Description

Technical Field

[0001] This application relates to the technical field of geotechnical exploration equipment, and particularly to a drilling rig for soil exploration. Background Art

[0002] With the continuous development of urban construction and infrastructure construction, the demand for geotechnical exploration is increasing day by day. Although there are various existing exploration tools, there are still many limitations and challenges when dealing with different geological conditions; especially in strata with uneven hardness, traditional exploration tools often have difficulty maintaining a stable working state, resulting in problems such as low exploration efficiency and poor data accuracy. In addition, due to design limitations, the maintenance and repair of many exploration equipment are also relatively difficult, increasing the use cost; Specific solutions of the existing technology: To overcome the above problems, two mainstream technical means are usually adopted in the industry. The first is to improve the stability by enhancing the rigidity of mechanical equipment. This method is common in heavy drilling equipment. Although it can effectively improve the working performance of the equipment in harsh environments, due to its large weight, it is inconvenient to move and has high energy consumption. The second is to adopt a modular design. By reducing the volume and mass of individual components, the equipment is made more flexible and portable, suitable for rapid deployment. However, this design is prone to rapid wear and short life when facing high-intensity operations. These two solutions have their own advantages, but also have obvious deficiencies.

[0003] Although the design solution of enhancing rigidity in the existing drilling rig for soil exploration improves the durability of the equipment during use, it sacrifices mobility and economy; while the modular design improves flexibility, but performs poorly under long-term continuous operation, is prone to damage, and requires frequent maintenance. These all limit the actual application scope and effect of the existing geotechnical exploration equipment. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, this application provides a drilling rig for soil exploration, which overcomes the deficiencies of the existing technology and aims to solve the problems in the existing technology that although the design solution of enhancing rigidity in the existing drilling rig for soil exploration improves the durability of the equipment during use, it sacrifices mobility and economy; while the modular design improves flexibility, but performs poorly under long-term continuous operation, is prone to damage, and requires frequent maintenance. These all limit the actual application scope and effect of the existing geotechnical exploration equipment.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a drilling rig for soil exploration, comprising a main frame, a placement cavity is provided inside the main frame, a placement frame is installed inside the placement cavity, a connecting frame is provided inside the placement frame, a drilling mechanism is installed inside the connecting frame, the drilling mechanism comprises a driving motor, a mounting ring and a telescopic rod, a rotating groove is provided at the bottom of the driving motor, a telescopic rod is provided at the bottom of the mounting ring, a drill bit is installed at the output end of the telescopic rod, support mechanisms are provided at the four corners of the bottom of the main frame, four groups of support mechanisms each comprise a support leg and a hydraulic rod, one end of the hydraulic rod is fixedly connected to the main frame, a support leg is fixedly installed at the bottom of the hydraulic rod, a mounting groove is provided on one side of the main frame, a control panel is provided inside the mounting groove, and a display screen and buttons are provided on the outside of the control panel.

[0006] By adopting the above technical solution and setting up a main frame, when in use, the operator sets the drilling depth and other necessary parameters through the control panel, and then the drilling rig is started, and the drive motor can drive the drill bit to rotate rapidly and gradually go deeper into the ground. During this process, the four sets of hydraulic rods can automatically adjust the height of the support mechanism according to the undulation of the ground, and can effectively maintain the balance of the machine body according to the height and undulation of the ground. After completing the predetermined depth, the drive motor is driven to rotate the drill bit in the opposite direction to remove it, and the acquired data is recorded. This setting is exquisitely designed and compact in structure. It is not only easy to transport and carry, but also can successfully complete drilling tasks under various terrain conditions. Through reasonable layout and selected materials, the frequency of daily maintenance is greatly reduced, and the difficulty of operation for users is reduced, thereby improving overall work efficiency and safety.

The other ends of the two groups of rotating rods pass through the main frame and the placement rack, and the placement rack is threadedly connected to the two groups of rotating rods.

A stabilizing rod 2 is provided on the top of the fixed block, and the other end of the stabilizing rod 2 passes through the mounting block, and the stabilizing rod 2 is slidably connected to the inside of the mounting block.

[0010] By adopting the above technical solution, by setting the fixed block, during use, the four groups of the support mechanisms can be made more stable during the up-and-down movement, which can further improve the stability of the overall device placement and enhance the practicability of the device.

[0012] By adopting the above technical solution, by setting the driving motor as a three-phase asynchronous motor with a rated power of 5KW, sufficient power output is ensured; the material of the drill bit is selected as 42CrMo alloy steel, which has high hardness and strong corrosion resistance, and the service life is prolonged; the hydraulic rod is selected as a product with a rated pressure of 16MPa to provide sufficient lifting force support.

[0013] As a preferred technical solution of the present application, a fixing ring is installed outside the drill bit, and four groups of stabilizing rods I are installed inside the fixing ring. The four groups of the stabilizing rods I all penetrate through the installation ring, and the four groups of the stabilizing rods I are all slidably connected with the installation ring.

[0014] By adopting the above technical solution, by setting the fixing ring, during use, the drill bit can be made more stable during the up-and-down movement, and it is also more stable during the rotation process, improving the stability of the device during use.

[0015] As a preferred technical solution of the present application, universal wheels are provided at the bottoms of the four groups of the support legs.

[0016] By adopting the above technical solution, by setting the universal wheels, during use, the position of the main frame can be moved more conveniently, and it is more labor-saving when moving the main frame, enhancing the practicability of the device.

[0017] As a preferred technical solution of the present application, four groups of connecting frames are provided at the top of the placement rack, and the other ends of the connecting frames are fixedly connected with the driving motor.

[0018] By adopting the above technical solution, by setting the connecting frames, during use, the fixed connection between the placement rack and the drilling mechanism can be further realized, and it is convenient for subsequent installation, maintenance and replacement, enhancing the practicability of the device.

[0019] As a preferred technical solution of the present application, the size of the rotating groove matches that of the installation ring.

[0020] By adopting the above technical solution, since the size of the rotation groove matches the installation ring, it can be more stable during rotation, enhancing the stability of the device operation.
