Description

Technical Field

[0001] This utility model relates to the field of grounding resistance detection, and in particular to a grounding resistance detection alarm device based on a quantitative loading tank truck. Background Technology

[0002] In quantitative loading operations in industries such as chemicals and petroleum, the reliability of tank truck electrostatic grounding is directly related to production safety in flammable and explosive environments. As a core device ensuring effective static electricity discharge, the grounding resistance detection and alarm device for quantitative loading tank trucks is crucial for safe production processes due to its stability, maintainability, and efficient wire management. This device monitors the grounding resistance value in real time and can promptly alarm in case of grounding failure, preventing major safety accidents such as explosions and fires caused by static electricity accumulation. Therefore, it is widely used in the storage and transportation of hazardous chemicals.

[0003] Existing ground resistance detection and alarm devices for quantitative loading tank trucks suffer from significant technical bottlenecks in practical applications. On one hand, the connection structure between the detection alarm body and the support frame and mounting base often employs complex combinations of bolt fixing or snap-fit ​​mechanisms. Maintenance requires disassembly layer by layer using tools such as screwdrivers and wrenches, making the process cumbersome and time-consuming. On the other hand, the device lacks a systematic mechanical structure for wire storage; the wires are typically directly wound around the bracket or randomly fixed. When adjusting the detection position or retracting the wires, they are prone to knotting and tangling due to external force. To address these technical problems, this application proposes a ground resistance detection and alarm device for quantitative loading tank trucks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grounding resistance detection alarm device for quantitative loading tank trucks. The detection alarm body can be quickly disassembled through simple tossing and rotation operations, improving maintenance efficiency and reducing maintenance costs. The device utilizes a spring reset and locking structure to achieve orderly winding of the wires, avoiding tangling, ensuring safe operation of the equipment, extending the life of the wires, and improving the cleanliness of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The device for detecting and alarming the grounding resistance of a quantitatively loaded tank truck includes a support frame. A mounting base is fixedly connected to the front of the support frame. A mounting block is connected to the front of the mounting base via a plug-in assembly. A detection alarm body is fixedly connected to the front of the mounting block. A limit ring is rotatably connected to the top of the mounting base. A limit assembly is provided at one end of the limit ring for mounting the detection alarm body. Winding rollers are rotatably connected to both sides of the support frame. A fixing block is fixedly connected to the outer wall of the support frame. A sliding rod is slidably connected to the outer wall of the fixing block. The top end of the sliding rod is connected to the outer wall of the winding roller via a locking assembly for fixing the winding roller. A wire is provided on the bottom side of the detection alarm body.

[0007] Furthermore, the plug-in assembly includes a plug-in slot formed on the rear side of the mounting block, and a plug-in shaft is fixedly connected to the front side of the mounting base, the plug-in shaft being disposed inside the plug-in slot.

[0008] Furthermore, the limiting component includes a plug shaft slidably connected to the rear side of the limiting ring, a spring is provided on the inner wall of one end of the limiting ring, a plug hole is provided on the outer wall of the support frame, and the plug shaft is disposed inside the plug hole.

[0009] Furthermore, the engaging assembly includes an arc-shaped block fixedly connected to the top of the slide rod, and protrusions are fixedly connected to both the outer wall of the winding roller and the inner wall of the arc-shaped block. A spring is provided on the outer wall of the slide rod.

[0010] Furthermore, one end of the spring is connected to the bottom side of the arc-shaped block, and the other end of the spring is connected to the top side of the fixed block.

[0011] Furthermore, the conductor is disposed on the outer wall of the winding roller.

[0012] Furthermore, the bottom side of the support frame is provided with a mounting column for fixing the support frame.

[0013] Furthermore, a lever is fixedly connected to the outer wall of the insertion shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a grounding resistance detection and alarm device for quantitative loading tank trucks, comprising a support frame 1, a mounting base 2 fixedly connected to the front side of the support frame 1, a insertion slot formed on the rear side of the mounting block 12, a insertion shaft 13 fixedly connected to the front side of the mounting base 2, the insertion shaft 13 being disposed inside the insertion slot, a detection and alarm body 3 fixedly connected to the front side of the mounting block 12, a limit ring 11 rotatably connected to the top side of the mounting base 2, and a insertion shaft 14 slidably connected to the rear side of the limit ring 11, with a spring provided on the inner wall of one end of the limit ring 11. 15. The outer wall of the support frame 1 is provided with an insertion hole, and the insertion shaft 14 is set inside the insertion hole for installation of the detection alarm body 3. Both sides of the support frame 1 are rotatably connected with a winding roller 5. The outer wall of the support frame 1 is fixedly connected with a fixing block 8. The outer wall of the fixing block 8 is slidably connected with a slide rod 6. An arc-shaped block 9 is fixedly connected to the top of the slide rod 6. The outer wall of the winding roller 5 and the inner wall of the arc-shaped block 9 are both fixedly connected with protrusions 10. The outer wall of the slide rod 6 is provided with a spring 7 for fixing the winding roller 5. The bottom side of the detection alarm body 3 is provided with a wire 4.

[0025] Specifically, when maintenance is required on the support frame 1, the lever 16 can be moved first. The lever 16 will cause the insert shaft 14 to slide, thereby compressing the second spring 15. As the second spring 15 is compressed, the insert shaft 14 will gradually disengage from the insertion hole on the outer wall of the support frame 1. At this time, the limiting ring 11 is rotated to separate it from the outer wall of the mounting base 2. Next, the detection alarm body 3 and the mounting block 12 are pulled out from the front side of the mounting base 2, and the slot on the outer wall of the mounting block 12 is pulled out from the outer wall of the insert shaft 13, thereby completing the disassembly of the detection alarm body 3 for maintenance. If the detection alarm body 3 is no longer working, the wire 4 at its bottom can be removed by first pulling the slide bar 6, causing the slide bar 6 to move the arc block 9 along the fixed block 8, thereby compressing the first spring 7. At this time, the arc block 9 will disengage from the outer wall of the winding roller 5. Then, the wire 4 is wound around the outer wall of the winding roller 5. After winding is complete, release the slide bar 6, and the spring 7 will return to its original position, causing the arc-shaped block 9 to press against the outer wall of the winding roller 5 again. Finally, through the engagement between the protrusions 10, the wire 4 is wound in an orderly manner, preventing the wire 4 from becoming tangled and ensuring its normal use.

[0026] Reference Figures 2-4 One end of spring 7 is connected to the bottom side of arc block 9, and the other end of spring 7 is connected to the top side of fixed block 8. Wire 4 is set on the outer wall of winding roller 5. A mounting post is set on the bottom side of support frame 1 for fixing support frame 1. Paddle 16 is fixedly connected to the outer wall of insert shaft 14.

[0027] Specifically, the compression and reset of spring 7 control whether the arc block 9 limits the winding roller 5. The winding roller 5 can wrap the wire 4 to prevent it from falling off.

[0028] Working principle: When the support frame 1 needs maintenance, the insert shaft 14 can be slid by moving the lever 16 to compress the spring 15, causing the insert shaft 14 to disengage from the insertion hole on the outer wall of the support frame 1. Then, the limiting ring 11 is rotated to disengage from the outer wall of the mounting base 2. The detection alarm body 3 and the mounting block 12 are then pulled out from the front of the mounting base 2, and the slot on the outer wall of the mounting block 12 is pulled out from the outer wall of the insert shaft 13, thus disassembling the detection alarm body 3 for easy maintenance. When the detection alarm body 3 is no longer working, the wire 4 at its bottom can be separated from the outer wall of the winding roller 5 by pulling the slide rod 6 to compress the spring 7. The wire 4 is then wound around the outer wall of the winding roller 5. By releasing the slide rod 6 and restoring the spring 7, the arc block 9 is pressed against the outer wall of the winding roller 5. The engagement between the protrusions 10 ensures that the wire 4 is wound in an orderly manner, preventing the wire 4 from becoming tangled and affecting its use.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
