Technical field
The utility model relates to a kind of hydraulic lift, has related in particular to a kind of two fork hydraulic elevation type tool car.
Background technology
The existing most structure of tool car that is used for electrical switchgear is fixed, and efficient is low during the inspection switch cabinet breaker, and also comparatively inconvenience of its carrying, up-down, fitting operation, is difficult to satisfy the constantly needs of development of switch cubicle.Therefore, be necessary the structure of existing tool car is optimized.
Summary of the invention
The purpose of the utility model provides a kind of compact conformation, intensity is good, stability is high, is easy to install, transportation, easy to operate two fork hydraulic elevation type tool cars.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
Two fork hydraulic elevation type tool cars comprise frame, and frame is provided with hydraulic means, two yoke expansion bracket and goes up lower guideway, and hydraulic means is connected with two yoke expansion brackets, and upper rail, lower guideway flexibly connect with two yoke expansion brackets respectively.Frame top is provided with pallet, and pallet can fast be changed according to the circuit breaker of different size, and needn't dispose new hydraulic lift.Be designed with spacing hole in the piston cylinder of hydraulic means, when piston stroke puts in place, can its piston cylinder communicated with oil tank through spacing hole, step on the rising rocking bar so again, tool car also can not rise, and reaches spacing purpose.
As preferably, described pair of yoke expansion bracket comprises first bow and second bow, and an end and the upper rail on the said first bow top are affixed, and the other end is connected with the upper rail rolling through pulley; One end and the lower guideway of the said second bow bottom are affixed, and the other end rolls with lower guideway through pulley and is connected.
As preferably, described frame rear end is provided with rising rocking bar and following decompression board, and said rising rocking bar links to each other with hydraulic means.
As preferably, directional wheel is installed below the described frame front end, the frame rear end below is equipped with universal wheel.
As preferably, the front end of described pallet is provided with lock crook plate and lead.
The utility model has significant technique effect owing to adopted above technical scheme:
The utility model can be realized exchanging easily to two circuit breakers about the double-deck breaker cabinet, makes the faster convenience of switch cubicle maintenance circuit breaker, the fail safe of improve maintenance, carrying, going up and down, a kind of product of special research and development.This product with compact structure, intensity is good, stability is high, is easy to installation, transportation, characteristics such as easy to operate, has satisfied the demand of switch cubicle development, has very high practicality.
Description of drawings
Fig. 1 is the working state structure sketch map of the utility model.
Fig. 2 is the non operating state structural representation of the utility model.
The toponym that each number designation referred in the above accompanying drawing is following: wherein 1-frame, 2-hydraulic means, 3-two yoke expansion brackets, 4-lower guideway, 5-pallet, 6-upper rail, 7-rising rocking bar, 8-following decompression board, 9-lock crook plate, 10-lead, 11-directional wheel, 12-universal wheel, 31-the first bow, 32-the second bow.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing 1 to accompanying drawing 2:
Two fork hydraulic elevation type tool cars, as shown in Figure 1, comprise frame 1; Frame 1 is provided with hydraulic means 2, two yoke expansion bracket 3 and lower guideway 4; Hydraulic means 2 is connected with two yoke expansion brackets 3, and frame 1 top is provided with pallet 5, and the front end of pallet 5 is provided with lock crook plate 9 and lead 10.Pallet 5 bottoms are provided with upper rail 6, and said upper rail 6, lower guideway 4 flexibly connect with two yoke expansion brackets 3 respectively.
Two yoke expansion brackets 3 comprise first bow 31 and second bow 32, and an end and the upper rail 6 on said first bow 31 tops are affixed, and the other end rolls with upper rail 6 through pulley and is connected; One end and the lower guideway 4 of said second bow 32 bottoms are affixed, and the other end rolls with lower guideway 4 through pulley and is connected.Frame 1 rear end is provided with rising rocking bar 7 and following decompression board 8, and said rising rocking bar 7 links to each other with hydraulic means 2.Frame 1 front end below is equipped with directional wheel 11, and below, frame 1 rear end is equipped with universal wheel 12.
As shown in Figure 2, when the hydraulic pressure tool car is in extreme lower position, circuit breaker is placed on the hydraulic pressure tool car, because the position is lower, liftoff only 320 millimeters height are carried circuit breaker easily and safely off.Promote the switch cubicle dead ahead of hydraulic pressure tool car then,, step on rising rocking bar 7 with cabinet centering to appointment; Slowly rise; As shown in Figure 1 during to the needs height, promote the hydraulic pressure tool car, its lead 10 is inserted in the location hole of switch cubicle; Lock crook plate 9 locks with switch cubicle simultaneously, carries out the forward operation of circuit breaker then.
Release operation, shift tool car onto switch cubicle before, with cabinet centering; Step on rising rocking bar 7, when slowly rising to when needing height position as shown in Figure 1, promote the hydraulic pressure tool car; Its lead 10 is inserted in the location hole of switch cubicle, and lock crook plate 9 and switch cubicle locking are pulled out circuit breaker then to tool car simultaneously; Both sides latch on the circuit breaker chassis inserts in the hole of tool car, stirs the other end lever of lock crook plate 9 then, and its lock crook plate 9 is unlocked with switch; Pulling hydraulic pressure tool car separates with cupboard, steps on decompression board 8 down then, makes its slow decline.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
