Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction equipment, and in particular relates to a roughening device for a low side wall of a tunnel. Background Art

[0002] A roughing machine is a tool similar to an "axe" that processes the completed main structure surface so that the construction surfaces of the two construction stages are firmly bonded. Usually, the roughing machine is used in cast-in-place concrete structures. After the cast-in-place slab is poured, it is roughened to pour the next layer so that the concrete can be firmly bonded. Therefore, the "roughing machine" is generally also called the "concrete roughing machine". With the continuous development of tunnel processing technology, tunnels are used more and more widely, from the earliest highway tunnels and railway tunnels to subway tunnels, municipal tunnels, hydropower tunnels, etc. The diversified application of tunnels is crucial to the roughing treatment of tunnels. Although a tunnel roughing machine is disclosed in the Chinese utility model patent with publication number CN210910668U, which can easily adjust the roughing angle and height, a large amount of dust is easily generated during the roughing process, which seriously endangers the environment and the health of construction workers. Therefore, it is urgent to design a tunnel short side wall roughing equipment that can reduce the dust generated during the roughing process. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-4A roughening device for a low side wall of a tunnel comprises a mobile body 1, an adjustable roughening arm and a roughening body, wherein the adjustable roughening arm is installed at the front end of the mobile body 1, and the roughening body is fixedly connected to the end of the adjustable roughening arm away from the mobile body 1, and the roughening body comprises a connecting arm 2, one end of the connecting arm 2 is fixedly connected to the adjustable roughening arm, and the other end is fixedly connected to a mounting seat 3, and a plurality of roughening heads 4 in a rectangular array are arranged on the bottom surface of the mounting seat 3, and a fixed cover 5 is fixedly connected to the periphery of the rectangular array of the roughening heads 4 on the bottom surface of the mounting seat 3, and the fixed cover 5 is fixedly connected to the periphery of the rectangular array of the roughening heads 4. A sliding cover 6 is provided on the outer side of the cover 5, and a plurality of guide rods 7 are fixedly connected to the top of the sliding cover 6. The top of the guide rod 7 penetrates the mounting seat 3 upward and is fixedly connected to a clamping block 8. The guide rod 7 is slidably connected to the mounting seat 3. A spring 9 is sleeved on the portion of the guide rod 7 located between the mounting seat 3 and the sliding cover 6. Support legs 10 are respectively provided on the left and right sides of the rectangular array of the chiseling heads 4 in the fixed cover 5. The top of the support leg 10 is fixedly connected to the mounting seat 3, and the bottom end of the support leg 10 is rotatably installed with a roller 11, so as to facilitate the movement of the chiseling body along the working surface.

[0020] In this embodiment, the length of the guide rod 7 is smaller than the sum of the height of the fixed cover 5 and the thickness of the mounting seat 3, thereby ensuring that under the limiting action of the block 8, the fixed cover 5 and the sliding cover 6 can always maintain partial overlap, avoiding complete separation of the two and causing dust to float.

[0021] In this embodiment, the spring 9 is always in a compressed state, and when the spring 9 is in its longest state, the bottom surface of the sliding cover 6 is flush with the bottom end of the roller 11 .

[0022] In this embodiment, atomizing spray mechanisms are respectively arranged on the front and rear sides of the rectangular array of the chiseling heads 4 in the fixed cover 5, the atomizing spray mechanism is fixed on the bottom surface of the mounting seat 3, the atomizing spray mechanism is connected with a water hose 12, one end of the water hose 12 away from the atomizing spray mechanism passes through the mounting seat 3 upward and is connected to the water tank 13 at the front end of the mobile body 1 along the adjustable chiseling arm, the water hose 12 is connected with a water pump 14, and the water pump 14 is fixedly installed at the front end of the mobile body 1. The water pump 14 transports the water in the water tank 13 to the atomizing spray mechanism through the water hose 12, and then sprays water on the chiseling work surface through the atomizing spray mechanism, thereby reducing the dispersion of dust and achieving the effect of dust reduction.

[0023] In this embodiment, the atomizing spray mechanism includes a water spray pipe 15, which is fixedly mounted on the bottom surface of the mounting seat 3. The length direction of the water spray pipe 15 is parallel to the length direction of the rectangular array of the chiseling heads 4.

The bottom end of the roller 17 is flush with the bottom ends of the left and right walls of the sliding cover 6. When the chiseling work is actually performed, the bottom surface of the sliding cover 6 can be attached to the working surface under the action of the spring 9, thereby reducing the dispersion of dust. The bottom of the front side wall and the bottom of the rear side wall of the sliding cover 6 are both rotatably mounted with rollers 17. When the chiseling body needs to move after completing the chiseling work at a certain position, the roller 11 can facilitate its movement, and the roller 17 can reduce the resistance between the bottom ends of the front and rear side walls of the sliding cover 6 and the working surface, so as to avoid the sliding cover 6 from hindering the movement of the chiseling body.
