Description

Technical Field

[0001] The utility model belongs to the technical field of pipe pile detection, and in particular relates to a pipe pile bending resistance detection device. Background Art

[0002] Pipe piles, crucial foundation engineering components composed of steel pipes and concrete (or steel cages), are securely placed in the foundation through specific installation methods (such as driving or vibrating). They bear and transmit the loads from the building. Before the pipe piles are officially commissioned, quality control is crucial. Construction supervisors must rigorously inspect the piles, not only thoroughly examining their physical properties (such as specifications, models, dimensions, and appearance) and on-site storage conditions (such as stacking method and damage), but also commissioning qualified testing agencies to conduct random sampling inspections, focusing on their bending resistance to ensure that only qualified piles are used in actual projects.

[0003] The bending performance test of prestressed concrete pipe piles can be divided into three types: vertical downward loading, vertical upward loading and horizontal loading. This patent is aimed at the vertical downward loading method.

[0004] When testing the bending properties of conventional prestressed concrete, 1. a crane is required to lift the test pipe piles, which poses certain safety hazards; 2. the supporting pads need to be replaced according to the changes in pile length, which is time-consuming and labor-intensive.

[0022] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The present invention provides a device for testing the bending resistance of pipe piles. Figure 1-5 As shown, the bending resistance testing equipment for pipe piles includes: a support plate 1 with an opening in the center; a plurality of first hydraulic cylinders 2 fixedly mounted around the bottom of the support plate 1, with pads 3 fixedly mounted on the output rods of the plurality of first hydraulic cylinders 2; a bracket 4 fixedly mounted on the top of the support plate 1 to cover the opening; two clamping mechanisms mounted on the support plate 1 and located on both sides of the opening for fixing the pipe pile 10; a bending resistance testing mechanism mounted on the bracket 4 for pressing the pipe pile 10 through the opening; and two protective mechanisms arranged on the support plate 1 for shielding debris.

[0024] After the pile 10 is lifted up, the support plate 1 is lowered to the ground, and the pile 10 is lifted up to the ground.

[0025] In a further preferred embodiment of the present utility model, the clamping mechanism includes: a shell 5 slidingly connected to the bottom of the support plate 1, and the shell 5 is axially rotatably installed with a bidirectional screw 6; a motor 7 arranged on one side of the shell 5, and the output shaft of the motor 7 is fixedly connected to one end of the bidirectional screw 6; two connecting blocks 8 threadedly mounted on the two threaded sections of the bidirectional screw 6, and the two connecting blocks 8 are both slidably connected to the inner wall of the shell 5; two clamping blocks 9 respectively fixedly mounted on the two connecting blocks 8 for clamping the pipe pile 10, and the opposite surfaces of the two clamping blocks are provided with arc-shaped grooves, and the arc-shaped grooves are adapted to be fitted with rubber pads. When the two clamping blocks are closed, the two arc-shaped grooves form a circular groove that surrounds the lower half of the pipe pile, and the bottom of the opposite surfaces of the two arc-shaped grooves are detachably connected with a net bag.

[0026] In this embodiment, the clamping mechanism is used to secure the pipe pile 10. When the motor 7 is started, it drives the bidirectional screw 6 to rotate, which in turn drives the two connecting blocks 8 toward each other, allowing the two clamping blocks 9 to tightly clamp the pipe pile 10 placed on the ground, making it more convenient to use. When the size of the pipe pile changes, the position of the two housings on the support plate can be adjusted to ensure that the two clamping blocks maintain a stable grip on the pipe pile. At the same time, the two clamping blocks can accommodate pipe piles of different diameters, ensuring that the pipe pile is accommodated within the two clamping blocks. After the pipe pile is clamped, a net bag is connected to the bottom of the two arc-shaped grooves to prevent the pipe pile from falling out.

[0027] In a further preferred embodiment of the present invention, the bending resistance detection mechanism includes: a second hydraulic cylinder 11 fixedly installed in the center of the bracket 4, and a fixed plate 12 is fixedly installed on the output rod of the second hydraulic cylinder 11; a pressure sensor 13 fixedly installed at the bottom of the fixed plate 12, and a pressure plate 14 is fixedly installed at the bottom of the pressure sensor 13, and a slide groove is provided at the bottom of the pressure plate, and two U-shaped pads 21 are slidably connected in the slide groove.

[0028] In this embodiment, the bending resistance testing mechanism is used to press down on the pipe pile 10. During operation, the second hydraulic cylinder 11 is activated, which drives the fixed plate 12 to move vertically. The fixed plate 12 drives the pressing plate 14 to move vertically through the pressure sensor 13, so that the pressing plate 14 passes through the opening and presses down on the pipe pile 10 below. The two U-shaped pads contact the pipe pile, and the pressure generated by the downward pressure is detected by the pressure sensor 13. When the pressure reaches the appropriate value, the second hydraulic cylinder 11 is closed. If the pipe pile 10 is not damaged, the quality of the pipe pile 10 is qualified; otherwise, it is unqualified. When measuring pipe piles of different sizes, it is only necessary to adjust the distance between the two U-shaped pads.

[0029] In a further preferred embodiment of the present invention, the protective mechanism includes: a protective cover 15 slidably mounted on the support plate 1 and surrounding the bracket; two vertically distributed electric telescopic rods 16 fixedly mounted on the support plate 1, and positioning blocks 17 are fixedly mounted on the output rods of the two electric telescopic rods 16, and the two positioning blocks 17 are fixedly connected to the inner wall of the protective cover 15.

[0030] In this embodiment, the protective mechanism is used to block debris. When working, the electric telescopic rod 16 is started to drive the positioning block 17 to move vertically, and the positioning block 17 will drive the protective cover 15 to move vertically, so that the protective cover 15 blocks the pipe pile 10 to prevent the debris generated during the inspection process from splashing onto the worker's body, thereby improving the safety of the equipment during use.

[0031] In a further preferred embodiment of the present invention, a plurality of vertically distributed limiting rods 18 are slidably mounted on the bracket 4 , and the bottom ends of the plurality of limiting rods 18 are fixedly connected to the top of the fixing plate 12 .

[0032] In this embodiment, the use of multiple limiting rods 18 can improve the stability of the fixing plate 12 during vertical movement, and the problem of skewing is less likely to occur.

[0033] In a further preferred embodiment of the present invention, a protective shell 19 is fixedly installed on one side of the two housings 5 ​​, and the inner walls of the two protective shells 19 are fixedly connected to the two motors 7 respectively.

[0034] In this embodiment, the motor 7 can be stably mounted on one side of the housing 5 by using the protective shell 19 , while also providing the motor 7 with waterproof and dustproof effects.

[0035] In a further preferred embodiment of the present invention, a slide rod 20 is fixedly installed axially on the inner walls of the two shells 5, and the two slide rods 20 are respectively slidably connected to the multiple connecting blocks 8, and a control panel is fixedly installed on the top of the support plate 1.

[0036] In this embodiment, the use of the slide bar 20 can improve the stability of the connecting block 8 during movement, and the control panel can facilitate workers to control the electrical equipment of the device.

[0037] To sum up, compared with the relevant technology, this solution can facilitate workers to clamp and lift the pipe piles 10 placed on the ground through the coordinated use of multiple first hydraulic cylinders 2 and two clamping mechanisms, and then place the pipe piles 10 in a suitable position without manual lifting. Through the use of the bending resistance testing mechanism, the equipment can test the pipe piles 10 by pressing down. If the pipe piles 10 are not damaged under the corresponding pressure, the quality of the pipe piles 10 is qualified. Otherwise, it is unqualified. Through the use of the protective mechanism, the pipe piles 10 can be shielded when needed to prevent the debris generated during the testing process from splashing onto the workers' bodies. Therefore, compared with the relevant technology, this device can solve the problems of time-consuming and labor-intensive use and low safety of existing pipe pile bending resistance testing equipment, and has a better use effect.
