Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
The present invention increases torque using ratchet mechanism, and then increases and twist the dynamics of nut of tearing open, makes operator at a distance still
Energy easy removal and installation electrical equipment, bearing 5 is provided with the two ends of ratchet shaft 13, can reduce the transmission torque of ratchet shaft 13
Resistance, the dynamics of corresponding increase pullover 1.Specific structure is referring to shown in Fig. 1, Fig. 2, and the upper end of the insulation body of rod 8 is connected
There is a ratchet mechanism, ratchet 15 is articulated with the inwall of pawl seat 14, ratchet shaft 13 of the detachable connection of pullover 1 in ratchet mechanism
Upper end, the lower end of ratchet shaft 13 is provided with spacing shoulder 6, and the two ends coordinated in ratchet shaft 13 and pawl seat 14 are respectively equipped with bearing 5,
Closure 3 is provided with the upper end of pawl seat 14, the lower end of pawl seat 14 is fixed with connector 11, and connector 11 is provided with blind hole
10, blind hole 10 is interior to be provided with spring 7, and the insulation body of rod 8 is fixedly connected with the lower end of connector 11.When the downward operation in the head of operation bar
When, the spacing shoulder 6 of ratchet shaft 13 can avoid ratchet shaft 13 from moving down, and spacing shoulder 6 is in blind hole 10, and blind hole 10 is used to accommodate
Spring 7, spring 7 is connected with the lower end of ratchet shaft 13；Spring 7 plays a part of the nut screw for compressing dismounting or turning, due to
In it is long-range when, dynamics on hand is difficult all to be delivered to stress point, and compression, spiral shell easy to disassemble are played a part of using spring 7
It is female.Spring 7 also plays a part of support limit to ratchet shaft 13.
Wherein, electric power overhaul is 1-5m with the length of insulation operation bar, and preferred length is 3-4m.
Buzzer siren 4 is provided with the outer wall of pawl seat 14.Buzzer siren 4 is set in end, sent out when object is powered
Go out alarm signal, operator is taken measures, it is to avoid dangerous generation.
During due to electric power maintenance operation, operator needs to adjust and select suitable operation position according to the position of maintenance thing
Put, while being typically also required to operation of ascending a height, in order that operating type more optimizes, typically selection can be simultaneously right as far as possible by operator
Several positions carry out the position of operation, so, and some maintenace points can be in high position, and some meetings are in lower position, i.e., far and near high
It is low all possible different, so, for needing nut screw to be mounted, nut screw is first put in pullover 1, for a high position
That puts is also more convenient, and for lower position, then nut can not be fixed in pullover 1, and maintenance point is then sent at a distance,
Therefore magnetic patch 2 is inlayed in the inside of pullover 1, so using magnetic, nut is held the maintenace point for being then fed into and specifying, so saved
Power is time saving, easy to operate, it is to avoid change many troubles such as position, meanwhile, the nut under dismounting can also be inhaled in pullover 1
On, it is to avoid the danger arbitrarily dropped.
Point is overhauled in order to which suitable far and near height is different and changes the cumbersome of position, and the insulation body of rod 8 selects hollow drawing and pulling type to stretch
Insulating bar.Expansion link of the prior art can be used, because multistage needs the expansion link of joint connection in site mode to carry inconvenient, and
And, the distance estimated sometimes is also less accurate, therefore, using the insulating bar of pull one, according to actual flexible apart from pull
Bar, using more flexible and convenient.
The expansion link that the present embodiment is enumerated is as follows：The top of the described insulation body of rod 8 is withdrawing part 18, and bottom is supporting part
19, the perforation 16 of some lateral direction penetratings is vertically evenly equipped with withdrawing part 18, the upper end of supporting part 19 is provided with straight with the perforation 16
The equal lateral connection hole in footpath, withdrawing part 18 is through in supporting part 19, and passes through the bolt through lateral connection hole and perforation 16
Pair 17 is fixedly linked.Some perforation 16, any one can be connected with the lateral connection hole of supporting part 19, so, increase and stretch
The random flexibility of contracting bar adjustment, also makes operator be easier to find the length of the insulating bar of suitable distance, it is to avoid operator
The crooked orientation for waiting and adjusting body is also needed to, meanwhile, the connection fastening of bolt pair 17 also makes the insulation body of rod 8 more integrated, makes entirety
On more stablize, transmission power preferably.
Anti-slip veins 9 are provided with the lower end outer wall of the insulation body of rod 8.Due to the general band gloves operation of operating personnel, easily skid,
Anti-slip veins 9 are set, also avoids operator from being held when operating and skids, reduce the efficiency of operation.
Further, connector 11 is fixedly connected with pawl seat 14 by the internal and external threads being engaged, connector 11 with absolutely
The edge body of rod 8, which is adopted, to be screwed.Using threaded connection fastening, make operation power transmission more stable, connection assembly and disassembly are easy, be not easy to damage
Bad, service life is long.
The present invention increases torque using ratchet mechanism, and then increases and twist the dynamics of nut of tearing open, makes operator at a distance still
Energy easy removal and installation electrical equipment, bearing is provided with the two ends of ratchet shaft 13, can reduce the transmission torque of ratchet shaft 13
Resistance, the dynamics of corresponding increase pullover 1, while setting buzzer siren 4 in end, alarm sends when object is powered
Signal, makes operator take measures, it is to avoid dangerous generation.
