Description

Technical Field

[0001] This utility model relates to the field of transportation and fixing technology, and in particular to a device for preventing displacement of large items during transportation. Background Technology

[0002] As industrial equipment develops towards larger scale and integration, the dimensions of large cylindrical components are constantly increasing, with diameters and lengths continuously expanding, posing a severe challenge to transportation safety. These cylindrical components typically feature thick walls and long axial dimensions. Some components made of special materials also exhibit weak impact resistance and are difficult to repair after deformation. Therefore, stability control and structural protection during transportation have become core pain points of concern in the industry. Currently, the road or rail transport of large cylindrical components mostly uses specialized flatbed trucks as the carrying carrier, and the fixing methods primarily rely on traditional rope binding, wooden wedge filling, or simple steel brackets for limitation. The core design goal of these fixing methods is to prevent lateral or longitudinal displacement of the cylindrical components during transportation starts, stops, turns, or road bumps.

[0003] However, large cylindrical components can weigh tens to hundreds of tons. During transportation, the weight is mainly borne by the bottom contact area, which easily leads to central sinking and end-end compression deformation, resulting in decreased flatness of the inner and outer walls or micro-cracks. Such deformation not only affects installation accuracy and sealing performance but may also damage the internal protective structure and reduce service life. Under high-pressure conditions, hidden deformation during transportation can become a hidden danger for safety accidents such as leakage and explosion. Therefore, this application aims to solve the problem of central sinking and end-end compression deformation caused by the weight of large cylindrical components during transportation, which leads to damage to sealing performance and protective layers and causes high-pressure leakage risks. A displacement prevention and fixing device for large-item transportation is proposed. Utility Model Content

[0004] To overcome the problem that during the transportation of large cylindrical components, insufficient weight and support often lead to central sinking and end-point deformation, which in turn reduces installation sealing and damages the inner protective layer, especially under high pressure, it is necessary to address this issue.

[0005] The technical solution of this utility model is as follows: a large-item transportation anti-displacement fixing device, including a transportation seat, a side stop connected to the transportation seat, and a connecting plate, the connecting plate being fixedly connected to the side stop, a driving component being connected to the connecting plate, a rotating shaft being connected to the output shaft of the driving component, an inner support component being connected to the rotating shaft, and the supporting end of the inner support component contacting the inner wall of the cylindrical part.

[0006] Preferably, the inner support assembly includes a coupling sleeve, the coupling sleeve closest to the rotating shaft is fixedly connected to the rotating shaft, a plurality of coupling sleeves are provided, and two adjacent coupling sleeves are connected by a combination shaft, and a fixing seat is fitted on the outer surface of the coupling sleeve.

[0007] Preferably, the inner support assembly further includes a first electric push rod, which is connected to the upper and lower ends of the fixed base. A connecting rod is connected to the telescopic end of the first electric push rod, and a first guide frame is connected to the fixed base. The first guide frame is slidably connected to the connecting rod.

[0008] Preferably, a second electric push rod is connected to both sides of the connecting rod, and an inner support head is connected to the telescopic end of the second electric push rod. The inner support head is the support end of the inner support assembly, and a second guide frame is connected to the first guide frame.

[0013] The beneficial effects of this utility model are: 1.

At the same time, it greatly enhances the overall rigidity, avoids instability and vibration caused by its own weight and inertia, and thus protects the existing inner wall coating, precision interfaces and geometric accuracy of the cylinder to the greatest extent, ensuring that the product arrives at its destination in good condition, and allowing for safer and more efficient stacking and transportation, saving space and cost. 2. When transporting large cylindrical components, the third electric push rod can be retracted to separate the coupling seat from the rotating shaft. The hydraulic push rod can be retracted to move the coupling seat to the surface of the transport seat, so that the operator can use a crane to lift the large cylindrical component and place it on the side stop, thereby improving the ease of use of the entire device to a certain extent. 3. By increasing the number of combined shafts and connecting sleeves, the number of internal support heads can be increased, thus enabling the device to adapt to large cylindrical components of different lengths. In addition, after increasing the number of combined shafts, the distance between the adjusting head and the side stop can also be adjusted synchronously by adjusting the telescopic seat and telescopic frame, thereby achieving adaptability adjustment for large cylindrical components of different lengths.

[0018] Among them, the drive component 302 is set as a combination of variable frequency speed control worm gear reducer motor and frequency converter. The variable frequency speed control motor is generally selected as a gear motor of model S97 DH90M4 BE5 and is used in conjunction with it. The frequency converter is generally selected as a frequency converter of model MOVITRAC 31B015-5A3-4-00. A positioning head 304 is fitted on the outer surface of the rotating shaft 303, and the positioning head 304 is connected to the connecting plate 301. The rotating shaft 303 is connected to the output shaft of the variable frequency speed regulating worm gear reducer motor. This embodiment is only applicable to large cylindrical components. When the device is in use, the large cylindrical component is placed on the side support 305, allowing the inner support assembly to extend into the interior of the large cylindrical component. The inner support assembly provides internal support for the large cylindrical component, effectively resisting external compression and internal stress during transportation. This fundamentally prevents the cylindrical component from undergoing elliptical deformation, crushing, or local denting during hoisting, stacking, and road bumps. At the same time, it greatly enhances the overall rigidity, avoiding instability and vibration caused by its own weight and inertia. This maximizes the protection of the existing inner wall coating, precision interfaces, and geometric accuracy of the cylindrical component, ensuring that the product arrives at its destination intact. It also allows for safer and more efficient stacking and transportation, saving space and costs.

[0024] When transporting large cylindrical components, the third electric push rod 502 can be retracted to separate the coupling seat 501 from the rotating shaft 303. The hydraulic push rod 507 can be retracted to move the coupling seat 501 to the surface of the transport seat 1, so that the operator can use a crane to lift the large cylindrical component and place it on the side stop seat 305, thereby improving the ease of use of the entire device to a certain extent.

[0027] The number of inner support heads 408 is increased by increasing the number of combined shafts 409 and connecting sleeves 401, so that the device can be adapted to large cylindrical parts of different lengths. After the combined shafts 409 are increased, the distance between the adjusting head 203 and the side stop 305 can also be adjusted synchronously by adjusting the telescopic seat 201 and the telescopic frame 202, thereby achieving adaptability adjustment for large cylindrical parts of different lengths.
