Description

Technical Field

[0001] This utility model relates to the field of bearing capacity testing technology, and in particular to a pot bearing bearing capacity testing device. Background Technology

[0002] Pot bearings are critical force-transmitting components in large-scale engineering structures such as bridges. Their load-bearing capacity directly affects the safety and stability of the structure. To ensure that pot bearings can work reliably in actual engineering projects, their performance must be tested through rigorous load-bearing capacity tests. Therefore, load-bearing capacity testing equipment is needed to test and measure various mechanical performance indicators, such as vertical load-bearing capacity, horizontal load-bearing capacity, and rotational performance, so as to provide a scientific basis for the quality assessment and engineering application of pot bearings.

[0003] Most existing testing devices place the pot bearing directly, making it difficult to precisely adjust its position. Furthermore, the pot bearing cannot be accurately placed directly below the pressure point, resulting in uneven stress distribution and affecting the accuracy of the test results. Moreover, during load-bearing tests, the device is prone to shaking, tilting, or even collapse, which can damage the testing equipment and endanger the safety of the testing personnel.

[0004] Therefore, in view of the fact that most of the above-mentioned test devices directly place the pot bearing, making it difficult to accurately adjust the position of the pot bearing, and that the pot bearing cannot be accurately placed directly below the pressure point, resulting in uneven force distribution and affecting the accuracy of the test results, a pot bearing load capacity test device can be designed. Utility Model Content

[0005] To overcome the problems that most test devices place the pot bearing directly, making it difficult to accurately adjust the position of the pot bearing, and that the pot bearing cannot be accurately placed directly below the pressure point, resulting in uneven stress and affecting the accuracy of the test results, a pot bearing bearing capacity test device is proposed.

[0006] The technical solution of this utility model is as follows: a pot bearing capacity testing device, including a base and heat dissipation holes; a placement component for placing the bearing is installed at the top of the base, and a hoisting component for limiting the bridge is provided on both sides of the placement component. Heat dissipation holes are provided on both the left and right sides of the base. The placement component includes a base plate, which is located above the base. A groove is provided on the inner surface of the base plate, and a slider is slidably connected inside the groove. A slider rod is fixedly connected to the top of the slider.

[0007] Preferably, a placement plate is fixedly connected to the top of the slide bar, a rubber pad is installed in the middle of the top of the placement plate, mounting rods are provided at the four corners of the top of the placement plate, support rods are provided at the four corners between the base plate and the base, and dampers are provided on the outside of the support rods.

[0008] Preferably, guide rods are provided at the four corners of the top of the base plate, and a top plate is slidably connected to the outer side of the guide rods. A pressure seat is provided at the middle position of the bottom of the top plate.

[0009] Preferably, a pressing cylinder is provided at the middle position of the top of the top plate, and the telescopic end of the pressing cylinder is connected to the pressure seat, and a controller is installed at the top of the guide rod.

[0010] Preferably, the hoisting assembly includes side plates, which are disposed on the left and right sides of the top plate. A telescopic cylinder is installed at the top of the top plate, and the telescopic end of the telescopic cylinder is connected to a vertical plate.

[0011] Preferably, a slide rail is provided on the surface of the upright plate facing away from the bottom plate, and a slide plate with a self-locking structure is slidably connected inside the slide rail. A mounting plate is installed on the side of the slide plate near the bottom plate, and a protective pad is provided on the top of the mounting plate.

[0012] Preferably, support seats are installed on the left and right sides of the bottom of the base, a support plate is installed on the opposite side of the support seat, and a support column is provided between the support plate and the base.

[0013] The beneficial effects of this utility model are as follows: The slider slides within the groove, causing the sliding rod and placement plate connected to the slider to move, thereby adjusting the horizontal position of the placement plate. This allows the pot support to accurately withstand pressure during the test, reducing test errors caused by positional deviations and improving the accuracy and reliability of the test results. Simultaneously, it ensures that the placement plate and pot support will not shake or tilt during the test, guaranteeing the safety and stability of the test. Furthermore, the connection method between the sliding rod, the slider, and the placement plate effectively transmits force, ensuring that the placement plate can stably transfer force to the pot support when under pressure, avoiding any impact on test results due to unstable connections.

Detailed Implementation

[0020] Please see Figures 1-5 This utility model provides an embodiment of a pot bearing capacity testing device, which includes a base 1 and heat dissipation holes 2; a placement component for placing the bearing is installed at the top of the base 1, and a hoisting component for limiting the bridge is provided on both sides of the placement component. Heat dissipation holes 2 are provided on both the left and right sides of the base 1. The placement component includes a base plate 301, which is located above the base 1. A groove 302 is provided on the inner surface of the base plate 301, and a slider 303 is slidably connected inside the groove 302. A sliding rod 304 is fixedly connected to the top of the slider 303.

[0021] Please see Figures 2-3 In this embodiment, a placement plate 305 is fixedly connected to the top of the slide rod 304. A rubber pad 306 is installed at the middle position of the top of the placement plate 305. Installation rods 307 are provided at the four corners of the top of the placement plate 305. Support rods 308 are provided at the four corners between the base plate 301 and the base 1. A damper 309 is provided on the outside of the support rods 308. Guide rods 310 are provided at the four corners of the top of the base plate 301. A top plate 311 is slidably connected to the outside of the guide rods 310. A pressure seat 312 is provided at the middle position of the bottom end of the top plate 311. A pressing cylinder 313 is provided at the middle position of the top of the top of the top plate 311. The telescopic end of the pressing cylinder 313 is connected to the pressure seat 312. A controller 314 is installed at the top of the guide rod 310.

[0022] The rubber pad 306 on the placement plate 305 effectively isolates the support from direct contact with the placement plate 305, preventing damage to the support surface due to friction and collision during placement and testing, ensuring the integrity and performance of the support are not affected. The cooperation between the sliding rod 304, the slider 303, and the sliding groove 302, as well as the guiding effect of the guide rod 310 on the top plate 311, allows the pressure to be applied smoothly and evenly to the pot support. At the same time, the damper 309 reduces vibration interference and ensures the stability of the pressure application process, thereby improving the accuracy and reliability of the test data. The support rod 308 and the damper 309 between the base plate 301 and the base 1, as well as the support and guidance of the guide rod 310 on the top plate 311, constitute a stable structural system that can withstand greater pressure during testing, ensuring the overall stability of the device, avoiding safety accidents caused by structural instability, and ensuring the safety of test personnel and equipment.

[0023] Please see Figures 4-5 In this embodiment, the hoisting assembly includes a side plate 401, which is disposed on the left and right sides of the top plate 311. A telescopic cylinder 402 is installed at the top of the top plate 311, and the telescopic end of the telescopic cylinder 402 is connected to a vertical plate 403. A slide rail 404 is provided on the surface of the vertical plate 403 facing away from the bottom. A sliding plate 405 with a self-locking structure is slidably connected inside the slide rail 404. An installation plate 406 is installed on the side of the sliding plate 405 near the bottom plate 301, and a protective pad 407 is provided at the top of the installation plate 406. Support seats 408 are installed on the left and right sides of the bottom of the base 1. A support plate 409 is installed on the opposite side of the support seat 408, and a support column 410 is provided between the support plate 409 and the base 1.

[0024] The horizontal movement of the vertical plate 403 is driven by the telescopic cylinder 402, while the sliding plate 405 can slide up and down within the slide rail 404. This allows it to adapt to bridges of different sizes and specifications. Whether it's a small bridge component or a large bridge structure, precise positioning can be achieved through adjustment, greatly improving the versatility and applicability of the testing device. The self-locking structure of the sliding plate 405 ensures that the mounting plate 406 and protective pad 407 are tightly fitted and fixed to the bridge. During the test, this effectively limits the bridge's displacement, preventing it from swaying or shifting under pressure, ensuring the safety of test personnel and equipment, and also guaranteeing the accuracy of the test data. For reliability, the protective pad 407 at the top of the mounting plate 406 is made of elastic material, which can play a good buffering role during the limiting and testing of the bridge, avoiding rigid contact between the bridge and the hoisting components, reducing wear and damage to the bridge surface, and protecting the integrity of the bridge structure. The support seat 408, support plate 409 and support column 410 at the bottom of the base 1 cooperate with each other to provide a stable support structure for the hoisting components, enhancing the stability and load-bearing capacity of the entire hoisting components, making them less prone to deformation or damage during frequent test operations, ensuring the long-term reliable operation of the hoisting components, and reducing equipment maintenance costs.

[0025] During operation, the pot bearing is placed on the placement plate 305 of the mounting assembly. The rubber pad 306 at the top of the placement plate 305 protects the bearing surface and prevents damage during placement. The telescopic cylinder 402 is activated, and its telescopic end moves the upright plate 403 to a suitable position. The sliding plate 405 is then slid to bring the protective pad 407 at the top of the mounting plate 406 into contact with both sides of the bridge. The self-locking structure of the sliding plate 405 is used to fix the position, completing the bridge's limiting function and ensuring that the bridge will not shift during the test. The pressing cylinder 313 is then activated, and its telescopic end pushes the pressure seat 312 downward. The pressure seat 312 transmits pressure to the top plate 311, which moves along the guide rod 310. The pressure is applied to the pot support on the placement plate 305 by sliding downwards. During the pressure transmission process, the support rods 308 at the four corners between the base plate 301 and the base 1 and the dampers 309 on the outside can play a buffering and stabilizing role, preventing excessive vibration during the pressure transmission process from affecting the test results. As the pressing cylinder 313 continuously applies pressure, the controller 314 monitors the pressure value and displacement change of the pot support in real time. At the same time, the slider 303 slides in the groove 302, and the slide rod 304 drives the placement plate 305 to move accordingly to adapt to the pressure change, ensuring that the pot support can deform and bear load smoothly during the stress process. When the predetermined test pressure is reached or the pot support shows signs of damage, the operation of the pressing cylinder 313 is stopped.
