[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a lifting device for transporting large-diameter pipelines.
[0020] Reference Figure 1 , Figure 2 and Figure 3 The lifting device for transporting large-diameter pipelines includes a load-bearing chassis 4 for loading, the interior of which is a hollow square box body, crawler travel assemblies 41 are arranged on both sides of the load-bearing chassis 4, a lift 3 is fixedly installed on the upper surface of the load-bearing chassis 4, the lower layer of the lift 3 is fixedly connected to the upper surface of the load-bearing chassis 4, the upper layer of the lift 3 is fixedly connected to a lifting chassis 2, the upper surface of the lifting chassis 2 is rotatably connected to a rotating disk 21 through a bearing, and the upper end of the rotating disk 21 is fixedly connected to a movable base 16.
[0021] Reference Figure 2The upper end of the movable base 16 is fixedly connected with a fixing assembly 1, and the fixing assembly 1 includes two fixing frames 17 fixed to the upper surface of the movable base 16, and the two fixing frames 17 are arranged along the axial direction of the pipeline. An arc-shaped notch for the pipeline to abut is opened in the middle position of the fixing frame 17, and a fixing ring 11 is fixedly connected to one end of the fixing frame 17, and a ratchet tightener 12 is fixedly connected to the other end of the fixing frame 17. A flat lifting belt 18 is installed in the ratchet tightener 12, and the other end of the flat lifting belt 18 is connected to the fixing ring, so that the flat lifting belt 18 can be tightened by the ratchet tightener 12. The flat lifting belt 18 is provided with a rubber sleeve, which can increase the friction between the flat lifting belt 18 and the pipeline, and can better reduce the sliding of the pipeline during transportation. When the pipeline is placed on the fixing frame 17, the length of the flat lifting belt 18 can be adjusted by adjusting the ratchet tightener 12, so that the pipeline can be tied to the fixing frame 17 to prevent the pipeline from shaking during transportation.
[0022] Reference Figure 2 Two fixing rods 13 are arranged on the upper surface of the fixing frame 17. The fixing rods 13 are cylindrical. The two ends of the fixing rods 13 are respectively fixedly connected with extension blocks 14. The upper surface of the fixing frame is provided with a plurality of positioning holes 15 for the extension blocks 14 to be plugged in. Before placing the pipeline, the position of the fixing rods 13 can be adjusted to adapt to pipelines of different sizes, so as to prevent the pipeline from rolling on the upper surface of the fixing frame 17 when placing the pipeline.
[0023] Among them, the track travel component 41 includes a track, a driving wheel, a sprocket and a driving source. The working principle of the track travel component is mainly to drive the sprocket to move through the driving wheel, and then move the chain connected to the sprocket, and then move the track connected to the chain to realize the movement of the vehicle; when the lifting device for large-diameter pipeline transportation needs to turn, the tracks on both sides rotate in different directions. When turning, two independent driving sources are used to transmit power to the two tracks respectively. The track can be freely turned on the ground by rotating one track forward and the other track backward, so it can adapt well to various narrow road environments, so that the track is more maneuverable when turning, so that the device of the present application is maneuverable in a small space.
[0024] By setting up a lift 3 between the load chassis 4 and the lifting chassis 2, when the pipeline passes through a road surface with a height difference, the pipeline can be kept level by adjusting the lifting and lowering of the lift 3 to prevent the pipeline from slipping; by rotating the rotating disk 21 connected on the upper surface of the lifting chassis 2, the crawler travel assembly 41 can rotate during transportation without affecting the pipeline above.
[0025] Reference Figure 2In order to more conveniently control the movement of the device of the present application, a controller is installed on one side of the load-carrying chassis 4. A battery box for providing power to the device of the present application is installed in the load-carrying chassis 4. The battery box is connected to the power supply circuit of the controller, the elevator and the crawler travel component. The controller is connected to an adaptive control handle 5 through a wireless module. The control handle 5 is correspondingly equipped with various functional button switches for realizing the above-mentioned forward and backward, left and right steering and lifting functions. When the pipeline is installed, the control module on the control handle 5 makes the control handle 5 send a control signal, and the controller 42 receives and responds to the signal, so that the lifting device for large-diameter pipeline transportation can be controlled in various terrains.
[0026] Usage steps: First, two devices of the present application are needed to transport a pipe. First, place the two devices of the present application near the two ends of the pipe, then use the control handle 5 to adjust the elevator 3 to a position convenient for placing the pipe, then adjust the fixing rod 13 to a suitable position according to the diameter of the pipe, then place the ends of the pipe on the arc-shaped notches of the fixing frame 17 respectively, then use the ratchet tightener 12 to tighten the flat lifting belt to complete the fixation of the pipe. After the installation is completed, the device of the present application can be remotely controlled by the control handle 5 to transport the pipe to the destination.
[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
