Description

Technical Field

[0001] This utility model relates to the field of maintenance technology, specifically to a maintenance auxiliary tool. Background Technology

[0002] During the maintenance of large heat exchangers in chemical plants, the tube bundles often sag due to their own weight during installation. Adjustments to the tube sheet and end cap sealing surfaces are necessary. If there is ample space and an open area, lifting lugs are welded directly above the tube sheet, and a crane is used to pull the tube bundle upwards. The tube sheet is then manually adjusted to the appropriate position. If the space is limited and a crane cannot be used, a large-tonnage hand-operated hoist is used to pull the tube bundle upwards, and the tube sheet is then manually adjusted. The current problems with this technology are: heat exchanger tube bundle installation requires a large number of maintenance personnel, wasting manpower; using a crane is expensive and poses significant safety risks; welding lifting lugs to the tube sheet poses a high safety risk, increasing the risk of fire and explosion; using hand-operated hoists is strenuous and time-consuming; and the low efficiency and long maintenance time result in unfinished production tasks.

[0003] To solve the above problems, there is an urgent need for a maintenance auxiliary tool that can save manpower, material resources and financial resources in production, improve maintenance efficiency, enable heat exchangers to be put into use quickly, increase economic benefits and reduce the frequency of special operations. Summary of the Invention

[0004] A maintenance auxiliary tool that saves manpower, material resources and financial resources in production, improves maintenance efficiency, enables heat exchangers to be put into use quickly, increases economic benefits, and reduces the frequency of special operations.

[0005] A maintenance auxiliary tool includes a support rod connector, wherein:

[0006] The support rod connector has a support rod connection hole in the middle, and one end of the support rod is sleeved in the support rod connection hole. The support rod connector has a first correction screw hole and a second correction screw hole symmetrically arranged on the left and right sides. One end of the first correction screw is sleeved in the first correction screw hole, and one end of the second correction screw is sleeved in the second correction screw hole. A support rod rotation handle is provided on one side of both the first correction screw and the second correction screw.

[0007] Preferably, the support rod connector includes a connecting housing, the connecting housing having a through support rod connecting hole at its center, a pair of sliding rails symmetrically arranged on both sides inside the connecting housing, a set of limiting blocks at both ends of the sliding rails, a sliding rod mounted on the sliding rails, a connecting block at one end of the sliding rod, and a baffle at the other end of the sliding rod.

[0008] Preferably, two connecting blocks are provided, and the two connecting blocks are respectively provided with a first correction screw hole and a second correction screw hole.

[0009] Preferably, the first correction screw, the second correction screw, and the support rod are all provided with threads.

[0010] Preferably, one end of the support rod is detachably fitted with a reinforcing nut.

[0011] Preferably, the support rod rotating handle is provided with an anti-slip rubber pad.

[0012] Preferably, the top of the baffle is provided with an anti-collision rubber ring.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a maintenance auxiliary tool. The support rod connector of this tool adopts a symmetrical design and is stabilized by a first and a second adjusting screw, achieving good balance. This stability during construction reduces tool displacement caused by gravity or external forces during equipment maintenance, avoiding safety hazards. The sliding track and slide bar structure in the design allow the tool's length and angle to be freely adjusted according to usage needs. This flexibility enhances the tool's applicability. The rotating handle of the support rod is equipped with an anti-slip pad, which effectively reduces accidental slippage during use and helps improve operator safety. Simultaneously, the anti-collision rubber ring on the baffle effectively prevents damage to the equipment during operation, further enhancing safety. The rotating handle of the support rod is ergonomically designed, making it easier to operate and adjust, reducing the operational difficulty of traditional tools during adjustment, and improving maintenance efficiency. Furthermore, the use of a threaded adjusting screw makes adjustment and fixing simpler, requiring no additional tools. This tool can be used in various equipment maintenance and debugging situations, thus significantly increasing its overall application value. This tool provides an efficient, stable, and flexible maintenance tool that can significantly reduce equipment failure maintenance time, thereby reducing downtime losses caused by equipment failures and improving overall economic efficiency.

[0024] like Figure 1-7 As shown in this embodiment Figure 1-7 This utility model provides a maintenance auxiliary tool, including a support rod connector 1, wherein:

[0025] The support rod connector 1 has a support rod connection hole 101 in the middle. One end of the support rod 2 is fitted into the support rod connection hole 101. The support rod connector 1 has a first correction screw hole 102 and a second correction screw hole 103 symmetrically arranged on the left and right sides. One end of the first correction screw 3 is fitted into the first correction screw hole 102, and one end of the second correction screw 4 is fitted into the second correction screw hole 103. A support rod rotating handle 5 is provided on one side of both the first correction screw 3 and the second correction screw 4.

[0026] The support rod connector 1 includes a connecting housing 104. The connecting housing 104 has a through support rod connecting hole 101 at its center. A pair of sliding rails 105 are symmetrically arranged on both sides inside the connecting housing 104. A set of limiting blocks 106 are provided at both ends of the sliding rails 105. A slide rod 107 is mounted on the sliding rails 105. A connecting block 108 is provided at one end of the slide rod 107, and a baffle 109 is provided at the other end of the slide rod 107.

[0027] The number of connecting blocks 108 is two, and the two connecting blocks 108 are respectively provided with a first correction screw hole 102 and a second correction screw hole 103.
