Three-chuck clamping system device

Abstract

The invention relates to a three-chuck clamping system device. The three-chuck clamping system device comprises a main chuck, a gyrator and lifting oil cylinders. The three-chuck clamping system device is characterized in that the main chuck is provided with a connecting guide rod, the connecting guide rod penetrates through an upper chuck mounting plate, and the upper chuck mounting plate can only move in a lifting mode on a guide segment of the connecting guide rod. An upper chuck is arranged over the main chuck, and the upper chuck is located underneath the upper chuck mounting plate and fixedly mounted on the upper chuck mounting plate. Shackling oil cylinders are arranged on the periphery of the upper chuck. Shackling oil cylinder bodies are fixedly connected to the connecting guide rod. Piston rod ends of the shackling oil cylinders are upwards connected to the upper chuck mounting plate. The upper ends of guide rods are connected to the periphery of the upper chuck mounting plate, the guide rods are placed in guide sleeves, and the guide sleeves are fixed to the gyrator. The lower ends of the guide sleeves are connected with the tail ends of thrust oil cylinder bodies. Piston rod ends of thrust oil cylinders are downwards connected with a lower chuck mounting plate. A lower chuck is mounted at the bottom of the lower chuck mounting plate. The lower chuck and the main chuck are coaxial. The three-chuck clamping system device can achieve automatic shackling, so labor intensity is lowered, and working efficiency is improved.

Description

technical field [0001] The invention relates to a tunnel drilling rig, in particular to a three-chuck clamping system device on the tunnel drilling rig, and belongs to the technical field of drilling engineering machinery. Background technique [0002] At present, tunnel drilling rigs are equipment for drilling construction in tunnels. There are mainly three types of existing tunnel drilling rigs: the first type is ordinary engineering core surface drilling rigs. This kind of drilling rig has no upper and lower clamping devices. When the drilling rig is drilling upwards, the drill pipe is easy to slide down because there is no hole holder; the second type is a bulk tunnel drilling rig, which has small drilling capacity and poor stability; the third type is Full-hydraulic drilling rigs. At present, some of these drilling rigs are imported. The price of imported full-hydraulic drilling rigs is high, the maintenance cost is high, and the operation level of the captain is very h...

[0002] At present, tunnel drilling rigs are equipment for drilling construction in tunnels. There are mainly three types of existing tunnel drilling rigs: the first type is ordinary engineering core surface drilling rigs. This kind of drilling rig has no upper and lower clamping devices. When the drilling rig is drilling upwards, the drill pipe is easy to slide down because there is no hole holder; the second type is a bulk tunnel drilling rig, which has small drilling capacity and poor stability; the third type is Full-hydraulic drilling rigs. At present, some of these drilling rigs are imported. The price of imported full-hydraulic drilling rigs is high, the maintenance cost is high, and the operation level of the captain is very high; there are also some domestically-made full-hydraulic drilling rigs, but the quality of domestic production is not particularly good. , and there is no compensating device for removing the drill pipe, it is easy to damage the screw thread, etc.
