The device has simple structure, and can automatically lock the ladder head, prevent a circuit lead from dropping from the ladder head, ensure the safety of operating personnel and avoid high-altitude drop accidents.
Description
One, technical field: the utility model relates to the charged ladder of an a kind of aerial power transmission line blocking device.
Two, background technology: electric power keeps in repair when carrying out equipotential live line work, and up and down during rope ladder, a ladder blocking device is in open mode to employed rope ladder ladder head all the time personnel.Personnel are when upper and lower rope ladder, and rope ladder rocks bigger, easily make the rope ladder head suspended end by coming off on the lead, cause the ladder head to come off personal height falling accident, the personal safety that seriously jeopardizes the staff.By analyze ladder head come off main cause have following some: 1, line conductor has elasticity, and personnel make lead rock up and down the time, and terraced head suspension end is easily by deviating from the lead; 2, terraced head suspension end belongs to circular configuration, and when circuit rocks 3/4 semicircle place, a ladder two ends discontinuity easily comes off from lead; 3, personnel step on the rope ladder top and can open locking, can not guarantee ascending stair personnel's personal safety.
Three, summary of the invention: the purpose of this utility model is that providing a kind of to people can ensure the charged ladder of an aerial power transmission line blocking device of operating personnel's safety automatically to a ladder locking.
The purpose of this utility model is achieved in that the charged ladder of an aerial power transmission line blocking device, integral installation is located on the rope ladder, it comprises the locking catch, and the torsion spring of control locking catch switch, slide bar, installing is one on a sidewall at the incoming line place of rope ladder ladder head, the opposing sidewalls place is provided with hasp, locking catch and active connection of axle, be with torsion spring on the axle between locking catch and ladder head, the locking catch is L shaped, and its horizontal edge end has the bayonet socket corresponding with hasp, there is backguy in vertical edge upper end system, after the transmission ring that is welded on the ladder side is passed in backguy, be connected, between two slide blocks, be connected with slide bar with the slide block that is placed in the ladder side.
The utility model is simple in structure, can be automatically carry out locking to the ladder head, prevents that line conductor from being deviate from by the ladder head, ensures operating personnel's safety, avoids the high-altitude falling accident.
Four, description of drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is the charged ladder of an aerial power transmission line blocking device structural representation.
Legend: 1, hasp, 2, terraced head, 3, lock bolt, 4, pulley, 5, the locking catch, 6, the lanyard transfer wheel, 7, ladder, 8, transmission ring, 9, slide block, 10, slide bar.
Five, the specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, the charged ladder of an aerial power transmission line blocking device integral installation is located on the rope ladder, and it comprises locking catch 5, and torsion spring, the slide bar 10 of control locking catch 5 switches.Installing is one on a sidewall at the incoming line place of rope ladder ladder 2, and this axle is a dead axle.Opposing sidewalls place at aforementioned ladder 2 sidewall is provided with a hasp.The corner of L shaped locking catch 5 is placed on the aforementioned axis, vertical edge outwardly, both active connections.Be with torsion spring on the axle of locking catch 5 and ladder 2, torsion spring one end is connected with locking catch 5, and other holds and links to each other with axle.The horizontal edge end of locking catch 5 has the recess corresponding with hasp 1, and there is backguy in vertical edge upper end system.After the transmission ring 8 that is welded on ladder 7 sides is passed in backguy, be connected, be connected with slide bar 10 9 of two slide blocks with the slide block 9 that is placed in ladder 7 sides.
For further guaranteeing combining of ladder 2 and lead, bore a screw on ladder 2 top, be rotary with lock bolt 3 in the hole, in the time of need stopping at the operation of a certain position, can lead and pulley 4 be compressed by lock bolt 3, make rope ladder to move, the safety of increase operation.Install lanyard transfer wheel 6 in ladder 7 both sides near ladder 2 place simultaneously, alleviate the trouble of the hand-held lanyard of operating personnel.
Under the effect of torsion spring, locking catch 5 is in blocking always, like this when the upper and lower rope ladder of operating personnel, can guarantee combining of ladder 2 and lead, avoids occurring the phenomenon of both disengagings.When needs are opened locking catch 5, with pin slide bar 10 is stepped on downwards, slide bar 10 drive slide blocks 9, the pulling backguy is outwards overturn thereby spur locking catch 5 tops, and locking catch 5 is opened, and terraced at this moment 2 can break away from lead.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
