The lifting mechanism 110 includes a first fixing member 111, a second fixing member 112 and a lifting assembly 113, wherein the first fixing member 111 is connected to the second fixing member 112 via the lifting assembly 113.

The expanding mechanism 120 includes an expanding body 121, an adjusting rod 122 and a latch 123, and the expanding body 121 is connected to the latch 123. The expanding mechanism 120 is provided with an adjusting hole 124 penetrating through the expanding body 121 and the latch 123, the adjusting rod 122 is in interference fit with the inner wall of the adjusting hole 124, and the adjusting rod 122 can move along the height direction of the expanding body 121. The fixture 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 fixture block 123 to deform, so that the tension-resistant drainage yoke plate 200 is expanded.
In the use process of the tension drainage yoke plate mounting device 100, firstly, the first fixing piece 111 on the lifting mechanism 110 is connected with the tension drainage yoke plate 200, the second fixing piece 112 is connected with the drainage wire 300, and then, the lifting assembly 113 is adjusted to enable the second fixing piece 112 to move close to the first fixing piece 111, so that the bolt at the connecting part of the tension drainage yoke plate 200 is not stressed; then, the fixture block 123 of the expansion mechanism 120 is inserted into the gap of the tension drainage yoke plate 200, the adjusting rod 122 is operated, so that the adjusting rod 122 moves in the expanding body 121 close to the latch 123 to drive the latch 123 to deform and expand, thereby expanding the strain drainage yoke plate 200, and at this time, as the drainage wire 300 is lifted, the connecting part is not pulled, the worker can easily disassemble the bolt, and, because the clamping block 123 props up the tension drainage yoke plate 200, the drainage compression joint plate and the tension drainage plate are loosened, the compression joint plate of the drainage wire 300 can be freely pulled out and restored, and then be favorable to improving the installation and the dismantlement efficiency of drainage wire 300 crimping board, need not to beat drainage wire 300 crimping board and strain drainage yoke plate 200, avoid drainage wire 300 crimping board and strain drainage yoke plate 200 to be beaten and warp, be favorable to improving the life of drainage wire 300 crimping board and drainage yoke plate.
In order to further understand and explain the height direction of the expanding body 121, taking fig. 3 as an example, the height direction of the expanding body 121 is the straight line S in fig. 31In the direction indicated by any of the above arrows.
It should be noted that, the adjusting rod 122 is used for driving the clamping block 123 to deform, so that the strain drainage yoke plate 200 is opened, and it should be understood that the strain drainage yoke plate 200 is U-shaped, and the adjusting rod 122 drives the clamping block 123 to deform, and the strain drainage yoke plate 200 is opened, so that the gap of the U-shaped groove is increased, and the opening mode is in the range that the strain drainage yoke plate 200 can bear deformation, and the strain drainage yoke plate 200 cannot be permanently deformed and cracked.
In one embodiment, referring to fig. 3 and fig. 4, the adjusting hole 124 includes a first hole segment 1241 and a second hole segment 1242. The first hole section 1241 is disposed in the expansion body 121, the second hole is disposed in the fixture block 123, and the inner diameter of at least one section of the second hole section 1242 decreases gradually from the connection portion to the bottom end of the fixture block 123 along the height direction of the expansion body 121. Therefore, in the process that the adjusting rod 122 moves in the adjusting hole 124, because the inner diameter of the second hole section 1242 is gradually reduced, the adjusting rod 122 continues to move downwards to press against the inner wall of the second hole section 1242, so that the adjusting rod 122 props up the fixture block 123 to deform, and props up the U-shaped groove of the U-shaped strain drainage connecting plate 200. When the adjusting rod 122 moves upward, the adjusting rod 122 releases the pressing action on the second hole section 1242, so that the fixture block 123 recovers the original shape under the pressure action or the self elastic action of the tension drainage yoke plate 200, and can be taken out from the U-shaped groove.
Optionally, the deformation of the fixture block 123 may be realized by connecting the fixture block 123 to the expansion body 121, and the adjusting rod 122 drives the fixture block 123 to elastically deform, or by movably connecting the fixture block 123 to the expansion body 121, and the adjusting rod 122 drives the fixture block 123 to move, so as to deform.
In an embodiment, referring to fig. 3 and 4, the latch 123 is rotatably connected to an end of the expansion body 121 far from the end into which the adjusting rod 122 extends, and when the adjusting rod 122 is in interference fit with an inner wall of the second hole section 1242, the latch 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 drainage link plate 200 is opened. When the adjusting rod 122 moves upwards, the shape of the U-shaped groove is restored, so that the clamping blocks 123 move close to each other, and the original shape is restored. The fixture 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 fastening block 123 includes a first expanding portion 1231 and a second expanding portion 1232, and the first expanding portion 1231 and the second expanding portion 1232 are respectively disposed at two opposite ends of the central axis of the second hole section 1242. When the first expansion part 1231 and the second expansion part 1232 are closed, a second hole section 1242 is formed, and the first expansion part 1231 and the second expansion part 1232 are both rotatably connected to the expansion body 121. So, when the adjusting rod 122 downwardly extends into the second hole section 1242, because the inner diameter of the second hole section 1242 is continuously reduced, the adjusting rod 122 struts the first expansion part 1231 and the second expansion part 1232, thereby struts the U-shaped groove of the tension drainage connecting plate 200. When the adjusting rod 122 moves upward and away from the second hole 1242, the U-shaped groove recovers its shape, so that the first and second expanding portions 1231 and 1232 are close to each other, and the original shape of the locking block 123 is recovered. The split-type first expansion part 1231 and the second expansion part 1232 are simple in structure, and are beneficial to the use of the clamping block 123, so that the service life of the expansion mechanism 120 is prolonged.

Thus, the one end of the tapered portion 1221 can improve the convenience and smoothness of the movement of the adjusting member in the adjusting hole 124, reduce the running resistance of the adjusting rod 122 in the adjusting hole 124, reduce the wear degree of the threads, and further improve the overall quality and the service life of the expanding mechanism 120.
Wherein, the height direction of the adjusting rod 122 is the same as the height direction of the expanding body 121, and is the straight line S in fig. 31In the direction indicated by any of the above arrows.
