Abstract
The utility model discloses a pre-tightening installing device for anchor rods, which is composed of a stretched jack 1, an oil pump 2, an oil pipe 3, a sheathed type top press head 4 and an electric coal drill 5. Because the top press head of the pre-tightening installing device for anchor rods uses the sheathed type so that the top head is caused to have the advantages of compact structure, reasonable structure and small size, [and] thus, the exposed part of an anchor rod or an anchor cable is reduced; at the same time, because the electric coal drill is directly used by dynamic force, a pull wire in a drift is reduced. The utility model can be used for installing pre-stress anchor rods or pre-stress anchor cables.
Description
The utility model relates to and gives stress anchor pole erecting device, and specifically a kind of anchor pole gives tight erector, is applicable to that the stress anchor pole that gives in coal mining or the tunnelling is installed.
In the driving in the exploitation in colliery or tunnel, the rock stratum is adopted bolt support or cable bolting mostly, stress is given in also having applied of having, and claims to give the stress anchor pole or give the stress anchor cable.Use at present give the stress anchor pole or anchor cable is made of the body of rod, anchor slab, key, need use special-purpose erecting tools when skyhook or anchor cable, it is applied give stress, this instrument comprises stretch-draw jack, oil pump, oil pipe, motor special and stacked roof pressure head, this stacked roof pressure head is owing to wedge top, spring, overlapping being installed in of platen are coiled in the top, so structure is not compact, volume is big, use inconvenient, and after the anchor pole installation, the anchor pole exposed portions serve is bigger, and stream takes material, reduces the tunnel useful area.Simultaneously, because of motor is special-purpose, range of application is narrower, and in addition, in work progress, perforating is given the stress anchor pole with pump and installation and all needed independent backguy with pump, is unfavorable for construction.
The purpose of this utility model is to provide a kind of compact conformation, volume is little, application is convenient, the anchor pole of economical with materials, available electric coal drill driven by motor gives tight erector.
The utility model is achieved in that this anchor pole gives tight erector and is made of stretch-draw jack, oil pump, oil pipe, and the front end of its stretch-draw jack and sleeve type roof pressure head are connected and fixed, and oil pump is connected transmission with electric coal drill.Sleeve type roof pressure head is by Pan Ding, the wedge top, spring, platen constitutes, the wedge top, spring, platen is sleeved in the dish top successively, spring is contained in the wedge top, the wedge top is sleeved in the dish top, platen is rotated in the outside on wedge top, and be sleeved in the dish top, make structure more reasonable by suit, compactness has reduced the volume of roof pressure head, has dwindled the anchor pole exposed portions serve, oil pump is connected transmission with electric coal drill by connecting axle, one end of connecting axle and the turning cylinder of electric coal drill are connected and fixed, and the turning cylinder of the other end and oil pump is connected and fixed, and electric coal drill is general in perforating with when giving tight anchor pole, reduce backguy, helped operation.In addition, also can establish upper bearing (metal) and bracing frame, with the stability that keeps rotating at the connecting axle place.
The utility model is compared with the existing stress anchor pole erecting tools that gives, and its advantage is:
1, the roof pressure header structure is reasonable, compact, volume is little, application is convenient.
2, electric coal drill is general, has reduced backguy, helps producing.
3, the anchor pole exposed portions serve is little, has reduced consumptive material, has increased the tunnel useful area.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 looks schematic diagram for the utility model master.
Fig. 2 is the utility model sleeve type roof pressure head cross-sectional schematic.
Make the utility model with reference to accompanying drawing 1,2.This anchor pole gives tight erector, is made of stretch-draw jack 1, oil pump 2, oil pipe 3, and the front end of stretch-draw jack 1 and sleeve type roof pressure head 4 are connected and fixed, and oil pump 2 is connected transmission with electric coal drill 5.Sleeve type roof pressure head 4 is made of dish top 6, wedge top 7, spring 8, platen 9, and wedge top 7, spring 8, platen 9 are sleeved in the dish top 6 successively, and spring 8 is contained in the wedge top 7, and wedge top 7 is sleeved in the dish top 6, and platen 9 is rotated in the outside on wedge top 7, and is sleeved in the dish top 6; Oil pump 2 is connected transmission with electric coal drill 5 by connecting axle 10, and an end of connecting axle 10 and the turning cylinder of electric coal drill 5 are connected and fixed, and the turning cylinder of the other end and oil pump 2 is connected and fixed.The outer end of connecting axle 10 also is provided with bearing and bracing frame, with the stability that keeps rotating.When using the utility model, to coil top 6 is pressed on the anchor slab, wedge top 7 is pressed on the fixedly key of anchor pole, anchor pole or anchor cable pass the center cavity on wedge top 7, be stuck on the locking device in the stretch-draw jack 1, open electric coal drill 5, drive oil pump 2 work, 1 work of stretch-draw jack, outer on the one hand anchor pole or the anchor cable of drawing, promotion dish top 6 compresses anchor slab on the one hand, and simultaneously, wedge top 7 effects by spring 8 compress key, anchor pole or anchor cable are given tightly, when electric coal drill quit work, because the effect of key, anchor pole or anchor cable can not bounce back because of locking.
