Can see from Fig. 2-1, Fig. 2-2: power transmission line passes from the belly of travel wheel, and travel wheel is a track with it then, the middle tube rolling (referring to Fig. 3-1, Fig. 3-2) in the above of rolling.The driven by motor of advancing (two sections) driving gear, promoting the outer again is the travel wheel work of tooth.
Be that gravity balance reduces deflection pressure, tooth is washed in the processing of travel wheel outer, will advance motor and driving gear are placed in during below, device center closely cooperates with it, just can at the uniform velocity reposefully travel wheel be driven.Otherwise, stress as if principal and subordinate's gear side being put, will increasing, influence balance.
Ask for an interview Fig. 3-1 and Fig. 3-2 simultaneously, pass because power transmission line is a cylinder from motor and travel wheel, bigger 10 centimetres so the block plate diameter of travel wheel 2 is designed to 30 centimetres than diameter of cylinder, leave the locus; Master gear is divided into two sections among the figure in addition, be " H " font, so both corresponding with travel wheel deep bid tooth, vacate central space again, space addition has up and down been abdicated about 10 centimetres position for power transmission line, and the double pendulum hammer impacts down main icing in advancing, so all power transmission lines can both pass through, ensure carrying out smoothly of de-icing work.
Continuous cylinder on the plate washer of travel wheel left side preferably adopts founding technology to be made into integral body, but when condition does not possess, then needs fastening tube is holed in the centre with the alloy axle, interts with screw and fixes, and the side produces same purpose.
Because the horizontal axis tam diameter is taken as 3cm, the sleeve that closely interlocks only increases the thickness part, so diameter is little, will advance too slow if do cylinder.So we again on the plate washer of travel wheel right side weld diameter be the cylinder of 20cm, can become the raising speed more than 6 times.
When horizontal axis tam after the left side plate washer fixes, again the left and right side plate washer is merged, closely connect with long bolt, form complete travel wheel.
Travel wheel speed and platform number calculate: excessive for avoiding quality, so we make the driving wheel diameter and the number of teeth travel wheel canine tooth half, be 12cm and 12 teeth, and to select direct current thus again be the servomotor that 24V, per minute 120 changes, took two turns in promptly 1 second, diameter is that the rolling tube of 20cm turns around with 24 tooth deep bid per seconds thereupon, thereby is calculated as follows:
Girth=20 * 3.14 ÷ 100=0.628m
Then a hour driving range is:
0.628×60×60÷1000＝2.26km
In every covering device darg 6 hours, if 50 kilometers icing circuits need:
100 ÷ (4 of 6 * 2.26) ≒
Because device is charged deicing, so can not overlap and keep a safe distance,, but implement de-icing work simultaneously so three power transmission lines of A.B.C are to adopt phase-splitting, required like this:
4 * 3=12 platform
Promptly 12 table apparatus of making of the design are constructed simultaneously, and 50 kilometers icing circuit just can all be abolished in 5,6 hours.With the method, also can expand to longer more multi-line.
Therefore this travel wheel promptly is a baffle plate, is again gear, has not only solved the fastening problem of horizontal axis tam but also improved the rolling gait of march, at one stroke several designs.
The deicing unit:
Swing motor in Fig. 2-1, Fig. 2-2, double pendulum hammer constitute the deicing unit.Fig. 4 amplifies signal, when motor obtains work order, promptly does 180
0Come and go to rotate, the upset in the slotted eye (being bar hole) that base plate is offered along lead thereupon of upper and lower arm resembles mechanical hand drive peening hammer and impacts icing on the power transmission line from the above and below, and these ice sheets will be shot down one by one, reach the deicing purpose.
Double pendulum hammer and common hammer are different, and we design and produce it and are arc shape, will form circular arc encirclement shape up and down for being commonly circular cable like this, and it is bigger to make it contact-making surface, and better effects if opens ice.
Brake unit:
Because of power transmission line is crossed over mountain after mountain, condensing of deadweight and ice sheet arranged in addition, will make the cable tenesmus, the also formation great slope that has often needs observation, adjustment etc. so hit in the ice.For preventing that stagnating fashionable dress deposits cunning, has designed brake units.Fig. 5 is the expansion schematic diagram of this unit, the braking mechanism structure is: stage clip 15c one end is connected with fixed head 15b, fixed head through screw on base plate 12, be fixed with a brake block 15 on the stage clip 15c other end, the active force of stage clip does not make brake block 15 separate with the cylinder 2c of travel wheel when being subjected to external force, and the action component of straight-wavy valve formula electromagnet 15a connects firmly through steel wire rope and brake block; Be equipped with on the described bearing pedestal 5 with two metal fork arm 5a that do 1 position-limiting action of power transmission line.
Press down bolt among the figure spring (stage clip) and brake block are fixed on the device base plate, spring is strutted brake block by self-acting power at ordinary times, when electromagnet obtains remote control command, it is charged adhesive, its wire is left behind brake block, and travel wheel is stopped operating, and reaches the purpose of Brake stop.
Dynamic poise device:
The charged deicer of single-phase work, should consider fixing assemblings on a metal base plate such as motor, travel wheel, electromagnet, accumulator jar, the reception of distant news and controller, also will solve the not oblique significant problem of balance, for this reason, we have taked multinomial measure, after being illustrated in respectively.
With the travel wheel cylinder is the strong point, and two side gear baffle plates are promptly avoided derailing, play position-limiting action again in inclination; Horizontal axis tam should roll with travel wheel and change, and provokes the device base plate again, has adopted drive bearing.
Circle closely cooperates with horizontal axis tam 4 in the bearing, can rotate with travel wheel; The both sides of bearing pedestal also are welded with two metal fork arm 5a, this prong is crossed but contact power transmission line not, this is not increase resistance when normally advancing, but when arbitrarily angled inclination occurring, four metallic tines just have one or two to prop up power transmission line as triangle hypotenuse opposite direction, make it that gradient is unlikely to be increased again.This is the another measure of strengthening balance.
On the device rigging position, we take into full account weight balancing especially.In the buck plate as Fig. 2-2, the motor of advancing, driving gear and double pendulum motor, double pendulum hammer all are arranged in the left and right sides under the travel wheel, have both guaranteed the work effect, again balanced weight.
Distant news reception and processing controller and accumulator jar are positioned over faces the place ahead, because the storage battery of about 4kg overweights the former greatly, so, as far as possible by middle installation.
Fig. 2-2 right side is the rearview that base plate loads, and the heavy balance iron of a 4kg is wherein arranged in the dynamic poise device, lays with the accumulator jar symmetry.Whole like this base plate is not oblique partially, held stationary.
More than to the reasonable arrangement of device position, be to utilize its quality to accomplish static balancing.
Along with the carrying out of de-icing work, device will inevitably be subjected to vibration and jolt, and also can produce inclination when serious, must adjust immediately this situation.But because of device is fixed, static balancing is at one's wit's end, so we are provided with the homestat as Fig. 7.
Level meter among Fig. 7 (being water container) is made balance detection, wherein is connected with two contacts (binding post) of negative power supply.Just often water level balance breaks away from two contacts; When device during toward any lopsidedness, liquid flow runs up to this side, and liquid level raises, promptly connect with this side lead, with negative supply give connect controller, controller starts upset, connects the backward rotation power supply of balance motor, motor rotation, master gear drives moving to the anti-direction of water monoclinic phase from gear of balance iron, up to balance again, and liquid level and lead disconnection, the motor dead electricity, mobile stopping.
More than by monitoring, conversion and control, the mode that balance iron oppositely moves, realization be dynamic equilibrium.This is an another unique design in this device.
The safety assurance of charged deicing: for preventing power transmission line tenesmus, wind swing etc., design its phase spacing to such an extent that substantially exceed state's scale value.As the alternate arcing distance of 220kV in two meters, but the phase spacing of power transmission line then common design is 7 meters, as seen leeway is big, icing is assembled in addition, increased weight and solidified, the swinging arc of line only can reduce, so, our single-phase deicer is limited in lateral dimension in 50 centimetres, is that safety guarantee is arranged fully.This also is that three power transmission lines of A.B.C adopt phase-splitting, but can implement the reason of de-icing work simultaneously.
In addition, form aerial conductor, cause alternate discharge, even short circuit, so we have made the bell-jar case lid Design Treatment that seals on the under shed, as Fig. 8 for to prevent that the ice cube that smashes from splashing.
Among Fig. 8, case lid 18 is fixed on (because of highlighting case lid here, so suspender belt and other device are not drawn again) on the base plate by four identical bolts; Case lid has the arc top, and is not only attractive in appearance but also give horizontal axis tam and travel wheel leaving space; The case lid longitudinal middle part has opening 18b, stays passage to power transmission line; The case lid bottom is middle complete empty wall structure.Case lid is through bolt 18a and bottom plate connecting.
The case lid length is of a size of: 60 * 50 * 92cm; The power transmission line opening size is: 12 * 60cm; Wide 12cm considers line footpath and icing influence, and high 60 is that the distance of looking into is worn to lead between cylinder in the case lid base, all leaves big leeway.
The bucket position, 40cm space of the following lengthening of base plate, the one, consider to 35cm combat arm length below the covering of swing; The 2nd, the ice cube that smashes up and down can be subjected to barrel wall restriction and vertical decline, it is disorderly to be unlikely to the four sides, and assurance thus tightens security.
Leave 5～10 cm bar shaped spaces between case lid and base plate, and laid the circumference hole that 3～10 cm differ in size (being trash ice via hole 1b) in advance on base plate, these are for being opened up leakage way, unlikely accumulation by the trash ice under hitting in the case lid that is closed.Swing arm and iron hammer are also pushing, are hitting, are draining the ice cube in the case lid when impacting ice covering on transmission lines in the practicality, so, can not store too many ice cube in the case lid, can not influence the carrying out of work.
This part is to the electromechanical structure of charged deicer, and comparatively careful Design Treatment has been done in operation principle, especially balance running and security protection etc., so the entity of producing like this has good operating state.
Circuit Design: each device of charged deicer install be provided with finish after, operation on the cable of high-altitude, also have problems such as power supply, distant news, control to need to solve, will make introductions all round below.
Working power:
Each motor, electromagnet etc. will be worked in the device, must need electric energy.Electric energy can be supplied with by ground civil power and vapour, diesel power generation, but such problem is to be with long lead plait, influenced by the mountain ridge, gully, may occur the obstacle that can not cross over sometimes.For this reason, our emphasis still is designed to the accumulator jar method.
As shown in Figure 10, compose in parallel again after connecting in twos by 4 12V accumulator jars, like this, series connection: can meet 24V direct current machine need of work, parallel connection: then lay in more multipotency.Thus, for advance, impact, the about 100 watts electrical appliance of gross power such as dynamic balancing, electromagnet, one group of storage battery can move about 20 kilometers, can satisfy the mileage of unit deicing in a day basically.
Remote controller:
A this charged deicer wherein significant role is to replace electrician's work high above the ground, so possess the remote operation controlled function.And the consideration topography and geomorphology, even the river that crossed over a hill, the signal transmission needs more than hundreds of rice, and therefore, we have selected the LM1000 high power transmission device shown in Fig. 9-1, can guarantee that signal sends to more than 1000 meters.
Receiver is then selected the device highly sensitive, that induction force is strong for use.Because this device main task is deicing, so remote control reception, reflector are under self Preliminary design, to the special order products of producer of fine quality.
Can see that from a receiver is made up of antenna, frequency division, control, relay and supply pin and connecting terminal block.Relay tip is shown in J1, and control pin inside joins, and often opens, public, normally closed contact sent by the 1.2.3 terminal respectively.Other same model relay J 2, J3, J4 connected mode are similar.
