Description

Braking device for rim of engineering truck

Technical Field

The utility model belongs to the technical field of the vehicle brake, concretely relates to arresting gear for machineshop car rim.

Background

A brake is a common device that has a function of decelerating, stopping, or maintaining a stopped state of a moving member (or a moving machine), and is a machine component that stops or decelerates the moving member in the machine. And is therefore colloquially referred to as a brake or brake. The brake mainly comprises a braking frame, braking parts, an operating device and the like, and some brakes are also provided with automatic adjusting devices of braking part gaps. In order to reduce the braking torque and the structural size, the brake is usually mounted on the high-speed shaft of the equipment, but large equipment (such as a mine hoist, an elevator and the like) with higher requirements on safety is mounted on the low-speed shaft close to the working part of the equipment.

At present, a rear axle service brake commonly used by the existing engineering vehicle is also used as a parking brake, and the design has the advantages of low cost, simple structure and the like, but when the hand brake is parked, the force required to be acted on a hand brake handle is larger, and the larger the load is, the larger the required acting force is; moreover, the existing brake of the engineering vehicle is mostly of an integral disc structure, is troublesome to install and has short service life.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a braking device for machineshop car rim, have characteristics such as braking effect is good, simple structure, simple to operate, adopt split type structure, low in production cost can extensively be used for the braking system field of machineshop car rim.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a braking device for a rim of a machineshop truck is of a split structure and comprises a brake, an upper brake block and a lower brake block; the brake is respectively connected with an upper brake block and a lower brake block; the brake is of a cross structure, and the surface of the brake is provided with an arc surface; the upper brake block is of an arc-shaped structure and is provided with an upper groove; the lower brake block is of an arc-shaped structure and is provided with a lower groove.

As a modification, the upper brake block and the lower brake block are of a symmetrical structure.

As an improvement, the upper groove and the lower groove are both rectangular structures and are respectively embedded into the upper end and the lower end of the brake.

As an improvement, the length of the upper groove and the length of the lower groove are 0.5-1.2 mm longer than the length of the upper end and the lower end of the brake.

As an improvement, the surface of the brake is provided with a steel seal, and the surface of the brake is sprayed with antirust paint.

As an improvement, the brake is made of one of high-strength carbon steel or wear-resistant structural ceramic materials.

The utility model has the advantages that: the braking device for the rim of the engineering truck has the characteristics of good braking effect, simple structure, convenience in installation and the like; by adopting a split structure, the brake device is divided into a brake, an upper brake block and a lower brake block, and the brake, the upper brake block and the lower brake block are connected in an embedded manner through the groove, so that the connection of the brake is more convenient and stable, and the braking effect of the brake is improved; through adopting high strength carbon steel or wear-resisting structure ceramic material, improved the wear resistance of stopper to improve the life of stopper, the utility model discloses an engineering vehicle rim stopper can extensively be used for the braking and the brake field of engineering vehicle rim.
