Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a building load-bearing capacity testing platform. Background Technology
[0002] Currently, dynamic penetration tests are used in the construction of buildings, roads, municipal engineering, and water conservancy projects to test the bearing capacity of the foundation. Among them, the most widely used dynamic penetration test device is the heavy dynamic penetration tester, which is suitable for various types of soil. The heavy dynamic penetration tester mainly consists of a probe, a penetration rod, and a 63.5kg hammer. During the test, the probe is drilled into the test point, and the hammer is dropped freely from a height of 76cm. The depth of the probe into the ground surface is recorded in time, and the number of blows is recorded for every 10cm of penetration. The engineering geological evaluation of the foundation bearing capacity is based on the number of blows, thus completing one hammer test. Therefore, it is necessary to design a building bearing capacity testing platform.
[0003] The existing penetrating test requires multiple hammer drops. Because the penetrating hammer is heavy, multiple people need to work together to lift it up again after the first drop, thus achieving a cyclical hammering test. This method increases the manpower and physical strength of the operators, and makes the subsequent operation more time-consuming and laborious. It is not convenient for operators to perform the hammering operation simply and easily. In addition, improper operation in the later stages also poses certain safety hazards. Utility Model Content
[0004] The purpose of this utility model is to provide a building load-bearing capacity testing platform with a simple structure and reasonable design in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A building load-bearing capacity testing platform includes a base, with automatic pull-out components fixedly installed on both sides of the top of the base. An installation sleeve plate is slidably fitted onto the outside of the automatic pull-out components. A hammering component penetrating into the base is threadedly fixedly installed at the middle position of the bottom of the installation sleeve plate. A drive component penetrating into the installation sleeve plate and cooperating with the hammering component is fixedly installed on the top of the installation sleeve plate.
[0007] As a further optimization of this utility model, the automatic pull-out assembly includes a drive screw rotatably mounted on one side of the top of the base. A mounting plate is fixedly mounted on the top of the drive screw. A servo motor is fixedly mounted on one side of the top of the mounting plate, and the output end of the servo motor is fixed to the top of the drive screw through the mounting plate. An internal threaded collar is threaded onto the top of the outer side of the drive screw, and multiple limiting holes are provided on the outside of the internal threaded collar.
[0008] As a further optimization of this utility model, the hammering assembly includes a limiting guide rod threadedly installed at the middle position of the bottom of the mounting plate. A through hammer is slidably fitted on the outside of the limiting guide rod. Multiple handles are fixedly installed on the outside of the through hammer. A hammering seat is threadedly installed on the bottom of the outside of the limiting guide rod. A probe rod penetrating the interior of the base is threadedly installed on the bottom of the hammering seat. A probe is threadedly installed on the bottom of the probe rod.
[0009] As a further optimization of this utility model, the driving assembly includes a cylinder fixedly installed at the middle position of the top of the mounting plate. A connecting rod is fixedly installed at the output end of the cylinder and slides through to both sides inside the mounting plate. Both sides of the bottom of the connecting rod are engaged with the outside of the grip. Limiting rods placed at the bottom of the grip are slidably inserted at the bottom of both ends of the connecting rod. Push blocks are fixedly installed at one end of the back of each of the two limiting rods. Springs that are fixed to the push blocks and the connecting rods are sleeved on the outside of each of the two limiting rods.
[0010] As a further optimization of this utility model, a guide rod is fixedly installed on the other side of the top of the base. The guide rod slides through to the other side of the mounting sleeve and is fixedly connected to the bottom of the mounting top plate.
[0011] As a further optimization of this utility model, the mounting sleeve is slidably fitted onto the outside of the drive screw and the guide rod. A mounting block is fixedly installed on the side of the mounting sleeve near the drive screw. The inner top thread of the mounting block extends through to a fixing screw that extends into the limiting hole. Push blocks one that cooperate with push blocks two are fixedly installed on both sides of one end of the back of the mounting sleeve.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The structural design of the drive component of this utility model, in conjunction with the use of the hammering component, can complete the automatic hammering work of the hammering component. It eliminates the need for multiple operators to work together to lift and let the hammer fall freely, reducing the convenience and flexibility of subsequent operations, reducing manpower and physical exertion, and increasing the automation performance and practicality of the testing platform in later operations.
[0014] 2. This utility model, through its automatic pull-out component structure design, can pull out the hammer component inserted into the ground, ensuring the convenience and flexibility of the subsequent hammer component pull-out operation.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0024] Example 1
[0025] like Figure 1 , Figure 2 , Figure 3As shown, a building load-bearing capacity testing platform includes a base 1. The structural design of the base 1 enables the installation and support of the testing platform and its components. An opening is provided in the middle of the interior of the base 1. Limiting rings are installed at the middle of both ends of the base 1, and grounding rods slide through the interior of both limiting rings. The structural design of the grounding rods and limiting rings improves the stability of the base 1 and its components during later placement. Automatic pull-out components 2 are fixedly installed on both sides of the top of the base 1. The automatic pull-out components 2 include a drive screw 200 rotatably mounted on one side of the top of the base 1. A mounting top plate 206 is fixedly installed on the top of the drive screw 200. A through groove is provided in the middle of the interior of the mounting top plate 206. A servo motor 20 is fixedly installed on one side of the top of the mounting top plate 206. 1. The servo motor 201 is externally fixed with a mounting bracket that is fixed to the top of the mounting plate 206. A coupling is fixedly installed at the output end of the bottom of the servo motor 201, and the coupling rotates through the interior of the mounting plate 206 and is fixedly connected to the top of the drive screw 200. The model of the servo motor 201 is Siemens 1FT7102. An internal threaded collar 205 is threaded on the top of the outer side of the drive screw 200. Multiple limiting holes 204 are opened on the outside of the internal threaded collar 205. Later, the operator can manually rotate and move the internal threaded collar 205 outside the drive screw 200. A guide rod is fixedly installed on the other side of the top of the base 1, and the top of the guide rod is fixedly connected to the bottom of the mounting plate 206 to ensure the stability of the mounting support of the base 1 and the mounting plate 206.
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a mounting plate 4 is slidably fitted onto the drive screw 200 and the guide rod. A hammering assembly 3, penetrating into the base 1, is threadedly fixed at the middle position of the bottom of the mounting plate 4. The hammering assembly 3's structural design facilitates subsequent hammering tests on the ground. The hammering assembly 3 includes a limiting guide rod 300 threadedly installed at the middle position of the bottom of the mounting plate 4. An internally threaded connecting cylinder is welded and fixed at the middle position of the bottom of the mounting plate 4. The internal thread of the internally threaded connecting cylinder is connected to the limiting guide rod 300. A through-hole hammer 303 is slidably fitted onto the outside of the limiting guide rod 300. The outside of the through-hole hammer 303... Multiple grips 305 are fixedly installed. A hammer seat 304 is threaded on the bottom of the outer side of the limiting guide rod 300. A probe rod 301 is threaded on the inner bottom of the hammer seat 304. The probe rod 301 has scale lines on its outside. The scale lines allow the operator to easily observe and know the insertion depth of the probe rod 301 in real time, which is convenient for the operator to calculate and evaluate later. The probe rod 301 extends to the outside through the opening in the base 1, which facilitates the contact and insertion operation with the ground. A probe 302 is threaded on the bottom of the probe rod 301. The probe design makes it easy to hammer and insert the probe into the ground to be tested.
[0027] like Figure 4 , Figure 5 , Figure 7 As shown, a drive assembly 5 is fixedly installed on the top of the mounting plate 4. Through the structural design of the drive assembly 5, automatic control of the hammer 303 can be easily achieved, eliminating the need for multiple operators to lift and strike the hammer, thus reducing the consumption of human strength. The drive assembly 5 includes a cylinder 500 fixedly installed at the middle position of the top of the mounting plate 4. A connecting plate located in the through groove inside the mounting plate 206 is fixedly installed at the output end of the cylinder 500. Connecting rods 501, which slide through to the inner sides of the mounting plate 4, are fixedly installed on both sides of the bottom of the connecting plate. A U-shaped opening groove is opened at the middle position of the bottom of each connecting rod 501, and the two U-shaped opening grooves engage with the outside of the handle 305. Both limit rods 505 are slidably inserted through the bottom of one end of the back of the part and are placed below the grip rod 305. The front end of the bottom of each limit rod 505 is provided with a guide slope, and the two guide slopes cooperate with the grip rod 305. Later, the arc shape of the grip rod 305 can resist the guide slope, and then complete the pushing work of the limit rod 505. The back end of each limit rod 505 is fixedly installed with a push block 2 503. The top of the front end of each push block 2 503 is provided with a guide slope 2. The outside of each limit rod 505 is fitted with a spring 504 that is fixed to the push block 2 503 and the connecting rod 501. The spring 504 can easily realize the reset work of the later displacement of the limit rod 505.
[0028] like Figure 1 , Figure 4 , Figure 6 , Figure 7 As shown, a mounting block 203 is fixedly mounted on the side of the mounting plate 4 near the drive screw 200. An internal threaded hole is provided at the center of the top of the mounting block 203. A fixing screw 202 passes through the internal thread of the internal threaded hole, allowing the fixing screw 202 to be inserted into the limiting hole 204. This facilitates the later fixed connection between the mounting plate 4 and the internal threaded collar 205. Then, through the threaded engagement between the drive screw 200 and the internal threaded collar 205, the mounting plate 4 and its components above it can be lifted outside the drive screw 200. This allows for the removal of the probe rod 301 and its components after the hammering is completed. Push blocks 502 are fixedly installed on both sides of one end of the back of the mounting plate 4. The bottom of the back of each push block 502 is provided with a guide slope 3. The guide slope 3 of push block 502 cooperates with the guide slope 2 of push block 503, so that push block 502 can push push block 503 later. Then, the limiting rod 505 moves inside the connecting rod 501 to stretch the spring 504. The movement of the limiting rod 505 can release the limit on the gripping rod 305, and then release the limit on the hammer 303. Finally, the hammer 303 can fall freely outside the limiting guide rod 300 to strike the probe rod 301.
[0029] It should be noted that, when using this type of building load-bearing capacity testing platform, the operator can first move the base 1 and above to the designated location, connect the power supply, and then... Figure 1 , Figure 2 , Figure 3In the initial state shown, the connecting rod 501 and its components within the mounting sleeve 4 can be lifted using cylinder 500. Furthermore, the engaging design between the gripping rod 305 and the limiting rod 505 facilitates the lifting of the mandrel 303 outside the limiting guide rod 300 during the movement of the connecting rod 501. This lifting method eliminates the need for multiple operators, reducing manpower and physical exertion. When the mandrel 303 is raised to the designated height, it can be lifted using push block 503. The guide slope design of push block 502 allows push block 502 to push push block 503, which in turn moves the limiting rod 505 inside the connecting rod 501, thus stretching the spring 504. The movement of the limiting rod 505 releases the limiting position on the gripping rod 305, thereby releasing the limiting position on the hammer 303. Finally, the hammer 303 can freely fall outside the limiting guide rod 300, striking the hammer seat 304. This, in turn, drives the probe rod 301 and the probe 302 through the interior of the base 1. Inserted into the ground, and with the probe 301 and probe 304 moving downwards, the mounting sleeve 4 and above components can be moved downwards outside the drive screw 200. Then, when the connecting rod 501 is moved downwards by the reverse operation of the cylinder 500, the U-shaped opening at the bottom of the connecting rod 501 and the guide slope at the bottom of the limiting rod 505 facilitate the downward movement of the limiting rod 505 by gripping the rod 305 and pushing it through the guide slope. The movable limit rod 505 moves inside the connecting rod 501 to stretch the spring 504. When the connecting rod 501 moves down to the designated position, the elastic restoring force of the spring 504 can drive the limit rod 505 and the above components to reset, so that the limit rod 505 can be placed below the handle 305, which facilitates the automatic locking and lifting of the through hammer 303 in the later cycle. This enables the intermittent hammering work of the through hammer 303 in the later stage, increasing the convenience and flexibility of the detection device in the later operation.
[0030] After the hammer test is completed, the operator can manually rotate the internal threaded collar 205 to move it downward outside the drive screw 200, so that the internal threaded collar 205 rotates and is placed on top of the mounting plate 4. Finally, the rotating fixing screw 202 moves inside the mounting block 203 and inserts into the limiting hole 204 opened on the outside of the internal threaded collar 205, thereby realizing the fixed connection between the internal threaded collar 205 and the mounting plate 4. Finally, the servo motor 201 is driven to rotate the drive screw 200, which can then realize the upward movement of the internal threaded collar 205, which drives the mounting plate 4 and the above components. This allows for easy removal of the probe rod 301 and probe 302 inserted into the ground without the need for manual removal by the operator, thus further ensuring the flexibility and practicality of the test station in later operation.
[0031] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
