Swinging arm type electric lifting wire pay-off device

Abstract

The invention relates to a swinging arm type electric lifting wire pay-off device. The device comprises a lower frame at bottom, wherein a transversely movable supporting plate is arranged in the lower frame, and an upper frame is arranged above the lower frame; the upper frame is a U-shaped structure composed of one transverse square tube and two vertical square tubes which are connected together, and the lower frame is provided with a pivot bracket; the upper end of the pivot bracket is hinged with the middle part of the upper frame, and an up-and-down rotating device for driving the end of the upper frame to lift is arranged between the transverse square tube of the upper frame and the lower frame; one vertical square tube of the upper frame is provided with a main shaft, the front end of the main shaft is provided with a fixed tip cone, the main shaft is connected with a wire pay-off tension device and provided with an electromagnetic brake, and the other vertical square tube of the upper frame is provided with a movable tip cone and a manual rotating disk for driving the movable tip cone to stretch at a corresponding position of the main shaft; a rotary drum is arranged over the upper frame, and the rotary drum is connected with the upper frame through a bracket. The swinging arm type electric lifting wire pay-off device is suitable for paying off the wire for a wire coil.

Description

technical field [0001] The invention relates to a swing arm type electric lifting and unwinding device for unwinding electric wires and cables. Background technique [0002] The currently used pay-off device has a structure such as Figure 5 , Figure 6 , Figure 7 shown. When it works, remove the reel mandrel 1 and the brake disc 2, put the reel mandrel 1 through the center hole of the reel 3, and connect the two ends of the reel 3 with the fixed top cone 4 and the movable top cone 5. Fix it, and then roll the reel 3 up to the top along the inclined wall of the frame 6. At this time, the reel 3 is suspended on the frame 6 through the mandrel 1 of the reel, and then the mandrel 1 of the reel is fixed with the Torx screw 7. Relatively fixed, so that the wire reel 3 can rotate and not slide laterally, thereby realizing the pay-off; in addition, through the pay-off tension formed between the belt 8 and the brake disc 2, the control of the pay-off speed is realized. The abov...

AI Technical Summary

Problems solved by technology

The above-mentioned pay-off device is only suitable for smaller reels (reels below ?630), when it is necessary to pay off larger reels (reels above ?1250), the center hole of reel 3 is due to the 3 The increase of the diameter increases accordingly, which leads to the thickening of the spool mandrel 1, that is, the weight of the spool mandrel 1 increases, which makes it difficult to clamp the spool 3, and it is difficult for one person to clamp the upper and lower spools 3; In addition, the increase of the wire reel 3 will lead to an increase in the inertia when it is unwound, which will easily lead to the failure of the braking system.
