Description

Technical Field

[0001] The present invention relates to the technical field of safety interlocking of loading and unloading vehicles, and in particular to an intelligent safety interlocking device for loading and unloading vehicles. Background Art

[0002] The quantitative loading control system for vehicles carrying flammable liquids, liquefied hydrocarbons, and liquefied toxic gases requires the following activation conditions: complete human static discharge, intact vehicle static grounding, complete tank overflow connection, flammable and toxic gas leak detection and commissioning, intact oil and gas phase crane connections, and vehicle keys in place (make sure the vehicle is turned off). If any of these interlock conditions are not met, the quantitative loading system cannot be activated or will be immediately stopped.

[0003] Existing technology primarily ensures vehicle ignition is shut down by placing the vehicle key in a designated key box. Once the key is in place, a signal is given to the metered loading system to allow activation, allowing it to start. However, this method has certain drawbacks: 1. The key placed in the key box cannot be guaranteed to be the vehicle's key; 2. If the driver carries two keys, only one will be placed; 3. Keys vary in shape, and not all keys can fit in one key box, necessitating the use of multiple key boxes. Due to these drawbacks, existing technology cannot effectively prevent vehicles carrying flammable liquids, liquefied hydrocarbons, and liquefied toxic gases from starting during loading and unloading, making safety accidents highly likely. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The top of the vehicle body is fixed with a button bar, and the bottom of the button bar is fixed with a button bar, and the bottom of the button bar is fixed with a button bar.

[0006] As a preferred solution, the upper contact plate of the closer and the lower contact plate of the closer are both conductive metal sheets.

[0007] As a preferred solution, the closer is in an arc shape that bends outwards.

[0008] Compared with the prior art, the beneficial effect of the present invention is that the present invention can effectively prevent the vehicle from being started when the quantitative loading control system is loading and burning liquids, liquefied hydrocarbons and liquefied toxic gases by preventing the starting key of the hazardous chemical transport vehicle from being inserted into the keyhole when the quantitative loading system is working, thereby avoiding safety accidents such as explosions and gas leaks caused by vehicle starting when the quantitative loading control system is working. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0010] Figure 1 It is a schematic diagram of the connection structure of the present invention. DETAILED DESCRIPTION

[0011] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0012] An intelligent loading and unloading vehicle safety interlocking device comprises a base 1, a connecting card plate 2 is provided on the top of the base 1, the top surface of the connecting card plate 2 is an inclined surface, an anti-starting cap 3 is connected to the base 1 through the connecting card plate 2, a buckle 4 is provided at the bottom of the anti-starting cap 3, the buckle 4 of the anti-starting cap 3 is clamped on the connecting card plate 2; the anti-starting cap 3 comprises an anti-starting cap barrel 301 and an anti-starting cap cover 302, a power supply 5, a signal transmitter 6, and a positioning chip 7 are provided in the anti-starting cap barrel 301, one end of the anti-starting cap cover 302 is hinged to the anti-starting cap barrel 301, and a closer upper touch plate 8 is provided at the other end where it is buckled with the anti-starting cap barrel 301, a closer lower touch plate 9 is provided in the anti-starting cap barrel 301 at a position corresponding to the closer upper touch plate 8, and the closer The lower touch plate 9 of the device is fixed on a vertically arranged support plate 10, and the support plate 10 is connected to an inclined protective inclined plate 12 through a spring 11. A linkage rod 13 is also provided between the protective inclined plate 12 and the support plate 10, and the spring 11 is placed below the linkage rod 13. A socket 14 is formed between the protective inclined plate 12 and the top of the support plate 10, and a closer 15 is provided at the bottom of the protective inclined plate 12; when the anti-start cap 3 is separated from the base 1, the spring 11 pops open and at the same time bounces the lower part of the protective inclined plate 12 inward and the upper part of the protective inclined plate 12 outward, and the protective inclined plate 12 covers the lower touch plate 9 of the closer to prevent the anti-start cap 3 from being connected to the base 1, and the anti-start cap tube 301 and the anti-start cap cover 302 from being engaged, causing the circuit to close and send an error signal.

[0013] Furthermore, the upper contact plate 8 of the closer and the lower contact plate 9 of the closer are both conductive metal sheets.

[0014] Furthermore, the closer 15 is in the shape of an arc that bends outward. When an arc-shaped closer 15 is provided that bends outward, when the anti-start cap 3 is connected to the base 1, it can ensure that the inclined surface of the card plate 2 pushes the closer 15 to move outward, thereby pushing the lower part of the protective inclined plate 12 to move outward, preventing the protective inclined plate 12 from being pushed to the outside of the card plate 2. At the same time, the upper part of the protective inclined plate 12 moves inward, and the protective inclined plate 12 leaves the lower touch plate 9 of the closer and forms a socket 14 with the top of the support plate 10, which facilitates the buckling of the anti-start cap 302.

[0015] Base 1 is designed based on the shape of the vehicle's keyhole and permanently fixed around it, ensuring it is roughly flush with the keyhole's base surface. It can be slightly lower or higher, but this should not prevent the key from fully inserting into the keyhole and turning to start the vehicle. To activate the vehicle's quantitative loading system, remove the vehicle key and connect base 1 to anti-start cap 3 via snap 4. The anti-start cap 302 of the anti-start cap 3 is fastened with an upper touch plate 8 of the closer, and a lower touch plate 9 of the closer is provided at a position corresponding to the upper touch plate 8 of the closer in the anti-start cap tube 301. After the anti-start cap 3 is closed, the upper touch plate 8 of the closer and the lower touch plate 9 of the closer are in contact with each other, so that the circuit of the entire system is closed and energized, thereby achieving the closure of the circuit of the entire system. At this time, the signal transmitter 6 is started, and the signal transmitter 6 controls the positioning chip 7 to start detecting the displacement of the anti-start cap 3 within 3 seconds. When the maximum displacement does not exceed 5 mm, it is determined that the anti-start cap 3 as a whole has not been moved. After 2 seconds, the signal transmitter 6 will send a loading signal to the quantitative loading system, allowing the quantitative loading system to start loading. During the loading process, when the displacement of the anti-start cap 3 exceeds 5 mm, that is, the anti-start cap 3 is removed, the car key can be inserted into the keyhole to start the vehicle. For a car whose quantitative loading control system is loading liquids, liquefied hydrocarbons and liquefied toxic gases, once the vehicle is started, it will cause safety accidents such as explosion and leakage, which poses a great safety hazard. When the positioning chip 7 detects that the displacement of the anti-start cap 3 exceeds 5 mm, the signal transmitter 6 controls the alarm system to alarm and send a stop loading signal to the quantitative loading system to stop loading.

[0016] The above is a detailed description of the specific implementation of the present invention, but it is only an example. The present invention is not limited to the specific implementation cases described above, and equivalent modifications to the present invention are also within the scope of protection of the present invention.
