Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that in order to meet the requirements of drilling depth, drilling is often completed through a long drill pipe at one time, that is, the operator only needs to disassemble and assemble the drill pipe once, but due to the frequent occurrence of safety accidents and Now the requirements for construction safety are gradually increasing, so the height of the guide column has been limited in many areas (the length of a single drill pipe is limited)
In order to meet the drilling depth and height, multiple short drill pipes are required to be connected sequentially for drilling pipes, so multiple disassembly and assembly are required, which greatly increases the difficulty of construction and the risk factor

Embodiment 1

[0053] Such as figure 1 As shown, a kind of drilling equipment comprises frame 100, winch 103, drill pipe dismounting auxiliary device 10, muddy water conveying device 200 and muddy water mixing system 300, wherein frame 100 is equipped with vertically arranged guide post 102, guide post 102 is equipped with a power head 104, and the winch 103 controls the lifting and moving of the power head 104, and the power head 104 is equipped with a drill pipe 105.

[0054] During use, the crane lifts the drill pipe 105 to the drill pipe dismounting auxiliary device 10, the drill pipe dismounting auxiliary device 10 will grab the drill pipe 105, and move the drill pipe 105 to the bottom of the power head 104, and then put the drill pipe 105 It is matched with the power head 104 and installed; then the power head 104 drives the drill pipe 105 to rotate and move down to complete a drilling; after a drilling is completed, the installation between the power head 104 and the first drill pipe ...

Embodiment 2

[0085] Such as Figure 11 As shown, the following settings are made on the basis of Embodiment 1. The auxiliary device 10 for drilling pipe disassembly and assembly also includes a monitoring component 106. The monitoring component 106 can be installed on the body of the power head 104, and the monitoring component 106 can also be installed on the guide column 102. Above, the monitoring component 106 may be a monitoring device such as a camera, an infrared distance measuring device, or the like.

[0086] The monitoring component 106 is used to monitor the cooperation between the drill pipe 105 and the power head 104, which is convenient for the operator to remotely monitor the cooperation between the drill pipe 105 and the power head 104, so as to adjust the position of the drill pipe 105 or the power head 104 according to the cooperation , thereby ensuring the accuracy of the drill rod 105 dismounting, and relatively safe.

Embodiment 3

[0088] Such as Figure 12 As shown, the difference from Embodiment 1 is that the part of the fixed claw part 21 away from its own claw mouth is slidably connected with the mounting base 1, and the sliding direction of the fixed claw part 21 is horizontally close to or away from the vertical direction of the power head 104. Set to the path; the first drive assembly 13 is a linear reciprocating drive mechanism such as an air cylinder, a hydraulic cylinder, and a motor screw drive structure. One end of the first drive assembly 13 is fixedly connected to the mounting base 1, and the other end of the first drive assembly 13 is fixed to the mounting base 1. The claw portion 21 is fixedly connected, that is, the first driving assembly 13 drives the clamping claw 2 to move by horizontal sliding, so as to realize the position adjustment of the drill rod 105 .

Abstract

The invention relates to the field of engineering equipment, in particular to a drill rod disassembly and assembly auxiliary device and drilling equipment. According to the main technical scheme, the drill rod disassembly and assembly auxiliary device comprises a mounting base and a clamping jaw, the mounting base is used for being connected with a guide column, the clamping jaw is movably connected with the mounting base, a first driving assembly used for driving the clamping jaw to move is arranged between the mounting base and the clamping jaw, the clamping jaw is provided with a second driving assembly, and the second driving assembly is used for controlling opening and closing of the clamping jaw. By means of the clamping jaw with maneuverability, the position of a drill rod can be adjusted, so that alignment connection between the drill rod and a power head is facilitated, the step of manual adjustment is omitted, and then the construction difficulty and the danger coefficient are reduced.

Description

technical field [0001] The present application relates to the field of engineering equipment, in particular to an auxiliary device for disassembling and assembling a drill pipe and drilling equipment. Background technique [0002] Drilling equipment is often required during piling construction. The drilling equipment includes a frame, a guide post, a hoist and a power head, the power head and the guide post are vertically slidably connected, the power head is equipped with a drill pipe, and the hoist is used to control the vertical movement of the power head. [0003] When in use, use the crane to hoist the drill pipe to the position corresponding to the power head, and then the operator climbs to a certain height and manually adjusts the position of the drill pipe to facilitate alignment with the power head and subsequent installation. [0004] In view of the above-mentioned related technologies, the inventor believes that in order to meet the requirements of drilling dept...
