Description
Technical field
The utility model relates to a kind of rapid dismounting type jack reaction rack equipment.Belong to engineering equipment field.
Background technology
At present in steel box-girder sliding construction process, general hoist engine and the jack of using is as draw-gear.Namely hoist engine draw-gear lays hoist engine in the termination of sliding rail, carries out horizontal drag to sliding element; When jack is as draw-gear, jack is arranged in below steel box-girder, relies on the reaction force of jack to drive steel box-girder to move forward.
But when using hoist engine as draw-gear, the traction power provided is limited, and slippage Stroke Control is comparatively loaded down with trivial details.When using jack thrusting slip, jack stroke is shorter, and needs removing and installing repeatedly, can not ensure the uniformity of slippage, consume more manpower and materials, greatly reduce sliding construction efficiency between multiple jack.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the jack reaction rack equipment that a kind of convenient disassembly, rapid operation, structure are simple, improve sliding construction efficiency is provided, can be widely used in the sliding construction process of large-tonnage steel box-girder or concrete prefabricated beam.
The purpose of this utility model is achieved in that a kind of quick distachable formula jack reaction rack equipment, it comprises base holddown groove, hollow jack, threaded rod and clamping device, be fixedly installed in the side of described bottom holddown groove and add powerful plate, the baffle plate powerful plate is provided with for stopping hollow jack bottom is added described, described hollow jack is fixed on base holddown groove by clamping device, push plate is had at the push rod end winding support of hollow jack, push plate is fixed with nut, described threaded rod is successively through push plate, hollow jack and baffle plate, and and nut check, described hollow jack is provided with oil-in and oil-out.
Described clamping device comprises the first holder, the second holder and grips seat, grip seat to be connected with base holddown groove by bolt, second holder is installed on and grips on seat, and the first holder and the second holder are arranged up and down, and the middle hollow jack that supplies passes.
Compared with prior art, the beneficial effects of the utility model are:
A kind of rapid dismounting type jack of the utility model reaction rack equipment, multiple jack reaction frame fastening devices controls by same oil circuit, can guarantee the displacement synchronous of sliding construction.Can be interconnected between multiple screw-thread steel, ensure that the continuity of sliding construction, connected by bolt or draw-in groove between each holder, structural safety, simple to operate, convenient disassembly, improve sliding construction efficiency significantly.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment.
Wherein:
Base holddown groove 1, add powerful plate 2, baffle plate 3, hollow jack 4, oil-in 5, first holder 6, second holder 7, grip seat 8, push plate 9, nut 10, threaded rod 11, oil-out 12.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of quick distachable formula jack reaction rack equipment, comprise base holddown groove 1, hollow jack 4, threaded rod 11 and clamping device, base holddown groove 1 is welded on sliding rail, be fixedly installed in the side of described bottom holddown groove 1 and add powerful plate 2, the baffle plate 3 powerful plate 2 is provided with for stopping hollow jack 4 bottom is added described, baffle plate 3 central aperture is close to and is added powerful plate 2 one end, described hollow jack 4 is fixed on base holddown groove 1 by clamping device, push plate 9 is had at the push rod end winding support of hollow jack 4, described push plate 9 is fixed with nut 10, described threaded rod 11 is successively through push plate 9, hollow jack 4 and baffle plate 3, and with nut 10 screw-threaded coupling, described hollow jack 4 is provided with oil-in 5 and oil-out 12, the push rod of hollow jack is made to promote push plate and nut from oil-in 5 input power oil, nut drives threaded rod one end to travel forward, thus form pulling force at the other end of threaded rod.
Described clamping device comprises the first holder 6, second holder 7 and grips seat 8, grip seat 8 to be connected with base holddown groove 1 by bolt, offer groove gripping on seat 8, second holder 7 is fixing with in groove, first holder 6 and the second holder about 7 are arranged, two ends are crossed bolt and are connected, and the middle hollow jack 4 that supplies passes.
Rapid dismounting type jack reaction rack equipment in use, first base holddown groove 1 is fixed on sliding rail, then the first holder 6 is opened, being placed on by hollow jack 4 in second holder 7 and being fixed, secondly screw-thread steel 13 is fixed on the termination of hollow jack 4 through hollow jack 4 by nut 12.Last multiple hollow jack 4 is controlled by same oil circuit, can realize corresponding sliding construction operation.
