Description
Technical field
The utility model relates to that the big discrepancy in elevation span of a kind of transmission line of electricity is portable to go out the Line tool, the portable outlet rope ladder head of the big discrepancy in elevation span of particularly a kind of transmission line of electricity.
Background technology
Lead wire and earth wire, insulator, damper etc. are the important composition parts of high pressure overhead power line, and long term exposure is in abominable natural environment, and the defective probability of happening is higher.Lead is unique parts of transmission of electric energy, is in operation to meet disconnected strand or damage, will directly have influence on the transmission line of electricity safe and stable operation, and serious meeting causes heating to cause the broken string accident; Insulator is the critical element of line insulation, in case low, null value occurs, the electrical insulation intensity with reducing circuit causes circuit lost territory fault; Damper is the critical piece that absorbs lead aeolian vibration energy, is in operation sliding race or damage take place, and causes tired disconnected strand of lead, gold utensil to wear and tear and the accident that breaks, goes offline most probably.Therefore the staff need adopt the rope ladder head outlet to carry out high-altitudes such as lead is studied for a second time courses one has flunked, insulator is changed, damper the resets scarce operation that disappears.Existing rope ladder head mainly is made up of pulley that can slide along lead and the rope ladder head support body that hangs on two pulley brackets.The rope ladder head of this structure, for being main with high mountain and hills a lot, the area that the physical features drop is bigger is difficult to be suitable for.Overhead transmission line is usually crossed over high and steep mountains, rivers and lakes, has a large amount of big discrepancy in elevation shelves, and this just studies for a second time courses one has flunked work such as lead, damper reset, insulator replacing and causes great difficulty to outlet.When using traditional rope ladder head outlet; Must closely cooperate each other by personnel on the tower and outlet operating personnel; Rope ladder head is positioned with the convenient working personnel operate accordingly through the control rope; This operating type, inefficiency, labour intensity are big and safety factor is not high, can't operate for the circuit of big discrepancy in elevation span at all.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and a kind of safety factor that improves the outlet operation is provided, and alleviates operating personnel's labour intensity, the portable outlet rope ladder head of the big discrepancy in elevation span of the transmission line of electricity of increasing work efficiency.
The portable outlet rope ladder head of the big discrepancy in elevation span of a kind of transmission line of electricity; Comprise rope ladder head support body, pulley; Be arranged at the pulley bracket of rope ladder head support body upper end; Pulley bracket is provided with the opening that pulley is snapped in lead, and its structural feature is: the portable outlet rope ladder head of the big discrepancy in elevation span of described transmission line of electricity is provided with check mechanism, and described check mechanism is connected with pulley.
On the portable outlet rope ladder head of the big discrepancy in elevation span of transmission line of electricity, set up check mechanism, in use, just can at any time this outlet rope ladder head be positioned needed position to carry out corresponding operation as required.
Described check mechanism includes taper sheath; End at pulley is provided with the bellmouth that matches with taper sheath; This bellmouth is coaxial with the axis hole of pulley, and described taper sheath is rotating to be set on the pulley spindle, and taper sheath matches with bellmouth on the pulley axis hole.
The check mechanism of this structure, when work, when the outlet rope ladder head put in place, the rotation conic cover can be realized the location to rope ladder head.Simultaneously, the fitness through between control taper sheath and the pulley can change the frictional force between pulley and the taper sheath, thereby changes the velocity of rotation of pulley on lead, plays the effect of regulating this outlet rope ladder head speed of service.Thereby make this outlet rope ladder head applicable on the lead with gradient.
Between taper sheath and pulley spindle, being provided with sleeve, is tight fit between described sleeve and the pulley spindle, adopts threaded engagement between sleeve and the taper sheath.
Between taper sheath and pulley spindle, add sleeve, can play the effect of protection pulley spindle like this.
Periphery at sleeve is intervally distributed with a plurality of along the axially extended elongated slot of sleeve; Taper sheath is provided with a hole along the extension of taper sheath one radius direction; Be disposed with holding screw, spring and orbicule at this place, hole, orbicule is positioned near sleeve and can moves at the elongated slot of sleeve.
Be provided with the blocking device of the closure of openings that is used to snap in lead on being used for pulley bracket at the opening part that is used to snap in lead on the pulley bracket.
The opening part that on pulley bracket, is used to snap in lead is provided with blocking device, after this outlet rope ladder head is snapped in lead, with blocking device locking, so just can prevent that the outlet rope ladder head from dropping from lead.
Described blocking device is for to be made up of an arc revolving fragment; One end of revolving fragment is articulated on the heel post of pulley bracket; The opposite side column of pulley bracket is provided with a Magnetic bolt, and the other end of revolving fragment is provided with the through hole that matches with Magnetic bolt.
The blocking device of this structure by the arc revolving fragment and be equipped with Magnetic bolt and constitute, can not damage the line body with wire external layer aluminium thigh touching moment in use, has guaranteed the safe and stable operation of lead body.Hang into moment at rope ladder head, by the slight recoil strength of contact wire, the back automatic immediate left-hand thread locking that rotates a circle makes rope ladder that the back is installed and shakes up and down like lead and can't throw off lead when serious, has guaranteed operating personnel's personal safety.
Between pulley and pulley spindle, be provided with rolling bearing,, improve the flexibility of its rotation to alleviate the frictional force of pulley rotating.
In sum, the utility model is compared the following advantage of prior art:
The portable outlet rope ladder head of the big discrepancy in elevation span of the transmission line of electricity of the utility model, the one, braking at any time in the operation process; The 2nd, can realize automatic blocking after installing; The 3rd, adopt the rolling bearing design to alleviate frictional force.Adopt the portable outlet rope ladder head of the big discrepancy in elevation span of transmission line of electricity of the utility model, have
(1) the big discrepancy in elevation of the transmission line of electricity application that goes out the Line tool can be avoided rope ladder head to break away from lead because of spring, deflection, thereby cause personal high falling accident, reduces the risk of personal injury, ensures job safety.
(2) the big discrepancy in elevation of the transmission line of electricity application that goes out the Line tool; (3 people's operations reduce to 2 people on original bar to have alleviated operating personnel's labour intensity on the tower; Wherein 1 people mainly is a control), shortened the activity duration (rope ladder head time shortening 3min is installed), improve operating efficiency.
