Description

Auxiliary fastener for drilling of engineering geological drilling rig

Technical Field

The utility model relates to an engineering geology drilling machine is bored supplementary fastener down.

Background

Most of the prior engineering geological drilling requires full-face coring, and the situation of difficult drilling can occur when an engineering geological drilling machine is used.

When the engineering geological drilling rig drills, the engineering geological drilling rig drives a vertical shaft to rotate through a power head of the engineering geological drilling rig, a hydraulic lifting device is arranged on the power head, the vertical shaft is driven to lift through the hydraulic lifting device, a first connector at the lower end of the vertical shaft is connected with a second connector at the upper end of a drill rod, so that the drill rod is driven to rotate to drill a hole downwards, wherein the first connector and the second connector are cylindrical, two opposite first bayonets are arranged on the side surface of the first connector, and two opposite second bayonets are arranged on the side surface of the second connector. After the lower end of the vertical shaft extends into the ground to a certain depth, if drilling is to be continued, the vertical shaft needs to be lifted upwards, the drilled drill rod is left in the hole, then the power head is rotated to the side to move away, the next drill rod is inserted into the hole, then the power head is reset, the inserted next drill rod is connected with the lower end of the vertical shaft, and drilling is continued downwards. In the process of lifting the vertical shaft upwards or after the vertical shaft is lifted, soft soil (silt, mucky soil and the like) and expansive clay can cause shrinkage cavities, and sand layers can often cause hole collapse, so that the next drill rod is difficult to insert into a hole, and the upper end of the drill rod which is not inserted in place is higher than the lower end of the vertical shaft and cannot be connected with the lower end of the vertical shaft, and further drilling cannot be continued. One conventional treatment method is to re-drill holes, commonly called "hole sweeping"; the other method is to press the drill rod by the self gravity of the human body until the drill rod reaches the bottom elevation. Such operation is inefficient and dangerous. Therefore, the auxiliary fastener for drilling is convenient and quick to research and simple to operate, and has important significance.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1 to 8, the auxiliary fastener for drilling of the engineering geological drilling machine comprises a linear telescopic mechanism, an upper clamping arm 4, an upper caliper 5, a lower clamping arm 6 and a lower caliper 7, wherein the linear telescopic mechanism can be linearly telescopic and locked, one end of the upper clamping arm 4 and one end of the lower clamping arm 6 are respectively connected with two ends of the linear telescopic mechanism, the other end of the upper clamping arm 4 and the other end of the lower clamping arm 6 extend towards two opposite sides, the upper caliper 5 is fixed at the other end of the upper clamping arm 4, an upper jaw 10 for being clamped at a second bayonet 103 on a second connector 101 of a drill rod is arranged on the upper caliper 5, the lower caliper 7 is fixed at the other end of the lower clamping arm 6, and a lower jaw 11 for being clamped at a first bayonet 104 of a first connector 102 of a vertical shaft of the engineering geological drilling machine is arranged on the lower caliper 7.
