[0002] A semitrailer is a trailer with an axle placed behind the center of gravity of the vehicle and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. A semitrailer is generally a three-axle semitrailer, which is divided into many types such as 11-meter warehouse semitrailer, 13-meter warehouse semitrailer, low-bed semitrailer, etc. It is a heavy-duty transport vehicle connected to the semitrailer head through a traction pin.

[0003] Some semi-trailers are separated from the bucket and placed in the corresponding area through the traditional hydraulic support structure. Since the traditional hydraulic support structure and the bottom of the bucket are mostly fixed structures, there is a lack of flexible rotation structure. At the same time, the bucket after separation is placed unreasonably, which hinders the movement of other mobile structures. In the absence of a tractor, it is difficult and laborious to move. Therefore, there is a lack of a support structure to replace the rolling structure to solve the above situation. Therefore, a semi-trailer bucket support device is proposed to solve the above problem. Summary of the invention

The fixed plate and the top horizontal plate of the Z-shaped plate are threaded through the same long screw, and one end of the long screw is rotatably installed in the middle position of the top surface of the U-shaped frame, and a roller is rotatably installed in the U-shaped frame.

[0008] Preferably, the movable seat is movably connected to one end of the clamping rod through a movable pin, and one end of the clamping rod is threadedly connected with a fastening nut.

[0009] Preferably, the U-shaped end surface of the U-shaped steel plate is flush with the horizontal plane, and the inner side of the U-shaped steel plate and one side of the middle part of the vertical clamping rod are in contact with each other.

[0010] Preferably, two Z-shaped plates are provided, and the two Z-shaped plates are respectively located outside the corresponding square hole steel cylinders.

The bearing 19 is assembled in the cylindrical frame 2, and the inner ring of the bearing 19 is assembled with one end of the shaft 3. The other end of the shaft 3 is welded to the middle position of the top surface of the circular plate 18, and two U-shaped steel plates 6 are symmetrically welded on the annular surface of the circular plate 18. Two four-sided connecting platforms 8 are symmetrically installed at the bottom of the circular plate 18, and one end of the square hole steel cylinder 17 is vertically installed on the end surface of the two four-sided connecting platforms 8. A hydraulic push rod 16 is installed in the square hole steel cylinder 17;

[0026] The rolling structure includes a roller 12, a Z-shaped plate 13, a long screw 9 and a fixed plate 10. One end of the bottom horizontal plate of the Z-shaped plate 13 is fixedly connected to the inner side of one end of the telescopic rod of the corresponding hydraulic push rod 16 through a ring sleeve 15, and one end of the fixed plate 10 is vertically installed on one side of the vertical plate in the middle of the Z-shaped plate 13. The fixed plate 10 and the top horizontal plate of the Z-shaped plate 13 are threaded through the same long screw 9, and one end of the long screw 9 is rotatably installed in the middle position of the top surface of the U-shaped frame 11, and the roller 12 is rotatably installed in the U-shaped frame 11.

[0027] The movable seat 4 is movably connected to one end of the clamping rod 5 through a movable pin, and one end of the clamping rod 5 is threadedly connected to a fastening nut 7, which is movably connected to one end of the clamping rod 5 through the movable seat 4, so that the clamping rod 5 can be rotated to one side to separate from the U-shaped steel plate 6; the U-shaped end surface of the U-shaped steel plate 6 is flush with the horizontal plane, and the U-shaped steel plate 6 and the middle side of the vertical clamping rod 5 are in contact with each other, and the fastening nut 7 is rotated to move up along the clamping rod 5 with an external thread and finally squeezed on the U-shaped surface at the bottom of the U-shaped steel plate 6, so as to achieve the effect of fixing the connected circular plate 18; the Z-shaped plate 1 There are two Z-shaped plates 13, and the two Z-shaped plates 13 are respectively located outside the corresponding square hole steel cylinder 17, so as to achieve the effect of symmetrical distribution installation; the ring sleeve 15 is assembled on the inner side of one end of the telescopic rod of the corresponding hydraulic push rod 16, and one end of the telescopic rod of the hydraulic push rod 16 is installed in the middle of the circular surface of the round steel plate 14, which is conducive to the round steel plate 14 touching the ground; the top surface of the fixed plate 10 and the top horizontal plate surface of the Z-shaped plate 13 are both provided with internal threaded through holes, and the two internal threaded through holes are located on the same vertical central axis, so as to facilitate the vertical threaded connection and penetration of the long screw 9.

[0028] When the present invention is in use, since the semi-trailer tractor and the bucket plate 1, i.e., the bucket, are not separated in use, the corresponding hydraulic push rods 16 in the two square hole steel cylinders 17 are firstly activated by the built-in control device of the vehicle body, so that the hydraulic push rods 16 are in an extended state and the round steel plate 14 at one end of the telescopic rod is pressed against the ground, and the pressing is firm. At this time, the semi-trailer tractor and the bucket plate 1 are separated, so as to achieve the effect of supporting the separation of the bucket plate 1 and facilitating the subsequent docking and installation.

[0029] When the parking area of ​​the bucket plate 1 is unreasonable and there is an obstruction to other mobile structures and the tractor is not there, first, the long screw 9 is rotated under the joint action of the threaded Z-shaped plate 13 and the fixed plate 10, so that one end of the long screw 9 pushes the U-shaped bar frame 11 and the rotatably installed roller 12 against the ground. At the same time, under the action of the continuous rotation of the long screw 9, the round steel plate 14 is slightly separated from the ground, and the bottom of one end of the bucket plate 1 is supported by the roller 12 and the connected parts after separation, thereby realizing the function of replacing the supporting structure, which is convenient for the movement and adjustment of the bucket after separation;

[0030] Then, an external pulling structure such as a rope is used to pull the separated end of the bucket plate 1, and the bottom of the separated end of the bucket plate 1 is rotated and interlaced through the bearing 19 and the shaft rod 3 and the circular plate 18 and the bottom part connected thereto, so that one end of the bucket plate 1 is pulled in the pulling direction. At the same time, the above operation is performed under the coordinated action of the roller 12, which is conducive to coordinating and flexibly separating the direction of one end of the tractor bucket, so as to achieve the effect of better separating the moving direction of the tractor bucket according to needs.
