Description
Technical Field
[0001] This application relates to the field of electrical hardware, and particularly to an anti-slip suspension clamp. Background Art
[0002] The suspension clamp of a transmission line is one of the main components for fixing and supporting an overhead conductor, and is an important part of an overhead power line. Its function is to suspend the conductor on a straight-line tower, directly connect to the cross arm of the tower through a suspension insulator, or hang the lightning protection wire on the straight-line tower to support the transposed conductor. The suspension clamp should have sufficient holding strength for the conductor under normal operation or in case of wire breakage of the line, so as to avoid insufficient safety distance from the crossing structure due to the conductor falling off the clamp after a wire break in an adjacent span.
[0003] However, under the action of the environment (wind force, ice coating, rainfall, temperature change, etc.), the natural frequency vibration of the tower, and the vibration of the conductor, there is a permanent relative movement between the clamp and the conductor. Over time, wear will occur between the conductor and the clamp, as well as between the clamp components, resulting in consumption and failure of both. After the conductor is installed on the suspension clamp, the conductor is prone to relative slip with the suspension clamp under the action of external forces such as wind force, and relative sliding occurs between the two, leading to wear between the suspension clamp and the conductor.
[0004] Therefore, it is necessary to design an anti-slip suspension clamp with a stable structure that can firmly fix the cable. Summary of the Invention

Detailed implementation manners
[0029] In order to more clearly illustrate the overall concept of the present invention, the following will be further described in detail by way of examples in combination with the accompanying drawings of the specification.
[0030] It should be noted that many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
[0031] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. However, indicating a direct connection means that there is no connection relationship constructed through an excessive structure between the two connected main bodies, and they are only connected through the connection structure to form an integral body. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0032] As Figures 1 to 5 shown, the present application provides an anti-slip suspension clamp for clamping a wire to prevent the wire from sliding and causing wear to the equipment, resulting in premature detachment, and provides a device that is more stable and reduces wire sliding.
[0033] In an embodiment of the present application
[0034] As Figures 1 - 2 shown: an anti-slip suspension clamp includes a clamp bracket 1 and a clamping mechanism 2 for clamping a wire 3 within the clamp bracket 1.
[0035] The clamp bracket 1 includes a U-shaped bottom plate 11 and support plates 12 provided on both sides of the U-shaped bottom plate 11. Connection columns 13 are provided on each of the support plates 12, connection plates 14 are provided on the connection columns 13, and connection holes 10 are provided on the connection plates 14; the connection plates 14 and the connection holes 10 are used to connect an insulator to suspend the entire clamp device.
[0036] The U-shaped bottom plate 11 and the support plates 12 of the entire clamp are integrally cast, and a receiving space is formed between the two support plates 12.
[0037] In traditional devices, the wire is directly placed on the U-shaped bottom plate 11. However, in this way, the wire is not firmly fixed. The strong winds, ice rain, and temperature changes during day and night alternation in the natural environment will all affect the connection tightness between the wire and the clamp, resulting in moving friction between the wire and the clamp. After long-term use, wear will occur.
[0038] Therefore, a clamping mechanism 2 for clamping the wire 3 is provided between the two support plates 12. The clamping mechanism 2 includes a wire clamping seat 21, a left stop block 22, and a right stop block 23. A wire passing hole 210 is provided inside the wire clamping seat 21, and the wire passing hole 210 is used to fix the wire; the left stop block 22 and the right stop block 23 are respectively arranged on the two support plates 12, and the left stop block 22 and the right stop block 23 surround to form an upper-open receiving space 100, and the wire clamping seat 21 is clamped in the receiving space 100.
[0039] As Figure 5 shown, the wire passes through the wire passing hole 210 on the wire clamping seat 21, and a number of anti-slip strips 213 arranged in sequence are provided in the wire passing hole 210.
[0040] It is fixed in the wire passing hole 210, and then the wire clamping seat 21 is fixed and restricted by the left stop block 22 and the right stop block 23.
[0041] As Figures 3 - 4 shown, in the present utility model, the left stop block 22 and the right stop block 23 are symmetrically arranged, and the left stop block 22 and the right stop block 23 are respectively fixed on the corresponding support plate 12.
[0042] A left limiting groove 220 is provided on the left stop block 22, a right limiting groove 230 is provided on the right stop block 23, and the wire clamping seat 21 is provided with limiting protrusions 211 corresponding to the shapes of the left limiting groove 220 and the right limiting groove 230.
[0043] The left stop block 22 is symmetrically connected by two symmetrically arranged right-angled triangular plates 221. The tops of the right-angled plate edges of the two right-angled triangular plates 221 are connected together, and the hypotenuses of the two right-angled triangular plates 221 surround to form the left limiting groove 220. Similarly, the right limiting groove 230 is also symmetrically arranged on the other support plate (12).
[0044] All the right-angled triangular plates 221 and the entire wire clip bracket 1 are integrally cast, which can ensure the strength of the whole.
[0045] The limiting protrusions 211 on both sides of the wire clamping seat 21 respectively abut against the left limiting groove 220 or the right limiting groove 230, and the shapes of the limiting protrusions 211 conform to the shapes of the left limiting groove 220 or the right limiting groove 230. By connecting the tops of the right-angled plate edges of the two right-angled triangular plates 221 together, a wedge-shaped left limiting groove 220 is formed. At the same time, the shapes of the limiting protrusions 211 on both sides conform to the wedge-shaped left limiting groove 220 and the right limiting groove 230. During installation, it only needs to be inserted from above to firmly fix the entire wire clamping seat 21.
[0046] In order to more conveniently place the wire 3 into the wire passing hole 210, a tightening and loosening groove 212 is opened on the wire clamping seat 21. The lower end of the tightening and loosening groove 212 communicates with the wire passing hole 210, so that the tightening and loosening groove 212 can be adjusted during installation, thereby more conveniently loosening and clamping.
[0047] In order to adjust the loosening and clamping of the tightening and loosening groove 212, so as to adjust the clamping degree of the wire 3, a pair of fixed buckles 4 are further provided on the wire clamping seat 21. The fixed buckle 4 includes an intermediate plate 41 and two buckle plates 42 arranged at both ends of the intermediate plate 41. Each buckle plate 42 abuts against the side wall of the wire clamping seat 21.
[0048] A screw component 5 is further provided on the fixed buckle 4, and the screw component 5 sequentially penetrates through the fixed buckle 4 and the wire clamping seat 21. By setting the cooperation of the fixed buckle 4 and the screw component 5, the wire passing hole 210 and the wire can be in interference fit to prevent the sliding of the wire. A pair of inverted U-shaped fixed buckles 6 are further provided on the wire clamp bracket 1. A fixed buckle connection seat 111 is provided on the U-shaped bottom plate 11, and a fixed buckle limiting groove 121 is provided on the support plate 12.
[0049] In this application, a left stop block and a right stop block are arranged inside the wire clamp bracket, and the wire is fixed in a wire clamping seat. The wire clamping seat can prevent the left and right movement of the wire clamping seat and the sliding of the wire by being clamped and fixed with the left stop block and the right stop block, reducing the wear of the wire and the whole device, and improving the service life and safety of the whole suspension clamp; through the detachable clamping method, the wire clamping seat and the wire can be quickly replaced, reducing the maintenance difficulty; by arranging anti-slip strips in the wire passing hole, the wire is further fixed, and the tightening groove is used to adjust the tightness between the wire passing hole and the wire. Moreover, by setting the cooperation of the fixed buckle and the screw component, the wire passing hole and the wire can be in interference fit to prevent the sliding of the wire.
[0050] The technical features of the above embodiments can be combined arbitrarily, and there is no limitation on the execution order of the method steps. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0051] The above embodiments only represent several implementation manners of this application, and the description is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of this application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of this application should be subject to the appended claims.
