[0037] The embodiments of the present utility model are described in detail below.

[0038] Example 1

[0039] See also Figures 1 to 12 The self-movable crawler static load detection platform provided by the utility model comprises a static load platform 1, a counterweight block group 3 arranged on the static load platform 1, a main hydraulic station 2 for power supply, a detection cylinder 9 and a chassis 8 arranged at the bottom of the static load platform 1;

[0040] The static load platform 1 and the chassis 8 are movably connected via a slewing bearing 14;

[0041] The chassis 8 is provided with crawler-type walking mechanisms 4 at opposite ends, and a loading space for applying force to the pipe pile to be tested is formed between the bottom of the chassis 8 and the inner side of the crawler-type walking mechanism 4, and a retractable testing oil cylinder piston rod 10 is provided in the loading space;

[0042] The chassis 8 and the static load platform 1 are provided with through grooves matching the detection cylinder 9 , and the detection cylinder 9 passes through the through grooves and is fixedly connected to the detection cylinder piston rod 10 .

[0043] Traditional detection cylinders are mostly independent detection cylinders. When performing static load testing, they need to be manually installed and fixed on the corresponding testing platform. After the test is completed, they need to be manually disassembled, and manual handling and installation are required during this process. In the combination of the detection cylinder and the static load platform, the detection cylinder can move with the static load platform as a whole. After it is in place, the detection cylinder can be extended or retracted by directly operating the operating button (or operating lever) of the electric control box; the walking mechanism combined with the high-precision positioning system can realize intelligent movement.

[0044] A group of outrigger oil cylinders 7 are respectively provided at both ends of the length direction of the static load platform 1, and each group of outrigger oil cylinders 7 is provided with two; the lower end of each group of outrigger oil cylinders 7 is also connected to an outrigger hull 6, which is a rectangular support plate matched with the outrigger oil cylinder 7. The support plate serves as the contact surface of the bottom of the outrigger oil cylinder, distributing the weight of the platform to a larger area, reducing the pressure on the ground, and preventing the platform from sinking or tilting.

[0045] The detection oil cylinder 9 includes a detection oil cylinder barrel 11, a pressure maintaining device 13, and an oil pipe arranged parallel to the length direction of the detection oil cylinder barrel 11, and the pressure maintaining device 13 is connected to the oil pipe.

[0046] The static load platform 1 is also provided with an electric control box 15 and a positioning display screen 16 ; the electric control box 15 is electrically connected to the main hydraulic station 2 , the detection cylinder 9 , the pressure maintaining device 13 , and the positioning display screen 16 .

[0047] The electric control box 15 can monitor the operating status of each device on the platform in real time, such as the pressure, displacement, speed and other parameters of the oil cylinder, and feed back the information to the operator, so that the operator can understand the operating status of the platform. The electric control box can collect data during the detection process, such as pile top displacement, loading force and other parameters, and store them for subsequent analysis and management.

[0048] The positioning display screen can display the real-time position of the platform, making it easier for operators to understand the movement trajectory of the platform and ensure that the platform reaches the detection location accurately. The positioning display screen can display the displacement data of the pile top in real time, making it easier for operators to monitor the detection process, detect abnormal conditions in time, and ensure the safety of the detection. The positioning display screen can assist the platform in navigation, for example, through the GPS positioning system, to guide the platform to the designated detection location.

[0049] The outrigger oil cylinder 7 is controlled by the electric control box 15, and can be telescopically adjusted to adjust the height and horizontal position of the platform to adapt to different terrains and ground conditions, ensuring that the static load platform remains stable during the detection process and avoids tilting or shaking.

[0050] The specific method for performing static load detection of each part (each station, process) using the device provided by the utility model adopts the conventional process flow in the prior art, which will not be specifically introduced here.

[0051] The utility model adopts a crawler-type walking mechanism on its chassis through various structural improvements. Compared with the traditional wheeled or hoisting methods, it has a faster moving speed and strong adaptability, and can be quickly transferred to different testing locations, greatly saving testing time and labor costs. The improved testing platform of the utility model can be moved as a whole, and does not need to be disassembled and rebuilt after each pile is tested as in the traditional method, saving a lot of time and labor costs. It can move by itself without a crane or other auxiliary equipment, reducing the transfer time and improving the testing efficiency.

[0052] Example 2

[0053] See also Figures 1 to 12 This example is improved on the basis of Example 1. A cylinder protection cover 12 is also provided on the upper part of the detection cylinder 9. Fig.10 , Fig.12 The oil cylinder protection cover 12 is fixedly connected to the static load platform 1; the oil cylinder protection cover 12 includes a fixed plate at the bottom and a protection cover at the top, the fixed plate is provided with a through hole matching the detection oil cylinder 9 and the oil pipe; the detection oil cylinder barrel 11 partially passes through the through hole. The provision of the oil cylinder protection cover 12 can prevent the counterweight block group (3) from being displaced during installation and detection and causing damage to the detection oil cylinder 9.

[0054] The pressure maintaining device 13 is a solenoid valve.

[0055] The slewing bearing 14 includes an inner ring, an outer ring and rolling elements; the detection cylinder 9 passes through the slewing bearing 14 and is fixedly connected to the detection cylinder piston rod 10, see Figure 5 , see Figure 6The slewing bearing is an existing mechanical component, which is composed of inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing that can withstand comprehensive loads and can withstand large axial and radial loads and overturning moments at the same time. The use of the slewing bearing can adjust the angle of the static load platform 1 while keeping the chassis stationary, thereby changing the center of gravity position of the static load platform.

[0056] The crawler-type walking mechanism 4 includes a driving wheel, a crawler, a supporting roller, a crawler tensioning device, a guide wheel, a sprocket wheel, a connecting supporting roller and a body suspension. Compared with wheeled machines with the same horsepower, the crawler has a large supporting surface and a small ground pressure (generally less than 0.1 MPa), so the sinking depth on soft soil is small, and thus the rolling resistance is small, which is conducive to exerting a larger traction force. Therefore, this improvement can ensure that the static load platform 1 works stably, regardless of the soft mud terrain of the construction site, and further improve the detection efficiency.

[0057] The static load platform 1 is also provided with a guardrail for fixing the counterweight block group 3, and a warning sign is provided on the guardrail.

[0058] The end of the static load platform 1 that is away from the main hydraulic station 2 in the length direction is also provided with a detection cylinder hydraulic station 5. The detection cylinder hydraulic station 5 is a power supplement for the load platform; in order to ensure that the load platform can still work normally when the load is too high, when the main hydraulic station 2 is insufficient in power, the electric control box detects the abnormality and activates the detection cylinder hydraulic station 5 to cooperate with the main hydraulic station 2 to reduce the load of the main hydraulic station 2.

[0059] In summary, the above embodiments of the utility model have achieved structural improvements in many aspects. The detection platform has a fast moving speed and strong adaptability. The center of gravity can be adjusted during the pile detection process, which greatly improves the detection efficiency and shortens the construction period. The platform adopts an integral structure, which is convenient and quick to disassemble. There is no need for complicated disassembly and assembly procedures, which saves time and labor costs. An electric control box and a positioning display screen are provided on the platform, which can monitor the displacement of the pile top in real time, detect abnormal conditions in time, and ensure the safety of detection. The detection platform can work independently with the help of GPS positioning, reducing communication failures during use, thereby improving the working efficiency and stability of the detection platform. A retractable detection cylinder piston rod is provided in the loading space, which can be adjusted according to different pile diameters and has strong adaptability; a pressure maintaining device is provided on the detection cylinder to keep the loading force stable and ensure the accuracy of the detection results; the static load platform and the chassis are movably connected through a slewing bearing to ensure the stability and safety of the platform.

[0060] Our company produces and uses the prototype of the self-moving crawler static load detection platform equipment of the utility model. It has been tested in actual engineering applications under confidentiality conditions and has been measured on multiple construction sites. The main performance parameters are shown in Table 1. The test results show that the detection platform has a fast moving speed and saves time: compared with the traditional wheeled or hoisting method, the crawler walking mechanism has better mobility and can be quickly transferred to different detection locations, greatly saving detection time and labor costs; good overall mobility: the detection platform can be moved as a whole, and there is no need to disassemble and rebuild each time a pile is detected as in the traditional way, saving a lot of time and labor costs, and it can move by itself without a crane or other auxiliary equipment, reducing transfer time and improving detection efficiency; the center of gravity is adjustable and has strong adaptability: the platform adopts a slewing bearing to connect the static load platform and the chassis, and the center of gravity can be adjusted during the detection process to adapt to the detection needs of different pile diameters and pile types and improve detection efficiency.
