Abstract
The utility model discloses a scissor fork type hydraulic elevator, which comprises a base, a hydraulic mechanism, a scissor fork mechanism, a loading platform and an air cylinder jacking device, wherein the lower part of the scissor fork mechanism is movably connected with the base, the upper part of the scissor fork mechanism is movably connected with the loading platform, the lower part of the hydraulic mechanism is movably connected with the base, the upper part of the hydraulic mechanism is movably connected with the upper part of the scissor fork mechanism, and the air cylinder jacking device is also fixedly arranged on the base. When the hydraulic elevator starts to be used for lifting, the air cylinder jacking device is firstly started, a device platform is jacked to a certain height, then, the hydraulic mechanism is started for continuous jacking, the original jacking work at the initial stage of the hydraulic mechanism is completed by the air cylinder jacking device, the action force of a hydraulic oil cylinder of the hydraulic mechanism on a rotation joint and a connecting rod of the scissor fork mechanism at the initial lifting stage of the elevator is reduced, the mechanism abrasion is greatly reduced, the equipment failure is reduced, meanwhile, the efficiency is improved, the structure is simple, and the operation is convenient.
Description
Technical field
The utility model relates to the elevator technology field, refers to especially a kind of fork hydraulic elevator.
Background technology
A kind of lifter apparatus that hydraulic hoist is comprised of traveling gear, hydraulic gear, electric control mechanism, supporting mechanism.Hydraulic oil forms certain pressure by blade-type pump, enters the fluid cylinder lower end through oil filter, flame-proof type solenoid directional control valve, flow regulating valve, hydraulic control one-way valve, balance cock, makes the piston upward movement of fluid cylinder, lifting heavy.Existing hydraulic hoist mainly contains several structures of scissor-type, crank arm type, double-cylinder type and aluminum alloy type; Lifting altitude does not wait from 4 meters to 38 meters.The fork hydraulic elevator is because it has the fork of cutting physical construction, makes the bay-lift higher stability that hoists, and roomy job platform and higher load-carrying capacity are widely used in a plurality of fields such as factory floor open air.Existing fork hydraulic elevator is when beginning to promote, because the expansion link of hydraulic gear is in heeling condition, so its power thrusts also is the inclination upward direction, supposes that it firmly is F, the angle of itself and vertical direction is α, the component F1=Fcos α of its in the vertical direction, along with the lifting of height, angle α reduces gradually, F1 increases gradually, be also that the strength waste is fewer, that is to say that hydraulic hoist is more in its strength waste of lifting initial stage, plays the strength waste in the lifting later stage less.Therefore, minimizing strength waste, raising hydraulic compressor work efficiency have just become the elevator structure to improve upward problem demanding prompt solution.In addition, hydraulic hoist makes its mechanism wear large at the lifting initial stage to the application force of scissors mechanism connecting rod and rotary joint, and equipment failure rate is high.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic hoist that the cylinder jacking apparatus is installed that increases, and reduces the waste of hydraulic compressor strength, reduces simultaneously scissors mechanism connecting rod and rotary joint mechanism wear, raises the efficiency.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of fork hydraulic elevator has comprised pedestal, hydraulic gear, scissors mechanism, loading platform and cylinder jacking apparatus, and scissors mechanism bottom and pedestal are flexibly connected, and top and loading platform are flexibly connected; Hydraulic gear bottom and pedestal are flexibly connected, and top is connected with the scissors mechanism top movable; It is characterized in that: also be installed with the cylinder jacking apparatus on described pedestal.
Compared with prior art, the utility model is after pedestal installs the cylinder jacking apparatus additional, when hydraulic hoist begins to promote, first start the cylinder jacking apparatus with the apparatus platform jacking to certain altitude, restart hydraulic gear and begin to continue jacking, the lifting work at former initial stage of hydraulic gear is turned by the cylinder jacking apparatus complete, reduced the strength waste of hydraulic gear, reduce simultaneously scissors mechanism connecting rod and rotary joint mechanism wear, simple in structure, easy to operate.
Description of drawings
Fig. 1 is the constructional drawing of the utility model embodiment.
Label in figure is: 1, pedestal; 2, hydraulic gear; 3, scissors mechanism; 4, loading platform; 5, cylinder jacking apparatus.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the utility model embodiment has comprised pedestal 1, hydraulic gear 2, scissors mechanism 3, loading platform 4 and cylinder jacking apparatus 5, and scissors mechanism 3 bottoms and pedestal 1 are flexibly connected, and top and loading platform 4 are flexibly connected; Hydraulic gear 2 bottoms and pedestal 1 are flexibly connected, and top is connected with scissors mechanism 3 top movable; Pedestal 1 on also be installed with cylinder jacking apparatus 5.After pedestal 1 installs cylinder jacking apparatus 5 additional, when hydraulic hoist begins to promote, first start cylinder jacking apparatus 5 with apparatus platform 4 jackings to certain altitude, restart hydraulic gear 2 and begin to continue jacking, the lifting work at 2 former initial stages of hydraulic gear is turned by cylinder jacking apparatus 5 complete, reduce the strength waste of hydraulic gear 2, improved simultaneously efficient, simple in structure, easy to operate.
Above demonstration and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
