[0002] Truss robots, also known as rectangular coordinate robots, are multi-purpose manipulators that can realize automatic control, reprogrammable, multi-degree-of-freedom, and the degrees of freedom of motion are built into a spatial rectangular relationship. The rectangular coordinate machine can be used in common industrial production fields such as dispensing, plastic dripping, spraying, palletizing, sorting, packaging, welding, metal processing, handling, loading and unloading, assembly, printing, etc.

[0003] After checking the disclosure (announcement) number: CN214686555U, a truss robot lifting mechanism is disclosed. This technology discloses technical solutions such as "starting the second drive motor, the second drive motor drives the first bevel gear to rotate, the first bevel gear drives the worm to rotate through the second bevel gear, the sprocket and the chain, and the worm drives the winding wheel to rotate through the worm wheel", which has technical effects such as "the winding wheel drives the clamping assembly to be lifted and lowered through the pull rope, and the operation is more convenient";

[0004] However, when the truss robot is working, if it is moving objects from a low place on one side to a high place on the other side, or from a high place to a low place, at least two linear guide rails and drive elements of the Y-axis and Z-axis are required, which increases production costs, and the steps of the Y-axis and Z-axis need to be executed separately, reducing production efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a truss robot heavy-load lifting mechanism, which has the characteristics of only requiring one reduction motor to control the lifting and lowering of the transported goods during the left and right movement, and the movement is stable.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a truss robot heavy-load lifting mechanism, including a truss robot, the truss robot is provided with a conveying mechanism and is used to convey goods, the conveying mechanism includes:

[0007] A guide assembly, including a cross frame fixed to the upper end of the truss robot;

[0008] The actuator assembly comprises a slide frame slidably mounted on the horizontal frame through a guide rail frame, and a first guide wheel and a second guide wheel are respectively mounted on both sides of the interior of the slide frame;

[0009] The driving assembly includes a mounting frame fixed to the outer wall of the right end of the horizontal frame, a winding drum installed at the lower end of the outer wall of the mounting frame, a reduction motor installed on the mounting frame and used to drive the winding drum to rotate, a main rope fixed to the outer wall of the right end of the slide, a first rope and a second rope fixed to the inner wall of the left end of the horizontal frame, and a bracket installed between the lower end of the first rope and the lower end of the second rope and used to carry goods.

[0010] Preferably, the conveying mechanism also includes a guide rail frame fixed to the front and rear ends of the top of the cross frame, and rollers are installed on both sides of the front and rear ends of the slide frame, and the rollers are located inside the guide rail frame.

[0011] Preferably, the conveying mechanism also includes a circular hole opened inside the right end of the horizontal frame, and one end of the main rope passes through the circular hole and is wound around the winding disk, and the first rope and the second rope are respectively wound around the first guide wheel and the second guide wheel for guidance.

[0012] Preferably, the conveying mechanism also includes a guide rope wheel installed on the upper end of the outer wall of the mounting frame, and the main rope is wound on the guide rope wheel for guidance.

[0013] Preferably, guide frames are fixed to both the front and rear ends of the cross frame, a guide rod is fixed to the top of the bracket, and the guide rod runs through the interior of the guide frame.

[0014] Preferably, the bracket is connected to the first rope and the second rope through bolts and nuts.

[0015] Beneficial Effects

[0016] The utility model provides a heavy-load lifting mechanism for a truss robot. Compared with the prior art, it has the following beneficial effects:

[0017] (1) The output end of the reduction motor is rotated forward to drive the reel to reel in the main rope, and the main rope pulls the slide to move to the right. At the same time, the slide cooperates with the first rope and the second rope through the first guide wheel and the second guide wheel to drive the bracket to move to the right and rise upward. Similarly, the output end of the reduction motor is rotated in the reverse direction to control the bracket to move to the left and descend, so that only one reduction motor is needed to control the lifting and lowering of the transported goods during the left and right movement.

[0018] (2) Since the bracket is prone to shaking after being directly lifted by the first rope and the second rope, a guide rod is added to the bracket so that the guide rod moves along the inside of the guide frame during the movement of the bracket, thereby stabilizing the bracket to prevent it from shaking and avoid safety hazards caused by cargo falling.

[0030] In this embodiment, the output end of the reduction motor 233 is used to drive the winding disk 232 to reel in the main rope 234 by positive rotation. The main rope 234 pulls the slide 221 to move to the right. At the same time, the slide 221 cooperates with the first rope 235 and the second rope 236 through the first guide wheel 222 and the second guide wheel 223 to drive the bracket 3 to move, so that the bracket 3 moves to the right and rises upward. Similarly, by rotating the output end of the reduction motor 233 in the opposite direction, the bracket 3 can be controlled to move to the left and descend.

[0031] Specifically, the conveying mechanism 2 further includes a guide rail frame 212 fixed to the front and rear ends of the top of the cross frame 211 , and rollers 224 are installed on both sides of the front and rear ends of the slide 221 , and the rollers 224 are located inside the guide rail frame 212 .

[0037] Specifically, the bracket 3 is connected to the first rope 235 and the second rope 236 through bolts and nuts.

[0038] In this embodiment, the bracket 3 can be disassembled and replaced according to the size of the transported goods.

[0039] The working principle and use process of the utility model are as follows: first, according to the size of the goods to be transported, the bracket 3 is connected to the first rope 235 and the second rope 236 through bolts and nuts, and the goods are moved to the bracket 3; then, the output end of the reduction motor 233 is used to drive the winding disk 232 to reel in the main rope 234 by positive rotation, and the main rope 234 pulls the slide 221 to move to the right. At the same time, the slide 221 cooperates with the first rope 235 and the second rope 236 through the first guide wheel 222 and the second guide wheel 223 to drive the bracket 3 to move, so that the bracket 3 moves to the right and rises upward; and during the movement of the bracket 3, the guide rod 5 moves along the inside of the guide frame 4, so that the bracket 3 can be stabilized to prevent it from shaking.
