Abstract
The utility model discloses a falling-prevention safety device of an elevator and relates to an elevator assisting device. The falling-prevention safety device of the elevator can effectively ensure life safety of people in the elevator during falling. The falling-prevention safety device is provided with an air sac, an air nozzle, an air filling tube, an air sac fixing belt, a ratproof power grid, a metal ring, a fixing base and a monitoring tube. The air sac is arranged on the bottommost ground of an elevator mouth, one end of the air filling tube is connected with the air sac, and the other end of the air filling tube passes through a monitoring tube of the air nozzle; an air pressure meter is arranged on the monitoring tube; one end of the air sac fixing belt is connected with the air sac, and the other end of the air sac fixing belt is arranged at the bottom of the air sac and fixed on the ground at the bottom of an elevator well; the ratproof power grid is arranged on the periphery of the air sac; the metal ring is arranged on the contact portion of the air sac and the ground, and the metal ring is connected with a high-frequency alternative current circuit; and the fixing base is arranged on the ground. The falling-prevention safety device is simple in structure, reliable in performance, low in manufacture cost, easy to produce and install, and good in damping effect, and can be used in civil elevators and lifts for construction.
Description
Technical field
The utility model relates to a kind of elevator auxiliary device, especially a kind of elevator anti-dropping safety device that adopts the air bag damping.
Background technology
Along with the development in city, skyscraper increases, and elevator has become the indispensable upper instrument downstairs of most of city dweller.And elevator is many, and the occurrence probability of accident also can raise naturally.Open motionless or do not open the glitch of door and so on if there is elevator, repairing, can also continue to use, can not hurt the people's that takes a lift life security; But just in case the accident of steel rope or the unexpected fracture of connecting device or out of control or brake failure and so on occurs, that problem is just large.The lighter hurts sb.'s feelings, and the severe one ladder is ruined the people and died, and directly injures people's lives and properties.
Existing elevator elevator born instant out of control namely occurs when encountering above-mentioned serious accident, is to absorb the downward impulsive force of elevator by being arranged on ground 4 springs, thus the assurance person's of taking a lift safety.And only depend on 4 springs to come damping, be nowhere near.Because spring is little, hold the impulsive force of weight that can't stand whole elevator and people, if being strengthened, spring changes slightly, the too fast buffering course that do not have that slows down also just can not play the actv. damping.Due to the restriction that is subject to the spring proper property, the impulsive force when the damping stage clip can not fully sponge the pendant ladder reach buffer action, so the elevator event of hurting sb.'s feelings happens occasionally.Although the pendant ladder is uncommon with the air crash accident, can in case generation just has ladder to ruin the serious accident that the people dies.
Summary of the invention
The utility model all provide a kind of when elevator when the pendant ladder occurring, can effectively guarantee the elevator anti-dropping safety device of the person's of taking a lift life security.
The utility model is provided with air bag, tire tube valve, appendix, air bag clamping band, protection against rodents electrical network, wire loop, permanent seat and monitoring pipe; Described air bag is located on the bottommost ground of elevator shaft mouth, and an end of appendix is connected with air bag, and the other end of appendix connects the monitoring pipe through tire tube valve; The monitoring pipe is provided with air-pressure gauge; One end of air bag clamping band is connected with air bag, and the other end of air bag clamping band is located at the air bag bottom and is fixed on the ground of elevator shaft bottom; Described protection against rodents electrical network is located at the air bag periphery; Described wire loop is located at air bag and contact position, ground, and wire loop connects high frequency ac circuit; Described permanent seat is located at ground.
Can be provided with the buffering exhaust hole on described air bag, described buffering exhaust posts plastic nylon cloth on the hole.
Obviously, compare with existing damping spring, the utility model is more than using spring shock absorption effective, and to slow down be near progressively slowing down slowly, effectively extends buffering course, and is minimum to the impulsive force that human body produces.So, it is arranged on ground under elevator, ideal.Its performance simple in structure is reliable, and cost is low, production is installed easily, is a kind of effect shock absorption device preferably.The utility model also can be used on the construction elevator except can be used on civilian elevator.
Description of drawings
Fig. 1 is that the surface structure of the utility model embodiment forms schematic diagram.
Fig. 2 is the installation site schematic diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the utility model embodiment is provided with air bag 1, tire tube valve 2, appendix 3, air bag clamping band 4, protection against rodents electrical network 5, wire loop 6, permanent seat 7 and monitoring pipe 9; Described air bag 1 is located on the bottommost ground of elevator shaft mouth, and an end of appendix 3 is connected with air bag 1, and the other end of appendix 3 connects monitoring pipe 9 through tire tube valve 2; Monitoring pipe 9 is provided with air-pressure gauge 10; One end of air bag clamping band 4 is connected with air bag 1, and the other end of air bag clamping band 4 is located at air bag 1 bottom and is fixed on the ground of elevator shaft bottom; Described protection against rodents electrical network 5 is located at air bag 1 periphery; Described wire loop 6 is located at air bag 1 and contact position, ground, and wire loop 6 connects high frequency ac circuit; Described permanent seat 7 is located at ground.
Can be provided with buffering exhaust hole 8 on described air bag 1, post plastic nylon cloth on described buffering exhaust hole 8.
Air bag clamping band 4 is located at air bag 1 below, and is provided with fixed orifice at the clamping band end, in order to air bag is fixed on the ground.Air-pressure gauge and under-voltage acousto-optic hint circuit are located at the position that service personnel is easily observed, and the personnel of maintaining easily observe air pressure, and remind the service personnel qi of chong channel ascending adversely or search disappointing reason when under-voltage.For reducing elevator after tenesmus bumps against air bag, prevent that the air bag bounce-back from must extend buffer distance, improves damping effect.Specially in the airbag wall surrounding, a plurality of small de-air hole are set, deflation hole by covering than thin plastic nylon cloth than air bag, makes air bag still keep normal barometric pressure at ordinary times.And when being clashed into, when air pressure is given birth to certain value, break through the plastic nylon cloth that is attached on deflation hole, and discharge appropriate air, make the elevator can be in limited space, the prolonged deceleration distance reaches best shockproof effect.In addition, can prevent that also air bag from being clashed into moment, can not make because pressure is excessive balloon rupture.For preventing the mouse air bag of breaking by the teeth, specially establish a conductive metal gauze of circle at the air bag place of being engaged with ground more, logical upper high-frequency currents makes the mouse dare not be near guaranteeing that damaged gas leakage can not appear in the permanent use of air bag.
Impact is too quickly in order to prevent from clashing into makes balloon rupture and improves damping effect, special a plurality of deflation holes is set around airbag wall, and deflation hole is covered by plastic nylon cloth at ordinary times, only when being clashed into, and when air pressure arrives certain pressure, could be as outer exhaust.
As shown in Figure 2, the utility model air bag 1 is the ground that is installed in the bottommost of elevator shaft mouth.During installation, the top of air bag 1 can not exceed the ground under elevator door.Make elevator when normal operation, elevator is encountered air bag 1 never.
