Hydraulic bracket test-bed is a kind of equipment that technical feature and security performance to hydraulic support detect and test, continuous development along with the coal in China industry, the specification of hydraulic support is also more and more, hydraulic bracket test-bed for certain load-bearing capacity needs to satisfy the hydraulic support of more specifications.Current common hydraulic bracket test-bed base, the position loading bench between back timber, base and the back timber at two column frames, fixedly connected two column frame tops and drive the loading bench hoist cylinder that moves up and down thereon that comprises.Column frame is made of some groups of cant beams between two columns and two columns, is provided with first pin shaft hole that several realize the loading bench location on column from top to bottom, and loading bench and column mating part are equipped with second pin shaft hole and bearing pin plug-in and pull-off device.Apart from definite, for guaranteeing hydraulic bracket test-bed specified load-bearing capacity, alignment pin must satisfy certain dimensional requirement to the span of above-mentioned hydraulic bracket test-bed rising or decline, causes column upper pin pitch-row not reduce by adjacent holes on the column.For the hydraulic support of the specification between two pitch-rows, above-mentioned hydraulic bracket test-bed can not satisfy detect and test request.
Summary of the invention
The utility model provides a kind of easy to operate for solving the technical matters that exists in the known technology, and can satisfy hydraulic bracket test-bed that plurality of specifications requires.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of hydraulic bracket test-bed, comprise base, vertical fixing is in the base both sides and over against two column frames that are provided with respectively, the back timber at fixedly connected two column frame tops, be arranged at the weighted platform between base and the back timber, and drive the hoist cylinder that weighted platform moves up and down, described column frame structure is made of two columns and some groups of cant beams being arranged between two columns, described column is provided with several first pin shaft holes of realizing the weighted platform location from top to bottom, described weighted platform and described column mating part are equipped with second pin shaft hole and bearing pin plug-in and pull-off device, it is characterized in that: described second pin shaft hole is two up and down, and the distance between two holes is 1.5 times of adjacent holes distance on the column.
The utility model can also adopt following technical scheme:
Described bearing pin plug-in and pull-off device is two covers up and down, corresponding with described up and down second pin shaft hole respectively, described bearing pin plug-in and pull-off device comprises plug oil cylinder, the flanged (FLGD) sleeve in two ends and bearing pin, sleeve one end is fixed on the weighted platform, and it is concentric with second pin shaft hole, the other end of sleeve is concentric fixing with the plug oil cylinder, and the push rod end of oil cylinder extend in the sleeve, and fixedlys connected with bearing pin.
The cylinder barrel end of described hoist cylinder is fixed on the described column, and the push rod end of oil cylinder is fixed on the weighted platform.
Advantage and the good effect that the utlity model has are: at weighted platform and the setting of column mating part two pin shaft holes up and down, and two pin shaft holes are apart from being 1.5 times of pin shaft hole distance on the column.When the pin shaft hole on the weighted platform and the pin shaft hole on the column at once, the bearing pin plug-in and pull-off device is realized the location of weighted platform in this position, another pin shaft hole on the loading bench is positioned on the column middle part of two adjacent pin shaft holes, like this, weighted platform moves up or down pitch-row half, just can realize the location of loading bench, with respect to known equipment, span reduces half, and the specification of triable hydraulic support doubles.
