Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of aerial passenger ropeways, and in particular relates to an anti-rope-off protection device for an aerial passenger vehicle. Background Art
[0002] Overhead passenger cars are commonly known as monkey cars. They are mainly used to assist in transporting workers in underground mines. The wire rope is installed on the driving wheel, rope support wheel, rope pressure wheel, and detour wheel and is tightened by the tensioning device. The driving device outputs power to drive the driving wheel and wire rope to run, thereby realizing the principle of transporting miners.
[0003] When the overhead passenger car is working, due to the large slope of some lanes and the large number of slope change points, the wire rope on the rope wheel will easily be pulled due to the large up and down swing amplitude. If the wire rope is not stopped immediately after it is detached from the rope pulley, it will affect the safety of the passengers. The rope catching hook in the existing overhead passenger car anti-rope detachment protection device is fixed. If the rope catching hook is too long, it will hinder the passage of the overhead passenger car. If it is too short, the rope catching hook may not be able to catch the rope, affecting the rope catching effect. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an anti-rope-off protection device for an overhead passenger vehicle, which solves the technical problems of the influence of the rope catching hook on the overhead passenger vehicle or the poor rope catching effect in the existing anti-rope-off protection device.
[0005] In order to solve the above problems, the technical solution of the present invention is: an anti-rope-off protection device for an overhead passenger vehicle, which includes a rope catching device and a sensor, wherein the rope catching device includes a mounting frame, a rope catching hook and a tension spring; the sensor is arranged on the left side of the top surface of the mounting frame;
[0006] The mounting frame is arranged horizontally, a rope-supporting wheel shaft through hole is arranged in the middle of the mounting frame, a vertical rotating shaft is arranged on the right side of the mounting frame, a rotating sleeve is sleeved on the vertical rotating shaft, the rope-catching hook is arranged horizontally, and its tail end is connected to the lower part of the side wall of the rotating sleeve; the rope-catching hook and the rotating sleeve rotate around the vertical rotating shaft;
[0007] A horizontal sleeve is provided at the middle position of the bottom of the mounting frame, a fixing ring is provided on the right side of the horizontal sleeve, the horizontal sleeve and the fixing ring are respectively fixedly connected to the mounting frame, one end of the tension spring is connected to the mounting frame on the left side of the horizontal sleeve, and the other end of the tension spring passes through the horizontal sleeve and the fixing ring in sequence and is connected to the tail end of the rope catching hook;
[0008] A return spring is provided between the side wall of the rotating sleeve and the mounting bracket on the left side of the rotating sleeve;
[0009] The contact rod of the sensor, the rope catching hook and the rope supporting wheel are all arranged on the front side of the mounting frame; and the top of the rope supporting wheel is higher than the contact rod of the sensor.
[0010] Furthermore, when the tension spring and the return spring are in a natural state, the rope catching hook is perpendicular to the steel wire rope.
[0011] Furthermore, the mounting frame is a channel steel structure, and the contact rod of the sensor, the rope catching hook and the rope supporting wheel are all arranged on one side of the opening of the notch of the mounting frame.
[0012] Furthermore, a notch is provided on the mounting frame above the through hole of the rope supporting wheel shaft for preventing the supporting rope from interfering with the mounting frame.
[0013] The present invention adopts the above technical solution. After the steel wire rope is separated from the rope support wheel, it first contacts the contact rod of the sensor, triggers the sensor, and then the system automatically stops. The steel wire rope then falls into the rope catching hook, which supports the steel wire rope and avoids the safety hazard caused by the steel wire rope falling. When the overhead passenger car passes through the rope support wheel, the rope catching hook is pressed to one side, which will not affect the overhead passenger car. After the overhead passenger car passes, the rope catching hook returns to its original position under the action of the tension spring and the reset spring to continue to protect the steel wire rope. Compared with the prior art, the present invention has the advantages of simple structure, reasonable design, safe and convenient use, etc. BRIEF DESCRIPTION OF THE DRAWINGS
