Description

[0018] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-Figure 6As shown, a tool for disassembling and assembling coal mine equipment comprises a lower support column 1, a reduction motor 2, and a clutch mechanism. The lower support column 1 is vertically arranged and has a vertical reduction motor 2 installed inside. The clutch mechanism is installed on the upper part of the lower support column 1, and a radial upper support column 4 is installed on the upper part. The upper left part of the upper support column 4 is rotatably connected with a horizontal left support shaft 5 and a left hollow shaft 6. The left hollow shaft 6 is coaxially rotatably connected with the left support shaft 5. A left turbofan 7 is coaxially fixed to the left hollow shaft 6. A left support cylinder 8 is coaxially fixed to the left support shaft 5, and a plurality of upper ribs 801 are radially fixed. A No. 1 electromagnet 9 is fixed to the right part of the left support cylinder 8, and a main sliding column 10 is axially slidably connected to the left and right sides. A disc-shaped brush 11 is coaxially fixed to the left end of the main sliding column 10, and a No. 1 permanent magnet 12 is fixed to the right end. A conductive slip ring 13 is installed on the left end of the upper support column 4, and the stator of the conductive slip ring 13 is coaxially fixed with the upper support column 4. The rotor of the conductive slip ring 13 is connected to a plurality of columnar brushes 14 in a radially sliding manner at equal angles around the circumference. The rotor of the conductive slip ring 13 is fixed to each upper rib 801. Each columnar brush 14 is respectively fixed with a No. 3 permanent magnet 15. The rotor of the conductive slip ring 13 is fixed with a plurality of No. 3 electromagnets 16. The No. 3 electromagnets 16 can be magnetically attracted and repelled by the No. 3 permanent magnets 15. The right part of the upper support column 4 is rotatably connected to a right support shaft 17. The right support shaft 17 is A right sleeve 18 is coaxially fixed to the end, and a hexagonal sleeve 19 or a hexagonal plug rod 20 is inserted into the right sleeve 18. The rotor of the reduction motor 2 can be transmission-connected with the left support shaft 5, the left hollow shaft 6 and the right support shaft 17 through a clutch mechanism. The lower support column 1 is also fixed with a controller 21 and a speaker 22. The reduction motor 2, the first electromagnet 9, the third electromagnet 16, the controller 21 and the speaker 22 are electrically connected, and the controller 21 is electrically connected to the power supply.

[0020] When it is necessary to remove the bolt or nut, the rotor of the conductive slip ring 13 is intermittently inserted outside the head of the bolt or the outside of the nut, and then the No. 1 electromagnet 9 and the No. 3 permanent magnet 15 are controlled to pass positive current, so that the No. 3 permanent magnet 15 and the No. 3 electromagnet 16 repel each other, and the No. 1 electromagnet 9 and the No. 1 permanent magnet 12 repel each other, and then the bristles of the columnar brush 14 and the bristles of the disc brush 11 are close to the head of the bolt or the surface of the nut, and then the reduction motor 2 is controlled to rotate, so that the left support shaft 5 and the left hollow shaft 6 are rotated by the clutch mechanism, and then the rotor of the conductive slip ring 13 and the left support cylinder 8 are driven to rotate, so that each columnar brush 14 moves circumferentially, and the disc brush 11 rotates, and then the surface of the bolt or the surface of the screw 39 is cleaned. At the same time, the rotating left turbofan 7 can send air to the left, so that The dust and mineral powder that have fallen off are blown away to achieve a better cleaning effect. After cleaning, a reverse current is applied to the No. 1 electromagnet 9 and the No. 3 electromagnet 16, and the reduction motor 2 is controlled to stop, so that the No. 1 electromagnet 9 and the No. 1 permanent magnet 12 are magnetically attracted to each other, and the No. 2 electromagnet 28 and the No. 2 permanent magnet 25 are magnetically attracted to each other, and then the columnar brush 14 and the disc brush 11 are kept away from the bolt head or nut, and then the rotor of the conductive slip ring 13 is connected with the bolt or nut out of the gap, and then according to the size of the nut or bolt, the corresponding hexagonal sleeve 19 or hexagonal plug 20 is selected to be connected with the right sleeve 18, and then the hexagonal sleeve 19 or the hexagonal plug 20 is used to connect with the target bolt head or nut, and then the reduction motor 2 is controlled to rotate, and the bolt or nut can be tightened or loosened, thereby realizing the disassembly and assembly of the coal mine equipment.

[0021] The conductive slip ring 13 is radially slidingly connected to at least two mutually symmetrical auxiliary sliding columns 23, each of the auxiliary sliding columns 23 is rotatably connected to a roller 24, and is respectively fixed with a No. 2 permanent magnet 25, and a tension sensor 26 is respectively fixed in each of the auxiliary sliding columns 23, and each of the tension sensors 26 is respectively fixed with an inner tension spring 27 together with the rotor of the conductive slip ring 13, and the roller 24 is parallel to the upper support column 4, and the rotor of the conductive slip ring 13 is fixed with a plurality of No. 2 electromagnets 28, and the No. 2 electromagnets 28 can be magnetically attracted and repelled with the No. 2 permanent magnet 25, and the tension sensor 26, the No. 2 electromagnet 28 and the controller 21 are electrically connected.

[0022] Furthermore, when a positive current is applied to the third electromagnet 16, a positive current is also applied to the second electromagnet 28. At this time, the second electromagnet 28 and the second permanent magnet 25 repel each other, so that the auxiliary sliding column 23 approaches the surface of the bolt or the nut until the roller 24 fits the radial side of the bolt or the nut. As the rotor of the conductive slip ring 13 rotates, the roller 24 moves in an annular manner along the radial side of the bolt or the nut. Since the auxiliary sliding column 23 is symmetrically arranged, there is a minimum spacing between the rollers 24 during the rolling process, and the auxiliary sliding column 23 is symmetrically arranged. When the sliding column 23 approaches the bolt or nut, it will pull the inner tension spring 27, so that the data measured by the tension sensor 26 will change. Each data can reflect the degree of proximity of the auxiliary sliding column 23 to the bolt or nut. By matching the data with the database, the minimum spacing of the roller 24 during the rolling process can be known, so as to judge the size of the bolt or nut and announce it through the speaker 22. At this time, the staff can select the hexagonal sleeve 19 or hexagonal insert rod 20 of the corresponding size to loosen the target bolt or nut, which is convenient and quick.

[0023] The upper support column 4 is rotatably connected with a right hollow shaft 29, and the right hollow shaft 29 is coaxially rotatably connected with the right support shaft 17. A right turbofan 30 is coaxially fixed to the right hollow shaft 29. A plurality of right through holes 31 pass through the right sleeve 18 on the left and right sides. An annular support plate 32 is coaxially fixed to the inner wall of the right sleeve 18, and the hexagonal sleeve 19 can interfere with the support plate 32 to make it communicate with the right through hole 31.

[0024] Furthermore, when the bolt is loosened (limited to right-handed hexagonal bolts), due to the angle and deadweight of the bolt, when the bolt is detached from the coal mining equipment, it is also easy to detach from the hexagonal sleeve 19. By providing the right hollow shaft 29, the right turbofan 30, and the right through hole 31, when the hexagonal sleeve 19 is loosened to the target bolt, the reduction motor 2 is used to simultaneously drive the right hollow shaft 29 and the right support shaft 17 to rotate, and the right turbofan 30 can be used to draw air to the left, thereby generating suction on the target bolt to reduce its accidental falling.

[0025] The clutch mechanism includes a first bevel gear 33, a second bevel gear 34, a third bevel gear 35, a fourth bevel gear 36, a fifth bevel gear 37, a sixth bevel gear 38, a screw 39, a worm gear 40, a servo motor 41, and a worm 42. The upper support column 4 is slidably connected to the lower support column 1 left and right. The left support shaft 5 is coaxially fixed with the first bevel gear 33, and the left hollow shaft 6 is coaxially fixed with the second bevel gear 34. The rotating shaft of the reduction motor 2 is coaxially fixed with the third bevel gear 35 and the fourth bevel gear 36. The right support shaft 17 is coaxially fixed with the fifth bevel gear 37, and the right hollow shaft 29 is coaxially fixed with the sixth bevel gear 38. The upper support column 4 is rotatably connected with a screw 39, and the screw 39 is parallel to the upper support column 4. The screw 39 is coaxially fixed with a worm gear 40, and the screw 39 is threaded with the lower support column 1 The servo motor 41 is connected to the upper part of the lower support column 1, and a worm 42 is coaxially fixed to the rotating shaft of the servo motor 41, and is rotatably connected to the lower support column 1. The worm 42 is meshed with the worm wheel 40. When the servo motor 41 rotates forward and reversely, the cooperation between the worm wheel 40 and the worm 42 can make the screw 39 rotate forward and reverse, thereby driving the upper support column 4 to slide left and right compared with the lower support column 1. When the upper support column 4 moves to a certain position to the left compared with the lower support column 1, the first bevel gear 33 can be meshed with the third bevel gear 35 and the second bevel gear 34 can be meshed with the fourth bevel gear 36. When the upper support column 4 moves to a certain position to the right compared with the lower support column 1, the fifth bevel gear 37 can be meshed with the third bevel gear 35 and the sixth bevel gear 38 can be meshed with the fourth bevel gear 36.

[0026] By utilizing the self-locking property of the worm 42 and the worm wheel 40, it is possible to reduce accidental rotation of the worm wheel 40 and the screw 39, thereby reducing accidental left and right movement of the upper support column 4 relative to the lower support column 1, thereby ensuring that the meshing of the third bevel gear 35 and the fourth bevel gear 36 with the first bevel gear 33, the second bevel gear 34, the fifth bevel gear 37 and the sixth bevel gear 38 is stable and controllable.

[0027] The shaft of the reduction motor 2 is equipped with a torque sensor 43 , which is electrically connected to the controller 21 . The lower support column 1 is fixed with a control button 44 , a battery 45 and a charging socket 46 , which are electrically connected to the controller 21 .

[0028] Furthermore, when the reduction motor 2 is rotating, the torque generated by the shaft of the reduction motor 2 is monitored by the torque sensor 43. When the resistance is too large (such as the bolts or nuts have been tightened or are difficult to loosen), the reduction motor 2 is automatically controlled to stop working to avoid overload and damage to the reduction motor 2. The battery 45 can be powered by the charging socket 46, and the controller 21 can be controlled by pressing the control button 44.

[0029] The reduction motor 2 is fixed with a plurality of lower ribs 47, each of which is fixed to the inner wall of the lower support column 1. The reduction motor 2 is a dual-axis reduction motor 2, and a lower sleeve 48 is coaxially fixed to the bottom of the rotating shaft of the reduction motor 2. The lower sleeve 48 is plugged with a hexagonal column 49, and can also be plugged with the hexagonal sleeve 19 and the hexagonal column 49. A flat head plug 50 or a cross head plug is fixed to the bottom of the hexagonal column 49. The lower sleeve 48 is penetrated by a plurality of lower through holes 52 from top to bottom. The lower support column 1 The inner cavity is communicated with the inner cavity of the upper support column 4, and a support ring 53 is coaxially connected to the middle part of the lower support column 1, and an external tension spring 54 is fixed to the bottom end of the support ring 53. A lower support tube 55 is inserted in the outer gap of the lower support column 1, and the lower support tube 55 can rotate and slide up and down compared with the lower support column 1. The left and right parts of the lower support tube 55 are horizontally penetrated, and a soft shielding piece 56 is fixed at the penetration point of the lower support tube 55. When the shielding piece 56 is squeezed by external force, it can fit with the outer wall of the lower support column 1.

[0030] Furthermore, by providing the lower rib 47, air circulation around the reduction motor 2 is facilitated, especially when the left turbofan 7 or the right turbofan 30 is rotating, the heat dissipation effect of the reduction motor 2 is better. When cleaning the bolts or nuts, the lower support tube 55 can be held in the palm of the hand and the shielding sheet 56 can be squeezed to make the lower support tube 55 stationary relative to the lower support column 1 for easy holding. When the length of the target bolt is long (only referring to the hexagon socket bolt, the hexagon socket bolt, the slotted bolt and the cross-slot bolt), the lower sleeve 48 is pressed so that the bottom end of the lower sleeve 48 is against the surface of the coal mine equipment. The surface is then connected with the corresponding hexagonal sleeve 19 or hexagonal plug 20 or hexagonal column 49 and the lower sleeve 48, and then the hexagonal sleeve 19 or hexagonal plug 20 or slotted plug 50 or cross plug are connected with the target inner hexagonal bolt, outer hexagonal bolt, slotted bolt or cross slot bolt, and then the dual-axis reduction motor 2 is controlled to reverse, so that the target bolt can be loosened. During this period, the lower support tube 55 is continuously in contact with the surface of the coal mine equipment to indirectly support the bolt, thereby reducing the shaking during the loosening process, which may cause damage to the thread or difficulty in loosening.

[0031] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
