[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them.

[0022] A circular hole is drilled on the surface with a drilling device to enter the underground oil layer, and then the drilling work is carried out with a drill bit. After the drilling is completed, the drill bit can be salvaged with a drill bit salvage device.

[0023] In the related art, the drill bit is clamped and fixed by setting a clamp and a rotating mechanism. Although it can clamp and fix the drill bit well, in actual use, the rotating mechanism is relatively complicated and the clamping force is unstable, resulting in poor fixing effect. It also cannot ensure that the clamping surface of the clamp and the outer side of the drill bit are closely fitted, which affects normal use and brings inconvenience to the drill bit salvage work.

[0024] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an oil drilling drill bit salvage device. When it is needed, it is only necessary to turn on the driving mechanism 22, so that the clamping block 27 clamps the drill bit to fix the drill bit. It is more convenient and quick, and improves the convenience of the device.

[0025] The present application is described below with reference to the accompanying drawings and specific embodiments: Combination Figure 1-Figure 3 The embodiment of the present application provides a salvaging device for a petroleum drilling drill bit, comprising a salvaging component 1: a steel cable 11, one end of which is provided with a fixing component 2; a magnetic block 12, one end of the steel cable 11 is connected to the magnetic block 12 through the fixing component 2; the fixing component 2 comprises: a box 21, which is arranged at the bottom end of the steel cable 11, and the magnetic block 12 is fixedly connected to the bottom of the box 21; a driving mechanism 22, which is arranged inside the steel cable 11; a rod 23, which is rotatably connected to the box 21, and the driving mechanism 22 is used to adjust the angle of the rod 23; a frame 24, which is fixedly connected to the outside of the rod 23; a clamping plate 25, which is fixedly connected to one end of the frame 24; a connecting seat 26, which is arranged at the bottom end of the clamping plate 25; and a clamping block 27, which is rotatably connected to the connecting seat 26.

[0026] When in use, the steel cable 11 is lowered by a cable pulling machine. When encountering a bend, the steel cable 11 can be slightly bent and passed through by the overall weight of the device. Then, when the magnetic block 12 contacts the drill bit, the drill bit is adsorbed by the magnetic block 12. After the adsorption is completed, the driving mechanism 22 is turned on. The box 21 is provided with a power supply and a receiving and control module. After the cable passes through the rope, it is connected to the external switch. By turning on the driving mechanism 22 (the driving mechanism 22 is composed of a motor and a gear set, and the gear set is composed of a plurality of mutually meshing gears, the motor is turned on to rotate a gear, and then the two rod bodies 23 are rotated in opposite directions through gear transmission), the two rod bodies 23 drive the two frames 24 to rotate, thereby rotating the two clamps 25 and the two clamping blocks 27. After the clamping blocks 27 contact the drill bit, the frame 24 continues to apply force to rotate the clamping blocks 27 on the connecting seat 26 and clamp with the drill bit. Then, the steel cable 11 is pulled upward by the cable pulling machine, and the drill bit can be taken out through the magnetic block 12 and the clamping block 27.

[0027] In some embodiments, the fixing assembly 2 further includes: a counterweight block 28, which is disposed at the bottom of the clamp block 27. When in use, the clamp block 27 is always in a relatively vertical state, so as to facilitate close contact with the drill bit.

[0028] In some embodiments, the center of the clamp block 27 is located below the connecting seat 26, so that when the frame 24 rotates, the clamp block 27 can rotate on the connecting seat 26 due to its own gravity.

[0029] In some embodiments, a disassembly assembly 3 is provided at one end of the steel cable 11; the disassembly assembly 3 includes: a connecting block 31, fixedly connected to one end of the steel cable 11, and the connecting block 31 is inserted into the box body 21; a round head rod 32, slidably connected to the outside of the connecting block 31; a spring 33, sleeved on the outside of the round head rod 32, and the two ends of the spring 33 are respectively fixedly connected to the box body 21 and the spring 33, and one end of the round head rod 32 is inserted into the connecting block 31.

[0030] When in use, the round-headed rod 32 is pulled outward to make one end of it slide out from the connecting block 31, and then the spring 33 is squeezed to pull the box body 21 downward to separate it from the connecting block 31, thereby completing the disassembly of the box body 21 and the structure thereon, and vice versa for installation.

[0031] In some embodiments, a sliding assembly 4 is provided on the outside of the box body 21; the sliding assembly 4 includes: a shell 41, fixedly connected to the outside of the box body 21; a rod body 42, slidably connected to the shell body 41; a spring 43, provided in the shell body 41, and the two ends of the spring 43 are respectively fixedly connected to the rod body 42 and the shell 41.

[0032] During use, when disassembly is required, the driving mechanism 22 is used to rotate the frame 24 outward, so that the frame 24 contacts the rod 42, and then the driving mechanism 22 is continued to be used to make the frame 24 push the rod 42 to slide upward in the shell 41 while squeezing the spring 43, and then the top of the rod 42 contacts the round head rod 32 and pushes the round head rod 32 to slide outward, thereby canceling the lock between the connecting block 31 and the box body 21, facilitating subsequent disassembly.

[0033] In some embodiments, the sliding assembly 4 further includes: a round-headed rod 44 slidably connected to the rod body 42 . When in use, the round-headed rod 44 limits the rod body 42 to only slide longitudinally and also serves as a limit for the spring 43 .

[0034] In some embodiments, a chamfer is provided on the outer side of the round head rod 32 , and when the rod body 42 slides upward, the rod body 42 pushes the round head rod 32 to slide outward by contacting the chamfer.

[0035] In some embodiments, both ends of the rod body 42 are provided with rounded corners to reduce the contact area between the rod body 42 and the frame body 24 without affecting the frame body 24 pushing the rod body 42, thereby increasing the service life.

[0036] In some embodiments, a sealing gasket is disposed on the box body 21 , and the sealing gasket is in contact with the outer side of the rod body 23 to prevent liquid from entering the box body 21 through a gap between the rod body 23 and the box body 21 .

[0037] In some embodiments, the driving mechanism 22 is composed of a motor and a gear set. When in use, the motor is turned on to rotate a gear, and then the two rods 23 are rotated in opposite directions through gear transmission.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0039] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
