Novel external wall painting machine

Abstract

The invention relates a novel external wall painting machine. The machine comprises a horizontal support placed at the top of a bearing column, wherein the horizontal support comprises a horizontallyplaced transverse beam and transverse plates arranged at the two ends of the transverse beam, a traction device is arranged in the middle of the transverse beam, a mounting frame is arranged below thetransverse plate, the traction device penetrates through the transverse plate to be fixedly connected with the mounting frame, and a guiding device in contact with the bearing column and a brushing device in contact with a wall are arranged outside the mounting frame. According to the machine, by means of the traction device, the mounting frame equipped with the brushing device is gradually lowered, a lowering speed of the brushing device is slowed down through cooperation of a ratchet and a pawl, manual brushing is not needed, and the brushing efficiency is improved. According to the machine, through cooperation of the horizontal support and the guiding device, an L-shaped plate tightly clamps and fixes a corner of the bearing column, grasping force between a strip-shaped protrusion outside a guide roller and the wall enables the whole guiding device to descend vertically but cannot ascend, and the brushing device is guaranteed not to shake left and right in a descending process.

Description

technical field [0001] The invention relates to the technical field of exterior wall painting, in particular to a novel exterior wall painting machine. Background technique [0002] In order to ensure the beauty and waterproofness of the exterior walls of the building, it is necessary to paint the exterior walls at the end of the building. At present, people are hung in the air by slings, and the exterior walls are painted. When painting the exterior walls in this way, several requirements must be met. Conditions: 1. It must be carried out under good weather conditions. Conditions such as strong wind, poor visibility and high temperature are not suitable for exterior wall painting; 2. High-altitude operators have strict requirements on age and physical condition; 3. Painting equipment It must be in good working condition. Since the rope strands need to be hoisted by workers, they should be replaced with new ropes immediately if the phenomenon of gradual cracking occurs. [...

[0002] In order to ensure the beauty and waterproof of the exterior wall of the building, it is necessary to paint the exterior wall at the end of the building. At present, people are hung in the air by a sling to paint the exterior wall. When painting the exterior wall in this way, several requirements must be met. Conditions: 1. It must be carried out under good weather conditions. Conditions such as strong wind, poor visibility and high temperature are not suitable for exterior wall painting; 2. High-altitude operators have strict requirements on age and physical condition; 3. Painting equipment It must be in good working condition. Since the rope strands need to hang workers, if there is a phenomenon of gradual cracking, replace it with a new rope immediately.

[0003] Although this method of painting works well, manual painting is relatively slow, and it takes a long time to paint once from top to bottom, and the workers stay on the hanging board for a long time; secondly, when manual painting, the hanging rope will Shaking back and forth with the person descending, there will be unevenness during the painting process, and at the same time, it is dangerous for workers
