Description

Technical Field

[0001] This invention relates to the field of winding device technology, specifically a mobile platform type electric wrapping machine and method. Background Technology

[0002] Currently, for wrapping large objects, especially on structures with large diameters such as bridge main cables and pipelines, traditional wrapping equipment is mostly operated manually or semi-mechanized. This method has many drawbacks, such as low efficiency, high labor intensity, inability to maintain continuous wrapping tension, and poor construction stability. Furthermore, during the wrapping process, when encountering obstacles on the surface of the wrapped object (such as cable clamps or air clamps), the machine usually needs to be stopped for adjustment, further reducing construction efficiency. At the same time, the operation of traditional equipment is difficult to automate and intelligently, especially in complex construction environments, such as when the surface of the wrapped object is irregular or there are local height differences, which can easily lead to construction interruptions, increasing operational difficulty and construction costs.

[0003] In existing technologies, while some winding equipment can achieve a certain degree of automation, significant human intervention is still required when encountering obstacles on the surface of the workpiece being wound. These devices lack autonomous obstacle-crossing capabilities, and some even resort to directly crushing obstacles with their walking mechanisms, causing varying degrees of damage to both the workpiece and the walking mechanism itself. Furthermore, the complex structural design, heavy weight, and high center of gravity of existing winding equipment can easily lead to insufficient stability during operation, affecting winding quality and even posing safety hazards.

[0004] Therefore, existing winding equipment cannot fully meet the requirements of high efficiency, stability and automation for large-scale structure winding construction, especially in complex construction environments where the equipment performance is particularly inadequate. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes a mobile platform-type electric wrapping machine. This device features obstacle-crossing capability, enabling it to cross obstacles on the surface of the workpiece without contact during the wrapping process, while maintaining overall stability and ensuring the continuity and quality of the wrapping operation. Furthermore, the wrapping machine of this invention has a compact design, low center of gravity, stable operation, and stable wrapping tension, making it suitable for wrapping various large structures, significantly improving construction efficiency and reducing the need for manual intervention.

[0006] To achieve the above-mentioned technical objectives, the present invention employs the following technical means: A mobile platform-type electric wrapping machine includes: A platform frame is erected outside the component being wound, and a connection is provided between the platform frame and the component being wound: The traveling wheel assembly includes at least two sets, and multiple sets of traveling wheel assemblies are installed longitudinally on the upper part of the platform frame. The platform frame can move along the axial direction of the wound part through the traveling wheel assembly. Each set of traveling wheel assembly is connected to the platform frame through a height lifting mechanism. The height lifting mechanism can drive the traveling wheel assembly to lift or press down onto the upper surface of the wound part. The clamping mechanism is symmetrically arranged on the left and right sides inside the platform frame to clamp the entire platform frame onto the wrapped part. The rotating disk constraint frame is installed inside the platform frame via the upper longitudinal beam and the lower helical screw of the platform frame. A rotating disk is suspended on one side of the rotating disk constraint frame by a support pulley, and a reel is fixed on the rotating disk. A rotary drive unit is installed at the lower part of the platform frame and drives the rotary disk to rotate at a constant speed around the wound part through a transmission component. The rotary disk longitudinal drive assembly is installed at the bottom inner side of the platform frame and is used to drive the rotary disk constraint frame to move at a constant speed along the longitudinal direction of the platform frame together with the rotary disk. The platform moving traction assembly is used to move the entire platform frame at a constant speed along the axial direction of the wound element.

[0007] The outer circular surface of the rotating disk is provided with a ring gear; The rotary drive unit is a motor, and the motor drive shaft meshes with the ring gear through a gear.

[0008] The platform frame has two symmetrically arranged slide rails on both sides of its bottom. The two ends of each slide rail are connected to the gantry frame at the front and rear ends of the platform frame. Each slide rail is equipped with a trolley that can slide along the slide rail. The slings straddle the upper surface of the part being wound, and both ends of the slings are connected to the trolley by pins.

[0009] The rotary disk longitudinal drive assembly includes a lead screw and a lead screw drive motor. The lead screw and the lead screw drive motor are both installed on the bottom inner side of the platform frame. The rotary disk constraint frame is fixedly connected to the nut sliding pair on the lead screw.

[0010] The platform moving traction assembly includes a traction hoist and a traction wire rope. One end of the traction wire rope passes through the traction hoist and then through a steering pulley set on the wound part. The end of the traction wire rope is then fixed to a column on the opposite side of the platform frame.

[0011] The height lifting mechanism is a hydraulic cylinder. The cylinder body is fixedly connected to the upper crossbeams at the front and rear ends of the platform frame, and the telescopic shaft of the hydraulic cylinder is connected to the traveling wheel assembly.

[0012] The wheel assembly includes: a main wheel, a wheel housing, and a wheel guide support column. The main walking wheel is installed on the walking wheel housing, and the walking wheel guide support column is connected between the walking wheel housing and the platform frame.

[0013] Two sets of clamping mechanisms are symmetrically arranged on the inner sides of the gantry frame at the front and rear ends of the platform frame along the left and right sides of the part to be wound. Each clamping mechanism includes a hydraulic jack, a jack rod, and a connecting plate. The hydraulic jack abuts against the outer wall of the part to be wound through the jack rod and the connecting plate.

[0014] A wrapping method based on the aforementioned mobile platform-type electric wrapping machine. Method 1 of wrapping work: S1. The walking wheel assembly is driven down to the upper surface of the workpiece by the height lifting mechanism. The entire movable platform electric wrapping machine is suspended and supported on the workpiece by the walking wheel assembly. At the same time, the clamping mechanism clamps the entire platform frame and the workpiece together. S2. Start the rotary drive unit, the rotary disk rotates, and at the same time start the rotary disk longitudinal drive assembly; S3. The rotating disk constraint frame moves at a constant speed along the longitudinal direction of the platform frame with the rotating disk, and the wrapped part is wrapped. S4. The rotary table stops working at the front end of the platform of the movable platform electric wrapping machine. The clamping mechanism releases the entire platform frame from the wrapped part. The platform frame is moved forward to the next working position by the platform moving traction assembly and then stops moving. The rotary table longitudinal drive assembly is started to rotate in the opposite direction, so that the rotary table constraint frame drives the rotary table back to the end position of the previous wrapping. Steps S1 to S3 are repeated. Method 2 for wrapping packages: SA, the walking wheel assembly is driven down to the upper surface of the workpiece by the height lifting mechanism. The entire mobile platform electric wrapping machine is suspended and supported by the walking wheel assembly. At the same time, the clamping mechanism releases the entire platform frame from the workpiece. SB, start the rotary drive unit, the rotary table rotates, and at the same time start the platform moving traction assembly; SC, the platform frame moves forward at a constant speed, and the wrapped part is wrapped.

[0015] This invention further discloses a working method for a mobile platform-type electric wrapping machine to overcome obstacles on the surface of the wrapped part, comprising the following steps: Step 1: When a set of traveling wheels on the platform frame encounters an obstacle, the sling is straddled on the upper surface of the part being wound and close to the set of traveling wheels on the nearby obstacle. The two ends of the sling are connected to the trolley by pins. At this time, the sling can be securely connected to the entire part being wound. Step 2: A set of walking wheel assemblies near the obstacle on the platform frame is raised above the obstacle by the height lifting mechanism connected to it. At this time, the part of the movable platform electric wrapping machine near the obstacle is suspended and supported by the sling. The platform moving traction assembly is started, and the entire platform frame moves forward at a constant speed until the walking wheel assembly at the front end in the wrapping direction passes the obstacle. During the process of crossing the obstacle, the two ends of the sling slide along the slide rail through the trolley. Step 3: The method by which the rear walking wheel assembly of the platform frame crosses obstacles on the surface of the wrapped part is the same as the method by which the front walking wheel assembly crosses obstacles on the surface of the wrapped part. Beneficial effects

[0016] First, the movable platform electric wrapping machine of the present invention has a height lifting mechanism between the walking wheel assembly and the platform frame. At the same time, a sling is straddling the upper surface of the workpiece to be wrapped, and the two ends of the sling are connected to the trolley by pins. The platform moving traction assembly can realize the front and rear main walking wheels crossing the obstacle of the workpiece to be wrapped without contact, thus preventing the walking wheel assembly from being damaged due to the obstacle.

[0017] Secondly, the platform-type electric wrapping machine of the present invention weighs about 2 tons, and the rotary drive unit and the longitudinal drive assembly of the rotary disk, which account for a large proportion of the weight, are installed at the bottom of the entire wrapping machine. This results in the overall center of gravity of the wrapping machine being at the bottom of the workpiece being wrapped. The machine automatically stands vertically on the workpiece being wrapped, with good balance, ensuring that no tilting occurs.

[0018] Third, the longitudinal drive assembly of the rotary disk adopts a lead screw and a lead screw drive motor, which can achieve uniform and adjustable wrapping speed. Attached Figure Description

Figure 2 for Figure 1 Side view. Detailed Implementation

[0020] The technical solution of the present invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. Example

[0021] like Figure 1 As shown, in this embodiment, the component to be wrapped is the main cable of a bridge, and the structure of the movable platform type electric wrapping machine is as follows: The mobile platform wrapping machine consists of the following main components: platform frame, wheel assembly, height lifting mechanism, rotating disc constraint frame, rotating disc, belt reel, clamping mechanism, slide rail, trolley, sling, rotating disc longitudinal drive assembly, and platform movement traction assembly.

[0022] Platform Frame ---- The platform frame has dimensions of (4000~6000)*(2000~2500)*(3000~3500) and is welded from steel square tubes. It serves as the carrier skeleton of the entire platform-type electric wrapping machine.

[0023] The platform frame can move along the axial direction of the wound part through the walking wheel assembly. In this embodiment, the walking wheel assembly consists of a main walking wheel made of polyurethane material, a walking wheel housing, and a walking wheel guide support column. In this embodiment, the main walking wheel has a concave surface, and the curvature of the concave surface matches the curvature of the main cable surface, so it can roll along the upper surface of the main cable.

[0024] As another embodiment, the walking wheel assembly includes multiple walking wheels, namely two walking wheels located on the top of the wrapped part and two walking wheels on the left and right sides. The three walking wheels are combined into one unit by a wheel frame to enable the platform frame to be guided and moved along the axial direction of the wrapped part.

[0025] The height lifting mechanism consists of a hydraulic cylinder, high-pressure oil pipe, hydraulic station and hydraulic control box. The hydraulic cylinder can extend and retract longitudinally along the cylinder body. The hydraulic cylinder has a capacity of 1T~5T and a stroke of 100~450mm. It can lift or press down the traveling wheel assembly onto the upper surface of the main cable.

[0026] Rotary disk constraint frame ---- The rotary disk constraint frame is installed inside the platform frame through the upper longitudinal beam and the lower screw. Under the action of the screw, it can slide uniformly along the longitudinal direction of the frame as a whole.

[0027] The rotating assembly consists of a rotating disk and a rotating disk drive motor. The rotating disk is suspended on one side of the rotating disk constraint frame by 4 to 6 constraint pulleys. The outer surface of the rotating disk is equipped with ring gears. Under the action of the rotating disk drive motor through the gears, it can achieve uniform rotation around the main cable.

[0028] Belt reel – consists of a rotating shaft and a torque measuring instrument, with the belt reel fixed on a rotating disk.

[0029] The clamping mechanism consists of hydraulic jacks, steel structure jacks, and steel structure curved plates. Four sets of clamping mechanisms are symmetrically and horizontally installed on the inner sides of the front and rear gantry frames of the platform frame. Under the action of hydraulic jacks, the entire platform frame can be firmly clamped to the main cable.

[0030] Slide rails – I-beam slide rails are installed on the bottom inner side of the platform. The two ends of the slide rails are connected to the gantry frames at the front and rear of the platform frame, and the bottom of the slide rails is connected to the frame at the bottom of the platform frame. Trolleys that can slide along the I-beam slide rails are installed on the slide rails.

[0031] Trolley ---- The trolley is suspended on the upper surface of the slide rail. The load of the trolley is not less than 5T. The trolley can slide back and forth along the I-beam slide rail.

[0032] The sling is made of nylon or polypropylene and has a load capacity of not less than 3T. The sling straddles the upper surface of the main cable. Both ends of the sling are connected to the pulley by steel structure pins. The entire mobile platform wrapping machine can be suspended on the main cable by the sling through the height lifting mechanism in the front and rear gantry sections of the operating platform.

[0033] The longitudinal drive assembly of the rotating disk consists of a lead screw and a lead screw drive motor. Both the lead screw and the lead screw drive motor are installed on the bottom inner side of the movable steel structure platform frame. When the lead screw drive motor is started, the lead screw is rotated, thereby driving the rotating disk constraint frame to move forward at a uniform speed together with the rotating disk.

[0034] The platform moving traction assembly consists of a traction hoist and a traction wire rope. One end of the traction wire rope passes through the traction hoist and then through a steering pulley installed on the main cable about 20-30m in front of the mobile platform electric wrapping machine. The other end of the traction wire rope is then fixed to the column on the outside of the gantry in front of the platform frame. When the traction hoist is started, the entire mobile platform electric wrapping machine can be pulled forward at a constant speed by the traction of the traction wire rope.

[0035] The working principle of the mobile platform electric wrapping machine of this invention: A wrapping method based on the aforementioned mobile platform-type electric wrapping machine. Method 1 of wrapping work: S1. The walking wheel assembly is driven down to the upper surface of the workpiece by the height lifting mechanism. The entire movable platform electric wrapping machine is suspended and supported on the workpiece by the walking wheel assembly. At the same time, the clamping mechanism clamps the entire platform frame and the workpiece together. S2. Start the rotary drive unit, the rotary disk rotates, and at the same time start the rotary disk longitudinal drive assembly; S3. The rotating disk constraint frame moves at a constant speed along the longitudinal direction of the platform frame with the rotating disk, and the wrapped part is wrapped. S4. The rotary table stops working at the front end of the platform of the movable platform electric wrapping machine. The clamping mechanism releases the entire platform frame from the wrapped part. The platform frame is moved forward to the next working position by the platform moving traction assembly and then stops moving. The rotary table longitudinal drive assembly is started to rotate in the opposite direction, so that the rotary table constraint frame drives the rotary table back to the end position of the previous wrapping. Steps S1 to S3 are repeated. Method 2 for wrapping packages: SA, the walking wheel assembly is driven down to the upper surface of the workpiece by the height lifting mechanism. The entire mobile platform electric wrapping machine is suspended and supported by the walking wheel assembly. At the same time, the clamping mechanism releases the entire platform frame from the workpiece. SB, start the rotary drive unit, the rotary table rotates, and at the same time start the platform moving traction assembly; SC, the platform frame moves forward at a constant speed, and the wrapped part is wrapped.

[0036] This invention further discloses a working method for a mobile platform-type electric wrapping machine to overcome obstacles on the surface of the wrapped part, comprising the following steps: The working principle of the movable platform electric wrapping machine's front gantry spanning the cable clamp: Step 1: When a set of traveling wheels on the platform frame encounters an obstacle, the sling is straddled on the upper surface of the part being wound and close to the set of traveling wheels on the nearby obstacle. The two ends of the sling are connected to the trolley by pins. At this time, the sling can be securely connected to the entire part being wound. Step 2: A set of walking wheel assemblies near the obstacle on the platform frame is raised above the obstacle by the height lifting mechanism connected to it. At this time, the part of the movable platform electric wrapping machine near the obstacle is suspended and supported by the sling. The platform moving traction assembly is started, and the entire platform frame moves forward at a constant speed until the walking wheel assembly at the front end in the wrapping direction passes the obstacle. During the process of crossing the obstacle, the two ends of the sling slide along the slide rail through the trolley. Step 3: The method for the platform frame's rear walking wheel assembly to cross obstacles on the surface of the wrapped part is the same as in Steps 1 to 2.

[0037] It should be noted that before step three, the sling needs to be detached from the wrapped part, and after the sling is passed over the obstacle, it needs to be securely connected to the wrapped part again.
