Abstract
The utility model relates to a spherical support construction field, concretely relates to spherical bearing installation auxiliary device. A spherical bearing installation auxiliary device which characterized in that: it includes four hydraulic jack, be equipped with the scale on hydraulic jack's the ejector pin, the top of ejector pin is equipped with the buphthalmia bearing, on four hydraulic jack install the base stone on the pier, be located four angle departments of base stone respectively, four angle correspondences of spherical bearing are laid on four hydraulic jack's buphthalmia bearing. This auxiliary device can assist the spherical bearing and fix a position in the installation and the regulation of elevation, and simple structure, easy operation, accuracy are higher moreover.
Description
Technical field
The utility model is related to spherical bearing construction field, and in particular to a kind of spherical bearing installation auxiliary device.
Background technology
In the process of construction of overpass, used as connection bottom bridge pier and the critical component of top bridge, it pacifies spherical bearing
The positioning of dress and the control of absolute altitude directly decide the design altitude of integrated deck, therefore the installation quality of spherical bearing is directly affected
To the quality into bridge, therefore, a series of construction and installation quality of spherical bearing are one of emphasis of construction monitoring.Spherical bearing
Construction need to measure control to its center axis and 4 absolute altitudes, then to carry out tune with design load poor.Under existence conditions, due to
Single spherical bearing weight carries out positioning and poor its accuracy of tune of absolute altitude does not much reach standard error up to more than 100 jins by manpower
Difference scope.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of spherical bearing installation auxiliary device, should
Servicing unit spherical bearing can be aided in position in installation process and absolute altitude regulation, it is and simple structure, easy to operate, accurate
Degree is higher.
For achieving the above object, technical solution adopted in the utility model is：
A kind of spherical bearing installation auxiliary device, it is characterised in that：It includes four hydraulic jacks, the hydraulic jack
The push rod on top is provided with scale, and the top of push rod is provided with buphthalmos bearing；Four hydraulic jacks are arranged on the pad on bridge pier
Shi Shang, respectively at four angles of pinner, four angles correspondence of spherical bearing is placed in the buphthalmos axle of four hydraulic jacks
Hold.
The beneficial effects of the utility model are：1. by hydraulic jack in combination with buphthalmos bearing, that is, spherical is solved
The seat problem that horizontal direction positioning is adjusted during mounting and adjusting, also solves the problems, such as vertical direction displacement.And hydraulic pressure
Jack can be time saving and energy saving with buphthalmos bearing, improves installation effectiveness.2. millimeter scale is set on the push rod of hydraulic jack
Value, it is convenient to read absolute altitude difference relative value.3. the utility model simple structure, easy to operate, accuracy are higher.

Specific embodiment
In order to more fully understand the utility model, the technical solution of the utility model is done with reference to embodiment and accompanying drawing
Further instruction（As Figure 1-3）.
A kind of spherical bearing installation auxiliary device, it includes four hydraulic jacks 1, the push rod 7 of the hydraulic jack 1
Scale is provided with, the top of push rod 7 is provided with buphthalmos bearing 8；Four hydraulic jacks 1 are arranged on the pinner 4 on bridge pier 5
On, respectively at four angles of pinner 4, four angles correspondence of spherical bearing 2 is placed in the buphthalmos axle of four hydraulic jacks 1
Hold on 8.
Spherical bearing installation auxiliary device supports four angles of spherical bearing 2, for adjusting the absolute altitude of spherical bearing 2, ox
Axis oculi holds 8 can make spherical bearing 2 realize easily moving horizontally on the apparatus, to the positioning for controlling its center axis.
Spherical bearing installation auxiliary device workflow：Spherical bearing 2 lift it is in place before, it is fixed at 2 four angles of spherical bearing
The position of point (S1, S2, S3, S4) is respectively provided with four hydraulic jacks 1, calculating loft draw four fixed points (S1, S2, S3,
S4) the top surface absolute altitude (H1, H2, H3, H4) and coordinate (D1, D2, D3, D4) of place's spherical bearing 2；Spherical bearing 2 is lifted into into bridge
On the pinner 4 of pier 5, in four insertion preformed holes 6 of bearing anchor pole 3.After the dropping place of spherical bearing 2 is in four hydraulic jacks 1, point
Coordinate that Ce Liang be S1, S2, S3, S4 not current（D1*、D2*、D3*、D4*）And absolute altitude（H1*、H2*、H3*、H4*）, and with calculating
The theoretical value for going out compares, and draws difference and Adjusted Option（Measurement first show that four point coordinates D1*, D2*, D3*, D4* are calculated and reason
By the difference of value, the movement scheme of spherical bearing 2 is drawn according to difference.Because bearing lower section is buphthalmos bearing, therefore adopt rubber hammer
Hammering spherical bearing 2 carries out the adjustment of position.Coordinate Adjusting in place after, again measure four absolute altitudes H1*, H2*, H3*, H4*
The difference with theoretical value is calculated, the Pass line adjustment scheme of spherical bearing 2 is drawn according to difference）.
It is described above be only Application Example of the present utility model, can not be limited with this certainly the utility model it
Interest field, therefore the equivalence changes made according to the utility model claim, still belong to protection domain of the present utility model.
