Problems solved by technology

[0003]In the underground mining of coal mines, a large number of belt conveyors are used in various transportation links. The replacement of belt conveyor parts is part of the work content of daily equipment maintenance, especially the belt conveyor Rollers are used in a large amount and have a high replacement rate. Most of the belt conveyor rollers in the prior art are replaced manually by multiple people with a simple crowbar. The process of prying with the crowbar is easy to strain the belt. Accidents that cause crowbars to hurt people or break equipment, and many people cooperate manually, waste labor resources and increase production costs. Therefore, we propose an auxiliary device for replacing the idler rollers of belt conveyors in coal mines to solve the above problems. question

Embodiment 1

[0038] The inside of fixed groove 1 is provided with locking mechanism 14, and locking mechanism 14 comprises the locking plate 141 that is slidably installed on the outer wall of transmission bin 7, and slide rail 143 is installed on the outer wall of transmission bin 7, and locking plate 141 is slidably installed on On the slide rail 143, the inner side of the locking plate 141 is provided with a rubber layer, the locking plate 141 is rotatably equipped with a locking screw 142, the locking screw 142 runs through the fixing groove 1, and the locking screw 142 is threadedly connected with the fixing groove 1, The outer ends of the locking screw 142 and the adjusting screw 4 are provided with rotating handles. After the fixing groove 1 is clamped on the longitudinal beam of the belt conveyor, by rotating the locking screw 142, the locking screw 142 drives the locking plate. 141 extrusion beams make this device fixed.

Embodiment 2

[0040] Such as Figure 5As shown, the locking mechanism 14 includes a locking plate 141 slidably mounted on the outer wall of the transmission bin 7, a slide rail 143 is installed on the outer wall of the transmission bin 7, the locking plate 141 is slidably installed on the slide rail 143, and the locking plate 141 There is a rubber layer on the inner side of the seat tube clamp 144 on the locking plate 141, the seat tube clamp 144 runs through the fixing groove 1, and the seat tube clip 144 is slidably matched with the fixing groove 1, and the fixing groove 1 is clamped to the belt conveyor. After the longitudinal beam is mounted, the device is fixed by rotating the handle at the outer end of the seat pipe clamp 144 and pulling the locking plate 141 to squeeze the longitudinal beam.

[0041] In this embodiment, when in use, the fixing grooves 1 on both sides are pulled, and the squeeze rollers 6 at both ends are respectively inserted on the two ends of the idler rollers of t...

Abstract

The invention relates to the technical field of coal mining, and discloses a coal mine underground belt conveyor carrier roller replacement auxiliary device which comprises two fixing grooves with openings facing the same direction, and a guide rod is arranged between the two fixing grooves; the outer side of the fixing groove is sleeved with a clamping groove, and an adjusting lead screw is arranged on the end face of the clamping groove in a penetrating mode and is in threaded connection with the clamping groove. Connecting rods are rotationally mounted on the two sides of the clamping groove correspondingly, and extrusion rollers are arranged at the outer ends of the two connecting rods correspondingly. A transmission bin is arranged in the fixing groove, an inner threaded pipe is rotationally installed between the inner wall of the upper end and the inner wall of the lower end of the transmission bin, a second bevel gear is arranged on the inner threaded pipe, and the two ends of the inner threaded pipe are in threaded connection with transmission lead screws. According to the device, by rotating the adjusting lead screw, the extrusion rollers are driven to move backwards to pull the belt, and meanwhile the extrusion rollers on the two sides are driven to be away from each other to open the belt, so that the belt is separated from the carrier roller, and the carrier roller is convenient to replace.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to an auxiliary device for replacing idler rollers of belt conveyors in coal mines. Background technique [0002] Belt conveyor is the abbreviation of belt conveyor, there are fixed type and mobile type, simple structure and high efficiency. Continuous conveying machinery with flexible conveyor belts as material bearing and traction components. An endless conveyor belt loops around the drive and redirection pulleys. The upper and lower branches between the two drums are each supported by a number of rollers. The material is placed on the upper branch, and the conveyor belt and the material are driven by the friction between the driving roller and the belt. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions, and can also be used in assembly lines for certain process operations. Simple structure, stable and reliable work, stron...
