Problems solved by technology

When cross-working, if the cross-construction cannot be avoided and reliable isolation measures cannot be taken, it is impossible for the operator to concentrate on the construction or just pay attention to whether the hanging object passes above the head. Construction in such an environment will not only affect the construction period, but also It always poses a threat to the life safety of the operators under the hanging objects

Abstract

The invention discloses a cross operation display device for a tower type crane, which utilizes an image and a ring to avoid and remind a construction operator to avoid hoisting object damage. An alarm bell and a camera are installed on a hook roadster of the tower type crane, a steel wire rope is fixed between the outer end of a boom and a tower body through a bracket to be used for hanging a cable, and a supporting bracket is installed on the hook roadster to be used for supporting the steel wire rope as well as pushing and pulling the cable. When the crane operates, the electric bell ring and the camera can move along with the roadster to alarm the construction operators below a hoisting object to avoid a hoisting risk area, and a driver can adopt an avoidance measure in time to prevent the hoisting object damage when discovering a construction operator on a display. The invention is mainly used during hoisting work in the cross operation.

Description

(1) Technical field [0001] The invention relates to a display device for hoisting and hoisting operations, in particular, it can display whether a cross operator is in a hoisting and hoisting dangerous area. (2) Background technology [0002] At present, flat-arm tower cranes are generally used in construction projects, and the general work site must be covered by the flat arm of the crane. When the crane is hoisting, the hanging objects inevitably pass over the workers, especially the construction unit in order to meet the construction period. , During the construction process, it is impossible to stop the lifting and hoisting operation, and then carry out other constructions on the operation layer, and it is impossible to take protective isolation measures above the operation layer. In the case of cross-work, it is impossible to avoid cross-construction, and reliable isolation measures cannot be taken. It is impossible for the operators to concentrate on construction or ju...
