Description

Technical Field

[0001] This utility model relates to the field of wall spraying technology, specifically to an adjustable-angle wall spraying cleaning device. Background Technology

[0002] In fields such as building maintenance and industrial equipment cleaning, there is a frequent need to clean walls (such as building exteriors and the outer shells of large equipment). Walls often accumulate dust and grease, affecting their appearance or the heat dissipation of equipment. Traditional wall cleaning methods rely heavily on manual wiping or fixed-angle spraying, which is inefficient.

[0003] Currently, most traditional wall spray cleaning devices are designed with a fixed angle, which can only clean the wall in one direction. When facing corners or inclined walls, the cleaning is not thorough. In addition, the device cannot be stored, resulting in a large space occupation and affecting the transfer efficiency. In view of this, we propose an adjustable-angle wall spray cleaning device. Utility Model Content

[0004] The main objective of this invention is to provide an adjustable-angle wall spray cleaning device that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes an adjustable-angle wall spray cleaning device, comprising a vehicle body, an electric lifting platform fixedly connected to the top of the vehicle body, a placement plate fixedly connected to the top of the electric lifting platform, an electric rotating platform fixedly connected to the top of the placement plate, and an adjustment component provided on the output end of the electric rotating platform, the adjustment component comprising: A support base is fixedly connected to the output end of the electric rotary table, and a lifting frame device is rotatably connected to the support base. A fixed base is fixedly connected to the top of the support base, and a threaded rod is threadedly connected to the inner wall of the fixed base; A positioning rod is fixedly connected to one end of the threaded rod, and a rocker arm is fixedly connected to the other end of the threaded rod.

[0006] Preferably, a limit block is snapped onto the top of the support base, an extension platform is fixedly connected to the top of the placement plate, and a buffer pad is fixedly connected to the top of the extension platform. The buffer pad is made of rubber. A slot is provided on the support base, and the limit block can be snapped into the slot. The limit block is used to limit the maximum rotation angle of the lifting frame device, which is 0° or 90°, to prevent the lifting frame device from rotating excessively. When the lifting frame device rotates backward to the lowest position, the buffer pad contacts the outer wall of the lifting frame device to buffer the impact.

[0007] Preferably, the lifting frame device includes a lifting main frame, a lifting motor, a lifting slide plate, a lead screw, and a guide rod. The outer wall of the lifting main frame is rotatably connected to the support base. The lifting motor is fixed to the inner wall of the lifting main frame, and its output end is connected to the lead screw. The lead screw is threadedly connected to the lifting slide plate. The guide rod passes through the lifting slide plate and is fixed at both ends to the lifting main frame. When the lifting motor drives the lead screw to rotate, the lifting slide plate slides up and down along the guide rod. The lifting frame device is an existing design, so it will not be described in detail. An angle component is provided on the lifting slide plate of the lifting frame device.

[0008] Preferably, the angle component includes a mounting platform, the inner wall of which is rotatably connected to a connecting shaft, one end of which is fixedly connected to a clamping seat, and the other end of which is fixedly connected to a gear. The bottom of the mounting platform is fixedly connected to the top of the lifting slide plate in the lifting frame device.

[0009] Preferably, an electric cylinder base is fixedly connected to the top of the mounting platform, a push block is fixedly connected to the output end of the electric cylinder base, a rack is fixedly connected to the inner wall of the push block, a guide rail is fixedly connected to the bottom of the mounting platform, the guide rail has a T-shaped cross-section, and a T-shaped groove adapted to the guide rail is provided on the push block.

[0010] Preferably, the gear and rack mesh with each other, the inner wall of the push block is slidably connected to the outer wall of the guide rail, a limit block is inserted into the clamping seat, a spray pipe is fixedly connected to the inner wall of the limit block, a limit slot is opened on the limit block, and a screw is provided on the clamping seat. First, the limit block is slid into the clamping seat, and then the screw is rotated to make it enter the limit slot, thereby ensuring the fixing effect of the limit block and completing the fixing work of the spray pipe.

[0011] Preferably, a placement frame is fixedly connected to the top of the vehicle body, a water pump is fixedly connected to the top of the placement frame, a water tank is placed in the placement frame, the input end of the water pump is connected to the water tank through a water pipe, and the output end is connected to the spray pipe through a hose, for delivering clean water in the water tank to the spray pipe.

[0012] This invention provides an adjustable-angle wall spray cleaning device. It has the following beneficial effects: (1) The adjustable angle wall spray cleaning device can be driven to rotate around the vertical axis by an electric rotary table. The angle component on the lifting plate is lifted by the lifting frame device, and the electric lifting platform is lifted. The electric cylinder of the angle component drives the rack and pinion gear to adjust the tilt angle of the spray pipe. The three work together to achieve multi-dimensional adjustment of "horizontal rotation + up and down lifting + spray tilting" to ensure cleaning without dead angles.

[0013] (2) When the adjustable angle wall spray cleaning device is stored, the angle of the lifting frame device is changed so that it comes into contact with the buffer belt and is lowered in conjunction with the electric lifting platform, which makes it easy to complete the storage of the device and reduces the space occupied by the device. In conjunction with the wheels of the vehicle, it is easy to move the device. Attached Figure Description
