Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly and assembly of large couplings, and in particular relates to a large coupling quick disassembly and assembly auxiliary device. Background Art

[0002] In the existing industrial production process, the installation and disassembly of large couplings usually requires a lot of manpower and time, and there are certain safety risks. Due to the heavy weight of large couplings, small equipment is needed to lift them during the disassembly process. After the coupling is lifted to the same height as the shaft, it can be installed. Since there is no special lifting equipment during lifting, accidents of couplings falling often occur, which not only causes damage to the coupling, but also may injure the staff, and requires multiple alignment adjustments, and even some auxiliary brackets need to be welded to maintain stability. The disassembly efficiency is low, and at least 5 people are required to operate. Therefore, it is necessary to develop an auxiliary device that can improve disassembly efficiency, reduce labor costs and ensure safety. Summary of the invention

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figure 1-2As shown, a large coupling quick disassembly and assembly auxiliary device includes a lifting forklift 1, a lifting end of the lifting forklift 1 is welded with a vertical plate 2, two support rods 3 are welded on the vertical plate 2, a support plate 4 is welded between the two support rods 3, the lifting forklift 1 is provided with two bottom supports 5 and two vertical supports 6, the bottom ends of the bottom supports 5 are each installed with a plurality of moving wheels 7, the vertical supports 6 are each plugged with two connecting rods 8, and both ends of the connecting rods 8 are threaded with nuts 10.

[0023] The support plate 4 is semicircular, and a gap is left between the towing rod and the vertical plate 2. Since the coupling 15 is generally provided with a flange, the cable can be placed in the gap, so that the coupling 15 is conveniently placed and the coupling 15 is prevented from tilting when placed on the support plate 4.

[0024] A handle 13 is welded on the upright support 6. The handle 13 is used to push the utility model to move.

[0025] Both ends of the connecting rod 8 are in the shape of external threads, and two nuts 10 are respectively threadedly connected to both ends of the connecting rod 8 in the shape of external threads.

[0026] The upper and lower ends of the side of the vertical support 6 are welded with ear plates 14, and the ear plates 14 are provided with strip holes 11, and the connecting rod 8 is inserted into the vertical support 6 through the strip holes 11. The strip holes 11 are used to adjust the height of the connecting rod 8. Since the heights of the lifting ears of each device and the welded channel steel 12 are different, the height of the connecting rod 8 can be adjusted by sliding the connecting rod 8 in the strip holes 11.

[0027] Two baffles 9 are sleeved on the connecting rod 8 inserted into the ear plate 14 above the vertical support 6 . The two baffles 9 are respectively located on both sides of the vertical support 6 and between the two nuts 10 .

[0028] The connecting rod 8 inserted into the ear plate 14 below the vertical support 6 is sleeved with a channel steel 12 and a baffle plate 9, which are respectively located on both sides of the vertical support 6 and between two nuts 10. Some equipment is not convenient to punch holes, otherwise it will cause damage to the equipment, so the channel steel 12 can be welded to fix the connecting rod 8. After the channel steel 12 is welded on the equipment and the disassembly and assembly of the coupling 15 is completed, it does not need to be cut off, and it can continue to be used during the defective disassembly and assembly.

[0029] The working principle of the utility model is:

[0030] When in use, the coupling 15 is placed on the support plate 4, the handle 13 is held and pushed to the shaft end of the device, the forklift 1 is lifted, the central axis of the coupling 15 is aligned with the central line of the shaft of the device, and the forklift 1 is pushed forward to fit the coupling 15. Since the connection between the coupling 15 and the shaft is an interference fit, it is impossible to directly sleeve it on the shaft, so the coupling 15 can be heated for 30 minutes in advance, and grease can be applied to the shaft, and the inner diameter of the coupling 15 can be slightly enlarged by using the principle of thermal expansion and contraction, but it is impossible to sleeve it on the shaft in one go even if it is heated.

[0031] At this time, the coupling 15 needs to be sleeved on the shaft with the help of external force. After passing the connecting rod 8 in the ear plate 14 at the upper end of the vertical support 6 through the lifting ear of the equipment, the baffle 9 is sleeved and the nut 10 is screwed on, and the channel steel 12 is welded to the equipment shell, and then the connecting rod 8 in the ear plate 14 at the lower end of the vertical support 6 is passed through the channel steel 12 and the nut 10 is screwed on. Pay attention to the welding position of the channel steel 12 and the position of the connecting rod 8 in the strip hole 11, and try to make the connecting rod 8 in a horizontal state. In this way, the vertical plate 2 supports the coupling 15, and the connecting rod 8 pulls the four corners of the lifting forklift 1. Continuously tighten the nuts 10 located at the four corners of the lifting forklift 1 diagonally, so that the vertical plate 2 on the lifting forklift 1 continuously pushes the coupling 15 to sleeve the shaft of the equipment. During this period, the coupling 15 needs to be continuously flame-baked until the coupling 15 is in place. After the channel steel 12 is welded, it does not need to be welded again when the coupling 15 is disassembled and assembled next time, and it can be used directly.

[0032] When the coupling 15 is disassembled, there is no need to use a lifting device to suspend the coupling 15. It is only necessary to use the support plate 4 on the forklift to support the coupling 15 to prevent it from falling.

[0033] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0034] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
