Abstract
The utility model relates to a pneumatic hook type automatic switch for rear box board of tipper, which is an automatic switch device of the rear box board of tipper. One end of the a control valve(3) and the gas storing tank(1) are connected by the pipeline(2-1), and the other end of the control valve and the cylinder(4) are connected by the pipeline(2-2). The left end of a piston rod is fixedly provided with a piston(9-1) positioned in the cylinder(4), and the right end of the piston rod(9) is articulated with the lower end of a rotating body(5), and the upper end of the rotating body is fixedly positioned on the shaft(6), and the lower end of the hook(8) is fixedly positioned on the shaft(6). Two bearing seats(7) are fixedly arranged under the packing case(11), and two bearings(10) are respectively positioned in the two bearing seats(7). Two ends of the shaft(6) are respectively positioned in the two bearings(10). The utility model is of a simple structure and convenient use, whose rear box board can automatically start when in unloading and can automatically close after the unloading. Moreover, the utility model is safe and reliable with few reconstructing cost, which is applicable for the starting and closing of the rear box board of different tipper.
Description
Technical field: the utility model is the recloser of dumping car rearing-box plate.
Background technology: generally all need before at present dumping car is unloaded each time rearing-box plate to be opened and could realize automatic the unloading with manpower.During manpower switch rearing-box plate, the workman needs up and down vehicle body several times, labor strength height not only, and in the work of switch rearing-box plate, exist safety hazard, work efficiency is also low.
Summary of the invention: the utility model is the pneumatic clamping hook type recloser of a kind of dumping car rearing-box plate of development.It can realize the Push And Release of chaufeur automatic guidance rearing-box plate in operator's compartment.The utility model comprises container 11, storage tank 1, it also comprises pipeline 2, control cock 3, cylinder 4, rotor 5, axle 6, bearing seat 7, grab 8, piston rod 9, bearing 10; One end of control cock 3 is connected by pipeline 2-1 with storage tank 1, the other end of control cock 3 is connected by pipeline 2-2 with cylinder 4, the left end of piston rod 9 is fixed with piston 9-1, piston 9-1 is arranged in the cylinder 4, and the lower end of the right-hand member of piston rod 9 and rotor 5 is hinged, and the upper end of rotor 5 is fixed on the axle 6, the lower end of grab 8 is fixed on the axle 6, two bearing seats 7 be fixed on container 11 below, two bearings 10 are separately positioned in two bearing seats 7, the two ends of axle 6 are separately positioned in two bearings 10.The utility model is simple in structure, easy to use, rearing-box plate can self-opening during unloading, unloading back rearing-box plate again can SELF CL, and safe and reliable, can be when new car dispatches from the factory direct mount or on existing car, reequip, improvement expenses is few, is applicable to the open and close of multiple dumping car rearing-box plate.
Description of drawings: Fig. 1 is a front view of the present utility model, and Fig. 2 is a upward view of the present utility model, and Fig. 3 is the connection structure scheme drawing of connector 9-2 and rotor 5 in the specific embodiment two.
The specific embodiment one: present embodiment is made up of storage tank 1, pipeline 2, control cock 3, cylinder 4, rotor 5, axle 6, bearing seat 7, grab 8, piston rod 9, bearing 10, container 11.One end of control cock 3 is connected by pipeline 2-1 with storage tank 1, the other end of control cock 3 is connected by pipeline 2-2 with cylinder 4, the left end of piston rod 9 is fixed with piston 9-1, piston 9-1 is arranged in the cylinder 4, the right-hand member of piston rod 9 is fixed with attaching parts 9-2, the lower end of attaching parts 9-2 and rotor 5 is hinged, the upper end of rotor 5 is fixed on the centre of axle 6, the lower end of two grabs 8 is fixed on the axle 6, and be positioned at the both sides of rotor 5, two bearing seats 7 be fixed on container 11 below, two bearings 10 are separately positioned in two bearing seats 7, the termination, two ends of axle 6 is separately positioned in two bearings 10.
The specific embodiment two: connector 9-2 is connected by bolt 12, packing ring 13, nut 14 with the lower end of rotor 5 in the present embodiment, but this connection mode hand rotation body 5 when air-actuator breaks down makes grab 8 rotate the opening and closing that realize rearing-box plate 11-1, and other composition is identical with the specific embodiment one with annexation.
Principle of work: when dumping car is unloaded, chaufeur is by connecting the master cock of control cock 3, select to open and turn round, control cock 3 energisings, the gas of storage tank 1 enters the right chamber of cylinder 4 behind the automotive ignition, promote piston rod 9 and move to left, the grab 8 that rotor 5 drives on axle 6 and the axle 6 clockwise rotates, and turns to till rearing-box plate 11-1 opens fully until grab 8.After the unloading, selection is closed and is turned round, control cock 3 is oppositely switched on, gas enters the left chamber of cylinder 4, promoting piston rod 9 moves to right, the grab 8 that rotor 5 is driven on axle 6 and the axle 6 rotates counterclockwise, and relies on the upper end of grab 8 that rearing-box plate 11-1 is held up, till grab 8 cuts out rearing-box plate 11-1 and pin fully.
