Description

Technical Field

[0001] This invention relates to the field of concrete construction technology, specifically to a device for roughening concrete joint surfaces. Background Technology

[0002] A roughening machine is a tool similar to a chisel used to roughen the surface of a completed main structure, ensuring a strong bond between the surfaces of two construction stages. Roughening machines are typically used in cast-in-place concrete structures. After the cast-in-place slab is poured, it is roughened before the next layer is poured, allowing the concrete to bond firmly. Therefore, a "roughening machine" is also commonly referred to as a "concrete roughening machine."

[0003] Currently, when construction workers use a roughening machine to roughen the concrete surface, in order to increase the working area and make the working surface more complex, they usually swing the roughening machine so that the roughening blocks work in different areas. However, the manual swinging of the machine undoubtedly increases the workload of the workers, causing their physical strength to drop quickly, which in turn affects the progress of the work. In addition, a certain amount of waste is generated during the roughening process, and the waste is scattered on the ground irregularly, which makes it difficult for workers to collect it, causing certain inconveniences.

In addition, under the action of the fourth spring 126 and pressure plate 125, the stop pawl 127 can fit against the surface of the ratchet 122, thereby preventing the ratchet 122 from rotating.

[0056] A limiting block 13 is rotatably provided on the surface of the rotating rod 123. The other end of the limiting block 13 is fixed to the surface of the housing 1. In this embodiment, the rotation of the ratchet 122 is restricted by the limiting block 13, thereby improving the stability of the rotating rod 123 when it rotates.

Several fifth springs 142 are fixed to the surface of the meshing block 141. A driving block 143 is fixed to the other end of each fifth spring 142. Several telescopic rods are arranged between the driving block 143 and the meshing block 141, and are located within the inner cavity of each fifth spring 142.

[0059] Working principle: When in use, the operator can use handle 2 to push the device to the work area and use control module 3 to control pneumatic mechanism 5. Under the action of air compressor 51, connecting pipe 52, piston 53, moving plate 54 and sliding groove 61 and moving block 65 fixed on the surface of moving plate 54, the chipping block 7 is driven to chip the ground. During the operation of piston 53, the first force-applying block 81 fixed on the surface of piston 53 can fit with the first force-receiving block 82, thereby causing transmission rod 83 to slide on the surface of limiting rod 91.

[0060] It is worth noting that, for ease of understanding, the air compressor 51 is drawn on the surface of the casing 4 in this application. However, in practice, for ease of operation and simple construction, some roughening machines will connect the pneumatic system through pipes, which is explained here.

[0061] When the transmission rod 83 slides, the abutment 85 fixed to the surface of the connecting rod 84 can push the first rocking block 86 and the second rocking block 87 to move. As a result, the chisel block 7 fixed to the surface of the first rocking block 86 and the connecting rod 84 can move horizontally, increasing the working area, and thus eliminating the need for the operator to adjust the direction of the chisel block 7 horizontally during the chiseling process.

[0062] When the transmission rod 83 is working, the second force-applying block 111 fixed on the surface of the transmission rod 83 can contact the second force-receiving block 112. Then, under the action of the limiting ring 116, the connecting plate 113 drives the active pawl 121 to work. Under the action of the active pawl 121, the ratchet 122 rotates. Under the action of high-speed pneumatics, the rotating rod 123 rotates at high speed. Then, the meshing block 141 meshing on the surface of the rotating rod 123 drives the cleaning plate 144 to move at high speed. Under the action of the cleaning plate 144, the chiseled waste material can be pushed to both sides of the surface of the housing 1 for easy processing by the staff.

[0063] Furthermore, when the transmission rod 83 moves, the pressing block 151 fixed to the surface of the transmission rod 83 can drive the airbag 152 to be fixed. The first connecting air pipe 153, dust collection box 154, filter plate 155, second connecting air pipe 156 and dust suction hood 157 connected to the airbag 152 can suck up the dust at the bottom of the housing 1, thereby preventing the dust from spreading to the working environment. In addition, during the reset process of the airbag 152, the one-way valve 17 can assist the airbag 152 to reset.
