Description
One, technical field
The present invention relates to a kind of check band formula anti-fall device, be particularly useful for the lifting of vertical shaft for mine.
Two, background technology
Lifting means is an important step in the mine production system, in order to guarantee to produce and personnel's safety, " safety regulations in coal mine " the 383rd regulation " the single-rope hoisting cage of lifting personnel or lifting personnel and material, carry the skip bucket in the human world, must installing failure-free falling protector ".The falling protector that has used generally has three kinds, and a kind of is the wooden cage guide falling protector, and a kind of is the rail falling protector, and another kind is the check band falling protector.The check band falling protector has many good qualities with respect to preceding two kinds: small investment, easy for installation, therefore performance is also reliable than the above two, in the single wire winding type elevator system, obtains more use.Widely used anti-fall safety device mainly contains falling protectors such as GS type, FS type and BF type at present.The patent No. is that to be a kind of four eyed connecting strap that is contained in tank deck and spring strut embrace the falling protector that check band is braked by the moving iron of stopping of sliding of transmission hook strip with 90211600.2 disclosed falling protectors; The patent No. is that 96213454.6 disclosed small-sized falling protectors are a kind of falling protectors that utilize the damping of spring oil pressure as energy disperser; The patent No. is that 97222865.9 disclosed small-sized mining parachutes are that a kind of former cage guide rope of utilizing that is suitable for using on the little tonnage lifting means of small-size coal mine is made the falling protector of check band; The patent No. is that 97247977.5 disclosed local mine parachute gears are a kind of falling protectors that utilize eccentric wheel to clamp check band from wedging; The patent No. is that the 98215964.1 disclosed mining braking shock absorbers of arresting are a kind of falling protectors that a cover inhibiting device cushions that are provided with on catching device; The patent No. is that 98247696.5 disclosed mining falling protectors are that a kind of pressure of the spring generation that is provided with on the main tie that utilizes is stirred chock by two push rods, clamps the falling protector that cage guide rope is finished the buffer-braking action by deciding piece and chock; The patent No. is that the anti-fall catching device of 00221720.1 disclosed a kind of rail skip bucket is a kind of falling protector that utilizes the force of cut of many group sawtooth on the voussoir as anti-fall braking force.Though above-mentioned falling protector has all improved the safety condition of shaft hoisting, their main differences are the difference of arresting agency.The check band falling protector generally is made up of energy disperser, snub rope, adaptor union, check band, catching device and shaft bottom take-up device etc.What the present great majority of energy disperser adopted is steel rope spiral energy disperser, because the sort buffer device is to cushion by the flexural deformation and the friction force of snub rope in energy disperser, for guaranteeing to have enough buffering resistances, must there be bigger flexural deformation the snub rope by energy disperser the time, this certainly will damage buffer rope, reduce its initial strength, thereby when selecting buffer rope, require its initial strength will be much higher than brake wire, and its brake resistance is difficult to accurate Calculation, causes brake resistance and deceleration/decel more much bigger than what estimate.The snub rope adopts the above steel rope of 43mm substantially at present, deviate from from energy disperser in order to prevent the glancing impact snub rope, the end of buffer rope must pour into cone-shaped with Babbitt matal (tin-base bearing metal), little circular shaft, slide block in disconnected in addition rope snub rope, back and the energy disperser are subjected to great wearing and tearing, must change, increase the processing time after the accident.Adaptor union has single rope formula adaptor union, three rope formula adaptor unions and pulley-type adaptor union or the like, the general list rope pin type Babbitt matal cast adaptor union that adopts on the colliery, this adaptor union is installed inconvenient, because need cast, all must change adaptor union when each exchange buffering rope or check band, so increased labour intensity, prolonged the replacing time, make troubles for on-the-spot the use.Catching device generally all adopts extension spring mechanism, and its drawback is that the working pulling force of extension spring is unadjustable, and the size of working pulling force has directly determined the reliability of its arresting agency, so brought hidden danger to safety in production.
Three, technology contents
1. goal of the invention
Deficiency in view of prior art exists the purpose of this invention is to provide a kind of replacing easy for installation, quick, a kind of check band formula of deceleration and stopping performance failure-free anti-fall device.
2. technical scheme
