Problems solved by technology

[0005]In addition, the commonly used general motorized winch does not have other equipment to use power supply, so it does not use electric start but manual puller to start, long-term use of puller may cause pull The disk is damaged and cannot be started
[0006] The application date is December 30, 2009, the authorized announcement number is CN 201614245 U, and the name is "motorized winch machine with overload protection device" in China The invention patent discloses an overload protection device for tractor-type motorized winches. The motorized winch for which this invention is aimed is relatively large in size, and the braking method is mainly for diesel engines. The braking design is to use a DC motor to pull the cable to make it The way of separating the clutch belt pulley has not been improved correspondingly for the small motorized winch with gasoline engine as the engine commonly used in the field. Small motorized winch generally adopts direct shaft transmission and does not use a belt pulley, so its braking method cannot For small motorized winches
At the same time, the invention does not consider the requirement of charging the power supply in the field, which limits the long-term continuous field application of the device.
[0007] The application date is November 18, 2009, the authorized announcement number is CN 201545644 U, and the Chinese invention patent named "a hydraulic winch mill" is published A hydraulic winch mill has been developed. Although the winch mill has the functions of tension measurement and overload protection, it is different from the transmission type of the currently widely used motorized winch mill. motorized winch

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.

Abstract

The invention discloses an overload protection type intelligent twisting and grinding machine, which comprises a tension sensor component, a display measurement component, a switch, a setting control component, an equipment power supply component and an electric starting maneuvering twisting and grinding body. The overload protection type intelligent twisting and grinding machine disclosed by the invention has the advantages of small size, simple construction and convenience in installation and is suitable for the safe monitoring of a small maneuvering twisting and grinding machine for the line construction, and the stressing situation of traction equipment can be visually reflected. When a working load exceeds a set load, the overload protection type intelligent twisting and grinding machine can automatically stop operating, and the requirement of safe construction is achieved. The equipment can be electrically started, and an engine can charge a power supply during operation.

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...
