Description
Technical field
The present invention relates to load-bearing jacking equipment technical field, be specifically related to the high load-bearing lifting table of a kind of practical conveyor line Gas fluid pressure integration.
Background technology
At present, the lifting table on market roughly has three kinds: Pneumatic elevation platform, hydraulic manual lifting table, automatically (electronic battery-type or internal combustion engine type) lifting table.But above three kinds have respective weakness respectively, economic, practical, quick, load-bearing, environmental protection cannot be embodied simultaneously, save time, labour-saving particular requirement.Although Pneumatic elevation platform source of the gas is convenient, speed is fast, load-bearing is limited, and general weight capacity is 100kg-150kg.Although the load-bearing of hydraulic manual lifting table energy, can not reach the height of specifying by fast lifting, general lifting velocity only has 5-10mm/s, and consume one's strength very much when raising, the words of high-mechanic will inevitably make rising or falling speed slow down, and trampling number of times increases, and muscle power increases simultaneously.
Although automatic rising-sinking platform energy is quick, the lifting of high-mechanic, it needs external power supply (storage battery) or adopts to use driving engine as power, also needs control system simultaneously.Involve great expense but also need external power supply, as conveyor line lifting table and inconvenience thereof, more cannot embody economy, environmental protection, practical requirement.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming prior art, a kind of quick load-bearing jacking system relating to pneumatic, hydraulic pressure, machinery three kinds of mechanics mechanisms is provided, especially without the need to when external power supply (storage battery) or oil-burning machine can fast lifting (10mm-15mm/S) again can the high load-bearing lifting table of a kind of Gas fluid pressure integration of high load-bearing (750kg-1000kg).
The high load-bearing lifting table of a kind of Gas fluid pressure integration of the present invention is achieved through the following technical solutions:
The high load-bearing lifting table of a kind of Gas fluid pressure integration, comprises vehicle frame, top plate, lower plywood, scissors fork trigger structure, oil cylinder, gas, hydraulic pressure integrated device, pedal device, relief arrangement, clearance fine adjustment device, positioning guide rail, handrail, cardan wheel belt brake, tight pulley, self-locking gas spring and baffle group, described vehicle frame is provided with positioning guide rail, positioning guide rail has clearance fine adjustment device; Scissors fork trigger structure comprises interior fork plate and outer fork plate; Top plate is connected with lower plywood by hinge, has a self-locking gas spring between top plate and lower plywood, and lower plywood is connected by rotating shaft with outer fork plate; Oil cylinder axle is connected with outer fork board support, and the other end is fixed in vehicle frame base; Gas, hydraulic pressure integrated device are screwed in vehicle frame base, and entrance point is gas source interface; Pedal device is connected on gas, hydraulic pressure integrated device switch by a connecting rod mechanism; Relief arrangement is connected on gas source switch.
As preferably, described interior fork plate one end is fixed on the bearing of lower plywood, and the other end is equipped with pulley, and the slide rail of lower plywood slides.
As preferably, described outer fork plate one end is fixed on the bearing of vehicle frame bottom, and the other end is movable is also provided with roller, and the slide rail of vehicle frame slides.
As preferably, described baffle group is movable part, is connected by plate-hanging type, is permanent seat vehicle frame being provided with fixed dam.
As preferably, described handrail is in vehicle frame both sides, and cardan wheel belt brake and tight pulley respectively have two, is positioned at vehicle frame bottom.
The turning activity of top plate, after the parts on top plate are finished, rises lower one deck, then overturns top plate to certain angle, support top plate, top plate is opened, conveniently takes off the parts of top plate by self-locking gas spring.Adopt self-locking type gas spring, make gas spring can not because of the reason of top plate self gravitation, permanent load-bearing in gas spring, and makes spring failure, causes top plate to drop, and causes potential safety hazard to occur.
By the motion of scissors fork trigger structure, make top plate and lower plywood realize a lifting up and down, vehicle frame is provided with positioning guide rail, work the friction and positioning action that reduce lifting; By the thrust that gas, hydraulic pressure integrated device produce, make the exhibition of oil cylinder shaft extension, make interior fork plate and the upper and lower mechanical movement of outer fork plate generation scissors, realize lifting, media is hydraulic oil, is connected by high pressure fuel pipe.
Gas, hydraulic pressure integrated device entrance point are gas source interface, external air source is connected by tracheae, quick coupling, reciprocal thrust is produced by pedal device, exit end is that hydraulic power exports, by the crank motion that entrance point produces, the built-in piston promoting this device produces the hydraulic thrust of high pressure by oil pipe to oil cylinder.
Pedal device, be connected on gas, hydraulic pressure integrated device switch by a connecting rod mechanism, when push down on the pedal, gas source switch is connected, and makes gas, the internal pump of hydraulic pressure integrated device produces the motion of reciprocal fast speed and promote piston.Relief arrangement is also be connected to gas source switch by lever principle, disconnects source of the gas when stepping on relief arrangement.
Clearance fine adjustment device is the uneven phenomenon in all around frame when upper and lower laminate produces when load-bearing is uneven and vehicle frame gap when occurring, can automatic regulating gap, in order to avoid laminate lifting occurs stuck up and down.This device is realized by spring automatic telescopic.
Baffle group baffle group is movable part, is permanent seat vehicle frame being provided with fixed dam, blocks parts on laminate not because of the unexpected and accident that drops, minimizing potential safety hazard when object is and laminate is elevated, not the used time desirable under.
Compared with prior art, the beneficial effect of the high load-bearing lifting table of a kind of Gas fluid pressure integration of the present invention is: additionally need not increase equipment or resource (as electri forklift or fuel oil type fork truck), the source of the gas making full use of workshop cheapness abundant substitutes manpower, reduce the labour intensity of factory assembling line operator, can rise on required parts to conveyor line platform for assembling by fast lifting again simultaneously.
