Description

A kind of elevator of gravity drive

Technical field

The present invention relates to a kind of elevator with gravity drive.

Background technology

Existing elevator is based on driven by power, the energy consumption high cost is expensive, (annotate: China Patent No. 200720052673.7) also have critical defect: two water tanks of hanging lift lifting/lowering (being the beneath reserve tank of gravity tank and car) respectively are set with the technical scheme of gravity drive individually, two water tanks respectively are with a water pump, there is sebific duct to connect between the water tank, by pump water realization gravity allotment back and forth between the water tank that moves up and down respectively at two, this scheme defective is, will cause discharge little if the sebific duct caliber is little, pump water time expand, prolong cycle of run, the big more cycle of run of load-carrying is long more, so the little frequency and the load carrying ability that will limit the long-term use elevator of caliber; If but strengthen the sebific duct caliber, the weight (sebific duct and water pump need with the water tank lifting) that will increase the interior water of sebific duct and pipe and increase water pump, add the weight that will promote water tank, increased greatly and promoted load and electric energy consumption, the hoisting depth and the load carrying ability of elevator have also been limited, therefore this scheme has open defect, and is infeasible.

Summary of the invention

In order to solve above-mentioned elevator because of two defectives of causing of the contradiction of the water tank water pump of hanging lift lifting/lowering and lifting load that sebific duct brings and sebific duct caliber respectively, the invention provides a kind of gravity drive elevator technology scheme that does not need mobile water tank, water pump and sebific duct, make gravity drive elevator energy-saving technical scheme become feasible.The present invention solves the problems of the technologies described above the technical scheme that is adopted: with the pond, car, bucket, the water pump branch is arranged, car and bucket are hung the two ends of hanging wirerope at, hang wirerope through three suspension pulleys that are fixed on well headroom, bucket and car can be done up and down relative to oppositely moving, two fixedly pond (deserve to be called pond and sink again or go up sink) are set respectively at the bottom of lifting hoistway and top up and down, two water pipes are arranged between the last sink, article one, be drain hose, another is a feed pipe, shutoff upper end, feed pipe lower end is communicated with upper pool, shutoff lower end, drain hose upper end is communicated with sink, individual water outlet is arranged at the bucket bottom, face toward on the position of drain hose with the water outlet of bucket bucket when stopping for every layer, drain hose all has a water inlet can accept the draining of bucket, on the close feed pipe relevant position of bucket bucket mouth when stopping for every layer, feed pipe all has a water outlet can be the bucket water filling, each water outlet all has electromagnetic valve, the switch of each electromagnetic valve all be provided with separately unrelated, regulate bucket gravity by supply barrel water filling draining, car is heavier than bucket, empty bucket can be drawn high, car is then with the gravity pull-up of bucket and water, sink has a little water pump and floating ball rod, the connecting rod middle part is fixed on the limit, pond with rotating shaft, water pump is stirred rocker switch control by floating ball rod, the ball float come-up makes connecting rod stir rocker switch startup water pump downwards when sink is expired soon, the pond water pump is delivered to upper pool, when Chi Shui drains soon, ball float decline makes connecting rod upwards stir rocker switch and switches off the pump, and visible water pump can move alone.

Four angles of car are provided with positioning catheter, there are three location wireropes and a spacer bar (being called for short three cables, one muscle) to pass positioning catheter respectively, three cables, one muscle upper end is fixed on the lifting well headroom, end, wirerope lower end, car location section is radial and trails, terminal anchor with the band spring is anchored at mattess, safety and steady when car is landed, spacer bar is implanted mattess.Establishing on the car munnion muscle of spacer bar brakes presss from both sides getting close to, the brake folder is fixed on the munnion muscle on one side, another side can be around the hinge folding, opening two ends of brake folder are worn a rope, can tighten up the folder mouth by straining this rope, the other end (be hinge end) relative with brake folder open end established a spring and will press from both sides and mouthful strut, and corresponding each layer stop place installs on spacer bar ◆ the shape elastic caoutchouc, by on brake folder and the spacer bar ◆ the collision of shape elastic caoutchouc realizes each layer stop.The invention has the beneficial effects as follows, the lifting load that existing gravity drive elevator brings because of mobile water tank water pump and sebific duct thereof and the contradiction of sebific duct caliber have been solved, realized that car utilizes the gravity drive of passenger or car when descending, car utilizes the gravity (drawing high) of bucket and water to drive when rising, realize efficient under gravity drive, energy-conservation, the running safely of elevator, met end carbon economic requirement.
