Description

Technical Field

[0001] This application relates to the field of building engineering technology, specifically a concrete pavement demolition device. Background Technology

[0002] In construction projects, the demolition of concrete pavement usually plays a crucial role. It is not only an indispensable key step in the renovation or reconstruction of building pavement, but also an important guarantee for the smooth progress of the entire project. By removing the old concrete pavement, the necessary space can be made for the new pavement structure or design to meet the actual needs of the construction project. This complex and delicate process not only requires construction workers to have superb technical skills and precise operation capabilities, but also requires strict adherence to relevant safety regulations and standards.

[0003] Using pneumatic picks to demolish concrete pavements is a common method of road demolition. However, existing pneumatic picks generally require manual operation, and the operation of pneumatic picks causes significant vibration, resulting in a heavy workload for workers, low work efficiency, and potential dust pollution that affects workers' respiratory health and the surrounding environment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a concrete pavement demolition device that facilitates the movement and adjustment of pneumatic picks, making pavement demolition operations easier, eliminating the need for manual pneumatic pick operation, saving manpower, reducing the workload of workers, and improving work efficiency. It also recovers dust generated during the operation, preventing dust from affecting the respiratory health of workers and the surrounding environment. This solves the problems of manual pneumatic pick demolition being laborious, burdensome, and generating dust that negatively impacts the respiratory health of workers and the surrounding environment.

[0005] To achieve the above objectives, this application provides the following technical solution: a concrete pavement demolition device, comprising a base plate, a frame mounted on top of the base plate, a lifting plate on the front of the frame, a pneumatic hammer fixedly connected inside the lifting plate, a cylinder fixedly connected to the top of the frame, the output end of the cylinder fixedly connected to the upper surface of the lifting plate, a dust collection device inside the frame, dust collection pipes arranged at equal intervals fixedly connected inside the dust collection device, four rollers fixedly connected to the bottom surface of the base plate, a damper fixedly connected to the upper surface of the base plate, the top of the damper fixedly connected to the bottom surface of the frame, four columns fixedly connected to the upper surface of the base plate, four sleeves fixedly connected to the outer surface of the frame, the inner walls of the sleeves slidingly engaging with the outer circumferential surfaces of the columns, a spring fixedly connected to the bottom surface of each sleeve, and the bottom of the spring fixedly connected to the upper surface of the base plate.

[0006] The above solution addresses the issue that manual pneumatic hammer demolition is not only laborious and burdensome, but the dust generated during operation can also affect workers' respiratory health and the surrounding environment. By setting up a mobile chassis with a liftable platform on the front, and mounting the pneumatic hammer on the platform, the pneumatic hammer can be easily moved and adjusted, facilitating road demolition and eliminating the need for manual pneumatic hammer operation. This saves manpower, reduces workers' workload, and improves work efficiency. Furthermore, by installing a dust collection device and equidistantly arranged dust collection pipes inside the chassis, the dust generated during the operation can be collected, preventing it from affecting workers' respiratory health and the surrounding environment.

[0007] Furthermore, two guide rods are fixedly connected to the outer surface of the frame, and two guide tubes are fixedly connected to the inside of the lifting plate. The inner walls of the guide tubes are slidably sleeved with the outer circumferential surfaces of the guide rods, respectively.

[0008] The above scheme restricts and supports the lifting platform, ensuring that it always moves longitudinally along the guide tube, thereby improving the stability of the lifting platform and the pneumatic drill operation.

[0009] Furthermore, the suction pipe is made of hard metal, and the front end of the suction pipe is tilted downward at a certain angle.

[0010] The above solution demonstrates that the hard metal suction pipe is more durable and can extend its service life. The suction pipe, with its front end tilted downwards at a certain angle, is directed towards the area where the pneumatic hammer is breaking up the road, thus optimizing the suction effect.

[0011] Furthermore, the frame has a through hole inside, through which the vacuum pipe passes.

[0012] The above solution facilitates the installation of the vacuum cleaner hose by providing convenience for its installation and disassembly.

[0013] Furthermore, the inside of the through hole is fixedly connected with equidistant reinforcing rings, and the inner walls of the reinforcing rings are respectively fixedly sleeved with the outer circumferential surface of the vacuum tube.

[0014] The above-mentioned solutions provide support and reinforcement for the suction pipe, preventing it from loosening or being damaged by vibrations during road demolition operations and improving its stability during operation.

[0015] Furthermore, a mounting plate is fixedly sleeved on the outer circumference of the pneumatic pick, and the mounting plate and the lifting plate are fixedly connected by bolts arranged at equal intervals.

[0016] The above method allows the pneumatic drill to be mounted on the lifting plate using mounting plates and bolts, facilitating the installation and disassembly of the pneumatic drill.

[0017] Furthermore, two handrails are fixedly connected to the upper surface of the base plate, and each handrail has a soft sleeve fixedly fitted onto its outer circumference.

[0018] With the above solution, workers can move by pushing the handrail, which improves the comfort of workers' operation. The design of the soft sleeve effectively reduces the fatigue and discomfort caused to workers' hands during long-term work.

[0019] Furthermore, the vacuuming device has a built-in dust collection box, which is detachable.

[0020] The above solution allows the dust sucked in by the suction pipe to be stored in the dust collection box, and the detachable dust collection box makes subsequent dust cleaning and maintenance more convenient.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This concrete pavement demolition device features a mobile frame with a liftable platform on the front. The pneumatic hammer is mounted on the platform, facilitating its movement and adjustment for easy road demolition. This eliminates the need for manual pneumatic hammer operation, saving manpower, reducing worker workload, and improving efficiency. The frame incorporates a dust collection system with evenly spaced suction pipes to collect dust generated during operation, preventing it from affecting worker respiratory health and the surrounding environment. Dampers and springs cushion and absorb shocks from the frame, protecting the pneumatic hammer and dust collection system, and reducing overall vibration during operation. This further reduces worker workload and solves the problems of manual pneumatic hammer demolition being laborious, burdensome, and generating dust that negatively impacts worker respiratory health and the environment.

The inner walls of the sleeves 11 are slidably fitted with the outer circumferential surfaces of the columns 10, and a spring 12 is fixedly connected to the bottom surface of each sleeve 11, with the bottom of the spring 12 fixedly connected to the upper surface of the base plate 1.

[0032] Please see Figure 1 , Figure 3 and Figure 4 Two guide rods 13 are fixedly connected to the outer surface of the frame 2, and two guide tubes 14 are fixedly connected to the inside of the lifting plate 3. The inner wall of the guide tube 14 is slidably sleeved with the outer circumferential surface of the guide rod 13 to restrict and support the lifting plate 3, so that the lifting plate 3 always follows the guide tube 14 to move vertically, thereby improving the stability of the lifting plate 3 and the pneumatic hammer 4 during operation.

[0033] Please see Figure 1 , Figure 3 and Figure 4The suction pipe 7 is made of hard metal. The front end of the suction pipe 7 is tilted downward at a certain angle. The hard metal material of the suction pipe 7 is more durable and can extend the service life of the suction pipe 7. The suction pipe 7 with the front end tilted downward at a certain angle can be directed towards the road breaking position of the jackhammer 4 to optimize the dust collection effect.

[0034] Please see Figure 1 , Figure 3 and Figure 5 The frame 2 has a through hole 15 inside, through which the suction pipe 7 passes. The through hole 15 facilitates the installation of the suction pipe 7 and provides convenience for the installation and removal of the suction pipe 7.

[0035] Please see Figure 1 , Figure 3 and Figure 5 The through hole 15 is fixedly connected with equidistant reinforcing rings 16. The inner wall of the reinforcing rings 16 is fixedly sleeved with the outer circumferential surface of the suction pipe 7 to support and reinforce the suction pipe 7, so as to prevent the suction pipe 7 from loosening and being damaged by vibration during the road demolition operation, and to improve the stability of the suction pipe 7 during the operation.

[0036] Please see Figure 1 , Figure 3 and Figure 5 The outer circumference of the pneumatic pick 4 is fixedly fitted with a mounting plate 17. The mounting plate 17 and the lifting plate 3 are fixedly connected by bolts arranged at equal intervals. The pneumatic pick 4 can be installed on the lifting plate 3 through the mounting plate 17 and bolts, which facilitates the installation and disassembly of the pneumatic pick 4.

[0037] Please see Figure 1 , Figure 2 and Figure 4 Two handrails 18 are fixedly connected to the upper surface of the base plate 1. Each handrail 18 has a soft sleeve 19 fixedly fitted on its outer circumference. Workers can move by pushing the device through the handrails 18, which improves the comfort of the workers. The design of the soft sleeve 19 effectively reduces the fatigue and discomfort caused to the workers' hands during long-term operation.

[0038] Please see Figure 1 and Figure 5 The vacuum cleaner 6 has a built-in dust collection box 20. The dust collection box 20 is detachable, which allows the dust sucked in by the vacuum pipe 7 to enter the dust collection box 20 for storage. The detachable dust collection box 20 makes subsequent dust cleaning and maintenance more convenient.

[0039] This embodiment of a concrete pavement demolition device features a mobile frame 2 and a liftable lifting plate 3 on the front of the frame 2. A pneumatic pick 4 is mounted on the lifting plate 3, facilitating movement and adjustment of the pick 4, thus simplifying road demolition operations. This eliminates the need for manual hand-held pneumatic pick 4 operation, saving manpower, reducing worker workload, and improving efficiency. The frame 2 contains a dust collection device 6 and equidistantly arranged dust collection pipes 7 to collect dust generated during operation, preventing dust from affecting worker respiratory health and the surrounding environment. A damper 9 and spring 12 provide cushioning and shock absorption for the frame 2, protecting the pneumatic pick 4 and dust collection device 6, and reducing overall vibration during operation. This further reduces worker workload and solves the problems of manual hand-held pneumatic pick 4 demolition being laborious, burdensome, and generating dust that affects worker respiratory health and the surrounding environment.

[0040] It should be noted that roller 8 is a swivel caster, which facilitates movement of the device in any direction and improves the flexibility of the device's movement.

[0041] The working principle of the above embodiments is as follows:

[0042] During road demolition operations, the demolition device can be moved by pushing the handle 18 under the action of the rollers 8. The device is moved to the location of the road surface to be demolished. The cylinder 5 can be activated to drive the lifting plate 3 to move down, thereby moving the pneumatic pick 4 down so that the pneumatic pick 4 contacts the ground and demolishes the ground. The pneumatic pick 4 can be flexibly raised and lowered under the action of the cylinder 5. At the same time, the device can also be moved as needed under the action of the rollers 8, realizing the raising, lowering and moving of the pneumatic pick 4. This makes it easy to adjust the position of the pneumatic pick 4 during the demolition operation, thus completing the road demolition operation more labor-savingly, avoiding continuous reliance on manual labor, and reducing the workload of workers. During the road demolition operation, the dust collection equipment 6 can be activated to collect the dust generated during the operation through the dust collection pipe 7 to avoid dust pollution. When the device vibrates due to the operation of the pneumatic pick 4, the force generated by the vibration will act on the damper 9 and the spring 12. The damper 9 and the spring 12 work together to buffer and reduce shock, thereby protecting the pneumatic pick 4 and the dust collection equipment 6 from shock, and also reducing the overall vibration of the device during operation, further reducing the workload of workers.
