Abstract
The utility model be specially it is a kind of be used for the repeatable lever removal tool using expansion bolt, solving the problems, such as to exist when existing expansion bolt is removed wastes time and energy and easy damaged expansion tube leads to not recycling.Including pry handle, support pier and fixture, pry handle is integrally made up of tilting section pole and horizontal segment pole, and the upper end of the infall and support pier of tilting section pole and horizontal segment pole is hinged, the left end of horizontal segment pole is provided with ripping bar axle, fixture includes two be hinged clamping bars in middle part, the upper end of two clamping bars is provided with steel wire rope node, the lower end of two clamping bars is provided with horizontal brace rod, grip block is provided with the inside of two horizontal brace rods, ripping bar axle and two steel wire rope nodes are circumscribed with the steel wire rope of closing.Utility model works intensity is smaller, easy to carry, and the expansion tube integrity degree after extraction is higher, is easy to reuse.
Description
Technical field
Clamping removal tool is the utility model is related to, it is specially a kind of to be torn open for repeatable using the lever of expansion bolt
Except instrument.
Background technology
Expansion bolt is a kind of anchor for the installation that can be drilled on existing building.During installation, expansion bolt is put
Enter in the drilling of existing building, screw rod is pulled out by tightening nut, the iron sheet pipe with cut ends is passively outwards opened
Open so that screw rod conehead applies the normal pressure perpendicular to hole wall to conduit peschel, so as to produce certain withdrawal resistance, reaches anchoring mesh
's.
It is deep to be welcome by engineering circles because expansion bolt is cheap, install convenient.But undeniable to be, existing expansion
Bolt, which exists, removes the problem of difficult so that exposed shank of bolt, which is not easy to be blocked, covering and easily to get rusty, influence it is attractive in appearance, even if by force
Row is pulled out and can not also reused.
Technical staff has invented a kind of repeatable expansion bolt utilized simple in construction, including spiral shell by repeatedly practising
Bar 11 and expansion tube 12, the left part of screw rod 11 are provided with nut 13, and the right-hand member of screw rod 11 is provided with taper boss 14, expansion tube
12 left end is provided with pad I15, and the lateral wall of expansion tube 12 is provided with pad II16, and pad I15 external diameter is more than pad II16
External diameter, the right part side wall of expansion tube 12 is provided with bar-shaped trough 17, spring washer 18 is provided between nut 13 and pad I15.
When need remove when, first by nut 13 unscrew and be screwed to it is concordant with the top of screw rod 11, utilize hand hammer touch screw rod
11 heads, force one end of taper boss 14 to be exited from expansion tube 12, now, nut 13 is backed out from screw rod 11；Utilize
The tool cards such as crowbar, screwdriver firmly pull up upwards at the step that pad I15 and pad II16 is formed, can be by expansion tube 12
Extracted in from mounting hole 19.The opening of the lower end of expansion tube 12 is inwardly repaired eventually through instruments such as hand vice, hand hammers, in case
Reuse.
But during using instruments such as crowbar, screwdrivers, expansion tube 12 is pulled out by force, due to the individual of operating personnel
Difference causes the discontinuity of expansion tube 12, the outer wall of expansion tube 12 easily occurs and is damaged, and increase reparation difficulty, which even results in, to be pulled out
Expansion bolt can not be continuing with.
The content of the invention
The utility model is wasted time and energy and easy damaged expansion tube causes nothing to solve to exist when existing expansion bolt is removed
The problem of method reuses, there is provided a kind of to be used for the repeatable lever removal tool using expansion bolt.
The utility model is achieved by the following technical solution：It is a kind of to be used for the repeatable lever using expansion bolt
Removal tool, including pry handle, support pier and fixture, pry handle are integrally made up of tilting section pole and horizontal segment pole, and are tilted
Section pole and the infall of horizontal segment pole and the upper end of support pier are hinged, and the left end of horizontal segment pole is provided with front and rear distribution
Ripping bar axle, fixture includes two be hinged clamping bars in middle part, and the upper end of two clamping bars is provided with steel wire rope node, two clamping bars
Lower end be provided with horizontal brace rod to its inner side extension, be provided with grip block on the inside of two horizontal brace rods, prize
Bar axle and two steel wire rope nodes are circumscribed with the steel wire rope of closing.
When carrying out dismounting operation, grip block is inserted in the gap that pad I and pad II is formed, pull down pry handle, prized
The horizontal segment pole of handle is rotated clockwise using the pin joint of support pier as axle, so drive steel wire rope pull fixture two clamping bars to
Clamping is withdrawn in inner side；Continue to pull down pry handle, under the flexible effect of steel wire rope, a upward drawing is applied to expansion tube
Power, most it is extracted out of mounting hole at last, and overcoming when existing expansion bolt is removed to exist wastes time and energy and easy damaged expansion tube
The problem of leading to not recycling.
The inner of two grip blocks is provided with vertically arranged semicolumn groove.The semicolumn groove of clamping block causes repeatable using swollen
Swollen bolt uniform stressed, it is indeformable in withdrawal process to be effectively protected expansion tube.
The utility model is simple in construction, reasonable in design, and working strength is smaller, easy to carry, and dismountable grip block
The expansion bolt for being suitable for various sizes is removed, while is realized recycling, is saved great amount of cost, while the peace after pulling out
It is more complete to fill hole, is easy to the later stage to block.
