Description

Technical Field

[0001] This invention relates to the field of painting equipment technology, and in particular to a forklift mast painting device. Background Technology

[0002] The forklift mast is the main load-bearing structure of the forklift's lifting device and the mechanism for lifting goods. It is also called the mast and consists of the inner mast, outer mast, fork carriage, forks, sprockets, chains, lifting cylinders, and tilting cylinders. To prevent the forklift mast from rusting, it needs to be painted.

[0003] Patent No. 202120098956.5 discloses a painting device for a forklift mast, which allows the forklift mast to automatically change its position for easier painting. A servo bidirectional motor controls the rotation of a lead screw, which drives a moving seat to move the spray gun along a slide bar. Once the desired position is reached, the button is released, thus improving the efficiency of forklift mast painting and reducing the labor intensity of manual painting requiring multiple adjustments to the forklift mast angle. However, in practice, this solution requires constant repositioning of the forklift mast, necessitating multiple operations by the operator, which reduces the painting efficiency and results in poor performance.

[0017] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0018] Please see Figure 1-9 The present invention provides a technical solution: a forklift mast painting device, including a housing 1, a hydraulic cylinder 2 fixedly connected to the inner wall of the housing 1, a fixing plate 5 fixedly connected to the output end of the hydraulic cylinder 2, and two insert rods 4 fixedly connected to the surface of the fixing plate 5. The two insert rods 4 are configured to be inserted into the interior of the channel steel on the forklift mast, thereby fixing the forklift mast in the device.

[0019] Two guide rods 3 are fixedly connected to the inner wall of the housing 1. The surfaces of the two guide rods 3 are slidably connected to the inside of the fixed plate 5 to guide the lifting and lowering of the fixed plate 5.

[0020] A U-shaped groove 8 is provided on the top of the housing 1. A moving mechanism 6 is provided on the inner wall of the U-shaped groove 8. A painting mechanism 7 is provided on the top of the housing 1. The painting mechanism 7 includes a fixed block 712. A rotating rod 10 is rotatably connected to the surface of the fixed block 712. The surface of the rotating rod 10 is slidably connected to the inner wall of the U-shaped groove 8. A limiting groove 12 is provided on the inner wall of the U-shaped groove 8. A roller 11 is fixedly connected to one end of the rotating rod 10 inside the U-shaped groove 8. The surface of the roller 11 is slidably connected to the inner wall of the limiting groove 12. Thus, the setting of the roller 11 and the limiting groove 12 avoids the separation between the fixed block 712 and the housing 1, thereby ensuring the smooth operation of the device.

[0021] The surface of the fixed block 712 is provided with a through groove 713, which provides passage space for the forklift mast. The inner wall of the through groove 713 is fixedly connected with a stop rod 714. The insertion depth of the forklift mast is limited by the setting of the stop rod 714, thereby avoiding the forklift mast from being in close contact with the fixed block 712, which would affect the U-shaped movement of the fixed block 712 later, and thus ensuring the smooth operation of the device.

[0022] A paint can 701 is fixedly connected to the top of the housing 1. A discharge pipe 702 is rotatably connected to the surface of the paint can 701. A conveying pipe 704 is fixedly connected to the surface of the fixed block 712. A corrugated pipe 703 is fixedly connected between the conveying pipe 704 and the discharge pipe 702. Thus, by setting the corrugated pipe 703, the paint can 701 can always convey to the fixed block 712 when the fixed block 712 moves, thereby ensuring the smooth operation of the device.

[0023] A liquid storage ring 705 is rotatably connected inside the fixed block 712. The liquid storage ring 705 is open, so it will not affect the insertion of the forklift mast. A movable groove 708 is formed on the surface of the liquid storage ring 705. The surface of the conveying pipe 704 is slidably connected to the inner wall of the movable groove 708. An arc-shaped baffle 709 is fixedly connected to one end of the conveying pipe 704 inside the liquid storage ring 705. The surface of the baffle 709 is slidably connected to the inside of the liquid storage ring 705. The baffle 709 can block the movable groove 708, thereby preventing paint leakage from the liquid storage ring 705. Sealing gaskets 715 are fixedly connected to both sides of the baffle 709. The surface of the sealing gasket 715 is slidably connected to the inside of the liquid storage ring 705. The sealing gasket 715 can fill the gap between the liquid storage ring 705 and the baffle 709, thereby preventing paint leakage and reducing paint waste.

[0024] Both sides of the inner wall of the liquid storage ring 705 are fixedly connected to the nozzles 706 that communicate with the liquid storage ring 705, for spraying paint on the surface of the forklift mast.

[0025] A worm gear 707 is fixedly connected to the surface of the liquid storage ring 705. The surface of the worm gear 707 is rotatably connected to the interior of the fixed block 712. A worm 710 protruding from the surface of the fixed block 712 is rotatably connected to the interior of the fixed block 712. The surface of the worm 710 is meshed with the surface of the worm gear 707.

[0026] The worm gear 710 protrudes from the surface of the fixed block 712 and is rotatably connected to two vertically arranged steering gears 711. The surface of the fixed plate 5 is fixedly connected to two steering racks 9. The two steering racks 9 are located on one side of the two insert rods 4 respectively, and the two steering racks 9 are also vertically arranged. The two steering racks 9 can mesh with the two steering gears 711 respectively.

[0027] The inner walls of the two steering gears 711 are slidably connected to slide rods 717, and the surfaces of the two slide rods 717 are fixedly connected to springs 716. The ends of the two springs 716 away from the slide rods 717 are respectively fixedly connected to the inside of the two steering gears 711 to reset the slide rods 717. The surface of the worm gear 710 is provided with two sets of circumferentially equidistant extrusion grooves 718. The cross-section of the extrusion grooves 718 is a right-angled triangle. The surfaces of the two slide rods 717 are slidably connected to the inner walls of the two sets of extrusion grooves 718 respectively.

[0028] The moving mechanism 6 includes two support rods 603, the surfaces of which are slidably connected to the top of the housing 1. The ends of the two support rods 603 away from the housing 1 are rotatably connected to the mounting plate 602. The surface of the conveying pipe 704 passes through the surface of the mounting plate 602 and is fixedly connected to the interior of the mounting plate 602, so that the mounting plate 602 can smoothly drive the conveying pipe 704 to move when it moves, thereby ensuring the smooth operation of the device.

[0029] A bidirectional motor 601 is fixedly connected to the surface of the mounting plate 602 to provide a power source for the operation of the device. The output end of the bidirectional motor 601 passes through the surface of the mounting plate 602 and is slidably connected to the inner wall of the U-shaped groove 8. The output end of the bidirectional motor 601 is rotatably connected to the surface of the fixed block 712. A moving gear 604 is slidably connected to the inner wall of the U-shaped groove 8. The output end of the bidirectional motor 601 is fixedly connected to the inner wall of the moving gear 604. A U-shaped moving rack 605 is fixedly connected to the inner wall of the U-shaped groove 8. The surface of the moving rack 605 meshes with the surface of the moving gear 604.

[0030] Furthermore, when painting the forklift mast, insert the two insert rods 4 into each side of the forklift mast, then activate the hydraulic cylinder 2 to gradually raise the fixing plate 5, thereby inserting the forklift mast into the through groove 713 on the fixing block 712. Then, the operator can start the bidirectional motor 601 and simultaneously start the liquid pump in the paint tank 701 to allow the paint to enter the discharge pipe 702. As the bidirectional motor 601 starts, it drives the moving gear 604 to rotate. Since the moving rack 605 is meshed with the moving gear 604, the moving gear 604 rotates and slides in the U-shaped groove 8, thereby causing the bidirectional motor 601 to make a U-shaped movement. This allows the fixing block 712 to move along the trajectory of the forklift mast. After entering the discharge pipe 702, the paint enters the liquid storage ring 705 through the corrugated pipe 703 and the conveying pipe 704, and then sprays the surface of the forklift mast through the spray nozzle 706.

[0031] As the fixed block 712 moves, the steering gear 711 comes into contact with the steering rack 9, causing the steering gear 711 to rotate through meshing. This causes the surface of the slide rod 717 to press against the vertical edge of the extrusion groove 718, pushing the worm gear 710 to rotate with the steering gear 711. This, in turn, causes the worm wheel 707 to rotate through meshing, causing the liquid storage ring 705 to rotate along with the two nozzles 706. Due to the limited length of the steering rack 9, it can only rotate the liquid storage ring 705 by 90 degrees, allowing the nozzles 706 to begin spraying paint on the other two sides of the forklift mast. When the moving gear 604 moves to the end of the U-shaped groove 8, the bidirectional motor 601 begins to rotate in the opposite direction, causing the device to move in the opposite direction. At this time, the steering rack 9 again drives the steering gear 711 to rotate. The slide rod 717 then moves along the inclined surface of the extrusion groove 718, allowing the inclined surface of the extrusion groove 718 to press against the slide rod 717. The compression mechanism causes the slide bar 717 to gradually retract into the steering gear 711, compressing the spring 716. This prevents the steering gear 711 from driving the worm gear 710 to rotate, thus preventing the nozzle 706 from changing direction. This allows the nozzle 706 to smoothly paint the other two sides of the forklift mast, ensuring comprehensive painting of the forklift mast. Furthermore, the moving mechanism 6 and the painting mechanism 7 allow the device to complete the painting of the forklift mast with only one reciprocating movement of the bidirectional motor 601. Operators only need to change the forklift mast back and forth, making operation simpler and more convenient. This improves the painting efficiency of the forklift mast and has high promotional value. Simultaneously, the device paints along the trajectory of the forklift mast, ensuring comprehensive painting and improving the painting quality, avoiding secondary touch-ups, and further enhancing the device's effectiveness.

[0032] Furthermore, the change of rotation direction of the bidirectional electric motor 601 can be performed manually or controlled by a system. This is known to those skilled in the art, and existing technology can complete the reversal of the bidirectional motor 601, so it will not be discussed in detail here.

[0033] Working principle: When painting the forklift mast, the forklift mast is inserted into the through slot 713 on the fixing block 712. Then, the operator can start the bidirectional motor 601, simultaneously activating the liquid pump in the paint tank 701 to allow paint to enter the discharge pipe 702. This, in turn, moves the fixing block 712 along the trajectory of the forklift mast. After entering the discharge pipe 702, the paint passes through the corrugated pipe 703 and the conveying pipe 704 into the liquid storage ring 705, and is then sprayed onto the surface of the forklift mast through the spray nozzle 706. 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.
