Description

Technical Field

[0001] This utility model relates to the field of engineering machinery safety monitoring technology, and in particular to an early identification and warning device for mechanical equipment failure hazards at construction sites. Background Technology

[0002] Construction site machinery and equipment refers to various mechanical devices used in the construction process, mainly for material handling, processing, hoisting and other operations.

[0003] In construction sites, cables in mechanical equipment are an indispensable part of transmitting energy and information between and between different pieces of equipment. However, in harsh working environments, cables are prone to being pulled and twisted, causing localized tears on their surfaces. If these tears are not detected and repaired in time, they can eventually break unexpectedly, leading to electrical leaks, accidents, and economic losses. Currently, cable fault identification and detection mainly involves workers using handheld fault identification devices to scan the outside of the cable. When tears are detected, an alarm is triggered. However, during use at construction sites, cables inevitably accumulate dust on their surfaces, making it difficult for fault identification devices to accurately identify them. This can cause some tears to be missed, leaving potential safety hazards. Utility Model Content

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figure 1-4A device for early identification and warning of mechanical equipment malfunctions at construction sites includes a fixing component a1 and a fixing component b2. A hinge 18 is provided between fixing component a1 and fixing component b2. Fixing component b2 is rotatably connected to the upper part of fixing component a1 via the hinge 18. An upper cleaning roller 3 is provided inside fixing component b2, and a lower cleaning roller 4 is provided inside fixing component a1. Fixing grooves 10 are provided on both sides of the inner walls of fixing component b2 and fixing component a1. Limiting rods 14 are fixedly connected inside the fixing grooves 10. Sliding blocks 15 are slidably connected to the outer side of each limiting rod 14. The lower cleaning roller 4 is rotatably connected between two of the sliding blocks 15, and the upper cleaning roller 3 is rotatably connected between the other two sliding blocks 15. Springs are sleeved on the outer side of each limiting rod 14 and on one side of each sliding block 15. 16. When using this equipment to inspect equipment cables at the construction site, the fasteners a1 and b2 are connected together by using hinge 18 so that the equipment cable is placed between the fasteners a1 and b2. As the fasteners a1 and b2 move as a whole, the dust adhering to the outer wall of the cable is cleaned by the upper cleaning roller 3 and the lower cleaning roller 4, thereby ensuring the identification accuracy of the fault identification device 6 and avoiding detection omissions. At the same time, the upper cleaning roller 3 and the lower cleaning roller 4 can be pushed towards the center by the action of spring 16 so that the upper cleaning roller 3 and the lower cleaning roller 4 can always be in contact with the surface of the cable to improve the cleaning effect of dust. Moreover, the above structure can be applied to the cleaning of cables of different sizes and has a wide range of applications.

[0028] Specifically, a detection component is provided at the bottom of the fixing component a1. The detection component includes a mounting bracket 5 fixedly connected to the bottom of the fixing component a1. By moving the fixing component a1 as a whole, the fault identification device 6 can be driven to detect the cable, thereby completing the early fault identification process of the cable and making the cable detection process more efficient. The fault identification device 6 is provided inside the mounting bracket 5, and a fixing component is provided inside the mounting bracket 5. The fixing component includes two threaded rods 12 threadedly connected inside the mounting bracket 5. By rotating the threaded rods 12, the contact plate 13 can be driven to slowly approach. The fault identification device 6 is installed with the aid of the contact plate 13. This also facilitates the removal of the fault identification device 6 from the mounting frame 5 for inspection and maintenance. One end of the threaded rod 12 is fixedly connected to the contact plate 13. One side of the fixing part a1 and the fixing part b2 are fixedly connected to the semi-threaded post 8. The two semi-threaded posts 8 are threaded together with the locking nut 9. By using the semi-threaded post 8 and the locking nut 9 together, the fixing part b2 and the fixing part a1 can be fixed, so that the cable is more stable during the detection process and is not easy to slip out.

[0029] Specifically, the spring 16 is set between the inner wall of the slider 15 and the fixed groove 10, the contact plate 13 is in contact with the outer side of the fault identification device 6, the battery 11 is fixedly installed on the outer side of the fixing part a1 to supply power to the electrical equipment on the device, the holding rod 7 is fixedly connected to the side of the mounting bracket 5 away from the fixing part a1 to facilitate the staff to hold the device, and the outer periphery of the upper cleaning roller 3 and the lower cleaning roller 4 are provided with arc surfaces for use with cables.

[0030] The early warning device of this utility model includes a mounting frame 5. An audible and visual alarm 17 is fixedly installed on one side of the mounting frame 5. A controller 19 is fixedly installed on the outer side of the mounting frame 5 and at the end away from the audible and visual alarm 17. When the fault identification device 6 detects that the cable is torn, it will transmit the information to the controller 19, and the controller 19 will control the audible and visual alarm 17 to trigger an audible and visual alarm, thereby achieving the purpose of timely early warning.

[0031] Working principle: First, the operator places the equipment cable between fixing parts a1 and b2, and aligns it with the upper cleaning roller 3 and lower cleaning roller 4. Then, the operator uses the semi-threaded post 8 and locking nut 9 to fix one end of fixing parts b2 and a1, ensuring the cable is stable during testing. Next, the operator holds the handle 7 and moves it along the cable surface. As fixing parts a1 and b2 move together, the upper cleaning roller 3 and lower cleaning roller 4 clean the dust adhering to the cable's outer wall, ensuring the accuracy of the fault identification device 6. Simultaneously, the spring 16 pushes the upper cleaning roller... The upper cleaning roller 3 and the lower cleaning roller 4 converge towards the center so that the upper cleaning roller 3 and the lower cleaning roller 4 can always adhere to the surface of the cable to improve the cleaning effect of dust. In this way, the fault identification device 6 can complete the early fault identification process of the cable. When the fault identification device 6 detects that the cable is torn, it will transmit the information to the controller 19, and the controller 19 will control the audible and visual alarm 17 to trigger an audible and visual alarm, thereby achieving the purpose of timely warning. The fault identification device 6 in this device is the same as the fault identification device for communication equipment in Chinese Patent Publication No. CN211878033U, which belongs to the prior art and does not need to be described in detail.
