Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a tool for replacing a grooved roller of a belt conveyor. Background Art

[0002] Belt conveying is highly efficient and widely used. The existing belt conveyor includes a frame, roller brackets arranged on the frame at intervals along the conveying direction, and a group of groove rollers installed in each bracket. Each group of groove rollers generally has a middle roller (placed horizontally) and two side rollers (placed obliquely) symmetrically arranged on both sides of the middle roller, a total of three rollers, which together hold up the belt; the distance between two adjacent groups of groove rollers is about 1 meter.

[0003] Replacing the rollers of a belt conveyor is a daily task. When the equipment is shut down, two or more workers usually use a crowbar to pry the belt and the drag bar apart by a certain distance and work together to replace it. The wider the belt, the more difficult it is to replace, which is time-consuming and labor-intensive, and has certain safety hazards. A Chinese patent with the authorization announcement number CN 219669268 U discloses a belt lifting device for replacing rollers, including a base frame and a support plate. The support plate is grooved and can lift the belt and simultaneously separate three rollers from the same group of grooved rollers. Although the lifting device of the above patent can easily replace the rollers of the belt conveyor, its lifting consumes a lot of energy, which will cause energy waste when only one roller needs to be replaced. In addition, the support plate is required to have a large arc area, and the support plate is easily deformed by the belt during use. Utility Model Content

[0004] The utility model provides a replacement tool for grooved rollers of a belt conveyor. The tool can partially lift the belt according to replacement requirements to achieve replacement of only one roller, thereby reducing energy consumption, and having a small requirement on the support plate area, and the support plate is not easily deformed.

[0005] A tool for replacing a belt conveyor trough roller comprises a bracket support device that can be stably placed on a belt conveyor frame and a lifting and supporting mechanism located on the bracket support device, the bracket support device comprises a main frame and a triangular support bracket fixedly arranged on the top surface of the main frame, the inclined surface of the triangular support bracket has a second mounting position of the lifting and supporting mechanism corresponding to any side roller of the belt conveyor trough roller; the top surface of the main frame has a first mounting position of the lifting and supporting mechanism corresponding to the middle roller of the belt conveyor trough roller; the first mounting position of the lifting and supporting mechanism is located on the main frame on the inclined surface side of the triangular support bracket; a belt is tensioned on the belt conveyor trough roller, and when replacing the belt conveyor trough roller, the lifting and supporting mechanism is installed at any one of the first mounting position of the lifting and supporting mechanism and the second mounting position of the lifting and supporting mechanism, and a support plate for supporting the belt is provided on the top of the lifting and supporting mechanism.

[0006] Since the bracket support device of the utility model has two installation positions for placing the lifting mechanism, namely the first installation position and the second installation position, when the first installation position is selected to install the lifting mechanism, the lifting mechanism can lift the belt to separate the belt from the middle roller of the belt conveyor, which is convenient for replacing the middle roller; when the second installation position is selected to install the lifting mechanism, the lifting mechanism can lift the belt to separate the belt from the side roller of the belt conveyor, which is convenient for replacing the side roller. The replacement tool of the groove roller of the belt conveyor of the utility model can replace only one of the rollers of the belt conveyor according to the need, which saves energy consumption, has a small requirement for the support plate area, and the support plate is not easy to deform; in general, it has many advantages such as easy use, wide application, simple structure, low cost, light and easy to carry, safe operation, reduced labor intensity, and improved production efficiency.

[0007] Furthermore, the first installation position of the jacking and lifting mechanism has a horizontal surface which is parallel to the central axis of the middle roller of the belt conveyor trough roller.

[0008] Furthermore, the second installation position of the lifting and supporting mechanism has an inclined surface which is parallel to the central axis of any side support of the belt conveyor groove roller.

[0009] Furthermore, the jacking and lifting mechanism also includes a base, and the base is detachably fixed to the bracket supporting device through a screw locking mechanism.

[0010] Furthermore, the support plate is a flat plate structure arranged perpendicular to the telescopic direction of the lifting and supporting mechanism and is not prone to deformation.

[0011] Furthermore, the lifting mechanism is a scissor jack, and the lifting mechanism also includes a pair of upper supporting arms, a pair of lower supporting arms and an adjusting screw, and the adjusting screw is arranged perpendicular to the conveying direction of the belt conveyor. Compared with the existing design in which the adjusting screw is parallel to the conveying direction of the belt conveyor, the adjusting end of the adjusting screw is located on the side of the grooved roller of the belt conveyor, and the adjusting screw is more convenient to adjust.

[0012] Furthermore, a slot for clamping and fixing with the belt conveyor frame is provided at the bottom of the main frame to prevent the main frame from sliding. BRIEF DESCRIPTION OF THE DRAWINGS
