Description

Technical Field

[0001] This invention relates to the field of general cleaning technology, and in particular to an oil stain cleaning device and method for processing anti-settlement manhole covers. Background Technology

[0002] Anti-settlement manhole covers are a specially designed system to solve problems such as sinking and tilting caused by uneven foundation settlement of traditional manhole covers. This structure ensures the stability and safety of the manhole cover, reducing road unevenness and traffic safety hazards caused by manhole cover issues. During the manufacturing process of anti-settlement manhole covers, oil stains need to be cleaned.

[0003] Existing technology (CN212652232U) discloses an oil stain cleaning device for cast iron manhole cover processing. A sliding block moves, and a gripper grasps the edge of the manhole cover, allowing the cover to move between a cleaning tank and a placement platform for cleaning. Under the action of a second motor, a second drive pulley drives a belt roller to rotate, which is then transmitted via gears and a belt. Each brush roller rotates, and the manhole cover passes between two rows of brush rollers, thus completing the cleaning of both sides of the cover and improving cleaning efficiency. Under the action of a water pump, detergent from inside the cleaning tank enters the interior of the brush rollers through water pipes and is sprayed out through perforations on the brush rollers, thereby improving cleaning quality. Water from the brush rollers falls back into the cleaning tank, allowing for recycling and improving detergent utilization, thus reducing cleaning costs.

[0004] Using the above method, two rows of brush rollers are used to clean the manhole cover. However, the back of the manhole cover has many reinforcing ribs, which will create many dead corners that cannot be cleaned by the brush rollers, resulting in incomplete cleaning.

The manhole cover is moved to the left by the displacement component 106, and the clamping component 109 places the manhole cover onto the multiple support frames 102. At this time, the top diversion box 107 moves to the left side of the top frame 105. Then, the displacement component 106 moves the clamping component 109 to the right to reset, and simultaneously, the displacement component 106 moves the top diversion box 107 above the manhole cover. Multiple top nozzles 108 spray cleaning fluid downwards to rinse the front of the manhole cover, and multiple bottom nozzles 104 spray cleaning fluid upwards to rinse the back of the manhole cover.

The sliding seat 110 can slide left and right on the top frame 105. The connecting block 112 connects the output end of the first hydraulic cylinder 111 to the sliding seat 110, and the first hydraulic cylinder 111 drives the sliding seat 110 to slide left and right. The multiple lifting rods 113 are used to lift the top diversion box 107, so that the top diversion box 107 is at a suitable height.

[0033] Secondly, the second hydraulic cylinder 114 is fixedly connected to the sliding seat 110 and located at the bottom of the sliding seat 110; the disc 115 is fixedly connected to the output end of the second hydraulic cylinder 114 and located at the bottom of the second hydraulic cylinder 114; the two telescopic guide rods 116 are respectively fixedly connected to the sliding seat 110 and respectively fixedly connected to the disc 115, and respectively located at the top of the disc 115; the plurality of third hydraulic cylinders 117 are respectively fixedly connected to the disc 115 and respectively located at the top of the disc 115; the plurality of clamping blocks 118 are respectively slidably connected to the disc 115 and respectively fixedly connected to the output ends of the plurality of third hydraulic cylinders 117, and respectively located on the side of the disc 115. The second hydraulic cylinder 114 is used to drive the disc 115 to rise and fall, and the multiple third hydraulic cylinders 117 are used to drive the multiple clamping blocks 118 to move. The two telescopic guide rods 116 are used to guide the rise and fall of the disc 115. When clamping the manhole cover, the multiple third hydraulic cylinders 117 drive the multiple clamping blocks 118 to move away from each other, and then the manhole cover is placed between the multiple clamping blocks 118. Then the multiple third hydraulic cylinders 117 drive the multiple clamping blocks 118 to retract, so that the manhole cover can be clamped from four directions. The second hydraulic cylinder 114 can drive the four clamping blocks 118 to rise and fall, thereby driving the clamped manhole cover to rise and fall.

[0034] Meanwhile, the mounting cylinder 119 is fixedly connected to the sliding seat 110 and located at the bottom of the sliding seat 110; the slide rod 120 is slidably connected to the mounting cylinder 119 and fixedly connected to the disc 115, and located inside the mounting cylinder 119. The mounting cylinder 119 is used to slidably mount the slide rod 120, and when the disc 115 is raised or lowered, the slide rod 120 slides synchronously within the mounting cylinder 119.

When the manhole cover is placed on the multiple support frames 102, it is initially supported by the U-shaped rod 125. The U-shaped rod 125 will block the manhole cover, and the contact area cannot be washed. After washing for a period of time, the fifth hydraulic cylinder 124 drives one end of the L-shaped rod 126 to extend out from the support pile 121 to support the manhole cover. Then, the fourth hydraulic cylinder 123 drives the U-shaped rod 125 to retract and no longer support the manhole cover. At this time, only the L-shaped rod 126 supports the manhole cover, so that the parts of the manhole cover that were originally blocked by the U-shaped rod 125 can be washed, avoiding cleaning dead corners.

[0036] This embodiment describes an oil stain cleaning device for processing anti-settlement manhole covers. Multiple support frames 102 support the manhole cover. A bottom diversion box 103 is connected to a cleaning fluid via a hose, allowing the cleaning fluid to spray upwards from multiple bottom nozzles 104. A top diversion box 107 is connected to a cleaning fluid via a hose, allowing the cleaning fluid to spray downwards from multiple top nozzles 108. A top frame 105 mounts a displacement assembly 106. The top diversion box 107 and the clamping assembly 109 are positioned on the displacement assembly 106, one on the left and one on the right. The displacement assembly 106 drives the top diversion box 107 and the clamping assembly 109 to move synchronously left and right. The clamping assembly 109 is used to pick up and put down the manhole cover. In use... The clamping assembly 109 clamps the manhole cover, and then the displacement assembly 106 moves the manhole cover to the left. The clamping assembly 109 places the manhole cover onto the multiple support frames 102. At this time, the top diversion box 107 moves to the left side of the top frame 105. Then, the displacement assembly 106 moves the clamping assembly 109 to the right to reset. At the same time, the displacement assembly 106 moves the top diversion box 107 above the manhole cover. Multiple top nozzles 108 spray cleaning fluid downwards to rinse the front of the manhole cover, and multiple bottom nozzles 104 spray cleaning fluid upwards to rinse the back of the manhole cover. After cleaning, the displacement assembly 106 moves the clamping assembly 109 to the left to remove the cleaned manhole cover from the multiple support frames 102. By using the above method, high-pressure cleaning fluid is sprayed from multiple bottom nozzles 104 and multiple top nozzles 108 to rinse the front and back of the manhole cover, thus avoiding cleaning dead corners and solving the problem that existing oil stain cleaning devices for manhole cover processing cannot clean the manhole cover properly.

When the manhole cover is placed on the four horizontal rods 203, its sides are limited by the four vertical rods 202, thus achieving the positioning of the manhole cover. At this time, it is aligned with the clamping assembly 109, which facilitates the clamping assembly 109 to move down and clamp the manhole cover.

[0042] The oil stain cleaning device for processing anti-settlement manhole covers described in this embodiment places the manhole cover on the four horizontal bars 203, and the sides are limited by the four vertical bars 202 to achieve the positioning of the manhole cover.
