Description

Cable transfering machine

The utility model relates to a kind of cable laying machinery that is used for power transmission and distribution project, particularly a kind of telpher.

For the labour intensity that alleviates cabling with guarantee construction quality, at present domestic 250 kilograms of multiple telphers such as telpher having developed wherein as Changsha cable factory.Shortcomings such as the telpher of these patterns exists that overall dimension is big, Heavy Weight, carrying inconvenience and thrust deficiency; The clamping force of cable can not change the automatic compensation adjustment of realization with external load simultaneously, therefore meet the inhomogeneous or clamping force of cable size greatly in case during above lateral pressure that cable allowed, cable will sustain damage or destroy, and will seriously influence construction quality and progress.

The purpose of this utility model provide a kind of external form little, in light weight, be convenient to carry and the telpher of the high thrust that is damaged when avoiding cable to clamp overload.

Telpher of the present utility model comprises:

One underframe, one is fixed in the transmission mechanism on the described underframe, and described transmission mechanism comprises a micromachine, a reduction box and output shaft, and described reduction box comprises a pair of reduction gearing and a pair of worm and gear; One clamp system is installed on the fixed support of the two side ends that is fixed on underframe, and is arranged on the track conveying device on the described transmission mechanism; It is characterized in that: described clamp system comprises two guide posts, an adjustment screw mandrel and a planker, described two guide posts are horizontally through planker joins with the fairlead cunning that is arranged on its midfeather and the sidewall respectively, and the two ends of guide post are fixed by described fixed support respectively; Described adjustment screw mandrel is tied so that planker is done laterally moving with respect to underframe with the mutual spiral shell of nutplate on the intermediate inner wall that is fixed on planker; In the described track conveying device one be fixedly connected in planker, can move laterally with planker, described track conveying device, comprise the connecting gear of forming by roller chain and sprocket wheel, at the topped abrasive rubber piece between two ends up and down of described chain unit; One regulates the stage clip of buffering in advance when being used for cable and clamping of accurate Calculation, so that by its contraction planker is moved with the amount of contraction that equates when thrust surpasses predetermined value; Also comprise another group transmission mechanism, it comprises a micromachine, a reduction box and output shaft, and it and planker are connected, and can synchronously move laterally with planker and track conveying device.

Described underframe adopts steel tubes to make, and deceleration box adopts aluminium alloy to make.

The utility model has adopted two drive transmission devices that telpher thrust is greatly increased, and drives good stability simultaneously; Owing to guaranteeing under the situation of structural strength to adopt, weight reduction widely, be convenient to carrying and construction than light material and compact structure; The more significant advantage of the utility model is: since after the abrasive rubber piece being set on the track conveying device and the stage clip buffer unit is set in clamp system, can make cable carry crawler belt (support) thus produce float and decompression when making the power excess load of clamping cables to avoid damaging cable.

Now come the purpose of this utility model and technical characterictic thereof are made specific description by an embodiment and in conjunction with its accompanying drawing.
