Description

Technical Field

[0001] The present application relates to the technical field of steel cable tensioning, and in particular to an air film steel cable tensioning clamp. Background Art

[0002] The air membrane structure uses an air membrane as the outer shell, and inflates the air membrane to form a positive pressure, thereby supporting the main body of the membrane. In order to enhance the stability of the air membrane, it is necessary to set an outer cover steel cable net on the outside of the air membrane. The outer cover steel cable net includes multiple steel cables, which span the surface of the air membrane and are connected to anchor points on the ground at both ends. Multiple steel cables are arranged at different angles to form a staggered outer cover steel cable net. The steel cable usually includes a steel wire rope and a PE layer wrapped around the surface of the steel wire rope. The end of the steel cable is bent to form a heart-shaped cable head, and the bent end of the steel cable and the main body are connected by an aluminum sleeve to tighten it.

[0003] During the actual installation of the steel cable, some of the steel cables need to be installed after the air film is inflated, or the steel cables need to be replaced during the construction process; during the installation or replacement of the steel cable, the cable head needs to be stretched to the anchor point on the ground with tools, and then the cable head and the anchor point are connected. During the tensioning process, the PE layer is easily damaged by force or friction, and the aluminum sleeve is also easily deformed due to force. Utility Model Content

[0036] Example

[0037] The present embodiment discloses an air film steel cable tensioning clamp. It should be noted that the air film steel cable 100 includes a steel wire rope and a PE layer wrapping the steel wire rope. The end of the steel cable 100 is bent to form a heart-shaped cable head 200, and the bent end of the steel cable 100 and the body are connected by an aluminum sleeve 300 to tighten them.

[0038] Reference Figure 1 and Figure 5 As shown, the tensioning fixture includes a first sleeve 1, a second sleeve 2 and a tensioning assembly 3, wherein the first sleeve 1 is sleeved on the aluminum sleeve 300, the second sleeve 2 is sleeved on the steel cable 100, and the second sleeve 2 abuts against the first sleeve 1. One end of the tensioning assembly 3 is connected to the second sleeve 2, and the other end is connected to the anchor point 4.

[0039] In the process of connecting the cable head 200 and the anchor point 4, the cable head 200 is connected to the anchor point 4 after the cable head 200 is in place by the tensioning assembly 3. During the tensioning process, the tensioning force of the tensioning assembly 3 acts on the second sleeve 2. Since the second sleeve 2 and the first sleeve 1 are against each other, the tensioning force is transferred to the first sleeve 1. Since the first sleeve 1 is sleeved on the aluminum sleeve 300, the tensioning force is transferred to the aluminum sleeve 300, which can avoid the tensioning assembly 3 and the PE layer from interacting and causing damage to the PE layer. The first sleeve 1 is sleeved on the aluminum sleeve 300 to limit the shape of the aluminum sleeve 300, thereby preventing the aluminum sleeve 300 from being deformed due to uneven force.

[0040] Specifically, referring to Figure 2 As shown, the first sleeve 1 includes a cylinder 11 and a first end plate 12. A cavity 13 for surrounding the aluminum sleeve 300 is formed in the cylinder 11. The first end plate 12 is located at the end surface of the cylinder 11 and is integrally formed with the cylinder 11. A through hole 14 is provided on the first end plate 12, and the through hole 14 is used to accommodate the steel cable 100 passing through. And the diameter of the through hole 14 is smaller than the outer diameter of the aluminum sleeve 300, so that the first end plate 12 and the end surface of the aluminum sleeve 300 are abutted. Since the first end plate 12 and the aluminum sleeve 300 are abutted, the tension force acting on the first sleeve 1 is transmitted to the aluminum sleeve 300.

[0041] It should be noted that, in other embodiments, the first sleeve 1 may also only include the cylinder 11, and the cylinder 11 clamps the aluminum sleeve 300 to increase the friction between the cylinder 11 and the aluminum sleeve 300, so that the tension force acting on the first sleeve 1 is transmitted to the aluminum sleeve 300.

[0042] Specifically, refer to Figure 3 As shown, the first sleeve 1 includes a first sleeve body 15 and a second sleeve body 16 symmetrically arranged along its axial direction, and the first sleeve body 15 and the second sleeve body 16 are detachably connected. Specifically, one side of the first sleeve body 15 is connected to the second sleeve body 16 through a first hinge, so that the first sleeve body 15 and the second sleeve body 16 can rotate relative to each other. Although not shown in the figure, a first connecting ear can be provided on the side of the first sleeve body 15 and the second sleeve body 16, and the two first connecting ears can be connected by bolts to achieve a detachable connection. It is also possible to respectively provide first connecting ears on both sides of the first sleeve body 15 and the second sleeve body 16, and connect the corresponding first connecting ears by bolts. It should be noted that in other embodiments, structures such as buckles and hoop can also be used to achieve a detachable connection between the first body 15 and the second body 16. It should be noted that in other embodiments, the first sleeve 1 can also be an integral sleeve directly sleeved on the aluminum sleeve 300.

[0043] Specifically, in order to protect the PE layer at the cable head 200 and avoid the PE layer being damaged due to the interaction between the first sleeve 1 and the cable head 200 during the tensioning process, the end surface of the first sleeve 1 is prevented from contacting the cable head 200 on the steel cable 100. Specifically, the length of the first sleeve 1 can be made shorter than the length of the aluminum sleeve 300, so that the first sleeve 1 does not contact the cable head 200.

[0044] Specifically, refer to Figure 1 and Figure 4 As shown, a stopper 21 is provided on the surface of the second sleeve 2. The tensioning rope at one end of the tensioning assembly 3 is sleeved on the surface of the second sleeve 2 and abuts against the stopper 21, and the stopper 21 serves as a force point between the second sleeve 2 and the tensioning assembly 3. This facilitates the tensioning assembly 3 to apply tensioning force to the second sleeve 2. The second sleeve 2 can be provided with a plurality of stopper blocks 21 along its axial direction, and the tensioning rope can be sleeved at different positions as needed during the actual construction process on site, so that the corresponding stopper blocks 21 serve as force points.

[0045] Specifically, continue to refer to Figure 4 As shown, the second sleeve 2 includes a segment A 22 and a segment B 23 symmetrically arranged along its axial direction, and the segment A 22 and the segment B 23 are detachably connected. Specifically, one side of the segment A 22 is connected to the segment B 23 by a second hinge, so that the segment A 22 and the segment B 23 can rotate relative to each other. Although not shown in the figure, a second connecting ear 25 can be respectively provided on the side of the segment A 22 and the segment B 23, and the two second connecting ears 25 are connected by bolts, so as to realize the detachable connection between the segment A 22 and the segment B 23. The second connecting ears 25 can also be respectively provided on both sides of the segment A 22 and the segment B 23, and the corresponding second connecting ears 25 are connected by bolts. It should be noted that in other embodiments, structures such as buckles and hoop can also be used to realize the detachable connection between the segment A 22 and the segment B 23.

[0046] Specifically, in this embodiment, the tensioning assembly 3 may be an electric hoist, and in other embodiments, other tensioning structures such as pulleys and oil cylinders may also be selected.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
