Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The core of this utility model is to provide an adjustable drilling joint balancing hoisting device, which is a tooling equipment that can effectively solve the problem of drilling joint hoisting, and has the advantages of simple operation, high efficiency, safety, stability and reliability. Another core aspect of this utility model is to provide a drilling joint conveying device including the above-mentioned adjustable drilling joint balancing hoisting device.

[0031] Please refer to Figure 1 and Figure 2 This specific embodiment provides an adjustable drilling joint balancing hoisting device, including:

[0032] The hoisting body 1 includes a horizontally placed first arm, a vertically placed second arm on one side of the first arm, and an inclined third arm on the top of the second arm. The angle between the third arm and the second arm is an obtuse angle. The end of the first arm is provided with an assembly part for detachably installing the drilling joint 4. The end of the third arm is provided with a connecting pin hole 12 and a balance pin hole 13 spaced apart from the connecting pin hole 12.

[0033] U-shaped lifting lug 2 is used in conjunction with lifting equipment;

[0034] The balance adjustment device 3 includes a handle portion with a first mounting hole and a blade portion connected to the handle portion. The first mounting hole is used to install a U-shaped lug 2. The blade portion is provided with a second mounting hole aligned with the connecting pin hole 12 and a plurality of spaced adjustment holes 31. The second mounting hole is used to install a connecting shaft pin 121. When the blade portion rotates, the different adjustment holes 31 align with the balance pin hole 13 to install the balance shaft pin 131.

[0035] In practical applications, the shape, structure, size, material, and position of the hoisting body 1, U-shaped lifting lugs 2, and balance adjustment device 3 can be determined according to the actual situation and needs.

[0036] When using the adjustable drilling joint balancing hoisting device provided by this utility model, firstly, the connecting shaft pin 121 is passed through the second mounting hole and the connecting pin hole 12 and locked to connect the balancing adjustment device 3 to the third arm of the main body 1. Then, the drilling joint 4 is detachably installed on the assembly part. Afterwards, the operator can insert the balancing shaft pin 131 into the corresponding adjusting hole 31 according to the weight of the drilling joint being hoisted, thereby achieving balanced hoisting of drilling joints of different volumes and weights. That is, by setting multiple spaced adjusting holes 31, aligning different adjusting holes 31 and balancing pin holes 13 and installing balancing shaft pins 131, the distance between the U-shaped lifting lug 2 connected to the hoisting device and the balancing shaft pin 131 can be changed to meet the hoisting needs of drilling joints of various specifications, volumes, and weights. Finally, the U-shaped lifting lug 2 is inserted into the lifting lug hole of the hoisting device, and then the balanced hoisting operation of different drilling joints can be achieved by using a wire rope or a special sling.

[0037] In summary, the adjustable drilling joint balancing hoisting device provided by this utility model is a tooling equipment that can effectively solve the hoisting problem of drilling joint 4, and has the advantages of simple operation, high efficiency, safety, stability and reliability.

[0038] In one embodiment, the first arm, the second arm, and the third arm are an integral structure to improve the structural stability of the hoisting body 1 and reduce the assembly operations of the hoisting body 1.

[0039] In one embodiment, reinforcing ribs 11 are provided on opposite sides of the second arm.

[0040] It should be noted that during the hoisting of the drilling joint 4 using the adjustable drilling joint balancing hoisting device, the second arm is the main stress-bearing part of the hoisting body 1. By providing reinforcing ribs 11 on the opposite sides (e.g., the front and rear sides) of the second arm, it can be effectively prevented from being deformed due to excessive force.

[0041] In one embodiment, the cutting edge includes a semi-circular arc structure with a radius of 100 mm. The semi-circular arc structure has at least two equal-diameter adjustment holes 31 spaced along its circumference. For example, six adjustment holes 31 can be equally spaced on the semi-circular arc structure. When the balance pin 131 is inserted into different adjustment holes 31 and balance pin holes 13, the lever arm between the U-shaped lifting lug 2 and the balance pin 131 changes, thereby enabling the device to meet the lifting needs of drilling joints 4 of various specifications, volumes, and weights. By using this device, the lifting problem of drilling joints 4 can be effectively solved. Furthermore, this device has advantages such as simple operation, high efficiency, high safety, and strong stability. Moreover, the unique balance adjustment device 3 of this device can meet the lifting needs of drilling joints 4 of various specifications, volumes, and weights.

[0042] In one embodiment, the handle and the blade are an integral structure to improve the structural stability of the balance adjustment device 3.

[0043] In one embodiment, the connecting pin 121 is provided with an anti-detachment structure. For example, a thread can be provided at the root of the connecting pin 121, and an internal thread can be provided in the connecting pin hole 12. After the connecting pin 121 is screwed into the connecting pin hole 12, the protruding top of the connecting pin 121 is embedded in the second mounting hole to prevent the connecting pin 121 from falling off during use.

[0044] In one embodiment, such as Figure 3 As shown, it can be located at the root of the balance pin 131 (e.g. Figure 3 The threaded portion of the balance pin 13 has threads, and the balance pin hole 13 has internal threads. After the balance pin 131 is screwed into the balance pin hole 13, the top of the balance pin 131 protrudes (as shown in the image). Figure 3 The part marked with a line is embedded in the corresponding adjustment hole 31. This setting ensures that the balance shaft pin 131 will not fall off during the hoisting process after it is assembled in place.

[0045] In one embodiment, such as Figure 2 As shown, the upper and lower parts of one side of the second arm are respectively provided with handles 15 for hand holding, so that the operator can manually support the hoisting body 1 to control the direction and trajectory of the hoisting body 1.

[0046] In one embodiment, the end of the assembly part is provided with two oppositely distributed bearing pin holes 14, a bearing 141 sandwiched within the two bearing pin holes 14, and a bearing pin 142. The bearing pin 142 is disposed through the bearing pin holes 14 and the bearing 141. The bearing 141 is used for rolling friction with the inner wall of the drilling joint 4. The outer periphery of the bearing 141 contacts the inner wall of the drilling joint 4, changing the radial friction between the drilling joint 4 and the assembly part into rolling friction between the drilling joint 4 and the bearing 141, which facilitates the assembly and removal of the drilling joint 4.

[0047] To further illustrate the usage of the adjustable drilling joint balancing hoisting device provided by this utility model, the following examples will be provided.

[0048] First, the balance adjustment device 3 is connected to the hoisting body 1 via the connecting pin 121. Since the connecting pin 121 is designed to prevent detachment, it can effectively ensure that the nut on one side of the connecting pin 121 will not loosen due to the rotation of the connecting pin 121 while the balance adjustment device 3 is rotating.

[0049] Then, the bearing 141 is inserted into the bearing pin hole 14 of the hoisting body 1 through the bearing pin 142. The bearing 141 protrudes slightly from the plane of the hoisting body 1 and the drilling joint 4 so that the assembly part can easily enter and exit the inner hole of the hoisted drilling joint 4 when using this device.

[0050] Subsequently, the balance adjustment device 3 is designed with six adjustment holes 31 of the same diameter evenly distributed on a semi-circular arc with a pitch circle radius of 100mm. Depending on the weight of the drill joint 4 being lifted, the balance pin 131 can be inserted into the corresponding adjustment hole 31, thereby achieving balanced lifting of drill joints 4 of different volumes and weights. To effectively ensure its strength and prevent it from easily detaching during use, the balance pin 131 employs a special design, as shown in the attached diagram. Figure 3 As shown, the base of the balance pin 131 is designed with threads, and the balance pin hole 13 that matches it is provided with internal threads. After the balance pin 131 is screwed into the balance pin hole 13, the top of the balance pin 131 that is exposed is just embedded in the corresponding adjustment hole 31 to achieve balanced lifting of the drilling joint 4.

[0051] Finally, insert the U-shaped lifting lug 2 into the lifting lug hole of the hoisting device, and then use wire rope or special slings to achieve balanced lifting of different drilling joints 4.

[0052] This device employs an adjustable torque balance adjustment device 3, which can meet the balanced lifting operation of drilling joints 4 of different sizes and weights during operation, facilitating operation and achieving multiple uses in one device, making it more practical than other patents. Furthermore, the connecting pins 121 adopt a unique anti-detachment structure, ensuring that even with repeated rotation, the connecting pins 121 will not fall off, guaranteeing safety. Additionally, the device features reinforcing ribs 11 (e.g., reinforcing plates) on opposite sides of the second arm, significantly enhancing its strength, increasing lifting power, and ensuring safety. Furthermore, bearings 141 are installed at the contact point between the assembly and the drilling joint 4, further facilitating operation. This device has been extensively applied in practice, with prototypes manufactured, demonstrating significant lifting performance. It is suitable for lifting drilling joints 4 during thread repair, handling, and loading, thereby improving the safety, stability, and efficiency of drilling joint 4 lifting operations.

[0053] In addition to the aforementioned adjustable drilling joint balancing hoisting device, this utility model also provides a drilling joint conveying device that includes the adjustable drilling joint balancing hoisting device disclosed in the above embodiments. This drilling joint conveying device further includes a drilling joint 4, and the assembly part of the adjustable drilling joint balancing hoisting device is detachably connected to the drilling joint 4. The structure of the other parts of this drilling joint conveying device is described in the prior art and will not be repeated here.

[0054] It should be noted that the first arm, second arm, third arm, first mounting hole, and second mounting hole mentioned in this application are only distinguished by their different positions and do not indicate any order of priority.

[0055] In addition, it should be noted that the orientation or positional relationship indicated by "up and down" or "inside and outside" in this application is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the purpose of simplifying the description and making it easier to understand, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
