Abstract
The utility model discloses an overhead construction platform device for truss type spug legs of a jack-up drilling rig, which comprises a platform board (1). The platform board (1) is formed by two platform structures which are butted with each other, a guardrail is additionally arranged on the periphery of the platform board, a reinforcing section bar (5) and a reinforcing bracket (6) are arranged on the lower portion of each platform structure, a fastening slot is arranged between the two platform structures which are butted with each other, and teeth matched with a main cord rack of a spug leg (8) are arranged on the inner side of the fastening slot. In addition, connecting plates (4) are additionally arranged on the side walls of the butted joint of the two platform structures, and the two platform structures are fixedly connected by bolts penetrating through two sides of the connecting plates. Due to the fact that the conventional butt straps and scaffolds are replaced, the overhead construction platform device is more convenient in mounting and dismounting and has the advantages of simple structure, low manufacturing cost and convenience in mounting and dismounting.
Description
Technical field
The present invention relates to a kind of truss framed leg high-altitude construction operation device, in particular, a kind of self-elevating drilling platform truss framed leg high-altitude construction operation stage apparatus is provided.
Background technology
The self-elevating drilling platform that has truss type pile leg structure, its pile leg structure segmentation is the assembling welding on ground, and then multilayer spud leg segmental structure is erect, and docks in the high-altitude successively from top to bottom.The spud leg height is higher, and work high above the ground is difficulty very.Conventional method is: the installation exercise elevator, set up interim boatswain chair scaffold device as operation platform at every layer of spud leg folding face, and cause that subsidiary operation time is long, to set up difficulty big, influence operating efficiency.
Summary of the invention
To above-mentioned technical problem, the present invention provides a kind of high-altitude operation platform device, and its purpose is, makes things convenient for the welding procedure operation of self-elevating drilling platform truss type pile leg structure high-altitude, and the operating environment of safety and stability is provided.
In order to achieve the above object, the present invention provides a kind of self-elevating drilling platform truss framed leg high-altitude operation platform device, comprises the landing slab that is formed by two platform structure butt joints; Be equipped with guardrail around on the said landing slab; The bottom of each said platform structure is provided with stiffening profile and deep bracket.Bayonet socket is offered at said two platform structures middle part of butt joint, and the inboard of said bayonet socket is provided with the profile of tooth that cooperates with spud leg main chord tube tooth bar.In addition, be equipped with junction plate on the sidewall of the joint of said two platform structures, make said two platform structures be connected mutually through the bolt that wears respectively in both sides.
Apparatus of the present invention rely on spud leg main shipboard tube rack structure to be fixed on spud leg main shipboard tube both sides, and it is fixing to use junction plate and bolt that this device is connected, thereby forms firm construction operation platform.This device carried out in the pile leg structure ground construction stage, and the permanent position closes up the soldered lower end at pile leg structure, installation before the pile leg structure upper air installing.Core fixed position in said this device is the tooth bar jig, relies on the tooth bar jig, and this device is divided into two, relies on junction plate and bolt, and two are fixed on the spud leg main shipboard tube.This device operating area has structure to strengthen on platform under the flat upper surface, its effect is to increase platform to receive force intensity.Guardrail is installed around this apparatus platform.
A kind of self-elevating drilling platform truss framed leg of the present invention high-altitude operation platform device; This device relies on spud leg main shipboard tube rack structure to be divided into two and is fixed on spud leg main shipboard tube both sides; Use junction plate and bolt that two devices closely are fixed on main shipboard tube tooth bar place, thereby form firm construction operation platform.This device carried out in the pile leg structure ground construction stage, and the permanent position closes up the soldered lower end at pile leg structure, installation before the pile leg structure upper air installing.This device replaces traditional attachment strap and scaffold mode, installs, dismounting is more convenient, and in the spud leg high-altitude welding procedure stage, the operating personnel relies on that spud leg is inner to be installed the elevator entering and be positioned on this device in high-altitude, can carry out the long period operation continuously, and is safe and reliable.The present invention has simple structure, cheap, easy installation and removal characteristics, and therefore more traditional scaffold technical method has marked improvement on economy and use value.
Description of drawings
Fig. 1 is apparatus of the present invention plane structure sketch map;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 be among Fig. 1 B-B to cross-sectional view;

The specific embodiment
Below in conjunction with accompanying drawing apparatus of the present invention are done further explanation.
Shown in figure 1-4, self-elevating drilling platform truss framed leg of the present invention high-altitude operation platform device comprises the landing slab 1 that is formed by two platform structure butt joints.Be provided with guard rail 7 around on the installation landing slab 1.The middle part of platform 1 is according to spud leg 8 main shipboard tube tooth bar geomeries, and the bayonet socket 2 of core stationary rack jig structure is accomplished in cutting.
In addition, the bottom of each platform structure is provided with stiffening profile 5 and deep bracket 6, and effect is the force intensity that receives that increases platform.Landing slab 1, reinforcement 5,6 dresses are welded into monolithic devices.
Two platform structures rely on junction plate and bolt 4 to be fixed on the spud leg main shipboard tube 8.Concrete reference is shown in Figure 3, is equipped with junction plate 4 on the sidewall of the joint of two platform structures, makes said two platform structures be connected mutually through the bolt that wears respectively in both sides.
Pile leg structure is after ground welding assembly operation is accomplished; Apparatus of the present invention are fixed on pile leg structure main shipboard tube upper end place; After treating that more the installation of the preceding paragraph spud leg is located, utilize this device to carry out high-altitude welding procedure operation between two sections pile leg structure main shipboard tube weld seams.Apparatus of the present invention permanent position should be in spud leg segmental structure upper end, purpose be for upper strata spud leg segmentation more therewith the spud leg segmentation welding location, main shipboard tube high-altitude operation platform is provided.The elevator of personnel through set up in the spud leg temporarily gets into and carries out welding construction working in location, spud leg high-altitude on this high-altitude operation platform face.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
