Description

Technical Field

[0001] This utility model relates to the field of guardrail filling, specifically to a road guardrail filling material guiding device. Background Technology

[0002] The central median, an important facility in highway traffic engineering, is set longitudinally along the centerline of the road and is mainly used to separate two-way traffic and improve driving safety. With the improvement of road safety standards, when the central median adopts a reinforced concrete guardrail structure with a higher protection level on both sides, this structure creates a median space between the two sides of the concrete guardrail, which needs to be filled with earthwork.

[0003] Currently, conventional backfilling operations mainly involve excavators or loaders directly dumping earthwork into the median strip. However, this method has significant drawbacks: due to the lack of effective material guiding and limiting devices, earthwork easily overflows from the top of the concrete guardrail during the backfilling process, causing not only material waste but also severe pollution of the road surface and increased road maintenance costs. Especially on busy roads such as urban expressways, overflowing earthwork poses safety hazards to passing vehicles, and cleanup work often requires traffic interruption, seriously affecting road traffic efficiency. Furthermore, existing backfilling methods cannot guarantee the flatness of the earthwork within the median strip, requiring secondary manual trimming later, further increasing construction time and labor costs. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a road guardrail filling and guiding device.

[0005] This utility model is achieved through the following technical solution:

[0006] This application provides a road isolation guardrail filling material guiding device, including a support frame that can be moved and supported on the concrete guardrails on both sides of the road isolation strip. The upper part of the support frame is supported by an outwardly extending material guiding box, and the rear end of the support frame is equipped with a scraper for cleaning and leveling the filling soil of the isolation strip.

[0007] Furthermore, this application also proposes that the support frame is equipped with multiple support guide wheels that support the outside and top of the corresponding concrete guardrail.

[0008] Furthermore, this application also proposes that the support frame is equipped with transverse supports and extension supports on both sides for supporting the two sides of the guide box.

[0009] Furthermore, this application also proposes that the material guide box includes a long material guide trough and a short material guide trough that are inclined inwards towards the isolation zone on both sides, and the outer sides of the long material guide trough and the short material guide trough are fixedly connected by a connecting frame.

[0010] Furthermore, this application also proposes that the scraper includes a transverse scraper located above the isolation strip, and that the two sides of the transverse scraper are integrally provided with inclined plates extending towards the top of the concrete guardrail, and that the ends of the inclined plates are fixed with posts, which are inserted into the longitudinal sliding sleeves fixed by the support frame.

[0011] Furthermore, this application also proposes that the longitudinal sleeve side has a strip-shaped opening for passing through the inclined plate of the scraper.

[0012] Furthermore, this application also proposes that the lower part of the inclined plate of the scraper is connected to a cleaning brush for cleaning the upper part of the concrete guardrail.

[0013] Compared with existing technologies, the advantages of this utility model are: by using the support frame and the guide box together, this utility model can effectively guide the earthwork material to fall accurately into the isolation zone, preventing the material from overflowing and polluting the road surface. At the same time, the design of the scraper plate ensures the flatness after filling, and has the advantages of high construction efficiency, less material waste and good safety.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1-2 As shown, this application proposes a road isolation guardrail filling material guiding device, including a support frame that can be moved and supported on the concrete guardrails on both sides of the road isolation strip. The upper part of the support frame is supported by an outwardly extending material guiding box, and the rear end of the support frame is equipped with a scraper for cleaning and leveling the filling soil of the isolation strip.

[0019] Specifically, the support frame can be welded from steel, and its bottom can be equipped with height-adjustable casters to accommodate concrete guardrails of different heights. The material guide box can be designed as a split structure, connected and fixed to the support frame with bolts for easy transportation and installation. The scraper is installed at the rear end of the support frame, and it uses its own weight to press against the upper part of the concrete guardrail to scrape the material.

[0020] This technical solution, through the use of a movable support frame and a material guide box, effectively controls the placement and range of the filling material, preventing spillage and road surface pollution. The extended design of the material guide box allows filling operations to be carried out outside the guardrail, increasing the filling area and preventing material spillage. Furthermore, the scraper blades simultaneously level the filling material, improving construction efficiency. Compared to existing technologies, this device has a simple structure, is easy to operate, and significantly reduces material waste and road surface pollution during the filling process.

[0021] Furthermore, this application also proposes that the support frame is equipped with multiple support guide wheels that support the outside and top of the corresponding concrete guardrail.

[0022] Specifically, the support guide wheels can be rubber-coated steel rollers, preferably with a diameter of 100-200mm and a wheel width of 50-80mm. As a preferred embodiment, each concrete guardrail has two horizontally arranged support guide wheels on its side and two to four horizontally arranged support guide wheels on its top. Furthermore, the support guide wheels are fixed to the support frame via height-adjustable mounting seats, wherein the adjustment mechanism can employ a threaded rod with a locking nut. The contact surface between the support guide wheels and the concrete guardrail can be provided with anti-slip textures, with a texture depth of 1-2mm.

[0023] Therefore, this technical solution achieves stable movement of the device through multi-directionally arranged support guide wheels. The support guide wheels provide vertical restraint on the outside of the concrete guardrail and horizontal load-bearing at the top, effectively preventing lateral tilting or deviation during movement. Specifically, the outer support guide wheels bear lateral forces, while the top support guide wheel bears the main load; their combined action ensures smooth sliding of the device along the guardrail. Compared to relying solely on frame support, this design significantly reduces movement resistance, avoids direct friction between the frame and the concrete guardrail, and achieves precise guidance of the device through wheeled support.

[0024] Furthermore, this application also proposes that the support frame is equipped with transverse supports and extension supports on both sides for supporting the two sides of the guide box.

[0025] The transverse support and extension support can be implemented in various structural forms. The transverse support can be welded from L-shaped angle steel or channel steel, and the extension support is fixed diagonally upwards towards the support frame to support the longer guide trough. In specific implementation, the transverse support consists of two horizontal bars supported diagonally below the short guide trough of the guide box.

[0026] This technical solution effectively solves the problem of lateral swaying of the material guide box caused by the impact of excavated material during operation by setting transverse supports and extended supports on both sides of the supporting frame. The transverse supports provide support for the short material guide troughs, while the extended supports effectively support the longer material guide troughs, forming a stable triangular support structure together. Compared with the existing technology that relies solely on top support, this structure significantly improves the stability of the material guide box, avoids the spillage of excavated material caused by box swaying, and thus ensures the continuity and accuracy of the filling operation.

[0027] Furthermore, this application also proposes that the material guide box includes a long material guide trough and a short material guide trough that are inclined inwards towards the isolation zone on both sides, and the outer sides of the long material guide trough and the short material guide trough are fixedly connected by a connecting frame.

[0028] The inclination angles of the long and short material guide chutes can be adjusted according to actual construction needs, for example, using inclination angles from 30° to 60°. The different lengths allow for better excavator bucket operation and personnel observation when receiving materials from the excavator. The connecting frame can be welded to the long and short material guide chutes. The cross-sectional shape of the long and short material guide chutes can be designed as a frame. Furthermore, the inner surfaces of the long and short material guide chutes can be coated with a wear-resistant coating to extend their service life.

[0029] This technical solution, by incorporating inclined long and short guide chutes, effectively guides excavated material into the median strip, reducing the risk of spillage. The connecting frame ensures the structural stability of the guide box, maintaining its normal operation during movement. Compared to existing technologies, this solution significantly reduces road surface contamination from excavated material, improving construction efficiency and cleanliness. Specifically, the inclined guide chutes utilize gravity to achieve automated excavated material transport, reducing the need for manual intervention.

[0030] Furthermore, this application also proposes a specific structure for the scraper. The scraper includes a transverse scraper located above the isolation strip, and inclined plates extending towards the top of the concrete guardrail are integrally provided on both sides of the transverse scraper. The ends of the inclined plates are fixed with posts, which are inserted into the longitudinal sliding sleeves fixed by the support frame.

[0031] The transverse scraper is used to level the backfill soil within the isolation strip, while the inclined design allows for better cleaning of the earthwork above the concrete guardrail. The cooperation between the insert post and the longitudinal sliding sleeve enables adjustable installation of the scraper. The longitudinal sliding sleeve can be made of metal and may have an internal wear-resistant bushing to reduce friction. The insert post can be cylindrical, with a limiting structure at the top to prevent detachment. The connection between the inclined plate and the transverse scraper can be achieved through welding or integral molding.

[0032] This technical solution achieves effective leveling and cleaning of the fill soil in the median strip by optimizing the structural design of the scraper blade. The transverse scraper blade can level the earthwork material and prevent overflow; the inclined plate design allows the scraper blade to better fit the concrete guardrail; and the cooperation between the insert post and the longitudinal sliding sleeve provides convenience for installation and adjustment. Compared with existing technologies, this solution can more effectively control the filling quality of earthwork material, reduce road pollution, and improve construction efficiency and equipment adaptability.

[0033] Furthermore, this application also proposes that the longitudinal sleeve side has a strip-shaped opening for passing through the inclined plate of the scraper.

[0034] Specifically, the strip-shaped opening design on the side of the longitudinal sleeve allows the inclined plate of the scraper to move within the longitudinal sleeve while avoiding interference between the inclined plate and the longitudinal sleeve. The width of the strip-shaped opening is slightly larger than the thickness of the inclined plate to ensure smooth sliding. As a preferred embodiment, the strip-shaped opening can extend along the length of the longitudinal sleeve, allowing the scraper to be adjusted up and down within a certain range.

[0035] To address this issue, the technical solution of this application utilizes a strip-shaped design to ensure the inclined plate of the scraper blade can be stably inserted into the longitudinal sliding sleeve, maintaining the scraper blade's flexible adjustment capability during earthwork filling. Because the inclined plate can move freely along the longitudinal sliding sleeve, the scraper blade can adapt to the filling needs of isolation strips at different heights, effectively reducing the problem of earthwork overflowing from the concrete guardrail. Compared with existing technologies, this solution not only improves the adjustment accuracy of the scraper blade but also reduces mechanical wear during operation, enhancing the reliability and service life of the equipment.

[0036] Furthermore, this application also proposes that the lower part of the inclined plate of the scraper is connected to a cleaning brush for cleaning the upper part of the concrete guardrail.

[0037] The cleaning brush is made of wear-resistant steel wire and is fixed to the bottom edge of the inclined plate with bolt clips. The bristle length of the cleaning brush is preferably 3-5 cm to ensure full contact with the top curved surface of the concrete guardrail.

[0038] This technical solution adds a cleaning brush below the inclined plate of the scraper, which automatically removes residual soil adhering to the top of the concrete guardrail while leveling the filling soil of the median strip. As the device moves along the median strip, the inclined plate drives the cleaning brush to continuously scrape the top of the guardrail, effectively preventing soil from overflowing from the outside of the guardrail. Compared with technical solutions that rely solely on the scraper, this design achieves simultaneous filling and cleaning operations, avoiding the problem of secondary pollution of the road surface. The flexible nature of the cleaning brush ensures cleaning effectiveness without damaging the guardrail surface.

[0039] The implementation principle of a road guardrail filling and guiding device according to an embodiment of this application is as follows:

[0040] The excavator scoops up the earthwork from the transport vehicle and dumps it onto the upper part of the guide box. The earthwork then slides down the inclined surface of the guide trough 7 and guide trough 8 to fill the lower isolation zone 2. After partial filling, the excavator bucket pushes the support frame 3 forward. Simultaneously, the scraper blade 10 at the rear scrapes the protruding earthwork within the isolation zone 2, while the cleaning brush 13 at the bottom of the inclined blade sweeps away the earthwork spilled on the concrete guardrail 1, guiding it along the inclined blade into the isolation zone 2. This ensures a smooth surface while effectively preventing earthwork from overflowing from the outside of the guardrail. Furthermore, because the scraper blade 10 is in contact with the surface of the concrete guardrail 1, it effectively prevents the device from moving arbitrarily on the concrete guardrail 1, ensuring the stability of the loading process.
