Description

Ultra-wide sliding mode joint cutter Technical Field The utility model relates to the technical field of auxiliary engineering slip form construction, in particular to an ultra-wide slip form joint cutter. Background The cast-in-situ slip form construction is an important point and a difficult point of the construction of the auxiliary engineering, and whether the construction process is rapid and the quality is guaranteed directly influences the construction period and the construction quality of the whole auxiliary engineering and influences the opening time of the whole engineering. The traditional construction method adopts manual joint cutting, so that the requirements of engineering on speed and efficiency are far not met, the method is low in efficiency, the whole auxiliary construction progress is seriously influenced, the appearance is uneven, and the appearance and quality are seriously influenced, if the joint cutting machine is adopted for joint cutting, concrete needs to be solidified, and joint cutting operation is carried out, but because the traditional joint cutting machine is used for cutting a shallow dish-shaped side ditch, the whole device needs to enter the shallow dish-shaped side ditch, and radian is arranged in the shallow dish-shaped side ditch, the shallow dish-shaped side ditch cannot be stably cut. Disclosure of utility model In view of the above, the present utility model provides an ultra-wide slip form slitting machine that solves or at least alleviates the above-identified problems of the prior art. In order to achieve the above object, the present utility model provides an ultra-wide sliding mode cutting and sewing machine, comprising: the vehicle frame comprises wheels capable of walking on the ground, and the vehicle frame can swing up and down by taking the wheels as fulcrums; the saw blade is arranged at the front end of the frame, and can be inserted into the ground through downward swing of the front end of the frame, so that the slitting operation is realized; The limiting structure is arranged at the front end of the frame, and can support the front end of the frame at different heights, so that the cutting depth of the saw blade is controlled. In one ultra-wide sliding mode joint cutter as described above, optionally, the limiting structure is a lifting rod, and can be displaced in a height direction of the frame. In the above ultra-wide sliding mode joint cutter, optionally, the limiting structure is a stop shoe, which is located at the outer side of the saw blade and can swing around the center of the saw blade as the center of a circle. In the ultra-wide sliding mode joint cutter as described above, optionally, the retaining shoe is located at the rear side of the saw blade, a groove is formed in a side surface of the retaining shoe, which is close to the saw blade, baffles are fixedly mounted at the bottom ends of two sides of the retaining shoe, and the front end of the baffle is rotatably sleeved at the center of the saw blade.
