Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a bridge cable-stayed bridge cleaning device for bridge construction. Background Technology

[0002] Bridge stay cables are critical components in bridge structures that bear enormous tensile forces. They are typically exposed to the outdoor environment and are therefore affected by various natural factors such as air pollution, wind erosion, and rain. Over time, dust, stains, and other contaminants can accumulate on the surface of the stay cables. These deposits not only affect the appearance of the stay cables but, more importantly, can reduce their durability and even affect their mechanical properties. Therefore, bridge stay cables require regular cleaning.

[0003] The utility model patent with publication number CN210907087U discloses a bridge cable cleaning device for bridge construction. The device has two semi-circular shells that can be directly fastened to the cable and tightened, realizing machine cleaning of the cable, saving cleaning time, and also cleaning the cable from all angles.

[0004] However, in practical applications, the fixed installation positions of the power wheel and brush of the device limit its ability to clean only cables of a specific diameter, resulting in a narrow range of applications. Secondly, the sponge cleaning block is located at the bottom, causing the wastewater from cleaning the cables to flow through the sponge cleaning block, which can cause dirt to re-adhere to the cables, reducing the cleaning effect. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing cable-stayed bridge cleaning equipment can only clean cables of a specific diameter, resulting in a narrow range of applications; and the cleaned-off dirt may re-adhere to the cables, leading to poor cleaning results.

[0006] To solve the above problems, the technical solution of this utility model is: a bridge cable-stayed bridge cleaning device for bridge construction, comprising a cylinder, with driving components installed at both ends of the cylinder and cleaning components installed inside, the cylinder being formed by connecting two semi-circular shells;

[0007] The drive assembly includes multiple mounting frames, each with a roller installed inside and an adjusting rod fixed to its top. A motor for driving the roller to rotate is installed on the outside of one of the mounting frames. Multiple fixing rods are fixed to the ends of the housing, and a positioning cylinder sleeved on the outside of the adjusting rod is fixed to the end of each fixing rod.

[0008] The cleaning assembly includes a spray pipe installed at one end of a cylinder, with multiple nozzles on the spray pipe. An inner cylinder is rotatably installed inside the cylinder, and multiple cleaning brushes are installed inside the inner cylinder. An external toothed ring is installed on the outer side of the inner cylinder. The cleaning brushes are installed on the inner wall of the inner cylinder via a telescopic rod. A second motor is installed on the outer side of the cylinder, and a through groove is opened on the surface of the cylinder. A gear that meshes with the external toothed ring is installed on the output shaft of the second motor. The inner cylinder is formed by the joining of two arc-shaped plates of the same size, and the external toothed ring is formed by the joining of two arc-shaped racks of the same size.

[0009] Furthermore, connecting strips are fixed to both ends of the housing, and multiple through holes are provided on the connecting strips. The connecting strips on the two housings are connected and fixed by bolts and nuts.

[0010] Furthermore, the mounting frames are provided in six units and are arranged in a circular array about the cylinder.

[0011] Furthermore, threaded holes are symmetrically opened on both sides of the positioning cylinder, and set bolts are installed in the threaded holes, with the ends of the set bolts abutting against the adjusting rod.

[0012] Furthermore, two nozzles are installed at the end of the cylinder. The nozzles are arc-shaped, and the water inlet ends of the two nozzles extend to the outside of the shells after passing through the two shells respectively.

[0013] Furthermore, annular rails for defining the position of the inner cylinder are installed at both ends of the inner cylinder inside the cylinder. The side of the annular rails is provided with limiting grooves that are adapted to the inner cylinder. The annular rails are formed by the joining of two arc-shaped rails of the same size.

[0014] Furthermore, the cleaning brush is provided in four parts, and is arranged in a circular array about the inner cylinder, with two cleaning brushes installed on each arc plate.

[0015] The advantages of this invention compared to existing technologies are as follows: the position of the rollers is adjustable, and the cleaning brush can come into contact with the surface of cables of different diameters through the setting of the telescopic rod, making it widely applicable; when the equipment moves up and down along the cable, it can respectively brush and rinse the surface of the cable, improving the cleaning effect of the cable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, a bridge cable-stayed bridge cleaning device for bridge construction includes a cylinder with drive components installed at both ends and a cleaning component installed inside. The cylinder is formed by connecting two semi-circular shells 1. Connecting strips 2 are fixed to both ends of the shells 1. Multiple through holes are provided on the connecting strips 2. The connecting strips 2 on the two shells 1 are connected and fixed by bolts and nuts.

[0023] The cylinder is formed by connecting two semi-circular shells 1, which facilitates the installation of the cylinder on the outside of the bridge stay cable to achieve cleaning of the stay cable.

[0024] The drive assembly includes six mounting frames 3 arranged in a circular array about the cylinder. Rollers 4 are installed inside each mounting frame 3, and an adjusting rod 5 is fixed to the top. A motor 6 for driving the rollers 4 to rotate is installed on the outside of one of the mounting frames 3. Multiple fixing rods 7 are fixed to the end of the housing 1. A positioning cylinder 8 is fixed to the end of each fixing rod 7 and sleeved on the outside of the adjusting rod 5. Threaded holes are symmetrically opened on both sides of the positioning cylinder 8. Set bolts are installed in the threaded holes, and the ends of the set bolts abut against the adjusting rod 5.

[0025] The adjusting rod 5 can slide along the positioning cylinder 8, which allows the roller 4 to press against the surface of the cable. When the motor 6 drives the roller 4 to rotate, the equipment can move along the cable. By setting drive components at both ends of the cylinder, the stability between the cylinder and the cable is ensured while providing dual drive, so that the equipment has sufficient power to move.

[0026] like Figure 1 , Figure 3 and Figure 4As shown, the cleaning assembly includes nozzles 9 installed at both ends of a cylinder, with multiple nozzles 10 on the nozzles 9. An inner cylinder is rotatably installed inside the cylinder, and multiple cleaning brushes 12 are installed inside the inner cylinder. An external toothed ring is installed on the outer side. The cleaning brushes 12 are installed on the inner wall of the inner cylinder via a telescopic rod 13. A second motor 14 is installed on the outer side of the cylinder, and a through groove is opened on the surface of the cylinder. A gear 15 that meshes with the external toothed ring is installed on the output shaft of the second motor 14. The inner cylinder is formed by joining two arc-shaped plates 16 of the same size, and the external toothed ring is formed by joining two arc-shaped racks 17 of the same size.

[0027] The water inlet ends of the two nozzles 9 are connected to the water supply pipe via flexible hoses. To ensure water pressure, a water pump is generally used for water supply. When installing the cylinder, the end of the nozzle 9 is positioned at the top. As the cylinder rises along the cable, the nozzle 10 sprays water onto the surface of the cable. The motor 14 drives the gear 15 to rotate, and the gear 15 drives the inner cylinder to rotate through the outer gear ring. The inner cylinder drives the cleaning brush 12 to rotate, thus cleaning the cable. Spraying water can prevent dust from being generated during the cleaning process. When the equipment moves to the top of the cable, it begins to move downwards. At this time, the water sprayed from the nozzle 10 rinses the surface of the cable. The extension rod 13 ensures that the cleaning brush 12 can contact the surface of the cable when cleaning cables of different diameters, thus improving the applicability.

[0028] In practical use, this device is powered by an external power source and connected to an external PLC controller. The PLC controller controls the starting, stopping, forward and reverse rotation of motor 6 and motor 14. The two housings 1 are installed on the outside of the cable stay, forming a cylinder fitted on the outside of the cable stay. The height of the roller 4 is adjusted so that the roller 4 is pressed against the surface of the cable stay. The forward rotation of motor 6 causes the device to move upward along the cable stay. The nozzle 10 sprays water onto the surface of the cable stay. Motor 14 drives the cleaning brush 12 to rotate to clean the cable stay. When the device moves to the top of the cable stay, it begins to move downward. At this time, the water sprayed from the nozzle 10 rinses the surface of the cable stay.

[0029] The parts not disclosed in this utility model are all existing technologies, such as the PLC controller and its wiring method with motor 6 and motor 14. Their specific structure and working principle will not be described in detail.
