Description

Technical Field

[0001] The present invention relates to the technical field of gate testing, and in particular to an automatic testing device for bearing capacity of a flood prevention gate for a building and a use method thereof. Background Art

[0002] The flood-proof gate for buildings is also called the fully automatic flood-proof gate for buildings with water power. "Fully automatic with water power" means that the gate is opened automatically by the buoyancy of water level changes. It can also be opened by electric, hydraulic, air pressure, etc. The flood-proof gate can be divided into light, ordinary and heavy types according to the bearing capacity of the door leaf in the closed state. The light type is used for the entrances and exits of ground buildings or underground buildings where many micro and small motor vehicles pass slowly or where people and non-motor vehicles pass, such as underground garages, subway stations, underground commercial streets, etc. The ordinary type is used for the entrances and exits of roads where many medium-sized motor vehicles pass slowly, such as medium and small parking lots on the ground. The heavy type is used for the entrances and exits of roads where many large and heavy motor vehicles pass slowly, such as freight stations, factory areas, etc. The installation forms of flood-proof gates are surface type and underground type. The surface flood-proof gate shall not be higher than the ground by more than 50mm as a whole. The width of the flood-proof gate shall not exceed 10m and the height shall not exceed 1.5m.

[0003] Regardless of the installation form and size, the anti-flood gate must meet the specified load-bearing capacity when in the closed state. The light test load is 125kN, the ordinary type is 250kN, and the heavy type is 400kN. The loading equipment applies the test load at a rate of 1kN / s to 5kN / s and maintains it for not less than 30s. After the load test, the anti-flood gate should not have cracks, severe deformation, opening and closing jams, or other damage that affects its use function.

[0004] Since the anti-flood gates are customized according to the actual site and their dimensions vary, the existing equipment cannot meet the requirements for installing large-sized anti-flood gates for bearing capacity testing. The current test process requires manual control of loading, timing and judgment, and the test quality and efficiency are not high.

[0005] To this end, the present application designs an automatic testing device for the bearing capacity of flood-proof gates for buildings and a method for using the same to solve the above-mentioned problems. Summary of the invention

The two pads B (22) are used to support the long sides of the anti-flood gate sample (4) and are hinged to the gate, and can also fix the opening and closing device of the gate; S3, placing an elastic pad (29) just below the pressure sensor (31), i.e., at the center of the upper surface or the water-facing surface of the anti-flood gate sample (4), and placing a rigid pad (30) on the upper surface of the elastic pad (29); S4, inputting the category code of the flood control gate sample (4), including light type, ordinary type, and heavy type, into the PLC controller (15) connected to the display screen, and pressing the test start button; S5, each electronic control component enters the working state, the PLC controller (15) connected to the display screen controls the servo motor (19) to work, and drives the open plug ring (14) at the end of the beam (24) to rotate counterclockwise with the vertical center line of the cylinder (10) as the center through gear meshing. When the open plug ring (14) is inserted into the groove (28), the PLC controller (15) connected to the display screen controls the servo motor (19) to stop; S6, the PLC controller (15) connected to the display screen controls the servo electric cylinder (33) to work, the telescopic end (32) extends, the lower surface of the pressure sensor (31) contacts the upper surface of the rigid pad (30), so that the pressure sensor (31) is applied to the type load at a rate of 1 kN / s to 5 kN / s and maintained for not less than 30 seconds, and the monitoring camera B (34) transmits image data of whether the flood control gate sample (4) has cracks and severe deformation to the PLC controller (15) connected to the display screen; S7, the PLC controller (15) connected to the display screen controls the above components to run in the reverse direction, so that the split insert ring (14) is disengaged from the groove (28) until the crossbeam (24) is parallel to the T-slot ground rail A (2); S8, the PLC controller (15) connected to the display screen controls the operation of the multi-section electric cylinder (37) to open and close the tested anti-flood gate sample (4), and the monitoring camera A (11) and the monitoring camera B (34) transmit images of whether there is opening and closing, blocking, or other damage that affects the use function to the PLC controller (15) connected to the display screen. Finally, the PLC controller (15) connected to the display screen automatically makes a conclusion on the bearing capacity test of the anti-flood gate sample (4) according to the program.
