Description

Technical Field

[0001] This utility model belongs to the field of drilling rig technology, specifically relating to an efficient and precise rotary drilling rig positioning auxiliary construction device. Background Technology

[0002] With the continuous development of science and technology, the continuous improvement of infrastructure construction, and the continuous improvement of people's living standards, various engineering machinery is used in the process of infrastructure construction. Rotary drilling rigs play an important role in foundation construction. During the use of rotary drilling rigs, it is necessary to continuously remove the underground soil and drill again, repeating this cycle until the hole reaches the designed depth. However, during the drilling process, the drill bit of the rotary drilling rig is prone to deviation, causing the drilling position to deviate from the designed position, thus affecting the construction operation.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN213869713U discloses "an auxiliary device for rotary drilling rigs that is easy to position", which includes a base, a movable wheel, a telescopic rod, a moving rod, a worm gear, and a positioning barrel. The movable wheel is installed at the lower end of the base, and the telescopic rod is installed at the lower end of the base. A turntable is installed at the upper end of the support, and a worm gear is installed in the middle of the turntable. The moving rod is connected through the upper end of the support, and a clamp is provided on the inner side of the moving rod. A mounting seat is provided on the right side of the turntable, and a worm gear is installed between the mounting seats. The positioning barrel is clamped between the clamps, and a guide ring is provided above the positioning barrel.

[0004] Although existing rotary drilling rig positioning auxiliary construction devices can be easily moved to the required position using moving wheels and supported by telescopic rods to prevent displacement during operation and improve positioning accuracy, some problems exist in practical applications. Due to the lack of a convenient storage component on the telescopic rod, users can only adjust the height of the control pads for support and positioning via the telescopic rod. When moving on uneven ground, the length of the telescopic rod means that when the moving wheels cross raised clods of earth, clods of soil or other stones can easily impact the telescopic rod and control pads, potentially causing damage.

[0005] To address the aforementioned issues, this application proposes an efficient and precise rotary drilling rig positioning auxiliary construction device. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-4 The present invention provides the following technical solution: an efficient and precise rotary drilling rig positioning machine auxiliary construction device, including a trolley 1, a positioning bucket 2 fixed on the top of the trolley 1, and several wheels 3 on the bottom of the trolley 1. Electric push rods 4 for auxiliary support of the trolley 1 are also installed at the bottom of the trolley 1 near the position of the wheels 3. A support block 5 is fixed at the output end of the electric push rod 4.

[0026] The flatbed trolley 1 is also equipped with four sets of adjustment components for driving the four electric push rods 4 to rotate. In use, the flatbed trolley 1 is first moved by the wheels 3, and then the flatbed trolley 1 is positioned in a suitable position according to the construction needs, so as to ensure that the positioning bucket 2 can be accurately positioned at the drilling position of the rotary drilling rig. In addition, the auxiliary support function of the electric push rods 4 can effectively prevent the flatbed trolley 1 from shifting due to drilling vibration during rotary drilling, thereby ensuring the accuracy of construction.

[0027] Specifically, by Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the adjustment component includes a mounting bracket 6 fixed on the fixed plate 1, a connecting pipe 16 fixed at one end of the electric push rod 4, a second clearance hole 18 opened on the connecting pipe 16, a U-shaped connecting block 14 fixed on the connecting pipe 16, an internal thread hole 15 opened on the U-shaped connecting block 14, and a bolt 17 installed on the U-shaped connecting block 14 through the internal thread hole 15.

[0028] The mounting bracket 6 has an arc-shaped guide hole 7 for the bolt 17 to slide. At both ends of the arc-shaped guide hole 7 are a storage hole 8 and a support hole 9 for use with the bolt 17.

[0029] The mounting bracket 6 is also equipped with a rotating shaft, and a connector 10 is connected to the mounting bracket 6 via the rotating shaft. The connector 10 has a first clearance hole 11 for the mounting bracket 6 to be inserted into. The connector 10 also has a guide hole 12 for cooperating with the bolt 17. A spring 13 for driving the U-shaped connecting block 14 to reset is also fixed on the connector 10. In use, firstly, the connector 10 is installed on the mounting bracket 6 via the rotating shaft, while ensuring that one side of the mounting bracket 6 is inserted into the inner wall of the first clearance hole 11. Then, the connector 10 is rotated by the rotating shaft to align the guide hole 12 with the arc-shaped guide hole 7 and the receiving hole 8. Next, the connecting tube 16 and the U-shaped connecting block 14 are sleeved on the connector 10, ensuring that one end of the spring 13 is tightly fitted with the inner wall of the U-shaped connecting block 14. Then, one end of the bolt 17 is installed on the internal thread hole 15 and passes through the receiving hole 8 and the guide hole 12 to complete the initial fixing of the adjustment component.

[0030] When it is necessary to fix the trolley 1, the user can manually push the connecting pipe 16 to move the U-shaped connecting block 14 towards the connector 10, causing the U-shaped connecting block 14 to compress the spring 13 and retract it. At this time, the U-shaped connecting block 14 will drive the bolt 17 to move, causing the bolt 17 to disengage from the receiving hole 8 and slide into the arc-shaped guide hole 7. The user can then use the bolt 17 to slide along the arc-shaped guide hole 7 until the bolt 17 contacts the support hole 9. At this time, the spring 13 will push the U-shaped connecting block 14 to reset, and the bolt 17 will move into the support hole 9 for fixing. At this time, one end of the connecting pipe 16 will be tightly fitted to the bottom of the trolley 1. The user can then activate the electric push rod 4 to make the support block 5 contact the ground, thereby achieving stable support for the trolley 1. By adjusting the extension length of the electric push rod 4, the height of the support block 5 can be precisely controlled to ensure that the positioning barrel 2 is accurately positioned in the required position.

[0031] When it is necessary to store the electric actuator 4 and the support block 5, the user only needs to push the U-shaped connecting block 14 towards the connector 10 again, so that the bolt 17 disengages from the support hole 9 and slides into the storage hole 8, thus completing the storage of the electric actuator 4. In addition, due to the structural design of the adjustment component, the device can effectively avoid damage to the electric actuator 4 and the support block 5 when moving on uneven ground, thereby improving the durability and reliability of the device.

[0032] Specifically, by Figure 3 and Figure 4 As shown, in this embodiment, the length of the guide hole 12 is greater than the diameter of the internal thread hole 15; so that the bolt 17 on the U-shaped connecting block 14 can slide freely in the guide hole 12, thereby achieving a quick fixation of the operating angle of the electric push rod 4.

[0033] Specifically, by Figure 4 As shown, in this embodiment, the connector 10, the U-shaped connecting block 14, and the connecting pipe 16 are all made of metal; this ensures the strength and durability of the device. The use of metal not only improves the load-bearing capacity of the device, but also maintains good performance in harsh working environments, such as high temperature, high humidity, or environments containing corrosive substances.

[0034] Specifically, by Figure 4 As shown, in this embodiment, the length of the bolt 17 is greater than the width of the U-shaped connecting block 14, so that the bolt 17 can pass through the entire adjustment assembly, thereby providing sufficient space for adjustment and fixation.

[0035] Components not described in detail in this article are existing technologies.

[0036] The working principle and usage process of this utility model are as follows: During use, firstly, the connector 10 is installed on the mounting bracket 6 via a rotating shaft, while ensuring that one side of the mounting bracket 6 is inserted into the inner wall of the first clearance hole 11. Then, the connector 10 is rotated via the rotating shaft to align the guide hole 12 with the arc-shaped guide hole 7 and the receiving hole 8. Next, the connecting tube 16 and the U-shaped connecting block 14 are fitted onto the connector 10, ensuring that one end of the spring 13 is tightly fitted with the inner wall of the U-shaped connecting block 14. Then, one end of the bolt 17 is installed on the internal threaded hole 15 and passes through the receiving hole 8 and the guide hole 12 to complete the initial fixing of the adjustment component.

[0037] When it is necessary to fix the trolley 1, the user can manually push the connecting pipe 16 to move the U-shaped connecting block 14 towards the connector 10, causing the U-shaped connecting block 14 to compress the spring 13 and retract it. At this time, the U-shaped connecting block 14 will drive the bolt 17 to move, causing the bolt 17 to disengage from the receiving hole 8 and slide into the arc-shaped guide hole 7. The user can then use the bolt 17 to slide along the arc-shaped guide hole 7 until the bolt 17 contacts the support hole 9. At this time, the spring 13 will push the U-shaped connecting block 14 to reset, and the bolt 17 will move into the support hole 9 for fixing. At this time, one end of the connecting pipe 16 will be tightly fitted to the bottom of the trolley 1. The user can then activate the electric push rod 4 to make the support block 5 contact the ground, thereby achieving stable support for the trolley 1. By adjusting the extension length of the electric push rod 4, the height of the support block 5 can be precisely controlled to ensure that the positioning barrel 2 is accurately positioned in the required position.

[0038] When it is necessary to store the electric actuator 4 and the support block 5, the user only needs to push the U-shaped connecting block 14 towards the connector 10 again, so that the bolt 17 disengages from the support hole 9 and slides into the storage hole 8, thus completing the storage of the electric actuator 4. In addition, due to the structural design of the adjustment component, the device can effectively avoid damage to the electric actuator 4 and the support block 5 when moving on uneven ground, thereby improving the durability and reliability of the device.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
