Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] like Figures 1 to 7 As shown, a lifting spray bracket in one embodiment of the present invention includes: a frame 1, a lifting adjustment mechanism 2, and a balanced spray mechanism 3.

[0025] like Figure 1 As shown, multiple sets of evenly distributed wheels 4 are fixedly connected to the lower part of the frame 1. The multiple sets of wheels 4 provide support, limit, and assist movement for the frame 1, thereby improving the ease of movement of the frame 1.

[0026] Specifically, a pair of omnidirectional wheels are fitted on the side of the frame 1 that is close to the movable handrail 5. The omnidirectional wheels improve the convenience of multi-angle movement control of the frame 1.

[0027] like Figure 1 As shown, a movable handrail 5 is fixedly connected to the top of the frame 1, and the movable handrail 5 is arranged on one or both sides of the frame 1. The movement of the frame 1 is controlled by applying force to the movable handrail 5.

[0028] like Figures 4 to 5 As shown, the lifting and adjusting mechanism 2 is fixedly mounted on the top of the frame 1. The lifting and adjusting mechanism 2 includes a column 201, which is fixedly mounted on the top of the frame 1. The column 201 serves to store, support, and guide the lifting of the retractable column 202.

[0029] like Figures 1 to 2 As shown, a retractable column 202 is slidably assembled inside the column 201. The retractable column 202 supports and fixes the limiting support 203, and the balance spray mechanism 3 is synchronously raised and lowered by controlling the raising and lowering of the retractable column 202.

[0030] Specifically, the height adjustment range of the upright 201 and the retractable upright 202 is 3 to 4 meters.

[0031] like Figure 4 As shown, a limiting support 203 is fixedly connected to one end of the retractable column 202 outside the column 201. The operating rod 301 is hinged and limited by the limiting support 203, so the high-pressure water gun 6 can be adjusted to different angles by rotating the operating rod 301 around the limiting support 203.

[0032] like Figures 4 to 5 As shown, a pair of hydraulic lifting rods 204 are fixedly connected to the top of the frame 1, and the pair of hydraulic lifting rods 204 are symmetrically arranged on both sides of the column 201. By controlling the extension and retraction of the telescopic ends of the pair of hydraulic lifting rods 204, auxiliary support and lifting control of the retractable column 202 can be provided.

[0033] Preferably, the hydraulic lifting rod 204 has a size of φ50×1500, and there are 2 sets available. It is commercially available and can be purchased and used directly.

[0034] In addition, a 3L hydraulic oil pump and control box can be installed on the frame 1. The hydraulic oil pump and control box can be used to control the extension and retraction of the extension end of the hydraulic lifting rod 204.

[0035] like Figures 4 to 5 As shown, each pair of hydraulic lifting rods 204 is fixedly connected to the column 201 by symmetrically distributed fixing brackets 205. The hydraulic lifting rods 204 are assembled and fixed by multiple sets of fixing brackets 205.

[0036] like Figure 4 As shown, each of the telescopic ends of a pair of hydraulic lifting rods 204 is hinged with a lifting limit pin 206, which is fixedly connected to the side wall of the retractable column 202. The lifting limit pin 206 serves to connect the telescopic ends of the hydraulic lifting rods 204 and the retractable column 202, allowing the retractable column 202 to move synchronously up and down with the extension and retraction of the telescopic ends of the hydraulic lifting rods 204 under the action of the lifting limit pin 206.

[0037] like Figure 1 As shown, the balance injection mechanism 3 is hingedly mounted on the upper part of the frame 1. The balance injection mechanism 3 includes an operating lever 301, which is hingedly mounted on the upper part of the limiting support 203. The operating lever 301 serves to limit the assembly of the rear operating lever 305 and the first extension lever 302.

[0038] The operating lever 301 is fixedly connected to horizontal wing frames on both the left and right sides, which improves the horizontal balance performance of the operating lever 301.

[0039] like Figures 1 to 2 As shown, a first extension rod 302, a second extension rod 303, and a third extension rod 304 are sequentially slidably inserted into one end of the operating lever 301. The length of the movable handle 5 can be adjusted by extending and retracting the first extension rod 302, the second extension rod 303, and the third extension rod 304, thereby increasing the range of rust removal and painting performed by the high-pressure water gun 6.

[0040] In addition, a rotatable gooseneck head can be installed between the third extension rod 304 and the high-pressure water gun 6, so that the high-pressure water gun 6 can swing in all directions, up and down and left and right, improving the rinsing flexibility of the high-pressure water gun 6.

[0041] Preferably, the adjustable size range of the operating lever 301, the first extension lever 302, the second extension lever 303 and the third extension lever 304 is 12 to 25 meters.

[0042] Specifically, the operating lever 301 has a first storage groove on the side close to the first extension rod 302, the first extension rod 302 is slidably fitted in the first storage groove, the first extension rod 302 has a second storage groove, the second extension rod 303 is slidably fitted in the second storage groove, the second extension rod 303 has a third storage groove, and the third extension rod 304 is slidably fitted in the third storage groove.

[0043] like Figures 4 to 6 As shown, limiting springs 308 are evenly distributed in the first, second, and third storage grooves. The limiting springs 308 support and reset the first extension rod 302, second extension rod 303, and third extension rod 304 respectively, reducing the possibility of retraction under external force and ensuring the reliability of extending the first extension rod 302, second extension rod 303, and third extension rod 304.

[0044] like Figures 2 to 4 As shown, a rear operating lever 305 is fixedly connected to the other end of the operating lever 301. The rear operating lever 305 serves to support and fix the control box frame 311 and the control handle 316.

[0045] like Figures 2 to 4 As shown, several sets of winches 306 are rotatably connected above the rear operating lever 305. The rotation of the winches 306 can control the winding of the pull rope 307, thereby controlling the pulling limit state of the pull rope 307 on the first extension rod 302, the second extension rod 303 and the third extension rod 304.

[0046] like Figures 2 to 4 As shown, several sets of winches 306 are each fitted with a pull rope 307 on their outer sides, and the other end of the pull ropes 307 is fixedly connected to the first extension rod 302, the second extension rod 303, and the third extension rod 304, respectively. The pull ropes 307 are used to pull and limit the first extension rod 302, the second extension rod 303, and the third extension rod 304.

[0047] Specifically, the pull rope 307 is a steel wire rope, which can be purchased and used directly. By cooperating with the winch 306 to form a cable structure, the front-to-back stability of the operating rod 301 can be improved.

[0048] like Figures 4 to 6 As shown, the ends of the first extension rod 302, the second extension rod 303, and the third extension rod 304 away from the operating rod 301 are all fixedly connected to a traction seat 309. The traction seat 309 serves to limit the assembly of the traction limiting wheel 310.

[0049] like Figures 4 to 6 As shown, each of the multiple traction seats 309 is rotatably equipped with a traction limiting wheel 310, and several traction ropes 307 are fixedly connected to each of the multiple traction seats 309. The traction limiting wheel 310 serves to connect and limit the traction ropes 307, thereby allowing the traction ropes 307 to provide auxiliary support and limit the first extension rod 302, the second extension rod 303, and the third extension rod 304 respectively by pulling and fixing the traction limiting wheel 310.

[0050] like Figures 2 to 3 As shown, multiple control box frames 311 are fixedly connected above the rear operating lever 305. The control box frames 311 provide assembly and limiting for the drive shaft 312.

[0051] like Figures 2 to 3 As shown, each of the several sets of winches 306 has a drive shaft 312 fixedly connected inside. Both ends of the drive shaft 312 are rotatably connected to the control box frame 311. The drive shaft 312 serves to limit the assembly and drive the rotation of the winch 306. By controlling the rotation of the drive shaft 312, the winch 306 is driven to rotate, thereby regulating the contraction and extension state of the traction rope 307.

[0052] like Figures 2 to 3 As shown, a worm gear 313 is fixedly connected to one end of the drive shaft 312 located outside the control box frame 311. A worm 314 meshes below the worm gear 313, and the worm 314 is rotatably connected to the control box frame 311. The rotation of the drive shaft 312 can be controlled by the cooperation of the worm gear 313 and the worm 314.

[0053] Specifically, the lead angle of the worm 314 is smaller than the equivalent friction angle of the worm wheel 313.

[0054] like Figures 2 to 3 As shown, a handwheel 315 is fixedly connected to one end of the worm gear 314 located outside the control box frame 311. The worm gear 314 is driven to rotate by rotating the handwheel 315.

[0055] like Figures 2 to 3 As shown, a control handle 316 is fixedly connected to the end of the rear operating lever 305 away from the operating lever 301. The rear operating lever 305 is pulled and supported by supporting the control handle 316.

[0056] like Figures 2 to 3As shown, a storage rack 317 is fixedly connected to the lower part of the rear operating lever 305. The storage rack 317 serves to store and limit the counterweight 318. Several counterweights 318 are arranged inside the storage rack 317. The counterweights 318 act as counterweights for the rear operating lever 305, improving the tilt control stability of the rear operating lever 305.

[0057] The number of counterweights 318 is 8 to 10, and the weight of each counterweight 318 is 3 kg.

[0058] like Figure 4 As shown, a guide column 319 is fixedly connected above the operating lever 301. Multiple guide rollers 320 are rotatably mounted inside the guide column 319, and these guide rollers 320 are configured to cooperate with the pulling ropes 307. The cooperation between the guide column 319 and the multiple guide rollers 320 allows for the support and limiting of several pulling ropes 307.

[0059] like Figure 7 As shown, a high-pressure water rust removal and painting equipment includes an adjustment mechanism and a high-pressure water gun 6, which is fixedly mounted on the end of the third extension rod 304 located outside the second extension rod 303.

[0060] In addition, the high-pressure water gun 6 is a 50Kg water spray gun with a length of 1.2m and a pipe diameter of 12mm.

[0061] In practical use, the frame 1 can be moved to the corresponding position by moving multiple sets of walking wheels 4 as needed. Furthermore, the lifting state of the retractable column 202 can be controlled by extending or retracting the extension end of the hydraulic lifting rod 204, thereby adjusting the horizontal height of the balance spray mechanism 3.

[0062] Meanwhile, the angle of the operating lever 301 can be adjusted by rotating the operating lever 301 around the limiting support 203. After the adjustment is completed, the operating lever 301 can be tilted and limited by arranging different numbers of counterweights 318 in the storage rack 317.

[0063] Furthermore, by controlling the rotation of the handwheel 315, the drive shaft 312 can be rotated synchronously under the cooperation of the worm gear 313 and worm 314. The rotation of the drive shaft 312 drives the winch 306 to rotate. First, by rotating clockwise, the pulling rope 307 wound on the outside of the winch 306 can be released, thereby allowing the first extension rod 302, the second extension rod 303, or the third extension rod 304 to extend and pop out under the action of the limit spring 308. When the first extension rod 302... After the second extension rod 303 or the third extension rod 304 extends to the specified length, the winch 306 can be driven to rotate by rotating the handwheel 315 counterclockwise, thereby winding and tensioning the pull rope 307. Through the cooperation of the pull rope 307 with the traction limit wheel 310 and the traction seat 309, the first extension rod 302, the second extension rod 303 or the third extension rod 304 can be pulled, limited and positioned. After adjustment, the flushing liquid or paint liquid can be delivered to the high-pressure water gun 6 for high-pressure water rust removal and painting treatment.

[0064] In addition, the entire structure adopts a detachable design, with component lengths within 3 meters, enabling integrated packaging and manual lifting, meeting the requirements for disassembly and assembly without a crane.
