Description

Vacuum tire rim for forklift

Technical Field

The utility model belongs to the technical field of the industrial vehicle rim, concretely relates to shaped steel class flat radials rim.

Background

The forklift belongs to an industrial carrying vehicle, is a vehicle running at low speed and high load, is known as a good helper for work carrying, and is widely applied to places needing heavy object carrying, such as warehouses, ports, factories and the like. Traditional fork truck steel ring mostly is equipped with the inner tube of a tyre, also adopts solid child a bit, like patent number "201520051592. X" introduced a fork truck and used solid child rim, it includes interior half rim, outer half rim and dish of stopping, through combining dish of stopping with the rim as an organic whole, rim simple structure, low in production cost, but solid child elasticity is poor, the driving vibrations are felt strong, with high costs, also influences fork truck's life simultaneously.

The vacuum tire is a pneumatic tire without an inner tube, which is also called a low-pressure tire or a pneumatic tire, has high elasticity and wear resistance, good adhesive force and heat dissipation performance, and can meet the requirements of a forklift on safety, sealing performance and environmental protection, but the forklift needs to meet the requirement of high load. Therefore, the rim capable of being matched with the vacuum tire of the forklift is designed, and has important application value.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a vacuum child rim for fork truck, have intensity height, security good, sealing performance characteristics such as good, can satisfy fork truck's vacuum tire and match operation requirement.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a vacuum tire rim for a forklift comprises a rim body, a retainer ring and a locking ring; the rim body is provided with a first groove and a second groove, a locking ring is placed in the first groove, and an O-shaped sealing ring is arranged in the second groove; the outer side of the retainer ring is an outward-bent arc, and the inner side of the retainer ring is provided with a right-angle groove structure; the retainer ring is also provided with a pressing extension part.

As an improvement, the rim body is provided with a valve hole.

As a modification, the rim body is provided with spokes therein, the spokes being located close to the small-diameter end of the rim body.

As an improvement, the spoke is provided with a bolt hole.

As an improvement, the bolt holes are circularly and uniformly distributed on the spokes, and the number of the bolt holes is 6-8.

As an improvement, the rim body is made of high-strength section steel.

The utility model has the advantages that: a vacuum tire rim for a forklift has the characteristics of simple structure, high strength, good sealing performance and good safety; the rim adopts an integral structure, so that the strength is higher, and the appearance is attractive; the sealing performance is improved by arranging the groove for placing the locking ring and the O-shaped sealing ring on the rim body; in addition, through the extension that compresses tightly that sets up on the lock collar, improved the effect that the lock collar compressed tightly the tire for fork truck under high load, guarantee that the tire does not drop, be favorable to improving fork truck's security performance.
