Laser fine-adjustment device for installing and positioning anchorage prestressing steel pipe

Abstract

The invention discloses a laser fine-adjustment device for installing and positioning an anchorage prestressing steel pipe. The laser fine-adjustment device comprise a starting device for fixing a laser pen and performing angle adjustment, a fixing support for fixing the prestressing steel pipe and a receiving device. The starting device arranges the laser pen at one end of the prestressing steel pipe, the receiving device is arranged at the other end of the prestressing steel pipe and used for receiving laser penetrating through one end of the prestressing steel pipe and emitted out of the other end of the prestressing steel pipe, a fine-adjustment device is close to one side of the receiving device and arranged on the fixing support and comprises a U-shaped sliding bracket arranged at the lower portion of the prestressing steel pipe and adjusting screws arranged at the bottom and the left and right sides of the prestressing steel pipe respectively and used for adjusting displacement of the prestressing steel pipe. The laser fine-adjustment device can achieve rapid installation and reliable positioning and is simple in structure, low in device machining and manufacturing cost and good in reliability.

Description

technical field [0001] The invention relates to a laser positioning device, in particular to a laser fine-tuning device for installation and positioning of an anchor prestressed steel pipe. Background technique [0002] In the acceptance system of the suspension bridge, the force of the bridge is mainly transmitted to the anchor block through the main cable, and the anchor uses its own weight to balance the force of the bridge; therefore, the construction of the anchorage system is the key to the construction of the entire suspension bridge; the anchorage system of the main cable of the suspension bridge is anchored by strands It is composed of tie rod structure and prestressed steel beam anchorage structure; one end of the tie rod is connected to the anchor plate on the anchor head of the cable strand at the front anchorage surface; the prestressed steel beam anchorage system structure is composed of prestressed steel beam and anchorage The pipeline is buried in the anchor ...

[0002] In the acceptance system of the suspension bridge, the force of the bridge is mainly transmitted to the anchor block through the main cable, and the anchor uses its own weight to balance the force of the bridge; therefore, the construction of the anchorage system is the key to the construction of the entire suspension bridge; the anchorage system of the main cable of the suspension bridge is anchored by strands It is composed of tie rod structure and prestressed steel beam anchorage structure; one end of the tie rod is connected to the anchor plate on the anchor head of the cable strand at the front anchorage surface; the prestressed steel beam anchorage system structure is composed of prestressed steel beam and anchorage The pipeline is buried in the anchor block; the positioning of the prestressed steel pipe is a core link in the construction of the anchor body, and its installation accuracy is very high. During the construction process, the pipeline must not be deformed or leaked, so that the prestressed steel beam can pass through smoothly; The traditional construction technology is mainly through the measurement and accurate lofting, marking, strengthening the prestressed steel pipe, and then performing measurement review or repositioning reinforcement; this method has a large workload of construction measurement and lofting, and there is a process of repeated verification and reinforcement; resulting in low productivity of manual work , which greatly increased the construction cost, and at the same time, the construction accuracy process could not be guaranteed, which seriously affected the construction progress
