Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, the present embodiment is with this utility model
Implemented under premised on technical scheme it should be understood that these embodiments are merely to illustrate this utility model rather than limit this reality
With new scope.
As shown in figure 1, a kind of hydraulic spreader in large displacement expansion joint gap, hinged including jointed shaft 1 and its two ends
Sleeve 2；The middle part of described jointed shaft 1 is radially provided with movable floor 3 to side；And the hinged sleeve 2 at two ends radially to
Opposite side is provided with holistic fixing base plate 4；The middle part of jointed shaft 1 is radially additionally provided with activity strength plate 5, this activity strength plate
5 is 100 ° -140 ° with the angle of movable floor 3；And the end of described movable floor 3 is also equipped with and activity strength plate 5 position
Relative hydraulic press baffle plate 6.
The hinged sleeve 2 at described two ends is each provided with one block of fixing strength plate 7 along same radial direction；Two blocks of fixing strength plates 7
It is on same straight line, the angle with fixing base plate 4 is 100 ° -140 °；And the end of described fixing base plate 4 is provided with and solid
Determine the relative hydraulic press baffle plate 6 in strength plate 7 position.
Movable floor 3 and fixing base plate 4 is made to produce relative dislocation by hydraulic jack when this utility model uses
Rotate, drive fixing strength plate 7 and activity strength plate 5 mutual dislocation by the gap expansion adjustment at expansion joint, therefore should be appropriately arranged with
Angle between activity strength plate 5 and movable floor 3 and fixing base plate 4 and fixing strength plate 7, is arranged by practical operation, works as work
When the angle of the angle between dynamic strength plate 5 and movable floor 3 and fixing strength plate 7 and fixing base plate 4 is 120 °, activity strength plate 5 He
Expansion joint preferably, can be expanded and come by the effect of the expansion between fixing strength plate 7 well.
As shown in Figure 2 and Figure 5, the length of activity strength plate 5 and two blocks of fixing strength plates 7 is identical, and in activity strength
Plate 5 and fixing strength plate 7 are to may be on same straight line when rotation；Fixing strength plate 7 and activity strength plate 5 are set to same
When on straight line, fixing strength plate 7 and activity strength plate 5 are placed in the gap at expansion joint, and hydraulic jack is placed on the liquid of both sides
In depressor baffle plate；As shown in Figure 3, after shake hydraulic jack, movable floor 3 and fixing base plate 4 are extruded to both sides, so
Fixing strength plate 7 and activity strength plate 5 will stagger to both sides, thus extruding expansion joint, so that gap is expanded and coming, such that it is able to hold very much
Easily adjust the gap at expansion joint.
As shown in figure 4, the width of fixing base plate 4 and movable floor 3 can be arranged according to practical situation, practical for convenience
Can to arrange fixing base plate 4 identical with the width of movable floor 3 with placing hydraulic jack, and places fixing bottom for convenience
Plate 4 and enable movable floor 3 flexibly to rotate, the length of movable floor 3 is set to 1/3rd of fixing base plate 4.
When actually used, if hydraulic jack drops accidentally, peace can be produced to the people of shake hydraulic jack
Full hidden danger, therefore injures others by a crashing object to prevent hydraulic jack from can accidentally drop, in the end of movable floor 3 and fixing base plate 4
It is additionally provided with the safety screen 8 relative with activity strength plate 5 and fixing strength plate 7 position；Safety screen 8 sets up, activity
Strength plate 5 and fixing strength plate 7 are down-set, and both are oppositely arranged.After so hydraulic jack being placed by a people, shake
The gap expansion at expansion joint just can be come by jack.
The pressure of hydraulic jack is larger, in order to increase the soundness of safety and hydraulic press baffle plate, this safety screen 8
Bottom be additionally provided with oblique reinforcement 9, described oblique reinforcement 9 supports corresponding hydraulic press baffle plate 6；Added by oblique
Strong muscle 9 increases the soundness of hydraulic press.
When actually used, if fixing strength plate 7 and activity strength plate 5 are all put into inside expansion joint, its expansion
The effect of adjustment is poor, because the expansion scope of the root of fixing strength plate 7 and activity strength plate 5 is very little, and head
Expansion scope be maximum, therefore the lower surface in movable floor 3 and fixing base plate 4 also sets up limiting plate 10；Movable floor 3
On limiting plate 10 extend for connection to be integrally formed formula structure on activity strength plate 5；Limiting plate 10 on fixing base plate 4 extends connection
It is integrally formed formula structure on fixing strength plate 7；The height of described limiting plate 10 is set to the two of activity strength plate 5 and fixing strength plate 7
/ mono-.
Limiting plate 10 does not interfere with the relatively rotating, because both limiting plates 10 are phases of fixing strength plate 7 and activity strength plate 5
Mutually interlock, limiting plate 10 limits the depth that fixing strength plate 7 and activity strength plate 5 are placed in clearance of expansion rail, makes fixing strength plate 7
Suitable with the head of activity strength plate 5 puts in clearance of expansion rail such that it is able to farthest expand the gap at expansion joint
Come, the height of limiting plate 10 is difficult too high, it is preferably provided as 1/2nd of activity strength plate 5 and fixing strength plate 7, so fixing
Strength plate 7 and activity strength plate 5 can be suitable put in the adjustment carrying out maximum efficiency in the gap at expansion joint, therefore Adjustment effect is
Best.
In sum, the hydraulic spreader of large displacement expansion joint of the present utility model, it is rational in infrastructure, easy to use, adjusts
Whole effect is good, easy to use, and safety coefficient is high, can a people just can be very good to use.
The above is only preferred implementation of the present utility model it is noted that common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
