Abstract
A flexible cable laying tensioner for flexible cable erection work such as power transmission line and high-altitude cableway erection. The friction tensioning wheel train is characterized by comprising a large tensioning wheel and a group of small tensioning wheel sets. Has the advantages of simple structure, small volume, light weight and convenient transportation.
Description
The present invention relates in a kind of construction operation that is used for, particularly erecting flexible cable operation, when gentle Suo Zaizhan is put not with ground and various facility, trees, massif contact friction, injury-free to guarantee its surface, must use tensioner.
The single-wheel watt chain type that Japan yASUDA SEISAKUSHO.LTD. produces twines the rope tensioner (patent No.: be to be made of a big friction wheel and a watt of chain that is spirally wound on it JP755004).Its shortcoming is complex structure thereby makes relatively difficulty.Its structure can be referring to accompanying drawing 3.
The wheeled tensioner of parallel double that Canada TIMBERLAND company produces is made up of two friction regulating wheels that are arranged in parallel.All have cannelure on each is taken turns, the cannelure of two correspondences is in half slot pitch of axial dipole field.When gentle rope be wound into apply braking force on two regulating wheels and to regulating wheel after, the operation of strap showing and placing of the tension just can soften.The major defect of this machine is bulky, preponderance, gives transportation, particularly mountain construction brings great difficulty.Its structure can be referring to accompanying drawing 4.
The objective of the invention is for construction operation, particularly erecting flexible cable operation provide a kind of simple in structure, volume is little, the novel tensioner of transportation in light weight, convenient.
This purpose reaches by following public technical scheme:
The similar of this tensioner and the wheeled tensioner of parallel double promptly mainly is made up of friction tensioning train, wheel shaft, band brake, tenslator and frame etc.The improvement of being done is: two paralleling double wheels in the tensioning train that will rub are originally changed into by a big regulating wheel and Xiao Zhang's bearing up pulley group and are constituted.Little wheels are made up of several Xiao Zhang's bearings up pulley.Each little regulating wheel can rotate independently, its axis all with the parallel axes of big regulating wheel, and its core wheel line is a circular arc line, core wheel one segment distance of big regulating wheel is departed from the center of circle of this circular arc line.The enveloping outer enclosure that big regulating wheel and each Xiao Zhang's bearing up pulley are formed is approximately one section ellipse.On the external cylindrical surface of big regulating wheel and each little regulating wheel, all have several width and the identical cannelure of spacing.Cannelure on any one little regulating wheel all with adjacent little regulating wheel on cannelure axially differing the distance that equates successively.Also differ the distance that this equates between two steamboat cannelures on the limit and two the adjacent annular grooves of corresponding bull wheel.Make the envelope of each steamboat institute open loop shape bottom land form a section spiral line in the space like this.And the corresponding annular bottom land smoothly joins on the two ends of this helix and the big regulating wheel.So, after gentle rope is wound into friction tensioning train and to big regulating wheel, imposing braking force, then gentle rope can be put by belt tension traction exhibition.
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the friction regulating wheel architecture schematic diagram of tensioner of the present invention.
Fig. 2 is that 1 A is to view.
Fig. 3 is the structural representation of single-wheel watt chain type tensioner.
Fig. 4 is the structural representation of the wheeled tensioner of parallel double.
Referring to Fig. 1 and Fig. 2.The wheel shaft of big regulating wheel 2 and Xiao Zhang's bearing up pulley group 3 all is assemblied on the frame 4, and can independent rotation.Xiao Zhang's bearing up pulley group 3 is made up of 9 Xiao Zhang's bearings up pulley, and the line of its core wheel is one section circular arc line, and the center of circle C of circular arc line is positioned at next segment distance of core wheel O of big regulating wheel 2.The core wheel O ' of the 5th little regulating wheel is a symmetrical centre with O ' on the extended line of OC, uniform 4 the little regulating wheels of each five equilibrium of both sides, and the external diameter of each successively decreases successively.Cannelure on cannelure on any one little regulating wheel and the adjacent little regulating wheel is axially differing the distance that equates successively.On the cylindrical of big regulating wheel 2, also have the cannelure of several and Xiao Zhang's bearing up pulley cannelure same widths and spacing.The wire rope handling method of gentle rope 1 is wrapped in earlier in the cannelure of big regulating wheel 2 as shown in Figure 2, more successively in the cannelure of each little regulating wheel, opens up on the big regulating wheel more at last and puts.
That the present invention has is simple in structure, volume is small and exquisite, weight is light, the advantage of convenient transportation, and the data from following contrast table can be confirmed.
The wheeled the present invention of Canada's parallel double is suitable for flexible cable
