Description

A kind of gas-liquid is pressed integrated high load-bearing lifting table

Technical field

The present invention relates to load-bearing jacking equipment technical field, be specifically related to a kind of practical conveyor line and press integrated high load-bearing lifting table with gas-liquid.

Background technology

At present, the lifting table on the market roughly has three kinds: Pneumatic elevation platform, hydraulic manual lifting table, automatic (electronic battery-type or internal combustion engine type) lifting table.But above three kinds of weakness that have respectively separately can't embody simultaneously economic, practical, quick, load-bearing, environmental protection, save time, the 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 hydraulic manual lifting table can load-bearing, can not fast lifting reach the height of appointment, generally 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 the 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 simultaneously control system.Involve great expense but also the need external power supply, with lifting table and inconvenience thereof, more can't embody the requirement of economy, environmental protection, practicality as conveyor line.

Summary of the invention

The object of the invention is to overcome the shortcoming and defect of prior art, a kind of quick load-bearing jacking system that relates to pneumatic, hydraulic pressure, three kinds of mechanics mechanisms of machinery is provided, especially need not in the situation of external power supply (storage battery) or oil-burning machine can fast lifting (10mm-15mm/S) again can high load-bearing (750kg-1000kg) a kind of gas-liquid press integrated high load-bearing lifting table.

A kind of gas-liquid of the present invention presses integrated high load-bearing lifting table to be achieved through the following technical solutions:

A kind of gas-liquid is pressed integrated high load-bearing lifting table, comprises vehicle frame, top plate, lower plywood, scissors fork plate mechanism, oil cylinder, gas, hydraulic pressure integrated device, pedal device, relief arrangement, the clearance fine adjustment device, positioning guide rail, handrail, the cardan wheel belt brake, tight pulley, self-locking gas spring and baffle group, at described vehicle frame positioning guide rail is installed, gapped micromatic setting on the positioning guide rail; Scissors fork plate mechanism comprises interior fork plate and outer fork plate; Top plate is connected with lower plywood by hinge, and a self-locking gas spring is arranged between top plate and the lower plywood, and lower plywood is connected by rotating shaft with outer fork plate; The oil cylinder axle is connected with outer fork board support, and the other end is fixed on the vehicle frame base; Gas, hydraulic pressure integrated device are screwed on the vehicle frame base, and entrance point is gas source interface; The pedal device is connected on gas, the hydraulic pressure integrated device switch by a connecting rod mechanism; Relief arrangement is connected on the 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, slides at the slide rail of lower plywood.

As preferably, described outer fork plate one end is fixed on the bearing of vehicle frame bottom, and the movable roller that also is equipped with of the other end slides at the slide rail of vehicle frame.

As preferably, described baffle group is movable part, connect by plate-hanging type, and be the permanent seat that fixed dam is installed on the vehicle frame.

As preferably, described handrail is in the vehicle frame both sides, and cardan wheel belt brake and tight pulley respectively have two, are positioned at the vehicle frame bottom.

The turning activity of top plate after the parts on the top plate are finished, is risen lower one deck, and the top plate that then overturns supports top plate to certain angle by the self-locking gas spring, and top plate is opened, and conveniently takes off the parts of top plate.Adopt the self-locking type gas spring, make the gas spring can be because of the reason of top plate self gravitation, permanent load-bearing be in gas spring, and makes spring failure, causes that top plate drops, and causes potential safety hazard to occur.

Motion by scissors fork plate mechanism makes top plate and lower plywood realize up and down a lifting, at vehicle frame positioning guide rail is installed, and works the friction and the positioning action that reduce lifting; Thrust by gas, hydraulic pressure integrated device produce makes the exhibition of oil cylinder shaft extension, makes the up and down mechanical movement of interior fork plate and outer fork plate generation scissors, realizes lifting, and media is hydraulic oil, connects by high pressure fuel pipe.

Gas, hydraulic pressure integrated device entrance point are gas source interface, connect external air source by tracheae, quick coupling, produce reciprocal thrust by the pedal device, exit end is hydraulic power output, by the crank motion that entrance point produces, the hydraulic thrust that the built-in piston that promotes this device produces high pressure by oil pipe to oil cylinder.

The pedal device, be connected on gas, the hydraulic pressure integrated device switch by a connecting rod mechanism, when push down on the pedal, gas source switch is connected, and makes the internal pump of gas, hydraulic pressure integrated device produce reciprocal fast speed and moves pushing piston.Relief arrangement also is to be connected to gas source switch by lever principle, disconnects source of the gas when stepping on relief arrangement.

The clearance fine adjustment device is when to be all around frame that produces when load-bearing is inhomogeneous when laminate up and down with the inhomogeneous phenomenon in vehicle frame gap occur, and the energy capable of automatic regulating gap is in order to avoid laminate lifting generation is stuck up and down.This device is realized by the spring automatic telescopic.

The baffle group baffle group is movable part, is the permanent seat that fixed dam is installed on the vehicle frame, and purpose is to block parts on the laminate when making the laminate lifting not because of the unexpected accident that drops, and reduces potential safety hazard, desirable time of time spent.

Compared with prior art, a kind of gas-liquid of the present invention presses the beneficial effect of integrated high load-bearing lifting table to be: need not additionally increase equipment or resource (such as electri forklift or fuel oil type fork truck), take full advantage of the cheap abundant source of the gas in workshop and substitute manpower, reduce the assembling line operator's of factory labour intensity, simultaneously again can fast lifting play required parts and to the conveyor line platform, be used for assembling.
