The utility model is innovated again on the basis of the technology, and the main innovation point is to realize the automation of the whole moving function.
Disclosure of Invention
The utility model aims to: according to the actual situation of a construction site, the automatic Bailey beam moving device for integrally moving the cast-in-place beam is used for constructing a steel pipe upright base for a second span of a bridge while constructing a first span cast-in-place beam of the bridge, and after the first span cast-in-place beam is constructed, a moving button is started by one key, so that the Bailey beam support for the first span of the bridge can be automatically and integrally moved forwards to a position between piers of the second span. Therefore, the construction process that the support frame of the Bailey beam is dismantled in the first span and rebuilt in the second span can be reduced, the construction progress can be accelerated, the mechanical and manual investment can be reduced, the construction cost can be reduced, and the purpose of automatic overall movement can be achieved.
The utility model is realized by the following technical scheme:
a automatic mobile device of bailey beam for cast-in-place roof beam bulk movement, including support post, bailey beam, draw gear, its characterized in that: arranging a stand column base on a roadbed between a front bridge pier and a rear bridge pier, arranging a support stand column on the stand column base, arranging longitudinal I-shaped steel on the support stand column, laying a tetrafluoro sliding plate on the longitudinal I-shaped steel, erecting a Bailey beam on the tetrafluoro sliding plate, installing a vertical jack at the upper end of the Bailey beam, arranging a template joist on the vertical jack, and installing a cast-in-situ template on the template joist;
the lower end of the vertical jack is fixedly connected with the Bailey beam through a bolt, the upper end of the vertical jack is fixedly connected with the template joist through a bolt, and the template joist is flexibly connected with a cast-in-place template through a buckle;
a traction center-penetrating jack is arranged at one end of the Bailey beam, a traction fulcrum is arranged at the end head of one end of the longitudinal I-beam, and a displacement sensor is arranged on the traction fulcrum; a traction center-penetrating jack arranged at one end of the Bailey beam is connected with a traction fulcrum arranged on the end head at one end of the longitudinal I-beam through a traction connecting rod;
the vertical jack, the traction center-penetrating jack and the displacement sensor are respectively connected with a start button of the field control room.
The beneficial effects of the utility model are mainly shown in the following aspects:
the utility model provides an automatic Bailey beam moving device for integrally moving a cast-in-place beam, which is used for cast-in-place supports meeting the construction conditions of longitudinal span-by-span forward casting or left and right double-width simultaneous span-by-span forward casting.
The utility model can reduce the construction process of dismantling the first span and then rebuilding the Bailey beam support frame on the second span, thereby accelerating the construction progress, reducing the mechanical and manual investment and lowering the construction cost.
And thirdly, the vertical jack arranged at the upper end of the mine beam is started only by one key, so that the template joist at the upper end of the vertical jack and the cast-in-place template are integrally sunk, and the web bottom die is driven to automatically fall off.
According to the utility model, as long as the traction center-penetrating jack arranged at one end of the Bailey beam is started, the first span Bailey beam supporting frame reaches the position of the second span needing to be poured, and after the first span Bailey beam supporting frame touches the displacement sensor, the traction center-penetrating jack automatically stops traction operation, so that the purpose of automatic integral movement is realized.
