Abstract
A locking device to avoid mistakenly climbing power lines erected on the same tower is characterized in that a screw hole (5) is opened at the bottom of the concave base (1); a plywood (4) is positioned at the bottom of the concave base (1) through a screw hole (5) and a bolt (6); one end of an openable railing (2) is positioned in the concave base (1) and hinged on the concave base (1) through a cylindrical pin (7); a lock cylinder (3) is positioned at one side of the concave base (1) and a flexible tapered end (8) on the lock cylinder (3) is positioned in the lock hole (9) on the openable railing (2). The utility model only uses two types of keys in the entire circuit, namely, a key for a loop circuit. When a certain loop circuit needs to be shutdown for maintenance, the staff can only use the key to the switching lock to open and raise the railing to enter the working place, thus basically avoiding mistakenly climbing the electrical circuit and electrocution deaths. In addition, the utility model has simple structure, light weight, convenient installation and operation, and no rusty.
Description
Technical field
The utility model relates to the anti-error locking device of stepping on of a kind of wiring on the same tower power transmission sequence.
Background technology
Along with the high speed development of power grid construction, increase day by day with the tower erection power transmission sequence.The arable land of saving is arranged, reduce cost though power transmission sequence adopts with tower erection design and construction, plurality of advantages such as easy construction, operation has brought potential danger and hidden danger to maintainer's rod-rising tower simultaneously.Use on double-circuit line mostly with the tower erection power transmission sequence, and the line name Chinese character part is identical, mainly adopts the method that dual coding, colour code and I return, II returns to distinguish.On with the tower erection power transmission sequence during interruption maintenance, the major measure of taking is the requirement operating personnel conscientiously checks circuit before stepping on tower title, dual coding and a colour code, hangs warning sign in charged side, strengthens monitoring etc. in stepping on the tower process at present.But lack the behavior that necessary device comes the control operation personnel on the circuit, also do not accomplish perfectly safe and a hundred per cent.Having a power failure with tower erection power transmission sequence one time in recent years, another rewinds in the service work of electricity, and staff's mistake is stepped on alive circuit, causes the get an electric shock and die situation of accident of the person to happen occasionally.
Summary of the invention
The technical problem that the utility model solves: design the anti-error locking device of stepping on of a kind of wiring on the same tower power transmission sequence, two kinds of keys are only used on the road completely, promptly a loop line road is a kind of, when a certain loop line road needs interruption maintenance, step on the tower personnel and can only open locking with corresponding switching lock key, start railing and just can enter the service position, stopped staff mistake substantially and stepped on alive circuit, cause the get an electric shock and die situation of accident of the person to take place.And simple in structure, in light weight, fitting operation makes things convenient for, not corrosion.
Technical solution of the present utility model: the anti-error locking device of stepping on of a kind of wiring on the same tower power transmission sequence, by spill base (1), open type railing (2), lock core (3) and clamping plate (4) constitute, the bottom of spill base (1) is shaped on screw (5), clamping plate (4) are by screw (5), bolt (6) is installed in the bottom of spill base (1), one end of open type railing (2) is positioned at spill base (1) and is hinged on the spill base (1) by straight pin (7), lock core (3) is installed in a side of spill base (1), and the elasticity tapered end (8) on the lock core (3) is arranged in the lockhole (9) on the open type railing (2).
The right-hand member inboard of clamping plate (4) is fixed with Improved mat (10), and the other end of open type railing (2) is fixed with warning sign board (11).
Lock core (3) is triangle lock core or quadrangle lock core.Warning sign board (11) top is printed with " forbidding to cross " caution poster, and the bottom is printed with electric pressure and line name.
Advantage that the utility model compared with prior art has and effect:
1, in light weight: this device adopts aluminum alloy materials making total weight to have only 1.5 kilograms.
2, easy for installation: as when installing on the line, to be fixed on the cross-arm by two bolts and clamping plate and to get final product.
3, simple to operate: two kinds of keys are only used on the road completely, and promptly a loop line road is a kind of, steps on the tower personnel and opens locking with corresponding switching lock key, starts railing and can enter the service position.
4, not corrosion: this device selected materials is aluminium alloy, copper material all, is difficult for corrosion.
5, effect is remarkable: this device can stop effectively to be stepped on tower operating personnel mistake and steps on alive circuit, because a kind of key can only be opened a kind of locking, locking is not opened, railing is not steeved, personnel just can't pass through, thereby can avoid mistake off one's guard owing to the operating personnel and that monitoring reason such as not in place causes to step on.

Embodiment
1,2,3,4,5,6 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
The anti-error locking device of stepping on of a kind of wiring on the same tower power transmission sequence, constitute by spill base (1), open type railing (2), lock core (3) and clamping plate (4), spill base (1) adopts aluminium alloy casting to form, and the bottom is shaped on screw (5), clamping plate (4) are installed in the bottom of spill base (1) by screw (5), bolt (6), and the right-hand member inboard of clamping plate (4) is fixed with Improved mat (10).Open type railing (2) is an aluminium alloy pipe, and the one end is positioned at spill base (1) and is hinged on the spill base (1) by straight pin (7), and the other end is fixed with aluminium and pulls the warning sign board of making (11).Lock core (3) adopts copper material to make, and be installed in a side of spill base (1), and the elasticity tapered end (8) on the lock core (3) is arranged in the lockhole (9) on the open type railing (2).Lock core (3) is triangle lock core or quadrangle lock core, is furnished with two kinds of keys of interior triangle or interior quadrangle, is used for opening and closing lock.Warning sign board (11) top is printed with " forbidding to cross " caution poster, and the bottom is printed with electric pressure and line name.
Installation method: the wiring on the same tower power transmission sequence is anti-error to be stepped on all cross-arms of every basic iron tower that locking device must be installed in the wiring on the same tower circuit and just can play effect, installation method is this device card to be contained on the cross-arm (12) of wiring on the same tower circuit with two bolts (6) by clamping plate (4), one side is adorned three interior triangular form lock core locking devices, and opposite side is adorned three interior quadrangle lock core locking devices.Clamping plate (4) can be exchanged according to end about the position of cross-arm (12).For preventing that stepping on the tower personnel passes through railing, setting height(from bottom) is the waist location (about 0.9 meter～1.0 meters) of human body.
Using method: before a certain time in interruption maintenance wiring on the same tower circuit, the work director issues and steps on the tower operating personnel and open and close lock key accordingly, as: the operation of interior triangular form lock core locking device side just issue open in the key of triangular form lock core locking.When stepping on the tower operation, when the operating personnel arrives the cross-arm position, have only use the key corresponding (13) to open lock core (3) to lift railing (2) with locking after, can enter cross-arm, prevent that operating personnel's mistake on the tower from stepping on the purpose of charged side thereby reach.
