Abstract
The invention is an elevator up-going clamping rope device installed between the tract wheel and guide wheel or right under the guide wheel. The steel wire crosses the device from the center. It is for the amendment of failures and safety assurance, includes steel wire clamping mechanism and trigger mechanism. The clamping mechanism has a fixed wedge and an active wedge symmetrically arranged in front and back side of the steel wire. The trigger mechanism consists of transient trigger, clasp board and the trigger pole fixed between and with the two clasp boards; the clasp board links with the active wedge hanging by active key, the trigger wire is fixed to the trigger pole, links to the elevator speed governor, is manually resettable by lift upwards slightly the pole after inserted into the hole previously made in the active wedge. The invention is of light trigger force, short trigger trip, adjustable brake force, many features such as tight structure, small size, light weight, easy to reset and so on. The clamp will become tighter and tighter when the elevator travels on inertia.
Description
Technical field
The present invention relates to the fault correction or the technical field of safety devices of elevator operation, especially relate to friction force and act on brake equipment on the car conductor rope.
Background technology
Prevent the mechanism that elevator overspeed is up at present, employing is arranged, make elevator entrainment machine out of service, with safety tongs guide rail is clamped again, make modes such as bridge case stop because of hypervelocity triggers the limiting device switch; These modes are because elevator operation inertia is big, and bridge case stop time expand exists unsafe hidden danger; For implementing overspeed protection, gradual braking, China's utility model patent discloses a kind of " brake for towline of elevator ", the patent No.: 01274866.8, the technical scheme of this patent is analogous to China's patent of invention disclosed a kind of " with the elevator car brake of spring driven brake shoes " publication number: CN1084482A, be by the moving liner plate of customization that is fixed on the riser, moving brake liner plate with the moving parallel making and settlement of liner plate of customization, the bearing pin that brake liner plate leads up and down will be moved, the link arm of two braking liner plate both sides is formed a clamping device, traction sheave is from passing between them, two link arms, one end and moving brake liner plate are hinged, the other end is hinged with the slide shaft that is through slip in the riser slotted hole, the energy stroage spring drawknot that slide shaft is fixed by the bottom, and be connected with trigger mechanism, reset by Bringing-back mechanism; Have characteristics such as simple in structure, that cost is low, overall dimensions are little; Shortcoming is that the required triggering power of pulling latch hook is bigger, clamps rope entirely by the spring force of energy stroage spring, with the positive pressure of parallel splint rope is clamped, and required Clamping force is also big.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned defective, provide a kind of when ascending for elevator exceeds the speed limit, under the triggering of speed monitoring device, can be with less triggering power, steel rope is clamped in realization, when continuing operation because of inertia, wire holder can press from both sides tighter and tighter, makes the rope brake for overspeed upgoing elevator of the up car deceleration stop of hypervelocity.
For achieving the above object, technical scheme of the present invention is such: a kind of rope brake for overspeed upgoing elevator, and be installed between elevator traction wheel and the track adjusting wheel or be installed under the track adjusting wheel, steel rope passes in the middle of wire holder; This wire holder has a frame, and this frame is by framework soleplate and be fixed in frame mainboard on the framework soleplate and upper, middle and lower framework lateral plate that frame backboard and the left and right sides are fixed between frame mainboard and the frame backboard constitutes; The Wedge-type steel rope is installed in frame clamps mechanism and trigger mechanism, said clamping mechanism has the movable voussoir that is symmetrically arranged in both sides before and after the steel rope, fixing voussoir, be fixed with liner plate on the movable voussoir, movable voussoir and fixedly be provided with ball row between the voussoir, on fixing voussoir, be fixed with movable voussoir and contacting the guide plate that connects, at movable voussoir with fixedly be fixed with extension spring between the voussoir; Fixedly voussoir links by a pair of dish spring pin and the frame mainboard of arranging up and down, and dish spring pin is provided with the dish spring, is provided with the stop pad on the frame mainboard; In fixing voussoir bottom by the bolt supporting that is located on the frame; Be fixed with the adjusting bolt in movable voussoir bottom; Said trigger mechanism has the hanger plate that fixes with the machine frame at two sides side plate respectively by set pin, and between two hanger plates and the frizzen that fixes with it; Hang connection activity voussoir by removable pin on the hanger plate, pilot bar is installed on the frizzen and triggers stay cord, the pilot bar other end is equipped with stage clip by the frame mainboard on the pilot bar, and stage clip is between frizzen and the frame mainboard; The triggering stay cord passes the frame mainboard and is external to elevator governor; Snap switch also is installed on the frame mainboard, and its contact can contact connection with frizzen.
Working process of the present invention is such: when the up hypervelocity of lift car reaches the responsiveness of velocity limiter, velocity limiter generation mechanical action moves to the snap switch direction by triggering stay cord drive frizzen, and frizzen can make the snap switch action earlier, cut off the electricity supply, make the towing machine stall; Hanger plate moves with frizzen removable pin is broken off relations simultaneously, and the movable voussoir while liner plate before and after lower slider makes in steel rope both sides is clamped steel rope.Because inertia makes the car of hypervelocity continue upward movement, promptly counterweight can continue to move downward, and traction steel-cable will continue to glide by drive activity voussoir like this, till the framework soleplate of the position, adjustable bolt top of movable voussoir.At this moment the butterfly spring voussoir that has been fixed has compressed a certain amount of, movable voussoir has produced enough positive pressures to steel rope, when steel rope continues to lower slider, make liner plate by special material on the movable voussoir steel rope is produced enough and the friction force steel rope reversing of motion, make the rapid stop of the counterweight that moves downward, that is to say to make up car deceleration stop.Fault is eliminated the back and is adopted hand reset, as long as with pole respectively in the default hole of insertion activity voussoir, carries and can reset on gently when resetting.
Owing to adopted technique scheme, a kind of rope brake for overspeed upgoing elevator of the present invention, required triggering power is little, required triggering stroke is short, and the liner plate of the movable voussoir of glancing impact and steel rope despatch wiping power are big, when continuing operation because of inertia, wire holder can press from both sides tighter and tighter, and do not damage steel rope, as long as the braking force adjustable size is the extension elongation of the adjustable bolt of adjustment activity voussoir bottom, stroke that can adjustment activity voussoir, change the amount of compression of dish spring, thereby reach the purpose of adjusting braking force, and have compact conformation, volume is little, in light weight, characteristics such as it is convenient to reset.
