Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment and Detailed description of the invention, the preferred embodiment that the present invention is further explained.
Embodiment
Fig. 1-Fig. 7 is please referred to, the present invention provides a kind of equipment for the construction of bridge bottom wall, and structure includes mounting seat
1, reinforcing bar 2, large arm 3, forearm 4, hydraulic stem 5, railing 6, central strut 7, Extension support 8, described 3 one end of large arm and mounting seat 1
Installation connection, 3 other end of large arm and 4 axis of forearm connect, and the forearm 4 is vertically installed with far from the terminal horizontal of large arm 3 to be prolonged
Frame 8 is stretched, hydraulic stem 5 is equipped at the switching of the Extension support 8 and forearm 4 and forearm 4 and large arm 3, the railing 6, which is set to, to be extended
8 two sides of frame, the Extension support 8 and railing 6 are vertically fixed, and the Extension support 8 is equipped with central strut 7 far from the end of forearm 4.
The central strut 7 is made of negative pressure cylinder 71, telescopic rod 72, fixation hole 73, pedestal 74, and the negative pressure cylinder 71 is located at
Right above telescopic rod 72, the telescopic rod 72 is fixedly connected with negative pressure cylinder 71, the bottom end of the telescopic rod 72 far from negative pressure cylinder 71
Fixed with pedestal 74,74 bottom of pedestal is hemispherical dome structure, and the position of 74 middle of pedestal is provided with a fixation hole
73, the central strut 7 is mainly movably fixed on Extension support 8 by fixation hole 73, since its bottom is hemispherical dome structure, In
In rotation process, rotation is smooth, and Caton does not occur.
The negative pressure cylinder 71 is made of outer cylinder b and piston rod c, and the bottom the outer cylinder b and telescopic rod 72 are threadedly coupled, described
Piston rod a c, the piston rod c and outer cylinder b are equipped with inside outer cylinder b using being slidably matched, set on the outer cylinder b there are two with
On the sliding mouth b1 of bar shaped, the sliding mouth b1 of these bar shapeds is evenly distributed, and the distance between sliding mouth b1 of twice bar shaped is equal.
The piston rod c is made of chock plug c1, strut c2, holding rod c3, inserting hole c4, chassis c5, and the chock plug c1 is located at
Inside outer cylinder b, the outer cylinder b interior diameter and chock plug c1 overall diameter are equivalent, and the middle the chock plug c1 is vertically equipped with a strut
The bottom end c2, the strut c2 is vertical at the chassis middle c5, and the strut c2 is fixedly connected with chassis c5, chock plug c1, described
The chassis edge c5 is equipped with more than two inserting hole c4, and the inserting hole c4 quantity and the sliding mouth b1 quantity of bar shaped are equivalent, the two
Position relative misalignment guarantees that piston rod c and outer cylinder b intersects opposite sliding, is not easily disconnected from.
The one side of the pedestal 74 is horizontally fixed with an inverted L-type shape and is fitted into bar m, the chimeric bar m and extension
8 activity cooperation of frame, when two frame Extension supports, 8 junction is broken, the gravity that single hop is born can rate than heavier Extension support 8
First sink, mutually rub with the side chimeric bar m, realizes occlusion, be not easily disconnected from, cause safety accident.
Ring n is cleared up embedded with a circle in the outer cylinder b top end face middle, and the cleaning ring n has two layers of patch to constitute, patch
Surface irregularity, the patch are made of rubber material, open fit with 9 bottom wall of bridge floor naturally under the effect of the pressure,
It is in contact with bryophytes such as mosses on bottom wall, removes bryophyte, prevent excessively smooth bryophyte
Opposite sliding occurs for outer cylinder b top end face.
The outer cylinder b outer surface of cupular part and 72 bottom of telescopic rod are equipped with triangle deck a, the two triangle decks a is same
On one center line, horizontal median axis axial symmetry of the triangle deck a about central strut 7.
Using two frame Extension support 8 of hydraulic control in the split of bridge floor bottom on bridge floor, two frame Extension supports 8 are realized by latch fitting
Split is fixed, and service personnel stands on Extension support 8, hand steered a railing 6, the other hand center of rotation strut 7, rotation process
In, triangle deck a is slowly detached from Extension support 8, pedestal 74 be it is hemispherical, do not rub with Extension support 8, rotate smooth, rotation
After 90 degree, the chimeric bar m on pedestal 74 can be completely embedded into another frame Extension support 8, realize engaging, if latch fitting is disconnected
It splits, wherein 8 gravity of a frame Extension support is subjected in comparison, sinks first, be now placed in the chimeric bar of the central strut 7 on this
M can intersect friction with the generation of Extension support 8 side and be engaged, and the short time will not sink, to the time that service personnel withdraws, then
Afterwards, telescopic rod 72 is adjusted, negative pressure cylinder 71 is allowed to rise completely, cleaning ring n is in contact with 9 bottom wall of bridge floor first, not by telescopic rod 72
Disconnected to rise the pressure adjusted, the patch of two panels surface irregularity opens automatically, if there is the plant of the moss such as moss on contact surface
Object, will phase mutual friction therewith to realize the removal of bryophyte avoid the unstable and leakproofness of its cohesive position
Not strong problem, finally, drop-down, which is located at piston rod c, piston rod c and outer cylinder b inside outer cylinder b, intersects slide design, first is that shape
At negative pressure, negative pressure cylinder 71 is tightly adsorbed on 9 bottom wall of bridge floor, as the support construction of 8 end of Extension support, to improve Extension support 8
Total endurance, second is that prevent the disengaging of piston rod c, when pulling down piston rod c bar, it is sliding that chock plug c1 minimum altitude is higher than bar shaped
The highest point mouth b1 avoids air from entering in outer cylinder b from the sliding mouth b1 of bar shaped, can not form negative pressure, enhancing connection.
Problems solved by the invention is because being in the split of bridge floor bottom, and the stability of split position is wanted relative to two sides
It is low, once, the latch fitting of linking is broken, service personnel withdraw not in time, can because shake and extension rod of short duration inclination and
The safety accident present invention being combined with each other by above-mentioned component occurs, the present invention is matched jointly by negative pressure cylinder 71 and telescopic rod 72 etc.
It closes, while enhancing the connection of negative pressure cylinder 71 and 9 bottom wall of bridge floor using negative-pressure adsorption principle, as two frame Extension supports, 8 connecting points
Support construction, improve two frame Extension supports 8 endurance, this central strut 7 can also activity hide, cleaning ring n increase center
The leakproofness and stability that strut 7 is connected with bridge floor bottom wall.
