Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, and specifically relates to an open-top carriage with a simple cantilever loading and unloading crane. Background Technique
[0002] The carriage is the main functional part of a freight truck for carrying goods. Whether it is a heavy or light freight truck, due to the chassis structure, the surface of the carriage floor is generally relatively high from the ground (more than 0.7 meters). Without the availability of cranes, forklifts, conveying mechanisms, etc., it is relatively strenuous labor to carry goods onto the carriage or unload goods from the carriage.
[0003] Professional cranes and truck-mounted cranes are special-purpose vehicles. Generally, they have a relatively large lifting capacity, and the overall dimensions of the vehicles are also relatively large. They are not very suitable for narrow environments or situations where the weight of a single piece of goods is relatively light but the quantity is relatively large, and the lifting cost is relatively high.
[0004] When encountering special goods such as oil drums, cement bags, gypsum bags, and swill buckets, it is also not convenient for personnel to directly handle them. Even when wearing labor protection supplies, there are still problems such as inconvenient operation or inability to work for a long time. Content of the Utility Model

[0009] A further improvement lies in that: the cross-section of the support arm is in an I shape, and the lifting device is connected to the sliding grooves on both sides of the support arm.
[0010] A further improvement is that the lifting device includes a moving trolley and an electric hoist arranged at the bottom of the moving trolley, and the two side walls of the moving trolley extend upward and are respectively provided with pulleys adapted to the slide groove.
[0011] A further improvement is that the rotating shaft is slidably connected to the horizontal slide rail through a hinge device, and the rotating shaft can rotate around the hinge device.
[0012] A further improvement is that the hinge device includes a hinge body and a slider, the slider is slidably arranged on a horizontal slide rail, and the hinge body is sleeved on the rotating shaft and connected to the slider through a connecting rod.
[0013] A further improvement is that the slider is provided with a sliding locking mechanism.
[0014] A further improvement is that the hinge body is provided with a rotation locking mechanism.
[0015] A further improvement is that: the height of the front plate is higher than that of the rear plate, two horizontal slide rails are provided, and both horizontal slide rails are located at a position where the front plate is higher than the rear plate.

Two horizontal slide rails 21 are provided, and both horizontal slide rails 21 are located at a position where the front plate 2 is higher than the rear plate 3.
[0032] See also Figure 3As shown, the crane support 5 has a triangular structure, comprising a vertically arranged rotation axis 51, a horizontally arranged support arm 52, and an inclined connecting arm 53. Specifically, a reinforcement block 54 is provided at the junction of the support arm 52 and the connecting arm 53. The support arm 52 has an I-shaped cross-section, and the lifting device 6 is connected to the slide slots 55 on both sides of the support arm 52.
[0033] See also Figure 4 As shown, the lifting device 6 includes a mobile trolley 62 and an electric hoist 61 mounted at the bottom of the trolley 62. The two side walls 63 of the trolley 62 extend upward and are each provided with a pulley 64 that fits within the chute 55. The electric hoist can move horizontally on the chute, covering the width of the carriage. It is electrically driven, and the lifting and lowering of the cargo is accomplished by the pulling force of the electric hoist.
[0034] See also Figure 5 and Figure 6 As shown, the rotating shaft 51 is slidably connected to the horizontal slide rail 21 through the hinge device 7, and the rotating shaft 51 can rotate around the hinge device 7. The crane bracket can move around the rotating shaft, covering the left and right areas of the car, and is manually pushed and pulled.
