[0001] This utility model relates to the field of elevator guide rail maintenance technology, and in particular to an elevator guide rail painting device. Background Technology

[0002] During elevator operation, the elevator guide rail plays a crucial role, and its surface condition directly affects the safety and stability of elevator operation. To prevent corrosion and wear due to long-term use, the guide rail needs to be coated with protective paint.

[0003] In existing technologies, elevator guide rail painting largely relies on manual operation, which is not only inefficient but also difficult to precisely control the painting position and angle, resulting in inconsistent painting quality. Manual painting also presents high safety risks and labor intensity. Therefore, this paper proposes an elevator guide rail painting device that can achieve automated painting while ensuring painting accuracy and quality. Utility Model Content

[0014] The elevator guide rail painting device of this utility model will be further described below with reference to the accompanying drawings.

[0015] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixing" should be used in a broad sense. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] See Figure 1-4 As shown in the figure, an elevator guide rail painting device in this embodiment includes a lifting wheel clamp 1, an L-shaped bracket 2 fixedly installed on the upper end of the lifting wheel clamp 1, a V-shaped bending strip 3 fixedly installed on the upper end of the L-shaped bracket 2, and a paint spray nozzle 4 fixedly installed in the through holes at both ends of the V-shaped bending strip 3.

[0018] Specifically, the L-shaped bracket 2, V-shaped bending strip 3, and paint spray nozzle 4, in conjunction with the lifting wheel clamp 1, can automatically lift and lower itself on the T-shaped elevator guide rail to spray protective paint onto the surface of the T-shaped elevator guide rail, thus automating the guide rail painting process and ensuring accurate painting position and reasonable angle. The lifting wheel clamp 1 can be clamped on the outside of the T-shaped guide rail and can automatically lift and lower itself along the T-shaped elevator guide rail. It can be braked and fixed, and has an anti-slip function. It has high horizontal and vertical friction, is anti-slip and stable, and the lifting wheel clamp 1 is stable in lifting and lowering and is not easy to slip off. The L-shaped bracket 2 and V-shaped bending strip 3 are responsible for supporting the paint spray nozzle 4, providing an installation base for the paint spray nozzle 4, fixing the position and tilt angle of the paint spray nozzle 4, and ensuring that the paint spray nozzle 4 can accurately spray protective paint onto the outside of the elevator guide rail. The hose at the rear end of the paint spray nozzle 4 is connected to the paint storage and supply system used in conjunction with it. The paint spray nozzle 4 is responsible for spraying protective paint onto the outside of the elevator guide rail and is the key component for realizing the painting of the elevator guide rail, directly completing the painting operation on the guide rail surface.

[0019] See appendix Figure 1-4As shown, the lifting wheel clamp 1 includes a first plate 101, a second plate 102 slidably mounted on the first plate 101, a telescopic short rod 103 elastically connected between the first plate 101 and the second plate 102, a first fixed shaft 104 fixedly mounted in a notch on one side of the first plate 101 and the second plate 102, a first rubber wheel 105 rotatably mounted on the first fixed shaft 104, a motor outer frame 106 fixedly mounted in the middle of the first plate 101, a first motor 107 fixedly mounted in the motor outer frame 106, and a fixed mounting bracket. The components include a second rubber wheel 108 mounted at the front end of the rotating shaft of motor 107, a second fixed shaft 109 fixedly installed in the through hole of plate 102, a third rubber wheel 110 rotatably sleeved on the second fixed shaft 109, a threaded pin 111 penetrating the threaded through hole of plate 102, a limiting slide frame 112 fixedly installed on the front surface of plate 102, a second motor 113 slidably installed in the limiting slide frame 112, and a limiting strip 114 fixed outside the second motor 113 and inserted into the slide groove of the limiting slide frame 112.

[0020] Specifically, the telescopic short rod 103 provides elastic force between plate 101 and plate 102, allowing the lifting wheel clamp 1 to be clamped onto the T-shaped elevator guide rail via the rubber wheel 105 on plate 101 and plate 102, thus connecting and installing the device to the guide rail. The rubber layer on the outside of rubber wheel 105, rubber wheel 108, and rubber wheel 110 increases the friction between the device and the guide rail, providing an anti-slip effect, ensuring the stability of the device on the guide rail, and preventing slippage.

[0021] See appendix Figure 1-3 As shown, the outer side of the first rubber wheel 105 is provided with multiple annular grooves evenly distributed, the outer side of the second rubber wheel 108 is provided with multiple transverse grooves evenly distributed, and the outer side of the third rubber wheel 110 is provided with multiple transverse grooves evenly distributed.

[0022] Specifically, the annular groove on the outer side of the first rubber wheel 105 increases the lateral friction between the device and the guide rail; the lateral grooves on the second rubber wheel 108 and the third rubber wheel 110 provide the vertical friction between the device and the guide rail.

[0023] See appendix Figure 1-3 As shown, the first motor 107 drives the second rubber wheel 108 to rotate, and the front end of the rotating shaft of the third rubber wheel 110 is fixedly connected to the rear end of the threaded pin 111. The third rubber wheel 110 drives the threaded pin 111 to rotate.

[0024] Specifically, the first motor 107 drives the second rubber wheel 108 to rotate, which in turn drives the device to move up and down along the T-shaped elevator guide rail, enabling the device to move along the guide rail and perform painting operations at different positions on the guide rail. The first rubber wheel 105 and the third rubber wheel 110 then move along the side of the T-shaped elevator guide rail.

[0025] See appendix Figure 1-4 As shown, multiple limiting through holes are evenly distributed inside the No. 3 rubber wheel 110, and the front end of the threaded pin 111 is inserted into the through hole of the No. 3 rubber wheel 110.

[0026] Specifically, the threaded pin 111 is rotated by the second motor 113, which causes the threaded pin 111 to be pulled out and inserted into the through hole of the third rubber wheel 110, thereby achieving the braking and fixing of the device. This makes it convenient to fix the position of the device when needed. The second motor 113 then slides along the limit slide frame 112, and the limit strip 114 prevents the second motor 113 from rotating.

[0027] See appendix Figure 1-2 As shown, a flexible hose is connected to the rear end of the paint spray nozzle 4; the flexible hose at the rear end of the paint spray nozzle 4 is connected to the paint storage and supply system used in conjunction with it.

[0028] When operating this utility model: During installation, the lifting wheel clamp 1 is clamped to the outside of the T-shaped elevator guide rail by the first rubber wheel 105, and the telescopic short rod 103 provides elastic force to ensure that the guide rail is clamped, thus completing the connection and installation of the device and the guide rail. When connecting the paint, connect the hose at the rear end of the paint nozzle 4 to the paint storage and supply system to prepare for the painting operation; When the device is moved, start motor 107 to drive rubber wheel 108 to rotate, which will drive the device to rise and fall along the T-shaped elevator rail. At the same time, rubber wheel 105 and rubber wheel 110 move along the side of the T-shaped elevator rail to move the device to the position of the T-shaped elevator rail that needs to be painted. When fixing the device, once the device reaches the appropriate position, start the second motor 113 to drive the threaded pin 111 to rotate, so that the threaded pin 111 is inserted into the limiting through hole of the third rubber wheel 110, thereby braking and fixing the device to ensure the stability of the device during the painting process. When painting begins, the paint storage and supply system is turned on, and the paint is delivered to the spray nozzle 4 through the hose. The spray nozzle 4 sprays protective paint onto the outside of the elevator guide rail. Since the L-shaped bracket 2 and the V-shaped bending strip 3 fix the position and tilt angle of the spray nozzle 4, the paint can be accurately sprayed onto the surface of the guide rail. During continuous painting, motor 107 is continuously started, driving the device to move continuously along the guide rail to paint the T-shaped elevator guide rail. When painting stops, turn off motor 107 and start motor 113 to brake the device and fix its position. After painting is completed, turn off the paint storage and supply system, disconnect the hose at the rear end of the paint nozzle 4 from the paint storage and supply system, remove the device from the guide rail and store it properly.

[0029] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
