Load support to include for bracketing at the bearing base 5 of the rectangle of the lower section of filling support, this bearing base 5 extends along the longitudinal direction, on the edge, the left and right sides of bearing base 5, symmetry is equipped with some columns 4, each column 4 is at fore-and-aft direction uniformly at intervals, and it is fixed with rigid bar 2 at the top of each column 4, being provided with the reinforcement diagonal brace 6 being in bearing base 5 left and right sides between adjacent two columns 4, the lower end strengthening diagonal brace 6 is fixed on the bottom of a column 4, upper end is fixed on the top of adjacent upright posts 4.nullRigid bar 2 includes the back timber 21 of framework shape，Back timber 21 left and right sides side bar is erected at above the column 4 of bearing base 5 left and right sides，Before and after back timber 21, the side bar of both sides bridges respectively and is fixed on a left side、Between the end of the right beam，Left、Fixing seat 22 before also bridge joint is fixed with between right two side bars、In fix seat 23 and rear fixing seat 24，Front fixing seat 22、In fix seat 23 and rear fixing seat 24 time interval and arrange，At front fixing seat 22、In fix adjacent bridge joint between the two in seat 23 and rear fixing seat 24 and be fixed with and be set in parallel in a left side、Middle buttress brace 26 in the middle of the beam of the right，Between front fixing seat 22 and front side beam, bridge joint is fixed with and is set in parallel in a left side、Front buttress brace 25 in the middle of the beam of the right，Between rear fixing seat 24 and rear side bar, bridge joint is fixed with and is set in parallel in a left side、Rear buttress brace 27 in the middle of the beam of the right.
Load jack and have three groups and outfan is arranged the most down, three groups load jack and are divided into front jack 31, middle jack 32 and rear jack 33 along the longitudinal direction, front jack 31, middle jack 32 and rear jack 33 are all made up of the jack monomer of a pair symmetrical arrangement, the cylinder body of the most front jack 31 is fixed on seat 22 before being fixed on, the cylinder body of middle jack 32 is fixed on seat 23 in being fixed on, and the cylinder body of rear jack 33 is fixed on seat 24 after being fixed on.Connect on front jack 31, middle jack 32 and rear jack 33 and have the hydraulic means controlling the relatively independent stretching motion of three, this hydraulic means i.e. both can control front jack 31, middle jack 32 and rear jack 33 synchronization action, any one or any two action can also be controlled in front jack 31, middle jack 32 and rear jack 33, and remaining is failure to actuate.
In loading beam 1 is in loading support and front and back extend, loading beam 1 is in the lower section of rigid bar 2, the front loading unit that the front side of loading beam 1 is provided with on the side arm back timber for being pressed on filling support and the rear loading unit on the after-frame back timber being pressed on filling support, this forward and backward loading unit is all the downside of loading beam 1.Connect between front loading unit and front buttress brace 25 and have front anticreep chain 71, connect between rear loading unit and rear buttress brace 27 and have rear defence lock-off chain 72, front anticreep chain 71 and rear defence lock-off chain 72 are all the V-shaped chains being drifted apart from left and right directions from top to bottom, the middle part of chain wear or around being located at above rigid bar, two ends between left and right every be connected on loading beam.On the hinged seat that the lower end of front jack 31 is fixing on the upper side that the axis that left and right extends is hinged on front loading unit, the lower end of middle jack 32 is hinged on the upper side in the middle part of loading beam 1 on fixing hinged seat around the axis that left and right extends, on the hinged seat that the lower end of rear jack 33 is fixing on the upper side that the axis that left and right extends is hinged on rear loading unit.
In the present embodiment, the loading beam 1 of experiment porch designs longer.Because relative to conventional hydraulic support, the after-frame back timber of filling hydraulic support is also subjected to from roof pressure in real work.The most described experiment porch can adapt to the experiment of different top beam length filling hydraulic support by changing loading jack quantity, and the design of this loading beam 1 is adapted to the carrying experiment with the filling hydraulic support of before and after's back timber.Filling hydraulic support can be tested with the form that inside and outside loads, preferably select external load experiment method, by the support force situation of external roof pressure when can simulate real work more really, load mode is jack pressure, it is achieved simulation support is overall and partial pressing's situation.
The operation principle of this experiment porch is: first, filling support is placed on bearing base 5, load support setting prop to certain altitude, the manipulation valve of hydraulic means operates simultaneously, the height of loading beam 1 adjusts height with the telescopic variation loading jack and loads, and each operation valve is fine-tuning, to keep loading beam 1 level, side arm back timber and after-frame back timber to filling support pressurize, and simulate the operating mode of filling set cap entirety pressurized；Also can individually finely tune each or two jack monomers simultaneously, make filling hydraulic support top beam local compression, simulate back timber local compression situation with this, in place of being different from conventional hydraulic support experiment porch just, by local loading, can realize the simulation experiment of back timber after filling hydraulic support.This is due to filling support after-frame back timber roof pressure to be born in real work, therefore back timber after filling support is tested, this is a kind of brand-new design, it is different from conventional stent experiment porch, the stressing conditions of back timber after can simulating accurately, and carry out force analysis, be conducive to the most perfect to its mechanism.By installing various digital collection instrument on experiment porch, Pressure gauge gather each stress point stress change information.Secondly, experiment porch is applicable to the filling support in girdle work, it is applicable to the loading of long back timber, external pressurized is carried out by the loading jack pair long back timber of filling support being arranged on long loading beam 1, as a example by accompanying drawing, it is mounted with six jack monomers, length and the number of jack monomer of loading beam 1 can be designed according to the length of filling support, by handling valve events, carry out the simulation test of long bar timber.Being directed to filling hydraulic support, this experiment porch can test compacting apex distance and compacting angle, thus reinforcement mechanism is optimized improvement, designs the more preferable reinforcement mechanism of performance.
In the above-described embodiments, in hydraulic means, the oil circuit control of each jack monomer is relatively independent, to realize the control respectively to each jack monomer, in other embodiments, can also be by same oil circuit, the mode that simply each jack monomer corresponding is respectively provided with controlled valve in oil circuit exit position realizes the control respectively to each jack monomer, naturally it is also possible to the mode using other oil circuits to control realizes the control respectively to each jack monomer.It addition, the chain of anticreep chain not only can use V-shaped, it would however also be possible to employ splayed.Before, during and after and, jack all uses a pair jack monomer to be the perpendicularity in order to obtain downward pressure, it is to avoid deflection occurs in downforce, in other embodiments, it is also possible to realize vertical force by guiding mechanism between loading beam and rigid bar.
