Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning device for bridge guardrails used in bridge engineering. Background Art

[0002] With the continuous development of transportation infrastructure, bridges occupy an important position in modern transportation. As an important facility to ensure traffic safety, the cleaning condition of bridge guardrails directly affects the overall image and safety of use of bridges. In previous practices, the cleaning of bridge guardrails mainly relied on manual work, which was not only inefficient, but also faced the risk of high-altitude operations for workers. At the same time, the quality of manual cleaning was difficult to ensure uniformity and thoroughness. In addition, manual cleaning requires a lot of manpower, material and time resources, which is costly for large-scale bridge guardrail cleaning tasks. In order to improve this situation, some preliminary mechanized cleaning equipment has gradually emerged. However, these equipment still have defects. In the mechanized cleaning process, roller brushes are generally used to directly brush the guardrails. However, due to the different thickness and height of the bridge guardrails, the roller brushes are not in close contact with the guardrails. Especially when encountering thickened bridge guardrails, the general roller brushing process is extremely difficult. Based on this, we designed a cleaning device that can adjust the distance between the two roller brushes to adapt to the cleaning of bridge guardrails of different thicknesses and types. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the utility model provides a cleaning device for bridge guardrails used in bridge engineering, which can adjust the distance between symmetrically arranged roller brushes to facilitate the cleaning of bridge guardrails of different thicknesses.

[0004] The technical implementation scheme of the utility model is:

[0005] A cleaning device for a bridge guardrail used in a bridge project comprises a fixing groove, an adjusting mechanism and a cleaning mechanism.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0024] like Figure 1-5 As shown, a cleaning device for a bridge guardrail used in a bridge engineering project includes a fixed groove 7, an adjusting mechanism 1 and a cleaning mechanism 6. The fixed groove 7 is a rectangular hollow structure with an upper opening, and the fixed groove 7 is connected to the cleaning mechanism 6 through the adjusting mechanism 1; the adjusting mechanism 1 includes a screw 105, a first drive motor 102, an adjusting nut 106, a connecting rod 107 and a pushing rod 108, the adjusting nut 106 is connected to the screw 105 inside the fixed groove 7, and both sides of the adjusting nut 106 are connected to the cleaning mechanism 6 through the connecting rod 107 and the pushing rod 108; the cleaning mechanism 6 includes a driving box 601, a chain 604, a first sprocket 603 and a cleaning roller 602, a plurality of cleaning rollers 602 are arranged at the bottom of the driving box 601, the first sprocket 603 on the rotating shaft of the cleaning roller 602 is connected to the second sprocket through the chain 604 to form a transmission structure, and a sealing shell 605 and a second driving motor 606 are arranged on the upper part of the driving box 601.

[0025] It should be noted that bridge guardrails, as important components on bridges, play a protective and aesthetic role. There is a lot of dust on the road surface, and the dust flying from cars passing by will adhere to the guardrails. If it is not removed, it will affect the appearance of the city. However, the existing bridge guardrails are generally cleaned manually or mechanically. Manual cleaning requires high labor intensity and is not efficient. The existing mechanical cleaning method cannot clean guardrails of different sizes and models. Based on this, we designed a cleaning equipment that can adjust the spacing between cleaning rollers to adapt to guardrails of different sizes.

[0026] It should be further explained that, in order to achieve cleaning, we have symmetrically arranged cleaning mechanisms 6 on both sides of the fixed groove 7, wherein the cleaning rollers 602 inside the drive box 601 can be rotated under the drive of the second drive motor 606 to complete the cleaning work, and the entire cleaning mechanism 6 can be adjusted by the adjustment mechanism 1 to control the spacing between the cleaning rollers 602, so as to adapt to the use of bridge guardrails of different widths.

[0027] It needs to be further explained that, in order to realize the advancement and adjustment of the entire drive box 601 together with the cleaning roller 602, we set an adjusting nut 106 inside the fixed groove 7, and multiple adjusting nuts 106 are set on the upper part thereof, and the two sides of the adjusting nut 106 are connected by a connecting rod 107 and a propulsion rod 108, so that it can move under the rotation of the screw rod 105, and the propulsion rod 108 is pushed during the movement, thereby advancing and adjusting the entire drive box 601, and completing the adjustment of the spacing of the cleaning roller 602 in this process.

[0028] like Figure 1-Figure 5 As shown, one end of the connecting rod 107 is movably connected to the fixing ear of the adjusting nut 106, and the other end of the connecting rod 107 is movably connected to the connecting hole at one end of the pushing rod 108; the pushing rod 108 is arranged in the through hole 109 of the fixing groove 7, and a connecting ring is arranged on the other end of the pushing rod 108; a first driving motor 102 is arranged at one end of the fixing groove 7, and the output shaft of the first driving motor 102 is connected to the screw 105 through a coupling; the output shaft of the second driving motor 606 is connected to the rotating shaft on the cleaning roller 602 through a coupling.

[0029] It should be noted that the screw rod 105 is driven by the first drive motor 102 to rotate, thereby driving the adjusting nut 106 to move. During this process, the connecting rod 107 can push the propulsion rod 108 to move, thereby realizing the propulsion of the entire drive box 601.

[0030] like Figure 1-Figure 3As shown, a spray assembly 5 is also included, and the spray assembly 5 includes a connecting bracket 501, a spray pipe 502 and a three-way connecting pipe 503. The spray pipe 502 is arranged on the upper part of the fixing groove 7 through the connecting bracket 501. The spray pipe 502 is connected to the connecting bracket 501 through a connecting ring. A three-way connecting pipe 503 is arranged on the spray pipe 502, and the three-way connecting pipe 503 is connected to the diversion pump 3 through the water guide pipe 4; a plurality of spray holes are arranged on the spray pipe 502, and a spray head is arranged in each of the spray holes.

[0031] It should be noted that in order to improve the cleaning efficiency, a spray assembly 5 is designed. The spray water is introduced into the spray pipe 502 through the diversion pump 3 and the water pipe 4, and then sprayed through the nozzle on the spray pipe 502. Combined with the cleaning roller 602 for brushing, the cleaning efficiency can be improved.

[0032] like Figure 1-Figure 3 As shown, a cover plate 8 is provided at the upper opening of the fixing groove 7, and a connecting slot 9 is provided on the cover plate 8.

[0033] It should be noted that a connecting slot 9 is provided on the upper portion of the cover plate 8 to facilitate docking with the connecting end of a cleaning vehicle and cooperate with the cleaning vehicle to complete all-round cleaning of the bridge guardrail.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
