Embodiment
As shown in Figure 1, 2, the present invention includes the frame body 2 of rectangle structure, and 2 one end of frame body, which is transversely slided, to be provided with
Try to stop people from fighting each other seat 1, seat 1 of trying to stop people from fighting each other sets articulation piece 10；Side, which is provided with, on the frame body 2 for trying to stop people from fighting each other 1 one or both sides of seat pushes away jack
9, side pushes away the piston rod of jack 9 and articulation piece 10 is hinged, and the side pushes away 9 cavity of resorption of jack and is connected with one-way lock and safety valve；
The upper surface slide of frame body 2 sets sliding panel 3, has been respectively articulated with push-and-pull jack 4 along longitudinal direction positioned at 2 both sides of frame body, has pushed away
The piston rod of jack 4 is drawn to be hinged respectively with sliding panel 3.It is laterally spaced on frame body 2 to be provided with multiple round steel grooves, each
Round steel 11 is placed with round steel groove, round steel 11 is in rolling contact with 3 bottom surface of sliding panel.
The basic functional principle when present invention is detected is：When both sides push-and-pull jack 4 stretches out, compression hydraulic stent
Advancing jack 7, makes the 7 cavity of resorption pressure rise of advancing jack of hydraulic support, after pressure reaches opening pressure of safety valve, peace
Full valve is opened.Push-and-pull jack 4 can push hydraulic support foundation 6 and move, in the process, the advancing jack 7 of hydraulic support
It is subject to larger pressure all the time with passing frame 8, achievees the purpose that to advancing jack 7 and the experiment of passing frame 8.
When being tested, operated according to following specific steps：
Step 1：The hydraulic support of passing frame 8 for needing to be tested is disintegrated first as shown in Figure 3, leave base 6,
Passing frame 8, advancing jack 7, carried bottom jack 5 and fluid pressure line part（Hydraulic control one-way valve including advancing jack 7, peace
Full valve and manipulation valve）；
Step 2：By base 6 with 3 firm welding of sliding panel, the articulation piece 10 by hydraulic suppor process frame 8 with seat 1 of trying to stop people from fighting each other
Connection.
Step 3：According to the hydraulic system principle figure shown in Fig. 4, the connection of pipe-line system is completed.
Step 4：To the cavity of resorption feed flow of hydraulic support carried bottom jack 5, carried bottom jack 5 can push down passing frame 8, realize
To the Vertical loading of passing frame 8.Meanwhile offside pushes away 9 cavity of resorption feed flow of jack, side pushes away jack 9 and promotes articulation piece 10 lateral
It is moved to untill passing frame 8 contacts with base 6, so as to fulfill lateral loading.Side pushes away 9 cavity of resorption of jack and is connected with one-way lock and peace
Full valve.Side pushes away jack 9 as two in Fig. 2, and the side that either side can be individually enabled according to actual conditions pushes away jack 9, realizes side
To the detection of loading.
Step 5：As shown in figure 3, giving push-and-pull 4 cavity of resorption feed flow of jack, push-and-pull jack 4 stretches out, and promotes sliding panel 3 along vertical
To movement, since the base 6 of test bracket welds together with sliding panel 3, the base 6 of test bracket is also transported therewith
It is dynamic.
Since passing frame 8 and seat 1 of trying to stop people from fighting each other hingedly are fixed, hydraulic support foundation 6 with equipment 3 firm welding of sliding panel,
Therefore when to push-and-pull 4 cavity of resorption feed flow of jack, the thrust of sliding panel 3 and hydraulic support foundation 6 longitudinally rearward, hydraulic pressure branch can be given
Thrust of the meeting of frame base 6 to 7 cylinder body of advancing jack backward, and the piston rod of advancing jack 7 is connected with passing frame 8, is
It is fixed.Therefore, the pressure of 7 cavity of resorption of advancing jack can raise always.
Step 6：Pressure of the advancing jack 7 due to being subject to base 6 and passing frame 8, lower cavity pressure can raise, when reaching
After opening pressure of safety valve, 7 cavity of resorption liquid of advancing jack is discharged the liquid return hole for the system of flowing to, sliding panel 3 and hydraulic support
Base 6 may proceed to it is vertical be moved rearwards, until 7 stroke of advancing jack terminates, complete experiment process.In this process, elapse
Jack 7 and passing frame 8 are under pressure all the time, achieve the purpose that experiment.
This process simulation passing frame 8 is in underground applying working condition.During, power of the passing frame 8 by three directions：Its
One, side, which pushes away jack 9, will promote seat 1 of trying to stop people from fighting each other laterally to load；Second, carried bottom jack 5 pushes down passing frame 8 all the time, realize
To the Vertical loading of passing frame 8；Third, the pressure of base 6 and passing frame 8, makes 7 cavity of resorption liquid of advancing jack in height
It is discharged in the case of pressure.
Step 7：Once after the test, to pushing and pulling 4 epicoele feed flow of jack, while also to stent carried bottom jack 5
Epicoele feed flow, carried bottom jack 5 can leave passing frame 8, and push-and-pull jack 4 can haul base 6 and sliding panel 3 resets, at the same time
For the cavity of resorption filling liquid of advancing jack 7, the emulsion needed for experiment next time is supplemented.
Step 8：4 are repeated the above steps to step 7, test of many times is carried out to passing frame, completes the longevity to passing frame
Life experiment.
So far, entirely experiment process is completed, and is realized laterally and vertical compound additional to hydraulic support pushing mechanism progress
The composite testing of load.
The frame body 2 of the present invention is frame structure, and intensity is higher and manufacture cost is low.The longitudinal load test of passing frame 8
Mainly power is provided by the push-and-pull jack 4 of 2 both sides of frame body come what is completed, which is φ
200mm.In test, relative motion occurs for sliding panel 3 and frame body 2, installs two row round steel 11 additional on 2 surface of frame body, favorably
In reduction frictional force；In order to reduce frictional force, naturally it is also possible to take other common technological means.Side push away jack 9 be to
Passing frame 8 laterally loads, and according to test request, it is 150KN to take the optimal value of the thrust, and side pushes away safety valve pressure optimum setting
It is worth for 32Mpa, it is φ 80mm that side, which pushes away the optimal value of 9 cylinder diameter of jack,.
