Description

Technical Field

[0001] The utility model relates to a disassembly device, in particular to a disassembly device for a heat exchanger. Background Art

[0002] The mill cooling system is equipped with a heat exchanger for temperature regulation. This heat exchanger primarily operates on the principle of a partitioning heat exchanger: a solid partition separates the hot and cold fluids. Heat transfer between the two fluids occurs through heat conduction through the partitioning wall and convection along the partitioning wall. This heat exchanger utilizes a shell-and-tube, double-tube, or other partitioning structure, allowing some of the heat from the hot fluid to be transferred to the cold fluid, thereby achieving cooling or heating.

[0003] After a long period of use, the heat exchanger needs to be replaced or cleaned. Since the heat exchanger is heavy, it requires multiple people to drag it to move it, which is time-consuming and labor-intensive. Since the people use different amounts of force, there is a safety hazard of the heat exchanger tipping over during the dragging process. Utility Model Content

[0004] The purpose of the utility model is to provide a heat exchanger disassembly device, which solves the problem of low efficiency and potential safety hazards in replacing heat exchangers.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is:

[0007] Furthermore, the first moving component is connected to the support frame through a first sliding component.

The transmission rod is connected to the output end of the motor, and the two ends of the transmission rod are respectively connected to the gears. The racks are arranged on the inner walls on both sides of the support frame, and the gears are respectively engaged with the racks; the moving beam is located above the support frame, and the transmission rod is connected to the moving beam through a connecting piece.

[0008] Furthermore, the second moving assembly is connected to the moving beam through a second sliding assembly; the second moving assembly includes a cylinder and a moving plate, the moving plate is arranged on the moving beam through the second sliding assembly, and the cylinder is connected to the moving plate through a linkage.

[0009] Furthermore, the lifting winch is arranged on a movable plate, and a through hole is provided on the movable plate, and a hook of the lifting winch passes through the through hole.

[0010] Furthermore, the first sliding assembly includes a first sliding rail and a first sliding block, the first sliding rail is arranged on the support frame, the first sliding block is connected to the bottom of the moving beam, and the first sliding block is adapted to the first sliding rail.

[0011] Furthermore, the second sliding assembly includes a second slide rail and a second slider, the second slide rail is arranged on the moving beam, the second slider is connected to the bottom of the moving plate, and the second slider is adapted to the second slide rail.

[0012] Furthermore, the support frame includes four beams and four angle steels. The four beams are connected end to end to form a rectangular frame. The four angle steels are respectively installed corresponding to the four right angles of the rectangular frame. The bottoms of the four angle steels are respectively connected to universal wheels.

[0013] Furthermore, the front and rear surfaces formed by the four angle steels are respectively connected with X-shaped reinforcement ribs, and the left and right surfaces are respectively connected with figure-eight reinforcement ribs.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0015] The utility model first moves the support frame to the top of the heat exchanger through the universal wheel, and then stops the movement of the support frame and stabilizes it through the brake. The hook of the lifting winch is connected to the heat exchanger, and the technician controls the lifting winch to raise the heat exchanger and disassemble the heat exchanger. Before the heat exchanger is raised, the lifting winch is first controlled by the first moving component and the second moving component to be located directly above the heat exchanger. This prevents the heat exchanger from shaking due to inertia when the lifting winch raises the heat exchanger, eliminating the possibility of injury to the technician during the shaking process. The utility model not only allows for convenient and quick disassembly or installation of the heat exchanger, but also effectively protects the safety of technicians and improves the safety factor of work.

[0020] like Figures 1 to 4As shown, a heat exchanger disassembly device comprises a support frame 1 and a lifting winch 2. The support frame 1 is provided with a first movable assembly, and the lifting winch 2 is connected to a second movable assembly, which is mounted on the first movable assembly. The support frame 1 is provided with multiple universal wheels 3 at its bottom, each of which is equipped with a brake 4. A technician pushes the support frame 1 over the heat exchanger, stops and stabilizes it using brakes 4, and then connects the lifting winch 2 to the heat exchanger. After connecting the lifting winch 2 to the heat exchanger, the technician checks whether the rope of the lifting winch 2 is vertical. If it is tilted, the technician adjusts the lifting winch 2 left-right using the first movable assembly and the lifting winch 2 forward-backward using the second movable assembly until the rope is vertical. This prevents the heat exchanger from swinging forward-backward or left-right due to inertia while the lifting winch 2 is being raised, potentially causing injury to the technician. Or when the space is relatively narrow and the lifting winch 2 cannot be moved to the top of the heat exchanger by the movable support frame 1, the lifting winch 2 can be positioned above the heat exchanger by cooperating with the first movable assembly and the second movable assembly, and finally the heat exchanger can be raised by the lifting winch 2 to complete the disassembly of the heat exchanger.

[0021] The first moving assembly is connected to the support frame 1 via a first sliding assembly. The first moving assembly includes a motor 11, a transmission rod 12, a moving beam 13, a gear 14, and a rack 15. The transmission rod 12 is connected to the output end of the motor 11, and the two ends of the transmission rod 12 are respectively connected to the gear 14. The racks 15 are arranged on the inner walls of both sides of the support frame 1, and the gears 14 are respectively engaged with the racks 15. The moving beam 13 is located above the support frame 1, and the transmission rod 12 is connected to the moving beam 13 via a connecting member 16. When the lifting winch 2 needs to be moved in the left and right directions, the motor 11 is started, and the transmission rod 12 is driven to rotate. The gears 14 on both sides of the transmission rod 12 rotate synchronously, and the gears 14 move along the meshed racks 15, thereby achieving the purpose of controlling the left and right movement of the lifting winch 2. The first sliding assembly includes a first slide rail 17 and a first slider 18. The first slide rail 17 is arranged on the support frame 1, and the first slider 18 is connected to the bottom of the moving beam 13. The first slider 18 is adapted to the first slide rail 17. When the lifting winch 2 moves left and right, the first sliding assembly will reduce the friction force of the lifting winch 2 when moving in the left and right directions, making the movement smoother and improving work efficiency.

[0022] The second moving assembly is connected to the moving beam 13 via a second sliding assembly. The second moving assembly includes a cylinder 21 and a moving plate 22. The moving plate 22 is mounted on the moving beam 13 via the second sliding assembly, and the cylinder 21 is connected to the moving plate 22 via a linkage. When the hoist winch 2 needs to move in the fore-aft direction, the cylinder 21 is activated, and the extension or retraction of the cylinder 21 pushes the moving plate 22, which in turn drives the hoist winch 2 in the fore-aft direction. The hoist winch 2 is mounted on the moving plate 22, which has a through hole through which a hook 23 of the hoist winch 2 passes, connecting the hoist winch 2 to the heat exchanger. The second sliding assembly includes a second rail 24 and a second slider. The second rail 24 is mounted on the moving beam 13, and the second slider is connected to the bottom of the moving plate 22. The second slider mates with the second rail 24. The second sliding assembly reduces friction during the fore-aft movement of the hoist winch 2, ensuring smoother movement and improving work efficiency.

[0023] The support frame 1 comprises four crossbeams 31 and four angle steels 32. The four crossbeams 31 are connected end-to-end to form a rectangular frame. The four angle steels 32 are mounted at the four right angles of the rectangular frame. The bottoms of the four angle steels 32 are connected to the universal wheels 3. The front and rear surfaces of the four angle steels 32 are connected to X-shaped reinforcement ribs 33, and the left and right surfaces are connected to S-shaped reinforcement ribs 34. The reinforcement ribs enhance the strength of the support frame 1 and extend the service life of the device.

[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
