Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a high-voltage cable laying device. Background Art

[0002] High-voltage cable is a type of power cable, which refers to power cables used to transmit power between 1kv-1000kv and are mostly used in power transmission and distribution. At present, some large factories often need to add high-voltage cables or replace aging high-voltage cables during maintenance or technical improvements. However, since the cables are laid in existing factory buildings, the laying space is small and large mechanical equipment such as cable laying machines cannot be used for laying construction. Therefore, the high-voltage cable is often laid by dragging it manually. When laying high-voltage cables manually, the cables are usually pulled directly from the cable reels. However, due to the large diameter of the high-voltage cable and the weight of each meter, it is not easy to complete the laying of the high-voltage cable without the help of external force and relying solely on the strength of the construction workers themselves.

[0003] In order to improve the above problems, after searching, for example, a high-voltage cable laying device provided by patent application number CN202322298171.4 includes a support tube, and both ends of the support tube are slidably matched with the screw rod, and the screw rod is fixed in the support tube by tightening the nut provided on the screw rod; a first bracket and a second bracket are provided on one side of the support tube, and a second roller is provided at one end of the first bracket and the second bracket away from the support tube, and a first roller is also provided on the support tube; when the screw rods at both ends of the support tube are in contact with the edge of the manhole opening, the first bracket and the second bracket are rotated downward so that the second rollers on the two brackets can extend into the harness pipe connected to the side of the manhole. After the harness passes through the first roller and the second roller in turn, the cable can be guided into the harness pipe on the side of the manhole. Based on this, the problem of wear between the outer wall of the high-voltage cable and the manhole opening during laying can be avoided. At the same time, the two rollers roll with the high-voltage cable to reduce the resistance during cable laying, so as to improve the laying efficiency of the cable.

[0004] Based on the above search, combined with the prior art, it is found that the second roller of the high-voltage cable laying device similar to the above disclosed in the prior art is only supported and limited by the spline, and the supporting effect is poor, and the second roller is subjected to greater pressure from the cable, thereby generating a greater deflection force on the device, which easily causes the device to rotate as a whole, or even to leave the manhole. Therefore, a high-voltage cable laying device is proposed to improve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example: Reference Figure 1-4 The high-voltage cable laying device shown includes a main cross bar 1, a first guide wheel 2, a rotating frame 4 and a second guide wheel 5. The first guide wheel 2 is rotatably sleeved on the middle part of the main cross bar 1, and the second guide wheel 5 is rotatably sleeved on the middle part of the rotating frame 4. A connecting sleeve 3 is fixed to the end of the rotating frame 4, and the connecting sleeve 3 is rotatably sleeved on the main cross bar 1.

[0030] Among them, a vertical rod 6 is vertically installed at the lower end of the main cross bar 1, and a secondary cross bar 7 is horizontally fixed to the lower end of the vertical rod 6. An adjustable auxiliary support frame is installed between the secondary cross bar 7 and the rotating frame 4. Specifically, the adjustable auxiliary support frame includes an arc rod sleeve 8, an arc sleeve rod 9 and a fixed knob 10. One end of the arc rod sleeve 8 is fixed to the secondary cross bar 7, the arc sleeve rod 9 is slidably sleeved on the inner side of the arc rod sleeve 8, and the end of the arc sleeve rod 9 located on the outer side of the arc rod sleeve 8 is fixed to the rotating frame 4. The side end of the arc sleeve rod 9 is equidistantly provided with a plurality of threaded holes along its arc trajectory, and the fixed knob 10 is threaded through the arc rod sleeve 8 and is adapted to any one of the threaded holes on the arc sleeve rod 9.

[0031] The arc rod sleeve 8, the arc sleeve rod 9 and the fixed knob 10 cooperate to adjust the overall curvature of the adjustable auxiliary support frame, thereby adjusting and fixing the rotation angle of the rotating frame 4, and the adjustable auxiliary support frame cooperates with the vertical rod 6 and the secondary cross rod 7 to provide stable support for the second guide wheel 5.

[0032] Among them, both ends of the secondary cross bar 7 are installed with a tightening structure 1, and the tightening structure 1 includes a square column 13. The end of the secondary cross bar 7 is provided with a square groove 701, and the square column 13 is horizontally slidably installed on the inner side of the square groove 701. The secondary cross bar 7 is installed with an adjustment structure for driving the square column 13 to slide back and forth on the inner side of the square groove 701. Specifically, the adjustment structure includes a rotating sleeve 11 and a threaded rod 12. The secondary cross bar 7 is divided into two sections. The rotating sleeve 11 is coaxially installed between the two sections of the secondary cross bar 7. One end of the threaded rod 12 is coaxially fixed to the end of the rotating sleeve 11, and the other end of the threaded rod 12 passes through the secondary cross bar 7 and is threadedly connected to the square column 13.

[0033] The operator manually rotates the rotating sleeve 11, so that the threaded rod 12 rotates synchronously. The rotating threaded rod 12 drives the square column 13 to slide horizontally in the square groove 701, thereby achieving rapid tightening between the square column 13 and the inner wall of the manhole. The square column 13 will not rotate during the tightening process and is not prone to scratching against the inner wall of the manhole, thereby better protecting the end of the square column 13 and the inner wall of the manhole.

[0036] In order to increase the friction between the square column 13 and the stop column 15 and the inner wall of the manhole, thereby improving the stability of the fixation of the device, rubber pads are installed at the ends of the square column 13 and the stop column 15.

[0037] The working principle of the utility model is as follows: the overall curvature of the adjustable auxiliary support frame can be adjusted through the cooperation of the arc rod sleeve 8, the arc sleeve rod 9 and the fixed knob 10, so as to adjust and fix the rotation angle of the rotating frame 4, and the adjustable auxiliary support frame can cooperate with the vertical rod 6 and the secondary cross bar 7 to provide stable support for the second guide wheel 5. The operator manually rotates the rotating sleeve 11, so that the threaded rod 12 rotates synchronously, and the rotating threaded rod 12 drives the square column 13 to slide horizontally in the square groove 701, so as to achieve rapid tightening between the square column 13 and the inner wall of the manhole, and the square column 13 will not rotate during the tightening process, and is not easy to be scratched with the inner wall of the manhole, so as to better protect the end of the square column 13 and the inner wall of the manhole. Through the setting of the connecting rod 14, the support column 15 moves synchronously with the square column 13, so that the square column 13 and the support column 15 are synchronously pressed against the inner wall of the manhole, making the fixing operation more convenient and quick.
