Description

Technical Field

[0001] This utility model relates to the field of load-bearing device technology, and in particular to a hydraulic assisted support device. Background Technology

[0002] A ball mill is a heavy-duty grinding device that uses a rotating drum to drive grinding media to impact and grind materials. The ball mill drum must be supported by a reliable support device; this is a core prerequisite for its safe, stable, and efficient operation. The total weight of the drum itself and its internal grinding media (such as steel balls), materials, liners, etc., can reach tens or even hundreds of tons, and it needs to rotate continuously to complete the grinding operation. Without a suitable support device, the drum simply cannot operate. In existing technology, the two ends of the drum are rotatably connected to the frame via bearings, and its weight is borne by the bearing assemblies at both ends. However, the greater the force on the bearing assemblies, the greater the frictional resistance to the drum's rotation, which is detrimental to the drum's rotation. Simultaneously, the drum is supported at both ends, while the bottom of the middle section is suspended, subjecting the middle section to immense downward pressure. This increases the probability of drum deformation, affecting normal operation and service life. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic auxiliary support device with a simple and reasonable structural design and convenient use; it can extend into the bottom of the rotating drum to assist in supporting part of the drum's weight, thereby reducing the pressure between the drum and the rotating connection and reducing the drum's rotational resistance.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A hydraulically assisted support device includes a mounting base, a hydraulic cylinder, a slide, a follower turntable, and tapered roller bearings. The mounting base is horizontally arranged and includes a left seat and a right seat, which are parallel and spaced apart. The slide includes a bearing housing, tapered roller bearings, and two optical shafts. The bearing housing is horizontally arranged, with its front and rear ends respectively connected to the horizontally arranged optical shafts, and has a bearing mounting cavity on it. The tapered roller bearing is installed inside the bearing mounting cavity. The tapered roller bearing includes an inner ring, an outer ring, a cage, and a plurality of tapered rollers. The outer wall of the outer ring is connected to the inner wall of the bearing mounting cavity, and the top of the inner ring is connected to the follower turntable.

[0006] The left and right seats are each equipped with two horizontally arranged linear bearings; the left and right ends of the optical axis are respectively inserted into the linear bearings and slidably connected to them. The left and right ends of the optical axis are also equipped with limiting rings to prevent the ends from being pulled out of the linear bearings when the optical axis moves.

[0007] The follower turntable is used to support the roller of the ball mill. It is located in the middle of the bottom of the roller and supports some of the roller's weight. Since the roller rotates when it is working, the follower turntable also needs to rotate with the roller.

[0008] The follower turntable is disc-shaped and horizontally arranged. Its outer wall is a conical surface, its top is provided with a dust cover plate, and its bottom is provided with a limiting annular groove.

[0009] The bottom of the follower turntable is fitted onto the top of the inner ring; the top of the inner ring is located within the limiting annular groove;

[0010] The bottom of the follower turntable is also provided with a limiting protrusion ring, and the bearing mounting cavity is provided with a limiting ring groove, and the limiting protrusion ring is inserted into the limiting ring groove.

[0011] A hydraulic cylinder is horizontally mounted above the right (or left) seat, and the output shaft of the hydraulic cylinder is connected to the slide block; the hydraulic cylinder pushes and pulls the slide block, causing the slide block to move left and right.

[0012] The beneficial effects of this utility model are:

[0013] Its structural design is simple and reasonable, and it is easy to use; it can extend into the bottom of the rotating drum to help support part of the drum's weight, thereby reducing the pressure between the drum and the rotating connection and reducing the drum's rotational resistance.

[0014] Its supporting power is flexible hydraulic pressure, which can buffer and protect the stressed components. Attached Figure Description

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figures 1-7 As shown, a hydraulic auxiliary support device includes a mounting base 1, a hydraulic cylinder 2, a slide 3, a follower turntable 4, and a tapered roller bearing 5;

[0024] The mounting base 1 is horizontally arranged and includes a left base 11 and a right base 12, which are arranged in parallel at intervals.

[0025] The slide block 3 includes a bearing housing 31 and two optical shafts 32. The bearing housing 31 is horizontally arranged, with its front and rear ends respectively connected to the horizontally arranged optical shafts 32, and a bearing mounting cavity 30 is provided on it. A tapered roller bearing 5 is provided in the bearing mounting cavity 30. The tapered roller bearing 5 includes an inner ring 51, an outer ring 52, a cage, and a plurality of tapered rollers 53. The outer wall of the outer ring 52 is connected to the inner wall of the bearing mounting cavity 30, and the top of the inner ring 51 is connected to the follower turntable 4. A plurality of tapered rollers 53 are disposed between the inner ring 51 and the outer ring 52.

[0026] The left seat 11 and right seat 12 are each provided with two horizontally arranged linear bearings 13; the left and right ends of the optical axis 32 are respectively inserted into the linear bearings 13 and slidably connected to the linear bearings 13. The left and right ends of the optical axis 32 are also provided with limiting retaining rings 33 to prevent the ends of the optical axis 32 from being pulled out of the linear bearings 13 when the optical axis 32 moves.

[0027] The follower turntable 4 is used to support the roller 6 of the ball mill. It is located in the middle of the bottom of the roller 6 and supports some of the weight of the roller 6. Since the roller 6 rotates when it is working, the follower turntable 4 also needs to rotate with the roller 6.

[0028] The follower turntable 4 is disc-shaped and horizontally arranged. Its outer wall is a conical surface 41, its top is provided with a dust cover plate 42, and its bottom is provided with a limiting annular groove 40.

[0029] The bottom of the follower turntable 4 is sleeved on the top of the inner ring 51; the top of the inner ring 51 is located within the limiting annular groove 40.

[0030] The bottom of the follower turntable 4 is also provided with a limiting protrusion ring 43, and the bearing mounting cavity 30 is provided with a limiting ring groove 44, and the limiting protrusion ring 43 is inserted into the limiting ring groove 44.

[0031] A hydraulic cylinder 2 is horizontally mounted above the right seat 12 (or left seat 11), and the output shaft 21 of the hydraulic cylinder 2 is connected to the slide 3; the hydraulic cylinder 2 pushes and pulls the slide 3, causing the slide 3 to move left and right.

[0032] Optionally, the outer ring 52 is integrally formed with the slide block 3.

[0033] Optionally, a dust cover 22 is provided on the outside of the output shaft of the hydraulic cylinder 2.

[0035] Optionally, the slide 3 and the optical axis 32 are integrally formed.

[0036] Briefly describe its support principle:

[0037] like Figure 7 As shown, when this application is used to support a ball mill, if the drum 6 is conventionally horizontally positioned, the outer wall of the drum 6 is provided with a load-bearing ring 61, and the side wall of the load-bearing ring 61 near the follower turntable 4 is a conical surface 62. When the drum 6 requires a hydraulically assisted support device to assist in bearing a certain weight, the hydraulic cylinder 2 pushes the slide 3 to move, so that the conical surface 41 of the follower turntable 4 fits against the conical surface 62 of the load-bearing ring 61 of the drum 6, thereby bearing part of the weight; as the hydraulic cylinder 2 continues to push, the conical surface 41 can also slightly push against the conical surface 62, causing the middle section of the drum 6 to rise slightly, thereby bearing more weight, or offsetting the slight downward movement of the middle section of the drum 6 caused by gravity. At the same time, when the drum 6 rotates, the follower turntable 4 supports the drum 6 and is driven to rotate by the drum 6. The follower turntable 4 rotates horizontally, and the drum 6 rotates in its radial direction (similar to two vertically meshing bevel gears).

[0038] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
