The utility model provides a jack-up limiter separates restriction inductor and pulley, when monitoring jack-up quantity, does not receive the influence that the loose pulley axle changes.

Description

Hoisting limiter

Technical Field

The utility model relates to a hoist technical field especially relates to a jack-up limiter.

Background

The hoisting machinery is provided with a hoisting limiter, and when the weight of the hoisted goods exceeds the design value of the hoisting equipment, the hoisting limiter sends out an alarm signal to stop the operation of the hoisting equipment, so that the safe operation of the hoisting equipment is ensured.

At present, the lifting limiter is mainly installed on a pulley shaft, and due to certain deformation of the pulley shaft during operation, the accuracy of monitoring data of the lifting limiter is influenced.

Disclosure of Invention

To the technical problem, the utility model provides a jack-up limiter improves monitoring data's accuracy.

The utility model discloses a specific technical scheme be:

the hoisting limiter comprises a limiting inductor, a fixed seat and a limiting cantilever, wherein the limiting inductor is arranged below the crane arm, and the fixed seat is fixed on the crane arm; one end of the limiting cantilever is hinged with the fixed seat and is positioned below the crane arm; the other end of restriction cantilever is articulated with the restriction inductor, install the pulley on the restriction cantilever, the pulley be located between fixing base and the restriction inductor.

Preferably, the limit inductor is installed below the crane arm through a connecting seat.

Furthermore, the upper end of the connecting seat is hinged below the crane arm, and the upper end of the limiting inductor is connected to the connecting seat.

The connecting seat comprises a vertically arranged tension spring, and the limiting inductor is fixedly connected with the lower end of the tension spring.

Still include and prevent putting the frame, the restriction inductor is located the pulley and prevents putting between the frame, the restriction cantilever other end stretch into prevent putting the frame in the middle of, prevent putting the frame and to the both sides restriction swing of restriction cantilever.

Furthermore, the anti-swing frame is a rectangular frame body, balls are arranged on two sides inside the frame body respectively, and two sides of the limiting cantilever are in rolling contact with the balls respectively.

The utility model provides a jack-up limiter separates restriction inductor and pulley, when monitoring jack-up quantity, does not receive the influence that the loose pulley axle changes.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the anti-swing frame.

Detailed Description

The technical solution of the present invention is described below with reference to the accompanying drawings and examples.

As shown in fig. 1, the hoisting limiter comprises a limiting inductor 6, the limiting inductor 6 is installed below a crane jib 1, and further comprises a fixed seat 2 and a limiting cantilever 3, wherein the fixed seat 2 is fixed on the crane jib 1; one end of the limiting cantilever 3 is hinged with the fixed seat 2 and is positioned below the crane arm 1; the other end of restriction cantilever 3 is articulated with restriction inductor 6, install pulley 4 on the restriction cantilever 3, pulley 4 be located between fixing base 2 and the restriction inductor 6.

The limit inductor 6 is installed below the crane jib 1 through a connecting seat 5.

The upper end of the connecting seat 5 is hinged below the crane arm 1, and the upper end of the limit inductor 6 is connected to the connecting seat 5.

The connecting seat 5 comprises a vertically arranged tension spring, and the limiting inductor 6 is fixedly connected with the lower end of the tension spring.

The connecting seat 5 is a structure capable of swinging and stretching, and is mainly suitable for limiting the up-and-down swinging of the cantilever 3, and the influence on the limiting inductor 6 in the vertical direction is reduced as much as possible.

As shown in fig. 1 and 2, the anti-swing device further comprises an anti-swing frame 7, the limit sensor 6 is located between the pulley 4 and the anti-swing frame 7, the other end of the limit cantilever 3 extends into the middle of the anti-swing frame 7, and the anti-swing frame 7 limits the swing of two sides of the limit cantilever 3.

The anti-swing frame 7 is a rectangular frame body, two sides in the frame body are respectively provided with a ball 8, and two sides of the limiting cantilever 3 are respectively in rolling contact with the balls 8. The anti-swing frame 7 limits the two sides of the limiting cantilever 3 and prevents the limiting cantilever 3 from swinging left and right.
