Construction hoist with built-in balance weights

Abstract

The invention relates to a construction hoist with built-in balance weights. The construction hoist comprises hoisting cages, wheel carriers, the balance weights, guide frames and a wall attaching frame and further comprises winding assemblies, wherein steel wire ropes are wound on the wheel carriers, each balance weight is connected with one end of each steel wire rope, the wall attaching frame is fixed on the guide frames, each winding assembly is connected with the other end of each steel wire rope, the winding assemblies are connected with the hoisting cages, connecting devices which are connected with the balance weights are arranged on the steel wire ropes, connecting pieces which are matched with the connecting devices are arranged on the balance weights, a limiting device is arranged at the top of each balance weight, an interlocking assembly which enables a hoisting cage safety gate to be safely opened is arranged on each hoisting cage, and a protective door electromechanical interlocking device which enables a hoisting cage protective door to be normally opened is arranged on each hoisting cage. The construction hoist has the advantages that automatic collecting and releasing of the steel wire ropes can be achieved in the rising and section adding process through the winding assemblies, therefore, labor intensity of installation personnel is lowered, and safety performance of the equipment in the operation process is improved due to the fact that the interlocking assembly which enables the hoisting cage safety gate to be safely opened is arranged on each hoisting cage and the protective door electromechanical interlocking device which enables the hoisting cage protective door to be normally opened is arranged on each hoisting cage.

Description

technical field [0001] The invention relates to a construction hoist with built-in counterweight. Background technique [0002] The overall design and safety device configuration of the existing elevator do not meet the requirements of the newly promulgated GB26557-2011 "Construction Hoist with Vertical Guidance for Man and Cargo"; the overload protector can only realize instant alarm and has no memory function; If the counterweight wire rope breaks or falls off the groove, equipment and personal injury accidents will easily occur if the counterweight falls to the ground. Every time the joint is lifted, the steel wire rope must be manually threaded and pulled, which is time-consuming and laborious; the counterweight track is made of angle steel, and the assembly accuracy is poor. Derailment and jamming occurred, causing the wire rope to break and the counterweight to fall; the floor door was self-made by the user unit, which was likely to cause safety hazards and did not mee...
