Abstract

The invention discloses an electrical-hydraulic control device of an anti-falling constraining device. The electrical-hydraulic control device comprises a pump source module, an oil path control module, an energy accumulator module and a motor module, the pump source module comprises a hydraulic pump, a motor, a first overflow valve and a first stop valve, the oil path control module comprises a check valve, a first electromagnetic directional valve, a second electromagnetic directional valve, a third electromagnetic directional valve, a second overflow valve, a safety valve, a first pressure relay and a second pressure relay, the energy accumulator module comprises an energy accumulator, a second stop valve, a third stop valve, a third overflow valve and a fourth electromagnetic directional valve, and the motor module comprises a motor and a constraining belt fixing device. The electrical-hydraulic control device is high in automation degree and can be remotely controlled, the output torque can be precisely adjusted, the adjusting range is large, an object is constrained, and meanwhile the object cannot be damaged. The electrical-hydraulic control mode can be adopted, the hydraulic drive control mode can also be adopted, and the different requirements of a user for working with the high automation degree or under the low-cost and bad working condition can be met.

Description

technical field [0001] The invention relates to a control device, in particular to an electro-hydraulic control device of an anti-escape restraint device. Background technique [0002] In the field of restraint for mental patients, criminals, and goods with anti-damage requirements, the existing restraint devices are all manually operated, relying on rigid locking or flexible locking of mechanical structures, such as binding restrained objects with restraint belts. The size of the restraint force of this type of restraint device 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. Tight and lead to poor blood circulation in the local skin, resulting in damage. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a control device for an electromechanical-hydraulic integrated restraint device with adjustable ...
