Abstract
The invention provides a pneumatic balance system for a cylinder. The system comprises a cylinder with a piston rod vertically downwards arranged, and a brake arranged corresponding to the piston rod of the cylinder. The system further comprises a first gas supply pipeline communicating with a rod cavity of the cylinder, and a second gas supply pipeline communicating with the brake; the first gas supply pipeline is provided with a pressure reducing valve and an exhaust valve, wherein the exhaust valve is arranged between the pressure reducing valve and the cylinder; and the second gas supply pipeline is provided with a normally-closed two-position three-way valve. In the pneumatic balance system for the cylinder, through control of the system, when a detecting platform works, the pressure of the rod cavity in the cylinder is balanced to always counteract self gravity of the detecting platform. If such special conditions as gas breakage and power failure suddenly occur, the brake can quickly lock a cylinder rod, so that a ball screw cannot be damaged in working of the detecting platform, the lifting precision control of the detecting platform is improved, and the accuracy of detecting results is guaranteed.
Description
Technical field
The invention belongs to steel tube supersonic Detection Techniques field, more particularly, to a kind of cylinder air-balance system
System.
Background technology
Production technology of steel tube both domestic and external relate to the application of pneumatic principle at present.But due to detection platform self gravitation compared with
Conference causes ball-screw serious wear, reduces leading screw its service life, thus how to design a detection platform balance system into
For new research and development problem.
The content of the invention
In view of this, the invention is directed to a kind of cylinder pneumatic counterbalance system, with the control to detection platform
System, thus reduces the abrasion of ball-screw.
To reach above-mentioned purpose, what the technical scheme of the invention was realized in：
A kind of cylinder pneumatic counterbalance system, including the cylinder that arranges straight down of a piston rod and with the cylinder piston rod
The brake being correspondingly arranged, the second supply for also including the first supply air line connected with cylinder rod chamber and connecting with brake
Pipeline, first supply air line are provided with air relief valve and air bleeding valve, and wherein air bleeding valve is arranged between air relief valve and cylinder, and described
Two supply air lines are provided with a normally closed type two position three-way valve.
Further, the air bleeding valve is provided with deafener.
Further, the cylinder rodless cavity gas outlet is connected with deafener.
Relative to prior art, a kind of cylinder described in the invention is had the advantage that with pneumatic counterbalance system：
A kind of cylinder pneumatic counterbalance system described in the invention, by the system control, when detection platform works
When, in balance cylinder, the pressure of rod chamber can offset detection platform self gravitation all the time.Such as run into die suddenly, power-off etc. it is special
Situation, brake can pin rapidly cylinder rod.Ensure that detection platform will not cause to damage to ball-screw when working, improve
Detection platform lifts the control of precision, also so as to ensure that the accuracy of testing result.

Below with reference to the accompanying drawings and in conjunction with the embodiments describing the invention in detail.
As shown in figure 1, a kind of cylinder pneumatic counterbalance system, including the cylinder 6 that arranges straight down of a piston rod and with
The brake 7 that 6 piston rod of cylinder is correspondingly arranged, also include the first supply air line for connecting with 6 rod chamber of cylinder and with braking
Second supply air line of the connection of device 7, first supply air line are provided with air relief valve 1 and air bleeding valve 2, and the air bleeding valve 2 is provided with
Deafener 3, wherein air bleeding valve 2 are arranged between air relief valve 1 and cylinder 6, and second supply air line is provided with a normally closed type two three
Port valve 5, the pneumatic member on pneumatic member, the second supply air line on the first supply air line are formed by connecting into by pipeline 4 respectively.
In the present embodiment, the cylinder rodless cavity gas outlet is connected with deafener.
The present embodiment specific work process is：Detection platform is arranged on cylinder piston rod bottom, the first supply air line and
All in aeration status all the time, thus detection platform is imposed active force upwards, therefore detection platform by cylinder to two supply air lines
The pressure of leading screw is reduced, therefore reduces the infringement to leading screw, extend the service life of leading screw.When normally closed type two-position three way
During 5 power-off of valve, 5 gas circuit of normally closed type two position three-way valve disconnects, and cylinder piston rod is at once held in brake tightly, prevent cylinder piston rod after
Continuous to move down, the same gravity for ensureing detection platform itself is not all acted on leading screw, therefore reduces the infringement to leading screw.
The preferred embodiment of the invention is the foregoing is only, it is not to limit the invention, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
