Abstract
The utility model relates to a braking device, particularly a hydraulic elevator braking device after improving structure. The utility model discloses a hydraulic elevator braking device, which comprises a controlling device and an acting device. The acting device comprises a pair of safety tongs. The safety tongs comprise a pair of fixed wedging block and a pair of movable wedging block. The pair of fixed wedging block and the pair of movable wedging block are distributed right and left on both sides of a guide rail. The fixed wedging block is fixed on the car box. The controlling device comprises a rocker, a springing device, a block of tractive electromagnet and a bracket, wherein the bracket is fixedly connected to the car box; the rocker is hinged with the car box through a supporting point; the springing device and one end of the tractive electromagnet are fixed on the bracket; the springing device and the other end of the tractive electromagnet are connected to the rocker; the end of the rocker far away from the supporting point is connected with the movable wedging block in the actuating device through a rope. The utility model has the advantages of sensitive braking and simple structure.
Description
Technical field
The utility model relates to a kind of brake gear, especially relates to the brake gear of the hydraulic elevator behind a kind of structural improvement.
Background technology
Hydraulic elevator is oil-feed and the return oil system that adopts hydraulic pressure, lifting pulsation-free advantage is arranged, simultaneously because the flow of hydraulic oil and flow velocity are under pressure and the restriction of the radius of oil pipe itself, so its descending speed generally can not strengthen suddenly, so the people is just arranged in the design of hydraulic elevator, ignored the oil cylinder fracture, pipeline ruptures etc. make the danger that oil cylinder fast descends and brings, and this danger itself is outwardness, cause unnecessary accident, the sensitivity of all wishing brake simultaneously in the process that requires to brake is high, but a lot of water brakes that adopt can cause the phenomenons of braking and lagging behind.
Summary of the invention
The utility model provides the brake gear of the highly sensitive hydraulic elevator of a kind of mechanical type.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of brake gear of hydraulic elevator, comprise control setup and executive device, executive device comprises safety tongs, safety tongs comprises a pair of decide contract piece and a pair of moving contract piece, a pair ofly decide the both sides that contract piece and a pair of moving contract piece are distributed in guide rail about all, deciding the contract piece is fixed on the cab, described control setup comprises fork, springing, tractive magnet and support, support is fixedly connected on the cab, fork is hinged by fulcrum and cab, one end of springing and tractive magnet is fixed on the support, an other end of springing and tractive magnet is connected on the fork, the linking to each other with moving contract piece in the executive device by rope away from an end of fulcrum of fork.
As preferably, described springing is a spring.Select spring for use, simple in structure, cost is lower.
As preferably, between rope and moving contract piece, be provided with to help and try to stop people from fighting each other, help an end of trying to stop people from fighting each other to be connected with rope, the other end links to each other with two moving contract pieces.Helping tries to stop people from fighting each other can make two moving contract pieces keep synchronous braking, is connected with rope better simultaneously.
As preferably, described rope is walked around a tightening device, and described tightening device comprises tension wheel, and tension wheel is fixedly connected on the cab by spring, and rope is walked around tension wheel.Increasing tightening device can avoid the rope work time to grow existing relaxation.
As preferably, on each root guide rail of hydraulic elevator, all be provided with executive device, executive device links to each other with the fork of control setup by rope.On each root guide rail, all be provided with executive device, just can shaking phenomenon just can not occur braking so that whole cab is braked simultaneously.
So it is sensitive to the utlity model has braking, advantage of simple structure.
Description of drawings
Fig. 1 is a structural representation schematic diagram of the present utility model.
Fig. 2 is the structural representation schematic diagram during normal operation among the embodiment 1 of the present utility model.
Fig. 3 is the structural representation schematic diagram in when brake among the embodiment 1 of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings 1, accompanying drawing 2 and accompanying drawing 3, the technical solution of the utility model is described in further detail.
When faults such as the oil cylinder fracture do not occur causes cab to descend fast, tractive magnet 3 is to keep "on" position, fork 1 is subjected to the pulling force from tractive magnet 3, and this time, spring on the control setup just is in pressured state, and fork 1 just has been subjected to the tension force from spring (position as shown in Figure 2), simultaneously, between moving contract piece 8 and the guide rail 9 certain interval is arranged, cab can be freely along guide rail 9 oscilaltions.
When faults such as the oil cylinder fracture occur causes cab to descend fast, tractive magnet 3 is in off-position, tractive magnet 3 just can not produce pulling force to fork 1, and simultaneously, fork 1 is under the effect of the tension force of spring, along fulcrum upward to swing, just lift moving contract piece 8 by rope 5, when moving contract piece 8 along wedge inclined-plane upward movement, moving contract piece 8 is just drawn close (referring to position shown in the accompanying drawing 3) to T type guide rail, just and a lot of friction force of T type guide rail generation, just can play the effect of braking.
Behind trouble removal, can be with tractive magnet 3 energisings, moving contract piece 8 can have been got back to the position shown in the accompanying drawing 2 again, recovers normal operation.
