Abstract
Description
Technical Field
[0001] This application relates to the field of electric hoist repair technology, and in particular to a structure for quick replacement of electric hoists. Background Technology
[0002] Electric hoists are a type of special equipment installed on overhead cranes and gantry cranes. They are characterized by their small size, simple operation, and ease of use, and are used in belt conveyor stations, factories, and other similar locations. Electric hoists travel along I-beam steel rails to lift and transport spare parts and equipment below the rails. When an electric hoist malfunctions and needs replacement, personnel must perform high-altitude operations to dismantle and replace the old hoist. Furthermore, the newly installed electric hoist requires adjusting the clearance between the inner edge of the traveling wheel flange and the flange of the I-beam steel rail. Maintenance work is time-consuming, labor-intensive, and involves working at height, posing significant safety hazards. Therefore, improvements are needed. Utility Model Content
[0003] To improve the convenience of replacing electric hoists, this application provides a structure for quick replacement of electric hoists.
[0004] The present application provides a quick-change electric hoist structure using the following technical solution: A structure for quick replacement of an electric hoist includes a temporary track and an electric hoist slidably mounted on the temporary track. The temporary track is hollow, forming a hollow section. A connecting rod is provided at one end of the temporary track. One end of the connecting rod is inserted into the hollow section, and a connecting hole is provided through the end of the connecting rod inserted into the hollow section. A connecting hole is provided on the inner wall of the hollow section corresponding to the connecting hole. A positioning bolt is provided on the temporary track. The positioning bolt passes through the connecting hole and the connecting hole in sequence to fix the connecting rod to the temporary track.
[0005] By adopting the above technical solution, the connecting rod is inserted into the hollow part for positioning and fixation, so that the temporary track and the connecting rod form a detachable docking structure. When the electric hoist needs to be replaced, the gap of this section of the tooling electric hoist is adjusted on the ground. After adjustment, it is lifted by a crane to the electric hoist crossbeam at the transfer station. The end cap of the crossbeam section is removed, and it is docked onto the electric hoist track and slowly moved horizontally. After the replacement is completed, only the positioning bolts need to be unscrewed to separate the temporary track from the connecting rod, and the electric hoist replacement operation can be carried out quickly. This greatly simplifies the disassembly and assembly process, shortens the equipment downtime, and effectively improves the continuity of production operations.
[0006] Preferably, in the trapezoidal structure of the docking rod, the side length of the end into which the docking rod is inserted is greater than the side length of the end extending out of the hollow part.
[0007] By adopting the above technical solution, the connecting rod using this structure forms a wedge-shaped fit with the electric hoist's crossbeam track, significantly enhancing the structural stability after connection and effectively avoiding misalignment during electric hoist replacement.
[0008] Preferably, the docking holes are provided in several groups at equal intervals on the docking rod, and the connecting holes are provided in several groups at equal intervals on the hollow part of the temporary track, with the docking holes and connecting holes distributed along the sliding direction of the electric hoist.
[0009] By adopting the above technical solution, different hole positions can be selected for matching according to the actual installation length requirements, so as to achieve flexible adjustment of the docking length and adapt to different installation spaces and operation requirements.
[0010] Preferably, the temporary track has an I-shaped structure.
[0011] By adopting the above technical solutions, the I-beam structure has excellent bending load-bearing capacity, which can effectively improve the load-bearing capacity of the temporary track for the electric hoist. At the same time, it forms a reliable lateral limit on the traveling section of the electric hoist, preventing the electric hoist from deviating during travel and ensuring operational stability.
[0012] Preferably, one end of the temporary track is provided with a plug, and one end of the plug is inserted into the hollow part.
[0013] By adopting the above technical solution, the installation of plugs on the temporary track can protect the structural safety of the hollow section.
[0014] Preferably, the outer diameter of the plug is larger than the outer diameter of the temporary track.
[0015] By adopting the above technical solution, it is possible to effectively prevent the plug from loosening and entering the hollow part, thus affecting the installation of the connecting rod.
[0016] Preferably, the bottom end of the electric hoist is provided with an adjustment component to simplify the angle adjustment process of the electric hoist.
[0017] Preferably, the adjustment component includes two sets of corner brackets and a traction chain fitted inside the corner brackets, with both sets of corner brackets fixed to the bottom of the electric hoist.
[0018] By adopting the above technical solution, the hoisting angle can be quickly adjusted based on the cooperation of the traction chain and the angle code, without the need to disassemble multiple sets of bolts. This simplifies the subsequent angle adjustment process of the electric hoist and improves the equipment's adaptability to different hoisting conditions.
[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. The connecting rod is inserted into the hollow part for positioning and fixation, so that the temporary track and the connecting rod form a detachable docking structure. When the electric hoist needs to be replaced, the gap of this section of the tooling electric hoist is adjusted on the ground. After adjustment, it is lifted by a truck crane to the electric hoist crossbeam at the transfer station. The end cap of the crossbeam section is removed, and it is docked onto the electric hoist track and slowly moved horizontally. After the replacement is completed, only the positioning bolts need to be unscrewed to separate the temporary track from the connecting rod, and the electric hoist replacement operation can be carried out quickly. This greatly simplifies the disassembly and assembly process, shortens the equipment downtime, and effectively improves the continuity of production operations. 2. The connecting rod of this application uses an I-beam structure, which forms a wedge fit with the crossbeam track of the electric hoist, significantly enhancing the structural stability after docking and effectively avoiding misalignment during the replacement of the electric hoist.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0026] This application discloses a structure for quickly replacing an electric hoist. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a temporary track 2 and an electric hoist 1 that is slidably mounted on the temporary track 2. In this embodiment, the temporary track 2 adopts an I-shaped structure, and the traveling section of the electric hoist 1 is slidably mounted on the temporary track 2. The I-shaped structure of the temporary track 2 gives it excellent bending resistance and can effectively improve the load-bearing capacity of the temporary track 2 on the electric hoist 1. At the same time, it forms a reliable lateral limit on the traveling section of the electric hoist 1 to prevent the electric hoist 1 from deviating during travel and ensure operational stability.
[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The temporary track 2 is hollow, forming a hollow section 24. A plug 22 is provided at one end of the hollow section 24, and one end of the plug 22 is inserted into the hollow section 24. The outer diameter of the plug 22 is larger than the outer diameter of the temporary track 2. A connecting rod 3 is provided at the other end of the temporary track 2, and one end of the connecting rod 3 is inserted into the hollow section 24. In this embodiment, the connecting rod 3 adopts a trapezoidal structure. The side length of the end of the connecting rod 3 outside the temporary track 2 is smaller than the side length of the end inside the hollow section 24, that is, it has a structure that is narrow at the front end and wide at the back end, so that the connecting rod 3 and the crossbeam track of the electric hoist 1 can form a wedge fit, which significantly enhances the structural stability after docking and effectively avoids the occurrence of inaccurate docking during the replacement of the electric hoist 1.
[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting rod 3 is inserted into the hollow part 24 at one end, through which a connecting hole 31 is formed. A connecting hole 23 is formed on the inner wall of the hollow part 24 corresponding to the connecting hole 31. A positioning bolt 21 is provided on the temporary track 2. The positioning bolt 21 passes through the connecting hole 23 and the connecting hole 31 in sequence to fix the connecting rod 3 to the temporary track 2. In this embodiment, several sets of connecting holes 31 are formed at equal intervals on the connecting rod 3, and several sets of connecting holes 23 are formed at equal intervals on the hollow part 24 of the temporary track 2. The several sets of connecting holes 31 and connecting holes 23 are distributed along the sliding direction of the electric hoist 1. Based on the above technical solution, different hole positions can be selected for matching according to the actual installation length requirements, so as to realize the flexible adjustment of the docking length and adapt to different installation spaces and operation requirements.
[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The bottom of the electric hoist 1 is equipped with an adjustment component 4 to simplify the angle adjustment process of the electric hoist 1. The adjustment component 4 includes two sets of angle brackets 41 and a traction chain 42 sleeved in the angle brackets 41. Both sets of angle brackets 41 are fixed to the bottom of the electric hoist 1. Based on the cooperation between the traction chain 42 and the angle brackets 41, the hoisting angle can be quickly adjusted without disassembling multiple sets of bolts, which simplifies the subsequent angle adjustment process of the electric hoist 1 and improves the equipment's adaptability to different hoisting conditions.
[0030] The implementation principle of the quick replacement structure of the electric hoist in this application embodiment is as follows: the connecting rod 3 is inserted into the hollow part 24 to achieve positioning and fixation, so that the temporary track 2 and the connecting rod 3 form a detachable connecting structure. When the electric hoist 1 needs to be replaced, the gap of this section of the tooling electric hoist 1 is adjusted on the ground. After adjustment, it is lifted by a crane to the crossbeam of the electric hoist 1 at the transfer station. The end cap 22 of the crossbeam section is removed, and it is connected to the track of the electric hoist 1 and slowly moved horizontally. After the replacement is completed, only the positioning bolt 21 needs to be unscrewed to separate the temporary track 2 from the connecting rod 3, and the replacement operation of the electric hoist 1 can be carried out quickly. This greatly simplifies the disassembly and assembly process, shortens the equipment downtime, and effectively improves the continuity of production operations.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
