[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a post-cast strip structure bearing capacity testing device, including a housing 1, a support rod 2 installed on the bottom surface of the housing 1, a caster wheel 3 installed at the bottom end of the support rod 2, a handrail 4 installed on one side surface of the housing 1, a fixing plate 5 installed on one side surface of the bottom of the housing 1, an air pump 6 installed on one side surface of the fixing plate 5, an air nozzle 7 installed on one side surface of the air pump 6, a main fixing block 8 installed on one side surface of the top of the housing 1, a top cover 9 rotatably connected to the other side surface of the top of the housing 1, a secondary fixing block 10 installed on one side surface of the top cover 9, a screw 11 installed on the inner wall of the secondary fixing block 10, a handle 12 installed on the top surface of the screw 11, and an adjustment component 13 installed on the inner wall of the housing 1.
[0023] Adjustment assembly 13 includes a first limiting rail 1301 and a second limiting rail 1302 installed on the inner wall of housing 1. A first lead screw 1303 is rotatably connected to the inner wall of the first limiting rail 1301. A first motor 1304 is installed at one end of the first lead screw 1303. A first slider 1305 is installed on the outer wall of the first lead screw 1303. One end of a third limiting rail 1306 is installed on one side surface of the first slider 1305. A second slider 1307 is installed at the other end of the third limiting rail 1306. A limiting slide rod 1308 is installed on the inner wall of the slider 1307. A second lead screw 1309 is rotatably connected to the inner wall of the third limiting rail 1306. A second motor 1310 is installed at one end of the second lead screw 1309. A third slider 1311 is installed on the outer wall of the second lead screw 1309. A connecting plate 1312 is installed on the bottom surface of the third slider 1311. A hydraulic push rod 1313 is installed on the bottom surface of the connecting plate 1312. A displacement sensor 1314 is installed at one end of the hydraulic push rod 1313.
[0024] In this embodiment, as Figure 1 As shown, there are four casters 3, and the casters 3 are symmetrical about the central axis of the housing 1. With this design, the device can be quickly moved by holding the handle 4 and using the casters 3 as needed, which is convenient for detecting different positions of the post-pouring strip.
[0025] In this embodiment, as Figure 2 As shown, there are multiple air jets 7; through this design, the air pump 6 can be activated, and the dust and impurities on the surface of the displacement sensor 1314 can be blown off through the air jets 7, preventing the dust and impurities from affecting the detection results.
[0026] In this embodiment, as Figure 3 As shown, the inner wall of the main fixing block 8 has a fixing groove whose internal dimensions are consistent with the external dimensions of the screw 11, and the handle 12 and the screw 11 form a screw transmission mechanism. With this design, when the top cover 9 is closed, the auxiliary fixing block 10 fits against the main fixing block 8, and the fixing groove is located directly below the screw 11. The handle 12 can be rotated to drive the screw 11 to rotate and insert into the fixing groove, so as to quickly fix the top cover 9. Conversely, the top cover 9 can be released and opened to maintain the inside of the housing 1.
[0027] In this embodiment, as Figure 4As shown, the first motor 1304 forms a transmission mechanism with the first lead screw 1303 and the first slider 1305. With this design, the first motor 1304 can be started as needed to drive the first lead screw 1303 to rotate, thereby adjusting the position of the first slider 1305. The third limit rail 1306 moves synchronously, and the second slider 1307 slides on the outer wall of the limit rail 1308. This allows for rapid adjustment of the longitudinal position of the hydraulic push rod 1313 and the displacement sensor 1314, facilitating the detection of different positions of the post-cast strip.
[0028] In this embodiment, as Figure 4 As shown, the second motor 1310 forms a transmission mechanism with the third slider 1311 via the second lead screw 1309. With this design, the second motor 1310 can be started as needed to drive the second lead screw 1309 to rotate, thereby adjusting the position of the third slider 1311. This allows for rapid adjustment of the lateral position of the hydraulic push rod 1313 and the displacement sensor 1314, facilitating the detection of different positions of the post-cast strip.
[0029] In this embodiment, as Figure 4 As shown, the hydraulic push rod 1313 and the displacement sensor 1314 constitute a telescopic mechanism. With this design, the hydraulic push rod 1313 can be activated to extend the displacement sensor 1314. The hydraulic push rod 1313 can be used to apply load to the post-cast strip structure. The displacement sensor 1314 can be used to monitor and record information such as strain, deformation, and displacement of the structure in real time during the loading process, thereby helping to evaluate the load-bearing capacity and performance of the structure.
[0030] The method of use and advantages of this utility model: The working process of this post-cast strip structure bearing capacity testing device is as follows:
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the device can be quickly moved by holding the handle 4 and using the casters 3, as needed. Then, the first motor 1304 can be started, driving the first lead screw 1303 to rotate, which can adjust the position of the first slider 1305. Simultaneously, the third limit rail 1306 moves, and the second slider 1307 slides on the outer wall of the limit slide rod 1308. This allows for rapid adjustment of the longitudinal position of the hydraulic push rod 1313 and the displacement sensor 1314. The second motor 1310 can also be started, driving the second lead screw 1309 to rotate, which can adjust the position of the third slider 1311. The hydraulic push rod 1313 and displacement sensor 1314 can be quickly adjusted to facilitate the detection of different positions of the post-cast strip. After the hydraulic push rod 1313 and displacement sensor 1314 have detected the post-cast strip structure, the air pump 6 can be started. The air jet 7 can blow off the dust and impurities on the surface of the displacement sensor 1314 to prevent the dust and impurities from affecting the subsequent detection results. If maintenance of the internal components of the housing 1 is required, the handle 12 can be turned to pull the screw 11 out of the fixing groove of the main fixing block 8, and then the top cover 9 can be rotated open.
