Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of support clamps for safety backup clamp. BACKGROUND

[0002] The power industry uses safety backup clamp for high-voltage line generally. Safety backup clamp provides additional mechanical support, effectively preventing the loosening or breakage of the conductor or optical cable caused by external environmental factors (such as wind vibration, temperature change, etc.). After the installation of safety backup clamp in the field, due to wind, vibration and other factors, it will constantly rub with strain clamp. The external material of compression strain clamp is aluminum, which is relatively soft and easy to wear. Therefore, measures need to be taken to prevent the contact between safety backup clamp and strain clamp.

[0003] In the prior art, when installing safety backup clamp, a high-picking hardware is provided to increase the distance between safety backup clamp and strain clamp at the connection end, which can prevent the main support cable and the standby support cable from contacting near the connection end. SUMMARY

[0004] The inventor found that for simple lines, high-picking hardware can solve the above problems. However, in high-voltage lines with multiple lines intersecting, such as eight-bundle conductors, the installation space between the conductors near the connection end is limited. The installation of high-picking hardware will increase the installation space of safety backup clamp and strain clamp at the connection end, resulting in insufficient installation space for some safety backup clamps and inability to install.

[0005] The utility model aims to provide a kind of support clamps for safety backup clamp with novel and unique structure, convenient to use, and can reduce the installation space of safety backup clamp and strain clamp at the connection end;Specific technical solutions are as follows:

[0006] A kind of support clamps for safety backup clamp, including support clamp body, the both ends of the body are respectively provided with locking ring for locking support cable;The locking ring is composed of locking slot and lock catch at the end of the body;One end of the lock catch is hinged to the body, and the other end is fixedly connected to the body.

[0007] Further, the locking slot is a semicircular cylindrical groove;The lock catch is provided with a semicircular ring-shaped part adapted to the locking slot.

[0008] Further, the end fixedly connected to the body is connected by bolt.

[0009] Further, the end of the bolt away from the nut is provided with a pin hole.

[0010] Further, the center distance of the two locking rings is between 50 to 500 millimeters.

[0011] Further, the inner wall of the locking ring is provided with a protective rubber pad.

[0017] The utility model can be embodied in various different forms, and should not be understood as being limited to the exemplary embodiments described herein.

[0018] For easy description, spatial relative terms such as "upper", "lower", "left", "right" and the like can be used herein for describing the relationship of one element or feature to another element or feature shown in the drawings. It should be understood that, in addition to the orientation shown in the drawings, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the drawings is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "below" can include both upward and downward orientations. The device can be positioned in other ways (rotated 90 degrees or positioned in other orientations), and the spatial relative description used herein can be interpreted accordingly. EMBODIMENT 1

[0019] As Figure 1As shown, the safety backup cable clamp in this embodiment includes a support cable clamp body 1. The upper end of the body 1 is provided with an upper locking ring for locking the spare support cable; the lower end is provided with a lower locking ring for locking the main support cable. Of course, the positions of the main support cable and the spare cable can be interchanged. Both the upper and lower locking rings consist of a locking groove and a latch at the end of the body. One end of the latch is hinged to the body, and the other end is fixedly connected to the body.

[0020] The locking groove should match the cross-section of the main support cable or the spare support cable being locked; it is generally a semi-cylindrical groove; correspondingly, the latch is provided with a semi-circular annular part that matches the locking groove.

[0021] The end of the latch that connects to the body can be glued, welded, or riveted; however, bolts are the best option for easy replacement.

[0022] To prevent the nut from loosening, bolt 5 has a pin hole at the end furthest from the nut. In use, an R-type pin, B-type pin, or other pin can be inserted into the pin hole to prevent the bolt from falling off. Alternatively, one end of the hinge shaft can be designed as a large cap shape, with a pin hole at the other end; this pin can then be used to prevent the hinge shaft from falling off.

[0023] The center distance between the two locking rings should be between 100 and 200 mm; this can effectively isolate the main support cable and the backup support cable from contact, ensure a small installation space, and facilitate the installation of safety backup clamps in complex circuits.

[0024] If the connection between the two locking rings is long, a weight-reducing groove 4 can be opened in the connection to help reduce the weight of the support clamp.

[0025] To reduce wear on the spare support cable, a protective rubber pad 2 can be installed on the inner wall of the locking ring. The protective rubber pad 2 can also balance the locking force of the support clamp, the spare cable, and the main cable, reducing local deformation. Example 2

[0026] like Figure 2 As shown, the support clamp in this embodiment is basically the same as that in embodiment 1; the difference is that the unthreaded countersunk nut holes in the locking bolt holes for installing the locking bolt 5 are all located on the top; the threaded holes are all located on the bottom; specifically, the upper edge of the first locking buckle is provided with a countersunk nut hole; it cooperates with the threaded hole at the upper end of the body 1; it is used to lock the upper locking buckle 3 with the locking bolt 5; similarly, the countersunk nut hole of the locking bolt for locking the lower locking buckle 6 is located at the lower end of the body 1; it cooperates with the threaded hole provided on the lower locking buckle 6.

[0027] Although the support wire clamp in embodiment 2 is asymmetric at both ends, and the direction needs to be distinguished when used, but in high-altitude operation, it is difficult to stand steadily, the nut counterbore is arranged at the upper side, after the bolt is put in, even if the bolt is not tightened in time, the bolt is not easy to be unscrewed; it is beneficial to reduce the tension degree of the operator, and is also beneficial to improve the success rate of the lock buckle locking.

[0028] When used, the support wire clamp is installed at the support position; the upper lock buckle 3 is buckled; the bolt is inserted into the nut counterbore and screwed into the threaded hole of the body 1; it is not tightened first, and then the position of the wire clamp is adjusted and then tightened; the lower lock buckle 6 is buckled, the bolt is inserted into the nut counterbore and screwed into the threaded hole of the body 1 or the lower lock buckle 6; the bolt is tightened; the flower basket is rotated, the standby support cable is tensioned, the standby support cable is substantially parallel to the main cable, and then the bolt for locking the upper lock 3 is tightened; the pin is inserted; the installation is completed.

[0029] As shown in Figure 3 The safety backup wire clamp in the embodiment uses the support wire clamp to fix the standby support cable connected with the safety backup wire clamp and the main support cable connected with the strain clamp respectively through the support position installed at about 20 cm away from the initial position of the cable stranding section of the safety backup wire clamp; the cable from the support position to the connection position is tensioned by the flower basket respectively; the connection position is close to parallel; neither friction occurs, nor the connection space occupied by the connection end is reduced; it is suitable for the installation of the safety backup wire clamp of complex line.

[0030] The above examples are only used to illustrate the utility model, in addition to this, there are many different embodiments, and these embodiments are all the embodiments that the person skilled in the art can think of after understanding the utility model idea, therefore, here is not enumerated one by one.
