Description

Technical Field

[0001] This utility model relates to a lifting platform, and more particularly to a spray painting lifting platform. Background Technology

[0002] Many auto parts manufacturers need to set up painting processes. Some painting processes are quite complex, resulting in long painting production lines that occupy a large area. Due to space constraints, some companies can only set up painting production lines on different floors. In this case, they need to install lifting platforms to transport the materials to be painted from the production line on the lower floor to the production line on the upper floor, serving as transfer devices between production lines on different floors.

[0003] Currently published patent documents disclose various lifting devices with different structures. For example, Chinese Patent 201911171981.5 discloses a lifting device and a painting robot. This lifting device includes a motor, a frame, and a lifting mounting base. A ball screw, chain, detection switch, and slide rail are vertically mounted on the front of the frame. This lifting device is mainly used to drive the painting robot up and down for painting work and is not suitable for material transfer on production lines on different floors. Chinese Patent 202211516455.X discloses a lifting platform for a painting booth, which includes a frame, a platform assembly, and a lifting drive assembly. This lifting platform is mainly used to lift painting workers for painting operations and is also not suitable for material transfer on production lines on different floors. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a spraying lifting platform with a reasonable structure and smooth movement, which can transfer the material to be sprayed on the production line on different floors, and is particularly suitable as a transfer device for production lines on different floors.

[0005] The technical solution to the above-mentioned technical problems is as follows: a spraying lifting platform, including a base, a counterweight, a bracket, a lifting assembly, a lateral movement assembly, and two support guide beams mounted on the base. The lifting assembly includes a lifting motor, a lifting gear set, and a lifting chain assembly. The lifting motor is mounted on the base. The lifting chain assembly consists of two lifting chains, which are driven by the lifting motor through the lifting gear set. The upper and lower ends of the two lifting chains are connected to the top and bottom ends of the bracket, respectively. The counterweight is fixed on the two lifting chains. The lateral movement assembly includes a lateral movement motor, a lateral movement gear set, and a lateral movement chain assembly mounted on the bracket. The lateral movement chain assembly consists of two sets of laterally arranged chains. Each set of chains includes at least one end-to-end loop chain. The two sets of chains are driven by the lateral movement motor through the lateral movement gear set.

[0006] Furthermore, the transverse moving gear set includes a drive gear, a driven gear, and two chain mounting shafts. The two chain mounting shafts are movably mounted on the bracket. Two sets of transverse chains are respectively mounted on the chain mounting shafts via sprockets. The drive gear is mounted on the transverse moving motor and is connected to the driven gear via a transmission chain. The driven gear is mounted on one of the chain mounting shafts.

[0007] Furthermore, the bracket includes a vertical frame, support rods connected to both sides of the bottom end of the vertical frame, and a chain mounting bracket mounted on the support rods. The chain mounting bracket is a hollow square frame with sprocket mounting grooves at both ends. The sprockets are placed in the sprocket mounting grooves, and the upper side plate of the chain mounting bracket is located in the middle of the ring chain.

[0008] Furthermore, the lifting gear set includes a drive shaft, driven shaft one, driven shaft two, driven shaft three, and two drive gears mounted on the drive shaft, two reversing gears one mounted on driven shaft one, two reversing gears two mounted on driven shaft two, and two reversing gears three mounted on driven shaft three. The drive shaft, driven shaft one, and driven shaft two are movably mounted on the base. Support frames are also installed at the top of the two support guide beams. The driven shaft three is mounted on the support frame. The lifting chain meshes with reversing gear one, drive gear, reversing gear two, and reversing gear three in sequence from the bottom to the top.

[0009] Furthermore, the cross-sectional shape of the two supporting guide beams is rhomboid, and the two supporting guide beams are arranged symmetrically.

[0010] Furthermore, guide components are installed on both sides of the counterweight balance block. The guide components consist of a V-shaped frame and two guide wheels respectively installed on the V-shaped frame. The V-shaped frame is fixed on the counterweight balance block, and the two guide wheels are in contact with the two inner surfaces of the support guide beam.

[0011] Furthermore, guide components two are installed on both sides of the bracket. The guide components two include a V-shaped frame two and two guide wheels two respectively installed on the V-shaped frame two. The V-shaped frame two is connected to the bracket through a connecting rod, and the two guide wheels two respectively contact the two outer surfaces of the support guide beam.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects:

[0013] 1. This utility model uses simple chains and gears as the main transmission components. A lifting assembly drives the bracket to move up and down, and a lateral movement component on the bracket can transport materials left or right to the conveyor lines of production lines on different floors. This utility model is particularly suitable for transferring materials between production lines on different floors. In production sites where spray painting lines are located on different floors due to space constraints, this utility model can transfer materials between different floors, connecting production lines on different floors into a complete production line, solving the problem that production enterprises cannot arrange long production lines due to limited space.

[0014] 2. This utility model is equipped with a counterweight balancing block that works with the bracket to maintain the dynamic balance of the entire platform. The counterweight balancing block moves in the opposite direction to the bracket. When the counterweight balancing block is located at the upper end of the support guide beam, the bracket is located at the lower end of the support guide beam. When the counterweight balancing block is located at the lower end of the support guide beam, the bracket is located at the upper end of the support guide beam, so that the entire platform is in a state of relative force balance.

[0026] A spray painting lifting platform, such as Figures 1-2 As shown, the platform includes a base 1, a counterweight 6, a bracket 9, a lifting assembly 2, a lateral movement assembly 8, and two support rail beams 4 mounted on the base. The lifting assembly 2 includes a lifting motor 22, a lifting gear set, and a lifting chain assembly. The lifting gear set is mounted on the base 1 and the support rail beams 4. The lifting motor 22 is mounted on the base 1. The lifting chain assembly consists of two lifting chains 27, which are driven by the lifting motor 22 through the lifting gear set. The upper and lower ends of the two lifting chains are connected to the top and bottom of the bracket 9, respectively, causing the bracket 9 to rise or fall. The counterweight 6 is fixed to the two lifting chains 27. The purpose of the counterweight 6 is to cooperate with the bracket 9 to maintain the dynamic balance of the entire platform. The counterweight 6 moves in the opposite direction to the bracket 9; when the bracket 9 rises, the counterweight 6 falls, and when the bracket 9 falls, the counterweight 6 rises. The lateral movement assembly 8 includes a lateral movement motor 82, a lateral movement gear set, and a lateral movement chain set mounted on the bracket 9. The lateral movement chain set consists of two sets of laterally arranged lateral chains 81. Each set of lateral chains includes two end-to-end connected loop chains. The two sets of lateral chains 81 are driven by the lateral movement motor 82 through the lateral movement gear set.

[0027] In this embodiment, the transverse moving gear set includes a drive gear, a driven gear, and two chain mounting shafts 83. The two chain mounting shafts 83 are movably mounted on the bracket 9. Two sets of transverse chains 81 are respectively mounted at both ends of the chain mounting shafts 83 via sprockets 85. The drive gear is mounted on the transverse moving motor 82 and is connected to the driven gear via a transmission chain 84. The driven gear is mounted on one of the chain mounting shafts 83. That is, the transverse moving motor 82 drives the two sets of transverse chains 81 to move through the drive gear, the driven gear, and the transmission chain 84, which can convey the material to be sprayed to the left or right in the horizontal direction.

[0028] In this embodiment, the bracket 9 includes a vertical frame 91, two support rods 92 connected to both sides of the bottom end of the vertical frame, and two chain mounting brackets 93 mounted on the support rods. Each chain mounting bracket 93 is a hollow square frame with sprocket mounting grooves at both ends. The sprockets 85 are located within these grooves. The upper side plate of the chain mounting bracket 92 is located in the middle of the annular chain, meaning the lower side of the annular chain passes through the square frame, and the upper side of the annular chain is located above the upper surface of the square frame (e.g., ...). Figures 3-4 As shown, the chain mounting bracket 92 provides some protection for the ring chain. Alternatively, the bracket can also employ other structures, as long as they facilitate the installation of the lateral movement component 8 and allow for easy lifting and lowering.

[0029] In this embodiment, the lifting gear set includes a drive shaft 23, a driven shaft 1 28, a driven shaft 26, a driven shaft 3 29, two drive gears 24 mounted on the drive shaft 23, two reversing gears 21 mounted on the driven shaft 1 28, two reversing gears 25 mounted on the driven shaft 26, and two reversing gears 210 mounted on the driven shaft 3 29. The drive shaft 23, driven shaft 1 28, and driven shaft 26 are movably mounted on the base 1. Support frames 7 are also installed at the top of the two supporting guide beams 4. Mounted on support frame 7, the lifting chain 27 meshes sequentially with reversing gear 1 21, driving gear 24, reversing gear 25, and reversing gear 3 210 from bottom to top. That is, the lifting chain 27 is divided into several chain segments arranged in different directions from bottom to top. These segments are arranged as follows: a lower vertical segment, a horizontal segment 1 after passing reversing gear 1 21, a horizontal segment 2 after passing driving gear 24 (located above horizontal segment 1), a middle vertical segment after passing reversing gear 25, and finally an upper vertical segment after passing reversing gear 3 210. The counterweight 6 is connected to the lifting chain 27 in the middle vertical segment. Driving gear 24 drives the lifting chain 27 to rise or fall, while reversing gears 1 21, 2 25, and 3 210 change the orientation of the lifting chain 27, enabling it to drive the counterweight 6 and support frame 9 to move in opposite directions.

[0030] In this embodiment, the cross-sectional shape of the two supporting guide beams 4 is rhomboid, and the sharp corners of the two supporting guide beams 4 are arranged symmetrically, that is, the four corners of the two supporting guide beams are located on the same straight line. Guide components 5 are installed on both sides of the counterweight 6. The guide components consist of a V-shaped frame 51 and two guide wheels 52 respectively mounted on the V-shaped frame 51. The V-shaped frame 51 is fixed to the counterweight 6, and the two guide wheels 52 respectively contact the two inner surfaces of the supporting guide beams 4. When the counterweight 6 moves up and down, the guide wheels 52 roll on the supporting guide beams 4, playing a guiding role and ensuring the stability of the movement of the counterweight 6. The bracket 9 is equipped with guide components 2 3 on both sides. The guide components 2 consist of a connecting rod 31, a V-shaped frame 2 32, and two guide wheels 2 33 respectively installed on the V-shaped frame 2. The V-shaped frame 2 is connected to the bracket 9 through the connecting rod 31. The two guide wheels 2 33 are in contact with the two outer surfaces of the support guide beam 4 respectively. When the bracket 9 moves up and down, the guide wheels 2 33 roll on the support guide beam 4, which plays a guiding role and can ensure the stability of the movement of the bracket 9.

[0031] The working principle of this invention is as follows: The material to be sprayed is placed on the horizontal chain 81 of the bracket 9. This invention can move the material vertically (upward and downward) and horizontally (leftward and rightward). The material is placed on a specific platform on the production line and transported to this invention via a conveyor line. Based on the received signal, this invention transports the material upward to a set height. Then, based on a set direction, this invention sends the material to another conveyor line on the production line to the left or right. The conveyor line then transports the material to the next process for continued operation. At this time, it can be set whether to transport other materials when the bracket descends, according to the production layout requirements. After this invention descends and resets, the above actions are repeated.
