Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-7 , the present invention provides a technical solution: a device for detecting the vertical uplift bearing capacity of a foundation, including a fixed column 1, a connecting column 2, a supporting column 3, a fixing bolt 4, a supporting seat 5, a moving wheel 6, a fixing pin 7, a hydraulic cylinder 8, a movable plate 9, a movable column 10, an auxiliary side plate 11, a clamping assembly 12, a fixed clamping plate 13, a connecting plate 14, a fixed rod 15, a fixing cap 16 and a load cell 17.

[0032] When using the device for detecting the vertical uplift bearing capacity of the foundation, as Figure 1 and Figure 3 shown, both the left and right sides of the fixed column 1 are fixedly connected with connecting columns 2, and the connecting columns 2 are connected through the supporting column 3. At the same time, the lower end of the supporting column 3 is fixedly connected with a supporting seat 5, and the lower end of the supporting seat 5 is fixedly installed with a moving wheel 6. First, the detection device is driven by the moving wheel 6 to move to the corresponding detection position, so that the uplift pile to be detected is placed in the middle of the lower end of the fixed column 1, and the uplift pile is located between the auxiliary side plates 11 on the left and right sides. After moving to the corresponding position, the fixing pin 7 is inserted at equal angles at the edge of the lower end of the supporting seat 5, and at the same time, the lower end of the fixing pin 7 is inserted into the ground, thereby facilitating the positioning of the detection device;

[0033] Then, according to the height of the uplift pile, as Figure 1 , Figure 2 and Figure 4As shown, by pulling the connecting column 2, the connecting column 2 slides between the fixed column 1. The connecting column 2 drives the auxiliary side plate 11 to rise and fall, so that the auxiliary side plate 11 drives the clamping assembly 12 to move to the position where the anti-pulling pile is clamped. Then, by rotating the fixing bolt 4, the fixing bolt 4 is threadedly connected to both the support column 3 and the connecting column 2. The fixing bolt 4 limits the position between the support column 3 and the connecting column 2. Combining Figure 5 , Figure 6 and Figure 7 shown, the clamping assemblies 12 are symmetrically arranged on the front and rear sides of the lower end of the fixed column 1. And the clamping assembly 12 includes a fixed clamping plate 13 for clamping, connecting plates 14 fixedly connected to the left and right ends of the fixed clamping plate 13, a fixed rod 15 for connection, a fixed cap 16 for locking and limiting, and a load sensor 17 fixedly installed on the inner side of the fixed clamping plate 13;

[0034] The fixed rods 15 are respectively fixedly connected to the front and rear sides of the auxiliary side plate 11. The fixed clamping plate 13 drives the connecting plate 14 to sleeved on the outer side of the fixed rod 15. Then, by rotating the fixed cap 16 threadedly connected to the outer surface of the fixed rod 15, the fixed cap 16 is in a fitting arrangement with the connecting plate 14. By the fixed cap 16 pushing the connecting plate 14 to slide between the auxiliary side plate 11, the fixed clamping plate 13 is driven to stably clamp the anti-pulling pile. At the same time, a load sensor 17 is fixedly installed on the inner side of the fixed clamping plate 13. The magnitude of the anti-pulling bearing capacity can be detected by the load sensor 17. After the clamping is completed, the hydraulic cylinder 8 installed at the upper end of the fixed column 1 is started. The output end of the hydraulic cylinder 8 is fixedly connected with a movable plate 9. And the movable column 10 is telescopically connected to the fixed column 1. At the same time, the movable plate 9 and the movable column 10 are connected to the auxiliary side plate 11. By the hydraulic cylinder 8 driving the movable plate 9 to move upward, the bearing capacity of the anti-pulling pile is detected.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
