Road and bridge crack repairing and fixing structure
The invention belongs to the technical field of road and bridge repair, and discloses a road and bridge crack repair fixing structure which comprises an outer box and a road body, a cylindrical cam is movably connected to the interior of the outer box, and guide grooves are annularly formed in the inner wall of the cylindrical cam by 180 degrees. Through cooperation of a cylindrical cam, a push rod, a second connecting rod and other structures, the device has the effect of preventing the crack from expanding and affecting the repairing process, the push rod slides in a spring when moving downwards, so that the cylindrical cam and the first connecting rod below the cylindrical cam are driven to rotate, and two limiting blocks are driven to move oppositely through the second connecting rod and a third connecting rod; the two limiting rods are driven to move to the positions above the holes of the road body, the limiting rods are clamped into the holes, then pressing on the push rods is released, at the moment, the two limiting blocks generate pulling force through the tension spring rods, the limiting rods are driven to generate pulling force on the two sides of the crack, and then the crack is prevented from being expanded.
本发明属于道路桥梁修复技术领域，且公开了一种道路桥梁裂缝修复固定结构，包括外箱和道路本体，所述外箱的内部活动连接有圆柱凸轮，所述圆柱凸轮的内壁环形等一百八十度开设有引导槽。通过圆柱凸轮、推杆和第二连杆等结构之间的配合，使得装置具有防止裂缝处扩大，影响修复进程的作用，通过推杆下移时在弹簧的内部滑动，从而带动圆柱凸轮和其下的第一连杆旋转，通过第二连杆和第三连杆带动两个限位块相反移动，从而带动两个限位杆分别移动至道路本体孔洞的上方，限位杆卡入孔洞内部，随后松开对推杆的按压，这时两个限位块通过拉簧杆产生拉力，从而带动限位杆对裂缝处的两侧产生拉力，进而防止裂缝处扩大。
