Abstract
The utility model discloses a hydraulic damping type elevator speed-limiting device, comprising a ratchet (1), a lifting rod (3) connected with the ratchet (1), a speed-limiting arm (4) and a speed-limiting block (5) mounted on the speed-limiting arm (4), characterized in that: the elevator speed-limiting device also comprises a hydraulic damper and a telescoping rod (7) on the hydraulic damper passes through the speed-limiting arm (4) to be connected with the lifting rod (3). The hydraulic damping type elevator speed-limiting device keeps the structure of the existing speed-limiting device and adds one hydraulic damper on the existing braking device, so as to increase the stability of the speed-limiting and prolong the service life of a rope pulley with small impact force during speed-limiting process.
Description
Technical field
The utility model relates to a kind of velocity limiter, particularly a kind of Hydrautic damping elevator governor that is applied to elevator.
Background technology
Elevator governor adopts ratchet to drive lifting rod at present, and the pulling force that lifting rod overcomes spring drives the action of speed limit arm, and the speed limit piece on the speed limit arm compresses rope sheave, plays the effect of speed limit.But impulsive force is big in this speed limit process, and the impulsive torque that poor stability, rope sheave are subjected to is big, influences its service life.
The utility model content
The purpose of this utility model is, a kind of Hydrautic damping elevator governor is provided.Stability when it can improve speed limit, impulsive force is little in the speed limit process, can prolong the service life of rope sheave.
The technical solution of the utility model: a kind of Hydrautic damping elevator governor, comprise ratchet, be connected lifting rod, the speed limit arm on the ratchet and be installed in speed limit piece on the speed limit arm, it is characterized in that: also comprise hydraulic damper, the expansion link on the described hydraulic damper passes the speed limit arm and is connected with lifting rod.
In the aforesaid Hydrautic damping elevator governor, described control cock is parallel with check valve.
In the aforesaid Hydrautic damping elevator governor, the cavity of any side of described piston is provided with Fill valve.
In the above-mentioned Hydrautic damping elevator governor, described hydraulic damper comprises hydraulic actuating cylinder, is provided with piston in the hydraulic actuating cylinder, and the cavity of piston both sides is connected with control cock through hydraulic pipe, and piston is connected with expansion link, is with spring on the expansion link.
Compared with prior art, the utility model has kept the structure of existing system velocity limiter, has increased a hydraulic damper on existing drg, the stability during with the raising speed limit, and impulsive force is little in the speed limit process, can prolong the service life of rope sheave.The utlity model has simple in structurely, speed limit is effective, the characteristics that improvement cost is low.The utility model can be realized unidirectional damping, goes back the scalable damping, and conveniently hydraulic damper is carried out repairing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: the 1-ratchet, the 2-rope sheave, the 3-lifting rod, 4-speed limit arm, 5-speed limit piece, the 6-spring, the 7-expansion link, the 8-piston, the 9-hydraulic actuating cylinder, the 10-control cock, the 11-check valve, the 12-Fill valve, 13-gets rid of piece, 14-retracing spring, 15-ratchet.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.The Hydrautic damping elevator governor, constitute as shown in Figure 1, comprise ratchet 1, be connected lifting rod 3, the speed limit arm 4 on the ratchet 1 and be installed in existing parts such as speed limit piece 5 on the speed limit arm 4, it is characterized in that: also comprise hydraulic damper, the expansion link 7 on the described hydraulic damper passes speed limit arm 4 and is connected with lifting rod 3.Hydraulic damper comprises hydraulic actuating cylinder 9, is provided with piston 8 in the hydraulic actuating cylinder 9, and the cavity of piston 8 both sides is connected with control cock 10 through hydraulic pipe, and piston 8 is connected with expansion link 7, is with spring 6 on the expansion link 7.Control cock 10 is parallel with check valve 11.The cavity of piston 8 any sides is provided with Fill valve 12.
The utility model is by hydraulic damper, finishes being connected of speed limit arm 4 and lifting rod 3.When rope sheave 2 velocities of rotation are too fast, be installed on the rope sheave 2 get rid of piece 13 since centrifugal effect to rope sheave 2 movement outside, because getting rid of piece 13 fuses with ratchet 15, and can rotate around the axle that is fixed on the rope sheave 2, so when getting rid of piece 13 outside moving, ratchet 15 inwardly motion blocks ratchet 1, ratchet 1 rotates with rope sheave 2, ratchet 1 drives lifting rod 3, lifting rod 3 drives 4 actions of speed limit arm, and the speed limit piece 5 on the speed limit arm 4 compresses rope sheave 2, plays the effect of speed limit, retracing spring 14 can guarantee rope sheave 2 when normal speed is moved, and ratchet 15 can not block ratchet 1.Owing to be subjected to the influence of interior hydraulic flow of hydraulic damper and spring 6, make speed limit piece 5 and rope sheave 2 on the speed limit arm 4 realize soft the contact, actv. has reduced impact, has reduced the impact moment that rope sheave is subjected to, and has improved speed limit stability.For the ease of adjusting buffering effect, the cavity of piston 8 both sides is connected with control cock 10 through hydraulic pipe, by regulating the flow of control cock 10, can change the damping of hydraulic damper.Be parallel with check valve 11 at the two ends of control cock 10, can realize unidirectional damping.In order to guarantee to be full of hydraulic oil in the hydraulic damper all the time, the cavity of piston 8 any sides is provided with Fill valve 12, can conveniently replenish hydraulic oil to hydraulic damper.
