Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning equipment technology, specifically a high-pressure cleaning mechanism for highway maintenance. Background Technology

[0002] In routine highway maintenance, high-pressure water washing is a means of removing surface dust and debris. Existing vehicle-mounted cleaning devices generally use fixed spray booms: the cleaning width of fixed spray booms is not adjustable, and the entire boom must extend outwards during driving, severely reducing vehicle passability; although folding designs exist, the existing folding mechanisms lack buffering and limiting at extreme positions. During emergency braking or external collisions, the connecting rods are prone to over-extension and compression, causing malfunctions such as push rod bending. Extensive research has been conducted on this issue. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a high-pressure cleaning mechanism that can greatly expand the cleaning range during operation, can be folded and hidden under the vehicle to enhance passability, and at the same time has the functions of buffer protection and convenient maintenance.

[0004] This utility model is achieved through the following technical solution: A high-pressure cleaning mechanism for highway maintenance includes a base, an electric push rod rotatably disposed within the base, a telescopic push rod disposed within the electric push rod, and a connecting block fixed at the end of the push rod. The mechanism is characterized in that a first connecting rod rotatably disposed at the end of the base away from the electric push rod, a second connecting rod rotatably disposed within the first connecting rod, the push rod and the second connecting rod being rotatably connected, multiple nozzles fixed within the first and second connecting rods, a stop block assembly abutting against the first connecting rod disposed within the base, a roller assembly disposed at the end of the second connecting rod, and a limiting assembly limiting the abutment against the second connecting rod disposed within the first connecting rod.

[0005] In a further technical solution, the electric push rod has a first shaft fixed at both ends, and the first shaft is rotatably connected to the base.

[0006] In a further technical solution, a first inner cavity is provided inside the first connecting rod, and a second inner cavity is provided inside the second connecting rod, with the connecting block rotatably connected to the second inner cavity.

[0007] In a further technical solution, the nozzle is fixedly disposed within the first inner cavity and the second inner cavity.

[0008] In a further technical solution, a vertical plate is fixed to the top of the base, and a mounting plate is fixed to the top of the vertical plate. The mounting plate is used to connect and fix to the bottom of the vehicle body.

[0009] In a further technical solution, a second shaft is fixed at both ends of the first connecting rod, and the second shaft is rotatably connected to the base.

[0010] A further technical solution includes a stop assembly comprising a fixed plate fixed within the base, a slide rail fixed to the front and rear ends of the right side of the fixed plate, a slider slidably mounted on the slide rail, a pad detachably fixed within the slider, a threaded rod fixed to the left side of the slider, the threaded rod passing through the fixed plate, and two anti-loosening nuts threadedly connected to the outer surface of the threaded rod, the anti-loosening nuts abutting against the fixed plate.

[0011] A further technical solution includes a roller assembly comprising a third shaft fixed to the upper and lower sides of the end of the second connecting rod, wherein a roller is rotatably disposed on the outer surface of the third shaft.

[0012] A further technical solution includes a fixing block fixed to the front end of the first connecting rod, wherein the fixing block is provided with an abutting cavity.

[0013] The beneficial effects of this utility model are as follows: First, by rotatably installing an electric push rod at one end of the base, the push rod inside the electric push rod is rotatably connected to the second inner cavity of the second connecting rod, and the first connecting rod is rotatably connected to the base, and the second connecting rod is rotatably connected to the first connecting rod. After the push rod extends out of the electric push rod, it drives the first connecting rod and the second connecting rod to fold and unfold. In the unfolded state, the nozzles in the first connecting rod and the second connecting rod spray a wider cleaning area. When folded, it is stored under the vehicle body, increasing the vehicle's passability.

[0014] Second, a replaceable pad is provided on one side of the first connecting rod. In the folded state, since the first connecting rod abuts against the pad, when an external force compresses the connecting rod structure, it can prevent the first connecting rod from further folding and deforming, thus reducing the impact on the electric push rod.

[0015] Third, regarding the second link, after it is deployed, since the push rod extends and retracts within the electric push rod, the fixing block only limits the second link. If the second link is pulled further, the fixing block will limit the second link to prevent the push rod from being pulled further out of the electric push rod and reduce the impact on the electric push rod.

[0016] Fourth, two anti-loosening nuts are provided on the threaded rod, which can fix the threaded rod in the fixed plate to maintain the position of the pad and the slider, so that the first connecting rod can abut against the pad when folded, and also take into account the function of personnel being able to replace the pad after the slider slides.

Figure 1The projection relationship of this utility model is consistent in the up, down, left, right, front, and back directions. A high-pressure cleaning mechanism for highway maintenance includes a base 18. An electric push rod 21 is rotatably mounted inside the base 18. A telescopic push rod 41 is mounted inside the electric push rod 21. A connecting block 42 is fixed to the end of the push rod 41. A first connecting rod 25 is rotatably mounted at the end of the base 18 away from the electric push rod 21. A second connecting rod 13 is rotatably mounted inside the first connecting rod 25. The push rod 41 extends into the second connecting rod 13 and rotatably engages with it. Multiple nozzles 16 are fixed inside the first connecting rod 25 and the second connecting rod 13. A stop assembly is provided inside the base 18 to abut against the first connecting rod 25 so that the first connecting rod 25 maintains a preset angle with the base 18 in the folded state. A roller assembly is provided at the end of the second connecting rod 13. A limiting assembly is provided inside the first connecting rod 25 to limit the second connecting rod 13 when it is unfolded relative to the first connecting rod 25.

[0020] Advantageously, the electric push rod 21 has a first shaft 19 fixed at both ends, and the first shaft 19 is rotatably connected to the base 18.

[0021] Advantageously, the first connecting rod 25 is provided with a first inner cavity 17, the second connecting rod 13 is provided with a second inner cavity 43, and the connecting block 42 is rotatably connected to the second inner cavity 43.

[0022] Advantageously, the nozzle 16 is fixedly disposed in the first inner cavity 17 and the second inner cavity 43, and the first connecting rod 25 and the mounting plate 23 are provided with through holes opposite to the nozzle 16 for passing through water pipes.

[0023] Advantageously, a vertical plate 22 is fixed to the top of the base 18, and a mounting plate 23 is fixed to the top of the vertical plate 22. The mounting plate 23 is used to connect and fix to the bottom of the vehicle body 61.

[0024] Advantageously, the first connecting rod 25 has a second shaft 24 fixed at both ends, and the second shaft 24 is rotatably connected to the base 18.

[0025] Advantageously, the stop assembly includes a fixed plate 33 fixed within the base 18. A slide rail 32 is fixed to the front and rear ends of the right side of the fixed plate 33. A slider 36 is slidably mounted on the slide rail 32. A pad 37 is fixed inside the slider 36 by fasteners. A threaded rod 34 is fixed to the left side of the slider 36. The threaded rod 34 passes through the fixed plate 33. Two anti-loosening nuts 35 are threadedly connected to the outer surface of the threaded rod 34. The anti-loosening nuts 35 abut against the fixed plate 33. By using a wrench to engage the anti-loosening nuts 35 on their outer surface and rotating them, the slider 36 can extend and retract between the slide rails 32, allowing the pad 37 to be replaced after it disengages from the first connecting rod 25.

[0026] Advantageously, the roller assembly includes a third shaft 11 fixed to the upper and lower sides of the end of the second link 13, and a roller 12 is rotatably disposed on the outer surface of the third shaft 11.

[0027] Advantageously, the limiting component includes a fixing block 14 fixed to the front end of the first connecting rod 25, and a mating cavity 51 is provided in the fixing block 14. After the second connecting rod 13 is fully rotated and unfolded, the second connecting rod 13 abuts against the mating cavity 51 and is limited.

[0028] Advantageously, it also includes a vehicle body 61, on which a water tank 65 is installed. A water pump 66 is connected to one side of the water tank 65, and a solenoid valve 67 is also connected to one side of the water pump 66. The solenoid valve 67 is connected to the nozzle 16. A power supply 64 is installed on the vehicle body 61. The power supply 64 is electrically connected to the solenoid valve 67, the water pump 66, and the electric push rod 21, so that the power supply 64 supplies power to the solenoid valve 67, the water pump 66, and the electric push rod 21. A controller 63 is also installed on the vehicle body 61. The controller 63 is electrically connected to the solenoid valve 67, the water pump 66, and the electric push rod 21, so that the controller 63 controls the solenoid valve 67, the water pump 66, and the electric push rod 21.

[0029] After the mechanism operates via the electric push rod 21, the connecting block 42 and the push rod 41 extend out of the electric push rod 21. Since the connecting block 42 is hinged to the second inner cavity 43, after the push rod 41 and the connecting block 42 are extended, the second connecting rod 13 and the first connecting rod 25 will rotate and unfold relative to the base 18. After water is supplied, the nozzle 16 will spray water downwards to clean the road. After the mechanism is folded, its folded projection is located below the vehicle body 61, which can improve the vehicle's passability.

[0030] In the folded state, the first link 25 abuts against the pad 37, and the push rod 41 retracts into the electric push rod 21. This is the initial position of the folded state.

[0031] Since the pad 37 will be impacted by the first link 25 during the folding and unfolding process, the pad 37 can be replaced by sliding the slider 36 on the slide rail 32 to release the pad 37 from the first link 25. Then, the pad 37 can be disassembled from the slider 36 and replaced with a new pad 37.

[0032] In the unfolded state, the second link 13 is pushed by the push rod 41 and unfolds relative to the first link 25. The abutting cavity 51 in the fixing block 14 is used to abut against the second link 13 to limit the second link 13.

[0033] Water tank 65 is used to supply water to water pump 66. After the water pump 66 is working, it pumps water to solenoid valve 67. After the solenoid valve 67 is opened, it supplies water to nozzle 16 to realize the function of spraying water for cleaning.

[0034] The electric actuator 21 features a power-off self-locking function, which maintains self-locking during power outages, improving structural stability.
