    Abstract: The present invention discloses a device and method for adjusting tension of a steel wire rope of an ultra-deep vertical shaft at a hoisting-container-end. The device includes two stages of steel wire rope tension adjusting devices provided on a hoisting container, where a primary steel wire rope tension adjusting device includes left and right steel wire rope tension adjusting devices that are symmetrically arranged, and a secondary steel wire rope tension adjusting device is provided below the primary steel wire rope tension adjusting device. By use of two stages of steel wire rope tension adjusting devices, tension on four steel wire ropes can be adjusted to equalize the tension, thus meeting the requirement for tension equalization in a hoisting process. The four steel wire ropes are equally divided into two groups. Tension of two steel wire ropes is adjusted by rotating a primary drum around which the two steel wire ropes are wound, and then tension of the four steel wire ropes is adjusted by rotating a secondary drum around which the multiple steel wire ropes are wound, thus achieving a final purpose. The device of the present invention has a simple structure, and is conveniently mounted and easily detached. The tension is automatically adjusted by rotating the drums. This solution is novel and has wide application.

    Abstract: The present invention discloses a self-detection device for a liner plate of a hoisting container and a detection method. The device mainly includes: a frame, a baffle-type hoist conveyor, a horizontal conveyor, a loading hopper assembly, an unloading hopper assembly, a liner plate assembly, and a hoisting container system. The loading hopper assembly is fixedly mounted to an upper right end of the frame, the unloading hopper assembly is fixedly mounted to a lower left end of the frame, the hoisting container system is arranged on an upper left portion of the frame and above the unloading hopper assembly, and the liner plate assembly is provided inside the hoisting container system. A feed port of the baffle-type hoist conveyor is connected to an unloading port of the unloading hopper, and a discharge port thereof is joined to a loading port of a loading hopper; and a feed port of the horizontal conveyor is connected to an unloading port of the loading hopper, and a discharge port thereof is arranged at a feed port on an upper end of the hoisting container system. The self-detection liner plate can simulate an impact, friction, and wear behavior on a liner plate of a hoisting container in an actual loading process; and can measure in real time an impact force and friction force bored by the liner plate when a material falls down to impact on the liner plate. In addition, the self-detection liner plate enables continuous loading of materials.

    Abstract: 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.
