Description

Technical Field

[0001] This invention relates to the field of pipeline lifting technology, specifically to a lifting device for building pipeline installation. Background Technology

[0002] High-altitude installation machinery for large-diameter pipelines is only used as auxiliary equipment for short-distance transportation and material lifting within limited heights. Construction personnel should work on a safe operating platform. This equipment can assist in construction within confined spaces, improving efficiency, ensuring safety, and enhancing quality. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a lifting device for building pipeline installation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a lifting device for building pipeline installation, comprising a housing and a moving mechanism. The housing is used to move the entire device to a suitable position, enabling the device to transport and lift pipelines. The moving mechanism is protected by the housing. A warning light is installed on the housing; when personnel approach the working point m of the device, an audible and visual alarm will sound, alerting the personnel to the danger zone. When personnel approach the working point m of the device, the device will stop operating to prevent accidental injury. Four pipeline lifting rods are also installed on the housing, grouped together. A placement platform is installed between the four pipeline lifting rods for placing pipelines. A pipeline lifting mechanism is also installed between the four pipeline lifting rods, equipped with a pipeline clamping mechanism and a pipeline fixing clamping mechanism for lifting and clamping the pipelines. A top plate is also installed between the four pipeline lifting rods, with a pipeline conveying mechanism installed at the bottom of the top plate for conveying the lifted pipelines. Grilles are fixedly installed on the sides of the four pipeline lifting rods for protection.

[0005] Preferably, each of the four pipe lifting rods has a movable groove, and two lifting machines are installed in each movable groove. The four lifting machines drive the movable plate to move up and down. When the movable plate moves up and down, it is convenient for the pipe clamping mechanism to clamp the pipe and is also used for pipe height positioning. The other four pipe lifting rods drive the top plate to move up and down. Through the up and down movement of the top plate, the pipe conveying mechanism acts on the pipe, driving the pipe to move and transport the pipe.

[0006] Preferably, a placement platform is fixedly installed at the bottom of the four pipe lifting rods, and the upper surface of the placement platform is designed as a placement surface, on which the pipes are stacked and moved toward the center.

[0007] Preferably, the pipe lifting mechanism includes a movable plate, a pipe moving groove is provided in the middle of the movable plate for the pipe to move up and down, and pipe clamping mechanisms are rotatably installed on both sides of the pipe moving groove; the pipe clamping mechanism includes a rotating rod, which is rotatably installed on both sides of the pipe moving groove, and a rotating shaft and a lever are fixedly installed on the rotating rod; a groove is provided on the side of the pipe moving groove for the movement of the lever.

[0008] Preferably, the pipe clamping mechanism further includes a rotating rod, a shaft, and an arc-shaped rod. The shaft is installed at the connection between the groove and the pipe moving groove and rotates with the rotating rod. An arc-shaped rod is fixedly installed on the shaft, and the arc-shaped rod is designed to be arc-shaped.

[0009] Preferably, the pipe fixing clamping mechanism includes a base, which is fixedly mounted on a movable plate. A support rod is rotatably mounted on the base via a hinge, and a fixing plate is fixedly mounted on the support rod. A clamping and fixing wheel is mounted on the side of the fixing plate near the pipe.

[0010] Preferably, there are three pipe fixing and clamping mechanisms, which are alternately arranged on both sides of the pipe moving groove. The support rod is arc-shaped and inclined to one side of the pipe moving groove. The fixing plate is designed to be arc-shaped to wrap the pipe. The clamping and fixing wheel is rotated on the fixing plate, and the rotation direction of the clamping and fixing wheel is consistent with the moving direction of the pipe after it is lifted.

[0011] Preferably, a hydraulic press is mounted on the protruding side of the support rod via a hinge. The hydraulic press is fixedly mounted on the movable plate and provides support force to the support rod, ensuring the stability of the pipe after it is wrapped by the fixed plate.

[0012] Preferably, the pipeline conveying mechanism includes a fixed plate and a movable wheel. The fixed plate is fixedly installed at the bottom of the top plate, and the movable wheel is rotatably installed between the two fixed plates. The movable wheel is designed to be spindle-shaped.

[0013] Compared with the prior art, the present invention provides a lifting device for building pipeline installation, which has the following advantages: 1. This building pipeline installation lifting equipment is fully automated from pipeline stacking, clamping to conveying. The equipment can replace manual handling, reducing labor costs. At the same time, through multiple innovations, the equipment solves the industry pain points of "high safety risks, difficult positioning, and poor transportation stability" in the installation of large-diameter pipelines. It is especially suitable for large-scale building electromechanical projects with tight schedules and high precision requirements, and has both economic benefits and engineering quality assurance capabilities.

[0014] 2. The lifting equipment for building pipeline installation has a warning light that provides audible and visual alarms within a 3m range and equipment suspension within a 1m range, creating a dual safety barrier of "early warning and protection" to prevent personnel from accidentally touching moving parts such as clamping or lifting, which could cause squeezing or collision injuries. The grille on the side of the pipeline lifting rod prevents debris from entering and coming into contact with personnel. Combined with the outer shell to protect the moving mechanism, it reduces equipment failure and operational risks and complies with building construction safety regulations.

[0015] 3. The lifting equipment for building pipeline installation uses a lifting machine to drive a moving plate to vertically lift the pipeline, and the top plate drives a spindle-shaped moving wheel to complete the horizontal transfer. No manual transfer is required, and the "lifting → translation" process is completed in a single flow, which shortens the installation time of a single pipeline. The spindle-shaped moving wheel adapts to different pipe diameters, and the contact point is always located in the middle of the wheel body. It can be compatible with large-diameter pipelines without adjusting the equipment, reducing the time spent on changing the type.

[0016] 4. The lifting equipment for building pipe installation uses an inclined platform to allow pipes to naturally stack towards the center, automatically aligning the axes without the need for additional positioning devices. This solves the problem of clutter when stacking multiple pipes and improves the success rate of clamping.

[0017] 5. The lifting equipment for building pipeline installation has a ring-shaped clamping mechanism on both sides of the pipeline moving groove, which evenly distributes the weight of the pipeline and avoids tilting or falling off caused by single-point force. It is especially suitable for long-distance lifting. The hydraulic press compensates for the force on the support rod in real time to cope with changes in pipeline weight or lifting vibration, ensuring that the pipeline remains stable during start-up, shutdown and speed change, and reducing installation errors caused by shaking.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to Figure 1-2 .

[0022] A lifting device for building pipeline installation includes a housing 10 and a moving mechanism 11. The housing 10 is used to move the entire device to a suitable position and enable the device to be used for pipeline transportation and lifting. The device is characterized in that: the housing 10 is installed outside the moving mechanism 11 to protect the housing 10; a warning light 12 is installed on the housing 10 for alerting personnel. When personnel approach the device within 3 meters of it during operation, an audible and visual alarm will sound to alert them to the danger zone; when personnel approach the device within 1 meter of it during operation, the device will stop working to prevent accidental injury. The outer shell 10 is also equipped with four pipe lifting rods 14, which are divided into two groups. A placement platform 13 is installed between the four pipe lifting rods 14 for placing pipes. A pipe lifting mechanism 16 is also installed between the four pipe lifting rods 14. The pipe lifting mechanism 16 is equipped with a pipe clamping mechanism 20 and a pipe fixing clamping mechanism for lifting and clamping the pipe. A top plate 17 is also installed between the four pipe lifting rods 14, and a pipe conveying mechanism is installed at the bottom of the top plate 17 for conveying the lifted pipes. The sides of the four pipe lifting rods 14 are fixedly fitted with grilles 18 for protection.

[0023] The moving mechanism 11 serves as a power source, driving the housing 10 to move to a designated position; the housing 10 encloses and protects the moving mechanism 11, ensuring its stable operation in complex construction environments.

[0024] The system detects the distance to personnel using sensors. When a person enters a 3-meter range, an audible and visual alarm is triggered. When a person enters a 1-meter danger zone, the linkage control system suspends the operation of the equipment to prevent accidental injury caused by clamping, lifting, or other actions.

[0025] Four pipe lifting rods 14 are divided into two groups to form a frame structure, supporting the placement platform 13; the placement platform 13 is used to temporarily store the pipes to be installed, providing a basic work position for subsequent lifting processes.

[0026] The pipe lifting mechanism 16 integrates clamping and lifting functions, and works with the conveying mechanism at the bottom of the top plate 17 to realize the vertical and horizontal transportation of the pipe from the placement platform 13 to the installation position; the grille 18 protects the side of the pipe lifting rod 14 to prevent debris from entering or personnel from accidentally touching it.

[0027] Example 2, based on Example 1, please refer to... Figure 1-3 .

[0028] Each of the four pipe lifting rods 14 has a movable groove, and each movable groove is equipped with two lifting machines 23. The four lifting machines 23 drive the movable plate 24 to move up and down. When the movable plate 24 moves up and down, it is convenient for the pipe clamping mechanism 20 to clamp the pipe, and at the same time it is used for the height positioning of the pipe. The other four pipe lifting rods 14 drive the top plate 17 to move up and down. The up and down movement of the top plate 17 causes the pipe conveying mechanism to act on the pipe, driving the pipe to move and carry out pipe transportation.

[0029] Two lifting mechanisms 23 are installed in the movable groove of each pipe lifting rod 14, and a total of four sets of lifting mechanisms 23 synchronously drive the movable plate 24 to rise and fall vertically. The movable plate 24 carries the pipe clamping mechanism 20 to adjust its height, ensuring that the clamps are aligned with the center of the pipe for precise clamping; at the same time, the height positioning function can adapt to the diameter differences of pipes of different specifications.

[0030] The pipe lifting rod 14 drives the top plate 17 to move up and down through a built-in transmission structure such as a lead screw or rack. When the top plate 17 descends to contact the pipe, the bottom transmission mechanism adheres to the pipe surface and drives the pipe to move horizontally through friction or gear meshing.

[0031] Example 3, based on Example 2, please refer to... Figure 1-2 .

[0032] A placement platform 13 is fixedly installed at the bottom of the four pipe lifting rods 14. The upper surface of the placement platform 13 is designed as a placement surface 15, and the pipes are stacked and moved towards the middle position on the placement surface 15.

[0033] The upper surface of the placement platform 13 is designed as an inclined placement surface 15 with the slope facing the center. Gravity or slight mechanical power such as rollers is used to make the pipes automatically gather in the middle, which facilitates the positioning of the subsequent clamping mechanism 20.

[0034] Example 4, based on Example 3, please refer to... Figure 1-2 .

[0035] The pipe lifting mechanism 16 includes a movable plate 24, and a pipe moving groove 25 is provided in the middle of the movable plate 24 for the pipe to move up and down. Pipe clamping mechanisms 20 are rotatably installed on both sides of the pipe moving groove 25. The pipe clamping mechanism 20 includes a rotating rod 21, which is rotatably mounted on both sides of the pipe moving groove 25. A rotating shaft and a lever are fixedly mounted on the rotating rod 21. A groove 22 is provided on the side of the pipe moving groove 25, which is used for moving the lever.

[0036] The rotating rod 21 is installed on both sides of the pipe moving groove 25 and is driven to rotate by a motor or hydraulic system. The actuating rod on the rotating rod 21 is embedded in the groove 22 and moves along the trajectory of the groove 22 when rotating, which drives the shaft 33 and the arc rod 19 to swing, thereby realizing the opening and closing of the gripper.

[0037] The vertical movement channel for the pipeline is provided, and the clamping mechanisms 20 on both sides are linked by the rotating rod 21 to clamp the outer wall of the pipeline from both sides to ensure stability during lifting.

[0038] Example 5, based on Example 4, please refer to... Figure 3-5 .

[0039] The pipe clamping mechanism 20 also includes a rotating rod 21, a shaft 33, and an arc-shaped rod 19. The shaft 33 is installed at the connection between the groove 22 and the pipe moving groove 25 and rotates with the rotation of the rotating rod 21. The arc-shaped rod 19 is fixedly installed on the shaft 33 and is designed to be arc-shaped.

[0040] The shaft 33 connects the rotating rod 21 and the arc rod 19. When the rotating rod 21 rotates, the shaft 33 swings at the connection between the groove 22 and the pipe moving groove 25, causing the arc rod 19 to clamp the pipe in an arc trajectory.

[0041] The arc-shaped design of the arc rod 19 conforms to the curved surface of large-diameter pipes, increasing the contact area, reducing local pressure, and preventing damage to the pipe surface.

[0042] Example 6, based on Example 5, please refer to... Figure 4 .

[0043] The pipe fixing clamping mechanism includes a base 27, which is fixedly installed on a movable plate 24. A support rod 28 is rotatably mounted on the base 27 via a hinge. A fixing plate 29 is fixedly installed on the support rod 28. A clamping fixing wheel 30 is installed on the side of the fixing plate 29 near the pipe.

[0044] The base 27 is fixed to the movable plate 24, and the support rod 28 can swing through the hinge to adapt to changes in pipe diameter; the fixed plate 29 swings with the support rod 28 to wrap around the pipe, and the clamping fixed wheel 30 contacts the pipe surface to prevent slippage during lifting through friction.

[0045] The protruding side of the support rod 28 is supported by the hydraulic press 26, which provides a constant clamping force to ensure that the pipe does not fall off during the lifting process.

[0046] Example 7, based on Example 6, please refer to... Figure 4 .

[0047] There are three pipe fixing clamping mechanisms, which are alternately arranged on both sides of the pipe moving groove 25. The support rod 28 is arc-shaped and inclined to one side of the pipe moving groove 25. The fixing plate 29 is designed in an arc shape to wrap the pipe. The clamping fixing wheel 30 is rotated on the fixing plate 29, and the rotation direction of the clamping fixing wheel 30 is consistent with the movement direction of the pipe after it is lifted.

[0048] Three sets of clamping mechanisms are alternately set on both sides of the pipe moving groove 25 to form a ring-shaped surrounding structure, which evenly distributes the clamping force and avoids the pipe tilting due to excessive force on a single set.

[0049] The arc design of the support rod 28 and the fixing plate 29 is adapted to the circumferential curved surface of large-diameter pipes to ensure stable clamping; the rotation direction of the clamping fixing wheel 30 is consistent with the direction of pipe movement, allowing the pipe to rotate slightly in the clamped state to adapt to angle adjustments during installation.

[0050] Example 8, based on Example 7, please refer to... Figure 4 .

[0051] A hydraulic press 26 is mounted on the protruding side of the support rod 28 via a hinge. The hydraulic press 26 is fixedly mounted on the movable plate 24 and provides support force to the support rod 28 to ensure the stability of the pipe after it is wrapped by the fixed plate 29.

[0052] When the pipe is wrapped by the fixing plate 29, the hydraulic press 26 monitors the force on the support rod 28 in real time, automatically adjusts the extension and retraction, compensates for changes in pipe weight or vibration during the lifting process, and ensures that the clamping force is constant.

[0053] The hinged connection allows the support rod 28 to swing slightly, accommodating positional deviations of the pipe during the lifting process and avoiding stress concentration caused by rigid clamping.

[0054] Example 9, based on Example 8, please refer to... Figure 1 .

[0055] The pipeline conveying mechanism includes a fixed plate 31 and a movable wheel 32. The fixed plate 31 is fixedly installed at the bottom of the top plate 17, and the movable wheel 32 is rotatably installed between the two fixed plates 31. The movable wheel 32 is designed to be spindle-shaped.

[0056] The fixing plate 31 is fixed to the bottom of the top plate 17. A spindle-shaped moving wheel 32 is installed between the two fixing plates 31. Its design with large diameter at both ends and small diameter in the middle can adapt to the center height of pipes with different diameters, ensuring that the contact point is always located in the middle of the wheel.

[0057] The moving wheel 32 is driven to rotate by a motor, and the friction force drives the pipe to move horizontally; the spindle-shaped profile guides the pipe to transport in a straight line along the axial direction, reducing deviation.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
