Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle transportation, in particular to a loading device. BACKGROUND

[0002] In the process of loading a lighting vehicle into a transport vehicle, a direct hoisting method or a method of setting a temporary base plate combined with a traction mechanism is usually adopted.

[0003] The direct hoisting method mainly relies on large hoisting machinery such as cranes, which has the advantage of simple operation and can quickly complete the loading. However, this method requires high technical requirements for the operator, and the hoisting point position and hoisting angle need to be accurately calculated to avoid damage to the equipment. At the same time, when the large equipment moves in the air, it is affected by factors such as wind force and mechanical stability, and the safety risk is relatively large. Once an accident occurs, it may cause equipment damage or even personnel casualties.

[0004] Another method, i.e. setting a temporary base plate and a traction mechanism, has relatively complicated steps. First, a flat temporary base plate needs to be laid to create a stable transition platform, and then a traction mechanism is used to slowly move the lighting vehicle onto the transport vehicle. Although this method reduces the risk of direct mechanical stress on the equipment, it increases the time for preparation and disassembly work. At the same time, the laying of the base plate and the traction process of the lighting vehicle require close cooperation between the operators, which is physically demanding and requires high skills and endurance from the operators. Its safety is relatively lower than that of direct hoisting, because any small mistake can cause the base plate to slide or the traction to lose control. CONTENT OF THE UTILITY MODEL

[0005] Therefore, the present application provides a loading device to solve the problem of difficulty in loading a lighting vehicle.

[0006] In order to achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] A loading device, comprising a liftable scissor frame and a drive machine for driving the scissor frame to lift, a roller is arranged on the upper frame of the scissor frame, the roller is rotationally connected to the upper frame and the shaft of the roller is perpendicular to the moving direction of the lighting vehicle, and the upper surface of the roller exceeds the upper surface of the upper frame to contact the bottom of the lighting vehicle.

[0008] Optionally, the drive machine is a hydraulic oil cylinder.

[0009] Optionally, the roller is arranged in at least two rows on the upper frame in the moving direction of the lighting vehicle.

[0010] Optionally, the rollers are of the same specification and have the same installation height on the upper frame.

[0011] Optionally, a brake is arranged on the upper frame, and a height of the brake exceeds an upper surface of the upper frame, so as to contact with a chassis of the lighting vehicle.

[0012] Optionally, a rubber pad is arranged on an upper surface of the brake.

[0013] Optionally, the brake is arranged at a front end of the upper frame.

[0014] Optionally, a plurality of casters are arranged at a bottom of the lower frame of the scissor frame.

[0015] Optionally, a plurality of foot cups are arranged at the bottom of the lower frame of the scissor frame, and the foot cups are threadedly connected to the lower frame, and the foot cups are rotated to adjust a height of the lower frame.

[0016] Compared with the prior art, the present application has at least the following beneficial effects:

[0017] 1. The scissor frame can stably support the lighting vehicle to a certain height, until the height is consistent with a height of a carriage of a loading vehicle, and then a towing mechanism such as a tractor is used to tow the lighting vehicle to complete loading, so that the safety of loading can be ensured while reducing the amount of manual labor. The arrangement of the rollers can facilitate smooth movement of the lighting vehicle.

[0018] 2. The arrangement of the brake can prevent the lighting vehicle from rolling by the friction between the brake and the lighting vehicle, thereby improving the safety during loading.

[0019] 3. The arrangement of the foot cup can adjust the scissor frame to a horizontal state before loading. DETAILED DESCRIPTION

[0025] The application will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of the application: unless otherwise specified, the meaning of "a plurality of" is two or more. "Include", "contain", "have" and the like expressions also mean "not limited to" (some units, components, materials, steps, etc.).

[0027] The terms such as "upper", "lower", "left", "right", "intermediate" and the like referred to in the application are generally indicative of the relative position relationship for the purpose of intuitive understanding with reference to the drawings, and are not an absolute limitation on the position relationship in the actual product.

[0028] A loading device for lighting vehicles, referring to Figure 1 and Figure 2 , comprising a scissor frame 1 that can be lifted and a drive machine 2 for driving the scissor frame 1 to lift. Wherein the scissor frame 1 comprises an upper frame and a lower frame, and is connected by cross connecting rods to form a stable structure. The upper frame and the lower frame of the scissor frame 1 are the same rectangular frame, and the drive machine 2 is selected as a hydraulic cylinder.

[0029] The upper frame of the scissor frame 1 is provided with rollers 3, which are rotatably connected to the upper frame, and the shaft direction is perpendicular to the moving direction of the lighting vehicle. In order to facilitate the movement of the lighting vehicle, the upper surface of the roller 3 exceeds the upper surface of the upper frame, so as to contact the bottom of the lighting vehicle, so as to reduce the friction and improve the moving efficiency when the lighting vehicle moves.

[0030] Further, in order to ensure the stability of the lighting vehicle during movement, the rollers 3 are provided with at least two rows on the upper frame along the moving direction of the lighting vehicle. And all the rollers 3 are uniform in specification, and the installation height on the upper frame is also uniform, so as to ensure that all the rollers 3 can stably contact the bottom of the lighting vehicle, thereby ensuring the stability of the lighting vehicle during loading.

[0031] The upper surface of the upper frame is also provided with a brake 4. In this embodiment, the brake 4 can be provided as a flat plate structure, which is higher than the upper surface of the upper frame, and is used to contact the chassis of the lighting vehicle, so as to fix the position of the lighting vehicle by friction, and prevent it from sliding.

[0032] Further, the upper surface of the brake 4 is provided with a rubber pad to increase the friction and improve the braking effect.

[0033] In this embodiment, the brake 4 is located at the front end of the upper frame so that the lighting vehicle can brake quickly and accurately when it moves to the correct position.

[0034] The lower frame of the scissor lift 1 is equipped with multiple casters 5, which are distributed at the four corners of the lower frame to facilitate the movement of the loading device.

[0035] In addition, multiple foot cups 6 are installed at the bottom of the lower frame. In this embodiment, four foot cups 6 are installed, each arranged inside the caster 5. The foot cups 6 are perpendicular to the lower frame and are installed on the lower frame by threaded connection. The height of each corner of the lower frame can be adjusted by rotating the foot cups 6. After the loading device moves to the designated loading position, the lower frame is first adjusted to be level using the foot cups 6 before the lighting cart is moved onto the loading device.

[0036] The implementation principle of this application embodiment is as follows: Before loading, the loading device is first pushed to the designated loading position, and then the four foot cups 6 are rotated to adjust the loading device to a horizontal state to ensure the stability of the loading process. Then, the lighting cart is towed to the loading position until the lighting cart moves directly above the loading device, at which point the front end of the lighting cart chassis corresponds to the brake 4 of the loading device.

[0037] The hydraulic cylinder is then driven to lift the upper frame, and roller 3 contacts the bottom of the lighting vehicle, raising it upwards. The hydraulic cylinder stops when the height of the lighting vehicle is consistent with the height of the loading vehicle's cargo box.

[0038] Finally, a winch is used to move the lighting cart into the carriage. During the movement of the lighting cart, roller 3 rolls to ensure smooth movement. During this process, care should be taken to utilize the lighting cart's own braking system to prevent it from slipping, and the loading process is complete.

[0039] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
