DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] See also Figures 1 to 8 The present invention provides a technical solution: an automatic reeling and unreeling device for geophysical exploration, comprising a mounting frame 1 and a reeling roller 2 for reeling in a cable, the two ends of the reeling roller 2 are fixedly connected with connecting plates 30, the ends of the connecting plates 30 are fixedly provided with rotating shafts 3 that penetrate through the mounting frame 1 and are rotatably connected, one end of the rotating shaft 3 is fixedly connected with a bevel gear 4, the bevel gear 4 is transmission-connected with a transmission shaft 5, the end of the transmission shaft 5 is sleeved with a connecting sleeve 10, the end of the connecting sleeve 10 away from the bevel gear 4 is transmission-connected with a drive shaft 6, the opposite end of the drive shaft 6 and the connecting sleeve 10 is fixedly connected with a friction disc 7, and a protective mechanism for preventing the power mechanism from being stuck is provided on the mounting frame 1;

[0029] The protection mechanism includes a fixed frame 8 fixedly connected to the outer wall of the mounting frame 1, a rectangular frame 9 with limited sliding is arranged on the fixed frame 8, a push rod 16 for pushing the two friction discs 7 to separate is fixedly connected to one side of the rectangular frame 9, a tooth plate 15 is fixedly connected to the upper surface of the rectangular frame 9, and a gear 14 14 meshing with the tooth plate 15 is fixedly connected to the side of the connecting sleeve 10 close to the friction disc 7 for fixed axis rotation.

[0030] When the surveying instrument is obstructed and cannot be lifted normally, the load on the motor increases rapidly, causing it to get stuck. The gear four 14 rotates, and the toothed plate 15 fixed on the rectangular frame 9 and meshing with the gear four 14 moves. When the rectangular frame 9 moves, the push rod 16 fixedly connected to the rectangular frame 9 pushes the friction disk 7 on the connecting sleeve 10 to separate from the friction disk 7 on the drive shaft 6. At this time, the motor rotates at no load, thereby protecting the motor and preventing the motor from being subjected to excessive load for a long time and burning the motor.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 An operating rod 12 is provided on the outer wall of the fixed frame 8 and is coaxially fixedly connected to the gear four 14. A spline 11 is fixedly connected to the outer contour of the transmission shaft 5 and is axially limited and slidably connected to the inner wall of the connecting sleeve 10. The push rod 16 is arranged in an arc shape near one end of the connecting sleeve 10, and an annular groove 31 is provided on the outer contour of the connecting sleeve 10 and is slidably connected to the end of the push rod 16.

[0032] A spline 11 is fixedly connected to the outer contour of the transmission shaft 5 and is axially limited and slidably connected to the inner wall of the connecting sleeve 10. The spline 11 can enable axial sliding between the transmission shaft 5 and the connecting sleeve 10, thereby facilitating the separation of the friction disc 7 on the connecting sleeve 10 and the friction disc 7 on the drive shaft 6.

[0033] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 Two limit blocks 23 are fixedly connected to one side of the outer wall of the mounting frame 1 near the fixing frame 8, through which the transmission shaft 5 and the driving shaft 6 pass and are fixedly connected for rotation. One end of the transmission shaft 5 near the bevel gear 1 4 is coaxially fixedly connected to the bevel gear 2 13 meshing with the bevel gear 1 4. The end of the driving shaft 6 away from the friction disk 7 is fixedly connected to a power mechanism that drives the winding roller 2 to rotate and automatically retract and release the wire.

[0034] The power mechanism is a worm gear reduction motor, which is fixedly connected to the drive shaft 6 through the output shaft of the worm gear reduction motor. When the two friction plates 7 contact each other, the forward and reverse rotation of the worm gear reduction motor is controlled to drive the transmission shaft 5 to rotate. The transmission shaft 5 is connected to the bevel gear 4 through the transmission shaft 5, which can rotate the bevel gear 4 and drive the connecting disk 30 fixedly connected to the rotating shaft 3 and the winding roller 2 to rotate, so as to automatically reel in and release the cable.

[0035] Embodiment 2

[0036] On the basis of the first embodiment, further:

[0037] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 A connecting column 32 is fixedly connected to one side of the rectangular frame 9 near the outer wall of the mounting frame 1 and extends through the mounting frame 1 to the connecting plate 30. A locking strip 17 is fixedly connected to the end of the connecting column 32. The surface of the connecting plate 30 near one end of the locking strip 17 on the winding roller 2 is provided with a circular array of locking strips 17 and mounting strips 18 that are locked together.

[0038] A connecting column 32 extending through the mounting frame 1 to the connecting disk 30 is fixedly connected to the rectangular frame 9 on one side close to the outer wall of the mounting frame 1. When the rectangular frame 9 moves on the fixing frame 8, the connecting column 32 fixedly connected to the rectangular frame 9 can be moved, and the locking bar 17 fixedly connected to the end of the connecting column 32 moves toward the connecting disk 30. The locking bar 17 arranged on the connecting disk 30 contacts the mounting bar 18, so that the connecting disk 30 can be locked to prevent the exploration equipment from pulling the rope of the winding roller 2 to automatically release the line under the action of gravity when the two friction disks 7 are separated, causing the exploration equipment to fall and be damaged.

[0039] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The ends of the mounting strip 18 away from the center of the connecting plate 30 are provided with inclined surfaces on both sides, and a sliding groove for the connecting column 32 to slide horizontally is provided on the outer wall of the mounting frame 1, and the ends of the locking strip 17 are provided with inclined surfaces that cooperate with the mounting strip 18.

[0040] The ends of the mounting strip 18 away from the center of the connecting plate 30 are provided with inclined surfaces on both sides, and the ends of the locking strip 17 are provided with inclined surfaces that cooperate with the mounting strip 18. When the locking strip 17 slides in a limited position in the horizontal direction, it is convenient for the locking strip 17 to be inserted between the two mounting strips 18 to lock the connecting plate 30.

[0041] Embodiment 3

[0042] On the basis of the second embodiment, further:

[0043] See also Figure 4 , Figure 6 and Figure 7 A support plate 21 is fixedly connected between the inner walls of the mounting frame 1, and an adjustment mechanism for automatically adjusting the cable on the winding roller 2 is arranged on the support plate 21. The adjustment mechanism includes a limit plate 22 fixed on the support plate 21, and a limit groove in a vertical direction is opened on the surface of the limit plate 22, and a sliding block 28 is connected to the limit groove for limited sliding. An installation groove is opened on the upper surface of the sliding block 28, and a pulley 29 for sleeved cables is connected to the installation groove through a fixed axis rotation.

[0044] The sliding block 28 moves in the limiting groove opened in the vertical direction on the surface of the limiting plate 22. When the sliding block 28 moves from the highest point to the lowest point, the rope pulling the surveying instrument can be loosened, and then the rope can be tightened again. By loosening and tightening the rope, the rope can be shaken, which facilitates the separation of the surveying instrument from the obstacle and realizes automatic adjustment of the obstruction state.

[0045] See also Figure 4 , Figure 6 and Figure 7 A toothed plate 2 19 is fixedly connected to the surface of the inner wall of the rectangular frame 9, and a gear 3 20 is meshed on the toothed plate 19 and is transmission-connected to the sliding block 28. A connecting shaft 25 is penetrated by and fixedly rotatably connected to the mounting frame 1 and is coaxially fixedly connected to the gear 3 20. A rotating disk 26 is fixedly connected to the end of the connecting shaft 25 near the limit plate 22, and a movable rod 27 is rotatably connected to the surface of the rotating disk 26 near the limit plate 22. One end of the movable rod 27 is rotatably connected to the eccentric column on the rotating disk 26, and the other end of the movable rod 27 is rotatably connected to the rotating column on the sliding block 28.

[0046] The tooth plate 2 19 on the rectangular frame 9 is meshed with the gear 3 20. When the operating lever 12 is manually pulled to move the rectangular frame 9 on the fixed frame 8, the connecting shaft 25 coaxially fixedly connected with the gear 3 20 can be rotated. When the connecting shaft 25 rotates, the eccentric column on the surface of the connecting shaft 25 rotates, and is rotationally connected to the movable rod 27 through the eccentric column on the connecting shaft 25. The other end of the movable rod 27 is rotationally connected to the rotating column on one side of the sliding block 28. When the rotating disk 26 rotates one circle, the movable rod 27 can push the sliding block 28 to perform vertical reciprocating motion in the limiting groove opened on the surface of the limiting plate 22.

[0047] See also Figure 1 and Figure 6 A slider 24 is fixedly connected to the bottom of the rectangular frame 9, and a fixed frame 8 is located at the bottom of the rectangular frame 9 and is provided with a sliding groove for the slider 24 to slide in a limited position.

[0048] The fixing frame 8 is provided with a sliding groove at the bottom of the rectangular frame 9 for the slider 24 to slide in a limited position. By setting the slider 24 to be connected to the surface of the fixing frame 8 for limited sliding, the rectangular frame 9 can stably slide in a limited position on the surface of the fixing frame 8.

[0049] Working principle: When the automatic retractable and retractable device for geophysical exploration is in use, when the surveying instrument is obstructed and cannot be lifted normally, the load on the motor increases rapidly, causing it to get stuck. The operating rod 12 is manually pulled to rotate. The operating rod 12 is coaxially fixedly connected to the gear four 14. The rotation of the operating rod 12 can rotate the coaxially fixed gear four 14. At this time, the tooth plate 15 fixed on the rectangular frame 9 and meshing with the gear four 14 moves.

[0050] When the rectangular frame 9 moves, the spline 11 is set to enable axial sliding between the transmission shaft 5 and the connecting sleeve 10, so that the friction disk 7 on the connecting sleeve 10 is separated from the friction disk 7 on the drive shaft 6. The push rod 16 fixedly connected to the rectangular frame 9 pushes the friction disk 7 on the connecting sleeve 10 to separate from the friction disk 7 on the drive shaft 6. At this time, the motor realizes no-load rotation, thereby protecting the motor and preventing the motor from being stuck for a long time and being subjected to excessive load, which may cause the motor to burn out.

[0051] An annular groove 31 is provided on the outer contour of the connecting sleeve 10, which is slidably connected to the end of the push rod 16. When the operating rod 12 is pulled again, the transmission is transmitted through the two friction disks 7, and the output shaft of the worm gear reduction motor is fixedly connected to the drive shaft 6. When the two friction disks 7 contact each other, the forward and reverse rotation of the worm gear reduction motor is controlled to drive the transmission shaft 5 to rotate, and the bevel gear 2 13 fixedly connected to the end of the transmission shaft 5 is meshed with the bevel gear 1 4, which can make the bevel gear 1 4 rotate and drive the connecting disk 30 fixedly connected to the rotating shaft 3 and the winding roller 2 to rotate, thereby realizing automatic winding and releasing of the cable.

[0052] When the rectangular frame 9 moves on the fixed frame 8, the connecting column 32 fixedly connected to the rectangular frame 9 can be moved, and the locking strip 17 fixedly connected to the end of the connecting column 32 can move toward the connecting disk 30. The locking strip 17 arranged on the connecting disk 30 contacts the mounting strip 18, so that the connecting disk 30 can be locked to prevent the exploration equipment from pulling the rope of the winding roller 2 to automatically release the line under the action of gravity when the two friction disks 7 are separated, causing the exploration equipment to fall and be damaged. The ends of the mounting strip 18 away from the center of the connecting disk 30 are provided with inclined surfaces on both sides, and the ends of the locking strip 17 are provided with inclined surfaces that cooperate with the mounting strip 18. When the locking strip 17 slides in a limited position in the horizontal direction, it is convenient to insert the locking strip 17 between the two mounting strips 18 to lock the connecting disk 30.

[0053] The toothed plate 2 19 on the rectangular frame 9 is meshed with the gear 3 20. When the operating lever 12 is manually pulled to move the rectangular frame 9 on the fixed frame 8, the connecting shaft 25 coaxially fixedly connected with the gear 3 20 can be rotated. When the connecting shaft 25 rotates, the eccentric column on the surface of the connecting shaft 25 rotates, and the eccentric column on the connecting shaft 25 is rotatably connected to the movable rod 27. The other end of the movable rod 27 is rotatably connected to the rotating column on one side of the sliding block 28. When the rotating disk 26 rotates one circle, the movable rod 27 can push the sliding block 28 to perform vertical reciprocating motion in the limiting groove opened on the surface of the limiting plate 22, and the sliding block 28 can move in the limiting groove opened in the vertical direction on the surface of the limiting plate 22. When the sliding block 28 moves from the highest point to the lowest point, the rope pulling the surveying instrument can be loosened, and then the rope is tightened again. The rope is shaken by loosening and tightening the rope, which is convenient for separating the surveying instrument from the obstacle and realizing automatic adjustment of the obstruction state.

[0054] Although 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 may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
