Description

technical field

[0001] The invention relates to a small machine tool for power transmission and transformation line construction, in particular to a motorized winch mill for traction and hoisting, and belongs to the technical field of motor winch mills. Background technique

[0002] In engineering construction, the line construction motorized winch is a frequently used tool, especially in field operations, the line construction motorized winch provides an indispensable external power for construction.

[0003] During engineering construction, traction equipment provides mechanical power through pull wires to help people complete the lifting and transfer of materials. Due to the large power provided by large and medium-sized traction equipment, in order to ensure the safety of the cable and prevent the cable from breaking due to overload, sensors are installed on the system to monitor the pulling force in time and stop working in time when the pulling force reaches and exceed...

Examples

Embodiment 1

[0031] like figure 1 , 2 As shown in , 3, an overload protection type intelligent winch includes a tension sensor 1, a display and measurement part 2, a switch, a setting control part 3, an equipment power supply part 4 and an electric starter motor body 5, the tension sensor 1 and the The main body of the electric starter motor is hinged, the tension sensor 1 is electrically connected with the display measuring part 2, the display measuring part 2 is electrically connected with the switch and the setting control part 3, the display measuring part 2 is electrically connected with the equipment power supply part 4, and the display measuring part is electrically connected 2. It is electrically connected to the main body 5 of the electric starter motorized winch, and the equipment power supply component 4 is electrically connected to the body 5 of the electric starter motorized winch. The equipment power supply part of the overload-protected intelligent winching mill supplies p...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that in this embodiment, the tension sensor component uses a strain gauge type tension sensor. The strain gauge type tension sensor has the advantages of high precision, wide measurement range, long life, simple structure, good frequency response characteristics, can work under harsh conditions, and is easy to achieve miniaturization, integration and variety diversification. Pull force measurement.

[0037] At the same time, in this embodiment, the display and measurement components of the overload-protected intelligent grinder are composed of a single-chip microcomputer and a liquid crystal screen.
