Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a hoisting structure for building engineering. Background Technology

[0002] In the field of construction engineering, the hoisting of I-beams commonly employs manually operated clamp structures. This method is particularly prevalent in small to medium-sized projects and construction scenarios requiring high flexibility. Before lifting, operators need to manually check the clamp's tightness. However, manual inspection in existing technologies presents certain safety hazards: firstly, in the complex environment of high-altitude operations, limited visibility, workspace, and operator fatigue make it difficult for operators to accurately determine whether the clamps are fully locked.

[0003] On the other hand, the lack of an intuitive locking status indicator means that inspectors often need to repeatedly check at close range, which is not only inefficient but also makes it difficult to ensure the reliability of each inspection. This human-dependent inspection mechanism is prone to insecure clamping due to negligence or misjudgment, which can lead to slippage of the I-beam during hoisting, posing a serious safety risk to high-altitude operations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a hoisting structure for construction engineering, which uses a safety bar-type mechanical interlock and visual confirmation design to confirm the clamping state of the clamps, so as to solve the technical problems described in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A hoisting structure for construction engineering includes a hanger with lifting lugs. At least two sets of clamps are installed at intervals along the length of the hanger. Each clamp includes a clamp body A and a clamp body B. The clamp body B is rotatable and cooperates with the clamp body A to clamp an I-beam.

[0007] The outer surfaces of clamp body A and clamp body B are respectively fixed with sleeve A and sleeve B. A safety bar is movably inserted into sleeve B. When the safety bar is inserted from sleeve B into sleeve A, clamp body A and clamp body B can be connected as one unit.

[0008] Furthermore, the outer surface of the clamp body B is integrally formed with a support lug, and the support lug has an insertion hole on the side facing the sleeve A, and a limit hole is formed on the inner wall of the insertion hole.

[0009] The safety bar is provided with a limiting component, which cooperates with the limiting hole to restrict the movement of the safety bar when the safety bar is inserted into the insertion hole.

[0010] Furthermore, the outer surface of the bumper has a receiving cavity along its radial direction, and the limiting component includes a spring and a limiting block installed in the receiving cavity. The limiting block is fixedly connected to the spring and extends halfway out of the receiving cavity under the action of the spring.

[0011] The end of the limiting block that extends out of the receiving cavity has an inclined surface, and the inclined surface is located on the movement path of the bumper.

[0012] Furthermore, a strip-shaped clearance groove is provided through the outer surface of the sleeve A in the radial direction, the length of the clearance groove being the same as the length of the sleeve A, and a notch is provided on the end face of the sleeve B facing the sleeve A.

[0013] Furthermore, the hanger includes a frame body on which the lifting lugs are mounted and a mounting rod on which the clamps are mounted, the mounting rod being connected to the frame body via a flange.

[0014] Furthermore, the mounting rod includes two rods A and a rod B fixedly connected between the two rods A. The diameter of the rod B is smaller than the diameter of the rods A, and the length of the rod B is adapted to the length of the clamp.

[0015] Furthermore, the surface of the rod A is integrally formed with a protrusion, and the clamp A has a groove that engages with the protrusion to restrict the circumferential rotation of the clamp A.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The manual insertion of the safety bar in this utility model serves as a mandatory safety step before hoisting. Through a physical intervention mechanism (requiring active manipulation of the safety bar), it overcomes the shortcomings of traditional reliance on visual inspection, eliminating clamping failures due to human error and significantly improving operational safety. The visible installation status of the safety bar (inserted / not inserted) forms an intuitive visual confirmation mark, facilitating quick verification of clamping effectiveness by inspection personnel, thus meeting the visualization requirements of high-altitude operation safety management.

[0018] 2. This utility model mechanically interlocks clamp body A and clamp body B through the safety rod, forming a rigid connection structure, which completely eliminates the axial displacement and rotational freedom of the clamps and the mounting rod. Even under high-frequency vibration or sudden impact conditions, the I-beam can still maintain zero displacement clamping, completely eliminating the risk of slippage at heights.

[0019] Secondly, the separate design of sleeve A and sleeve B retains the flexible adjustment function of the clamp, while achieving rigid fixation through plug-in locking. Attached Figure Description

[0029] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0030] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Please see Figure 1 and Figure 2This utility model provides a technical solution: a hoisting structure for building engineering, including a hoist 1, the hoist 1 including a frame body 11 and at least two mounting rods 12, the mounting rods 12 are connected to the frame body 11 through flanges 13, and each mounting rod 12 is equipped with a clamp 3 for clamping I-beams, the frame body 11 has lifting lugs 2 for hoisting.

[0032] The mounting rod 12 includes two rods A121 with flanges 13 fixed at their ends, and a rod B122 fixedly connected between the two rods A121 by a threaded connection. The diameter of the rod B122 is smaller than the diameter of the rods A121, and the length of the rod B122 is adapted to the length of the clamp 3, so that the clamp 3 will not move relative to the axial direction along the length of the mounting rod 12 when it is installed on the rod B122.

[0033] Please see Figure 1 , Figure 3 , Figure 4 and Figure 6 The clamp 3 includes a clamp body A31 and a clamp body B32. The clamp body B32 is rotatable and engages with the clamp body A31 to clamp the I-beam. The surface of the rod A121 is integrally formed with a protrusion 4, and the clamp body A31 has a groove 5. The engagement of the protrusion 4 and the groove 5 restricts relative circumferential rotation between the clamp body A31 and the rod A121, ensuring that the clamp body A31 remains stationary after the clamp 3 is assembled onto the mounting rod 12. By driving the clamp body B32 to rotate relative to the mounting rod 12, the clamp 3 opens or closes to clamp the I-beam.

[0034] During actual clamping, the clamping parts of clamp body A31 and clamp body B32 extend to the connection between the flange and the web of the I-beam and abut against its surface for clamping. Alternatively, a manual lever or screw mechanism can be used to drive the jaws to close (such as bolt tightening or eccentric wheel pressing) to further ensure the effectiveness of clamping. The specific structure and application are already quite mature in the prior art and are not the focus of this application, so they will not be described in detail here.

[0035] Please see Figure 3 , Figure 4 and Figure 6 The outer surfaces of the clamp body A31 and the clamp body B32 are respectively fixed with sleeve A33 and sleeve B34. A safety rod 35 is movably inserted into the sleeve B34. When the safety rod 35 is inserted from the sleeve B34 into the sleeve A33, the clamp body A31 and the clamp body B32 can be connected as one unit to ensure the clamping position.

[0036] Secondly, since the clamp body A31 does not rotate relative to the mounting rod 12, when they are connected as one piece, the clamp 3 can stably maintain the clamping state. After the safety rod 35 is inserted, the clamp 3 and the mounting rod 12 have no axial displacement or rotational freedom. Even if subjected to vibration or impact, the I-beam remains fixed, eliminating the risk of slippage at high altitudes.

[0037] The axial insertion and removal operation of the safety rod 35 requires only a unidirectional movement, which is ergonomic, easy to complete quickly, and less prone to misoperation. Manually applying safety during hoisting by moving the safety rod 35 into place avoids the problem of hoisting personnel forgetting to check the clamping securely before lifting, thus preventing the I-beam from slipping during hoisting and ensuring safe operation.

[0038] Please see Figure 3 , Figure 5 and Figure 6 The clamp body B32 has an integrally formed lug 36 on its outer surface. The lug 36 has an insertion hole 37 on the side facing the sleeve A33. The inner wall of the insertion hole 37 has a limiting hole 38. The outer surface of the safety rod 35 has a receiving cavity 391 along its radial direction. The receiving cavity 391 is provided with a limiting component 39. The limiting component 39 includes a spring 392 and a limiting block 393 installed in the receiving cavity 391. The limiting block 393 is fixedly connected to the spring 392 and partially extends out of the receiving cavity 391 under the action of the spring 392.

[0039] When the safety bar 35 is inserted into the sleeve A33 by the sleeve B34, the safety bar 35 is pushed further, causing the end of the safety bar 35 to be inserted into the insertion hole 37 of the lug 36. When the limiting block 393 is aligned with the limiting hole 38, the limiting block 393 extends into the limiting hole 38 under the action of the spring 392, and cooperates with the limiting hole 38 to restrict the movement of the safety bar 35, ensuring that the safety bar 35 continuously and stably connects the clamp body A31 and the clamp body B32 into one unit.

[0040] Please see Figure 5 The end of the limiting block 393 extending out of the receiving cavity 391 has an inclined surface 394. The inclined surface 394 is located on the movement path of the safety rod 35. The inclined surface 394 facilitates the insertion of the safety rod 35 into the insertion hole 37. The support lug 36 presses the limiting block 393 through the inclined surface 394, pressing the limiting block 393 into the receiving cavity 391, ensuring that the end of the safety rod 35 is smoothly inserted into the insertion hole 37. At the same time, it also facilitates the smooth withdrawal of the safety rod 35 under the action of external force, releasing the clamping state.

[0041] Please see Figure 3 and Figure 4 The outer surface of the sleeve A33 is provided with a strip-shaped clearance groove 331 extending through it in the radial direction. The length of the clearance groove 331 is the same as the length of the sleeve A33. The end face of the sleeve B34 facing the sleeve A33 is provided with a notch 341. When the safety rod 35 is pulled outward to release the clamping state, the clearance groove 331 avoids the movement of the limiting block 393. When the limiting block 393 moves into the notch 341 and abuts against the end wall of the notch 341, the end of the safety rod 35 is completely separated from the sleeve A33 and located in the sleeve B34. At this time, the clamp body B32 can be rotated to release the clamping state of the clamp 3.

[0042] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
