Description

Technical Field

[0001] The utility model relates to the technical field of pipeline demolition in the construction industry, and relates to a drain pipe disassembling device. Background Technique

[0002] Building construction refers to the production activities in the implementation stage of project construction and is the construction process of various buildings. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. At present, many residences and pipelines need to be modified due to long time.

[0003] When renovating old communities, when the drain pipe is damaged, it is difficult for an excavator to drive into the community, so it is necessary to manually hold a percussion drill to disassemble the drain pipe. However, when disassembling the drain pipe, it is necessary to hold the percussion drill for a long time. Due to the vibration of the percussion drill, it is easy to cause arm fatigue when holding it for a long time. At the same time, the long working time of the percussion drill will cause overheating, especially when working in summer, which will greatly reduce the work efficiency.

[0004] Therefore, it is of great practical significance to develop a drain pipe disassembling device with good use experience and capable of continuous operation for a long time. Content of the Utility Model

[0005] Due to the above-mentioned defects in the prior art, the utility model provides a drain pipe disassembling device with good use experience and capable of continuous operation for a long time. Taking a percussion drill as the main body, it is provided with a buffer for holding to reduce vibration when the user holds it outside the buffer, thereby reducing the vibration hazard. It is also equipped with a heat dissipation component to dissipate heat from the percussion drill, extend its continuous operation time, and improve work efficiency, overcoming the defects of the existing drain pipe disassembling device - the percussion drill has poor use experience and is difficult to continuously operate for a long time.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A drain pipe disassembling device, comprising an electric percussion drill, a buffer and a heat dissipation component;

[0008] The buffer is sleeved and fixed outside the electric percussion drill, and includes a limit plate, a buffer, a buffer cover and a handle. The limit plate is an annular plate, the buffer cover is a cylindrical structure and annular limit edges extend inward at both ends. The limit plate is installed inside the buffer cover and arranged in the middle of the buffer cover. The buffer is arranged around the limit plate and buffers are provided on both sides of the limit plate. Both ends of the buffer are respectively fixed to the limit plate and the limit edge. A handle is fixed to the outside of the buffer cover;

[0009] The heat dissipation component is installed at the end of the electric impact drill where the drive motor is installed. It includes an air guide cover and a blower. The air guide cover is sleeved on the end of the electric impact drill where the drive motor is installed, and a blower is installed between the air guide cover and the housing of the electric impact drill.

[0010] The drain pipe disassembly device of the present utility model has a reasonable structural design. It uses an impact drill as the main body, and is provided with a buffer component for holding to facilitate shock absorption when the user holds it outside the buffer component, thereby reducing the vibration hazard. It is also equipped with a heat dissipation component to dissipate heat from the impact drill, extend its continuous operation time, and improve the operation efficiency. Compared with the existing impact drills, the modification is relatively small. Those skilled in the art can complete the modification by adding a buffer component and a heat dissipation component to the existing impact drill. The operation is simple, the effect after modification is good, the user experience is good, the continuous operation time is long, and the application prospect is good.

[0011] As a preferred technical solution:

[0012] For the drain pipe disassembly device as described above, the heat dissipation component further includes a heat conduction plate, which is installed at the end of the electric impact drill where the drive motor is installed and is located in the space between the air guide cover and the housing of the electric impact drill. The presence of the heat conduction plate can quickly conduct the heat inside the impact drill, and then discharge the heat through the blower.

[0013] For the drain pipe disassembly device as described above, the heat dissipation component further includes a corrugated heat dissipation pipe;

[0014] The corrugated heat dissipation pipe is installed at the outlet of the air guide cover. Through the corrugated heat dissipation pipe, the outlet direction of the heat dissipation air can be adjusted, and the hot air can be diverted through the heat dissipation pipe to the area where heat can be quickly dissipated, which is convenient for on-site application, thereby avoiding the problem of overheating when the electric impact drill works, and also avoiding the problem that the electric impact drill dissipates heat in the operation area and affects the operator's experience.

[0015] For the drain pipe disassembly device as described above, the handle and the limit plate are respectively welded to the buffer cover.

[0016] For the drain pipe disassembly device as described above, there are two handles in total. The handle is integrally in a U shape and the two handles are symmetrically fixed on both sides of the buffer cover.

[0017] For the drain pipe disassembly device as described above, the buffer includes a damper and a return spring connected to each other;

[0018] One end of the return spring is welded and fixed to the limit plate, the other end is fixed to the damper, and the end of the damper away from the return spring is fixed to the limit edge.

[0019] The above technical solutions are only a feasible technical solution of the present utility model. The protection scope of the present utility model is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0020] The above-mentioned utility model has the following advantages or beneficial effects:

[0021] (1) For the drain pipe disassembling device of the present utility model, by arranging a buffer member, when the electric drill works with up-and-down vibration, the buffer device will play a role in reducing the vibration intensity, thereby reducing the fatigue of the worker's arm and also reducing the occupational diseases caused by long-term vibration of the arm;

The limiting plate 4 is an annular plate. The buffer cover 3 is a cylindrical structure, and annular limiting edges extend inward at both ends thereof. The limiting plate 4 is installed inside the buffer cover 3 and welded to the middle of the buffer cover 3. The buffer 5 is arranged around the limiting plate 4, and buffers 5 are provided on both sides of the limiting plate 4. Both ends of the buffer 5 are respectively fixed to the limiting plate 4 and the limiting edge (the buffer 5 includes a damper 51 and a return spring 52 connected to each other. One end of the return spring 52 is welded and fixed to the limiting plate 4, the other end is fixed to the damper 51, and the end of the damper 51 away from the return spring 52 is fixed to the limiting edge). Two U-shaped handles 6 are welded and fixed to the outside of the buffer cover 3, and the two handles 6 are symmetrically fixed on both sides of the buffer cover 3;

[0034] The heat dissipation member is installed at the end of the electric impact drill 1 where the driving motor is installed. It includes a heat conduction plate 8, an air guide cover 7, a fan 9, and a corrugated heat dissipation pipe 10. The air guide cover 7 is sleeved on the end of the electric impact drill 1 where the driving motor is installed.

[0036] It has been verified that for the drain pipe disassembly device of the present utility model, by setting the buffer member, when the electric drill vibrates up and down during work, the buffer device will play a role in slowing down the vibration intensity, thereby reducing the fatigue of the worker's arm and also reducing the occupational diseases caused by long-term vibration of the arm; by installing the heat dissipation member on the upper part of the motor, the heat dissipation function is improved, overheating caused by long-term work is reduced, its continuous operation duration is extended, and the operation efficiency is improved; compared with the existing impact drill, the modification is small. Those skilled in the art can complete the modification by adding the buffer member and the heat dissipation member to the existing impact drill. The operation is simple, the effect after modification is good, the user experience is good, the continuous operation duration is long, and the application prospect is good.
