Abstract
Description
Technical Field
[0001] This invention relates to the field of cargo transportation equipment technology, and in particular to a rapid cargo loading and unloading device for road freight transportation. Background Technology
[0002] Road freight transport is the most widely used, flexible, and extensive mode of transport in my country's comprehensive logistics system, and it is widely applied in urban distribution, e-commerce logistics, less-than-truckload (LTL) freight, and container transshipment. The loading and unloading process is a critical node in road transport efficiency, directly impacting vehicle turnaround speed, logistics costs, and operational safety.
[0003] Currently, domestic road freight transport loading and unloading operations still generally adopt traditional methods: mainly relying on manual handling or using manual hydraulic trailers and forklifts to complete the work. However, manual and forklift operations are slow, and multi-layered goods, boxed goods, and bagged goods need to be handled piece by piece, which cannot be continuously transported. This results in long truck parking times, low vehicle turnover rates, and difficulty in meeting the needs of efficient operation of modern logistics. Summary of the Invention
[0004] The purpose of this invention is to provide a rapid loading and unloading device for road freight transportation, which aims to solve the problems of continuous transportation, long truck parking time, and low turnover rate caused by traditional manual handling of goods loading and unloading.
[0005] To achieve the above objectives, the present invention provides a rapid loading and unloading device for road freight transportation, comprising a mobile frame, an adjusting frame, a conveyor belt, an unloading roller plate, a loading plate, a feeding rod, and baffles; the adjusting frame is fixedly connected to the mobile frame and located on top of the mobile frame; the conveyor belt is mounted on the side of the adjusting frame away from the mobile frame; the unloading roller plate is fixedly connected to the adjusting frame and located on one side of the adjusting frame; the baffles are respectively mounted on both sides of the conveyor belt and the unloading roller plate; the loading plate is disposed on both sides of the adjusting frame; and the feeding rod is fixedly connected to the loading plate and located on the side of the loading plate away from the adjusting frame.
[0006] The adjusting frame includes a support frame, a hydraulic cylinder, and a buffer rod. The hydraulic cylinder is fixedly connected to the mobile frame and located at the top of the mobile frame. The support frame is fixedly connected to the output end of the hydraulic cylinder and to the conveyor belt, and is located between the conveyor belt and the hydraulic cylinder. The buffer rod is fixedly connected to the support frame and to the mobile frame, and is located between the mobile frame and the support frame.
[0007] The buffer rod includes a damping rod and a first spring. The damping rod is fixedly connected to the support frame and the mobile frame, and is located between the mobile frame and the support frame. The first spring is sleeved on the outside of the damping rod.
[0008] The unloading roller plate includes a roller plate body, a rubber plate, and an unloading seat. The roller plate body is fixedly connected to the support frame and is located on one side of the support frame. The rubber plate is fixedly connected to the roller plate body and is located on the side of the roller plate body away from the support frame. The unloading seat is fixedly connected to the rubber plate and is located at the bottom of the rubber plate.
[0009] The unloading seat includes an airbag, a second spring, and a base. The second spring is fixedly connected to the rubber plate and is located at the bottom of the rubber plate. The base is fixedly connected to the second spring and is located on the side of the second spring away from the rubber plate. The airbag is disposed on the side of the base close to the second spring.
[0010] The feeding plate includes a feeding plate body, a mounting frame, and a lifting chain. The lifting chain is disposed on both sides of the support frame, and the mounting frame is assembled on one side of the lifting chain. The feeding plate body is fixedly connected to the mounting frame and is located on one side of the mounting frame.
[0011] The feeding rod includes a telescopic cylinder and a push plate. The telescopic cylinder is fixedly connected to the feeding plate body and is located at the top of the feeding plate body. The push plate is fixedly connected to the output end of the telescopic cylinder and is located on one side of the telescopic cylinder.
[0012] This invention discloses a rapid loading and unloading device for road freight transportation. The movable frame moves the conveyor belt to the truck bed. The adjusting frame adjusts the height of the conveyor belt based on the truck bed height, ensuring the conveyor belt is level with the truck bed. During unloading, workers place the goods from the truck bed onto the conveyor belt. The conveyor belt rotates forward, transporting the goods towards the unloading rollers, where they are unloaded, thus achieving rapid unloading. During loading the truck bed, workers place the goods on the loading plate, which rises to lift the goods until they reach the loading platform. When the loading plate is aligned with the conveyor belt, the feeding rod moves to push the goods into the conveyor belt. The conveyor belt reverses direction to deliver the goods into the truck bed, thus achieving rapid loading of goods. During the loading and unloading process, this device only requires workers to assist in unloading the goods and does not require them to participate in the handling. It continuously transports goods by reversing the forward and reverse directions of the conveyor belt (which is achieved by controlling the rotation direction of the motor output). Compared with the traditional manual handling method, it can greatly improve the efficiency of loading and unloading goods, thereby solving the problems of continuous transportation, long truck parking time, and low turnover rate in traditional manual handling of goods.

Detailed Implementation
[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] Please see Figures 1 to 4 This invention provides a rapid loading and unloading device for road freight transportation, comprising a mobile frame 1, an adjusting frame 2, a conveyor belt 3, an unloading roller plate 4, a loading plate 5, a feeding rod 6, and a baffle 7; the adjusting frame 2 is fixedly connected to the mobile frame 1 and located on top of the mobile frame 1; the conveyor belt 3 is mounted on the side of the adjusting frame 2 away from the mobile frame 1; the unloading roller plate 4 is fixedly connected to the adjusting frame 2 and located on one side of the adjusting frame 2; the baffle 7 is respectively mounted on both sides of the conveyor belt 3 and the unloading roller plate 4; the loading plate 5 is disposed on both sides of the adjusting frame 2; and the feeding rod 6 is fixedly connected to the loading plate 5 and located on the side of the loading plate 5 away from the adjusting frame 2.
[0021] In this embodiment, the mobile frame 1 is used to move the conveyor belt 3 to the truck bed. The adjusting frame 2 adjusts the height of the conveyor belt 3 based on the height of the truck bed, so that the conveyor belt 3 is flush with the truck bed. When unloading goods, workers place the goods in the truck bed onto the conveyor belt 3. The conveyor belt 3 rotates forward to transport the goods to the unloading roller plate 4, and then unloads the goods through the unloading roller plate 4, thus achieving rapid unloading of goods. When loading the truck bed, workers place the goods on the loading plate 5. The loading plate 5 rises to lift the goods until the loading plate 5 is flush with the conveyor belt 3. When the conveyor belt is aligned, the feeding rod 6 moves to push the goods into the conveyor belt 3. The conveyor belt 3 then reverses to deliver the goods into the truck bed, thus achieving rapid loading of goods. During the loading and unloading process, this device only requires workers to assist in feeding the goods, eliminating the need for manual bending, lifting, or long-distance transport of goods. The conveyor belt 3 continuously transports goods by reversing forward and backward (achieved by controlling the rotation direction of the motor output). Compared with the traditional manual handling and loading / unloading method, this device can greatly improve the efficiency of loading and unloading goods, thereby solving the problems of continuous transport, long truck parking time, and low turnover rate caused by traditional manual handling and loading / unloading.
[0022] Furthermore, the adjusting frame 2 includes a support frame 21, a hydraulic cylinder 22, and a buffer rod 23. The hydraulic cylinder 22 is fixedly connected to the mobile frame 1 and is located at the top of the mobile frame 1. The support frame 21 is fixedly connected to the output end of the hydraulic cylinder 22 and is fixedly connected to the conveyor belt 3, and is located between the conveyor belt 3 and the hydraulic cylinder 22. The buffer rod 23 is fixedly connected to the support frame 21 and is fixedly connected to the mobile frame 1, and is located between the mobile frame 1 and the support frame 21.
[0023] In this embodiment, the hydraulic cylinder 22 serves as the lifting power source, fixed to the mobile frame 1 and remaining stationary. Its output end can extend and retract to drive the support frame 21 to rise or fall vertically. The support frame 21 is a rigid load-bearing structure, with its upper end directly supporting the conveyor belt 3 and its lower end connected to the output end of the hydraulic cylinder 22. This allows the lifting power of the hydraulic cylinder 22 to be transmitted to the conveyor belt 3, ensuring that the conveyor belt 3 remains horizontal, untilted, and undeformed during lifting. The buffer rod 23 provides buffer support at the moment the hydraulic cylinder 22 starts and stops lifting, and at the moment of impact when goods are placed, preventing the hydraulic cylinder 22 from bearing instantaneous rigid loads, reducing device vibration and noise, and improving lifting stability.
[0024] Furthermore, the buffer rod 23 includes a damping rod 231 and a first spring 232. The damping rod 231 is fixedly connected to the support frame 21 and the mobile frame 1, and is located between the mobile frame 1 and the support frame 21. The first spring 232 is sleeved on the outside of the damping rod 231.
[0025] In this embodiment, the damping rod 231 is used to absorb the vibration and impact energy generated during the lifting process, preventing the support frame 21 from shaking rapidly up and down; the first spring 232 is sleeved on the outside of the damping rod 231 and arranged coaxially with the damping rod 231. The two ends of the first spring 232 respectively abut against the support frame 21 and the moving frame 1, and are used to provide elastic support force: providing rebound buffer when the support frame 21 descends, and providing auxiliary pulling force when the support frame 21 rises. At the same time, it cooperates with the damping rod 231 to form a "spring vibration reduction + damping shock absorption" dual buffer structure, making the lifting process smoother, protecting the hydraulic cylinder 22 from impact damage, and extending the service life of the device.
[0026] Furthermore, the unloading roller plate 4 includes a roller plate body 41, a rubber plate 42, and an unloading seat 43. The roller plate body 41 is fixedly connected to the support frame 21 and is located on one side of the support frame 21. The rubber plate 42 is fixedly connected to the roller plate body 41 and is located on the side of the roller plate body 41 away from the support frame 21. The unloading seat 43 is fixedly connected to the rubber plate 42 and is located at the bottom of the rubber plate 42.
[0027] In this embodiment, the roller plate body 41 is a discharge output component, with multiple parallel freely rotating roller shafts installed inside. After the goods arrive, they can quickly roll across the roller shafts by gravity or the thrust of the conveyor belt 3, reducing the frictional resistance between the goods and the discharge roller plate 4. The rubber plate 42 is a flexible buffer component, fixed at the outermost discharge position of the roller plate body 41, i.e., the final sliding position of the goods, and is used to flexibly receive the goods. The unloading seat 43 is set at the bottom of the rubber plate 42, and is used to support the rubber plate 42 and unload, buffer, and disperse the impact force generated by the falling goods.
[0028] Furthermore, the unloading seat 43 includes an airbag 431, a second spring 432, and a base 433. The second spring 432 is fixedly connected to the rubber plate 42 and is located at the bottom of the rubber plate 42. The base 433 is fixedly connected to the second spring 432 and is located on the side of the second spring 432 away from the rubber plate 42. The airbag 431 is disposed on the side of the base 433 close to the second spring 432.
[0029] In this embodiment, the second spring 432 is an elastic buffer component, with its upper end directly connected to the bottom of the rubber plate 42. It is used to withstand the impact of the cargo and provide primary buffering, absorbing most of the falling impact force. The base 433 is a rigid support base that is fixed in place and is used to support the second spring 432 and the airbag 431, ensuring the stability of the overall structure. The airbag 431 is located below the rubber plate 42 and is filled with compressed air. It is used to provide secondary flexible pressure relief after the second spring 432 has buffered the impact, further absorbing the residual impact force, making the force on the rubber plate 42 more uniform and the sinking more gently, thus preventing the cargo from being damaged by hard impact.
[0030] Furthermore, the feeding plate 5 includes a feeding plate body 51, a mounting frame 52, and a lifting chain 53. The lifting chain 53 is disposed on both sides of the support frame 21, and the mounting frame 52 is assembled on one side of the lifting chain 53. The feeding plate body 51 is fixedly connected to the mounting frame 52 and is located on one side of the mounting frame 52.
[0031] In this embodiment, the lifting chain 53 is a lifting transmission component, symmetrically arranged on the left and right sides of the support frame 21. It is driven by a drive motor and sprocket to rotate clockwise or counterclockwise, thereby driving the mounting frame 52 to move up and down. The mounting frame 52 is a transition connecting frame, with one side fixed to the lifting chain 53 and rising and falling synchronously with the lifting chain 53. The other side is used to fix and install the feeding plate body 51, ensuring that the feeding plate body 51 does not shake or deviate during the lifting process. The feeding plate body 51 is a horizontal bearing plate used to place the goods to be loaded into the truck. It is driven to rise by the lifting chain 53 until the upper surface of the feeding plate body 51 is completely flush with the surface of the conveyor belt 3, preparing for the subsequent feeding rod 6 to push the material.
[0032] Furthermore, the feeding rod 6 includes a telescopic cylinder 61 and a push plate 62. The telescopic cylinder 61 is fixedly connected to the feeding plate body 51 and is located at the top of the feeding plate body 51. The push plate 62 is fixedly connected to the output end of the telescopic cylinder 61 and is located on one side of the telescopic cylinder 61.
[0033] In this embodiment, the telescopic cylinder 61 is the feeding power source, fixedly installed on the upper surface of the feeding plate body 51, and rises and falls synchronously with the feeding plate body 51. Its output end can perform horizontal telescopic movement. The push plate 62 is the pushing execution component, fixedly connected to the output end of the telescopic cylinder 61. After the feeding plate body 51 rises to be flush with the conveyor belt 3, the telescopic cylinder 61 extends, driving the push plate 62 to move in the horizontal direction, smoothly pushing the goods on the feeding plate body 51 into the interior of the conveyor belt 3, realizing semi-automatic feeding and further improving loading efficiency.
[0034] The above-disclosed embodiments are merely preferred embodiments of a rapid loading and unloading device for road freight transport, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
