Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine devices, in particular to an overhead passenger device rescue hanging chair for coal mines. Background Art

[0002] Aerial passenger cars for coal mines, commonly known as "monkey cars," are specially designed for transporting personnel underground in coal mines, primarily in inclined or horizontal lanes. The operating principle of these devices is similar to that of tourist cableways on land. A rope grip connects a passenger chair to an overhead, endlessly circulating steel wire rope, enabling a circular motion to transport personnel. The main components of an aerial passenger car for coal mines include a drive unit, a tailwheel and tensioning device, a passenger section, a rope support, an electrical control system, and integrated protection devices.

[0003] The design of the overhead passenger device takes into account the characteristics of safe and reliable operation, convenient personnel up and down, simple operation, easy maintenance, low power consumption, high transportation efficiency and low one-time investment. It is a new type of modern coal mine underground personnel transportation equipment.

[0004] For years, many coal mines have adopted "monkey carts" (also known as overhead passenger vehicles) to replace manual or manned transport in inclined shafts to reduce the physical exertion of workers going up and down the mines. These carts are popular with many mines due to their speed and convenience in transporting personnel. However, both the manufacturer and most mines have overlooked a crucial issue: the installation of equipment to transport the injured or sick. If an injury occurs in a coal mine, the injured or sick can only be transported to the surface on stretchers, hundreds of meters underground, up the steps. This not only delays treatment time but also increases the workload of the transporters.

[0005] CN201711280136.2 discloses an aerial rescue stretcher for carrying passengers in underground mines, comprising a foldable stretcher bed, an opening, a first pull rod, a second pull rod, a first safety belt, a second safety belt, a first suspension rod, a second suspension rod, a steel wire rope, a ring, a first nylon rope, and a second nylon rope; the first pull rod and the second pull rod are respectively arranged at the left and right ends of the foldable stretcher bed and connected to the foldable stretcher bed; the opening is arranged in the middle of the foldable stretcher bed; the first safety belt and the second safety belt are respectively connected to the middle of the right end and the middle of the left end of the foldable stretcher bed. However, this device has problems with the inconvenience of installing an aerial rescue stretcher and the instability during transportation. Utility Model Content

[0020] The present invention will be further described with reference to the accompanying drawings.

[0021] As shown in the figure, a rescue chair for an overhead passenger device used in coal mines includes two retractable booms. The top of the retractable booms is connected to a rope grip 1, and the bottom is provided with two forks 2. The ends of the forks 2 are provided with springs 3 for shock absorption. The function of the springs 3 is to increase the comfort of the rescued personnel. A bed frame is provided on the upper surface of the springs 3, and a connecting rod 4 is provided between the retractable booms. The two ends of the connecting rod 4 are respectively provided with a connecting ring 1, and the retractable boom is provided with a connecting ring 2. The connecting rod 4 and the retractable boom are connected through the connecting ring 1 and the connecting ring 2. By providing the connecting rod 4, the two retractable booms can be twisted to different angles, but will not separate, and will maintain a square state with the bed frame, so that the distance between the upper parts of the two hanging chairs will not increase or decrease at any time.

[0022] Furthermore, the telescopic boom includes boom 1 5 and boom 2 6 , boom 1 5 extends into boom 2 6 , and a plurality of adjustment holes are provided on the surfaces of boom 1 5 and boom 2 6 , and positioning pins for fixing are provided in the adjustment holes.

[0023] Furthermore, the connecting end between the telescopic boom and the rope grip 1 is hollow, the hollow end of the telescopic boom extends into the rope grip 1, a fixing hole is provided on the hollow surface, and a fixing pin is provided in the fixing hole for fixing.

[0024] Furthermore, the forks 2 at the bottom end of the telescopic boom are located in the same horizontal plane.

[0025] Furthermore, the bed frame includes a bottom plate 7, with guardrails 8 fixedly connected to the left and right sides and the rear side of the bottom plate 7, and a foldable side guardrail 9 connected to the front side of the bottom plate 7 via a rotating shaft. When transporting people, the guardrails can protect people from falling off the bed frame.

[0026] When in use, the retractable boom is connected to the rope grip according to the transportation mode of different overhead passenger devices; the positioning pin hole in the middle of the retractable boom is adjusted according to the inclination angle of the tunnel to keep the center of gravity of the bed frame under the rescue hanging chair in a horizontal state; the person is placed on the bed frame and surrounded by guardrails on all four sides to ensure that the person will not fall during transportation; the shock absorber under the bed frame ensures that the rescued person has a certain degree of comfort during transportation.

[0027] According to actual tests, if an injury accident occurs in a coal mine, it takes 90 minutes to carry the injured or sick from the 630 level up the stairs to the mine entrance using a manual stretcher. Considering the physical strength of the rescue workers, six people are required to take turns.

[0028] After using this rescue chair, it only takes 9 minutes to transport the injured or sick from the 630 level to the wellhead, and 2 rescue workers are required to accompany them.

[0029] The use of the rescue hanging chair greatly shortens the rescue time of the wounded, the labor intensity and the number of rescuers, and greatly increases the survival probability of the rescued people.
