Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to a suspension wire clamp. Background Art

[0002] Suspension clamps are a special type of electrical hardware, mainly used for the suspension and fixing of cables and lightning conductors in power lines. The design of this type of clamp allows for easy movement or adjustment when necessary, thus meeting the different needs of power line installation, maintenance and adjustment.

[0003] When the tower is tilted and deformed due to uneven surface settlement, an unbalanced tension difference will be generated in the cables on both sides of the tower. The use of traditional suspension clamps cannot allow the cables to move inside the suspension clamps, and cannot eliminate the tension difference generated by the cables on both sides of the tower. As a result, the tower is subjected to excessive unbalanced tension, resulting in bending and deformation of the tower rods and tower collapse accidents. Utility Model Content

[0004] The utility model provides a suspension wire clamp, which solves the technical problem that when cables on both sides of an iron tower generate too large an unbalanced tension difference, the excessive unbalanced tension cannot be eliminated in time, resulting in bending and deformation of iron tower rods and collapse of the tower.

[0005] To solve the above technical problems, the technical solution of this novel invention is as follows:

[0006] A suspension wire clamp, comprising:

[0007] A wire clamp body with a grooved structure;

[0008] A fixing frame hinged to the wire clamp body;

[0009] A cable sleeve penetrating the wire clamp body and fixedly connected to the inner surface of the wire clamp body, wherein a cable is sleeved inside the cable sleeve;

[0010] A plurality of fastening grooves are symmetrically arranged on the outer surface of the wire clamp body, and the plurality of fastening grooves are connected by U-shaped bolts;

[0011] When the tension difference between the wire clamp bodies on both sides of the tower is greater than a preset threshold, the U-bolt is deformed, causing the cable to move inside the cable sleeve.

[0012] Optionally, the inner diameter of the cable sleeve is larger than the outer diameter of the cable.

[0013] Optionally, two ends of the U-shaped bolt pass through the outer surface of the bottom of the wire clamp body and are fixedly connected to the fastening grooves symmetrically arranged on the first end and the second end of the wire clamp body.

[0014] Optionally, the fastening groove and the wire clamp body are integrally formed.

[0015] Optionally, a first through hole is formed at the top of the first end and the second end of the wire clamp body;

[0016] The first through holes at the first end and the second end of the wire clamp body are connected by a connecting rod.

[0017] Optionally, the fixing frame includes a side panel;

[0018] The first end of the side plate is fixedly connected to the connecting rod.

[0019] Optionally, a second through hole is formed at the second end of the side plate, and a rotating shaft is disposed in the second through hole;

[0020] The fixing frame is connected to the iron tower via the rotating shaft.

[0021] Optionally, the cable sheath is made of insulating and heat-insulating material.

[0022] The above solution of the utility model includes at least the following beneficial effects:

[0023] The above scheme of the utility model includes: a wire clamp body with a groove structure; a fixing frame hinged to the wire clamp body; a cable sleeve penetrating the wire clamp body and fixedly connected to the inner surface of the wire clamp body, wherein a cable is sleeved inside the cable sleeve; a plurality of fastening grooves are symmetrically arranged on the outer surface of the wire clamp body, and the plurality of fastening grooves are connected by U-shaped bolts; when the tension difference between the wire clamp bodies on both sides of the iron tower is greater than 20%, the U-shaped bolts are deformed, so that the cable moves inside the cable sleeve. The utility model sets a cable sleeve and fixes the cable sleeve to the bottom surface inside the wire clamp body. When the unbalanced tension difference on both sides of the iron tower is too large, the cable moves inside the cable sleeve, thereby eliminating the unbalanced tension difference on both sides of the iron tower.

Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a suspension wire clamp, comprising:

[0030] A wire clamp body 1 with a grooved structure;

[0031] A fixing frame 2 hinged to the wire clamp body 1;

[0033] A plurality of fastening grooves 4 are symmetrically arranged on the outer surface of the wire clamp body 1, and the plurality of fastening grooves 4 are connected by U-shaped bolts 5;

[0034] When the tension difference between the clamp bodies 1 on both sides of the tower is greater than a preset threshold, the U-bolt 5 is deformed, causing the cable 6 to move inside the cable sleeve 3. Preferably, the preset threshold is 20%, which is adjusted according to different usage environments.

[0035] In the above embodiment, the utility model provides a fastening groove 4 on the outer surface of the wire clamp body 1, and provides a U-shaped bolt 5 between the fastening grooves 4, so as to fix the cable 6 passing through the inside of the wire clamp body 1. By hingedly connecting the fixing frame 2 on the top of the wire clamp body 1, the wire clamp body 1 can be connected to the iron tower to fix the cable 6. By providing a cable sleeve 3 and fixing the cable sleeve 3 to the bottom surface inside the wire clamp body 1, when the unbalanced tension difference on both sides of the iron tower is too large, the cable 6 can be moved inside the cable sleeve 3, so as to eliminate the unbalanced tension difference on both sides of the iron tower. This avoids the occurrence of bending and deformation of the iron tower rods and tower collapse accidents due to excessive unbalanced tension on the iron tower.

[0036] In an optional embodiment of the present invention,

[0037] The inner diameter of the cable sleeve 3 is larger than the outer diameter of the cable 6 .

[0038] In the above embodiment, the cable sheath 3 is a tubular structure, the cross-sectional shape of the cable sheath 3 is the same as the cross-sectional shape of the cable 6, the outer diameter of the cable sheath 3 is smaller than the width of the wire clamp body 1 and the inner diameter of the cable sheath 3 is larger than the outer diameter of the cable 6, so that the cable 6 can be easily moved in the cable sheath 3.

[0039] In an optional embodiment of the present invention,

[0040] Both ends of the U-shaped bolt 5 pass through the outer surface of the bottom of the wire clamp body 1 and are fixedly connected to the fastening grooves 4 symmetrically arranged on the first end and the second end of the wire clamp body 1 .

[0041] In the above embodiment, both ends of the U-shaped bolt 5 pass through the fastening grooves 4 symmetrically arranged on the first end and the second end of the wire clamp body 1, and the U-shaped bolt 5 is fixedly connected to the inner surface of the fastening groove 4 by a nut.

[0042] When in use, by adjusting the fixing positions of the nut and the U-bolt 5 , cables 6 with different diameters can be fixed to the wire clamp body 1 .

[0043] In an optional embodiment of the present invention,

[0044] The fastening groove 4 is integrally formed with the wire clamp body 1 .

[0045] In the above embodiment, the fastening groove 4 is located outside the first end and the second end of the wire clamp body 1, which serves to facilitate the insertion of the U-shaped bolt 5. The side of the fastening groove 4 is connected to the inner surface of the wire clamp body 1, which facilitates the use of a nut to fix the U-shaped bolt 5. The fastening groove 4 is integrally formed with the wire clamp body 1, which serves to improve the structural strength of the wire clamp body 1.

[0046] In an optional embodiment of the present invention,

[0047] The first end and the top of the second end of the wire clamp body 1 are both provided with a first through hole;

[0048] The first through holes at the first end and the second end of the wire clamp body 1 are connected by a connecting rod 22 .

[0049] like Figure 2 As shown, in the above embodiment, the length of the connecting rod 22 is greater than the distance between the first end and the second end of the wire clamp body 1, so as to prevent the cable 6 from deforming the wire clamp body 1 under the action of lateral unbalanced tension, causing the connecting rod 22 to fall off from the first through hole.

[0050] In an optional embodiment of the present invention,

[0051] The fixing frame 2 includes a side plate 21;

[0052] The first end of the side plate 21 is fixedly connected to the connecting rod 22 .

[0053] In an optional embodiment of the present invention,

[0054] A second through hole is formed at the second end of the side plate 21, and a rotating shaft 23 is disposed in the second through hole;

[0055] The fixing frame 2 is connected to the iron tower via the rotating shaft 23 .

[0056] like Figure 2 As shown, in the above two embodiments, the fixing frame 2 includes two side plates 21, and the first ends of the two side plates 21 are fixedly connected to the outer surface of the connecting rod 22, so as to fix the fixing frame 2 to the wire clamp body 1.

[0057] The rotating shaft 23 passes through the second through hole and is rotatably connected to the side plate 21 , and one end of the rotating shaft 23 is fixedly connected to the iron tower, so as to realize the rotatable connection between the wire clamp body 1 and the iron tower.

[0058] In an optional embodiment of the present invention,

[0059] The cable bushing 3 is made of insulating and heat-insulating material.

[0060] In the above embodiment, the cable sleeve 3 is made of insulating and heat-insulating material to avoid fire caused by the cable 6 moving in the cable sleeve 3. Furthermore, the cable sleeve 3 is made of elastic material to facilitate the clamp body 1 to fix the cable 6.

[0061] The method of using the suspension clamp described in this application is as follows:

[0062] When the iron tower is tilted and deformed due to uneven settlement of the ground, the cables on both sides of the iron tower will produce a large tension difference on the iron tower, causing the iron tower to bear unbalanced tension and torque. And the unbalanced tension and torque borne by the iron tower increase with the increase of the degree of tilt deformation of the iron tower. Therefore, before mining the mineral deposits located at the bottom of the iron tower, it is necessary to notify the line operation and maintenance unit in advance to monitor the deformation and settlement of the iron tower in real time. When the unbalanced tension difference from the cables 6 on both sides of the iron tower reaches ±20%, that is, when the unbalanced tension difference generated by the cables 6 on both sides of the iron tower exceeds the bearing capacity of the U-bolt 5, the wire clamp body 1 connected to the iron tower and the U-bolt 5 fixed to the fastening groove 4 are deformed under the action of the lateral tension of the cable 6. Under extreme conditions, the U-bolt 5 will break. At this time, the U-bolt 5 and the wire clamp body 1 cannot fix the cable 6, and the cable 6 moves in the cable sleeve 3 to the side with greater tension under the action of the longitudinal unbalanced tension, thereby eliminating the tension difference of the cables 6 on both sides of the iron tower caused by the tilt deformation of the iron tower. Finally, after the tower settlement is basically completed, the workers will reset the U-bolts 5 or replace them with new U-bolts 5.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
