Technical Field

[0001] The present application relates to the technical field of repair devices, and in particular to a reinforced concrete repair device. Background Art

[0002] With the acceleration of urbanization, a large number of old buildings are facing the need for maintenance and repair. As one of the most commonly used building materials, reinforced concrete is widely used in various construction projects due to its high strength and durability. However, during long-term use, due to the influence of factors such as natural environmental erosion and excessive loads, reinforced concrete structures are prone to corrosion and cracks, which seriously affect the safety and service life of buildings.

[0003] At present, for the repair of reinforced concrete structures, when there is severe corrosion, weathering or loose concrete, it is necessary to remove the concrete of the problematic part before repairing. However, when removing, a sampling hammer or chisel is usually used to chisel off the problematic part of the reinforced concrete structure, and then the chiseled part is cleaned to reduce residual powder, debris and other impurities, and then water is sprinkled to keep the reinforced concrete structure moist, and then the chiseled part is repaired with concrete, so that the entire repair process takes a long time.

The repair device also includes a rotating roller 12, which is rotatably connected between the two mounting plates, and a sawtooth 121 is fixedly connected to the outer peripheral side of the rotating roller 12, and the sawtooth 121 has multiple and evenly spaced arrangements. A power assembly 2 is arranged in the bearing seat 1, which is used to drive the rotating roller 12 to rotate. The power assembly 2 includes a power belt 21 and a power motor 22, and the power motor 22 is installed and fixed in the bearing seat 1. A battery is installed and fixed in the bearing seat 1, and the battery is electrically connected to the power motor 22 to provide energy for the power motor 22. The power belt 21 is slidably arranged in the bearing seat 1, and the power belt 21 is connected end to end. The power belt 21 is sleeved on the output shaft of the rotating roller 12 and the power motor 22. When the power motor 22 is started, the power belt 21 drives the rotating roller 12 to rotate. When the reinforced concrete is repaired, the concrete to be repaired is excavated through the sawtooth 121.

[0068] The repair device also includes an isolation cover 3 and a water storage box 4. An isolation groove is formed on the side wall of the bearing seat 1 facing away from the handle. The isolation groove is in a "mouth" shape and surrounds the mounting plate. The isolation cover 3 is slidably connected to the isolation groove. When in use, the isolation cover 3 abuts against the surface of reinforced concrete, so that the isolation cover 3 covers the rotating roller 12, reducing the possibility of debris scattering when excavating concrete. When the rotating roller 12 rotates, the saw teeth 121 drive the concrete debris and powder to be thrown below the rotating roller 12.

[0069] The inner wall of the isolation cover 3 is fixedly connected to a limiting block, and the isolation groove wall is connected to form a limiting groove. The limiting block is slidably connected in the limiting groove to reduce the possibility of the isolation cover 3 detaching from the isolation groove. The bearing seat 1 is provided with an elastic driving member, which is used to drive the isolation cover 3 to slide outward from the bearing seat 1 so as to maintain a state of protruding from the isolation groove. The elastic driving member is a driving spring 13, and there are multiple driving springs 13 and they are evenly arranged in the isolation groove. One end of the driving spring 13 abuts on the side wall of the isolation cover 3, and the other end of the driving spring 13 abuts on the groove wall of the isolation groove away from the notch. When the driving spring 13 is elastically released, it pushes the isolation cover 3 to slide outward from the isolation groove.

A water outlet pipe 142 is fixedly installed on the water outlet side of the water pump 14, and the water outlet pipe 142 is a hose structure. The water outlet pipe 142 is penetrated through the water storage box 4 and the isolation cover 3, and the water outlet pipe 142 is connected to the water delivery tank 31 away from the side of the water pump 14. When the water pump 14 is started, the water pipe 141 draws the water stored in the water storage tank 41, and then the water flows into the water delivery tank 31 through the outlet pipe 142, and then the water is sprayed out from the water spray hole 32 to moisten the concrete, on the one hand to reduce the temperature of the saw teeth 121, and on the other hand to flush the excavation position to reduce the amount of debris and powder.

[0072] A collecting groove 33 is formed on the inner side of the bottom wall of the isolation cover 3. The collecting groove 33 extends along the axial direction of the rotating roller 12. The collecting groove 33 is located at a position of the isolation cover 3 away from the bearing seat 1, and is used to collect the excavated concrete debris, powder and water flow. A transmission pipe 34 is fixedly penetrated in the isolation cover 3. The transmission pipe 34 is slidably connected to the bearing seat 1 and extends to the outside of the bearing seat 1.

When the side plate 69 is removed, the vertical groove wall on one side of the filter groove 61 and the storage groove 64 is in an open state, and the winding roller 66 and the winding roller 67 are exposed outside the seat body 68.

[0087] See also Fig. 9 and Fig.10The outer peripheral sides of the winding roller 66 and the winding roller 67 are connected with a connecting strip 9 in an axially sliding manner. The connecting strip 9 is a "T"-shaped structure. The two ends of the water filter net 63 are respectively fixedly connected to the connecting strip 9 of the winding roller 66 and the winding roller 67. When the connecting strip 9 is slidably separated from the winding roller 66 and the winding roller 67, the connecting strip 9 can drive the water filter net 63 to separate from the filter seat 6, and the water filter net 63 can be cleaned or replaced.

[0088] The implementation principle of a reinforced concrete repair device in the embodiment of the present application is:

[0089] When excavating the concrete to be repaired, align the rotating roller 12 with the position to be repaired and place the isolation cover 3 against the concrete surface, then push the bearing seat 1 so that the saw teeth 121 on the outer peripheral side of the rotating roller 12 excavate the position to be repaired. At the same time, during excavation, the water spray hole 32 sprays water, which cools the saw teeth 121 on the one hand, and the debris and powder impurities at the excavation position flow into the collection tank 33 on the other hand, and then the transmission pipe 34 inputs the water flow and impurities into the filter tank 61, so that the water flow is filtered and flows into the storage tank 64 for recycling and reuse. When the concrete excavation is completed, the excavation position is further cleaned, and then the concrete is kept moist before filling.

[0090] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
