Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics, in particular to a vertical logistics transmission mechanism for cold chain transportation. Background Art

[0002] Cold chain logistics mainly transports products that need to be kept fresh to ensure product quality. Cold chain logistics often uses cold chain logistics vehicles for transportation. Since the door of the cold chain logistics vehicle is at a certain height from the ground, lifting equipment is required for auxiliary transportation.

[0003] In the related technology, after searching, it was found that there is a scheme of a mobile unloading lifting frame based on cold chain logistics warehousing (Announcement No. CN212267574U), in which the upper and lower ends of the driven rod and the linkage rod are rotatably connected to the base and the unloading plate, ensuring that the driven rod and the linkage rod can move according to the stretching of the hydraulic column. The unloading plate pushes the connecting rod through the hydraulic column, thereby driving the rotation and up and down movement between the driven rod and the linkage rod, making the lifting and lowering of the unloading plate easier to control.

[0004] However, the unloading plate of the above scheme is flat, and the foam box is an insulated box commonly used in cold chain logistics. Dragging the insulated box from the unloading plate to the vehicle, or from the vehicle to the unloading plate, is likely to wear the insulated box and cause damage to the bottom of the insulated box. In addition, the scissor-type lifting structure has a limited lifting height. Utility Model Content

[0005] The purpose of the utility model is to provide a cold chain transport vertical logistics transmission mechanism to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical logistics transmission mechanism for cold chain transportation, including a mobile vehicle, which is electrically driven, making transportation more convenient and labor-saving;

[0007] The mobile vehicle is provided with a bracket, a lifting rod is slidably connected inside the bracket, a lead screw is transmission-connected in the middle of the lifting rod, a motor is installed on the surface of the mobile vehicle, and the motor is fixedly connected to the lead screw;

[0008] A placement plate is fixedly connected to the side of the lifting rod, an electric cylinder is installed on the lower surface of the placement plate, a support is installed on the upper end of the electric cylinder, a plurality of rollers are installed on the surface of the support, and the rollers penetrate the placement plate;

[0009] The lifting and lowering of the placement plate is controlled by a motor and a lead screw. The lifting range of the placement plate can be changed according to the length of the lead screw, and the goods can be lifted to a higher place.

[0010] Furthermore, a plurality of pulleys are installed on the surface of the lifting rod, and the pulleys are rollingly connected to the bracket. The pulleys can reduce the lifting resistance of the lifting rod, and no abnormal noise or jamming problems will occur during the lifting process.

[0011] Furthermore, a handrail is fixedly connected to the side of the bracket, and the handrail is used to facilitate the control of the moving position of the mobile vehicle and control the mobile vehicle to stop at a designated position.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The support and roller are controlled by an electric cylinder to rise and fall. When the roller is located below the placement plate, the incubator will not slide when placed on the placement plate, thus preventing the incubator from falling. When the roller protrudes from the placement plate, the rotation of the roller will not wear the incubator when the incubator is pushed, thus preventing damage to the incubator and achieving a better preservation effect on the product.

[0014] (2) The motor drives the lead screw to rotate, and the lifting rod connected to the lead screw can move up and down. The lifting range of the lifting rod corresponds to the lead screw, which has a flexible and free lifting range selection. It is not only convenient to transfer the insulated box between the placement plate and the cold chain logistics vehicle, but also convenient to move the insulated box to the multi-layer shelf, which has richer application scenarios.

[0020] 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.

[0021] Example:

[0022] See also Figure 1-4 , the utility model provides a technical solution: a cold chain transport vertical logistics transmission mechanism, including a mobile vehicle 1, the mobile vehicle 1 adopts a hub motor 6, the hub motor 6 has the advantages of light weight and miniaturization, occupies a small space, and makes the entire transmission mechanism structure more compact;

[0023] A bracket 4 is installed on the mobile vehicle 1. The bracket 4 is arranged in an N shape. A lifting rod 10 is slidably connected inside the bracket 4. Both ends of the lifting rod 10 are slidably connected to the bracket 4 to ensure that the lifting rod 10 moves up and down more stably. A lead screw 11 is connected to the middle of the lifting rod 10. A motor 6 is installed on the surface of the mobile vehicle 1. The motor 6 is fixedly connected to the lead screw 11. The motor 6 is used to control the rotation of the lead screw 11. The lead screw 11 is connected to the lifting rod 10. Both ends of the lifting rod 10 are limited by the bracket 4 and will not rotate, ensuring that the lifting rod 10 is smoothly controlled by the lead screw 11 to rise and fall;

[0024] A placement plate 3 is fixedly connected to the side of the lifting rod 10, an electric cylinder 9 is installed on the lower surface of the placement plate 3, a support 14 is installed on the upper end of the electric cylinder 9, and a plurality of rollers 13 are installed on the surface of the support 14. The rollers 13 penetrate the placement plate 3, and the electric cylinder 9 controls the lifting and lowering of the rollers 13. When the insulated box is transported, the rollers 13 do not contact the insulated box, so as to prevent the insulated box from sliding off the placement plate 3 due to inertia.

[0025] In this embodiment, if Figure 1 As shown, a battery pack 7 is placed on the mobile vehicle 1, and the battery pack 7 is electrically connected to the mobile vehicle 1 and the electric cylinder 9. The battery pack 7 can be charged. Placing the battery pack 7 on the mobile vehicle 1 can lower the center of gravity and prevent the transmission mechanism from shaking and tipping over when the incubator is transported to a high place.

[0026] In this embodiment, if Figure 3 As shown, a plurality of pulleys 15 are installed on the surface of the lifting rod 10, and the pulleys 15 are rollingly connected to the bracket 4. The pulleys 15 replace the sliding friction between the bracket 4 and the lifting rod 10 with rolling friction, thereby reducing the resistance of the lifting rod 10 to the up and down movement and reducing the wear between the lifting rod 10 and the bracket 4.

[0027] In this embodiment, if Figure 3 As shown, a U-shaped seat 8 is fixedly connected to the lower surface of the placement plate 3, and the electric cylinder 9 is installed inside the U-shaped seat 8. The U-shaped seat 8 supports the electric cylinder 9 to ensure that the electric cylinder 9 can smoothly control the support 14 to move up and down.

[0028] In this embodiment, if Figure 4As shown, a plurality of openings 12 are provided on the surface of the placement plate 3 , and the positions of the openings 12 correspond to the rollers 13 . The openings 12 provide space for the lifting and lowering of the rollers 13 , and are also helpful in reducing the weight of the placement plate 3 .

[0029] In this embodiment, if Figure 2 As shown, a handrail 5 is fixedly connected to the side of the bracket 4, and the handrail 5 is used to facilitate the control of the moving vehicle 1 to move forward.

[0030] In this embodiment, if Figure 1 As shown, a limit rod 2 is fixedly connected to the upper surface of the mobile vehicle 1 , and the limit rod 2 is used to support the placement plate 3 to prevent the placement plate 3 from touching the battery pack 7 .

[0031] Specifically, during use, before the incubator is transported to the placement plate 3, the electric cylinder 9 first controls the support 14 to move upward, and the support 14 drives the roller 13 to move upward. The roller 13 protrudes on the placement plate 3. When the incubator is dragged toward the placement plate 3, the rotation of the roller 13 can prevent the incubator from being rubbed by the placement plate 3, and dragging the incubator to move is also more labor-saving. The electric cylinder 9 controls the roller 13 to move downward, so that the roller 13 moves up and is placed on the placement plate 3. The incubator can be transported to a designated location using the mobile vehicle 1. The motor 6 controls the screw 11 to rotate, and the screw 11 drives the lifting rod 10 to move up and down along the bracket 4. The lifting rod 10 drives the placement plate 3 to move upward, and the incubator is transported to a high place. When removing the incubator from the placement plate 3, the electric cylinder 9 controls the roller 13 to move upward, which is convenient for dragging the incubator off the incubator.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
