Abstract
The utility model discloses a kind of device of fastening loosening large-sized bolt, supporting surface is there is around this large-sized bolt, this device comprises drawing body, drawing crossbeam, cushion block, two hydraulic jack, two hydraulic jack with large-sized bolt diameter for the axisymmetric placement of symmetry on the support surface, support cushion block above hydraulic jack push rod, support drawing crossbeam on cushion block, drawing crossbeam is connected in cross with drawing body; Drawing body is column, and one end of post is provided with to be provided with the internal thread hole of required fastening bolt adaptation, the other end to be convenient to screw structure; The oil pipe of two hydraulic jack is connected to same hydraulic pump.This device is compared with original Special tightening tool, has small investment, easy to operate, reaches the effect same of specific purpose tool; Compared with method is fastening with factories and miness tradition (hammering blow that shakes as adopted is fastening), there is all fastening torque of bolt consistent, easy and simple to handle, to save time, laborsaving, the advantages such as fastening rear life cycle is long.
Description
Technical field
The utility model belongs to the maintenance field of bolted machinery, relates to being applicable to all kinds of working condition and shaking large mechanical bolt and other has the fastener of the loose bolts of pad conditioning apparatus.
Background technology
Reductor is the key equipment of all kinds of manufacturing enterprise, and cylinder as used in board rolling production line cuts reductor, milling train distributor box etc.In process of production, very large because shearing, shaking in Biting Course, if bolt is not undertaken fastening by the pretightning force of standard completely, or bolt pretightening is lost because of long-term vibration, can cause cover bolt can be completely loosening in a short period of time.The bolt loosened needs to use Special bolt tightener, but the specific purpose tool of fastening relatively large bolt is expensive, and general enterprise can not prepare.
After the bolt looseness of reductor or miscellaneous equipment, bearing in reduction gears can be caused aborning to damage, and gear is beaten tooth and is fractureed, and lubricating oil leaks, and to equipment faults such as other parts impacts.Adopt the utility model method can solve bolt looseness easily and be difficult to a fastening difficult problem.
Utility model content
The utility model object is to provide the device of fastening relatively large bolt of simple and feasible, small investment.
The technical solution of the utility model: a kind of device of fastening loosening large-sized bolt, supporting surface is there is around this large-sized bolt, this device comprises drawing body, drawing crossbeam, cushion block, two hydraulic jack, two hydraulic jack with large-sized bolt diameter for the axisymmetric placement of symmetry on the support surface, support cushion block above hydraulic jack push rod, support drawing crossbeam on cushion block, drawing crossbeam is connected in cross with drawing body; Drawing body is column, and one end of post is provided with to be provided with the internal thread hole of required fastening bolt adaptation, the other end to be convenient to screw structure; The oil pipe of two hydraulic jack is connected to same hydraulic pump.
Drawing crossbeam is connected for being fixedly connected with drawing body, also can be and removably connects, and drawing body has through hole, and drawing crossbeam is through through hole.
The word or cross-shaped groove structure that structure is prism structure or top is convenient to screw in drawing body one end.
The utility model beneficial effect: the utility model is compared with original Special tightening tool, has small investment, easy to operate, reaches the effect same of specific purpose tool; Compared with method is fastening with factories and miness tradition (hammering blow that shakes as adopted is fastening), there is all fastening torque of bolt consistent, easy and simple to handle, to save time, laborsaving, the advantages such as fastening rear life cycle is long.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic side view of Fig. 1;
In figure, 1-drawing body, 2-drawing crossbeam, 3-cushion block, 4-hydraulic jack, 5-oil pipe, 6-hydraulic pump, 7-through hole.
concrete embodiment
As figure, a kind of device of fastening loosening large-sized bolt, supporting surface is there is around this large-sized bolt, this device comprises drawing body 1, drawing crossbeam 2, cushion block 3(select the carrying out of thickness or the different-thickness be applicable to combine according to actual needs), two hydraulic jack 4, two hydraulic jack 4 with large-sized bolt diameter for the axisymmetric placement of symmetry on the support surface, support cushion block 3 above hydraulic jack 4 push rod, support drawing crossbeam 2 on cushion block 3, drawing crossbeam 2 is connected in cross with drawing body 1; Drawing body 1 is column, and one end of post is provided with to be provided with the internal thread hole of required fastening bolt adaptation, the other end to be convenient to screw structure; The oil pipe 5 of two hydraulic jack 4 is connected to same hydraulic pump 6(and ensures that both sides lifting force is equal).Drawing crossbeam 2 is connected for being fixedly connected with drawing body 1; Also can be and removably connect, drawing body 1 has through hole, drawing crossbeam 2 is through through hole.Drawing body 1 one end is convenient to screw that structure is convenient wants fastening bolt top reserve on screw thread drawing body 1 precession, concrete structure can be a word or the cross-shaped groove structure at prism structure or top, entangles prism twist or insert a word or cross recess rotation with the pillar of one end band plate body with spanner.
During use, fastening bolt 7 top is wanted to reserve on screw thread drawing body 1 precession, when drawing crossbeam 2 is detachable mechanism, drawing crossbeam 2 is passed through hole, the drawing crossbeam 2 part both sides size that leaks outside is equal, and drawing crossbeam places cushion block 3, hydraulic jack 4 for 2 times successively, and primer fluid press pump 6 gives two hydraulic jack 4 fuel feeding simultaneously, hydraulic jack 4 synchronously raises, fastening bolt obtains carrying, and reaches pressurize after predictable pressure, then is screwed by nut 8 with hexagon 9; 6th step: hydraulic jack 4 pressure release, removes drawing crossbeam 2, cushion block 3, jack and drawing body 1, and what complete bolt is fastening.
