摘要： A system for navigation detection and inclination measurement of advanced hydraulic supports, including a detection device module, a signal transfer transmission module, connected to the detection device module, and used to integrate ultrasonic signals and inclination signals received from all advanced hydraulic supports and then wirelessly transmit all the signals to an analysis and processing module. The analysis and processing module, connected to the signal transfer transmission module, and used to receive the signals from the signal integration and transmission device for analysis, where if an analysis result shows an abnormal situation, an alarm will b e immediately given to a worker. If the analysis result shows a continuous abnormal situation, or a relatively large value indicating the abnormal situation is generated, a command will be immediately sent to make the advanced hydraulic supports stop operating in a current mode.

摘要： A method of treating tunnel collapse includes mounting a shield plate, a column, a support column to form a combined support and moving the combined support onto an operation platform, lifting up the combined support, and enabling the height of canopy to be greater than the height of an initial supporting arch. Actively contacting a surface of a collapse cavity by a fixed support column and bearing a load, and lifting a movable support column to the top of the collapse cavity and bearing a load. Mounting an initial supporting arch, and welding the initial supporting arch with the support column. Removing a hydraulic prop after the support column contacting the initial supporting arch is cut off and the load of the shield plate is transferred to a supporting shed. Mounting an exhaust pipe and a filling material pumping pipe, and pumping a filling material into a collapse cavity space.

摘要： A jack assembly comprises a cylinder defining an interior, a piston having a piston head slideably engaged with the interior of the cylinder, an extension chamber defined between the piston head and the interior, and a pressure relief assembly integrated proximate the piston head and defining a relief passageway in selective fluid communication with the extension chamber. When a fluid pressure in the extension chamber exceeds a certain level, the pressure relief assembly allows fluid to flow through the relief passageway. In one form, the pressure relief assembly comprises a valve body, a relief passageway defined within the valve body, a valve seat formed along the relief passageway, a plug configured to selectively engage the valve seat, an adjustment member moveable along the relief passageway, and a biasing member captured between the plug and the adjustment member to urge the plug toward the valve seat.

摘要： A pneumatic load balancing device having an inflatable reservoir establishing via an amplifier a pressure within a lift chamber that is sufficient to balance the weight of an object being lifted. The reservoir is inflated and deflated by inflation and deflation valves that may be operated from an operator control center proximal an end effector of the device. The valves may be actuated via pushbuttons or in a mutually exclusively fashion via a neutrally biased reciprocating actuator. The device allows loads of different weights to be lifted in a semi-automatic fashion with operator involvement to select the load balancing pressure. The device may have an air release system that closes a blocking valve in the event of release of the object and optionally in the event of a loss of air supply. The pressure within the lift chamber is thereby preserved and can be vented at different rates.
