Description

Technical Field

[0001] The utility model relates to the technical field of early warning for road rollers, in particular to an early warning device for edge rolling of road rollers. Background Art

[0002] A road roller, also known as a soil roller, is a piece of road construction equipment. Among engineering machinery, a road roller belongs to the category of road equipment and is widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. It can compact sandy, semi-sticky and sticky soils, roadbed stabilized soil and asphalt concrete pavement layers. The road roller uses the gravity of the machine itself and is suitable for various compaction operations, causing the compacted layer to produce permanent deformation and become dense. Road rollers are divided into two types: steel wheel type and tire type. The roller wheel structures include smooth roller, grooved roller and sheep's foot roller. Smooth roller is the most commonly used and is mainly used for compacting the surface layer of the road. It adopts mechanical or hydraulic transmission, can concentrate force to compact the protrusions, and has high compaction flatness, which is suitable for asphalt pavement compaction operations.

[0003] The patent document with publication number CN216688907U discloses an early warning device for a road roller for construction engineering, comprising a road roller body, an equipment box and a water tank respectively provided on the road roller body, a submersible pump provided on the top surface of the bottom plate of the water tank, a limiting mechanism with a limiting block and a cleaning mechanism with a cleaning brush respectively provided in the equipment box, and by arranging a fixing rod, a compression spring, a connecting plate and a limiting block, the camera can be fixed and limited, and the vibration generated by the operation of the road roller can be well buffered to extend its service life, and by arranging a nozzle and a cleaning brush, the lens of the camera can be cleaned by the nozzle when the road roller is working, and the cleaning brush can be used to further clean the lens by the operation of the second multi-stage electric push rod to ensure the clarity of the camera lens, and after the work is completed, the camera can be stored inside the equipment box to reduce dust pollution.

[0004] When the above application is in use, although the cleaning brush is used to further clean the lens through the second multi-stage electric push rod to ensure the clarity of the camera lens, and after the work is completed, the camera can be stored in the equipment box to reduce dust pollution, but when the roller is working, it is impossible to monitor and alarm the distance between the roller and the roadside and curb. It is necessary to frequently observe the display device at one end of the camera. If the roller wheel is at the edge of the road or close to the curb without observation, it will cause damage to the curb or cause the roller position to shift. Utility Model Content

[0033] An early warning assembly 11 is provided at the bottom of the horizontal plate 2. The early warning assembly 11 includes a shell 110 installed at the bottom of the positioning plate 1. A moving rod 111 is inserted at the bottom of the shell 110. A slide 112 is fixedly installed at one end of the moving rod 111 located inside the shell 110. Limit rods 113 are fixedly installed on both sides of the inner top wall of the shell 110. The bottom of the limit rod 113 passes through the slide 112 and extends to the outside of the slide 112 and is fixedly connected to the inner bottom wall of the shell 110. A return spring 114 is provided around the surface of the limit rod 113. Touch blocks 115 are fixedly installed on both sides of the bottom of the slide 112, touch switches 116 are fixedly installed on both sides of the bottom wall of the shell 110, and a distance sensor 118 is fixedly installed on one side of the shell 110. A mounting groove is provided at the bottom of the moving rod 111, and a roller 117 is connected to the inside of the mounting groove through a rotating shaft. The early warning component 11 is set to realize the early warning of the roller when rolling on the edge and protect the curbstone to avoid damage to the curbstone or displacement of the pressure wheel position. It is necessary to pay attention to the display device at all times to make the operation of the staff simpler and more convenient. The distance sensor 118, the touch switch 116 and the alarm 5 are all electrically connected to the controller on the roller. The distance sensor 118 is model HG-1100, and its detection range is 65-135mm. The top of the reset spring 114 is fixedly connected to the inner top wall of the shell 110, and the bottom of the reset spring 114 is fixedly connected to the bottom of the slide 112. The reset spring 114 is set to reset the touch block 115 on the slide 112. The slider 112 is provided with a limiting hole for the limiting rod 113 to pass through, and the inner wall of the limiting hole is slidably connected to the surface of the limiting rod 113. Sliding bars 8 are fixedly installed on both sides of the inner wall of the shell 110, and sliding grooves are provided on both sides of the slider 112 for the sliding bar 8 to pass through. The inner wall of the sliding groove is slidably connected to the surface of the sliding bar 8. The limiting holes are set to facilitate the sliding of the slider 112 on the limiting rod 113. At the same time, the setting of the sliding bar 8 realizes the limitation of the slider 112, keeping the slider 112 from shaking left and right while moving up and down.

[0034] Reference Figure 2 The upper surface of the hook 7 is provided with a groove, and the splint 10 and the anti-slip strip 13 are provided to achieve an anti-slip effect during fixed installation, which is convenient for the installation and positioning of the device.

[0035] Reference Figure 1 In a preferred embodiment, a bolt 14 is inserted into the upper surface of the horizontal plate 2, and the bottom of the bolt 14 passes through the horizontal plate 2 and extends to the inside of the limiting groove and is threadedly connected to the upper surface of the limiting plate 3. A screw hole for the bolt 14 to pass through is opened on the horizontal plate 2, and the screw hole is threadedly connected to the bolt 14, and the screw hole is connected to the limiting groove. The provided screw rod 9 and bolt 14 facilitate the installation of the entire device in actual application, and also facilitate the replacement and disassembly and storage of components on the device, thereby improving the convenience of use of the device.

[0036] Working principle: When in use, loosen the screw rod 9, and then make the screw rod 9 drive the splint 10 to move, place the splint 10 and the hook 7 on both sides of the bracket of the roller that needs to be positioned, and then tighten the screw rod 9, so that the screw rod 9 drives the anti-slip strip 13 on the splint 10 to clamp the components on the roller, thereby realizing the installation positioning of the device, and then insert the vertical rod 4 and the alarm 5 on the limit plate 3 into the inside of the limit groove, and tighten the bolt 14 to realize the installation of the alarm 5. When it is necessary to prevent the roller position of the roller from deviating to the bottom of the roadbed, when the roller 117 is on the roadbed, the roadbed squeezes the moving rod 111 on the roller 117, so that the slide plate 112 on the moving rod 111 moves upward, thereby separating the touch block 115 at the bottom of the slide plate 112 from the touch switch 116, and when the roller 117 is outside the edge of the roadbed. The terrain outside the edge of the roadbed is lower, which will produce a height difference. The roller 117 loses its supporting force, and the reset spring 114 resets the touch block 115 on the slide plate 112 downward, and then causes the touch block 115 to squeeze the touch switch 116, thereby causing the alarm 5 to sound an alarm, thereby reminding the driver that the roller on the corresponding side of the roller has reached the edge and needs to correct the direction in time. If the road is rebuilt and paved, the original curbstones on both sides will be higher than the roadbed. At this time, the parameters of the distance sensor 118 need to be set so that the sensing distance of the distance sensor 118 is set within a certain threshold. When the distance sensor 118 senses that the distance between the curbstone and the roadbed is less than the preset threshold of the distance sensor 118, the controller will also control the alarm 5 to sound an alarm, thereby reminding the staff to correct the direction of the roller in time to avoid damage to the curbstone.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
