Detailed Implementation

[0019] The technical solutions in the embodiments of the application will now be clearly and completely described with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in one embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0020] It should also be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity from another, and do not necessarily require or imply any such actual relationship or order between these entities. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or terminal device that includes that element.

[0021] After processing and before use, pipe piles used in construction require various strength tests, such as the bending test of PHC pipe piles (PHC pipe piles are prestressed high-strength concrete pipe piles), to test their bending strength. Existing commonly used "downward-pressing" pipe pile bending test devices are used for this purpose. Chinese patent CN221399120U discloses a bending test device that uses a mobile trolley to transport the pipe pile to the test position. After the test, the trolley is moved to test other parts of the pipe pile. However, the trolley moves on a sliding rail, and due to the weight of the pipe pile, it experiences significant resistance during movement. Furthermore, placing the pipe pile on the trolley requires crane assistance, and removing it from the trolley after testing also requires crane assistance, making it inconvenient to use. Therefore, this utility model proposes a PHC pipe pile strength testing device that optimizes the mechanism for loading and unloading the pipe pile, thereby improving the convenience and practicality of pipe pile testing.

[0022] The following will be combined with the appendix Figures 1 to 5 This utility model will be described in detail. In the figures, the dashed circles or dashed frames represent pipe piles.

[0023] This utility model provides a PHC pipe pile strength testing device, such as Figure 1 As shown, the device includes a pressurizing assembly 3 for applying pressure to the pipe pile and a testing platform 1. The testing platform 1 and the pressurizing assembly 3 are mounted on a support platform 5. Two testing platforms 1 are located on both sides of the pressurizing assembly 3, and each testing platform 1 has a material conveying assembly 2 on its side. The material conveying assembly 2 includes: a pair of parallel support arms 21, a steel frame 22, and a lifting cable mechanism 23. The steel frame 22 is connected to the support arms 21. Figure 1 The structure of other steel frames 22 is not shown, but it can be understood that multiple steel frames 22, both transverse and longitudinal, are included below the support arm 21 to stabilize the support arm 21 and support the pipe pile. The lifting cable mechanism 23 includes: an arc plate 231, safety buckles at both ends of the arc plate 231, nylon straps 232 for connecting with the safety buckles, a steel cable for connecting with the arc plate 231, a pulley 233, a cable winding wheel 234 horizontally arranged with the pulley 233 and used for winding the steel cable, and a servo motor driven by the cable winding wheel 234. The pulley 233 is set below the support surface formed by the two support arms 21.

[0024] As described above, in this invention, material conveying components 2 are arranged on both sides of the testing platform 1 to allow the pipe pile to be tested or the tested pipe pile to move up and down (i.e., rise onto the testing platform and descend from the testing platform to the ground) using the material conveying components 2. During testing, a pressure-applying component 3, located between the two testing platforms 1, applies a vertically downward test pressure to the pipe pile. Specifically, the material conveying component 2 includes two opposing support arms 21 for bearing the weight of the pipe pile, and a steel cable for lifting the pipe pile is provided between the two support arms 21, such as... Figure 2As shown, the pipe pile is bound by the arc plate 231 and the nylon belt 232. The servo motor set under the test platform 1 drives the cable tie wheel 234 to rotate so that the steel cable is wound on the cable tie wheel 234 or released from the cable tie wheel 234. Correspondingly, the pipe pile to be tested is pulled up onto the test platform 1, and the tested pipe pile is released from the test platform 1.

[0025] Obviously, this utility model realizes the automatic delivery of pipe piles to the testing equipment, and the automatic removal of pipe piles from the testing equipment after the testing is completed. Moreover, the load capacity of this structure is stronger than that of the mobile trolley in the prior art. That is, it not only realizes the convenience or practicality of loading and unloading pipe piles when using the pipe pile bending strength testing equipment, but also increases the stability and safety of transporting pipe piles.

[0026] The nylon strap 232 is connected to the arc plate 231 by a safety buckle to facilitate the disassembly of the pipe pile. The nylon strap 232 can protect the surface of the pipe pile from damage by the steel cable and can increase compatibility with pipe piles of different diameters.

[0027] Specifically, such as Figure 1 As shown, the pressurizing assembly 3 includes a mounting base 31 that matches the track on the support platform 5, a symmetrical double gantry frame 32 connected to the mounting base 31, a pressure device, and a pressure rod 33 connected to the force-applying end of the pressure device. A pressure block 34 is provided between the bottom surface of the pressure rod 33 and the surface of the pipe pile. One side of the pressure block 34 is an arc-shaped surface that matches the surface of the pipe pile, and the other side is used to connect with the pressure rod 33 by bolts.

[0028] The double-gantry frame 32's structural design allows for simultaneous testing of two pipe piles on two testing platforms 1, thereby improving the testing efficiency of the testing device. Furthermore, the pressure assembly 3 moves left and right along the track on the support platform 5, enabling testing of different positions on the pipe pile. For example... Figure 3 As shown, the pressure block 34 is a transition piece between the pipe pile surface and the pressure rod 33. On one hand, it increases the force-bearing area of ​​the pressure block 34 applying pressure to the pipe pile surface, preventing slippage due to a small contact area. On the other hand, it evens out the pressure applied to the pipe pile by the pressure equipment. The surface of the pressure block 34 that contacts the pipe pile is an arc-shaped surface matching the outer surface of the pipe pile, while the opposite side is a flat surface used to connect with the end face of the pressure rod 33. The pressure block 34 and the pressure rod 33 are connected by bolts, facilitating the disassembly and replacement of the pressure block 34 when inspecting pipe piles of different diameters.

[0029] It should be noted that the aforementioned support arm 21 is fitted with a rigid silicone pad. This is because the rigid silicone pad can not only bear the weight of the pipe pile, but also has a smooth surface, which can reduce the frictional resistance between the outer surface of the pipe pile and the surface of the support arm 21. At the same time, it can also protect the pipe pile from damage by the support arm 21 during the up and down movement.

[0030] Furthermore, considering that the pressure equipment is compatible with testing pipe piles of different sizes, the pressure rod 33 needs to be lowered to different heights. Therefore, by setting adjustment blocks, the insufficient height difference can be compensated by increasing the number of adjustment blocks without changing the pressing height of the pressure rod 33. These adjustment blocks are manually added to the pressure equipment by the operator.

[0031] In some embodiments, such as Figure 5 As shown, the aforementioned testing platform 1 also includes a wedge-shaped limiting block 6, which is screwed to the surface of the testing platform 1. When the pipe pile is pulled up onto the testing platform 1, the operator needs to press the wedge-shaped limiting block 6 tightly against the pipe pile to position and fix the position of the pipe pile, so as to facilitate the positioning of the pipe pile by the pressurizing component 3 and prevent the pipe pile from sliding on the surface of the testing platform 1 during testing.

[0032] In some other embodiments, the PHC pipe pile strength testing device provided by this utility model also includes an auxiliary mechanism 4. The auxiliary mechanism 4 includes: a slide rod 41 arranged parallel to the steel frame 22, a base 42 sleeved with the slide rod 41 through the frame, a telescopic arm 43 connected to the base 42, and a screw motor driven by the base 42. The extension direction of the telescopic arm 43 is perpendicular to the installation direction of the base 42.

[0033] like Figure 4 As shown, to reduce the pulling force of the servo motor in lifting the pipe pile, an auxiliary mechanism 4 is provided between the two support arms 21 for pushing the pipe pile upward along the direction of the support arms 21. This auxiliary mechanism 4 is equipped with a telescopic arm 43 that can extend and retract vertically. Its telescopic design prevents interference with the pipe pile. The telescopic arm 43 extends and abuts against the outer wall of the pipe pile only when it is necessary to assist in pushing the pipe pile onto the testing platform 1 or lowering the pipe pile from the testing platform 1. The pushing base 42 extends along... Figure 4 The lead screw motor, which moves in the direction indicated by the middle arrow, is fixed to the steel frame 22. The extension and retraction of the lead screw causes the base 42 to move upward and downward. The telescopic arm 43 can be telescopically extended or retracted using a cylinder, piston, or other structure; this embodiment does not impose specific limitations on this. Furthermore, this auxiliary mechanism 4 effectively prevents the pipe pile from rolling off, further improving the safety of pipe pile transportation.

[0034] Finally, the present invention provides a PHC pipe pile strength testing device, including a pressurizing component 3 for applying pressure to the pipe pile and a testing platform 1. The testing platform 1 and the pressurizing component 3 are set on a support platform 5. Two testing platforms 1 are set on both sides of the pressurizing component 3. Material conveying components 2 are provided on both sides of the two testing platforms 1. The material conveying components 2 include: a pair of support arms 21 with parallel ends, a steel frame 22, and a lifting steel cable mechanism 23. The steel frame 22 is connected to the support arms 21. The lifting steel cable mechanism 23 includes: an arc plate 231, safety buckles set at both ends of the arc plate 231, a nylon belt 232 used to connect with the safety buckles, a steel cable used to connect with the arc plate 231, a guide wheel 233, a wire harness wheel 234 set horizontally with the guide wheel 233 and used to wind the steel cable, and a servo motor drivenly connected to the wire harness wheel 234. The guide wheel 233 is set below the support surface formed by the two support arms 21. This invention not only improves the convenience and practicality of using the pipe pile bending strength testing equipment for loading and unloading pipe piles, but also increases the stability and safety of transporting pipe piles.
