[0002] In railway engineering, catenary poles, guy wire bases, etc. are all connected to the catenary foundation through anchor bolts embedded in the foundation. However, during the construction process, due to insufficient length, different forms, etc. of the embedded anchor bolts, the embedding of the anchor bolts does not meet the design requirements. And because the structure embedded in the concrete belongs to a concealed project and cannot be directly judged from the appearance, it is necessary to use a detection device and a set of detection methods to judge whether its bearing capacity can meet the design requirements.

Detailed Embodiments

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1-2 , the present utility model provides a technical solution: an intelligent pulling and detecting device for railway anchor bolts, including an oil cylinder 1. One end of the oil cylinder 1 is provided with an oil injection nozzle 2 for injecting engine oil or hydraulic oil into the oil cylinder 1. The other end of the oil cylinder 1 is provided with an oil cylinder interface 4. The oil cylinder interface 4 is connected to one end of a high-pressure oil pipe 5. The other end of the high-pressure oil pipe 5 is connected to a jack oil pressure interface 6 of a jack 7. The host and the jack are connected through the high-pressure oil pipe 5 to sense and transmit the pressure generated when the jack pulls the bolt. The jack 7 is sleeved outside the embedded bolt 8. Before sleeving the jack 7, first install an anchor plate on the embedded screw 8 to make it in close contact with the ground, then sleeve the jack 7, and then install a fixture to make the jack 7 concentric with the embedded screw 8 to avoid phenomena such as eccentric tension or loosening.

[0019] The oil cylinder 1 is respectively provided with a pull rod 10 and a motor 11. The output shaft of the motor 11 is connected to a turntable 12. An eccentric rod 13 is installed at the edge of the side surface of the turntable 12. The end of the pull rod 10 is rotatably connected to the eccentric rod 13. The pull rod 10 is used to press the hydraulic oil in the oil cylinder 1 from the oil cylinder interface 4 through the high-pressure oil pipe 5 into the jack 7. The pull rod 10 specifically includes a fixed rod and a sliding rod. The sliding rod is slidably arranged in a chute opened on the side surface of one end of the fixed rod. The other end of the fixed rod is connected to the pressure rod of the oil cylinder 1. The end of the sliding rod is rotatably arranged outside the eccentric rod 13. When the motor 11 drives the eccentric rod 13 to rotate through the turntable 12, the sliding rod expands and contracts and rotates along with it, thereby driving the fixed rod to move up and down. The piston in the oil cylinder 1 is driven by the pressure rod to push the hydraulic oil and press it into the jack 7, so as to pull the embedded screw 8. The oil cylinder 1 is respectively provided with a pressure sensor 20 and a pressure display 14 connected to the pressure sensor 20. The pressure sensor 20 detects the pressure received and converts it into a digital signal through an analysis module in the pressure display 14 and displays it on the display screen for the staff to refer to. When the pressure value reaches the set detection value, the pulling and detecting can be stopped, and the state of the anchor rod and various data can be recorded, etc.

[0020] In a preferred technical solution, a pressure relief valve 3 is provided at the end of the oil cylinder 1 far from the oil cylinder interface 4 for relieving pressure after the pulling and detecting is completed.

[0021] In a preferred technical solution, an exhaust fan 9 is provided on the oil cylinder 1 for rapid heat dissipation and extending the service life of the device.

[0022] In a preferred technical solution, a fixing frame 15 is installed on the oil cylinder 1. A controller 16 and a built-in battery 22 for power supply are respectively arranged on the fixing frame 15. The built-in battery 22 is preferably a common rechargeable lithium-ion battery, which can perform detection work when the distance from the power supply is far or there is no power supply. The motor 11, the pressure sensor 20 and the exhaust fan 9 are all electrically connected to the controller 16. The controller 16 is preferably a common single-chip microcomputer or a PLC controller, etc., such as a PLC controller of the Siemens S7-200 series. The motor 11, the exhaust fan 9 and the pressure sensor 20 are intelligently controlled through the controller 16. After setting the pressure preset value through the controller 16, the motor 11 is turned on to perform the pulling test on the anchor bolt. During the pulling test, the pressure sensor 20 detects the pressure value and transmits it to the pressure display 14 and the controller 16 respectively. When the controller 16 determines that the pressure value reaches the set value, the motor 11 is automatically turned off, which improves the degree of automation and further improves the work efficiency.

[0023] For the traditional hydraulic pull tester, it is necessary for workers to record and collect the position of the anchor bolts for the pull test, the pull load data, and the image data during the pull process. It is very easy to cause inaccurate recording of the pull data, missing or loss of the pull data images, and even the occurrence of events of manual tampering with the pull data, which seriously affects the quality and safety of the project and leaves a great potential safety hazard for the safe operation of the catenary in the later stage. Therefore, we also propose a preferred technical solution. A camera 17 is installed at the top of the fixing frame 15. The camera 17 is electrically connected to the controller 16 and is used to capture the image data during the detection process. At the same time, a wireless transmission module 21 is arranged in the controller 16. The wireless transmission module 21 can adopt a common Wi-Fi module or a 5G communication module. The controller 16 is wirelessly connected to a handheld terminal 18 such as a PDA or a smart phone through the wireless transmission module 21. The controller 16 transmits various data such as the image data captured by the camera 17 and the pressure value detected by the pressure sensor 20 to the handheld terminal 18 through the wireless transmission module 21. The handheld terminal 18 is built-in with corresponding APP software to automatically save and prevent data tampering.

[0024] In a further preferred technical solution, the controller 16 is wirelessly connected to a cloud server 19 through the wireless transmission module 21. When the controller 16 transmits data to the handheld terminal 18, it can also upload the data to the cloud server 19 for storage through the wireless transmission module 21, which further avoids the possibility of data tampering and makes the data storage more secure.

[0025] The motor 11, built-in battery 22, controller 16, wireless transmission module 21, handheld terminal 18, cloud server 19, camera 17, exhaust fan 9, pressure sensor 20, pressure display 14, etc. used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, circuit connections, etc. are all well-known technologies and will not be elaborated here.

[0026] Furthermore, the camera 17 is movably arranged at the top of the fixing frame 15 through a gimbal, and the camera 17 can freely adjust its angle to be applicable to different usage scenarios.

[0027] The parts not disclosed in this utility model are all prior art, and their specific structures, materials and working principles will not be elaborated. Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
