Description

TECHNICAL FIELD

[0001] The utility model relates to the field of belt conveying, in particular to a carrier roller frame convenient for replacing carrier roller. BACKGROUND

[0002] The belt conveyor is a commonly used material conveying equipment, which can be widely applied to the industries of metallurgy, coal, traffic, electric power, building material, chemical industry, light industry, grain and machinery, and is an important conveying equipment for conveying coal in the electric power enterprise.

[0003] The working environment of the belt conveyor is generally poor, a large amount of dust is generated by the impact at the material falling point and is accompanied by induced wind, causing the dust to overflow. The material guide groove is installed at the material falling point to achieve the purpose of dust reduction and dust removal. Because the lower end of the side plate of the material guide groove is close to the belt, and in order to improve the sealing effect, the anti-overflow apron is tightly pressed on the belt, so that the replacement space of the carrier roller located below the material guide groove is insufficient. When the carrier roller below the material guide groove needs to be replaced due to failure, the material guide groove side plate above the failed carrier roller can only be disassembled to provide sufficient space, which increases the maintenance difficulty and cost.

[0004] Therefore, we propose a carrier roller frame convenient for replacing carrier roller to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] In order to solve the above technical problems, the utility model provides a carrier roller frame convenient for replacing carrier roller.

[0006] The carrier roller frame convenient for replacing carrier roller provided by the utility model, which comprises a crossbeam, an intermediate support, an outer support, a carrier roller, a connecting plate, a base, and a bolt, the intermediate support is symmetrically welded and fixed on the crossbeam, the intermediate support is provided with a first installation groove and a second installation groove, the carrier roller is installed between the first installation grooves of the two intermediate supports, the outer support is symmetrically welded and fixed at the end of the crossbeam, the top end of the outer support is provided with a third installation groove, the carrier roller is installed between the second installation groove of the intermediate support and the third installation groove of the outer support, the connecting plate is fixed at the two ends of the crossbeam, the crossbeam is placed in the arc groove of the base, and the connecting plate and the base are connected by the bolt.

[0007] Preferably, the crossbeam adopts a circular tube structure.

[0008] Preferably, the base is provided with an arc groove which is embedded with the outer circular surface of the crossbeam, and the crossbeam can rotate in the arc groove.

[0009] Compared with the related art, the utility model has the following beneficial effects:

[0010] After the bolts between the connecting plate and the base are disassembled, the crossbeam can rotate in the circular arc groove, and as the rotation amplitude increases, the distance between the carrier roller and the belt also increases, until the space requirement for replacing the carrier roller is met, and the carrier roller can be easily taken out and placed from the middle support and the outer support. The scheme has simple structure and is very convenient to install and disassemble. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0019] The utility model will be further described below in combination with the drawings and embodiments.

[0020] Please refer to Figures 1 to 7 A carrier roller support convenient for replacing the carrier roller mainly comprises a crossbeam 1 and various components fixed on the crossbeam 1. The crossbeam 1 is symmetrically welded with middle supports 2, and the middle supports 2 are provided with first installation grooves 21 and second installation grooves 22.

[0021] In response to the middle supports 2, the crossbeam 1 is also symmetrically welded with outer supports 3. The outer supports 3 are provided with third installation grooves 31 at the top ends.

[0022] The sidewalls at both ends of the rotating shaft 41 of the carrier roller 4 are symmetrically provided with clamping grooves 42, and the clamping grooves 42 can accurately cooperate with the first installation grooves 21, the second installation grooves 22 and the third installation grooves 31, so that the carrier roller is stably and rotatably installed on the carrier roller support.

[0023] Furthermore, the crossbeam 1 adopts a round tube structure, and the crossbeam 1 is further fixed with a connecting plate 5, the crossbeam 1 is placed in an arc groove 61 of the base 6, and the connecting plate 5 is bolted with the base 6. The crossbeam 1 is embedded with the arc groove 61 and can rotate in the groove.

[0024] After the bolt between the connecting plate 5 and the base 6 is disassembled, the crossbeam 1 can rotate in the arc groove 61, and with the increase of the rotating amplitude, the distance between the carrier roller 4 and the belt is also increased, until the space requirement for replacing the carrier roller 4 is met, and the carrier roller 4 can be easily taken out and placed from the middle support 2 and the outer support 3. The scheme has simple structure and is very convenient to install and disassemble.

[0025] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation by using the utility model specification and the attached drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
