Description
Technical Field
The utility model relates to a high-rise device of saving oneself especially relates to a pure mechanical type high-rise conflagration family formula is fleed and is saved oneself fast and fall device.
Background
With the continuous acceleration of the modernization process, the number of high-rise buildings is increased. Due to the limitation of fire-fighting facilities, once a high-rise building is in danger, particularly major accidents such as fire, earthquake and the like, the escape mode of people in the high-rise building is very important. At present, most of the escape devices for people on the market are fixed on a building body, and people are put down to the ground by a lifting device. Such devices are generally driven by a motor, and when danger occurs, the building is likely to be powered off, and once power supply is lost, the lifting device is extremely dangerous for falling personnel. Moreover, the lifting device has the limit of people to be placed at one time, so that the purpose of quick rescue is difficult to achieve, particularly, when a resident building has a fire hazard, one family cannot be rescued at the same time, and certain tragedies are easy to occur at emergency due to the fact that people pay all instincts for the family. Therefore, a device for rescuing a plurality of members in the whole family, which has a simple structure, is convenient to operate, and is safe and effective, is needed.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve above-mentioned technical problem, provide a device that is used for high-rise conflagration family to flee to save oneself.
A family of high-rise conflagration formula escape device that saves oneself, including casing, hawser and couple, the couple is fixed to be set up at hawser both ends. The shell comprises a box body and a box cover, and the box body is buckled with the box cover; the two ends of the shell are respectively provided with a cable outlet and a cable inlet, one side of one end of the shell is provided with a braking device, and the other side of the other end of the shell is provided with a safety hanging ring; two support tube clamping seats are fixedly arranged in the box cover in parallel; two supporting tubes are fixedly arranged at corresponding positions in the box body; the outer part of the braking device is a cylindrical cavity, a spring is arranged in the cylindrical cavity, a spring base is fixed at one end of the cylindrical cavity, and a push rod shaft is rotatably arranged at the other end of the cylindrical cavity; one end of the spring is fixed with the spring base, and the other end of the spring is fixedly provided with a pressure plate; a bird beak-shaped ejector rod is fixedly arranged in the middle of the ejector rod shaft, one end of the ejector rod shaft is provided with a brake arm, and the other end of the ejector rod shaft is provided with a brake handle; the tip end of the ejector rod is movably attached to the pressure plate; a heavy hammer pull rope is arranged at one end of the brake arm and fixed with the heavy hammer; a brake caliper rotating shaft is arranged on the wall of the cylindrical cavity in the vertical direction of the ejector rod shaft, a brake caliper is rotatably arranged on the brake caliper rotating shaft, one end of the brake caliper is a jaw, the other end of the brake caliper is a caliper arm, and the caliper arm is movably attached to the pressure plate; the cable passes through a cable outlet at the tail end of the shell, then passes through a jaw of the brake caliper, then winds a plurality of circles on the outer surfaces of the two supporting pipes according to an 8-shaped path, then passes through a cable inlet at the upper end of the shell, and finally is fixed on a balcony.
Further, the jaws of the brake caliper are staggered arc-shaped jaws.
Furthermore, a supporting arm is fixedly arranged on the outer surface of the wall body of the balcony.
Furthermore, the supporting arm can be folded and attached to the wall.
Furthermore, the cable is fixed on the supporting arm of the balcony.
The utility model discloses a theory of operation: (1) when in use, the rescued person A can hang the one end hook 1 of the utility model on the supporting arm 30 of the wall body, and the other end hook 1 passes through the balcony 3 and is thrown (or fixed) on the ground. The rescued person (taking the family as a unit) can pass the wearing safety rope through the safety hanging hole 15 to be fixed with the utility model. Then, the user jumps down over the balcony 3. During the falling process, the weight pulls the braking arm 1431 of the braking device 14 by its own weight, and the braking arm 1431 drives the mandril shaft 143 to rotate, so that the mandril 1430 arranged at the middle position of the mandril shaft 143 ejects the pressure plate 144 outwards. At this time, the spring 141 is pressed by the pressure plate 144 and contracts backwards, so that the pressing force applied by the spring 141 to the brake caliper 1450 disappears, the jaw 1451 of the brake caliper 1450 is in a loose state, the pressing force on the cable 2 in the jaw is lost, and the rescue device can descend smoothly.
(2) Because there is frictional force between hawser 2 and the stay tube 17 contact surface, the utility model discloses a with hawser 2 according to the mode of "8" font around establishing at the surface of two corresponding stay tubes 17 that set up to this increases hawser 2 and stay tube 17's area of contact, and then increases frictional force between the two. The gravity generated by the person or the heavy object is balanced or counteracted by the friction force generated between the two, so that the person or the heavy object falls at a constant speed or a small acceleration in the falling process.
(3) Because the weight is located at a certain distance below the rescued person, the weight can fall on the ground with the rescued person earlier, the fallen weight loses the effect of the weight pull rope 1433, the pulling force exerted by the weight on the brake arm 1431 disappears, the spring 141 ejects the holding pressure plate 144 again, at this time, the pressure plate 144 can start to contact with the clamp arm 1452 of the brake caliper 1450 arranged on the pressure plate 144, the clamp jaw 1451 is forced to be tightened, the cable 2 on the inner side of the pressure plate is extruded, the resultant force of the resistance exerted by the cable 2 due to the friction force of the outer wall of the support pipe 17 and the extrusion force of the clamp jaw 1451 exceeds the self weight of the whole system, a resistance force upwards along the cable 2 can be generated, and the resistance force the rescued person to be decelerated, so that the rescued person can. The deceleration control of the whole rescue device is controlled by the landing time of the weight, which is determined by the weight pull rope 1433 on the weight, and the longer the weight pull rope 1433 is, the earlier the weight lands, the earlier the braking effect will start. The length of the weight pull rope 1433 can be adjusted appropriately according to the physics common knowledge according to the actual situation, so as to achieve the rescue purpose better.
