Portable and adjustable large tonnage cable laying device

Abstract

The invention discloses a convenient, light-weight and adjustable large-tonnage cable laying apparatus. A shaft rod is arranged at the upper ends of two side brackets; the shaft rod is provided with a cable drum; a guiding sleeve is arranged at the upper end of each side bracket separately; a lifting rod is arranged in each guiding sleeve in a sleeving manner; the lower end of each lifting rod is connected with a piston rod of a hydraulic cylinder; the upper end of each lifting rod is connected with the lower end of a bearing support; the shaft rod is provided with two bearings which are placed in upper end grooves of two bearing supports respectively; a brake wheel disc is mounted at one end of the shaft rod; the bake wheel disc is matched with a brake mechanism; the brake mechanism comprises a brake sheet and a screw crank arm; a positioning hoop is arranged on the shaft rod at the other end of the cable drum; and the shaft rod is provided with an arm shifting rod. The convenient, light-weight and adjustable large-tonnage cable laying apparatus is convenient and light-weight in operate; after the bearings and the fixed loop are mounted, the mechanical friction is almost zero; and the drum rotates freely and uniformly without generating noise, so that the problem of left and right swinging of the drum is solved.

Description

Technical field: [0001] The invention relates to a cable laying device, in particular to a portable and adjustable large-tonnage cable laying device. Background technique: [0002] At present, cables are more and more widely used, and the cross-section is getting larger and larger. The diameter of the cable reel is correspondingly increased (4 meters high and 2.8 meters wide), and the average weight of each cable is 20-25 tons. For the cable reel, it is necessary to improve the cable bracket to ensure that the large-tonnage cable remains stable, rotates freely, and is fast and efficient during the casting process. [0003] The cable pay-off device that adopts at present is only a relatively simple column type, and the lead screw lifts the cable reel. During the operation of the cable reel, due to the weight of the reel, the shaft bar will rotate accordingly, which will cause vibration and friction. The whole reel will swing and make harsh noises.

AI Technical Summary

Problems solved by technology

[0003] The cable pay-off device currently used is a relatively simple column type. The screw lifts the cable reel, and the inner cavity of the cable reel is inserted into the shaft bar. It needs manpower and levers to lift up and down, which is slow and laborious.

During the operation of the cable reel, due to the weight of the reel, the shaft bar will rotate accordingly, which will cause vibration and friction, and the whole reel will swing and make harsh noises.
