Embodiment 1

[0020] Embodiment 1: As shown in the figure, a rope detection device for a multi-rope winding hoist, the bottom 5 is installed on the machine room foundation below the hoist drum 9 with expansion bolts, and the bottom 5 is installed on the base 5. There is a pair of rolling bearings 4, a hydraulic cylinder 7 is arranged between the rolling bearings 4, the bottom of the hydraulic cylinder 7 is set on the base 5 through the rotation of the pin shaft, and the support composed of the rotating shaft 3, the connecting rod 2 and the pressing rod 1 is set on the rolling bearing 4, Wherein, the rotating shaft 3 is fixed on the inner ring of the rolling bearing 4, and is fixedly connected with two pressing rods 1 parallel to the rotating shaft 3 through the connecting rod 2 perpendicular to the rotating shaft 3, and the two ends of the pressing rod 1 are connected to the connecting rods 2 respectively. , there is a certain gap between the two pressure rods 1, and the body of the pressure...

Embodiment 2

[0022] Embodiment 2: On the basis of Embodiment 1, this structure can be used in all the specifications of the multi-rope winding hoist, but the lengths of the pressure rods used in different specifications are different. For example: JKD-4×1.9, the diameter of the drum is 4m, the diameter of the wire rope is 45mm, the length of the connecting rod of the rope detection device is 300mm, and the adjusted length of the hydraulic cylinder is 200mm. Then it can be known by calculation that the distance between the pressure bar in the detection device and the outermost steel wire rope or the outer layer rope lining of the drum needs to be adjusted to be 22.5 mm; each additional layer of the drum steel wire rope requires a rotation angle of At this time, when the first layer is wound, it is necessary to set the adjustment amount of the oil cylinder to 200sin4.3=15mm; when the second layer is wound, it is necessary to set the adjustment amount of the oil cylinder to 215sin4.3=16.1mm; ...

Abstract

The invention discloses a rope arranging detection device used for a multi-rope winding type elevator. The rope arranging detection device is installed below a winding drum of the elevator and comprises a base, a hydraulic cylinder, rolling bearings, rotatable supports and a control system of the hydraulic cylinder, wherein the hydraulic cylinder and the rolling bearings are arranged on the base. One end of each support is provided with a rotating shaft rotationally supported on the corresponding rolling bearing, and the other end of each support is provided with a pressing rod parallel to the corresponding rotating shaft. Each pressing rod is fixedly connected with the corresponding rotating shaft through connecting rods. A piston rod of the hydraulic cylinder is rotationally connected with the rotating shafts and is provided with a force sensor. The rotating shafts drive the pressing rods at the end portions of the supports to swing under the drive of the hydraulic cylinder, so that the perpendicular distance between the pressing rods and a steel wire rope on the outermost layer of the winding drum is maintained at a set value. When the rope arranging detection device is used, when synchronous adjustment of the elevator fails and the steel wire ropes on the winding drum abut against the pressing rods, generated pressure triggers the force sensor, the force sensor is used for feeding back a signal to a master control system of the elevator, the master control system of the elevator sends out a shutdown signal, and a safety protection function is achieved.

Description

technical field [0001] The invention belongs to the technical field of mine hoists, in particular to a rope detection device for a multi-rope winding hoist. Background technique [0002] Mine hoist is one of the important and key equipment in mines. It is mainly used in coal mines, metal mines and non-metal mines for hoists and decentralized personnel to lift coal, ore, and transport materials and equipment. It is an important means of transportation to connect the well and the underground. It occupies a very important position in the mine and is an important equipment of the mine. [0003] With the increasing demand for mineral resources, there will be more and more hoisting equipment for deep and ultra-deep wells, making the design and development of multi-rope winding hoists and related equipment imminent. At present, there is no application case of the multi-rope winding hoist in China, and it has been in operation for many years in South Africa, Canada and other count...
