[0029] This application provides a device for measuring the opening and closing function of a reverse-push flow-blocking gate.

[0030] like Figure 1 As shown, a device for measuring the opening and closing function of a reverse-thrust flow-blocking gate includes:

[0031] Support 1 serves as the base for the entire measuring device.

[0032] A connecting plate 12 is slidably mounted on a bracket 1. The connecting plate 12 is provided with a first mounting seat 5 and a second mounting seat 51. The first mounting seat 5 and the second mounting seat 51 are respectively used to install the left front hinge support and the right front hinge support of the flow-blocking door. The first mounting seat 5 and the left front hinge support are rotatably hinged, and the second mounting seat 51 and the right front hinge support are hinged.

[0033] A support beam 11 is provided, the bottom end of which is fixed to the bracket 1. A hanging structure 6 is provided on the support beam 11, and the hanging structure 6 is used to connect the end of the pull rod on the flow barrier away from the flow barrier.

[0034] A drive assembly is mounted on the bracket 1, and the output end of the drive assembly is connected to the connecting plate 12. The drive assembly is used to drive the connecting plate 12 to slide along the first direction on the bracket 1.

[0035] The push-pull force sensor 10 is used to detect the push-pull force on the connecting plate 12 when it slides on the bracket 1.

[0036] In this application, the installation method of the flow-blocking gate on the connecting plate 12 and the supporting beam 11 simulates the connection of the flow-blocking gate on the reverse thrust component. By driving the connecting plate 12 to slide back and forth on the bracket 1, the movement of the flow-blocking gate during the reciprocating movement of the connecting plate 12 simulates the opening and closing process of the flow-blocking gate on the reverse thrust component. The force on the connecting plate 12 during the sliding process reflects the tension and thrust of the flow-blocking gate during the opening and closing process. By observing the opening and closing process of the flow-blocking gate and the force on it during the opening and closing process, the normality of the flow-blocking gate's opening and closing can be analyzed. The opening and closing test of the flow-blocking gate in the reverse thrust component state can be predicted in advance to determine whether the problem and risk can be qualified. Problems and risks are addressed in advance, and maintenance and debugging can be carried out in advance for faults. Problems such as opening and closing failures or insufficient tension and thrust that may occur in the later large components can be solved in the small component state. This reduces the debugging problems and quality risks in the replacement of parts and assembly process caused by disassembly and troubleshooting, thereby improving the assembly efficiency and pass rate of the reverse thrust component.

[0037] The bracket 1 is provided with a guide rail 4 arranged along a first direction. The guide rail 4 is provided with a sliding slide 13. The connecting plate 12 is slidably mounted on the guide rail 4. The connecting plate 12 is provided with a through hole. The slide 13 is provided with a push block passing through the through hole. Push-pull force sensors 10 are provided on opposite sides of the push block. The slide 13 is connected to the output shaft of the drive assembly. The push block transmits the power from the drive assembly to the connecting plate 12 through the detection end of the push-pull force sensor 10. The inner wall of the through hole and the side facing the detection end of one of the push-pull force sensors 10 are the first abutment surfaces 91, and the inner wall of the through hole and the side facing the detection end of the other push-pull force sensor 10 are the second abutment surfaces 92.

[0038] In this embodiment, the detection ends of the two push-pull force sensors 10 are equipped with fixing screws, and adjusting nuts 9 are sleeved on the outer periphery of the fixing screws. The length direction of the fixing screws is parallel to the first direction. One adjusting screw is located between one of the push-pull force sensors 10 and the first contact surface 91, and the other adjusting screw is located between the other push-pull force sensor 10 and the second contact surface 92. After the slide block 13 and the sliding plate are assembled, the adjusting nuts 9 are rotated so that the distance between the two adjusting nuts 9 and their respective contact surfaces is less than or equal to 0.2 mm. The push-pull force sensor 10 is model STB961, which can display the measured value and peak value in real time. The display of the push-pull force sensor 10 is customized on the front end of the connecting plate 12 for easy reading of the push and pull force values.

[0039] The drive assembly includes a ball screw 8, the screw of which is rotatably mounted on a bracket 1. The lead screw of the ball screw 8 is arranged along a first direction. The nut of the ball screw 8 is fixedly connected to a slide block 13. A handwheel 2 is fixed to one end of the lead screw of the ball screw 8. The movement direction of the slide block 13 is controlled by rotating the handwheel 2 counterclockwise and clockwise.

[0040] The first mounting base 5 and the second mounting base 51 are slidably mounted on the connecting plate 12. The sliding direction of the first mounting base 5 and the second mounting base 51 is perpendicular to the first direction to accommodate the distance between the left front hinge support and the right front hinge support of different flow-blocking doors. Specifically, two sliding grooves are formed on the connecting plate 12, and the length direction of the sliding grooves is perpendicular to the first direction. A fixing bolt passes through one sliding groove to mount the first mounting base 5 on the connecting plate 12, and another fixing bolt passes through the other sliding groove to mount the second mounting base 51 on the connecting plate 12. The distance between the first mounting base 5 and the second mounting base 51 can be adjusted by adjusting the position of the fixing bolts in the sliding grooves.

[0041] The connecting plate 12 is provided with a first auxiliary support block 7 and a second auxiliary support block 71, which are used to support the limiter support on the flow barrier.

[0042] The first auxiliary support block 7 and the second auxiliary support block 71 are detachably mounted on the connecting plate 12 by bolts, and the bolts and the connecting plate 12 are threaded together. The detachable nature of the first and second auxiliary support blocks 7 and 71 allows for easy replacement with different shapes to accommodate the different surface shapes of the limiter supports for different flow-blocking gates. Rotating the bolts relative to the connecting plate 12 adjusts the height of the first and second auxiliary support blocks 7 and 71 to accommodate different heights of the limiter supports for different flow-blocking gates. The bolts pass through the bottom of the connecting plate 12 and connect the first and second auxiliary support blocks 7 and 71.

[0043] The bracket 1 has a first graduated line 15 and a second graduated line 16 spaced apart. The slide 13 or the connecting plate 12 has a marking line 14. When the connecting plate 12 is in the initial position, the marking line 14 is aligned with the first graduated line 15. When the connecting plate 12 is in the end position, the marking line 14 is aligned with the second graduated line 16. The distance between the first graduated line 15 and the second graduated line 16 along the first direction is 814 mm.

[0044] The movement distance of the connecting plate 12 is precisely controlled by scribing and marking lines 14.

[0045] The connecting plate 12 has a socket, and the bracket 1 has a corresponding slot. A pin 3 is detachably installed in the slot, passing through the socket. When the pin 3 passes through the socket and is inserted into the slot, the connecting plate 12 is in its initial position. The driving device controls the connecting plate 12 to move until the pin 3 aligns with the socket, inserting the pin 3 to position the connecting plate 12 at its initial position. After the initial position of the connecting plate 12 is determined, the pin 3 is removed, and the driving device is activated, moving the connecting plate 12 towards its final position. The slot gradually expands from bottom to top to facilitate the insertion of the pin 3.

[0046] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
