Description

Technical Field

[0001] The invention relates to the technical field of cable laying, and in particular to a traction device and a traction method for laying cables in an electric power engineering project. Background Art

[0002] As an important branch of electrical engineering, power engineering aims to achieve efficient, safe and reliable supply of electric energy through scientific methods to meet people's electricity needs. During the construction process of power engineering, cable laying and traction devices are often required to lay cables.

[0003] As a component of power electronic devices, cables require traction devices in their manufacturing process. During operation, some existing cable laying traction devices need to move the cable reel for winding up the cable to the cable laying traction device and fix it, and then control the rotation of the cable reel to move the cable from the cable reel for cable laying. When the cable reel is moved to the cable laying traction device for fixing its position, since the cable reel with the wound cable usually has a large weight, it is often necessary to use external lifting equipment (such as a forklift, a crane, etc.) to lift the cable reel and then fix the position of the cable reel, which will increase the construction cost. Summary of the invention

At this time, the U-shaped block will toggle the set block to rotate, and rotate synchronously with the rotating shaft fixedly installed on the set block. The prying plate fixedly installed on the rotating shaft rotates upward synchronously, so that the cable reel is pushed by the prying plate to be lifted to the desired position on the inclined platform for subsequent installation.

[0006] Two guide platforms are arranged on the movable frame, and sliding plates are slidably installed on the two guide platforms, and the top ends of the two sliding plates are commonly connected to a U-shaped frame, a rotating rod is rotatably installed in the U-shaped frame, a mounting frame is fixedly installed on the outer wall of the rotating rod, a groove is arranged on the mounting frame, and a mounting rod is arranged in the groove, a cable drum and two nuts are movably sleeved on the outer wall of the mounting rod, and a second guide wheel is installed on the top end of the mounting frame.

[0014] A traction method for a traction device for laying cables in an electric power engineering project, the method comprising the following steps: Step 1: Move the cable drum to the inclined platform and position it directly above the prying plate, and synchronously control the driving gear to rotate. At this time, the linkage gear plate is driven by the driving gear to move to the right, and drives the plug-in plate, the prying plate, and the U-shaped block to translate. At this time, the U-shaped block will pry the set block to rotate, and rotate synchronously with the rotating shaft fixedly installed on the set block. The prying plate fixedly installed on the rotating shaft rotates upward synchronously, so that the cable drum is pushed by the prying plate to be lifted on the inclined platform to the groove on the mounting frame; Step 2: The mounting rod is passed through the mounting frame and the cable drum, and the nut is rotated on the outer wall of the mounting frame to fit closely to the cable drum, so that the cable drum is fixed on the mounting frame. At this time, the plug-in plate can be pulled out from the linkage tooth plate, and the driving gear is controlled to reverse, so that the linkage tooth plate fits the T-block, and the linkage tooth plate and the T-block are connected into a whole through the I-block. At this time, the plug-in block is located in the opening on the L-shaped mounting frame; Step three: The driving gear rotates again to drive the T-block, plug-in block, L-shaped mounting frame, U-shaped frame, rotating rod, mounting frame, and cable reel to move to the right, and during the movement, the cable reel is gradually raised on the inclined platform. When the sliding plate is in contact with the limit plate, the locking screw passes through the limit plate to connect the sliding plate, thereby fixing the cable reel at this height for use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention controls the rotation of the driving gear so that the pry plate can tilt upward under the drive of the driving gear, so that the cable reel can be lifted to a certain height on the inclined platform and located in a groove on the mounting frame, which is convenient for the cable reel to be installed on the mounting frame for use later and avoids the need to rely on external large equipment to hoist the cable reel to a required height for use.

[0016] By driving the sliding plate to move on the guide platform through the driving gear, the mounting frame on which the cable reel is installed can be further raised on the inclined platform, so as to facilitate the laying of cables at a later stage.

[0017] The locking screw passes through the limit plate and connects the sliding plate, so that after the cable reel is lifted to a desired height for use, the pressure on the driving gear can be relieved, thereby increasing the service life of the driving gear. BRIEF DESCRIPTION OF THE DRAWINGS
