Description
Technical Field
[0001] This utility model relates to the field of guardrail maintenance technology, and in particular to a guardrail cleaning device. Background Technology
[0002] In the field of guardrail cleaning, traditional manual cleaning methods suffer from low efficiency and inconsistent cleaning results, making it difficult to meet the needs of large-scale, high-efficiency cleaning. At the same time, although some mechanized cleaning devices exist on the market, they often have shortcomings such as unreasonable design and limited applicability, resulting in poor cleaning effects and even potential damage to the guardrails.
[0003] Specifically, in traditional cleaning methods, workers need to use hand cleaning tools to clean the guardrails section by section. This method is not only time-consuming and labor-intensive, but the cleaning effect is often affected by factors such as the worker's physical strength and skill level, making it difficult to guarantee the consistency and comprehensiveness of the cleaning. In addition, manual cleaning also poses safety hazards, especially on dangerous sections such as highways, where the safety of workers cannot be effectively guaranteed.
[0004] While existing mechanized cleaning devices have improved cleaning efficiency to some extent, they often suffer from poor design, resulting in insufficient stability during operation and a tendency to damage the guardrails. Furthermore, these devices often lack adaptability to guardrails of varying widths, necessitating frequent replacement of cleaning components with different specifications, significantly increasing operational difficulty and costs.

[0007] Optionally, the cleaning seat has vertically upward handles at the left and right ends of its top plane for supporting walking.
[0008] Optionally, nozzles for spraying towards the guardrail are provided vertically at even intervals on the opposite sidewalls of the two cleaning rods.
[0009] Optionally, a clamping wheel is fixedly installed at the lower end of the clamping rod, the vertical sidewall of the clamping wheel is tangent to the sidewall of the guardrail, a tension spring is connected between the upper ends of the two clamping rods on the end clamp seat at the head of the travel direction, a worm gear is fixedly installed at the upper ends of the two clamping rods at the tail of the travel direction, and a cleaning brush is fixedly connected downward at the lower ends of the two clamping rods at the tail of the travel direction, the cleaning brush contacting the guardrail during the rotation of the clamping rod.
[0010] Optionally, the adjustment frame has a horizontally rotating single-headed double-ended lead screw, and the lead screws at both ends of the double-ended lead screw are respectively connected to the corresponding drive sleeve blocks for rotation.

[0012] This utility model provides a guardrail cleaning device, which has the following beneficial effects:
[0013] First, the device achieves uniform distribution and spraying of the cleaning solution through the coordinated operation of an external cleaning pump and a cleaning distribution pipe. The cleaning solution is precisely delivered to the distribution branch pipe and, through evenly distributed nozzles on the cleaning rod, comprehensively covers the guardrail surface in a mist or columnar form, effectively removing stains and ensuring efficient and comprehensive cleaning results.
[0014] Secondly, the device's travel system employs symmetrically installed front and rear travel buffer bars and their lower support wheels, providing a stable travel path.

[0027] Example 1: Please refer to Figures 1 to 4 :
[0028] This utility model proposes a guardrail cleaning device, comprising: a cleaning seat 1; end clamps 5 fixedly installed at the front and rear ends of the cleaning seat 1; a cleaning diversion pipe 2 horizontally fixedly installed at the upper middle part of the cleaning seat 1, the upper middle part of the cleaning diversion pipe 2 being an inlet pipe 201 connected to an external cleaning pump, and diversion branch pipes 202 respectively provided at the bottom of both ends of the cleaning diversion pipe 2, with cleaning rods 3 vertically and downwardly fixedly connected to the lower ends of the diversion branch pipes 202, the two cleaning rods 3 being respectively located on both sides of the guardrail to be cleaned; two sets of walking buffer bars 4 symmetrically installed downwards on the front and rear of the cleaning seat 1, each set of walking buffer bars... A walking support wheel 401 is rotatably mounted between the lower ends of the punch rod 4. The lower end of the walking support wheel 401 abuts against the upper crossbar of the guardrail. A spring 402 is fitted on the walking buffer rod 4 between the walking support wheel 401 and the cleaning seat 1. An adjustment bracket 6 is provided on the end clamp 5 at the rear of the travel direction near the outer edge. The end clamp 5 has symmetrical movable slots 501 that pass through vertically. A vertical clamping rod 502 is provided in the movable slot 501. The two clamping rods 502 are respectively placed on both sides of the guardrail. A drive sleeve 7 is fitted on the clamping rod 502 above the end clamp 5 at the rear of the travel direction.
[0029] Among them, the top plane of the cleaning seat 1 has vertical handles 101 at the left and right ends of the top plane for supporting walking.
[0030] Among them, the two cleaning rods 3 on the opposite side walls are vertically spaced and evenly provided with nozzles 301 for spraying towards the guardrail.
[0031] The lower end of the clamping rod 502 is fixedly installed with a clamping wheel 503. The vertical side wall of the clamping wheel 503 is tangent to the side wall of the guardrail. A tension spring 504 is connected between the upper ends of the two clamping rods 502 on the end clamping seat 5 at the head of the travel direction. The upper ends of the two clamping rods 502 at the tail of the travel direction are respectively fixedly provided with worm gears 505. The lower ends of the two clamping rods 502 at the tail of the travel direction are respectively fixedly connected downwards with cleaning brushes 506. The cleaning brushes 506 come into contact with the guardrail during the rotation of the clamping rods 502.
[0032] Among them, the adjusting frame 6 has a horizontally rotating single-headed double-ended lead screw 601, and the lead screws at both ends of the double-headed lead screw 601 are respectively connected to the corresponding drive sleeve block 7 for rotation.
[0033] In Embodiment 2, based on Embodiment 1, the left and right drive sleeve blocks 7 are connected by a drive insert shaft 701. The drive insert shaft 701 consists of a spline insert shaft and a spline bushing. A motor 703 is fixedly installed on the outside of one end of the drive sleeve block 7. The motor 703 is rotatably connected to the drive insert shaft 701. A worm gear 702 is provided on the drive insert shaft 701, and the drive insert shaft 701 meshes with the worm wheel 505.
[0034] The working principle of this embodiment:
[0035] After the device is started, cleaning fluid is first delivered to the inlet pipe 201 of the cleaning diversion pipe 2 via an external cleaning pump. After entering the cleaning diversion pipe 2, the cleaning fluid is evenly distributed to the branch pipes 202 at both ends, and then evenly sprayed onto the guardrail surface in the form of a mist or column through the nozzles 301 on the cleaning rod 3 connected to the bottom of the branch pipe 202. These nozzles 301 are evenly distributed vertically at intervals on the side wall of the cleaning rod 3 to ensure that the cleaning fluid can fully cover the guardrail and effectively remove stains.
[0036] Meanwhile, the device's movement relies on two sets of symmetrically installed walking buffer bars 4 at the front and rear of the cleaning seat 1, along with their lower walking support wheels 401. The walking support wheels 401 are in close contact with the upper crossbar of the guardrail, providing a stable path for the device. Springs 402 are fitted onto the walking buffer bars 4, providing shock absorption and cushioning, enabling the device to adapt to different road conditions and maintain smooth operation.
[0037] In terms of clamping and cleaning, the clamps 5 at both ends of the device clamp the guardrail through the clamping rods 502 in the movable slots 501. The clamping rods 502 at the head of the travel direction are connected by a tension spring 504 to provide initial clamping force, ensuring a tight fit between the device and the guardrail. The clamping rods 502 at the tail of the travel direction are connected to the drive sleeves 7 through a worm gear 505. These drive sleeves 7 are connected by a drive insert shaft 701 to form an integrated drive system. The drive insert shaft 701 consists of a spline insert shaft and a spline bushing. This design facilitates torque transmission while maintaining structural compactness.
[0038] When the motor 703 starts, it drives the worm gear 702 to rotate via the drive sleeve shaft 701. The worm gear 702 then meshes with the worm wheel 505, driving the clamping rod 502 and the cleaning brush 506 at its lower end to rotate. As the clamping rod 502 rotates, the cleaning brush 506 makes close contact with the guardrail, further scrubbing the guardrail surface and enhancing the cleaning effect. Simultaneously, the clamping wheel 503 at the lower end of the clamping rod 502 is tangential to the side wall of the guardrail, not only serving a guiding function but also assisting in cleaning the side wall of the guardrail during rotation.
[0039] Furthermore, the double-ended lead screw 601 on the adjustment frame 6, through rotational connection with the corresponding drive sleeve 7, allows for fine-tuning of the position of the clamping rod 502, thus adapting to guardrails of different widths. This design not only improves the applicability of the device but also ensures stability and consistency of cleaning results during the cleaning process.
