Embodiment
As shown in Figure 1, 2, the utility model comprises the frame body 2 of rectangle structure, transversely slides and be provided with seat 1 of trying to stop people from fighting each other in frame body 2 one end, and seat 1 of trying to stop people from fighting each other arranges articulated elements 10; The frame body 2 being positioned at seat 1 one or both sides of trying to stop people from fighting each other is provided with thruster lifting jack 9, and piston rod and the articulated elements 10 of thruster lifting jack 9 are hinged, and described thruster lifting jack 9 cavity of resorption is connected with one-way lock and safety valve; The upper surface slide of frame body 2 arranges sliding panel 3, is positioned at frame body 2 both sides and is longitudinally hinged with push-and-pull lifting jack 4 respectively, and the piston rod of push-and-pull lifting jack 4 is hinged with sliding panel 3 respectively.Frame body 2 is transversely arranged at intervals with multiple round steel groove, in each round steel groove, is all placed with round steel 11, round steel 11 and described sliding panel 3 bottom surface Structure deformation.
Basic functional principle when the utility model detects is: when both sides push-and-pull lifting jack 4 stretches out, the advancing jack 7 of compression hydraulic support, advancing jack 7 times cavity pressures of hydraulic support are raised, and after pressure reaches opening pressure of safety valve, safety valve is opened.Push-and-pull lifting jack 4 can push hydraulic support foundation 6 and move, and in the process, advancing jack 7 and the passing frame 8 of hydraulic support are subject to larger pressure all the time, reaches the object tested advancing jack 7 and passing frame 8.
When testing, operate according to following concrete steps:
Step 1: as shown in Figure 3 first by needing the hydraulic support carrying out the passing frame 8 tested to disintegrate, leaving base 6, passing frame 8, advancing jack 7, lifting end lifting jack 5 and fluid pressure line part (comprising the hydraulic control one-way valve of advancing jack 7, safety valve and control valve);
Step 2: by base 6 with sliding panel 3 firm welding, connects the articulated elements 10 of hydraulic suppor process frame 8 with seat 1 of trying to stop people from fighting each other.
Step 3: according to the hydraulic system principle figure shown in Fig. 4, completes the connection of pipe system.
Step 4: cavity of resorption feed flow hydraulic support being lifted to end lifting jack 5, lifts end lifting jack 5 and can push down passing frame 8, realize the vertical loading to passing frame 8.Meanwhile, to thruster lifting jack 9 cavity of resorption feed flow, thruster lifting jack 9 promotes articulated elements 10 and is moved laterally to till passing frame 8 contacts with base 6, thus realizes side direction and load.Thruster lifting jack 9 cavity of resorption is connected with one-way lock and safety valve.In Fig. 2, thruster lifting jack 9 is two, can enable separately the thruster lifting jack 9 of either side according to actual conditions, realizes the detection that side direction loads.
Step 5: as shown in Figure 3, to push-and-pull lifting jack 4 cavity of resorption feed flow, push-and-pull lifting jack 4 stretches out, and promote sliding panel 3 and move longitudinally, because the base 6 of test bracket welds together with sliding panel 3, therefore the base 6 of test bracket also moves thereupon.
Because passing frame 8 and seat 1 of trying to stop people from fighting each other are hinged fixing, hydraulic support foundation 6 is with sliding panel 3 firm welding of equipment, therefore when to push-and-pull lifting jack 4 cavity of resorption feed flow, can to sliding panel 3 and the longitudinal thrust backward of hydraulic support foundation 6, hydraulic support foundation 6 can to advancing jack 7 cylinder body thrust backward, and the piston rod of advancing jack 7 is connected with passing frame 8, be fixed.Therefore, the pressure of advancing jack 7 cavity of resorption can raise always.
Step 6: advancing jack 7 is owing to being subject to the pressure of base 6 and passing frame 8, lower cavity pressure can raise, after reaching opening pressure of safety valve, advancing jack 7 cavity of resorption liquid is discharged the liquid return hole of the system of flowing to, sliding panel 3 and hydraulic support foundation 6 can continue longitudinally mobile, until advancing jack 7 stroke terminates, complete process of the test.In this process, advancing jack 7 and passing frame 8 are under pressure all the time, reach the object of test.
This process simulation passing frame 8 is at down-hole applying working condition.In process, passing frame 8 is by the power in three directions: one, and thruster lifting jack 9 will promote seat 1 side direction loading of trying to stop people from fighting each other; Its two, lift end lifting jack 5 and push down passing frame 8 all the time, achieve the vertical loading to passing frame 8; Its three, the pressure of base 6 and passing frame 8, makes advancing jack 7 cavity of resorption liquid be discharged under high-pressure situations.
Step 7: after single test terminates, to push-and-pull lifting jack 4 epicoele feed flow, also support is lifted to the epicoele feed flow of end lifting jack 5 simultaneously, lift end lifting jack 5 and can leave passing frame 8, push-and-pull lifting jack 4 can haul base 6 and sliding panel 3 resets, be the cavity of resorption topping up of advancing jack 7 simultaneously, supplement the emulsion needed for test next time.
Step 8: repeat above-mentioned steps 4 to step 7, test of many times is carried out to passing frame, completes the durability test to passing frame.
So far, whole process of the test completes, and achieves and carries out to hydraulic support pushing mechanism the composite testing that side direction loads with vertical compound outward.
Frame body 2 of the present utility model is framed structure, the higher and low cost of manufacture of intensity.The longitudinal load test of passing frame 8 provides power primarily of the push-and-pull lifting jack 4 of frame body 2 both sides, and the best value of this push-and-pull lifting jack 4 cylinder diameter is φ 200mm.In test, there is relative motion in sliding panel 3 and frame body 2, installs two row round steel 11 additional on frame body 2 surface, is conducive to reducing friction force; In order to reduce friction force, other common technological means can certainly be taked.Thruster lifting jack 9 loads to passing frame 8 side direction, and according to test request, getting the best value of this thrust is 150KN, and thruster safety valve pressure optimum setting value is 32Mpa, and the best value of thruster lifting jack 9 cylinder diameter is φ 80mm.
