Abstract
The utility model discloses a fixing device of an annular orbit, which relates to hoisting machinery, and solves the problems that an existing nuclear power station annular crane is small in adjustment amount between the annular orbit and a bearing beam, and is not suitable for relatively fixed occasions of an annular support rail beam and a plant position. A plurality of orbit base plates are arranged between the annular orbit and the annular support rail beam, a mounting slot is arranged in the middle of each orbit base plate, long round bolt holes are arranged on the two ends of the orbit base plate, the width of the mounting slot is bigger 20-40mm than the width of the annular orbit, the annular orbit is arranged on the center of the mounting slot, and a group of adjusting plates and a wedge-shaped plate are arranged in the mounting slot and the two sides of the annular orbit. The fixing device of the annular orbit is used for nuclear power station annular cranes, can meet the requirement of the adjustment amount of an orbit radius relative to a plant, and also can guarantee the crane to be in the best operation state by adjusting.
Description
Technical field
The invention belongs to elevator machinery, particularly a kind of circular orbit of used in nuclear power station ring-shaped crane.
Background technology
The nuclear station ring-shaped crane needs nuclear island factory building is done prestress and pressure test after finishing the nuclear station military service in installation stage before the nuclear station operation.When doing prestress, the radius of factory building can dwindle 10～15mm; When doing pressure test, the factory building radius can increase 10～20mm.In addition, in the nuclear station operational process, because the factors such as variation of factory building under the creep of Factory Concrete and the accident condition, the radius of factory building all can change.The radius that is fixed on the circular orbit on the factory building support rail beam also will change along with the variation of factory building radius.In order to guarantee the good operation of hoisting crane, and reach certain accuracy of positioning, must be to the radius of circular orbit, and the overlap ratio at the center of circular orbit and factory building center adjusts, and need to be about 20～30mm by adjustment amount on radial direction.
The circular orbit of existing nuclear station ring-shaped crane and the fixing means between the annular support rail beam have two kinds.One of method is as shown in Figure 4: the cross section of track is rectangle, and track 1 directly is welded on the support rail beam 7, and track and support rail beam form one.Some sections circular orbits and support rail beam form an annular, and processing guarantees by originating firm for the diameter tolerance of circular orbit, out of roundness tolerance, tread planeness, and is relatively fixing between track and the support rail beam.Method two as shown in Figure 5: some sections hoisting crane dedicated track 1 (I shape track) are fixed on plane on the annular support rail beam 7 with conventional rail pressing plate 2.Although track can move with respect to annular support rail beam, the radius adjustment amount of circular orbit is very little, is generally 2～4mm, does not satisfy needed adjustment amount.
The fixing means of two kinds of circular orbits of this of prior art, the radially adjustment of its circular orbit are to realize by the relative position of adjusting between support rail beam 7 and the factory building (supporting bracket 8).Prior art is only suitable for adopting bolt 9 to be connected in support rail beam 7 and factory building (supporting bracket 8), and the position situation that can relatively move, and is not suitable for the relatively-stationary occasion in position between annular support rail beam 7 and the factory building (support bracket 8).
Summary of the invention
The objective of the invention is the deficiency for the prior art existence, a kind of anchor fitting of circular orbit is provided, the anchor fitting adjustment amount that solves between existing nuclear station ring-shaped crane circular orbit and the annular support rail beam is very little, is not suitable for the problem of the relative stationary applica-tions in position between annular support rail beam and the factory building.
The present invention is achieved through the following technical solutions:
A kind of anchor fitting of circular orbit, comprise: the circular orbit, rail pressing plate, bolt assembly, the annular support rail beam that are formed by some sections tracks, circular orbit is connected with annular support rail beam with rail pressing plate, bolt assembly, it is characterized in that: be lined with some track pads between described circular orbit and the described annular support rail beam, every described track pad middle part has mounting groove, and every described track pad two ends are provided with in the orbit radius direction and are oblong bolt hole; The width dimensions a of described mounting groove is than the large 20～40mm of width dimensions b of circular orbit; Described circular orbit is placed on the center of described mounting groove, in described mounting groove, the gap location of circular orbit both sides, places one group and adjusts plate and a clap board.
The present invention compared with prior art has the following advantages and beneficial effect:
In the radially irremovable situation of annular support rail beam with respect to factory building, lean on circular orbit itself with respect to the movement diametrically of annular support rail beam with device of the present invention, adjust diameter tolerance, out of roundness tolerance and the endless track center of circular orbit and the overlap ratio at factory building center, make it reach required value, to adapt to the variation of the factory building diameter that brings because of prestress, pressure test and concrete creep., satisfied the adjustment amount requirement of nuclear station ring-shaped crane circular orbit radius with respect to factory building, and made ring-shaped crane reach certain accuracy of positioning, thereby guaranteed that the nuclear station ring-shaped crane is in optimal operational condition.

The specific embodiment
As shown in Figure 1, 2, 3, a kind of anchor fitting of circular orbit comprises: by circular orbit 1, rail pressing plate 2, bolt assembly 3, the annular support rail beam 7 that some sections tracks form, circular orbit 1 usefulness rail pressing plate 2, bolt assembly 3 are connected with annular support rail beam 7; Be lined with some track pads 4 between described circular orbit 1 and the annular support rail beam 7, every described track pad 4 middle parts have mounting groove 4-1, and every described track pad 4 two ends are provided with in the orbit radius direction and are oblong bolt hole 4-2; The width dimensions a of described mounting groove 4-1 is than the large 20～40mm of width dimensions b of circular orbit 1; The center of described mounting groove 4-1 overlaps with the theoretical centerline of described circular orbit 1, described circular orbit 1 is placed on the center of described mounting groove 4-1, in described mounting groove 4-1, the gap location of circular orbit 1 both sides, place one group and adjust plate 6 and a clap board 5 (namely with a clap board and one group of gap of adjusting plate filling circular orbit 1 both sides).
When needs were adjusted orbit radius R, it is inboard that the adjustment plate 6 in circular orbit 1 outside is moved on to the ring rail, and the diameter of circular orbit 1 is increased; The adjustment plate 6 of circular orbit 1 inboard is moved on to the ring rail outside, the diameter of circular orbit 1 is reduced.Along the position that the tangent to periphery direction moves clap board 5, can finely tune the position of track, and circular orbit 1 is accurately located with respect to track pad 4.By the mobile position of adjusting plate 6, can make the radius of circular orbit 1 reduce or increase 10～15mm.Utilize oblong bolt hole 4-2 on the track pad 4, by the relative position of moving track backing plate on the factory building radial direction, can further adjust the radius of circular orbit 1.
