Abstract

A rope anti-reverse device for a suspension descending system is disclosed, a unidirectional rotating member clinging to a rope groove (7.1A) of the slide rail (7.1) is used. The turning radius of a unidirectional rotating assembly (7.3) is greater than the distance from the rotary center to a slide rail rope (1.2B). When the unidirectional rotating assembly turns, the slide rail rope is compressed. When the rope (1.2B) moves upward, the unidirectional rotating member rotates normally. When the rope moves downward, the unidirectional rotating member stops reversely. Due to the friction generated between the unidirectional rotating member and the rope, the unidirectional rotating assembly turns till the rope is compressed. Thereby, the problem of affecting operation in current board-type lifting tool for single person, that the rope at the free end (the end of the rope freely drooping to the ground) slides down driven by the gravity, as long as released form hand, weather the operator lifts the rope upward or pulls the rope downward, is overcome.

Description

Rope reversing device for hanging down system

Technical field

The present invention relates to a suspension descent system, and more particularly to a rope fall prevention device for a suspension descent system that is manually controlled by gravity of the human body.

Background technique

In the practice of cleaning the exterior wall, the seat-type single-purpose spreader is usually used. When using it, first select a fixed place for the rope at the top of the building.

Say

Put all the ropes at the corners, ribs and laps with a rubber sole to prevent the abrasion of the slings; then hang the slings in the lowers of the slings to make a special knot. Because there is such a special knot, in the work, the hanging plate will not slide down, and the person can control the rope and can operate freely. To put it simply, when you lift the rope and the hanging plate, it will slide down a little, how many books will be slipped, how fast and how fast, until the end of the work. This tool can also be used in high-altitude exterior wall painting projects. Due to the use of the spreader, the user has to carry out the construction operation in addition to the operation of the rope, and the work is dangerous because of the work at height. High-altitude operators using seat-type single-slingers must be male citizens who are 18 years of age or older, have undergone physical examination and safety technical training, and are qualified to pass the examinations. Workers must not drink alcohol before they are employed, and have symptoms such as a cold. Work at height must be suspended. The advantage of the seat type single-purpose spreader is that it is simple in structure and convenient to operate. If the safety measures are done well, it is safe to use.

In order to standardize the terminology, the names of various types of parts in this article refer to the relevant materials of “Safety Technical Specifications for Seat-type Single Spreaders for Building Exterior Wall Cleaning Work”. The suspension descent system is mainly composed of a working rope, a descender, a connector, and a seat plate device. Dropper: A device that is mounted on a working rope and powered by the operator's own weight and controlled by hand. The types of descenders include: rod, multi-plate, splayed and shackle type, among which shackle type lowers Commonly known as U-shaped crab buckle. Connector: A ring-like part with a normally closed valve that connects the internal parts of the system together. Seat plate device: A device for carrying workers, consisting of a sling, a lining and a seat plate.

Since the seat type single-purpose spreader is used to make a special knot in the lowering device, and the knot is tightened by the weight of the lower end rope itself, the seat plate and the human body are fixed and suspended in the air, and when it is required to descend, the operator The special knot end rope must be lifted up so that the special knot is not tightened. At this time, the human body is lowered, the rope is lifted, the human body is falling down, the rope is lifted faster, and the human body is falling faster. When the height of the building is very high, the rope needs to be very long. At this time, the weight of the rope is also very large. When the rope exceeds 100 meters, the weight of the rope will exceed 25 kg, and it will be difficult to lift the rope upwards. To this end, I have developed a spreader that uses a method of pulling down the rope to achieve a reduction in the human body. However, whether it is lifting the rope or pulling the rope down, when the hand releases the rope, the free end of the rope (the rope that is free to hang down to the end of the ground) will slide downward under the action of gravity, affecting the operation.

Summary of the invention

In order to overcome the current seat-type single-use spreader, when the operator lifts the rope or pulls the rope down, when the hand loosens the rope, the free end (freely hangs down to the end of the ground rope) in the role of gravity Will go down, affecting the operation of the problem, the present invention A rope anti-reverse device for hanging down the system, which utilizes a one-way rotating member that runs close to the rope. When the rope is running upward, the one-way rotating member rotates normally. When the rope runs downward, the one-way rotating member is reversed. Backward, stop the rope from running in reverse.

The technical solution adopted by the present invention is to provide a rope anti-reverse device for a suspension descent system according to the present invention, comprising: a slide rail fixed to the fixed plate, a fixing base, at least one one-way rotating component, and one-way rotation The assembly is mainly composed of a one-way rotating member, an axle, a wheel base and a rotary shaft. The one-way rotating member is mounted on the wheel base through the axle, and the one-way rotating assembly is mounted on the fixed plate through the rotary shaft, and the rope passes through the sliding rail. The one-way rotating member is closely attached to the rail rope. The radius of gyration of the one-way rotating component is greater than the distance from the center of rotation to the rail rope. When the one-way rotating component rotates, the rail rope will be compressed, when the rope is running upwards. The one-way rotating member rotates normally. When the rope runs downward, the one-way rotating member reverses the reverse direction, and the frictional force generated between the one-way rotating member and the rope causes the one-way rotating assembly to rotate until the rope is pressed.

According to one of the preferred aspects of the present invention, the slide rail is provided with a rope groove for accommodating the rope.

According to a second aspect of the present invention, the rope groove is provided with an anti-slip hole.

According to a third aspect of the present invention, the outer cylindrical surface of the one-way rotating member is coated with a non-slip rubber layer.

According to a fourth aspect of the present invention, the outer cylindrical surface of the one-way rotating member is provided with an inner concave surface matching the rope.

According to a fifth aspect of the present invention, the one-way rotating member is a one-way bearing.

According to a sixth aspect of the present invention, the one-way rotating member is a rotating wheel in which a one-way bearing is built.

According to a seventh aspect of the present invention, the one-way rotating member is placed on the rope of the sliding rail by gravity.

According to a preferred embodiment of the present invention, an elastic member is further disposed between the fixing plate and the fixing base, and the one-way rotating member abuts against the rope of the sliding rail under the action of elasticity.

Nineth Preferred Aspect of the Invention: A wire guide member is further provided at the rope entrance and exit of the slide rail.

According to a tenth aspect of the present invention, the guide member is a U-shaped hook fixed to the fixing plate.

According to a tenth aspect of the present invention, a pad member is further disposed between the slide rail and the fixed plate, and the height of the slide rail is adjusted by the pad member to cooperate with the one-way rotating member.

The utility model has the beneficial effects that, by using the one-way rotating member running against the rope, when the rope is running upward, the one-way rotating member rotates normally, and when the rope runs downward, the one-way rotating member reversely reverses to prevent the rope from running. , can effectively prevent the free end of the rope from sliding down.
