Description

Technical Field

[0001] The utility model relates to the technical field of concrete pump pipe cleaning, in particular to a cleaning device for a concrete pump pipe. Background Art

[0002] With the acceleration of urbanization, municipal road construction and maintenance have become an important issue in urban development. As an important part of municipal roads, the construction quality of inspection wells is directly related to the service life of roads and driving safety. Traditional inspection well construction technology can no longer meet the needs of modern municipal road construction due to large workload, long cycle, and traffic impact. In this context, the reverse construction of municipal road inspection wells can improve the construction efficiency of inspection wells, ensure construction quality, reduce the impact on the surrounding environment, and reduce safety hazards during construction. The reverse construction of municipal road inspection wells uses rotary jet piles or cast-in-place piles for construction. Both technologies can effectively enhance the bearing capacity and stability of the underground soil layer, providing a solid foundation for reverse construction. Concrete pump pipes are used to transport concrete during reverse construction. As a pipeline for transporting concrete, the concrete pump pipe is connected to the concrete pump and transports concrete from the pump truck or pump station to the construction site by pumping. After the concrete is transported, in order to ensure that the concrete pump pipe can be thoroughly cleaned after each use, remove the concrete residue and impurities in the pipe, and prepare for the next use, a cleaning device is usually used to clean the concrete pump pipe. The concrete pump pipe cleaning device is a device specially designed for cleaning concrete pump pipes. It is usually composed of a high-pressure water pump, a nozzle, a nozzle bracket and a related control system. By cleaning the concrete pump pipe with the cleaning device, the residual concrete in the concrete pump pipe can be removed, which can prevent the concrete from accumulating and hardening in the pipe, thereby affecting the pumping effect. At the same time, it can ensure the smooth flow and cleanliness of the pipe, which is conducive to extending the service life of the pump pipe, improving construction efficiency, and reducing maintenance and replacement costs.

Therefore, in order to solve the above problems, a cleaning device for concrete pump pipes is proposed. Utility Model Content

[0023] A cleaning device for a concrete pump pipe comprises a box body, the box body comprises a water tank 1, a water inlet pipe 11 is arranged on the surface of the water tank 1, a water outlet pipe 12 is arranged on the surface of the water tank 1, a high-pressure water pump 13 is fixedly installed on the surface of the water tank 1, a delivery pipe 14 is fixedly connected to the surface of the high-pressure water pump 13, a high-pressure nozzle 15 is fixedly connected to the end of the delivery pipe 14 away from the high-pressure water pump 13, a cleaning table 16 is fixedly connected to the surface of the water tank 1, a support plate 17 is fixedly connected to the upper surface of the water tank 1, a rotating rod 18 is movably connected to the inner side of the supporting plate 17, a scraper 19 is arranged on the surface of the rotating rod 18, and a support plate 17 is fixedly connected to the upper surface of the water tank 17. A motor 110 is fixedly installed on the surface, and a rotating rod 18 is fixedly connected to the output end of the motor 110. The concrete pump pipe is sleeved on the surface of the rotating rod 18. Through the setting of the high-pressure water pump 13, the water in the water tank 1 can be pumped out and transported through the delivery pipe 14, and then the water can be sprayed out through the high-pressure nozzle 15, so that the concrete pump pipe can be cleaned through the high-pressure nozzle 15. The rotating rod 18 is driven to rotate by the motor 110, so that the rotating rod 18 can drive the scraper 19 to rotate, and then the scraper 19 can scrape the inner wall of the concrete pump pipe, which can prevent concrete from remaining in the concrete pump pipe;

[0024] A fixing mechanism is provided on the inner side of the cleaning platform 16, and the fixing mechanism includes a telescopic cylinder 2, which is fixedly installed on the bottom end of the cleaning platform 16, and a connecting block 21 is fixedly connected to the output end of the telescopic cylinder 2, and a movable rod 22 is movably connected to the surface of the connecting block 21, and a movable block 23 is movably connected to the surface of the movable rod 22, and a connecting plate 24 is fixedly connected to the upper surface of the movable block 23, and a limiting plate 25 is fixedly connected to the upper surface of the connecting plate 24, and a rubber pad 26 is fixedly connected to the inner surface of the limiting plate 25, and a movable groove 27 is provided on the inner side of the cleaning platform 16. By setting the rubber pad 26, the friction between the limiting plate 25 and the concrete pump pipe can be increased, so that the limiting plate 25 can be more stable when fixing the concrete pump pipe, thereby achieving a better fixing effect.

[0025] Furthermore, the movable rod 22 is movably connected to the connecting block 21 in four groups, one end of the movable rod 22 is movably connected to the connecting block 21 through a rotating shaft, and the other end of the movable rod 22 is movably connected to the moving block 23 through a rotating shaft. The connecting block 21 and the moving block 23 are connected through the movable rod 22, so that when the telescopic cylinder 2 is extended or retracted, the connecting block 21 can drive the movable rod 22 to move, and then the moving block 23 can drive the connecting plate 24 and the limit plate 25 to move, so as to facilitate the fixation of the concrete pump pipe through the limit plate 25, so that there is no need to manually support and fix the concrete pump pipe during cleaning, and at the same time, through the movement of the limit plate 25, concrete pump pipes of different sizes can be fixed.

[0026] Furthermore, two groups of moving blocks 23 are connected to the connecting plate 24 correspondingly, and the limiting plates 25 are connected to the connecting plate 24 in two groups correspondingly. The moving blocks 23 move on the inner side of the movable groove 27.

[0027] Furthermore, an adjustment mechanism is provided on the inner side of the rotating rod 18, and the adjustment mechanism includes a first screw rod 3, which is movably connected to the inner side of the rotating rod 18, and a first conical tooth 31 is fixedly connected to the surface of the first screw rod 3, and a second screw rod 32 is movably connected to the inner side of the rotating rod 18, and a second conical tooth 33 is fixedly connected to the surface of the second screw 32, and a movable block 34 is threadedly connected to the surface of the second screw 32, and a connecting rod 35 is fixedly connected to the surface of the movable block 34, and a fixed block 36 is fixedly connected to the end of the connecting rod 35 away from the fixed block 36. Through the arrangement of the first conical tooth 31 and the second conical tooth 33, when the first screw rod 3 is rotated, the first conical tooth 31 rotates under the action of the first screw 3, so that the second conical tooth 33 can be rotated and drive the second screw 32 to rotate, thereby facilitating the movement of the movable block 34 to adjust the scraper 19.

[0028] Furthermore, the second screw rod 32 is movably connected to the inner side of the rotating rod 18 in two groups, and the movable block 34 is movably connected to the first screw rod 3 and the second screw rod 32 through a threaded connection. Through the setting of the movable block 34, when the first screw rod 3 and the second screw rod 32 rotate, the movable block 34 can move on the inner side of the rotating rod 18, and then the connecting rod 35 can drive the fixed block 36 and the scraper 19 to move accordingly under the action of the movable block 34, so that the length of the scraper 19 can be adjusted, and then the length of the scraper 19 can be adjusted according to the inner diameter of the concrete pump pipe, so that the scraper 19 can better contact with the inner wall of the concrete pump pipe, and scrape the inner wall of the concrete pump pipe.

[0029] Furthermore, the connecting rod 35 and the movable block 34 are both movable on the inner side of the rotating rod 18, and the fixed block 36 is fixedly connected to the scraper 19 at one end away from the connecting rod 35.

[0030] Working principle: When in use, the concrete pump pipe is sleeved on the surface of the rotating rod 18, and the telescopic cylinder 2 is electrically connected by an external power supply. The staff starts the telescopic cylinder 2 by pressing the switch, and the telescopic cylinder 2 is telescoped to drive the connecting block 21 to move vertically, and then the movable rod 22 will move through the rotating shaft under the action of the connecting block 21, and the moving block 23 will move inside the movable groove 27 under the action of the movable rod 22. The connecting plate 24 will drive the limiting plate 25 to move horizontally under the action of the moving block 23, and the rubber pad 26 will contact the surface of the concrete pump pipe, so that the concrete pump pipe can be limited by the limiting plate 25, and then the concrete pump pipe can be fixed;

[0031] By rotating the first screw 3, the first conical teeth 31 will rotate under the action of the first screw 3, and then the second conical teeth 33 will rotate under the action of the first conical teeth 31 and drive the second screw 32 to rotate. Since the connecting rod 35 is limited by the rotating rod 18, the movable block 34 will move under the action of the first screw 3 and the second screw 32, and then the connecting rod 35 will drive the fixed block 36 to move, so that the length of the scraper 19 can be adjusted, so that the scraper 19 can contact the inner wall of concrete pump pipes of different sizes.
