension shaft 1, the pin 5 is used to achieve the hinge between the two, so that the lifting ring 4 can rotate relative to the suspension shaft 1, which is convenient for the lifting ring 4 to cooperate with the sling to achieve lifting.
[0018] One side of the pin 5 has an end structure 51, and the size of the end structure 51 is larger than the size of the first through hole. The other side of the pin 5 has a pier structure 52, and the size of the pier structure 52 is larger than the size of the first through hole. The design of the end structure 51 and the pier structure 52 on both sides of the pin 5 is to limit the relative position between the pin 5 and the lifting ring 4 after the pin 5 passes through the first through hole and the second through hole, so as to prevent the pin 5 from slipping out of the first through hole and the second through hole, thereby causing the lifting ring 4 to separate from the hanging shaft 1 and affecting the smooth progress of the lifting. When fixing, first align the two first through holes of the lifting ring 4 with the second through hole of the hanging shaft 1, then pass one side of the pin 5 through the first through hole and the second through hole, and finally perform a pier treatment on one side of the pin 5, thereby completing the fixation between the pin 5 and the lifting ring 4 and the hanging shaft 1.
[0019] When using the tooling in the utility model to lift the connecting bracket, first, pass the side of the lifting shaft 1 with the external thread structure through the prefabricated hole on the connecting bracket, and after passing through, use the limit nut 3 to lock and fix the lifting shaft 1, and then fix the crane's sling and the lifting ring 4 to lift the connecting bracket. The tooling of the utility model uses the prefabricated hole on the connecting bracket to lift the connecting bracket, which makes lifting more convenient. The sling does not directly contact the connecting bracket, and the phenomenon of the sling breaking due to friction between the connecting bracket is avoided, making lifting safer.
