[0031] The lifting type cable reel support frame provided by the utility model makes, first, the finished cable reel (for example, the radius of the cable reel used in a certain project is 1.1 meters) is transported to the cable reel designated position in the use site. Second, one support frame of the utility model is placed at the left end of the cable reel, and another support frame of the utility model is placed at the right end of the cable reel, and the two support frames are respectively placed on the ground and stand stably, specifically, the position of the telescopic support column 2 is first determined, if the ground touched by each inclined leg 3 is solid, the support frame can be directly placed; if one inclined leg 3 of the support frame falls in a pit or soft soil position, the support frame is slightly rotated (for example, the inclined leg 3 is moved to the left, and the other inclined leg 3 is moved to the right), and then the support frame is placed on the ground. Figure 6);If a certain inclined leg 3 of the support frame falls on the sand pile position, the inclined leg 3 does not need to be allowed, but is directly inserted into the sand pile, at this time the sand pile does not cause the installation of the support frame to be hindered but can help to maintain the stability of the inclined leg 3. Third, the cable tray is positioned after the two support frames are erected and the support shaft 14 is inserted into the center hole of the cable tray, and then the two ends are placed in the two side grooves 1. Fifth, the position of the groove 1 is lifted by adjusting the telescopic support 2, if one of the support frames is installed on the ground position is lower, increase its length, so that its groove 1 is at the same height with the groove 1 of the support frame on the opposite side.

[0032] On the one hand, the conventional cable tray is rotated by the pulling of the cable end, and the cable tray is rotated on the support shaft 14, and the existing support shaft 14 cannot rotate due to the large friction force between the cable tray and the groove 1, and only supports the function, and the rotation of the cable tray is realized by the pulling force of the cable end. On the other hand, the specifications of the cables used in engineering are different, and the cable trays purchased during engineering have some differences, and the support shaft 14 of the cable tray is different, and the stability of the support shaft 14 of different sizes falls into the same specification groove 1.

[0033] In order to improve the above problems, the embodiment of the groove 1 structure provided by the utility model is: the groove 1 is a U-shaped structure, a plurality of second balls 6 are embedded in the inner wall of the groove 1, a roller shaft 7 is arranged on the inner side of the upper edge of the groove 1, the roller shaft 7 is parallel to the axis of the groove 1, the roller shaft 7 is installed on a roller frame 8, the back side of the roller frame 8 is fixedly connected with a lead screw 9, an adjusting nut 10 and a fixed nut 11 are sleeved on the lead screw 9, the adjusting nut 10 is located on the inner side of the groove 1, and the fixed nut 11 is located on the outer side of the groove 1.

[0034] The second ball 6 structure can reduce the friction between the groove 1 and the support shaft 14, so that the support shaft 14 can also rotate when the cable is pulled, the rotation of the support shaft 14 assists the rotation of the cable tray, thereby saving the output of the cable pulling end; the embodiment of the embodiment can be telescopic roller shaft 7 when the support shaft 14 is a smaller shaft body as a top limit to avoid it from falling out, when the support shaft 14 is a larger shaft body, it serves as a side support and also reduces the rotation resistance.

[0035] Optionally, the embodiment of the telescopic support 2 provided by the utility model is: the telescopic support 2 is composed of a sleeve 201 and a core barrel 202, the lower end of the sleeve 201 is provided with a mounting window 203, the mounting window 203 is provided with a jack 4, and the core barrel 202 is sleeved in the sleeve 201 and falls on the upper end of the jack 4. More specifically, the sleeve 201 and the core barrel 202 are both steel pipes, the top end of the core barrel 202 is welded with an H steel seat 12, the top of the H steel seat 12 is welded with a cover plate 13, and the rotating disc groove 502 and the limiting plate 505 are fixedly connected with the cover plate 13.

[0036] Before lifting the support shaft 14 and the cable tray by the support frame, the jack 4 is placed under the core barrel 202 from the installation window 203, the height of the bracket 1 is controlled by lifting the core barrel 202 by the jack 4, and the height of the bracket 1 on both sides needs to reach a position where the cable tray can rotate freely, and finally the balance of both ends is achieved by fine-tuning the jack 4. The telescopic support column 2 adopts a thickened steel pipe, which has high strength and can bear the support work of a large cable tray. The jack 4 is a conventional tool in engineering, and the installation window 203 facilitates the installation of the jack 4. At the same time, the installation window 203 serves as a manhole for the jack 4, which facilitates the lifting adjustment of the jack 4. The telescopic support column 2 has low cost, high strength and long service life.

[0037] The utility model also proposes the improvement to the support leg structure, and the specific inclined support leg 3 includes the shell 301 and the telescopic core 303, the shell 301 is equipped with the sliding slot 302, is equipped with the connecting column 304 in the sliding slot 302, the connecting column 304 one end is fixedly connected with the telescopic core 303, the other end is connected with the pedal 305, and the pedal 305 is perpendicular to the shell 301 and the telescopic core 303. The shell 301 adopts C-shaped steel beam, and the telescopic core 303 is matched with the inner cavity of the C-shaped steel beam. The gravity of the telescopic core 303 is avoided from falling off by the friction resistance of the contact surface. Of course, a gasket can be arranged on the matching surface to extrude the movement space of the telescopic core 303, so as to increase the friction. When the inclined support leg 3 inevitably falls in the pit or soft soil area, the telescopic core 303 is further stretched out to be inserted into the hard bottom of the pit or the deep part of the soft soil area by pushing down the pedal 305, so that the inclined support leg 3 has the same foundation stability as other inclined support legs 3, and the perpendicularity and stability of the telescopic support column 2 are ensured.

[0038] Further improvement, the outer surface of the support shaft 14 in contact with the center hole of the cable tray is set as a rough surface, and a rotating handle is arranged at the end of the support shaft 14. The cable tray is rotated by the rough surface of the support shaft 14, and the cable tray actively rotates to assist the release of the cable, so as to avoid the cable from being broken or damaged due to stress.

[0039] The utility model has the advantages of:

[0040] 1) The two side supports can control the lifting respectively, and can keep the cable tray horizontal at the position with height difference; 2) The bracket can rotate, and the setting is more convenient without considering the symmetry requirement; 3) The structure without bottom plate can adapt to sandy soil and gravel ground; 4) The inclined support leg structure can further adapt to the pit and soft soil, and can ensure the stability of the cable tray on the complex construction site.

[0041] The above only describes the preferred and feasible embodiment of the utility model, and does not limit the scope of the utility model, and any equivalent changes made according to the content of the utility model specification and the drawings are included in the scope of the utility model.
