Abstract
The invention relates to a device and a method thereof for constructing a large-sized spherical tank construction platform. The device comprises a hanging nose arranged on a spherical tank shell slab,the hanging nose is provided with a support frame on which a climbing ladder is articulated, and a platform plate is paved between two adjacent climbing ladders on the same height. The work platform only needs to be constructed around weld joints on the inner wall of a spherical tank, then the construction requirement can be met, the occupied space is small, the detachment is convenient, and the device can be reutilized.
Description
Technical field
The present invention relates to a kind of large-size spherical tank operation platform and build device and building method thereof.
Background technology
When the spherical tank site welding technology, convenient for interior construction, need to build job platform around vertical and circumferential welded seam.Usually adopt the method for taking inner scaffold, promptly take full multilayer scaffold in spherical tank inside, each layer repaves the steel landing slab, is called " full thorax frame ", to satisfy about the workman and the operation needs.This method can guarantee that the spherical tank inwall has job platform near the position of weld seam, but owing to supporting mutually and being connected needs, do not need the position of job platform also to take scaffold from spherical tank inwall position far away, the scaffold in centre there is no actual value like this.
For 1000m
3Following spherical tank inner space is less, and the low performance of the scaffold utilization rate in this centre is also not obvious.Surpass 2000m for volume
3Large-size spherical tank, internal diameter surpasses 15m, when construction, if the inner method of taking full scaffold that adopts is built once length consuming time, and steel pipe scaffold must build when building from the bottom up, causes very big construction material waste simultaneously.And, build again again to operation once because spherical tank need roll over when operation operations such as welding, nondestructive testing, heat treatment, pressure test and remove scaffold.Can dismantle repeatedly and build like this, workload is big.
Summary of the invention
The objective of the invention is to address the above problem and provide a kind of need to center on spherical tank inwall weld seam and build job platform, can satisfy the construction needs, occupy the little and convenient disassembly in space, the large-size spherical tank operation platform that can reuse is built device and building method thereof.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
It comprises the hanging nose that is arranged on the spherical tank coverboard, and hanging nose is provided with bracing frame, is mounted with cat ladder on the bracing frame, is equipped with landing slab on adjacent cat ladder sustained height.
Above-mentioned bracing frame is a triangle, and one of them right-angle side is fixed on the hanging nose, and another right-angle side vertically withstands on the spherical tank coverboard.
Above-mentioned cat ladder is an arc, is provided with the spherical tank coverboard is vertical, and cat ladder is used to be made for about the industry personnel and is used for can laying landing slab on two adjacent cat ladders.
It comprises: (1), before Spherical Tank Shell Plates lifting, nose hung be fixed on the spherical tank coverboard, bracing frame is fixed on the hanging nose; (2), assembling spherical tank coverboard, will hang cat ladder on the bracing frame; (3), on the adjacent cat ladder of sustained height, lay landing slab; (4), on the spherical tank coverboard, be linked to be a whole circle successively by aforementioned (1), (2), (3) with landing slab; (5), spherical tank coverboard construction finishes and removes landing slab, cat ladder and bracing frame, hanging nose is retained on the spherical tank coverboard.
Above-mentioned bracing frame is a triangle, and one of them right-angle side is fixed on the hanging nose, and another right-angle side vertically withstands on the spherical tank coverboard.
Above-mentioned cat ladder is an arc, be arranged in parallel with the spherical tank coverboard, and cat ladder is used to be made for about the industry personnel and is used for can laying landing slab on two adjacent cat ladders.
Compared with prior art, the present invention has obtained following technique effect:
1, the present invention only need build job platform around spherical tank inwall weld seam, can satisfy the construction needs, and it is little to have a space of occupying, convenient disassembly, and can reuse, with low cost;
2, be fixed on the hanging nose by a right-angle side with triangle support frame, another right-angle side vertically withstands on the spherical tank coverboard, is reducing to have improved mounting stability on the spacial basis;
3, by cat ladder is designed to arc, and be provided with, also can reduce to occupy the inner space with the spherical tank coverboard is vertical.
Description of drawings
Fig. 1 is the schematic diagram of building of the present invention.
Wherein: 1-hanging nose, 2-bracing frame, 3-cat ladder, 4-spherical tank coverboard.
The specific embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of large-size spherical tank operation platform is built device, it comprises the hanging nose 1 that is arranged on the spherical tank coverboard 4, hanging nose is provided with triangle support frame 2, one of them right-angle side is fixed on the hanging nose, another right-angle side vertically withstands on the spherical tank coverboard, is mounted with and the vertically disposed arc cat ladder 3 of spherical tank coverboard by the hook on the cat ladder on the bracing frame, is equipped with landing slab on adjacent cat ladder sustained height.Above-mentioned tripod arc ladder device has convenient disassembly, as long as spherical tank coverboard internal diameter is close, the arc ladder is reusable.According to actual needs, build the arc ladder at differing heights place sectional and spread the steel landing slab when building, and face is all taken full from beneath.
The large-size spherical tank operation platform is built the building method of device, it comprises that (1) before the Spherical Tank Shell Plates lifting, hangs 1 with nose and is fixed on the spherical tank coverboard 4, is fixed on triangle support frame 2 on the hanging nose, one of them right-angle side is fixed on the hanging nose, and another right-angle side vertically withstands on the spherical tank coverboard; (2) assembling spherical tank coverboard will hang on the bracing frame and the vertically disposed arc cat ladder 3 of spherical tank coverboard; (3) on sustained height adjacent supports frame, lay landing slab; (4) be linked to be a whole circle with landing slab successively on the spherical tank coverboard by aforementioned (1), (2), (3), the same manner can be built multilayer construction operation platform at the spherical tank coverboard, can satisfy the welding of the spherical tank coverboard of differing heights and use; (5) spherical tank coverboard construction finishing dismounting landing slab, cat ladder and bracing frame, hanging nose is retained on the spherical tank coverboard, still can utilize when later annual test or repairing.Can landing slab be linked to be a whole circle at the spherical tank inwall.
Said apparatus or method are not limited to only be suitable for the large-size spherical tank interior construction, and outside construction also can be used in the same old way.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
