Abstract
The invention discloses a lifting rack of a target loading and unloading trolley. The lifting rack comprises a pedal, a manual pump, a hydraulic cylinder, chain wheels, a lifting frame and a return valve control handle, wherein two chain wheels are fixedly mounted on two sides of the top end of the hydraulic cylinder and connected with the lifting frame through chains; the manual pump and an oil tank are arranged at the bottom end of the hydraulic cylinder, an oil discharge one-way valve is arranged between the manual pump and the hydraulic cylinder, a return valve and a pressure maintaining valve are arranged between the oil tank and the hydraulic cylinder, and an oil suction one-way valve is arranged between the manual pump and the oil tank; the pedal is arranged above the manual pump, and a compressed spring is arranged between the pedal and the manual pump; the return valve control handle is connected to the lower end of the hydraulic cylinder. The lifting rack can be used as a lifting device for the target loading and unloading trolley, so that a target is conveniently and rapidly replaced, the labor intensity of a worker is greatly reduced, and the production efficiency is improved. The lifting rack is mainly applied to replacement and maintenance of rotary targets of vertical coating equipment.
Description
Technical field
The present invention relates to a kind of jacking system, specifically a kind of target handling dolly elevator platform.
Background technology
In ITO plated film is produced, very strict to environmental requirement, owing to restricting by factory site, general uneasiness dress lifting appliance, and in ITO plated film is produced, often must change target according to need of production, target is aggregated in more than 80 kilograms together with the magnetic axle installed in its material, installation site is very inconvenient handling again, and the replacing of target is very thorny.
Summary of the invention
A kind of target is the object of the present invention is to provide to load and unload dolly elevator platform, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of target handling dolly elevator platform, comprises foot-operated, manual pump, hydraulic actuating cylinder, sprocket wheel, crane and reflux valve control handle; Described sprocket wheel is two and is fixedly installed in both sides, hydraulic actuating cylinder top; Sprocket wheel connects crane by chain.Hydraulic actuating cylinder bottom is provided with manual pump and fuel tank, is provided with foot-operated above described manual pump, is provided with stage clip between pedal manual pump.Hydraulic actuating cylinder lower end is connected with reflux valve control handle.
As the further scheme of the present invention: be provided with oil extraction check valve between described manual pump and hydraulic actuating cylinder, be provided with reflux valve and pressure retaining valve between fuel tank and hydraulic actuating cylinder, between manual pump and fuel tank, be provided with oil sucting one-way valve.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can load and unload the jacking system of dolly as target, make to change target and become convenient and swift, greatly reduce the labour intensity of workman, improve production efficiency.The present invention is mainly used in replacing and the maintenance of the rotary target material of vertical filming equipment.

Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
Refer to Fig. 1-2, a kind of target handling dolly elevator platform, comprise foot-operated 1, manual pump 3, hydraulic actuating cylinder 5, sprocket wheel 6, crane 8 and reflux valve control handle 9; Described sprocket wheel 6 is two and is fixedly installed in both sides, hydraulic actuating cylinder 5 top; Sprocket wheel 6 connects crane 8 by chain 7.Hydraulic actuating cylinder 5 bottom is provided with manual pump 3 and fuel tank 4, is provided with oil extraction check valve 11 between manual pump 3 and hydraulic actuating cylinder 5, is provided with reflux valve 13 and pressure retaining valve 12, is provided with oil sucting one-way valve 10 between manual pump 3 and fuel tank 4 between fuel tank 4 and hydraulic actuating cylinder 5.Be provided with foot-operated 1 above described manual pump 3, between foot-operated 1 manual pump 3, be provided with stage clip 2.Hydraulic actuating cylinder 5 lower end is connected with reflux valve control handle 9.
Principle of work of the present invention is:
In use, step on foot-operated 1, the hydraulic oil in pump is pressed in hydraulic actuating cylinder 5 by oil extraction check valve 11 by manual pump 3, makes the piston in hydraulic actuating cylinder 5 increase, and is pulled upwardly by crane 8 by sprocket wheel 6 and chain 7; Unclamp foot-operated 1, stage clip 2 makes foot-operated 1 to reset, and the hydraulic oil in fuel tank 4 is entered in manual pump 3 by oil sucting one-way valve 10.So constantly stepping on foot-operated 1 makes crane 8 be pulled up.
Move reflux valve control handle 9, the hydraulic oil in hydraulic actuating cylinder 5 flows back to fuel tank 4 by reflux valve 13; Piston in hydraulic actuating cylinder 5 declines, and crane 8 gravitate moves downward.Unclamp reflux valve control handle 9, crane 8 stops; Constantly move reflux valve control handle 9, crane 8 constantly declines.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
