Abstract
The utility model relates to an air-actuated automatic lock for the semi-trailer tractor seat, which comprises a handle, a handle retraction spring, a driver plate, a latch hook, a block for spacing the latch hook, a driver pin, a latch hook retraction spring, a cylinder control assembly installed at the end of the driver plate, and two cylinder spacing block at two sides of the driver plate. The utility model enables to realize the remote air-actuated opening of the lock and therefore decreases the labor strength for increasing the efficiency.
Description
(1) described technical field
The utility model belongs to the technical field of semi-dragging truck traction seat, the traction seat that particularly a kind of semi-dragging truck can pneumaticly be unblanked.
(2) background technology
The traction seat that existing semi-dragging truck all adopts manpower to unblank, when its weak point was that traction seat is unblanked, chaufeur must be walked out operator's compartment, implemented to the traction seat place to unblank, and returned the bridge operation vehicle then.And, manually unblank to require great effort very much, after using in the vehicle length time especially, the difficulty more of manually unblanking.
(3) summary of the invention
The utility model provides a kind of traction seat of remote controlled pneumatic auto-unlocking in order to overcome the shortcoming of requiring great effort of manually unblanking.
The utility model is realized by following measure:
The utility model discloses the traction seat that a kind of semi-dragging truck can pneumaticly be unblanked, comprise handle, handle pull back spring, driver plate, latch hook limiting stopper, latch hook, towing pin, latch hook pull back spring, in the end of driver plate the control cylinder assembly is installed, one cylinder limiting stopper is respectively arranged in the both sides of driver plate.
In order to adapt to pneumatic operation, handle is slick and sly surface.
Described control cylinder assembly comes driving handle and driver plate to move by air pressure, realizes auto-unlocking, and its master cock is installed in the operator's compartment.
Break away from car body at superimposed trailer, when needing traction seat to unblank, open the switch in the operator's compartment, make the control cylinder assembly under the effect of air pressure, driving handle moves to right, drive driver plate and latch hook limiting stopper and move to right, latch hook is opened under the effect of latch hook pull back spring, thereby realizes opening automatically of traction seat Locking Device.
Simultaneously, when malfunctioning, this wheel tractor traction seat still can adopt traditional manual mode to unblank pneumatic.
Therefore, traction seat of the present utility model can realize that remote control pneumatic unblanks, and has alleviated labour intensity, has improved efficient.
(4) description of drawings
Make specific description below in conjunction with accompanying drawing
As figure is the structural representation of looking up of the utility model traction
Among the figure, 1 control cylinder assembly, 2 handle pull back springs, 3 cylinder limiting stoppers, 4 handles, 5 latch hook limiting stoppers, 6 driver plates, 7 latch hooks, 8 towing pins, 9 latch hook pull back springs, 10 cylinder supports
(5) specific embodiment
Accompanying drawing has provided the structural representation of present embodiment.Present embodiment is to transform to form on the basis of hand traction seat.Traction seat of the present utility model is used to out semi-dragging truck, be on the basis of common single hook traction seat, in the end of driver plate 6 control cylinder assembly 1 is installed, one end of control cylinder assembly 1 is fixed on the driver plate 6, the other end is fixed on the traction seat by cylinder support 10, in the both sides of driver plate 6 a cylinder limiting stopper 3 is arranged respectively, simultaneously, handle 4 is changed system into slick and sly surface, to adapt to the pneumatic operation motion.Under gas pressure, driving handle is to move to right, and drives driver plate 6 and latch hook limiting stopper 5 and moves to right, and latch hook 7 is opened under the effect of latch hook pull back spring 9, thereby realizes opening automatically of traction seat Locking Device.
