Embodiment Construction

[0028] In this embodiment, in order to provide the stability of the support rod 11, as figure 1 As shown, preferably, the bottom end of the support rod 11 is provided with a support base 13 for mounting on the flange plate 91 . Further preferably, the support base 13 is connected to the bottom end of the support rod 11 in a rotatable manner, and is used to adjust the inclination angle of the bottom wall of the support base 13 so that the inclination angle between the support base 13 and the flange plate 91 To further improve the stability of the support rod 11. In this embodiment, the support base 13 can be connected with the support rod 11 through the spherical joint 14 , so that the support base 13 can be driven to rotate through the spherical joint 14 .

[0029] continue to see Figure 4 to Figure 6 , in this embodiment, the first mechanical arm 5 includes: a telescopic arm 51 in the first direction and a telescopic arm 52 in the second direction; wherein the telescopic a...

Abstract

The invention provides a pre-stressed concrete box girder web bush hammer. The pre-stressed concrete box girder web bush hammer comprises a supporting frame; the moving mechanism can move on the supporting frame; the length adjusting mechanism is arranged below the moving mechanism; the case is arranged below the length adjusting mechanism, and the case is connected with the length adjusting mechanism through the rotating mechanism; the connecting end of the first mechanical arm is arranged on the machine box, a milling and planing tool is arranged at the supporting end of the first mechanical arm, and the connecting end of the milling and planing tool is rotatably connected with the first mechanical arm; the connecting end of the second mechanical arm is arranged on the machine box, and the supporting end of the second mechanical arm is provided with a fixing mechanism. Through telescoping and swinging of the rotating mechanism, the moving mechanism, the first mechanical arm and / or the second telescopic arm, the chiseling device can adapt to most prestressed concrete box girder structures, the chiseling construction process can be accelerated, the bonding strength of new concrete and old concrete is improved, the construction efficiency is improved, and the construction cost is reduced. And concrete fragments generated during chiseling work and pollution to the environment in the chiseling work process are reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prestressed concrete box girder web chipping machine. Background technique [0002] In recent years, with the rapid development of transportation, prestressed bridge engineering is the most widely used at this stage. Secondary pouring is often used when pouring prestressed concrete box girders. The advantage is that the beam formed by the first pouring of concrete is used to support the self-weight and construction load of the second pouring concrete, increasing the safety of the support; the inner formwork is installed and reinforced to directly support To the beam floor, increase the stability; reduce a large number of formwork support materials; the corresponding measures are less costly, and at the same time, because the concrete layered pouring can alleviate the adverse effects of large-volume hydration heat and temperature stress on crack control, horizontal...
