Description
Technical field
The invention belongs to mechanical engineering technical field, more particularly to a kind of flexibility thousand based on pneumatics
Jin top.
Background technology
In logistics, storage, squeezing processing industry, jack is using relatively broad.At present, jack with
Hydraulic pressure and it is mechanical based on.Itself total amount of these jack is big, and jacking weight is larger, not portable,
It should not be used in logistics, the jacking and carrying of storage sector light matter body.Moreover, hydraulic pressure or mechanical very heavy
It is very useful when the squeezing process of food processing, the problems such as due to mechanical clearance and hydraulic packing, be easily caused
The problems such as extruding bounce-back.
The content of the invention
The present invention provides a kind of based on the soft of pneumatics to solve technical problem present in known technology
Property jack.
It is easy to use it is an object of the invention to provide a kind of design science, working stability, lasting pressurize,
Carrying portable, environmental protection can be widely applied to weight jacking, squeeze the jack in field.
Flexible jack of the invention based on pneumatics is adopted the technical scheme that：
A kind of flexible jack based on pneumatics, is characterized in：It is flexible very heavy based on pneumatics
Top includes jacking cylinder, foot-operated cylinder, pedal and connecting line；Pedal is stepped on, cylinder is ridden by air
Jacking cylinder is filled with, driving jacking cylinder rises；Pedal is unclamped, foot-operated cylinder resets and sucks air；
Jacking cylinder is vented, and realizes that weight is put down or jacking cylinder resets.
Flexible jack of the invention based on pneumatics can also be adopted the following technical scheme that：
The described flexible jack based on pneumatics, is characterized in：Foot-operated cylinder is stretched for spring reset
Go out type single-acting cylinder, equipped with an inlet channel and an exhaust passage.
The described flexible jack based on pneumatics, is characterized in：Jacking cylinder contracts for spring reset
Hollow single-acting cylinder, equipped with an inlet channel and two exhaust passages, two exhaust passages are respectively
Exhaust passage and Quick air-discharge passage at a slow speed.
The described flexible jack based on pneumatics, is characterized in：Foot-operated cylinder intake passage is according to gas
Stream direction is sequentially arranged with filter, foot-operated cylinder check valve.
The described flexible jack based on pneumatics, is characterized in：Jacking cylinder inlet channel is according to gas
Flow direction and jacking cylinder check valve is housed, and communicated with foot-operated cylinder exhaust passage.
The described flexible jack based on pneumatics, is characterized in：Exhaust passage is according to air-flow side at a slow speed
To being sequentially arranged with stop valve, choke valve, muffler at a slow speed.
The described flexible jack based on pneumatics, is characterized in：Quick air-discharge passage is according to air-flow side
To being sequentially arranged with rapid closing stop valve, muffler.
The present invention has the advantages and positive effects of：
Flexible jack based on pneumatics is and existing as a result of the brand-new technical scheme of the present invention
Technology is compared, and the present invention uses air as driving medium, strong adaptability, environmental protection；Air can
Compressibility, operating pressure is small by leakage contribution, pressure stability；Aeroelastic preferably, is squeezed without bounce-back,
Jack has preferable flexible；Pneumatic means, it is lightweight, it is easy to carry.The purpose of the present invention is to carry
It is easy to use for a kind of design science, working stability, lasting pressurize, carrying portable, environmental protection,
It can be widely applied to weight jacking, squeeze the jack in field.

Embodiment
In order to further understand the content, features and effects of the present invention, following examples are hereby enumerated,
And it is as follows to coordinate accompanying drawing to describe in detail：
Refering to accompanying drawing 1.
Embodiment 1
A kind of flexible jack based on pneumatics includes jacking cylinder, foot-operated cylinder, pedal and connection
Pipeline；Pedal is stepped on, foot-operated cylinder inflates air to jacking cylinder, and driving jacking cylinder rises；Unclamp
Pedal, foot-operated cylinder resets and sucks air；Jacking cylinder is vented, and realizes that weight is put down or jacking cylinder
Reset.
Foot-operated cylinder is spring reset stretching type single-acting cylinder, is vented equipped with an inlet channel and one
Passage.Jacking cylinder is spring reset retraction type single-acting cylinder, is arranged equipped with an inlet channel and two
Gas passage, two exhaust passages are exhaust passage and Quick air-discharge passage at a slow speed respectively.Foot-operated cylinder intake
Passage is sequentially arranged with filter, foot-operated cylinder check valve according to airflow direction.Jacking cylinder inlet channel is according to gas
Flow direction and jacking cylinder check valve is housed, and communicated with foot-operated cylinder exhaust passage.At a slow speed exhaust passage according to
Airflow direction is sequentially arranged with stop valve, choke valve, muffler at a slow speed.Quick air-discharge passage is according to airflow direction
It is sequentially arranged with rapid closing stop valve, muffler.
The specific implementation process of the present embodiment：
Rapid closing stop valve is opened, jacking cylinder is vented through rapid closing stop valve, muffler, and jacking cylinder resets.
Jacking cylinder is steadily positioned over and below jacking weight, is closed rapid closing stop valve and at a slow speed stop valve.With
The reciprocal pushes pedals of pin.Pedal is lifted, outside air sucks foot-operated through filter, foot-operated cylinder check valve
Cylinder；Pedal is stepped on, air is filled with the jacking that jacking cylinder realizes weight through jacking cylinder check valve.Open
Stop valve at a slow speed is opened, jacking cylinder is vented through stop valve at a slow speed, choke valve and muffler, can put down weight
Surely put down.
