[0002] A rubber bearing is a road bridge bearing composed of steel components and rubber. The rubber bearing is used to connect the box girder and the pier and plays a crucial role in the bridge. After the rubber bearing is produced by the manufacturer, it is necessary to conduct a compression-shear test on the rubber bearing to test the maximum pressure and maximum shear force that the rubber bearing can withstand. During the test process, some debris will remain on the compression-shear testing machine. If these debris are not cleaned in time, it may affect the accuracy and performance of the next detection of the compression-shear testing machine. Therefore, it is necessary to regularly clean the debris remaining on the compression-shear testing machine.

Detailed Embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] During specific implementation: As Figures 1-4 shown, a shear compression testing machine for rubber bearings used in road bridges that is convenient for cleaning includes: a working frame 1, a hydraulic cylinder 2 fixedly connected to the inner wall of the working frame 1, a pressing block 3 fixedly connected to the bottom end of the hydraulic cylinder 2, a placement cart 4 slidably connected to the top of the working frame 1, and a cleaning mechanism 5 arranged on the surface of the placement cart 4; among them, the cleaning mechanism 5 includes a cleaning plate 51 slidably connected to the inner wall of the placement cart 4, a lead screw 53 rotatably connected to one side of the inner wall of the placement cart 4, the inner wall of the cleaning plate 51 is threadedly connected to the surface of the lead screw 53, a servo motor 54 is fixedly connected to the front end of the placement cart 4, the output shaft of the servo motor 54 is fixedly connected to one end of the lead screw 53, a baffle 52 is arranged on the inner wall of the placement cart 4, a collection box 55 is arranged at the rear end of the working frame 1, a cleaning assembly 56 is arranged on the surface of the placement cart 4, and the cleaning plate 51 is made of stainless steel.

[0026] It should be noted that in the above description, the hydraulic cylinder 2, the placement cart 4, the servo motor 54, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply for the hydraulic cylinder 2, the placement cart 4, and the servo motor 54 can be powered by an internal power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0027] When it is necessary to test and detect the rubber bearing, the rubber bearing is placed in the placement cart 4. Manually open the placement cart 4, and the placement cart 4 moves on the working frame 1 to directly below the pressing block 3. Manually close the placement cart 4, and manually open the hydraulic cylinder 2. The bottom end of the hydraulic cylinder 2 moves downward to drive the pressing block 3 to move downward, so that the pressing block 3 tests and detects the rubber bearing on the placement cart 4. After the detection is completed, the hydraulic cylinder 2 drives the pressing block 3 to move upward to an appropriate position, and then manually close the hydraulic cylinder 2.

[0028] When it is necessary to clean the rubber bearing debris on the shear compression testing machine, manually open the placement cart 4, and the placement cart 4 moves onto the collection box 55. Manually close the placement cart 4 and turn on the servo motor 54. The output shaft of the servo motor 54 rotates to drive the lead screw 53 to rotate. The rotation of the lead screw 53 drives the cleaning plate 51 to move. The movement of the cleaning plate 51 scrapes the rubber bearing debris in the placement cart 4 into the collection box 55. At this time, the servo motor 54 drives the lead screw 53 to rotate in the reverse direction, and the rotation of the lead screw 53 drives the cleaning plate 51 to move to the inner wall of the placement cart 4, and then manually turn off the servo motor 54.

[0029] As Figure 2 shown, the cleaning assembly 56 includes a scraper 561 slidably connected to the inner wall of the placement cart 4, a spring 562 fixedly connected to the bottom of the scraper 561, and the bottom end of the spring 562 is fixedly connected to the inner wall of the placement cart 4. The scraper 561 is made of rubber.

[0030] The pressing block 3 moves up to a proper position, and the elastic force of the spring 562 pushes the scraping plate 561 up, causing the scraping plate 561 to abut against the bottom of the pressing block 3. At this time, the placing cart 4 moves and drives the scraping plate 561 to move. The moving scraping plate 561 scrapes the rubber support debris adhering to the bottom of the pressing block 3, causing the debris to fall onto the placing cart 4.

[0031] As Figure 3 shown, a blocking plate 566 is fixedly connected to the rear end of the cleaning plate 51. The surface of the blocking plate 566 is slidably connected to the inner wall of the placing cart 4, and one side of the blocking plate 566 is fixedly connected to one side of the baffle plate 52.

[0032] The movement of the cleaning plate 51 drives the movement of the blocking plate 566, and the movement of the blocking plate 566 drives the movement of the baffle plate 52, making the rear end of the placing cart 4 in an unobstructed state, thereby scraping out the debris in the placing cart 4.

[0033] As Figure 4 shown, a cleaning frame 563 is slidably connected to the inner wall of the cleaning plate 51. The inner side of the cleaning frame 563 matches the upper surface of the scraping plate 561. The cleaning frame 563 is made of stainless steel. One side of the cleaning frame 563 is fixedly connected with a limiting block 564, and the surface of the limiting block 564 is slidably connected to the inner wall of the scraping plate 561.

[0034] The movement of the cleaning plate 51 drives the movement of the cleaning frame 563, and the movement of the cleaning frame 563 scrapes the debris adhering to the scraping plate 561, causing the debris to separate from the scraping plate 561.

[0035] As Figure 2 shown, a positioning frame 565 is fixedly connected to the top of the collection box 55. When the placing cart 4 moves and abuts against the positioning frame 565, the placing cart 4 is manually closed, enabling the placing cart 4 to accurately move above the collection box 55.

[0036] When the present utility model is in use, the pressing block 3 moves up to a proper position, and the elastic force of the spring 562 pushes the scraping plate 561 and the cleaning frame 563 up, causing the scraping plate 561 to abut against the bottom of the pressing block 3. At this time, the placing cart 4 is manually opened, and the placing cart 4 moves and drives the scraping plate 561 to move. The moving scraping plate 561 scrapes the rubber support debris adhering to the bottom of the pressing block 3, causing the debris to fall onto the placing cart 4. The placing cart 4 moves and abuts against the positioning frame 565, and the placing cart 4 is manually closed and the servo motor 54 is turned on. The output shaft of the servo motor 54 rotates and drives the cleaning plate 51, the blocking plate 566, and the baffle plate 52 to move through the moving lead screw 53. The cleaning plate 51 moves to scrape the rubber support debris in the placing cart 4 into the collection box 55. At this time, the servo motor 54 drives the lead screw 53 to rotate in the reverse direction, and the rotation of the lead screw 53 drives the cleaning plate 51 to move to the inner wall of the placing cart 4, and the servo motor 54 is manually turned off.

[0037] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
