Abstract

The utility model relates to the technical field of elevators, and discloses an elevator without a winch. The elevator comprises a pulley, a steel wire rope, cars, a water pipe, water tanks, a water pump and hoistways where the cars can operate. The elevator without the winch is characterized in that the bottom part of each car contacts with each hoistway in the sealing way; an opening is formed on the upper end of each hoistway; four walls and the bottom part of each hoistway are sealed; a small air exhaust hole, a unidirectional valve and a hoistway gate for one person are arranged on the bottom part of each hoistway. When the manned car lifts, water at the water tank at one side is pumped to the opposite water tank so that the car at the opposite side falls due to large weight; the gas in the hoistway of the opposite side is compressed; the unidirectional valve is closed; the gas exhaust hole exhausts the gas; the car at the opposite side slowly falls to the bottom part of the hoistway according to the resistance effect of the gas; and the manned car lifts the upper floor. Persons can conveniently go upstairs and downstairs, the footbridge or upwards and downwards carry the cargos by the elevator without the winch disclosed by the utility model; the elevator without the winch has safe operation and does not need the winch, a machine room and the like; and the elevator without the winch has the advantages of simple structure, low cost, saved energy and wide use.

Among the figure, 1. pulley, 2. steel rope, 3. water tank, 4. sedan-chair case, 5. above floor, a 6. road, 7. water pump, 8. water pipe, 9. below floor, 10. one-way cock, 11. bleeder ports, 12. sects.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.

The companion ladder of the described no winch of the utility model, as depicted in figs. 1 and 2, comprise the pulley 1 that is fixed on the building body; Hang over the steel rope 2 on the pulley 1, steel rope 2 ends connect sedan-chair case 4, and the water tank 3 of individual water is arranged at sedan-chair case 4 tops; Its interior vertical tube road 6 of sedan-chair case operation, tube road 6 open upper end, wall and bottom are airtight all around; Tube 6 bottoms, road have a little bleeder port 11, change hole size scalable sedan-chair case descending speed, and tube 6 bottoms, road have an one-way cock 10; One-way cock 10 is closed when the sedan-chair case descends, and seals gas; When the sedan-chair case rises, open, suck a large amount of gases.Tube 6 bottoms, road have the tube sect 12 of people's turnover, and open in 6 inboards, tube road at tube sect 12, when the sedan-chair case descends bottom, tube road, and sedan-chair case bottom compression spring, open automatically at tube sect 12; When the sedan-chair case left bottom, a tin road, spring promoted a tube sect and closes, and it is air tight to close the back.Sedan-chair case 4 bottoms and tube road 6 airtight contacts, air tight or micro-leakage body, hook is arranged at sedan-chair case 4 tops; The sedan-chair case is raised to top, tangles the not rise and fall of sedan-chair case, and the people clicks the hook button in inside; The sedan-chair case can descend because of gravity; Water tank 3 connects water pipe 8, and water pipe 8 connects water pump 7, and water pump 7 is connected with the mains.

The companion ladder of the described no winch of the utility model; Utilized people and object itself just to have certain potential energy aloft; Just no longer need consume extra power to lower down; As long as with the water tank in the water suction decline sedan-chair case in the rising sedan-chair case, when rising sedan-chair case gross weight during less than decline sedan-chair case, rising sedan-chair case will begin to rise; Utilize the confined air vapour lock to end the sedan-chair case and descend, utilize little bleeder port to control sedan-chair case descending speed, with reach people and object under the eminence safety to the purpose of lower.

During use; At first people get into sedan-chair case 4 from following floor 9, when confirming to go upstairs, click the rising button; Make hook disengagement buildings on the opposite side sedan-chair case 4 through electric energy; Water pump 7 begins to draw water and injects the water tank 3 of opposite side sedan-chair case 4, and opposite side sedan-chair case 4 can descend because of gravity a little while, and this limit sedan-chair case 4 rises; When opposite side sedan-chair case 4 descended, gas was compressed in the tube road 6, and one-way cock 10 is closed, and gas pressure intensity increases in the tube road 6, stoped opposite side sedan-chair case 4 to descend, and under the situation of bleeder port exhaust, opposite side sedan-chair case 4 slowly at the uniform velocity descends.This limit sedan-chair case 4 receives pulling force and rises, and its side neck sect 12 is closed under the spring force effect, and one-way cock 10 is opened, and sucks a large amount of gases.When opposite side sedan-chair case arrives tube 6 bottoms, road for 4 times, opposite side sedan-chair case 4 bottom compression springs, open automatically at a tube sect 12; People can get into or leave a road 6.This limit sedan-chair case 4 has been raised to top floor, and hook hook under the spring force effect lives buildings, and two sedan-chair casees 4 are no longer motion all, up to there being the people in upper strata sedan-chair case 4, to press start button.

Surface phenomena is during use: in the time of upstairs, below the floor people get into the sedan-chair case, click start button, water pump begins to draw water, after several seconds, the sedan-chair case begins to rise, and speeds up, after several seconds, water pump quits work, the sedan-chair case at the uniform velocity rises to top floor; In the time of downstairs, above the floor people get into the sedan-chair case, click start button, water pump begins to draw water, after several seconds, the sedan-chair case begins to descend, and speeds up, after several seconds, water pump quits work, the sedan-chair case at the uniform velocity drops to following floor.

Above-mentioned embodiment is an instance of the utility model; Not enforcement and the interest field that is used for limiting utility model; All equivalences of making according to the described content of the utility model patent protection scope change and modify, and all should be included in the utility model patent protection scope.
