Description

A node pipe hoisting framework

Technical Field

The invention belongs to the technical field of marine engineering, and in particular relates to a node pipe hoisting frame.

Background Art

At present, in the large-scale steel structure industry, especially in the offshore oil industry, there are more and more construction projects of offshore platforms, jack-up drilling platforms, deep-water floating platforms, etc. The deck plate is the most basic structure, and its main load-bearing structure is composed of large composite beams, nodes and finished beams. In order to ensure the bearing capacity of composite beams, nodes and finished beams, node pipes will be installed at the bearing points of composite beams, nodes and finished beams to strengthen the structure here.

However, due to the irregular shape of the node tube (semicircle and 1/4 circle) during installation, the node tube needs to be placed inside the composite beam, node and finished tube. Currently, the node tube is placed from one side and then moved to the installation reinforcement position little by little using temporary tooling. This method not only wastes working hours, but also requires spot welding of many temporary tooling, making the node tube installation inefficient.

Therefore, it is urgent to design a node tube lifting frame to solve the above-mentioned problem of installing the node tube.

Summary of the invention

In order to solve the technical problem mentioned in the background technology that the node tube is inserted from one side and moved to the installation reinforcement position little by little using temporary tooling, which wastes working time and requires spot welding of a lot of temporary tooling, resulting in low node tube installation efficiency, a node tube lifting frame is provided to solve the problem of installing node tubes.

To achieve the above purpose, the specific technical solution of the node pipe hanging frame of the present invention is as follows:

A node pipe lifting frame comprises an upper crossbeam and a lower crossbeam, a connecting beam is connected between the lower crossbeam and the upper crossbeam, the lower crossbeam is connected to the plate-wrapping lifting point arranged on the node pipe through a lifting pin, a lifting point is arranged on the upper crossbeam, a hand winch is connected to the lifting point, the verticality of the node pipe is changed by the hand winch, a telescopic sleeve is arranged on the lower crossbeam, a bottom supporting telescopic rod is slidingly arranged in the telescopic sleeve, the bottom supporting telescopic rod is connected to the plate-wrapping through a rotating handle, the plate-wrapping is abutted against the outer wall of the node pipe to adjust the angle of the node pipe.

Furthermore, the lifting point includes a first lifting point and a second lifting point, the first lifting point is connected with a fixed rigging, the second lifting point is connected with a hand chain hoist, and the length of the hand chain hoist is adjusted to change the verticality of the node pipe.

Furthermore, the outer wall of one end of the node tube is connected to a cladding plate hanging point, and one end of the lower beam is provided with a beam hanging point, and the hanging pin passes through the beam hanging point and the cladding plate hanging point in sequence to connect the lower beam to the node tube.

Furthermore, one end of the lower cross beam is vertically connected to a connecting beam, and one end of the connecting beam away from the lower cross beam is vertically connected to the upper cross beam, so that the upper cross beam, the connecting beam and the lower cross beam are connected in sequence to form a C shape.

Furthermore, a telescopic sleeve is vertically connected to one end of the lower cross beam away from the connecting beam, and a bottom supporting telescopic rod is vertically slidable inside the telescopic sleeve. By changing the extension length of the bottom supporting telescopic rod, the cladding plate can be abutted against the end of the node pipe away from the cladding plate hanging point.

Furthermore, one end of the bottom supporting telescopic rod is threaded with a rotating handle, and the rotating handle is inserted into one end of the bottom supporting telescopic rod and fixedly connected to the package plate.
