Abstract

The utility model discloses a simple belt reverse rotation prevention device, which comprises baffle plates uniformly distributed on the side surface of a belt tail wheel roller at intervals and baffle rods hinged on a roller bearing base; the baffles are distributed in a divergent shape; the movable end of the blocking stick is lapped on the top surface of the inner side of the baffle plate across the center of the roller, and the movable end can swing up and down for a certain angle; the telescopic spring is arranged between the top surface of the hinged end of the blocking roller and the roller bearing base, and the roller bearing is used on a transportation belt for climbing transportation and has the effect of preventing the belt and the roller from reversing.

Description

Simple belt reverse rotation preventing device

Technical Field

The utility model relates to a simple belt reverse rotation prevention device which is used on a transportation belt for climbing transportation and prevents the belt from reversing.

Background

Because of the condition restriction, there is the transportation belt of climbing transportation in the factory building more, this kind of climbing belt appears the belt suddenly and has a power failure and the belt skids when the condition when the belt skids in the in-process of belt transportation material, can lead to the belt to overturn, and the material is whole to be piled up unrestrained falling material, and the clearance degree of difficulty is big, and recovery time is long, influences production.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a simple belt reverse rotation prevention device which can prevent a belt from reversing.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:

a simple belt reverse rotation preventing device comprises baffle plates which are uniformly distributed on the side surface of a belt tail wheel roller at intervals and a baffle roller hinged on a roller bearing base; the baffles are distributed in a divergent shape; the movable end of the blocking stick is lapped on the top surface of the inner side of the baffle plate across the center of the roller, and the movable end can swing up and down for a certain angle; and an expansion spring is arranged between the top surface of the hinged end of the blocking roller and the roller bearing base.

The technical scheme of the utility model is further improved as follows: the baffle plates are distributed on the side surface of the roller at the position close to the boundary.

The technical scheme of the utility model is further improved as follows: the number of the baffles is six.

The technical scheme of the utility model is further improved as follows: the blocking stick is hinged on the roller bearing base through a movable shaft.

Due to the adoption of the technical scheme, the utility model has the technical progress that:

when the roller normally rotates, the blocking stick can rotate downwards under the stirring of the roller baffle until the blocking stick is separated from the baffle, and then the blocking stick can bounce and fall onto the next baffle under the elastic action of the telescopic spring, so that the normal operation of the roller is not influenced; once the roller rotates reversely (abnormal reverse rotation), the blocking stick can be pushed reversely until the lower part of the previous blocking plate is propped against the roller to block the roller, so that the effect of preventing the belt and the roller from rotating reversely is achieved.

Drawings

FIG. 1 is a schematic view of the drum of the present invention in a normal direction of rotation;

FIG. 2 is a schematic view of the drum according to the present invention in an abnormal reverse rotation;

the roller bearing device comprises a roller 1, a roller 2, a baffle plate 3, a roller bearing base 4, a baffle rod 5 and a telescopic spring.

Detailed Description

The present invention will be described in further detail with reference to the following examples:

as shown in FIG. 1, a simple belt reverse rotation preventing device comprises baffle plates 2 uniformly distributed on the side surface of a belt tail wheel roller 1 at intervals; the baffles 2 are distributed divergently, and are optimally arranged to be distributed at the positions close to the boundary on the side surface of the roller 1, and the number of the baffles is generally six.

The roller bearing further comprises a blocking stick 4 which is hinged on the roller bearing base 3 and matched with the baffle 2, and the blocking stick 4 can swing up and down for a certain angle; the hinged end of the blocking stick 4 is higher than the center of the roller 1, the movable end of the blocking stick crosses the center of the roller 1 and is lapped on the top surface of the inner side of the baffle 2, and the length of the blocking stick 4 can be just lapped on the baffle 2. And an expansion spring 5 is arranged between the top surface of the hinged end of the blocking stick 4 and the roller bearing base 3.

Furthermore, the blocking stick 4 is hinged on the roller bearing base 3 through a movable shaft.

The using method comprises the following steps:

as shown in fig. 1, when the roller 1 normally rotates, the blocking stick 4 can rotate downwards under the stirring of the roller baffle 2 until the blocking stick is separated from the baffle 2, and then the blocking stick can bounce to the next baffle 2 under the elastic force of the telescopic spring 5, so that the normal operation of the roller 1 is not affected; once the roller 1 is reversed (abnormal reverse rotation), the blocking stick 4 will be pushed in reverse direction until it will press the lower part of the previous blocking plate 2 to block the roller 1, which will prevent the belt and roller from reversing.
