When these floor slab samples are tested for load-bearing capacity, only the pressure on the floor slab sample is measured. The bending test of the floor slab requires the installation of corresponding equipment for testing, and cannot be performed simultaneously. In addition, if the sample is damaged during the testing process, the existing testing equipment may be damaged as well. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-9 As shown, a testing device for the bearing capacity of a building structure includes a frame 4, a conveying mechanism 3 on the inner side of the frame 4, a hydraulic oil station 5 fixed on the front side of the frame 4, a pressurizing mechanism 1 and a testing mechanism 2, the pressurizing mechanism 1 being located on the upper side of the frame 4 and the testing mechanism 2 being located below the pressurizing mechanism 1.

[0030] In this embodiment: the pressurizing mechanism 1 includes a first hydraulic cylinder 11, the telescopic part of the first hydraulic cylinder 11 is rotatably connected to a pressurizing frame 12, and a plurality of pressurizing sliders 13 are slidably connected to the lower side of the pressurizing frame 12. The telescopic part of the first hydraulic cylinder 11 pushes the pressurizing frame 12 to move downward, and the downward movement of the pressurizing frame 12 pushes the plurality of pressurizing sliders 13 to press on the top of the sample to be tested. In addition, the detection position can be adjusted by rotating the pressurizing frame 12 and sliding the plurality of pressurizing sliders 13.

[0031] In this embodiment: the detection mechanism 2 includes a support frame 24, a guide rail 21 is fixed at the middle position of the inner side of the support frame 24, a sliding seat 22 is slidably connected to the upper side of the guide rail 21, a dial gauge 23 is fixed inside the sliding seat 22, protective inclined plates 6 are fixed on both sides of the support frame 24, and support horizontal plates 26 are provided on the front and rear sides of the top of the support frame 24. Pressure sensors 25 are fixed between the two support horizontal plates 26 and the support frame 24. The support frame 24 is fixed at the middle position of the inner side of the frame 4. The detection end of the dial gauge 23 passes through the two protective inclined plates 6 and is close to each other. The sliding seat 22 on the guide rail 21 drives the dial gauge 23 to move back and forth, so that the detection end of the dial gauge 23 is pressed against the bottom of the sample to be tested. At the same time, the support horizontal plates 26 on the support frame 24 support the sample to be tested. In addition, the pressure sensor 25 between the support horizontal plate 26 and the support frame 24 is used to detect the bearing pressure of the sample.

[0032] In this embodiment, the conveying mechanism 3 includes two second hydraulic cylinders 31. Each second hydraulic cylinder 31 has a pusher plate 32 fixed to its telescopic part. The fixed parts of the two second hydraulic cylinders 31 are fixed to both sides of the support frame 24. The pusher plate 32 is slidably connected to the inner side of the frame 4. The front and rear ends of the two pusher plates 32 are provided with feeding components, and the two feeding components are located on the front and rear sides of the support frame 24 respectively. Each pusher plate 32 has a connecting plate 37 hinged to its front and rear ends. The two pusher plates 32 are moved towards the support frame 24 by the simultaneous retraction of the telescopic parts of the two second hydraulic cylinders 31. The feeding components are pushed upward by the connecting plate 37, thereby conveying the sample to be tested.

[0033] In this embodiment: the feeding assembly includes a conveyor frame 33, with multiple conveyor rollers 35 rotatably connected to the inner side of the conveyor frame 33, and a conveyor belt 34 sleeved on the outer side of the multiple conveyor rollers 35. A conveyor motor 36 for driving the conveyor rollers 35 to rotate is fixedly installed at one end of the conveyor frame 33. The upper end of the connecting plate 37 is hinged to the bottom of the conveyor frame 33. The conveyor motor 36 drives the conveyor rollers 35 of its rotating part to rotate, and the rotation of the conveyor rollers 35 drives the conveyor belt 34 to transport the sample to be tested.

[0034] Working principle: During use, the telescopic parts of the two second hydraulic cylinders 31 retract simultaneously, driving the two pusher plates 32 to move towards the support frame 24. At this time, the connecting plates 37 on the two pusher plates 32 push the two conveyor frames 33 to move upward, so that the conveyor belt 34 on the conveyor frame 33 is higher than the upper end of the support frame 24. The sample to be tested is then placed on the conveyor belt 34. The conveyor motor 36 drives the conveyor roller 35 of its rotating part to rotate. The rotation of the conveyor roller 35 drives the conveyor belt 34 to transport the sample to be tested to the bottom of the pressure frame 12.

[0035] When the sample to be tested moves to the bottom of the pressure frame 12, the extension parts of the two second hydraulic cylinders 31 extend to push their respective push plates 32 away from each other, and the two conveyor frames 33 move downward through the connecting plate 37, so as to place the sample to be tested at the top position of the support frame 24.

[0036] Subsequently, the extension and retraction part of the first hydraulic cylinder 11 pushes the pressure frame 12 to move downward. The downward movement of the pressure frame 12 pushes multiple pressure sliders 13 to press against the top of the sample to be tested. In addition, the detection position can be adjusted by rotating the pressure frame 12 and sliding the multiple pressure sliders 13 on the pressure frame 12. At this time, the sliding seat 22 on the guide rail 21 drives the dial indicator 23 to move back and forth, so that the detection end of the dial indicator 23 is pressed against the bottom of the sample to be tested, thereby detecting the bending state of the sample during the sample test. At the same time, the support plate 26 on the support frame 24 supports the sample to be tested. In addition, the pressure sensor 25 between the support plate 26 and the support frame 24 detects the bearing pressure of the sample.

[0037] In addition, if the sample breaks during testing, the broken sample can be sent out from both sides of the frame 4 through the two protective inclined plates 6, thereby preventing sample fragments from damaging the dial gauge 23 and pressure sensor 25, and also making it easier to clean the broken sample.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
