[0034] The height-adjustable steel belt cleaning trolley is designed to provide convenient, safe, reliable, and height-adjustable steel belt cleaning services for various working environments. It can adapt to cleaning needs at different heights and angles, improve cleaning efficiency, and is easy to operate and highly mobile.

[0035] The main body 1 of the steel belt cleaning cart simply relies on the motor 39 to drive the water spray brush 40 to rotate and clean the surface of the steel belt. The bottom of the basin of the main body 1 of the steel belt cleaning cart is flat and fits into the upper guide rail 5. In order to better fit into the upper guide rail 5 and not affect the use effect, the original sloping bottom of the lower water basin of the main body 1 of the steel belt cleaning cart has been changed to a flat bottom.

[0036] The support device includes: a front base 6, a rear base 7, a push rod 8, a brake-type directional heavy-duty caster 2, a brake-type omnidirectional heavy-duty caster 3, and a square tube support 10. The brake-type directional heavy-duty caster 2 is installed at the bottom of the front base 6, the brake-type omnidirectional heavy-duty caster 3 is installed at the bottom of the rear base 7, and the push rod 8 is fastened to the rear base 7.

[0037] The lower guide rail 4 includes two horizontally arranged rails facing each other, with the rails positioned inside the guide rails. The front and rear ends of the lower guide rail 4 are respectively fastened to the front base 6 and the rear base 7. The two ends of the square tube support 10 are respectively fastened to the two guide rails.

The front directional and rear swivel distribution will better propel the trolley, saving effort and time. Once it reaches the designated position, engage the brakes on the four heavy-duty casters to secure the trolley in place. The entire liftable steel belt cleaning trolley is constructed of steel, providing high stability and heavy-duty capacity. The braked heavy-duty casters, combined with the trolley's structural weight, ensure that the trolley remains firmly in place. The entire support system provides a sturdy base for the trolley, enabling it to work smoothly, efficiently, and safely.

[0039] The lifting device includes two sets of X-shaped connecting brackets 11 with inner and outer overlapping. The overlapping part of the two sets of connecting brackets 11 is fastened to the connecting column 14.

The upper rail 5 and lower rail 4 fixed on the upper and lower sides enclose the rollers 13, allowing the rollers 13 to move horizontally in a linear motion within their range.

[0042] There are two sets of overlapping connecting brackets 11. Both sets are connected to connecting columns 14 and large connecting columns 15 near the middle and both ends, forming two sets of stable, compact, high-lifting, parallel scissor-like structures. When the connecting column 14 or large connecting column 15 is pushed forcefully, the rollers 13 connected to the connecting bracket 11 can move within the upper rail 5 and lower rail 4, thereby changing the amplitude of the connecting bracket 11, changing the height between the lower guide rail 4 and the upper guide rail 5, and causing the steel belt cleaning trolley body 1, which is fixed to the upper guide rail 5 and the upper U-shaped fixed seat 12, to move vertically, thus realizing the lifting and lowering adjustment of the steel belt cleaning trolley. The compact and stable lifting device plays a role in force transmission and guidance.

[0043] The tilting device includes: a front pad 28, a rear pad 29, and a cylinder 32. The front pad 28 and the rear pad 29 are respectively fastened to the front and rear sides of the upper surface of the upper guide rail 5. The bottom front side of the steel strip cleaning trolley body 1 is hinged to the front pad 28 through the front hinge assembly 38.

[0044] The tilting device also includes: support rods 35 and support columns 36. One end of the two support rods 35 is connected to the outside of the two guide rails of the upper guide rail 5 through fixing buckles 34. The two support columns 36 are respectively set on the outer surfaces of the two sides of the main body 1 of the steel belt cleaning trolley. The other end of the support rods 35 is provided with a fork-shaped structure that matches the support columns 36. The outside of the two guide rails of the upper guide rail 5 is also provided with anti-slip buckles 37 that match the front end of the support rods 35.

[0045] The main components of the tilting device are the front end pad 28, the rear end pad 29, the rear end hinge assembly 30, the rear end support column 31, the cylinder 32, the upper end hinge assembly 33, the fixing buckle 34, the support rod 35, the support column 36, the anti-slip buckle 37, and the front end hinge assembly 38. The front end pad 28 and the rear end pad 29 are both fixed to the upper surface of the upper track 5, with their end faces flush. The upper part of the front end hinge assembly 38 is fixed to the front bottom surface of the steel strip cleaning trolley body 1; the lower part is fixed to the front end pad 28. The rear end hinge assembly 30 is fixed to the rear end pad 29 through the hole at the tail end of the cylinder 32. The upper end hinge assembly 33 is fixed to the middle and rear end bottom surface of the steel strip cleaning trolley body 1 through the front end of the telescopic rod of the cylinder 32. The rear end support column 31 is fixed to the rear end pad 29, supporting the steel strip cleaning trolley body 1 in a horizontal position.

[0046] The fixing buckle 34 passes through the hole at the end of the support rod 35 and is fixed to the sides of the upper rail 5 on both sides. The support column 36 is fixed to both sides of the main body 1 of the steel strip cleaning trolley. The anti-slip buckle 37 is fixed to the sides of the upper rail 5 on both sides. Normally, the front end of the support rod 35 rests on the anti-slip buckle 37 and is not used. When the steel strip cleaning trolley finishes its steel strip cleaning operation, and it is necessary to drain water, clean and maintain the main body of the steel strip cleaning trolley, or in other special steel strip cleaning environments where the steel strip cleaning trolley needs to be lifted and tilted to a certain angle, the extension and retraction of the drive mechanism cylinder 32 drives the main body 1 of the steel strip cleaning trolley to rotate within an acute angle range from the horizontal plane in the counterclockwise direction with the front hinge group 38 as the rotation center to achieve tilting. The front end of the support rod 35 is forked against the support column 36 to provide safe and reliable auxiliary support, greatly improving safety. This allows for rapid drainage of water inside the main body 1 of the steel strip cleaning trolley, while also facilitating necessary cleaning and maintenance of the cleaning trolley, ensuring that the equipment is in good condition for the next use, extending the service life of the equipment and maintaining its performance.

[0047] The transmission device includes: a foot pedal 9 and a hydraulic cylinder 17. The foot pedal 9 and the hydraulic cylinder 17 are connected in a transmission manner. The front end of the piston rod of the hydraulic cylinder 17 is connected to the large connecting column 15 through an ear-type support 16, and the rear end of the hydraulic cylinder 17 is connected to the square tube support 10 through a fixed seat 22.

[0048] The push rod 8 is equipped with a handle rod 23, which is connected to the cylinder lock valve 26 on the rear piston rod of the cylinder 17 via a lowering pull rope 24.

[0049] The main components of the transmission device are the foot pedal 9, the lug support 16, the hydraulic cylinder 17, the outer connecting plate 18, the compression spring 19, the inner connecting plate 20, the intermediate connecting plate 21, the fixed seat 22, the handle rod 23, the lowering rope 24, the guide block 25, the hydraulic cylinder locking valve 26, and the spring cover plate 27. The lug support 16 is welded to the middle of the large connecting column 15. The front end of the piston rod of the hydraulic cylinder 17 is connected to the lug support 16, and the rear end is connected to the fixed seat 22 via the outer connecting plate 18; the fixed seat 22 is welded to the middle of the square tube support 10; the piston rod at the rear end of the hydraulic cylinder 17 passes through the compression spring 19 and the spring cover plate 27 and connects to the inner connecting plate 20, the other end of which is connected to the intermediate connecting plate 21. The upper end of the intermediate connecting plate 21 is connected to the fixed seat 22, the middle position is connected to the inner connecting plate 20, and the lower end is connected to the foot pedal 9. This ensures that the position of the hydraulic cylinder 17 is relatively fixed, providing power for the lifting device.

[0050] A handle lever 23 is mounted on the push rod 8, and a lowering rope 24 is connected to the handle lever 23. The lowering rope 24 passes through the guide block 25 and is connected to the cylinder locking valve 26 on the piston rod at the rear end of the cylinder 17. When the foot pedal 9 is subjected to external force and moves downward, the foot pedal 9 drives the intermediate connecting piece 21, and the intermediate connecting piece 21 drives the inner connecting piece 20. Under this series of connections, the inner connecting piece 20 pushes the piston rod at the rear end of the cylinder 17 forward. After reaching the limit, it rebounds in the opposite direction under the action of the compression spring 19 and the spring cover plate 27. In this reciprocating motion, the piston rod at the front end of the cylinder 17 continuously extends and pushes the large connecting column 15, thereby driving the lifting device structure to continuously unfold. By stopping the foot pedal 9, the lifting device can be stopped at any position within the lifting range. When the cleaning operation is completed or the height needs to be adjusted downwards, pull the handle lever 23 so that the lowering rope 24 pulls the cylinder locking valve 26 within the appropriate position range through the guide block 25 to prevent it from being damaged. The cylinder locking valve 26 releases pressure, allowing the front piston rod of the cylinder 17 to return to its original position at a constant speed, which drives the unfolded lifting device structure to fold down at a constant speed, thus completing the lifting task.

[0051] Hydraulic cylinders rely on hydraulic pressure to drive loads to achieve linear motion. They are the simplest and most widely used hydraulic actuators. Hydraulic drives can achieve long-distance driving without the need to connect to external power sources. They are adaptable to various working environments and are convenient and reliable.

[0052] This application employs an overlapping connecting bracket 11, with one end connected to a U-shaped fixing seat 12 and the other end connected to a roller 13. The connecting column 14 and the large connecting column 15 form two sets of parallel cross structures. The extension and retraction of the hydraulic cylinder 17 telescopic rod drives the connecting bracket 11, thereby changing the height between the lower guide rail 4 and the upper guide rail 5, and realizing the lifting and lowering adjustment.

[0053] The front end of the steel strip cleaning trolley body 1 of this application is connected to the front end pad 28 fixed on the upper guide rail 5 via two sets of front end hinge groups 38. The tail end of the cylinder 32 is connected to the rear end hinge group 30 fixed on the rear end pad 29, and the front end of the cylinder 32 is connected to the upper end hinge group fixed on the bottom surface of the steel strip cleaning trolley body 1. The extension and retraction of the cylinder 32 of the drive mechanism drives the steel strip cleaning trolley body 1 to rotate around the front end hinge group 38 in an acute angle range from the horizontal plane in the counterclockwise direction, thus tilting it. The front end of the support rod 35 forks against the support column 36 to provide a safe and reliable auxiliary support structure. This facilitates rapid drainage of water inside the cleaning trolley body and also facilitates necessary cleaning and maintenance of the cleaning trolley, ensuring that the equipment is in good condition for the next use, extending the service life of the equipment and maintaining its performance.

[0054] This application achieves the function of fixing and supporting the main body 1 of the steel belt cleaning trolley by symmetrically installing U-shaped fixing seats 12 and upper guide rails 5 on both sides of the lower surface of the main body 1 of the steel belt cleaning trolley.

[0055] This application employs a structure that combines a lifting device and a transmission device, allowing the extension and retraction of the hydraulic cylinder 17 to drive the roller 13, which is connected in parallel to the connecting bracket 11, to move within the tracks of the upper rail 5 and the lower rail 4. This changes the height between the lower guide rail 4 and the upper guide rail 5, thereby achieving lifting and lowering. This makes the cleaning work more flexible and can provide effective steel belt cleaning services for equipment of different heights, making it widely applicable to various scenarios.

[0056] This application adopts a support structure based on brake-type directional heavy-duty casters 2 and brake-type swivel heavy-duty casters 3, with a front-directional and rear-swivel distribution, which will better push the trolley, making it convenient, fast, labor-saving and time-saving. Thus, the liftable steel belt cleaning trolley can be moved to the cleaning position or fixed in place to ensure stability, and has high mobility and heavy load capacity.
