Description

Technical Field

[0001] The present invention belongs to the technical field of rescue equipment, and particularly relates to an aerial ropeway rescue device and method. Background Art

[0002] A cable car is a conveying device for lifting or lowering personnel and goods, and the cable car runs along an aerial ropeway. Once the cable car breaks down and cannot run, the people taking the cable car will be trapped in the air, and it requires a large amount of manpower, material resources and professional rescue personnel to rescue the trapped people back to the ground.

[0003] At present, aerial ropeway rescue includes two types: horizontal rescue and high-altitude vertical rescue. Horizontal rescue is a rescue method in which a rescue team is composed of multiple people with different divisions of labor. Some rescue personnel carry corresponding auxiliary rescue safety equipment and climb the steel frame to the rescue trolley on the aerial ropeway, and some other rescue personnel pull the rescue trolley on the ground to make the rescue trolley move along the aerial ropeway to the faulty cable car. The rescue personnel on the rescue trolley descend into the cable car through the auxiliary rescue safety equipment and carry out rescue operations on the trapped people.

[0004] High-altitude vertical rescue is a method of using an aircraft such as a helicopter to lower a ladder to the faulty cable car and take the trapped people away from the air. The cost of high-altitude vertical rescue is relatively high, aircraft are difficult to popularize, and it is limited by the rescue environment and weather. Therefore, at present, horizontal rescue is mainly used to rescue the trapped people on the aerial ropeway, but there are still the following deficiencies in ground rescue:

[0005] 1. The rescue equipment is relatively cumbersome and heavy. It requires multiple rescue personnel to wear heavy climbing equipment and climb the cableway steel frame before they can move along the aerial cable to the rescue location; the process is high-risk, time-consuming and laborious, and it is a high-altitude hanging parallel movement operation.

[0006] 2. More rescue manpower is needed. Conventional aerial ropeway rescue requires about 6 - 10 people, and even more affiliated supporting divisions of labor.

[0007] 3. Traditional rescue requires climbing the cableway columns, passing through the cable wheels or straddling multiple hanging devices to reach the rescue position. The high-altitude operation of climbing is cumbersome and there are many protective devices, and it is impossible to reach the rescue hanging device in a short time to carry out rescue work.

[0008] 4. During the rescue period, multiple people assist the main rescue personnel to move to the rescue position through sliders, which is time-consuming and laborious in the air, and the work efficiency is relatively slow.

[0009] 5. When reaching the aerial rescue position for high-altitude rescue, two people are needed to assist in descending to the rescue hanging device position. It is relatively dangerous to carry out the initial operation of climbing in a narrow space with mutual assistance. Summary of the Invention

[0010] The object of the present invention is to provide an aerial ropeway rescue device and method, so as to solve the problem that multiple rescue personnel need to wear climbing equipment to climb the ropeway steel frame and then move along the aerial cableway to the faulty cable car during aerial ropeway rescue, and the rescue procedure is complex and the efficiency is low. The technical solution adopted by the present invention is as follows:

[0011] An aerial ropeway rescue device includes a cantilever and a rescue device; the rescue device includes an outer box body, a fixed clamping plate and a roller wire shaft. The outer box body is a box body with a lower opening, a lower flap is hinged to the bottom of the outer box body, the fixed clamping plate is arranged in the middle of the outer box body, the fixed clamping plate divides the outer box body into an upper part and a lower part, a rope passing roller shaft is rotatably arranged in the upper part of the outer box body, two wire passing holes are arranged on the fixed clamping plate, one end of a traction rope passes downward through one wire passing hole and is tied to the roller wire shaft, the other end of the traction rope first bypasses the rope passing roller shaft and then passes downward through the other wire passing hole and is tied to the roller wire shaft, and the rescue device is connected to the cableway suspension arm of the cable car through the cantilever;

[0012] When the cable car is running normally, the lower flap closes the lower opening of the outer box body and is locked through a wire locking device, and the roller wire shaft is suspended in the lower part of the outer box body; when aerial ropeway rescue is carried out, the lower flap is opened and the roller wire shaft drops to the ground.

[0013] Further, the wire locking device includes a handle, a wire, a lock seat and a pin shaft. The lock seat is arranged on the lower flap, a counterbore is arranged on the lock seat, a first through hole is machined at the bottom of the counterbore, a lock cover is connected to the lock seat, a second through hole coaxial with the first through hole is arranged on the lock cover, a shoulder is arranged in the middle of the pin shaft, one side of the shoulder of the pin shaft is a pin joint section and the other side is a pulling section, the pin joint section of the pin shaft is in sliding fit with the first through hole, the pulling section of the pin shaft is in sliding fit with the second through hole, a return spring is sleeved on the pulling section, and two ends of the return spring respectively abut against the lock cover and the shoulder. The handle is arranged in the cable car, one end of the wire is connected to the handle and the other end is connected to one end of the pulling section far away from the shoulder, a lock nose is arranged on the outer box body, and one end of the pin joint section far away from the shoulder is pin-jointed or separated from the lock nose.

[0014] Further, one end of the cantilever is provided with a fixing frame, the fixing frame is fixed on the cableway suspension arm of the cable car through a U-shaped bolt, and the rescue device is fixedly welded to the other end of the cantilever.

[0015] Further, the fixing frame is connected to the rescue device through a safety rope.

[0016] Further, the cantilever includes a fixed arm and a telescopic arm connected coaxially. A set of fixing holes is arranged on the fixed arm, and a plurality of sets of adjusting holes are arranged on the telescopic arm along the length direction. The set of fixing holes is matched with any set of adjusting holes through bolts.

[0017] Further, a spare safety rope hanging ring is arranged on the cantilever.

[0018] Further, a waterproof cover plate is arranged on the outer box body.

[0019] Further, the waterproof cover plate and the outer box body are connected by magnetic attraction.

[0020] The present invention also provides an aerial ropeway rescue method, which is realized based on the above-mentioned aerial ropeway rescue device, and includes the following steps:

[0021] Step 1: The rescue personnel rush to the ground below the faulty cable car, and guide the trapped people in the cable car to unlock the cable locking device. The lower flap is opened under the action of gravity, and the wire roller shaft drops to the ground.

[0022] Step 2: Unfasten one end of the towing rope, connect it to the main rescue rope, and pull the other end of the towing rope to lift the main rescue rope by the towing rope, and make the main rescue rope first pass through one wire passing hole, then bypass the rope passing roller shaft and pass back through the other wire passing hole, and finally make both ends of the main rescue rope fall back to the ground.

[0023] Step 3: Insert a retaining ring into one end of the main rescue rope, tie a knot below the retaining ring, set a rope ascender at the other end of the main rescue rope, pull the main rescue rope for assistance, so that the retaining ring is stuck between the corresponding wire passing hole and the knot. One rescue personnel holds one end where the rope ascender is set, and the other rescue personnel can ascend to the faulty cable car by relying on the rope ascender to rescue the trapped people.

[0024] Further, the retaining ring can be cancelled. When holding one end of the main rescue rope where the rope ascender is set, make the knot stuck at the corresponding wire passing hole.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] The present invention is an aerial ropeway rescue device. When the rescue personnel arrive at the ground below the faulty cable car, the rescue personnel guide the trapped people to pull the handle of the cable locking device through means such as a cableway column loudspeaker, a telephone, and a ground-to-air intercom, so that the cable locking device is opened. The lower flap at the bottom of the outer box body flips by itself under the action of gravity, so that the wire roller shaft drops to the ground. The main rescue rope is lifted by the towing rope and bypasses the rope passing roller shaft and returns to the ground, achieving the purpose of replacing the towing rope with the main rescue rope. When the main rescue rope is clamped and fixed with the fixed clamping plate, the rescue personnel can use the rope ascender to ascend along the main rescue rope to the faulty cable car to rescue the trapped people. Through the present invention, when the rescue personnel arrive at the ground below the faulty cable car, they can quickly carry out the rescue. Unlike traditional ground rescue, it is not necessary for multiple rescue personnel to carry rescue equipment and climb the cableway steel frame and then move along the aerial ropeway to the faulty cable car. Using the present invention, only two rescue personnel are required to carry out the aerial ropeway rescue task, and the rescue procedure is simple and efficient, and the reaction speed is fast.

Detailed implementation manners

[0037] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described below through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and do not limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present invention.

[0038] The connections mentioned in the present invention are divided into fixed connections and detachable connections. The fixed connection is an inseparable connection, including but not limited to conventional fixed connection methods such as hemming connection, rivet connection, bonding connection, and welding connection. The detachable connection includes but not limited to conventional disassembly methods such as bolt connection, snap connection, pin connection, and hinge connection. When the specific connection method is not clearly defined, it is defaulted that at least one connection method can be found among the existing connection methods to achieve this function, and those skilled in the art can choose according to their needs. For example: welding connection is selected for the fixed connection, and bolt connection is selected for the detachable connection.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings. The following embodiments are explanations of the present invention, and the present invention is not limited to the following embodiments.

[0040] Embodiment 1: As Figures 1-7 shown, an aerial ropeway rescue device includes a cantilever 1 and a rescue device 2; the rescue device 2 includes an outer box body 21, a fixed clamping plate 27, and a wire roller shaft 22. The outer box body 21 is a box body with a lower opening. A lower flap 23 is hinged to the bottom of the outer box body 21 to open or close the lower opening of the outer box body 21. The fixed clamping plate 27 is arranged inside the outer box body 21. The fixed clamping plate 27 divides the outer box body 21 into an upper part and a lower part. A wire passing roller shaft 25 is rotatably arranged in the upper part of the outer box body 21. Two wire passing holes 28 are provided on the fixed clamping plate 27. One end of a traction rope 26 passes downward through one wire passing hole 28 and is tied to the wire roller shaft 22.
