Problems solved by technology

The holding force of the "electromagnet" installed in the middle is 2.5 times greater than the holding force of the upper electromagnet, so the volume, weight, copper wire weight and electric energy of the "electromagnet" installed in the middle are all important. It is 2.5-3 times larger than the electromagnet installed in the upper part, and although the "electromagnet" installed in the upper part only needs 2 / 5 of the holding force of the "electromagnet" in the middle, the stroke of the electromagnet installed in the upper part It is indeed increased by 2.5-3 times, and the existing "electromagnet" (short stroke) installed on the upper part can only be installed on a full range of small-sized brakes

Embodiment Construction

[0017] The outer block brake includes a left brake arm 1, a right brake arm 2, a base 3, a left brake shoe 4, a right brake shoe 5, an electromagnet 6, a brake spring 7 and a rectifier controller 9. The lower ends of the left brake arm 1 and the right brake arm 2 are hinged on the base 3, the two ends of the brake spring 7 are hinged on the left brake arm 1 and the right brake arm 2, the left brake shoe 4 and the right brake The tiles 5 are respectively installed on the left brake arm 1 and the right brake arm 2. The key point of the structure is that the electromagnet 6 is a mid-stroke electromagnet. The electromagnet 6 is arranged above the brake spring 7 and is located on the left brake arm 1. , between the right brake arm 2. The rear end of the electromagnet 6 is fixedly connected with a push-pull connecting plate 8 by bolts. The rectifier controller 9 is fixedly installed on the push-pull connecting plate 8, and the push-pull connecting plate 8 is hinged with the right b...

Abstract

A breaker comprises left and right breaking arms, a base, left and right pads, electromagnet, breaking spring, breaking rod and commute controller. The left and right breaking arms are jointly linked to the two ends of the base. The breaking spring links the top ends of the arms. The breaking pads are fixed to the middle of the breaking arms. The electromagnet is installed in between the two arms and to the top of the spring. The electromagnet is an intermediate range one and to the back end of it fixed a joint board on which fixed the commute controller. The joint board is jointly linked to the right arm. The front end of the electromagnet is slidingly linked to the left arm through a supporting board. The sliding rod to the front end of the electromagnet is matching against the left arm.

Description

(1) Technical field [0001] The invention relates to a brake device, in particular to an outer pad brake. (2) Background technology [0002] External pad brakes are widely used in hoisting, transportation and heavy machinery equipment. Existing external pad brakes mainly include electromagnetic block brakes, electrohydraulic block brakes and hydraulic electromagnetic block brakes. Among them, the electrohydraulic block brake has problems such as high cost, low operating frequency, and large volume; the hydraulic electromagnetic block brake has basically been eliminated; and the electromagnetic block brake can be divided into two types according to the installation position of the electromagnet. One is to install the "electromagnet" on the middle side of the brake, and the other is to install the "electromagnet" on the upper side of the brake. Due to the mechanical structure brake arm lever principle. The holding force of the "electromagnet" installed in the middle is 2.5 ti...
