Description

Technical Field

[0001] This application relates to the fields of metallurgy and mineral processing technology, and in particular to a large-angle, wide-range adaptive drive power supply adjustment device. Background Technology

[0002] As a conveying device for tailings sedimentation and discharge in the metallurgical and mineral processing industries, the thickener mainly consists of a bridge frame, a rake frame, a drive power supply, a hydraulic device, and a central tank. Its main function is to transport the tailings slurry from flotation through a conveying pipeline into the central tank of the thickener, and then allow the tailings slurry to fall to the bottom of the inclined thickening tank through the discharge hole of the central tank under its own gravity. The rotation of the rake frame evenly settles the fine tailings minerals to the bottom of the thickening tank, and the clear water overflows into the drainage trough, achieving efficient solid-liquid separation. The rotation of the bridge frame and the rake frame is driven by a hydraulic motor, which is powered by the drive power supply.

[0003] The existing drive power supply device consists of components such as slip rings, brush holders, carbon brushes, and pressure springs. Due to the settlement of the foundation around the thickener over the years, the bridge frame of the thickener is misaligned with the central fixed support. The brush holder, which is rigidly connected to the bridge frame, is also misaligned, changing from coaxial motion to irregular eccentric motion. This causes the carbon brushes connected to the brush holder to break due to gap issues. In some cases, the slip ring may even collide directly with the brush holder due to excessive eccentricity, causing deformation of the support column that fixes the brush holder. This results in a high equipment failure rate, high maintenance frequency, and affects the continuous and stable operation of the equipment, indicating room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a large-angle, large-range adaptive drive power supply adjustment device in order to improve the adaptability of the drive power supply adjustment device.

[0005] To achieve the above objectives, the large-angle, wide-range adaptive drive power supply adjustment device provided in this application adopts the following technical solution:

[0006] A large-angle, wide-range adaptive drive power supply adjustment device includes a central cylinder and a support frame disposed on one side of the central cylinder. A slip ring conductive rail cylinder is disposed on the outer wall of the central cylinder. A fixed plate is disposed on the support frame. Several sets of carbon brush adjustment assemblies are symmetrically arranged from the centerline of the fixed plate in the width direction to the edge of the fixed plate in the width direction. Each carbon brush adjustment assembly includes a support arm connecting seat, a carbon brush movable seat, and a movable connector. The support arm connecting seat is disposed on the fixed plate. The support arm connecting seat and the carbon brush movable seat are movably connected through the movable connector. A carbon brush is movably connected to the carbon brush movable seat. When relative movement occurs between the carbon brush and the slip ring conductive rail cylinder, the carbon brush movable seat carries the carbon brush and swings along the support arm connecting seat through the movable connector, and the carbon brush is always in contact with the surface of the slip ring conductive rail cylinder.

[0007] Preferably, the slip ring conductive rail cylinder has the same number of slip ring conductive rails as the carbon brush adjustment components.

[0008] Preferably, the movable connector includes a first connecting arm and a second connecting arm, one end of the first connecting arm and one end of the second connecting arm are movably connected to the fixed plate, and the other end of the first connecting arm and the other end of the second connecting arm are movably connected to the carbon brush movable seat.

[0009] Preferably, an adjusting spring is connected between the end of the first connecting arm that is connected to the fixed plate and the end of the second connecting arm that is connected to the carbon brush movable seat.

[0010] Preferably, the fixing plate is detachably provided with a locking buckle, and the fixing plate is locked to the support frame by the locking buckle.

[0011] Preferably, the width of the slip ring conductive rail and the width of the carbon brush are in a clearance fit.

[0012] Preferably, the slip ring conductive rail cylinder is provided with a terminal, the carbon brush is provided with a connecting wire, and the carbon brush is electrically connected to the slip ring conductive rail cylinder through the connecting wire.

[0013] Compared with the prior art, this utility model provides a large-angle, wide-range adaptive drive power supply adjustment device, which has the following beneficial effects:

[0014] 1. Because the support arm connecting seat and the carbon brush movable seat are movably connected through a movable connector, the carbon brush movable seat can support the carbon brush to move along the slip ring conductive rail cylinder when the central cylinder is in motion. The carbon brush movable seat supports the carbon brush to swing along the support arm connecting seat through the movable connector, so that the carbon brush and the slip ring conductive rail cylinder are in a soft connection state. This reduces the probability of the carbon brush failing to make contact with a part of the slip ring conductive rail cylinder due to the change of the rotation axis of the slip ring conductive rail cylinder when it is in motion, or the contact force between the carbon brush and a part of the surface of the slip ring conductive rail cylinder being too large, thus causing excessive force on the carbon brush or the carbon brush movable seat, resulting in damage to the carbon brush and / or the carbon brush movable seat.

[0015] 2. By cooperating with the slip ring conductive rail and the carbon brush, the path of relative movement between the carbon brush and the slip ring conductive rail cylinder is limited, thereby improving the stability of the cooperation between the carbon brush and the slip ring conductive rail.

[0016] 3. The locking buckle allows for adjustment of the position of the fixing plate on the support frame, thereby indirectly adjusting the relative position between the carbon brush and the slip ring conductive rail. The mechanical structure is simple. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a large-angle, wide-range adaptive drive power supply adjustment device. (Refer to...) Figure 1 and Figure 2 A large-angle, wide-range adaptive drive power supply adjustment device includes a central cylinder 1 and a support frame 2 disposed on one side of the central cylinder 1. A slip ring conductive rail cylinder 3 is disposed on the outer wall of the central cylinder 1. A fixed plate 4 is disposed on the support frame 2. Several sets of carbon brush 521 adjustment components 5 are symmetrically disposed from the centerline of the fixed plate 4 in the width direction to the edge of the fixed plate 4 in the width direction.

[0024] Specifically, the central cylinder 1 is used to hold and screen tailings slurry, and its specific driving method and working principle will not be elaborated here.

[0025] Furthermore, the outline of the slip ring conductive rail cylinder 3 is adapted to the outer outline of the central cylinder 1. In the actual installation process, the slip ring conductive rail cylinder 3 needs to be wrapped around the outer wall of the central cylinder 1 and fixedly connected to the central cylinder 1. When the central cylinder 1 rotates, the slip ring conductive rail cylinder 3 and the central cylinder 1 move concentrically.

[0026] In this embodiment, six sets of carbon brush 521 adjustment components 5 are provided, with three sets of carbon brush 521 adjustment components 5 forming a module. Two modules are symmetrically arranged at both ends of the centerline of the fixed plate 4 about the width direction of the fixed plate 4. This allows the six sets of carbon brush 521 adjustment components 5 to work together to positively guide the adaptation capability of the drive power supply adjustment device when the slip ring conductive rail cylinder 3 and the carbon brush 521 adjustment components 5 move relative to each other.

[0027] It should be noted that in this embodiment, the components of the six sets of carbon brush 521 adjustment assemblies 5 are the same and the way they cooperate with the fixed plate 4 is the same, and the functions of the six sets of carbon brush 521 adjustment assemblies 5 are the same. For ease of explanation, the following description will focus on the cooperation between one set of carbon brush 521 adjustment assemblies 5 and the fixed plate 4 and the slip ring conductive rail cylinder 3.

[0028] Reference Figure 2 and Figure 4The carbon brush 521 adjustment assembly 5 includes a support arm connecting seat 51, a carbon brush movable seat 52, and a movable connector 53. The support arm connecting seat 51 is disposed on the fixed plate 4. The support arm connecting seat 51 and the carbon brush movable seat 52 are movably connected through the movable connector 53. The carbon brush 521 is movably connected to the carbon brush movable seat 52. When relative movement occurs between the carbon brush 521 and the slip ring conductive rail cylinder 3, the carbon brush movable seat 52 carries the carbon brush 521 and swings along the support arm connecting seat 51 through the movable connector 53. The carbon brush 521 is always in contact with the surface of the slip ring conductive rail cylinder 3.

[0029] Specifically, refer to Figure 3 The support frame 2 includes a base 21 and a support rod 22. The support rod 22 is set perpendicular to the surface of the base 21 in terms of spatial position. By changing the position of the base 21, the relative position between the support rod 22 and the slip ring conductive rail cylinder 3 can be adjusted.

[0030] Furthermore, a locking buckle 8 is detachably provided on the fixing plate 4. The fixing plate 4 is locked to the support frame 2 by the locking buckle 8. The contour formed by the locking buckle 8 is adapted to the outer contour of the support rod 22. At the same time, the locking buckle 8 is made of a material with recoverable elastic deformation (such as steel sheet). The locking buckle 8 is fixed to the fixing plate 4 by bolts. After the position of the fixing plate 4 along the height direction of the support rod 22 is adjusted, the fixing plate 4 can be stably fixed to the support rod 22 by tightening the bolts. The operation is simple.

[0031] Correspondingly, a fixing hole 41 is provided on the fixing plate 4, and a locking screw 411 is threaded into the fixing hole 41. The two end faces of the support arm connecting seat 51 along the height direction are provided with through holes 511. The diameter of the through hole 511 and the diameter of the locking screw 411 are in clearance fit, so that the support arm connecting seat 51 can rotate axially along the locking screw 411. In the actual installation process, the locking screw 411 is first inserted into the fixing hole 41, and the support arm connecting seat 51 is inserted into the locking screw 411 through the through hole 511. Then, a nut is used to engage with the threaded section of the locking screw 411.

[0032] It should be briefly described here that the locking screw 411 consists of a screw head, a connecting rod, and a threaded section. The screw head, connecting rod, and threaded section are integrally formed and are conventional fixing components in the mechanical field. Their specific shapes will not be described in detail here.

[0033] Furthermore, the connector 53 includes a first connecting arm 531 and a second connecting arm 532. One end of the first connecting arm 531 and one end of the second connecting arm 532 are movably connected to the fixing plate 4, and the other end of the first connecting arm 531 and the other end of the second connecting arm 532 are movably connected to the carbon brush movable seat 52.

[0034] The carbon brush holder 52 has movable holes 522 through its two end faces along its length. A movable shaft 5221 is inserted into the movable holes 522. The diameter of the movable shaft 5221 and the movable hole 522 are in clearance fit, so that the movable shaft 5221 can rotate along the movable hole 522.

[0035] Correspondingly, one end of the movable shaft 5221 is integrally formed with a bent portion 52211. After the movable shaft 5221 is inserted into the movable hole 522, a force can be applied to the bent portion 52211, thereby deforming the bent portion 52211 to limit the range of motion of the movable shaft 5221 along the movable hole 522.

[0036] Meanwhile, a rotating shaft 52212 is movably connected to one end of the movable shaft 5221 away from the bending part 52211. A mounting seat 9 is rotatably connected to the rotating shaft 52212. The mounting seat 9 is used to install the carbon brush 521 so as to facilitate the replacement or maintenance of the carbon brush 521. Since the mounting seat 9 and the rotating shaft 52212 are in a rotatable connection state, the mounting seat 9 can rotate axially along the rotating shaft 52212.

[0037] Reference Figure 4 Both ends of the first connecting arm 531 and the second connecting arm 532 along the length direction are provided with rivet holes 10. Correspondingly, the carbon brush movable seat 52 and the support arm connecting seat 51 are provided with rivet holes 10. Thus, both ends of the first connecting arm 531 and the second connecting arm 532 along the length direction can be riveted to achieve movable connection with the carbon brush movable seat 52 and the support arm connecting seat 51.

[0038] At the same time, refer to Figure 1 or Figure 2 The slip ring conductive rail cylinder 3 has the same number of slip ring conductive rails 6 as the carbon brush 521 adjustment components 5. In this embodiment, since there are six sets of carbon brush 521 adjustment components 5, and every three sets of carbon brush 521 adjustment components 5 form a module, there are three slip ring conductive rails 6. The three slip ring conductive rails 6 are evenly distributed along the height direction of the outer wall of the slip ring conductive rail cylinder 3, and the slip ring conductive rails 6 are circumferentially formed along the outer wall of the slip ring conductive rail cylinder 3. Thus, two sets of carbon brush 521 adjustment components 5 slide within each slip ring conductive rail 6.

[0039] Correspondingly, the width tolerance of the slip ring conductive rail 6 and the width tolerance of the carbon brush 521 are in the form of a clearance fit. Through the guiding effect of the slip ring conductive rail 6, the sliding path of the carbon brush 521 along the slip ring conductive rail cylinder 3 is limited, reducing the probability that the carbon brush 521 will change its movement path along the slip ring conductive rail cylinder 3 due to the wobbling caused by the rotation of the slip ring conductive rail cylinder 3.

[0040] An adjusting spring 7 is connected between the end of the first connecting arm 531 that is connected to the fixing plate 4 and the end of the second connecting arm 532 that is connected to the carbon brush movable seat 52.

[0041] On the other hand, the slip ring conductive rail cylinder 3 is provided with a terminal 31, and the carbon brush 521 is provided with a connecting wire 5211. The carbon brush 521 is electrically connected to the slip ring conductive rail cylinder 3 through the connecting wire 5211.

[0042] The top of the slip ring conductive rail cylinder 3 rotatably supports a rotating ring 11 (for example, the rotating ring 11 and the slip ring conductive rail cylinder 3 are rotatably connected through a bearing). The terminal 31 is installed on the rotating ring 11. Thus, when the slip ring conductive rail cylinder 3 and the carbon brush 521 rotate relative to each other, the rotating ring 11 and the slip ring conductive rail cylinder 3 are in a state of relative rotation, and the terminal 31 on the rotating ring 11 is electrically connected to the connecting wire 5211. This makes the carbon brush 521 and the rotating ring 11 relatively stationary while the slip ring conductive rail cylinder 3 rotates relative to each other. This reduces the probability of the connecting wire 5211 getting tangled when it is electrically connected to the terminal 31.

[0043] Therefore, the implementation principle of the large-angle, large-range adaptive drive power supply adjustment device in this application embodiment is as follows: when relative rotation occurs between the slip ring conductive rail cylinder 3 and the carbon brush 521, the carbon brush movable seat 52 and the support arm connecting seat 51 are movably connected through the proposed connecting arm and the second connecting arm 532, thereby causing the movable shaft 5221 on the carbon brush movable seat 52 to carry the mounting seat 9 on which the carbon brush 521 is mounted to rotate along the rotating shaft 52212. The carbon brush movable seat 52 carries the carbon brush 521 through the movable connecting member 53. The carbon brush 521 swings along the support arm connecting seat 51, so that the carbon brush 521 and the slip ring conductive rail cylinder 3 are in a soft connection state. This reduces the probability that the carbon brush 521 will not be able to abut against a part of the slip ring conductive rail cylinder 3 due to the change of its rotation axis when the slip ring conductive rail cylinder 3 is in operation, or that the contact force between the carbon brush 521 and a part of the surface of the slip ring conductive rail cylinder 3 is too large, thereby causing the carbon brush 521 or the carbon brush movable seat 52 to bear too much force, resulting in damage to the carbon brush 521 and / or the carbon brush movable seat 52.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
