Description

Technical Field

[0001] The utility model belongs to the technical field of elevator weighing alarm devices, and in particular relates to a vertical elevator rope head weighing device. Background Art

[0002] At present, there are two common solutions for vertical elevator rope head weighing devices:

[0003] Reference Figure 4 The first solution is to set up a double-layer rope head plate 71, and install a pressure sensor 72 between the double-layer rope head plates 71 to directly read the weighing data, or install rubber, and convert the rubber compression into the bridge compartment loading weight data. This solution requires the installation of a double-layer rope head plate 71, and the process is relatively complicated. If one piece is missed when installing the rope head or the pressure sensor 72 or the rubber needs to be replaced during maintenance, the cost of engineering rectification is high, and its replacement efficiency is low;

[0004] Reference Figure 5 The second solution is to directly install a flat plate 82 on the pull rod 81 of the rope head device, and then install the weighing switch 83 on the flat plate 82, and the trigger probe 84 is installed on the lower rope head plate 85 corresponding to the weighing switch 83. Although this solution is easy to install and maintain, since the weighing switch 83 is on one side of the rope head device, if the traction wire rope is unevenly stressed, the spring compression amounts on each rope head device will also be different, and there will be uncoordinated deformation, which may easily cause the upper flat plate 82 to appear irregularly tilted, affecting the contact detection of the weighing switch 83 on one side, thereby affecting the accuracy of the rope head weighing.

[0005] From the above, it can be seen that there is currently a lack of a new type of vertical elevator rope end weighing device, which can not only solve the convenience problems of device installation and maintenance, but also reduce the impact of weighing accuracy caused by uneven tension of the traction wire rope.
