DETAILED DESCRIPTION

[0020] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example:

[0022] like Figure 1-Figure 5 As shown, a detachable carriage comprises a carriage 1 placed on a truck frame, two groups of lifting legs respectively arranged at the front and rear ends of the carriage 1 for detaching the carriage 1 from the truck, and a roller structure arranged at the rear end of the carriage 1 and used to cooperate with a ground ox to pull the carriage 1; each group of lifting legs comprises two, respectively arranged on the left and right sides of the carriage 1, and there are also two roller structures, respectively arranged on the left and right sides to ensure balance; the lifting legs comprise a lifting cylinder arranged on the outside of the carriage 1, and the outer sleeve of the lifting cylinder is provided with a leg slide plate 4 for protecting the legs from deformation due to force; one end of the cylinder body of the lifting cylinder is fixed to the bottom of the groove of the leg slide plate 4, and the piston rod of the lifting cylinder extends from the open end of the leg slide plate 4; the roller structure comprises a fixing part and a roller 203 arranged at the bottom of the fixing part; the carriage 1 close to the front end is the front end, and the other end is the rear end.

[0023] When the lifting legs are in a vertical state, the bottom of the roller 203 extends downward beyond the bottom of the lifting legs.

[0024] A ball head weighing sensor 5 is arranged at the end of the piston rod of the lifting cylinder.

[0025] The ball head weighing sensor 5 is fixedly connected to the support plate 6 to improve the stability of the lifting cylinder when it is supported on the ground after the ball head weighing sensor 5 is installed; if the ball head weighing sensor 5 and the support plate 6 are set, when the lifting leg is in a vertical state, the bottom of the support plate 6 extends downward beyond the bottom of the lifting leg.

[0026] There are two types of fixing parts. The first type: a structure with a fixing function, as follows: the fixing part includes a support column 204 fixedly connected to the bottom of the carriage 1, and a connecting part 201 is connected to the bottom of the support column 204. There are two connecting parts 201, which are set at a distance on the left and right. The connecting part 201 is connected to a roller shaft 202, and the roller 203 is connected to the roller shaft 202.

[0027] The second type: a structure having the function of lifting and lowering the roller 203; as follows: the fixing member comprises a telescopic sleeve (2) fixedly connected to the carriage (1); a telescopic connecting member (201) is arranged inside the telescopic sleeve (2); the connecting member (201) is connected to a roller shaft (202); and the roller (203) is connected to the roller shaft (202).

[0028] The retractable connecting member 201 is provided in the following ways: 1. There are two connecting members 201, which are spaced apart from each other and connected at the top through a top plate; a roller cylinder is provided in the telescopic sleeve 2, the bottom of the roller cylinder is connected to the top plate, the connecting member 201 is connected to a roller shaft 202, and the roller 203 is connected to the roller shaft 202. 2. At least two pin holes are provided in the vertical direction on the two opposite side plates of the telescopic sleeve 2, and at least one pin hole is provided at the position of the pin hole on the telescopic sleeve 2 corresponding to the two connecting members 201. The pin holes of the connecting member 201 and the telescopic sleeve 2 correspond to each other, and a latch is inserted in the pin hole. When the connecting member 201 is pulled out downward to extend out of the telescopic sleeve 2 or when the connecting member 201 is pushed upward to be in the telescopic sleeve 2, the latch is inserted into the pin hole to fix the height of the roller 203.

[0029] At the position of the leg slide plate 4 at the bottom of the car 1, there is an extension structure along the left and right direction of the car 1, which enables the leg slide plate 4 to extend from the bottom of the car 1 to the outside of the car 1 and turn from a horizontal state to a vertical state. The extension structure includes an extension cylinder 3 connected to the leg slide plate 4; the extension structure in this application adopts a utility model patent previously submitted by our company, with application number 2023228474569, and its name is a floor-standing leg of a box-type freight vehicle; the combination of leg pants, telescopic parts and rotating structure is the same as the extension structure of this application.

[0030] The carriage 1 includes a bottom plate 102 and a door 101 located at the rear end of the carriage 1; the bottom of the door 101 is hinged to the bottom plate 102, a first fixed seat 701 is fixedly installed on the upper front side of the door 101, a second fixed seat 702 is fixedly installed on the upper surface of the rear end of the bottom plate 102, the first fixed seat 701 is hinged to one end of the rear door cylinder 7, and the other end of the rear door cylinder 7 is hinged to the second fixed seat 702; the first fixed seat 701 and the second fixed seat 702 are located in the same vertical plane.

[0031] A lock catch 703 is fixedly installed at the rear end of the side door of the carriage 1 close to the door 101, and a locking rod 704 that can cooperate with the lock catch 703 is installed on the side of the door 101 corresponding to the lock catch 703; when the door 101 is closed under the action of the rear door cylinder 7, the locking rod 704 is stuck in the lock catch 703.

[0032] By arranging a liftable support leg on the outside of the car body 1 and arranging a roller 203 at the rear end of the car body, the liftable support leg is raised to separate the car body from the frame, and then retracted to the bottom higher than the bottom of the roller, the roller cooperates with the ground bull that pulls the front end of the car body, and the ground bull cooperates with the roller to drive and turn the car body. This solution can conveniently and quickly separate the car body from the frame and transport the car body, thereby improving the transportation efficiency and high safety. A car body door is arranged, and the entire car body is moved to the unloading site by the ground bull, and the car body door is opened and closed by the rear door cylinder, the bottom of the car body door is hinged to the bottom plate, and the rear door cylinder is extended until the top of the car body door abuts against the ground for easy unloading.

[0033] Working process: In general, in the initial state, the lifting legs are horizontally located at the bottom of the car body 1 or vertically located at the side of the car body. If they are located at the bottom, the extension structure extends them and rotates them to a vertical state; the lifting cylinder rises to separate the car body 1 from the frame, and then retracts to a bottom higher than the bottom of the roller. The roller cooperates with the ground bull that pulls the front end of the car body, and the ground bull cooperates with the roller to drive and turn the car body; finally, the door is opened to unload the cargo.
