[0006] By adopting the above technical solution, the frame serves as the main structure, and the rubber wheels on both sides of the bottom allow the entire device to move flexibly, facilitating equipment transfer. The rubber buffer layer minimizes impacts and collision damage when the frame lifts the water pump.

[0007] Furthermore, the fixing mechanism includes a lifting frame, and a sliding frame is rotatably connected to the top of the lifting frame.

[0008] By adopting the above technical solution, the fixing mechanism includes a lifting frame, which allows the height of the device to be adjusted as needed during disassembly, thereby making it easier to access and operate the water pump shaft.

[0009] Furthermore, the sliding frame has a slot inside, and a clamp is slidably connected inside the slot.

[0010] By adopting the above technical solution, the slots inside the sliding frame provide a sliding track for the clamp, allowing the clamp to be flexibly adjusted according to the size of the water pump shaft.

[0011] Furthermore, a double-ended stud is rotatably connected inside the slot, and the double-ended stud is threadedly connected to the clamp.

[0012] By adopting the above technical solution, the double-ended stud inside the slot is rotatably connected to the clamp thread, so that the clamping force of the clamp can be adjusted by rotating the double-ended stud, thereby achieving a firm fixation of water pump shafts of different sizes.

[0013] Furthermore, the lifting frame includes a connecting rod assembly, which consists of two sets, with a threaded rod between the two sets of connecting rod assemblies.

[0014] By adopting the above technical solution, the lifting frame includes a connecting rod assembly, making the structure of the lifting frame more stable and reliable.

[0015] Furthermore, the connecting rod assembly includes a first connecting rod, a second connecting rod, and a connecting piece for connection.

[0016] By adopting the above technical solution, the connecting rod assembly includes a first connecting rod, a second connecting rod, and a connecting piece for connection, making the structure of the lifting frame more reliable.

[0017] Furthermore, one of the connecting pieces and the threaded rod are rotatably connected, and the other connecting piece and the threaded rod are rotatably connected.

[0018] By adopting the above technical solution, one connecting piece and the threaded rod are rotatably connected, and the other connecting piece and the threaded rod are also rotatably connected, so that the threaded rod can rotate smoothly between the two sets of connecting rods, thereby realizing the height adjustment of the lifting frame.

[0019] Furthermore, the bottom of the sliding rod is provided with rollers, and multiple rollers are provided, which are arranged linearly and equidistantly.

[0020] By adopting the above technical solution, the rollers and multiple rollers at the bottom of the sliding rod are arranged linearly and equidistantly, which reduces friction and improves sliding efficiency during the sliding process.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model is designed with a frame, a fixed frame, a sliding rod, a fixing mechanism, rubber wheels, and a hook. The frame serves as the main structure of the entire device, and the rubber wheels at the bottom enable flexible movement of the device. The hook acts as a bridge connecting the frame and the lifting equipment, allowing the entire device to be easily lifted by hoisting. This allows maintenance personnel to easily operate the equipment in complex or confined spaces. The rubber wheels and rubber buffer layer not only reduce friction during movement and protect the surrounding pipes and pump body from damage, but also allow the pump to be rotated from vertical to horizontal after landing, preventing damage to the fire-fighting equipment due to collision.

[0023] 2. This utility model uses several rollers to reduce friction, allowing the sliding rod to move easily within the frame. By using several rollers and distributing them evenly, the ease and flexibility of the sliding rod's movement can be improved.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Example 1:

[0032] A fire protection facility and equipment maintenance device, such as Figures 1-4 As shown, the device includes a frame 1, with rubber wheels 6 on both sides of the bottom of the frame 1, a hook 7 on one side of the frame 1, and a fixed frame 2 rotatably connected to the top of the frame 1. Multiple sets of fixed frames 2 are provided, one set of which has a card 3 rotatably connected to its bottom. A sliding rod 4 is slidably connected inside the frame 1, with a fixing mechanism 5 at one end of the sliding rod 4. Rubber buffer layers are provided on the bottom of the frame 1 and on the fixed frames 2. The hook 7 on one side of the frame 1 facilitates connection with lifting equipment, enabling the lifting and transport of the device. The multiple sets of fixed frames 2 rotatably connected to the top of the frame 1 allow for quick connection to the water pump, improving the device's practicality. The card 3 rotatably connected to the bottom of one set of fixed frames 2 provides stable support for the fire-fighting equipment during maintenance, preventing the equipment from slipping. The rubber buffer layers on the bottom of the frame 1 and on the fixed frames 2 further protect the fire-fighting equipment and surrounding pipes from damage.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixing mechanism 5 includes a lifting frame 501, and a sliding frame 502 is rotatably connected to the top of the lifting frame 501. The sliding frame 502 rotatably connected to the top of the lifting frame 501 allows the fixing mechanism 5 to flexibly adjust its height to adapt to fire-fighting equipment of different sizes, thus improving the adaptability of the device.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The sliding frame 502 has a slot 503 inside, and a clamp 504 is slidably connected inside the slot 503. The clamp 504 fixes the water pump shaft by clamping, ensuring stability and safety during disassembly.

[0035] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The slot 503 has a double-ended stud 505 inside for rotational connection. The double-ended stud 505 and the clamp 504 are threaded together, which makes it easy for maintenance personnel to quickly adjust the position and clamping force of the clamp 504 during operation, thus improving work efficiency.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4The lifting frame 501 includes a connecting rod assembly 506, which has two sets. A threaded rod 507 is provided between the two sets of connecting rod assemblies 506. The threaded rod 507 between the two sets of connecting rod assemblies 506 can adjust the distance between the connecting rod assemblies 506 by rotating the threaded rod 507, thereby realizing the height adjustment of the lifting frame 501 and improving the flexibility and adaptability of the device.

[0037] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting rod assembly 506 includes a first connecting rod 508, a second connecting rod 509, and a connecting piece 510 for connection. It improves the load-bearing capacity of the lifting frame 501 and also enables the device to maintain a stable posture during maintenance.

[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 4 One of the connecting pieces 510 and the threaded rod 507 are rotatably connected, and the other connecting piece 510 and the threaded rod 507 are rotatably connected, ensuring the stability and reliability of the lifting frame 501 during the height adjustment process.

[0039] The implementation principle of this utility model is as follows: First, the fixing frame 2 is fixed on the water pump to provide a stable support point for subsequent hoisting. Then, the card 3 is rotated so that its bottom lifts the water pump, forming a support surface at the bottom of the water pump, which reduces the direct pressure on the water pump.

[0040] Use a hand chain hoist to lift the frame 1. The frame 1 is connected to the hand chain hoist through the rubber wheel 6 and hook 7 at its bottom to ensure the stability of the lifting. When the frame 1 is lifted, it will rise together with the water pump fixed on it and gradually leave the installation position.

[0041] The hoisted water pump is slowly lowered to the ground. The rubber wheels 6 at the bottom of the frame 1 play a role in protecting the water pump from damage. The frame 1 is pulled, and the rolling property of the rubber wheels 6 is used to move the water pump to a wider and more convenient place for maintenance.

[0042] Insert the sliding rod 4 into the frame 1 and adjust its height as needed. Rotate the threaded rod 507 to adjust the height of the sliding rod 4 through the threaded connection, ensuring that it can fit tightly against the water pump shaft. Rotate the double-ended stud 505 so that the clamp 504 can clamp the water pump shaft. The clamp 504 is located inside the slot 503 of the sliding frame 502. The clamping is achieved by rotating the double-ended stud 505. Pull the sliding rod 4 outward and use the clamping force of the clamp 504 to pull the water pump shaft out of the water pump housing, reducing the collision and damage to the water pump coil. Transport the disassembled water pump housing and water pump shaft to the maintenance area for necessary maintenance and inspection. After that, transport them back to their original location for reassembly so that the water pump can resume normal operation.

[0043] Example 2:

[0044] See Figure 5 The bottom of the sliding rod 4 is equipped with rollers 8. There are multiple rollers 8 arranged linearly and equidistantly, which allows the device to be adjusted in position and direction more flexibly during maintenance, improving work efficiency and flexibility. The rollers 8 also protect the contact surface between the sliding rod 4 and the frame 1 from wear and damage, extending the service life of the device.

[0045] The implementation principle of this utility model is as follows: First, the roller 8 allows the sliding rod 4 to be pulled outward, thereby reducing friction and improving disassembly efficiency.
