Description

Technical Field

[0001] This utility model relates to the field of civil engineering equipment technology, specifically to a drilling rig stabilization device and a drilling rig. Background Technology

[0002] Drilling rigs are widely used in drilling operations in mining, tunneling, and construction projects. During drilling, the rig needs to maintain good contact and fixation with the working face. However, existing drilling rigs suffer from the following problems: the lack of an effective stabilizing structure between the rig and the working face prevents the rig from maintaining proper contact and fixation during drilling. This is especially problematic in high-precision operations such as anchor bolt drilling, where the drill frame is prone to shaking or shifting, leading to borehole position deviations, drilling failures, or damage to drilling tools, severely impacting construction efficiency and quality.

[0003] Therefore, there is an urgent need to develop a drilling rig stabilization device that is simple in structure, easy to install, and highly stable to overcome the shortcomings of existing technologies. In view of this, this utility model patent is hereby proposed. Utility Model Content

[0031] See Figures 1-2 As shown, a drilling stabilization device for a drilling rig in this embodiment includes:

[0032] A perforated surface contact assembly includes a contact body 103, the contact body 103 having a first end that abuts against the perforated surface and a second end opposite to the first end;

[0033] The connecting seat 101 is fixedly connected to the second end of the contact body 103, and the connecting seat 101 is used to fixally connect to the drill bit position of the drilling rig.

[0034] The contact body 103 and the connecting seat 101 have interconnected drill bit channels, and the drill rod installed on the drill bit passes through the drill bit channels to drill into the drilling surface.

[0035] The drilling stabilization device for drilling rigs provided in this embodiment can achieve the following beneficial effects through the above technical solution:

[0036] Significantly improves drilling stability and accuracy: By directly and firmly contacting the drilling surface with the working face, the drilling rig and the working face form a stable integral structure, effectively absorbing and offsetting the vibration and reaction force generated during drilling, preventing the drilling rig from jumping and deviating, thereby ensuring the straightness and positional accuracy of the borehole and greatly reducing the drilling failure rate.

[0037] Easy to install and highly versatile: The device connects to the drill bit of the drilling rig via a standardized connection body (such as an annular body with bolt holes), making installation and disassembly simple and quick, without requiring complex modifications to existing drilling rigs. This device is adaptable to various models of drilling rigs, offering high interchangeability and facilitating widespread use. As an optional implementation in this embodiment, the connection body 101 is an annular body, with a hollow interior forming the drill bit channel for the drill rod mounted on the drill bit to pass through.

[0038] Furthermore, a plurality of connecting bolt holes 102 are evenly provided on the annular seat 101 along the circumference. The connecting bolts pass through the connecting bolt holes 102 and are fastened to the drill head position of the drill rig for fixed connection.

[0039] As an optional implementation of this embodiment, the contact body 103 in this embodiment includes a first contact wall 104 and a second contact wall 105. The second ends of the first contact wall 104 and the second contact wall 105 are respectively fixedly connected to the connecting seat 101, and the first contact wall 104 and the second contact wall 105 are arranged opposite to each other on the connecting seat 101.

[0040] In this embodiment, by setting up opposing first contact walls 104 and second contact walls 105, effective support can be provided on both sides of the drill rod during the drilling process, ensuring stable and reliable drilling.

[0041] Furthermore, in this embodiment, the first ends of both the first contact wall 104 and the second contact wall 105 are curved surfaces. This allows for better adaptation to various perforated surfaces and ensures close contact with the perforated surface.

[0042] Furthermore, in this embodiment, the first ends of the first contact wall 104 and the second contact wall 105 are each provided with a plurality of toothed grooves 108 to form toothed contact ends.

[0043] Through the above structural design, the drilling stabilization device of this embodiment enhances the adhesion to the working surface: by setting tooth-shaped structures (such as fan-shaped tooth-shaped contact points) at the first end (i.e. the end in contact with the working surface) of the first contact wall 104 and the second contact wall 105, the contact friction and biting force with the uneven or loose working surface are effectively increased, preventing the device from slipping during drilling and further ensuring stable construction operations.

[0044] As an optional implementation of this embodiment, the contact body 103 includes a third contact wall 106 and a fourth contact wall 107. The second ends of the third contact wall 106 and the fourth contact wall 107 are respectively fixedly connected to the connecting seat 101. The side walls of the first contact wall 104, the third contact wall 106, the second contact wall 105, and the fourth contact wall 107 are connected in sequence to form an annular body. The interior of the annular body is hollow, forming the drill bit channel. In this way, the overall strength of the contact body 103 can be further enhanced, ensuring the support stability of the drilling rig during the drilling process.

[0045] As an optional implementation of this embodiment, the perforated surface contact assembly of this embodiment includes a reinforcing plate 109, and the two ends of the reinforcing plate 109 are fixedly connected to the first contact wall 104 and the second contact wall 105, respectively.

[0046] In this way, the two ends of the reinforcing plate 109 are fixedly connected to the first contact wall 104 and the second contact wall 105, respectively, forming a stable I-shaped or similar frame structure. This structure not only has good mechanical properties and strong load-bearing capacity, but also has a simple manufacturing process, mainly using mature processes such as laser cutting and bending, resulting in low manufacturing costs and suitability for mass production.

[0047] Furthermore, in this embodiment, the reinforcing plate 109 is fixedly connected to the centerline positions of the first contact wall 104 and the second contact wall 105 respectively, and the reinforcing plate 109 divides the drill bit channel of the contact body 103 into two sub-channels.

[0048] like Figure 3 As shown, this embodiment also provides a drilling rig 200 with the drilling rig stabilization device, including a drill bit. The connecting base 101 of the drilling rig stabilization device 100 is fixedly connected to the drill bit. The drill rod installed on the drill bit passes through the drill bit channel of the drilling rig stabilization device 100 and drills into the drilling surface.

[0049] In this embodiment, the drilling rig 200 is a drilling stabilizing device 100 installed at the front of the drilling frame. It is connected to the drilling frame by bolts. During the operation of the drilling rig, the drilling stabilizing device 100 contacts the drilling surface to be drilled, and the drill arm applies a certain force to the drilling frame, thereby fixing the drilling frame firmly on the drilling surface and finally drilling the hole.

[0050] In this embodiment, the drilling rig 200 is installed on the drilling engineering vehicle 300 for on-site construction.

[0051] The drilling rig 200 provided in this embodiment, by integrating the aforementioned drilling rig stabilization device 100, achieves a significant improvement in overall machine performance. The specific technical effects are as follows:

[0052] Significantly improves the stability and drilling accuracy of the entire machine: The drilling stabilization device 100, acting as a rigid connecting bridge between the drill frame and the working face, effectively transmits and disperses the vibrations and impacts generated by the drill 200 during operation to the working face. This fundamentally suppresses the front-end swaying and overall chatter of the drill frame, enabling the drill rod to drill stably along a predetermined trajectory, greatly improving the straightness, positional accuracy, and forming quality of the borehole. It is particularly suitable for scenarios such as anchor bolt support where high drilling accuracy is required.

[0053] Optimized power transmission efficiency and protection of critical components: Due to the more stable drill frame system, harmful loads such as eccentric loads and bending moments experienced by the drill bit and drill rod during drilling are significantly reduced. This allows the drill rig's output power to be more concentrated on rock breaking, improving drilling efficiency. Simultaneously, reduced abnormal vibrations impacting the drill rig's internal transmission system, hydraulic system, and drill bit contribute to extending the service life of the entire machine and critical components, and lowering maintenance costs.

[0054] Enhancing the drilling rig's adaptability to complex working conditions: The toothed contact structure at the front end of the drilling stabilization device 100 can effectively engage uneven, loose, or inclined working surfaces, providing a reliable temporary "anchoring" point for the drilling rig 200. This allows the drilling rig 200 to maintain a stable drilling posture even in harsh geological conditions or confined working spaces, expanding the application range of the drilling rig.

[0055] High structural integration and convenient operation: The drilling stabilization device 100 is fixed to the drill bit via a standardized connecting base, making installation and disassembly simple and quick without requiring complex modifications to the main body of the drilling rig 200. As an inherent functional module of the drilling rig 200, this device does not damage the original structure and mobility of the drilling rig 200, achieving a "ready-to-use, stable and efficient" operation mode and improving the convenience of construction organization.

[0056] In summary, this drilling rig 200, through the integration of the drilling rig stabilization device 100, solves the inherent stability problem of traditional drilling rigs during drilling, achieving comprehensive optimization in accuracy, efficiency, reliability, and applicability, and exhibiting superior overall performance.

[0057] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
