Description

Technical Field

[0001] This utility model relates to the field of oil spraying device technology, specifically an oil spraying device for automatic oil spraying inside the compartment of an asphalt transport vehicle. Background Technology

[0002] With the continuous expansion of highway construction and the increasing technical requirements, traditional asphalt transportation operations have exposed numerous problems. During the use of asphalt truck beds, the asphalt mixture often adheres firmly to the inner walls, making manual cleaning extremely difficult. This not only consumes a significant amount of manpower and valuable time resources, but also hinders construction progress. To address this, manual spraying of vegetable oil into the asphalt truck beds has several drawbacks. Due to the limitations of manual operation, it is difficult to ensure the even distribution of the oil within the truck bed, potentially resulting in overspray in some areas and underspray in others. Manual spraying is relatively slow, especially when dealing with a large number of truck beds, consuming considerable time and manpower. It is also difficult to accurately control the dosage of vegetable oil used, potentially leading to waste or insufficient application, affecting the overall effect. Prolonged manual spraying work can cause worker fatigue, increasing labor intensity and impacting work quality and efficiency. Workers may be exposed to harmful volatile substances during spraying, posing a potential threat to their health. Improper operation may also lead to dripping and splashing of vegetable oil, causing environmental pollution. Manual operation is inefficient, increasing construction time and costs, and making it difficult to guarantee optimal spraying results. Furthermore, the insufficient uniformity of manually sprayed vegetable oil makes it difficult to thoroughly clean the asphalt mixture, leading to a continuous reduction in the effective loading space of truck beds, decreased transportation efficiency, and a significant increase in transportation costs. Simultaneously, the mixing of residual asphalt mixture with new asphalt can damage the original performance indicators of the asphalt, having a serious negative impact on the quality of highway pavements, such as reducing pavement smoothness, skid resistance, and durability.

Detailed Implementation

[0017] The technical solution of one embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] Please see Figure 1-2 :

[0019] An automatic oil spraying device for the interior of an asphalt transport vehicle includes a movable frame, an oil spraying carriage 131, an oil spraying rotation mechanism, an oil spraying lifting mechanism, an oil spraying pump 112, and a spray pipe 3. The movable frame includes a left frame 11 and a right frame 12 spaced apart, and a connecting frame 13 connecting the tops of the left frame 11 and the right frame 12. The lower part of the movable frame is equipped with the oil spraying pump 112 and a control cabinet 111. The oil spraying carriage 131 is movably mounted on the connecting frame 13. The bottom of the oil spraying carriage 131... The device is equipped with an oil spraying rotation mechanism, and an oil spraying lifting mechanism at the bottom of the oil spraying rotation mechanism. The oil spraying lifting mechanism is equipped with a lifting plate 21, and a spray pipe 3 is provided on the lifting plate 21. The spray pipe 3 is equipped with several nozzles. The spray pipe 3 is connected to the oil spraying pump 112 through an oil spraying pipe. The oil spraying rotation mechanism can be realized by a motor driving a turntable bearing. The spray pipe 3 of the oil spraying device is lowered into the asphalt transport vehicle compartment through the oil spraying lifting mechanism, and oil is sprayed on various parts of the inner surface of the asphalt transport vehicle compartment through the oil spraying trolley 131 and the oil spraying rotation mechanism.

[0020] This spraying device is designed to be automated. By moving the spraying carriage 131 on the connecting frame 13 and rotating the spraying mechanism, it can achieve comprehensive and rapid spraying of the inner surface of the asphalt transport truck bed. Compared with traditional manual spraying, this automated spraying method can significantly improve spraying efficiency and save time and labor costs.

[0021] The fuel injection device's fuel injection lifting mechanism can precisely control the fuel injection height, ensuring that the distance between the nozzle and the inner surface of the vehicle is appropriate, thereby achieving a uniform fuel injection effect.

[0022] The design of the movable frame in the spraying device allows the spraying device to be easily moved to different positions in the asphalt transport vehicle compartment for operation.

[0023] The lower part of the movable frame is also equipped with an air compressor 121. A three-way connector is connected to the oil injection pipe. The output end of the three-way connector is connected to the oil injection pipe, and the two input ends of the three-way connector are connected to the oil injection pump 112 and the air compressor 121 respectively through connecting pipes. Control solenoid valves are respectively installed on the connecting pipes of the oil injection pump 112 and the air compressor 121. After the oil injection is completed, some oil residue often remains inside the nozzle. If this residual oil is not removed in time, it may drip during subsequent operations, causing pollution of the working environment or waste of oil. By setting up the air compressor 121, after the oil injection operation is completed, the nozzle will switch to the jet mode through the solenoid valve. At this time, high-pressure compressed air will quickly pass through the nozzle, generating a strong airflow. This airflow can thoroughly blow away the inside of the nozzle, removing all residual oil adhering to the nozzle wall or dead corners. In this way, the jet blowing by the compressed air provided by the air compressor 121 can ensure that the inside of the nozzle is clean and free of residue, thereby effectively preventing oil dripping from the nozzle.

[0024] The nozzle 3 is L-shaped, and the lifting plate 21 is provided with through holes 2211 corresponding to the nozzles on the vertical tube of the nozzle 3. The nozzles on the horizontal tube of the nozzle 3 face downwards. Since the carriage is square, this design makes the nozzle 3 L-shaped to facilitate simultaneous oil spraying on the sides and bottom of the carriage, thereby improving oil spraying efficiency.

[0025] A lifting frame 22 is provided on the lifting plate 21. The lifting frame 22 has an opening, and the lifting plate 21 covers the opening. The lifting frame 22 includes a nozzle side plate 221, which has several through holes 2211. The vertical tube of the spray pipe 3 is located inside the lifting frame 22. The nozzle side plate 221 has through holes 2211 corresponding to the nozzles on the vertical tube of the spray pipe 3. The horizontal tube of the spray pipe 3 extends out of the bottom of the lifting frame 22. The lifting frame 22 can accommodate the oil pipes, allowing them to be stored in an orderly manner, thereby maintaining a clean and safe working environment.

[0026] The fuel injection lifting mechanism includes a lifting cylinder, a fixed plate 24, and a guide rod 221. One end of the fixed plate 24 is connected to the turntable, one side of the lifting cylinder is connected to the fixed plate 24, and the other side of the lifting cylinder is connected to the lifting plate 21. One end of the guide rod 221 is connected to the turntable, and the other end is connected to the lifting frame 22. This ensures that the lifting cylinder remains stable during operation and will not easily shake due to rotation.

[0027] The lifting cylinder is a hydraulic cylinder 2. The lower inner part of the left frame 11 is equipped with a control cabinet 111, an oil injection pump 112 and an oil tank 113. The oil tank 113 is equipped with a liquid level sensor and electric heating to maintain the oil temperature. The lower inner part of the right frame 12 is equipped with an air compressor 121 and a hydraulic pump station 122.

[0028] The oil injection device also includes two tracks 4 spaced apart. The bottom of the left frame 11 and the right frame 12 are provided with traveling wheels 100. The traveling wheels 100 are rolled on the tracks 4. The traveling wheels 100 are driven by a motor reducer through a chain to move back and forth on the tracks 4. The moving speed can be adjusted by a frequency converter.

[0029] The track 4 has stops 41 at both ends, which are fixed to the ground, and the track 4 is embedded in the stops 41. The stops 41 are fixed to both ends of the track 4, which effectively prevents the fuel injection device from exceeding the predetermined range during movement, thereby avoiding possible collisions or overturning accidents. This safety design enhances the reliability of the fuel injection device during use.

[0030] The connecting frame 13 is equipped with two guide rails 132 spaced apart. The fuel injection carriage 131 is equipped with an upper wheel 1311 and a lower wheel 1312, which slide on the upper and lower bottom surfaces of the guide rails 132 respectively. The left and right movement of the fuel injection carriage 131 is achieved by a synchronous belt driven by a motor reducer of the moving drive mechanism 130. Limit sensors are installed on both sides to limit the position. The grooves on the guide rails 132 provide a stable guide rail for the fuel injection carriage 131. The arrangement of the upper wheel 1311 and the lower wheel 1312 ensures the stability of the fuel injection carriage 131 during movement. This design effectively reduces vibration and shaking during movement and improves the accuracy and stability of the fuel injection operation.

[0031] When in use, the asphalt truck drives into the middle position below the spraying device and the spraying device is activated. The L-shaped nozzle sprays oil into the truck bed through horizontal, vertical, and rotational movements, as well as the movement of the moving frame.

[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
