Description

Suspension descent system

Technical field

The present invention relates to a suspension descent system, and more particularly to a dangling 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 of the rope at the top of the building, and use rubber for all the corners, ribs and joints of the rope. Bottom, to prevent abrasion and wear of the sling; then put a special knot on the sling in the lowering of the seat sling. 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 much slippery, 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. Personnel who are generally responsible for exterior wall cleaning are required to be physically strong and trained to allow operation. The relevant technical specifications specify this. The problem is that when using the spreader, the operator must lift the rope when it needs to descend. If the height of the building is relatively high, the rope needs to be long and the weight is very large. It takes a lot of effort to lift the rope upwards. . Therefore, it is very difficult for people who are not trained or have insufficient strength to use existing technology products for operation.

Summary of the invention

In order to overcome the current use of the seat type single-use spreader, it takes a lot of effort for the operator to lift the rope upwards, and for the untrained person, there is a problem of difficulty in operation, and the present invention proposes a suspension. Drop system, which changes the rope by adding a rope guide When the operator descends, instead of lifting the rope up, he pulls the rope down, because when the operator is hanging in the air, whether it is in the upright hanging position or the seat hanging posture, pull down the rope. It is more convenient and better to use than to lift the rope.

The technical solution adopted by the present invention is a suspension descent system proposed by the present invention, which mainly comprises a working rope, a descender, a connector, and a loading device, and the working rope is marked with a special knot on the descender.

At this time, the rope at the end of the rope is changed from the tension state to the slack state, and the human body begins to descend. The free end of the rope is lifted up. Because the operator is suspended in the air, whether it is in a suspended position or in a seated position, it is better to pull the rope down than to lift the rope, which is not only easy to operate, but also safe and reliable.

One of the preferred aspects of the invention: the wire guide member is a hook member. As long as the working rope can bypass the hook and slide on the hook, the safety hooks produced by the manufacturer of the seat belt accessories can be applied or can be applied without any creative changes.

According to a second aspect of the present invention, a second guide member is further disposed on the fixing plate, and the working rope bypasses the second guide member after putting a special knot on the descender, and then bypasses the first guide rope. The rope between the second guide member and the first guide member is a drawstring end, and the later rope of the first guide member is a free end. When it is necessary to descend, the operator does not lift the rope upwards, but pulls the rope at the end of the drawstring by hand. At this time, the rope at the end of the rope is changed from the tension state to the slack state, the human body begins to descend, and the free end rope Then it is mentioned.

According to a third aspect of the present invention, the first guide member is mounted on a side of the fixed plate, and the second guide member is mounted on a lower side of the fixed plate. According to a fourth aspect of the present invention, the guide member is a roller assembly, the roller assembly is fixed to the fixed plate, and the roller assembly has a rotating guide wheel. When the rope at the end of the drawstring is pulled down, the working rope drives the guide wheel in the roller assembly to rotate, and the rope at the end of the rope is changed from the tension state to the relaxed state, the human body begins to descend, and the free end rope is lifted upward.

The invention has the beneficial effects that by adding a guide rope member to change the running direction of the rope, when the operator needs to descend, instead of lifting the rope upward, the rope is pulled down, because when the operator is suspended in the air, whether it is adopted In the hanging position, or in the seat posture, pulling down the rope is better than pulling the rope upwards, which is not only easy to operate, but also safe and reliable. The hanging drop system proposed by the present invention is particularly suitable for training without suspension. The use of personnel, therefore, in addition to suitable for high-altitude suspension equipment for building exterior wall cleaning or exterior wall construction, can also be used as a fire escape equipment for buildings, or as a fire rescue equipment.
