Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] It should be noted that when a component is referred to as being "set on" or "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is referred to as being "fixed to" another component, or "fixedly connected" to another component, the fixing method can be detachable or non-detachable. When a component is considered to be "connected" or "rotatably connected" to another component, it can be directly connected to the other component or there may be an intermediate component. The terms "vertical," "horizontal," "left," "right," "upper," "lower," and similar expressions used are for illustrative purposes only and do not represent the only possible implementation.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] In this utility model, terms such as "first," "second," and "third" are used not to represent specific quantities or orders, but merely to distinguish names.

[0035] In some embodiments, refer to Figure 1 As shown, the present invention provides a welding device for a drill rod and a drill bit, comprising:

[0036] Feeding area 1, which is used to stack drill rods;

[0037] A feeding mechanism, comprising: a support component and a conveying component, wherein the support component is used to support the drill pipe;

[0038] The discharge mechanism includes a lifting component and a finished product area 2. The lifting component is used to lift the welded drill rod into the finished product area 2.

[0039] A welding mechanism, comprising: a traction component 3 and a welding component 14, wherein the conveying component is used to move the drill rod on the supporting component closer to or away from the traction component 3, the traction component 3 is used to pull the drill rod so that the drill rod moves closer to or away from the welding component 14, and the welding component 14 is used to weld the drill rod and the drill bit.

[0040] After the drill rod in the feeding area 1 rolls onto the support component, the conveying component transports the drill rod on the support component to the traction component 3. Then, the traction component 3 pulls the drill rod until it comes into contact with the drill bit. The welding component 14 then welds the drill rod and the drill bit together. After welding, the traction component 3 pulls the drill rod back until it reaches the end of its stroke. This triggers the lifting component to lift the drill rod until it rolls into the finished product area 2. The lifting component then resets, and the conveying component resets the support component. At this point, the drill rod in the feeding area 1 rolls onto the support component again, and a new round of operation begins.

[0041] In some embodiments, refer to Figure 1 As shown, the supporting component includes a hollow supporting platform 4, which is connected to the conveying component.

[0042] The lifting assembly, through the central gap of the support platform 4, makes it easier to lift the drill rod, further improving the overall smoothness of the welding equipment's operation.

[0043] In some embodiments, refer to Figure 1 As shown, the support platform 4 is provided with at least two rollers 5 for receiving drill rods.

[0044] The rollers 5 installed on the support platform 4 can improve the smoothness and stability of the drill rod when it is pulled by the traction component 3, and prevent it from shaking during the traction process.

[0045] In some embodiments, refer to Figure 1 As shown, the conveying assembly includes a first cylinder 6 and a first swing arm 7. The output end of the first cylinder 6 is connected to the first swing arm 7, and the first swing arm 7 is connected to the supporting assembly.

[0046] When the first cylinder 6 pushes the first swing arm 7, the drill rod on the support assembly moves away from the traction assembly 3;

[0047] When the first cylinder 6 pulls the first swing arm 7, the drill rod on the support assembly moves closer to the traction assembly 3.

[0048] After the drill rod falls onto the support assembly, the first cylinder 6 pulls the first swing arm 7, causing the drill rod on the support assembly to move closer to the traction assembly 3, so that the traction assembly 3 can fit the drill rod with the drill bit. After welding is completed, the traction assembly 3 pulls the drill rod out until the drill rod reaches the end of its stroke, triggering the lifting assembly to lift the drill rod until it rolls into the finished product area 2. The lifting assembly then resets, and then the conveying assembly resets the support assembly. At this time, the drill rod in the loading area 1 rolls back onto the support assembly, and a new round of operation begins.

[0049] In some embodiments, refer to Figure 1 As shown, the lifting assembly includes a second cylinder 8, a second swing arm 9, and a transmission component 10. The output end of the second cylinder 8 is connected to the second swing arm 9, and the transmission component 10 is connected to the second swing arm 9.

[0050] When the second cylinder 8 pushes the second swing arm 9, the transmission component 10 moves closer to the support assembly until the drill rod is lifted;

[0051] When the second cylinder 8 pulls the second swing arm 9, the transmission component 10 moves away from the support assembly.

[0052] After the drill rod is welded, the second cylinder 8 pushes the second swing arm 9, causing the transmission component 10 to approach the drill rod until the drill rod is lifted and falls into the finished product area 2. Then the second cylinder 8 pulls the second swing arm 9, causing the transmission component 10 to reset so that the next drill rod can fall into the support assembly.

[0053] In some embodiments, refer to Figure 1As shown, the lifting assembly also includes a connecting rod 11, and multiple transmission components 10 are provided, which are connected to each other through the connecting rod 11.

[0054] By connecting multiple transmission components 10 with a connecting rod 11, multiple transmission components 10 can simultaneously lift the drill pipe, thereby improving the stability of the drill pipe when it is lifted.

[0055] In one embodiment, limiting groove structures can be provided on both sides of the connecting rod 11 to maintain the stability of the transmission member 10 during the lifting and lowering process.

[0056] In some embodiments, refer to Figure 1 As shown, the supporting component includes a first limiting member 12;

[0057] When the drill rod on the supporting component abuts against the traction component 3, the first limiting member 12 abuts against the drill rod in the feeding area 1 to prevent the drill rod from falling.

[0058] When the drill rod on the supporting assembly moves away from the traction assembly 3, the first limiting member 12 separates from the drill rod in the feeding area 1.

[0059] After the welded drill rod is transported to the finished product area 2 by the lifting component, the lifting component resets. At this time, the conveying component raises and resets the supporting component. The first limiting member 12 is higher than the drill rod in the loading area 1, and the drill rod slides into the supporting component. When the conveying component pulls down the supporting component so that the drill rod abuts against the traction component 3, the first limiting member 12 limits the drill rod in the loading area 1 to prevent it from falling into the supporting component, thus realizing single-piece loading.

[0060] In some embodiments, refer to Figure 1 As shown, the supporting component includes a second limiting member 13, and the top of the second limiting member 13 is provided with a sloping surface;

[0061] When the lifting assembly raises the welded drill rod above the second limiting member 13, the drill rod slides into the finished product area 2 along the slope.

[0062] When the welded drill rod is lifted by the lifting assembly until it is higher than the second limiting member 13, the drill rod slides into the finished product area 2 along the slope. Then, when a new drill rod falls into the supporting assembly, the second limiting member 13 can limit the fall of the drill rod to prevent it from rolling excessively into the finished product area 2.

[0063] In some embodiments, the traction component 3 may be any device such as a traction machine that can axially pull or push the drill pipe.

[0064] In some embodiments, the welding assembly 14 includes a welding torch, a first drive source, and a drive wheel assembly, wherein the first drive source drives the drive wheel assembly to rotate, thereby causing the drill pipe to rotate.

[0065] The first drive source drives the drive wheel assembly to rotate, enabling the welding torch to weld the entire drill rod, further improving the efficiency of automated production.

[0066] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
