Technical Field
The invention relates to a roller structure, in particular to a roller structure suitable for a belt conveyor, and belongs to the technical field of belt conveyors.
Background
The belt conveyor is also called as a rubber belt conveyor, and is widely applied to various industries such as household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and the like, and the assembly, detection, debugging, packaging, transportation and the like of objects. The belt conveyor has the characteristics of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can conveniently carry out programmed control and automatic operation.
A belt conveyor is a friction-driven machine that transports material in a continuous manner. Mainly comprises a frame, a conveying belt, a carrier roller, a tensioning device, a transmission device and the like. The cylinder of belt conveyor usually includes the barrel, radials and drum shaft, the barrel of traditional belt conveyor's cylinder usually carries out fixed connection through radials and drum shaft fixed mounting connection, and carries out fixed connection through the mode of key-type connection between radials and the drum shaft, but the mode of key-type connection can cause installation or dismantlement and inconvenient, need adopt the press to install or dismantle from the axial direction usually to the belt conveyor cylinder of large tonnage, waste time and energy, not only efficiency is lower, and operating personnel intensity of labour is big moreover, the potential safety hazard is big.
Disclosure of Invention
In order to solve the problems, the invention provides a roller structure of a belt conveyor, which can be conveniently mounted or dismounted and is particularly suitable for the belt conveyor.
In order to achieve the purpose, the roller structure of the belt conveyor comprises a roller shaft, a roller body, a radial plate and a connecting end cover.
The drum shaft is of a stepped shaft structure, the mounting position of the drum body positioned in the middle of the drum shaft is a large-diameter section, and the left end and the right end of the large-diameter section of the drum shaft are respectively provided with an external thread structure with opposite rotation directions.
The wheel disk is arranged in two pieces symmetrically left and right relative to the cylinder body, the wheel disk is fixedly connected with the cylinder body, and a roller shaft mounting hole allowing a roller shaft to pass through is formed in the center of the wheel disk.
The connecting end covers are arranged in two pieces in bilateral symmetry relative to the barrel, the two connecting end covers are respectively installed at two ends of the roller shaft in a sleeved mode, the two connecting end covers are respectively installed on the large-diameter section of the roller shaft in a screwed mode through internal thread structures matched with the external thread structures of the large-diameter section of the roller shaft, and the two connecting end covers are further fixedly installed and connected with the radial plate through installation bolts arranged in the axial direction of the two connecting end covers.
As a further improvement of the invention, an elastic gasket is arranged between the connecting end cover and the spoke plate.
As a further improvement of the invention, the external thread structure of the large-diameter section of the drum shaft is a trapezoidal thread structure.
Compared with the prior art, in this belt conveyor cylinder installation, with fixedly connected with radials barrel integral hoisting and cup joint on the epaxial big footpath section of drum back, connect the end cover with two respectively soon at the both ends about the big footpath section of drum axle, then through construction bolt with two connect the end cover respectively with radials fixed mounting connection can, owing to there is not key-type connection structure, consequently need not adopt the press pressure equipment, only can realize quick installation or dismantlement through driving hoist and mount, specially adapted belt conveyor.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1. the roller comprises a roller shaft 2, a roller body 3, a radial plate 4 and a connecting end cover.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the roller structure of the belt conveyor comprises a roller shaft 1, a roller body 2, a web 3 and a connecting end cover 4.
The drum shaft 1 is of a step shaft structure, a large-diameter section is arranged at the mounting position of the drum body positioned in the middle of the drum shaft 1, and external thread structures with opposite rotation directions are respectively arranged at the left end and the right end of the large-diameter section of the drum shaft 1.
The wheel disk 3 is arranged in two pieces symmetrically left and right relative to the cylinder body 2, the wheel disk 3 is fixedly installed and connected with the cylinder body 2 through bolts or welded and fixedly connected, and a roller shaft installation hole allowing the roller shaft 1 to penetrate through is formed in the center of the wheel disk 3.
The connecting end covers 4 are arranged in two pieces in bilateral symmetry relative to the barrel body 2, the two connecting end covers 4 are respectively sleeved at two ends of the roller shaft 1 and are respectively screwed on the large-diameter section of the roller shaft 1 through internal thread structures matched with the external thread structures of the large-diameter section of the roller shaft 1, and the two connecting end covers 4 are respectively fixedly installed and connected with the radial plate 3 through installing bolts arranged along the axial direction of the two connecting end covers.
In the process of mounting or dismounting the belt conveyor roller, the roller body 2 fixedly connected with the radial plate 3 is integrally hoisted and sleeved on the large-diameter section on the roller shaft 1, the two connecting end covers 4 are respectively screwed at the left end and the right end of the large-diameter section of the roller shaft 1, and then the two connecting end covers 4 are respectively fixedly mounted and connected with the radial plate 3 through mounting bolts. Because there is not key connection structure, consequently need not adopt the press pressure equipment, only can realize quick installation or dismantlement through driving hoist and mount. Roller shaft 1 drives barrel 2 rotatory in the belt conveyor work process, because the left and right ends of the big footpath section of roller shaft 1 are equipped with the external screw thread structure that turns to opposite respectively, and barrel 2 passes through radials 3 and connecting end cover 4 and roller shaft 1 location erection joint, consequently barrel 2 can not produce rotary motion for roller shaft 1.
In order to prevent the connecting end cover 4 from rotating and retreating due to vibration and the like, and further prevent the mounting bolt from bearing extra torque, as a further improvement scheme of the invention, an elastic gasket is further arranged between the connecting end cover 4 and the spoke plate 3.
Because the trapezoidal thread has self-locking performance, in order to prevent the connecting end cover 4 from rotating and retreating due to vibration and the like, and further prevent the mounting bolt from bearing extra torque, as a further improvement scheme of the invention, the external thread structure of the large-diameter section of the drum shaft 1 is a trapezoidal thread structure.
