Abstract

The utility model discloses a combined slip-ring cable reel, belonging to cable installation devices, which is characterized in that: a flange is fixedly arranged by keys on the right end section of the hollow shaft of the mainframe; through holes are arranged evenly around the circumference of the flange; a double-thread screw is arranged respectively on all through holes; an insulating tube is sleeved on the screw body of each double-thread screw; corresponding to the positions of the through holes in the flange, through holes are arranged around the circumference of the flaky slip ring; all the flaky slip rings are sleeved on all insulating tubes correspondingly from left to right; an insulating spacer sleeve is arranged between each two adjacent flaky slip rings; the nuts on the double-thread screw are screwed to fixedly arrange the flaky slip rings on the right end section of the hollow shaft. The combined slip-ring cable reel has the advantages that: the length of the hollow shaft of the mainframe does not change; the mainframe is suitable for mass production; the quantity, the size and the volume of the flaky slip rings can be changed accordingly with optimized matching, effectively reducing the weight of the whole machine, decreasing production cost and increasing the generality and the work efficiency of the mainframe.

Description

Combination sliding ring type cable drum

Technical field

The utility model belongs to the folding and unfolding cable unit, especially relates to a kind of cable drum of constant force square.

Background technology

The existing cable reel, the output shaft of main frame is a hollow shaft, on an end section of stretching out of hollow shaft, reel is installed, the slip ring of armature portion is installed on the section of stretching out of the other end of hollow shaft, received, the feed cable of putting is fixedly connected on the reel after passing hollow shaft, existing slip ring is the single-casting made from insulating material, whole slip ring is sleeved on key on the section of stretching out of hollow shaft, a kind of cable drum of model, and the length of its hollow shaft section of stretching out is limit by the quantity of slip ring, the quantity of slip ring is many more, hollow shaft stretch out Duan Yuechang, weight is heavy more, processing capacity is big, production cost is high more, simultaneously, a kind of cable drum of model, the quantity of its slip ring is relatively-stationary, the quantity of slip ring, size and capacity can not have been placed restrictions on the versatility of cable drum because of user's demand random fluctuation.

Summary of the invention

The purpose of this utility model provides a kind of combination sliding ring type cable drum, the host machine part and the armature portion of cable drum are separately made, make the main frame batch process of can finalizing the design, more possess versatility, simultaneously, a kind of cable drum of model, but the quantity of its slip ring, size and capacity optimization of matching, random fluctuation as required reduces cost, easy to use and reliable, high efficiency.

The purpose of this utility model is achieved like this: a kind of combination sliding ring type cable drum, comprise reel, main frame, hollow shaft, slip ring, brush holder, brush, gear drive in the motor driven main frame on the main frame drives the hollow shaft rotation, on the overhanging left end section of hollow shaft, reel is installed, received, the feed cable of putting is fixedly connected on the reel after passing hollow shaft, along with reel just, derotation transfers to receive, put, it is characterized in that right-hand member Duan Shangyong key fixed installation flange dish at the hollow shaft of main frame, circumference uniform distribution is offered through hole on ring flange, in each through hole, all install double threaded screw, suit insulated tube on the shaft of each double threaded screw, position corresponding to the through hole of ring flange, circumference uniform distribution is offered through hole on the slip ring of sheet, with the slip ring of each sheet from left to right successively correspondence be installed on each insulated tube, the spacer of insulation is installed between the slip ring of adjacent in twos sheet, the quantity and the size of the slip ring of sheet are distributed rationally as required, after suit finishes, tighten the nut at two ends on the double threaded screw, just the slip ring with each sheet is fixedly mounted on the right-hand member section of hollow shaft, brush is installed on brush holder, each brush is done sliding contact and operate as normal corresponding to the slip ring of each sheet, the length of the hollow shaft of main frame is constant like this, the main frame batch process of can finalizing the design, and the quantity of the slip ring of sheet, size and capacity optimization of matching and random fluctuation as required, alleviated complete machine weight effectively, reduce production cost, increased the versatility and the operating efficiency of main frame.

The combination sliding ring type cable drum that the utility model proposed is rational in infrastructure, safe and reliable, and not only in light weight, cost is low, and possesses good versatility, high efficiency.

Now the combination sliding ring type cable drum of in conjunction with the accompanying drawings and embodiments the utility model being carried is further described.
