Abstract
The invention discloses an elevator over-speed governor which comprises a base, a rope wheel, a support shaft, clamp jaws, a steel wire rope, a switch, a bevel gear, a connecting rod and flyballs, wherein the support shaft is arranged on the base, and the rope wheel is connected onto the support shaft through a rotating shaft; the bevel gear is rotationally connected onto the rotating shaft, the free end of the bevel gear is connected with the flyballs, one end of the connecting rod is connected with flyball arms, and the other end of the connecting rod is connected with the switch which is arranged on the base; and the clamp jaws are arranged in the switch, and the steel wire rope penetrates through the inside of the clamp jaws. According to the elevator over-speed governor, the speed of the elevator steel wire rope linked with the rope wheel is judged through centrifugal force of the flyballs, if the speed exceeds the nominal speed, the flyballs drive the connecting rod to trigger the switch, and the switch pushes the clamp jaws to act to clamp the steel wire rope; and the elevator over-speed governor is simple and reliable in structure and fast in response.
Description
Technical field
The present invention relates to a kind of elevator governor, belong to elevator accessory technical field.
Background technology
At present, in order to ensure the safety of riding personnel and lift facility, speed-limit device is used to prevent car or counterweight accidental falling.Velocity limiter can reflect the real-world operation speed of car or counterweight, when the speed value of reaching capacity, can and produce mechanical power, forces safety tongs action.Common pendulum velocity limiter, the ratchet by pendulum limits steel rope and moves, and in actual practicality, rate of braking and stability are not enough.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of elevator governor.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
An elevator governor, comprises base, rope sheave, pivot shaft, claw, steel rope, switch, also comprises crowngear, connecting rod, gets rid of ball, on described base, is provided with pivot shaft, and described rope sheave is connected on pivot shaft by rotating shaft; In described rotating shaft, be rotationally connected crowngear, crowngear free end is connected with and gets rid of ball, connecting rod one end with get rid of ball arm and be connected, the connecting rod other end is connected with switch; Described switch is arranged on base, is provided with claw in switch, has steel wire penetrating in claw.
The described bag that gets rid of is drawn together two spheroids, two and is got rid of ball arm.
Described claw comprises the first claw, the second claw.
Described the second claw is controlled to the first claw and is clamped by switch.
As preferred version, also comprise spring, described spring is connected with the second claw, for accelerating the reset of the second claw.
Beneficial effect: elevator governor provided by the invention, by getting rid of ball centnifugal force, judge the speed of elevator wire rope interlock rope sheave, as surpassed command speed, get rid of ball drivening rod and touched switch, switch promotes claw action, blocks steel rope.Simple in structure, reliable, reflection rapidly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, an elevator governor, comprises base 1, rope sheave 2, pivot shaft 3, claw 4, steel rope 5, switch 6, also comprises crowngear 7, connecting rod 8, gets rid of ball 9, on described base 1, be provided with pivot shaft 3, described rope sheave 2 is connected on pivot shaft 3 by rotating shaft; In described rotating shaft, be rotationally connected crowngear 7, crowngear 7 free ends are connected with and get rid of ball 9, connecting rod 8 one end with get rid of ball arm 11 and be connected, connecting rod 8 other ends are connected with switch 6; Described switch 6 is arranged on base 1, is provided with claw 4 in switch 6, has steel rope 5 to pass in claw 4.
The described ball 9 that gets rid of comprises that two spheroids 11, two get rid of ball arm 10, gets rid of ball arm 10 and is socketed on crowngear 7 ends, with crowngear 7, rotates.
Described claw 4 comprises the first claw, the second claw.
Described the second claw is controlled and is clamped to the first claw by switch 6.
As preferred version, also comprise spring 12, described spring 12 is connected with the second claw, for accelerating the reset of the second claw.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
