[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Please refer to Figures 1-4, the present utility model provides a crystal carrier transport trolley with a matching function, including a fixing frame 1: a top plate 5 is fixed at the top end of the fixing frame 1; a placing assembly is arranged at the top end of the top plate 5; fixing rods 2 are fixed on the inner sides of the lower ends of the fixing frame 1; moving wheels 8 are fixed at the four corner positions of the lower end of the fixing frame 1; positioning assemblies are arranged on the outer sides of both ends of the fixing rod 2; the positioning assembly includes a fixing seat 11; the fixing seat 11 is fixed at the outer side position of the fixing rod 2; a second fixing shaft 13 is fixed on the side of the fixing seat 11 away from the fixing rod 2; a second bearing 12 is fixed at the middle position of the second fixing shaft 13; a first fixing shaft 9 is fixed on the inner side of one end of the fixing rod 2 close to the fixing seat 11; a first bearing 10 is fixed on the outer side of the first fixing shaft 9; a handle 7 is fixed at one end of the fixing frame 1. During operation, when the device is about to stop at the stop position and precise positioning is required, the operator can accurately stop the fixing frame 1 at the stop position through the positioning assembly. At the same time, when placing the ingot on the placing assembly, the ingot can be adjusted and positioned, making the placement of the ingot more orderly and facilitating transportation. This step can effectively, through the structural design of the positioning assembly, accurately position the fixing frame 1, thereby effectively avoiding the situation where the device cannot stop at the predetermined stop position due to manual pushing, resulting in inconvenient unloading of the ingot transported by the device, improving the stability and accuracy of the device, and enhancing the practicality of the device;

[0026] Further, as Figure 1 and Figure 2 shown, a positioning block 4 is arranged at a position corresponding to the first bearing 10 below the fixing rod 2; the positioning block 4 is in rolling connection with the first bearing 10; a guiding block 3 is arranged on the outer side of the fixing rod 2 adjacent to the positioning block 4; the guiding block 3 is in rolling connection with the second bearing 12; the positioning block 4 and the guiding block 3 are respectively fixed to the ground. During operation, first, the second bearings 12 on both sides of the fixing frame 1 are aligned with the guiding blocks 3, so that the second bearings 12 move to the inner sides of the guiding blocks 3, thereby positioning the fixing frame 1 in the left-right direction through the cooperation of the guiding blocks 3 and the second bearings 12. At the same time, the first bearing 10 moves to the top of the positioning block 4, so that the fixing frame 1 is positioned up and down through the cooperation of the first bearing 10 and the positioning block 4. Subsequently, by locking the moving wheels 8, the device is completely stopped and will not move. This step can effectively avoid the situation where the device cannot stop at the predetermined stop position due to manual pushing, resulting in inconvenient unloading of the ingot transported by the device, improving the stability and accuracy of the device, and enhancing the practicality of the device.

[0027] Further, as Figure 3As shown, the placement component includes a plurality of placement racks 6; the plurality of placement racks 6 are respectively fixed at the top end position of the top plate 5; a plurality of placement slots are evenly opened at the top end of the placement rack 6; a fixed cylinder 16 is fixed inside the placement rack 6; clamping components are arranged at both ends of the fixed cylinder 16. During operation, when placing the ingot, first place the ingot in the placement slots at the top end of the placement rack 6, and then move the two ends of the ingot towards the middle position through the clamping components, so that the center of gravity of the ingot is at the middle position. This step can effectively, through the cooperative structural design of the fixed cylinder 16 and the clamping components, enable the ingot placed at the top end of the placement rack 6 to be clamped while adjusting the position of the ingot, thereby improving the stability and neatness of the ingot placement, and thus avoiding the situation where the ingot falls off due to unstable placement of the ingot during transportation, and improving the stability of transportation.

[0028] As Figure 3 shown, the clamping component includes an internal threaded rod 17; the internal threaded rod 17 is arranged at the inner middle position of the fixed cylinder 16; the internal threaded rod 17 is rotationally connected to the fixed cylinder 16; transmission screw rods 18 are threadedly connected to both inner sides of the two ends of the fixed cylinder 16; a moving column 19 is fixed at one end of the transmission screw rod 18 away from the internal threaded rod 17; the moving column 19 is slidably connected to the fixed cylinder 16; one end of the moving column 19 away from the transmission screw rod 18 extends to the outside of the top plate 5; a moving plate 20 is fixed at the top end of one end of the moving column 19 away from the transmission screw rod 18; a driving component is arranged at the middle position of the internal threaded rod 17. During operation, when it is necessary to clamp the ingot, first drive the internal threaded rod 17 to rotate through the driving component. When the internal threaded rod 17 rotates, it drives the moving column 19 to move along the axial direction of the transmission screw rod 18 through the transmission screw rod 18 threadedly connected thereto, so that the moving column 19 drives the moving plate 20 to move towards the direction close to the ingot, thereby being able to clamp the ingot. This step can, through the cooperative structural design of the driving component, internal threaded rod 17, transmission screw rod 18, moving column 19 and moving plate 20, enable the ingot to be clamped and adjusted, thereby improving the stability of the ingot transportation.

[0029] As Figure 3 and Figure 4As shown, the driving component includes a motor 21; the motor 21 is fixed at the top end of one end of the top plate 5; a transmission rod 22 is fixed to the output end of the motor 21; the transmission rod 22 is rotatably connected to the top plate 5; a plurality of worm gears 23 are evenly fixed on the outer side of the transmission rod 22 corresponding to the built-in threaded rod 17; a worm wheel 24 is fixed at the position of the built-in threaded rod 17 corresponding to the worm gear 23; the worm wheel 24 is meshed with the worm gear 23. During operation, when it is necessary to rotate the built-in threaded rod 17, first start the motor 21, so that the motor 21 drives the worm gear 23 to rotate through the transmission rod 22. When the worm gear 23 rotates, it drives the built-in threaded rod 17 to rotate through the worm wheel 24 meshed with it. This step can effectively drive the built-in threaded rod 17 to rotate through the matching structure design of the worm gear 23 and the worm wheel 24, providing power for the rotation of the built-in threaded rod 17.

[0030] As Figure 3 shown, rubber protection pads 14 are fixedly arranged on the inner sides of the fixing cylinders 16 located in the placement grooves. This step can effectively buffer the ingot placed in the placement groove through the rubber protection pads 14, avoiding bump damage to the ingot during placement.

[0031] As Figure 3 shown, a contact plate 15 is fixed to the side of the moving plate 20 close to the placement rack 6. This step can avoid hard contact with the ingot when clamping the end of the ingot through the contact plate 15, preventing damage to the ingot.

[0032] Working principle: When the device is about to stop at the stop position and precise positioning is required, the operator can accurately stop the fixing frame 1 at the stop position through the positioning component. At the same time, when placing the ingot on the placing component, the ingot can be adjusted and positioned, making the placement of the ingot neater and facilitating transportation. First, the second bearings 12 on both sides of the fixing frame 1 are aligned with the guide blocks 3, so that the second bearings 12 move to the inside of the guide blocks 3, thereby positioning the fixing frame 1 in the left-right direction through the cooperation of the guide blocks 3 and the second bearings 12. At the same time, the first bearings 10 move to the top of the positioning blocks 4, so that the fixing frame 1 is positioned up and down through the cooperation of the first bearings 10 and the positioning blocks 4. Subsequently, by locking the moving wheels 8, the device completely stops and does not move. When placing the ingot, first place the ingot in the placing groove at the top of the placing frame 6, and then move the two ends of the ingot towards the middle position through the clamping component, so that the center of gravity of the ingot is at the middle position. When the ingot needs to be clamped, first drive the built-in threaded rod 17 to rotate through the driving component. When the built-in threaded rod 17 rotates, it drives the moving column 19 to move along the axial direction of the transmission screw rod 18 through the transmission screw rod 18 threadedly connected thereto, so that the moving column 19 drives the moving plate 20 to move towards the ingot, thereby being able to clamp the ingot. When the built-in threaded rod 17 needs to be rotated, first start the motor 21, so that the motor 21 drives the worm 23 to rotate through the transmission rod 22. When the worm 23 rotates, it drives the built-in threaded rod 17 to rotate through the worm gear 24 meshed therewith.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
