Description
Technical field:
The utility model belongs to technique with the apparatus field, colliery, is specifically related to a kind of New type coal mine anchor rod quality testing draw-off gear.
Background technology:
In long-term working practice, anchor pole is used to come in Reinforcing Shaft process at underground coal mine, frequent generation support anchor rod causes anchor nut obscission because the body of rod or nut thread damage, nut comes off, existing instrument and equipment is difficult to detect comprehensively and effectively anchor pole quality, corresponding testing agency can only detect anchor rod body tensile strength and pallet bearing capacity, and body of rod tailing screw flight bearing capacity can only be delivered to specialty testing agency of Pekinese and monitor.
Utility model content:
The purpose of this utility model is: use anchor pole to come in Reinforcing Shaft process to solve at underground coal mine, raw support anchor rod can be reduced and cause anchor nut obscission because the body of rod or nut thread damage, and can facilitate staff's Site Detection support anchor rod body of rod tensile strength and pallet bearing capacity, its technical scheme is as follows:
A kind of New type coal mine anchor rod quality testing draw-off gear, it comprises oil cylinder 1, backboard 2, pull bar 3, draw-in groove 4, draw column 5, vertical columns 6, front apron 7, anchor rod pallet board 8, anchor pole 9, it is characterized in that: after described oil cylinder 1, top end surface circle centre position is fixedly fitted with pull bar 3, after described pull bar 3, top end surface is fixedly connected with and draws column 5, described top end surface rearward edges place, column 5 side of drawing is provided with draw-in groove 4, described draw-in groove 4 inside is fitted with anchor pole 9, described anchor pole 9 side top end surface is fixedly fitted with anchor rod pallet board 8, described pull bar 3 side top end surface is fitted with backboard 2, after described backboard 2, top end surface edge average mark is furnished with several vertical columns 6, after described vertical columns 6, top end surface is fixedly connected with front apron 7, described pull bar 3 and top end surface front edge place, described anchor pole 9 side are provided with screw thread, and described thread flank surfaces is fitted with nut, nut described in the described front top of pull bar 3 is stuck in top end surface circle centre position before described oil cylinder 1, it is inner that nut described in the described front top of anchor pole 9 is stuck in described draw-in groove 4, top end surface middle, described oil cylinder 1 side is fixedly connected with pulling force display screen.And top end surface circle centre position is provided with through hole before described backboard 2, described through-hole diameter is less than described oil cylinder 1 diameter, and after the T-shaped shape of described draw-in groove 4 described draw-in groove 4, top is gap.
The beneficial effects of the utility model are: use anchor pole to come in Reinforcing Shaft process to solve at underground coal mine, raw support anchor rod can be reduced and cause anchor nut obscission because the body of rod or nut thread damage, and staff's Site Detection support anchor rod body of rod tensile strength and pallet bearing capacity can be facilitated.
Accompanying drawing illustrates:
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Embodiment:
With reference to a kind of New type coal mine anchor rod quality testing draw-off gear described in Fig. 1, it comprises oil cylinder 1, backboard 2, pull bar 3, draw-in groove 4, draw column 5, vertical columns 6, front apron 7, anchor rod pallet board 8, anchor pole 9, it is characterized in that: after described oil cylinder 1, top end surface circle centre position is fixedly fitted with pull bar 3, after described pull bar 3, top end surface is fixedly connected with and draws column 5, described top end surface rearward edges place, column 5 side of drawing is provided with draw-in groove 4, described draw-in groove 4 inside is fitted with anchor pole 9, described anchor pole 9 side top end surface is fixedly fitted with anchor rod pallet board 8, described pull bar 3 side top end surface is fitted with backboard 2, after described backboard 2, top end surface edge average mark is furnished with several vertical columns 6, after described vertical columns 6, top end surface is fixedly connected with front apron 7, described pull bar 3 and top end surface front edge place, described anchor pole 9 side are provided with screw thread, and described thread flank surfaces is fitted with nut, nut described in the described front top of pull bar 3 is stuck in top end surface circle centre position before described oil cylinder 1, it is inner that nut described in the described front top of anchor pole 9 is stuck in described draw-in groove 4, top end surface middle, described oil cylinder 1 side is fixedly connected with pulling force display screen.And top end surface circle centre position is provided with through hole before described backboard 2, described through-hole diameter is less than described oil cylinder 1 diameter, and after the T-shaped shape of described draw-in groove 4 described draw-in groove 4, top is gap.
