Description

Technical Field

[0001] The invention relates to the technical field of track bolt positioning and installation, in particular to a track bolt positioning and installation method. Background Art

[0002] In the current steel mill construction, the track foundation in the plant is pre-buried with bolts. The biggest construction difficulty of pre-buried bolts is to ensure the installation accuracy of the bolts. The conventional construction practice is that each bolt needs to be positioned when installed, and the positioning and fixing of the bolts are carried out on the steel bars that have been tied to the concrete foundation. The operation position and operation sequence are limited, and the efficiency is low. In addition, the positioning process is cumbersome and repetitive, requiring a lot of manpower, material resources and time, and it is difficult to ensure the position accuracy of the bolts. Summary of the invention

[0003] The present invention aims to solve the above-mentioned problem, thereby providing a method for positioning and installing a track bolt.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution: The positioning and installation method of the rail bolts shall be carried out in the following steps: Step 1: Carry out conventional concrete foundation reinforcement tying; Step 2: Determine the installation position of the track bolts according to the track foundation construction drawings; Step 3: An adjustable bolt fixing assembly is arranged above the determined rail bolt installation position, and the bolt fixing assembly is fixed to the underlying steel bar below. After the rail bolt is installed on the bolt fixing assembly, the position can be adjusted through the bolt fixing assembly; Step 4: Fine-tune the position of the rail bolts using the bolt fixing assembly, and secure them with nuts after adjustment; Step 5: Pour concrete to complete the positioning and installation of the track bolts.

[0005] Furthermore, the bolt fixing assembly includes four angle steels, which are arranged in pairs parallel to the length direction of the track to be installed. A gap is left between the two angle steels in each pair according to the diameter of the track bolt. The distance between the two pairs of angle steels is determined according to the spacing between the two ends of the U-shaped track bolt, so that the two ends of the U-shaped track bolt can respectively pass upward from the gap between each pair of angle steels. Support angle steels are arranged below the four angle steels, and the support angle steels are welded and fixed to the foundation steel bars below.

[0006] Furthermore, a bolt positioning plate is arranged between the two pairs of angle steels, and the two sides of the bolt positioning plate are respectively placed on top of two angle steels adjacent to the two pairs of angle steels, and the side edges are located between the gaps of each pair of angle steels. At least two pairs of bayonet slots are opened on the opposite side edges of the bolt positioning plate for limiting the bolt rod of the rail bolt.

[0007] Furthermore, the spacing between adjacent bayonet holes is determined according to the spacing between two adjacent track bolts.

[0008] Furthermore, in step 4, while the track bolt is fixed with a nut, the end of the track bolt is adjusted to the designed elevation.

[0009] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: The rail bolt positioning and installation method described in the present invention can effectively improve the construction speed, save labor costs, and improve the construction quality; by welding the bolt fixing assembly above the determined rail bolt installation position, and then fine-tuning the position of the rail bolt through the bolt fixing assembly, the rail bolt can be installed in place quickly and accurately, thereby improving the construction speed, saving construction costs, and being simple to operate and convenient to construct.
