RU183836U1 - Device for mechanical connection of conveyor belts - Google Patents

Abstract

A device for the mechanical connection of conveyor belts refers to mechanical connections and is used for joining conveyor belts used on conveyors of agricultural, mining, construction and road and general industrial purposes, operated at transshipment points, warehouses, metallurgical and cement plants, mines and sections of the mining industry, sorting plants, in processing complexes, elevators, processing plants, quarries. The features of the device is that in the conical portion of the upper presser plate formed with different grooves inclined faces. The face located at an angle of 25 ° is designed to reduce resistance when tightening the screw, and the face located at an angle of 45 ° is designed to resist spontaneous unscrewing of the screw during operation. The technical result is to increase the reliability of the junction of conveyor belts by preventing spontaneous unscrewing of the mechanical screw connections.

Description

The proposed utility model relates to mechanical joints and is used for joining conveyor belts used on conveyors of agricultural, mining, construction and road and general industrial purposes, operated at transshipment points, warehouses, metallurgical and cement plants, mines and sections of the mining industry, at sorting plants, at processing complexes, elevators, concentration plants, quarries.

MKI class F16G 3/08

A device for connecting conveyor belts, adopted as a prototype (RF patent for utility model No. 163414), including:

- upper and lower pressure plates of a hexagonal shape with through central holes;

- a nut rigidly fixed in the through central hole of the lower pressure plate;

- a connecting screw passing through the central holes of the pressure plates and having a drill at its end, the upper pressure plate having a recess congruent to the head of the connecting screw;

- protrusions on the inner surfaces of the pressure plates;

- recesses symmetrically located between the protrusions on the inner surface of the upper pressure plate;

The disadvantage of the prototype is the possibility of spontaneous unscrewing the screw of the mechanical connection of conveyor belts during operation and, as a consequence, a decrease in the reliability of the connection.

The proposed technical solution is aimed at improving the reliability of the junction of conveyor belts by preventing spontaneous unscrewing of the screw of the mechanical connection.

The problem is solved in that grooves are made on the conical part of the upper pressure plate, moreover, the grooves are made with differently inclined faces.

A face located at an angle of 25 ° will provide a decrease in resistance when tightening the screw during installation of the mechanical connection.

The second face, located at an angle of 45 °, will provide resistance to spontaneous unscrewing of the screw during operation of the mechanical connection of the conveyor belt.

The essence of the utility model is illustrated by drawings, where in FIG. 1 is a sectional view of the mechanical connection of the conveyor belt; FIG. 2 shows the upper pressure plate; FIG. 3 shows a section of grooves with corners.

In the figures, the positions indicated:

1 - lower pressure plate with a through central hole with a pressed-in nut;

2 - upper clamping plate with a through central hole and grooves on the conical part;

3 - connecting screw.

The connection consists of the following components:

1 connecting screw with a special element of a self-tapping screw at the end to improve the passage through the rubber layers, and connects the upper and lower plates of the connecting structure clamping the surface of the conveyor belt. The protruding part of the screw with a self-tapping screw is cut off with special equipment so as not to impede further operation of the conveyor belt.

2 two pressure plates mounted on both sides of the connecting mechanism. Bottom plate with a through central hole and a pressed-in nut with a flange Mb. The upper plate with a through central hole, on the conical part of which there are grooves with differently inclined faces, made ... by stamping. The plates serve for fixing and prevent the rotation of the connecting structure after installation.

The maximum thickness of the mechanical connection of conveyor belts is 40 mm.

Claims (2)

1. A device for mechanically connecting conveyor belts comprising an upper clamping plate with a through central hole, a lower clamping plate with a through central hole and a pressed-in nut, a connecting screw with a self-tapping screw for a cut at the end, characterized in that the conical part of the upper clamping plate is made grooves, and grooves with differently inclined faces are made. 2. The device according to p. 1, characterized in that for the resistance to spontaneous unscrewing of the screw during operation of the joint, one face is located at an angle of 45 °, and to reduce resistance when tightening the screw, the second face is located at an angle of 25 °.
