Description

Technical Field

[0001] The present invention relates to the field of workpiece polishing, and particularly to a polishing device for a traction wheel of a mine hoist. Background Art

[0002] As a core device in mine production, the surface quality of the traction wheel of a mine hoist directly affects the operation efficiency, safety and service life of the device; the polishing of the outer ring of the side of the traction wheel mainly relies on manual grinding or simple mechanical devices, which has problems such as low efficiency, poor precision and difficulty in ensuring surface consistency. Especially for the traction wheel of a multi-rope friction hoist, the traditional process is difficult to meet the high-precision processing requirements, and the polishing effect of the traction wheel is poor.

[0003] For example, a polishing device for the outer ring of a bearing provided in the authorized announcement number CN107953160B. When it is necessary to polish the outer ring of the bearing, the outer ring of the bearing can be sleeved outside the fixed block, and then the air cylinder is started. The air cylinder drives the runner to press down, and the runner drives the pressing rod to press down. After the lower end of the pressing rod touches the outer wall of the fixed block, the pressing rod rotates along the length direction of the installation groove. At this time, the tension spring is stretched, and the tension spring provides a pulling force for the pressing rod so that the lower end of the pressing rod abuts against the side of the fixed block. The lower end of the pressing rod presses the upper part of the outer ring of the bearing. Then, the adjusting bolt on the sliding device is rotated. The adjusting bolt is in threaded cooperation with the installation block so that the square slider slides along the length direction of the square chute. The direction slider drives the telescopic rod to move up and down until the grinding block at the left end of the telescopic rod is flush with the outer ring of the bearing. The spring outside the telescopic rod gives the grinding block an elastic force so that the grinding block presses tightly against the side of the outer ring of the bearing. Then, the motor and the water pump are started. The motor drives the fixed block to rotate through the belt, and the fixed block drives the outer ring of the bearing to rotate. Since the runner is rotatable, the pressing rod also rotates with the outer ring of the bearing. The grinding block and the outer ring of the bearing have a sliding friction, so that the grinding block polishes the outer ring of the bearing.

[0004] It has great drawbacks: during the use process, when the outer ring of the bearing is sleeved on the fixed block, since the outer ring of the bearing is a cylinder with a through hole up and down and the fixed block is conical, the lower end of the outer ring of the bearing will fit with the fixed block, but there will be a gap between the upper part of the outer ring of the bearing and the fixed block. When the pressing rod descends along the fixed block, it will insert into the gap between the outer ring of the bearing and the fixed block, resulting in a reduction in the fixing effect and tilting the outer ring of the bearing; at the same time, when the outer ring of the bearing is sleeved, the axis of the outer ring of the bearing and the axis of the fixed block are not on the same straight line, which will also cause the outer ring of the bearing to tilt.

[0016] The beneficial effects of the present invention are as follows: firstly, the structure that abuts against the traction wheel is changed into a freely retractable structure and the lower end is changed into a pressure plate structure, so that when the structure slides along the sleeve block, the lower end is prevented from entering into the gap between the traction wheel and the sleeve block, thereby causing the traction wheel to tilt as a whole, so that the fixing effect of the traction wheel as a whole is reduced; thereby reducing the problem of uneven polishing caused by uneven pressing force, and significantly improving the polishing quality; Secondly, the fixing stability is improved. Sand is filled in the sleeve block so that it can be deformed when pressed by the pressure plate and fit more closely to the inner ring of the traction wheel, thereby significantly improving the fixing stability of the traction wheel, reducing the shaking during polishing, ensuring the polishing accuracy, and adapting to traction wheels of different sizes. The adjustable support platform is improved through the adjustable telescopic rod 2 and the sliding table. The position of the placement table is adjusted for traction wheels of different sizes to ensure that the lower part of the traction wheel inner ring can fit closely to the sleeve block, thereby adapting to the polishing needs of traction wheels of various specifications and improving the versatility and flexibility of the device; a limit rod and a ball are added under the polishing block. The ball enters the slide groove and plays a precise limiting role during the polishing process, which effectively prevents the polishing block from deviating during rotating polishing, thereby significantly improving the polishing accuracy and stability and ensuring the polishing quality; Thirdly, the industrial camera can detect the axis position of the traction wheel in real time, ensuring that the traction wheel always maintains the correct position before polishing, thereby significantly improving the polishing accuracy and reducing the uneven polishing or scrap rate caused by position offset; the airbag expansion can be accurately controlled to achieve fine adjustment and enhance adaptability. By adjusting the output of the air pump, the airbag expansion can be finely controlled to fine-tune the position of the traction wheel; multiple balls are connected to the upper surface of the placement table for rotation. The presence of the balls significantly reduces the friction between the traction wheel and the placement table, allowing the traction wheel to move to the target position more easily and smoothly, which not only improves the convenience of the operator, but also improves the efficiency of position adjustment, thereby improving the efficiency of the overall polishing operation; Fourthly, the introduction of the water injection film can fill the gap between the sleeved block and the contact surface of the traction wheel, and the hardness of the contact surface between the sleeved block and the traction wheel is increased by injecting water through the water pump, effectively resisting the pressing force of the polishing block on the traction wheel, fundamentally solving the problem of traction wheel displacement caused by the deformation of the sleeved block, which ensures that the polishing block and the traction wheel always maintain a tight and stable contact, thus achieving more precise polishing, significantly improving the polishing accuracy and product quality, and reducing the uneven polishing or waste products caused by position deviation; the increase in the hardness of the sleeved block makes the entire polishing system more stable, and the polishing block can continuously and stably polish the traction wheel, reducing the polishing interruption or speed fluctuation caused by position adjustment, thereby improving the polishing efficiency, and the stable polishing process also helps to extend the service life of the polishing block and the equipment; the water pump and the water injection film achieve precise control of the water injection volume, and the operator can adjust the water injection volume of the water pump according to the actual polishing requirements, thereby precisely adjusting the hardness of the sleeved block. This adjustability enables the polishing device to adapt to the polishing requirements of traction wheels of different materials and different sizes, further optimizing the polishing effect and improving the adaptability and flexibility of the equipment.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0022] Example 1: As Figures 1 - 5As shown in the figure, a polishing device for a traction wheel used in a mine hoist according to the present application includes a polishing assembly 100, and the polishing assembly 100 includes a protective shell 110, a polishing member 130, a fixing member 140, a positioning member 160, a water spraying member 170 and a pressing member 180; The polishing assembly 100 includes a protective shell 110. The protective shell 110 is a cylindrical shape with an open upper end. The lower end of the protective shell 110 is provided with a water drainage hole 111 for discharging cooling water. A water tank 150 is fixed under the protective shell 110. A communication hole 151 is fixed on the water tank 150. The communication hole 151 is communicated with the water drainage hole 111. The water tank 150 is used for storing cooling water. There are multiple water drainage holes 111 and communication holes 151, and they correspond to each other one by one. A cover plate 120 is rotatably connected to the protective shell 110. The cover plate 120 is made of magnetic material. An electromagnet 112 is fixed at the upper end of the protective shell 110. The electromagnet 112 adsorbs the cover plate 120 when energized.

[0023] Specifically, when the traction wheel needs to be polished, the cover plate 120 is rotated manually or by an external force. The traction wheel is hoisted into the protective shell 110 by a hoisting structure. After the traction wheel is placed and the cover plate 120 is reset, the electromagnet 112 is energized to adsorb the cover plate 120 to fix the position of the cover plate 120.

[0024] The polishing member 130 includes a bearing 131. The inner ring of the bearing 131 is fixed on the inner bottom side of the protective shell 110. The outer ring of the bearing 131 is provided with teeth. A motor 138 is provided under the protective shell 110. The output end of the motor 138 is fixed with a gear. The gear is located inside the protective shell 110 and meshes with the teeth on the outer ring of the bearing 131. When the motor 138 works, it drives the gear and the outer ring of the bearing 131 to rotate. A vertical plate 132 is fixed on the outer ring of the bearing 131. An electric sliding table 133 is fixed on one side of the vertical plate 132. A telescopic rod 134 is fixed on the slider of the electric sliding table 133. The output end of the telescopic rod 134 is detachably provided with a polishing block 135. The electric sliding table 133 is used to adjust the height of the polishing block 135. When the telescopic rod 134 extends and retracts, it adjusts the distance between the polishing block 135 and the traction wheel.

[0025] Specifically, when polishing the outer ring of the traction wheel, the height of the polishing block 135 is adjusted by the electric sliding table 133 according to the height of the traction wheel. When the length of the telescopic rod 134 extends, it drives the polishing block 135 to move so that the polishing block 135 is close to the traction wheel. After long-term use, the polishing block 135 can be disassembled and replaced. The outer ring of the traction wheel is polished by driving the gear and the outer ring of the bearing 131 to rotate by the motor 138.

[0026] The fixing member 140 includes a fixing block 141; The fixing block 141 is fixed to the inner bottom side of the protective housing 110; The sleeving block 161 is frustum-shaped. The lower end of the sleeving block 161 is fixed to the fixing block 141, and the traction wheel to be polished is sleeved on the sleeving block 161.

[0027] Specifically, the fixing member 140 supports the sleeving block 161, and the hoisted traction wheel is sleeved on the sleeving block 161.

[0028] It further includes a water spraying member 170. The water spraying member 170 includes a third telescopic rod 171. The third telescopic rod 171 is fixed to the top side of the cover plate 120. The lower end of the third telescopic rod 171 is fixed to a spraying frame 172. The spraying frame 172 is annular, and the lower end of the spraying frame 172 is provided with a water spraying port; The spraying frame 172 is provided with a water supply pipe 173. One end of the water supply pipe 173 penetrates through the cover plate 120 and is connected to a water inlet pump. The water supply pipe 173 is of a telescopic pipe structure.

[0029] Specifically, the third telescopic rod 171 can adjust the water spraying height. When the water inlet pump at one end of the water supply pipe 173 works, the water spraying port below the spraying frame 172 sprays water towards the traction wheel and the polishing block 135 for cooling.

[0030] Specifically, the sprayed cooling water enters the water tank 150 through the water outlet hole and the communication hole 151 for storage. The stored cooling water can be used again for cooling the traction wheel and the polishing block 135 after being filtered again; after long-term use, the cooling water remaining in the protective housing 110 is cleaned manually.

[0031] The pressing member 180 includes a fourth telescopic rod 181. The upper end of the fourth telescopic rod 181 is fixed to the cover plate 120. There are multiple fourth telescopic rods 181, and the lower end of the fourth telescopic rod 181 is fixed to a pressing plate 182; Both the fourth telescopic rod 181 and the pressing plate 182 are located inside the annular spraying frame 172; The fourth telescopic rod 181 is used to adjust the height position of the pressing plate 182. When the fourth telescopic rod 181 drives the pressing plate 182 to descend, it presses the traction wheel to be detected.

[0032] Specifically, after the traction wheel is hoisted onto the sleeving block 161 and the position of the cover plate 120 is fixed, the fourth telescopic rod 181 drives the pressing plate 182 to descend to press the traction wheel to fix the position of the traction wheel; after polishing is completed, the pressing plate 182 rises and resets, the cover plate 120 is opened, and the polished traction wheel is hoisted out through the hoisting structure.

[0033] The technical solutions in the above embodiments of the present application at least have the following technical effects or advantages: Change the structure of the interfering traction wheel to be freely telescopic and the lower end to be the pressing plate 182 structure, avoiding the lower end entering the gap between the traction wheel and the sleeve block 161 when it slides along the sleeve block 161, thus causing the overall traction wheel to tilt, reducing the fixing effect on the overall traction wheel; thereby reducing the problem of uneven polishing caused by uneven pressing force and significantly improving the polishing quality.

[0034] Embodiment 2: When Embodiment 1 is in use, the traction wheel is pressed by the pressing plate 182. However, during the process of placing and sleeving the traction wheel on the sleeve block 161, due to poor accuracy, the traction wheel is in an inclined state on the sleeve block 161. Therefore, the solution of Embodiment 1 is improved as follows Figures 6 - 10 shown: The sleeve block 161 is made of rubber material, with a hollow interior filled with sand, and the sleeve block 161 is in a frustum shape in its initial state; The Shore hardness of the rubber sleeve block 161 is 50A to 70A; The pressing plate 182 is in a cylindrical shape.

[0035] Specifically, when the telescopic rod four 181 drives the pressing plate 182 to descend, it presses the sleeve block 161, and the sleeve block 161 deforms within the inner ring of the traction wheel to fix the position of the traction wheel.

[0036] The fixing block 141 is provided with telescopic rods two 142. There are multiple telescopic rods two 142, and they are evenly distributed at intervals in a ring shape. The upper ends of the telescopic rods two 142 are fixed to the sliding table 143; The telescopic rods two 142 are closely attached to the side of the sleeve block 161, and the telescopic direction of the telescopic rods two 142 is parallel to the generatrix of the sleeve block 161; Specifically, the telescopic rods two 142 are closely attached to the side of the sleeve block 161, which can resist the sleeve block 161 and prevent the sleeve block 161 from collapsing due to the large weight of the sand.

[0037] The telescopic rods two 142 can adjust the position of the sliding table 143 by telescoping; A placement table 166 is provided on the outer circle of the sleeve block 161. The placement table 166 is placed on the sliding table 143, and the placement table 166 is in a cylindrical shape that penetrates up and down; The traction wheel to be polished is placed on the placement table 166; Specifically, according to the size of the traction wheel, the height of the placement table 166 and the sliding table 143 is adjusted so that the lower part of the inner ring of the traction wheel can closely adhere to the sleeve block 161; there are multiple models of the placement table 166, and a suitable size can be selected according to requirements.

[0038] A chute 167 is opened on the side of the placement table 166; A limiting rod 136 is fixed below the polishing block 135. The limiting rod 136 is of a telescopic rod structure, and the output end of the limiting rod 136 is rotatably connected to a ball 137.

[0039] Specifically, when the telescopic rod 134 drives the polishing block 135 to abut against the traction wheel, the ball 137 enters the chute 167, and plays a limiting role when the polishing block 135 rotates around the traction wheel for polishing.

[0040] An electromagnet two 184 is fixed on the lower side surface of the pressing plate 182. The electromagnet two 184 is annular. An iron ring 168 is fixed at the upper end of the sleeved block 161. Specifically, when the height of the pressing plate 182 increases, the electromagnet two 184 is energized to adsorb the iron ring 168, pulling the upper end of the sleeved block 161 to assist the deformed placement table 166 to reset.

[0041] The technical solutions in the above embodiments of the present application at least have the following technical effects or advantages: Improve the fixing stability. The sleeved block 161 is filled with sand, so that it can deform when pressed by the pressing plate 182, and fit more closely to the inner ring of the traction wheel, thus significantly improving the fixing stability of the traction wheel, reducing the shaking during the polishing process, and ensuring the polishing accuracy. Adapt to traction wheels of different sizes. By the adjustable telescopic rod two 142 and the sliding table 143, the adjustable support platform is improved. The position of the placement table 166 is adjusted for traction wheels of different sizes to ensure that the lower part of the inner ring of the traction wheel can closely adhere to the sleeved block 161, thus meeting the polishing requirements of various specifications of traction wheels and improving the versatility and flexibility of the device; A limiting rod 136 and a ball 137 are added below the polishing block 135. The ball 137 enters the chute 167 and plays an accurate limiting role during the polishing process, which effectively prevents the polishing block 135 from shifting during rotary polishing, thus significantly improving the polishing accuracy and stability and ensuring the polishing quality.

[0042] Embodiment 3: When Embodiment 2 is in use, by setting the adjustable placement table 166, the traction wheel can be sleeved on the sleeved block 161 in a horizontal state, and the deformable sleeved block 161 can fix the position of the traction wheel. However, when in use, during the process of placing the traction wheel, when the axis of the traction wheel is not on the same straight line as the sleeved block 161, it will affect the fixing and polishing effects. Therefore, the solution of Embodiment 2 is improved as Figures 11 - 12 shown: An industrial camera 183 is fixed below the pressing plate 182. The industrial camera 183 is located at the center of the annular electromagnet two 184. The industrial camera 183 is used to detect the axis position of the traction wheel.

[0043] An anti-pressure protective cover is fixed on the surface of the industrial camera 183 to prevent the industrial camera 183 from being damaged when pressing the sleeved block 161.

[0044] A fixing airbag 162 is provided inside the sleeved block 161. There are multiple airbags 162, which are evenly distributed in a ring. The upper end of the airbag 162 is fixed to the inner top side of the sleeved block 161, and the lower end of the airbag 162 is fixed to the lower end inside the sleeved block 161. An air pump 164 is fixed inside the fixing block 141. The number of air pumps 164 is the same as the number of airbags 162 and they correspond one by one. The output end of the air pump 164 is communicated with the airbag 162.

[0045] The side of the fixing block 141 is provided with a waterproof and breathable film.

[0046] Specifically, when the industrial camera 183 detects and calculates that the axis position of the traction wheel deviates to one side, by controlling the inflation of the airbag 162 on the other side, the sand inside the sleeved block 161 is resisted, so that the sleeved block 161 resists the traction wheel and the traction wheel is reset.

[0047] A rolling ball is rotatably connected to the upper side surface of the placing table 166. The rolling ball is used to assist the traction wheel in adjusting its position.

[0048] Specifically, when the traction wheel moves on the surface of the placing table 166, the rolling ball rotatably connected to the surface of the placing table 166 assists in adjusting the position of the traction wheel.

[0049] The technical solutions in the above embodiments of the present application at least have the following technical effects or advantages: The industrial camera 183 can detect the axis position of the traction wheel in real time, ensuring that the traction wheel always maintains the correct position before polishing, thus significantly improving the polishing accuracy and reducing the polishing unevenness or rejection rate caused by position deviation; precisely controlling the inflation of the airbag 162 to achieve fine adjustment and enhance adaptability. By adjusting the output of the air pump 164, fine control of the inflation of the airbag 162 can be achieved, thereby finely adjusting the position of the traction wheel; a plurality of rolling balls are rotatably connected to the upper surface of the placing table 166. The presence of the rolling balls significantly reduces the friction between the traction wheel and the placing table 166, enabling the traction wheel to move to the target position more easily and smoothly. This not only improves the operation convenience of the operator but also enhances the efficiency of position adjustment, thus improving the overall polishing operation efficiency.

[0050] Embodiment 4: When the above embodiment is used, the position of the traction wheel is fixed by the deformable sleeved block 161. However, during the use process, since the polishing block 135 needs to be in close contact with the traction wheel, when the polishing block 135 presses the traction wheel, due to the deformability of the sleeved block 161, the position of the traction wheel may move. Therefore, the above embodiment is improved as Figures 13 - 14 shown: The outer part of the sleeve block 161 is sleeved with a water injection film 163. The upper end of the water injection film 163 is fixed to the upper end of the sleeve block 161, and the lower end of the water injection film 163 is fixed to the lower end of the sleeve block 161; A water pump 165 is fixed inside the fixed block 141. The output end of the water pump 165 communicates with the gap between the water injection film 163 and the sleeve block 161, and the input end of the water pump 165 penetrates through the fixed block 141, the protective shell 110 and the water tank 150 to communicate with the water source; Specifically, when the water pump 165 works, it injects water into the gap between the water injection film 163 and the sleeve block 161 to enhance the hardness of the contact between the sleeve block 161 and the traction wheel; after a traction wheel is polished, the water pump 165 pumps out the water in the gap between the water injection film 163 and the sleeve block 161, and works in this way repeatedly.

[0051] The first telescopic rod 134, the second telescopic rod 142, the third telescopic rod 171 and the fourth telescopic rod 181 are all electric telescopic rods; The first electromagnet 112, the electric sliding table 133, the motor 138, the air pump 164, the water pump 165, the industrial camera 183, the first telescopic rod 134, the second telescopic rod 142, the third telescopic rod 171 and the fourth telescopic rod 181 are all prior arts and will not be elaborated here.

[0052] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: The introduction of the water injection film 163 can fill the gap between the contact surfaces of the sleeve block 161 and the traction wheel, and the hardness of the contact surface between the sleeve block 161 and the traction wheel is increased by injecting water through the water pump 165, effectively resisting the pressing force of the polishing block 135 on the traction wheel, fundamentally solving the problem of the displacement of the traction wheel caused by the deformation of the sleeve block 161. This ensures that the polishing block 135 and the traction wheel always maintain a tight and stable contact, thereby achieving more precise polishing, significantly improving the polishing accuracy and product quality, and reducing the uneven polishing or waste products caused by position deviation; the increase in the hardness of the sleeve block 161 makes the entire polishing system more stable, and the polishing block 135 can continuously and stably polish the traction wheel, reducing the polishing interruption or speed fluctuation caused by position adjustment, thereby improving the polishing efficiency. The stable polishing process also helps to extend the service life of the polishing block 135 and the equipment; the water pump 165 and the water injection film 163 achieve precise control of the water injection volume. The operator can adjust the water injection volume of the water pump 165 according to the actual polishing requirements, thereby precisely adjusting the hardness of the sleeve block 161. This adjustability enables the polishing device to adapt to the polishing requirements of traction wheels with different materials and sizes, further optimizing the polishing effect and improving the adaptability and flexibility of the equipment.
