Description

Technical Field

[0001] The utility model belongs to the technical field of trailers, in particular to a flexible direction-changing traction mechanism of a wood grabber trailer. Background Art

[0002] Trailers are a common means of transportation, mainly used to move disabled vehicles from accident sites or other specific locations to designated locations. Trailers can also be equipped with various equipment and tools, such as cranes, scrapers, etc., for repair or transportation. Trailers are usually equipped with a traction mechanism to tow a full trailer to ensure that the motor vehicle and the vehicle are connected to each other.

[0003] When using existing equipment, the overall length of the trailer is too long, which requires constant angle adjustment during cornering. At the same time, the trailer is easily overturned due to changes in the center of gravity during loading and unloading. Therefore, we propose a flexible directional traction mechanism for the log grabber trailer. Utility Model Content

Through a supporting mechanism and an adjusting mechanism, the utility model solves the problem that the angle needs to be constantly adjusted during the turning process due to the overall length of the trailer being too long, and the problem that the trailer is easily overturned due to the change of the center of gravity during the loading and unloading process.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] According to the above technical solution, by fixing the blocking plate at the front end of the main frame, it is possible to prevent the cargo from hitting the cab due to inertia.

[0008] Furthermore, the outer wall of the blocking plate is fixedly connected to a plurality of fixing plates, the outer walls of a plurality of the fixing plates are fixedly connected to connecting plates, the outer wall of the connecting plates is fixedly connected to a supporting beam, the outer wall of the supporting beam is fixedly connected to the outer wall of the main frame, and the outer wall of the supporting beam is fixedly connected to a plurality of triangular fixing plates.

[0009] Through the above technical solution, the structural strength of the front end of the trailer is increased by connecting the supporting crossbeam to the fixing plate and connecting the triangular fixing plates at both ends of the supporting crossbeam.

[0010] Furthermore, the outer wall of the triangular fixing plate is fixedly connected to a connecting column, the outer wall of the connecting column is rotatably connected to a supporting column, the outer wall of the supporting column is fixedly connected to a supporting foot, and the outer wall of the supporting column is fixedly connected to a baffle.

[0011] With the above technical solution, by fixing the connecting column on the triangular fixing plate, the supporting column can be easily moved when loading cargo, thereby preventing the trailer from tipping over.

[0012] Furthermore, the outer wall of the support column is fixedly connected to a connecting seat, the outer wall of the connecting seat and the outer wall of the triangular fixing plate are both fixedly connected to a second connecting column, and the outer wall of the second connecting column is rotatably connected to a second connecting ring.

[0013] Through the above technical solution, the connecting column 2 is fixed on the connecting seat and the triangular fixing plate, and the telescopic rod is connected to the support column through the connecting ring 2.

[0014] Furthermore, the outer wall of the second connecting ring is fixedly connected to a telescopic rod, the outer wall of the telescopic rod is fixedly connected to a connecting ring, and the outer wall of the connecting ring is rotatably connected to the outer wall of the second connecting column.

[0015] With the above technical solution, the possibility of the trailer rolling over can be reduced by performing mechanical movement through the telescopic rod.

[0016] Furthermore, the outer wall of the main frame is fixedly connected to an arc-shaped baffle, the outer walls of the triangular positioning plate and the arc-shaped baffle are both fixedly connected to positioning columns, the outer wall of the positioning column is rotatably connected to a positioning ring, and the outer wall of the positioning ring is fixedly connected to a hydraulic rod.

[0017] Through the above technical solution, the hydraulic rod connects the arc baffle and the triangular positioning plate through the positioning ring, so that when turning, the hydraulic rod can perform mechanical movement to enable the trailer to pass through the turn quickly.

[0018] Furthermore, the outer wall of the triangular positioning plate is fixedly connected to a hollow tube, the outer wall of the hollow tube is fixedly connected to a fixing block, and the outer wall of the fixing block is fixedly connected to the outer wall of the arc-shaped baffle.

[0019] Through the above technical solution, the arc baffle is fixed in front of the main frame, and the arc baffle is connected to the hollow tube through the fixing block.

[0020] Furthermore, the inner wall of the hollow tube is slidably connected to an extension rod, the outer wall of the extension rod is fixedly connected to a pull ring, the inner wall of the hollow tube and the inner wall of the extension rod are provided with limiting holes, and the inner wall of the limiting hole is slidably connected to a clamping block.

[0021] Through the above technical solution, the trailer can be easily connected to vehicles of different types by moving the extension rod inside the hollow tube.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model is provided with a hydraulic rod, and the outer walls of the arc baffle and the triangular positioning plate are fixed with the same positioning column at the same time, and are connected to the positioning rings at both ends of the hydraulic rod. Therefore, when the trailer turns, the hydraulic rods on both sides will be mechanically moved to limit the turning radius of the trailer. Because the outer wall of the triangular positioning plate is connected to the fixed column and is connected to the main frame, the triangular positioning plate will rotate slightly along the fixed column when turning, so as to achieve mechanical movement through the hydraulic rod, thereby preventing the situation where the angle needs to be constantly adjusted during the turning process due to the overall length of the trailer being too long.

[0024] 2. The utility model provides a support column, and the support columns on both sides are rotated along the connecting column connected to the outer wall of the triangular fixing plate, so that the support foot fixed at the other end of the support column contacts the ground. At the same time, the clamping strip is pulled out from the inside of the porous support column, and the porous support column is moved to the ground along the limit ring and then clamped with the clamping strip. During the loading process, the telescopic rod is connected to the triangular fixing plate through the connecting seat. When one side of the trailer is heavy during loading, the pressure on the support column can be relieved by the mechanical movement of the telescopic rod to prevent the support column from being bent by the weight. The support foot is brought into contact with the ground through the rotation of the support column, which prevents the problem of the trailer tipping over due to the change of center of gravity during loading and unloading.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
