Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tensile testing equipment, in particular to a tensile testing and display device for a mine cable clamping plate. Background Technique
[0002] The cable clamping plate is an accessory of a mine shearer. According to the working needs of the shearer, it is connected into a protection channel for protecting the cable through a pin shaft or a bolt to prevent the cable from breaking and wearing. During the walking process of the shearer, the cable clamping plate moves back and forth under the traction force of the connection part of the shearer tail.
[0003] However, the bearing capacity of the cable clamping plate is limited. To prevent the cable clamping plate from breaking due to excessive tensile force during the walking process and damaging important facilities such as the power supply cable and ensure the normal operation of the shearer, a special tensile testing component is often set to detect the tensile force borne by the cable clamping plate.
[0004] The utility model patent with the publication number CN116979470A discloses a cable dragging device for a shearer, including a tensile testing component for detecting the tensile force applied by the cable clamping plate to the protection component and converting the detected tensile force into a tensile signal and transmitting it to the electric control system of the shearer. Although the above device can detect the tensile force by setting the tensile testing component, in actual use, additional installation work is required, and the structure of the component is relatively cumbersome, difficult to install, and inconvenient to replace the component, which will waste a lot of time. Moreover, it only sets a tensile sensor at one end of the cable clamping plate to detect the tensile force borne by the entire shearer. In actual use, when the shearer turns, the two ends of the cable clamping plate will bear different tensile forces. Therefore, only detecting the tensile force at one end, the result is not accurate and there will be potential safety hazards. Content of the Utility Model

The tensile sensor 5 and the clamping plate 6 are located on the plane where the front side of the side plate 4 is located. A connection hole 7 for connecting the cable clamp is arranged on the tensile sensor 5, and a fixing hole 8 for connecting the shearer is arranged on the clamping plate 6. This device can be connected as the last section of the cable clamp to the shearer, that is, connected between the cable clamp and the shearer. The usage method is simple and easy to understand, the installation and replacement are convenient, there is no need to install additional tension detection components, and it can accurately measure the tension borne at both ends of the cable clamp. Even when the shearer turns, accurate tension data can be obtained, which is safer and more standardized.
[0020] The tensile sensor 5 is electrically connected to a main control board 9. The main control board 9 is built into the clamp main body 1. The output end of the main control board 9 is connected to a display module 10 and an alarm module. The tensile sensor 5 directly measures the tension borne by the power supply cable clamp. The main control board 9 reads the data provided by the tensile sensor 5 and analyzes and processes it. The analysis and processing results will be displayed on the display module 10 in real time. If the analyzed and processed data is equal to or greater than the normal set value, the alarm module will give an alarm reminder.
[0021] It also includes a battery compartment 12 built into the upper bottom plate 2. The battery compartment 12 is provided with a power supply module for supplying power to the main control board. Open the battery compartment opening 13, and the built-in battery is used to provide electrical energy to ensure the normal operation of the device.
[0022] In another specific embodiment, the display module 10 is electrically connected to the main control board 9. The display module 10 is arranged on the side plate 4 of the clamping plate body 1. If the value obtained by the analysis and processing of the main control board 9 is less than the normal set value, the display module 10 has no response. If it is equal to or greater than the normal set value, the display module 10 will issue a voice or ringtone alarm for reminder, preventing the cable clamping plate from bearing excessive tension and ensuring the safe progress of the mining work.
