Description

Movable hanging bracket for offshore platform

Technical Field

The utility model belongs to offshore platform conveyer especially relates to a removal gallows that offshore platform used.

Background

Because the construction space of the offshore platform is limited, the construction materials are temporarily hoisted in place and generally manually lifted or temporary hoisting points are welded on an upper structural beam and lifted by a chain block, and the methods often have the defects of low transportation efficiency, high safety risk, damage to the paint of the original structure and the like. At present, the mode of manual lifting or welding temporary hoisting points on an upper structural beam and lifting by a chain block is generally adopted for the dumping and lifting of construction materials on a platform, and the defects of low dumping efficiency, high safety risk and the like exist. Especially for the installation in place of heavy (over 500 kg) bulk material and pipelines, there is a lack of an effective tool to increase efficiency, especially in the case of structurally unavailable hoists above the material, which results in extended construction periods. It becomes especially important to develop a movable hoisting frame which is effective and improves the installation efficiency.

SUMMERY OF THE UTILITY MODEL

The problem to prior art exists, the utility model relates to an interim frock gallows, its bearing can reach more than 2 tons, can load heavier material like elbow, tee bend, flange, valve etc. of heavy-calibre, and single gallows can the lifting pipeline nipple joint, can also adopt the form of double hanger intermodal, lifting long pipeline, valve or equipment etc, the utility model has the advantages of simple structure, installation, dismantlement and transport are convenient, use extensively.

The utility model discloses a solve prior art problem, the utility model discloses a following technical scheme:

a mobile pylon for an offshore platform; the hanger comprises a hanger body, wherein the hanger body comprises a group of detachable first hanger bodies and a group of detachable second hanger bodies, and each hanger body comprises a base, an assembling body and a supporting body; a connector is arranged between the first hanger body and the second hanger body, the base is connected with the assembling body through a flange, and the assembling body is connected with the supporting body through a flange.

The base is provided with a semicircular holding clamp.

The base is connected with a caster.

The assembly body is a pipe body with a three-way structure.

The support body is a pipe body with adjustable length.

Advantageous effects

Compared with the prior art, the utility model has the advantages of:

1. bearing and lightweight design: each component of the hanger structure can bear more than 2 tons, the weight of each component is not more than 100kg, and 2 people can easily lift the hanger. When the hanger is used for combined construction, construction risks can be reduced, the work efficiency is more than 4 times that of the common pipeline hoisting mode, and the work efficiency is 2 times that of the common pipeline hoisting mode, so that the work efficiency is improved by more than 50%.

2. Can be connected in parallel by two frames: two hangers can be connected in parallel through the horizontal pipe section to carry out the hoist and mount operation, have promoted the hoist and mount practicality to large-scale pipe fitting or equipment, promote the holistic hoist and mount ability of gallows.

3. Design of adjustable height: the height can be adjusted according to the construction condition by adjusting the number of the straight pipe sections.

4. Various base designs: can be according to the construction site difference, select suitable base, promote the general usefulness of device.

5. The utility model does not need to weld the hoisting point, thus reducing the requirements on the construction site; the hanger is convenient to detach at any time and is used repeatedly; the electric hoist is used, so that the risk and labor intensity of personnel operation are reduced; the method has the characteristics of low cost, simple operation, safe and efficient construction and the like.

Fig. 2 is a parallel use state diagram of 2 movable hangers for an offshore platform.

Detailed Description

The technical solution of the present invention will be further explained with reference to fig. 1.

As shown in fig. 1, the present invention is a mobile crane 100 for an offshore platform; the lifting frame comprises a group of detachable first lifting frame bodies 101 and a group of detachable second lifting frame bodies 102, wherein each lifting frame body (101,102) is composed of a base 103, an assembling body 104 and a supporting body 105; first gallows body 101 with be provided with connector 110 between the second gallows body 102, when hoist and mount use, carry out the hoist and mount of heavy goods through electric hoist 106 on the connector, the utility model provides a connector 106 is connected by two flanged risers of H shaped steel and supporter 105, and the bearing can reach more than 1 ton, and H shaped steel 106 can hang electric hoist, and the flanged riser can pass through bolted connection with straight tube section 105. The base 103 is connected with the assembly body 104 through a flange, and the assembly body 104 is connected with the support body 105 through a flange; the base 103 is movably connected with a caster 107, so that a hanger with the caster 107 can conveniently move on the deck, and the whole body can be prevented from sliding through braking during hoisting operation; meanwhile, the position fixing construction of the hanger 110 on the cambered surface places such as the trestle is convenient; the base 103 is provided with a semicircular holding clamp 108; the utility model discloses in supporter 105 adopts the seamless steel pipe that excels in of a both ends flanged, when being used for the not operation of lifting by crane of co-altitude, the combination of many straight tube sections of accessible changes the whole height of gallows.
