Description

Technical Field

[0001] The present invention relates to the technical field of traveling blocks, and particularly to a traveling block with a new structure. Background Art

[0002] The traveling block is an important device in oil and gas drilling and workover operations. It is usually used together with elevator links and elevators to trip drill pipes, tubing, sucker rods and various drilling tools. With the development of the automation of drilling equipment, it is required to install automatic operation and limit elevator links and elevator devices, provide power to these devices, and collect signals. Currently, the power pipelines and signal lines used are provided from the outside of the traveling block. During on-site use, there are often dangerous situations where the pipelines are entangled with the traveling block body. The key solution is to be able to provide power to the automatic operation and limit elevator links and elevator devices and collect signals without the dangerous situation of the pipelines being entangled with the traveling block body.

[0003] Since automated equipment needs to have power pipelines, signal lines, etc., the traditional traveling block structure does not have channels for power pipelines, signal lines, etc., and it is easy to have the dangerous situation of the pipelines being entangled with the traveling block body. For this reason, we propose a traveling block with a new structure. Summary of the Invention

[0004] The purpose of the present invention is to provide a traveling block with a new structure to solve the problem in the above background art that since automated equipment needs to have power pipelines, signal lines, etc., the traditional traveling block structure does not have channels for power pipelines, signal lines, etc., and it is easy to have the dangerous situation of the pipelines being entangled with the traveling block body.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A traveling block with a new structure includes a support body and a hook rod. A connecting pipe is fixed below the support body, and an upper end cover is installed above the inside of the connecting pipe. A spring is arranged below the upper end cover, and a lower end cover is installed at the bottom of the spring. A sealing ring is clamped below the inside of the connecting pipe. The hook rod passes through the center of the inside of the connecting pipe, the center of the inside of the upper end cover, the center of the inside of the spring, the center of the inside of the lower end cover, and the center of the inside of the sealing ring respectively, and a central hole passes through the inside of the hook rod. A signal line body passes through the inside of the central hole. A rotary joint is installed in the middle of the top of the connecting pipe. The top end of the signal line body passes out of the rotary joint, and the bottom end of the signal line body passes out of one side of the bottom of the hook rod. An installation seat is connected below the hook rod, and a hook is installed below the installation seat.

[0006] Further, the upper end cover and the lower end cover are arranged opposite to each other, and the upper and lower ends of the spring are respectively clamped into the slots of the upper end cover and the lower end cover.

[0007] Further, the top end of the hook rod is welded to the inner top surface of the connecting pipe, and the bottom end of the hook rod passes through the bottom of the connecting pipe.

[0008] Further, the outer dimension of the hook rod matches the inner dimension of the lower end cover, and the inner side surface of the sealing ring is closely attached to the outer wall surface of the hook rod.

[0009] Further, one end of the signal line body extending out of the top of the rotary joint is set as the signal line fixed end, and one end of the signal line body passing through the bottom of the hook rod is set as the signal line rotary end.

[0010] Further, the bottom end of the hook rod penetrates into the interior of the mounting seat, and the bottom end of the hook rod is connected to the lifting hook.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. Compared with the traditional traveling block hook, the traveling block hook with the new structure solves the problem of winding of the pipeline channels of the automation equipment during the buffering and rotating operation of the hook body, is safe and reliable. In the traveling block hook with the new structure, a rotary joint is provided. One section of the pipeline is connected to the stator of the rotary joint, and the stator is fixed. The other section of the pipeline is connected to the rotor and extends out of the traveling block hook body through the hollow pipeline inside the hook rod. When the hook body buffers and rotates, the pipeline rotates with the hook body through the rotating device and the internal channel of the hook rod, and the winding of the pipeline will not occur.

[0013] 2. The signal line fixed end is the starting point of signal transmission, and the signal line rotary end is the ending point of signal transmission. Passing the entire signal line body through the hook rod can avoid the dangerous situation of the pipeline being wound around the traveling block hook body.

[0014] 3. The upper end cover and the lower end cover are used to install the spring, so that the spring can be stably placed in the connecting pipe and keep a coaxial relationship with the hook rod. Using the elasticity of the spring, after the hook rod moves, it has the ability to reset. And the lower end cover is snap-fitted on the outside of the hook rod and is closely connected to the hook rod, so the elastic force of the spring can be transferred to the hook rod to realize the reset control of the hook rod.

[0015] 4. The hook rod is firmly welded and suspended in the connecting pipe, the structural connection is tight and not easy to loosen. The bottom end of the hook rod passes through for the purpose of connecting the lifting hook. By the vertical movement of the hook rod, the lifting hook is controlled to lift, so that the lifting hook completes the work of hooking. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution: a traveling block hook with a new structure, including a support body 1 and a hook rod 7. A connecting pipe 2 is fixed below the support body 1, and an upper end cover 3 is installed above the inside of the connecting pipe 2. A spring 4 is arranged below the upper end cover 3, and a lower end cover 5 is installed at the bottom of the spring 4. The upper end cover 3 and the lower end cover 5 are arranged opposite to each other, and both the upper and lower ends of the spring 4 are respectively clamped into the slots of the upper end cover 3 and the lower end cover 5. The upper end cover 3 and the lower end cover 5 are used to install the spring 4, so that the spring 4 can be stably placed in the connecting pipe 2 and kept coaxial with the hook rod 7. Using the elasticity of the spring 4, after the hook rod 7 moves, it has the ability to reset;

[0021] A sealing ring 6 is clamped below the inside of the connecting pipe 2. The hook rod 7 passes through the center of the inside of the connecting pipe 2, the center of the inside of the upper end cover 3, the center of the inside of the spring 4, the center of the inside of the lower end cover 5, and the center of the inside of the sealing ring 6 respectively. A central hole 8 is penetrated inside the hook rod 7. The top end of the hook rod 7 is welded to the inner top surface of the connecting pipe 2, and the bottom end of the hook rod 7 passes out from the bottom of the connecting pipe 2. The hook rod 7 is firmly welded and hung in the connecting pipe 2, with a tight structural connection and not easy to loosen. The purpose of the bottom end of the hook rod 7 passing out is to connect the hook 14. The outer dimension of the hook rod 7 matches the inner dimension of the lower end cover 5, and the inner side surface of the sealing ring 6 is closely attached to the outer wall surface of the hook rod 7. The lower end cover 5 is clamped outside the hook rod 7 and is tightly connected to the hook rod 7. Therefore, the elastic force of the spring 4 can be transferred to the hook rod 7 to realize the reset control of the hook rod 7. The sealing ring 6 is used to ensure the tight connection between the hook rod 7 and the connecting pipe 2;

[0022] The inside of the central hole 8 runs through with a signal line body 9. A rotary joint 10 is installed in the middle of the top of the connecting pipe 2. The top end of the signal line body 9 passes through the rotary joint 10, and the bottom end of the signal line body 9 passes through one side of the bottom of the hook rod 7. One end of the signal line body 9 extending out of the rotary joint 10 at the top is set as a signal line fixed end 11, and one end of the signal line body 9 passing through the hook rod 7 at the bottom is set as a signal line rotating end 12. The signal line fixed end 11 is the starting point of signal transmission, and the signal line rotating end 12 is the ending point of signal transmission. Passing the signal line body 9 entirely through the hook rod 7 can avoid the dangerous situation of the pipeline winding around the traveling block hook body. A mounting seat 13 is connected below the hook rod 7, and a lifting hook 14 is installed below the mounting seat 13. The bottom end of the hook rod 7 penetrates into the inside of the mounting seat 13, and the bottom end of the hook rod 7 is connected to the lifting hook 14. By vertically moving the hook rod 7, the lifting hook 14 is controlled to be lifted, so that the lifting hook 14 completes the hooking work.

[0023] For this type of traveling block hook, first install the traveling block hook on the automated equipment, connect the signal line fixed end 11 of the signal line body 9 to the starting point of signal transmission, and connect the signal line rotating end 12 to the ending point of signal transmission. Then, the actions of the traveling block hook can be used to realize the up and down control of drill pipes, tubing, sucker rods and various drilling tools, that is, by moving the hook rod 7, the lifting hook 14 at its bottom is driven to perform an opening and closing movement, so as to achieve the hooking purpose. When the hook rod 7 moves, the spring 4 is stretched and elongated, and thus has an elastic reset tendency. On this basis, the hook rod 7 can be quickly reset, so as to hook the above-mentioned drill pipes, tubing, sucker rods and various drilling tools, and realize the lifting purpose of the drill pipes, tubing, sucker rods and various drilling tools.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
