Problems solved by technology
[0002] Most of the life-saving descending devices that appear at present are small reciprocating descending devices that can be used by individuals. This kind of descending device has its flexibility, but it is not suitable for many people to use, and its efficiency is low. In addition, a large-scale descending device that has recently appeared The life-saving equipment can be used by multiple people, and its efficiency is high, but its operation is very complicated, requiring people on the ground and in the equipment at the same time, and the cost is high

Embodiment Construction
[0027] The structure and principle of the present invention will be further described below in conjunction with the accompanying drawings. figure 1 It is a side view of the main structure of the present invention, figure 2 It is the front view of the present invention. This new type of use is mainly composed of retractable track mechanism I, slow down mechanism II, screw nut transmission mechanism III, support frame IV, chain transmission mechanism V and recovery mechanism VI.
[0028] The support frame IV of the slow-down device is a steel structure, which is required to be sturdy and durable. Its shape is like a corridor, with closed sides, and the passage can be entered and operated. The top is a movable slow-down mechanism II. To move it, the screw nut transmission mechanism is connected with the chain transmission mechanism V at the rear and controlled by the handwheel. This bracing frame middle part stretches out two beams, and movable retractable track mechanism 1 i...

The invention provides a medium-sized uniform-speed escape descent control device which can be used by multiple persons. The descent control device mainly comprises a retractable track mechanism, a planetary wheel air resistance descent control mechanism, a lead screw nut transmission mechanism, a support frame and a chain transmission mechanism, wherein a movable descent control mechanism and a movable track rope pulley are arranged on a steel structure support frame; and the descent control mechanism is ejected by swinging the chain transmission mechanism through a hand wheel, the track is put down by swinging a hand wheel of the retractable track mechanism, and escape personnel descends along with a descending steel wire rope after buckling a safety suspension loop of the descent control rope. The device is used for controlling descent by using the planetary wheel air resistance descent control mechanism. The descent control device has the characteristics of easiness for operating, stable descending speed, small occupied area, simple and practical structure, safety and reliability.
Description
technical field [0001] The invention provides a medium-sized reciprocating life-saving descending device that can be used by multiple people, is simple to operate, safe and reliable, and belongs to the technical field of high-rise life-saving devices. Background technique [0002] Most of the life-saving descending devices that appear at present are small reciprocating descending devices that can be used by individuals. This kind of descending device has its flexibility, but it is not suitable for many people to use, and its efficiency is low. In addition, a large-scale descending device that has recently appeared High-quality life-saving equipment can be used by multiple people, and its efficiency is relatively high, but its operation is very complicated, requiring people on the ground and in the equipment at the same time, and the cost is high. In view of the shortcomings of various slow-down devices above, the present invention has specially designed a kind of medium-size...
