Description

Technical Field

[0001] This utility model relates to the field of pipe mounting equipment technology, and in particular to a pipe mounting device for a drilling rig with a double drill rod casing. Background Technology

[0002] On January 31, 2024, the applicant filed a patent application entitled "A Pipe Mounting Device Installed on a Drilling Rig," which specifically discloses a device including a square pipe frame, a slide table, and a gripping mechanism. The square pipe frames are symmetrically arranged, and the slide table is located on two square pipe frames. A storage rack is provided on each side of the slide table, and each storage rack is mounted on the square pipe frame through two sleeves. The gripping mechanism includes a longitudinal slide rail, a transverse slide rail, a slider, a mounting block, a mechanical gripping arm, and a connecting block. The transverse slide rail is movably mounted on the longitudinal slide rail through the slider, and a second hydraulic cylinder is provided at the lower part of the longitudinal slide rail. The output shaft of the second hydraulic cylinder is connected to the lower end of the mounting block. The mechanical gripping arm is connected to the side of the mounting block. The lower part of the longitudinal slide rail is rotatably connected to the connecting block through a rotating shaft, and the connecting block is mounted on the side of the slide table.

[0003] In use, the slide is driven to move by the first hydraulic cylinder, and the storage rack is equipped with four vertical rods. A groove for storing drill rods is formed between two vertical rods. When the above-mentioned pipe mounting device is installed on the drilling machine, the drill rod on the square pipe rack can be grabbed by the gripping mechanism and installed on the drilling machine, saving workers the time of carrying drill rods. However, the drilling machine needs to drill not only horizontally, but sometimes also in an inclined or vertical direction. The pipe mounting device can only realize horizontal pipe mounting, which is difficult to meet the needs of the drilling machine. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The middle part of the swing frame is hinged to the lower end of the connecting rod. The horizontal direction is defined as extending along the length of the swing frame, and the longitudinal direction is defined as extending along the width of the swing frame.

The two ends of the sixth linear drive mechanism are respectively hinged to the fixed tube and the sliding rod.

[0010] Furthermore, the fixed tube includes an upper sleeve and a lower sleeve that are rotatably connected, and a first positioning component is provided between the upper sleeve and the lower sleeve.

[0011] Furthermore, the crossbar includes a first rod and a second rod that are rotatably connected, and a second positioning component is provided between the first rod and the second rod.

[0012] Furthermore, the upper end of the connecting rod is rotatably connected to the other end of the crossbar, and a third positioning component is provided between the connecting rod and the crossbar.

It can be used for drilling rigs of different specifications and has a wide range of applications. Attached Figure Description

The horizontal direction is defined as extending along the length of the swing frame 4, and the longitudinal direction is defined as extending along the width of the swing frame 4. The two ends of the first linear drive mechanism 8 are respectively hinged to the upper part of the connecting rod 3 and the lateral side of the swing frame 4. The first guide assembly 11 is disposed on the lateral side of the swing frame 4 and is distributed in the lateral direction. The first clamping frame 6 is disposed on the first guide assembly 11. The first clamping assembly 12 is disposed on the first clamping frame 6. The second linear drive mechanism 9 is connected to the first clamping frame 6 and is used to drive the first clamping frame 6 to reciprocate along the guiding direction of the first guide assembly 11. The middle part of the swing rod 5 is hinged to the other lateral side of the swing frame 4.

The second clamping frame 7 is disposed at the lower end of the swing rod 5. The second clamping assembly 13 is disposed on the second clamping frame 7.

[0022] The upper casing device of this drilling rig's double drill pipe casing uses a first clamping assembly 12 and a second clamping assembly 13 to clamp the outer casing and inner drill pipe of the drilling rig, respectively, and transfer them to the periphery of the drilling rig. A first linear drive mechanism 8 drives a swing frame 4 to swing, so that the outer casing and inner drill pipe are distributed in an inclined direction or vertically, thus adapting to the drilling angle of the drilling rig. The second clamping assembly 13 then places the inner drill pipe onto the drilling rig. A third linear drive mechanism 10 drives a second clamping frame 7 to swing upwards, thereby causing the second clamping assembly 13 to swing upwards, and then the second linear drive assembly 9 drives... The first clamping assembly 12 moves along the guiding direction of the first guiding assembly 11, sleeves the outer sleeve onto the inner drill pipe, and places the outer sleeve onto the drilling rig through the first clamping assembly 12, thus realizing the upper casing of the drilling rig's double drill rod casing. Of course, the upper casing can also be realized by the first clamping assembly 12 and the second clamping assembly 13 clamping the same casing together. This upper casing device can realize the upper casing in the inclined direction or vertical direction and the upper casing of the drilling rig's double drill rod casing through multi-angle adjustment and separate control of the first clamping assembly 12 and the second clamping assembly 13. It can be used for drilling rigs of different specifications and has a wide range of applications.

[0023] Furthermore, the first clamping assembly 12 includes a second guide assembly 121, a fourth linear drive mechanism 122, a first fixed clamping member 123, and a first movable clamping member 124. The first fixed clamping member 123 is disposed on one longitudinal side of the first clamping frame 6, and the second guide assembly 121 is disposed on the other longitudinal side of the first clamping frame 6. The second guide assembly 121 is distributed along the longitudinal direction, and the first movable clamping member 124 is disposed on the second guide assembly 121.

The first movable clamping member 124 and the second movable clamping member 134 are driven to move by the fourth linear drive mechanism 122 and the fifth linear drive mechanism 132 respectively, so that they cooperate with the first fixed clamping member 123 and the second fixed clamping member 133 respectively, to realize the clamping of the drill pipe casing with good stability.

[0024] Meanwhile, the column 1 includes a fixed tube, a sliding rod 101, and a sixth linear drive mechanism 102. The sliding rod 101 passes through the upper part of the fixed tube and can slide along the axial direction of the fixed tube. The two ends of the sixth linear drive mechanism 102 are respectively hinged to the fixed tube and the sliding rod 101. The fixed tube includes an upper sleeve 103 and a lower sleeve 104 that are rotatably connected. A first positioning component 105 is provided between the upper sleeve 103 and the lower sleeve 104 to realize the extension, retraction, and rotation of the column 1, thereby driving the horizontal bar 2 to move up and down and swing, and improving the range of motion of the swing frame 4.

[0025] Furthermore, the crossbar 2 includes a first rod body 201 and a second rod body 202 that are rotatably connected.
