Description

A pillar assembly flip support

technical field

The utility model relates to the technical field of high-voltage power transmission and transformation equipment, in particular to a pillar assembly flip support.

Background technique

The assembly of the 1100kV column circuit breaker needs to switch between the horizontal posture and the vertical posture during the installation test, but the length of the pillar assembly is more than 10m, which increases the difficulty of posture conversion. In the prior art, the installation of the bracket assembly adopts the installation method of double cranes, and the upper and lower ends of the pillar assembly are used as the lifting points, and the installation is performed by the operator adjusting the position of the lifting points of the pillar assembly. The above-mentioned operation process requires a high level of hoisting operation, and the resource occupancy rate of the crane is high, and two cranes are required for hoisting at the same time, which leads to an increase in installation costs.

The Chinese utility model with the authorized notification number CN204384725U discloses a large-section, large-tonnage box-shaped member turning tool. The turning tool is composed of two semicircular tooling bodies that are combined and spliced to form a structure with an outer circle and an inner square. The turning tool The square hole in the middle is a turning hole. When in use, the square component is placed in the turning hole of a pair of turning tooling, and then the turning is realized by using the outer circular surface of the turning tooling. However, what the above-mentioned overturning tool solves is the attitude conversion of the member to be turned around its own axial direction, and cannot be applied to the attitude change of the longer member to be turned around its one end.

In view of the above-mentioned problems existing in the transformation of the pillar assembly posture and the lack of a pillar assembly posture transformation device in the prior art, it is an urgent problem to design a device that facilitates the transformation of the pillar assembly posture.

The arrangement of multiple starting support points of each bracket makes the column assembly in a stable state when the column assembly starts to be lifted, which avoids the horizontal tilting of the column assembly.

Further, the upper support part is an upper support plate detachably fastened with the lower support frame through a threaded fastening structure, and the upper support plate is provided with a connection for fastening and assembling the upper support plate and the pillar Bolt mounting holes for bolts to pass through. The screw fastening structure is easy to install and disassemble, and can achieve a good fixing effect.

Further, there are multiple bolt installation holes, all of which are arc-shaped long holes, and the arc-shaped long holes are arranged along the circumference of the same circle. This enables the pillar assembly flip support fixed by the screw fastening structure to be able to rotate moderately around the circle where the arc-shaped long hole is located, thereby realizing the fine adjustment of the pillar assembly flip support.

Further, a weight-reducing groove is provided on the upper support plate. The arrangement of the weight-reducing groove further reduces the weight of the pillar assembly overturning support, which is beneficial to the weight reduction of the pillar assembly overturning support.

Further, there are two weight-reducing grooves, and the two weight-reducing grooves are arranged symmetrically on opposite sides of the upper support plate. The symmetrical arrangement of the weight-reducing grooves is beneficial to the overall stability of the pillar assembly flip support.

On the basis of the above-mentioned solutions, the upper support part is further improved, and a hole-like structure for the pillar assembly transmission rod to penetrate is arranged on the support for the pillar assembly. The transmission rod of the pillar assembly penetrates into the interior of the pillar assembly flip support, so that the transmission rod of the pillar assembly can avoid contact with the ground during the attitude adjustment process, thereby ensuring that the pillar assembly transmission rod is not damaged.
