Description

Technical Field

[0001] The invention relates to the technical field of safe transportation of I-beams, in particular to an I-beam transportation sleeve. Background Art

[0002] In the field of construction, I-beams are a commonly used building material, and their transportation and loading and unloading operations are important links in the construction process. At present, the transportation methods of I-beams in existing technologies mainly rely on manual operation or simple lifting equipment, which poses significant safety hazards and efficiency problems.

[0003] Traditional methods often use ropes or hooks to directly tie I-beams for lifting. Although this method is easy to operate, it has obvious defects: the stability of the rope tying is completely dependent on the accuracy of manual operation. During the high-altitude lifting process, it is very easy to become loose or fall off due to factors such as vibration and wind, causing the I-beam to fall out of control, posing a serious safety threat to construction workers and surrounding facilities. Especially in high-rise building construction, workers are often forced to throw I-beams directly from heights due to the lack of reliable transportation tools. Such operations can easily cause the I-beams to flip or collide in the air, resulting in structural damage or safety accidents. Although special clamps are used to fix the ends of the I-beams for lifting in some scenarios, which improves safety compared to rope tying, existing clamps generally have design flaws: On the one hand, the clamping structure of the clamp is mostly a rigid connection, which is difficult to adapt to the changes in the cross-sectional dimensions of I-beams of different specifications, resulting in loose fixation or uneven distribution of clamping force, and the I-beams are prone to tilting and shaking during transportation; on the other hand, the opening and closing operations of the clamps rely on complex mechanical structures or manual assistance, which increases loading and unloading time and construction difficulty, and cannot meet the needs of efficient construction. In addition, existing transportation tools generally lack guidance and buffering designs. I-beams are prone to rigid collision with transportation equipment during loading or unloading, causing damage to the material surface. At the same time, there are no night warning signs, and there is a high operational risk in low-visibility environments.

[0004] To sum up, the existing I-beam transportation technology has shortcomings in terms of safety, stability, versatility and operational efficiency. There is an urgent need for a special device that can achieve smooth loading and unloading, reliable fixation and safe transportation of I-beams to solve the safety hazards and low efficiency problems caused by problems such as loose fixation, lack of guidance, and insufficient buffering in the existing technology. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides an I-beam transport sleeve, which solves the safety hazards and low efficiency problems caused by the loose fixation of the prior I-beam transport technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an I-beam transport casing, comprising a main casing, the upper surface of which is fixedly connected to a lifting ring, the bottom end of which is internally rotatably connected to a guide assembly, and the inner top wall of the main casing is fixedly connected to a locking mechanism.

[0007] By adopting the above technical solution, the main casing serves as the core bearing structure, and its long cylindrical design completely wraps the I-beam, avoiding deformation or falling due to external force collision during transportation, and solving the falling risk of traditional rope binding or exposed lifting. The lifting ring provides a rigid lifting fulcrum to ensure uniform force transmission during lifting, avoiding tilting or slipping caused by uneven force in traditional rope binding, and simplifying the lifting operation process. The guide assembly guides the I-beam to be inserted accurately through rolling friction, reducing manual alignment time, preventing collision damage between the I-beam and the casing mouth, and improving loading and unloading efficiency and safety. The locking mechanism replaces manual fixation with mechanical clamping, adaptively clamps I-beams of different specifications, resists vibration and wind interference during transportation, and eliminates the risk of loosening.

[0008] Preferably, the guide assembly includes a guide wheel, the outer wall of the guide wheel is rotatably connected to the bottom end of the main sleeve, the interior of the guide wheel is fixedly connected to a fixing column, and the outer wall of the fixing column is rotatably connected to the bottom end.

[0009] Preferably, the locking mechanism includes a support plate, a claw assembly 1, a claw assembly 2 and a drive assembly. The claw assembly 1 and the claw assembly 2 have the same structure, and the upper surface of the support plate is fixedly connected to the inner top wall of the main sleeve.

[0010] Preferably, the claw assembly 1 includes a connecting rod 1, the upper inner side of the connecting rod 1 is rotatably connected to the outer wall of the support plate, the lower inner side of the connecting rod 1 is fixedly connected to a support block, the lower outer wall of the support block is fixedly connected to a clamping rod, the upper outer wall of the support block is rotatably connected to a connecting rod 2, and the inner wall of the connecting rod 2 is rotatably connected to the outer wall of the support plate.

[0011] Preferably, the driving assembly includes an electric push rod, the top end of the electric push rod is fixedly connected to the lower surface of the support plate, the output end of the electric push rod is connected to a mounting block, one side outer wall of the mounting block is rotatably connected to a rotating rod 1, the inner wall of the rotating rod 1 is rotatably connected to a fixed block 1, the other side outer wall of the mounting block is rotatably connected to a rotating rod 2, and the inner wall of the rotating rod 2 is fixedly connected to a fixed block 2.

[0012] Preferably, the guide wheels are a pair that are symmetrically arranged, and their surfaces are provided with anti-slip patterns.

[0013] Preferably, an anti-slip rubber pad is provided on the inner side of the clamping rod.

[0014] Preferably, the outer wall of the main sleeve is provided with a reflective marking layer, and the inner wall of the main sleeve is provided with a buffer layer.

[0015] Preferably, the outer wall of the second fixing block is fixedly connected to the lower outer wall of the second claw assembly, and the outer wall of the first fixing block is fixedly connected to the outer wall of the second connecting rod.

[0016] Preferably, a method for using an I-beam transport casing comprises the following steps: S1. Hoist the main casing to the top of the I-beam to be transported using the lifting ring, aligning the I-beam with the opening of the main casing; S2. Use the rotation of the guide wheel in the guide assembly to guide the I-beam to smoothly enter the main sleeve, and contact the locking mechanism on both sides of the I-beam; S3. Start the electric push rod in the drive assembly, which drives the rotating rod 1 and the rotating rod 2 to rotate through the mounting block, and then pushes the fixed block 1 and the fixed block 2, so that the clamping claw assembly 1 and the clamping claw assembly 2 clamp the I-beam inward, and use the anti-slip rubber pad to enhance the clamping stability; S4. After locking is completed, the main casing with the I-beam is lifted to the designated location through the lifting ring. During transportation, the buffer layer on the inner wall of the main casing reduces the shaking of the I-beam, and the reflective marking layer on the outer wall improves transportation safety. S5. After arriving at the destination, control the electric push rod to move in the reverse direction, so that the clamping rod releases the I-beam, and then lifts the main casing away to complete the unloading.

[0017] The present invention provides an I-beam transport casing, which has the following beneficial effects: 1. The present invention provides a locking mechanism inside the main sleeve to clamp and fix the I-beam, thereby significantly improving the safety of I-beam transportation, reducing safety accidents caused by I-beam falling, and ensuring the personal safety of on-site workers.

[0018] 2. The guide assembly arranged inside the bottom end of the main casing of the present invention converts the sliding friction during the insertion of the I-beam into rolling friction through the symmetrically arranged guide wheels with anti-slip patterns on the surface, significantly reducing the insertion resistance and the wear of the I-beam and the casing. The rotational guiding effect of the guide wheels can accurately guide the I-beam to align with the opening of the main casing, ensuring its smooth entry into the interior of the casing, improving the loading and unloading efficiency while avoiding the errors and safety risks of manual alignment.

[0019] 3. The buffer layer on the inner wall of the main casing is made of elastic material, which absorbs vibration energy during transportation, reduces rigid collisions between the I-beam and the casing, and prevents structural damage caused by bumps. The reflective marking layer on the outer wall significantly improves the casing's visibility at night or in low-visibility environments. Combined with the modular design of the guide wheels and locking mechanism, the casing can adapt to I-beams of different specifications, providing strong versatility and reducing the adaptation cost of construction equipment.

[0022] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see the attached Figure 1 -Attached Figure 3 An embodiment of the present invention provides an I-beam transport casing, comprising a main casing 1, a lifting ring 2 being fixedly connected to the upper surface of the main casing 1, a guide assembly 3 being rotatably connected to the inside of the bottom end of the main casing 1, and a locking mechanism 4 being fixedly connected to the inner top wall of the main casing 1.

[0024] Specifically, first, the lifting ring 2 is lifted by a crane, and the lifting ring 2 will drive the main sleeve 1 to rise, and the I-beam is pushed into the interior of the main sleeve 1 through the guide assembly 3, and then the I-beam is fixed by starting the locking mechanism 4. After the main sleeve 1 with the I-beam is lifted to the specified position through the lifting ring 2, the locking mechanism 4 is started to release the main sleeve 1, and finally the material is unloaded. The lifting ring 2 at the top of the main sleeve 1 is connected to the external lifting equipment, and the main sleeve 1 is lifted through the rigid connection point of the lifting ring 2. The main sleeve 1 is a long cylindrical structure with a space for accommodating the I-beam inside. The guide assembly 3 is used to guide the I-beam to enter the main sleeve 1 smoothly, thereby significantly improving the safety of the I-beam transportation, reducing the safety accidents caused by the falling of the I-beam, and ensuring the personal safety of on-site workers.

[0025] Please see the attached Figure 3 -Attached Figure 5 The guide assembly 3 includes a guide wheel 31, the outer wall of the guide wheel 31 is rotatably connected to the bottom end of the main sleeve 1, and the interior of the guide wheel 31 is fixedly connected to a fixed column 32, and the outer wall of the fixed column 32 is rotatably connected to the bottom end.

[0026] Specifically, during the process of inserting the I-beam into the main sleeve 1, there is rolling friction between the guide wheel 31 and the flange of the I-beam. Compared with sliding friction, the resistance of rolling friction is much smaller, so that the contact mode between the I-beam and the main sleeve 1 is changed from direct sliding contact to rolling contact. The resistance encountered during the insertion of the I-beam is greatly reduced, reducing the wear on the I-beam and the main sleeve 1, and at the same time reducing the force required for the lifting equipment, thereby improving the efficiency and convenience of the operation. At the same time, through the guidance and positioning of the guide wheel 31, the I-beam can enter the main sleeve 1 more accurately, greatly improving the success rate of installation.

[0027] Please see the attached Figure 6 The locking mechanism 4 includes a support plate 41, a claw assembly 5, a claw assembly 2 6 and a driving assembly 7. The structures of the claw assembly 1 5 and the claw assembly 2 6 are the same. The upper surface of the support plate 41 is fixedly connected to the inner top wall of the main sleeve 1.

[0028] Specifically, drive assembly 7 is the power source for locking mechanism 4. Its primary function is to provide driving force for the movement of jaw assembly 1 5 and jaw assembly 2 6, thereby enabling the opening and clamping of jaw assembly 1 5 and jaw assembly 2 6. Support plate 41 allows for a certain degree of flexibility during the movement of jaw assembly 2 6 and jaw assembly 1 5, allowing for appropriate adjustment based on the position and size of the I-beam. Furthermore, support plate 41 ensures the stability of the movement of jaw assembly 2 6, enabling accurate clamping and release.

[0029] Please see the attached Figure 8 The clamping claw assembly 5 includes a connecting rod 1 51, the upper inner side of the connecting rod 1 51 is rotatably connected to the outer wall of the support plate 41, the lower inner side of the connecting rod 1 51 is fixedly connected to the support block 52, the lower outer wall of the support block 52 is fixedly connected to the clamping rod 54, the upper outer wall of the support block 52 is rotatably connected to the connecting rod 2 53, and the inner wall of the connecting rod 2 53 is rotatably connected to the outer wall of the support plate 41.

[0030] Specifically, when the I-beam needs to be locked, the driving assembly 7 starts to operate, and the power generated by the driving assembly 7 will push the connecting rod 1 51 and the connecting rod 2 53 to rotate around them and the support plate 41, thereby driving 54 to clamp the I-beam.

[0031] When the I-beam needs to be loosened, the driving assembly 7 operates in the reverse direction, applying reverse power to cause the connecting rod 1 51 and the connecting rod 2 53 to rotate in opposite directions around the support plate 41. This in turn drives the support block 52 to move away from the I-beam, causing the clamping rod 54 to loosen the I-beam, making it easier to remove the I-beam from the main sleeve 1.

[0032] Please see the attached Figure 7 and attached Figure 8 The driving assembly 7 includes an electric push rod 71, the top of the electric push rod 71 is fixedly connected to the lower surface of the support plate 41, and the output end of the electric push rod 71 is connected to a mounting block 72. The outer wall of one side of the mounting block 72 is rotatably connected to a rotating rod 1 73, and the inner wall of the rotating rod 1 73 is rotatably connected to a fixed block 1 74. The outer wall of the other side of the mounting block 72 is rotatably connected to a rotating rod 2 75, and the inner wall of the rotating rod 2 75 is fixedly connected to a fixed block 2 76; the outer wall of the fixed block 2 76 is fixedly connected to the lower outer wall of the claw assembly 2 6, and the outer wall of the fixed block 1 74 is fixedly connected to the outer wall of the connecting rod 2 53.

[0033] Specifically, the top end of the electric push rod 71 is firmly fixed on the lower surface of the support plate 41, providing a support point for subsequent actions. When the I-beam needs to be locked or released, the electric push rod 71 starts to operate, and the output end of the electric push rod 71 is connected to the mounting block 72. As the electric push rod 71 extends and retracts, the mounting block 72 also moves accordingly.

[0034] The mounting block 72 is rotatably connected to a first rotating rod 73 and a second rotating rod 75 on either side. When the mounting block 72 moves, the first rotating rod 73 and the second rotating rod 75 begin to rotate around the mounting block 72. The rotation of the first rotating rod 73 and the second rotating rod 75 then transmits force to the second connecting rod 53 and the second claw assembly 6 through the first fixing block 74 and the second fixing block 76.

[0035] When the electric push rod 71 extends, the mounting block 72 moves downward, driving the rotating rod 1 73 and the rotating rod 2 75 to rotate outward. This causes the fixing block 1 74 and the fixing block 2 76 to push the connecting rod 2 53 and the clamping claw assembly 2 6 toward the I-beam, ultimately achieving the clamping of the I-beam by the clamping rod 54, completing the locking operation.

[0036] When the electric push rod 71 contracts, the mounting block 72 moves upward, and the rotating rod 1 73 and the rotating rod 2 75 rotate inward, driving the fixed block 1 74 and the fixed block 2 76 to move in the opposite direction, so that the connecting rod 2 53 and the claw assembly 2 6 release the I-beam, realizing the release operation.

[0037] The driving assembly 7 efficiently completes the locking and releasing of the I-beam through the coordinated operation of the electric push rod 71, the mounting block 72, the rotating rod 1 73, the rotating rod 2 75, the fixed block 1 74 and the fixed block 2 76, thereby providing a strong guarantee for the safe transportation of the I-beam.

[0038] Please see the attached Figure 1 -Attached Figure 3 The outer wall of the main sleeve 1 is provided with a reflective identification layer, the inner side of the clamping rod 54 is provided with a non-slip rubber pad, and the inner wall of the main sleeve 1 is provided with a buffer layer.

[0039] Specifically, at night or in low-visibility environments, the reflective identification layer allows lifting equipment operators, ground staff and surrounding vehicles to identify the location of the casing in advance, avoiding collisions and scratches caused by blind spots. It is especially suitable for complex work scenarios such as construction sites and ports.

[0040] The rough surface of the rubber pad forms an engagement with the metal surface of the I-beam, effectively preventing the axial sliding of the I-beam caused by vibration and tilt during transportation, and ensuring the long-term stability of the clamping force of the locking mechanism.

[0041] The buffer layer is made of elastic materials such as EVA foam and rubber sheets, covering the area where the inner wall of the main casing contacts the I-beam flange. It is used to absorb vibration energy during transportation and reduce rigid collisions.

[0042] A method for using an I-beam transport casing comprises the following steps: S1. Hoist the main casing 1 above the I-beam to be transported using the lifting ring 2, aligning the I-beam with the opening of the main casing 1; S2. Using the rotation of the guide wheel 31 in the guide assembly 3, the I-beam is guided to smoothly enter the interior of the main sleeve 1, and both sides of the I-beam contact the locking mechanism 4; S3. Start the electric push rod 71 in the drive assembly 7, which drives the rotating rod 1 73 and the rotating rod 2 75 to rotate through the mounting block 72, and then pushes the fixing block 1 74 and the fixing block 2 76, so that the clamping claw assembly 1 5 and the clamping claw assembly 2 6 clamp the I-beam inward, and use the anti-slip rubber pad to enhance the clamping stability; S4. After locking is completed, the main casing 1 with the I-beam is lifted to the designated location through the lifting ring 2. During transportation, the buffer layer on the inner wall of the main casing 1 reduces the shaking of the I-beam, and the reflective marking layer on the outer wall improves transportation safety; S5. After arriving at the destination, the electric push rod 71 is controlled to move in the reverse direction, so that the clamping rod 54 releases the I-beam, and then the main sleeve 1 is lifted off to complete the unloading.

[0043] Specifically, first, with the help of external lifting equipment such as a crane connected to the lifting ring 2, relying on the stable connection between the lifting ring 2 and the upper surface of the main sleeve 1, the main sleeve 1 is accurately lifted to the top of the I-beam to be transported, and the lifting ring 2 is used as a force transfer point to evenly apply the pulling force of the lifting equipment to the main sleeve 1 to achieve smooth lifting.

[0044] After the I-beam is aligned with the opening of the main casing 1, the main casing 1 is slowly lowered or the I-beam is lifted so that the flanges of the I-beam contact the guide wheels 31 in the guide assembly 3. When pressure is applied to the I-beam, the guide wheels 31 begin to rotate around the fixed columns 32. Because the surface of the guide wheels 31 is provided with anti-slip grooves, the friction between the guide wheels 31 and the flanges of the I-beam is increased, allowing the guide wheels 31 to better guide the movement direction of the I-beam. Under the action of the rotation of the guide wheels 31, the I-beam is gradually guided to the central axis position of the main casing 1, thereby smoothly entering the interior of the main casing 1.

[0045] The operator activates the electric push rod 71 in the drive assembly 7. Once activated, its output pushes the mounting block 72 downward. One outer wall of the mounting block 72 pivots to connect to rotating rod 1 73, while the other outer wall pivots to connect to rotating rod 2 75. Rotating rods 1 73 and 2 75 begin to rotate around their connection points with the mounting block 72. The inner wall of rotating rod 1 73 pivots to connect to fixed block 1 74, while the inner wall of rotating rod 2 75 is fixedly connected to fixed block 2 76. The rotation of the rotating rods pushes fixed blocks 1 74 and 2 76 inward, respectively. The outer wall of fixed block 1 74 is fixedly connected to the outer wall of connecting rod 2 53, while the outer wall of fixed block 2 76 is fixedly connected to the lower outer wall of jaw assembly 2 6. Therefore, the movement of the fixed blocks drives jaw assemblies 1 5 and 2 6 to rotate inward, ultimately securing the I-beam through jaw assemblies 1 5 and 2 6.

[0046] After locking the I-beam, the lifting equipment is connected again via the lifting ring 2, and the main sleeve 1 with the I-beam sleeve is lifted to the designated transportation destination. During transportation, if the main sleeve 1 shakes due to factors such as bumps and vibrations during transportation, the buffer layer can absorb and disperse energy through its own elastic deformation, reducing the rigid collision between the I-beam and the inner wall of the main sleeve 1, thereby reducing the shaking amplitude of the I-beam and protecting the I-beam and the main sleeve 1 from damage.

[0047] When the main sleeve 1, encased in the I-beam, reaches its designated destination, the operator controls the electric push rod 71 to reverse its motion. The reverse contraction of the push rod 71 drives the mounting block 72 upward, causing the first and second rotating rods 73 and 75 to rotate in opposite directions about their connection points with the mounting block 72. The reverse rotation of the rotating rods pulls the first and second fixed blocks 74 and 76 outward, respectively, driving the first and second clamping assemblies 5 and 6 to rotate outward, releasing the I-beam and ultimately lifting the main sleeve 1 off the I-beam.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
