Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment, and in particular to a rust removal device for municipal manhole covers. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Cast iron manhole covers are prone to rusting, requiring rust removal equipment to grind and remove the rust. In actual use, this involves manually spraying a rust-converting agent onto the surface of the manhole cover, and then evenly applying the agent with a cleaning brush. This process is time-consuming, labor-intensive, inefficient, and costly. Therefore, developing a new rust removal device for municipal manhole covers has become an urgent problem for technicians in this field. Utility Model Content

[0003] The purpose of this invention is to provide a municipal manhole cover rust removal device to solve the problems of low efficiency, time and labor costs associated with manually spraying rust-converting agents onto the surface of manhole covers.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a municipal manhole cover rust removal device, comprising a first horizontal plate and a second horizontal plate. The first horizontal plate is fixedly mounted on the second horizontal plate by a column, and a working groove is formed on the second horizontal plate. A liftable third horizontal plate is arranged between the first and second horizontal plates. A brush plate that cooperates with the working groove is arranged below the third horizontal plate. The rotating shaft at the upper end of the brush plate is connected to a first drive motor on the third horizontal plate. An annular groove is formed on the upper surface of the brush plate. A first liquid outlet and a second liquid outlet are arranged in the annular groove that cooperate with a water injection pipe at the lower end of the third horizontal plate. The first liquid outlet communicates with a dispersion chamber in the brush plate. Brush bristles are provided at the lower end of the dispersion chamber. The second liquid outlet penetrates the brush plate.

[0006] Furthermore, a first water tank and a water pump are provided on the first horizontal plate, and the first water tank is connected to the water injection pipe at the bottom of the third horizontal plate through the water pump and the water supply pipe.

[0007] Furthermore, the top end of the water injection pipe is fixedly mounted on the third horizontal plate, and the bottom end of the water injection pipe slides in conjunction with the annular groove on the brush plate.

[0008] Furthermore, a caster is provided at the bottom of the second horizontal plate, and a push handle is provided at the left end of the second horizontal plate.

[0009] Furthermore, a drive column is fixedly installed at the top of the third horizontal plate via a connecting plate, and a limiting block that cooperates with the drive block is provided on the drive column. A lead screw is rotatably provided between the first horizontal plate and the second horizontal plate, and the drive block is threadedly engaged with the lead screw.

[0010] Furthermore, the lead screw is driven by a second drive motor on the first horizontal plate.

[0011] Furthermore, the drive block is slidably engaged with the drive column, and the drive column is provided with a spring that engages with the drive block.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model of a municipal manhole cover rust removal device features a brush disc with a first and a second liquid outlet. The rust-converting agent in the first outlet is slowly and evenly distributed onto the brush bristles through a dispersion chamber, while the rust-converting agent in the second outlet is directly sprayed onto the manhole cover. These two application methods occur simultaneously, effectively ensuring even application of the rust-converting agent and guaranteeing rust removal efficiency. The brush disc is driven by a first drive motor, simultaneously spraying the rust-converting agent and grinding the manhole cover surface to remove rust, effectively freeing up manpower and improving work efficiency. In summary, this utility model of a municipal manhole cover rust removal device has a simple structure, practical function, and ingenious design, effectively solving the problems of low efficiency and time-consuming and labor-intensive manual spraying of rust-converting agent onto manhole cover surfaces.
