    摘要: A hoist main shaft torque monitoring device based on angle measurement, constituted primarily by a first base, a second base, a light generating unit, a shutter, and a light sensing element; the light source, a first lens, and a first optical aperture arranged in the light generating unit, as well as a second optical aperture, second lens, and light sensing element on the shutter, forming a light source generation, propagation, and reception pathway; when the elevator main shaft is subjected to a certain torque, a corresponding displacement is produced between the first optical aperture and the second optical aperture, thus measuring the change in amount of light ultimately reaching the second optical aperture so as to measure the twist angle of the rotary shaft and finally calculate the magnitude of the shaft torque. Without damaging the original equipment and foundation, the device measures the torque of the shaft at different rotational speeds. The device can measure stationary torque and torque at different rotational speeds of the shaft, without the electromagnetic field interfering with wireless transmission; the device is easy to use, maintenance costs are low, and it is of interest for widespread popularization.

    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.

    摘要: An elevator anti-fall buffer based on flexible guidance. The anti-fall buffer is used for connecting and fixing an end part of a braking steel rope of an elevator. The anti-fall buffer has an upper support plate and a lower support plate, wherein a pulley set is provided on the upper support plate and the lower support plate, and a hydraulic damping buffer is provided at two sides of the pulley set. The anti-fall buffer uses the energy consumption principle of a hydraulic damping hole, and while protecting the braking steel rope from the force of impact created thereon by the elevator, prevents the force of impact from a spring on the elevator post-braking, improving the safety and reliability of elevator braking, thereby improving safety of an elevator, while also using a pulley set can increase the braking distance of the braking steel rope, thereby lengthening life of the steel rope.

    摘要: A fracture detection system and method for a dumbbell pin of a scraper conveyor. The system comprises a scraper conveyor, a wireless ranging apparatus (2), a wireless communication device, a support controller and a monitoring center. The wireless ranging apparatus (2) is mounted on a ramp plate ledge of a scraper conveyor chute (1), and has a laser range finder and a reflection target plate (24) for detecting a relative displacement between any two adjacent chutes. The wireless communication device realizes communication between the wireless ranging apparatus (2) and the support controller, and transmits the displacement of the laser range finder to the support controller in a wireless transmission manner. The support controller controls an action of the scraper conveyor chute (1). A monitoring center is electrically connected to the support controller, and can perform storage processing on relative displacement data of any adjacent chutes. In the method, by taking a relative displacement value between adjacent chutes as a reference, whether a fracture fault occurs in a dumbbell pin is judged, the position of the fractured dumbbell pin can be accurately determined, and a support controller controls a chute action, thereby having a high promotion and usage value.

    摘要: An intelligent charger with a diagnostic function and a charging method. The intelligent charger includes a control module, a diagnosis module, a charging module, a multi-path switch and a detection module. The control module is sequentially connected to the diagnosis module, the charging module and the multi-path switch; and the detection module is sequentially connected to an external connection terminal of a battery, the multi-path switch and the fault diagnosis module. The charging method includes a charging mode and a diagnosis mode; the diagnosis mode includes a two part function, namely fault diagnosis and lifetime detection; the fault diagnosis is detecting a fault problem which can occur in the battery and providing a prompt; and the lifetime detection is detecting the current capacity of a battery, and determining current battery life through the ratio of current capacity to rated capacity.
