Description

Technical Field

[0001] The utility model relates to the technical field of cable clamps, in particular to a straight-line 110kv cable clamp. Background Art

[0002] A clamp is a component that uses one material to hold or clamp another material. It is a fastener. The clamp device is composed of a hoop plate, a wing plate, a tie plate, a bolt and an inner liner. There are many kinds of clamps, cable clamps, pole clamps, wire clamps, suspension wire clamps, and stainless steel clamps are all commonly used.

[0003] At present, after the cable is laid, a cable clamp is needed to fix the cable on the bracket. Traditional cable clamps are mostly single separated structures, that is, two semi-annular clamps are used to fix the cable. Due to the small contact area between the cable and the existing clamp, under the action of mechanical vibration, the mechanical stress on the cable structure layer in contact with the clamp is too concentrated, causing the cable structure to deform and even cause cable line failure, especially the position where the outer surface of the cable contacts the inner wall at both ends of the clamp. When subjected to external force for a long time, it is easy to cause stress concentration at the position where the outer surface of the cable contacts the inner wall at both ends of the clamp, which in turn causes damage to the cable and affects the normal use of the cable. In view of this, we propose a one-shaped 110kv cable clamp. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a straight-line 110kv cable clamp to solve the technical problem that after the current cable clamp is fixed on the cable, it is easy to cause stress concentration at the position where the outer surface of the cable contacts the inner walls of the two ends of the clamp under the action of external force for a long time, causing damage to the cable.

[0011] Preferably, the flexible strip 1 and the flexible strip 2 are both arc-shaped strip structures respectively fitted to the inner edge surfaces of the semi-annular main hoop and the semi-annular secondary hoop.

[0012] Preferably, the facing ends of two adjacent semi-annular main hoops are each provided with a connecting plate 1, one side of the connecting plate 1 is connected to the semi-annular main hoop structure, and the end structures of the semi-annular main hoops at both ends are connected to a fixing plate 1.

[0027] See also Figure 2-Figure 4 The flexible strip one symmetrically crosses to form an X-shaped structure, with the intersection point as the dividing line, to form a short head end one 301 and a long head end one 302 arranged toward both ends; the flexible strip two symmetrically crosses to form an X-shaped structure, with the intersection point as the dividing line, to form a short head end two 401 and a long head end two 402 arranged toward both ends; the short head end one 301 and the long head end two 402 are arranged toward the same end and form a clamping structure; the short head end two 401 and the long head end one 302 are arranged toward the same end and form a clamping structure; the flexible strip one and the flexible strip two are both arc-shaped strip structures respectively fitted to the inner edge surfaces of the semi-annular main hoop 102 and the semi-annular secondary hoop 201.

[0028] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 , the facing ends of two adjacent semi-annular main hoops 102 are each provided with a connecting plate 103, one side of the connecting plate 103 is structurally connected to the semi-annular main hoops 102, and the end structures of the semi-annular main hoops 102 at both ends are structurally connected to a fixing plate 105, the outer edge surfaces of two adjacent semi-annular secondary hoops 201 are commonly structurally connected to a straight plate 202, and the facing ends of two adjacent semi-annular secondary hoops 201 are each provided with a connecting plate 204, one side of the connecting plate 204 is structurally connected to the semi-annular secondary hoops 201, and the end structures of the semi-annular secondary hoops 201 at both ends are structurally connected to a fixing plate 203 corresponding to the position of the fixing plate 105, the inner edge surfaces at both ends of the semi-annular main hoops 102 are each formed with a limiting protrusion 104 for positioning the cable, and the inner edge surfaces at both ends of the semi-annular secondary hoops 201 are each formed with a limiting protrusion 205 for positioning the cable.

[0029] Working principle: when in use, the cable can be placed in the semi-annular main hoop 102 so that the flexible strip 1 fits the surface of the cable, and then the semi-annular secondary hoop 201 is covered on the outside of the cable corresponding to the mounting seat 101 so that the flexible strip 2 fits the surface of the cable, and then the prepared bolts are screwed between the fixing plate 105 and the fixing plate 203 to complete the fixation of the cable.

When subjected to external force, the stress at the position where the outer surface of the cable contacts the ends of the semi-annular main hoop 102 and the semi-annular auxiliary hoop 201 is too concentrated. When the cable is fixed by the semi-annular main hoop 102 and the semi-annular auxiliary hoop 201, the flexible strips 1 and 2 can play a buffering and anti-slip effect, especially when external force acts on the cable, it can prevent the cable from being damaged by hard contact with the semi-annular main hoop 102 and the semi-annular auxiliary hoop 201, and the flexible strips 1 and 2 are designed to be X-shaped, and the short head end 1 301 and the long head end 2 402, as well as the short head end 2 401 and the long head end 1 302 are respectively formed toward one end to form a clamping structure in which the long head end and the small head end cooperate with each other, which is beneficial to the clamping effect on the cable.
