Description

TECHNICAL FIELD

[0001] The utility model belongs to civil engineering technical field, more specifically, especially, it relates to a large -scale pipe hoisting device. BACKGROUND

[0002] In the civil engineering technical field, when the water supply and drainage system is constructed, a variety of large pipe fittings are needed to form a water supply and drainage network. When installing large pipe fittings, a crane or other hoisting machinery is generally used to hoist and install large pipe fittings. When hoisting large pipe fittings using hoisting machinery, a large pipe fitting hoisting device is needed. Most existing large pipe fitting hoisting devices are composed of steel cables, buckles, lifting rings and hooks. Construction personnel use steel cables to loop around or pass through large pipe fittings, use buckles to fix the pipe fittings and lifting rings and hooks, and use lifting rings and hooks to connect hoisting machinery for lifting.

[0003] The existing application number CN201820709180.4 utility model proposes a pipe fitting hoisting device, which includes a support clamping part and a lifting part. The support clamping part includes a support beam, side clamping plates, a bottom plate and a clamping plate. The support beam is located at the upper part, and the lower part of the two side edges is slidingly connected with the corresponding side clamping plates. The side clamping plates are connected with a tightening device. The tightening device extends two telescopic arms and connects with the corresponding side clamping plates. The bottom of the side clamping plate is connected with an inclined bottom plate. The corresponding bottom plates on both sides form a clamping space that is large at the top and small at the bottom. The clamping plate is connected to the middle part of the support beam and extends downward into the space between the side clamping plates. The device is suitable for hoisting work of tubular parts. The lifting part can use existing travelling cranes and related equipment. Each segment can be clamped separately, increasing the number of clamping points and improving the stability of clamping. It also saves the weight of the components, making lifting easier and more convenient to control, improving production efficiency and being suitable for mass production places. (ESM) The same invention has been applied for an invention patent on the same day.

[0004] Based on the above, most existing large pipe fitting hoisting devices use steel cables to loop around or pass through large pipe fittings for fixation. However, the looping method is not convenient when the pipe is lying flat, as it requires the cooperation of forklifts, excavators and other machinery, which is more cumbersome and increases the cost of machinery. Although it is easy to install through the inner cavity of the pipe, it is easy to cause stress on both ends of the pipe, causing the rope to stretch and the ends of the pipe to break or deform.
