Description

Technical Field

[0001] This utility model relates to the field of dam simulation testing, and in particular to a dam strength simulation testing device. Background Technology

[0002] Currently, in the process of water conservancy project construction, in order to ensure quality and safety, it is usually necessary to test the strength of the dam, including the strength test of the dam's concrete structure. The strength test method is to cut a small piece of each batch of concrete and then test its strength by squeezing it through a pressure testing machine.

[0003] A search revealed a Chinese patent publication number CN221745737U, which discloses a hydraulic dam strength simulation testing device. This patent includes a support rod and a limiting component inside the support rod, with a fixing ring at the top and a moving rod slidably connected to the inner wall of the support rod. The limiting component includes a moving rod with its outer side slidably connected to the inner wall of the support rod. A connecting rod is fixedly connected to one side of the moving rod, and a rotating screw is rotatably connected to one end of the connecting rod. This device limits the fall of the testing body by the limiting component, provides convenient support and fixation by the support component, and allows for easy locking and fixing of the strength testing body by the snap-fit ​​block. The height of the strength testing body can be easily adjusted by the second motor and the second rotating rod, and a baffle prevents fragments from flying when the strength testing body lands. However, compared to existing technologies, after the strength test block is crushed, the testing platform needs to be manually cleaned before the concrete test block is placed into the device for testing. The cleaning and replacement process is cumbersome and inconvenient, and its practicality needs improvement. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figure 1 — Figure 6As shown, a dam strength simulation testing device includes a bottom shell 101 and a top shell 104. A testing mechanism is mounted on the top shell 104, including a hydraulic cylinder 301. A hydraulic cylinder connecting frame 302 is bolted to the hydraulic cylinder 301 and bolted to the top of the top shell 104. A testing head 303 is bolted to the output end of the hydraulic cylinder 301 and connected to an external controller via wireless transmission. Three annularly arranged columns 102 are bolted between the bottom shell 101 and the top shell 104. A protective plate 105 is bolted to the top of the bottom shell 101 and bolted to the inner sides of two adjacent columns 102. A rotating mechanism is mounted on the top of the bottom shell 101, including a rotating shaft 201 rotatably connected to the top of the bottom shell 101. Three partitions 202 are bolted to the side of shaft 201. The partitions 202 divide the cylindrical area formed by the bottom shell 101 and the top shell 104 into three parts. The staff can automatically and continuously perform the three steps of placing the dam concrete test block, testing and cleaning the concrete fragments, which greatly facilitates the testing work. The bottom of the partition 202 is bolted to the bottom plate 203. The top of the bottom plate 203 is bolted to several elastic telescopic rods 204. The top of the elastic telescopic rods 204 is bolted to the top of the support platform 205. When the dam concrete test block is placed on the support platform 205 for strength simulation testing, the hydraulic cylinder 301 presses down the testing head 303. The testing head 303 presses down on the concrete test block. The concrete test block is pressed down, which compresses the elastic telescopic rods 204 until the concrete test block is crushed. The testing head 303 transmits the pressure data to the external controller.

[0027] A cleaning mechanism is bolted to one side of the top shell 104. The cleaning mechanism includes a mounting box 401, which contains a transmission mechanism. A rotating column 402 is rotatably connected inside the mounting box 401. Several scrapers 403 are bolted to the side of the rotating column 402. During each rotation of the partition plate 202, the transmission mechanism drives the scrapers 403 to rotate. The rotation direction of the scrapers 403 is opposite to the rotation direction of the support platform 205, which better cleans the top of the fixed plate 206 and prevents the concrete test block from being affected by fragments and debris during testing.

[0028] In this embodiment, a locking ball 207 is bolted to the side of the partition 202 away from the rotating shaft 201. A positioning groove 103 that cooperates with the locking ball 207 is provided on the inner side of the column 102. The positioning groove 103 and the locking ball 207 are designed so that the detection head 303 can be aligned with the support platform 205 each time the operator rotates the rotating shaft 201 and the partition 202, thereby improving the detection efficiency.

[0029] In this embodiment, several elastic telescopic rods 204 are arranged in a ring, and each elastic telescopic rod 204 is respectively set inside two adjacent partitions 202. This arrangement is beneficial for workers to continuously produce multiple batches of concrete test blocks.

[0030] In this embodiment, a fixing plate 206 is welded to the inner side of the partition 202. The fixing plate 206 has a through hole for the detection head 303 to pass through. The fixing plate 206 can fix the concrete test block. When the worker places the concrete test block on the support platform 205, the concrete test block is pressed down by the elastic telescopic rod 204 through the support platform 205. The elastic force is used to fix the concrete test block between the support platform 205 and the fixing plate 206, preventing the concrete test block from falling off the top of the support platform 205 when the partition 202 rotates.

[0031] In this embodiment, the side of the support platform 205 is provided with a chamfer, the bottom side of the scraper 403 is at the same height as the top of the support platform 205, and a cleaning strip 404 is attached to the scraper 403. The cleaning strip 404 has a certain elasticity. The setting of the cleaning strip 404 is conducive to cleaning the top and the inclined part of the support platform 205 more thoroughly.

[0032] In this embodiment, the transmission mechanism includes a first gear 501, which is bolted to the top of the partition 202. The first gear 501 has a hole for the detection head 303 to pass through. A second gear 502 meshes with one side of the first gear 501. The second gear 502 is rotatably connected to the mounting box 401. A first bevel gear 503 is bolted to the bottom of the second gear 502. A second bevel gear 504 meshes with one side of the first bevel gear 503. The second bevel gear 504 is rotatably connected to the mounting box 401. A third bevel gear 505 meshes with one side of the second bevel gear 504. The bottom of the third bevel gear 505 is bolted to the top of the rotating column 402. By setting the first bevel gear 503, the second bevel gear 504, and the third bevel gear 505, the rotational movement of the partition 202 is redirected, so that the rotational column 402 and the scraper 403 are opposite to the rotational direction of the support platform 205, thus better performing the cleaning work on the top of the support platform 205.

[0033] Working principle: When using this device, the testing personnel place the dam concrete test block on the support platform 205, away from the installation box 401 and the hydraulic cylinder 301. The concrete test block is pressed down by the elastic telescopic rod 204 through the support platform 205, using the elastic force to fix the concrete test block between the support platform 205 and the fixing plate 206, preventing the concrete test block from falling off the top of the support platform 205 when the partition plate 202 rotates. Then, the partition plate 202 is pushed to rotate the concrete test block on the support platform 205 toward the hydraulic cylinder 301 until the locking ball 207 is locked back into the positioning groove 103. The hydraulic cylinder 301 is then activated, and the hydraulic cylinder 301 presses down on the testing head 303, which passes through the fixing plate 206 and abuts against the top of the concrete test block. Continuing to press down, the elastic telescopic rod 204 is further compressed until the concrete test block is crushed. The protective plate 105 prevents the fragments from flying outside the device. The detection head 303 transmits and records the pressure data. Next, the staff places the next batch of test blocks onto the support platform 205 in the same position. The partition 202 is rotated again, and the crushed fragments move with the support platform 205 to the scraper 403. During rotation, the partition 202 drives the first gear 501 to rotate, which in turn drives the second gear 502. The second gear 502, through the meshing of the first bevel gear 503, the second bevel gear 504, and the third bevel gear 505, drives the rotating column 402 to rotate. The rotation direction of the rotating column 402 is opposite to that of the first gear 501, thus driving the scraper 403 to rotate. This cleans the top of the support platform 205, preparing it for the next concrete test block placement between the support platform 205 and the fixing plate 206. This facilitates the staff's testing work and is convenient and safe to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
