Description
Technical field
The utility model relates to a kind of hydraulic elevator, belongs to elevator and manufactures field.
Background technology
Hydraulic elevator relies on hydraulic-driven, and its advantage is that machine room arranges flexibly, does not need top layer machine room, and building requirement of strength is low, and building is not subject to vertical power, operation ride comfort, and apportioning valve can be realized infinite speed variation.But in common hydraulic efficiency pressure system, the leakage of hydraulic oil is that inevitably therefore the real-world operation speed of the delivery rate of hydraulic oil and car is nonsynchronous.In the situation that hydraulic efficiency pressure system has slight leakage, this is asynchronous is controlled, as the patent of patent CN101397112, discloses a kind of frequency-changing hydraulic elevator system, by the adjusting of fuel-feed system frequency also being compensated to the slight leakage of hydraulic oil.
But because the car of hydraulic elevator is directly fixing with hydraulic efficiency pressure system, once therefore sudden collapse appears in hydraulic efficiency pressure system, car can lose support within the extremely short time, causes potential safety hazard.
Utility model content
The utility model, for solving prior art problem, provides a kind of safe and reliable hydraulic elevator.
The technical solution of the utility model is: a kind of hydraulic elevator, comprise hoistway, be arranged at the car in described hoistway, and the hydraulic actuating cylinder that is arranged at described hoistway bottom and is fixedly connected with described car, the piston of described hydraulic actuating cylinder is fixedly connected with the bottom of described car by being flexibly connected piece, and the oil circuit entrance and exit of described hydraulic actuating cylinder is connected with feed apparatus by pressure sensitive device respectively; Described car is provided with for described car is interfixed with described hoistway or the relative brake equipment moving freely; Described flexible connection piece is connected with described pressure sensitive device respectively and is subject to the control of described pressure sensitive device with described brake equipment.
As preferably, described hoistway inwall is fixedly installed guide rail; Described car is arranged in described hoistway by described guide rail, and can move freely along described guide rail.
As preferably, described car is displaced on described guide rail by guide wheel, and described brake equipment comprises the friction part that can brake described guide wheel.
As preferably, described brake equipment also includes and can directly be supported in the support portion on described guide rail.
As preferably, described flexible connection piece comprises an axle drive shaft that is arranged at described car bottom and can rotates under the control of described pressure sensitive device, and is fixedly installed on the block on described axle drive shaft.
As preferably, the piston tip of described hydraulic actuating cylinder is provided with the fixture block matching with described block.
As preferably, described car bottom is also fixedly installed recoil spring, and described block and described fixture block are in the time of released state, and described block is butted on the lower end of described recoil spring.
As preferably, described car is also provided with speed detector, and described speed detector is connected with described brake equipment with described flexible connection piece and controls described flexible connection piece and the operation of described brake equipment.
Hydraulic elevator below traditional hydraulic actuating cylinder is arranged in car, when collapse suddenly appears in hydraulic efficiency pressure system, the piston of hydraulic actuating cylinder loses suddenly support, cause car to lose suddenly bearing force, therefore piston of the present utility model and car adopt detachable connection, and to the omnidistance monitoring of hydraulic efficiency pressure system, once between the entrance and exit of hydraulic efficiency pressure system there is the deviation of bigger numerical in oil liquid pressure, illustrate that more serious leakage appears in hydraulic efficiency pressure system, control system departs from car and hydraulic cylinder piston at once, car is stopped and is stopped in hoistway simultaneously, avoid the generation of further accident.Car is also provided with speed detector simultaneously, once the running velocity of car exceedes the design safety speed of elevator, control system also departs from car and hydraulic cylinder piston, car is stopped and is stopped in hoistway simultaneously.
In sum, the utility model can depart from time the connection between hydraulic actuating cylinder and car and stop and stop car, the safety misadventure of avoiding hydraulic system fault to bring.

Embodiment mono-:
A kind of hydraulic elevator, comprises hoistway 1, is arranged at the car 3 in hoistway 1, and the hydraulic actuating cylinder 5 that is arranged at hoistway 1 bottom and is fixedly connected with car 3, and hoistway 1 inwall is fixedly installed guide rail 2; Car 3 is displaced on guide rail 2 by guide wheel 4, and can move freely along guide rail 2.The piston 6 of hydraulic actuating cylinder 5 is fixedly connected with the bottom of car 3 by being flexibly connected piece, be flexibly connected piece and comprise an axle drive shaft 8 that is arranged at car 3 bottoms and can rotates under pressure sensitive device 12 is controlled, and being fixedly installed on the block 7 on axle drive shaft 8, piston 6 tops of hydraulic actuating cylinder 5 are provided with the fixture block 10 matching with block 7.Car 3 bottoms are also fixedly installed recoil spring 9, and block 7 is with fixture block 10 in the time of released state, and block 7 is butted on the lower end of recoil spring 9.The oil circuit entrance and exit of hydraulic actuating cylinder 5 is connected with feed apparatus 11 by pressure sensitive device 12 respectively; Car 3 is provided with for car 3 is interfixed with hoistway 1 or the relative brake equipment moving freely; Brake equipment comprises can be braked the friction part 13 of guide wheel 4 and can directly be supported in the support portion 14 on guide rail 2.Flexible connection piece is connected with pressure sensitive device 12 respectively with brake equipment and the induction installation 12 that is stressed is controlled.Car 3 is also provided with speed detector, and speed detector is connected with brake equipment with flexible connection piece and controls and is flexibly connected piece and brake equipment operation.
In the time that pressure sensitive device 12 senses that the oil liquid pressure gap of the entrance and exit of hydraulic actuating cylinder 5 becomes large, or speed detector senses when car 3 running velocitys exceed the maximum safe speed of elevator design, axle drive shaft 8 drives block 7 to rotate, discharge fixture block 10, piston 6 was thrown off from 3 ends of car, friction part 13 is stopped and is stopped guide wheel 4 simultaneously, and support portion 14 is butted on guide rail 2, and car 3 is fixed on guide rail 2.And piston 6 being thrown off from 3 ends of car when block 7, block 7 becomes car 3 bottom, now block 7 is butted on recoil spring 9, once car 3 falls, when block 7 directly contacts behind hoistway 1 bottom, recoil spring 9 can further cushion car 3, the rate of surviving while effectively promoting car 3 falling accident.
