Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, being further elucidated with the present invention, the present embodiment is with technical solution of the present invention
Implement under premised on, it should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention.
As it is shown in figure 1, the hydraulic spreader in a kind of 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, is 100 °-140 ° with the angle of fixing base plate 4；And the end of described fixing base plate 4 is provided with solid
Determine the hydraulic press baffle plate 6 that strength plate 7 position is relative.
Make movable floor 3 and fixing base plate 4 produce relative dislocation by hydraulic jack when that the present invention using to rotate,
Drive fixing strength plate 7 and activity strength plate 5 mutual dislocation to be expanded in the gap at expansion joint to adjust, therefore should be appropriately arranged with activity strength
Angle between plate 5 and movable floor 3 and fixing base plate 4 and fixing strength plate 7, is arranged by practical operation, when activity strength plate 5
And when the angle of angle between movable floor 3 and fixing strength plate 7 and fixing base plate 4 is 120 °, activity strength plate 5 and fixing strength plate
The effect of the expansion between 7 is best, it is possible to is well expanded at expansion joint and comes.
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 of rotation；Fixing strength plate 7 and activity strength plate 5 are set to same
Time 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 extrude expansion joint, make gap expansion come, 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
Fixing base plate 4 can be set with placement hydraulic jack identical with the width of movable floor 3, and place the fixing end for convenience
Plate 4 and make movable floor 3 to rotate flexibly, the length of movable floor 3 is set to 1/3rd of fixing base plate 4.
Actually used when, if hydraulic jack drops accidentally, the people of shake hydraulic jack can be produced peace
Full hidden danger, therefore to prevent hydraulic jack from can accidentally drop injure others by a crashing object, in movable floor 3 and the end of 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, movable
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 at expansion joint just can be expanded and come by jack.
The pressure of hydraulic jack is relatively big, in order to increase safety and the soundness of hydraulic press baffle plate, and this safety screen 8
Bottom be additionally provided with oblique reinforcement 9, described oblique reinforcement 9 support correspondence hydraulic press baffle plate 6；Added by oblique
Strong muscle 9 increases the soundness of hydraulic press.
Actually used when, if fixing strength plate 7 and activity strength plate 5 are all put into inside expansion joint, its expansion
The effect adjusted is poor, because the expansion scope of the root of fixing strength plate 7 and activity strength plate 5 is the least, and head
Expansion scope be maximum, therefore the lower surface at 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 activity strength plate 5 and the two of fixing strength plate 7
/ mono-.
Limiting plate 10 does not interferes with the relatively rotating, because both limiting plates 10 are phases of fixing strength plate 7 and activity strength plate 5
Interlock mutually, the degree of depth that the fixing strength plate 7 of limiting plate 10 restriction and activity strength plate 5 are placed in clearance of expansion rail, make fixing strength plate 7
Suitable with the head of activity strength plate 5 put in clearance of expansion rail such that it is able to farthest the gap at expansion joint is expanded
Coming, the height of limiting plate 10 is difficult to too high, it is preferably provided as activity strength plate 5 and 1/2nd of fixing strength plate 7, the most fixing
Carrying out the adjustment of maximum efficiency in the gap putting in expansion joint that strength plate 7 and activity strength plate 5 can be suitable, therefore Adjustment effect is
Best.
In sum, the hydraulic spreader of the large displacement expansion joint of the present invention, it is rational in infrastructure, easy to use, adjusts effect
The best, easy to use, safety coefficient is high, can a people just can well use.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
