An adjustable intermediate disk body of large double-layer cage comprises cage columns, a main intermediate disk body, and a chain block and a connecting piece. An intermediate disk guide rail beam is arranged on the inner side of the cage columns, wedge bases are symmetrically arranged on the two sides of the lower part of the intermediate disk guide rail beam, a limited block with a bolt hole is arranged on the upper part of the intermediate disk guide rail beam, and an anti-disengaging plate is arranged on the intermediate disk guide rail beam. Intermediate disk wedge bodies, which match the wedge faces of the wedge bases and can only move vertically along the intermediate disk guide rail beams, are arranged on the two side faces of the main intermediate disk body, at positions corresponding to the intermediate disk guide rail beams; an intermediate disk guide wheel that is fitted with the intermediate disk guide rail beam and an intermediate disk guide wheel seat with a bolt hole are arranged on the upper part of the intermediate disk wedge body.

A device for monitoring tension equalization and displacement adjustment states of steel wire ropes of a multi-rope hoister includes a displacement sensor mounted on a steel wire rope tension equalization device, a signal acquisition transmitter designed to store and transmit signals of the displacement sensor, a barometric altimeter designed to detect the depth of a mine shaft where a hoisting container is located, and a wireless receiving and processing system arranged at the well mouth of the mine shaft. A method for use includes collecting the displacement adjustment amounts of the tension equalization devices connected with all the hoisting ropes of the hoisting container and the corresponding depth position of the hoisting container during the up-down running process of the hoisting container by means of the signal acquisition transmitter; judging the maximum displacement adjustment amount measured in the entire hoisting process and the corresponding tension adjustment device and corresponding depth, by receiving and processing data via the wireless receiving and processing system; and, giving an alarm when the maximum adjusted displacement is greater than a preset adjustment threshold.

摘要:
The present invention provides a large-tonnage slender externally powered rail-mounted unloading skip, comprising an upper bin body and a lower bin body that are respectively formed by an inner lining plate and an outer plate fixed together via a number of pin shafts, a self-locking gate, and a gate opening device. A loading opening and a coal baffle plate that is used to block coal when the coal is loaded are arranged on the upper part of the upper bin body, a self-locking gate composed of a sector gate plate and unloading rollers is arranged on the lower bin body, a coal chute is arranged on the lower part of the self-locking gate, the upper bin body and the lower bin body are connected together through flanged connection, and channel irons are welded around the walls of the upper bin body and lower bin body respectively; when the skip is at an unloading position, externally powered telescopic push rods push the unloading rollers to move in an unloading rail of the slide block, so that the self-locking gate is opened, and the coal is unloaded along a coal chute. With the reliable connection between the upper bin body and the lower bin body, effective and convenient fixing of the lining plate, and reliable opening of the gate, the skip can meet the production requirements of 10-million tonnage large-size shafts.
