Embodiment 1

[0050] Embodiment 1: When using electromagnetic control mode to work:

[0051] like figure 2 As shown, the air source module includes an air pressure generating device 1 and a first shut-off valve 2;

[0052] like figure 2 As shown, the loop control module includes a check valve 3, a first pressure relay 4, a second electromagnetic reversing valve 9, a second pressure relay 10, a second overflow valve 12 and a third electromagnetic reversing valve 13, The one-way valve 3 is connected to the oil inlet of the motor 11 in the motor output module through the second electromagnetic reversing valve 9, and the oil outlet of the motor 11 is connected to the outside atmosphere through the second overflow valve 12 and the third electromagnetic reversing valve 13. The first pressure relay 4 is connected between the one-way valve 3 and the second electromagnetic reversing valve 9, and the second pressure relay 10 is connected between the second electromagnetic reversing valve 9 and th...

Embodiment 2

[0059] Embodiment two; when adopting manual control mode to work:

[0060] Replace the electromagnetic reversing valve with a manual reversing valve, replace the pressure relay with a pressure gauge, and complete the system control requirements through manual observation of the pressure gauge, which reduces the degree of automation and control accuracy of the system, but improves the system's adaptability to the field environment, etc. The ability of harsh working conditions, while reducing the cost of equipment.

[0061] like image 3 As shown, the air source module includes an air pressure generating device 21 and a first shut-off valve 22;

[0062] like image 3 As shown, the loop control module includes a check valve 23, a first pressure gauge 24, a first manual reversing valve 28, a second pressure gauge 29, a second relief valve 31 and a second manual reversing valve 32, The one-way valve 23 is connected to the oil inlet of the motor 30 in the motor output module thro...

Abstract

The invention relates to a pneumatic control device of a restraint device. The pneumatic control device comprises an air source module, a loop control module, an energy accumulator module and a motor output module, wherein the air source module comprises an air pressure generation device and a first stop valve; the loop control module comprises a one-way valve, a first pressure relay, a second electromagnetic reversing valve, a second pressure relay, a second overflow valve and a third electromagnetic reversing valve; the energy accumulator module comprises an energy accumulator, a first overflow valve, a second stop valve and a first electromagnetic reversing valve; the motor output module comprises a motor, and the motor is coaxially connected with the restraint device. According to the pneumatic control device disclosed by the invention, high-pressure gas is supplied by the energy accumulator, the pressure pulsation of the air pressure generation device is reduced, the noise is reduced, and a system works stably; the energy accumulator and the motor work simultaneously, thus the control accuracy is high, the transmission efficiency is high, the transmission reliability is high, the structure is simple, and the operation is convenient; the pneumatic control device not only can adopt an electromagnetic control mode, but also can adopt a manual control mode.

Description

technical field [0001] The invention belongs to the field of electric-pneumatic integrated power transmission control devices, and in particular relates to a pneumatic control device of a restraint device. Background technique [0002] Most of the existing restraint devices are manually operated, relying on the rigid or flexible locking of the mechanical structure, such as directly binding the mentally ill with ropes. The disadvantages of this type of device are: the size of the restraining force is not easy to control, the reliability is not high, it consumes manpower, and it is easy to cause physical damage to the restrained object, such as strangling the human skin, resulting in abnormal blood circulation. Contents of the invention [0003] The present invention overcomes the shortcomings in the prior art, and provides a pneumatic control device for a restraint device, which is an electrical integrated control device that is supplied with pressure by an accumulator and ...
