Description

Technical Field

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

[0002] A drilling device refers to a mechanical device and equipment for specific working conditions in drilling construction.

[0003] A prior patent (publication number: CN 217206291U) discloses a drilling device for geotechnical exploration, including a base. A drilling device is provided on the base, and a through hole for the drill pipe to pass through is provided in the middle of the base; screw rods are threadedly connected at the four corners of the base. The screw rods vertically pass through the base, and a universal wheel is fixedly connected to the lower end of the screw rod. A universal wheel storage cavity for storing the universal wheel is provided at the bottom of the base. The utility model provides a drilling device for geotechnical exploration. When transporting, lower the universal wheels, and the universal wheels touch the ground for transportation. When arriving at the position where drilling is to be carried out, raise the universal wheels so that the universal wheels are hidden in the universal wheel storage cavity, and the base contacts the ground, enhancing the stability of the device, preventing displacement during the drilling process, and at the same time, vibration will not be transmitted to the screw rod of the lifting device, making the lifting device not easily damaged.

[0004] The above-mentioned drilling device needs to sequentially adjust the screw rods to retract and extend the universal wheels, which is not only laborious, but also causes the device to tilt during the adjustment process. At the same time, the drilling device is not provided with a shock absorption mechanism, the stability during the movement of the device is relatively low, and the internal parts of the device may also be damaged by vibration. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, this application provides a drilling device for geotechnical exploration, which has the advantages of being convenient for retracting and extending the universal wheels for use, reducing the labor burden of workers, being able to shock-absorb the drilling device, improving the stability of the device, and protecting the internal parts of the device, etc., and solves the problems that the existing drilling device needs to sequentially adjust the screw rods to retract and extend the universal wheels, which is not only laborious, but also causes the device to tilt during the adjustment process, and at the same time, the drilling device is not provided with a shock absorption mechanism, the stability during the movement of the device is relatively low, and the internal parts of the device may also be damaged by vibration.

[0006] To achieve the above object, the present application provides the following technical solution: A drilling device for geotechnical investigation, including a base, two first rotating shafts are rotatably inserted into the interior of the base, two first support plates are fixedly connected to the outer circumferential surface of each first rotating shaft, a first connecting rod is rotatably inserted into the interior of the first support plate, a top plate is fixedly connected to the side of the first connecting rod away from the first support plate, a sliding rod is slidably inserted into the interior of the top plate, a bottom plate is fixedly connected to the bottom surface of the sliding rod, universal wheels are provided at the bottom of the bottom plate, a spring is fixedly connected to the upper surface of the bottom plate, the upper surface of the spring is fixedly connected to the bottom surface of the top plate, dampers are fixedly connected to both ends of the bottom plate, and the top ends of the dampers are fixedly connected to the outer surface of the top plate.

[0007] Through the above solution, since the existing drilling device needs to sequentially adjust the screw to retract and extend the universal wheels, it is not only laborious, but also the device will tilt during the adjustment process. At the same time, the drilling device is not provided with a shock absorption mechanism, so the stability of the device during movement is relatively low, and the internal parts of the device may also be damaged by the vibration. By driving the first support plate and the first connecting rod to rotate through the first rotating shaft, the top plate is urged to rotate horizontally under the action of the second rotating shaft, the second support plate, and the second connecting rod, thereby automatically rotating and retracting the universal wheels, reducing the labor burden of the workers. By setting the spring and the damper, the base can be supported and shock-absorbed, improving the stability of the device during movement and protecting the internal parts of the device.

[0008] Further, four second rotating shafts are rotatably inserted into the interior of the base, a second support plate is fixedly sleeved on the outer circumferential surface of each second rotating shaft, a second connecting rod is rotatably inserted into the interior of the second support plate, and the side of the second connecting rod away from the second support plate is fixedly connected to the outer surface of the top plate.

[0009] Through the above solution, the top plate is restricted by the second rotating shaft, the second support plate, and the second connecting rod, so that the top plate remains horizontal during the rotation and retraction process.

[0010] Further, two first limiting rings are fixedly sleeved on the outer circumferential surface of each first rotating shaft, and the outer circumferential surface of each first limiting ring is rotatably connected to the interior of the base.

[0011] Through the above solution, the first rotating shaft is restricted to prevent the first rotating shaft from sliding and shifting, improving the stability of the movement of the first rotating shaft.

[0012] Further, a second limiting ring is fixedly sleeved on the outer circumferential surface of each second rotating shaft, and the outer circumferential surface of the second limiting ring is rotatably connected to the interior of the base.

[0013] Through the above solution, the second rotating shaft is restricted to prevent the second rotating shaft from sliding off, improving the stability of the movement of the second rotating shaft.

[0014] Furthermore, a first motor is fixedly connected to the right side of the base, a worm is rotatably connected to the left side of the first motor, a worm wheel is fixedly sleeved on the outer circumferential surface of each first rotating shaft, and the worm is transmission-connected to the first rotating shaft via the worm wheel.

[0015] Through the above scheme, the worm gear drives the worm wheel to rotate in the relative direction, thereby causing the first rotating shaft to rotate in the relative direction, thereby completing the rotation and retraction operation of the universal wheel.

[0016] Furthermore, two limiting rods are fixedly connected to the upper surface of each bottom plate, and the outer circumferential surfaces of the limiting rods are respectively slidably plugged into the interior of the top plate.

[0017] Through the above scheme, the top plate is restricted, so that the top plate is always lifted and lowered longitudinally, thereby improving the stability of the top plate movement.

[0018] Furthermore, a bracket is fixedly connected to the upper surface of the base, two hydraulic cylinders are fixedly connected inside the bracket, a lifting plate is fixedly connected to the output ends of the two hydraulic cylinders, a second motor is provided on the upper surface of the lifting plate, and a drill rod is rotatably connected to the bottom of the second motor.

[0019] Through the above scheme, the drill rod is driven to rotate by the second motor, and the lifting plate is driven to lift by the hydraulic cylinder, thereby driving the drill rod to lift longitudinally.

[0020] Furthermore, four columns are fixedly connected to the upper surface of the base, and the outer circumferential surface of each column is slidably connected to the inside of the lifting plate.

[0021] Through the above scheme, the lifting plate is restricted, so that the lifting plate is always lifted and lowered longitudinally, thereby improving the stability of the lifting plate movement.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The drilling device for geotechnical investigation drives the first support plate and the first connecting rod to rotate through the first rotating shaft, so that the top plate rotates horizontally under the action of the second rotating shaft, the second supporting plate and the second connecting rod, and then the universal wheel is automatically rotated and retracted, thereby reducing the workload of workers. By arranging springs and dampers, the base can be supported and shock-absorbed, the stability of the device during movement is improved, and the internal parts of the device are protected. This solves the problem that the retraction and extension of the universal wheel of the existing drilling device is relatively laborious and the device may be tilted during the adjustment process. At the same time, the drilling device is not provided with a shock-absorbing mechanism and has low stability. BRIEF DESCRIPTION OF THE DRAWINGS

A second connecting rod 11 is rotatably inserted inside the second supporting plate 10, and the second connecting rod 11 is fixedly connected to the outer surface of the top plate 5 on the side away from the second supporting plate 10. The top plate 5 is restricted by the second rotating shaft 9, the second supporting plate 10 and the second connecting rod 11, so that the top plate 5 remains flat during the rotation and retraction process.

[0033] See also Figure 3 Two first limiting rings 14 are fixedly sleeved on the outer circumference of each first rotating shaft 2, and the outer circumference of each first limiting ring 14 is connected to the internal rotation of the base 1 to limit the first rotating shaft 2, avoid sliding and deflection of the first rotating shaft 2, and improve the stability of the movement of the first rotating shaft 2.

[0034] See also Figure 3 The outer circumference of each second rotating shaft 9 is fixedly sleeved with a second limiting ring 15, and the outer circumference of the second limiting ring 15 is rotatably connected to the inside of the base 1 to limit the second rotating shaft 9, prevent the second rotating shaft 9 from sliding off, and improve the stability of the movement of the second rotating shaft 9.

[0035] See also Figure 3 A first motor 16 is fixedly connected to the right side of the base 1, and a worm 17 is rotatably connected to the left side of the first motor 16. A worm wheel 18 is fixedly sleeved on the outer circumferential surface of each first rotating shaft 2. The worm 17 is transmission-connected to the first rotating shaft 2 through the worm wheel 18, and the worm wheel 18 is driven by the worm 17 to rotate in the relative direction, thereby causing the first rotating shaft 2 to rotate in the relative direction, thereby completing the rotation and retraction operation of the universal wheel 8.

[0036] See also Figure 1 , Figure 3 and Figure 4 Two limit rods 19 are fixedly connected to the upper surface of each bottom plate 7, and the outer circumferential surfaces of the limit rods 19 are respectively slidably plugged into the interior of the top plate 5 to limit the top plate 5, so as to force the top plate 5 to always perform longitudinal lifting and lowering, thereby improving the stability of the movement of the top plate 5.

[0037] See also Figure 1 and Figure 2 A bracket 20 is fixedly connected to the upper surface of the base 1, and two hydraulic cylinders 21 are fixedly connected inside the bracket 20. A lifting plate 22 is fixedly connected to the output ends of the two hydraulic cylinders 21. A second motor 23 is provided on the upper surface of the lifting plate 22. A drill rod 24 is rotatably connected to the bottom of the second motor 23. The drill rod 24 is driven to rotate by the second motor 23, and the lifting plate 22 is driven to rise and fall by the hydraulic cylinder 21, thereby driving the drill rod 24 to rise and fall longitudinally.

[0038] See also Figure 1and Figure 2 On the upper surface of the base 1, four columns 25 are fixedly connected. The outer circumferential surface of each column 25 is slidably connected to the inside of the lifting plate 22 to restrict the lifting plate 22 and ensure that the lifting plate 22 always moves vertically, thereby improving the stability of the movement of the lifting plate 22.

[0039] In a drilling device for geotechnical investigation in this embodiment, the first rotating shaft 2 drives the first support plate 3 and the first connecting rod 4 to rotate, causing the top plate 5 to rotate horizontally under the action of the second rotating shaft 9, the second support plate 10, and the second connecting rod 11. Then, the universal wheels 8 are automatically rotated and retracted, reducing the labor burden of workers. By setting the spring 12 and the damper 13, the base 1 can be supported and shock-absorbed, improving the stability of the device during movement and protecting the internal parts of the device. This solves the problems that the retraction and adjustment of the universal wheels 8 of the existing drilling device are laborious, and the device will tilt during the adjustment process. At the same time, the drilling device is not provided with a shock-absorbing mechanism, resulting in low stability.

[0040] It should be noted that a through hole is provided in the middle of the base 1, and anti-slip teeth are fixedly connected to the bottom surface of the base 1 at equal intervals.

[0041] The working principle of the above embodiment is as follows:

[0042] When the device is performing drilling operations, the universal wheels 8 can be rotated and retracted, and the device is supported by the base 1. When the device needs to be moved after the operation is completed, the first motor 16 can be started to drive the worm 17 to rotate. The worm 17 drives the two first rotating shafts 2 to rotate in opposite directions through the worm wheel 18. The first rotating shafts 2 drive the top plate 5 to rotate towards both sides through the first support plate 3 and the first connecting rod 4. During the rotation of the top plate 5, it is always kept horizontal under the restriction of the second rotating shaft 9, the second support plate 10, and the second connecting rod 11. The top plate 5 drives the bottom plate 7 to rotate towards both sides through the sliding rod 6, and the bottom plate 7 drives the universal wheels 8 to rotate towards both sides. During the rotation of the universal wheels 8, the base 1 is supported, facilitating the movement of the device. When drilling operations need to be performed again, only the first motor 16 needs to be started to output reverse power to drive the universal wheels 8 to rotate and retract, and the base 1 is placed on the ground. The spring 12 and the damper 13 can support and shock-absorb the device, buffer the vibration and impact received during the movement of the device, and improve the stability of the device during movement. The drill rod 24 can be rotated by the second motor 23, and the lifting plate 22 can be lifted and lowered by the hydraulic cylinder 21, thereby driving the drill rod 24 to move vertically.
