Description

Technical Field

[0001] The utility model relates to the field of semi-trailers, in particular to a flatbed semi-trailer with legs that can be used as columns. Background Art

[0002] Semi-trailers are mainly used to transport large-sized goods that are large in volume and not easily disassembled, such as excavators, etc. The fence type is more suitable for transporting fresh goods, such as vegetables, fruits, etc.

[0003] It is found in the process of using the existing flatbed semi-trailers that: the flatbed semi-trailers can only transport some box-shaped items. When it is necessary to transport some pipe-shaped items or log-shaped items, there are no protective structures on both sides of the vehicle frame, which easily causes the pipe-shaped items or log-shaped items to roll off the flat vehicle frame. Moreover, the outer protruding area on both sides of the flat vehicle frame is relatively large, and the function of high-strength support cannot be achieved. For this reason, a flatbed semi-trailer with legs that can be used as columns is proposed. Summary of the Utility Model

[0004] In view of the problems existing in the above-mentioned existing flatbed semi-trailers, the present utility model is proposed.

[0005] Therefore, the purpose of the present utility model is to provide a flatbed semi-trailer with legs that can be used as columns, which solves the problems raised in the background art.

[0006] In order to achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A flatbed semi-trailer with legs that can be used as columns, including a vehicle frame. A plurality of uniformly distributed fixed sleeves are fixedly arranged on both sides of the vehicle frame. A column is slidably inserted into each of the plurality of fixed sleeves. At the bottom of the vehicle frame and corresponding to the positions of the plurality of fixed sleeves, there are oil cylinders. One end of each oil cylinder is hinged to the bottom of the vehicle frame, and the other end of the oil cylinder is hinged to the column wall of the column.

[0008] Preferably, an oil cylinder seat is fixedly arranged at the bottom of the vehicle frame. The base of the oil cylinder is hinged to the oil cylinder seat through an oil cylinder seat pin.

[0009] Preferably, a piston seat is fixedly arranged on the column wall of the column. The end of the piston rod of the oil cylinder is hinged to the piston seat through a piston pin.

[0010] Preferably, a support foot is fixedly arranged at the lower end of the column.

[0011] Furthermore, a column pin is inserted into the side wall of the fixed sleeve, and a column hole matching the column pin is formed in the column wall of the column.

[0012] Preferably, the number of the fixing sleeves and the number of the columns on both sides of the frame are both three, and the upper ends of the fixing sleeves and the columns are both arranged to protrude upward from the upper surface of the frame or the upper ends of the fixing sleeves and the columns are both arranged flush with the upper surface of the frame.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The utility model is provided with a fixed sleeve, a column and an oil cylinder. When the oil cylinder is connected to the oil circuit, the end of the piston rod of the cylinder will push the column downward or upward, so that the column moves inside the fixed sleeve. When the lower end of the column contacts the ground, the frame can be firmly supported to increase the strength of the frame. When the upper end of the column is lifted upward, the fixed sleeve and the column can act as a protective structure to prevent pipes or logs from rolling off the frame, so that the frame has a variety of forms and can be used as a log transport semi-trailer or a flatbed semi-trailer.

[0015] 2. The utility model provides a column latch on the fixed sleeve. When the column is lowered or raised, the column latch cooperates with the column sockets at the upper and lower ends of the column respectively, thereby limiting the position between the fixed sleeve and the column and increasing the use strength of the column.

[0016] In summary: the frame has a variety of forms, and can be used as a log transport semi-trailer or a flatbed semi-trailer. Compared with ordinary flatbed semi-trailers, the transport medium is more diverse, and it can transport containers, various logistics bulk goods, logs, pipes and other long items. Compared with conventional semi-trailers, the outriggers are positioned to the side, which not only ensures the strength, but also can be used as columns to achieve the transition between multiple states.

[0025] An embodiment of the present utility model discloses a flat semi-trailer with legs that can serve as columns.

[0026] Embodiment 1

[0027] The present utility model provides a flat semi-trailer with legs that can serve as columns as shown in Figures 1-3 , including a frame 1. Three evenly distributed fixed sleeves 2 are fixedly provided on both sides of the frame 1. Columns 3 are slidably inserted inside the three fixed sleeves 2. Support legs 9 are fixedly provided at the lower ends of the three columns 3. When the support legs 9 contact the ground, the stability of the contact between the columns 3 and the ground can be increased. The upper ends of the fixed sleeves 2 and the columns 3 are both provided protruding upward from the upper surface of the frame 1; oil cylinders 4 are provided at the bottom of the frame 1 and corresponding to the positions of the three fixed sleeves 2. One end of the oil cylinder 4 is hinged to the bottom of the frame 1, and the other end of the oil cylinder 4 is hinged to the column wall of the column 3.

[0028] When the oil cylinder 4 is connected to the oil circuit, the end of the piston rod of the oil cylinder 4 will push the column 3 downward or upward, causing the column 3 to move inside the fixed sleeve 2. When the lower end of the column 3 contacts the ground, the frame 1 can be firmly supported at this time, increasing the strength of the frame 1. When the upper end of the column 3 is lifted upward, at this time, the combined action of the fixed sleeve 2 and the column 3 can serve as a protective structure to prevent pipe-like items or log-like items from rolling off the frame 1, enabling the frame 1 to have multiple forms, which can be used as a log transportation semi-trailer or a flat semi-trailer.

[0029] In order to enable the oil cylinder 4 to be hinged to the frame 1 and the column 3, as shown in Figure 3 , an oil cylinder seat 5 is fixedly provided at the bottom of the frame 1. The base of the oil cylinder 4 is hinged to the oil cylinder seat 5 through an oil cylinder seat pin 6; a piston seat 7 is fixedly provided on the column wall of the column 3. The end of the piston rod of the oil cylinder 4 is hinged to the piston seat 7 through a piston pin 8.

[0030] Finally, in order to increase the stability between the fixed sleeve 2 and the column 3, as shown in Figure 1As shown, a column pin 10 is inserted into the side wall of the fixed sleeve 2, and a column jack 11 that cooperates with the column pin 10 is formed in the column wall of the column 3. When the column 3 descends or ascends, the column pin 10 cooperates with the column jacks 11 at the upper and lower ends of the column 3 respectively, so as to limit the position between the fixed sleeve 2 and the column 3 and increase the service strength of the column 3.

[0031] Embodiment 2

[0032] As Figure 4 shown, the difference between Embodiment 2 and Embodiment 1 is that the upper ends of the fixed sleeve 2 and the column 3 are flush with the upper surface of the vehicle frame 1. After the column 3 moves downward, the upper surface of the vehicle frame becomes completely smooth without any protruding structure.

[0033] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
