Abstract
The utility model discloses a mobile-type composite jacking mechanism of an automobile elevator, which overcomes the problems of long cylinder stroke, high elevating sliding table, long elevating time, large overall weight, high cost and large energy consumption of a conventional hydraulic cylinder direct jacking mechanism of the prior art. The mobile-type composite jacking mechanism is characterized in that a hydraulic cylinder is mounted on a machine body, a piston rod is mounted in the hydraulic cylinder, a rolling chain wheel is mounted on the upper part of the piston rod through a pin roll, a chain is mounted on the rolling chain wheel, and one end of the chain is fixed on a lower chain seat at the bottom of the machine body through a pin roll while the other end is fixed on an upper chain seat at the lower part of the elevating sliding table. The beneficial effects of the mobile-type composite jacking mechanism are that the same elevating height can be achieved only by half of the cylinder stroke, thereby raising elevating speed and reducing cylinder costs; and meanwhile, the height of the elevating sliding table is reduced by one half correspondingly, thereby reducing the height of the elevating sliding table, i.e., reducing the weight of the elevating sliding table, lowering energy consumption during usage, and achieving the energy-saving aim.
Description
Technical field
The utility model belongs to auto hoist technical field, particularly for the compound lifting body of a kind of movable lifting machine for vehicles of movable lifting machine for vehicles.
Background technology
In vehicle maintenance and repair maintenance facility, movable lifting machine for vehicles has unique value of service because of its alerting ability.Current movable lifting machine for vehicles is hydraulic ram straight top type mechanism, and its oil cylinder stroke is consistent with lifting stroke, so oil cylinder stroke is long, lifting slide unit height is large, and the corresponding lifting time is longer, and complete machine weight is larger, cost is higher, and the energy consuming during use is also many.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art part, provide and only need half oil cylinder stroke can reach identical lift height, thereby improve lifting speed, reduce the weight of oil cylinder cost and lifting slide unit, reduce the catabiotic compound lifting body of a kind of movable lifting machine for vehicles for movable lifting machine for vehicles while using.
The technical solution adopted in the utility model comprises body, is arranged on the lifting slide unit on body, and hydraulic ram is also installed on body, and piston rod is installed in hydraulic ram, on piston rod top, by bearing pin, rolling chain wheel is installed, and chain is installed on rolling chain wheel.
One end of described chain is fixed on by bearing pin on the lower chain seat of organism bottom, and the other end is fixed in the upper chain stays of lifting slide unit bottom.
Compared with prior art, the beneficial effects of the utility model are, owing to adopting by hydraulic ram, piston rod, chain, rolling chain wheel and the lower chain seat and the compound lifting body that is fixed on the upper chain stays formation of lifting slide unit bottom that are fixed on organism bottom, during use, the utility model hydraulic ram is communicated with movable lifting machine for vehicles hydraulic power unit, under the effect of hydraulic power unit, only need the oil cylinder stroke of half can reach identical lift height, thereby improved lifting speed, reduce oil cylinder cost, simultaneously, lifting slide unit height also correspondingly subtracts and is a half, reduced the height of lifting slide unit, reduced the weight of lifting slide unit, the energy consuming when capable of reducing using, reached energy-conservation object.
The utility model can be controlled by the electric control system in the electric cabinet of movable lifting machine for vehicles, and by using single board computer (SBC) or PLC programming control, the movable lifting machine for vehicles of realizing two or many couplings in certain error limit is wired or wireless synchronous.

The specific embodiment
As shown in Figure 1, the utility model comprises body 1, be arranged on lifting slide unit 4 and hydraulic ram 7 on body 1, be arranged on the piston rod 6 in hydraulic ram 7, on piston rod 6 tops, by bearing pin, rolling chain wheel 2 is installed, chain 3 is installed on rolling chain wheel 2, and one end of described chain 3 is fixed on by bearing pin on the lower chain seat 8 of body 1 bottom, and the other end is fixed in the upper chain stays 5 of lifting slide unit 4 bottoms.
As shown in Figure 2, during use, the utility model hydraulic ram 7 is communicated with the hydraulic power unit 10 of movable lifting machine for vehicles, the rear portion of the body 1 of described movable lifting machine for vehicles is provided with storage battery 13 from top to bottom, electric unlocking mechanism 12 and hydraulic power unit 10 and traveling gear 9, rear casing 14 is arranged on outside, electric cabinet 11 is installed on rear casing, during work, first by electric lock mechanism 12 releases, hydraulic power unit 10 drives the piston rod 6 in hydraulic ram 7 to rise, owing to utilizing pulley principle, the rise height of piston rod 6 is half of original straight top type, and the stroke of lifting slide unit 4 is with originally identical, therefore, the rolling chain wheel 2 being fixed on piston rod 6 top bearing pins drives the chain 3 being fixed on lifting slide unit 4 to make lifting slide unit 4 increase with the double-speed of piston rod 6 risings simultaneously, arrive after operating altitude, catch gear 12 auto locks, guarantee safety.By the electric control system in electric cabinet 11, can make the movable lifting machine for vehicles of two or many couplings realize wired or wireless synchronous; During decline, electric unlocking mechanism 12 releases, hydraulic ram 7 releases, load and lifting slide unit 4 decline by deadweight, are fixed on the chain 3 in chain stays 5 on lifting slide unit 4 bottoms and roll on rolling chain wheel 2, and decline with lifting slide unit 4, until decline, put in place.
