Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Reference Figure 1-5 One embodiment provided by this utility model:

[0023] A cable lifting system includes three independent cable lifting devices. Each cable lifting device includes a drive flatbed 11 and a lifting flatbed 21, which are hinged together. The drive flatbed 11 is equipped with a drive frame 22, a hydraulic station 23, and a control cabinet 24. The lifting flatbed 21 is equipped with a lifting frame 12, a lifting mechanism, a telescopic mechanism, and a wire-feeding pulley 1321. The lifting frame 12 is mounted on the flatbed 11, and the lifting mechanism is rotatably mounted on it. The lifting mechanism is connected to the telescopic mechanism, which enables the lifting of the telescopic mechanism. The wire-feeding pulley 1321 is mounted on the telescopic mechanism, which enables the wire-feeding pulley 1321 to extend and retract in the forward and backward directions. The hydraulic station 23 is used to drive the lifting mechanism and the telescopic mechanism. This solution enables the automatic installation of high-voltage cables. To facilitate this automatic installation, three cable lifting devices are installed at intervals during the installation process. These three devices are positioned along the cable installation direction and close to the installation location. During the installation process, the three cable lifting devices lift the cable at an incline to ensure the stability of the cable lifting.

[0024] In addition, the drive flatbed vehicle 11, lifting flatbed vehicle 21, hydraulic station 23, control cabinet 24, lifting frame 12, lifting mechanism, telescopic mechanism, and wire laying pulley 1321 are all modularly designed. In this way, each module can be transported separately into the tunnel and then assembled for use, which is convenient.

[0025] The telescopic mechanism includes a telescopic front frame 1311, a telescopic bottom frame 1312, a telescopic platform 132, two first scissor arms 1331, two second scissor arms 1332, and corresponding first and second scissor arms are connected by a cross shaft 1333. The end of each first scissor arm 1331 is hinged to the inner top of the telescopic bottom frame 1312, and the other end is connected by a first connecting rod and is provided with a first slider. The telescopic bottom frame 1312 is provided with two first telescopic grooves 1341 along its length, and the first slider is slidably disposed in the second telescopic groove 136 of the telescopic front frame 1311.

[0026] The first scissor fork arm and the second scissor fork arm are basically symmetrical structures. The end of each second scissor fork arm 1332 is hinged to the inner top of the telescopic front frame 1311, and the other end is connected through the second connecting rod 137 and is provided with a second slider 1342. The telescopic front frame 1311 is provided with two second telescopic slide grooves 136 along the length direction. The second slider is slidably disposed in the first telescopic slide groove 1341 of the telescopic bottom frame 1312.

[0027] The fixed end of the hydraulic rod is located on the telescopic base frame 1312, and the second connecting rod is provided with a first connecting piece 135 that is hinged to its piston end;

[0028] The telescopic platform 132 is fixedly equipped with a line-laying pulley 1321 on the front side, and the hydraulic station 23 provides drive for the telescopic hydraulic cylinder 138.

[0029] The lifting mechanism includes a winch 141, a lifting rope 142, a lifting pulley 143, a roller 144, a roller connecting shaft 145, a lifting groove 146, and a hook 148 fixedly connected to the lifting rope 142 on the roller connecting shaft 145. The roller connecting shaft 145 is fixedly connected to the telescopic base frame 1312 through a second connector (not shown). Rollers 144 are provided at both ends of the roller connecting shaft 145. Lifting grooves 146 are symmetrically provided on the inner walls of both sides of the lifting frame 12. The rollers 144 roll in the lifting grooves 146. The lifting pulley 143 is provided at the top of the lifting frame 12. The winch 141 lifts and lowers the telescopic mechanism through the winch's lifting rope 142, lifting pulley 143, and hook 148.

[0030] Since the frame of the device is made of iron and other equipment is heavy, in order to facilitate the movement of the device, the drive flatbed trolley 11 is equipped with two drive wheels 25. The drive wheels 25 are equipped with hydraulic motors 26, which are driven by hydraulic stations 23. Thus, the entire device can move automatically under the control of the controller, saving effort and time.

[0031] Because some of the cables being laid are located in narrow tunnels, the width of the vehicle cannot be too wide. However, the entire device is relatively heavy, and the cables to be laid are large-section cables with significant weight. To improve the stability of the lifting cables, each of the four driven main wheels 112 of the lifting flatbed 21 is connected to a secondary wheel 116 via a telescopic structure. To facilitate the design and operation of the telescopic structure, the telescopic structure adopts the following... Figure 5 The telescopic structure shown includes an adjusting sleeve 113 with an adjusting hole, an adjusting rod 114 with an adjusting hole, and a pin 115. The adjusting sleeve 113 and the adjusting rod 114 are unlocked and locked by the adjusting holes on the pin 115 and the adjusting sleeve 113 and the adjusting rod 114. This not only makes the whole device stable, but also makes it suitable for laying sites of different widths.

[0032] How to use:

[0033] Step 1: Arrange the three cable lifting devices at intervals along the cable laying direction, with the cable lifting device at the front closest to the cable mounting point;

[0034] Step 2: Start the hydraulic station 23 of each cable lifting device to drive the telescopic mechanism and telescopic mechanism to put the cable laying pulley 1321 at the front and lowest positions;

[0035] Step 3: Lift the cable and place it on the cable release pulley 1321 of each cable lifting device;

[0036] Step 4: Start the winch 141 and adjust the height of the three lifting mechanisms so that the cable-laying pulleys 1321 are arranged in a sloping manner to ensure the stability of cable lifting. The cable-laying pulley 1321 at the very front, which is also the one that places the cable at the highest position, is higher than the ground above the cable rack.

[0037] Step 5: Place the cable end on the ground of the rack, first drive the lifting mechanism to descend, and then drive the telescopic mechanism to move the cable release pulley 1321 in the lifting direction, so that the cable is released from the cable release pulley 1321, and the cable mounting operation is completed.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
