[0002] Lifting devices for fire equipment maintenance are commonly used for the inspection, replacement, and maintenance of high-altitude equipment such as fire pipelines, sprinkler heads, and fire extinguishers. Their function is to safely and efficiently transport maintenance personnel and tools to designated heights, overcoming the difficulties of working at heights. At the same time, they can carry testing instruments to accurately locate equipment faults, ensuring operational stability and safety, greatly improving the efficiency and quality of fire equipment maintenance, and ensuring the normal operation of the fire protection system.
[0003] In practice, existing lifting devices for fire equipment maintenance, through the use of clamps and auxiliary support structures, can meet the basic needs of maintaining equipment such as pipes and sprinkler heads. However, the following problems still exist:
[0004] When common fire equipment maintenance lifting devices are used to lift, install, and maintain fire water pipes, most of these devices rely on clamps and positioning pins to position and fix the pipes, making it difficult to fit fire water pipes of different diameters. This results in inaccurate initial positions of the pipes during fixing. Furthermore, the shaking generated by the device during lifting can cause secondary displacement of the pipes, affecting the accuracy of the connection and maintenance efficiency. Therefore, this application provides a fire equipment maintenance lifting device to meet these needs. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a lifting device for fire equipment maintenance.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lifting device for fire equipment maintenance, comprising a support frame, and further comprising:
[0007] A positioning assembly includes a protective shell disposed on the side of a support frame, a connecting plate rotatably connected to the inner cavity of the protective shell, a sleeve fixed to the side of the connecting plate, a fixing plate disposed on the top of the sleeve, a flexible clamping plate rotatably connected to the top of the fixing plate, and a first spring sheet fixed to the side of the flexible clamping plate.
[0008] An auxiliary component, comprising a mounting bracket installed at one end of the protective housing, wherein an elastic joint is fixed to the side of the mounting bracket.
[0009] Furthermore, a fixing block is slidably connected to the inner cavity of the sleeve, and a sliding rod is fixed to the top of the fixing block.
[0010] The technical effect of adopting the above technical solution is that by setting a fixed block, it can work with the limiting block to ensure that the slide rod can perform translational movement.
[0011] Furthermore, a first groove is formed on the outer surface of the sleeve, and the top of the slide rod is fixed to the bottom of the fixing plate.
[0012] The technical effect of adopting the above technical solution is that by opening the first groove, the slide rod can be made to translate when the sleeve rotates.
[0013] Furthermore, a fixing rod is fixed to the side of the slide bar, and a contact block is fixed to the top of the fixing plate.
[0014] The technical effect of adopting the above technical solution is that by setting a fixed rod, another set of positioning components can be moved synchronously, and by setting a contact block, the flexible clamp can be limited.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0016] By setting a protective shell, the sleeve can be protected. A drive motor is set on the side of the connecting plate. By starting the motor, the sleeve can be rotated clockwise by the connecting plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a lifting device for fire equipment maintenance, including a support frame 1, and further comprising:
[0027] Positioning component 2 includes a protective shell 21 disposed on the side of the support frame 1. A connecting plate 22 is rotatably connected to the inner cavity of the protective shell 21. A sleeve 23 is fixed to the side of the connecting plate 22. A fixing plate 28 is disposed on the top of the sleeve 23. A flexible clamping plate 210 is rotatably connected to the top of the fixing plate 28. A first spring piece 211 is fixed to the side of the flexible clamping plate 210.
[0028] Auxiliary component 3 includes a mounting bracket 31 installed at one end of the protective shell 21. An elastic joint 32 is fixed to the side of the mounting bracket 31. A fixing block 24 is slidably connected to the inner cavity of the sleeve 23. A sliding rod 25 is fixed to the top of the fixing block 24. A first groove 27 is formed on the outer surface of the sleeve 23. The top of the sliding rod 25 is fixed to the bottom of the fixing plate 28. A fixing rod 26 is fixed to the side of the sliding rod 25. A contact block 29 is fixed to the top of the fixing plate 28. A second groove 213 is formed on the top of the fixing plate 28. A contact block 29 is fixed to the side of the fixing plate 28. There is a second spring 212, and a slider 214 is provided at the bottom of the flexible clamping plate 210. The end of the slider 214 away from the flexible clamping plate 210 is slidably connected to the inner cavity of the second groove 213. The first groove 27 is designed in a spiral shape. By activating the drive motor located on the side of the connecting plate 22, the sleeve 23 can be made to rotate clockwise, which in turn can drive the slide rod 25 to move along the inner cavity of the first groove 27 towards the side closer to the support frame 1. During the movement of the slide rod 25, the fixed block 24 and the two sides of the slide rod 25 are connected to the slide rod 25. The side-mounted limiting block ensures that the slide bar 25 maintains its translational movement. The fixed rod 26 synchronously drives another set of positioning components 2. When the slide bar 25 reaches a certain position, the flexible clamping plate 210 and the first spring piece 211, which are rotatably connected to the top of the fixed plate 28, contact the side of the water pipe. This causes the flexible clamping plate 210 to rotate, increasing the contact area between the flexible clamping plate 210 and the outer surface of the water pipe. This effectively improves the stability of the water pipe during lifting and transportation, facilitating the inspection of the water pipe. During maintenance and replacement, when the flexible clamp 210 rotates to a certain position, the other side of the flexible clamp 210 contacts the side of the contact block 29, thereby fixing the position of the flexible clamp 210. During the movement of the flexible clamp 210, the movement trajectory of the flexible clamp 210 can be limited and supported by the cooperation of the second groove 213 and the slider 214, ensuring the stability of operation. By fixing the second spring piece 212 to the side of the flexible clamp 210, the water pipe can be flexibly clamped to avoid damage to the water pipe.
[0029] Furthermore, such as Figure 2 and Figure 3 As shown: A flexible gasket 33 is fixed to the side of the elastic joint 32. By setting the mounting bracket 31, the elastic joint 32 and the flexible gasket 33 can be supported. The elastic joint 32 and the flexible gasket 33 cooperate to provide flexible support for the water pipe. When the lifting device is activated to lift the water pipe and sway, the elastic joint 32, the flexible gasket 33 and the first spring piece 211 cooperate to absorb the vibration stress transmitted to the water pipe, reduce the impact of vibration on the water pipe, improve the docking accuracy, and facilitate maintenance and replacement.
[0030] Working principle:
[0031] like Figure 1-4 As shown:
[0032] In use: First, place the prepared water pipe on top of the protective shell 21. Then, start the drive motor located on the side of the connecting plate 22. The motor's output shaft rotates clockwise, which in turn drives the sleeve 23 to rotate clockwise via the connecting plate 22. This causes the slide rod 25 to move along the inner cavity of the first groove 27. When the slide rod 25 moves, the fixed rod 26 synchronously drives another set of positioning components 2 to move. The fixed plate 28 drives the flexible clamping plate 210 and the first spring piece 211 to move. When the flexible clamping plate 210 moves to a certain position, the first... The sides of the spring piece 211 and the second spring piece 212 contact the outer surface of the water pipe, thereby causing the flexible clamp 210 to rotate. When the flexible clamp 210 moves to a certain position, the side of the flexible clamp 210 away from the first spring piece 211 contacts the side of the contact block 29, thereby increasing the reverse stress on the flexible clamp 210, which in turn can position and clamp the water pipe. During the clamping process, the elastic joint 32 and the flexible pad 33 cooperate to provide flexible buffering for the water pipe, avoiding the impact of shaking on the water pipe during lifting and lowering, which could cause the water pipe to shift position, affecting the docking accuracy and maintenance efficiency.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
