Description
Technical field
The present invention relates to a kind of liftable operation platform, particularly a kind of hydraulic elevation type operation platform that is used for major diameter and big height steel pressure regulation vertical shaft.
Background technology
The diameter of power station ground type steel pressure regulation vertical shaft and highly all very big; After normally adopting and set up superelevation layer steel pipe scaffold along the medial and lateral of the borehole wall, working operating platform re-lays the method for platform; And constantly rising with the rising of surge shaft; The shortcoming of this way is: not only need use a large amount of scaffoldings; Construction cost is big, and framed bent to set up, remove engineering quantity big, taken the engineering straight line duration; Have a strong impact on the engineering construction progress, security risk is big simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hydraulic elevation type operation platform, can constantly rise with the rising of surge shaft, thereby avoid setting up the problems that superelevation layer steel pipe scaffold brings.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of hydraulic elevation type operation platform, the borehole wall are provided with many perpendicular supports, and perpendicular support is provided with a plurality of pin shaft holes; Operation platform is provided with a plurality of ears plates, and the ears plate is through the pin shaft hole connection in bearing pin and the corresponding perpendicular support;
Below the ears plate, also be provided with lifting hydraulic cylinder, the hydraulic cylinder bearing of lifting hydraulic cylinder also is connected with the pin shaft hole that erects on supportting through bearing pin;
Each lifting hydraulic cylinder is connected with the Hydraulic Station of being located at operation platform.
Also be provided with guide rail between the described many perpendicular supports, opposite position is provided with roller on the operation platform, and roller rolls with guide rail and cooperates.
In the described operation platform, its bottom is made up of rack beams, and ears plate, lifting hydraulic cylinder and roller are connected with rack beams.
Described many perpendicular supports are evenly distributed on circumference, and described many guide rails are evenly distributed on circumference.
Described many guide rails are provided with groove, and roller is positioned at groove.
Described perpendicular support is three or four.
A kind of hydraulic elevation type operation platform provided by the invention through adopting the mode of hydraulic pressure from jacking, has been realized that working platform constantly rises with the rising of surge shaft, thereby has been avoided setting up the problems that superelevation layer steel pipe scaffold brings.For example framed bent to set up, remove engineering quantity big, taken the engineering straight line duration, have a strong impact on the engineering construction progress, technical problem such as security risk is big simultaneously.
The height of ground type steel pressure regulation vertical shaft reaches near 100 meters usually, and working platform sometimes also need carry engineering equipment, for example lifting appliance except needs carry construction material and workpiece.Therefore working platform is except easy of rise, and also requirement can load-carrying, requires load-carrying to surpass 30 tons usually.In addition, working platform also requires enough safety.
A kind of hydraulic elevation type operation platform provided by the invention has adopted the bearing pin location, and hydraulic pressure has been realized that working platform constantly rises with the rising of surge shaft, thereby avoided setting up the problems that superelevation layer steel pipe scaffold brings from the mode of jacking.For example framed bent to set up, remove engineering quantity big, taken the engineering straight line duration, have a strong impact on the engineering construction progress, technical problem such as security risk is big simultaneously.Adopt the mode of bearing pin location, simple to operate, and simplified the structure of single unit system, reduced and occurred the link of security incident easily, thereby improved safety.
The present invention has avoided taking repeatedly of operating platform to tear open, has guaranteed the smooth construction of surge shaft, has practiced thrift the engineering time, has saved construction cost, is fit to very much to take the surge shaft construction part of tearing operation platform open repeatedly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Fig. 1 is an overall structure vertical view of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 2.
The specific embodiment
In Fig. 1-Fig. 3, a kind of hydraulic elevation type operation platform, the borehole wall 9 are provided with many perpendicular supports 4, and perpendicular support 4 is provided with a plurality of pin shaft holes 10, and operation platform 1 is provided with a plurality of ears plates 3, and ears plate 3 is through pin shaft hole 10 connections in bearing pin and the corresponding perpendicular support 4;
Below ears plate 3, also be provided with lifting hydraulic cylinder 5, the hydraulic cylinder bearing 6 of lifting hydraulic cylinder 5 also is connected with the perpendicular pin shaft hole 10 that supports on 4 through bearing pin;
Each lifting hydraulic cylinder 5 is connected with the Hydraulic Station 8 of being located at operation platform 1.
In the scheme of optimizing, also be provided with guide rail 11 between the described many perpendicular supports 4, opposite position is provided with roller 7 on the operation platform 1, and roller 7 rolls with guide rail 11 and cooperates.Described many guide rails 11 are provided with groove, and roller 7 is positioned at groove.Thereby guarantee the stability and safety when operation platform goes up and down.
In the described operation platform 1, its bottom is made up of rack beams 2, and ears plate 3, lifting hydraulic cylinder 5 and roller 7 are connected with rack beams 2.
Described many perpendicular supports 4 are evenly distributed on circumference, and described many guide rails 11 are evenly distributed on circumference.
Described perpendicular support 4 is three or four.
Embodiment:
In Fig. 1-3; Rack beams 2 adopts i iron welding processing in processing factory to form; Treat that the surge shaft fabrication and installation are after exceed the ground certain altitude; In the borehole wall of surge shaft, be symmetrical set four perpendicular supports 4; Integral hoisting rack beams then 2, the ears plate 3 on the rack beams 2 is connected fixing with perpendicular support 4 through pivot pin.After accomplishing the installation of rack beams 2, be laid to operation platform 1 with steel plate thereon.Stability and safety when going up and down for the assurance operation platform also is provided with four guide rails 11 between four perpendicular supports 4, on guide rail 11, be welded with the steel plate of band groove, and roller 7 is embedded in the groove.
