Abstract
A vertical storage tank fixing safety belt device mainly comprises a detachable balance weight, a gear set with the fixed gear ratio, a brake and a protecting outer shell. A worker locks a safety belt and the body, the balance weight part has a pulling force effect during an upward-walking process, the effect of automatic steel wire rope contraction is achieved during a worker-ascending-resistance-reducing process, and the problem that a steel wire rope affects work during a worker-ascending process is avoided. If the worker falls off by accident, the brake is started automatically, a pawl locks gears, and worker falling off is avoided.
Description
Technical field
The present invention relates to fixedly seat belt apparatus of a kind of vertical storage tank, guaranteed upper tank work high above the ground personnel's safety.It is a kind of mechanical device.
Background technology
At present, only limit to be simple and easy to most the safety rope (band) of use on market, upper tank operating personnel ties up the waist operator one of safety rope (band) before upper tank, and other end is tied to and on tank spiral stairs, guarantees the safety of oneself.General storage tank is in order to guarantee the safety of winding staircase, (from the beginning safety rope can move tail to during design winding staircase handrail, not design through rod, without stopping), cause tank operating personnel often to walk the step that a segment distance just must re-execute " untie-lock " safety rope (band), very loaded down with trivial details and easily cause the security incidents such as personnel tumble, get injured by a fall.Up-to-date a kind of patented technology is the seat belt apparatus technology (patent No.: 201120253949), it is to consist of fastener, pulley and brake disc etc., needs operating personnel manually to control brake apparatus for storage tank.The present invention, by a kind of new thinking, is automatically controlled and carries out brake hard by device, has greatly improved security, has shortened brake reaction time, has guaranteed operating personnel's safety, and whole device is safer, more convenient.
Summary of the invention
The invention provides a kind of safety device, this safety device is responsible for automatically implementing brake hard when the emergencies such as surprisingly causing tumbling, falling appears in operating personnel, guarantees personnel's personal safety.This device free shrink arbitrarily under normal speed.Staff's this device in the process of ascending a height can provide pulling force upwards to them, helps that it is more laborsaving, carry out easily upper tank operation.
The technical solution adopted for the present invention to solve the technical problems is: whole safety belt combines by the gear train of one group of fixed gear ratio (gearratio is 1.5).Safety belt is connected with steel wire rope, is wound on spragging gear, forms in the lump brakes with centrifugal clutch.After gear wheel is meshing with pinion, be connected with counterweight part.When staff rises, counterweight provides auxiliary pulling force in automatic retractable safety rope, and help desk personnel is laborsaving; When occurring surprisingly causing falling, at this moment spragging gear rotates and accelerates, and centrifugal force throws away centrifugal trip(ping) lever and blocks ratchet, stops operating braked wheel is stuck.Meanwhile, braked wheel is because pulling force effect produces position skew, and the stuck shell ratchet of the gear teeth, provides double insurance, protection personal security.After pulling force disappears, because spring tension effect gear and centrifugal clutch are got back to original position, with ratchet disengaging, personnel can normal speed under tank.Main technical characterictic is 1, brake apparatus: speed is the activation power of brake apparatus.The core parts of this device are centrifugal clutches, and the critical component of centrifugal clutch is one and increases the weight of fork.When gear slow circumvolve, centrifugal clutch is because spring tension does not swing.But when wrench safety belt, braked wheel is by fast rotational, and centrifugal force makes centrifugal clutch outwards throw away stuck ratchet, forbid that gear rotates, protection staff.The invention has the beneficial effects as follows, after appearance is unexpected, carry out automatically and quickly brake hard.Meanwhile, provide rising auxiliary traction, structural safety, stable.
Accompanying drawing explanation
Fig. 1 is the fixedly structure chart of seat belt apparatus of a kind of vertical storage tank; Wherein 1 is shell, the 2nd, and spring, the 3rd, braked wheel, the 4th, ratchet, the 5th, auxiliary wheel, the 6th, steel wire rope, the 7th, safety belt, the 8th, weighted spherical ball, the 9th, weighted spherical ball installing hole
Fig. 2 is fixedly profile and the front elevation of seat belt apparatus of a kind of vertical storage tank; Wherein the 1, the 9th, shell, the 2nd, steel wire rope, the 3rd, safety belt, the 4th, ratchet, the 5th, pressing spring, the 6th, scroll spring, the 7th, spool, the 8th, draw spring.
Claims (5)
1. the fixing seat belt apparatus of a vertical storage tank, include (1) shell, (2) spring, (3) braked wheel (brake), (4) ratchet, (5) auxiliary wheel, (6) steel wire rope, (7) safety belt, (8) weighted spherical ball, (9) weighted spherical ball installing hole brake as claimed in claim 1, it is characterized in that following 2 1. described brake by centrifugal clutch, by core component, formed, when braked wheel rotates counterclockwise speed when excessive, centrifugal force throws away centrifugal trip(ping) lever and blocks ratchet, braked wheel is stuck, stop operating; 2. safety belt imposes on pulling force of braked wheel by steel wire rope, makes braked wheel position produce skew, and the gear teeth snap on braked wheel shell ratchet, and braked wheel is stuck, stop operating.
2. counterweight as claimed in claim 1, is characterized in that counterweight is connected with steel wire rope, and can scold and unload, and by gear train, power is passed to and on safety belt, plays two effects: first regains safety belt, prevents from affecting work; Second provides auxiliary traction power counterweight track shell as claimed in claim 1, it is characterized in that balancing weight to be all enclosed in housings, plays two effects: first prevents that counterweight from falling to causing people's injury; Second prevents from blowing makes balancing weight swing cause potential safety hazard.
3. spring as claimed in claim 1, when pulling force is excessive, makes the skew of braked wheel occurrence positions, and the gear teeth snap into stuck gear on shell ratchet; After pulling force disappears, spring retracts normal position by gear, departs from ratchet.
4. auxiliary wheel as claimed in claim 1, is characterized in that there is certain gear ratio (gearratio is 1.5) with braked wheel, because tank is high inconsistent with winding staircase length, prevents the upper situation that has dropped to ground to tank waist weighted spherical ball of people.
5. weighted spherical ball as claimed in claim 1, is characterized in that copper ball by 5 same weight forms a set of, can by (9) weighted spherical ball installing hole, freely remove and install according to actual service condition.
