Moreover, when the coal mine electromechanical equipment shakes, it is easy to cause uneven force or tilt of the coal mine electromechanical equipment, thereby greatly increasing the pressure on the wire rope and the lifting equipment, and greatly increasing the probability of damage to the wire rope and the lifting equipment or the probability of performance degradation.

[0015] As a preferred embodiment of the present invention, a lifting method for transporting electromechanical equipment in a coal mine comprises the following steps:

[0016] Step 1: Move the connecting plate to a suitable position, use a hook to hang the coal mine electromechanical equipment, and then rotate the double threaded rod, so that the rotation of the double threaded rod drives a pair of clamping plates to move toward the center, so that the pair of clamping plates clamp and fix the coal mine electromechanical equipment;

[0017] Step 2: When the coal mine electromechanical equipment is hoisted for transportation, the connecting plate is fixed by a fixing rod and a fixing shell;

[0018] Step 3: When the connecting plate drives the clamping plate to descend and the slide plate contacts the ground, the connecting plate continues to descend and the slide plate shrinks into the slide slot. When the slide plate shrinks, the guide plate will press against the right-angled triangle block, so that the right-angled triangle block drives the support plate to shrink. When the clamping plate is clamped and fixed, the connecting plate drives the coal mine electromechanical equipment to rise. At this time, the slide plate stretches under the elastic force of the first spring, so that the slide plate drives the support plate to move downward. When the support plate moves downward, under the action of the guide plate and the second spring, the support plate stretches to the bottom of the coal mine electromechanical equipment.

[0019] Step 4: When the motor drives the rotating shaft to rotate, the rotating shaft drives the winch to rotate, so that the wire rope extends, and the connecting plate drops at this time. Because the rotating shaft rotates, it drives the gear 1 to rotate, so that the gear 1 drives the gear 2 to rotate. Because the gear 2 and the gear groove are meshed with each other, when the gear 2 rotates, it drives the lifting column to move on one side of the outer wall of the sliding column, so that the lifting column drops;

[0020] Step 5: When the motor drives the rotating shaft to rotate, the rotation of the rotating shaft drives the bevel gear 3 to rotate, and the bevel gear drives the bevel gear 4 and the threaded rod 1 to rotate, so that the rotation of the threaded rod 1 drives the adjustment plate and the moving column to rotate, so that the lifting column retracts or extends;

[0021] Step 6: When the lifting column descends or ascends, the lifting column drives the gear bar to move through the first connecting plate, so that the movement of the gear bar drives the gear five to rotate, and the gear five drives the rotating rod one to rotate. Because the outer wall ends of the linkage rod and the rotating rod one are fixedly connected with sprockets, and a pair of sprockets are connected by a chain, the rotating rod one drives the linkage rod to rotate through the sprocket and the chain, so that the linkage rod drives the bevel gear seven to rotate, and the bevel gear seven drives the bevel gear six and the cylinder to rotate, so that the cylinder drives the sliding column and the lifting column to change the angle;

[0022] Step 7: When the coal mine electromechanical equipment is being transported and the angle does not need to be changed, the threaded rod 2 is rotated to drive the adjusting block and the adjusting shell to move, so that the adjusting shell drives the bevel gear 7 to move, so that the bevel gear 7 is out of meshing state with the bevel gear 6;

[0023] Step 8: Turn the bolt to move it out of the thread groove, and the positioning block and the adjusting housing are now released;

[0024] Step nine: By rotating threaded rod three, since threaded rod three is threadedly connected to bevel gear six, the movement of threaded rod three drives bevel gear six to move up and down.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. When the coal mine electromechanical equipment is hoisted for transportation, a pair of clamping plates clamp and fix the coal mine electromechanical equipment to make it more stable. When the connecting plate rises, the fixing rod on the connecting plate slides on the inner wall of the fixing shell, and the connecting plate is fixed by the fixing rod and the fixing shell, so that it can only move up and down but cannot rotate or shake. The fixing rod and the fixing shell fix the connecting plate, and the connecting plate and the clamping plate fix the coal mine electromechanical equipment, thereby cooperating with each other to make the coal mine electromechanical equipment more stable during transportation, thereby further improving the safety of coal mine electromechanical equipment transportation.

[0027] 2. When the motor drives the rotating shaft to rotate, the rotating shaft drives the winch to rotate, so that the wire rope extends, and the connecting plate drops at this time. Because the rotating shaft rotates, it also drives gear one to rotate, so that gear one drives gear two to rotate. Because gear two and the gear groove are meshed with each other, when gear two rotates, it drives the lifting column to move on one side of the outer wall of the sliding column, so that the lifting column drops. Conversely, when the lifting column rises, the wire rope contracts and the connecting plate rises, so that the device lowers the position of the lifting column while the connecting plate drops, making the connecting plate more efficient in lowering to the appropriate position, and the efficiency of the connecting plate in driving the coal mine electromechanical equipment to a certain height is also higher. In addition, it is completed by a single motor, so that the working efficiency of the device is improved while reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figure 1-Figure 8As shown, the lifting equipment for transporting electromechanical equipment in coal mines comprises a fixed seat 1; a sliding column 3 is provided at the top of the outer wall of the fixed seat 1 through a cylinder 2; a lifting column 4 is provided on one side of the outer wall of the sliding column 3; a pulley 5 is provided on the inner side wall of the lifting column 4; a motor 6 is fixedly connected to one side of the outer wall of the lifting column 4 through a fixed block; a rotating shaft 7 is provided at the output end of the motor 6; a capstan 8 is fixedly connected to the outer side wall of the rotating shaft 7; a steel wire rope 9 is provided on the inner side wall of the capstan 8, and the steel wire rope 9 matches the pulley 5; a connecting plate 10 is provided at the bottom end of the outer wall of the steel wire rope 9; a hook 11 is provided at the bottom end of the outer wall of the connecting plate 10; an auxiliary mechanism is provided at the top of the outer wall of the connecting plate 10; a square through groove 12 is opened at the top of the outer wall of the connecting plate 10; a pair of clamping plates 13 are slidably connected to the inner side wall of the square through groove 12; a double-threaded rod 14 is rotatably connected to the top of the outer wall of the connecting plate 10 through a first square plate; one end of the outer wall of the double-threaded rod 14 is penetrated A pair of clamping plates 13 are passed through, and the double-threaded rod 14 is threadedly connected to the pair of clamping plates 13. By moving the connecting plate 10 to a suitable position, the coal mine electromechanical equipment is hoisted with the hook 11, and then the double-threaded rod 14 is rotated, so that the rotation of the double-threaded rod 14 drives the pair of clamping plates 13 to move toward the center, so that the pair of clamping plates 13 clamps and fixes the coal mine electromechanical equipment. At this time, the coal mine electromechanical equipment is lifted and transported by the lifting column 4 and the wire rope 9. Because the coal mine electromechanical equipment is clamped and fixed, the lifted coal mine electromechanical equipment will not slip or shake during transportation, thereby greatly reducing the probability of accidents. The clamping and fixing can also prevent the coal mine electromechanical equipment from being damaged due to uneven force during the lifting process, further improving the safety of the operation, and the clamping plate 13 plays a protective role on the surface and functional parts of the coal mine electromechanical equipment, reducing the damage to the coal mine electromechanical equipment during the lifting process.

[0041] A group of gear grooves 24 are provided on one side of the outer wall of the sliding column 3; one side of the outer wall of the lifting column 4 is slidably connected to one side of the outer wall of the sliding column 3; a gear 1 25 is fixedly connected to the outer wall of the rotating shaft 7; a square block 26 is fixedly connected to one side of the outer wall of the lifting column 4; one side of the outer wall of the square block 26 is rotatably connected to a gear 2 27 through a first round rod, and the gear 2 27 and the gear 1 25 are meshed with each other; the gear 2 27 and the gear groove 24 are meshed with each other. When the motor 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the winch 8 to rotate, so that the wire rope 9 is extended, and at this time the connecting plate 10 descends, because the rotating shaft 7 rotates and drives the gear 1 25 to rotate at the same time, The gear 1 25 drives the gear 2 27 to rotate. Since the gear 27 and the gear groove 24 are meshed with each other, when the gear 27 rotates, it drives the lifting column 4 to move on the outer wall side of the sliding column 3, so that the lifting column 4 is lowered. On the contrary, when the lifting column 4 rises, the wire rope 9 contracts and the connecting plate 10 rises. The device lowers the position of the lifting column 4 while the connecting plate 10 descends, making the connecting plate 10 more efficient in lowering to the appropriate position. The connecting plate 10 also drives the coal mine electromechanical equipment to a certain height more efficiently. This is accomplished by a single motor 6, so that the working efficiency of the device is improved while reducing energy consumption.

[0042] One side of the outer wall of the sliding column 3 is rotatably connected to a rotating rod 1 32; a gear 5 33 is fixedly connected to the outer wall of the rotating rod 1 32; one side of the outer wall of the lifting column 4 is fixedly connected to a gear bar 34 through a first connecting rod, and the gear bar 34 and the gear 5 33 are meshed with each other; the bottom end of the outer wall of the cylinder 2 is rotatably connected to the top end of the outer wall of the fixing seat 1; the top end of the outer wall of the cylinder 2 is fixedly connected to the bottom end of the outer wall of the sliding column 3; the top end of the outer wall of the fixing seat 1 is rotatably connected to a linkage rod 35 through a sixth square plate; one end of the outer wall of the linkage rod 35 and the rotating rod 1 32 are fixedly connected to a sprocket 36, and a pair of sprockets 36 are connected by a chain 37; a bevel gear 6 38 is provided on the outer wall of the cylinder 2; a bevel gear 7 39 is provided on the other end of the outer wall of the linkage rod 35, and the bevel gear 6 38 matches the bevel gear 7 39. When the lifting column 4 descends or rises, the lifting column The gear bar 34 is driven to move through the first connecting plate 10. Since the gear bar 34 and the gear five 33 are meshed with each other, the movement of the gear bar 34 drives the gear five 33 to rotate, and the gear five 33 drives the rotating rod one 32 to rotate. Since the linkage rod 35 and one end of the outer wall of the rotating rod one 32 are fixedly connected with a sprocket wheel 36, and a pair of sprocket wheels 36 are connected by a chain 37, the rotating rod one 32 drives the linkage rod 35 to rotate through the sprocket wheel 36 and the chain 37, so that the linkage rod 35 drives the bevel gear seven 39 to rotate, and the bevel gear seven 39 drives the bevel gear six 38 and the cylinder 2 to rotate, so that the cylinder 2 drives the sliding column 3 and the lifting column 4 to change the angle, so that the device can not only transport the coal mine electromechanical equipment to a suitable height, distance and position, but also change the angle at the same time, so that the transportation range of the device is wider and the device is more practical.

[0043] The auxiliary mechanism includes a fixing rod 15; the bottom ends of the outer walls of a pair of fixing rods 15 are fixedly connected to the top ends of the outer walls of the connecting plate 10; the opposite sides of the outer walls of the lifting column 4 are fixedly connected with fixing shells 16; the outer walls of a pair of fixing rods 15 are respectively slidably connected to the inner walls of a pair of fixing shells 16. When the coal mine electromechanical equipment is lifted for transportation, a pair of clamping plates 13 clamp and fix the coal mine electromechanical equipment to make it more stable. When the connecting plate 10 rises, the fixing rod 15 on the connecting plate 10 slides on the inner wall of the fixing shell 16, and the connecting plate 10 is fixed by the fixing rod 15 and the fixing shell 16, so that it can only move up and down but not rotate or shake, so that the fixing rod 15 and the fixing shell 16 fix the connecting plate 10, and the connecting plate 10 and the clamping plate 13 fix the coal mine electromechanical equipment, thereby cooperating with each other to make the coal mine electromechanical equipment more stable during transportation, thereby further improving the safety of the transportation of coal mine electromechanical equipment.

[0044] The lifting column 4 includes a moving shell 401 and a moving column 402; the outer wall of the moving column 402 is slidably connected to the inner wall of the moving shell 401; the top of the outer wall of the moving column 402 is fixedly connected to an adjusting plate 28; the top of the outer wall of the moving shell 401 is rotatably connected to a threaded rod 29 through a fifth square plate, and one end of the outer wall of the threaded rod 29 passes through the adjusting plate 28; the threaded rod 29 is threadedly connected to the adjusting plate 28; one end of the outer wall of the rotating shaft 7 is fixedly connected to a bevel gear 3 30; one end of the outer wall of the threaded rod is fixedly connected to a bevel gear 4 31, and the bevel gear 4 31 and the bevel gear 3 30 are meshed with each other. When the motor 6 drives the rotating shaft 7 to rotate, the rotation of the rotating shaft 7 drives the bevel gear 3 30 to rotate, and the bevel gear drives the bevel gear 4 31 and the threaded rod 29 to rotate, so that the rotation of the threaded rod 29 drives the adjusting plate 2 8. The movable column 402 rotates to make the lifting column 4 contract or extend, thereby coordinating the up and down movement of the lifting column 4 and the extension and retraction of the wire rope 9, so that when the lifting column 4 descends and the wire rope 9 extends to make the connecting plate 10 descend, the lifting column 4 contracts, so that the connecting plate 10 and the clamping plate 13 are moved to a suitable nearby position, thereby facilitating the clamping and transportation of the coal mine electromechanical equipment. When the coal mine electromechanical equipment is transported, the connecting plate 10 and the lifting column 4 rise while the lifting column 4 extends, so that the coal mine electromechanical equipment is transported to a distant position. Because the extension and retraction of the wire rope 9, the rise or fall of the lifting column 4, and the extension or contraction of the lifting column 4 are all completed synchronously and are completed by a motor 6, the working efficiency of the device is further improved, and the energy consumption is greatly reduced, which is not only lower in cost but also higher in efficiency.

[0045] The linkage rod 35 includes a circular rod 351 and an adjusting shell 352; the outer side wall of the circular rod 351 is slidably connected to the inner side wall of the adjusting shell 352; the outer side wall of the circular rod 351 is rotatably connected to the threaded rod 2 40 through the eighth square plate; an adjusting block 41 is fixedly connected to one side of the outer wall of the adjusting shell 352; one end of the outer wall of the threaded rod 2 40 passes through the adjusting block 41, and the threaded rod 2 40 is threadedly connected to the adjusting block 41. When the coal mine electromechanical equipment is transported and there is no need to change the angle, the threaded rod 2 40 is rotated to drive the adjusting block 41 and the adjusting shell 352 to move, so that the adjusting shell 352 drives the bevel gear 7 39 to move, so that the bevel gear 7 39 is disengaged from the bevel gear 6 38. At this time, the cylinder 2 is fixed. At this time, when the device is used to transport the coal mine electromechanical equipment, it will not rotate to change the angle. When the angle needs to be changed, the threaded rod 2 40 is reversed to make the bevel gear 7 39 mesh with the bevel gear 6 38, making the device more flexible and convenient, and thus more practical.

[0046] A slide groove 17 is provided at the bottom end of the outer wall of the clamping plate 13; a slide plate 18 is fixedly connected to the top end of the inner wall of the slide groove 17 through a first spring, and the outer wall of the slide plate 18 is slidably connected to the inner wall of the slide groove 17; a first through groove 19 is provided on one side of the outer wall of the slide plate 18; a support plate 20 is slidably connected to the inner side wall of the first through groove 19; a pair of second springs 21 are fixedly connected to the top end of the outer wall of the support plate 20 through a pair of second blocks, and one end of the outer wall of the pair of second springs 21 is fixedly connected to one side of the outer wall of the slide plate 18; a right-angled triangle block 22 is fixedly connected to the top end of the outer wall of the support plate 20; a guide plate 23 is fixedly connected to one side of the outer wall of the clamping plate 13, and the bottom end of the outer wall of the guide plate 23 is slidably connected to the inclined surface of one side of the outer wall of the right-angled triangle block 22.

When the clamping plate 13 is clamped and fixed, the connecting plate 10 drives the coal mine electromechanical equipment to rise. At this time, the slide plate 18 stretches under the elastic force of the first spring, so that the slide plate 18 drives the support plate 20 to move downward. When the support plate 20 moves downward, under the action of the guide plate 23 and the second spring 21, the support plate 20 will also stretch. At this time, a part of the support plate 20 moves to the bottom of the coal mine electromechanical equipment. At this time, the coal mine electromechanical equipment is supported by the support plate 20 at the bottom, clamped and fixed by the clamping plates 13 on both sides, and supported by the hook 11 and the wire rope 9, so that the coal mine electromechanical equipment has multiple support points and force points, thereby reducing the pressure of the hook 11 and the wire rope 9, making the coal mine electromechanical equipment more convenient and safe when transporting, and reducing the wear of the hook 11 and the wire rope 9, and prolonging the service life of the hook 11 and the wire rope 9.

By rotating the bolt 42, the bolt 42 is moved out of the threaded groove 44. At this time, the blocking block 43 is released from the adjusting shell 352, making it easy to replace the bevel gear seven 39 of the device, so that the device can replace the appropriate bevel gear seven 39 according to needs. When the device transports coal mine electromechanical equipment, the angle change of the device during transportation can be adjusted by replacing the bevel gear seven 39, so that it is more practical and convenient, and it is more convenient to transport coal mine electromechanical equipment at different angles.

[0048] Embodiment 2:

[0049] See also Figure 6-Figure 7 As shown, the inner wall of bevel gear six 38 is slidably connected to the outer wall of cylinder 2; the outer wall of cylinder 2 is rotatably connected with threaded rod three 45 through the ninth square plate, and the bottom end of the outer wall of threaded rod three 45 passes through bevel gear six 38; threaded rod three 45 is threadedly connected to bevel gear six 38, and by rotating threaded rod three 45, since threaded rod three 45 is threadedly connected to bevel gear six 38, the movement of threaded rod three 45 drives bevel gear six 38 to move up and down, so that bevel gear seven 39 is replaced and adjusted. If the replaced bevel gear seven 39 changes too much, it is easy to cause it to be unable to mesh with bevel gear six 38. The rotation of threaded rod three 45 drives bevel gear six 38 to move up and down, so that bevel gear six 38 and replaced bevel gear seven 39 are replaced and fit, so that the replacement range of bevel gear seven 39 is increased, thereby making the upper and lower limits of the angle change range of the device increased, making it more practical.

[0050] When the present invention is in use, the connecting plate 10 is moved to a suitable position, and the hook 11 is used to hang the coal mine electromechanical equipment, and then the double-threaded rod 14 is rotated, so that the rotation of the double-threaded rod 14 drives a pair of clamping plates 13 to move toward the center, so that the pair of clamping plates 13 clamps and fixes the coal mine electromechanical equipment. Because the coal mine electromechanical equipment is clamped and fixed, the lifted coal mine electromechanical equipment will not slip or shake during transportation, thereby greatly reducing the probability of accidents. The clamping and fixing can also prevent the coal mine electromechanical equipment from being damaged due to uneven force during the lifting process, further improving the safety of the operation, and the clamping plate 13 protects the surface and functional parts of the coal mine electromechanical equipment, reducing the damage to the coal mine electromechanical equipment during the lifting process.

[0051] When the coal mine electromechanical equipment is lifted for transportation, a pair of clamping plates 13 clamps and fixes the coal mine electromechanical equipment. When the connecting plate 10 rises, the fixing rod 15 on the connecting plate 10 slides on the inner wall of the fixing shell 16, and the connecting plate 10 is fixed by the fixing rod 15 and the fixing shell 16, so that it can only move up and down but cannot rotate or shake, so that the fixing rod 15 and the fixing shell 16 fix the position of the connecting plate 10, and the connecting plate 10 and the clamping plate 13 fix the coal mine electromechanical equipment, thereby cooperating with each other to make the coal mine electromechanical equipment more stable during transportation, thereby further improving the safety of the transportation of coal mine electromechanical equipment.

[0052] When the connecting plate 10 drives the clamping plate 13 to descend and prepare to clamp and fix the coal mine electromechanical equipment, when the clamping plate 13 descends to a certain position, the slide plate 18 will touch the ground, and the connecting plate 10 continues to descend, and the slide plate 18 shrinks into the slide groove 17. When the slide plate 18 shrinks, the guide plate 23 will resist the right-angled triangle block 22, so that the right-angled triangle block 22 drives the support plate 20 to shrink. When the clamping plate 13 is clamped and fixed, the connecting plate 10 drives the coal mine electromechanical equipment to rise. At this time, the slide plate 18 is in the first spring state. The slide plate 18 stretches under the elastic force of the spring, so that the support plate 20 drives the support plate 20 to move downward. When the support plate 20 moves downward, under the action of the guide plate 23 and the second spring 21, the support plate 20 will also stretch. At this time, a part of the support plate 20 moves to the bottom of the coal mine electromechanical equipment. At this time, the coal mine electromechanical equipment is supported by the support plate 20 at the bottom, clamped and fixed by the clamping plates 13 on both sides, and supported by the hook 11 and the wire rope 9, so that the coal mine electromechanical equipment has multiple support points and force points, reducing the pressure of the hook 11 and the wire rope 9.

[0053] When the motor 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the winch 8 to rotate, and the wire rope 9 is extended. At this time, the connecting plate 10 descends. Because the rotating shaft 7 rotates, it drives the gear 1 25 to rotate, so that the gear 1 25 drives the gear 2 27 to rotate. Because the gear 2 27 and the gear groove 24 are meshed with each other, when the gear 27 rotates, it drives the lifting column 4 to move on the outer wall side of the sliding column 3, so that the lifting column 4 descends. Conversely, when the lifting column 4 rises, the wire rope 9 contracts and the connecting plate 10 rises, so that the device lowers the position of the lifting column 4 while the connecting plate 10 descends, making the connecting plate 10 more efficient in descending to the appropriate position, and the efficiency of the connecting plate 10 driving the coal mine electromechanical equipment to a certain height is also higher. In addition, it is completed by a single motor 6, so that the working efficiency of the device is improved while reducing energy consumption.

[0054] When the motor 6 drives the rotating shaft 7 to rotate, the rotation of the rotating shaft 7 drives the bevel gear three 30 to rotate, and the bevel gear drives the bevel gear four 31 and the threaded rod 1 29 to rotate, so that the rotation of the threaded rod 1 29 drives the adjusting plate 28 and the moving column 402 to rotate, so that the lifting column 4 contracts or extends, thereby cooperating with the up and down movement of the lifting column 4 and the extension and retraction of the wire rope 9, so that when the lifting column 4 descends and the wire rope 9 extends to make the connecting plate 10 descend, the lifting column 4 contracts, so that the connecting plate 10 and the clamping plate 13 are moved to a suitable nearby position, thereby facilitating the clamping and transportation of the coal mine electromechanical equipment. When the coal mine electromechanical equipment is transported, the connecting plate 10 and the lifting column 4 rise while the lifting column 4 extends, so that the coal mine electromechanical equipment is transported to a distant position. Because the extension and retraction of the wire rope 9, the rise or fall of the lifting column 4, and the extension or contraction of the lifting column 4 are all completed synchronously and are completed by a motor 6, the working efficiency of the device is further improved, and the energy consumption is greatly reduced, which is not only lower in cost but also higher in efficiency.

[0055] When the lifting column 4 descends or rises, the lifting column 4 drives the gear bar 34 to move through the first connecting plate 10. Because the gear bar 34 and the gear five 33 are meshed with each other, the movement of the gear bar 34 drives the gear five 33 to rotate, and the gear five 33 drives the rotating rod 1 32 to rotate. Because the linkage rod 35 and one end of the outer wall of the rotating rod 1 32 are fixedly connected with a sprocket 36, and a pair of sprockets 36 are connected by a chain 37, the rotating rod 1 32 drives the linkage rod 35 to rotate through the sprocket 36 and the chain 37, so that the linkage rod 35 drives the bevel gear seven 39 to rotate, and the bevel gear seven 39 drives the bevel gear six 38 and the cylinder 2 to rotate, so that the cylinder 2 drives the sliding column 3 and the lifting column 4 to change the angle, so that the device can not only transport the coal mine electromechanical equipment to a suitable height, distance and position, but also can change the angle at the same time, so that the transportation range of the device is wider and the device is more practical.

[0056] When the coal mine electromechanical equipment is being transported and there is no need to change the angle, the threaded rod 2 40 is rotated to drive the adjusting block 41 and the adjusting shell 352 to move, so that the adjusting shell 352 drives the bevel gear 7 39 to move, so that the bevel gear 7 39 is disengaged from the bevel gear 6 38. At this time, the cylinder 2 is fixed. When the device is transporting the coal mine electromechanical equipment, it will not rotate to change the angle. When the angle needs to be changed, the threaded rod 2 40 is reversed to make the bevel gear 7 39 mesh with the bevel gear 6 38, making the device more flexible, convenient, and thus more practical.

[0057] By rotating the bolt 42, the bolt 42 is moved out of the thread groove 44. At this time, the locking block 43 and the adjusting shell 352 are released, so that the device is easy to replace the bevel gear 7 39, so that the device can replace the appropriate bevel gear 7 39 according to the needs. When the device is used to transport coal mine electromechanical equipment, the angle change of the device during transportation can be adjusted by replacing the bevel gear 7 39, so that it is more practical and convenient, and it is more convenient to transport coal mine electromechanical equipment at different angles.

[0058] By rotating the threaded rod three 45, since the threaded rod three 45 is threadedly connected with the bevel gear six 38, the movement of the threaded rod three 45 drives the bevel gear six 38 to move up and down, so that the bevel gear seven 39 is replaced and adjusted. If the replaced bevel gear seven 39 changes too much, it is easy to cause it to be unable to mesh with the bevel gear six 38. The rotation of the threaded rod three 45 drives the bevel gear six 38 to move up and down, so that the bevel gear six 38 and the replaced bevel gear seven 39 are replaced and fit closely, so that the replacement range of the bevel gear seven 39 is increased, thereby increasing the upper and lower limits of the angle change range of the device, making it more practical.
