Description

Telescopic crane landing leg straightness measuring rod that hangs down Technical Field The utility model relates to a telescopic crane landing leg verticality detection rod, and belongs to the technical field of crane auxiliary detection equipment. Background At present, the crane is widely applied in the fields of building construction, cargo handling and the like, the verticality of the supporting legs is critical to the safe and stable operation of the crane, the inclined and swaying of the crane can be caused in the operation process due to the poor verticality of the supporting legs, even serious safety accidents are caused, and casualties and property loss are caused. The traditional method for detecting the verticality of the crane landing leg usually needs to rely on manual measurement by using simple tools such as plumb lines, square and the like, but the method is low in efficiency, the measurement accuracy is easily affected by human factors, and the quick multi-angle rotation detection after fixing cannot be realized, so that the method has limitations. Therefore, in order to solve the above problems, it is needed to design a new detecting rod for detecting the verticality of the crane leg. Disclosure of utility model In order to solve the problems, the utility model provides the telescopic crane landing leg verticality detection rod which is simple in structure, convenient to operate and high in detection efficiency and can realize multi-angle rotation detection. The utility model relates to a telescopic crane landing leg verticality detection rod, which comprises The main rod mechanism consists of a main rod and an outer tube, wherein the main rod is sleeved in the outer tube in a sliding way, the upper end of the main rod extends to the outside of the outer tube, the main rod is sleeved in the outer tube, and the main rod can be pulled in the outer tube in a sliding way to form a telescopic structure; The rotary block is rotationally connected with the main rod through a rotary shaft, and two sides of the rotary block are fixedly connected with scale plates with arc structures; the device comprises a rotating block, a connecting plate, a rotating shaft, a connecting plate and a connecting plate, wherein one end of the connecting plate is rotationally connected with the rotating block through the rotating shaft; The clamping assembly consists of two clamping parts which are symmetrically arranged, one end of each clamping part is fixedly connected with the connecting block, the other end of each clamping part is fixedly connected with a side plate with a side U-shaped structure, the inner side of each side plate is rotationally connected with a splicing block, each splicing block is provided with a limiting hole, and the clamping assembly can be limited by installing bolts in the limiting holes of the corresponding splicing blocks. Further, a limiting ring for preventing the main rod from being separated is fixedly arranged in the outer tube. Furthermore, the bottom of the outer tube is also fixed with a balancing weight, and the balancing weight is arranged at the bottom of the outer tube, so that the main rod mechanism can be kept in a vertical state more stably.
