Embodiment Construction
[0020] The present invention will be further explained below in conjunction with the drawings.
[0021] As attached Figure 1-5 As shown, a drilling rig column assembly maintenance work device includes a support leg 1, a swing cylinder 5, a mounting shaft 2, an extension beam 4, and the mounting shaft 2 is vertically arranged on the upper part of the front face of the support leg 1 and located at the connecting portion 3. Below; the extension beam 4 is provided on the upper side of the supporting leg 1;
[0022] The mounting shaft 2 is used to install the drilling rig column assembly 12, the cylinder body of the swing cylinder 5 is installed on the drilling rig column assembly 12, and its piston rod is connected with the extension beam 4, and the expansion and contraction of the piston rod makes the drilling rig The column assembly 12 rotates around the mounting shaft 2.
[0023] The drilling rig is provided with a lifting mechanism; the top end of the supporting leg 1 is provided ...

The invention discloses a drilling machine column assembly maintenance working device which comprises a support leg, a swing cylinder, a mounting shaft and an extension beam. The mounting shaft is vertically arranged on the upper portion of the front of the support leg and positioned below a connecting portion, the extension beam is arranged on the upper portion of the side face of the support leg, the mounting shaft is used for mounting a drilling machine column assembly, a cylinder body of the swing cylinder is mounted on the drilling machine column assembly, a piston rod is connected with the extension beam, and the drilling machine column assembly rotates around the mounting shaft through extension and retraction of the piston rod. When the drilling machine column assembly needs maintenance, the drilling machine column assembly rotates to a horizontal direction, the support leg descends to the ground and functions in supporting under the action of a drilling machine lifting mechanism, and a drilling machine can be maintained. The drilling machine column assembly maintenance working device is reasonable in design, and the maintenance efficiency of the drilling machine column assembly and safety of maintainers can be improved.
Description
Technical field [0001] The invention belongs to the technical field of drilling equipment, and specifically relates to a maintenance work device for a drilling rig column assembly. Background technique [0002] With the development of science, drilling rigs are also widely used in various fields, making the use of drilling rigs more frequent. After years of development, the design and manufacture of drilling rigs have become mature. However, engineering practice has proved that there are still some problems with drilling rigs during construction. The rig body is installed on the boom of the rig and can be rotated under the action of hydraulic components. In the prior art, when the rig body needs to be repaired, the rig body is rotated to an angle suitable for maintenance, but the maintenance process lacks support It is not convenient for maintenance personnel to perform maintenance operations, and the safety factor of maintenance personnel is also low. Summary of the invention...
