technical field

The invention relates to the field of bridge construction equipment, and specifically discloses a climbing box and a driving device for a climbing formwork.

Background technique

Existing climbing boxes generally include climbing frames, wall-attaching devices, climbing boxes and slide rails. The wall-attaching device is used to attach to the building structure, such as bridge piers, etc.; the climbing frame generally includes upper beams, lower beams, columns and diagonal struts. The upper beam and the lower beam, the diagonal struts are inclined and the upper and lower ends are connected with the upper beam and the lower beam respectively. The function of the climbing frame is to install the template; the climbing box slides on the slide rail and moves along the slide rail, climbing The box drives the climbing frame to move upward to realize the function of the template climbing upwards. The slide rail not only guides the climbing box but also bears the component force of the climbing frame in the horizontal direction. Climbing boxes of this type of structure all climb on one side. When the climbing form on one side falls, it is easy to cause potential safety hazards. At present, there have been climbing forms that connect multiple surfaces to form a whole for climbing, but they use booms and through-core jacks. Due to the insufficient strength of booms, this structure can only carry a relatively small weight for climbing. box.
