Description
Technical field
The utility model relates to the technical field of elevator, especially a kind of hydraulic elevator.
Background technology
Elevator is power with electrical motor, and box like gondola is housed, and takes advantage of people or carrying goods for tier building, and vertical lift elevator has a car, operates between the vertical rigid guideway of at least two row.Mid-term in 19th century starts to occur hydraulic elevator, still applies on low-rise building so far.
But existing hydraulic elevator still comes with some shortcomings the very easy oil spilling of Hydraulic Pump of part, these hydraulic elevators on structure design, causes oil pressure unstable, and then cause the situation that operation exception instability appears in elevator.Meanwhile, due to hydraulic oil once overflow, the external environment easily polluted, and these hydraulic oil overflowed are once run into naked light, will cause fire accident, seriously injured the human safety issues of passenger.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provide a kind of hydraulic elevator of improvement, and oil pressure is steady, stable.
The utility model solves the technical scheme that its technical matters adopts: a kind of hydraulic elevator, comprises entablatrance arranged in parallel and cross sill, and the upper surface of described entablatrance is provided with car, and the upper surface of described cross sill is provided with hydraulic gear; The hydraulic reservoir that described hydraulic gear is comprised hydraulic ram and is connected by hydraulic oil pipe with hydraulic ram, the inside of described hydraulic ram is provided with hydraulic oil variable rod, described hydraulic oil variable rod upper and lower is provided with retracing spring, the top of hydraulic oil variable rod is provided with the rigidity plunger matched with hydraulic ram, the nearly top of hydraulic ram is provided with hydraulic oil overflow mouth, and the nearly top of described rigidity plunger offers admission port.
In order to reduce the rigidity friction of rigidity plunger to car, therefore the top of described rigidity plunger is provided with the rubber mount that can contact with car.
Further specifically, described hydraulic oil pipe is divided into Liang Tiao branch by a general branch, wherein a branch is provided with hydraulic valve, and an other branch is provided with hydraulic oil pump.
In order to avoid the out contaminated environment of the hydraulic oil overflow in hydraulic ram, simultaneously also in order to reduce the noise produced in Hydraulic Pump operational process, therefore the periphery of described hydraulic ram is coated with fire-proof sound insulation protective cover.
The beneficial effects of the utility model are: hydraulic elevator of the present utility model has the following advantages:
One, by arranging hydraulic oil variable rod in the inside of hydraulic ram, hydraulic oil variable rod upper and lower all arranges retracing spring, the nearly top of hydraulic ram arranges hydraulic oil overflow mouth, admission port is offered on the nearly top of rigidity plunger, make the oil pressure in hydraulic ram keep stable, and then improve the coefficient that operates steadily of elevator;
Two, by the coated fire-proof sound insulation protective cover in the periphery of hydraulic ram, once there is oil spilling phenomenon in hydraulic ram, fire-proof sound insulation protective cover can the hydraulic oil that overflows of splendid attire, effectively prevent hydraulic oil pollution external environment, stopped the generation of fire; Meanwhile, because the operation noise of hydraulic ram is very large, so the fire-proof sound insulation protective cover outside hydraulic ram can weaken hydraulic ram run the noise produced.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, entablatrance, 2, cross sill, 3, car, 4, hydraulic ram, 5, hydraulic oil pipe, 6, hydraulic reservoir, 7, hydraulic oil variable rod, 8, retracing spring, 9, rigidity plunger, 10, hydraulic oil overflow mouth, 11, admission port, 12, rubber mount, 13, hydraulic valve, 14, hydraulic oil pump, 15, fire-proof sound insulation protective cover.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, hydraulic elevator, comprises entablatrance 1 arranged in parallel and cross sill 2, and the upper surface of entablatrance 1 is provided with car 3, and the upper surface of cross sill 2 is provided with hydraulic gear; The hydraulic reservoir 6 that hydraulic gear is comprised hydraulic ram 4 and is connected by hydraulic oil pipe 5 with hydraulic ram 4, hydraulic oil pipe 5 is divided into Liang Tiao branch by a general branch, wherein a branch is provided with hydraulic valve 13, an other branch is provided with hydraulic oil pump 14.The inside of hydraulic ram 4 is provided with hydraulic oil variable rod 7, hydraulic oil variable rod 7 upper and lowers are provided with retracing spring 8, the top of hydraulic oil variable rod 7 is provided with the rigidity plunger 9 matched with hydraulic ram 4, the nearly top of hydraulic ram 4 is provided with hydraulic oil overflow mouth 10, and the nearly top of rigidity plunger 9 offers admission port 11.Such design makes the oil pressure in hydraulic ram keep stable, and then improves the coefficient that operates steadily of lift car 3
Wherein, the top of rigidity plunger 8 is provided with the rubber mount 12 that can contact with car 3, and rubber mount 12 can reduce the rigidity friction of rigidity plunger 8 pairs of cars 3, improves the service life of car 3.
The periphery of hydraulic ram 4 is coated with fire-proof sound insulation protective cover 15, and hydraulic ram 4 is once occur oil spilling phenomenon, and fire-proof sound insulation protective cover 15 can the hydraulic oil that overflows of splendid attire, effectively prevent hydraulic oil pollution external environment, stopped the generation of fire; Meanwhile, because the operation noise of hydraulic ram 4 is very large, so the fire-proof sound insulation protective cover 15 outside hydraulic ram 4 can weaken during hydraulic ram 4 runs the noise produced.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
