Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to an external protective bracket for cable laying. Background Art

[0002] When laying cables in a cable trench, cable brackets are installed to prevent them from falling or being damaged by gravity or other external forces. This also reduces the space occupied by cables and improves the efficiency of cable planning and layout. During actual construction, due to the length of the cables, the cables can rub against the cable brackets during the pulling process, causing damage to the cables and shortening their service life. Existing cable brackets typically consist of horizontal support rods and triangular ribs positioned below them. For these cable brackets, an external protective bracket for cable laying has been designed. Utility Model Content

[0003] The purpose of the utility model is to provide an external protective bracket for cable laying, which can be installed on a cable bracket to provide auxiliary support for the cable and avoid friction between the cable and the cable bracket during the pulling process.

[0004] The utility model is realized by the following measures: an external protective bracket for cable laying, characterized in that it comprises a base, a horizontal roller is provided on the base, and vertical limiting rollers are provided on the base and on both sides of the horizontal roller;

[0005] At both ends of the outer side of the base, one end is fixedly provided with a limiting sleeve that is sleeved on the small end of the horizontal support rod of the cable bracket, and the other end is provided with a U-shaped plate with an opening facing upward; an external vertical plate is fixedly provided on the base, and at least two horizontal limiting columns are fixedly provided on the external vertical plate. The inner side of the U-shaped plate is sleeved on the horizontal limiting column through a guide plate, and the guide plate and the external vertical plate are connected by a spring sleeved on the horizontal limiting column;

[0006] The upper end surfaces of the limiting sleeve and the U-shaped plate are both lower than the upper end of the side wall of the horizontal roller, and the U-shaped plate is provided with a plurality of screws that are pressed against the triangular ribs of the cable bracket through threaded connection.

[0007] The opening width of the U-shaped plate is slightly larger than the width of the horizontal supporting rod.

[0008] In actual use, setting up two vertical limiting rollers may sometimes affect the traction of the cable, so in this case only the vertical limiting roller located on the inner side may be retained.

[0009] It also includes a wedge block arranged in the limiting sleeve to tighten the horizontal supporting rod, or the upper end of the limiting sleeve is provided with a screw that presses on the horizontal supporting rod through a threaded connection.

[0010] The base includes two symmetrically arranged vertical plates, the two ends of the horizontal roller are arranged on the vertical plates, the front and rear sides of the vertical plates are provided with side plates, the upper ends of the two side plates are fixedly connected through a lower horizontal plate, a vertical mounting plate is fixedly provided on the lower horizontal plate, an upper horizontal plate opposite to the lower horizontal plate is provided on the upper end of the mounting plate, and the two ends of the vertical limiting roller are provided on the upper horizontal plate and the lower horizontal plate.

[0011] The horizontal rollers and vertical limiting rollers each include a fixed shaft and a roller rotating on the fixed shaft. The vertical plate, upper horizontal plate and lower horizontal plate are each provided with mounting holes for the fixed shaft. The outer periphery of the roller is wrapped with a rubber protective layer.

[0012] The fixed shaft is fixed by a pin, or the outer end of the fixed shaft is provided with a thread and fixed by a nut. A nut installation opening is reserved between the lower horizontal plate and the vertical plate.

[0013] One of the mounting holes for mounting the vertical limiting roller and the horizontal supporting roller is connected through a rectangular opening that allows the fixed shaft to pass through.

[0014] The lower ends of the two vertical plates are connected through a fixed bottom plate.

[0015] Usage: During installation, pass the U-shaped plate through the small end of the cable bracket until the limit sleeve is connected to the horizontal support rod, then tighten the screws, knock the wedge into the limit sleeve, and lock the limit sleeve. At this time, the bracket is fixed on the cable bracket. Since both the horizontal roller and the vertical limit roller can rotate, the wear caused by friction between the cable and the bracket can be reduced.

[0016] When the bracket needs to be removed, take out the wedge, slightly lift the cable placed on the horizontal roller, and pull the bracket outward. At this time, since the U-shaped plate is fixed to the cable bracket by screws, the spring is stretched and the limit sleeve is separated from the horizontal support rod. After the limit sleeve is separated, loosen the screws. At this time, the bracket can be taken out from under the cable bracket.

[0017] The beneficial effect of the technical solution provided by the embodiment of the present utility model is that the bracket can be installed on the cable bracket to provide auxiliary support for the cable, thereby avoiding friction between the cable and the cable bracket during the traction process.

The U-shaped plate 5 is provided with a plurality of screws 9 that are pressed against the triangular ribs 1302 of the cable bracket 13 through threaded connection.

[0027] In actual use, setting two vertical limiting rollers 3 may sometimes affect the traction of the cable, so in this case, only the vertical limiting roller 3 located on the inner side can be retained.

[0028] It also includes a wedge 10 set in the limiting sleeve 4 to tighten the horizontal support rod 1301, or the upper end of the limiting sleeve 4 is provided with a screw 9 that presses on the horizontal support rod 1301 through a threaded connection.

[0029] The base 1 includes two symmetrically arranged vertical plates 101, and the two ends of the horizontal roller 2 are arranged on the vertical plates 101. Side plates 102 are arranged on the front and rear sides of the vertical plates 101. The upper ends of the two side plates 102 are fixedly connected through a lower horizontal plate 103. A vertical mounting plate 104 is fixedly arranged on the lower horizontal plate 103, and an upper horizontal plate 105 opposite to the lower horizontal plate 103 is arranged on the upper end of the mounting plate. The two ends of the vertical limiting roller 3 are arranged on the upper horizontal plate 105 and the lower horizontal plate 103.

[0030] The horizontal roller 2 and the vertical limiting roller 3 both include a fixed shaft and a roller rotating on the fixed shaft. The vertical plate 101, the upper horizontal plate 105 and the lower horizontal plate 103 are all provided with mounting holes 11 for the fixed shaft; the outer periphery of the roller is wrapped with a rubber protective layer.
