[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of 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. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0023] In the description of this application, it should be noted that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the invented product is usually placed when in use. These are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0024] In addition, in this application, unless otherwise expressly specified or limited, the phrase "a first feature is above or below a second feature" may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, the phrases "above, above, and above the second feature" may include the first feature being directly above and obliquely above the second feature, or simply indicate that the first feature is higher in level than the second feature. The phrases "below, below, and below the second feature" may include the first feature being directly below and obliquely below the second feature, or simply indicate that the first feature is lower in level than the second feature.

[0025] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0026] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] Example:

[0028] Please refer to Figure 1 , with reference Figure 2The present application provides a special directional broken drill pipe finding connector, which mainly includes a salvage rod body 1, a pull-back U-shaped hook 2, a reinforcing rib plate 3 and a positioning U-shaped hook 4; wherein, one side wall of the positioning U-shaped hook 4 is installed on one side of the salvage rod body 1; at the same time, the pull-back U-shaped hook 2 and the positioning U-shaped hook 4 are both U-shaped structures, and one side end of the pull-back U-shaped hook 2 away from the U-shaped opening is connected to the one side end of the positioning U-shaped hook 4 away from the U-shaped opening at an angle; the two opposite side walls of the reinforcing rib plate 3 are respectively connected to one side surface of the pull-back U-shaped hook 2 and one side surface of the positioning U-shaped hook 4.

[0029] It should be noted that, in this embodiment, the length of the fishing rod body 1 is longer than the length of the positioning U-shaped hook 4 and the length of the retracting U-shaped hook 2 .

[0030] At the same time, the length extension direction of the salvage rod body 1 is parallel to the length extension direction of the position detecting U-shaped hook 4 , and the U-shaped opening direction of the position detecting U-shaped hook 4 is the same as the length extension direction of the position detecting U-shaped hook 4 .

[0031] It should be noted that in this embodiment, the salvage rod body 1 is fixedly connected to the position-finding U-shaped hook 4. The pullback U-shaped hook 2 and the position-finding U-shaped hook 4 can be fixedly connected. Furthermore, the reinforcing rib 3 is fixedly connected to both the pullback U-shaped hook 2 and the position-finding U-shaped hook 4. Furthermore, the pullback U-shaped hook 2 and the position-finding U-shaped hook 4 can be arranged at an included angle or an obtuse angle.

[0032] It should be noted that, in this embodiment, the cross section of the reinforcing rib plate 3 is triangular.

[0033] It should be noted that, in this embodiment, the structures and dimensions of the retraction U-shaped hook 2 and the position detection U-shaped hook 4 may be the same; in other embodiments, the dimensions of the two may also be different.

[0034] The tool operates as follows:

[0035] Step 1: When using, first lower the large hook composed of the pull-back U-shaped hook 2, the reinforcing rib plate 3 and the positioning U-shaped hook 4 in the device, and use the excavator to vertically insert the entire large hook into the broken drill rod 5 area to find the specific location of the broken drill rod 5;

[0036] Step 2: After the broken drill rod 5 is touched, the rod body 1 is salvaged and exposed to the ground. The excavator is used to rotate the entire device 90 degrees in situ;

[0037] Step 3: Insert the device downward again to a position beyond the broken drill rod 5, and rotate it 90 degrees in reverse on the spot so that the U-shaped opening of the positioning U-shaped hook 4 is facing the broken drill rod 5;

[0038] Step 4: Use a crane to lift the entire salvage rod body 1 so that the positioning U-shaped hook 4 can first hook the broken drill rod 5;

[0039] Step 5: After hooking the broken drill rod 5, use the excavator to slowly lower the device toward the drilling rig (at this time, pull back the U-shaped hook 2 and slowly clamp the broken drill rod 5) until it is tilted onto the drilling rig and the drill rod can be connected to the device;

[0040] Step 6. After the drilling rig is connected to the device, the drilling rig trolley moves backward and pulls back the U-shaped hook 2 to slowly slide along the broken drill rod 5 to the step of the broken drill rod 5. After the step at the joint of the broken drill rod 5 is stuck, the drilling rig starts to increase the force to slowly drag the broken drill rod 5 out of the ground, and the salvage work is completed.

[0041] In summary, the present invention's dedicated directional drill rod retrieval connector can quickly connect a broken drill rod 5 after it breaks near the ground, allowing it to be quickly pulled out of the ground, thus reducing engineering losses. The device has a simple structure, is easy to use, has high salvage efficiency, is safe and reliable, has low construction costs, is easy to operate, and saves time and effort.

[0042] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
