[0034] Example:

[0035] like Figures 1 to 7 A downhole drilling lifting platform includes a column 10, a lifting frame 20, and a mobile drilling platform 30.

[0036] In this embodiment, the main body of the column 10 is made of I-beam, and an upper guide plate 12 is provided at the top of the column. The upper guide plate 12 is provided with a lifting frame guide hole 11, and the lifting frame guide hole 11 is a square hole, and the lifting frame guide hole protrudes from the main body of the column. A slot 13 is also provided at the top of the column, and a lifting cable pulley 52 is installed on the lower side of the upper guide plate, and the lifting cable pulley 52 is located in the slot 13.

[0037] The lifting frame is provided with a lifting column 23, a crossbeam 21 is provided at the top of the lifting column, and a lifting seat 22 is provided at the lower end of the lifting column. In this embodiment, the lifting column adopts a square steel pipe corresponding to the lifting frame guide hole 11 of the column, and the crossbeam adopts a channel steel structure. In order to facilitate assembly, the lifting seat 22 and the lifting column 23 are movably installed, and the lifting seat 22 is provided with a lifting column connecting groove 25. The lower end of the lifting column 23 is fixed in the lifting column connecting groove 25, and the connection between the lifting seat 22 and the lifting column 23 can be further fixed by bolts 27. In order to make the lifting frame have a more stable overall structure, a crossbeam support rod 26 is provided between the lifting seat and the crossbeam. The crossbeam support rod 26 adopts a steel pipe, and the two ends are respectively hinged to the lifting seat 22 and the crossbeam 21. The lifting seat 22 is provided with a sliding sleeve 24, and the sliding sleeve 24 is slidably matched with the column 10, and the lifting column 23 is slidably matched with the lifting frame guide hole 11 of the column, so that the lifting frame 20 can move up and down along the column 10.

[0038] The mobile drilling platform 30 is installed on the cross beam 21. The lower side of the mobile drilling platform is provided with a slide groove 33 and a slide groove bottom plate 34 that slide with the cross beam 21, so that the mobile drilling platform 30 moves along the cross beam 21. A drilling rig 80 is installed on the mobile drilling platform.

[0039] The mobile drilling floor 30 is pulled by the drilling floor traction cable. A drilling floor traction winch 40 is provided on the lifting seat 22, a front traction pulley 43 is provided at the front end of the crossbeam 21, and a rear traction pulley 44 and a steering pulley 45 are provided at the rear end of the crossbeam. The drilling floor traction cable includes a front traction section 41 and a rear traction section 42. The front end 31 of the mobile drilling floor is provided with a cable connector. The front traction section 41 is connected to the front end 31 of the mobile drilling floor, then goes around the front traction pulley 43, then goes along the crossbeam 21 to the steering pulley 45, then goes around the steering pulley 45 and is connected downward to the drilling floor traction winch 40. The rear front end 32 of the mobile drilling floor is also provided with a cable connector.

When the traction winch 40 of the drilling floor rotates, if the traction winch 40 of the drilling floor pulls the front traction section 41, the rear traction section 42 will be loosened, and the mobile drilling floor 30 will move forward along the cross beam (in the direction of the forward traction pulley 43). On the contrary, if the traction winch 40 of the drilling floor pulls the rear traction section 42, the front traction section 41 will be loosened, and the mobile drilling floor 30 will move backward along the cross beam (in the direction of the rear traction pulley 44).

[0045] like Figure 7 As shown, the underground drilling lifting platform is arranged on an underground trackless rubber-wheeled vehicle 70. The base 60 is fixed on the underground trackless rubber-wheeled vehicle 70, and the column 10 is erected on the underground trackless rubber-wheeled vehicle through the base 60, and the underground drilling lifting platform can move with the underground trackless rubber-wheeled vehicle as a whole.

[0046] During the underground drilling operation, the underground trackless rubber-wheeled vehicle carrying the underground drilling lifting platform is driven to the drilling position, the drilling rig is installed on the mobile drilling platform, and the front column support rod and the rear column support rod are operated to adjust the column angle to match the drilling inclination. Then the lifting frame is raised to reach the specified drilling height. The drilling rig is started and the mobile drilling platform is operated to drill. After the drilling is completed, the mobile drilling platform is operated to withdraw the drilling rig.

[0047] The utility model adopts a lifting frame to mechanically raise the height of the drilling rig, and uses a mobile drilling platform to operate the drilling rig for drilling, thereby realizing the mechanical positioning operation of underground drilling, reducing labor intensity, and improving construction efficiency and safety. The device is installed on a trackless rubber-wheeled vehicle to meet the environmental requirements of underground operations.
