Description

Technical Field

[0001] The utility model relates to the technical field of drilling rig equipment, in particular to a new type of all-hydraulic drilling rig. Background Technique

[0002] The hydraulic drilling rig for geological exploration is an advanced drilling equipment driven by the hydraulic principle. It converts the liquid pressure into mechanical power through the hydraulic system;

[0003] The hydraulic system of the hydraulic drilling rig converts the oil into high-pressure oil through the hydraulic pump, and then transmits it to the actuators such as hydraulic motors and hydraulic cylinders through the hydraulic pipeline to drive the drill pipe to rotate and lower, so as to complete the drilling operation. For example, the Chinese utility model patent disclosed in the publication number CN211851663U: A crawler-type multi-functional all-hydraulic drilling rig. This application includes a mobile frame, a vertical guide rail, a winch with a steel wire rope and a power head assembly. Two opposite hydraulic outriggers are respectively arranged at the front end and the rear end of the mobile frame. The vertical guide rail is arranged in the middle of the front end of the mobile frame. A mobile base that can freely move up and down on the vertical guide rail is arranged on the vertical guide rail. The winch with a steel wire rope is arranged on the mobile frame. The power head assembly includes a power head fixing frame, a hydraulic impact power head and a hydraulic rotary power head. The hydraulic impact power head in the drilling rig can meet the requirements of impact soil sampling operation. The hydraulic rotary power head in the drilling rig can meet the requirements of rotary coring and rotary well drilling. When drilling holes in the formation, since the excavation of some holes has a certain depth, multiple drill pipes need to be connected to achieve deep-hole drilling. However, when hoisting the subsequent drill pipes through the cooperation of the mobile base and the hydraulic rotary power head, the drilling bottom that has penetrated into the formation cannot be quickly calibrated and docked with one end of the drill pipe to be connected, so manual pushing and pulling calibration is required, resulting in low connection efficiency of the drilling and increasing the labor intensity of workers. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of all-hydraulic drilling rig, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0012] Based on this, by means of the arrangement of the rotatable guide roller, when the drill pipe is hoisted later, the bottom of the drill pipe can smoothly move onto the two guide seats.

Pressing grooves are respectively formed on the opposite sides of the two guiding seats, the slider is slidably installed in the corresponding sliding groove, and the guiding shaft penetrates through the through hole in the slider. A compression spring is sleeved on the guiding shaft between one side in the sliding groove and the slider.

[0015] Based on this, two guiding seats are movably installed on the front side of the first mounting seat, so that after the bottom of the drill pipe moves to the positions of the two pressing grooves, the two guiding seats can be respectively extruded and moved to one side, thereby facilitating the docking of the joints of the two drill pipes.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] In the present utility model, an installation frame is arranged on the front side of the column, which can cooperate with the hydraulic cylinder and the clamping block to clamp and fix the drill pipe.

The inserting pipe device 6 includes a mounting frame 7, hydraulic cylinders 8 are fixedly installed on both sides of the mounting frame 7, and the hydraulic pipe-rubbing power head 5 and the hydraulic cylinders 8 are respectively connected to the hydraulic station 2 through hydraulic pipes. A guide roller 9 is movably installed on the front side of the mounting frame 7, and a first mounting seat 10 is fixedly installed on the mounting frame 7 at a position behind the guide roller 9. Two guide seats 11 are movably installed on the front side of the first mounting seat 10.

[0025] As Figures 2-3 shown, the output ends of the two hydraulic cylinders 8 respectively pass through the mounting frame 7 and are fixedly installed with clamping blocks 12. With the arrangement of the two groups of hydraulic cylinders 8 and the clamping blocks 12, one end of the drill pipe can be clamped and limited. A second mounting seat 13 is fixedly installed on the front side of the mounting frame 7, and two shaft seats 14 are fixedly installed on the second mounting seat 13. Installing the two shaft seats 14 on the front side of the mounting frame 7 can provide conditions for the rotational installation of the guide roller 9. Rotating shafts 15 are fixedly installed at the central positions on both sides of the guide roller 9, and the rotating shafts 15 are rotatably installed in the corresponding shaft seats 14, that is, the guide roller 9 is rotatably installed between the two shaft seats 14 through the rotating shafts 15 on both sides. With the arrangement of the rotatable guide roller 9, when the drill pipe is hoisted later, the bottom of the drill pipe can be smoothly moved onto the two guide seats 11;

[0026] As Figures 3-4As shown, a base 16 is fixedly installed at the bottom of the first mounting seat 10. Two support triangular plates 17 are fixedly connected between the first mounting seat 10 and the base 16. Two sliding grooves 18 are formed in the first mounting seat 10. A guide shaft 19 is fixedly connected between the two sliding grooves 18. The base 16 is fixedly installed on the mounting frame 7. Sliders 20 are respectively fixedly installed at the rear sides of the two guide seats 11. A support seat 21 is fixedly installed at the bottom of the guide seat 11. A limit seat 22 is fixedly installed at the bottom of the support seat 21.

And when the bottom of the second drill pipe moves to the position of the pressing groove 23 on the opposite sides of the two guide seats 11, it is inserted between the two pressing grooves 23 by means of the gravity of the drill pipe itself, thereby respectively extruding and moving the two pressing grooves 23 to one side. Then, the sliders 20 at the rear sides of the two support seats 21 slide in the sliding grooves 18 and compress the compression spring 24 towards one side in the sliding grooves 18, and the support seat 21 slides on the top of the second mounting seat 13 through the limit seat 22 at the bottom and the balls, so that the two guide seats 11 are separated and the bottom of the second drill pipe passes through the two guide seats 11 and contacts the top of the first drill pipe, thereby connecting the two drill pipes.
