Description

Technical Field

[0001] The present application relates to the technical field of loading, unloading and transporting of special military materials, and in particular to a non-powered air-floating lifting and transporting device. Background Art

[0002] With the development of domestic logistics and transportation industry, container transportation has gradually become the mainstream trend of cargo transportation. The loading and unloading of large containers has gradually matured, but the rapid loading and unloading of small wooden boxes, especially various forms of wooden boxes used for military products, is still a problem. The ground bull currently used in the market cannot meet the use requirements because of its minimum height, and its overall size and weight are large, which makes it impossible to use it on special transportation vehicles, which brings many inconveniences to the rapid loading and unloading of this type of wooden boxes.

[0003] Especially when the special transport vehicle has a rear door, the wooden box is heavy and has a large friction with the bottom of the carriage. Currently, multiple people are required to first pry up the wooden box with a crowbar, and then push it into (outside) the vehicle little by little to complete loading (unloading). This method of loading and unloading wooden boxes not only has high labor costs, but also low efficiency, and can no longer meet the current logistics support needs. Summary of the invention

[0004] The present application proposes a non-powered air-floating lifting and transporting device, which has the advantages of not only simple and ingenious structure, but also novelty and strong practicality, and is used to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a non-powered air-floating lifting and transporting device comprises: the air-floating lifting equipment, the top surface of the air-floating lifting equipment is provided with a cover plate, foldable handles are fixedly installed on both sides of the long sides of the air-floating lifting equipment, the foldable handles have a foldable function, the interior of the air-floating lifting equipment is symmetrically fixed with a supporting top plate on one side of the cover plate, the interior of the air-floating lifting equipment is provided with a roller group module, an air path control module, and an air bag module, the side surface of the supporting top plate is evenly provided with holes compatible with the air path control module, the side surface of the supporting top plate is evenly provided with sliding holes compatible with the roller group module, wherein the air path control module is connected to the air bag module inside the supporting top plate through the hole, and the internal parts of the roller group module are rotatably installed inside the supporting top plate through the sliding holes.

[0006] Through the above-mentioned structural setting and the above-mentioned mechanism setting, under the premise of ensuring the overall strength, not only the weight of the equipment is reduced, which is convenient for transportation, but also the operating difficulty is reduced and it is convenient for control. The use of this device for loading and unloading can greatly improve the efficiency and enhance the practicality of the device. The device is modularly designed, and specifically consists of multiple modules such as a roller group module, an air path control module, an airbag module, and related accessories and fittings. It can be designed according to specific needs based on user selection.

[0007] Furthermore, the roller group module includes a roller support frame and rollers. The roller group module is movably installed inside the support top plate. The roller support frame is similar to a U-shaped mechanism. Rollers are installed in a linear array inside the roller support frame and rotate evenly. A rotating shaft is provided in the middle of the roller between the two walls of the roller support frame. Guide plates are provided on both sides of the roller support frame. A limiting shaft is evenly fixedly connected to the roller support frame and the guide plate in a linear array. The end of the limiting shaft is located inside the sliding hole. The limiting shaft slides in the sliding hole. The sliding hole limits the sliding direction of the limiting shaft. Threaded holes are provided at both ends of the roller support frame.

[0008] Through the above-mentioned structural arrangement, by pulling the device as a whole, the roller generates friction with the contact surface, causing the roller to rotate on the outer ring of the shaft, so that the device can be moved inside the carriage. By placing a wooden box on the top of the device and performing some steps to lift up the wooden box, the device can be pulled so that a single person can easily push the wooden box from the special vehicle to the platform.

[0009] Furthermore, the roller assembly module is composed of a roller support frame, rollers, a rotating shaft, a limiting shaft, a guide plate and standard parts.

[0010] Furthermore, the air circuit control module is fixedly installed on one side of the cover plate and is located between the supporting top plates. One side of the air circuit control module is fixedly connected to an air intake connector. One side of the air circuit control module is fixedly connected to a connecting air pipe between one side of the air intake connector and the airbag module.

[0011] Through the above-mentioned structural setting, the air inlet connector receives external gas, and through the module control of the air circuit control module, the gas is transmitted to the airbag module through the connecting air pipe, and the lifting and lowering of the air floating lifting device is controlled by the air circuit control module.

[0012] Furthermore, the air circuit control module is composed of a control box, various valves, pipe joints and air pipes, wherein the air inlet is connected to the vehicle-mounted air tank through the air control cabinet, and the air outlet is connected to the airbag module.

[0013] Furthermore, the airbag module is fixedly installed between the roller support frame and the support top plate.

The airbag is fixedly installed between one side of the roller support frame and the inner wall of the support top plate. Plugs are fixedly installed on both sides of the airbag. A connecting air pipe is fixedly connected between the airbag and the air path control module, and the pressure plate is fixedly installed at the threaded hole position on one side of the roller support frame.

[0014] Through the above-mentioned structural setting, compressed gas flows into the airbag through the connecting air pipe, and the airbag inflates to push the roller group module outward, so that the limit shaft is located inside the sliding hole for sliding. The sliding hole provides redundant space for the roller group module to slide up and down. The airbag expands under the action of compressed gas, causing the supporting top plate to lift, and then lifts the air floating lifting and handling equipment, thereby lifting the wooden box.

[0015] Furthermore, the airbag module is cooperatively connected with the roller assembly module and corresponds one-to-one with the roller assembly module. The roller assembly module is cooperatively connected with the support top plate through a limit shaft and standard parts, and the airbag module corresponds one-to-one with the support top plate.

[0016] Furthermore, mounting holes and auxiliary holes are provided on both sides of the roller support frame, and the rotating shaft and the limiting shaft are respectively installed in the mounting holes and the auxiliary holes.

[0017] Through the above-mentioned structural setting, by controlling the parameters of the sliding hole, the minimum height and the lifting height of the air floating lifting and transporting setting can be achieved.

[0018] Furthermore, the support top plate and the cover plate are fixed by bolts, and the cover plate can be used in conjunction with two sets but not limited to two sets of support top plates (including roller assemblies).

[0019] The present application provides a non-powered air-floating lifting and transporting device, which realizes functions such as easy loading and unloading by setting structures such as a roller group module, an air circuit control module, and an air bag module. The device is light in weight, strong in lifting ability, simple in structure, low in cost, high in loading and unloading efficiency, and strong in practicality.

[0038] The specific working principle is as follows. When unloading is required, the device is placed under the wooden box. There is a pad under the wooden box, and there is an empty space for placing the device. The air circuit control module 3 is started, and the compressed gas will enter the interior of the air circuit control module 3 from the gas storage tank through the air inlet joint 31. The compressed gas flows into the air bag 41 through the connecting air pipe 32. The air bag 41 expands under the action of the compressed gas, causing the support top plate 13 to be lifted, so that the roller group module 2 is squeezed out of the interior of the support top plate 13, and then the air floating lifting and handling equipment is lifted, thereby lifting the wooden box and creating a distance between the wooden box and the ground. Since the device is provided with rollers 22, a single person can easily push the wooden box from the special vehicle compartment to the platform, and then close the air circuit control module 3, the air bag is depressurized, the device is reset, and then the device is taken out from under the wooden box to complete the unloading. The device can be used to reverse the unloading operation during the loading process of the wooden box, and no further description will be given.
