Description

Technical Field

[0001] The invention relates to a current collecting and installing structure of a concentrator, belonging to the technical field of mineral processing equipment. Background Art

[0002] Concentrators are key equipment widely used in industries such as mining, metallurgy, and chemicals, primarily for solid-liquid separation. The concentrator's current collector, a core electrical component, provides a stable power supply to the electrical control system and travel mechanism on the bridge.

[0003] Currently, the most common current collector uses a conductive ring mounted around the top of a central feed tube. Carbon brushes and a brush holder are fixed to an outer housing and rotate with the bridge. External power is connected to the current collector through a central feed tube and then to the electrical system on the bridge. The conductive ring, brush holder, and brushes are arranged vertically to ensure continuous power transmission.

[0004] However, since the concentrator is often in a harsh working environment with high dust and high humidity, dust is easily attached to the inside of the conductive ring of the collector during actual operation, resulting in poor contact between the carbon brush and the conductive ring, causing unstable power transmission and even equipment shutdown. At the same time, the carbon brush is prone to getting stuck or falling off during the circular motion, posing hidden dangers to equipment operation and affecting production efficiency. Therefore, improvements are urgently needed. Summary of the Invention

[0012] Furthermore, the end of the rotating block away from the conductive ring is connected to a socket block slidably mounted on the socket shaft, and the side surface of the socket block is symmetrically fixedly connected with two extension rods, and the free ends of the two extension rods are vertically fixedly connected with push rods, and a push plate is fixedly connected between the two push rods, and the push plate is arranged on the side of the fixed plate close to the concentrator feed barrel, and the push plate is fixedly connected to the side of the push plate close to the concentrator feed barrel with a push block, and a trigger button is provided on the side wall of the concentrator feed barrel to cooperate with the push block and to prompt the conductive ring to vibrate.

[0017] 2. In the present invention, while the gear transmission assembly is transmitting, the drive shaft will drive the swing arm to swing. The swing of the swing arm will make the nozzle of the nozzle closer to the conductive ring, and the swing of the nozzle head can make the nozzle of the nozzle align with the conductive ring. Then, through the swing of the swing arm and the nozzle head, the nozzle head can better spray the conductive ring and can adapt to the spraying of conductive rings at different angles and positions, with stronger adaptability.

[0018] 3. The present invention can absorb vibration energy through the setting of the shock-absorbing mechanism, ensure uniform contact pressure between the carbon brush and the conductive ring, and avoid poor contact or arc discharge caused by vibration. At the same time, through the design of the spiral push groove and the push assembly, in conjunction with the angle sensor and the trigger button, multi-level monitoring of vibration is achieved, and different levels of alarms can be issued according to the vibration amplitude. It can not only remind maintenance when there is slight looseness, but also prompt the staff to stop the machine for maintenance in time when there is severe vibration, thereby effectively preventing equipment damage and safety accidents, ensuring the overall shock absorption effect, and facilitating maintenance and replacement.

DETAILED DESCRIPTION

[0021] The present invention will be described in more detail below with reference to the embodiments.

[0022] Example 1 See also Figures 1 to 6 The concentrator current collector installation structure of this embodiment includes a conductive ring 6 sleeved on the concentrator feed barrel 1 and a current collector carbon brush 3 slidably installed on the conductive ring 6.

[0023] In this embodiment, the conductive ring 6 is fixedly sleeved on the outside of the concentrator feed barrel 1 by five fixing brackets 7 arranged circumferentially along the outer wall of the concentrator feed barrel 1. The five fixing brackets 7 are evenly spaced along the circumference, so that the force is more uniform.

[0024] See also Figure 2 Four annular isolation grooves 601 are arranged in sequence from top to bottom on the side of the conductive ring 6 away from the concentrator feed barrel 1. Two current collector carbon brushes 3 are provided. The two current collector carbon brushes 3 realize redundant design to avoid the accidental situation of equipment shutdown caused by damage to a single current collector carbon brush 3.

[0025] Each current collector carbon brush 3 includes four carbon brush units, which are slidably mounted in four annular isolation grooves 601 in a one-to-one correspondence. The design of multiple annular isolation grooves 601 can prevent current short circuits, disperse contact pressure, and reduce wear.

[0026] A current collector buckle 8 is installed between the two current collector carbon brushes 3. The current collector buckle 8 is connected to the concentrator bridge and rotates around the concentrator feed barrel 1 with the concentrator bridge. During the rotation of the concentrator bridge around the concentrator feed barrel 1, the current collector carbon brush 3 always maintains contact with the conductive ring 6.

[0027] At the same time, the two collector carbon brushes 3 are electrically connected to the external distribution box.

[0028] In this embodiment, the conductive ring 6 is fixed to the outer wall of the concentrator feed barrel 1 through five evenly distributed fixing brackets 7 to form a stable annular power supply track. The collector buckle 8 fixes the two collector carbon brushes 3 on the concentrator bridge. When the concentrator bridge is energized through the distribution box and rotates around the concentrator feed barrel 1, the collector carbon brushes 3 also slide along the annular isolation groove 601 of the conductive ring 6, thereby realizing a stable power supply process.

[0029] From the above description, it can be seen that the beneficial effect of the present invention is that by setting the annular isolation groove 601 on the outside of the conductive ring 6, compared with the existing design in which the sliding surface of the conductive ring is directly set at the top, the dust in the working environment is less likely to fall into the annular isolation groove 601, thereby effectively avoiding poor contact caused by dust and improving the operation rate of the equipment. At the same time, by installing the collector carbon brush 3 on the outside of the conductive ring 6, when the collector carbon brush 3 moves with the concentrator bridge, the direction of the collector carbon brush 3 is consistent with the movement direction of the collector carbon brush 3, and there is no need to adjust the installation angle of the collector carbon brush 3. The movement stability of the collector carbon brush 3 is better. At the same time, through the horizontal arrangement of the collector carbon brush 3 and the conductive ring 6, the contact pressure between the collector carbon brush 3 and the conductive ring 6 can be reduced, thereby extending the life of the equipment.

[0030] Furthermore, the current collector buckle 8 includes a mounting bracket 2 and two buckle assemblies, and the two buckle assemblies are respectively mounted on ends of the two current collector carbon brushes 3 that are close to each other.

[0031] Specifically, the buckle assembly includes a buckle plate 4 and a U-shaped buckle 5 .

[0032] In this embodiment, the snap plate 4 is fixed to the current collector carbon brush 3 by four bolts.

[0033] The mounting bracket 2 includes a fixing rod 202 and connecting rods 201 fixed at both ends of the fixing rod 202 . The free end of the connecting rod 201 is locked and fixed on the snap plate 4 through a U-shaped snap 5 .

[0034] In this embodiment, both ends of the U-shaped clip 5 are threadedly connected with locking bolts, and the U-shaped clip 5 is locked and fixed on the clip plate 4 by the locking bolts, and then the U-shaped clip 5 can lock and fix the connecting rod 201.

[0035] The fixing rod 202 is used to connect the concentrator bridge.

[0036] Example 2 See also Figures 7 to 10On the basis of the above-mentioned embodiment 1, the concentrator collector installation structure of this embodiment has a blowing mechanism 10 installed on the collector buckle 8. The blowing mechanism 10 is set to blow toward the conductive ring 6, thereby further preventing dust in the environment from entering the conductive ring 6 and avoiding affecting the movement of the collector carbon brush 3.

[0037] Specifically, the blowing mechanism 10 includes a nozzle 21 and an adjustment component. The nozzle 21 is connected to an external air supply system, and air is supplied to the nozzle 21 through the air supply system, and then blown toward the conductive ring 6 by the nozzle 21. In this embodiment, the air supply system transmits 0.2~0.6MPa clean compressed air to the nozzle 21.

[0038] See also Figure 9 and Figure 10 In order to enable the nozzle 21 to better align with the conductive ring 6 for blowing, an adjustment component is also provided in this embodiment.

[0039] Specifically, the adjustment component includes a connection box 11, the top of the connection box 11 is rotatably connected to a drive shaft 13, and a motor for driving the drive shaft 13 to rotate is provided inside the connection box 11, and the motor is externally connected to a distribution box.

[0040] The top of the drive shaft 13 is vertically fixedly sleeved with a swing rod 14, and the free end of the swing rod 14 is vertically rotatably sleeved with a steering shaft 20. The jet head 21 is fixedly mounted on the top of the steering shaft 20, and the drive shaft 13 drives the steering shaft 20 to rotate through the gear transmission assembly.

[0041] The gear transmission assembly includes a first bevel gear 12 , a second bevel gear 17 , a third bevel gear 18 and a fourth bevel gear 19 .

[0042] The first bevel gear 12 is fixedly sleeved on the drive shaft 13 .

[0043] The fourth bevel gear 19 is fixedly sleeved on the steering shaft 20 .

[0044] A rotating shaft 16 is fixedly sleeved between the second bevel gear 17 and the third bevel gear 18 , and the rotating shaft 16 is rotatably mounted on the bottom end of the swing rod 14 .

[0045] The first bevel gear 12 is meshed with the second bevel gear 17 , and the third bevel gear 18 is meshed with the fourth bevel gear 19 .

[0046] From the above description, it can be seen that when the motor drives the drive shaft 13 to rotate, the drive shaft 13 can drive the first bevel gear 12 to rotate. When the first bevel gear 12 rotates, it can drive the second bevel gear 17 to rotate, and then the second bevel gear 17 can drive the third bevel gear 18 to rotate through the rotating shaft 16. Since the third bevel gear 18 and the fourth bevel gear 19 are meshed, the fourth bevel gear 19 will also rotate synchronously.

[0047] The rotation of the fourth bevel gear 19 can drive the steering shaft 20 to rotate, and the steering shaft 20 can then drive the jet head 21 to swing.

[0048] While the gear transmission assembly is transmitting, the drive shaft 13 will drive the swing rod 14 to swing. The swing of the swing rod 14 will make the nozzle of the nozzle 21 closer to the conductive ring 6, and the swing of the nozzle 21 can make the nozzle of the nozzle 21 align with the conductive ring 6. Then, through the swing of the swing rod 14 and the nozzle 21, the nozzle 21 can better spray the conductive ring 6, and can adapt to the spraying of the conductive ring 6 at different angles and positions, and has stronger adaptability.

[0049] Furthermore, two connecting plates 15 are fixed at intervals along the length direction at the bottom end of the swing rod 14 , and the rotating shaft 16 rotates through each connecting plate 15 . The setting of the connecting plates 15 can ensure the rotation stability of the rotating shaft 16 .

[0050] Example 3 See also Figures 11 to 15 The concentrator collector installation structure of this embodiment is based on the above-mentioned embodiment 1 or embodiment 2. A plurality of shock-absorbing mechanisms 22 are installed between the conductive ring 6 and the concentrator feed barrel 1. Since the collector carbon brush 3 inevitably causes the conductive ring 6 to vibrate during its rotation around the conductive ring 6, by installing the shock-absorbing mechanism 22 between the conductive ring 6 and the concentrator feed barrel 1, when the conductive ring 6 vibrates, the shock-absorbing mechanism 22 can absorb the vibration energy through elastic deformation, thereby ensuring uniform contact pressure between the carbon brush unit and the conductive ring 6 and improving operational stability.

[0051] The plurality of shock absorbing mechanisms 22 are evenly arranged along the circumferential direction. In this embodiment, a shock absorbing mechanism 22 is provided between any two adjacent fixing brackets 7. The evenly distributed shock absorbing mechanisms 22 can better absorb vibration.

[0052] Specifically, see Figures 12 to 15 The shock absorbing mechanism 22 includes a dial block 24 arranged at the end thereof which is fitted into the inner side of the conductive ring 6. The end of the dial block 24 away from the conductive ring 6 is slidably sleeved with a sleeve shaft 27. The free end of the sleeve shaft 27 is fixedly connected with a fixed plate 33. One end of the fixed plate 33 is bent and fixedly connected to the concentrator feed barrel 1. A return spring 28 sleeved outside the sleeve shaft 27 is fixedly connected between the fixed plate 33 and the dial block 24.

[0053] When the conductive ring 6 vibrates, the vibration will be transmitted to the dial block 24. Since the dial block 24 and the sleeve shaft 27 are slidably connected, the dial block 24 will move toward the fixed plate 33, thereby compressing the return spring 28 and deforming it. The deformation of the return spring 28 can absorb the vibration, achieve energy consumption, and avoid large-scale vibration.

[0054] Furthermore, in order to constantly monitor the vibration amplitude of the conductive ring 6 , the end of the dial block 24 away from the conductive ring 6 is connected to a sleeve block 2901 slidably sleeved on the sleeve shaft 27 , wherein the sleeve block 2901 is rotationally connected to the dial block 24 .

[0055] Two extension rods 29 are symmetrically fixedly connected to the side of the socket block 2901, and the free ends of the two extension rods 29 are vertically fixedly connected to push rods 30. A push plate 31 is fixedly connected between the two push rods 30, and the push plate 31 is arranged on the side of the fixed plate 33 close to the concentrator feed barrel 1. A push block 32 is fixedly connected to the side of the push plate 31 close to the concentrator feed barrel 1, and a trigger button 23 is provided on the side wall of the concentrator feed barrel 1 to cooperate with the push block 32 and to prompt the conductive ring 6 to vibrate.

[0056] In this embodiment, the trigger button 23 is electrically connected to the host computer. At the same time, the host computer is connected to an audible and visual alarm. When the trigger button 23 is pressed, the audible and visual alarm is activated.

[0057] Specifically, when the vibration amplitude of the conductive ring 6 is large, the dial block 24 is squeezed and the sliding amplitude will also become larger, and when the dial block 24 is squeezed and slides, the extension rod 29, the push rod 30, the push plate 31 and the push block 32 will all move synchronously toward the side of the concentrator feed barrel 1, and then the push block 32 will press the trigger button 23, and the sound and light alarm will be activated, prompting nearby staff that the vibration amplitude of the conductive ring 6 is too large and needs to be inspected and fixed in time.

[0058] Furthermore, in order to more accurately monitor the vibration amplitude of the conductive ring 6, please refer to Figure 13 and Figure 14 Two spiral push grooves 2401 are provided on the side wall of the rotating block 24 and are centrally symmetrically arranged.

[0059] Both ends of the two spiral push grooves 2401 are connected through a return groove 2402 arranged parallel to the axis of the dial block 24, thereby forming a closed loop structure of the first spiral push groove 2401-first return groove 2402-second spiral push groove 2401-second return groove 2402.

[0060] In particular, the return groove 2402 is recessed inwardly at one end away from the conductive ring 6 to form a concave groove, and the depth of the concave groove is greater than the depth of the return groove 2402 , thereby forming a height difference.

[0061] The end of the spiral push groove 2401 that is connected to the concave groove has the same depth as the concave groove. During the spiral process of the spiral push groove 2401 spiraling toward the conductive ring 6, the depth of the spiral push groove 2401 gradually decreases, and finally becomes the same depth as the end of the return groove 2402 close to the conductive ring 6 and is connected.

[0062] One end of the return groove 2402 away from the conductive ring 6 is provided with a pushing assembly for rotating the dial block 24 when the dial block 24 slides along the sleeve shaft 27. An angle sensor is also provided inside the dial block 24, and the angle sensor is externally connected to the host computer.

[0063] Specifically, see Figure 15 The pushing assembly includes a rotating frame 26, a push rod 2601 movably mounted on the end of the rotating frame 26, and a rolling ball 2603 movably mounted on the end of the push rod 2601.

[0064] Among them, a compression spring 2602 is fixedly connected between the inner end of the push rod 2601 and the inner end of the socket hole at the end of the dial frame 26. The compression spring 2602 always maintains a compression tendency, so that the push rod 2601 always maintains a tendency to extend outward. The ball 2603 is movably clamped in the return groove 2402 and is always kept clamped in the return groove 2402 by the thrust of the push rod 2601. Specifically, when the conductive ring 6 does not vibrate and the dial block 24 is not squeezed, the ball 2603 is clamped in the concave groove.

[0065] When the conductive ring 6 vibrates, it will push the dial block 24 to move. Due to the setting of the top rod 2601 and the ball 2603, when the dial block 24 moves, due to the height difference between the concave groove and the return groove 2402, the ball 2603 will only move along the spiral push groove 2401, thereby causing the dial block 24 to rotate.

[0066] In particular, when the vibration amplitude of the conductive ring 6 is too large, the ball 2603 moves along the spiral push groove 2401, driving the dial block 24 to rotate. When the dial block 24 rotates 90°, the angle sensor detects the large rotation of the dial block 24, and then the upper computer controls the sound and light alarm to issue a continuous alarm, prompting the staff to stop the machine for maintenance and fix the conductive ring 6.

[0067] At the same time, when the dial block 24 rotates 90°, the ball 2603 will enter another return groove 2402. Due to the return action of the return spring 28, the return end of the dial block 24 continues to fit the conductive ring 6, and the ball 2603 will enter another concave groove, thereby completing a movement.

[0068] If the vibration amplitude of the conductive ring 6 is too large and the dial block 24 is pushed to slide, the ball 2603 will move in the spiral push groove 2401 and the return groove 2402, and the cycle will continue.

[0069] In this embodiment, when the trigger button 23 is triggered, the sound and light alarm will be triggered intermittently, prompting the staff that the conductive ring 6 is loose to a certain extent.

[0070] If the dial block 24 rotates 90°, the angle sensor detects a large rotation of the dial block 24, and the sound and light alarm will be continuously triggered, indicating that the vibration amplitude of the conductive ring 6 is too large, and the staff needs to stop the machine immediately for maintenance to avoid safety risks.

[0071] The free end of the rotating frame 26 is bent and fixedly mounted on the concentrator feed barrel 1 .

[0072] From the above description, it can be seen that the setting of the shock-absorbing mechanism 22 can absorb vibration energy, ensure uniform contact pressure between the carbon brush and the conductive ring 6, and avoid poor contact or arc discharge caused by vibration. At the same time, through the design of the spiral push groove 2401 and the push assembly, in conjunction with the angle sensor and the trigger button 23, multi-level monitoring of vibration is achieved, and different levels of alarms can be issued according to the vibration amplitude. It can not only remind maintenance when there is slight looseness, but also remind staff to stop maintenance in time when there is severe vibration, thereby effectively preventing equipment damage and safety accidents, ensuring the overall shock absorption effect, and facilitating maintenance and replacement.
