Description

Slow-release windproof electrohydraulic brake unit

Technical Field

The utility model belongs to the technical field of the stopper, concretely relates to electricity liquid braking unit is prevent wind to slowly-releasing.

Background

The brake is mainly applied to braking and speed reduction in equipment such as large and medium-sized cranes, port loading and unloading machinery, metallurgical machinery, transportation machinery, mining machinery and the like, rail clamping devices are commonly used in scenes such as windproof braking and positioning of outdoor portal crane trolleys, a conventional electric hydraulic rail clamping device needs to be equipped with a hydraulic station to work, when the hydraulic station is electrified, a hydraulic cylinder works, and a spring is compressed to realize a brake release state; therefore, it is necessary to provide a slow-release windproof electrohydraulic brake unit which avoids brake failure, reduces brake failure, has high integration level, is convenient to install and has high safety performance.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, and provide one kind and avoid the braking trouble, reduce the braking inefficacy, the high simple to operate of integrated level, the electricity liquid braking unit is prevent wind in the slowly-releasing that the security performance is high.

The purpose of the utility model is realized like this: the utility model provides a slowly-releasing windproof electric liquid brake unit, it includes the base, the intermediate position of base is provided with spring unit, spring unit's upside is connected with the one end of lever, the upside at power unit is connected to the other end of lever, spring unit's expansion end front and back symmetry is provided with even board, two the tip downside of even board articulates respectively has the brake arm, the lower extreme fixedly connected with brake shoe of brake arm, two the middle part of brake shoe corresponds the guide rail position, the lower part of base is provided with the bottom plate, swing joint has the guide pulley on the bottom plate, the upside of base is located the intermediate position of spring unit and power unit and is provided with the locating lever, the upper end and the lever of locating lever are articulated.

The base is L-shaped, and a support plate is obliquely arranged on the base.

The power unit is an electric hydraulic thruster.

The spring in the spring assembly is a cylindrical spring or a rectangular spring.

The utility model has the advantages that: the utility model relates to a slowly-releasing windproof electric liquid braking unit adopts the electro-hydraulic impeller as the power unit, has abandoned traditional pneumatic cylinder and hydraulic pressure station, has avoided causing the braking trouble because of reasons such as hydraulic pressure station or pipeline oil leak to the power unit highly integrated into an organic whole has solved the problem of current space installation, has still improved the security performance simultaneously; the spring in the spring assembly adopts a cylindrical or rectangular spring, so that the traditional belleville spring is abandoned, and the problem of brake failure caused by the fragmentation of the belleville spring can be reduced; when the electric hydraulic pusher is powered on, the push rod of the electric hydraulic pusher is quickly lifted, and the brake shoe is opened through the lever and the brake arm; when the power is off, the push rod of the electro-hydraulic thruster descends rapidly under the action of the spring force and closes the brake arm through the lever action; the utility model has the advantages of avoid the braking trouble, reduce the braking inefficacy, the high simple to operate of integrated level, the security performance is high.

FIG. 2 is a right side view of the slow release windproof electric hydraulic brake unit of the present invention;

fig. 3 is a top view of the slow-release windproof electrohydraulic brake unit of the present invention.

In the figure: 1. the device comprises a base 2, a spring assembly 3, a lever 4, a power unit 5, a connecting plate 6, a brake arm 7, a brake shoe 8, a guide rail 9, a bottom plate 10, a guide wheel 11, a positioning rod 12 and a support plate.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-3, the slow-release windproof electrohydraulic brake unit comprises a base 1, a spring assembly 2 is arranged in the middle of the base 1, the upper side of the spring assembly 2 is connected with one end of a lever 3, the other end of the lever 3 is connected with the upper side of a power unit 4, link plates 5 are symmetrically arranged at the front and back of the movable end of the spring assembly 2, the lower sides of the end portions of the two link plates 5 are respectively hinged with a brake arm 6, the lower end of the brake arm 6 is fixedly connected with a brake shoe 7, the middle portions of the two brake shoes 7 correspond to the position of a guide rail 8, a bottom plate 9 is arranged at the lower part of the base 1, a guide wheel 10 is movably connected onto the bottom plate 9, a positioning rod 11 is arranged in the middle of the spring assembly 2 and the power unit 4 at the upper side of the base 1, and the upper end of the positioning rod 11 is hinged with the lever 3.

For better effect, the shape of base 1 is L shape, slope on base 1 is provided with the extension board 12, and simple structure is reasonable, is convenient for support and removal.

For better effect, the power unit 4 is an electro-hydraulic thruster.
