Background technology
Along with the modern propelling of underground mining, hydraulic support is widely used in the supporting of exploitation workplace, and a lot of tests and the Interventions Requested of hydraulic support need to carry out on a special bracket loading test platform.This testing table should have and bears support and comprise the anchorage force (being generally 10000～40000kN) under unbalance loading state, horizontal load capability, the pilot projects such as tail boom, wall supporting, side are protected, base, thrust gear can be provided, should there is the function such as adaptability and data acquisition of lifting the end, turnover frame, adjusting frame, not unit-frame type and height simultaneously.
Traditional is hydraulic bracket test-bed, the majority that is connected between top board and column adopts side jack types, namely on column and upper top board, process respectively circular hole, connect with bearing pin, its shortcoming is that upper top board volume and quality are larger, be difficult to processing, particularly be difficult for keeping the relative-position error of multiple jacks, and larger to its intensity effect after processing, for this is to large work resistance testing table, upper top board, base plate will do to obtain special bulkiness, have plenty of foundry goods of one of ton up to a hundred etc., process more difficultly, and waste is serious.This type testing table alignment pin is stressed bad, when particularly on column and upper top board, circular hole regulates height, is difficult for aligning, and latch is very difficult, generally need to add complicated lifting jack stroke and synchronous control system, has strengthened manufacturing cost and use cost etc.Connection between testing table bottom column and base plate, if bearing pin connects, in process of the test, whole testing table stability is bad, repeated stock, fatiguability is aging, and affects the precision of data acquisition.If fixed by modes such as bolt connections, bolt easily cut off and structure more complicated, there is equally impact fatigue problem etc.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art provides a kind of combination beam pre-stress type hydraulic bracket test-bed, easy to assembly, utilizes prestressing technique, improve support body stability, shortened the process-cycle, reduced equipment cost, when gearshift, insert-pull pin is very convenient.
The utility model comprises column, top board, base plate, it is characterized in that: also comprise entablature, upper longeron, slotted hole, prestressed girder, sill, lower longeron, two entablatures and a upper longeron composition top i-shaped beams, two sills and a lower longeron composition bottom i-shaped beams, top board is fixed on below the i-shaped beams of top, and base plate is fixed on above the i-shaped beams of bottom; The top of four columns arranges some slotted holes, and is connected with the termination of entablature by upper latch, and the bottom of column is provided with a circular hole, is connected with the termination of sill by lower latch, the upper end of column shores by growing, short shore fixing; Four jiaos of jack places of two entablatures are separately installed with four hydraulic bolt mechanisms, connect hydraulicefficiency elevation structure below; Described prestressed girder is two, is fixed on base plate both sides, and two ends are welded on respectively on column.
Horizontal loading apparatus, wall supporting test unit, tail boom test unit, side are protected the equal graftings such as test unit on top board, lift end test unit, pass test unit, pass in and out frame and adjust the equal graftings such as rack device on base plate.
Technique scheme is known, the utlity model has following beneficial effect: 1, adopt upper and lower built H beam and four column composition stress frames, easy to assembly, the upper and lower i-shaped beams of array configuration can be taken independent processing apart, volume is little lightweight, processing is simple, and easily ensures machining high-precision; 2, between column and crossbeam bearing pin, be the connected mode of free beam, stress condition is good; The roll adjustment jack of four columns is slotted hole, and when gearshift, insert-pull pin is very convenient, without the strict stroke of controlling elevating mechanism with synchronize, first, at about medium position jack of slotted hole, after latch puts in place, elevating mechanism is raised to bearing pin the arc top of jack again, easy to operate, roll adjustment jack is simple especially; 3, top board and base plate all deteriorate to similar cushion block, except simple connecting hole, almost few of finishing workload, and should " cushion block " have the reinforcing effects such as the bending resistance of increasing to upper and lower I-shaped bearing beam; 4, easy to assembly, and precision is high, and stressed better; 5, prestressed structure reduces the impact of latch gap rocking in loading procedure, impact and elastic deformation, makes support body stable, and the life-span is long, has improved support body stability, facilitates data acquisition, minimizing distortion; 6, complete machine is lightweight, and processing capacity is few, and device fabrication cost is lower.
