Abstract
The utility model relates to a kind of porous anchor anchor cable intermediate plate anchor restorer, and this anchor restorer comprises: the peep hole (2) that punching cylinder (1), punching cylinder barrel are reserved and be welded in the block (3) of punching cylinder inner wall.Using the utility model to match with jack can a removal multi beam anchor cable work clip sheet, and efficiency of construction is promoted largely.
Description
Technical field
The utility model relates to a population anchor and moves back anchor device, relates in particular to a kind of porous anchor anchor cable intermediate plate anchor restorer of the anchor cable of removal multi beam simultaneously work clip sheet.
Background technology
When anchor cable construction, because of steel strand, intermediate plate and the anchor slab situation that often there will be stripped thread or fracture of wire lack of standardization that do not match or construct, once occur that above situation need to discharge anchor cable prestressing force and use, move back anchor device and exit work clip sheet in ground tackle; In addition, during as the side slope of anchor cable reinforcing or foundation ditch generation excessive deformation, need to anchor cable pulling force, monitor by anchor dynamometer is installed, also need first to deactivate intermediate plate, after removing anchorage device, anchor dynamometer could be installed.
Existing anchor cable moves back in anchor technology, disclose several utility model prestress anchorage cables and moved back anchor device: utility model name has been called group anchor single hole and has moved back the windlass structure (patent No.: CN201020269269.7), this device can solve the anchor problem of moving back of single bundle anchor cable, but moves back anchor inapplicable for the multi beam anchor cable of porous anchor simultaneously.If adopt this device to move back one by one anchor, there will be by duration, inefficient problem, and along with the minimizing of work anchor cable quantity can cause ground tackle or backing plate because unbalance stress deforms or ftractures.Also have a kind of utility model patent name to be called the anchorage cable spreading apparatus (patent No.: CN02238425.1), this covering device is set up an intermediate plate between anchor work clip sheet and jack tool clamping piece, utilizes spring and piston to control the intermediate plate of setting up and solves the problem of jack stroke deficiency.But for the problem of jack stroke deficiency, before jack tool clamping piece is installed, apply oil pressure and jack piston is ejected to certain length can solve.This is the existing weak point of prior art.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of efficiency of construction high, the convenient and safe anchor device that moves back that is applicable to porous anchor multi beam anchor cable intermediate plate while removal, and make piston eject certain length by the mode of prior startup jack, to solve, to move back jack stroke in anchor oil return process not enough and cause the problem that jack tool clamping piece cannot removal.
Basic ideas of the present utility model are to place anchor restorer in the outside of ground tackle, and so-called anchor restorer is the punching cylinder with peep hole and block.Punching cylinder end is propped up to anchor plate, and make peep hole one end towards the orientation of being convenient to observe.Start jack tension anchor cable and move outward, jack rear punching cylinder internal stop props up work porous anchor, to guarantee keeping static in process that ground tackle moves at anchor cable outward.Meanwhile, work clip sheet moves with anchor cable is outer, and automatic trip drops in anchor restorer from ground tackle subsequently, realizes and moves back anchor.
After observing all working intermediate plate and coming off, by oil return, shrink jack piston.If piston stroke is not enough during jack oil return, can before installing, tool clamping piece eject in advance jack piston, and piston ejects the stretch-draw length of length anchor cable when moving back anchor.
Design scheme of the present utility model is: a kind of porous anchor anchor cable intermediate plate anchor restorer, is characterized in that this anchor restorer comprises: the peep hole 2 that punching cylinder 1, punching cylinder barrel are reserved and be welded in the block 3 of punching cylinder inner wall.Punching cylinder 1 is enclosed within ground tackle outside, its internal diameter conforms to group's anchor ground tackle external diameter, peep hole 2 numbers should be determined according to the anchor cable radical of group's anchor ground tackle, but should guarantee the requirement of strength of punching cylinder when moving back anchor stretch-draw, be welded in punching cylinder inner wall and apart from punching cylinder end distance, must not be less than group anchor ground tackle height for propping up group block of anchor ground tackle 43, block 3 should be avoided work clip sheet along the setting position of punching cylinder inner wall circumference, work clip sheet moves outward when not affecting stretch-draw, when block magnitude setting and weld strength should guarantee to move back anchor stretch-draw, by ground tackle, is not cut off.
Further scheme is: before tool clamping piece is installed, eject in advance jack piston, the problem of piston stroke deficiency when solving jack oil return.
Adopt the utility model to compare and there is following advantage with existing anchor restorer: using the utility model to match with jack can a removal multi beam anchor cable work clip sheet, and efficiency of construction is promoted largely.And because multi beam anchor cable work clip sheet exits simultaneously, ground tackle and backing plate are stressed has evenly reduced the two probability deforming, and has extended the application life of ground tackle and backing plate, has reduced cost; By ejecting in advance jack piston stroke, the problem that in the time of can solving jack oil return, the not enough tool clamping piece of piston stroke cannot removal need not installed by other when moving back anchor, and simple possible is easy to use.
accompanying drawing explanation:
This manual comprises 3 width accompanying drawings, and wherein Fig. 1 is anchor restorer axis projection schematic diagram, and Fig. 2 is the 1-1 sectional drawing shown in Fig. 1, and Fig. 3 is the 2-2 sectional drawing shown in Fig. 1.
the specific embodiment:
(1) while using anchor restorer, anchor restorer punching cylindrical sleeve is outside at ground tackle, along punching Cylindorical rod to perspective view as shown in Figure 1, this anchor restorer, by punching cylinder barrel 1, is arranged at the peep hole 2 of barrel and block 3 compositions of barrel inner side, in Fig. 1,4 is ground tackle, and 5 for intending removing work clip sheet;
(2) utilize jack tension anchor cable, there will be ground tackle with the outer phenomenon of moving of anchor cable, cause work clip sheet to be difficult to take out, in Fig. 1, block 3 can prevent that ground tackle from moving outward, and the position relationship of block 3 and ground tackle as depicted in figs. 1 and 2;
(3) jack is when stretch-draw anchor, because ground tackle is fixed by the block 3 in Fig. 1, filing appliance sector-meeting moves with anchor cable is outer, Automatic-falling is in anchor restorer punching cylinder, even if there is not obviously outer moving in work clip sheet, but because of work clip sheet, now do not born prestressing force, utilized the rod members such as screwdriver can peel off work clip sheet 5 through peep hole 2, the position relationship of peep hole and anchor slab as shown in figures 1 and 3;
(4) as erecting tools intermediate plate the jack piston return in the situation that, by above (1) to (3) step, work clip sheet can be uncaged, but because anchor cable itself has prestressing force, after the playback of oil return jack piston, there will be the locking of jack front end tool intermediate plate, jack tool clamping piece cannot removal situation, for preventing that tool clamping piece locking from can eject jack piston certain stroke before erecting tools intermediate plate.
Through engineering practice, show, this utility model can once exit all working intermediate plate of porous anchor, convenient to use.
