Length-width-adjustable quick take-up and pay-off device applicable to different models of cable reels and method for applying length-width-adjustable quick take-up and pay-off device

Abstract

The invention discloses a length-width-adjustable quick take-up and pay-off device applicable to different models of cable reels and a method for applying the length-width-adjustable quick take-up and pay-off device. The length-width-adjustable quick take-up and pay-off device comprises a U-shaped frame. Universal self-locking rollers are arranged at four corners of the U-shaped frame, extension rods which are perpendicular to transverse rods are arranged on the inner sides of free ends of the two transverse rods of the U-shaped frame, connecting rods which are hinged to each other in a crossed manner are arranged at the ends of the extension rods, the other end of each connecting rod is in cup joint with the free end of the other corresponding extension rod in a crossed manner, two cable reel sliding mechanisms sleeve each connecting rod, the length of each extension rod is larger than the width of each cable reel sliding mechanism, guide sleeves sleeve the two transverse rods of the U-shaped frame and are connected with each other by a fixing rod, two driving rollers which are rotationally connected with the fixing rod sleeve the fixing rod, annular grooves are formed in the peripheral sides of the driving rollers, the cable reels can be clamped in the annular grooves, and the center of a side of the fixing rod is connected with the center of a vertical rod of the U-shaped frame by a hydraulic ejector rod.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment used by electricians when erecting power lines, and in particular relates to a quick take-up and release device with adjustable length and width suitable for different types of cable reels and a use method. Background technique [0002] The power line product is a power line reel that winds the power line on the reel. When erecting high-altitude power lines, a large number of power lines are used. The power line reel is large in size and heavy, and the reel must be rotated when the wire is released. In order to use the power line reel to pay out the wires, the power line reel should be placed on the power line pay-off rack when paying out the wires. The power line pay-off frame is mainly used to support the power line reel for easy pay-out. [0003] In the construction of the substation secondary system, the workload of cable laying occupies the main construction time. The curren...

Problems solved by technology

Its shortcoming is that a crane is required to hoist the cable reel on the bracket during use, which is time-consuming and labor-intensive and requires the cooperation of multiple people.

Its shortcoming is that the cable reel needs to be frequently pushed between the rollers of the platform during use, and the staff needs to fix the platform on the ground and ensure that the platforms of the two bases are parallel and orderly so that the cable reel can be pushed smoothly. Between the rollers on the platform, frequent replacement of cable reels of different specifications requires frequent adjustment of the distance between platforms and disassembly and fixing of the platform, which is extremely time-consuming and labor-intensive to use; at the same time, due to the weight of the cable reel, multiple personnel are required to push it In the process of pushing, it is easy to cause the cable reel to fall out and hurt others. Usually, at least 5 workers are required. The push is time-consuming and laborious. It takes at least 3 people to remove the cable reel and replace it with another cable reel of a different type. Hours, the work efficiency is low, and it takes time and effort to pull the wire to rotate
