Abstract
The utility model relates to a limiting adjustable support for bridge jacking. The support comprises an upper support plate and a lower support plate. A ball-faced groove is formed in the top face of the lower support plate, a middle support plate is arranged on the top face of the lower support plate, the bottom face of the middle support plate is a ball face, and the bottom face of the middle support plate is matched with the ball-faced groove of the lower support plate. A square groove is formed in the top face of the middle support plate, a plane stainless steel slide plate is arranged inside the square groove in an embedded mode, and a plane slide plate is arranged between the plane stainless steel slide plate and the upper support plate. The upper support plate is in the shape of an inverted square basin, more than two limiting bolts are respectively and evenly distributed on the basin edges of the four lateral faces of the upper support plate, and a locating nut is arranged on each limiting bolt in a matching mode. Due to the fact that the limiting mechanism is additionally arranged on the four lateral faces of the upper support plate, the largest slippage of the support can be adjusted according to project demands, and the safety of jacking projects is improved; the limiting adjustable support for bridge jacking is convenient to machine, and can be used repeatedly in different projects, save resources and lower cost.
Description
Technical field
The utility model belongs to the bridge pad field, is specifically related to a kind of limit adjustable bridge jacking special carrier.
Background technology
Bridge jacking refers to the operating process that jack-up systems such as adopting hydraulic pressure is raised the bridge major bearing structures.The jacking of bridge may need the longitudinal gradient to old bridge, horizontal wall inscription is adjusted, cause the beam of jacking to know from experience the suitable bridge of generation to the rotation with direction across bridge, due to rotation, beam length, deck-siding can change in the horizontal direction, so require the bearing used in the jacking process should have turning power also the ability of horizontal slip will be arranged, for guaranteeing safety, need be controlled the slippage in the jacking process, different bridge jacking engineerings, the permission slippage difference that the different directions of bridge may occur, existing jacking bearing only has maximum slippage restriction, but do not possess the function of regulating maximum slippage according to concrete engineering, can take the method for the concrete customization of concrete engineering to solve this problem, and because the jacking engineering is different, the customization bearing is difficult to recycle, and the jacking engineering is consuming time shorter, short-term just can not be used after using again, increased the cost of waste and the jacking of resource.
The utility model content
The defect that can not recycle for overcoming bearing that the maximum slippage of jacking bearing in prior art can not regulate, customize, the improvement of the utility model based on to spherical bearing provides a kind of limit adjustable bridge jacking special carrier.
Concrete technical scheme of the present utility model is as follows:
A kind of limit adjustable bridge jacking special carrier comprises upper base plate 1 and lower seat board 8, described lower seat board 8 is short four prisms cylinder, the end face of lower seat board 8 is spherical groove, the end face of lower seat board 8 is provided with middle seat board 5, the bottom surface of middle seat board 5 is sphere, and the sphere of middle seat board 5 coordinates with the spherical groove of lower seat board 8; The end face of middle seat board 5 is provided with square groove, is embedded with plane stainless steel slide plate 3 in described square groove, between described plane stainless steel slide plate 3 and upper base plate 1, is provided with plane slide plate 2; It is characterized in that: described upper base plate 1 is the square peviform of back-off, and 1 four sides of upper base plate are laid with respectively the caging bolt 4 more than two on the De Pen limit, on each caging bolt 4, coordinates and is provided with setscrew nut 9.
Be laid with respectively four caging bolts 4 on four basin limits, side of upper base plate 1.
Useful technique effect of the present utility model embodies in the following areas:
(1) the utility model has increased position-limit mechanism in the surrounding of upper base plate, can adjust the maximum slippage of bearing according to requirement of engineering, increases the safety of jacking engineering;
(2) the utility model is easy to process, can be in a plurality of jacking engineerings Reusability, economize on resources, reduce costs.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The sectional view that Fig. 2 is I-I place in Fig. 1.
The sectional view that Fig. 3 is II in Fig. 1-II place.
In upper figure, sequence number is: upper base plate 1, plane slide plate 2, plane stainless steel slide plate 3, caging bolt 4, middle seat board 5, middle seat board sphere 6, lower seat board sphere 7, lower seat board 8, setscrew nut 9.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment:
Referring to Fig. 1, a kind of limit adjustable bridge jacking special carrier comprises upper base plate 1 and lower seat board 8.Lower seat board 8 is short four prisms cylinder, and the end face of lower seat board 8 is spherical groove, and the end face of lower seat board 8 is provided with middle seat board 5, and the bottom surface of middle seat board 5 is sphere, and the sphere of middle seat board 5 coordinates with the spherical groove of lower seat board 8; The end face of middle seat board 5 is provided with square groove, is embedded with plane stainless steel slide plate 3 in square groove, between plane stainless steel slide plate 3 and upper base plate 1, is provided with plane slide plate 2.The square peviform that upper base plate 1 is back-off, 1 four sides of upper base plate are laid with respectively the caging bolt 4 of four on the De Pen limit, on each caging bolt 4, coordinate setscrew nut 9 is installed, and see Fig. 2 and Fig. 3.
Operating principle of the present utility model is as follows:
By adjusting the gap between caging bolt 4 and middle seat board 5, can control the slippage maximum value between upper base plate 1 and middle seat board 5 at both direction, thereby play spacing effect, by different spacing adjustings, can become unidirectional spacing sliding support, bidirectionally limited sliding support and fixed bearing (being that two-way slippage all is restricted to 0).
Claims (2)
