Abstract
The utility model relates to an anchor truss used for mining support, in particular to coal mine laneway support. The anchor truss is composed of anchor rods 1, a draw rod 2 and a connecting piece 3, wherein, the draw rod 2 is an integral frame; two ends of the draw rod and the connecting piece are respectively provided with straight cogs 7 and 8; the straight cogs 7 and 8 are mutually engaged after installation; the draw rod is abutted with a top board along full length. The middle part of the draw rod is provided with a transverse tension device, and a plurality of auxiliary anchor rods can be arranged between two anchor rods. The anchor truss has favorable supporting effect, good error adaptability for positioning anchor rod holes and easy installation.
Description
The utility model is a kind of mine laneway supporting anchor pole truss, is specially adapted to colliery development heading supporting.
The anchor pole truss generally is made up of inclination anchor pole, pull bar, connector and the strainer at two ends.Its operating principle is to provide anchored force by the inclination anchor pole, and top board is produced supporting role, and the top board load transfer to two in the span length scope is helped on the coal body.Connector couples together anchor pole and pull bar, and the anchored force of anchor pole is passed to roof strata.Strainer makes the pull bar tensioning, and roof strata is produced squeezing action.
The weak point of existing anchor pole truss is:
1. can not fit along total length between pull bar and the rock top board, influence supporting effect.
2. to the bad adaptability of bolthole position error.
3. inconvenience is installed.
The purpose of this utility model is to overcome the weak point of above-mentioned prior art, provides a kind of pull bar and top board to fit along total length, and is easy to operate, the anchor pole truss good to bolthole position error compliance.
The purpose of this utility model can reach by following measure:
Pull bar is taked whole closed-in construction; On pull bar both ends and the connector straight-tooth is arranged; Rear connectors is installed is meshed with the straight-tooth of pull bar, pull bar is fitted along total length and top board.
Can increase strainer at the middle part of pull bar and make the further tensioning of pull bar.
Accompanying drawing 1 is an embodiment of the present utility model.
Accompanying drawing 2 is the embodiment with auxiliary anchor pole.
The utility model is described in further detail below in conjunction with accompanying drawing:
Among Fig. 1, the 1st, anchor pole, the 2nd, pull bar, the 3rd, connector, the 4th, tensioning bolt.Pull bar 2 is by two main muscle 5 and the some general frames that horizontal bar 6 is welded.Be processed with straight-tooth 7 at the two ends of main muscle 5.The straight-tooth 8 that is meshed with straight-tooth 7 is arranged on connector 3.Tensioning bolt 4 transverse weld are at the pull bar middle part.
During installation two anchor poles 1 are inserted in the bolthole of top board, regulate the position of connector 3, find the nut of tightening behind the suitable position on the anchor pole 1 along the pull bar length direction.Straight-tooth engagement on connector and the pull bar at this moment, nut will connect and pull bar is pressed on the top board.Connector not only plays the effect that connects and compress pull bar, can also utilize the straight-tooth on it that pull bar is produced certain axial tension.Tighten tensioning bolt 4 and make the further tensioning of pull bar.
When the anchor pole truss span is big, can set up some auxiliary anchor poles along the pull bar length direction.Set up two auxiliary anchor poles 9 among Fig. 2, the nut of auxiliary anchor pole is pressed on supporting plate 10 on the pull bar.
The utility model compared with prior art has the following advantages:
1. pull bar is fitted along total length and top board, has improved supporting effect.
Connector along the pull bar lengthwise location can regulate and adjustable range big, therefore good to the adaptability of bolthole position error.
3. easy for installation.
4. tensioning bolt makes two main muscle synchronous tensions of pull bar, and is evenly stressed.
