Technical Field
[0001] This utility model relates to the field of painting device technology, and in particular to a painting device for exterior walls of buildings undergoing renovation. Background Technology
[0002] Building exterior walls provide a sturdy barrier to the interior space of a building, resisting the influence of various natural environmental factors. They can block the invasion of wind, rain, snow, ultraviolet rays, etc., and prevent moisture from seeping into the building. However, over time, building exterior walls may experience problems such as aging, fading, and damage, requiring renovation and reconstruction. Exterior wall painting equipment is a commonly used device in building exterior wall renovation work.
[0003] Existing painting devices often use cable structures to lift the paint roller up and down during operation. However, if the cable lifting structure is damaged or breaks, the paint roller will fall instantly, which will not only damage the device but also threaten the safety of the workers below.
[0004] Therefore, a building exterior wall painting device was proposed, which solved the problem of the paint roller falling instantly after the cable lifting structure broke, affecting the safety of the construction workers below. Utility Model Content
[0005] To address the problem that painting devices often rely on cable structures to lift the painting rollers up and down during operation, but if the cable lifting structure is damaged or breaks, the painting rollers will fall instantly, damaging the device and threatening the safety of workers below, a new building exterior wall painting device is proposed.
[0006] The technical solution of this utility model is as follows: a building renovation exterior wall painting device, comprising a movable installation base plate and support frame, a sliding groove, a locking block, a paint transfer box, an emergency safety locking component, a uniform painting component, an electric winch, a cable, a hook, and an elastic guide belt; the upper end of the movable installation base plate is fixedly connected to the support frame; a sliding groove is provided on the side end of the support frame; a locking block is slidably connected inside the sliding groove; a paint transfer box is fixedly connected to the side end of the sliding block; an emergency safety locking component is provided at the lower end of the paint transfer box; a uniform painting component is provided at the side end of the paint transfer box; an electric winch is installed at the upper end of the support frame; a cable is wound around the outer end of the output end of the electric winch; a hook is fixedly connected to the lower end of the cable; the lower end of the hook is fixedly connected to the top of the paint transfer box; an elastic guide belt is fixedly connected between the lower end of the support frame and the upper end of the movable installation base plate; the emergency safety locking component includes a hollow cylinder and a flow channel; a hollow cylinder is fixedly connected to the lower end of the paint transfer box; a flow channel is provided on the side end of the hollow cylinder; the elastic guide belt is slidably connected to the inside of the flow channel.
[0007] Preferably, during the use of the painting device, the hollow cylinder in the emergency safety locking assembly slides outside the elastic guide belt. When the paint transfer box loses the lifting force of the cable and falls rapidly, the bidirectional hydraulic cylinder pushes the extrusion plate to squeeze the elastic guide belt inside the hollow cylinder. This, combined with the anti-slip friction plate, provides rapid deceleration, preventing the paint transfer box connected above the hollow cylinder from falling rapidly and achieving an emergency stop. Meanwhile, the motor in the uniform painting assembly drives the stirring paddle to continuously agitate the paint storage tank, maintaining the uniformity of the paint in the tank and preventing paint stratification that would lead to uneven painting. The feeding pump inputs the paint from the paint storage tank into the paint transfer box, which is then sprayed out from the nozzle, ensuring that the paint adheres evenly to the surface of the brush roller, thus enabling uniform painting of the wall surface.
[0008] As a preferred embodiment, the emergency safety locking assembly also includes an anti-slip friction plate, a two-way hydraulic cylinder, a limit baffle, a compression plate, and a return spring; the inner wall of the hollow cylinder is equipped with an anti-slip friction plate.
[0009] Preferably, a bidirectional hydraulic cylinder is installed inside the hollow cylinder; a limit baffle is installed inside the hollow cylinder; the output end of the bidirectional hydraulic cylinder passes through the limit baffle and is connected to two extrusion plates; a return spring is fixed between the two extrusion plates.
[0010] Preferably, the uniform coating assembly includes a paint storage tank, a motor, a transmission rod, a stirring paddle, a feeding pump body, a nozzle, a brush roller, a sliding roller, and a counterweight; the paint storage tank is installed at the upper end of the movable mounting base; the motor is installed at the upper end of the paint storage tank; the output shaft of the motor passes through the paint storage tank and is fixedly connected to the transmission rod.
[0011] Preferably, the lower end of the transmission rod is fixedly connected to a stirring paddle; the discharge port pipe of the paint storage tank is connected to the input end of the feeding pump body.
[0012] Preferably, the output pipe of the feeding pump body is connected to the inside of the paint transfer box; a nozzle is provided on the side end of the paint transfer box; and a brush roller is rotatably connected to the side end of the paint transfer box.
[0013] Preferably, sliding rollers are rotatably connected to both sides of the paint transfer box; the sliding rollers are slidably connected to the elastic guide belt; and a counterweight is installed at the upper end of the paint transfer box.
[0014] The beneficial effects of this utility model are:
[0015] During the use of the coating device, the hollow cylinder slides outside the elastic guide belt. When the paint transfer box loses the lifting force of the cable and falls rapidly, the bidirectional hydraulic cylinder pushes the extrusion plate to squeeze the elastic guide belt inside the hollow cylinder. In conjunction with the anti-slip friction plate, it can quickly decelerate the paint transfer box connected to the top of the hollow cylinder, preventing it from falling rapidly and achieving an emergency stop effect, thereby improving the safety of the device during construction operations.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The system includes a uniform coating assembly; an electric winch 6 is installed at the upper end of the support frame 2; a cable 7 is wound around the outer end of the output end of the electric winch 6; a hook 8 is fixedly connected to the lower end of the cable 7; the lower end of the hook 8 is fixedly connected to the top of the paint transfer box 5; an elastic guide belt 9 is fixedly connected between the lower end of the support frame 2 and the upper end of the movable mounting base plate 1; the emergency safety locking assembly includes a hollow cylinder 201 and a flow channel 202; the hollow cylinder 201 is fixedly connected to the lower end of the paint transfer box 5; a flow channel 202 is opened on the side end of the hollow cylinder 201; the elastic guide belt 9 is slidably connected to the inside of the flow channel 202.
[0023] Please see Figure 2 In this embodiment, the emergency safety locking assembly further includes an anti-slip friction plate 203, a bidirectional hydraulic cylinder 204, a limiting baffle 205, a pressing plate 206, and a return spring 207. The inner wall of the hollow cylinder 201 is equipped with an anti-slip friction plate 203, and the inside of the hollow cylinder 201 is equipped with a bidirectional hydraulic cylinder 204. The inside of the hollow cylinder 201 is equipped with a limiting baffle 205. The output end of the bidirectional hydraulic cylinder 204 passes through the limiting baffle 205 and is connected to two pressing plates 206. A return spring 207 is fixed between the two pressing plates 206. The anti-slip friction plate 203, in conjunction with the pressing plates 206, can increase the friction force after pressing the elastic guide belt 9, so that the elastic guide belt 9 no longer passes through the hollow cylinder 201. The position of the hollow cylinder 201 is locked, thereby locking the paint transfer box 5 fixed above the hollow cylinder 201.
[0024] Please see Figure 4In this embodiment, the uniform coating assembly includes a paint storage tank 401, a motor 402, a transmission rod 403, a stirring paddle 404, a feeding pump body 405, a nozzle 406, a brush roller 407, a sliding roller 408, and a counterweight 409. The paint storage tank 401 is mounted on the upper end of the movable mounting base plate 1. The motor 402 is mounted on the upper end of the paint storage tank 401. The output shaft of the motor 402 passes through the paint storage tank 401 and is fixedly connected to the transmission rod 403. The lower end of the transmission rod 403... A stirring paddle 404 is fixedly connected to the paint storage tank 401; the outlet pipe of the paint storage tank 401 is connected to the input end of the feeding pump body 405, and the output end pipe of the feeding pump body 405 is connected to the inside of the paint transfer box 5; a spray nozzle 406 is provided on the side end of the paint transfer box 5; a brush roller 407 is rotatably connected to the side end of the paint transfer box 5, and sliding rollers 408 are rotatably connected to both sides of the paint transfer box 5; the sliding rollers 408 are slidably connected to the elastic guide belt 9; a counterweight 409 is installed on the upper end of the paint transfer box 5.
[0025] During operation, the electric winch 6 first raises and lowers the paint transfer box 5 below by raising and lowering the cable 7, thereby painting the wall. The hollow cylinder 201 below the paint transfer box 5 slides outside the elastic guide belt 9. When the paint transfer box 5 loses the lifting force of the cable 7 and falls rapidly, the bidirectional hydraulic cylinder 204 pushes the extrusion plate 206 to extrude the elastic guide belt 9 inside the hollow cylinder 201. With the help of the anti-slip friction plate 203, it can quickly decelerate the paint transfer box 5 connected above the hollow cylinder 201, so that it can stop the paint transfer box 5 from falling rapidly.
[0026] Then, the motor 402 drives the stirring paddle 404 to continuously stir in the paint storage tank 401, which can maintain the uniformity of the paint in the tank and avoid the paint from separating and causing unevenness after application.
[0027] Finally, the paint in the paint storage tank 401 is fed into the paint transfer box 5 by the feed pump body 405, and then sprayed out from the nozzle 406, so that the paint is evenly attached to the surface of the brush roller 407, thereby enabling the wall surface to be evenly coated.
[0028] Through the above steps, the problem of the paint roller 407 falling instantly after the lifting structure of cable 7 breaks and damages, affecting the safety of construction personnel below, is solved. By sliding the hollow cylinder 201 outside the elastic guide belt 9, when the paint transfer box 5 loses the lifting force of cable 7 and falls rapidly, the bidirectional hydraulic cylinder 204 pushes the extrusion plate 206 to extrude the elastic guide belt 9 passing through the hollow cylinder 201, and the anti-slip friction plate 203 plays a role in rapid deceleration, so that the paint transfer box 5 connected above the hollow cylinder 201 is no longer falling rapidly, achieving the effect of emergency stop.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
