Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand suction bridge track cleaning technology, specifically to an automatic cleaning device for truss tracks. Background Technology
[0002] Sand suction bridge equipment is used in the field of wastewater treatment. The sand suction bridge equipment includes a track and adopts a truss structure. Since the equipment is set outdoors, snow, ice, sand and other foreign objects will accumulate on the track surface. The accumulation of foreign objects will reduce the friction coefficient of the wheel-rail contact surface, causing the vehicle to slip, increase the braking distance, and also create a risk of short circuit in the track circuit.
[0003] Manual cleaning is time-consuming, laborious, and poses safety hazards, delaying normal production.
[0004] Therefore, there is an urgent need for a track cleaning device that can easily remove foreign objects from the track. Summary of the Invention
[0005] To address the problems associated with manual cleaning of existing sand-absorbing bridge tracks, this utility model proposes an automatic truss track cleaning device. Based on the movement of a trolley along with a truss vehicle, it is equipped with a combined flexible and rigid scraper blowing mechanism to clean sand, gravel, snow, and ice.
[0006] To achieve the above objectives, this utility model proposes an automatic cleaning device for truss tracks, including a trolley and a truss vehicle. The truss vehicle pulls the trolley to move on the track. The trolley includes a housing, a first cleaning mechanism, a second cleaning mechanism, and a blowing mechanism. The first cleaning mechanism includes a flexible scraper. One side of the flexible scraper is detachably connected to the second cleaning mechanism, and the other side is in contact with the track surface. The second cleaning mechanism includes a rigid scraper, which is long and narrow. A lifting mechanism is provided between the rigid scraper and the housing. The rigid scraper is fixed to the housing through the lifting mechanism. An anti-collision mechanism is provided on the housing and contacts the rigid scraper. The box has a hollow square structure, and the side of the box is hinged with a door. The blowing mechanism is installed inside the box, and a blowing duct is installed at the bottom of the box corresponding to the blowing mechanism. A track wheel is installed behind the blower duct. The track wheel is an I-beam wheel with a rotating shaft. The track wheel and the rotating shaft are fixed together. The rotating shaft is rotatably connected to the housing through a bearing.
[0007] Furthermore, the flexible scraper is a U-shaped structure made of nylon material, with a round hole at the top. A bolt is provided between the round hole and the rigid scraper, and the flexible scraper is connected to the rigid scraper by the bolt.
[0008] The flexible scraper is made of nylon, which combines good flexibility and wear resistance. The flexibility ensures that the scraper fits tightly to the track surface, improving the removal of surface dust, while the wear resistance extends the scraper's service life and reduces the hassle of frequent replacements. The concave structure is adapted to the shape of the track, allowing for a wrap-around cleaning of the sides and top of the track, avoiding cleaning dead corners and further improving the overall cleaning effect.
[0009] The round hole at the top of the flexible scraper is connected to the rigid scraper by bolts, making it easy to replace the flexible scraper.
[0010] Furthermore, the rigid scraper is a long strip structure made of steel; The lifting mechanism includes a hand-cranked lead screw, the fixed seat of which is fixed to the housing, and the nut of which is fixed to the side of the rigid scraper.
[0011] Rigid scrapers are mainly used for cleaning snow and ice. They are rigid and positioned in front of flexible scrapers to clean snow and ice. The height of the rigid scraper from the track surface can be adjusted by hand cranking a screw, which enhances the scraping effect.
[0012] Furthermore, the two anti-collision mechanisms include a buffer plate and a fixing plate. The fixing plate is U-shaped, and its two ends are fixed to the box body. A rigid scraper is provided in the recess of the fixing plate, and the side of the fixing plate without a recess is fixed to the buffer plate.
[0013] The anti-collision mechanism is used to protect the lifting mechanism and the rigid scraper.
[0014] Furthermore, the purging mechanism includes a blower, which is fixed inside the housing, and the blower's outlet is connected to the blowing pipe via a flexible pipe connection. The air blowing duct is set at an angle, and the outlet of the air blowing duct extends out of the box and opens downward.
[0015] The blower has strong airflow, generating enough to blow away residual debris from the track. It also provides good assistance in snow and ice removal. The angled design allows the airflow to blow obliquely along the track surface, preventing debris from splashing to other areas due to the vertical downward airflow. The downward opening ensures that the airflow acts directly on the track surface, improving the debris removal effect and preventing residual impurities from re-adhering to the track.
[0016] The beneficial effects of this utility model through the above technical solution are as follows: This utility model includes a trolley that moves with a gantry car and automatically cleans the track surface during movement. It integrates a first cleaning mechanism (flexible scraper), a second cleaning mechanism (rigid scraper), and a blowing mechanism to form a scraping, sweeping, and blowing cleaning system. The flexible scraper conforms to the track surface to remove surface dust and fine impurities, avoiding scratches; the rigid scraper can handle ice and snow, and its height can be adjusted according to the thickness of the ice and snow using a lifting mechanism to ensure thorough cleaning; the blowing mechanism blows away residual ice and snow removed by the scraper through a bottom air duct. The synergistic effect of these three mechanisms significantly improves track cleaning efficiency.
[0017] The track wheels adopt an I-beam design, which is highly adaptable to the track. With the rotational connection of the shaft and bearing, the frictional resistance between the trolley and the track can be reduced when the trolley moves, ensuring that the trolley travels smoothly along the track. At the same time, the anti-collision mechanism contacts the rigid scraper, which can play a buffering role when the rigid scraper is subjected to accidental impact, avoiding deformation or damage to the scraper and extending the service life of the equipment.

Detailed Implementation
[0020] Example 1 like Figure 1-3 As shown, an automatic cleaning device for truss tracks includes a trolley and a truss vehicle. The truss vehicle pulls the trolley to move on the track. The trolley includes a housing 1, a first cleaning mechanism, a second cleaning mechanism, and a blowing mechanism. The first cleaning mechanism includes a flexible scraper 2. One side of the flexible scraper 2 is detachably connected to the second cleaning mechanism, and the other side is in contact with the track surface. The second cleaning mechanism includes a rigid scraper 3, which has a long strip structure. A lifting mechanism is provided between the rigid scraper 3 and the housing 1. The rigid scraper 3 is fixed to the housing 1 through the lifting mechanism. An anti-collision mechanism is provided on the housing 1, and the anti-collision mechanism is in contact with the rigid scraper 3. The box 1 has a hollow square structure. The side of the box 1 is hinged with a door. The blowing mechanism is installed inside the box 1. Corresponding to the blowing mechanism, a blowing pipe 4 is installed at the bottom of the box 1. A track wheel 5 is provided behind the air blowing duct 4. The track wheel 5 is an I-beam wheel. The track wheel 5 is provided with a rotating shaft 6. The track wheel 5 is fixed to the rotating shaft 6. The rotating shaft 6 is rotatably connected to the housing 1 through a bearing.
[0021] The flexible scraper 2 is a U-shaped structure made of nylon material. A round hole is opened at the top of the flexible scraper 2. A bolt is provided between the round hole and the rigid scraper 3. The flexible scraper 2 is connected to the rigid scraper 3 by the bolt.
[0022] The rigid scraper 3 is a long strip structure made of steel; The lifting mechanism includes a hand crank screw 7, the fixed seat of the hand crank screw 7 is fixed to the housing 1, and the nut of the hand crank screw 7 is fixed to the side of the rigid scraper 3.
[0023] The two anti-collision mechanisms include a buffer plate 8 and a fixed plate 9. The fixed plate 9 is U-shaped. The two ends of the fixed plate 9 are fixed to the box body 1. A rigid scraper 3 is provided in the recess of the fixed plate 9. The side of the fixed plate 9 without the recess is fixed to the buffer plate 8.
[0024] The purging mechanism includes a blower 10, which is fixed inside the housing 1, and the air outlet of the blower 10 is connected to the blowing pipe 4 via a flexible pipe connection. The air blowing pipe 4 is set at an angle, and the outlet of the air blowing pipe 4 extends out of the box 1 with the opening facing downward.
[0025] In this embodiment, the blower 10 uses a magnetic levitation motor with a power of 1.5kW and a wind pressure ≥8kPa. The flexible scraper 2 has a Shore hardness of 75±5 and a wear rate of <0.1mm / 1000km. The blower 10 is connected to the power supply inside the gantry vehicle via a circuit breaker, and the blower needs to be switched on and off according to the environmental testing requirements.
[0026] The gantry car is connected to the trolley via a coupler. During operation, the gantry car pulls the trolley to move at a constant speed along the track. During the movement of the trolley, the flexible scraper 2 of the first cleaning mechanism comes into contact with the track surface first. The flexible scraper 2 is a U-shaped structure made of nylon with a Shore hardness of 75±5. It has both flexibility and wear resistance, and can closely fit the top and sides of the track to initially scrape away light impurities such as floating dust and fine sand particles from the track surface. This prevents sand particles from scratching the track surface as the trolley moves. At the same time, the U-shaped structure can eliminate cleaning dead corners and ensure that sand and dust on all contact surfaces of the track are scraped off. In icy and snowy weather, the height of the rigid scraper 3 is adjusted by hand-cranking the screw 7. The rigid scraper 3 is brought close to the track. The circuit breaker is then turned on to start the blower 10. A strong airflow is directed obliquely towards the track surface through the air duct 4. This serves two purposes: firstly, it blows away any remaining ice and snow particles from the track after the rigid scraper 3 and flexible scraper 2 have been removed, preventing them from accumulating on the track surface and refreezing; secondly, the airflow accelerates the evaporation of moisture from the track surface, preventing water accumulation due to melting residual ice and snow, thus preventing the water from refreezing in low temperatures. This ensures the track surface is dry and free of ice and snow residue, guaranteeing the safety of subsequent equipment operating along the track. The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
