Multi-position anchor cable construction device

Abstract

The multi-position anchor cable construction device comprises a supporting bottom plate, a fixing shaft, a lifting frame and an anchor cable rack, the fixing shaft is installed at the top end of the supporting bottom plate through a bearing, a rotating disc is arranged at the top end of the fixing shaft, a transmission mechanism used for free rotation is arranged on the outer wall of the fixing shaft, and a lead screw is installed at the top end of the rotating disc through a bearing; guide rods are arranged at the two ends of the top end of the rotary disc, a lifting frame penetrating through the guide rods is arranged on the outer wall of the lead screw, the interior of the lifting frame is meshed with the outer wall of the lead screw, movable shafts are installed on the inner side of the lifting frame through bearings, and an anchor cable rack is arranged between the movable shafts. A limiting mechanism used for fixing the position of the anchor cable rack is arranged in the lifting frame. By the adoption of the technical scheme, the problems of construction shoulder nests of the anchor cable machine and the angle of the anchor cable on the side are solved, and the effective vertical anchoring depth of the anchor cable is increased.

Description

technical field [0001] The invention belongs to the field of mine protection devices, and more specifically, the invention relates to a multi-position anchor cable construction device. Background technique [0002] With the extension of mine mining, the roadway is buried deeper and deeper, the ground pressure increases accordingly, the mine pressure is obvious, and the roadway support level is enhanced. In the process of strengthening support, the anchor cables are often constructed at the side and shoulder sockets, but when using a bolter for construction, the angle of the shoulder sockets and the side anchor cables is not enough. When the anchor cables are pressurized to the design pre-tightening force, the anchor cables The tray is bent, the anchor cable is cut, the greater the deformation of the roadway, the greater the shear force, and eventually the anchor cable is cut, the anchor cable tray falls off, and the safety hazard is great. However, the existing problems are ...

Problems solved by technology

In the process of strengthening support, the anchor cables are often constructed at the side and shoulder sockets, but when using a bolter for construction, the angle of the shoulder sockets and the side anchor cables is not enough. When the anchor cables are pressurized to the design pre-tightening force, the anchor cables The tray is bent, the anchor cable is cut, the greater the deformation of the roadway, the greater the shear force, and eventually the anchor cable is cut, the anchor cable tray falls off, and the safety hazard is great. However, the existing problems are summarized as follows: 1. It is not easy to Adjust the angle of the anchor cable; 2. It is not convenient to adjust the eye position of the anchor cable through the hole height of the anchor cable, making it impossible to meet the diversified market demand
