Problems solved by technology

[0002] At present, the installation height of the longitudinal guide rail of the vertical gear climbing large ship lift is large, the installation space is small, the structural rigidity is small, and the overall installation accuracy is high. The auxiliary installation tooling with hydraulic telescopic adjustment function processed by large precision machine tools is usually used. Equipment, this kind of auxiliary equipment has complex structure, long construction period, high cost and great difficulty in construction. For the longitudinal guide rails arranged on the convex wall of the Three Gorges vertical ship lift with a total installation height of more than 120m, it is not very good. It can effectively solve the problem of easy deformation due to its small structural rigidity in the process of transportation and hoisting, and it is also difficult to meet the technical requirements of high-precision installation

Embodiment Construction

[0027] A method for installing a longitudinal guide rail, comprising the following steps:

[0028] 1) Concrete convex wall 10 is poured, and anchor plate embedded parts 6 are pre-embedded on both sides of poured concrete convex wall 10, which are used for the fixed installation of "U"-shaped steel beam frame;

[0029] 2) Hoist the "U"-shaped steel beam frame and connect it with the embedded part 6 of the anchor plate, and connect the built-in steel frame 1,1' and the longitudinal guide rails 9,9' through the fixing bolts 102 on the pre-assembled platform; specifically, the built-in steel frame The auxiliary steel frame 103 in 1, 1' is connected with the guide rail working panel 91 in the longitudinal guide rails 9, 9' through fixing bolts 102, in order to ensure the accuracy, there is also a spacer between the auxiliary steel frame 103 and the guide rail working panel 91 101, the mating surface of the spacer 101 and the guide rail working panel 91 is machined to improve flatn...

Abstract

The invention provides a method and device for installing a longitudinal guide rail. A U-shaped steel beam frame is adopted as a rigid support and is of a stronger-rigidity integral structure formed by a longitudinal strut, a transverse strut and an inclined strut, and the U-shaped steel beam is temporarily welded and connected with an anchor plate embedded cluster on a concrete convex wall to form a rigid structure with the stronger rigidity, thus the installation regulation and fixation of the longitudinal guide rail can be convenient, and the high-precision requirement of the longitudinal guide rail is met. A built-in steel frame is connected with the longitudinal guide rail into a whole, thus the rigidity is increased and the rigidity requirements of the transportation and the hoisting are met. The method and device in the invention can be especially suitable for the installation construction of the longitudinal guide rail of a vertical tooth-climbing vessel-lifting motor vessel with the large total installation height, the low structure rigidity and the high installation precision, and other similar installation construction projects.

Description

technical field [0001] The invention relates to a construction method and device for pre-embedding a longitudinal guide rail into concrete, in particular to a method and device for installing a longitudinal guide rail with a large overall installation height, low structural rigidity and high requirements for overall installation accuracy. Background technique [0002] At present, the installation height of the longitudinal guide rail of the vertical gear climbing large ship lift is large, the installation space is small, the structural rigidity is small, and the overall installation accuracy is high. The auxiliary installation tooling with hydraulic telescopic adjustment function processed by large precision machine tools is usually used. Equipment, this kind of auxiliary equipment has complex structure, long construction period, high cost and great difficulty in construction. For the vertical guide rails of the ship compartment arranged on the convex wall with a total instal...
