Abstract
The utility model discloses a false climbing prevention device for a turnover safety maintenance platform of an electric power steel tube tower. The device comprises a false climbing prevention lock and a line signboard, wherein the false climbing prevention lock is arranged on a platform turning plate; the line signboard is fixed on a cross arm through bolts; the false climbing prevention lock comprises a lock hook and a buckle lock which are arranged on two sides separately; one end of a buckle lock pull rod is connected to the buckle lock, and the other end of the buckle lock pull rod is hooked to the lock hook; a key is inserted into the buckle lock. A high-voltage line of a multi-loop power transmission steel tube tower of an electric power facility consists of a plurality of lines and a steel tube tower; when the high-voltage line needs to be maintained, the false climbing prevention device has line marking and warning functions; when one of the lines needs to be maintained, the double-insurance effect of marking the number of the line on an assignment list and specifying a special key for false climbing prevention is achieved; during operation, normal operation of other lines is not influenced.
Description
Technical field
The utility model relates to the safety inspection stage apparatus field of power steel pipe tower, specifically the error-climbing device of the turning safety inspection platform of a kind of power steel pipe tower.
Background technology
In prior art, CN201020142791.9 discloses with tower multiloop power transmission steel tower mis-climbing prevention locking device, and its design weak point is that operation is too complicated, unreasonable structure, and the defect such as base support is firm not:
This circuit label bar is unreasonable with the reverses direction design of warning trip lever, because steel tower divides left and right circuit, its mis-climbing prevention locking device can only fall to a direction, in the time of dextrad circuit, be overturning left so, in the time of left-hand circuit, it is also overturning left, and cross bar and montant are split designs, complex operation.Considerably inconvenient in the time of work high above the ground like this.
Base support is firm not, its base support is by the moulding of corrosion resistant plate cutting and bending, adopts the method for welding to connect, and cuts material too thin, is easily out of shape and welds the shortcomings such as not in place in the time of welding.
In the time that steel tower installation mis-climbing prevention locking device is twisted bolt, needing two hands cut installs the defects such as complicated, securing member lock nut meeting transfer, brings inconvenient factor in the time of work high above the ground.
Because the design of lock is not opened and the positioner of lock core, lock pin by under the elastic force effect of spring in normally off, must with under key turns just open, be exactly blocking once hand one is put, in the time of release, need two hand operations, the handspring of unblanking of hand turns warning mark bar.In the time of work high above the ground, more make troubles.
Utility model content
In order to solve the above-mentioned technical problem existing in prior art, the utility model provides the error-climbing device of the turning safety inspection platform of a kind of power steel pipe tower, comprise the error-climbing lock that is arranged on platform turnover panel and be fixed on the circuit nameplate on cross-arm with bolt, described error-climbing lock comprises the latch hook and the padlock that set up both sides separately, padlock pull bar one end is connected in padlock, another end hook is in latch hook, and key inserts in padlock.
The error-climbing device of the turning safety inspection platform of power steel pipe tower of the present utility model is one of main accessory in the safety inspection stage apparatus of power steel pipe tower, electric power facility multiloop power transmission steel tube tower high-tension line, by many circuits and steel tube tower and form, in the time needing repairing maintenance, the utility model has played sign and the warning function of circuit, in the time that a circuit needs repairing maintenance, the double insurance of assigning single upper bright circuit number of emblem and appointment error-climbing private key, does not affect the normal operation of other circuit when operation.The utility model is a kind ofly in the time of production operation, hazards, adverse factor be controlled in safe range and prevention, reduce, eliminate the facility of the set safety sign of harm, device flag, safe police timberline, security protection, steps on more livewire work and cause unnecessary casualty accident in order to avoid wrong.
Brief description of the drawings
Fig. 1 is the STRUCTURE DECOMPOSITION figure of the error-climbing device of the turning safety inspection platform of power steel pipe tower of the present utility model;
Fig. 2 is the schematic diagram of the error-climbing lock of the error-climbing device of the turning safety inspection platform of this power steel pipe tower;
Fig. 3 is the schematic diagram of the line identification board of the error-climbing device of the turning safety inspection platform of this power steel pipe tower.
Detailed description of the invention
Below in conjunction with accompanying drawing the utility model is described in further detail explanation.
As Figure 1-3, the error-climbing device of the turning safety inspection platform of power steel pipe tower of the present utility model, comprise the error-climbing lock 2 that is arranged on platform turnover panel 1 and be fixed on the circuit nameplate 5 on cross-arm 4 with bolt 3, described error-climbing lock 2 comprises the latch hook 6 and the padlock 7 that set up both sides separately, padlock pull bar 8 one end are connected in padlock 7, another end hook is in latch hook 6, and key 9 inserts in padlock 7.
The procedure of processing of padlock 7, padlock pull bar 8, latch hook 6 is as follows: 1, blanking, 2, drawing and forming, 3, edge-cutting belt punching, 4, moulding bends, 5, the step such as bending.
The procedure of processing of circuit nameplate 5 is as follows: 1, blanking, edge-cutting belt punching, 2, printing, etc. step.
Shown in the above and figure is only preferred embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
