Description

Technical Field

[0001] The present invention relates to the technical field of electromechanical detection, in particular to a detection device for repairing electromechanical equipment in coal mines. Background Art

[0002] In coal mine production operations, electromechanical equipment is usually indispensable. As the power of production operations, the most common method is to use motors to drive various operating equipment. After long-term use, motors will inevitably have some faults. At this time, it is necessary to detect the faults of the motors and make targeted repairs.

[0003] According to a Chinese patent application with publication number 202221091484.1, a multifunctional electromechanical equipment detection device is disclosed. The rotating rod is driven to rotate by a turbine, thereby rotating the detection platform, and finally the electromechanical equipment to be detected on the top of the detection platform is rotated horizontally, which can adjust the angle of the electromechanical equipment and improve the maintenance efficiency. Since the motor needs to be powered on for testing during the maintenance and detection process, and certain faults may cause the motor to vibrate easily during operation, the above-mentioned electromechanical equipment detection device is only fixed by simply clamping the motor casing, which is difficult to resist motor vibration. The high-frequency vibration of the motor can easily loosen between the two clamps, posing a serious safety hazard. At the same time, due to loose positioning, the motor can easily fall off the detection platform and cause secondary damage. For this reason, we propose a detection device for coal mine electromechanical equipment maintenance to solve the above-mentioned technical problems. Summary of the Invention

[0022] As a preferred solution of the present invention, the translation stage further includes:

[0023] The guide rod is fixed on the side of the push plate close to the cylinder.

[0024] The guide frame is fixedly mounted on the bottom of the translation platform. The guide rod slides through the guide frame and is located between the front and rear guide rods.

[0025] As a preferred solution of the present invention, the translation stage further includes:

[0026] The bearing seats are fixedly installed on the top of the translation platform in a front and rear distribution. The two bearing seats are located on the periphery of the front and rear cams, and the rotating shaft is rotatably installed between the front and rear bearing seats through the bearing.

[0027] As a preferred solution of the present invention, the translation stage includes:

[0028] Locking bars are slidably arranged at the front and rear of the pillow plate;

[0029] The locking buckle is integrally formed and arranged at one end of the top of the lock bar near the positioning column;

[0030] The locking piece is integrally formed and arranged at the front and rear ends of the pressure plate close to the groove. The position and specifications of the locking piece are adapted to the locking buckle.

[0031] As a preferred solution of the present invention, the translation stage includes:

[0032] The slide grooves are distributed on the left and right sides and are opened on the front of the lock bar and pass through the inside of the lock bar;

[0033] The guide bolt is threadedly connected to the front and back of the pillow plate, the outer wall of the guide bolt is slidably connected to the inner wall of the slide groove, and the left end of the bottom of the guide bolt is fixedly connected to the top of the T-shaped sheet metal frame.

[0035] As a preferred solution of the present invention, two linear guide rails distributed front and back are fixedly installed on the top of the detection platform, and two linear sliders distributed left and right are slidably installed on the top of the linear guide rails. The tops of the two linear sliders are respectively fixedly connected to the bottoms of the left and right translation platforms by bolts.

[0036] As a preferred solution of the present invention, the front end of the top of the translation platform is penetrated by two inner thread holes distributed on the left and right, and the inner thread holes are threaded with locking bolts, and the bottoms of the locking bolts are in contact with the top of the detection platform.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. In the present invention, the mining motor is placed on the top of four pillow plates distributed left and right and front and back, and the mounting holes of the motor are aligned with the positioning posts on the top of the pillow plates, ensuring that the four positioning posts are inserted into the four mounting holes of the mining motor. The mining motor is initially positioned, and the limiting effect between the outer wall of the positioning post and the inner wall of the motor mounting hole ensures that the motor will not move sideways during the detection process, thereby avoiding secondary damage to the motor due to loose fixation and improving the safety of the detection.

[0039] 2. In the present invention, after the push plate moves and abuts against the side wall of the translation stage, when the raised portion of the cam rotates and contacts the top of the pressure plate, the pressure plate just slides into place along the outer wall of the sheet metal bracket. Under the action of the continued rotation of the cam, the raised portion of the cam presses the pressure plate downward, causing the pressure plate to drive the sheet metal bracket to rotate along the hinge with the hinge groove, so that the groove moves downward until the groove moves down to the periphery of the positioning column. Finally, the bottom of the pressure plate is located at the periphery of the groove opening and abuts against the top of the motor's machine foot mounting seat, exerting a downward squeezing force on the motor to prevent the motor from climbing up along the outer wall of the positioning column during the detection process, thereby further improving the positioning stability.

[0040] 3. In the present invention, since the pressure plate has not yet slid along the sheet metal bracket when the motor is placed, the motor housing will not interfere with the end of the pressure plate during the process of placing the motor on the periphery of the positioning column, thereby providing great convenience for placing the motor.

[0041] 4. In the present invention, when the bottom of the pressure plate contacts the top of the motor's foot mounting seat, the push plate just moves and contacts the side wall of the translation platform. Therefore, the push plate realizes the stopping effect through the translation platform, and the output rod of the cylinder continues to retract, continuing to drive the T-shaped sheet metal frame to move. During this period, the spring is compressed and accumulates force, and the T-shaped sheet metal frame continues to move to drive the locking bar to move. The locking bar can be more stable and smooth through the sliding connection of the slide groove and the guide bolt. At the same time, the movement of the lock bar drives the locking buckle to move to the top periphery of the locking plate, thereby locking the pressure plate to prevent the cylinder from being damaged prematurely due to long-term high-intensity load.

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] See also Figures 1 to 8 The technical solution provided by the present invention specifically includes the following embodiments:

[0053] A detection device for repairing electromechanical equipment in coal mines includes a detection platform 100 and an aluminum profile detection frame 300. The detection platform 100 is fixedly installed inside the aluminum profile detection frame 300. A detector 400 for repairing electromechanical equipment in coal mines is fixedly installed on the front of the aluminum profile detection frame 300. Two positioning parts symmetrically distributed on the left and right are provided on the top of the detection platform 100.

[0054] For further details, please refer to Figures 5 to 7 As shown:

[0055] The positioning part includes a translation platform 200, a pillow plate 201, a positioning column 202, a hinge groove 203, a sheet metal bracket 204 and a pressure plate 205. The translation platform 200 is symmetrically distributed on the top of the detection platform 100. The pillow plate 201 is fixedly installed at the front end and the rear end of the top of the translation platform 200. The positioning column 202 is fixedly set at the end of the top of the pillow plate 201 close to the center of the detection platform 100. The hinge groove 203 is opened at the end of the pillow plate 201 away from the positioning column 202. The sheet metal bracket 204 is hinged inside the hinge groove 203 and extends to the top of the pillow plate 201. A V-shaped spring piece 2024 is fixedly installed between the top of the pillow plate 201 and the bottom of the sheet metal bracket 204. The pressure plate 205 is slidably installed on the periphery of the sheet metal bracket 204. A groove 206 is opened at the end of the pressure plate 205 close to the positioning column 202.

[0056] Specifically, the mining motor is placed on top of four pillow plates 201 distributed left and right and front and back, and the mounting holes of the motor are aligned with the positioning posts 202 on the top of the pillow plates 201, ensuring that the four positioning posts 202 are inserted into the four mounting holes of the mining motor. The mining motor is initially positioned, and the limiting effect between the outer wall of the positioning post 202 and the inner wall of the motor mounting hole is used to ensure that the motor will not move sideways during the inspection process, thereby avoiding secondary damage to the motor due to loose fixation and improving the safety of the inspection.

[0057] For further details, please refer to Figure 6 、 Figure 7 As shown:

[0058] The translation stage 200 further includes a rotating shaft 207, a cam 208, a gear 209, a rack 2010, a bracket 2011, a push plate 2012, a guide rod 2013, a guide frame 2014, a cylinder 2015, a T-shaped sheet metal frame 2016, a spring 2017 and a bearing seat 2018. The rotating shaft 207 is mounted on the top of the pressure plate 205, the cam 208 is fixedly mounted on the front and rear of the outer wall of the rotating shaft 207, the cam 208 is located at the top of the pressure plate 205, and the outer wall of the cam 208 conflicts with the top of the pressure plate 205, the gear 209 is fixedly mounted on the middle of the outer wall of the rotating shaft 207, the rack 2010 is engaged with the bottom of the gear 209, the bracket 2011 is fixedly mounted on the bottom of the rack 2010, and the push plate 2012 is fixedly mounted on the bottom of the bracket 211 away from the rack 2010 At one end, the guide rod 2013 is fixedly installed on a side of the push plate 2012 close to the cylinder 2015 in a front-to-back distribution, the guide frame 2014 is fixedly installed at the bottom of the translation stage 200, the guide rod 2013 slides through the inside of the guide frame 2014, the guide rod 2013 is located between the front and rear guide rods 2013, the cylinder 2015 is fixedly installed at the bottom of the translation stage 200, the T-shaped sheet metal frame 2016 is fixedly installed at the end of the output rod of the cylinder 2015, the spring 2017 is fixedly installed between the push plate 2012 and the T-shaped sheet metal frame 2016, the bearing seats 2018 are fixedly installed on the top of the translation stage 200 in a front-to-back distribution, the two bearing seats 2018 are located on the periphery of the front and rear cams 208, and the rotating shaft 207 is rotatably installed between the front and rear bearing seats 2018 through the bearing.

[0059] Specifically, after the initial positioning of the motor is completed, the cylinder 2015 is started, and the output rod of the cylinder 2015 is retracted to drive the T-shaped sheet metal frame 2016 to move toward the cylinder body of the cylinder 2015. The movement of the T-shaped sheet metal frame 2016 drives the push plate 2012 to move together under the elastic support of the spring 2017. Since the push plate 2012 is slidably connected to the guide frame 2014 through the front and rear guide rods 2013, the movement of the push plate 2012 can be more stable and smooth. At the same time, the movement of the push plate 2012 also drives the bracket 211 The rack 2010 moves together, causing the gear 209 meshing with the rack 2010 to rotate, and driving the rotating shaft 207 and the front and rear cams 208 to rotate synchronously between the front and rear bearing seats 2018. Since the outer wall of the cam 208 directly contacts the top of the pressure plate 205, the rotating cam 208 drives the pressure plate 205 to slide along the outer wall of the sheet metal bracket 204 toward the positioning column 202 under the action of friction. During this period, due to the elastic support of the V-shaped spring piece 2024, the sheet metal bracket 204 will not move along the direction of the positioning column 202. The hinge groove 203 is hinged and rotates. When the push plate 2012 moves and contacts the side wall of the translation stage 200, when the raised portion of the cam 208 rotates and contacts the top of the pressure plate 205, the pressure plate 205 just slides into place along the outer wall of the sheet metal bracket 204. Under the action of the continued rotation of the cam 208, the raised portion of the cam 208 presses the pressure plate 205 downward, causing the pressure plate 205 to drive the sheet metal bracket 204 to rotate along the hinge groove 203, causing the groove 206 to move downward until the groove 206 moves down to the periphery of the positioning column 202. The bottom of the pressure plate 205 is located at the outer periphery of the opening of the groove 206 and contacts the top of the motor's foot mounting seat, applying a downward squeezing force to the motor to prevent the motor from climbing up along the outer wall of the positioning column 202 during the detection process, thereby further improving the positioning stability. It should be noted that when the motor is placed, the pressure plate 205 has not yet slid along the sheet metal bracket 204. Therefore, when the motor is placed on the outer periphery of the positioning column 202, the motor casing will not interfere with the end of the pressure plate 205, thereby providing great convenience for the placement of the motor.

[0060] For further details, please refer to Figure 7 、 Figure 8 As shown:

[0061] The translation platform 200 includes a locking bar 2019, a locking buckle 2020, a locking plate 2021, a slide groove 2022 and a guide bolt 2023. The locking bar 2019 is slidably arranged at the front and rear of the pillow plate 201. The locking buckle 2020 is integrally formed and arranged at one end of the top of the locking bar 2019 near the positioning column 202. The locking plate 2021 is integrally formed and arranged at one end of the front and rear of the pressure plate 205 near the groove 206. The position and specifications of the locking plate 2021 are compatible with the locking buckle 2020. The slide groove 2022 is distributed on the left and right sides and is opened on the front of the locking bar 2019 and passes through the inside of the locking bar 2019. The guide bolt 2023 is threadedly connected to the front and back of the pillow plate 201. The outer wall of the guide bolt 2023 is slidably connected to the inner wall of the slide groove 2022. The bottom left end of the guide bolt 2023 is fixedly connected to the top of the T-shaped sheet metal frame 2016.

[0062] Specifically, when the bottom of the pressure plate 205 contacts the top of the motor's foot mounting seat, the push plate 2012 just moves and contacts the side wall of the translation platform 200. Therefore, the push plate 2012 realizes the stopping effect through the translation platform 200, and the output rod of the cylinder 2015 continues to retract, continuing to drive the T-shaped sheet metal frame 2016 to move. During this period, the spring 2017 is compressed and accumulates force, and the T-shaped sheet metal frame 2016 continues to move to drive the locking bar 2019 to move. The locking bar 2019 can be more stable and smooth through the sliding connection between the slide groove 2022 and the guide bolt 2023. At the same time, the movement of the lock bar 2019 drives the locking buckle 2020 to move to the top periphery of the locking plate 2021, thereby locking the pressure plate 205.

[0063] For further details, please refer to Figure 4 As shown:

[0064] Two linear guide rails 2025 distributed front and back are fixedly installed on the top of the detection platform 100. Two linear sliders 2026 distributed left and right are slidably installed on the top of the linear guide rails 2025. The tops of the two linear sliders 2026 are fixedly connected to the bottoms of the left and right translation platforms 200 respectively by bolts.

[0065] Specifically, the distance between the left and right translation platforms 200 is adjusted along the sliding connection direction of the linear guide rail 2025 and the linear slider 2026 , thereby adapting to the maintenance and inspection of mining motors of different widths.

[0066] For further details, please refer to Figure 3 、 Figure 5 As shown:

[0067] The front end of the top of the translation platform 200 is penetrated by two inner thread holes 2027 distributed on the left and right. The inner thread holes 2027 are screwed with locking bolts 2028, and the bottoms of the locking bolts 2028 are in contact with the top of the detection platform 100.

[0068] Specifically, the top of the detection platform 100 is pressed by the bottom of the locking bolt 2028 to position the entire translation platform 200 to prevent the translation platform 200 from moving along the sliding connection direction of the linear slider 2026 and the linear guide rail 2025. After loosening the locking bolt 2028, the distance between the left and right translation platforms 200 can be adjusted. When the distance adjustment of the two translation platforms 200 is completed, the locking bolt 2028 is tightened again to prevent the adjusted translation platform 200 from moving again.

[0069] When the detection device for coal mine electromechanical equipment maintenance of this solution is in operation, the distance between the left and right translation platforms 200 is first adjusted according to the specifications of the mining motor. Specifically, the locking bolt 2028 is loosened, and the distance between the left and right translation platforms 200 is adjusted along the sliding connection direction of the linear guide rail 2025 and the linear slider 2026. After the distance adjustment of the two translation platforms 200 is completed, the locking bolt 2028 is tightened again to prevent the adjusted translation platform 200 from moving again.

[0070] Place the mining motor on top of the four pillow plates 201 distributed left and right and front and back, and align the motor's mounting holes with the positioning posts 202 on the top of the pillow plates 201, ensuring that the four positioning posts 202 are inserted into the four mounting holes of the mining motor. Preliminary positioning of the mining motor is performed, and the limiting effect between the outer wall of the positioning posts 202 and the inner wall of the motor mounting holes is used to ensure that the motor will not move sideways during the inspection process, thereby avoiding secondary damage to the motor caused by loose hard fixation and improving the safety of the inspection. After completing the preliminary positioning of the motor, start the cylinder 2015, and the output rod of the cylinder 2015 is used. The retraction drives the T-shaped sheet metal frame 2016 to move toward the cylinder body of the cylinder 2015. The movement of the T-shaped sheet metal frame 2016 drives the push plate 2012 to move together under the elastic support of the spring 2017. Since the push plate 2012 is slidably connected to the guide frame 2014 through the front and rear guide rods 2013, the movement of the push plate 2012 can be more stable and smooth. At the same time, the movement of the push plate 2012 also drives the bracket 2011 and the rack 2010 to move together, causing the gear 209 meshing with the rack 2010 to rotate, and driving the rotating shaft 207 and the front and rear cams 208 to rotate in the front. The two rear bearing seats 2018 rotate synchronously. Since the outer wall of the cam 208 directly contacts the top of the pressure plate 205, the rotating cam 208 drives the pressure plate 205 to slide along the outer wall of the sheet metal bracket 204 toward the direction of the positioning column 202 under the action of friction. During this period, due to the elastic support of the V-shaped spring piece 2024, the sheet metal bracket 204 will not rotate along the hinge with the hinge groove 203. When the push plate 2012 moves and contacts the side wall of the translation stage 200, when the raised part of the cam 208 rotates and contacts the top of the pressure plate 205, the pressure plate 205 just moves along the outer wall of the sheet metal bracket 204. The outer wall of the sheet metal bracket 204 slides into place. Under the action of the continued rotation of the cam 208, the raised portion of the cam 208 presses the pressure plate 205 downward, causing the pressure plate 205 to drive the sheet metal bracket 204 to rotate along the hinge with the hinge groove 203, so that the groove 206 moves downward until the groove 206 moves down to the periphery of the positioning column 202. Finally, the bottom of the pressure plate 205 is located at the periphery of the opening of the groove 206 and contacts the top of the motor foot mounting seat, exerting a downward squeezing force on the motor to prevent the motor from climbing up along the outer wall of the positioning column 202 during the detection process, further improving the positioning stability.

[0071] When the bottom of the pressure plate 205 hits the top of the motor's foot mounting seat, the push plate 2012 just moves and hits the side wall of the translation platform 200. Therefore, the push plate 2012 realizes the stopping effect through the translation platform 200, and the output rod of the cylinder 2015 continues to retract, continuing to drive the T-shaped sheet metal frame 2016 to move. During this period, the spring 2017 is compressed and accumulates force, and the T-shaped sheet metal frame 2016 continues to move, driving the locking bar 2019 to move. The locking bar 2019 can be more stable and smooth through the sliding connection between the slide groove 2022 and the guide bolt 2023. At the same time, the movement of the lock bar 2019 drives the locking buckle 2020 to move to the top periphery of the locking plate 2021, thereby locking the pressure plate 205.

[0072] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principles and spirit of the invention.
