Description

Technical Field

[0001] The utility model relates to the field of conveyor lines, in particular to a hydraulically driven rotating mechanism. Background Art

[0002] The rotating mechanism of the current pre-baked anode carbon block conveyor line uses a motor to drive the reduction box, and then the gearbox uses a worm gear drive method and a drive shaft to connect the roller to rotate to achieve the desired carbon block movement direction. The use of this traditional rotating mechanism has the following disadvantages:

[0003] Firstly, the operation stability is poor. As the gearbox adopts the transmission mode of worm gear inside, the long-term continuous operation will cause the loss caused by mechanical motion properties such as mechanical vibration and the friction between the worm gear and the worm gear, resulting in the gradual increase of the fitting clearance. As a result, there will be a residual deviation after the rotation is in place, which will cause inaccurate docking with the next mechanism, resulting in limit failure, thus affecting the operation of the carbon block, and even causing equipment failure, resulting in maintenance and production costs.

[0004] Secondly, the equipment has high repair and maintenance costs. The internal mechanism of the worm gear reducer wears out quickly during long-term operation. The replacement cycle of parts is short, the frequency of replacement of parts is high, and the space for replacing parts or repairing the mechanism is small, resulting in difficulties in repair, replacement of parts, and long repair time.

[0005] Third, the operating energy consumption is relatively high. The rotating mechanism of the motor-direct-driven worm gear reducer has much higher power loss than the rotating mechanism driven by the hydraulic gear reducer. The power of the hydraulically driven rotating mechanism is lower than that of the original rotating mechanism, so the energy loss per unit time is about one-third lower.

[0006] Fourthly, it occupies a large space and has a relatively single operating environment. Compared with the hydraulically driven rotating mechanism, the original rotating mechanism occupies a large space due to its own mechanism characteristics, and the applicable environment is inflexible and single. Due to the high ambient temperature in special scenes, the original rotating mechanism has relatively poor operating efficiency and stability. Utility Model Content

[0007] Based on this, the purpose of the utility model is to provide a hydraulically driven rotating mechanism to solve the technical problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulically driven rotating mechanism, comprising a driving box, a rotating shaft is installed in the driving box for rotation along the vertical direction, the top end of the rotating shaft passes through the driving box and is fixedly connected to a gear plate, a hydraulic motor is fixedly installed on one side of the driving box, and the output shaft of the hydraulic motor is fixedly connected to a reduction gear meshing with the gear plate.

[0009] By adopting the above technical solution, the rotating mechanism combined with the hydraulic drive method can adjust the rotation speed according to the working conditions, changing the traditional single speed rotation. The characteristics of the hydraulic control determine that the rotation process can achieve a smooth effect and can achieve precise docking with the next mechanism.

[0010] The utility model is further configured that a gear cover for protecting the reduction gear and the toothed disc is fixedly mounted on the outer wall of the driving box.

[0011] By adopting the above technical solution, the gear cover can effectively prevent the reduction gear and the gear plate from being disturbed by external factors during operation.

[0012] The utility model is further configured that a first rolling bearing and a second rolling bearing are sequentially connected between the driving box and the rotating shaft from top to bottom.

[0013] By adopting the above technical solution, the effective rotating shaft will have an axis deviation during the rotation process.

[0014] The utility model is further configured that a thrust ball bearing is installed at the bottom end of the rotating shaft in the driving box.

[0015] By adopting the above technical solution, the thrust ball bearing can provide good support for the rotating shaft in the axial direction.

[0016] The utility model is further configured that the top end of the toothed disc is connected with a rotating roller via a mounting bracket.

[0017] By adopting the above technical solution, the direction of the rotating roller can be adjusted.

[0018] The utility model is further configured such that the toothed disc and the reduction gear are both in a horizontal state.

[0019] By adopting the above technical solution, the reduction gear can output power to the gear plate more stably.

[0020] The utility model is further configured that a lubricating oil chamber is arranged inside the driving box between the first rolling bearing and the thrust ball bearing, and an oil filling port connected to the lubricating oil chamber is opened on the side wall.

[0021] By adopting the above technical solution, the rotating shaft can rotate more smoothly by injecting lubricating oil into the lubricating oil cavity.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model can adjust the rotation speed according to the working conditions by combining the rotating mechanism with hydraulic drive, changing the traditional single speed rotation. The characteristics of hydraulic control determine that the rotation process can achieve a smooth effect, and can achieve accurate docking with the next mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A hydraulically driven rotary mechanism, such as Figure 1 As shown, it includes a drive box 1, in which a rotating shaft 3 is installed to rotate in a vertical direction, the top of the rotating shaft 3 passes through the drive box 1 and is fixedly connected to a gear plate 5, a hydraulic motor 2 is fixedly installed on one side of the drive box 1, and the output shaft of the hydraulic motor 2 is fixedly connected to a reduction gear 4 meshing with the gear plate 5, and a gear cover 9 for protecting the reduction gear 4 and the gear plate 5 is fixedly installed on the outer wall of the drive box 1, and the gear cover 9 can effectively prevent the reduction gear 4 and the gear plate 5 from being disturbed by external factors during operation, and the diameter of the gear plate 5 is customized according to actual production conditions to achieve transmission of a specific gear ratio between the reduction gear 4 and the gear plate 5.

[0033] See also Figure 1The top of the toothed disc 5 is connected to a rotating roller 10 through a mounting bracket. The rotating roller 10 is used to transport prebaked anode carbon blocks. When the hydraulic motor 2 is working, the angle of the toothed disc 5 is adjusted to adjust the direction of the rotating roller 10. The toothed disc 5 and the reduction gear 4 are both in a horizontal state, so that the reduction gear 4 can output power to the toothed disc 5 more stably.

[0034] Embodiment 2

[0035] A hydraulically driven rotary mechanism, such as Figure 1 As shown, on the basis of embodiment one, the difference from embodiment one lies in that a first rolling bearing 6 and a second rolling bearing 7 are sequentially connected between the drive box 1 and the rotating shaft 3 from top to bottom, and the first rolling bearing 6 and the second rolling bearing 7 are utilized to limit the rotating shaft 3, so that the axis of the effective rotating shaft 3 is offset during the rotation process, and a thrust ball bearing 8 is installed at the bottom end of the rotating shaft 3 in the drive box 1, and the thrust ball bearing 8 can provide good support for the rotating shaft in the axial direction.

[0036] See also Figure 1 A lubricating oil chamber is provided inside the driving box 1 between the first rolling bearing 6 and the thrust ball bearing 8, and an oil filling port connected to the lubricating oil chamber is opened on the side wall. By injecting lubricating oil into the lubricating oil chamber, the rotating shaft 3 can rotate more smoothly, which is beneficial to improving the stability of the rotating roller 10 during rotation.

[0037] The working principle of the utility model is as follows: when the rotating roller 10 needs to rotate, the hydraulic motor 2 works to rotate the reduction gear 4, and the reduction gear 4 engages with the toothed disc 5 and drives the toothed disc 5 to rotate, and the rotating roller 10 connected above the toothed disc 5 can adjust its direction. The hydraulically driven rotating mechanism of the hydraulic motor 2 can operate very stably, so that the rotating roller 10 after rotation can be accurately docked with the next workstation.
