Abstract
The present invention discloses a lifting crane in an electric power system, comprising a plurality of pillars, a load-bearing frame, a guide rail, a parallel moving mechanism, and a manual sling. The load-bearing frame is detachably fixed on a transformer, a JP cabinet, or two supporting shelves on the upper end of a big measuring box. The plurality of pillars are detachably fixed together. The lower end of the lowest pillar is inserted in a positioning sleeve of a chassis. The guide rail is detachably fixed between the upper end of the highest pillar and the load-bearing frame. The parallel moving mechanism is slidably mounted on the guide rail. The lower end of the parallel moving mechanism is mounted with the manual sling. The lifting crane is easy in disassembly, light in weight, easy to transport and carry, easy to transport even in small space and a mountain area, fast in operating speed, and low in labor intensity.
Description
Technical field
The present invention relates to the lift heavy instrument of the electrical equipments such as a kind of installation, dismounting and change voltage transformer, JP cabinet, large batch meter.
Background technology
In the National Power System, industry, agricultural, civilian power taking all depend on the voltage transformer of all size, and the disassembling, assembling and replacing of voltage transformer is one of to work very frequently.Along with the fast development of China's economic construction, the renewal of consumer, the voltage transformer of a lot of original operations can not be suitable for and must change or increase-volume.Since historical reasons, some region house owed by a citizen amplification, and blocking channel causes the mechanical equipment of lifting can not enter the scene; In the mountain area, the lifting of voltage transformer is troubling old problem equally, and the mechanical equipment of lifting also is difficult for entering the scene; These occasions can only be taked manually slowly to dismantle voltage transformer by instruments such as ropes, and operating speed is slow, and labour intensity is high, and are dangerous large.No matter adopt traditional lifting machine equipment or artificial unloading's voltage transformer, all be easy to cause the generation of the colliding with of voltage transformer, displacement and the hidden danger such as out of control.
Summary of the invention
Purpose of the present invention solves the above-mentioned problems in the prior art exactly, and lifting hoisting crane, this hoisting crane easy accessibility in a kind of electric system is provided, lightweight, transportation, easy to carry is even if also be convenient to transportation at narrow space and mountain area, operating speed is fast, and labour intensity is low.
For achieving the above object, technical solution of the present invention is: lifting hoisting crane in a kind of electric system, and it comprises many pillars, bearing frame, guide rail, parallel moving mechanism and manual hoist cable; Bearing frame removably is fixed on two bracing frames of voltage transformer, JP cabinet or large batch meter upper end; Many pillars removably are fixed together, and nethermost pillar lower end is plugged in the locating bush on chassis; Guide rail removably is fixed between the upper end and bearing frame of the top pillar; Parallel moving mechanism is slidably mounted on the guide rail, and the parallel moving mechanism lower end is equipped with manual hoist cable.
The present invention also comprises the multilayer pull bar, and every layer of pull bar is comprised of pull bar A and pull bar B, and the end of pull bar A and pull bar B removably is fixed on respectively on two bracing frames of voltage transformer, JP cabinet or large batch meter, and the other end removably is fixed on the pillar.
Parallel moving mechanism described above is for to affect the mobile cucurbit that moves forward and backward by steel rope.
Manual hoist cable described above is the suspension hook that guide chain pulls.
Each parts of the present invention all are detachable fixable individual components, and during transportation, each parts is in bulk on transport trolley, and its volume is little, and is lightweight, and transportation, easy to carry is even if also be convenient to transportation at narrow space and mountain area.During use, each parts is fixed on together in order gets final product, two bracing frames of pillar and bearing frame and voltage transformer, JP cabinet or large batch meter form firm three-point support structure, parallel moving mechanism and manual hoist cable form again very easily translation and reciprocating mechanism, after as long as the voltage transformer that will need to change, JP cabinet or large batch meter are pulled down, be hung on the manual hoist cable, by parallel moving mechanism move to make things convenient for the position after, be transported to ground, again new voltage transformer, JP cabinet or large batch meter are lifted up to install and get final product, it is very easy to use.Its installing/dismounting is quick, and operating speed is fast, and labour intensity is low, and can not cause the generation of the colliding with of voltage transformer, displacement and the hidden danger such as out of control.
Description of drawings
Fig. 1 is mounting structure schematic diagram of the present invention.
As shown in Figure 1, the present embodiment comprises four pillars 21,22,23 and 24, bearing frame 6, guide rail 4, parallel moving mechanism, manual hoist cable and two-layer pull bar.Parallel moving mechanism is for to affect the mobile cucurbit 51 that moves forward and backward by steel rope 54, and manually hoist cable is the suspension hook 52 that guide chain 53 pulls.Bearing frame 6 two ends are bolted on the two cement bracing frames 91 and 92 of voltage transformer, JP cabinet or large batch meter upper end.Peg graft and are fixed together in four pillars 21,22,23 and 24 ends, following pillar 21 lower ends place in the locating bush on chassis 1.Guide rail 4 two ends are bolted on the upper end and bearing frame 6 of pillar 24 in the above.Affect the mobile cucurbit 51 that moves forward and backward to be slidably mounted on the guide rail 4 by steel rope 54, steel rope 54 1 ends are fixed on the mobile cucurbit 51, fall to the position of lower end staff stretchy behind the pulley 31 and 32 of the other end by guide rail 4 two ends.Mobile cucurbit 51 lower ends are equipped with the suspension hook 52 that is pulled by guide chain 53.Every layer of pull bar is comprised of pull bar A 81 and pull bar B 82, and the end of pull bar A 81 and pull bar B 82 is bolted on the two cement bracing frames 92 and 91 of voltage transformer, JP cabinet or large batch meter, and the other end is bolted on two pillars 21 and 24.Like this, four pillars and bearing frame and two cement bracing frames form firm three-point support structure, and four pillars are supported on the two cement bracing frames by two-layer pull bar tension again, the present invention are supported more solid and reliable.7 is voltage transformer, and 10 is the Comprehensive Control case.
Four pillars 21 of embodiment described above, 22,23 and 24 also can be bolted by the flange of strut ends welding or integrative-structure is in the same place.
The present embodiment installation, dismounting, convenient transportation, simple to operate.Can make 1.8 meters of the weight parallels of dismounting, lift heavy can reach 3 tons up and down, and effective travel can reach 3 meters, can operation in the environment of narrow and small less than 3 square meters in region.
Above-described embodiment only is preferred and exemplary, and those skilled in the art for example can according to the description of this patent, adopt the parallel moving mechanism of other structure and the manual hoist cable of other structure; Use the pull bar of the pillar of other radical and other level or do not use pull bar according to the needs of voltage transformer, JP cabinet or large batch meter height.It is all covered by the protection domain of this patent.
