Abstract
The utility model relates to an interlocking device of an inserting-and-connecting box and belongs to the safety technical field of power transmission and distribution. The interlocking device comprises a switch operating component interlocked with a switch of the inserting-and-connecting box, a limiting pole fixed at the lower side of a rotating shaft of the switch operating component, and an ejection pole which can lift a locking limiting pole and is arranged on a stander below the limiting pole; the lower end of the ejection pole is joined together with a driven crank which is fixedly connected with a drive crank by a crank shaft, the drive crank is joined together with a locking pin, one end of which is articulated and supported. In the process that the inserting-and-connecting box is inserted and connected in a bus, the interlocking device drives the ejection pole to be lifted and to lock the limiting pole, thus leading the switch operating component to be not capable of moving and ensuring that the switch of the inserting-and-connecting box can not be witched in when the inserting-and-connecting box is not completely inserted and connected in the bus; when the inserting-and-connecting box is completely inserted and connected in the bus, the switch is in a switching-in position, and operation staffs can not loose the locking pin and pull out the inserting-and-connecting box, thus ensuring the operation staffs to be safe; the manufacturing, assembling and maintenance are simple, and the cost is economic.
Description
Technical field
The utility model relates to a kind of jack box interlock, and especially a kind of mechanical interlocking device that is mainly used between various bus jack box chamber doors, pin, the lock pin etc. belongs to power transmission and distribution safe practice field.
Background technology
Along with the pay attention to day by day that the power transmission and distribution field requires big capacity, flexible tap, reusable, easy installation and maintenance, the use of bus product is more and more general.From the angle of using, the user bus on-the-spot install finish after, what frequently contact and operate should be jack box, therefore for guaranteeing jack box and operating personnel's thereof safety, answers reliable design, complete jack box interlock.
Understand according to the applicant, the bus jack box major part of Xiao Shouing does not have interlock or does not have complete interlock in the market, such as chamber door being arranged and to lock pin chain, but does not have chain between chamber door and pin, pin and lock pin; Though it is chain that some product has, or mechanism is too complicated, and manufacture difficulty is big, cost is high; Mechanism is unreliable, can not guarantee that the mutual action of each work package of interlocking gear cooperates.
The utility model content
The purpose of this utility model is: the weak point that exists at prior art, for the bus jack box provide a kind of can reliably chain jack box interlock, thereby assurance bus jack box and operator safety.
In order to reach above purpose, jack box interlock of the present utility model comprises the switching manipulation assembly with the jack box switch gearing, the rotating shaft downside of described switching manipulation assembly is fixed with gag lever post, the push rod of liftable locking gag lever post is housed on the following methods, rack of described gag lever post, the lower end of described push rod is connected with driven crank, described driven crank is connected by crank axle and driving crank, and the hinged lock pin of described driving crank and an end is connected.
Be plugged in the bus process at jack box, the stressed rotation of lock pin, order about the driving crank rotation, drive the driven shaft rotation, and then drive push rod rise locking gag lever post by crank axle, the switching manipulation assembly can't be moved, thereby when guaranteeing that jack box does not insert bus fully, the jack box switch can't close a floodgate, simultaneously when jack box inserts bus and switch fully and is in closing position, operating personnel can't unclamp the lock pin and transfer to jack box, to guarantee bus jack box and operator safety.After jack box is in place, the lock pin preset.By with above-mentioned opposite process push rod being fallen, thereby make gag lever post break away from locking, the jack box switch can carry out branch, closing operation freely, and its manufacturing, assembling, maintenance are simple, cost economy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Embodiment one
The jack box interlock of present embodiment mainly is made up of lock pin 1, driving crank 2, crank axle 3, driven crank 4, push rod 5, spacer pin 6, back-moving spring 7, frame 8, gag lever post 9, switching manipulation assembly 10 and location-plate 11.Their mutual alignment and assembly relation are: the lower end of lock pin 1 is shaped on the gib head that lower surface tilts, and the upper end is hinged, and the middle part is connected by moving sets with the prong of driving crank 2.Driving crank 2 is mutually permanently connected by crank axle 3 and the driven crank 4 that is positioned at the other end.The prong of driven crank 4 is connected by moving sets with the lower end of push rod 5.The middle part of push rod 5 is fitted with spacer pin 6, and the top passes the plane of frame 8.Push rod section between spacer pin 6 and frame 8 planes is set with back-moving spring 7.Be equipped with the top of push rod 5 can be by the gag lever post 9 of locking, and the turning handle in the switching manipulation assembly 10 of this gag lever post 9 and control switch action is connected.
In addition, limiting plate 11 is welded on the grafting chamber door, is positioned at a side of switching manipulation assembly 10, when switching manipulation assembly 10 is in the inductive switch closing position, is blocked by switching manipulation assembly 10, opens thereby can limit chamber door when switch is in closing position.
The course of work of the jack box interlock of present embodiment is as follows: jack box is in being plugged into the bus process, and the lower surface of lock pin 1 is stressed to laterally rotate it, is with driving crank 2 and drives driven crank 4 corresponding rotations by toggle-action lever 3.Driven crank 4 causes push rod 5 upwards to slide by moving sets, and when lock pin 1 did not put in place, the active force that push rod 5 overcomes back-moving spring 7 was in upper, thereby locking gag lever post 9 can not rotate switching manipulation assembly 10, and switch also just can not close a floodgate.When jack box peg graft put in place after, lock pin 1 backward rotation under the effect of back-moving spring 7, push rod 5 is in the next, limited pin 6 is spacing, breaks away from the locking to gag lever post 9, can carry out branch, closing operation this moment smoothly.
This shows that the device of present embodiment has guaranteed that jack box does not insert bus fully and locks pin when putting in place, jack box can't close a floodgate; And jack box peg graft in place after, switch can freely divide, close a floodgate.In addition, when switch was in closing position, the location-plate on the chamber door was by the switching manipulation component limitations, and chamber door can't be opened.When jack box inserted bus and switch fully and is in closing position, operating personnel can't unclamp the lock pin and transfer to jack box.Therefore, the jack box interlock of present embodiment can be realized the mechanical chain between various bus jack box chamber doors, pin, the lock pin etc., to guarantee bus jack box and operator safety.
