Description

Technical Field

[0001] The invention belongs to the technical field of levelness measuring tooling, and in particular relates to a levelness measuring tooling for auxiliary installation of a liftable busbar bridge. Background Art

[0002] At present, the measurement of busbar bridges for high and low voltage complete equipment in the industry is carried out by on-site surveying and mapping personnel using distance meters, plumb lines (plumbs), and tape measures. However, this type of measurement has the following deficiencies and defects: the busbar bridges for high and low voltage complete equipment are basically three-dimensional in size, with construction errors, design errors, and installation errors, which makes it difficult to determine the reference points. In addition, the on-site personnel's surveying and mapping is cumbersome, and repeated verification of dimensions is inefficient, which also brings inconvenience to designers and even huge losses to the company. The current busbar bridge measurement tooling is usually difficult to quickly install on the busbar bridge frame, and lacks a liftable adjustment mechanism, making it difficult to quickly adjust and fix the height of the measuring structure, which needs further improvement.

[0003] At present, the invention patent with patent number CN201110418489.0 discloses a bridge-type tooling for high-precision camera mounting surface measurement, which consists of a parallel gauge, an angle piece, a channel steel, a support and level adjustment device, a long support beam, a short support beam, a pad, a support rod and fasteners; it is characterized in that: the angle piece is connected to the side plate of the structure to be measured by two sets of fasteners, the channel steel is connected to the angle piece by two sets of fasteners, and then the long support beam is connected to the two channel steels by four sets of fasteners; the six supports and level adjustment devices are connected to the long support beam and the short support beam respectively by two sets of fasteners. Under the premise of meeting the high-precision requirements of the mounting surface measurement, the tooling transfers the measurement reference from the ground to the parallel gauge on the upper part of the top plate, solving the problem that traditional methods cannot measure within a large envelope range. However, the current busbar bridge measurement tooling is usually difficult to quickly install on the busbar bridge frame, and lacks a liftable adjustment mechanism, making it difficult to quickly adjust and fix the height of the measuring structure.

[0004] Therefore, the above-mentioned problem that the current busbar bridge measuring tool is usually difficult to be quickly installed on the busbar bridge frame, and lacks a liftable adjustment mechanism, making it difficult to quickly adjust and fix the height of the measuring work needs to be solved urgently so that the levelness measuring tool can be quickly installed on the busbar bridge frame and has a liftable adjustment mechanism to quickly adjust and fix the height of the measuring structure.
