Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 3 shown, a power cable laying device described in an embodiment of the present utility model includes a fixed groove 12; a first support plate 13 is fixedly connected to the middle of the fixed groove 12; a plurality of sleeves 11 are fixedly connected to the bottom of the first support plate 13; a spring 16 is fixedly connected to the inner bottom wall of the sleeve 11; a plurality of limit holes 15 are opened in the middle of the first support plate 13; the position of each limit hole 15 corresponds to the top end of the sleeve 11; a limit rod 1 is slidably connected to the middle of the limit hole 15; the bottom of the limit rod 1 is fixedly connected to the top end of the spring 16; during use, first install the fixed groove 12 into the cable laying groove, and then install the first support plate 13 on the fixed groove 12. At this time, the limit rod 1 will extend upward under the elastic action of the spring 16. At this time, the end of the limit rod 1 is higher than the top surface of the first support plate 13. Then, the cable to be laid can be placed on the top of the first support plate 13. During the placement of the cable, the middle of the cable will contact the top of the limit rod 1. At this time, the bottom of the limit rod 1 presses the spring 16, causing the limit rod 1 to contract into the sleeve 11. Some of the limit rods 1 that do not contact the cable can remain upright, realizing the limitation of the position of the cable and reducing the problem of the cable falling off due to moving towards the end of the first support plate 13; by providing a telescopic limit rod 1 on the top of the first support plate 13, the position of the cable is restricted when the cable is placed and installed, and the stability of the cable on the top of the first support plate 13 is maintained.

[0024] like Figures 1 to 2 As shown, a plurality of telescopic rods 21 are fixedly connected to the side wall of the first support plate 13; a first hinge seat 22 is fixedly connected to the end of the telescopic rod 21; a second hinge seat 23 is fixedly connected to the side wall of the limit rod 1; a connecting rod 2 is hinged between the first hinge seat 22 and the second hinge seat 23; by arranging telescopic rods 21 on both sides of the first support plate 13, when the cable contacts the limit rod 1, the limit rod 1 can be controlled by the second hinge seat 23 to move the connecting rod 2 downward during the process of contraction of the limit rod 1 into the sleeve 11, and at the same time, the connecting rod 2 can expand the telescopic rod 21 outwardly through the first hinge seat 22, and at this time, the end of the telescopic rod 21 contacts the middle of the cable; at this time, after the cable is laid and installed, the contact between the telescopic rod 21 and the cable can achieve additional support for the middle of the cable, thereby reducing the wear problem caused by the cable being placed on the first support plate 13 for a long time.

[0025] like Figure 3 As shown, a support column 31 is fixedly connected to the middle of the telescopic rod 21; a second support plate 3 is fixedly connected to the top of the support column 31. By means of the second support plate 3 fixedly connected to the top of the support column 31, when the cable is being laid and installed, the telescopic rod 21 is in the process of being unfolded, so that the cable is in contact with the second support plate 3, thereby increasing the supported area of ​​the cable and reducing the wear caused by the direct contact between the end of the telescopic rod 21 and the cable. The cable is further supported at multiple points, thereby reducing the excessive bending amplitude caused by the cable sagging due to its own gravity when being laid, and increasing the stability of the cable on the second support plate 3.

[0026] like Figure 4 As shown, an articulated frame 42 is fixedly connected to the end of the first support plate 13; a third support plate 43 is hingedly connected to the middle of the articulated frame 42; a second support plate 4 is provided in the middle of the third support plate 43; a through hole 44 is opened in the middle of the third support plate 43 and the second support plate 4; a limited distance nut 41 is installed on the through holes 44 on the second support plate 4 and the third support plate 43; when in use, the third support plate 43 is aligned with the through holes 44 on the second support plate 4, and the limited distance nut 41 is installed on the through holes 44, and the angles of the second support plate 4 and the third support plate 43 on the articulated frame 42 are adjusted, so that the bottom of the second support plate 4 can be supported on the wall or the ground, thereby increasing the force points of the first support plate 13, reducing the shaking of the cable rack, and increasing the additional support and stability of the cable rack.

[0027] like Figure 4 As shown, a desiccant box 5 is fixedly connected to the side wall of the second support plate 4; a plurality of desiccant boxes 5 are arranged on the second support plate 4. When in use, the desiccant box 5 is filled with desiccant, which can reduce the humidity of the space where the cable is located and reduce the aging damage of the cable caused by humidity problems; at the same time, it can reduce the oxidation and rusting problems of the fixing groove 12 and the first support plate 13 caused by humid air.

[0028] As Figure 5 shown, a first support piece 6 is provided at the top of the limit rod 1; the first support piece 6 is arc-shaped; the two end portions of the first support piece 6 are upwardly arranged; when laying and installing the cable, the cable is laid on the first support piece 6, and the arc-shaped arrangement can reduce the situation of the cable slipping off.

[0029] Working principle: First, install the fixing groove 12 into the cable laying groove, and then install the first support plate 13 on the fixing groove 12. At this time, the limit rod 1 will extend upward under the elastic action of the spring 16. At this time, the end of the limit rod 1 is higher than the top surface of the first support plate 13. Then, the cable to be laid can be erected on the top of the first support plate 13. During the placement of the cable, the middle part of the cable will contact the top of the limit rod 1. At this time, the bottom of the limit rod 1 presses the spring 16, causing the limit rod 1 to contract into the sleeve 11. Some of the limit rods 1 that are not in contact with the cable can remain upright, realizing the limitation of the cable position and reducing the problem of the cable moving toward the end of the first support plate 13 and falling off; by providing telescopic rods 21 on both sides of the first support plate 13, when the cable contacts the limit rod 1 and the limit rod 1 contracts into the sleeve 11, the limit rod 1 can control the connecting rod 2 to move downward through the second hinge seat 23. At the same time, the connecting rod 2 can expand the telescopic rod 21 outward through the first hinge seat 22. At this time, the end of the telescopic rod 21 contacts the middle part of the cable; by the second support piece 3 fixedly connected to the top of the support column 31, the cable can contact the second support piece 3 during laying and installation; when in use, align the third support plate 43 with the through hole 44 on the second support plate 4, and install a distance-limiting nut 41 on the through hole 44; adjusting the angle of the hinge frame 42 can make the bottom of the second support plate 4 support on the wall or the ground; when in use, fill the desiccant box 5 with desiccant; when laying and installing the cable, the cable is laid on the first support piece 6.
