Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-11 The present invention provides a technical solution:

[0032] Example 1,

[0033] A deep foundation pit operation support system includes:

[0034] The frame 1 has a winch 21 mounted on its top. The top of the winch 21 is fitted onto the outer wall of the support rod 23 via a collar 22. Both sides of the support rod 23 are fixed to the side wall of the frame 1. A hand crank 24 is fixed to the side of the frame 1. A monitor 26 is connected to the bottom of the hand crank 24 via a pull rope 25.

[0035] Rescue mechanism 3 is provided on the side of the winch 21 to enable synchronous rescue by bringing the winch 21 and hand crank 24 close together. Rescue mechanism 3 includes a movable base 31 fixed to the side wall of the winch 21, with a screw 32 threadedly connected internally to the movable base 31. The outer end of the screw 32, away from the movable base 31, is threadedly connected to a connecting frame 33. The bottom of the connecting frame 33 is fixed to the side wall of a slider 34, which is inserted into a limiting plate 35. The top of the hand crank 24 is fixed to the bottom of the limiting plate 35. After the construction personnel enter the pit, they activate the rope sensor inside the monitor 26, and the monitor 26 begins to operate. When a construction personnel faints and falls, the monitor 26 detects the binding... If the worker's pull rope 25 is suddenly pulled, indicating that the worker is in danger, the monitor 26 will transmit a signal to the controller. The controller will then control the motor 38 to operate. The motor 38 will rotate forward, and with the help of the threads on the outer wall of the motor 38, the rotation of the motor 38 will drive the moving seat 31 and the connecting frame 33 to move synchronously in opposite directions. The moving seat 31 will drive the winch 21 to move synchronously, and the connecting frame 33 will drive the hand crank 24 to move synchronously. This will allow the winch 21 and the hand crank 24 to move closer to each other, which will facilitate the approach of the hanging rope and pull rope 25 connected to the winch 21. The hanging rope and pull rope 25 connected to the winch 21 will then be used to simultaneously hook and attach the worker. The two sets of hooks will make the rescue of the worker more stable and safe.

[0036] The slider 34 is set in the shape of "I". The limiting plate 35 has a limiting port 36 inside that cooperates with the slider 34. The top of the limiting plate 35 is fixed to the frame 1 through the connecting plate 37. The slider 34 slides more stably in the limiting port 36. The limiting port 36 limits the slider 34, so that the connecting frame 33 drives the hand crank 24 to move more smoothly and stably through the slider 34.

[0037] The monitor 26 has a slide plate 41 fixed to its side wall, and slide plate 41 is slidably connected to slide plate 42. The side wall of slide plate 42 is fixedly connected to the frame 1. The movement of the monitor 26 is limited by slide plate 41, so that the sliding of slide plate 41 on the surface of slide plate 42 is more stable, thereby guiding the movement of the monitor 26 and making the monitor 26 move more stably with the hand crank 24.

[0038] One end of screw 32 is fixedly connected to the output shaft of motor 38, and the end face of motor 38 is fixed to the surface of fixed block 43. The top of fixed block 43 is fixed to the side wall of frame 1. The other end of screw 32 is movably connected to fixed block 44 via movable shaft 1, and the top of fixed block 44 is fixed to the side wall of frame 1. After receiving the signal monitored by monitor 26, the controller controls motor 38 to work. The operation of motor 38 drives screw 32 to rotate. The rotation of screw 32 realizes the synchronous movement of moving seat 31 and connecting frame 33. The fixed block 43 and fixed block 44 realize the stable connection of screw 32, making the operation of screw 32 more stable.

[0039] The end face of the winch 21 drum is wound with a pull rope 2 45, and the bottom of the pull rope 2 45 is fixed with a connecting block 46. The side of the connecting block 46 is provided with a magnet 47 that cooperates with the electromagnet 63. The electromagnet 63 is fixed to the surface of the fixing block 3 62, and the fixing block 3 62 is fixed to the outer wall of the protective belt 27. The bottom of the connecting block 46 is fixed with a connecting rod 1 48, and the two sides of the outer wall of the connecting rod 1 48 are fixed with hooks 49. When the hook 49 is close to the construction worker, the controller energizes the electromagnet 63. After the electromagnet 63 is energized, it generates magnetism. The electromagnet 63 and the magnet 47 attract each other. By hooking the construction worker with the pull rope 1 25 through the hook 49, the unconscious construction worker can be rescued from the pit, thus realizing the rescue of the unconscious construction worker.

[0040] If a construction worker faints and the excavation tool pins the worker against the inner wall of the pit, the monitor 26 will not detect the fainting. The monitor will contact the worker via a call button. If the worker cannot respond and the hoisting bucket does not contain any gravel, the ground staff will determine that the worker has fainted and manually operate the switch of motor 38 to start the rescue.

[0041] Example 2,

[0042] A connecting rod 2 51 is fixed to the bottom of the connecting block 46, and a motor 2 52 is fixed to the bottom of the connecting rod 2 51. The output shaft of the motor 2 52 is fixedly connected to the screw 2 53, and a connecting rod 3 54 is fixed to the bottom of the screw 2 53. A limit plate 2 55 is fixed to the bottom of the connecting rod 3 54, and rotating hooks 56 are movably connected to both sides of the outer wall of the connecting rod 3 54. A fixing plate 57 is fixed to the top of the rotating hooks 56, and a rotating plate 58 is movably connected to the top of the fixing plate 57 through a movable shaft 2. The top of the rotating plate 58 is movably connected to a threaded sleeve 1 59 through a movable shaft 3. The threaded sleeve 1 59 is threaded onto the screw 2 53. On the outer wall, after the construction worker faints, the connecting block 46 moves towards the construction worker. When the connecting block 46 moves to the bottom of the pit, the controller controls the second motor 52 to work. The second motor 52 works, causing the second screw 53 to rotate forward. The rotation of the second screw 53 causes the first screw sleeve 59 to move down. The movement of the first screw sleeve 59 drives the rotating plate 58 to move down synchronously. The movement of the rotating plate 58 pushes the rotating hook 56 to rotate through the fixed plate 57. The rotating hook 56 rotates downward, and the lifting bucket suspended by the rotating hook 56 falls off, which facilitates the timely detachment of the lifting bucket. This makes it easier for the rotating hook 56 to approach the construction worker in time to rescue the construction worker and speed up the rescue.

[0043] Limiting rods 61 are inserted on both sides of the screw sleeve 59. The top end of the limiting rod 61 is fixed to the surface of the connecting rod 51, and the bottom end of the limiting rod 61 is fixed to the surface of the connecting rod 54. The screw sleeve 59 is limited by the limiting rods 61, so that the vertical movement of the screw sleeve 59 is more stable.

[0044] Example 3,

[0045] The connecting rod 3 54 is equipped with clamping plates 64 on both sides. The upper end of the side wall of the clamping plate 64 is fixed with a hanging rod 65 that limits the rotation hook 56, and the lower end of the side wall of the clamping plate 64 is fixed with a hanging rod 66 that limits the limiting plate 2 55. When the rotation hook 56 is close to the rope 28, the clamping plate 64 moves closer to the connecting rod 3 54. The four sets of hanging rods 2 66 are inserted into the top of the limiting plate 2 55, and the four sets of hanging rods 1 65 are inserted into the top of the rotation hook 56. When the pull rope 2 45 is pulled up, the rotating hook 56 and the limiting plate 2 55 are hooked by the hanging rods 1 65 and 2 66 respectively, so as to suspend the construction personnel and make the rescue of the construction personnel more stable.

[0046] The outer walls of the clamping plates 64 are all fixed with threaded sleeves 67. The two sets of threaded sleeves 67 are threadedly connected to the screw rod 68. One end of the screw rod 68 is fixedly connected to the output shaft of the motor 72. The outer wall of the motor 72 is fixed with a fixing block 73, which is fixed to the surface of the rope 28. The rope 28 is fixed to the middle of the protective belt 27. The other end of the screw rod 68 is movably connected to the fixing block 74, which is fixed to the surface of the rope 28. When the motor 72 is working, the screw rod 68 rotates to move the two sets of clamping plates 64. The clamping plates 64 slide on the surface of the rope 28. The two sets of clamping plates 64 limit the connection rod 54, so that the connection rod 54 is fixedly connected to the rope 28.

[0047] A linkage switch 71 is fixed on the surface of magnet 47, and the output end of linkage switch 71 is electrically connected to the input end of motor 3 72 through a wire. Linkage switch 71 controls motor 3 72 to work. When electromagnet 63 is attracted to magnet 47, linkage switch 71 is squeezed by electromagnet 63. Linkage switch 71 controls motor 3 72 to work, so that after magnet 47 and electromagnet 63 are connected, the opening of linkage switch 71 indirectly realizes the connection and binding of connecting rod 3 54 and rope 28, which is conducive to pulling rope 1 25 to pull up rescue construction personnel.
