An intelligent shaft sinking derrick

Abstract

The invention discloses a vertical shaft sinking headframe. The vertical shaft sinking headframe comprises a headframe support body, a base support and a head sheave platform, wherein the headframe support body comprises a headframe support body I and a headframe support body II; the lower part of the headframe support body I is connected to the base support through a force measuring node; the upper part of the headframe support body I is connected with the lower part of the headframe support body II through a force measuring node; the upper part of the headframe support body II is connected to the head sheave platform through a force measuring node; the force measuring nodes are connected to a monitoring and warning module through a data line or a wireless network. Compared with the existing shaft sinking headframe, the force measuring nodes which are arranged at the lower end of the head sheave platform, the lower end of the headframe support body II and the lower end of the headframe support body I can be used for monitoring the construction load of the shaft sinking headframe and the stress state of main components in real time and warning when the construction load is close to the designed bearing force of the headframe, thereby facilitating the reasonable arrangement of the construction load of the shaft sinking headframe and the improvement of the construction safety and reliability of the shaft sinking headframe, and accelerating the further development of the intelligence of shaft sinking equipment.

Description

technical field [0001] The invention relates to an intelligent shaft sinking derrick. Background technique [0002] Shaft sinking derrick is a steel structure for lifting and suspending excavation equipment during shaft shaft construction. In recent years, with the increase of the diameter and depth of wellbore in my country and the rapid development of mechanization of drilling, the use of drilling equipment such as large umbrella drills and large-capacity buckets has continuously increased the working load of drilling derricks, and the load forms are complex and have Uncertainty, if the load arrangement is unbalanced, it will easily lead to safety accidents. In order to ensure that the sinking derrick can safely bear the construction load, it is necessary to develop an intelligent shaft sinking derrick, which can monitor the stress state of the derrick in real time, and give an early warning when the construction load approaches the design bearing capacity of the derrick, ...
