Embodiment 1

[0036] This embodiment discloses a split rope arrangement suitable for large pitch angles, such as Figure 1 to Figure 4 As shown, the device includes a safety rope guide 31 , a first moving mechanism 32 that drives the safety rope guide 31 to move, and a second moving mechanism 33 that drives the first moving mechanism 32 to move. The moving direction of the safety rope guide 31 on the first moving mechanism 32 is along the axial direction of the hoisting drum 2 . Preferably, the moving length of the safety rope guide 31 on the first moving mechanism 32 is the same as that of the hoisting drum 2 . The axial width of the hoisting drum is the same, so as to realize the full coverage of the width of the hoisting drum by the rope arrangement of the rope arrangement device. The moving direction of the first moving mechanism 32 on the second moving mechanism 33 is along the safety rope 5 . Specifically, the first moving mechanism 32 is connected to the second moving mechanism 33 th...

Embodiment 2

[0047] This embodiment discloses a lifting system suitable for large pitch angles, such as Figure 5 As shown, the hoisting system includes a boom 1 , a hoisting drum 2 , the rope arrangement 3 described in Embodiment 1, and a roller 4 arranged at the top of the boom 1 . Wherein, the second moving mechanism 3 of the rope arranging device 3 is connected to the side of the boom 1 , and the moving direction of the first moving mechanism 32 on the second moving mechanism 33 is along the length direction of the boom 1 . Specifically, the second support 331 of the second moving mechanism 33 is fixed to the boom by welding or bolting.

[0048] Through the cooperative action of the first moving mechanism 32 and the second moving mechanism 33, the safety rope can reach any point on the plane below the lifting arm, so as to realize the dynamic adjustment of the safety rope at the hoisting position when the rope is withdrawn.

[0049] In order to realize the automatic control process of...

Embodiment 3

[0054] This embodiment discloses a hoisting system control method suitable for large pitch angles. This method adopts the hoisting system described in Embodiment 2 to control the rotation speed of the hoisting drum and the movement of the safety rope guide 31 during the hoisting and lowering of the safety rope. Coordinated speed control.

[0055] During the coordinated control process of rope arranging and hoisting of the whole rope arranging device, the key parameter that needs to be guaranteed is that the speed v of the hoisting or lowering of the safety rope remains unchanged.

[0056] Let the hoisting speed of the safety rope be v, in the uncoiled state, the initial rope diameter of the hoisting drum is D, and the winding speed of the first row of ropes in the drum under the uncoiled state in the initial state no 1 is the initial reference speed of the hoisting drum; the rotation period of the hoisting drum

[0057] Split-type rope arrangement device in a rope winding...

Abstract

The invention discloses a split rope arrangement, a lifting system and a control method suitable for large pitch angles, including a boom, a hoisting drum, a rope arrangement, and a roller arranged on the top of the boom, wherein the rope arrangement includes a safety rope The guide, the first moving mechanism that drives the safety rope guide to move, and the second moving mechanism that drives the first moving mechanism to move; the moving direction of the safety rope guide on the first moving mechanism is along the axial direction of the hoisting drum, and the The moving direction of the first moving mechanism on the second moving mechanism is along the direction of the safety rope; the safety rope guide includes a housing and a guide wheel arranged in the housing, and the housing is provided with a rope opening for the safety rope to pass through; the housing A connecting piece is hinged on the body, and the connecting piece is connected with the first moving mechanism. It overcomes the defects of the single rope shape of the fixed rope puller in the lifting mechanism with a large pitch angle, avoids the occurrence of disordered ropes and wear of the safety rope caused by the discomfort of the rope shape during the process of changing the pitch angle, and ensures the safety of personnel and workers during the lifting process. Device Security.

Description

technical field [0001] The invention belongs to the technical field of mine rescue equipment, and in particular relates to a split rope arranging device, a hoisting system and a control method suitable for a large pitch angle. Background technique [0002] When an accident occurs underground in a coal mine and the miners are trapped, the mine safety rescue hoisting vehicle conducts vertical drilling from the ground straight to the underground tunnel of the coal mine, and lowers the rescue hoisting cabin to perform underground rescue. Because the mining areas are mostly in the wild and other mountainous areas, the ground conditions are complex and diverse, and the ground is often uneven or the rescue vehicle cannot approach. At this time, it is necessary to adjust the boom posture of the rescue vehicle and increase the boom angle to achieve long-distance delivery of the rescue lift cabin. . Due to the large pitch angle of the hoisting system, the pitch angle tends to change ...
