Electrical verification handcart among the present invention is power with the electric power device, can reach maximum thrust, originally needing just can realize the several people to push away, shake as possible the power effect that just can reach as possible by control electric power device 1, in the course of the work, electric power device 1 provides power for thrust unit 3, finish the action of opening the door by the distribution on the thrust unit 3, thereby open high-voltage switch gear electrical verification door cashier's office in a shop.
Below describe the detailed structure of each important component part in the electrical verification handcart among the present invention in detail.
Fig. 4 is the concrete structure synoptic diagram of the fixed mount in the electrical verification handcart among the present invention, and as shown in Figure 4, the rear portion of this fixed mount 2 is the fixing fixed station 21 of electric power device 1, and the middle part is two stable pipes 22, and the front portion is an angle steel type sheet metal 23.All be provided with two slotted holes in the both sides of angle steel type sheet metal, be designated as 231 and 232 respectively.Wherein the height of slotted hole 231 is higher than slotted hole 232.Fig. 5 is the synoptic diagram of fixed station 21 parts among Fig. 4.
In order to make the electrical verification handcart in opening electrical verification door process, can not move backward owing to reacting force, preferably, fixedly connected at least one location sheet metal 4 in the rear end of fixed station 21, the free end of location sheet metal 4 can offset with ground fixture (for example cabinet angle steel of high-tension switch cabinet), draws back to prevent the electrical verification handcart.
Fig. 6 is the thrust unit among Fig. 1 and the part-structure synoptic diagram of electric power device, as shown in Figure 6, this thrust unit 3 have be Vee formation shape three link rods (in Fig. 6, link rod as two hypotenuses of Vee formation shape is labeled as 31, link rod as the base is labeled as 32), these three link rods form stable triangle rock-steady structure, and two link rods 31 at rear portion receive the thrust of electric power device 1, and anterior link rod 32 can play the effect that the structure of thrust unit 3 is fixed.
A fixed head 35 that be arranged in parallel along fore-and-aft direction is fixed at two ends, the base angle of three link rods (being the angle between link rod 31 and the link rod 32) respectively in the above.The outside of fixed head 35 be provided with fixed head 35 vertical direction extend on promote 33 and promote 34 down.Thrust unit 3 among the present invention adopts two modes of promoting, distribution 34 is used for promoting the linkage of opening the door of electrical verification door wherein, last 33 self-locking devices that are used to push open the linkage of opening the door of electrical verification door of promoting are gone up simultaneously and are promoted 33 and withstand top board, tilt upward to prevent whole electrical verification handcart.
In addition, on above-mentioned electrical verification handcart, can also increase other servicing units, for example, below the fixed station 21 of fixing electric power device 1 and angle steel type sheet metal 23 below be provided with wheel, can further facilitate the position that the user moves whole electrical verification handcart like this, so that it easierly enters the working position or withdraw from the working position.
In order to alleviate the weight of whole electrical verification handcart, stationary installation and thrust unit can be made by aluminium alloy.Like this can be so that the electrical verification handcart is portable light and handy.
The using method of the electrical verification handcart that provides among following simple declaration the present invention.
At first need the electrical verification handcart is entered the working position, particularly, mention whole instrument, can only mention the instrument rear end in practice, rely on the wheel of front end to move.To be positioned at the left and right rail of two aligner wheels tradition electrical verification handcarts bottom wheels of two ones, and earlier wheel be put into guide rail, with instrument shift onto promote push up the position of electrical verification Men Kaimen link rod after, more whole instrument set level on ground.
Then, the electrical verification handcart is fixed, particularly, the earthing device of the right front bottom of affirmation instrument is fitted with copper earth plate, and the free end of location sheet metal 4 and the cabinet angle steel on ground are offseted, and confirms that stop valve 88 is in closed condition.
Confirm afterwards whether ground connection work, the insulation work of whole electrical verification handcart are finished, and whether the switch of switch cubicle closes a floodgate.
Carry out opening door operation, open electric power device, the electrical verification door can be opened fully up to its driving power device.
Close the electrical verification door, finish electrical verification operation after, at first guarantee safety, control electric power device 1 then thrust unit 2 retracted, the electrical verification door is slowly closed.
The very light in weight of electrical verification handcart integral body provided by the invention, staff's one hand can be mentioned, cooperate electric-powered system, the staff only need press control knob, just can easily the electrical verification door of high-tension switch cabinet be opened, the volume of entire tool is also very little, and structure is simple relatively, and manufacturing cost is also very low.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
