Background technology
Electric block is as a kind of easy hoisting machinery, because it has compact conformation, little from heavy and light, overall dimensions, and advantages such as simple to operate, applicability is strong and day by day be subject to user's favor have been widely used in the fields such as port and pier, metallurgical manufacturing, building industry, electric power facility, mining excavation and general manufacturing at present.The safe operation of electric block is that production operation normally moves, the assurance of equipment property safety and operating personnel's personal safety, is a important step in electric block research and development and the factory inspection process for the usability of electric block and the compbined test evaluation in life-span therefore.
Present test platform generally can only be realized the partial test project of electric block, and great majority can not be finished hill climbing test or durability test.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of Multiproject electric hoist test bed is provided, this testing table can satisfy the examination requirements of electric block entry.
According to technical scheme provided by the invention, a kind of Multiproject electric hoist test bed, comprise two parallel entablatures that are fixed on the column, hang under two described entablatures and be fixed with longitudinally track, one end of described track is provided with fixed pulley, and the counterweight counterweight is connected on the electric block by described fixed pulley.
The two ends of described track are provided with dismountable block.
Described track has two, is respectively a light rail and a heavy rail.
Hang between two described entablatures and be fixed with operating corridor, an end of described operating corridor links to each other with ground by stair.
Described operating corridor is between two described tracks.
Also be provided with at least between two described entablatures other one link to each other with described track pass through the entablature that column fixes on the ground.
Be provided with the counterweight shallow hole on the ground between the described column, be provided with the counterweight dell in the described counterweight shallow hole.
The column spacing in described dell district is less than the column spacing in described shallow hole district.
The direction that hoists of described electric block is provided with displacement sensor for pull rope.
The trolley travelling direction of described electric block is provided with two light sensation sensors.
Compared with the prior art the present invention has the following advantages: the present invention becomes the gravity of counterweight counterweight by fixed pulley the resistance of electric block traffic direction, is used for the hill climbing test of electric block; The present invention disposes two kinds of counterweight melt pits of the depth, and shallow hole is used for conventional test, and dell is used for life-span and lifting altitude test, has reduced the ground input; The present invention adopts two Suspension Techniques, hangs the track of two kinds of different sizes under entablature, when satisfying the electric block of different tonnages, has reduced equipment investment.The present invention is simple, compact and reasonable for structure, can cover each pattern electric block below 32 tons, has improved the service efficiency of testing table.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Embodiment
The present invention is further illustrated below in conjunction with the embodiment in the accompanying drawing.
Among Fig. 1, Fig. 2, comprise ground 1, column 2, entablature 3, heavy rail 4, light rail 5, counterweight counterweight 6, fixed pulley 7, operating corridor 8, stair 9, shallow hole 10, dell 11 etc.
As shown in Figure 1 and Figure 2, the present invention is a kind of Multiproject electric hoist test bed, mainly comprises column 2 and entablature 3.Column 2 has four at least, is arranged in the both sides of length direction of rectangle pilot region and fixing with ground 1.Be fixed with respectively an entablature 3 on two root posts 2 of each side, these two entablatures 3 be arranged in parallel.3 times suspensions of two entablatures are fixed with longitudinally track, and an end of track is provided with fixed pulley 7, and counterweight counterweight 6 is connected on the electric block by fixed pulley 7.The gravity of counterweight counterweight 6 is become the resistance of electric block traffic direction by fixed pulley 7, be used for finishing hill climbing test.
Entablature adopts two suspension design for 3 times, and the track of suspension has two, is the track of different model specification, is respectively a light rail 5 and a heavy rail 4.Two tracks can satisfy the electric block test of different tonnages, have reduced equipment investment, and light rail 5 satisfies the electric block test below 5 tons, and heavy rail 4 satisfies the electric block test below 32 tons.
The two ends of track are provided with dismountable block, not slippage from the track when guaranteeing the smooth installation of electric block and test.
Hang between two entablatures 3 and be fixed with operating corridor 8, an end of operating corridor 8 links to each other with ground by stair 9, makes things convenient for the staff to overhaul.Operating corridor 8 is preferably between two tracks.
Also be provided with at least between two entablatures 3 other one link to each other with track pass through the entablature 3 that column 2 fixes on the ground.Improve the rigidity of test tracks by the number that increases entablature 3 and column 2.
Ground between column 2 is provided with the counterweight melt pit, and the counterweight melt pit divides shallow hole 10 and dell 11, and dell 11 is positioned at shallow hole 10.Shallow hole 10 is used for conventional test, and dell 11 is used for life-span and lifting altitude test, and counterweight counterweight 6 places melt pit, has reduced the ground input.Dell 11 districts will be used for durability test, so the column spacing in dell 11 districts is less than the column spacing in shallow hole 10 districts.
The direction that hoists of electric block is provided with displacement sensor for pull rope.By displacement sensor for pull rope, obtain in real time the relation of displacement and time, can calculate fast lifting velocity and braking glide quantity.
The trolley travelling direction of electric block is provided with two light sensation sensors.Measure mistiming and the distance of the light sensation sensor travelling speed that can fast calculate dolly of dolly by two light sensation sensors.
Testing table provided by the invention can select different counterweights to carry out the test of each pattern electric block below 32 tons, can realize the test such as lifting capacity, pulling speed, travelling speed, braking glide quantity, zero load, dynamic load, static load, climbing, life-span of electric block.The present invention is simple, compact and reasonable for structure, can cover each pattern electric block below 32 tons, has improved the service efficiency of testing table.
