Description

Technical Field

[0001] The present application belongs to the technical field of equipment maintenance, and in particular, relates to a pull-cord switch status display device. Background Art

[0002] Before performing maintenance work near a belt conveyor, maintenance personnel must take relevant safety measures, including using a pull cord. After completing their work, they must reset the pull cord switch and notify the control center to evacuate the site. However, sometimes, due to external forces or environmental factors, the pull cord switch cannot be fully reset, causing the belt conveyor to remain in the pull cord state. In this case, the control center dispatcher will contact on-site inspection personnel and electricians to conduct on-site troubleshooting. However, in practice, inspection personnel and power maintenance personnel cannot intuitively determine the pull cord status and can only rely on their experience to troubleshoot, which is inefficient. This phenomenon affects the time it takes for the control center to start the equipment, reducing production efficiency. Utility Model Content

[0014] The correspondence between the reference numerals and component names is as follows:

[0015] Sensor-10, alarm-20, first base-30, second base-40, pull cord switch-100, pull rod-101, tape holder-200. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0017] Before describing the various embodiments of the present application in detail, the technical concept of the present application will be briefly described: Currently, when performing maintenance work near a belt conveyor, workers are required to conduct on-site inspections to troubleshoot the reset status of a pull-cord switch, which affects production efficiency. To this end, the present application provides a pull-cord switch status display device that utilizes a position sensor to detect the position of the pull rod of the pull-cord switch. When the pull rod is not in the reset position, an electrical signal is generated. Upon receiving the electrical signal, an alarm generates an alarm signal, allowing workers to intuitively, conveniently, and quickly accurately locate a pull-cord switch that has not been reset. The specific principles of the pull-cord switch status display device of the present application will be described below in conjunction with more embodiments.

[0018] Specifically, if Figure 1 As shown, a pull-wire switch status display device of this embodiment includes a position sensor 10 and an alarm 20. The position sensor 10 is used to be installed at a corresponding position of the pull-wire switch 100, and the position sensor is used to detect the position of the pull rod of the pull-wire switch 100 and generate an electrical signal when it detects that the pull rod 101 is not in the reset position. The alarm 20 is connected to the position sensor 10, and the alarm 20 is used to generate an alarm signal when it receives the electrical signal emitted by the position sensor 10.

[0019] In one or more embodiments, the pull-cord switch status display device further includes a first base 30, which is configured to be mounted between the pull-cord switch 100 and the tape dispenser bracket. The position sensor 10 is mounted on the first base 30, and the position sensor 10 is directly opposite the pull rod 101. Exemplarily, the position sensor 10 is a proximity sensor. When the proximity sensor senses that the pull rod 101 is in the reset position, no electrical signal is generated, indicating that the pull-cord switch 100 has been fully reset. When the proximity sensor senses that the pull rod 101 is not in the reset position, an electrical signal is generated, indicating that the pull-cord switch 100 has not been fully reset and that an alarm 20 is required to alert personnel.

[0020] In one or more embodiments, the pull-cord switch status display device further includes a second base 40, which is mounted on the first base 30, and an alarm 20 is mounted on the second base 40. The alarm 20 is an audible and visual alarm, which is configured to generate an audible and visual alarm signal upon receiving an electrical signal from the position sensor, thereby facilitating a worker to quickly determine that the switch has not been reset to its full position through the alarm sound and light signal.

[0021] Exemplarily, the first base 30 , the second base 40 and the pull-cord switch 100 are all mounted on the tape holder 200 .

[0022] The pull-cord switch status display device provided in this embodiment can timely and intuitively detect a pull-cord switch that has not been reset to its original position through the cooperation of a position sensor and an alarm, thereby improving the work efficiency of inspection personnel and avoiding wasting startup time due to searching for the pull-cord switch; and can also allow on-site personnel to intuitively see the status of the belt conveyor's pull-cord safety measures, reminding the operator that the belt conveyor's pull-cord has been hung.

[0023] The above describes in detail the specific implementation methods of the present application. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principles and spirit of the present application, the scope of which is defined by the claims and their equivalents. These modifications and improvements should also be within the scope of protection of the present application.
