Abstract
The utility model discloses an emergency rescue device for a machine-roomless elevator, which comprises a jack stand (1). Both ends of the jack stand (1) are provided with guide rail pressure plate racks (2); a top plate (3) is arranged on the jack stand (1) and connected with a bottom plate (4) by screws and nuts; a jack (5) is arranged between the bottom plate (4) and the top plate (3); a guide rod (6) is arranged on the bottom plate (4); the guide rod (6) passes through the top plate (3) and is connected with a compensating chain fixing plywood (7); the compensating chain fixing plywood (7) is provided with a U-shaped screw (8) which is connected with one end of a thread fastener (9); and the other end of the thread fastener (9) is provided with a S-shaped hook (10). The emergency rescue device changes the current situation that no rescue equipment exists when machine-roomless elevator cannot move under a power failure condition as the descending safety clamp clamps the steel wire rope car, thereby preventing accidents from being enlarged.
Description
Technical field
The utility model relates to the urgent help-seeking device of a kind of elevator help-seeking device, particularly a kind of machine-roomless lift.
Background technology
Along with skyscraper is more and more, the application of elevator also very extensively.In order to guarantee the safety of elevator operation, design has descending safety tongs in the control system of elevator, surpasses certain speed when elevator is descending, and descending safety tongs will be clamped the steel rope that hauls cab, prevents that cab from falling, and has an accident.At this moment as long as by system up button cashier's office in a shop, allow car more up by force, descending safety tongs will unclamp automatically, removes the clamping to the cab steel rope.If just run into power failure this moment, cab just can not have been moved so.People in the cab can't get out, and can feeling at heart of people is very panic, suddenly makes an uproar, and also can have an accident sometimes.For the elevator device that machine room is arranged, generally dispose jigger wheel, can twist steel rope by jigger wheel, make cab more up, descending safety tongs is unclamped automatically, but, jigger wheel is not set for the elevator device of no machine room, run into above-mentioned situation and just be difficult to solve.
The utility model content
The purpose of this utility model is, a kind of urgent help-seeking device of machine-roomless lift is provided, and solves machine-roomless lift and clamps the steel rope cab when active at power down mode because of descending safety tongs, and the present situation of no wrecking equipment can prevent accident expansion.
The technical solution of the utility model: a kind of urgent help-seeking device of machine-roomless lift, comprise jack stand, the jack stand two ends are provided with the guide rail clip frame; Jack stand is provided with top board, and top board is connected with base plate with nut through screw rod; Between base plate and top board, be provided with jack; Also be provided with guide rod on base plate, guide rod passes top board and is connected with the compensated chain strap; The compensated chain strap is provided with the U-shaped screw rod, and the U-shaped screw rod is connected with screw buckle one end, and the screw buckle other end is provided with the hook of S shape.
In the urgent help-seeking device of above-mentioned machine-roomless lift, described jack is fixed on the base plate through pressing plate.
Compared with prior art, prior art does not have machine-roomless lift to clamp the steel rope cab when active at power down mode because of descending safety tongs, the device that the cab personnel are rescued, the utility model can solve machine-roomless lift and clamp the steel rope cab when active at power down mode because of descending safety tongs, and personnel rescue to cab.Alleviate the Psychological Panic that is trapped in the people in the cab, urgency is made an uproar and mood prevents that accident from further enlarging.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to view.
Being labeled as among the figure: 1-jack stand, 2-guide rail clip frame, 3-top board, 4-base plate, 5-jack, 6-guide rod, 7-compensated chain strap, 8-U shape screw rod, 9-screw buckle, the hook of 10-S shape, 11-pressing plate, 12-weight guide, the compensated chain of 13-counterweight side.
The specific embodiment
Be described in further detail below in conjunction with the urgent help-seeking device of drawings and Examples a kind of machine-roomless lift of the present utility model, but not as the foundation of the utility model being done any restriction.
Embodiment.The urgent help-seeking device of a kind of machine-roomless lift of the present utility model, as shown in Figure 1.Comprise jack stand 1, jack stand 1 two ends are provided with guide rail clip frame 2; Jack stand 1 is provided with top board 3, and top board 3 is connected with base plate 4 with nut through screw rod; Between base plate 4 and top board 3, be provided with jack 5; Jack 5 is fixed on the base plate 4 through pressing plate 11.Also be provided with guide rod 6 on base plate 4, guide rod 6 passes top board 3 and is connected with compensated chain strap 7; Compensated chain strap 7 is provided with U-shaped screw rod 8, and U-shaped screw rod 8 is connected with screw buckle 9 one ends, and screw buckle 9 other ends are provided with S shape hook 10.
Working process of the present utility model and principle: the utility model is when implementing rescue, earlier the guide rail clip frame 2 at jack stand 1 two ends is connected with weight guide 12 on the elevator and fixes tightly, then turnbuckle on the utility model 9 is caught on the compensated chain 13 of counterweight side on the elevator through S shape hook 10, utilize 9 of turnbuckles to draw very with elevator bonded assembly steel rope.At this moment, a maintainer utilizes main frame machinery to declutch main frame is declutched to the control housing place; Another maintainer enters pit operation jack 5, when the push rod of jack 5 rises, distance between top board 3 and the base plate 4 is widened, base plate 4 is being with compensated chain strap 7 to move down by guide rod 6, compensated chain strap 7 is left behind the compensated chain 13 of counterweight side through U-shaped screw rod 8, screw buckle 9 and S shape hook 10, when the compensated chain 13 of counterweight side pulled down, the car of elevator must be up, unclamps automatically thereby make descending safety tongs reset; After safety tongs resets, unclamp the steel rope that clamping.At this moment elevator cage is hauled by the utility model, can only be up, and can not be descending.Can be directly with manually drawing counterweight side compensated chain 13 or relying on the overbalance of counterweight car both sides weight to make car slowly up; When car moves to the flat bed zone, the device that declutches of the maintainer's Shutdown Hosts machinery at the control housing place, and notify other maintainers to open layer door and implement rescue.
