Mounting and lifting system of movable formwork for bridge construction

WANG LIMIN

The invention discloses an installation and lifting system of a movable formwork for bridge construction. The installation and lifting system structurally comprises a first horizontal moving supporting device, a moving module, a second horizontal moving supporting device, a top plate, a lifting device, a bottom plate and a moving fixing device; and a bottom plate is fixed to the top of the movablefixing device, and the bottom plate is connected with the top plate through a lifting device. Compared with the prior art, the beneficial effects of the invention are that: the fixed adsorption device shares the weight of the equipment by utilizing contact with the contact surface and shares the gravity for moving wheels, so all gravity is prevented from being applied to the moving wheels; the equipment placement stability is improved by utilizing the adhesive force between the equipment and the ground through the sucking discs; and the moving wheels are limited by the moving wheel limiting clamping cover through descending of the plate body, the moving wheels are prevented from sliding and being damaged, the moving wheels do not need to be unlocked one by one, the operation is simpler and more convenient, the moving formwork can translate through the nut pair and the two-way lead screw to conduct fine transverse horizontal movement, and the precision of bridge construction can be greatly improved.

本发明公开了一种桥梁施工用移动模架的安装提升系统，其结构包括有一号水平移动支撑装置、移动模块、二号水平移动支撑装置、顶板、提升装置、底板、移动固定装置，移动固定装置顶部固定有底板，底板通过提升装置与顶板相连接，与现有技术相比，本发明的有益效果在于：通过固定吸附装置利用与接触面接触来分担设备的重量，为移动轮分担重力，避免重力全部施加于移动轮，利用吸盘更加设备与地面的附着力来提供设备放置的稳固性，通过板体的下降使移动轮限位卡罩对移动轮进行限位，防止移动轮发生滑动，避免移动轮受损，无须一个一个去锁移动轮，更为简便，通过螺母副与双向丝杆使移动模板得以平移进行细微横向水平移动，能大大提高桥梁施工的精度。
