Abstract
A traction pin self-locking system comprises a tubular column, a fixing plate, a plurality of installation plates and a traction pin. The installation plates are arranged on the fixing plate in parallel from top to bottom. A round hole is formed in the same position of each installation plate, and the diameters of the round holes are identical. The tubular column is arranged in the round hole in the uppermost installation plate. Two clamping openings which are in a spiral shape are symmetrically formed in the side wall of the tubular column. A column body of the traction pin is inserted in the round holes of all the installation plates. A square pull ring is welded to the upper portion of the column body of the traction pin. The inner diameter of the pull ring is slightly larger than the outer diameter of the tubular column. By the adoption of the traction pin self-locking system, the traction pin can be locked automatically without manual operation, and simpleness, fastness and safety are achieved.
Description
Technical field
The present invention relates to fork truck technical field, it is specifically related to a kind of traction pin self-locking system.
Background technology
Electrically propelled traction vehicle is mechanical means conventional during handling works, and its power resources are exactly the storage battery being assemblied on tow tractor. Along with social development, the high-power tow tractor of Large Copacity gets more and more, therefore loading is more and more heavier, but container to be still connected with headstock by tow tractor by traction pin, but because container loading is heavier, existing a lot of traction pin is deviate from sometimes automatically, so it is dead to need will to draw lock, and current traction pin substantially all to be leaned on manual lock dead, extremely bother.
Summary of the invention
It is an object of the invention to be to provide a kind of traction pin self-locking system, automatically traction pin can be carried out lock dead, it is not necessary to manually, simple and fast safety.
It is an object of the invention to be achieved through the following technical solutions: it comprises tubing string, retaining plate, mounting plate, traction pin, described retaining plate is arranged with some mounting plates downwards in parallel from upper, the identical position of each mounting plate all has the circular hole of same diameter, topmost the circular hole place of a mounting plate is provided with a tubing string, described tubing string sidewall symmetry has two bayonet sockets, described bayonet socket is in the shape of a spiral, described traction pin body is inserted in the circular hole of each mounting plate, being welded with square draw ring above traction pin body, draw ring internal diameter is more bigger than tubing string external diameter.
It is dead that traction pin can be carried out lock by the present invention automatically, it is not necessary to manually, simple and fast safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is present configuration schematic perspective view;
Fig. 3 is the structural representation of tubing string of the present invention.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical scheme of the present invention is further described in detail.
Embodiment: as illustrated in the accompanying drawings from 1 to 3, it comprises tubing string 1, retaining plate 2, mounting plate 3, traction pin 4, described retaining plate 2 is arranged with some mounting plates 3 downwards in parallel from upper, each identical position of mounting plate 3 all has the circular hole of same diameter, topmost the circular hole place of a mounting plate 3 is provided with a tubing string 1, described tubing string 1 sidewall symmetry has two bayonet sockets, described bayonet socket is in the shape of a spiral, described traction pin 4 cylinder is inserted in the circular hole of each mounting plate 3, being welded with square draw ring above traction pin 4 cylinder, draw ring internal diameter is more bigger than tubing string 1 external diameter.
The present invention is arranged on headstock by retaining plate, before lock is dead, traction pin is extracted, then stationary installation corresponding with mounting plate for container is put in the space between mounting plate, and then traction pin is inserted from tubing string, and the bayonet socket by traction pin draw ring alignment tubing string, decontrol hand, the draw ring of traction pin will go to downslide along bayonet socket automatically, realization is automatically locked, and draw ring is not easily deviate from, simple and safe.
Above-described embodiment is the one preferably scheme of the present invention, not the invention of this reality is done any restriction in form, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
