Multi-group multi-way valve combined control system and driving and anchoring machine

Abstract

The invention discloses a multi-group multi-way valve combined control system. The multi-group multi-way valve combined control system comprises N groups of electric proportional multi-way valves, hydraulic driving devices and a control device, wherein the control device is electrically connected with the electric proportional multi-way valves respectively; the electric proportional multi-way valves are connected with the corresponding hydraulic driving devices respectively, and are used for receiving control signals output by the control device and correspondingly controlling the hydraulic driving devices to act according to the control signals; and N is a positive integer greater than 2. By applying the multi-group multi-way valve combined control system provided by the invention, the multi-group multi-way valves are controlled in a combined way, so that use of a plurality of control boxes is avoided. One person can control the multi-group multi-way valves simultaneously through themulti-group multi-way valve combined control system, so that the number of personnel is reduced. An operator can operate through the control device in a visual field range, and does not need to stay beside each operating valve to finish operation, so that the operator operates the system simply, flexibly and safely. The invention further discloses a driving and anchoring machine which also has thetechnical effects.

Description

technical field [0001] The invention relates to the technical field of coal mine construction, and more specifically relates to a multi-group multi-way valve joint control system and a bolter. Background technique [0002] At present, in the process of coal mine roadway construction, coal mine equipment requires one machine with multiple functions, such as bolter miners, which are required to complete functions such as tunneling and anchor protection. The existing equipment is driven by a hydraulic system. Both the hydraulic cylinder and the hydraulic motor are controlled by multi-way valves. For example, one group of multi-way valves controls the movement of walking and outriggers, and the other group of multi-way valves controls the movement of a drill arm. There is a group of multi-way valves that control the arm movement of the equipment; according to the number of these working mechanisms, multiple sets of multi-way valves are required, and most of these multi-way valve...
