Description

Technical Field

[0001] This utility model belongs to the field of vehicle transportation technology, and in particular relates to an automatic and rapid vehicle loading and unloading device. Background Technology

[0002] With the increasing number of outdoor support and emergency rescue operations, various equipment needs to be transported using modular shelters and trucks. Some equipment requires being moved outside the shelter for ground operations. Currently, forklifts and cranes are frequently used for loading and unloading equipment. Another type of equipment is bolted in place, making it impossible to move it outside the vehicle.

[0003] Traditional equipment installation primarily relies on bolt fixing. While this method offers the advantage of reliability, it is cumbersome, time-consuming, and labor-intensive, requiring ample space for tool operation. Furthermore, this method often results in equipment operating inside the vehicle, hindering the rapid dissipation of noise, exhaust fumes, and heat. For cranes and forklifts moving equipment outside their vehicles, securing them mainly involves bundling and tightening. This method is less reliable, demands high skill levels from personnel, and requires significant operating space.

[0004] Therefore, there is a need for a device that can move equipment outside the vehicle for operation without relying on cranes or forklifts. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device that can move equipment outside the vehicle for operation without relying on cranes or forklifts.

[0006] To solve the above-mentioned technical problems, the specific technical solution of this utility model is as follows:

[0007] An automatic and rapid vehicle loading and unloading device includes a support rail 1, a slider 2, a lifting motor 6, a hand crank mechanism 7, an equipment support 8, and a multi-stage lifting device 9.

[0008] The bracket guide rail 1 includes a fixed bracket 11 and a linear guide rail 12; the bottom of the fixed bracket 11 is fixedly connected to the bottom of the vehicle, and the top is provided with the linear guide rail 12; the slider 2 is slidably connected to the linear guide rail 12, and the multi-stage lifting device 9 is provided above the slider 2.

[0009] The multi-stage lifting device 9 includes a chain 91, a primary gantry 92, a secondary gantry 93, and a tertiary gantry 94; the primary gantry 92 is slidably connected to the secondary gantry 93, and the secondary gantry 93 is slidably connected to the tertiary gantry 94; the lifting motor 6 and the hand crank mechanism 7 are fixed on the primary gantry 92, and both are used to drive the chain 91 to move, thereby causing the primary gantry 92, the secondary gantry 93, and the tertiary gantry 94 to slide relative to each other and send the equipment to the ground; the equipment support 8 is fixedly connected to the primary gantry 92.

[0010] Furthermore, shock absorbers 3 and cables 4 are installed under the vehicle to support the equipment bracket 8.

[0011] Furthermore, the mounting bracket 11 is fixed to the bottom of the vehicle with bolts.

[0012] Furthermore, it also includes a limit pin 5, used to limit the forward and backward movement of the equipment.

[0013] This utility model has the following advantages: the device can stably fix the equipment inside the vehicle during transportation, and can quickly transfer it to the ground when it is necessary to get off the vehicle to work. This can greatly reduce the number of steps required by personnel, realize automated transfer, shorten equipment preparation time, improve the efficiency of emergency rescue in the field, and has high practical application value.

Detailed Implementation

[0021] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, the loading and unloading device of this embodiment consists of a support rail 1, a slider 2, a shock absorber 3, a cable 4, a limit pin 5, a lifting motor 6, a hand crank mechanism 7, an equipment support 8, and a multi-stage lifting device 9.

[0023] The bracket guide rail 1 includes a fixed bracket 11, a linear guide rail 12, a limit pin hole 13, and a fixing bolt hole 14;

[0024] The bottom of the fixed bracket 11 is fixedly connected to the bottom of the vehicle, and the top is provided with a linear guide rail 12; the slider 2 is slidably connected to the linear guide rail 12, and the multi-stage lifting device 9 is provided above the slider 2.

[0025] The multi-stage lifting mechanism 9 includes a chain 91, a primary gantry 92, a secondary gantry 93, and a tertiary gantry 94; the primary gantry 92 is slidably connected to the secondary gantry 93, and the secondary gantry 93 is slidably connected to the tertiary gantry 94; the lifting motor 6 and the hand crank mechanism 7 are fixed on the primary gantry 92, which are used to drive the chain 91 to move, thereby causing the primary gantry 92, the secondary gantry 93, and the tertiary gantry 94 to slide relative to each other and send the equipment to the ground;

[0026] The equipment support 8 is fixedly connected to the first-level gantry 92; shock absorbers 3 and cables 4 are installed on the underside of the vehicle to support the equipment support 8.

[0027] When the vehicle is in motion, the primary gantry 92, the secondary gantry 93, and the tertiary gantry 94 are overlapped.

[0028] like Figure 2 As shown, the fixed bracket 11 is fixed to the bottom of the vehicle through the fixed bolt hole 14. The limit pin hole 13 is used in conjunction with the limit pin 5 to achieve the function of front and rear limit fixation. The linear guide rail 12 is used in conjunction with the slider 2 to allow the equipment to move horizontally along the guide rail and be pushed out of the vehicle.

[0029] like Figure 3 As shown, the equipment bracket 8 is seated inside the vehicle via shock absorbers 3, mitigating various impacts and vibrations caused by uneven road surfaces. The cable 4 can quickly tighten and secure the equipment to the vehicle body, preventing lateral swaying and increasing friction through vertical tightening. The limit pin 5, utilizing a spring pin, can be quickly inserted and removed, limiting the equipment's forward and backward movement.

[0030] like Figure 4-5 As shown, the lifting motor 6 serves as the drive unit for the entire equipment, driving the lifting device to achieve vertical lifting by rotating forward and reverse. The hand crank mechanism 7 serves as a backup mechanism, allowing for manual lifting of the equipment in case the lifting motor fails or there is no power.

[0031] like Figure 6 As shown, the equipment is connected to the multi-stage lifting mechanism 9 via the equipment support 8. The lifting motor 6 drives the chain 91, which in turn drives the first-stage gantry 92, the second-stage gantry 93, and the third-stage gantry 94 to send the equipment to the ground.

[0032] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered to fall within the protection scope of the present invention.
