Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] figure 1 Shown is the weight sensor used to measure the load of the steel wire rope. In the prior art, the weight sensor is installed at the pin shaft position of the pulley of the hoisting machine and used as the pulley pin shaft. The structure is relatively complicated and there is no shaft broken protection. exist figure 1 In the structure shown, the force on the pulley is relatively large, so the size of the weight sensor used as the pin shaft of the pulley is required to be large; the force on the pulley is not a constant value, resulting in a large error in the value measured by the w...

The invention discloses a steel wire rope clamping device used for measuring a load of a steel wire rope. The steel wire rope clamping device comprises a weight sensor, a wire clamping plate and a broken shaft protector, wherein one end of the weight sensor is connected with the broken shaft protector and the other end of the weight sensor is connected with the wire clamping plate; the broken shaft protector comprises a reserved pin shaft; and when the weight sensor is fractured by fatigues, the reserved pin shaft has a protection effect as a replaced connection shaft. The steel wire rope clamping device has a simple structure; integration and modularization are realized; and the steel wire rope clamping device has parts with small size, is convenient to mount and maintain, has high measurement precision, and has relatively good reliability and economical efficiency.
Description
technical field [0001] The invention relates to the field of hoisting machinery, in particular to a wire rope clamping device for measuring the load of a wire rope. Background technique [0002] At present, the hoisting machinery in the port generally adopts the form that the weight sensor and the rope clamping plate are respectively installed at different positions of the same system. Bolt connection with single or double friction. The weight sensor and the rope clamping plate are installed in different positions and need to be maintained separately; when the weight sensor doubles as the pin shaft of the pulley, the structure is more complicated and there is no shaft breaking protection; The force on the pulley is not a constant value, resulting in a large error in the value obtained by the weight sensor. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a wire rope clamping device for measuring the load ...
