Description

Technical Field

[0001] This invention relates to the field of highway maintenance equipment technology, and in particular to a highway drainage ditch cleaning device. Background Technology

[0002] Highway drainage ditches are important transportation infrastructure. Their smooth flow and cleanliness are crucial for ensuring timely rainwater drainage, preventing road flooding, ensuring vehicle safety, and avoiding environmental pollution and roadbed erosion and collapse. Currently, the cleaning and maintenance of drainage ditches mainly rely on manual labor or a combination of manual and mechanical methods. Manual cleaning not only requires the establishment of work protection zones, affecting normal road traffic, but also poses significant safety hazards. Furthermore, it suffers from slow cleaning speed, low efficiency, and high maintenance costs.

[0003] Furthermore, existing related machinery and equipment also have significant limitations. Many cleaning devices on the market are suspended designs, requiring attachment to other vehicles or equipment and unable to operate independently. However, in actual highway maintenance, a large number of drainage ditches (especially those on highways) are often located on both sides of the roadbed, far from the road surface, and some are even located at the bottom of slopes or other inaccessible areas. Traditional large or suspended equipment, limited by their size, weight, and maneuverability, cannot directly enter these ditches for operation, resulting in many sections of drainage ditches still relying on primitive manual cleaning methods, failing to achieve efficient, mechanized maintenance operations.

[0004] Therefore, there is an urgent need for a specialized automated device that can autonomously enter the interior of drainage ditches and carry out efficient cleaning operations, in order to solve the problems of low operating efficiency, poor safety, high cost, and insufficient adaptability to special terrain and ditch bodies in existing technologies.

[0025] In the optional embodiments of this example, a preferred embodiment is that there are two tracks 301. The first drive mechanism includes a battery pack 303 and a first drive motor 302 corresponding to each track 301. The first drive motor 302 drives the corresponding track 301 to rotate. The first drive motor 302 and the battery pack 303 are fixed to the support platform. By using two independent first drive motors 302 to drive the left and right tracks 301 respectively, good differential steering capability is achieved, enhancing maneuverability within the drainage ditch.

[0027] In this embodiment, the main functional modules of the equipment (walking assembly 3, support assembly 4, garbage lifting assembly 1, sweeping assembly 2, and unloading assembly 5) are designed with a quick plug-in / socket connection method. This allows the bulky overall equipment to be quickly disassembled into several independent modules that are easy to carry by manpower. This facilitates rapid assembly after transporting the equipment to hard-to-access drainage ditch locations such as below highway slopes. This greatly expands the equipment's operating range and terrain adaptability, overcoming the bottleneck that large or suspended equipment cannot directly enter the ditch for operation. The quick-release connection of each functional module also facilitates equipment maintenance and component replacement.

[0028] In the optional solutions of this embodiment, a more preferred option is to include a control box 402 fixed on the support frame 401, which is used to control the operation of the first drive mechanism, the second drive mechanism and the third drive mechanism.

[0029] In an optional embodiment, the second driving mechanism preferably includes a second driving motor 121 for driving the drive shaft 103 of the conveyor belt 101 to rotate. The conveyor belt 101 is wound around the drive shaft 103 and the driven shaft 120. When the drive shaft 103 rotates, it will drive the conveyor belt 101 to rotate around the drive shaft 103 and the driven shaft 120.

[0030] In the optional embodiments of this example, more preferably, there are two guide rails 118, and one fixed beam 112 corresponds to each guide rail 118. The fixed beam 112 slides in cooperation with the corresponding guide rail 118. Each guide rail 118 is provided with an insert plate, the length direction of which is the same as the length direction of the guide rail 118. The fixed beam 112 is provided with a groove 113 corresponding to the insert plate on the corresponding guide rail 118, and the insert plate slides in cooperation with the corresponding groove 113. The fixed beam 112 is provided with a pulley 119 that rolls in cooperation with the guide rail 118.

[0031] In a preferred embodiment, the lifting drive assembly includes a first U-shaped frame 114, a second U-shaped frame 115, a ratchet 125, a pawl 124, a positioning pin 123, and a steel cable 117. The first U-shaped frame 114 is fixedly connected to the first support 106, and the second U-shaped frame 115 is fixedly connected to the fixed beam 112. The ratchet 125 is rotatably connected to the first U-shaped frame 114 via a rotating shaft 116, and a first handle 126 is fixedly mounted on the ratchet 125. The pawl 124 is fixedly connected to a rotating shaft 133, which is rotatably connected to the first U-shaped frame 114. A fixed cylinder 128 is fixedly mounted on the pawl 124, and the positioning pin 123 passes through the fixed cylinder 128 and the pawl 124. The axial direction of the fixed cylinder 128 is parallel to the axial direction of the rotating shaft 133, and the positioning pin 123 can slide relative to the fixed cylinder 128 and the pawl 124. A second handle 122 is fixedly connected to the pin 123. The second handle 122 is perpendicular to the positioning pin 123. A gap 137 is provided on the side wall of the fixed cylinder 128 corresponding to the second handle 122. The second handle 122 can move within the gap 137. A first slot 131 and a second slot 132 are provided on the edge of the gap 137 corresponding to the second handle 122. A first spring 129 is sleeved on the positioning pin 123. One end of the first spring 129 abuts against the second handle 122, and the other end abuts against the fixed cylinder 128. An arc-shaped positioning groove 127 and a positioning hole 135 located in the positioning groove 127 are provided on the first U-shaped frame 114 corresponding to the positioning pin 123. A second fixed shaft 134 is also fixed on the first U-shaped frame 114. The second fixed shaft 134 is connected to the fixing ring 136 on the pawl 124 through the second spring 130. When the second handle 122 engages with the first slot 131, the positioning pin 123 extends into the positioning hole 135, and the pawl 124 separates from the ratchet 125; when the second handle 122 engages with the second slot 132, the positioning pin 123 exits the positioning hole 135, the positioning pin 123 slides into the positioning groove 127, and the pawl 124 engages with the ratchet 125 under the elastic force of the second spring 3.1; one end of the steel cable 117 is connected to the rotating shaft 116, and the other end is connected to the second U-shaped frame 115. When the pawl 124 engages with the ratchet 125, it provides a reliable one-way locking mechanism, preventing slippage due to gravity or vibration during operation. By actuating the second handle 122, the second handle 122 can drive the positioning pin 123 to slide relative to the fixed cylinder 128 and the pawl 124. If the positioning pin 123 extends into the positioning hole 135 and the second handle 122 engages with the first slot 131, the pawl 124 is separated from the ratchet 125, and the second handle 122 engages with the first slot 131. Under the action of locking, the pawl 124 and the ratchet 125 remain separated. At this time, bidirectional free adjustment can be achieved by manually turning the first handle 126. This ensures the stable and adjustable ground pressure of the sweeping component to optimize the sweeping effect, and also allows the component to be lifted as a whole to improve the equipment's passability when not in operation. Through the lifting drive assembly consisting of the ratchet 125, pawl 124, second handle, positioning pin and steel cable 117, the overall ground clearance of the sweeping assembly 2 and the garbage lifting assembly 1 can be manually and precisely adjusted.

[0032] In the optional schemes of this embodiment, the discharge port 213 is preferably a gathering plate structure, and the cross-sectional width of the discharge port 213 gradually decreases towards the conveyor belt 101; the discharge port 213 of the cleaning assembly 2 adopts a gathering plate structure with a gradually decreasing cross-section, which can effectively concentrate the garbage swept up by the roller brush 203 and guide it into the conveyor belt 101, solving the problem that garbage is easy to splash and difficult to collect in the narrow space of the trench; The conveyor belt 101 is a conveyor belt 101 with side guards; the conveyor belt 101 of the garbage lifting assembly 1 adopts a side guard design, and together with the anti-leakage bottom plate 105 located below the conveyor belt 101, it prevents sludge, debris and other garbage from leaking from the sides and bottom during the lifting process, ensuring that the garbage is completely transported to the unloading hopper 502.

[0033] The unloading guide 503 is hinged to the outlet of the unloading hopper 502 via a pin 504, and the unloading guide 503 can be flipped. The unloading guide 503 of the unloading assembly 5 is hinged to the unloading hopper 502 via a pin 504, and can be flipped, thereby flexibly controlling the direction and position of the waste discharge.

[0034] In a preferred embodiment, the cover 202 is fixedly provided with two parallel and spaced connecting plates 216. The second bracket 201 is provided with a first fixed shaft 214, which is rotatably connected to the second bracket 201 via two bearings. Both connecting plates 216 are fixedly sleeved on the first fixed shaft 214, and the two bearings are respectively mounted on bearing seats 215 on the second bracket 201. The cover 202 is also connected to the second bracket 201 via a telescopic rod 217. The grounding pressure of the roller brush 203 can be adjusted by changing the length of the telescopic rod 217. The cover 202 in the sweeping assembly 2 is connected to the second bracket 201 via the telescopic rod 217 (i.e., the adjustable length connecting rod), which allows for convenient adjustment of the grounding pressure of the roller brush 203 to adapt to different types of waste and ditch conditions, ensuring sweeping quality.

[0035] In the optional embodiments of this example, a preferred embodiment includes a third drive mechanism comprising a third drive motor 204 and an intermediate drive shaft 209. The third drive motor 204 is fixedly mounted on two connecting plates 216, and the intermediate drive shaft 209 is rotatably coupled to the two connecting plates 216. The third drive motor 204 is connected to the intermediate drive shaft 209 via a belt drive mechanism, and the intermediate drive shaft 209 is connected to the roller brush 203 via a chain drive mechanism 211.

Belt 207 and driven pulley 208, drive pulley 206 is fixed on drive pulley shaft 205, one end of drive pulley shaft 205 is fixedly connected to the output shaft of third drive motor 204, driven pulley 208 is fixedly sleeved on intermediate transmission shaft 209; chain 211 transmission mechanism includes drive sprocket 210, chain 211 and driven sprocket 212, drive sprocket 210 is fixedly sleeved on intermediate transmission shaft 209, driven sprocket 212 is fixedly sleeved on the rotating shaft of roller brush 203.

[0036] The specific working principle of the highway drainage ditch cleaning equipment in this embodiment is as follows: (1) First stage: Equipment preparation and attitude adjustment Since the target work area—highway drainage ditches (especially highway side ditches)—is often located below the roadbed slope, large equipment cannot directly reach it. Therefore, this equipment is first deployed using its modular quick-release design. The operators transport the five modules—walking assembly 3, support assembly 4, garbage lifting assembly 1, sweeping assembly 2, and unloading assembly 5—to the edge of the ditch, and then quickly assemble them by plugging and connecting them with the pre-set sleeves and connectors (such as the first to fifth sets / connector groups) on each module. For example, the support frame 401 of the support assembly 4 is aligned with and inserted into the connector on the support platform of the walking assembly 3 through the connector at its bottom; the sweeping assembly 2 is inserted into the corresponding connector at the front end of the garbage lifting assembly 1 through the connector on its bracket. The whole process does not require complicated tools, the connection is reliable, and the equipment can be reassembled on-site in the narrow ditch.

[0037] After the equipment is placed at the bottom of the trench, the operator starts the system through the control box 402 on the support assembly 4. First, according to the specific conditions of the trench bottom (such as the thickness of the garbage and the flatness of the trench bottom), the operator adjusts the height of the working parts off the ground through the lifting drive assembly. The specific operation is as follows: the operator moves the second handle 122 on the lifting drive assembly, which drives the positioning pin 123 to slide relative to the fixed cylinder 128 and the pawl 124, so that the positioning pin 123 extends into the positioning hole 35, and the second handle 122 engages with the first slot 131. Under the engagement of 122 and the first slot 131, the pawl 124 and ratchet 125 remain separated. Even if the pawl 124 and ratchet 125 are temporarily separated (unlocked), the first handle 126 is then turned. The first handle 126 drives the ratchet 125 to rotate, winding or releasing the steel cable 117 connected to the second U-shaped frame 115. Under the traction of the steel cable 117, the second U-shaped frame 115 and the fixed beam 112 slide along the guide rail 118 on the first bracket 106 via the pulley 119 on it, thereby driving... The garbage lifting assembly 1 (including the conveying housing 102) fixed to the fixed beam 112 and the sweeping assembly 2 connected to the front end of the garbage lifting assembly 1 rise or fall as a whole; after adjusting to a suitable height, the second handle 122 on the lifting drive assembly is moved so that the second handle 122 engages with the second slot 132, so that the positioning pin 123 disengages from the positioning hole 135, and the pawl 124 remains engaged with the ratchet 125 under the action of the elastic force (i.e., thrust) of the second spring 130, and in the engaged state In this state, when the ratchet 125 rotates in the transmission direction, it can overcome the elastic force of the second spring 130, causing the second spring 130 to compress, thus preventing unidirectional transmission. Moreover, under the meshing action of the ratchet 125 and the pawl 124, the ratchet 125 cannot be manually rotated in the transmission direction. This step can achieve two purposes simultaneously: first, to adjust the grounding pressure of the roller brush 203 in the sweeping assembly 2 to obtain the best sweeping effect; second, to lift the working parts as a whole during non-operational movement to enhance the equipment's passability.

[0038] (2) Second stage: Cleaning, collection and lifting operations After the equipment attitude adjustment is completed, the operator issues the operation command through control box 402: 1. Movement and Sweeping: The control box 402 commands the two first drive motors 302 (usually DC motors) of the left and right walking tracks 301 to provide forward power. The two motors can operate at different speeds, enabling the equipment to move flexibly forward, backward, and turn within the trench. Simultaneously, the third drive motor 204 starts, driving the roller brush 203 of the sweeping assembly 2 to rotate at high speed through a gear transmission mechanism, gear shaft, and chain 211 transmission mechanism. The roller brush 203 sweeps up the mud, fallen leaves, gravel, and other debris deposited at the bottom of the trench, moving forward and to the sides.

[0039] 2. Waste Gathering and Conveying: Under the rotational force of the roller brush 203 and the constraint of the casing 202, the swept-up waste is guided to the discharge port 213 behind the casing 202. The discharge port 213 is designed as a "gathering plate" structure with a gradually narrowing cross-section, which can effectively concentrate and gather the scattered waste to form a directional waste flow. This waste flow is accurately delivered through the discharge port 213 to the inlet at the bottom of the conveying shell 102 of the waste lifting assembly 1.

[0040] 3. Waste Lifting: Simultaneously with the start of the sweeping operation, the second drive motor 121 of the waste lifting assembly 1 starts, driving the drive shaft 103 of the conveyor belt 101 to rotate. The conveyor belt 101 employs a special design with sidewalls and operates continuously. Waste falling onto the conveyor belt 101 from the feed inlet is supported by the sidewalls and scrapers of the conveyor belt 101. During the lifting process, the leak-proof bottom plate 105, fixed to the bottom of the conveyor housing 102, tightly holds the bottom of the conveyor belt 101 to prevent waste leakage from the bottom. The conveyor belt 101 stably and continuously transports the waste diagonally upwards until it reaches the unloading end at the top.

[0041] (3) Third stage: Garbage unloading and cleanup The garbage, lifted to the top, is thrown out from the discharge end of the conveyor belt 101 under gravity and falls into the discharge hopper 502 of the discharge assembly 5 located directly below it. After collecting the garbage, the discharge hopper 502 guides it to the outlet. A discharge guide chute 503 is hinged below the outlet, guiding the garbage to be concentrated and orderly dumped onto the bank slope of the drainage ditch or into a collection vehicle. The discharge guide chute 503 can be flipped via a pin 504 to adjust the discharge direction and position. This completes a full work cycle from "sweeping → collecting → lifting → unloading". The equipment continues to move within the ditch, and this cycle continues continuously, achieving continuous and efficient cleaning of the drainage ditch.

[0042] After the operation is completed, the equipment can be driven to a location that is convenient for hoisting or transportation. The quick-release design allows it to be quickly disassembled into five modules, making it easy to transfer to the next work site or store in a warehouse.
