Description

Technical Field

[0001] This utility model relates to an assembled belt roller structure. Background Technology

[0002] In belt conveyors used in industries such as coal mining, mining, and ports, trough idler assemblies are used to support the conveyor belt and materials. Ordinary fixed trough idlers have non-adjustable side roller angles and spacing. In practical applications, due to differences in the characteristics of the conveyed materials, belt width, belt speed, and other factors, different requirements are placed on the trough shape of the idlers. Existing fixed idlers cannot adapt to these changes, easily leading to problems such as belt misalignment and material spillage.

[0003] Therefore, there is an urgent need for an assembled belt idler structure that can flexibly adjust the angle and spacing of the side rollers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an assembled belt idler structure that can flexibly adjust the angle and spacing of the side rollers.

[0007] The base plate has a boss at its center.

[0008] A horizontal support roller assembly is mounted on top of the boss to provide rolling support for the middle section of the belt.

[0009] Two lateral support roller groups are provided, located on either side of the horizontal support roller group, to provide inclined support to both sides of the bottom of the belt.

[0010] A sliding assembly is provided, which slides in conjunction with the base plate. The lateral support roller group is mounted via the sliding assembly to change the distance between the lateral support roller group and the horizontal support roller group.

[0011] An angle adjustment component is fixed to the sliding component to adjust the tilt angle of the lateral support roller group.

[0012] Preferably, the horizontal support roller assembly includes side brackets, a first central shaft, and a horizontal roller. Two side brackets are provided and are fixedly fixed to the top of the boss in a symmetrical manner. The first central shaft is fixedly installed between the two side brackets.

[0013] Preferably, guide grooves are machined on the top of the base plate at the left and right sides of the boss, and the sliding assembly slides laterally along the guide grooves.

[0014] Preferably, the guide groove is a dovetail groove.

[0015] Preferably, the sliding assembly includes a slide block and a first screw. The bottom of the slide block is provided with a slider that fits into the guide groove. The top of the slide block is provided with a rotating groove. A through first threaded hole is provided on the side of the slide block, and the first threaded hole is parallel to the guide groove. One end of the first screw is fitted with a first bearing on the side of the boss. The first screw fits into the first threaded hole. The other end of the first screw is provided with a first rotating part. A bearing seat is fixedly installed on the base plate. The first screw passes through the bearing seat. A second bearing is fitted between the first screw and the bearing seat. The angle adjustment assembly is fixed to the slide block. The lateral support roller group is rotatably installed through the rotating groove, and the support roller is supported on the bottom of the lateral support roller group.

[0016] Preferably, the angle adjustment assembly includes a platform, a second screw, an adjustment frame, and a support roller; the platform is fixed to the slide block, and a vertical plate is provided at the end of the platform away from the slide block. The bottom of the vertical plate acts on the base plate. The adjustment frame passes through the side of the vertical plate and slides laterally along the vertical plate. An installation shaft is fixed at the end of the adjustment frame extending above the platform. The support roller is fitted onto the installation shaft. A third bearing is fitted between the support roller and the installation shaft. The second screw is located at the end of the vertical plate away from the boss. A fourth bearing is fitted between the second screw and the vertical plate. A second threaded hole is provided at the adjustment frame to engage with the second screw. A second rotating part is provided at the end of the second screw away from the vertical plate. The support roller is supported at the bottom of the lateral support roller assembly.

[0017] Preferably, the bottom of the vertical plate is provided with a relief groove, through which the first screw passes.

[0018] Preferably, the lateral support roller assembly includes a base, a second central shaft, and lateral rollers. The second central shaft is fixedly installed inside the base, and the lateral rollers are coaxially mounted on the second central shaft. A fifth bearing is fitted between the lateral rollers and the second central shaft. An ear plate is provided at the bottom position of the base near the boss, and a pin is fitted between the ear plate and the rotating groove. The ear plate rotates coaxially along the pin. The base is supported by the support rollers.

[0019] Preferably, an annular positioning groove is provided on the outer wall of the support roller, and the base cooperates with the positioning groove.

[0020] The beneficial effects of this utility model are:
