Description

[0001] The embodiments of the present disclosure belong to the field of hoisting technology, and particularly relate to a hoisting protection device for a steel structure assembly beam. Background Art

[0002] With the rapid progress of the times, steel structure factories are also developing rapidly. Traditional steel beams are equipped with lifting lugs for hoisting.

BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 This is a schematic structural diagram of a lifting protection device for a steel structure assembly beam according to an embodiment of the present disclosure;

[0019] Figure 2 This is a side view of a third connecting plate according to another embodiment of the present disclosure. DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] like Figure 1 and Figure 2As shown, a lifting protection device 100 for a steel structure assembly beam is shown. The lifting protection device 100 includes a connecting mold 110 and a clamping assembly 120. The connecting mold 110 includes a first connecting plate 111, a second connecting plate 112, and a third connecting plate 113. The first connecting plate 111 and the second connecting plate 112 are respectively connected to the same side of the opposite ends of the third connecting plate 113 to form a groove structure clamped on the wing plate of the steel structure assembly beam. The first connecting plate 111 is provided with at least one connecting through-hole (not marked in the figure), which is used to pass through the corresponding clamping assembly 120. The steel structure assembly beam can be clamped and fixed by the clamping assembly 120 and the second connecting plate 112. The third connecting plate 113 is provided with a plurality of grooves 114 distributed side by side on the side facing away from the first connecting plate 111 and the second connecting plate 112. The steel wire rope is wound around the connecting mold 110 through each of the grooves 114 for lifting.

[0022] Specifically, if Figure 1 and Figure 2 As shown, the groove structure formed by the first connecting plate 111, the second connecting plate 112 and the third connecting plate 113 can be clamped on the wing plate of the steel structure assembly beam, and its position on the wing plate of the steel structure assembly beam can be adjusted arbitrarily. When the connecting mold 110 is clamped at the corresponding position on the wing plate of the steel structure assembly beam, the clamping assembly 120 passes through the corresponding connecting through hole on the first connecting plate 111, and the end of the clamping assembly 120 close to the second connecting plate 112 works together with the inner surface of the second connecting plate 112 to clamp and fix the wing plate of the steel structure assembly beam, thereby fixing the steel structure assembly beam. The central part of the steel wire rope is embedded in the grooves 114 on the outer surface of the third connecting plate 113, and the two ends of the steel wire rope are hoisted around the connecting mold 110. It is not difficult to understand that the number of connecting through holes corresponds to the number of clamping assemblies and can be set according to actual needs.

[0023] As a specific example, Figure 1 and Figure 2 As shown, the third connecting plate 113 is configured as an arc-shaped structure, which can further reduce the wear of the steel wire rope when it contacts the edge portion of the third connecting plate 113.

[0024] Furthermore, the plurality of grooves 114 are evenly spaced on the third connecting plate 113. The evenly spaced grooves can evenly accommodate the steel wire ropes, so that the steel wire ropes are evenly distributed on the outer surface of the third connecting plate, further ensuring stability during lifting.

[0025] In the lifting protection device for the steel structure assembly beam of the embodiment disclosed in the present invention, the connection mold can adjust the position at will, quickly find the force point for lifting the steel structure assembly beam, and avoid tilting caused by uneven force during lifting. The connection mold and the clamping assembly are fixed on the wing plate of the steel structure assembly beam to prevent the steel structure assembly beam from slipping during lifting. The groove plays a role in limiting and protecting the wire rope during lifting, which can prevent the wire rope from slipping, prevent the wire rope from directly contacting the wing plate of the assembled steel beam, reduce the wear of the wire rope and the edge of the steel beam, and ensure the smooth progress of the lifting operation. The lifting protection device of this embodiment has a simple structure and is labor-saving to operate. It does not perform structural operations on the steel beam, can ensure the strength and structural stability of the steel beam, is flexible to install and dismantle, can be used repeatedly, and reduces material waste.

[0026] For example, Figure 1 As shown, a buffer layer 130 is fixedly provided on the inner surface of the groove structure formed by the first connecting plate 111 , the second connecting plate 112 and the third connecting plate 113 .

[0027] Specifically, if Figure 1 As shown, a buffer layer 130 is provided on the inner surface of the connection mold 110. The provision of the buffer layer 130 can prevent the steel structure assembly beam from being damaged by the rigid contact with the connection mold 110.

[0028] Furthermore, the buffer layer 130 is a wool felt layer with a thickness of 5 mm to 10 mm.

[0029] Specifically, the buffer layer 130 can be set as a wool felt layer, and a self-adhesive adhesive is applied to the inner side of the wool felt layer to fix it on the inner surface of the connecting mold 110. For example, the thickness of the wool felt layer can be set in the range of 5mm to 10mm, such as 7mm, 8.5mm, etc.

[0030] For example, Figure 1 As shown, the clamping assembly 120 includes a bolt 121 and a shoe 122. The bolt 121 is threadedly connected to the first connecting plate 111 through the corresponding connecting through hole, and the shoe 122 is provided at one end of the bolt 121 facing the second connecting plate 112.

[0031] Specifically, if Figure 1 As shown, bolt 121 is threadedly connected to the first connecting plate 111 through a corresponding connecting through-hole. Foot 122 is attached to the end of bolt 121 facing the second connecting plate 112. The provision of foot 122 increases the contact area between bolt 121 and the flange of the steel structure assembly beam, increasing friction and overall stability. The bolt connection to the connection mold also further facilitates rapid installation of the steel structure assembly beam. As a specific example, bolt 121 can be configured as an M18 high-strength trapezoidal bolt.

[0032] Furthermore, the shoe foot 122 is a truncated cone structure. The first bottom surface of the truncated cone structure is fixed to the end of the bolt 121 facing the second connecting plate 112, and the second bottom surface of the truncated cone structure is used to contact the flange of the steel structure assembly beam. The first bottom surface is smaller than the second bottom surface.

[0033] Specifically, if Figure 1 As shown, the first bottom surface of the frustum structure is the same size as the bottom of the bolt 121, and the first bottom surface of the frustum structure is fixed to the bottom of the bolt 121. The second bottom surface of the frustum structure is larger than the first bottom surface of the frustum structure. When the second bottom surface of the frustum structure contacts and fixes the flange of the steel structure assembly beam, it can effectively increase the contact area, thereby making the whole structure more stable.

[0034] For example, the clamping assembly 120 further includes a mounting ring 123. The mounting ring 123 is disposed at one end of the bolt 121 away from the second connecting plate 112. Providing the mounting ring 123 on top of the bolt 121 makes manual installation faster and more convenient.

[0035] The hoisting protection device for steel structure assembly beams disclosed in the embodiments of the present invention can save material and labor costs for subsequent steel beam lifting lugs, avoid wear between the wire rope and the flange at the bottom of the steel beam, reduce wire rope material loss, and ensure the safety of the hoisting work. It increases the hoisting speed of assembled steel beams, has a low deadweight, is easy to transport, is reusable, is environmentally friendly, and is inexpensive, making it suitable for mass production. Furthermore, its use does not affect the construction of other types of work and does not involve secondary finishing work. The device has a simple structure, is easy to install, and is quick to dismantle.

[0036] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present disclosure, and the present disclosure is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present disclosure, and such modifications and improvements are also considered to be within the scope of protection of the present disclosure.
