Description

Technical Field

[0001] The invention relates to the field of bridge experiments, and in particular to a bridge static load experiment simulation pressurization experiment device. Background Art

[0002] Bridge static load test simulation pressurization test equipment is a device specially used for bridge static load test. It can simulate the pressure that the bridge bears in actual use and evaluate its structural performance and safety, providing important reference for the design, construction and maintenance of the bridge.

[0003] The Chinese patent with the publication number "CN116026541A" discloses "a bridge static load test simulation pressurization device, which includes a base, a pressurization mechanism and a fixing mechanism, the pressurization mechanism is arranged on the base, and the fixing mechanism is arranged on the base for connecting the base and the bridge deck". Although it can achieve the effect of "facilitating transportation, shortening transportation time, thereby improving work efficiency, reducing waste of manpower or equipment resources, reducing work costs, facilitating operation, shortening the time for manual connection of the pressurization plate and the connecting plate, and reducing the separation of the connecting plate and the pressurization plate during the work process", the device is an integrated structure when in use. The size of the equipment and the pressurized drive part of the equipment are fixed. When testing the bridge deck with different inclination angles, the pressurized angle of the equipment is fixed and cannot be adjusted in time. When pressurized tests are required at different positions on the front, back, left and right of the bridge deck, the position of the pressurized test cannot be adjusted in time, which is inconvenient for adjustment during the pressurized test, thereby reducing the bridge test effect. In addition, the number of pressurized drives of the equipment is also fixed. When testing on bridges of different sizes, the number of pressurized drives cannot be adjusted.

[0031] In this embodiment, the lifting support structure 2 includes a hydraulic cylinder 3, a hydraulic support rod 4, a rotating mounting seat 5, a rotating mounting rod 6 and a telescopic sleeve rod 7. The hydraulic cylinder 3 is fixedly installed on the inner top of the main support rod 1, the hydraulic support rod 4 is movably installed on the upper end of the hydraulic cylinder 3, the rotating mounting seat 5 is fixedly installed on the upper end of the hydraulic support rod 4, the rotating mounting rod 6 is movably installed on the outside of the rotating mounting seat 5, and the telescopic sleeve rod 7 is movably sleeved on the end of the rotating mounting rod 6 away from the rotating mounting seat 5. The telescopic sleeve rod 7 is telescopically and movably installed by being sleeved on the outside of the rotating mounting rod 6.

[0032] In this embodiment, the hydraulic support rod 4 passes upward through the top of the main support rod 1, the rotating mounting rod 6 rotates around the rotating mounting seat 5, and the two ends of the reinforcement rod 8 are fixedly connected to one end of the front and rear telescopic sleeve rods 7.

[0034] In this embodiment, the telescopic positioning structure 18 includes a telescopic vertical rod 19, a bottom rotating shaft 20, a guide plate 21, a guide groove 22, a clamping plate 23 and a clamping screw 24. The telescopic vertical rod 19 is movably installed on the lower end of the rotating vertical rod 16, and the bottom rotating shaft 20 is movably installed on the lower end of the telescopic vertical rod 19. The telescopic vertical rod 19 can rotate around the bottom rotating shaft 20. The guide plate 21 is located on the inner side of the bottom rotating shaft 20, and the guide groove 22 is opened at the front and rear ends of the guide plate 21. The clamping plate 23 is integrally formed on one side of the lower end of the guide plate 21, and the clamping screw 24 is threadedly installed on the lower end of the clamping plate 23.

[0035] In this embodiment, the telescopic upright 19 is inserted into the interior of the rotating upright 16, and the telescopic upright 19 and the rotating upright 16 are in a telescopic connection state. The bottom rotating shaft 20 is inserted into the guide rail groove 22 and slides around it. The guide rail plate 21 and the clamping plate 23 are respectively attached to the upper and lower ends of the positioning mounting plate 12. The end of the clamping screw 24 passes upward through the clamping plate 23 and presses against the lower end of the positioning mounting plate 12. After the clamping screw 24 presses against the lower end of the positioning mounting plate 12, the clamping plate 23 is locked and fixed.

[0036] In this embodiment, the rotating vertical rod 16 rotates around the top rotating shaft 15, and the rotating vertical rod 16 is set at an angle. The rotating vertical rods 16 under the main support rods 1 on both sides are arranged symmetrically around the center of the pressure cross plate 26. The rotating vertical rods 16 on both sides constitute a supporting and mounting structure for the middle pressure cross plate 26.

[0037] In this embodiment, both ends of the pressure cross plate 26 are movably mounted between two cross plate mounting shafts 25 below the main support rods 1 on both sides, and multiple pressure cross plates 26 are arranged in a line front to back. The pressure cross plates 26 are movably connected to the cross plate mounting shafts 25 so that the pressure cross plates 26 remain parallel when the rotating vertical rod 16 rotates left and right.

[0038] In this embodiment, the pressurization structure 27 includes a lifting screw 28, a rotating handle 29, a jack mounting plate 30, a lifting positioning rod 31, a pressurization jack 32 and a pressurization bonding plate 33. The lifting screw 28 is threadedly installed at the center of the pressurization cross plate 26, the rotating handle 29 is fixedly installed at the upper end of the lifting screw 28, the jack mounting plate 30 is movably installed at the lower end of the lifting screw 28, the lifting positioning rod 31 is fixedly installed on both sides of the jack mounting plate 30, the pressurization jack 32 is fixedly installed at the lower end of the jack mounting plate 30, and the pressurization bonding plate 33 is fixedly installed at the lower end of the pressurization jack 32. The lifting screw 28 is screwed in and out up and down by means of a threaded connection.

[0039] In this embodiment, the lifting and positioning rod 31 moves upward and penetrates the pressure cross plate 26, and the pressure jack 32 is located below the pressure cross plate 26. The lifting and positioning rod 31 has the effect of lifting and positioning the jack mounting plate 30, so that the lifting screw 28 drives the jack mounting plate 30 to lift and lower vertically.

[0040] It should be noted that the present invention is a bridge static load test simulation pressurization test equipment. When in use, the main support rod 1 plays a supporting and fixing effect and is located on both sides of the test bridge, so that the pressurized bonding plate 33 is bonded above the test bridge. When the pressurized jack 32 is running, the pressurized jack 32 applies pressure to the pressurized bonding plate 33, so that the pressurized bonding plate 33 is pressed toward the bridge deck, and the changes in the bridge deck are recorded to perform a static load simulation test of the bridge.

[0041] When the pressure angle needs to be adjusted, the hydraulic support rod 4 is driven to move up and down through the operation of the hydraulic cylinder 3. When the front and rear hydraulic support rods 4 are lifted and lowered at the same time, the cross beam plate 9 can be driven to move up and down for height adjustment, and the pressurized jack 32 in the middle of the equipment is preliminarily adjusted in height. When a single hydraulic support rod 4 is lifted and lowered, the heights of the front and rear rotating mounting seats 5 are different and drive the rotating mounting rod 6 to rotate to adjust the angle of the cross beam plate 9. At the same time, the rotating mounting rod 6 is telescopically movable in the telescopic sleeve rod 7 to offset the length difference of the angle change. The front and rear angles of the center pressurized cross plate 26 are adjusted by adjusting the angle of the cross beam plate 9, thereby adjusting the pressure angles of the pressurized jack 32 and the pressurized laminating plate 33.

[0042] When the left and right positions of the pressure need to be adjusted, the rotating upright rod 16 is pulled left and right to rotate around the top rotating shaft 15, and then the rotating upright rod 16 pulls the pressure horizontal plate 26 to move left and right through the horizontal plate mounting block 17 and the horizontal plate mounting shaft 25, and at the same time, the telescopic upright rod 19 telescopes at the lower end of the rotating upright rod 16, and the bottom rotating shaft 20 at the lower end of the telescopic upright rod 19 slides left and right around the guide groove 22 of the guide plate 21 to move and position with the rotating upright rod 16, thereby changing the left and right positions of the pressure horizontal plate 26, and adjusting the left and right pressure positions of the pressure jack 32 and the pressure laminating plate 33;

[0043] When the front and rear positions of the pressure application need to be adjusted, the top mounting plate 14 is inserted into the mounting slot 13 from the front and rear ends of the cross beam plate 9, and the guide plate 21 and the clamping plate 23 are fitted on the upper and lower ends of the positioning mounting plate 12 and are locked and installed by the clamping screws 24. Therefore, the front and rear positions of the center pressure cross plate 26 can be adjusted by sliding the top mounting plate 14 around the mounting slot 13 and the guide plate 21 and the clamping plate 23 around the positioning mounting plate 12, thereby adjusting the front and rear pressure application positions of the pressure jack 32 and the pressure laminating plate 33;

[0044] When the bridge size of the experiment is different, the top mounting plate 14 is used to quickly install and remove from the mounting slot 13 through the insertion structure, and the guide plate 21 and the clamping plate 23 are also quickly installed and removed from the outside of the positioning mounting plate 12 through the clamping structure, so as to quickly install and remove the center pressure plate 26 of the equipment and the pressure jack 32 below, which not only facilitates the rapid construction and use of the equipment, but also can increase or decrease the number of pressure plates 26 and pressure jacks 32 according to the size of the bridge, so as to realize modular static load pressure test;

[0045] When the pressure height needs to be adjusted, the rotating handle 29 is turned, and the rotating handle 29 drives the lifting screw 28 to rotate. The lifting screw 28 is screwed in and out up and down through the threaded connection with the pressure cross plate 26, so that the lifting screw 28 drives the jack mounting plate 30 and the pressure jack 32 below to rise and fall, and at the same time, the lifting positioning rod 31 is lifted and lowered for positioning, thereby adjusting the pressure height of the pressure jack 32 and the pressure bonding plate 33.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
