Description

Technical Field

[0001] The utility model relates to the technical field of cable supports, in particular to a cable installation and adjustment rack for electric power engineering construction. Background Art

[0002] A cable rack is a rack used to support cables. It is usually installed in cable trenches, tunnels, pipe galleries, etc. It can arrange cables neatly, avoid cable crossing and twisting, reduce cable wear and damage, and facilitate cable installation, maintenance and inspection.

[0003] There are many types of cable brackets, the most common ones are angle steel brackets, prefabricated brackets, fiberglass brackets, etc. When these brackets are in use, the cables directly contact the bracket surface. During the cable installation process, the cables need to be dragged and moved to adjust the cable position. The cables that are in direct contact with the bracket surface will generate greater friction with the bracket when moving, which will not only cause great resistance to cable movement and increase the difficulty of cable installation, but also cause scratches on the cable surface. Based on this, a cable installation and adjustment bracket is provided for power engineering construction. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4 In an embodiment of the present invention, a cable installation and adjustment frame for power engineering construction includes a bracket body 1 composed of a mounting plate 101 and a support frame 102. The support frame 102 is fixed to one end of the mounting plate 101. A movable rotation groove 103 and a movable rotation groove 104 are sequentially opened on the top of the support frame 102 in a horizontal direction away from the mounting plate 101. A flip groove 106 is opened at the bottom of the end of the support frame 102 away from the mounting plate 101. A support assembly 2 is provided inside the movable rotation groove 103, the movable rotation groove 104, and the flip groove 106. The support assembly 2 includes a movable support unit, a limit clamping unit, and a locking unit.

[0028] The mobile support unit is used to provide rolling support and guidance for the movement of the cable, thereby reducing the movement resistance of the cable and reducing cable friction;

[0029] The limit clamping unit is used to clamp and fix the cable when it is closed, and the locking unit is used to position and lock the movable support unit when the limit clamping unit is closed;

[0030] The mobile support unit includes a mobile guide wheel 201 and a rotating shaft 202;

[0031] The movable guide wheel 201 is distributed inside the movable rotating groove 103, and the rotating shaft 202 passes through the movable guide wheel 201 and the inner wall end surface of the movable rotating groove 103. The movable guide wheel 201 is fixedly connected to the rotating shaft 202, and the rotating shaft 202 is rotatably connected to the support frame 102;

[0032] The top of the movable guide wheel 201 protrudes from the upper surface of the support frame 102 to provide support for the placement of the cable. At the same time, the rotation of the movable guide wheel 201 when the cable moves is used to reduce the cable movement resistance and friction damage;

[0033] The position limiting clamping unit includes an L-shaped clamping arm 204, a connecting shaft 205, an arc-shaped groove 206, and a fastening hole 208;

[0034] The L-shaped clamping arm 204 is rotatably connected to the inner side of the flip groove 106 via the connecting shaft 205. The flip groove 106 is used to provide space for the flipping of the L-shaped clamping arm 204. The longitudinal portion of the L-shaped clamping arm 204 flips to the top of the movable guide wheel 201 to achieve cable clamping.

[0035] An arc-shaped groove 206 is formed at the bottom of the longitudinal portion of the L-shaped clamping arm 204 to match the outer wall of the cable;

[0036] A fastening hole 208 is formed at one end of the vertical portion of the L-shaped clamping arm 204 and passes through the other end of the vertical portion. A threaded hole 105 is formed at the end of the support frame 102 away from the mounting plate 101. When the vertical portion of the L-shaped clamping arm 204 is in an upward vertical position, the fastening hole 208 is aligned with the threaded hole 105. A bolt passes through the fastening hole 208 and is threadedly connected to the threaded hole 105 to achieve the fixation of the L-shaped clamping arm 204.

[0037] The locking unit includes a self-locking gear 203 and a locking tooth 207;

[0038] One end of the rotating shaft 202 passes through the inner side of the movable rotating groove 104 and is fixedly connected to the self-locking gear 203. The self-locking gear 203 protrudes above the supporting frame 102.

[0039] The locking tooth 207 is formed at the bottom of the longitudinal part of the L-shaped clamping arm 204. When the longitudinal part of the L-shaped clamping arm 204 is flipped to the top of the movable guide wheel 201, the locking tooth 207 is engaged with the top of the self-locking gear 203 to achieve rotation locking of the movable guide wheel 201.

[0040] In this embodiment: It should be supplemented that: the mounting plate 101 is provided with mounting holes for use with expansion bolts for installation in cable trenches, tunnels, pipe galleries, etc.;

[0041] When laying the cable, the cable can be placed on the surface of the movable guide wheel 201 (at this time, the L-shaped clamping arm 204 is in an open state, such as Figure 2 ), so that when the cable is pulled, the rotation of the movable guide wheel 201 can effectively reduce the cable movement resistance and avoid friction between the cable and the support frame 102, thereby reducing friction damage to the cable;

[0042] After the cable is laid, the L-shaped clamping arm 204 can be rotated and flipped around the connecting shaft 205. Finally, the vertical portion of the L-shaped clamping arm 204 is attached to the front end of the support frame 102, and the longitudinal portion of the L-shaped clamping arm 204 is pressed against the surface of the cable through the arc-shaped groove 206. At this time, the fastening hole 208 is aligned with the threaded hole 105. After that, a bolt is passed through the fastening hole 208 and screwed into the threaded hole 105 to tighten it, thereby achieving the fixation of the L-shaped clamping arm 204 and the clamping and fixing of the cable.

[0043] At the same time, when the L-shaped clamping arm 204 completes the clamping of the cable, the locking tooth 207 engages with the self-locking gear 203 to lock the self-locking gear 203. At this time, the movable guide wheel 201 cannot rotate, further improving the stability of the cable.

[0044] Please refer to Figures 1 to 4 There are multiple movable grooves 103 and movable grooves 104 evenly arranged in the horizontal direction and staggered distribution, and there are multiple movable guide wheels 201, rotating shafts 202, self-locking gears 203, and locking teeth 207 correspondingly arranged.

[0045] In this embodiment: this structure can realize the support and movement guidance of multiple cables without interference between the multiple cables;

[0046] It should also be noted that: when the L-shaped clamping arm 204 flips to drive the locking tooth 207 to engage with the self-locking gear 203, if the self-locking gear 203 and the locking tooth 207 are misaligned, the cable can be slightly lifted to fine-tune the self-locking gear 203.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
