The clamping block 123 is used for extending into the groove of the tension-resistant drainage yoke plate 200, and the adjusting rod 122 is used for driving the clamping block 123 to deform so as to enable the tension-resistant drainage yoke plate 200 to be unfolded.
In the use process of the tension-resistant drainage yoke plate installation device 100, first, the first fixing piece 111 on the lifting mechanism 110 is connected with the tension-resistant drainage yoke plate 200, the second fixing piece 112 is connected with the drainage wire 300, and then, the lifting assembly 113 is adjusted so that the second fixing piece 112 moves close to the first fixing piece 111, so that the bolt at the connecting part of the tension-resistant drainage yoke plate 200 is not stressed; then, stretch into the gap of strain insulator drainage yoke plate 200 with the fixture block 123 of expansion mechanism 120, operate adjusting lever 122, make adjusting lever 122 be close to fixture block 123 motion in expansion body 121 and order about fixture block 123 and take place deformation expansion, thereby prop up strain insulator drainage yoke plate 200, at this moment, because drainage wire 300 is lifted, do not have the effect of pulling the junction, the staff can easily dismantle the bolt, and, because fixture block 123 prop up strain insulator drainage yoke plate 200, not hard up between drainage pressure plate and the strain insulator drainage plate, can freely pull out and resume drainage wire 300 crimping plate, and then be favorable to improving the installation and the dismantlement efficiency of drainage wire 300 pressure plate, need not to beat drainage wire 300 pressure plate and strain insulator drainage yoke plate 200, avoid drainage wire 300 pressure plate and strain insulator drainage yoke plate 200 to be beaten and warp, be favorable to improving drainage wire 300 pressure plate and drainage yoke plate's life.
For further understanding and description of the height direction of the expansion body 121, taking fig. 3 as an example, the height direction of the expansion body 121 is the direction indicated by any arrow on the straight line S 1 in fig. 3.
It should be noted that, the adjusting rod 122 is used for driving the fixture block 123 to deform, so that the tension-resistant drainage yoke plate 200 is expanded, and it should be understood that the tension-resistant drainage yoke plate 200 is U-shaped, the adjusting rod 122 drives the fixture block 123 to deform, and makes the tension-resistant drainage yoke plate 200 expand, the gap of the U-shaped groove is increased, and the expansion mode is in the range that the tension-resistant drainage yoke plate 200 can bear deformation, and the non-recoverable permanent deformation and cracking of the tension-resistant drainage yoke plate 200 cannot be caused.
In one embodiment, referring to fig. 3 and fig. 4, the adjustment hole 124 includes a first hole section 1241 and a second hole section 1242. The first hole section 1241 is disposed in the expansion body 121, the second hole is disposed in the clamping block 123, and the inner diameter of at least one section of the second hole section 1242 gradually decreases from the connection point to the bottom end of the clamping block 123 along the height direction of the expansion body 121. In this way, in the process of moving in the adjusting hole 124, as the inner diameter of the second hole section 1242 is gradually reduced, the adjusting rod 122 continues to move downwards, and the inner wall of the second hole section 1242 is pressed against, so that the adjusting rod 122 expands the clamping block 123 to deform and expands the U-shaped groove of the U-shaped tension-resistant drainage yoke plate 200. When the adjusting rod 122 moves upwards, the second hole section 1242 is released from the pressing action by the adjusting rod 122, so that the clamping block 123 can recover the original shape under the pressure action of the tension-resisting drainage yoke plate 200 or under the self-elastic action, and can be taken out from the U-shaped groove.
Optionally, the deformation of the clamping block 123 may be that the clamping block 123 is connected with the expansion body 121, the adjusting rod 122 drives the clamping block 123 to elastically deform, or that the clamping block 123 is movably connected with the expansion body 121, and the adjusting rod 122 drives the clamping block 123 to move, so as to generate deformation.
In one embodiment, referring to fig. 3 and 4, the clamping block 123 is rotatably connected to an end of the expansion body 121 extending away from the adjusting rod 122, and when the adjusting rod 122 is in abutting engagement with the inner wall of the second hole section 1242, the clamping block 123 rotates outwards along the circumferential direction. Thus, when the adjusting rod 122 extends downwards, the clamping block 123 is driven to rotate outwards, so that the U-shaped groove of the tension-resistant drainage yoke plate 200 is opened. When the adjusting rod 122 moves upwards, the U-shaped groove restores the shape, so that the clamping blocks 123 move close to each other, and the original shape is restored. The clamping block 123 is connected with the expansion body 121 in a rotating mode, so that the expansion mechanism 120 can be reused, and the service life of the expansion mechanism 120 is prolonged.
In one embodiment, referring to fig. 3 and 4, the clamping block 123 includes a first expansion portion 1231 and a second expansion portion 1232, and the first expansion portion 1231 and the second expansion portion 1232 are disposed at opposite ends of a central axis of the second hole section 1242. The first expansion part 1231 and the second expansion part 1232 enclose a second hole section 1242 when being closed, and the first expansion part 1231 and the second expansion part 1232 are both rotationally connected with the expansion body 121. In this way, when the adjusting rod 122 extends downward into the second hole section 1242, the inner diameter of the second hole section 1242 is continuously reduced, so that the adjusting rod 122 struts the first expansion part 1231 and the second expansion part 1232, thereby expanding the U-shaped groove of the strain drainage yoke plate 200. When the adjusting rod 122 moves upwards away from the second hole section 1242, the U-shaped groove restores the shape, so that the first expansion part 1231 and the second expansion part 1232 are close to each other, and the original shape of the clamping block 123 is restored. The split first expansion part 1231 and the second expansion part 1232 have simple structures, and are beneficial to the use of the clamping block 123, thereby prolonging the service life of the expansion mechanism 120.
Alternatively, the adjustment lever 122 and the adjustment aperture 124 may be mated by a plug-in interference fit, a screw fit, a snap fit, or other mating means.
Specifically, referring to fig. 3 and 4, the adjusting rod 122 is provided with external threads, the adjusting hole 124 is provided with internal threads, and the adjusting rod 122 is in threaded connection with the adjusting hole 124. In this way, the adjusting rod 122 can be in threaded engagement with the adjusting hole 124 by rotating the adjusting rod 122, which is favorable for improving the convenience and service life of the adjusting rod 122, and further improving the installation efficiency of the drainage wire 300 crimping plate on the tension-resistant drainage yoke plate 200.
Further, referring to fig. 3 and 4, the first expansion part 1231 and the second expansion part 1232 are both wedge-shaped structures. Thus, the first and second expansion portions 1231 and 1232 can be conveniently inserted into the grooves of the tension-resistant drainage yoke plate 200 with different sizes, and the convenience in use of the expansion mechanism 120 can be improved.
Further, referring to fig. 3 and 4, an end of the adjusting rod 122, which is relatively close to the first hole section 1241 and the second hole section 1242, is provided with a tapered portion 1221. The diameter of the tapered portion 1221 gradually decreases in the height direction of the adjustment lever 122, and the tapered portion 1221 is press-fitted with the second hole section 1242. Thus, one end of the tapered portion 1221 can improve the convenience and smoothness of movement of the adjustment member in the adjustment hole 124, reduce the running resistance of the adjustment rod 122 in the adjustment hole 124, reduce the wear of the threads, and further improve the overall quality and service life of the expansion mechanism 120.
The height direction of the adjusting rod 122 is the same as the height direction of the expanding body 121, and is indicated by any arrow on the straight line S 1 in fig. 3.
