[0002] The counter-camber is a waterproof structure between the roof waterproof layer and the protruding structure. Before construction, it is a crucial step to chisel the concrete surface of the counter-camber part. The chiseling treatment aims to physically remove the floating slurry and loose weak layer on the concrete surface, increase the bonding area and mechanical biting force between the newly poured concrete and the existing concrete, so as to improve the integrity and durability of the combination of the new and old concrete.

[0003] Currently, on-site construction generally uses manual hand-held electric drills for chiseling operations. This method not only has low efficiency, as workers need to chisel each part meticulously, resulting in high labor intensity, but also the operation quality is greatly affected by human factors, making it difficult to ensure the uniformity and consistency of the chiseling treatment. In addition, long-term manual operation may cause worker fatigue and increase the construction safety risk. Content of the Utility Model

Specific embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] Such as Figure 1-2As shown in the figure, the utility model provides an efficient secondary structure anti-camber chiseling construction device, which includes a trolley body 10. The bottom of the trolley body 10 is open. Two mounting bosses 12 are symmetrically arranged on the left and right sides of the trolley body 10. Two electric telescopic rollers 20 are arranged at the bottom of the mounting bosses 12. A push rod 11 is arranged at the rear of the trolley body 10. A bearing seat 13 is arranged at the top of the mounting boss 12. A chiseling device 30 is arranged inside the trolley body 10. Both ends of the chiseling device 30 penetrate through the side walls of the trolley body 10 and are hinged between the two bearing seats 13. A driving motor 40 and a control box 50 are arranged at the top of the trolley body 10. The driving motor 40 is connected to the chiseling device 30 through a belt transmission. The control box 50 is electrically connected to the driving motor 40 and the electric telescopic rollers 20 respectively. When chiseling, the trolley body 10 is pushed to the chiseling area, the vehicle body is lowered through the electric telescopic rollers 20, and then the driving motor 40 drives the chiseling device 30 to rotate, so that the chiseling hammer 35 chisels the concrete floor evenly. Compared with manual step-by-step chiseling, this method has higher efficiency, better uniformity and consistency of chiseling, significantly improves the construction efficiency, reduces the labor intensity of workers and ensures the construction quality.

[0024] As Figure 4 shown, the electric telescopic roller 20 includes an electric telescopic rod 22. The top of the electric telescopic rod 22 is a mounting plate 23. The mounting plate 23 is fixedly arranged at the bottom of the mounting boss 12 through bolts. A roller 21 is arranged on one side of the bottom of the electric telescopic rod 22. The electric telescopic rod 22 is electrically connected to the control box 50. The lifting of the trolley body 10 can be freely controlled through the electric telescopic rod 22. During non-construction time, the trolley body 10 rises, and the chiseling device 30 does not contact the ground, which is convenient for passage. When the trolley body 10 descends, the chiseling device 30 contacts the ground, which is convenient for construction.

[0025] As Figure 3 shown, the chiseling device 30 includes a main shaft 31. A hollow shaft 32 is arranged in the middle of the main shaft 31. A plurality of discs 33 are arranged on the outer surface of the hollow shaft 32. A plurality of mounting holes 3301 are equally divided at the periphery near the edge on the left side of the disc 33. A chain shaft 34 is arranged in the coaxial mounting holes 3301 on each disc 33. The chain shaft 34 between any two adjacent discs 33 is a mounting part, and a chiseling hammer 35 is hinged on the mounting part.

[0026] Among them, both ends of the main shaft 31 penetrate through the two sides of the trolley body 10 and are hinged to the two bearing seats 13. A belt pulley is arranged on the right side of the main shaft 31. A belt pulley of the same model is arranged on the output shaft of the driving motor 40. The two belt pulleys are connected by a belt.

[0027] In this embodiment, the installation parts between the two discs 33 are taken as a group, and the chiseling hammers 35 installed in each group are arranged at intervals, and the chiseling hammers 35 between adjacent groups are staggered. This staggered design can prevent the chiseling hammers 35 from colliding with each other during the rotation with the main shaft 31, affecting the effect of chiseling the concrete floor.

[0028] In one embodiment, the number and arrangement of the chiseling hammers 35 can be adjusted according to the construction dimension width of the anti-camber. For example, if the width is small, the number can be gradually reduced from both ends of the chain shaft 34 to the middle, so as to change the chiseling width when the chiseling device 30 rotates.

[0029] In this embodiment, the chiseling hammer 35 includes a chain 3501. One end of the chain 3501 is hinged on the installation part, and the other end is hinged with a hammer body 3502. A positioning ring 36 is arranged on the installation part where any chain 3501 is located. The positioning ring 36 presses the chain 3501 against one side of the disc 33, preventing the chain 3501 from swaying left and right on the installation part and causing uneven chiseling marks on the concrete floor.

[0030] As a preferred embodiment, the positioning ring 36 is made of rubber. Since the surface of the chain 3501 is arc-shaped and cannot maintain stability between the chain shaft 34 and the disc 33, the rubber positioning ring 36 has a certain extrusion deformation ability and can better fix it on one side of the installation part.

[0031] In one embodiment, a brush is arranged at the bottom of the trolley body 10. The brush includes a connecting plate. A threaded hole is arranged at the top of the connecting plate, and bristles are arranged at the bottom of the connecting plate. There are four brushes, which are respectively arranged at the edges of the bottom of the trolley body 10. When the electric telescopic roller 20 is fully retracted, the bristles are in contact with the ground. The bristles can block the gravel splashing from the bottom of the trolley body 10 during the chiseling process, avoiding the injury to the legs caused by sputtering, and at the same time can also reduce the dust propagation speed generated and avoid excessive dust.

[0032] Specifically, the working principle of this efficient secondary structure anti-camber chiseling construction device: Push the trolley body 10 to the concrete floor in the area to be chiseled. Control the electric telescopic rod 22 to fully retract through the control box 50, so that the chiseling hammer 35 is in contact with the concrete floor, and then control the driving motor 40 to drive the rotation of the chiseling device 30. At this time, several chiseling hammers 35 make a circular motion around the main shaft 31 under the influence of centrifugal force to chisel the ground, and finally form a uniform chiseling area. Through the above structure, the problems of low efficiency, high labor intensity, difficult guarantee of the uniformity and consistency of chiseling treatment, and easy fatigue of workers caused by long-term manual operation and increased construction safety risks in the existing manual chiseling method are solved.

[0033] The above further describes the present utility model by means of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
