[0002] Temporary cable racks for construction are common equipment used to ensure power supply and safety at construction sites. At construction sites, ground operations are frequent and the movement of heavy machinery and equipment may cause damage to cables laid on the ground. By using overhead cables, this damage caused by improper mechanical operation can be avoided.

[0003] For example, a Chinese utility model patent with publication number: CN212849670U discloses a temporary cable installation bracket for construction, including a base, a support rod and an installation top frame. A mounting sleeve is fixedly connected at the center of the base surface, and the mounting sleeve is embedded in the interior of the base. The support rod is longitudinally plug-in connected in the installation sleeve. The support rod is composed of multiple short sleeves and fixing pins. The short sleeves are slidably connected to each other. A threaded fixing pin is provided at the top connection of the short sleeve. The top of the support rod is fixedly connected with the installation top frame. The installation top frame includes a bottom plate, a wire pressing plate and a limit rod. The left end of the bottom plate is welded to the support rod. The wire pressing plate is located on the upper surface of the bottom plate and is fixedly connected to the support rod. The utility model provides an installation sleeve and a fixing buckle connected in a snap-fit ​​manner on the surface of the base, which cooperates with a support rod with multiple sleeve connections, so that the support rod can be easily installed and fixed, and the height of the support rod can be easily adjusted, so that the cable can be easily installed. By providing a base frame and a wire pressing plate on the top of the support rod, the cables can be easily fixed and arranged, thereby improving the convenience of cable installation.

[0004] In the above technical solution, a base frame and a wire pressing plate are provided on the top of the support rod to facilitate the fixing and arrangement of the cables.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 4The utility model provides a technical solution: a temporary cable installation support for construction, comprising: a cross base 1 and a lifting telescopic rod 2, a lifting telescopic rod 2 is provided at the top center of the cross base 1, a rotating sleeve 5 is provided at the top of the lifting telescopic rod 2, an arc bottom plate 10 is fixed on the top of the rotating sleeve 5, baffles 6 are provided on both sides of the arc bottom plate 10, rollers 7 are provided between the baffles 6, there are several rollers 7, and the several rollers 7 are arranged at equal intervals in an arc shape with high top and low sides. The cable is placed above the support roller 13 and the roller 7, and the support roller 13 and the roller 7 are connected by rotation, so that when the cable is dragged, the static friction between the cable and the support can be converted into sliding friction, which can reduce the wear of the cable caused by dragging. In order to further reduce the damage to the cable, the outer walls of the roller 7, the support roller 13 and the pressure roller 16 are all made of soft rubber.

[0022] A push rod 8 is rotatably provided at the center of the top of the baffle 6 on one side, and a clamping seat 9 is provided at the center of the top of the baffle 6 on the other side. A C-shaped clamping groove opening upward is provided inside the clamping seat 9, and the clamping seat 9 is used for clamping one end of the push rod 8. By rotating the push rod 8, one end of the push rod 8 is clamped in the clamping seat 9, and the push rod 8 blocks the top of the roller 7 to prevent the cable from escaping from the bracket.

[0023] The top surface of the arc bottom plate 10 is in an arc shape with a high middle and low sides. This design makes it easy for dust on the cable to fall off quickly after falling on the arc bottom plate 10, thus avoiding dust accumulation.

[0024] The bottom of the arc bottom plate 10 is a plane, and elastic telescopic rods 11 are arranged on both sides of the bottom of the arc bottom plate 10. A U-shaped fixed seat 12 is arranged at one end of the elastic telescopic rod 11. A slide groove 14 is opened inside the U-shaped fixed seat 12 on one side.

The bottom end of the clamping screw 17 is rotatably connected with the top of the slider 15. When the cable is placed on the support roller 13 and the roller 7, the slider 15 is driven to descend by adjusting the clamping screw 17, thereby driving the pressure roller 16 to descend. The cable is clamped by the pressure roller 16 and the support roller 13. When the cable is dragged, the dragging force received by the cable will be transmitted to the elastic telescopic rod 11. The elastic displacement of the elastic telescopic rod 11 buffers the dragging force of the cable, thereby reducing the impact of repeated dragging on the cable.

By loosening the locking screw on the rotating sleeve 5, the angle of the rotating sleeve 5 relative to the lifting telescopic rod 2 can be adjusted, thereby adjusting the installation and extension direction of the cable.

[0028] When the temporary cable erection bracket is used in construction, the cable is placed above the support roller 13 and the roller 7. Through the rotation connection between the support roller 13 and the roller 7, when the cable is dragged, the static friction between the cable and the bracket can be converted into sliding friction, which can reduce the wear of the cable caused by dragging.

[0029] When the cable is temporarily installed, the height of the lifting telescopic rod 2 can be adjusted by tightening the position of the bolt 4 on the piston rod, thereby adjusting the installation height of the cable. By loosening the locking screw on the rotating sleeve 5, the angle of the rotating sleeve 5 relative to the lifting telescopic rod 2 can be adjusted, thereby adjusting the installation extension direction of the cable. After the cable is placed on the supporting roller 13 and the roller 7, the top rod 8 is rotated to clamp one end of the top rod 8 in the clamping seat 9, and the top rod 8 is used to block the top of the roller 7 to prevent the cable from escaping from the bracket. In addition, by adjusting the clamping screw 17, the slider 15 is driven to descend, thereby driving the pressure roller 16 to descend, and the cable is clamped by the pressure roller 16 and the supporting roller 13. When the cable is dragged, the dragging force received by the cable will be transmitted to the elastic telescopic rod 11. The elastic displacement of the elastic telescopic rod 11 buffers the dragging force of the cable, thereby reducing the impact of repeated dragging on the cable.
