The invention provides an elevator load alarm detection device which comprises a loading beam frame, a force measuring assembly, a force transferring assembly, a power assembly and a transmission assembly. The power assembly is fixedly connected to the loading beam frame and pushes the force measuring assembly to move through the transmission assembly, the force measuring assembly is connected with the force transferring assembly, and the force transferring assembly moves along with the force measuring assembly so as to be loaded on an elevator rope hitch plate fixed to the loading beam frame. The elevator load alarm detection device has the advantages that a traditional weight loading method through an elevator cab is replaced by a weight loading method through a motor, work efficiency of testing is improved, and labor intensity is reduced; in addition, the elevator load alarm detection device can be applied to different elevator rope hitch plates thanks to rotational joints of the loading beam frame and adjustable pressure of the force transferring assembly; the structure that a spring is indirectly connected with a force sensor is arranged aiming at the force measuring assembly, so the operating distance of force is increased, demands for lead screw accuracy are reduced, meanwhile, rigidity contact among the assemblies is avoided, product cost is lowered, and reliability is improved.
Description
technical field [0001] The invention belongs to the technical field of safety detection, relates to the load detection of an elevator car rope head plate, and in particular relates to a detection device for an elevator load alarm which is convenient for loading. Background technique [0002] The elevator rope end plate is an important force bearing device for the elevator car. In order to ensure the safe operation of the elevator, an alarm device is set for the force of the elevator rope end plate to prevent accidents caused by overload operation. [0003] In order to supervise the safety of elevators and other devices and prevent public safety accidents caused by elevator failures, technical supervision departments or corresponding organizations will regularly test the safety indicators of elevators. Among them, the detection of the load alarm of the rope head plate used to carry the elevator car is an important content. The detection process is to pressurize the elevator ...
