Description

Technical Field

[0001] This utility model relates to a wall coating device for high-altitude operations, belonging to the field of construction equipment technology. Background Technology

[0002] Currently, painting work on high-altitude building walls mainly relies on manual labor. Operators typically need to stand on high-altitude work platforms, elevators, or scaffolding, using rollers or brushes to apply the paint. Manual painting is inefficient and labor-intensive, especially when working on large areas of walls, which is time-consuming. Secondly, the quality of the work is highly dependent on the experience and skill level of the workers, making it difficult to guarantee the uniformity of the coating thickness and the smoothness of the surface. Furthermore, the high-altitude environment itself is dangerous. Working with arms outstretched or body leaning for extended periods not only easily leads to fatigue but also increases the risk of falls from heights. In addition, paint drips pollute the environment and pose safety hazards. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a wall coating device for high-altitude operations, which can effectively improve the efficiency of high-altitude wall coating operations.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a wall coating device for high-altitude operations, comprising: Fixed base; A movable bracket, which is mounted on the fixed base; The applicator includes two applicator brushes, a connecting seat, and two swing arms. The two applicator brushes are hinged to the connecting seat. The movable bracket has an elongated hole, and the connecting seat is slidably installed in the elongated hole. The two swing arms are installed on the top of the movable bracket, wherein one swing arm is hinged to any one of the applicator brushes, and the other swing arm is hinged to the other applicator brush. The sliding of the connecting seat along the elongated hole causes the two brushes to rotate around the hinge point between the brush and the connecting seat, thereby allowing the two brushes to swing towards or away from each other.

[0005] Furthermore, the brush includes an extension part and a fixing part. The fixing part has a first fixing hole at its top, the extension part has a hollow cavity, and the extension part has a plurality of evenly distributed second fixing holes. The extension portion is sleeved on the fixing portion through the hollow cavity, and the fixing portion is adapted to be hinged to the connecting seat. The first fixing hole and the second fixing hole have the same diameter.

[0006] Furthermore, a wall coating device for high-altitude operations also includes a fixing bolt, which is adapted to pass through the first fixing hole and any one of the second fixing holes simultaneously, so as to fix and lock the extension part and the fixing part at a selected length position.

[0007] Furthermore, a wall coating device for high-altitude operations also includes a movable drive component, the fixed end of which is mounted on the fixed base, and the movable end of which is connected to the connecting seat.

[0008] Furthermore, two clamping blocks are slidably installed at the bottom of the fixed base, the two clamping blocks are arranged opposite each other, and a clamping groove is provided between the two clamping blocks.

[0009] Furthermore, the clamping block is driven by at least one lead screw and nut pair, the lead screw and nut pair including a rotating lead screw rotatably mounted on the fixed base and a nut mounted on the clamping block, the rotating lead screw being connected to the nut; Turning the rotary screw is adapted to move the clamping block to adjust the size of the clamping groove.

[0010] Furthermore, an elastic anti-slip pad is provided on the opposite side of the two clamping blocks.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects: 1. In this utility model, the device is moved to a suitable position on the high-altitude work platform or scaffolding, and the rotating screw at the bottom of the fixed base is manually screwed. The two clamping blocks are driven to move towards each other through the screw nut pair. The device is firmly clamped to the platform railing or stable structure by using the clamping groove and the elastic anti-slip pad on its inner side. Depending on the specific width of the wall to be coated, the second fixing holes at different positions on the extension part are inserted through the fixing bolts and aligned with the first fixing hole of the fixing part to lock, thereby changing the extension length of a single brush. The movable drive is activated, and the connecting seat slides in the long waist hole to adjust the unfolding angle of the two brushes so that their brush surfaces just cover the width of the target wall. The paint is then evenly applied to the two brushes. The movable drive is controlled so that the connecting seat drives the two brushes to maintain the set unfolding angle, so that the two brush surfaces are in close contact with the wall for coating. During operation, the angle of the brush can be finely adjusted in real time according to changes in the wall structure. After the application is completed, the movable drive component is controlled to move the connecting seat down, bringing the two brushes together to their minimum width. The clamping mechanism is then released, and the device can be transferred to the next work point.

[0012] 2. In this utility model, the synchronous opening and closing of two brushes can be achieved by a single drive control, which can quickly, continuously and accurately adjust the working width. It can adapt to complex structures such as walls, inside and outside corners, and windows of different widths without changing tools, which greatly reduces the auxiliary adjustment time, expands the coverage area of ​​a single operation, and significantly improves construction efficiency. This device replaces the unstable and fatigue-prone reciprocating motion of a manual arm, ensuring a more uniform and stable contact pressure and movement trajectory between the brush and the wall during the coating process. This helps to achieve a consistent coating thickness and a smooth surface, improving project quality and reducing paint waste caused by uneven coating. Attached Figure Description
