Description

Technical Field

[0001] The utility model relates to the technical field of belt rollers, in particular to a simple and practical replacement device for belt rollers. Background Art

[0002] Belt conveyor rollers are a general term for rollers, including various trough rollers, buffer rollers, parallel rollers, etc. Belt conveyor rollers are the most important component of belt conveyors and also the largest component of belt conveyors. Belt conveyor rollers are different from unpowered rollers used for material transportation, although their composition and appearance are similar. However, belt conveyor rollers have a larger load capacity and have corresponding restrictions on the speed.

[0003] Traditional belt rollers are generally directly installed on the support frame, and their installation position is fixed. For three-roller grooved rollers, they need to be disassembled one by one using tools such as wrenches and screwdrivers when they are disassembled later. After the replacement and installation are completed, the fasteners need to be tightened again, which takes a long time and has low replacement efficiency. Based on this, a simple and practical replacement device for belt rollers is proposed to improve the disassembly and replacement efficiency. Utility Model Content

[0006] Preferably, any of the above schemes is that four limiting holes are opened on both sides of the conveyor belt bracket close to the guide rail, and limiting square columns matching the limiting holes are installed on both sides of the four clamping bevel blocks. By using this scheme, it is convenient to limit the installation of the four clamping bevel blocks. At the same time, after the four clamping bevel blocks are disassembled, it is convenient to make the two first mounting frames and the second mounting frames move in opposite directions, thereby facilitating the increase of the distance between the two adjacent mounting rings, and facilitating the quick removal of the roller body.

By using this scheme, it is convenient to limit the installation position of the first mounting bracket, and at the same time, the two first mounting brackets and the second mounting brackets are symmetrically distributed about the middle position between the conveyor belts, so that the external conveyor belt can be placed on the top surface of the three roller bodies.

[0008] Preferably, any of the above schemes is that the middle parts of the two first mounting frames close to the second mounting frame are fixedly connected to limit rods, and one end of the two limit rods are respectively fitted with the side faces of the second mounting frame. By using this scheme, after the first mounting frame contacts the knife stop block, it indicates that the first mounting frame is installed in place. At the same time, the second mounting frame is pushed by the clamping bevel block, moves in the direction of the first mounting frame, and fits with the limit rod, thereby completing the installation of the second mounting frame.

[0009] Preferably, any of the above schemes is that bearings are provided inside the six mounting rings, and the multiple bearings are grouped in pairs and installed at the two end positions of the three roller bodies. The outer shapes of the two ends of the three roller bodies are conical. The conical structure at the two ends of the roller body in this scheme is convenient for matching with the bearings. At the same time, in the later process of supporting the conveyor belt, the roller body itself can rotate, and the two ends of the roller body and the bearings also rotate relative to each other, thereby relatively reducing the rotation speed of the roller body itself, which helps to extend its service life.

[0010] Preferably, any of the above schemes has two vertical grooves in the middle of the sides of the four clamping rods, and limiting grooves are provided on both sides of the middle of the top surfaces of the four clamping rods, which are respectively connected with the multiple vertical grooves. The structure in this scheme adopts a quick disassembly and assembly structure commonly used in mechanical processing. By adopting the above structure, the nut in the fastener is rotated to a certain distance without being completely unscrewed, so that the nut of the fastener can protrude from the inside of the limiting groove, thereby facilitating the relative movement of adjacent clamping rods and facilitating the quick disassembly of the clamping rod and the clamping bevel block.

The simple and practical replacement device for the belt roller is provided with four clamping oblique blocks, and limiting square columns are installed at both ends of the clamping oblique blocks. The limiting square columns are slidably connected with the limiting holes, so as to facilitate limiting the four clamping oblique blocks. By providing four clamping rods, pressure is applied to the four clamping oblique blocks through fasteners, and the first mounting frame and the second mounting frame are pushed to slide relative to each other, so as to facilitate the matching of the two end positions of the bearing and the roller body, thereby realizing quick installation.

[0014] 3. The simple and practical replacement device for the belt roller is provided with four clamping rods. Two vertical grooves and limit grooves are provided in the middle of the four clamping rods, so that the nuts in the fasteners can be easily inserted into the limit grooves to limit the positions of the four clamping rods.
