Technical field
The invention belongs to air-powered lifting technical field, be specifically related to a kind of air-powered lifting device for safety lifting carrying.
Background technology
The mode that general lifting is relatively commonly used has: carry out lifting, the direct lifting of electric cylinder etc. by hydraulic-driven scissors mechanism.When needs hoisting force is large, general with the lifting of hydraulic-driven scissor, but this mode needs the parts such as Hydraulic Pump, easy leakage of oil and the uncleanly problem of work-site; And by the direct lifting of electric cylinder, not only cost is higher, and hoisting force is large not.
Summary of the invention
The object of this invention is to provide a kind of air-powered lifting device, solve the problem that hoisting force has not greatly and just the easy leakage of oil of hydraulic-driven.
Technical scheme of the present invention is: a kind of air-powered lifting device, comprises lifting platform 2, balloon-type cylinder 1, pilot bar 3, wear-resisting copper sheathing 4, lift protecting device 6, bearing pin 7, pilot bar limiting stopper 8 and fixed mount 9; Lifting platform 2 upper surface directly contacts with load weight, and upper surface and lifting platform 2 bottom surface of balloon-type cylinder 1 are connected, and the lower surface of balloon-type cylinder 1 is fixedly connected with the top of fixed mount 9; Wear-resisting copper sheathing 4 is fixed on fixed mount 9 top, and pilot bar 3 top is fixedly connected with the fixed cover of lifting platform 2 bottom surface through after wear-resisting copper sheathing 4, is fixed with pilot bar limiting stopper 8 bottom pilot bar 3; When main gas circuit is balloon-type cylinder 1 air feed, balloon-type cylinder 1 inflation, thus promote lifting platform 2 with pilot bar 3 together along the inner side upward movement of wear-resisting copper sheathing 4.Lift protecting device 6 is the loop configuration of a side opening, is rotationally connected by bearing pin 7 and fixed mount 9, rotates lift protecting device 6, its upper end is contacted with the fixed cover of lifting platform 2 bottom surface, realizes supporting role.
Beneficial effect: a kind of bench board that can realize air-powered lifting function is installed in the present invention additional on existing shipping platform, realizes the functions such as the lifting of load weight, transport.Adopt balloon-type cylinder, it bears axis, radial capacity is strong, can realize the flexibility transmission of bearing capacity, effective adjustment of stroke and the efficient control to vibrations; Mechanical safety device is adopted to ensure the safety of whole lifting transportation.

Detailed description of the invention
For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1-2, a kind of air-powered lifting device of the present invention, comprises a lifting platform 2, three balloon-type cylinders 1, pilot bar 3, wear-resisting copper sheathing 4, copper sheathing permanent seat 5, lift protecting device 6, bearing pin 7, pilot bar limiting stopper 8 and fixed mounts 9;
Lifting platform 2 is main bearing member, directly contacts with load weight, and upper surface and lifting platform 2 bottom surface of balloon-type cylinder 1 are connected, and lower surface is fixedly connected with the top of fixed mount 9; Wear-resisting copper sheathing 4 is fixed on fixed mount 9 top by copper sheathing permanent seat 5, and pilot bar 3 top fixed cover that is rear through wear-resisting copper sheathing 4 and lifting platform 2 bottom surface is connected, and is fixed with pilot bar limiting stopper 8 bottom pilot bar 3; When main gas circuit is balloon-type cylinder 1 air feed, balloon-type cylinder 1 inflation, thus promote lifting platform 2 with pilot bar 3 together along the inner side upward movement of wear-resisting copper sheathing 4.Lifting platform 2 after balloon-type cylinder 1 inflation with pilot bar 3 together upward movement, pilot bar limiting stopper 8 completes mechanical position limitation work after contacting with the bottom of copper sheathing permanent seat 5, now lifting platform 2 no longer upward movement.Lift protecting device 6 can along bearing pin 7 manual rotation, after lifting platform 2 completes lifting, and the handle of manual rotation lift protecting device 6; its inner ring semicircle contacts with pilot bar 3; upper end contacts with the fixed cover of lifting platform 2 bottom surface, plays a supporting role, and completes lifting protection work.
Air-powered lifting plant running process for safety carrying of the present invention is:
Opening main gas circuit during work starts as system air feed, and balloon-type cylinder 1 inflation provides bearing force upwards, thus promotes lifting platform 2 upward movement being connected in its upper surface.While lifting platform 2 upward movement, the pilot bar 3 that is connected thereon can be driven along the inner side together upward movement of wear-resisting copper sheathing 4.Pilot bar 3 upward movement, until after the pilot bar limiting stopper 8 be connected bottom it contacts with copper sheathing permanent seat 5, copper sheathing permanent seat 5 limits its upward movement.So far, lifting mechanism completes whole work of upwards lifting.After lifting work completes; manual rotation is arranged on the lift protecting device 6 on fixed mount 9; its inner ring semicircle is contacted with the cylinder of pilot bar 3; its upper and lower two surfaces may be stuck between lifting platform 2 and fixed mount 9; in case lifting transport midway gas circuit breaks down or the factor such as Uneven road causes balloon-type cylinder 1 to leak gas, thus lifting platform is made to lose bearing force.
After lifting transport terminates, first rotating lifting fender guard 6 handle, makes its inner ring depart from pilot bar 3.Control gas circuit is closed, and bellows cylinder 1 starts to queue contraction, thus the lifting platform 2 be connected thereon is moved downward until reset.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
