Oil cylinder device achieving automatic pin insertion and long screw drilling rig

Abstract

The invention provides an oil cylinder device achieving automatic pin insertion and a long screw drilling rig and belongs to the field of drilling rigs. The oil cylinder device achieving automatic pininsertion comprises a guide piece provided with a first open hole, a sliding piece connected with the guide piece in a sliding manner and provided with a second open hole, a pin insertion assembly, adetecting piece and a controller, wherein the pin insertion assembly comprises an inserted pin piece and a pushing piece, wherein the inserted pin piece is connected with the pushing piece, the pushing piece is used for pushing an inserted pin to move in the direction close to the first open hole or the direction far away from the first open hole so as to be inserted into the second open hole orpulled out of the second open hole, the detector is used for detecting the overlap ratio between the first open hole and the second open hole and the insertion distance of the inserted pin piece in the second open hole, and the controller is used for controlling the pushing piece to work according to detection signals of the detector. By the adoption of the oil cylinder device achieving automaticpin insertion and the long screw drilling rig, automatic insertion of the inserted pin can be achieved, it can be ensured that the inserted pin reaches the preset work position, and the inserted pin can be automatically pulled out.

Description

technical field [0001] The invention relates to the field of drilling rigs, in particular to an oil cylinder device for automatic bolting and a long auger drilling rig. Background technique [0002] At present, the latch device is widely used in the field of construction machinery, but it is usually difficult for the latch device to accurately locate the position of the latch, and at the same time it is difficult to automatically perform the latch. The latch is usually manual, and the latch position is relatively low. When the latch is at a high position, it is difficult plug. [0003] However, there are the following problems in the prior art. The oblique support of the existing common rotary drilling rig has the following disadvantages: the oblique support is difficult to automatically insert the pin; the latch device is difficult to automatically pull out after being plugged in; Contents of the invention [0004] The present invention provides an automatic plug-in oil ...
