Centering device for building pipes based on the principle of synchronous motion

Abstract

The invention relates to the technical field of building measurement, and discloses a centering device based on a synchronous movement principle for a building pipeline. The device comprises a face plate, and a connecting rod is fixedly connected to the front surface of the face plate; an output shaft of an engine is movably connected with a first bevel gear, so that the first bevel gear is rotated, and a first sliding rod is driven to rotate while the first bevel gear is rotated; the first sliding rod is provided with a first thread, so that a first sliding block is rotated to slide in the first sliding groove, and a first positioning rib is driven to move by sliding of the first sliding block; and the first bevel gear and a second bevel gear are meshed with each other, so that the secondbevel gear is also rotated, and in the same way, a second positioning rib is also moved, and centering is carried out. According to the device, when the diameter of a pipeline is small, the positioning ribs are enabled to synchronously move inwards for clamping by controlling the rotation direction of the bevel gears, two centering structures are arranged so that two sections of pipelines can becentered, the operation is convenient and rapid, and the accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a centering device for building pipelines based on the principle of synchronous motion. Background technique [0002] In the process of building construction or completing the construction, it is generally necessary for the corresponding professional inspectors to inspect the relevant buildings to check whether the construction complies with the relevant laws and regulations formulated by the state, mandatory standards for engineering construction, and construction drawings. Design documents, strictly control and check the quality of construction, so as to prevent imperfect and unreasonable construction projects. During the construction process, the detection of pipes and other tubular substances will also be involved. For example, pipes are in the construction process.

Problems solved by technology

[0002] In the process of building construction or completing the construction, it is generally necessary for the corresponding professional inspectors to inspect the relevant buildings to check whether the construction complies with the relevant laws and regulations formulated by the state, mandatory standards for engineering construction, and construction drawings. Design documents, strictly control and check the quality of construction, so as to prevent imperfect and unreasonable construction projects. During the construction process, the detection of pipes and other tubular substances will also be involved. For example, pipes are in the construction process. If several sections of pipelines are welded into one, the concentricity of the pipelines is also very important. In the existing technology, pads with the same height of the pipelines are generally raised to make the heights consistent, so as to maintain centering. During the operation, due to The pipe is generally round, so it is easy to be unstable when it is raised, causing shaking, and the error is large, which will increase inconvenience for subsequent operations, and subsequent re-welding will also waste costs

[0003] Aiming at the deficiencies of the prior art, the present invention provides a centering device for construction pipelines based on the principle of synchronous motion, which has the advantages of more convenient operation and more accurate centering, and solves the problem of large errors in the operation process
