Description

Technical Field

[0001] The utility model relates to the technical field of transplanting trolleys, in particular to a power-free driven transplanting trolley. Background Art

[0002] Traditional transplanting equipment is often used to transfer semi-finished products between two different devices in the manufacturing process of specific product lines. For transplanting between workshop-level environments, specific transplanting trolleys are often used for transportation.

[0003] A Chinese patent with the publication number CN215100188U discloses a full-automatic transplanting trolley, including a conveying track and a trolley body running on the conveying track. The trolley body includes a frame. A pulley is provided at the connection between the lower end of the frame and the conveying track. It is characterized in that a conveying mechanism is slidably connected inside the frame, and a lifting mechanism for moving the conveying mechanism up and down is provided above the frame. Compared with the prior art, the beneficial effects of the present utility model are as follows: The transplanting trolley of the present utility model can walk back and forth on the conveying track. The conveying mechanism on the frame can transfer the materials on the main line to the conveying mechanism, and transport the materials to the transplanting line on the conveying track. The lifting mechanism can drive the conveying mechanism to move up and down to facilitate production lines at different heights.

[0004] During the movement of the existing transplanting trolleys, they usually can only move in a single direction and cannot conveniently change the driving direction of the trolleys, resulting in poor convenience for the trolleys to change directions. Therefore, a power-free driven transplanting trolley is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems existing in the prior art, the present utility model proposes a power-free driven transplanting trolley.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A power-free driven transplanting trolley of the present utility model includes a support frame. A bottom cross beam and a bottom longitudinal beam are installed on the bottom side of the support frame. A connecting beam is installed on the support frame. A first support rod is installed between the connecting beam and the bottom cross beam. A first fixing frame is installed on the first support rod. A first counterweight frame is installed on the first fixing frame. A second support rod is installed between the connecting beam and the bottom cross beam. A second fixing frame is installed on the second support rod. A second counterweight frame is installed on the second fixing frame. The first fixing frame and the second fixing frame are symmetrically arranged. Two groups of rotating shafts are rotatably installed between the bottom longitudinal beams. Pulleys are installed on the rotating shafts. A first gear is fixedly sleeved on one of the rotating shafts. An assembly rod is installed between the bottom cross beams. An assembly block is installed at the center of the assembly rod. A second gear is rotatably installed on the assembly block. A support column is installed on the assembly block. The support column, the second gear, and the first gear form a synchronous belt linear module. A group of top cross beams and two groups of top longitudinal beams are installed on the support frame. A first fixing rod and a second fixing rod are symmetrically installed on the support frame. By placing a counterweight block on the first counterweight frame, a force called "gravity component" is generated, which causes the pulley to start rolling, and the trolley slides obliquely with the material box, realizing the handling of the material box. By placing the counterweight block on the second counterweight frame, under the action of the "gravity component", the transplanting trolley moves back to its original position along the slope, realizing the driving of the trolley's traveling direction through the counterweight exchange method, which is beneficial to improving the convenience of the trolley's direction change.

[0007] Preferably, a plurality of first fixing blocks are installed on the first fixing rod. Sliding channels are installed on the first fixing blocks. A plurality of rollers are rotatably installed on the inner walls of the sliding channels. The rollers and the sliding channels form a flow strip. The other end of the sliding channel is installed with a second fixing block. The second fixing block is fixedly sleeved on the second fixing rod. The second fixing rod is located below the top cross beam. By placing the material box on the rollers of the sliding channel, the trolley slides obliquely downward with the material box. Blocked by another working platform, the trolley stops moving, while the material box will continue to move forward under the action of inertia. The material box moves forward on the rollers and slides out of the sliding channel and onto another working platform, realizing the convenient transfer of the material box to another working platform, which is beneficial to improving the convenience of the trolley's transplanting.

[0008] The advantages of the present utility model are as follows:

[0009] 1. The utility model generates a force called "gravity component" by placing the counterweight on the first counterweight frame, which makes the pulley start to roll, and the trolley carrying the material box slides obliquely, thereby realizing the transportation of the material box. The counterweight is placed on the second counterweight frame. Under the action of the "gravity component", the transplanting trolley moves back to its original position along the slope, realizing the driving direction of the trolley by counterweight exchange, which is beneficial to improving the convenience of the trolley changing direction.

[0010] 2. The utility model places the material box on the rollers of the slide, and the trolley carrying the material box slides obliquely downward. When it is blocked by another workbench, the trolley stops moving, while the material box continues to move forward under the action of inertia. The material box moves forward on the rollers, slides out of the slide and slides onto another workbench, thereby realizing the convenient transfer of the material box to another workbench, which is beneficial to improving the convenience of transplanting with the trolley.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0017] Please refer to Figures 1-3 As shown, a power-free driven transplanting trolley includes a support frame 1. A bottom cross beam 4 and a bottom longitudinal beam 5 are installed on the bottom side of the support frame 1. A connecting beam 6 is installed on the support frame 1. A first support rod 7 is installed between the connecting beam 6 and the bottom cross beam 4. A first fixing frame 8 is installed on the first support rod 7. A first counterweight frame 9 is installed on the first fixing frame 8. A second support rod 10 is installed between the connecting beam 6 and the bottom cross beam 4. A second fixing frame 11 is installed on the second support rod 10. A second counterweight frame 12 is installed on the second fixing frame 11. The first fixing frame 8 and the second fixing frame 11 are symmetrically arranged. Two groups of rotating shafts 24 are rotatably installed between the bottom longitudinal beams 5. A pulley 13 is installed on the rotating shaft 24. A first gear 14 is fixedly sleeved on one of the rotating shafts 24. An assembly rod 25 is installed between the bottom cross beams 4. An assembly block 15 is installed at the center of the assembly rod 25. A second gear 16 is rotatably installed on the assembly block 15. A support column 17 is installed on the assembly block 15. The support column 17, the second gear 16, and the first gear 14 form a synchronous belt linear module. A group of top cross beams 2 and two groups of top longitudinal beams 3 are installed on the support frame 1. A first fixing rod 18 and a second fixing rod 19 are symmetrically installed on the support frame 1. A plurality of first fixing blocks 20 are installed on the first fixing rod 18. A slideway 21 is installed on the first fixing block 20. A plurality of rollers 22 are rotatably installed on the inner wall of the slideway 21. The rollers 22 and the slideway 21 form a flow strip. The other end of the slideway 21 is installed with a second fixing block 23. The second fixing block 23 is fixedly sleeved on the second fixing rod 19. The second fixing rod 19 is located below the top cross beam 2. During operation, in the process of moving, the existing transplanting trolley usually can only move in a single direction and cannot conveniently change the driving direction of the trolley, resulting in poor convenience in changing the direction of the trolley. By installing a guide rail on the ground and placing the transplanting trolley on the guide rail, the first gear 14 and the second gear 16 on the transplanting trolley are assembled in the tooth grooves of the guide rail. When the pulley 13 on the transplanting trolley rotates, it drives the whole transplanting trolley to move. The first gear 14 and the second gear 16 on the transplanting trolley rotate in the tooth grooves of the guide rail, so that the transplanting trolley moves stably in a straight line.

[0018] When the transplant trolley is operating, it is usually placed between two working platforms. The distance between the two working platforms is 8 meters. The transplant trolley is placed on one side of one of the working platforms. The ground between the two working platforms is a ramp structure. By placing the semi-finished products in the material box and placing the material box on the rollers 22 of the slideway 21, when the pulley 13 is on an inclined surface, the counterweight is placed on the first counterweight rack 9. Since the gravity of the counterweight is not completely perpendicular to the pulley 13, a force called "gravity component" is generated, which causes the pulley 13 to start rolling. The trolley slides down obliquely with the material box until the trolley moves to the other working platform and is blocked by the other working platform, and the trolley stops moving. However, the material box will continue to move forward under the action of inertia. The material box moves forward on the rollers 22, slides out of the slideway 21 and slides onto the other working platform, realizing the convenient transfer of the material box to the other working platform and improving the convenience of trolley transplanting. After that, the ground between the two working platforms changes to a ramp, making the position of the transplant trolley at a relatively high height. The counterweight is placed on the second counterweight rack 12. Under the action of the "gravity component", the transplant trolley moves back to its original position along the ramp, realizing the driving of the trolley's walking direction through the counterweight exchange method, which is beneficial to improving the convenience of trolley direction change.

[0019] Working principle: In the process of moving, the existing transplanting trolley can usually only move in a single direction and cannot conveniently change the driving direction of the trolley, resulting in poor convenience for the trolley to change direction. By installing a guide rail on the ground and placing the transplanting trolley on the guide rail, the first gear 14 and the second gear 16 on the transplanting trolley are assembled in the tooth grooves of the guide rail. When the pulley 13 of the transplanting trolley rotates, it drives the whole transplanting trolley to move. The first gear 14 and the second gear 16 on the transplanting trolley rotate in the tooth grooves of the guide rail, enabling the transplanting trolley to move stably in a straight line. When the transplanting trolley is working, it is usually placed between two working platforms, and the distance between the two working platforms is 8 meters. The transplanting trolley is placed on one side of one of the working platforms, and the ground between the two working platforms is a slope structure. By placing the semi-finished product in the material box and placing the material box on the rollers 22 of the slideway 21, when the pulley 13 is located on an inclined surface, the counterweight is placed on the first counterweight frame 9. Since the gravity of the counterweight is not completely perpendicular to the pulley 13, a force called "gravity component" is generated, which causes the pulley 13 to start rolling, and the trolley slides down obliquely with the material box until the trolley moves to another working platform and is blocked by the other working platform, and the trolley stops moving. However, the material box will continue to move forward under the action of inertia. The material box moves forward on the rollers 22, slides out of the slideway 21 and slides onto another working platform, realizing the convenient transfer of the material box to another working platform and improving the convenience of trolley transplanting. After that, the ground between the two working platforms changes to a slope, making the position of the transplanting trolley at a relatively high height. The counterweight is placed on the second counterweight frame 12, and under the action of the "gravity component", the transplanting trolley moves back to its original position along the slope, realizing the driving of the trolley walking direction through the counterweight exchange method, which is beneficial to improving the convenience of the trolley to change direction.
