Novel mine anchor rod quality detection pulling device

Abstract

The invention discloses a novel mine anchor rod quality detection pulling device, and belongs to the technical field of mine anchor rod detection. The pulling device comprises an oil cylinder, a rear baffle plate, a pull rod, a clamping groove, a pulling vertical pillar, fixed vertical pillars, a front baffle plate, an anchor rod tray and an anchor rod; the pulling device is characterized in that the pull rod is fixedly inserted in the circle center of the surface of the rear top end of the oil cylinder; the pulling vertical pillar is fixedly connected on the surface of the rear top end of the pull rod; the clamping groove is formed in the edge of the back side of the surface of the side top end of the pulling vertical pillar; the anchor rod is inserted inside the clamping groove; the anchor rod tray is fixedly inserted in the surface of the side top end of the anchor rod; the rear baffle plate is inserted in the surface of the side top end of the pull rod; the plurality of fixed vertical pillars are evenly distributed on the edges around the surface of the rear top end of the rear baffle plate; and the front baffle plate is fixedly connected to the surfaces of the rear top ends of the fixed vertical pillars. The pulling device can relieve a phenomenon that a nut of the anchor rod falls off in the case that rod body or nut thread of the supporting anchor rod becomes damaged and can facilitate workers in detecting the tensile strength of the rod body and the bearing capacity of the tray of the supporting anchor rod in the field.

Description

Technical field: [0001] The invention belongs to the technical field of coal mine equipment, and in particular relates to a novel bolt quality detection and drawing device for coal mines. Background technique: [0002] In the long-term work practice, in the process of using anchor rods to reinforce the well wall in coal mines, it often happens that the anchor rod nuts fall off due to damage to the rod body or the nut thread of the supporting anchor rods, and the nuts fall off. The quality of the rod is fully and effectively tested. The corresponding testing agency can only test the tensile strength of the anchor rod body and the bearing capacity of the pallet. The thread bearing capacity of the tail of the rod body can only be sent to a professional testing agency in Beijing for monitoring. Invention content: [0003] The purpose of the present invention is: in order to solve the process of using anchor rods to reinforce the well wall in coal mines, it can reduce the pheno...

[0002] In the long-term work practice, in the process of using anchor rods to reinforce the well wall in coal mines, it often happens that the anchor rod nuts fall off due to damage to the rod body or the nut thread of the supporting anchor rods, and the nuts fall off. The quality of the rod is comprehensively and effectively tested. The corresponding testing agency can only test the tensile strength of the anchor rod body and the bearing capacity of the pallet. The thread bearing capacity of the tail of the rod body can only be sent to a professional testing agency in Beijing for monitoring.
