Description

Technical Field

[0001] The utility model belongs to the technical field of suspension devices, and particularly relates to a temporary cable overhead suspension device for construction sites. Background Art

[0002] In a construction site, devices such as a primary distribution box, a secondary distribution box, a tertiary distribution box, and electrical equipment are set in a temporary power distribution system. The cables from the secondary distribution box to the tertiary distribution box and from the tertiary distribution box to the electrical equipment are mostly mobile cables. The Temporary Electrical Safety Technical Code requires that temporary electricity be installed overhead or buried, and mobile cables are preferably installed overhead.

[0003] When mobile cables are installed overhead, they are mostly supported by square timbers or directly tied to places such as scaffolding and steel bars, which poses certain safety hazards. There are also cases where the bottom end of a support rod is inserted into the ground, and the top end of the support rod uses a support plate and an insulator 4 to support the cable. However, the above methods lack restrictions on the cable, and the cable is likely to fall off. Of course, in the prior art, there are also methods of fixing cables with clips. Although it can prevent the cable from falling off, since the cable is fixed, it has no room for movement and is easily damaged and strained when subjected to external forces. Summary of the Utility Model

[0004] In view of the above technical problems, the utility model provides a temporary cable overhead suspension device for construction sites. The device can prevent the cable from falling off and, after being subjected to external forces, enables the cable to have room for movement and avoid being damaged.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0014] The hook member includes a fixing ring and a hook body; the fixing ring is inserted into the limiting rod, and the hook body is rotatably connected to the fixing ring.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Specific embodiments

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] As Figures 1-6 shown, a temporary cable overhead suspension device at a construction site includes a supporting vertical rod 1 and a connecting cross rod 2. The supporting vertical rod 1 mainly plays a supporting role and can be fixed on the ground as needed. For example, it can be fixed on the steel bars (column head steel bars) at the construction site.

[0027] The connecting cross rod 2 is slidably connected to the upper part of the supporting vertical rod 1. A corresponding chute 3 is provided on the upper part of the supporting vertical rod 1, and a spring 5 is provided between the connecting cross rod 2 and the supporting vertical rod 1; the connecting cross rod 2 can move along the chute 3, and the spring 5 will be compressed when the connecting cross rod 2 moves downward.

[0028] Insulators 4 are fixedly connected to both ends of the connecting cross rod 2; limiting plates 6 are fixed to both ends of the connecting cross rod 2, and a limiting rod 7 that contacts the limiting plate 6 is rotatably connected to the upper end of the supporting vertical rod 1.

[0029] During installation, first fix the supporting vertical rod 1 at the required position; then rotate the limiting rod 7 (in a cross shape with the connecting cross rod 2) so that the limiting rod 7 does not contact the limiting plate 6, and then the cable can be placed on the insulator 4; finally, rotate the limiting rod 7 in the reverse direction (parallel to the connecting cross rod 2) so that the limiting rod 7 contacts the limiting plate 6, thereby blocking the cable and preventing the cable from falling off.

[0030] When the cable is pulled downward by an external force, it will drive the connecting cross rod 2 to move downward along the chute 3, that is, the cable can have a certain movement space after being pulled downward by an external force, thereby avoiding cable damage.

[0031] Further, the limiting rod 7 is preferably a round rod; an arc groove 8 that cooperates with the limiting rod 7 is provided on the limiting plate 6. When the limiting rod 7 is rotated in the reverse direction (parallel to the connecting cross rod 2), both ends of the limiting rod 7 can be inserted into the corresponding arc grooves. Through the structural setting of the arc groove 8, a certain resistance can be provided when the limiting rod 7 rotates, thereby preventing the cable from moving randomly after being placed.

[0032] Furthermore, a slider 9 slidably connected to the chute 3 is fixed to the middle of the connecting cross bar 2; a positioning post 10 is fixed to the slider 9, and a positioning groove 11 is provided at the bottom of the chute 3; the lower end of the spring 5 can be inserted into the positioning groove 11, and the positioning post 10 can be inserted into the upper end of the spring 5.

[0033] Furthermore, various structures can be adopted to fix the supporting vertical rod 1; when there are column head steel bars at the construction site, the connecting hole 12 at the bottom of the supporting vertical rod 1 can be inserted into the column head steel bar. Then it can be fixed through the fastener 13.

[0034] Furthermore, the fastener 13 includes a screw rod 14 and a handle 15. The screw rod 14 is threadedly connected to the supporting vertical rod 1. One end of the screw rod 14 can extend into the connecting hole 12, and the other end of the screw rod 14 is fixedly connected to the handle 15. After the connecting hole 12 at the bottom of the supporting vertical rod 1 is inserted into the column head steel bar, by tightening the screw rod 14, one end of the screw rod 14 extends into the connecting hole 12 and abuts against the column head steel bar.

[0035] Furthermore, legs 16 can be provided at the bottom of the supporting vertical rod 1, and there are at least three legs 16. That is, the device can be directly placed on the ground according to needs.

[0036] Furthermore, the supporting vertical rod 1 is composed of two upper and lower parts, specifically an upper connecting rod 17 and a lower connecting rod 18, and the upper connecting rod 17 and the lower connecting rod 18 are threadedly connected. With this structural setting, after use, the two parts can be disassembled, thereby shortening the overall length and facilitating storage.

[0037] Furthermore, hooks 19 are detachably connected to both ends of the limiting rod 7, and the hooks 19 can hang water pipes, etc. according to needs.

[0038] Furthermore, the hook 19 includes a fixing ring 20 and a hook body 21; the fixing ring 20 is inserted into the limiting rod 7, and the hook body 21 is rotatably connected to the fixing ring 20.
