Description

Technical Field

[0001] This utility model relates to the technical field of static load testing equipment, specifically to a static load testing equipment for ultra-large tonnage loads. Background Technology

[0002] The main challenges of ultra-large tonnage static load tests include the extremely large test tonnage, poor foundation bearing capacity, and high safety risks. The extremely large test tonnage places higher demands on the rigidity of the steel beams used in the test, the stable hoisting of the counterweights, and the simultaneous operation of multiple loads in parallel. Poor foundation bearing capacity and the potential presence of backfill soil around the piles further increase the difficulty of the test. High safety risks are also present; for example, the loading platform is as high as 13 meters, posing significant safety hazards during the transportation of precast blocks and the stability of the loading platform.

[0003] A search revealed an ultra-large tonnage static load testing device disclosed in application document CN217537100U. This device uses a load-bearing plate to support an upper concrete block. A level is used to check the levelness of the load-bearing plate; tilting the plate would cause the upper concrete block to collapse, posing a significant danger. After inspection, the plate is leveled and fixed to the upper surface of the support plate. A baffle is inserted into a rectangular groove inside the load-bearing plate and secured with bolts. The baffle prevents the inner concrete block from moving and collapsing, increasing safety. By stacking concrete blocks, the tonnage of the test can be increased. Anti-tilting columns support the four corners of the load-bearing plate to prevent tilting and ensure the stability of the concrete block, improving safety. A load-bearing beam supports the middle of the load-bearing plate to prevent deformation, and a balance seat supports both ends of the load-bearing beam to prevent bending, increasing structural stability and improving safety.

[0004] However, certain defects and shortcomings still exist and need to be optimized. The specific defects and shortcomings are as follows: The height of the baffle inserted into the top surface of the load-bearing plate in this ultra-large tonnage static load test device is fixed and cannot be adjusted. This results in limitations in the protection height for high-stalled concrete blocks, and the protection height for low-stalled concrete blocks can easily hinder the transportation process of the concrete blocks. Therefore, it is necessary to design a static load test device for ultra-large tonnage to solve the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to provide a static load testing device for ultra-large tonnage concrete blocks. This device optimizes the concrete block baffle structure based on existing ultra-large tonnage static load testing devices, making the overall device able to protect the concrete blocks at adjustable heights. This provides protection for concrete blocks of different stacking heights, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A static load testing device for ultra-large tonnage loads includes a main body for such testing. The main body is composed of a support mechanism and a weighting mechanism. The weighting mechanism includes a lower load-bearing platform located on the top surface of the support mechanism. An upper load-bearing platform is arranged parallel to the top of the lower load-bearing platform. Concrete block protective plate assemblies are installed through the upper load-bearing platform near its perimeter. Several sets of adjustable protective height assemblies are arranged near the perimeter between the upper and lower load-bearing platforms. Each set of adjustable protective height assemblies includes a bottom rod, multiple sets of heightening rods, a top rod, and multiple sets of locking screws. An assembly insert is fixedly installed at the bottom center of any set of heightening rods and the top rod. An assembly slot adapted to the assembly insert is opened at the top center of any set of heightening rods and the bottom rod.

[0008] As a preferred embodiment of this utility model, the bottom rod, the top rod, and the adjacent set of heightening rods, as well as the two adjacent sets of heightening rods, are all connected by assembly inserts. The length of the assembly insert is equal to the depth of the assembly groove. The ends of the bottom rod and the top rod away from the heightening rods are respectively fixedly connected to the lower load-bearing platform and the upper load-bearing platform.

[0009] As a preferred embodiment of this utility model, the outer surface of any one of the base rods and the multiple sets of heightening rods is provided with an external locking screw hole adapted to the locking screw, and the outer surface of the assembly insert is provided with an internal locking screw hole adapted to the locking screw.

[0010] As a preferred embodiment of this utility model, the concrete block protective plate assembly includes several sets of rectangularly distributed protective piles. Any two sets of rectangularly distributed protective piles are fixedly connected near the top by a connecting limiting rod. The upper load-bearing platform has pile holes corresponding to the several sets of rectangularly distributed protective piles through it near its perimeter, and the protective piles are slidably connected to the corresponding pile holes.

[0011] As a preferred embodiment of this utility model, the support mechanism includes a test pile platform, a test pile body, and a pressure application component. The test pile body is installed through the center of the test pile platform, and the pressure application component is located at the top of the test pile body.

[0012] As a preferred embodiment of this utility model, the top surface of the test pile platform is provided with a first support seat and a second support seat on both sides near the pressure application component, and the first support seat, the second support seat and the test pile platform are fixedly connected by a positioning rod.

[0013] As a preferred embodiment of this utility model, the pressure application component includes a lower pressure plate fixedly installed at the top of the test pile body, and an upper pressure plate is movably installed on the top of the lower pressure plate through multiple sets of jacks.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the number of height-adjusting rods can be increased or decreased according to the required height of the concrete blocks to be stacked, thereby adjusting the height of the adjustable protective height component. As the height of the adjustable protective height component is adjusted, the setting height of the upper load-bearing platform also rises or falls accordingly, thus adjusting the protective height of the concrete blocks on the top surface of the upper load-bearing platform. Furthermore, based on the existing ultra-large tonnage static load testing device, the concrete block baffle structure is optimized, enabling the overall equipment to protect the height of the concrete blocks with adjustable height. This effectively solves the technical problems mentioned in the background art for protecting concrete blocks of different stacking heights. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] This utility model embodiment provides a static load testing device for ultra-large tonnage. The static load testing device for ultra-large tonnage optimizes the concrete block baffle structure based on the existing ultra-large tonnage static load testing device, so that the overall device can protect the concrete block with adjustable height, thereby protecting concrete blocks with different stacking heights and solving the problems mentioned in the background art.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A static load testing device for ultra-large tonnage loads includes a main body 1 for ultra-large tonnage static load testing, which is composed of a support mechanism 2 and a weighting mechanism 3.

[0027] The support mechanism 2 includes a test pile platform 21, a test pile body 22, and a pressure application component 23. The test pile body 22 is installed through the center of the test pile platform 21, and the pressure application component 23 is located at the top of the test pile body 22. A first support seat 211 and a second support seat 212 are respectively provided on both sides of the top surface of the test pile platform 21 near the pressure application component 23, and the first support seat 211, the second support seat 212, and the test pile platform 21 are fixedly connected by a positioning rod 213. The pressure application component 23 includes a lower pressure plate 231 fixedly installed at the top of the test pile body 22. An upper pressure plate 233 is movably installed on the top of the lower pressure plate 231 via multiple sets of jacks 232. When 232 is started, the upper end of the jack 232 pushes the upper pressure plate 233, which in turn pushes the upper weighting mechanism 3. Due to the extremely large weight of the weighting mechanism 3, it will not move, but it will exert a reaction force on the upper pressure plate 233. The reaction force is transmitted sequentially to the jack and the lower pressure plate 231, and then to the test pile body 22. The reaction force is the same as the thrust of the jack 232. By adjusting the thrust of the jack 232, the pressure on the test pile body 22 is increased. The sinking displacement of the test pile over time is observed, and the static load capacity of the test pile is tested. The first support seat 211, the second support seat 212, and the positioning rod 213 can effectively provide stable support for the weighting mechanism 3.

[0028] The weight-reinforcing mechanism 3 includes a lower load-bearing platform 31 located on the top surface of the support mechanism 2. An upper load-bearing platform 32 is arranged parallel to the top of the lower load-bearing platform 31. Concrete block protective plate assemblies 33 are installed through the upper load-bearing platform 32 near its perimeter. Several sets of adjustable protection height assemblies 34 are arranged near the perimeter between the upper load-bearing platform 32 and the lower load-bearing platform 31. Each set of adjustable protection height assemblies 34 includes a bottom rod 341, multiple sets of heightening rods 342, a top rod 343, and multiple sets of locking screws 344. An assembly insert 3 is fixedly installed at the bottom center of any set of heightening rods 342 and the top rod 343. 45. Each of the multiple sets of heightening rods 342 and the center of the top surface of the bottom rod 341 is provided with an assembly groove 346 adapted to the assembly rod 345. The assembly rod 345 is inserted into the assembly groove 346 for plug-in assembly and locked in place by a locking screw 344. The number of heightening rods 342 can be increased or decreased according to the required height of the concrete blocks to be stacked, thereby adjusting the height of the adjustable protection height component 34. As the height of the adjustable protection height component 34 is adjusted, the setting height of the upper load-bearing platform 32 rises or falls accordingly, thus adjusting the protection height of the concrete blocks on the top surface of the upper load-bearing platform 32.

[0029] Furthermore, in this embodiment, please refer to Figure 2 The concrete block protection panel assembly 33 includes several sets of rectangularly distributed protective piles 331. Any two sets of rectangularly distributed protective piles 331 are fixedly connected near the top by a connecting limiting rod 332. The upper load-bearing platform 32 has pile holes corresponding to the several sets of rectangularly distributed protective piles 331 through it near its perimeter. The protective piles 331 are slidably connected to the corresponding pile holes. The design of several sets of rectangularly distributed protective piles 331 can protect the concrete block located on the top surface of the upper load-bearing platform 32, prevent the concrete block from moving and collapsing, and increase safety protection. At the same time, the design of the connecting limiting rod 332 can make the structure of the concrete block protection panel assembly 33 itself more stable, which is beneficial to the protection of the concrete block.

[0030] Furthermore, in this embodiment, please refer to Figure 3The bottom rod 341, top rod 343, and adjacent sets of heightening rods 342, as well as two adjacent sets of heightening rods 342, are all connected by assembly insert rods 345. The length of the assembly insert rod 345 is equal to the depth of the assembly groove 346. The ends of the bottom rod 341 and top rod 343 away from the heightening rods 342 are fixedly connected to the lower support plate 31 and the upper support plate 32, respectively. The outer surface of the bottom rod 341 and any set of heightening rods 342 is provided with an outer locking screw hole 347 that matches the locking screw 344. The outer surface of the assembly insert rod 345 is provided with an inner locking screw hole 348 that matches the locking screw 344. The structural design of the assembly insert rod 345, the outer locking screw hole 347, the inner locking screw hole 348, and the locking screw 344 makes it easier and faster to increase or decrease the number of heightening rods 342, while also ensuring a stable structure.

[0031] In this embodiment, the specific implementation scenario is as follows: the assembly rod 345 is embedded into the assembly slot 346 to achieve plug-in assembly, and is locked and fixed by the locking screw 344 passing through the outer locking screw hole 347 and the inner locking screw hole 348. The number of sets of height-adjustable components 342 can be increased or decreased according to the required height of the concrete blocks to be stacked, thereby adjusting the height of the protective height adjustable component 34. As the height of the protective height adjustable component 34 is adjusted, the setting height of the upper load-bearing platform 32 rises or falls accordingly, allowing the protective height of the concrete blocks on the top surface of the upper load-bearing platform 32 to be adjusted. After completion, concrete blocks required for ultra-large tonnage static load tests can be stacked on the top surface of the upper load-bearing platform 32. Simultaneously, multiple sets of... When jack 232 is started, the upper end of jack 232 pushes the upper pressure plate 233, which in turn pushes the upper weighting mechanism 3. Due to the extremely heavy weight of the weighting mechanism 3, the weighting mechanism 3 will not move, but it will exert a reaction force on the upper pressure plate 233. The reaction force is transmitted sequentially to the jack and the lower pressure plate 231, and then to the test pile body 22. The reaction force is the same as the thrust of jack 232. By adjusting the thrust of jack 232, the pressure on the test pile body 22 is increased, and the settlement displacement of the test pile over time is observed to test the static load capacity of the test pile. Moreover, compared with the existing ultra-large tonnage static load test device, the height of the concrete block can be adjusted, thus providing protection for concrete blocks with different stacking heights.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
