[0036] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0037] like Figures 1-3As shown, an automated installation device for concrete socket pipes includes a construction vehicle 1 and a pipe transport vehicle 2. The construction vehicle has a power box inside its cargo compartment, a pipe hoisting mechanism 3 on the top of the cargo compartment, a construction port on the front side of the cargo compartment floor, and a pipe docking mechanism 4 on the front side of the cargo compartment, corresponding to the construction port. An operating platform 5 is located on the rear side of the cargo compartment floor, and detachable steps 6 are provided corresponding to the operating platform and the construction port. The power box provides power support for the pipe hoisting mechanism and the pipe docking mechanism. The pipe transport vehicle carries the concrete socket pipes 7 to be installed and follows the construction vehicle.

[0038] It also includes a PLC controller, which is electrically connected to the pipe hoisting mechanism and the pipe docking mechanism to control the pipe hoisting and installation.

[0039] like Figure 6 As shown, the pipeline hoisting mechanism includes a traveling frame 8 and a hoisting assembly. The traveling frame is a T-shaped rod structure, with transverse rods arranged along the centerline of the top of the carriage and longitudinal rods passing through one side of the carriage and corresponding to the pipeline transport vehicle. The hoisting assembly includes electric traveling wheels 9, fixed pulleys 10, and a winch. The electric traveling wheels are installed on the traveling frame, and the fixed pulleys are suspended from the bottom of the electric traveling wheels. The winch is installed on the carriage, and a wire rope is wound on the winch. The free end of the wire rope passes over the fixed pulley and connects to the hook.

[0040] The pipeline connection mechanism includes a longitudinal sliding load-bearing plate 11, a support rod 12, a telescopic pull-back rod 13, and a push jack 14. The inner wall of the front side of the carriage is connected to the longitudinal sliding load-bearing plate through a guide sliding assembly. The support rod is installed on the longitudinal sliding load-bearing plate through a fixed support 15. The support rod and the fixed support are connected by an embedded intelligent ball hinge. Support umbrella frames 16 are provided on the support rod at intervals. There are two telescopic pull-back rods, which are symmetrically arranged on the left and right sides above the support rod. One end is fixed to the longitudinal sliding load-bearing plate, and the other end is a right-angle elbow structure. The push jack is symmetrically arranged above and below the fixed support.

[0041] Protective hydraulic cylinders are installed on both sides of the longitudinal sliding load-bearing plate. A transverse protective plate 17 is installed at the end of the telescopic rod of the protective hydraulic cylinder. The spacing of the transverse protective plates is adjusted by the protective hydraulic cylinders. During pipeline installation, trenches are prone to collapse and other safety accidents; the transverse protective plates ensure a safe working environment for personnel. A crash barrier 18 is installed on the longitudinal sliding load-bearing plate corresponding to the bottom of the push jack to prevent damage to the equipment from hitting stones or protrusions in the trench during downward movement.

[0042] like Figure 4As shown, the supporting umbrella frame includes a hydraulic clamp assembly, an umbrella-shaped frame, and rubber wheels 19. The hydraulic clamp assembly includes a fixed clamp 20, a movable clamp 21, and a clamp hydraulic cylinder 22. Both the fixed and movable clamps are fitted onto the support rod. The fixed clamp is fixedly connected to the support rod by screws. The clamp hydraulic cylinder is fixed to the fixed clamp. The end of the telescopic rod is connected to the movable clamp. The umbrella-shaped frame includes multiple pairs of support umbrella poles 23 and connecting rods 24 that are hinged together. One end of the support umbrella pole is hinged to the fixed clamp, and the other end is equipped with a rubber wheel. One end of the connecting rod is hinged to the movable clamp, and the other end is hinged to the support umbrella pole. The multiple support umbrella poles and connecting rods are evenly spaced along the circumference of the fixed and movable clamps. The clamp hydraulic cylinder drives the movable clamp to slide laterally along the support rod, causing the umbrella-shaped frame to close or open, adjusting the opening angle to accommodate the diameter of the concrete socket pipe being received.

[0043] It also includes a laser alignment mechanism, which comprises a laser instrument 25 and a target plate 26. The laser instrument is mounted at the center of the end of the support rod, and the target plate has an alignment point at its center, mounted at the tail end of the previously installed concrete socket pipe. The laser instrument and the target plate together form a precision measurement system to ensure accurate connection of the concrete pipe opening.

[0044] like Figure 5 As shown, the guide sliding assembly includes a gear 27, a rack 28, and a guide wheel 29. The gear is installed at the bottom of the front side panel of the carriage. A rack is laid on the front end face of the longitudinal sliding load-bearing plate and meshes with the gear. A vertical guide hole is provided on the front side panel of the carriage. The guide wheel contacts the outer wall of the front side panel of the carriage and is connected to the longitudinal sliding load-bearing plate through a crossbar 30. The rotation of the gear drives the longitudinal sliding load-bearing plate to move up and down.

[0045] The automated installation of concrete socket pipes using this device includes the following steps:

[0046] S1) After a section of the pipeline trench is completed, the construction vehicle and the pipeline transport vehicle are moved to the top of the pipeline trench. The pipeline transport vehicle is parked under the traveling frame and waits. The concrete socket pipe is lifted from the pipeline transport vehicle by a winch and wire rope. The PLC controller controls the electric traveling wheels to move along the traveling frame to transport the concrete socket pipe to and through the support rod.

[0047] S2) The support umbrella on the starting support rod of the PLC controller is slowly opened until the rubber wheel is in stable contact with the inner wall of the concrete socket pipe. The wire rope of the winch is then removed, and a person stands on the operating platform to install the rubber ring at the pipe opening of the concrete socket pipe.

[0048] S3) The PLC controller turns on the laser. The operator manually installs the target plate at the tail end of the pre-installed concrete socket pipe. The PLC controller controls the longitudinal sliding load-bearing plate to slide downwards, and at the same time, the hydraulic safety guard plate also moves downwards to form a safety guard. By adjusting the position of the support rod, the downward movement stops when the laser is directly aligned with the center of the target plate.

[0049] S4) Remove the target plate. The PLC controller starts the hydraulic jack and telescopic pull rod. The telescopic pull rod extends forward, and the elbow will tightly lock the front concrete socket pipe. The hydraulic jack applies a thrust to the concrete socket pipe to be installed. The concrete socket pipe moves forward through the rubber wheels on the support frame until it is tightly engaged with the front concrete socket pipe and then stops.

[0050] S5) Manually descend into the trench via a ladder, install pads under the concrete socket pipe to fix the pipe, and seal the joint of the two pipes with mortar.

[0051] S6) The PLC controller controls the retraction support umbrella frame, and the entire device moves in the direction of trench installation. If the pipeline is arc-shaped, the pipe tail is moved by the support rod during the process to ensure that the pipe tail is offset in the turning direction. After the above work is completed, the longitudinal sliding load-bearing plate moves upward to restore the original state.

[0052] S7) Repeat the above steps to install the next concrete socket pipe.
