Elevator passengers stranded after power down the device operational car
The default mechanism in the body of the car fled the floor to do active devices,[link widoczny dla zalogowanych], the technology of mechanical structures. 2 Background Art At present, the lift operating around the world, the prevalence of such elevators due to power failure or malfunction caused the fire crew trapped in the car phenomenon in such a situation occur, it is often the scene by the elevator maintenance mechanic to the implementation of poverty. The event of a fire or terrorist attack, trapped in the passenger than the car in a completely passive and can not save themselves embarrassment, it is necessary to design a passive device to solve this situation in order to increase the security of people take the elevator. 3 Invention of the technical solution of the utility model are: the top of the original car, set up as an area the size of the car top pulley bracket, so that the stent to change the traction rope and inseparable relationship between the original car, through the stent wire connection with the car, forming an indirect whole. Pulley bracket is designed to be: in the pulley bracket in 48IjEleVat. rVbl15N. 19. ct2. . 4 to set up a counter-top sheave, the traction rope to the original in this anti-sheave wear, in the top left and right pulley bracket, each set of two Vice-pulley, to form a rope can not be separated from the traction WHEELS. In the car's floor, set the left and right groups gathered rope drum, drum collected two sets of specifications of steel wire rope, like,[link widoczny dla zalogowanych], symmetrical horizontally, about two axes in the middle of the same size each set up a worm wheel connected with the host into a whole, so that the two gear wheels, and drums can be divided into two groups to collect 4 sets rope area, between the two worm gear, set up a worm perpendicular to the car floor, worm and worm gear about the same time the two axes of the two meshing, set up a worm at the top end of the disc with a hand wheel lock insurance, turning the hand wheel, worm and worm wheel is driven at the same time drive the two groups at the same time rotating drum rope to collect, store wire rope in the two groups on the collection drum 4 Strand Wire Rope 4 shares at the same time release the rope the same length, the left axis through the two strands, respectively,[link widoczny dla zalogowanych], under the left bottom corner of the car after the pulley, f'fi-the Zuoxiang upward through the wall to the left hand top of the two Vice-WHEELS pulley, the same time, the right axis, respectively, the two strands through the pulley on the right corner under the floor, along the right-hand wall has been up to the car through the right side of the top two vice pulleys WHEELS, 4 shares, respectively, through the wire rope rope WHEELS about l Yao Weidong After both sides of the four wheels, each wheel down to the bottom of the frame through which holes in the top of the beam fixed in the car bone. Both sides of the car for about 4 shares by the rope hanging in the pulley bracket 4 right and left,[link widoczny dla zalogowanych], vice pulley. When you turn the car floor under the hand of the worm wheel disc, set the rope drum 4 will be released at the same time share the same length of rope, the car will be under its own gravity to the release of half the distance down the length of rope, counter- the direction of handwheel, set to receive a short rope drum wire rope, pulley bracket until the bottom and top of the car until the parallel combination to form a whole. 4 a specific implementation plan or when a sudden power failure the elevator car to stop the operation of a fire caused when the car is not conducive to most of the crew will be parked in and out of the wells, the installation of this utility model of car, you can operate from the trapped crew floor under the car down to safety, coupled with the failure of existing door opening technology,[link widoczny dla zalogowanych], the crew compartment can be opened at the car door and landing door failure to implement initiatives predicament, without affecting the original performance and appearance of the elevator under the premise more than an active means of escape from disaster floors.
