Description

Technical Field

[0001] This utility model relates to the field of mop head adjustment technology, specifically a mop head height automatic adjustment device. Background Technology

[0002] During operation, the condition of the trailing strip on a tanker refueling truck is closely related to the vehicle's load and safety. When the tanker refueling truck is fully loaded, the length of the trailing strip can be adjusted to a suitable position to ensure proper contact with the ground and perform safety functions such as static electricity discharge. However, as refueling operations continue and the amount of fuel in the tank gradually decreases, the vehicle height increases accordingly. At this point, the trailing strip may leave the ground, failing to achieve grounding. This situation prevents the timely discharge of static electricity generated during operation, which can easily accumulate and create safety hazards, potentially leading to dangerous accidents such as fires or even explosions.

[0003] On the other hand, if the tow strap is adjusted to a suitable position when the tanker truck is empty, the contact area of ​​the tow strap will increase excessively when the vehicle is full of fuel and the vehicle body lowers. This excessively increased contact area will cause the tow strap to experience excessive friction during vehicle movement, leading to excessive wear. When the vehicle body is raised, the tow strap will not be effectively grounded, and static electricity generated during the operation of the refueling truck cannot be discharged in time. Excessive wear of the tow strap not only shortens its service life, increases replacement costs and maintenance frequency, but more importantly, the worn tow strap cannot effectively perform its safety function, posing a serious threat to the safe operation of the refueling truck.

[0004] To effectively address the issue of the drag strip failing to function properly due to changes in load on tanker refueling trucks, designing a targeted device is particularly necessary. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a solution for an automatic adjustment device for the height of the drag strip.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic adjustment device for the height of a drag strip, comprising a drag strip adjustment component, a pull cable, and a relative motion component; The tow belt adjustment assembly includes a device fixing bracket, and a tow belt reel bracket is slidably connected to the outer surface of the device fixing bracket. The device fixing bracket is fixed to the surface of the vehicle body. The relative motion component includes a cable axle fixing bracket and a cable body fixing bracket. The cable axle fixing bracket is fixed to the surface of the axle, and the cable body fixing bracket is fixed to the surface of the vehicle body. An outer sleeve is fixed to the outer surface of the cable axle fixing bracket. The cable is used to transmit signals of changes in vehicle height. One end of the cable is fixed to the drag belt reel bracket, and the other end slides through the outer casing and is fixed to the cable body fixing bracket.

[0007] As a further description of the above technical solution: The cable bridge fixing bracket and the cable body fixing bracket slide relative to each other.

[0008] As a further description of the above technical solution: A return spring is provided between the drag belt reel bracket and the device fixing bracket.

[0009] As a further description of the above technical solution: The drag strip reel bracket has a drag strip reel installed inside, and the drag strip reel is rotatably connected to the drag strip reel bracket. A conductive slip ring is installed at one end of the drag strip reel.

[0010] As a further description of the above technical solution: The bottom end of the mop belt reel bracket is equipped with a mop belt sagging end fixer for fixing the sagging mop belt.

[0011] This utility model has the following beneficial effects: This invention, through the clever design and installation of a trailing strip adjustment component, a pull cable, and a relative motion component, can automatically adjust the length of the trailing strip in real time according to changes in the load of the tanker truck. This ensures that the trailing strip maintains proper contact with the ground regardless of whether the vehicle is fully loaded, empty, or experiencing load changes. This avoids the potential for static electricity buildup caused by the trailing strip being off the ground, ensuring the safe operation of the refueling truck; it also prevents excessive wear on the trailing strip, extending its service life and reducing maintenance costs.

Detailed Implementation

[0014] 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.

[0015] Reference Figures 1-4 One embodiment provided by this utility model: An automatic tow belt height adjustment device includes a tow belt adjustment component 1, a pull cable 2, and a relative motion component 3. The tow belt adjustment component 1 includes a device fixing bracket 11, and a tow belt reel bracket 12 is slidably connected to the outer surface of the device fixing bracket 11. The device fixing bracket 11 is fixed to the surface of the vehicle body 4. The relative motion component 3 includes a pull cable axle fixing bracket 31 and a pull cable vehicle body fixing bracket 32. The pull cable axle fixing bracket 31 is fixed to the surface of the axle 5, and the pull cable vehicle body fixing bracket 32 ​​is fixed to the surface of the vehicle body 4. An outer sleeve 33 is fixed to the outer surface of the pull cable axle fixing bracket 31. The pull cable 2 is used to transmit a vehicle height change signal. One end of the pull cable 2 is fixed to the tow belt reel bracket 12, and the other end slides through the outer sleeve 33 and is fixed to the pull cable vehicle body fixing bracket 32.

[0016] The cable puller axle fixing bracket 31 and the cable puller body fixing bracket 32 ​​slide relative to each other. That is, when the cable puller body fixing bracket 32 ​​is full of oil, the cable puller body fixing bracket 32 ​​will move downward with the vehicle body, while the position of the cable puller axle fixing bracket 31 remains basically unchanged. Only by sliding relative to each other can the cable 2 be adjusted.

[0017] A return spring 13 is provided between the drag strip reel bracket 12 and the device fixing bracket 11. The return spring 13 is used to maintain the position of the drag strip reel bracket 12, and causes the drag strip reel bracket 12 to return to its original position after the motion signal disappears. A drag strip reel 14 is installed inside the drag strip reel bracket 12. The drag strip reel 14 is rotatably connected to the drag strip reel bracket 12, which can realize the winding of the drag strip. A conductive slip ring 15 is installed at one end of the drag strip reel 14 for reliable connection between the rotating drag strip and the vehicle body 4. A drag strip drooping end fixer 16 is installed at the bottom end of the drag strip reel bracket 12 for fixing the drooping drag strip. The drag strip drooping end fixer 16 specifically includes an N-shaped frame that fixes the bottom end of the drag strip reel bracket 12. An adjusting rod is threadedly connected to the surface of the N-shaped frame. One end of the adjusting rod is connected to a pressure plate. The position of the pressure plate can be adjusted by rotating the adjusting rod, and the position of the drag strip is fixed by the pressure plate.

[0018] Working Principle: When the fuel tanker is heavily loaded, the weight of the fuel truck is significant. The suspension (e.g., leaf springs are bent, airbags are compressed, hydraulic cylinder piston rods are pressed in) is compressed. This causes the vehicle body 4 to move downwards relative to the axle 5, reducing the vehicle height and decreasing the distance between the axle 5 and the vehicle body 4 frame. When unloaded / lightly loaded, the fuel tank is emptied or nearly emptied, significantly reducing the weight. The elastic elements of the suspension (leaf springs rebound, airbags inflate, hydraulic cylinder piston rods extend under the action of internal gas or springs) extend / rebound. This causes the vehicle body 4 to move upwards relative to the axle 5, increasing the vehicle height and increasing the distance between the axle 5 and the vehicle body 4 frame. Therefore, innovations are made based on the basic structure of the fuel truck described above.

[0019] When the refueling truck is full of oil, the vehicle body 4 moves downward relative to the axle 5. Therefore, the cable body fixing bracket 32 ​​connected to the vehicle body 4 will move downward relative to the cable axle fixing bracket 31 connected to the axle 5. When the cable body fixing bracket 32 ​​moves downward, it will drive the cable 2 to move downward, thereby driving the drag strip reel bracket 12 connected to the other end to rise, so that the drag strip on the surface of the drag strip reel 14 rises. This allows the drag strip to rise relatively when the refueling truck body 4 moves downward after being full of oil, thus shortening its length and maintaining appropriate contact with the ground without being too long.

[0020] Similarly, when the refueling truck is refueling, the amount of oil in the tank will gradually decrease, so the vehicle body 4 will rise relative to the axle 5. As a result, the cable 2 will also rise, causing the trailing belt reel bracket 12 at one end to fall, so that the trailing belt continues to maintain proper contact with the ground.

[0021] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
