[0007] The first mounting bracket is fixedly mounted on the main frame;

[0008] The second mounting bracket is slidably mounted on the first mounting bracket;

[0009] The second mounting bracket has a first guide groove on its outer side for the first mounting bracket to roll into contact with it, and a second guide groove on its inner side for the worktable to roll into contact with it.

[0010] The support includes uprights on both sides and a crossbeam at the top. The uprights and bottom rail are made of I-beams, and the top rail is made of C-shaped steel. The main frame is in rolling engagement with the uprights on both sides, and the crossbeam is in rolling engagement with the top rail.

[0011] The bracket has a base at its bottom, and the left and right ends of the base are provided with guide plates that are adapted to the bottom rail. The guide plates are provided with T-shaped grooves that match the I-beams.

[0012] Limit switches are installed at both ends of the column and on the guide plate, and limit anti-collision blocks are provided at both ends of the bottom rail.

[0018] Figure 2 This is a schematic diagram of the bottom structure of a painting lifting platform.

[0019] Figure 3 This is a schematic diagram of the guide clamp. Detailed Implementation

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0021] As shown in the figure, a painting lifting platform includes a support frame and a top rail 2 and a bottom rail 3 for the support frame to be rolled and mounted. The bottom of the support frame is provided with a roller 14 and a first driving member 15 for driving the roller 14. The support frame is provided with a platform mechanism 4 and a second driving member 5 for driving the platform mechanism 4 to move up and down on the support frame. The platform mechanism 4 includes a telescopic frame assembly and a worktable 41 that is slidably mounted on the telescopic frame assembly. The telescopic frame assembly is provided with a third driving member 42 for driving the worktable 41 to move laterally.

[0022] The telescopic frame assembly includes:

[0023] The main frame 43 is slidably mounted on the bracket.

[0024] The first mounting bracket 44 is fixedly mounted on the main body frame 43;

[0025] The second mounting bracket 45 is slidably mounted on the first mounting bracket 44;

[0026] The second mounting bracket 45 has a first guide groove 46 on its outer side for the first mounting bracket 44 to roll into, and a second guide groove 47 on its inner side for the worktable 41 to roll into. This technical solution provides top and bottom rails at the upper and lower positions of the bracket to ensure stable left and right movement of the bracket and the platform mechanism on the bracket. In addition, the main frame of the platform mechanism slides stably up and down on the bracket, and the telescopic frame assembly drives the worktable to move horizontally, allowing the workers to smoothly approach and move away from the coating work surface. It has the advantages of stable operation and good safety.

[0027] The first driving component 15 uses a servo motor and a reducer.

[0028] The second driving component 5 and the third driving component 42 adopt servo motors and ball screw pairs. When the third driving component drives the worktable to move, the rollers on both sides of the worktable roll in the second guide groove, and the rollers on both sides of the second mounting bracket roll in the first guide groove, which has the advantage of smooth movement of the worktable.

[0029] The support includes uprights 11 on both sides and a crossbeam 12 on the top. The uprights 11 and the bottom rail 3 are made of I-beams, and the top rail 2 is made of C-shaped steel. The main frame 43 is in rolling engagement with the uprights 11 on both sides, and the crossbeam 12 is in rolling engagement with the top rail 2. The I-beams and C-shaped steel are inexpensive to purchase and easy to install.

[0030] The support has a base 13 at the bottom, and guide plates 16 adapted to the bottom rail 3 are provided at the left and right ends of the base 13. The guide plates 16 are provided with T-shaped grooves 17 that match the I-beams. The guide plates are used for limiting and ensuring the stability of the base during operation.

[0031] Limit switches 18 are installed at both ends of the column 11 and on the guide plate 16. Limiting anti-collision blocks 31 are provided at both ends of the bottom rail 3. The limit switches are connected to the servo motor. When the limit switches collide with the limiting anti-collision blocks, the limit switch contacts are activated to connect or disconnect the control circuit, thereby achieving a certain control purpose.

[0032] The workbench 41 is equipped with guardrails 48 around its perimeter to improve safety during work.
