Description

Buffer-braking anti-falling device for disposing rope breakage of vertical conveyor
Technical field
The present invention be more particularly directed to a kind of buffer-braking anti-falling device for disposing rope breakage of vertical conveyor.
Background technology
At present, the applied rope broken protector of vertical lift such as elevator machinery generally is to be made of velocity limiter and safety tongs.Its principle of work is to adopt friction braking, promptly stops it and moves downward when disconnected rope back velocity limiter drive safety tongs and guide rail generation friction force take place, and reaches to prevent the purpose of falling.Because behind the disconnected rope of elevator, the car get out of hand, approximate free-falling body moves downward, and its potential energy is transformed into kinetic energy with the acceleration/accel of nearly 9.8m/s.So, there are following three problems in friction braking: 1, according to conservation of energy theorem, its friction changes kinetic energy into heat energy, and the irony drg can produce high temperature, Gao Re and spark, the drg of other material can produce high temperature, high heat, and therefore inflammable and explosive place can not be used; 2, guide rail surface is smooth, and the end accident of squatting often takes place the friction braking distance; 3, braking energy is big, and drg and way rub are serious, the difficulty of resuming production.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists, provide a kind of and do not produce high heat of high temperature and spark, be suitable for all inflammable and explosive places uses, stopping distance is short, safe, the end accident of not squatting, sound construction, reliable operation, abrasive parts using not, the buffer-braking anti-falling device for disposing rope breakage of vertical conveyor that resumes production easily behind the rope-broken accident.
The present invention is achieved in that it comprises guide rail bracket, in guide rail bracket, be provided with car, its special character is: be provided with drg at the car internal upper part, described drg is to constitute by the brake beam that is fixed on the car internal upper part with by two brake rods that the brake axle symmetry is located at the brake beam both sides, be provided with disconnected rope inductor at car inner top surface center, described disconnected rope inductor is by induction rod, the inductor overcoat formation that is arranged on the pressing plate of induction rod lower end and is sleeved on the induction spring on the induction rod and is sleeved on induction spring outside, steel rope is drawn and be connected with in described induction rod upper end by the car end face, described pressing plate is sitting in the brake rod upper end, on brake beam, be positioned at disconnected rope inductor bilateral symmetry and be provided with energy disperser, described energy disperser lower end is laid with backstop near brake rod in the guide rail bracket inboard.
Above-mentioned buffer-braking anti-falling device for disposing rope breakage of vertical conveyor is provided with copper sheet at the backstop upper surface, to play explosion-proof.
Above-mentioned buffer-braking anti-falling device for disposing rope breakage of vertical conveyor, described energy disperser are to be made of buffer shaft and the recoil spring that is enclosed within on the buffer shaft, described buffer shaft upper end by the car end face draw, the lower end passes between two brake beams.
Above-mentioned buffer-braking anti-falling device for disposing rope breakage of vertical conveyor, described energy disperser are hydraulic damping device.
Above-mentioned buffer-braking anti-falling device for disposing rope breakage of vertical conveyor is set with the energy disperser overcoat in the outside of recoil spring, to play guiding and dustproof, rust inhibition.
Above-mentioned buffer-braking anti-falling device for disposing rope breakage of vertical conveyor, the place is provided with guide groove at the corresponding brake rod of pressing plate lower surface, to realize spacing to brake rod.
Above-mentioned buffer-braking anti-falling device for disposing rope breakage of vertical conveyor, corresponding energy disperser lower end is provided with guide groove on brake rod.
Advantage of the present invention is: owing to when disconnected rope, make the drg action by disconnected rope inductor, drg rotates gently and is stuck on the backstop under the buffer action of energy disperser.Therefore, this buffer-braking anti-falling device for disposing rope breakage of vertical conveyor glancing impact does not produce high temperature, Gao Re and spark, is suitable for all inflammable and explosive places and uses; Stopping distance is short, safe, the end accident of not squatting; Sound construction, reliable operation is convenient to management, and abrasive parts using does not resume production behind rope-broken accident easily.
