DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a positioning device for assembling a refrigerator box body, comprising a base plate 1, a push plate 3 for pushing the bottom plate of the refrigerator box body to move is slidably connected to the top surface of the base plate 1, a support leg 8 is fixedly installed on the bottom surface of the base plate 1, and the support leg 8 can support the base plate 1, and a limit frame 9 is fixedly installed on the top surface of the base plate 1. The limit frame 9 is a U-shaped structure, and the limit frame 9 can limit the front plate. The top surface of the base plate 1 is provided with an assembly positioning mechanism 4 for positioning the box body assembly, and one side of the push plate 3 is provided with an anti-displacement mechanism 2 for limiting the movement of the bottom plate;

[0024] The assembly positioning mechanism 4 includes two rotating seats 24, and the two rotating seats 24 are fixedly installed on the top surface of the base plate 1. The interior of the rotating seat 24 is rotatably connected with a second cylinder 26. Both sides of the second cylinder 26 are fixedly installed with a support shaft 25, and the support shaft 25 is rotatably connected to the rotating seat 24. One end of the telescopic shaft of the second cylinder 26 is rotatably connected to one side of the push plate 3. One side of the push plate 3 is fixedly installed with two connecting frames 13, and the outer circumferential wall surface of the telescopic shaft of the second cylinder 26 is fixedly installed with two connecting shafts 27, and the connecting shaft 27 is rotatably connected to the connecting frame 13. The top surface of the base plate 1 is slidably connected with two walking frames 5, and the inner top surface of the walking frame 5 is fixedly installed with an electric hoist 6 for hoisting the side panel of the box body, and the electric hoist 6 is equipped with a wire rope and a hook. This is the prior art and will not be repeated here. The top surface of the base plate 1 is fixedly installed with a plurality of first cylinders 7 for driving the walking frame 5 to move;

[0025] Through the provided base plate 1, the staff places the bottom plate of the refrigerated truck body on the top surface of the base plate 1, and the staff places the front plate of the refrigerated truck body inside the limiting frame 9, which can position the front plate, and the staff starts the second cylinder 26, and the telescopic shaft of the second cylinder 26 moves outward to drive the push plate 3 to move forward on the base plate 1. At this time, the telescopic shaft of the second cylinder 26 drives the connecting shaft 27 to rotate on the connecting frame 13, and the second cylinder 26 also drives the supporting shaft 25 to rotate on the rotating seat 24. The forward movement of the push plate 3 will push the bottom plate forward until one side of the bottom plate abuts against one side of the front plate, and The staff then uses the electric hoist 6 on the traveling frame 5 to lift the side panels of the refrigerated truck body. The staff starts the first cylinder 7. The telescopic shaft of the first cylinder 7 moves forward to drive the traveling frame 5, the electric hoist 6 and the side panels to move forward until the side panels abut against the sides of the bottom plate and the front plate, thereby positioning and assembling the bottom plate, the front plate and the side panels of the refrigerated truck body, thereby achieving the positioning and assembly effect of the refrigerated truck body. Compared with the assembly of the refrigerated truck body in the prior art, the staff does not need to assemble the box body panels by hand, and it is easier to position the bottom plate, the front plate and the side panels of the refrigerated truck body, which is convenient for the staff to assemble the refrigerated truck body.

[0026] The anti-displacement mechanism 2 includes a support plate 16, which is fixedly mounted on one side of the push plate 3. A liftable support frame 12 is mounted on the bottom surface of the support plate 16. The support frame 12 is a U-shaped structure. A threaded rod 17 is threadedly connected to the top surface of the support plate 16. The lower end of the threaded rod 17 is rotatably connected to the top surface of the support frame 12 through a bearing.

[0027] By using the push plate 3, when the bottom plate of the refrigerated truck body is moved by using the push plate 3, the staff rotates the threaded rod 17 to drive the bearing to rotate while the support frame 12 does not rotate. The rotation of the threaded rod 17 also causes the threaded rod 17 to drive the support frame 12 to move downward until the inner sides of the support frame 12 are respectively in contact with the two sides of the bottom plate of the refrigerated truck body. The support frame 12 can limit the movement of the bottom plate to prevent the bottom plate of the refrigerated truck body from shifting horizontally and avoid the bottom plate of the refrigerated truck body from being misaligned with the front plate.

[0028] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the positioning device for assembling the box body of a refrigerated truck is different from the embodiment 1 in that two supporting grooves 18 are provided on the top surface of the base plate 1, and two mounting frames 20 are fixedly installed on the bottom surface of the push plate 3. The mounting frames 20 are slidably connected to the supporting grooves 18, and the internal rotation of the mounting frames 20 is connected to rollers 21. Both ends of the rollers 21 are fixedly installed with rotating shafts 22, and the rotating shafts 22 are rotatably connected to the mounting frames 20. Limiting grooves 19 are provided on both sides of the interior of the supporting grooves 18. Limiting blocks 23 for limiting the movement of the mounting frames 20 are fixedly installed on both sides of the mounting frames 20. The limiting blocks 23 are slidably connected to the limiting grooves 19. Through the provided mounting frames 20, the internal movement of the mounting frames 20 in the supporting grooves 18 on the base plate 1 drives the limiting blocks 23 to move in the limiting grooves 19 on the inner side of the supporting grooves 18. The limiting blocks 23 can limit the movement of the mounting frames 20 to prevent the mounting frames 20 from falling off from the supporting grooves 18;

[0029] By means of the push plate 3, the push plate 3 moves forward to drive the mounting frame 20 to move inside the support groove 18 on the substrate 1. The mounting frame 20 moves inside the support groove 18 to drive the roller 21 to roll inside the support groove 18. At the same time, the roller 21 drives the rotating shaft 22 to rotate on the mounting frame 20. The mounting frame 20, the roller 21 and the rotating shaft 22 cooperate to improve the smoothness of the movement of the push plate 3 on the substrate 1, thereby ensuring the stable movement of the push plate 3 on the substrate 1.

[0030] The top surface of the base plate 1 is provided with a plurality of mounting grooves 10, and a support roller 11 is rotatably connected inside the mounting groove 10. Both ends of the support roller 11 are fixedly installed with a connecting column 28, and the connecting column 28 is rotatably connected to one side of the inner side of the mounting groove 10 through a bearing;

[0031] By setting the base plate 1, the bottom plate of the refrigerated vehicle body moves on the base plate 1 so as to drive the support roller 11 to rotate inside the mounting groove 10. The rotation of the support roller 11 will also drive the connecting column 28 and the inner ring of the bearing to rotate. The rotation of the support roller 11 can reduce the friction between the bottom plate of the refrigerated vehicle body and the base plate 1, thereby improving the smoothness of the movement of the bottom plate of the refrigerated vehicle body on the base plate 1.

[0032] The top surface of the base plate 1 is provided with a plurality of limiting grooves 14 for the sliding of the walking frame 5. Both sides of the inner part of the limiting grooves 14 are inclined toward the middle position of the limiting grooves 14. Two limiting blocks 15 are fixedly installed on the bottom surface of the walking frame 5. The limiting blocks 15 are slidably connected with the limiting grooves 14. Through the setting of the walking frame 5, the walking frame 5 moves on the base plate 1 to drive the limiting blocks 15 to move inside the limiting grooves 14. The limiting grooves 14 and the limiting blocks 15 can cooperate to limit the movement of the walking frame 5, thereby achieving a limiting effect on the walking frame 5.

[0033] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
