Abstract
The utility model discloses a high-rise building escape device with the help of a long rope, which comprises the long rope, a hanging disc, an upper friction wheel, a lower friction wheel and a safety belt, wherein the upper friction wheel and the lower friction wheel are arranged on the hanging disc, the safety belt is connected onto a hanging ring arranged at the lower part of the hanging disc and is used for tying people, a tensioning wheel driven by a pretightening spring is arranged on the hanging disc arranged in the middle positions of the right sides of the upper friction wheel and the lower friction wheel, and the long rope extends towards the right side from the lower part of the upper friction wheel and the upper part of the lower friction wheel and is sheathed and wound the tensioning wheel. The utility model adopts the technical scheme that because the tensioning wheel driven by the pretightening spring is used for regulating the tensioning force of the long rope, the friction force between the friction wheels and the long rope can be automatically regulated according to the body weight of escapers, and the principle that the gravity of the escapers and the friction force are balanced is utilized, so high-rise building escapers can go down to the ground at a proper safe speed with the help of the long rope, the automatic regulation of the downwards sliding speed in the escaping downwards sliding process can be realized, the reliability is high, and the operation is easy.
Description
Technical field
The utility model relates to escape device, especially a kind of high-rise escape device by long rope.
Background technology
Existing high-rise escape device by long rope mainly contain machinery with two kinds of electromechanics, the high-rise escape device of machinery need utilize hand gear to regulate frictional force, the escape personnel is easy to generate wrong the manipulation under precarious position; Dynamo-electric its gyropilot complex structure of high-rise escape device, reliability is lower in the use.
The utility model content
The purpose of this utility model is: a kind of high-rise escape device by long rope simple, that reliability is high of handling is provided.
For achieving the above object, the utility model can be taked following technical proposals:
The utility model is by the high-rise escape device of long rope, comprise long rope, hanging scaffold, be arranged on last friction pulley and following friction pulley on the described hanging scaffold, and to be connected in being used on the suspension ring of described hanging scaffold bottom be people's safety belt, the hanging scaffold of friction pulley and middle part, following friction pulley right side is provided with the regulating wheel that is driven by preloading spring on described, and described long rope stretches to the right from the bottom of last friction pulley and the top of following friction pulley, and cover is around on the described regulating wheel.
Described regulating wheel comprises the flange mounting blocks that is fixed on the hanging scaffold, the protuberance of described flange mounting blocks is a rectangle, columniform sliding shoe middle part offer one with the suitable rectangle elongated slot of the protuberance of described flange mounting blocks, described preloading spring is installed in the described rectangle elongated slot on flange mounting blocks right side, and the external cylindrical surface of described sliding shoe and the inner headed face of pulley are slidingly matched; Be connected with two ratchet housings of rectangle at the front end of flange mounting blocks, be provided with spring in this pair ratchet housing, the two ends of this spring are symmetrically arranged with the upper and lower ratchet that can slide up and down in two ratchet housings, the upper end of described upward ratchet and the lower end of following ratchet are respectively equipped with upper and lower right helical teeth, and this upper and lower right helical teeth meshes with the left helical teeth of the last arc baffle plate lower end that is screwed onto the sliding shoe front end, the left helical teeth on the down arc baffle plate respectively.
The technical solution of the utility model, regulate the tensile force of long rope owing to adopted the regulating wheel that drives by preloading spring, can be according to survivor's body weight, automatically regulate the frictional force between friction pulley and the long rope, utilize survivor's gravity and frictional force principle for balance, make high-rise survivor drop to ground with suitable safety speed by long rope.The utility model is simple in structure, can be implemented in the automatic adjusting of gliding speed in the escape downslide process, and the reliability height is handled simple.
As further improvement, the utility model has adopted pawl structures, the upper end of described upward ratchet and the lower end of following ratchet are respectively equipped with upper and lower right helical teeth, this upper and lower right helical teeth meshes with the left helical teeth of the last arc baffle plate lower end that is screwed onto the sliding shoe front end, the left helical teeth on the down arc baffle plate respectively, when sliding shoe moved to right gradually, the right helical teeth on the ratchet was moving to right to their next tooth on the left helical teeth on the arc baffle plate.It is to the right that tension direction moves that this structure only allows regulating wheel, and regulating wheel moves to left (retreating) when preventing the bounce-back of length rope, has further improved reliability.
