Fixed devices are symmetrically arranged at the bottom end of the base, and a support rod is fixedly connected to the top end of the base. An adjusting cylinder is sleeved and connected to the outer wall of the support rod. A threaded hole adapted to the thread on the outer wall of the support rod is opened in the inner wall of the adjusting cylinder, and a mounting plate is fixedly connected to the top end of the adjusting cylinder. A mounting seat is rotatably connected to the middle of the mounting plate through a bearing. Positioning devices are symmetrically arranged on both sides of the mounting seat and are located on the mounting plate. The positioning devices are provided with insertion holes at intervals corresponding to the outer wall of the mounting seat. A placing table is arranged above the insertion holes and is located at the top end of the mounting seat. By setting a screwing handle on the base to drive a screw rod, and at the same time, the fixed sleeve slides vertically along the chute through the cooperation of a sliding rod and a sliding block, thereby driving the screw rod to stretch in the fixed cylinder and driving the insertion pile to insert into the construction site, and then fixing the device on the ground, which improves the stability of the device.

[0004] However, the above device still has deficiencies:

[0005] During the detection, the ground of some detections is uneven, resulting in the device not being able to maintain a horizontal state, which will affect the final detection result of the device. Content of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides an engineering quality detection device for subway construction, which solves the problem that during the detection, the ground of some detections is uneven, resulting in the device not being able to maintain a horizontal state, which will affect the final detection result of the device.

[0007] To achieve the above object, the utility model provides an engineering quality detection device for subway construction, which includes an outer telescopic rod. A base is fixedly connected to the bottom of the outer telescopic rod. A balance component is arranged inside the base, where:

[0008] The balance assembly includes a first circular shaft rotatably connected inside the base. The first circular shaft is arranged at the center of the base. A main balance rod is rotatably connected to the outer side of the first circular shaft. Second circular shafts are rotatably connected to both ends of the main balance rod. The second circular shafts are arranged on the side of the main balance rod away from the first circular shaft. A secondary balance rod is rotatably connected to the outer side of the second circular shafts. Third circular shafts are rotatably connected to both ends of the secondary balance rod. A support rod is fixedly connected to the outer side of the third circular shafts.

[0009] Preferably, an inner telescopic rod is slidably connected inside the outer telescopic rod, and a fixing bolt is threadedly connected to the side wall of the outer telescopic rod.

[0010] Preferably, a detection platform is fixedly connected to the top of the inner telescopic rod, and a battery is fixedly connected to the top of the detection platform.

[0011] Preferably, a baffle is clamped inside the base, and through holes are formed on the surface of the baffle.

[0012] Preferably, the bottom of the support rod penetrates through the through hole and extends to the outside of the baffle.

[0013] Preferably, a limiting plate is fixedly connected to the top of the battery, a limiting rod is fixedly connected inside the limiting plate, and a detection workpiece is rotatably connected to the outer side of the limiting rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] Through the setting of the balance assembly, when the device encounters an inclined ground, because the first circular shaft, the second circular shaft and the third circular shaft have the property of support, and secondly, the overall center of gravity of the base is all supported on the first circular shaft, so no matter how the main balance rod and the secondary balance rod are adjusted and changed, the base is always supported by the first circular shaft, so the base will always remain in a horizontal state. Secondly, the main balance rod and the secondary balance rod will move with the first circular shaft and the second circular shaft as the fulcrums. One end of the main balance rod will fall towards the lower place while the other end will rise. The movement of the secondary balance rod is the same as that of the main balance rod. In this way, the balance assembly can automatically adapt to the inclination of the ground.

[0016] The advantage of such a design is that by automatically adapting to the ground inclination, the device can ensure a stable posture under various terrain and geological conditions, which helps to reduce measurement errors caused by uneven ground and improve the accuracy of detection results.

[0017] Secondly, the balancing component can adapt to more construction environments and scenarios, which greatly expands the application scope of the device, improves its flexibility and practicality, reduces human intervention, and enhances construction safety. A stable and reliable engineering quality detection device helps to promptly detect and warn of potential quality problems, avoiding the occurrence of safety accidents. It can automatically adapt to ground inclination, enabling the device to better serve construction safety monitoring and risk assessment, and ensuring the safety of construction workers and subway operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. 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.

[0024] As Figures 1-4 shown, an engineering quality detection device for subway construction is characterized in that it includes an outer telescopic rod 1, an inner telescopic rod 2 is slidably connected inside the outer telescopic rod 1, and a fixing bolt 3 is threadedly connected to the side wall of the outer telescopic rod 1. By stretching or retracting the inner telescopic rod 2, the overall height of the device can be adjusted, making its application scope wider. After adjusting the height, tighten the fixing bolt 3.

[0025] The top of the inner telescopic rod 2 is fixedly connected with a detection platform 4, and the top of the detection platform 4 is fixedly connected with a battery 5.

[0026] A limiting plate 6 is fixedly connected to the top of the battery 5. A limiting rod 61 is fixedly connected to the inside of the limiting plate 6. A detection workpiece 62 is rotatably connected to the outside of the limiting rod 61.

[0027] A base 7 is fixedly connected to the bottom of the outer telescopic rod 1. A balance assembly 8 is arranged inside the base 7.

[0028] The balance assembly 8 includes a first circular shaft 81. When the device encounters an inclined ground, the overall center of gravity of the base 7 is entirely supported on the first circular shaft 81. The first circular shaft 81 is rotatably connected inside the base 7. The first circular shaft 81 is arranged at the center of the base 7. A main balance rod 82 is rotatably connected to the outside of the first circular shaft 81. Second circular shafts 83 are rotatably connected to both ends of the main balance rod 82. The second circular shafts 83 are arranged on the side of the main balance rod 82 away from the first circular shaft 81. A secondary balance rod 84 is rotatably connected to the outside of the second circular shafts 83. No matter how the main balance rod 82 and the secondary balance rod 84 are adjusted and changed, the base 7 is always supported by the first circular shaft 81. Therefore, the base 7 will always maintain a horizontal state. Third circular shafts 85 are rotatably connected to both ends of the secondary balance rod 84. The main balance rod 82 and the secondary balance rod 84 will move with the first circular shaft 81 and the second circular shafts 83 as fulcrums. One end of the main balance rod 82 will fall towards the lower place while the other end will rise. The movement of the secondary balance rod 84 is the same as that of the main balance rod 82. In this way, the balance assembly 8 can automatically adapt to the inclination of the ground. A support rod 86 is fixedly connected to the outside of the third circular shaft 85.

[0029] By automatically adapting to the ground inclination, the device can ensure a stable posture under various terrain and geological conditions. This helps to reduce measurement errors caused by uneven ground and improve the accuracy of detection results.

[0030] Secondly, the balance assembly 8 can adapt to more construction environments and scenarios. This greatly expands the application range of the device, improves its flexibility and practicality, reduces human intervention, and improves construction safety. A stable and reliable engineering quality detection device helps to detect and warn potential quality problems in a timely manner, avoid the occurrence of safety accidents. By automatically adapting to the ground inclination, the device can better serve construction safety monitoring and risk assessment, and ensure the safety of construction workers and subway operation.

[0031] A baffle 71 is snap - connected inside the base 7. Through - holes 72 are formed on the surface of the baffle 71.

[0032] The bottom of the support rod 86 penetrates through the through - hole 72 and extends to the outside of the baffle 71.

[0033] Working principle: When the device encounters an inclined ground, because the first circular shaft 81, the second circular shaft 83, and the third circular shaft 85 have the property of support, and secondly, the overall center of gravity of the base 7 is all supported on the first circular shaft 81, so no matter how the main balance rod 82 and the auxiliary balance rod 84 are adjusted and changed, the base 7 is always supported by the first circular shaft 81, so the base 7 will always remain in a horizontal state. Secondly, the main balance rod 82 and the auxiliary balance rod 84 will move with the first circular shaft 81 and the second circular shaft 83 as the fulcrums. One end of the main balance rod 82 will fall to the lower place while the other end will rise. The movement of the auxiliary balance rod 84 is the same as that of the main balance rod 82. In this way, the balance assembly 8 can automatically adapt to the inclination of the ground.

[0034] After the overall balance of the device, the staff can detect the project by operating tools such as the control panel.

[0035] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it.
