Description
Technical field
The utility model belongs to Municipal Engineering Construction technical field, is related to during a kind of earth pressure balance mechanical jacking, cloth
Put the multiple step format telescopic rail at relay well.
Background technology
Relay well technology is that solve one of excessive maximally effective measure of long-distance pipe-jacking construction jacking force, and it makes
Long-distance pipe jacking is possibly realized, and construction safety performance is improved and ensured.The technology passes through the certain position in jacking pipeline
Jacking is gradually segmented after installation relay well, in the case where not increasing main top pumping plant top power, do not change back form and structure, is led to
Cross Relay Technique and realize long-distance pipe jacking.
Earth pressure balanced push pipe is slagged tap typically to be carried out using rail battery truck, and battery truck track not only needs continuously to lay,
And there must be certain bearing capacity；And relay well operation principle seeks to reciprocal stretching motion to realize segmentation jacking.
How both to ensure that battery truck is passed through at relay well, enabled to relay well normal work again, and be to need to solve the problems, such as.
The method used at present is the dismountable guide rail of installation at relay well.Guide rail is dismantled when relay well works with full
Foot its reciprocal telescopic requirement, guide rail is installed to meet that it passes through by preceding in battery truck.Such a method not only wastes time and energy, and
Frequently dismounting can cause rail attachment point abrasion aggravation, influence normally to use.
The content of the invention
The purpose of this utility model is arranged in multiple step format at relay well during being to provide a kind of earth pressure balance mechanical jacking
Telescopic rail.The telescopic rail need not frequently be dismantled, automatically turn on closure, solve problems of the prior art, real
The normal work of relay well and smoothly passing through for track battery truck are showed.
The utility model the technical scheme adopted is that
Multiple step format telescopic rail at a kind of mechanical jacking construction relay well, it is characterized in that：
Stretched including groove profile sleeper, sleeper connection transverse slat, flexible rail, rail connection transverse slat, substep shrinking connecting-rod and substep
Contracting square hole,
The groove profile sleeper connects transverse slat by sleeper and is connected, and the flexible rail is placed in groove profile sleeper and passes through rail
Connection transverse slat is connected, and described substep shrinking connecting-rod one end is welded on rail connection transverse slat both sides, and it is flexible that the other end is laid in substep
In square hole, the flexible square hole of the substep is laid in rail connection transverse slat both sides, and extendable room is provided for substep shrinking connecting-rod.
The power of above-mentioned substep shrinking connecting-rod is the top power using relay well and main top.
The quantity of above-mentioned substep shrinking connecting-rod and the flexible square hole of substep matches.
Above-mentioned connected mode is welding or nut connection.
The beneficial effects of the utility model are
The automatic shutter of middle guide rail is realized by the use of such a telescopic rail, is not only reaching relay well just
The smoothly current purpose often to work with track battery truck, and the manpower that guide rail is frequently dismounted in original technology is saved, so as to
Improve jacking efficiency.
Brief description of the drawings
Fig. 1 is multiple step format telescopic rail profile.
Fig. 2 is multiple step format telescopic rail plan.
Reference：1- groove profile sleepers, 2- sleepers connection transverse slat, 3- stretch rail, and 4- rail connection transverse slat, 5- stretches step by step
Contracting connecting rod, the flexible square hole of 6- substeps.
Embodiment
Referring to Fig. 1 and Fig. 2, multiple step format telescopic rail at a kind of mechanical jacking construction relay well, including groove profile sleeper 1, rail
Pillow connection transverse slat 2, flexible rail 3, rail connection transverse slat 4, substep shrinking connecting-rod 5 and the flexible square hole 6 of substep,
The groove profile sleeper 1 connects transverse slat 2 by sleeper and is connected, and the flexible rail 3 is placed in groove profile sleeper 1 and passed through
Rail connection transverse slat 4 is connected, and described one end of substep shrinking connecting-rod 5 is welded on rail connection transverse slat 4 both sides, and the other end is laid in point
In the flexible square hole 6 of step, the flexible square hole 6 of the substep is laid in rail connection transverse slat 4 both sides, provides and stretches for substep shrinking connecting-rod 5
Contracting space.
The power of substep shrinking connecting-rod 5 is the top power using relay well and main top.
The quantity of substep shrinking connecting-rod 5 and the flexible square hole 6 of substep matches.
Connected mode is welding or nut connection.
During work, using relay well and the top power on main top, pass through the substep shrinking connecting-rod being laid on rail connection transverse slat 4
5 complete the unlatching of telescopic rail and closure, and the drawing passed through completes the opening and closing of block rail.Groove profile sleeper 1 in the utility model
Support and guide effect are played in whole device, ensure that and do not offset during the flexible rail stroke of substep；Rail connection is horizontal
Plate 4 not only enhances rail stability, and provides space for substep shrinking connecting-rod, the flexible square hole of substep.
During relay well start-up operation jacking（The main top in rear stops jacking, slag waggon stops mucking haulage）, substep shrinking connecting-rod 5 leads
Contracting rail 3 of extending is pulled open successively in groove profile sleeper 1, forms discontinuous rail, reserves the flexible square hole 6 of substep；
Rear it is main top start-up operation jacking when（Relay well stops jacking, slag waggon starts to muck haulage）, substep shrinking connecting-rod 5
The flexible rail 3 of traction closes successively in groove profile sleeper 1, forms continuous rail, is run for battery truck.
