Description

Technical Field

[0001] The utility model relates to an electric power engineering cable installation and adjustment frame. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or several groups of wires. It is made of one or more mutually insulated conductors and an outer insulating protective layer, and is used to transmit electricity or information from one place to another. It is usually a rope-like cable made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering.

[0003] With the development of society and the advancement of science and technology, the construction of power projects is increasing, and the installation and adjustment of cables has become an important part of project construction.

[0004] When laying the cable, it is necessary to use a pay-off rack to build at the wellhead of the cable well, then pull one end of the cable out, pass it through the cable well and into the cable pipe, and then pull the cable through the pipe.

[0005] In actual operation, the cable will bend during the process of passing from the ground through the cable well and then into the cable pipe. Due to the traction force, the cable will scratch the corners of the cable well and the cable pipe. This scratch is relatively sharp and can easily cause damage to the cable skin.

[0006] Based on the above problems, we designed an electric power engineering cable installation and adjustment rack which is built at the wellhead of the cable well and allows the cable to pass through the cable pipe without scratching. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide an electric power engineering cable installation and adjustment frame which is built at the wellhead of a cable well and can allow the cable to pass into the cable pipe without scratching.

[0011] Preferably, the adjustable bracket includes an L-shaped bracket plate and a sliding rod installed on the side of the bracket plate. The sliding rod fits in the sliding groove and slides laterally along the sliding groove. A positioning screw is screwed into the side of the outer end surface of the sliding rod away from the bracket plate. The positioning screw penetrates the sliding rod and rests against the bottom of the sliding groove. At this time, the position of the sliding rod is fixed.

[0012] Preferably, the fixed pulley assembly comprises two front and rear vertical plates, the bottoms of the vertical plates are fixed to the frame, an axle is provided between the two vertical plates, and a fixed pulley is rotatably provided on the axle.

[0013] Preferably, the adjustable pulley assembly includes a first shaft rod fixedly mounted on the inner side of the frame, the first shaft rod is arranged on the side away from the fixed pulley, a rotating tube is arranged on the first shaft rod, a first positioning screw is cooperated between the rotating tube and the first shaft rod, two sleeve rods are arranged in parallel on the outer wall of the rotating tube, a movable rod is slidably arranged in the sleeve rods, a second shaft rod is fixedly mounted between the two movable rods, the first fixed pulley is rotatably mounted on the second shaft rod, and a second positioning screw for fixing the movable rod is arranged at the end of the sleeve rod.

[0014] The beneficial effects of the utility model are:

[0015] Advantage 1: The device can be adjusted in lateral width to meet the needs of cable wells of different sizes.

[0016] Advantage two: the extension length of the adjustable pulley assembly is adjustable to meet the adaptation needs of cable wells of different depths.
