In actual application, the base plate is placed on an inclined ground plane, and then the gantry is rotated so that the drill bit is perpendicular to the horizontal plane and then limited and fixed by the limit device.

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown, an embodiment of the utility model proposes a new type of drilling rig for geological survey, which includes a gantry 1 with a base plate 4 rotatably arranged at the bottom; a travel seat 3 slidably arranged on the gantry 1, and a drilling device is arranged on the travel seat 3; a driving device is arranged on the gantry 1 and connected to the travel seat 3, and the driving device is used to drive the travel seat 3 to move up and down along the gantry 1; two sets of limit devices are respectively arranged at the connection between the gantry 1 and the base plate 4, and are used to adjust the angle between the gantry 1 and the base plate 4.

[0022] The detailed working process of this embodiment is as follows: the travel base 3 is used to mount the drilling device. The gantry 1 is rotatably connected to the base plate 4. Two sets of limiters adjust and control the angle between the gantry 1 and the base plate 4, allowing the gantry 1 to form and maintain an angle with the base plate 4. This ensures that the drill rod remains perpendicular to the horizontal plane during drilling operations, reducing the workload of the operator. In actual use, the base plate 4 is placed on an inclined ground plane, and the gantry 1 is then rotated to make the drill rod perpendicular to the horizontal plane. The limiters then secure the drill rod in place. Finally, the driving device drives the drilling device downward to perform the drilling operation.

[0023] like Figure 1 As shown, the drilling device includes a driving source 302 arranged on the travel seat 3 and a drill bit 303 connected to the driving source 302 in a transmission manner. The drilling end of the drill bit 303 is close to the base plate 4.

[0024] The detailed working process of this embodiment is as follows: the driving source 302 is used to drive the drill bit 303 to rotate. The driving source 302 in this embodiment is driven by a motor. In other embodiments, a reasonable driving device can be selected according to actual conditions.

[0025] like Figure 1As shown in the figure, the driving device includes two chains 301 that are mirror - arranged on both sides of the driving source 302 and are located inside the gantry 1, a rotating shaft 2 rotatably arranged at the upper part of the gantry 1, and two short shafts 103 rotatably arranged at both ends of the lower part of the gantry 1 respectively. Among them, gears 201 are rotatably arranged at both ends of the rotating shaft 2 and on the two short shafts 103. Each chain 301 is respectively meshed with the corresponding gear 201, and both ends of each chain 301 are fixedly connected to the stroke seat 3.

[0026] The detailed working process of this embodiment is as follows: Each chain 301 is respectively meshed with a gear 201 on the rotating shaft 2 and a gear 201 on the short shaft 103, and both ends of each chain 301 are arranged on the stroke seat 3. By rotating the rotating shaft 2, the chain 301 is driven to drive the stroke seat 3 to move up and down.

[0027] As Figure 1 shown Figure 2 As shown in the figure, each limiting device includes a connecting seat 5 fixedly arranged at the lower end of the gantry 1 and a limiting seat 501 fixedly arranged on the bottom plate 4. The connecting seat 5 and the limiting seat 501 are movably connected through a connecting shaft 503. Among them, an eccentric block 502 is rotatably arranged at one end of the connecting shaft 503, and the limiting seat 501 abuts against the connecting seat 5 under the extrusion of the eccentric block 502.

[0028] As Figure 2 shown, both the limiting seat 501 and the connecting seat 5 are provided with engaging teeth, the engaging teeth are meshed with each other, and the limiting seat 501 is made of an elastic material.

[0029] The detailed working process of this embodiment is as follows: The limiting seat 501 is made of an elastic material and can move away from the connecting seat 5 without external force, or can approach the connecting seat 5 through external extrusion. It is fixed by the mutual meshing of the engaging teeth on the limiting seat 501 and the connecting seat 5 to prevent the gantry 1 from rotating. When in use, first rotate the eccentric block 502 to make it lose pressure, then the limiting seat 501 moves away from the connecting seat 5 under its own elastic force. At this time, the gantry 1 can be rotated to adjust the angle between the gantry 1 and the bottom plate 4. After adjusting to the appropriate position, rotate the eccentric block 502 in the reverse direction to squeeze the limiting seat 501 so that it is clamped on the connecting seat 5.

[0030] As Figure 3 shown, hexagonal prisms 202 are arranged at both ends of the rotating shaft 2, and a rotating disk 203 is detachably arranged on any one of the hexagonal prisms 202.

[0031] The detailed working process of this embodiment is as follows: Rotating the rotating disk 203 drives the rotating shaft 2 to rotate, thereby driving the stroke seat 3 to move. The rotating disk 203 is detachably arranged on any one of the hexagonal prisms 202, and can be installed on the corresponding hexagonal prism 202 for operation according to the standing position of the staff.

[0032] As Figure 1 shown, scale lines 102 are provided on the gantry 1.

[0033] The detailed working process of this embodiment is as follows: With the scale lines 102 provided, the depth of the drilled hole can be visually measured. Marking the scale on the gantry 1 can help the operator track the progress and depth of the drilling, ensuring that the drilled hole reaches the predetermined depth.

[0034] As Figure 1 shown, an extension arm 401 is provided on one side of the bottom plate 4, and rollers 402 are provided on the extension arm 401.

[0035] The detailed working process of this embodiment is as follows: With the rollers 402 provided, it can provide convenience during on-site construction, reduce the physical strength required for manual handling, reduce the labor intensity, and improve work efficiency.

[0036] As Figure 1 shown, a rubber pad 101 is sleeved on the upper end of the gantry 1.

[0037] The detailed working process of this embodiment is as follows: With the rubber pad 101 provided, it can provide a better grip, increase the friction between the hand and the handle. At the same time, the rubber pad 101 can absorb the vibration during the pushing and pulling process, reducing the impact on the wrist and arm.

[0038] The implementation principle of this application embodiment is as follows: First, place the bottom plate 4 on the ground. Depending on whether the ground is inclined, decide whether to adjust the gantry 1. When adjustment is needed, first rotate the eccentric block 502 to make it lose pressure. Then, the limit seat 501 moves away from the connecting seat 5 under its own elastic force. At this time, the gantry 1 can be rotated to adjust the angle between the gantry 1 and the bottom plate 4. After adjusting to the appropriate position, rotate the eccentric block 502 in the reverse direction to squeeze the limit seat 501 so that it is clamped on the connecting seat 5. Then, power on the drive source 302, and finally drive the drill bit 303 to perform drilling work by rotating the rotating disk 203.
