Description

Technical Field

[0001] This utility model belongs to the technical field of unloading devices for logistics transportation, and specifically relates to an unloading rack for logistics cargo transportation. Background Technology

[0002] During the logistics and transportation of goods, it is necessary to unload goods from transport vehicles quickly and orderly. The commonly used device for assisting in unloading goods is the unloading rack. With the help of the unloading rack, workers do not need to directly carry heavy goods, but only need to perform some auxiliary operations, reducing labor costs and making unloading convenient. The unloading rack is generally composed of a base plate, support columns and unloading ramps. When workers unload goods in the vehicle, they manually move the goods to the top of the inclined ramp, apply a downward force to the goods, and under the action of the weight of the goods, the goods slide down the ramp, achieving the purpose of unloading.

[0003] During the unloading process, the goods move on the inclined plate, and there is friction between the goods and the inclined plate. If the goods are heavy or the downward force applied to the goods is small, the goods may stop on the inclined plate and cannot move down smoothly. In addition, if the downward speed of the goods is fast, the goods may deviate and collide with the inclined plate, or the goods may not stop at the bottom of the inclined plate due to inertia. The existing unloading rack cannot apply a downward force to the goods to make them move smoothly, nor can it apply damping friction force to the goods that are moving too fast to buffer and decelerate them, which has its shortcomings.

[0004] Existing unloading racks have the problem that they do not apply downward force and damping friction force to the goods during unloading. To address this, this application proposes an unloading rack for logistics cargo transportation. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: an unloading rack for logistics cargo transportation, including an unloading support, comprising a base plate 11, a first telescopic column 12 and a second telescopic column 13 perpendicular to the base plate 11, an unloading plate 14, a first unloading roller 15 and a second unloading roller 6 installed inside the unloading plate 14, wherein a cargo loading plate 141 and a cargo unloading plate 142 are respectively fixed at both ends of the unloading plate 14, and the cargo loading plate 141 and the cargo unloading plate 142 are fixed to the unloading plate 14 by bolts. Figure 1In this context, "A" represents well-packaged and neatly arranged goods. When unloading goods A, manual labor moves goods A onto the loading plate 141 and pushes it. Goods A slides on the surfaces of the first unloading roller 15 and the second unloading roller 6 within the inclined unloading plate 14, eventually falling onto the unloading plate 142, thus achieving unloading. The drive assembly includes a drive motor 21 fixed to the unloading plate 14 by screws, and a drive roller 22 installed inside the unloading plate 14 and connected to the output shaft of the drive motor 21. When the drive motor 21 starts, it causes the drive roller 22 to rotate clockwise, i.e., along... Figure 1 The drive roller 22 rotates in the d1 direction, causing the cargo A sliding inside the unloading plate 14 to be deflected by the rotation of the drive roller 22. This accelerates the descent of cargo A and prevents it from stopping and coming to rest in the center of the unloading plate 14. The damping assembly includes a damping motor 31 fixed to the unloading plate 14 by screws and a damping roller 32 installed inside the unloading plate 14 and connected to the output shaft of the damping motor 31. The damping motor 31 operates, causing the damping roller 32 to rotate counterclockwise, i.e., along the d1 direction. Figure 1 The damping roller 32 rotates in the d2 direction. The outer surface of the damping roller 32 is provided with an anti-slip damping pad, which can apply damping force to the cargo A to achieve the purpose of decelerating the cargo A. The friction assembly includes a stabilizing plate 51 fixed to the unloading plate 14 by screws, a fixing strip 52 perpendicular to the stabilizing plate 51, a damping pad plate 53 bonded to the stabilizing plate 51 by adhesive, and a damping pad strip 54 bonded to the fixing strip 52 by adhesive. The damping pad plate 53 and the damping pad strip 54 are made of rubber material and have damping texture on the surface. The damping pad plate 53 and the damping pad strip 54 play the role of providing damping friction force, which can decelerate and buffer the downward moving cargo A.

[0028] In this embodiment, a fixing plate 3 is fixedly connected to the unloading plate 14. A photoelectric sensor 4 is fixed to the fixing plate 3 by screws. The photoelectric sensor 4 is used to sense whether the cargo A is significantly biased to the side of the unloading plate 14. A pushing assembly is provided on the side of the unloading plate 14. The pushing assembly includes an electric push rod 7 fixed to the unloading plate 14 by screws, a connector 71 fixed to the electric push rod 7 by screws, a sliding rod 8 that slides through the unloading plate 14 and the connector 71, and a pushing plate 9 fixed to one end of the sliding rod 8 by screws. When the photoelectric sensor 4 senses that the cargo A is biased to the side of the unloading plate 14, the electric push rod 7 changes from an extended state to a shortened state. The connector 71, the sliding rod 8 and the pushing plate 9 move, and the pushing plate 9 pushes the cargo A to prevent the cargo A from biasing to the side of the unloading plate 14.

[0029] In this embodiment, the connector 71 includes a cuboid base block e and a vertical rod f. The electric push rod 7 is connected to the base block e, and the sliding rod 8 passes through the vertical rod f. The electric push rod 7 and the sliding rod 8 are parallel. The sliding rod 8 is perpendicular to the push plate 9. The sliding rod 8 and the vertical rod f are reinforced by hand-tightening screws. Under the drive of the electric push rod 7, the position of the push plate 9 can be changed.

[0030] In this embodiment, the drive roller 22 is located between adjacent first unloading rollers 15, and the inclined cross-sections of the drive roller 22, the first unloading roller 15 and the second unloading roller 6 coincide, so that the goods A slide smoothly on the surfaces of the drive roller 22, the first unloading roller 15 and the second unloading roller 6.

[0031] In this embodiment, the damping roller 32 is located between the adjacent second unloading roller 6 and the stabilizing plate 51. The inclined cut surfaces of the second unloading roller 6 and the damping roller 32 coincide, so that the cargo A slides smoothly on the surfaces of the second unloading roller 6 and the damping roller 32. The damping roller 32 increases the friction force, which can slow down the downward movement of the cargo A.

[0032] In this embodiment, the inclined surfaces of the damping pad strip 54 and the damping pad plate 53 are on the same inclined surface. The second unloading roller 6 includes a first inner shaft a1 and a first outer cylinder a2. The damping roller 32 includes a second inner shaft b1 and a second outer cylinder b2. The fixing strip 52 passes through the gap between adjacent first outer cylinders a2 and the gap between adjacent second outer cylinders b2, which is suitable for goods of different sizes and widths.

[0033] Working principle and usage process of this utility model:

[0034] When unloading cargo A from the vehicle manually, the operator moves cargo A onto the loading plate 141 and pushes cargo A. Cargo A slides on the surfaces of the first unloading roller 15 and the second unloading roller 6 within the inclined unloading plate 14, and cargo A slides onto the unloading plate 142, thus achieving the purpose of unloading cargo.

[0035] When cargo A slides down the unloading plate 14, the photoelectric sensor 4 senses whether cargo A is significantly biased to the side of the unloading plate 14.

[0036] When the photoelectric sensor 4 detects that the cargo A is biased towards the side of the unloading plate 14, the electric push rod 7 changes from the extended state to the shortened state, the connecting piece 71, the sliding rod 8 and the push plate 9 move, and the push plate 9 pushes the cargo A to prevent the cargo A from biasing towards the side of the unloading plate 14.

[0037] If cargo A is heavy and there is a situation where cargo A is stopped inside the unloading plate 14, when the drive motor 21 starts, it causes the drive roller 22 to rotate clockwise, that is, along... Figure 1 The d1 direction of the drive roller 22 rotates, and the cargo A sliding in the unloading plate 14 is subjected to the deflection force brought by the rotation of the drive roller 22, which can accelerate the falling speed of cargo A and prevent cargo A from stopping and stopping in the center position in the unloading plate 14.

[0038] The damping motor 31 operates, causing the damping roller 32 to rotate counterclockwise, i.e., along... Figure 1The damping roller 32 rotates in the d2 direction and has an anti-slip damping pad on its outer surface, which can apply damping force to the cargo A to achieve the purpose of decelerating the cargo A.

[0039] In addition, the damping pad 53 and the damping strip 54 provide damping friction, which can slow down and buffer the downward movement of the cargo A.

[0040] In summary: The unloading rack is designed to apply downward force and damping friction force to the cargo. The drive motor 21 drives the drive roller 22 to rotate, and the cargo is subjected to the deflection force brought by the drive roller 22, which can accelerate the speed of the cargo falling. The designed damping roller 32, damping pad 53 and damping pad strip 54 play the role of providing damping friction force, which can slow down and buffer the downward movement of cargo A.
