Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers, in particular to a bulkhead semi-trailer for transportation. Background Art

[0002] The bulkhead semi-trailer is used to transport simple goods, such as daily necessities like vegetables, fruits, clothes, and electrical appliances, and also plays a very important role in power engineering and communication engineering. Most small equipment for engineering is transported by the bulkhead semi-trailer. However, the volume of the fence of the traditional bulkhead semi-trailer is fixed and it is difficult to achieve expansion. Moreover, when loading and transporting large and relatively dangerous goods such as pipes or bars, the inertia caused by sudden braking will make the goods rush towards the cab, posing a life threat to the driver; when loading or unloading goods on the bulkhead semi-trailer, it is necessary to open the fence, but it is difficult to quickly fix the position after the fence is opened, resulting in relatively inconvenient loading and unloading. Summary of the Utility Model

[0003] An embodiment of the present disclosure relates to a bulkhead semi-trailer for transportation. By providing a movable sliding door and a protection component, the transportation and storage space of the semi-trailer can be expanded, and the movable fence can be used to increase the resistance of the goods moving forward to the cab, improving the protection for the driver.

[0004] In a first aspect of the present disclosure, there is provided a bulkhead semi-trailer for transportation, specifically including: a semi-trailer and a locking member; a chassis bracket is fixedly connected to the semi-trailer; a protection component is installed on the top surface of the chassis bracket; the protection component includes a fixed fence and a movable fence. The fixed fence is welded to the top surface of the chassis bracket, and a locking bracket member is welded to the outer end surface of the fixed fence. The movable fence is slidably clamped to the top surface of the chassis bracket and is connected by bolts. A locking rod member is welded to the outer end surface of the movable fence. Door panels are respectively clamped inside the fixed fence and the movable fence; a handle is welded to the door panel, and a support wheel is rotatably connected to the bottom of the door panel through a shaft. The support wheel, the handle, and the door panel form a complete movable sliding door; the locking member is clamped to the handle and is composed of a locking bracket and a locking rod, and the locking rod penetrates through the inside of the locking bracket.

[0005] In at least some embodiments, the locking bracket member includes an upper locking plate and a lower locking plate, and insertion holes are respectively formed inside the upper locking plate and the lower locking plate, and a second card slot is formed inside the lower locking plate.

[0006] In at least some embodiments, a receiving groove is formed at the bottom of the door panel, and the support wheel is connected to the inside of the receiving groove through a shaft. After pulling the handle to drive the movement of the door panel, the support wheel can slide on the top surface of the chassis bracket after being exposed. Both ends of the shaft of the support wheel are clamped to the bottom surface of the door panel to play a supporting role, and the support wheel can reduce the friction between the door panel and the chassis bracket.

[0007] In at least some embodiments, the latch rod lock includes an upper lock block and a lower lock block. A threaded hole B is formed inside the upper lock block, and a socket is formed inside the upper lock block. The threaded hole B is adapted to a threaded cap. A first card slot and a slot are formed inside the lower lock block. The slot is located directly below the threaded hole B. A handle is inserted into the socket.

[0008] In at least some embodiments, a threaded cap is welded to the top end of the latch rod. A screwing plate is welded to the outer wall of the threaded cap. The threaded cap is threadedly engaged in the threaded hole A inside the latch bracket. After the latch bracket is clamped between the handles, the latch rod is connected to the latch bracket, and the two handles can be locked to complete the fastening of the door panel.

[0009] In at least some embodiments, a fixed door stop is provided on the right end face of the movable fence. A rotating shaft sleeve is rotatably connected to the middle of the fixed door stop through a shaft. A gear is welded to the outside of the rotating shaft sleeve. The gear is engaged with a rack. A rotating door stop is provided on the top surface of the fixed door stop. The bottom of the rotating door stop is fixedly connected to the rotating shaft sleeve. The rack is slidably clamped inside the fixed door stop, and a pull rope is fixedly connected to the top surface of the rack.

[0010] The utility model provides a semi-trailer for transporting goods in a barn-shaped structure, which has the following beneficial effects:

[0011] When in use, after pulling the handle to drive the door panel to move, the door panel can cooperate with the movable fence to move, so that the transportation and storage space of the semi-trailer can be expanded. When transporting goods with large inertia and high danger such as pipes or bars at the rear of the movable fence, the movable fence can be used to increase the resistance of the goods moving forward to the cab, improving the protection of the driver.

[0012] In addition, the threaded cap is threadedly engaged inside the latch bracket. After the latch bracket is clamped between the handles, the latch rod is connected to the latch bracket, and the two handles can be locked to complete the fastening of the door panel. When the latch rod and the latch bracket are used separately, by inserting the latch bracket into the jack, the left door panel and the fixed fence can be locked. When the left handle is pulled, it can be clamped into the socket. The threaded cap can be connected to the inside of the threaded hole B, and the bottom end of the latch rod is inserted into the slot. In this way, the latch rod can be fixedly connected to the movable fence through the latch rod lock, so that the door panel can be fixed open, facilitating unloading or loading.
