Abstract

The utility model belongs to the technical field of belt conveyors, in particular to a unidirectional rotation turnabout drum, which comprises a drum support shaft, wherein the drum support shaft is sleeved with the turnabout drum through a bearing, one side of the bearing close to the inner cavity of the turnabout drum is axially limited by a connection cover plate of the turnabout drum, one side of the bearing far away from the inner cavity of the turnabout drum is axially limited by the cover plate, and the cover plate is detachably connected with the connection cover plate; the roller supporting shaft positioned in the inner cavity of the turnabout drum is provided with a telescopic device, and the roller supporting shaft positioned in the inner cavity of the turnabout drum is also provided with a movement direction detection device for detecting the rotation direction of the turnabout drum. This application is through the motion state of inspection driven roll, and when driven roll opposite direction rotated or stop motion, the telescoping device stretched out, with the inboard in close contact with of driven roll, stops driven roll's motion, reaches the emergence that prevents conveyer belt counter rotation phenomenon.

Description

Unidirectional rotation turnabout drum

Technical Field

The utility model belongs to the technical field of the belt conveyor, concretely relates to unidirectional rotation driven roll.

Background

A belt conveyor is a major bulk material conveying apparatus. The bend pulley mainly changes the trend of the conveyer belt or plays a role in supporting the conveyer belt in the belt conveyor, and the conveyer belt drives the bend pulley to rotate. When the conveyer inclines and upwards transports, emergency shutdown is often required in the working process when meeting sudden conditions, and when the conveyer is shut down, the downward sliding force generated by the dead weight of the materials on the conveyer belt can drive the conveyer belt to move in the opposite direction and is in an accelerating state in the moving process, so that the reverse direction galloping phenomenon of the conveyer belt is finally formed.

Disclosure of Invention

In order to overcome the shortcomings of the prior art, the utility model provides an unidirectional rotation driven roll reaches the emergence that prevents the conveyer belt reverse rotation phenomenon through the direction of rotation of restriction driven roll.

The utility model discloses a realize through following technical scheme: a unidirectional rotation turnabout drum comprises a drum support shaft, wherein the drum support shaft is sleeved with a turnabout drum through a bearing, one side of the bearing close to the inner cavity of the turnabout drum is axially limited by a connecting cover plate of the turnabout drum, one side of the bearing far away from the inner cavity of the turnabout drum is axially limited by a cover plate, and the cover plate is detachably connected with the connecting cover plate; the roller supporting shaft positioned in the inner cavity of the turnabout drum is provided with a telescopic device, and the roller supporting shaft positioned in the inner cavity of the turnabout drum is also provided with a movement direction detection device for detecting the rotation direction of the turnabout drum.

Furthermore, two telescopic devices are symmetrically arranged on the roller supporting shaft.

Furthermore, the telescopic device is an electro-hydraulic push rod.

The utility model has the advantages that: this application is through the motion state of inspection driven roll, and when driven roll opposite direction rotated or stop motion, the telescoping device stretched out, with the inboard in close contact with of driven roll, stops driven roll's motion, reaches the emergence that prevents conveyer belt counter rotation phenomenon.

Detailed Description

The invention will be further explained below with reference to the drawings and examples.

As shown in fig. 1, a unidirectional rotation bend drum comprises a drum support shaft 1, the drum support shaft 1 is sleeved with a bend drum 3 through a bearing 2, one side of the bearing 2 close to the inner cavity of the bend drum 3 is axially limited by a connecting cover plate 31 of the bend drum 3, one side of the bearing 2 far away from the inner cavity of the bend drum 3 is axially limited by a cover plate 6, and the cover plate 6 is detachably connected with the connecting cover plate 31; the drum supporting shaft 1 positioned in the inner cavity of the turnabout drum 3 is provided with a telescopic device 4, and the drum supporting shaft 1 positioned in the inner cavity of the turnabout drum 3 is also provided with a movement direction detection device 5 for detecting the rotation direction of the turnabout drum 3. The during operation cylinder back shaft 1 is fixed, and turnabout drum 3 rotates, and when the cylinder barrel did not rotate or the reverse rotation, direction of motion detection device 5 sent the signal, and the controller sends the instruction, installs the action of telescoping device 4 on cylinder back shaft 1, promotes the telescopic link and stretches out, and the telescopic link contacts with the inboard barrel of turnabout drum 3, prevents turnabout drum 3's reverse rotation to reduce the functioning speed of conveyer belt, reduce the emergence of driving accident.

As a modification of this embodiment, two of the telescopic devices 4 are symmetrically disposed on the drum supporting shaft 1. When the reverse motion of the turnabout drum 3 needs to be prevented, the two expansion devices 4 are simultaneously extended, and the effect of preventing the reverse rotation of the turnabout drum 3 is better.

The telescoping device 4 described in this application is an electro-hydraulic push rod.
