CONNECTOR FOR MECHANICALLY LINKING CONVEYOR BELTS

Abstract

The invention relates to conveyor technology, and specifically to belt conveyors, and can be used in underground mining operations, including in coal mines. A connector for mechanically linking conveyor belts contains an assembly comprising two profiled plates and a connecting element; each profiled plate is provided, in the center thereof, with a through-hole in which the connecting element, in the form of a bolt, is located, the bolt head corresponding to a receiving seat in the upper profiled plate; the inner surfaces of the profiled plates are each provided with symmetrically arranged profiled protrusions, and a nut is pressed into the centrally-located through-hole of the lower profiled plate; the upper profiled plate is equipped with additional tapered holes (recessions) symmetrically arranged between the profiled protrusions, at that these tapered holes (recessions) being provided on the inner surface of the profiled plate.

Claims

1. The connector for mechanical linking of conveyor belts, comprising a set of two profiled plates and a connecting element, wherein each profiled plate has a centrally-positioned through hole locating a bolt-shaped connecting member, the head of which corresponds to the upper profiled plate's bore and the profiled plates' inner surface bears shaped protrusions symmetrically placed; at that a nut is pressed into the lower profiled plate central through hole, characterized in that the additional tapered holes (recessions) are symmetrically arranged between the upper profiled plate's profiled protrusions at the inner surface of the profiled plate.

Description

[0020] The basic concept of this invention is to create a strong, reliable, simple and inexpensive construction of a durable high-quality fastener PWC for mechanical linking of conveyor belts, allowing the installation time to be reduced, while maintaining reliable strength in the joints with the conveyor belt flat level maintained in the edges joint area.

[0021] The claimed device is aimed at improving the design of connector PWC for conveyor belts mechanical linking, thus allowing its use in large area joints, therefore high reliability being ensured through the use of structurally simple mutually independent connectors.

[0022] The set task of the conveyor belts connector PWC, comprising a set of two profiled plates and the connecting element, when each profiled plate have a centrally located through hole, placing a connecting member shaped as a bolt head that corresponds to the upper profiled plate's bore, the inner surface of every plate locating symmetrically the profiled protrusions and the lower profiled plate's central through hole bears a pressed-in nut, is solved by arranging at the upper profiled plate has additional tapered holes (recessions), symmetrically positioned between its profiled projections at the inner surface of the profiled plate.

[0023] The claimed invention novelty is that the upper profiled plate is provided with additional cone-shaped holes (recessions), symmetrically positioned between the profiled protrusions, at that the holes (recessions) being located at the inner surface of the profiled plate.

[0024] The claimed conveyor belts connector PWC (see FIG. 1) includes two profiled plates: the upper 1 and the lower 2, and the connecting element 3 formed as a bolt. Each of the profiled plates 1 and 2 has a centrally positioned through hole 4 arranged to meet the bolt-shaped connecting member 3, which head corresponds to the receiving bore 5 at the upper profiled plate 1. The conveyor belt facing surface of the upper and the lower profiled plates 1, 2 bears the profiled projections 6, intended for the profiled plates' linking to the conveyor belt. The connecting bolt's 3 head end has a hexagon socket meeting the stillson wrench. The bolt rod bears threads for screwing into the nut 7, rigidly pressed into the hole of the bottom profiled plate 2.

[0025] The upper profiled plate 1 also bears additional conical holes or recessions 8 arranged symmetrically between its shaped protrusions 6.

[0026] The lower profiled plate 2 has a centrally-positioned through hole 4, with a pressed-in nut 7 and profiled protrusions.

[0027] The linkage joint is assembled as follows:

[0028] The coupled conveyor belts' ends (refer to FIG. 3), are cut at an angle of 90 with further stepwise processing, degreasing and they are prepared for joining. After drying, the conveyor belts ends are superimposed, rolled-on and hammer-rapped from the middle part to the edges. Then in the conveyor belt joint area drilled are the holes. Next, the profiled plate 1 with its embedded bolt 3, is superposed onto the belt, with further bolt insertion into the conveyor belt opening. On the conveyor belt lower side, the profiled bottom plate 2 is screwed onto the bolt 3. The bolt 3 is screwed into the nut 7 disposed on the lower profiled plate 2. Further the profiled plates 1 and 2 are tightened together using the bolt 3. Thus, all the connecting elements are installed. The bolted joint assemblage is finalized with breaking off the bolted joint's speakers protruding above the conveyor belt.

[0029] The claimed technical result consists in the following: the proposed construction of conveyor belts connector PWC provides a safe operation of the conveyor at the belt gasket strength reaching 1600-2000 N/mm. The tapered through holes or recessions 8 in the upper profiled plate 1 allow the conveyor belt facing surface to be pressed through these holes (recessions) when the connector PWC is pressed against the conveyor belt.

[0030] These substantial differences allow achieving the following technical result: [0031] To increase the rubber conveyor belts end joint's breaching strength; [0032] To reduce the belt flatness discrepancies in the area of the belt ends linkage; [0033] To accelerate the connector PWC installation considering that the lower and upper profiled plates are visually and tactually easily distinguishable due to their different constructional features.
