Specific embodiment
The supporting apparatus for being used to substitute bridge pad as shown in Figures 1 to 7, including U-shaped seat body 1, and and U-shaped seat
The sliding wedge 2 and lifting voussoir 3 that body 1 is slidably connected, and the screw rod 4 being fixedly connected with sliding wedge 2, and be removably mounted to
Punching jack 8 and sleeve 9 on screw rod 4, and the swivel nut 10 on the outside of sleeve 9 is installed on by screw thread；The sliding wedge 2
It is flexibly connected between U-shaped seat body 1 and lifting voussoir 3, and respectively with U-shaped seat body 1 and lifting voussoir 3；The screw rod 4 is through peace
Loaded in its centre bore of sliding wedge 2, and pass through left end nut 5 and intermediate nut 6 and the sealed fixation of sliding wedge 2 respectively；Institute
Stating screw rod 4, it passes through U-shaped seat body 1 away from 5 one end of left end nut and extends outwardly equipped with extension；Described its extension of screw rod 4
On right end nut 7 is installed；The punching jack 8 and sleeve 9 are successively sheathed on its extension of screw rod 4, and its right side of sleeve 9
Sidespin closes right end nut 7.
Described 2 upper part of sliding wedge is provided with obliquity prominence platform 13；Described 3 its underpart of lifting voussoir is provided with inclined groove
14；The sliding wedge 2 forms guiding with the inclined groove 14 for going up and down voussoir 3 by obliquity prominence platform 13 and is slidably connected.
Be formed with the oblique mechanism with latching characteristics between the sliding wedge 2 and lifting voussoir 3, and oblique mechanism its
Bevel angle is less than angle of friction.
Described 2 its underpart of sliding wedge is provided with horizontal groove 16；Described its bottom surface of U-shaped seat body 1 is provided with horizontal ledge
16；The sliding wedge 2 forms guiding by the horizontal ledge 16 of horizontal groove 16 and U-shaped seat body 1 and is slidably connected.
Its left and right sides forms being slidably connected for vertically-guided with lifting voussoir 3 on the inside of described its both side plate of U-shaped seat body 1.
Two pull rod studs 11 are fixed on described its right side plate of U-shaped seat body 1；Two pull rod studs 11 its deviate from U-shaped seat
1 side of body is fixed with counter-force seat 12 by fastening nut；When disassembly, its cylinder barrel end of the punching jack 8 is placed in counter-force seat
In 12 its pedestal groove 17.
Screw thread is installed on the right side plate of U-shaped seat body 1 two pull rod studs 11 respectively, and passes through nut lock with right side plate
It closes and fixes.
Its periphery of the sleeve 9 is equipped with external screw thread, and is threadedly coupled with the internal screw thread being equipped with inside swivel nut 10.
Its piston rod outer diameter of the punching jack 8 is less than 10 internal diameter of swivel nut.
The punching jack 8 is connected with electric hydraulic pump or hand oil pump.
The supporting apparatus for being used to substitute bridge pad of the utility model, due between sliding wedge and lifting voussoir
Form the oblique mechanism with latching characteristics, the obliquity prominence platform of sliding wedge top setting and the inclination of lifting lower wedge portion setting
Groove forms guiding and is slidably connected；The horizontal groove of sliding wedge lower part setting and the horizontal ledge shape of U-shaped seat body bottom surface setting
It is slidably connected at guiding；Screw rod is locked by left end nut, intermediate nut and sliding wedge；Punching jack, sleeve according to
It is secondary to be placed on screw rod right part, it is the right end nut for being combined on screw rod on the right side of sleeve；Before sliding wedge rises, first by auxiliary hydraulic pressure
Jack jacking and pushing bridge rises little height, and the piston rod of punching jack pushes sleeve later, and sleeve pushes right end nut, right
End nut drives screw rod to move to right, and screw rod drives sliding wedge to move to right, and sliding wedge, which drives to rise, moves to bridge bottom surface on sliding block, revolves
Turn swivel nut and move to left along sleeve to swivel nut left side and the cylinder barrel right side of punching jack to hold out against, it is very heavy to remove auxiliary hydraulic pressure later
Top, bridge load are born by rising voussoir, are less than angle of friction due to rising the tilt angle that voussoir and sliding wedge are slidably connected,
With self-locking function, sliding wedge, which will not move to left, to move to left in bridge load, to form firm support device；If rising
Voussoir and sliding wedge latching characteristics fail, sliding since the cylinder barrel of punching jack, swivel nut, sleeve, right end nut are successively held out against
Dynamic voussoir will not still move to left, and the hydraulic oil in the cylinder barrel of punching jack does not carry, and it is reliable for being formed by temporary support still
Support；
After new support firmly installs, when dismantling the supporting apparatus for being used to substitute bridge pad of the utility model,
Rise little height using the very heavy jacking and pushing bridge of jacking again of auxiliary hydraulic pressure, supporting apparatus is not subjected to heavy duty, tears open at this time
Lower right end nut, sleeve, swivel nut and punching jack, then right end nut is combined on to the appropriate location of its extension of screw rod, it adjusts
Turn punching jack direction, so that the tailpiece of the piston rod of punching jack is located at the right side of right end nut, be through on screw rod, then by 2
A pull rod stud is connected through a screw thread the right side plate that U-shaped seat body is fixed on nut check, then counter-force seat is installed on 2 pull rods
The right end of stud, and fixed by 4 fastening nuts, when punching jack is passed through hydraulic oil, the counter-force of counter-force seat is by wearing
The piston rod of heart jack acts on right end nut, pushes sliding wedge to move to left by screw rod, rises voussoir under the effect of gravity
Under be moved away from bridge bottom surface, then carry out subsequent disassembly；In addition, the temporary support for being used to substitute bridge pad of the utility model
Device can also can realize multiple be used in conjunction with by simply connecting with used aloned.
Above-described embodiment is only the better embodiment of the utility model, therefore all according to the utility model patent application range
The equivalent change or modification that the structure, feature and principle is done, is included in the scope of the utility model patent application.
