The detachable gooseneck low-bed semi-trailer has a mechanical detachable gooseneck, an air detachable gooseneck, and a hydraulic detachable gooseneck.
The following is the operation process of the mechanical detachable gooseneck:
When preparing to remove the gooseneck, the tow pin must first be separated from the tow saddle. During operation, the front end of the gooseneck slides off the traction saddle mechanism and sequentially slides over inclined plane 2 and plane 1 adjacent to the traction saddle. As the height of the gooseneck decreases, the bottom corner of the front end of the semi-trailer is lowered to the ground and leans on the ground. When the tractor drives far enough away, the weight of the semi-trailer is supported by the wheels of the semi-trailer and the bottom corner of the front end of the semi-trailer, while the gooseneck is cantilevered and protrudes from the front end of the semi-trailer.
Then, remove the retaining ring and slide the connecting plate forward to disengage the pin 2 from the hole 2 completely. Next, put the retaining ring in the rear position to ensure that the front of the connecting plate is in the restrained position of the steel belt. After rotating the handle to retract the pins (one of them is in a clockwise direction), the tractor backs up, and the lower surface of the gooseneck arch structure successively contacts the inclined plane 1 and plane 2 of the tractor and slides upward. break away. When the tractor drives forward again, since the gooseneck is connected with the traction saddle, the tractor drags the gooseneck to separate it from the semi-trailer, and the semi-trailer is tilted on the ground.
When the semi-trailer is loaded, the previous operation process is reversed. The tractor drags the gooseneck backwards, causing the gooseneck to stop on the front end of the semi-trailer. At this moment, the rocker handle is in the release position, and the latch is ejected by the spring. The tractor moves backward, and the guide slope on the semi-trailer guides the protruding rod on the gooseneck to guide it into the correct position. As the lug moves rearward relative to the semi, the latch snaps at the lug from behind. The protruding rod is clamped in the correct position, and the gooseneck is orthogonally connected with the semi-trailer as a whole. Then, the gooseneck is separated from the traction saddle, and the tractor moves forward. As the tractor moves forward, the gooseneck repeats the camming motion with the tractor's inclined plane, so that as the front end of the gooseneck is lowered, the gooseneck rotates about an orthogonal axis in the area of the ledge. During this process, the tooth-shaped protrusion is inserted into the slot hole again, and the inclined plane b falls to be adjacent to the inclined plane a. The flange plate 2 inclined downward and inward on the gooseneck and the flange plate 1 inclined downward and inward at the front end of the semi-trailer can improve the alignment efficiency of the gooseneck and the semi-trailer. After the gooseneck is suspended, remove the retaining ring and manually slide the connecting plate backwards to insert it into the overhanging part of the front end of the pin shaft 2. When the gooseneck is lowered, the arcuate movement of the connecting plate will cause it to stop at the forward protruding part of the pin shaft 2 . Therefore, it is easy to slide the connecting plate back to the rear position, followed by putting the retaining ring back into the forward position. At this point, the connection between the gooseneck and the semi-trailer is completed. The tractor is backed up again, and the traction pin is connected with the traction saddle again, so that the whole detachable gooseneck low-bed semi-trailer and its loaded goods can travel at an appropriate height.
The mechanical detachable gooseneck low-bed semi-trailer has the main characteristics of simple structure and light weight due to its low manufacturing and operating costs, good reliability, and easy maintenance. The disassembly process is cumbersome, but it is widely used in long-distance transportation.
