Embodiment Construction

[0025] The device and method for erecting the track beam of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0026] combine figure 1 and figure 2 , an erecting device for a track beam, comprising: a first top frame 10 arranged at the end of a track beam 1 installed in place; a second top frame 20 arranged at an end of a track beam 2 to be installed, and the second top frame The frame 20 is offset against the first top frame 10 . The second top frame 20 moves away from the first top frame 10 under the push of the hydraulic jack 3 of the first top frame 10 , thereby ...

Abstract

The invention discloses a track beam setting up device and method, and belongs to the technical field of elevated and bridge construction, in order to solve the problem of poor positioning accuracy of track beam lifting. The device comprises a first upper frame and a second upper frame, wherein the first upper frame is arranged at the end of a track beam already mounted in place, and the second upper frame is arranged at the end of a to-be-mounted track beam and is butted against the first upper frame. The second upper frame drives the to-be-mounted track beam to move towards the direction away from the first upper frame under pushing of a hydraulic jack of the first upper frame. The method includes: lifting the to-be-mounted track beam to a place through a large-sized crane, controlling the spacing between the to-be-mounted track beam and the track beam already mounted in place to be 30mm</=d<50mm, then mounting the first upper frame, the second upper frame and the hydraulic jack, when a lifting hook is not loosened completely, starting the hydraulic jack to push the second upper frame to drive the to-be-mounted track beam to move, measuring d manually, and stopping the hydraulic jack when d=50mm. The device is high in mounting and positioning accuracy, convenient to operate, simple in structure and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of viaduct and bridge construction, and in particular relates to a track beam erecting device and a method thereof. Background technique [0002] The track beam is a concrete structure, and usually the weight of the track beam reaches 200 tons. When installing the track beam, it is necessary to adopt a large hoisting machine to hoist the track beam to the support on the top of the column. According to the installation specification, the gap width between two adjacent track beams in the horizontal direction is 50mm. In order to make the hoisting and positioning of the track beams accurate, the usual method is, before hoisting the track beams to be installed, use a wooden board to cushion the end face of the installed track beams, the thickness of which is 50mm. After the track beam to be installed is hoisted in place, the track beam to be installed is slowly placed on the support with a crane, and the end f...
