Description

A kind of shearing type lifter starting boosting mechanism
Technical field
The invention belongs to lifting machine field, more particularly, relate to a kind of shearing type lifter starting boosting mechanism.
Background technology
The basic functional principle of shearing type lifter is as follows: drive cylinder piston rod by hydraulic ram, and liquid presses piston pole drives
Be arranged on the push and pull system between top board and base plate, push and pull system is stretched, and drives top board to realize being elevated abreast.Linkwork turnkey
Draw together one group of bar, such as upper ejector pin, upper moveable rod, lower fixed rod, lower lever etc., these bars also can be referred to as " interior tool arm ".Shearing type lifter is compared with vertical lifting machine, and structure is simpler, lightweight, operation is dexterous, height that is complete machine is little.
But shearing type lifter is existing defects also, the cylinder piston rod of existing shearing type lifter is connected directly between on interior tool arm.In the starting stage of lifting, and when being in lowest order, the angle changing rate that hoists that cylinder piston rod and interior tool arm are formed is little, and the degree of utilization for oil cylinder power output is lower.After progressively hoisting, along with the increase of the angle that hoists, the degree of utilization of oil cylinder power output improves.For traditional shearing type lifter, if wish to obtain good hoisting force in the starting stage, just need to use high-performance oil cylinder, but the power of this oil cylinder has a lot of leaving unused in the lifting middle and later periods, degree of utilization is not high, causes unnecessary waste, makes the manufacturing cost of shearing type lifter increase yet.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the invention provides manufacturing cost and complete machine weight that a kind of shearing type lifter starting boosting mechanism can reduce shearing type lifter, reduce the power requirement to oil cylinder, the power solving oil cylinder has a lot of leaving unused in the lifting middle and later periods, degree of utilization is not high, causes the problem of unnecessary waste.
2, technical scheme
In order to solve the problem, the technical solution adopted in the present invention is as follows:
A kind of shearing type lifter starting boosting mechanism, comprise top board, the arm of force in first, the arm of force in second, base plate, boosting-rod cylinder piston rod and roller, the front end of described boosting-rod, middle part and rear end respectively correspondence be provided with the second articulated bracket, first articulated bracket and the 3rd articulated bracket, described first articulated bracket is flexibly connected with the arm of force in the arm of force in first and second respectively, described second articulated bracket is flexibly connected with cylinder piston rod, described 3rd articulated bracket is hinged to described roller S. A., in described first, the two ends of the arm of force are hinged with the diagonal angle end of top board and base plate respectively, in described second, the two ends of the arm of force are hinged with another diagonal angle end of top board and base plate respectively, described boosting-rod is triangular structure, and the angle of described first articulated bracket place hinge hole and described second articulated bracket and the 3rd articulated bracket place hinge hole is 90 ° ~ 150 °, described first articulated bracket place hinge hole is equal with the distance of described 3rd articulated bracket place hinge hole with described first articulated bracket place hinge hole with the distance of described second articulated bracket.
Further, the base plate of described shearing type lifter is provided with track, described roller rolls in orbit.
Further, the distance of described first articulated bracket place hinge hole and described second articulated bracket can also be greater than the distance of described first articulated bracket place hinge hole and described 3rd articulated bracket place hinge hole.
Further, described boosting-rod is provided with from described second articulated bracket and described cylinder piston rod active connection place the chute matched with described cylinder piston rod size in the middle part of described boosting-rod lower surface.
3, beneficial effect
Compared to prior art, beneficial effect of the present invention is:
(1) the starting boosting mechanism of shearing type lifter of the present invention utilizes boosting-rod to increase to be lifted at the lifting starting stage for the Occupation coefficient of oil cylinder horsepower output, thus increase initial hoisting force, thus the power requirement of shearing type lifter for oil cylinder can be reduced, reduce the manufacturing cost of shearing type lifter.
(2) the present invention is greater than the distance of the first articulated bracket in the middle part of weighing arm and boosting-rod to roller due to the arm of force of boosting-rod and the whole length of boosting-rod, and before lifting starts, the roller end of boosting-rod contacts the fulcrum of a formation movement with lifter bottom plate, and because the angle of the first articulated bracket place hinge hole and described second articulated bracket and the 3rd articulated bracket place hinge hole is 90 ° ~ 150 °, make just there is the angle that hoists at cylinder piston rod when starting to walk, be unlikely to directly to hoist from horizon, thus the power requirement greatly reduced oil cylinder, reduce complete machine weight and cost, the power solving oil cylinder has a lot of leaving unused in the lifting middle and later periods, degree of utilization is not high, cause the problem of unnecessary waste,
(3) the present invention can use less oil pressure, reduces the wearing and tearing of hydraulic efficiency pressure system, improves its service life;
(4) the present invention also has the advantage that structure is simple, reasonable in design, be easy to manufacture.
