Description

Technical Field

[0001] This utility model relates to the field of spray painting fixtures, and in particular to a spray painting fixture for aluminum single panels. Background Technology

[0002] Aluminum single-panel spraying racks are key equipment in the production of building decoration materials. They are used to suspend and transport aluminum single-panel panels during the spraying process. With the increasing demand for large curtain wall aluminum single-panel panels, higher requirements are placed on the load-bearing stability, height adjustment accuracy, and ease of operation of the racks. Efficient and reliable spraying racks directly affect the uniformity of the surface coating and production efficiency.

[0003] Currently, aluminum single-panel spraying lines generally use chain-type lifting racks or hydraulic positioning devices. The chain structure uses a motor to drive the chain to raise and lower the boom, and relies on an electromagnetic brake to achieve suspension. The hydraulic system uses a cylinder to lift the boom and uses a one-way valve to lock the oil circuit to maintain the height. Both require an external power source. When adjusting manually, threaded rods or pin holes are used for positioning. The screw is tightened against the fixed plate by rotating the handwheel, or a pin is inserted to limit the displacement of the boom.

[0004] The above structure has certain safety hazards. When suspending heavy aluminum panels, the threaded top rod is prone to loosening under vibration, and there is a risk of slippage in the positioning of the pin hole. Once it loosens and falls, it may cause minor damage to the coating or even cause the aluminum panel to fall. In particular, the inertial impact generated by the chain structure during emergency stops will aggravate the wear of the braking mechanism and further amplify the safety risks. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an aluminum single-panel spraying bracket, which aims to improve the problem of easy loosening of the spraying bracket when suspending heavy aluminum single panels.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aluminum single-panel spraying bracket, including a bracket, a lifting component is provided inside the bracket, a base is fixedly connected to the lower surface of the bracket, a pulley is rotatably connected to the lower surface of the base, a gantry is fixedly connected to the upper surface of the bracket, a hanging rod is provided below the gantry, and an adjustment component is provided inside the hanging rod;

[0007] The lifting assembly includes a reel, a gear, and a double-headed pawl. The outer wall of the reel is rotatably connected to the inner wall of the bracket. The gear is located inside the bracket. The outer wall of the double-headed pawl is rotatably connected to the inner wall of the bracket. The gear and the double-headed pawl are meshed together. A connecting line is provided on the outer wall of the reel. A crank is fixedly connected to the outer wall of the gear. The crank is located on the outer wall of the bracket.

[0008] Furthermore, the adjustment component includes a groove and a locking block. The groove is formed on the outer wall of the boom, the locking block is disposed inside the groove, a slider is slidably connected to the inner wall of the boom, a hook is fixedly connected to the inner wall of the slider, a pull rod is slidably connected to the inner wall of the hook, and the locking block is fixedly connected to the outer wall of the pull rod.

[0009] Furthermore, a roller is rotatably connected to the outer wall of the slider, and the outer wall of the roller is slidably connected to the inner wall of the boom.

[0010] Furthermore, a limiting plate is fixedly connected to the outer wall of the pull rod, the limiting plate is disposed inside the slider, and a spring is sleeved on the outer wall of the pull rod.

[0011] Furthermore, one end of the second spring is fixedly connected to the inner wall of the slider, and the other end of the second spring is fixedly connected to the outer wall of the limiting plate.

[0012] Furthermore, the gantry is equipped with multiple rollers, and the upper surface of the boom is rotatably connected to multiple rollers. The reel, rollers, and rollers are connected by a connecting line.

[0013] Furthermore, a sliding rod is fixedly connected to the outer wall of the double-headed pawl, and the sliding rod is disposed in an arc-shaped slot that penetrates through the outer wall of the bracket.

[0014] Furthermore, a spring is provided inside the bracket, with one end of the spring fixedly connected to the inner wall of the bracket and the other end of the spring fixedly connected to the outer wall of the double-headed pawl.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the lifting assembly achieves smooth lifting and lowering of the boom. During operation, rotating the crank handle drives the gear to rotate, and the double-headed pawl achieves one-way self-locking of the gear. At the same time, the reel synchronously retracts and extends the connecting line to control the height of the boom. This design only requires one-handed operation for precise positioning. The pawl mechanism automatically locks the load at any position, and the spring continuously provides reverse resistance, effectively preventing the boom from accidentally sliding down and ensuring that the aluminum panel is stably suspended during the spraying process.

[0017] 2. In this utility model, the hook spacing is adjusted by adjusting the adjustment component. When moving the slider horizontally, the pull rod is pulled outward to make the locking block disengage from the groove. After the slider is gently pushed to the target position by the roller, the pull rod is released. The spring pushes the locking block to automatically lock into the corresponding groove to complete the fixation. No tools are required throughout the process, and the operation can be completed with one hand. The roller reduces the frictional resistance of the slider, realizes precise adjustment, and adapts to the suspension requirements of aluminum panels of different sizes. Attached Figure Description
