Description

Technical Field

[0001] The utility model relates to the technical field of short-section drilling tool transportation, in particular to a suspension-type loading device used for short-section transportation. Background Art

[0002] Downhole power drills are core equipment and tools in oil and gas production. In recent years, the continuous improvement of my country's oil and gas drilling technology, coupled with the promotion of directional, horizontal, and multilateral wells, has further promoted the updating and advancement of downhole power drills. Downhole power drills are divided into three main types: screw drills, bladed turbine drills, and electric drills. However, as oil and gas production conditions gradually shift to complex environments such as unconventional oil and gas wells, deep wells, and deep sea, downhole power drills have placed higher demands on equipment life, operating conditions, drilling speed, controllability, and reliability. The quality of downhole power drills plays a vital role in drilling efficiency.

[0003] In the production of drilling tools, in addition to conventional drill tools ranging from 9 to 12 meters in length, short-section drill tools ranging from 1 to 3 meters are also used. However, current production line designs do not consider the handling of short-section drill tools, requiring manual transfer and handling of these short-section drill tools during production. Therefore, a technical challenge remains: how to handle these short-section drill tools without disrupting the production of conventional drill tools on the production line, thereby reducing labor intensity and improving production safety. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the above-mentioned prior art and to provide a hanging loading device for transporting short-section drill tools. The short-section drill tools are hung on the factory building and transported between different production step stations through slide rails, thereby reducing manual labor and improving production efficiency.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] According to one aspect of the utility model, a suspended loading device for transporting short-section drilling tools is provided, which is characterized in that it includes a suspended U-shaped guide rail, a short-section drilling tool, a hand-pulled mobile trolley, a trolley body, a fall chain, trolley wheels, rollers and a primer spraying plant roof.

[0007] Among them, the suspended U-shaped guide rail is placed on the roof of the primer spraying plant, connecting the space above the spraying station and the furnace entrance station; the short-section drill bit is connected by a fall chain and suspended in the lifting hole below the trolley body of the hand-pulled mobile trolley, and is moved from the spraying station to the furnace entrance station through the suspended U-shaped guide rail; the trolley wheels are installed on both sides of the trolley body and embedded in the groove of the suspended U-shaped guide rail; the roller is set at the bottom of the trolley body and contacts the lower surface outside the groove of the suspended U-shaped guide rail.

[0008] Furthermore, the suspended U-shaped guide rail is formed by welding two I-beams with a curvature radius of 2 meters and a bending angle of 90°.

[0009] Furthermore, the I-beam is 16#a I-beam.

[0010] Furthermore, the middle portion of the suspended U-shaped guide rail is located above the furnace entrance station, and the parallel portion is located above the spraying station; the end of the parallel portion is provided with a baffle for limiting the hand-pull movable trolley.

[0011] Furthermore, the tensile strength of the weld of the I-beam is 480 to 660 MPa, and the yield strength of the weld is 270 to 280 MPa.

[0012] Furthermore, the flatness tolerance of the weld of the I-beam is 0.2 mm.

[0013] Furthermore, the flatness tolerance of the planes where the inner walls of the flanges and webs of the I-beams contact the wheels and rollers of the trolley is 0.1 mm.

[0014] Furthermore, the lifting weight of the fall chain is 500 kg, the chain length is 3 m, and the lifting speed is 3 m / min.

[0015] Furthermore, both ends of the trolley body and the baffles at the end of the suspended U-shaped guide rail are paved with anti-collision rubber on the surface.

[0016] Furthermore, the length of the short drilling tool is 1m to 3m, and the lower end of the fall chain is fixed to the middle of the short drilling tool.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) Improve production efficiency: By hanging the short-section drill bit on the suspended U-shaped guide rail on the roof of the primer spraying workshop, and sliding the hand-pulled mobile trolley on the suspended U-shaped guide rail, the short-section drill bit can be moved from the spraying station to the furnace inlet station, which reduces the labor intensity, speeds up the handling process, and improves production efficiency and flexibility.

[0019] (2) Easy to implement and maintain: The suspended U-shaped guide rail is located on the roof of the primer spraying plant, which utilizes the upper space of the plant and does not require the modification of the existing conventional drilling tool production line. In addition, the device has a simple structure and is easy to implement and maintain.

[0020] (3) Strong applicability: Since the furnace inlet station of the primer spraying plant for drilling tool production is under long-term high-temperature heating conditions, this equipment is made of steel and uses a manually pulled trolley, which avoids the problem of circuit aging caused by heat when the electric control equipment is running for a long time at the heating furnace inlet. It is suitable for existing drilling tool production lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] The short-section drill bit 2 is primarily used in oil and gas drilling operations, particularly when smaller well diameters are required or special requirements for drilling depth and efficiency are in place. While shorter than standard drill bits, the short-section drill bit 2 maintains excellent strength and durability, capable of withstanding extreme operating conditions in high-pressure and high-temperature environments. Primer spraying is primarily intended to improve the adhesion and corrosion resistance of the drill bit surface. Drill bits are exposed to corrosive media such as acid and salt in underground or downhole environments. Primer provides a preliminary corrosion barrier, extending the service life of the drill bit. Furthermore, for subsequent anti-corrosion coating applications, spraying primer enhances the adhesion of the coating or other coating, reducing the risk of coating detachment or peeling. After spraying, the primer undergoes a heat treatment, typically in a high-temperature furnace, to cure the primer. This process helps the primer form a strong chemical or physical bond with the metal surface, improving the coating's durability, wear resistance, and corrosion resistance. It also eliminates any internal stress that may exist in the coating or metal surface, reducing problems such as coating detachment and cracking during subsequent use. During the production process, the drilling tool needs to be transported to different workstations. Since the short-section drilling tool 2 is short in length but usually heavy, a specially designed lifting tool is required to ensure stability and safety during transportation.

[0028] like Figure 1 As shown, a suspended loading device for transporting short-section drilling tools is characterized in that it includes a suspended U-shaped guide rail 1, a short-section drilling tool 2, a hand-pull mobile trolley 3, a trolley body 31, a fall chain 32, trolley wheels 311, rollers 312 and a primer spraying plant roof 4.

[0029] Among them, such as Figure 2 As shown, the suspended U-shaped guide rail 1 is placed on the roof 4 of the primer spraying workshop, connecting the upper space of the spraying station and the furnace inlet station. Figure 3 and Figure 4 As shown, the short-section drill tool 2 is connected by a fall chain 32, suspended in the lifting hole below the trolley body 31 of the hand-pulled mobile trolley 3, and moved from the spraying station to the furnace entrance station through the suspended U-shaped guide rail 1; the trolley wheels 311 are installed on both sides of the trolley body 31 and embedded in the groove of the suspended U-shaped guide rail 1; the roller 312 is set at the bottom of the trolley body 31 and contacts the lower surface outside the groove of the suspended U-shaped guide rail 1, which is used to reduce the friction between the bottom of the trolley body 31 and the wing plate of the I-beam during sliding.

[0030] In this embodiment, the suspended U-shaped guide rail 1 is constructed by welding two I-beams with a curvature radius of 2 meters and a 90° bend angle. The I-beams are 16#a steel. To ensure longevity and production safety, the tensile strength of the I-beam welds is 480 to 660 MPa, and the yield strength of the welds is 270 to 280 MPa. To ensure smooth movement of the hand-pulled mobile trolley 3, the flatness tolerance of the I-beam welds is 0.2 mm. The flatness tolerance of the planes where the inner walls of the I-beam's wings and web contact the trolley wheels 311 and rollers 312 is 0.1 mm. The center of the suspended U-shaped guide rail 1 is located above the furnace entrance station, and the parallel portion is located above the spraying station. The ends of the parallel portion are equipped with baffles to limit the position of the hand-pulled mobile trolley 3. Both ends of the trolley body 31 and the baffles at the ends of the suspended U-shaped guide rail 1 are covered with anti-collision rubber to extend service life. The fall chain 32 has a lifting weight of 500 kg, a chain length of 3 m, and a lifting speed of 3 m / min. The length of the short drilling tool 2 is 1 m to 3 m, and the lower end of the fall chain 32 is fixed to the middle of the short drilling tool 2.

[0031] During the installation and application of the device of this embodiment, the short drill section 2 is placed at the workstation below the two parallel straight sections of the suspended U-shaped guide rail 1, i.e., the spraying workstation. After the primer is sprayed, the short drill section 2 at this workstation is lifted using the fall chain 32 at a lifting speed of 2 m / min. The lifted short drill section 2 is pushed along the suspended U-shaped guide rail 1, and the short drill section 2 drives the fall chain 32 to move. The fall chain 32 is suspended on a hook below the hand-pulled mobile car 3. The fall chain 32 drives the hand-pulled mobile car 3 to slide on the suspended U-shaped guide rail 1, causing the short drill section 2 to move to the middle of the suspended U-shaped guide rail 1, i.e., the middle of the two semi-circular I-beam guide rails. Below this position is the furnace mouth of the heating furnace. At this time, the fall chain 32 is used to lower the short drill section 2 to the furnace mouth, and the short drill section 2 can then enter the next workstation.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
