[0035] People press the main power switch to power on the device. When people need to salvage the drill bit in the deep well, they first move the device to the deep well where the drill bit needs to be salvaged. People manually push the device and move it to the deep well by rotating the wheel 1. The buffer spring 3 can play a buffering role during movement. When the device moves to the top of the deep well, people stop pushing the device and manually open the trigger switch 87. The trigger switch 87 sends a signal. The control module receives the signal to control the first electric push rod 74, the first drive motor 83 and the electromagnet 89 to start working. The telescopic rod of the first electric push rod 74 drives the first fixed block 73 to move downward, and then drives the first guide wheel 75 and the sliding rod 72 to move downward, so that the angle of the middle steel cable 810 becomes larger, so as to achieve the purpose of saving time and effort.

The control module receives the signal to control the first drive motor 83 and the electromagnet 89 to stop working, and at the same time controls the first electric push rod 74 to start for 5 seconds. The telescopic rod of the first electric push rod 74 drives the first fixed block 73, the first guide wheel 75 and the sliding rod 72 to reset. The first electric push rod 74 runs for 5 seconds and automatically shuts down.

[0036] Example 2

[0037] On the basis of Example 1, Figure 6-10 As shown, an anti-swing mechanism 9 is also included, which includes a guide frame 91, a push plate 92 and a clamping block 93. The guide frame 91 is symmetrically arranged in the front and back of the middle part of the bottom plate 4, and the push plate 92 is slidably connected to the inside of the guide frame 91. The push plate 92 is provided with a clamping block 93 on the inner side of the upper part.

[0038] It also includes a driving mechanism 10, which includes a distance sensor 101, a rack rod 102, a second driving motor 103 and a first gear 104. The distance sensor 101 is provided on the rear lower side of the rear push plate 92, and the rack rods 102 are symmetrically provided on the lower side of the push plate 92. The rack rods 102 are slidingly connected to the guide frame 91 on the same side. A second driving motor 103 is provided on the left side of the top of the bottom plate 4, and a first gear 104 is symmetrically rotatably provided in the middle of the top of the bottom plate 4. The first gears 104 cooperate with the rack rod 102 on the same side, and the output shaft of the second driving motor 103 is connected to the first gear 104 on the left side.

[0039] People manually turn on the trigger switch 87, the trigger switch 87 sends a signal, the control module receives the signal and controls the second drive motor 103 to start, the output shaft of the second drive motor 103 drives the first gear 104 on the left to rotate, and then drives the rack rod 102 and the push plate 92 to move, the rack rod 102 drives the first gear 104 on the right to rotate, the push plate 92 drives the distance sensor 101 and the block 93 to move outward, so that the block 93 is separated from the lock 88, the distance sensor 101 detects that the distance between the guide frame 91 on the rear side is shortened and sends a signal, the control module receives the signal and controls the second The driving motor 103 is turned off, and the lock buckle 88 drives the electromagnet 89 and the first pressure sensor 811 to move downward. The first pressure sensor 811 sends a signal after detecting the pressure. The control module receives the signal to control the second driving motor 103 to reverse and start. When the lock buckle 88 moves upward to reset, the lock buckle 88 contacts the block 93. The block 93 can prevent the lock buckle 88 from swinging during the resetting process to prevent the drill bit from being thrown away. The distance sensor 101 detects that the distance between the guide frame 91 on the rear side is elongated and sends a signal. The control module receives the signal to control the second driving motor 103 to stop working.

[0040] The anti-falling mechanism 11 includes a second bracket 1101, a guide plate 1102, a second pressure sensor 1103, a second electric push rod 1104, a third drive motor 1105, a second gear 1106, a rotating shaft 1107, a third gear 1108 and a limit rod 1109. The second brackets 1101 are symmetrically arranged on both sides of the top of the bottom plate 4. The guide plates 1102 are arranged between the upper parts of the second brackets 1101 on the same side vertically. The second pressure sensor 1103 is arranged on the left rear side of the right guide plate 1102. A second electric push rod 1104 is provided at the bottom of the guide plate 1102, a slider is slidably connected inside the guide plate 1102, the telescopic rod of the second electric push rod 1104 is connected to the slider, a third driving motor 1105 is provided on the top of the slider, the output shafts on the front and rear sides of the third driving motor 1105 are connected to the second gear 1106, the upper part of the guide plate 1102 is rotatably connected to the rotating shaft 1107, the rotating shaft 1107 is symmetrically provided with third gears 1108, and a limiting rod 1109 is connected between the front and rear sides of the rotating shaft 1107.

[0041] After the device is powered on, the control module controls the distance sensor 101 to work. When the push plate 92 drives the distance sensor 101 to reset, the distance sensor 101 detects that the distance between it and the guide frame 91 on the rear side is lengthened and then sends a signal. The control module receives the signal to control the second electric push rod 1104 and the third drive motor 1105 to start. The telescopic rod of the second electric push rod 1104 drives the slider to move upward and then drives the third drive motor 1105 to move upward. The output shaft of the third drive motor 1105 drives the second gear 1106 to rotate. When the second gear 1106 moves upward to engage with the third gear 1108, it drives the third gear 1108 to rotate. At the same time, the second electric push rod 1104 runs for 5 seconds and then closes automatically. The rotation of the third gear 1108 drives the limit rod 1109 to rotate downward, so that the limit rod 1109 presses the steel cable 810. At this time, due to the heavy object hanging on the steel cable 810, the second pressure sensor 1103 reaches the first preset value. The second pressure sensor 1103 detects After reaching the pressure, a signal is sent out, and the control module receives the signal to control the third drive motor 1105 to stop working. When the heavy object suddenly falls off during the ascent, the pressure of the steel cable 810 on the limit rod 1109 is reduced, causing the pressure of the second pressure sensor 1103 to increase and reach the second preset value. The second pressure sensor 1103 detects that the pressure has reached the limit and sends a signal. The control module receives the signal to control the second electric push rod 1104 to start, and the telescopic rod of the second electric push rod 1104 drives the slider to move downward and then drives the third drive motor 1105 to move downward. The third drive motor 1105 drives the second gear 1106 to move downward, so that the second gear 1106 is separated from the third gear 1108. The second electric push rod 1104 closes automatically after running for 5 seconds. At this time, due to gravity, the electromagnet 89 and the lock 88 move downward rapidly, making the steel cable 810 straight, driving the limit rod 1109 to move upward and reset. In this way, people can observe whether the drill bit has fallen. After the drill bit falls, the equipment needs to be restarted.

[0042] It also includes a supporting mechanism 12, which includes a third electric push rod 1201, a fourth electric push rod 1202 and a force plate 1203.

The telescopic rod of the fourth electric push rod 1202 drives the force plate 1203 to move downward for 5 seconds and then automatically closes. At this time, the force plate 1203 is in contact with the ground, so that the equipment can be supported when salvaging the drill bit, and the equipment can be prevented from shaking when the drill bit falls off during the rising process. After the salvage is completed, people close the trigger switch 87, and the trigger switch 87 sends a signal to control the third electric push rod 1201 and the fourth electric push rod 1202 to reset, and the fourth electric push rod 1202 drives the force plate 1203 to reset.
