[0009] Preferably, one end of the robot arm away from the mobile chassis is fixedly connected to a laser locator, and one side of the mobile chassis away from the conveying mechanism is fixedly connected to a position sensor.

[0010] Preferably, one end of the tension spring away from the mounting seat is fixedly connected to a side of the limiting plate close to the mounting seat, and a side of the sliding column away from the mounting seat passes through a side of the fixing tube away from the mounting seat.

[0013] Preferably, a non-slip pad is provided on one side of the clamping plate away from the rotating clamping arm, and the bottom of the push-pull arm is rotatably connected to the outer side of the rotating clamping arm.

[0014] Preferably, the output end of the motor is connected to one of the rotating shafts via a belt, and the lifting frame is arranged inside the storage box.

[0015] Working principle: First, place the pipeline inside the storage box. When releasing the pipeline, start the hydraulic rod. The output end of the hydraulic rod extends to drive the lifting frame to rise. At this time, the pipeline inside the storage box is lifted out of the storage box. At the same time, start the motor. After the output end of the motor rotates, it drives one of the rotating shafts to rotate through the belt. The rotating shaft drives the chain to rotate through the gear plate, thereby driving the hook pipe assembly to rotate. The hook pipe assembly is used to hook the pipeline and transmit it to the top of the chain close to the side of the mechanical arm. At this time, the mechanical arm can be used to drive the elastic clamping mechanism to clamp and release the pipeline.

[0016] When the pipeline is thicker, the hook is squeezed by the pipeline to extend toward the moving chassis, and drives the sliding column to move out of the fixed cylinder, thereby driving the limit plate to slide inside the fixed cylinder, and using the limit plate to limit to prevent the sliding column from moving out of the fixed cylinder, and at the same time, the limit plate can be used to stretch the tension spring, when the pipeline moves out of the hook, the limit plate is pulled to move toward the mounting seat under the action of the tension spring, and drives the sliding column and the hook to move toward the mounting seat, so that the hook can be reset;

[0017] When the elastic clamping mechanism clamps the pipeline, the hydraulic cylinder is first started. When the output end of the hydraulic cylinder extends, it drives the base frame to move downward. When the base frame moves downward, the unchanged length of the push-pull arm can be used to pull the bottom of the rotating clamping arm outward to expand, and then the two connected hollow columns, the base plate and the clamping plate can be driven to separate. When the pipeline is reached, the hydraulic cylinder is started again, and the output end of the hydraulic cylinder contracts. After the hydraulic cylinder contracts, it can drive the base frame to move upward. After the base frame moves upward, the unchanged length of the push-pull arm is used to push the rotating clamping arm. The bottom of the rotating clamping arm moves toward the middle, and then the connected hollow column, the base plate and the clamping plate can be driven to move toward the middle, and then the pipeline can be clamped. When clamping the pipeline, the installation cylinder moves toward the direction of the clamping plate, and then the spring can be compressed, thereby realizing elastic clamping and avoiding damage to the pipeline by rigid clamping.

[0018] The present invention provides an automatic pipeline laying device for communication pipeline construction. It has the following beneficial effects:

[0019] 1. When the present invention clamps the pipeline through the clamping plate, the elasticity of the return spring is used to play a certain buffering role after the pipeline is clamped, so that the pipeline will not be twisted or damaged due to hard clamping. Therefore, the pipeline is protected during clamping, and economic losses can be avoided during deployment.

[0020] 2. The present invention can drive the chain to rotate through the belt through the rotation of the output end of the motor, thereby driving the hook pipe assembly to automatically hook and transport the pipeline, and can use the laser locator and position sensor to facilitate automatic positioning of the device, ensuring that the pipeline can accurately reach the predetermined position during the deployment process, and effectively reducing labor costs and improving construction efficiency.
