Problems solved by technology

However, in the heavy-duty lifting and lowering device using rigid tie rods, since multiple rigid tie rods need to be used for connection, the joints between the rigid tie rods cannot pass through the locking nuts in the device; Commonly, the existing rigid tie rods are easily deformed or even broken by the impact of the horizontal force of wind or waves

Abstract

The invention discloses a rigid pull rod heavy load lifting and lowering device, and belongs to the field of civil engineering construction equipment. The device comprises at least two base beams, a large-tonnage jack, distribution beams, a rigid pull rod, a connector and nuts. The base beams are evenly distributed on the periphery of the rigid pull rod. The lower distribution beam is arranged at the upper end of the base beam. The upper and lower distribution beams are provided with through holes for enabling the rigid pull rod to pass. The rigid pull rod and the upper distribution beam are connected through an upper saddle and the upper split nut. The rigid pull rod and the lower distribution beam are connected through a lower saddle and a lower split nut. The upper saddle and the lower saddle are provided with through holes with the external diameter larger than the connector. The rigid pull rod heavy load lifting and lowering device is simple in structure, reasonable in design, and capable of preventing damage caused by wind waves to the rigid pull rod in the rigid rod lifting and lowering process.

Description

technical field [0001] The invention belongs to the field of civil construction equipment, in particular to a heavy-duty lifting and lowering device of a rigid tie rod. Background technique [0002] Heavy load lifting and lowering is a common construction method in the field of civil engineering. It is mainly suitable for the installation of temporary and permanent structural parts, machinery and equipment and other heavy-duty objects. [0003] In the lifting and lowering construction, the vertical tie rods used can be divided into flexible tie rods and rigid tie rods. Flexible tie rods mainly use steel strands and steel wire ropes; rigid tie rods mainly use precision-rolled rebar and high-strength steel tie rods. Flexible tie rods are generally constructed with continuous jacks. However, there are few large-tonnage continuous jacks on the market, and the cost is high. The lifting and lowering of heavy loads are completely restricted by the provision of continuous jacks. ...
