Abstract
The invention discloses a cage-locking, cage-stabilizing and overwinding and overfalling brake device of a skip of a cage of a vertical shaft. The brake device consists of a brake oil cylinder (1), abrake plate and friction lining (2), a brake-releasing spring (3), a bearing pin (4), a supporting seat (5), a mounting beam (6), and a hydraulic servo system and electric control system (7). The brake device is characterized in that: the brake oil cylinder (1) is arranged on the supporting seat (5) by a pin shaft; the brake plate and friction lining (2), the brake-releasing spring (3) and the bearing pin(4) are arranged on the supporting seat(5); and the supporting seat (5) is in welding connection or bolted connection with the mounting beam (6). Due to the adoption of the structure of the bearing pin, the brake oil cylinder is not the directly operated type, and the braking force is not transferred to a piston, so that the oil leakage problem (the prior hydraulic disc type brake is the directly operated type, and the braking force is directly transferred to the piston.) is thoroughly solved. The operating principle of the brake device comprises that: when the cage stops at the mouthor bottom of a mine, the brake oil cylinder drives the brake plate and friction lining to clip the brake plate of the cage, so that the cage is stabilized by the friction force; and when the cage or skip is overwound or overfallen, the brake oil cylinder can clip the brake block in a mode of changing pressure, so that the cage or skip can be braked in the overwinding or overfalling range, and thebraking force meets the requirements of mine safety rules.

When cage chair is accepted cage, cage is in the suspention quiescence, when mine car or rubber-tired cart turnover cage, because the elastic deformation of hoisting cable causes play about the cage, cage chair is also followed cage play together, mine car slides down easily, and turnover side cage chair has great slope, mine car or rubber-tired cart turnover cage difficulty, it is very big particularly to work as well depth, or when the little but turnover cage vehicle weight of well depth was big, cage chair can not compensate the elastic telescopic amount of steel rope, thereby can not normally use.
Kinetic energy when self compensation holder jar cage chair utilizes the brute spring energy storage to absorb cage to fall jar.When cage normally fell jar with creeper speed, because this device has certain initial holder jar power, thereby flexibility was held cage; When cage fell at a high speed, cage can make claw overturn downwards, had so just avoided the generation of newly-risen sun jar accident.Self compensation holder jar cage chair has solved some shortcoming of common cage chair, but it is very big to work as well depth, or not very big at well depth, but transport vehicle and equipment weight is when very big, and the elasticity of steel rope shortened distortion when the elastic elongation distortion that steel rope caused when self compensation holder jar cage chair can only compensate transport vehicle and equipment and advances jar and can not separating had decided jar.
Conversion platform (external product) is German western mug(unit of measure) company, Sweden ABB AB product that some deep-wells of country are used in Germany, South Africa etc., and this device can be accepted cage and pin cage, but does not also use at home at present.Conversion platform is made up of steady jar of rocking arm, aligning gear, cushion cylinder etc.Its principle of work is when cage is parked in the shaft bottom, a steady jar rocking arm rides on the cage, there is aligning gear to put in the hole that cage reserves in steady jar of rocking arm, cushion cylinder is propped aligning gear can absorb the energy that the steel rope elastic deformation produces dynamically, and this system needs supporting complexity, expensive hydraulic efficiency servo could guarantee the reliability of work.
A kind of steady jar of mechanism and steady tank arrangement that is used for the vertical cage hoisting is to be invented by Nanjing Yougu Science and Technology Industrial Co., Ltd..This product principle is fully the same with conversion platform, does not also use at home.
Mistake at present commonly used licks and puts device and wedge guide, BS type multi-disc type friction pulleying are arranged, cross and put device, HZSN shaped steel belt overwinding-proof, cross and put device in the vertical cage hoisting.
The wedge guide braking force is less, and braking force is that the tapering along with wedge guide increases low price gradually.But braking distance is bigger, and pulleying, mistake are put the bad recovery of back container.This form of the many employings of the old mine of past design-calculated.
BS type multi-disc type friction pulleying is the product that China Mining University's invention is made, and mainly is to utilize multi-disc type friction braking principle to absorb pulleying, cross the kinetic energy of putting container.Its characteristics: simple in structure, braking force is stablized.Pulleying, cross and to put the back and recover simple, but braking force can not be regulated.
HZSN shaped steel belt overwinding-proof, mistake are put the product that device is a Wuhan cloud bamboo scientific and technological development company.This device is to utilize roller pressing steel band to become the S type and absorb pulleying, cross the kinetic energy put, this product is to be produced by Germany western mug(unit of measure) company abroad, is domesticly utilized the endergonic overwinding-proof of strip deformation, is crossed and put device by professor Sun Yurong of China Mining University invention as far back as 1992.The energy of this kind device steel band plastic deformation can not accurately calculate, and mainly determines by the method for experiment.
In sum, propping up a jar machine, cage chair, self compensation holder jar cage chair promotes or heavy equipment is restricted when promoting at deep-well; The conversion platform device is an external product, and expense is introduced in advance up to about 2,000 ten thousand Renminbi in domestic certain ore deposit.A kind of steady jar of mechanism and steady tank arrangement that is used for the vertical cage hoisting also only applied for patent of invention, the example that does not have product to use.Existing overwinding-proof, cross and put device various shortcomings are more or less arranged, therefore need these problems that a kind of new product solves appearance.
