Abstract

The utility model discloses an overspeed protection device for a winch, which comprises a winch shaft to be test. A velometer is coupled with the shaft, and a travel switch is mounted at the end of a sliding sleeve inside the velometer and is controlled by the sliding sleeve. The utility model can realize the automatic measurement and control of the running speed of the winch and perform overspeed protection, thereby improving the running reliability and security of the winch.

Description

The winch overspeed protection device
Technical field
The utility model relates to a kind of winch, specifically relates to a kind of winch overspeed protection device.
Background technology
Winch is mine, the construction machinery and equipment of using always, and the running velocity of winch is generally manually controlled by operating personal, under unexpected situation, may be owing to the maloperation of operating personal, and the winch overspeed is easy to cause safety misadventure.
Summary of the invention
The utility model aims to provide a kind of winch overspeed protection device with automatic measuring and controlling function.
The technical solution adopted in the utility model is: a kind of winch overspeed protection device, comprise the measured axis of winch, and knotmeter and measured axis connect, and travel switch is installed in the termination of sliding sleeve in the knotmeter, and travel switch is controlled by sliding sleeve.
The running velocity of winch embodies by the rotating speed of measured axis, after knotmeter and measured axis connect, knotmeter and measured axis together rotate, weight on the knotmeter is under action of centrifugal force, make radial motion, drive sliding sleeve and make axial motion, the measured axis rotating speed is high more, and then the axial motion of sliding sleeve distance is long more; When the measured axis rotating speed reached certain value, the axial motion of sliding sleeve distance reached certain threshold value, and travel switch produces switch motion, made the action of winch safety return circuit, made winch automatic deceleration or stopping-down, thereby realized the overspeed protection function of winch.
The utility model can be realized the automatic measuring and controlling to the winch running velocity, and carries out overspeed protection, improves winch reliability of operation and safety widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below, the utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 illustrates a kind of winch overspeed protection device, comprises the measured axis 1 of winch, and knotmeter 2 connects with measured axis 1, and travel switch 5 is installed in the termination of sliding sleeve 4 in the knotmeter 2, and travel switch 5 is subjected to sliding sleeve 4 controls.
Knotmeter 2 rotates under the drive of measured axis 1; weight 3 on the knotmeter 2 is under action of centrifugal force; make radial motion; drive sliding sleeve 4 and make axial motion; when measured axis 1 rotating speed reaches certain value; the axial motion distance of sliding sleeve 4 reaches certain threshold value, and travel switch 5 produces switch motion, and the control safety return circuit produces the protection action.
