Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example: A tunnel synchronous lining invert arch trestle boom placement device includes a rotary reducer (1), which is fixedly installed on the trestle and serves as the basic rotating component of the entire device. It provides power and support for the rotation of the folding telescopic boom (2), enabling the boom to rotate within a certain range and thus adjust the placement direction. The rotary reducer (1) is rotatably connected to the folding telescopic boom (2). The rotary reducer (1) is used for extending and folding, adjusting the placement distance and coverage area, and delivering concrete to different positions on the tunnel invert arch. A folding pipeline system (3) is installed on one side of the folding telescopic boom (2), and the folding... The stacked pipeline system (3) passes through the interior of the rotary reducer (1). The folded pipeline system (3) is connected to an external conveying pump, which can transport concrete and provide a material transmission channel for the construction of the invert arch. A remote control electrical control device (4) is fixedly connected to one side of the rotary reducer (1) to receive and process control signals and control the operation of each component of the entire device (such as the rotary reducer, telescopic cylinder, etc.). Telescopic cylinders (5) are installed between the two rotating sections of the folded telescopic boom (2) and between the folded telescopic boom (2) and the rotary reducer (1). The telescopic cylinders (5) provide power for the unfolding, folding and angle adjustment of the folded telescopic boom.

[0019] The folding pipeline system (3) includes several metal pipes (31) of different lengths. The metal pipes (31) serve as the main channels for concrete transportation. The different lengths are adapted to the different extension and folding states of the boom. Compared with traditional hose transportation, metal has high strength and good pressure resistance. It can withstand the pressure and impact during concrete transportation and is not easily damaged or deformed, ensuring the smoothness of concrete transportation. The metal pipes (31) are installed inside the rotary reducer (1) and on one side of the folding telescopic boom (2). Except for the metal pipe (31) at the end used for material discharge, which is connected to a bend (32) at one end, all other metal pipes (31) are connected to bends (32) at both ends. The bends (32) can change the direction of concrete transportation and adapt to the folding and extension forms of the boom, so that the pipeline system can flexibly deform with the boom, ensuring the sealing and continuity of the pipeline system. Two adjacent sections of metal pipes (31) are connected by two bends (32).

[0020] The metal pipe (31) and the bend (32) are both tightly connected by flange clamps (33). The flange clamps (33) serve as fastening connection components for the pipeline (metal pipe and bend, bend and bend), ensuring the sealing and stability of the pipeline connection and ensuring the reliability of the pipeline system when conveying concrete under high pressure.

[0021] The rotary reducer (1) includes a base (11), a reducer (12), and a rotary table (13). The base (11) fixes the entire rotary reducer on the trestle and provides stable support. The reducer (12) can reduce the speed and increase the torque to provide suitable power output for the rotation of the rotary table. The rotary table (13) can realize the rotation function, drive the folding telescopic arm and other components to rotate, and adjust the circumferential position of the fabric. The base (11) is fixedly installed on the trestle, and the rotary table (13) is rotatably installed on the upper end of the base (11). The reducer (12) is installed between the base (11) and the rotary table (13). One side of the rotary table (13) is fixedly connected to the remote control electric control device (4).

[0022] The folding telescopic boom (2) includes a first-level robotic arm (21), a second-level robotic arm (22), and a third-level robotic arm (23) that are rotatably connected in sequence. The first-level robotic arm (21) serves as the basic boom segment of the folding telescopic boom and is connected to the turntable, bearing the load of subsequent boom segments and transmitting power. The second-level robotic arm (22) extends the extension length of the boom and, in conjunction with the first-level and third-level robotic arms, adjusts the fabric range to further extend the farthest position of the fabric. The third-level robotic arm (23) finely adjusts the end position of the fabric to improve the accuracy of the fabric application. The first-level robotic arm (21) is rotatably connected to the turntable (13). Telescopic cylinders (5) of different specifications are installed between the first-level robotic arm (21) and the second-level robotic arm (22), between the second-level robotic arm (22) and the third-level robotic arm (23), and between the first-level robotic arm (21) and the turntable (13). Different specifications are adapted to the action requirements of different connection parts, ensuring that the actions of each part are coordinated and powerful, and realizing the complex folding and extension actions of the boom.

[0023] The remote-controlled electrical control device (4) includes an electrical control box (41), a hydraulic oil tank assembly (42), a motor assembly (43), a filter (44), and a four-way multi-port valve (45). The electrical control box (41) houses and protects the internal electrical components, providing an installation and operating environment for the control of each component. The hydraulic oil tank assembly (42) integrates the oil tank body, the oil circuit integration module, the level and temperature detection unit, etc. It not only stores hydraulic oil but also monitors the hydraulic oil status (level, temperature) in real time. Through the oil circuit integration module, it optimizes the hydraulic oil distribution, providing a stable and suitable working medium for hydraulic actuators such as telescopic cylinders. It also has preliminary oil purification and buffer pressure shock functions to ensure the reliable operation of the hydraulic system. The motor assembly integrates the motor assembly body, the motor assembly controller, the overload protection module, etc. In addition to providing power to the hydraulic pump, it can precisely control the speed and torque of the motor assembly to adapt to different construction conditions; the overload protection module automatically cuts off power when the load is abnormal to avoid equipment damage and improve the stability and reliability of the hydraulic system's power output; the filter (44) is used to filter impurities in the hydraulic oil to ensure the cleanliness of the hydraulic oil, protect hydraulic system components (such as cylinders, hydraulic pumps, etc.), and extend the service life of the components; the four-way valve (45) can control the flow direction and pressure of the hydraulic oil to realize the separate control of multiple telescopic cylinders and other hydraulic components. The electrical control box (41) is fixedly connected to the rotary table (13), and the hydraulic oil tank assembly (42), motor assembly (43), filter (44) and four-way valve (45) are all installed in the electrical control box (41).

[0024] A radiator (6) is installed inside the electrical control box (41), and the radiator (6) is located on one side of the motor assembly (43). The radiator (6) can dissipate the heat generated by the generator assembly and other components, reduce the temperature inside the electrical control box, ensure that the motor assembly and other equipment operate at a suitable temperature, avoid performance degradation or failure due to overheating, and improve the stability and reliability of the device operation.

[0025] The top of the electrical control box (41) and the hydraulic oil tank assembly (42) is fixedly connected with a lifting eye screw (7). The lifting eye screw (7) facilitates the transfer, installation and debugging of the device during construction.

[0026] Work process: S1. When concrete placement is required during the synchronous lining of the tunnel arch, the operator should send a control signal via remote control from a safe position away from the trestle. S2. After receiving the signal, the remote control device (4) starts the motor assembly (43), and the hydraulic oil is drawn from the hydraulic oil tank assembly (42), filtered by the filter (44), and distributed to each telescopic cylinder (5) through the four-way valve (45). S3. The telescopic cylinder (5) performs telescopic movements according to the requirements of the control signal, thereby driving the folding telescopic boom (2) to perform unfolding, folding, and rotating movements, and adjusting to the appropriate fabric position and angle. S4. Concrete is pumped into the folded pipeline system (3) and transported from the end outlet to the construction site of the tunnel invert via a pipeline consisting of a metal pipe (31) and a bend (32). In this embodiment, a folding telescopic boom and a folding pipeline system are installed, which enables long-distance material placement without requiring concrete mixer trucks to be on the bridge. This avoids obstructing the construction passage, ensures the normal transportation of other construction equipment and materials, and effectively speeds up the construction progress. At the same time, it reduces the load of heavy mixer trucks on the trestle bridge, lowers the risk of damage to the trestle bridge structure, and provides a safer working environment for construction personnel, effectively eliminating safety hazards.
