Technical Field

[0001] This utility model relates to a composite winding and unwinding device, and more particularly to a composite winding and unwinding device for laying dehumidification pipelines for main cables of suspension bridges, belonging to the field of pipeline engineering construction process equipment design and manufacturing technology. Background Technology

[0002] Most current pipeline laying devices are simple frames that support the pipelines for external laying. Their structure is relatively simple, making it inconvenient to install and fix the pipeline frame during use. The pipeline frame is prone to displacement during use, affecting the laying effect and reducing its practicality.

[0003] Dehumidification pipeline racks used for main cable dehumidification are usually simple welded cross-shaped pipe laying racks. They need to be transported in conjunction with other hoisting equipment and cannot be effectively fixed. They require manual assistance, which is risky and inefficient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a composite pipe winding and unwinding device for laying dehumidification pipelines for main cables of suspension bridges, which can achieve transportation within a certain distance, improve the efficiency of pipe winding and unwinding, and ensure construction safety.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a composite reeling and laying device for the dehumidification pipeline of the main cable of a suspension bridge. The composite reeling and laying device includes a movable support base, a reeling and laying system, and a laying and laying system. The reeling and laying system is rotatably hinged to the top of the movable support base around its own axial centerline. The laying and laying system is arranged at the end of the reeling and laying system where no pipe-laying tripod is set. During the laying and laying process, the pipeline stored in the reeling and laying system is laid to the designated position of the pipeline to be installed on the main cable of the suspension bridge through the laying and laying system with the cooperation of the construction operators. After the pipeline is laid, the pipeline that is not installed is cut off from the pipeline to be installed through the laying and laying system and its end located in the reeling and laying system is fixed.

[0006] Furthermore, the mobile support base includes wheels, a cross-shaped support frame, and support rods. The support rods are vertically supported at the hinge of the cross-shaped support frame. At least one wheel is arranged at each end of the two horizontal bars of the cross-shaped support frame. At least one of the wheels is equipped with a self-locking mechanism. The tube placement system is hinged to the top of the support rods.

[0007] The preferred embodiment of the above scheme is that the pipe placement system includes at least a steering wheel and a pipe placement frame. The pipe placement frame tripod is set at one end of the pipe placement frame, and the pipe laying system is set at the other end of the pipe placement frame. The pipe placement frame is movably arranged on the top of the mobile support base frame via the steering wheel. During the pipe laying construction, the pipeline to be laid is placed into the pipe placement frame from the end with the pipe placement frame tripod. The pipe placement frame storing the pipeline can be arranged horizontally or vertically on the top of the mobile support base frame via the steering wheel.

[0008] Furthermore, the pipe-laying frame includes a stationary section and a rotating section. The stationary and rotating sections are connected as a single movable unit via a steering wheel, which is also hinged to the top of the mobile support base. A tripod for the pipe-laying frame is positioned at the free end of the stationary section, and the pipe-laying system is located at the free end of the rotating section. During the pipe-laying process, the pipeline is placed from the free end of the stationary section onto the pipe-laying frame with the assistance of the tripod. The laying end of the pipeline passes through the pipe-laying system and extends out of the composite roll pipe-laying device. With the cooperation of the construction operators, the pipeline is laid to the designated location on the main cable of the suspension bridge where the pipeline needs to be installed.

[0009] The preferred embodiment of the above scheme is that the steering wheel includes at least a steering buckle and an intermediate steering sleeve. A rotary drive motor is installed inside the intermediate steering sleeve. Both the stationary section pipe placement frame and the rotating section pipe placement frame include a central support drive shaft and at least three angular rods. Two central support drive shafts are connected to the intermediate steering sleeve from both ends. At least the central support drive shaft located on the rotating section pipe placement frame is connected to the rotary drive motor. The number of steering buckles is equivalent to the number of angular rods. Each angular rod is connected to the corresponding steering buckle from both ends. During the pipe placement construction, the rotating section pipe placement frame can rotate around its own axial centerline under the output driving force of the rotary drive motor. The pipe placement frame in the horizontal stationary state or the vertical use state can be locked to the top of the mobile support base frame through the corresponding steering buckles.

[0010] Furthermore, the pipe laying system includes at least a pipe laying wheel, a crimping connector holder, and a traction device. The traction device is arranged on the pipe laying wheel via the crimping connector holder, and the pipe laying wheel is arranged at the free end of the rotating section pipe laying frame. During the pipe laying construction, the installation end of the pipeline stored on the pipe laying frame extends out of the traction device with the cooperation of the crimping connector holder and determines the starting direction of the pipeline laying.

[0011] The preferred embodiment of the above scheme is that the traction device consists of a cylinder that is larger at the top and smaller at the bottom, and the crimping connector holder consists of two semi-circular devices and two telescopic arms. The lower ends of the two telescopic arms, which are arranged in a figure-eight shape, are fixedly connected to the corresponding outer edges of the pipe-laying wheel. The cylinder, which is arranged at the upper end of the two telescopic arms through the two semi-circular devices, can rotate freely within the corresponding space with the cooperation of each telescopic arm. During the pipe-laying construction, the installation end of the pipeline that extends from the large end of the cylinder and extends from the small end of the cylinder is positioned according to the starting direction of the arrangement of each telescopic arm with the cooperation of each semi-circular device.

[0012] Furthermore, a rubber mesh is installed at the top of the cylinder, and an elliptical inclined anti-retraction ring is installed in the middle of the cylinder; during the pipe laying construction, the pipeline being laid is protected from the swinging state caused by sudden retraction with the cooperation of the elliptical inclined anti-retraction ring and the rubber mesh.

[0013] The preferred embodiment of the above scheme is that the pipe laying system also includes a cutting saw, which is arranged on the pipe laying wheel in a position appropriate to the clamping device of the cutting saw; after the laying is completed, the conduit on the pipe rack and the pipe to be laid out are cut and separated by the cutting saw.

[0014] The beneficial effects of this utility model are as follows: The technical solution provided in this application sets up a composite pipe rolling and unloading device including a movable support base, a pipe rolling placement system, and a pipe laying system. The pipe rolling placement system is rotatably hinged to the top of the movable support base around its own axial center line. The pipe laying system is arranged at the end of the pipe rolling placement system where the pipe placement tripod is not set up. Then, during the pipe laying construction, the pipeline stored in the pipe rolling placement system is laid to the designated position where the pipeline needs to be installed on the main cable of the suspension bridge through the pipe laying system with the cooperation of the construction operators. After the pipeline is laid out, the pipeline that is not installed is cut off from the pipeline that is to be installed through the pipe laying system and its end located in the pipe rolling placement system is fixed. This effectively solves the technical problems of existing technologies that use simple cross-shaped pipe laying racks for pipeline storage and then manually arrange the pipelines, which cannot be transported using the cross-shaped pipe laying racks and require manual assistance during pipeline laying, resulting in high risks and low efficiency. By using the composite pipe rolling and laying device of this application to lay pipelines, it is possible to achieve pipeline transportation within a certain distance, improve the efficiency of pipeline rolling and laying, and ensure construction safety.

[0019] like Figures 1-5 This invention provides a composite pipe-winding and unwinding device for laying dehumidification pipelines on the main cable of a suspension bridge, which enables transportation over a certain distance, improves the efficiency of pipe winding and unwinding, and ensures construction safety. The composite pipe-winding and unwinding device includes a movable support frame, a pipe-winding placement system, and a pipe-laying system. The pipe-winding placement system is rotatably hinged to the top of the movable support frame around its own axial centerline. The pipe-laying system is located at the end of the pipe-winding placement system where the tripod 2 is not installed. During the pipe-laying construction, the pipeline stored in the pipe-winding placement system is laid to the designated location on the main cable of the suspension bridge where the pipeline needs to be installed, with the cooperation of the construction operators, through the pipe-laying system. After the pipeline is laid out, the pipeline not yet installed is cut off from the pipeline to be installed by the pipe-laying system, and its end located within the pipe-winding placement system is fixed. The technical solution provided in this application involves setting up a composite pipe-laying device that includes a movable support base, a pipe-laying system, and a pipe-laying and laying system. The pipe-laying system is rotatably hinged to the top of the movable support base around its own axial centerline. The pipe-laying and laying system is positioned at the end of the pipe-laying system where the pipe-laying tripod is not installed. During the pipe-laying construction process, the pipes stored in the pipe-laying system are laid out to the designated positions where the main cable of the suspension bridge needs to be installed, with the cooperation of the construction operators, through the pipe-laying and laying system. After the pipes are laid out, the pipes that are not yet installed are cut off from the pipes to be installed by the pipe-laying and laying system, and the end of the pipe that is located in the pipe-laying system is fixed. This effectively solves the technical problems of existing technologies that use simple cross-shaped pipe laying racks for pipeline storage and then manually arrange the pipelines, which cannot be transported using the cross-shaped pipe laying racks and require manual assistance during pipeline laying, resulting in high risks and low efficiency. By using the composite pipe rolling and laying device of this application to lay pipelines, it is possible to achieve pipeline transportation within a certain distance, improve the efficiency of pipeline rolling and laying, and ensure construction safety.

[0020] Accordingly, to facilitate pipeline laying and the fabrication of the composite pipe laying device, the mobile support frame of this application includes wheels, a cross-shaped movable support frame 4, and a support vertical rod 5. The support vertical rod 5 is vertically supported at the hinge of the cross-shaped movable support frame 4. At least one wheel is arranged at each end of the two horizontal bars of the cross-shaped movable support frame 4, and at least one of the wheels is equipped with a self-locking mechanism. The pipe laying system is movably hinged to the top of the support vertical rod 5. The pipe laying system of this application also includes at least a steering wheel and a pipe placement frame. The pipe placement frame tripod 2 is set at one end of the pipe placement frame, and the pipe laying system is set at the other end of the pipe placement frame. The pipe placement frame is movably arranged on the top of the mobile support frame via the steering wheel. During the pipe laying construction, the pipeline to be laid is placed into the pipe placement frame from the end with the pipe placement frame tripod 2. The pipe placement frame storing the pipeline can be arranged horizontally or vertically on the top of the mobile support frame via the steering wheel. The pipe laying system of this application includes at least a pipe laying wheel 1, a crimping connector holder, and a traction device 11. The traction device 11 is arranged on the pipe laying wheel 1 through the crimping connector holder, and the pipe laying wheel 1 is arranged at the free end of the rotating section pipe laying frame 7. During the pipe laying construction, the installation end of the pipeline stored on the pipe laying frame extends out of the traction device 11 with the cooperation of the crimping connector holder and determines the starting direction of the pipeline laying. More specifically, the pipe-laying frame of this application includes a stationary pipe-laying frame 6 and a rotating pipe-laying frame 7. The stationary pipe-laying frame 6 and the rotating pipe-laying frame 7 are connected as a movable whole by a steering wheel and are hinged to the top of a movable support base frame by the steering wheel. The pipe-laying frame tripod 2 is arranged at the free end of the stationary pipe-laying frame 6, and the pipe-laying system is set at the free end of the rotating pipe-laying frame 7. During the pipe-laying construction, the pipeline is placed from the free end of the stationary pipe-laying frame 6 onto the pipe-laying frame with the cooperation of the pipe-laying frame tripod 2. The laying end of the pipeline passes through the pipe-laying system and extends out of the composite roll pipe-laying device. With the cooperation of the construction operators, the pipeline is laid to the designated position where the pipeline needs to be installed on the main cable of the suspension bridge through the pipe-laying system. The steering wheel of this application includes at least a steering buckle 8 and an intermediate steering sleeve 9. A rotary drive motor is installed inside the intermediate steering sleeve 9. The stationary section pipe placement frame 6 and the rotating section pipe placement frame 7 each include a central support drive shaft and at least three angular rods. The two central support drive shafts are connected to the intermediate steering sleeve 9 from both ends. The central support drive shaft located at least on the rotating section pipe placement frame 7 is connected to the rotary drive motor. The number of steering buckles 8 is equivalent to the number of angular rods. Each angular rod is connected to the corresponding steering buckle 8 from both ends. During the pipe laying construction, the rotating section pipe placement frame 7 can rotate around its own axial centerline under the cooperation of the driving force output by the rotary drive motor. The pipe placement frame in the horizontal stationary state or the vertical use state can be locked to the top of the mobile support base frame through the corresponding steering buckle 8.

[0021] Furthermore, to improve the anti-retraction effect, the traction device 11 is composed of a cylinder that is larger at the top and smaller at the bottom. The clamping joint holder consists of two semi-circular devices 10 and two telescopic arms 12. The lower ends of the two telescopic arms 12, arranged in a figure-eight shape, are fixedly connected to the corresponding outer edges of the pipe-laying wheel 1. The cylinder, which is positioned above the two telescopic arms 12 by the two semi-circular devices 10, can rotate freely within the corresponding space with the cooperation of each telescopic arm 12. During the pipe-laying construction, the installation end of the pipeline extending from the large end of the cylinder and extending from the small end of the cylinder is positioned according to the starting direction of its arrangement by the cooperation of each telescopic arm 12 and each semi-circular device 10. A rubber net 13 is also provided at the top of the cylinder, and an elliptical oblique anti-retraction ring 14 is provided in the middle of the cylinder. During the pipe-laying construction, the pipeline being laid out is protected from sudden retraction and swaying caused by the cooperation of the elliptical oblique anti-retraction ring 14 and the rubber net 13. The pipe laying system also includes a cutting saw 15, which is positioned on the pipe laying wheel 1 to accommodate the clamping device of the cutting saw 15. After the laying is completed, the conduit on the pipe rack and the pipe to be laid are cut and separated by the cutting saw 15.

[0022] In summary, the technical solution provided in this application also has the following advantages:

[0023] Equipped with anti-winding and anti-retraction functions, the device can assist in pipeline cutting and joint crimping installation, improving pipeline rolling and unrolling efficiency and ensuring construction safety.

[0024] Example 1

[0025] This application provides a cable winding and pipe laying device to achieve efficient and safe pipe laying. The device has anti-winding traction function and anti-retraction function. At the same time, the device can be used to assist in pipe cutting and joint crimping installation, thereby improving the efficiency of pipe laying and ensuring construction safety.

[0026] I. Structural Overview

[0027] The conduit laying system includes a laying wheel, a cutting saw, a traction device, a crimping connector holder, and an anti-retraction ring. The laying wheel secures the conduit, the cutting saw cuts the conduit, and the traction device is a cylindrical structure, wider at the top and narrower at the bottom, connected to the laying wheel via the crimping connector holder. The crimping connector holder consists of two semi-circular devices and a telescopic arm, allowing for free rotation within space. A rubber mesh is installed at the top of the cylinder, and an elliptical, angled anti-retraction ring is located in the middle. The traction device fixes the initial direction of the conduit, while the top rubber mesh and the middle anti-retraction ring effectively prevent the conduit from swinging and causing safety issues due to sudden retraction.

[0028] The anti-retraction ring mainly utilizes the downward drag force generated when the pipeline retracts to pull the bottom of the anti-retraction ring downwards and clamp it to a certain position in the cylindrical structure of the traction device, thereby causing the pipeline to change direction, locking the pipeline, reducing the pipeline retraction speed, or even stopping the pipeline retraction.

[0029] II. Technical Solution

[0030] 1. Pipeline placement: Place the pipeline from one side of the stationary pipe rack, while simultaneously winding the pipe end around the pipe-laying wheel 1-2 times. Pull the starting end of pipe 1 out from the outlet of the pipe-laying wheel.

[0031] 2. Traction device fixation: Based on factors such as the pipe laying direction and operating height, fix the tilt angle of the traction device by using the clamping connector, and introduce the pipe laying start end into the traction device and pass through the internal anti-retraction ring.

[0032] 3. Pipe laying: Turn on the steering wheel motor. With the pull of the operator in front and the rotation of the pipe laying frame, the pipeline can be laid easily and efficiently.

[0033] 4. Pipeline cutting and crimping installation: After the pipeline is laid, the pipeline is cut with the saw on the pipeline laying wheel, and then the pipeline is taken out from the traction device. At the same time, the pipeline is fixed with the crimping clamp, and finally the pipeline crimping is installed.
