[0014] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] A tensile force detection device for engineering inspection comprises a tensile force detector 1, a detection box 3 is arranged between two clamps 2 of the tensile force detector 1, a through hole 4 is arranged at the top and bottom central positions of the detection box 3, a vertical pipe 5 is arranged on each side of the detection box 3, a plurality of nozzles 6 are arranged on the side of the vertical pipe 5 facing the central position of the detection box 3, the top of the vertical pipe 5 is connected with a connecting pipe 18, the other end of the connecting pipe 18 is located at the bottom of an acid storage device 7, an acid pump 17 is arranged on the connecting pipe 18, a plugging device is arranged on the periphery of the through hole 4 at the bottom of the detection box 3, and the two sides of the detection box 3 are fixedly connected to the base of the tensile force detector 1 through vertical plates 8. When the utility model is used, the steel bar is first passed through the two through holes 4, and then the two ends of the steel bar are clamped by the two clamps 2, and then the gap between the steel bar and the through hole 4 at the bottom of the detection box 3 is blocked by the blocking device, and then the two acid pumps 17 are turned on to pass the acid through the connecting pipe 18 and the vertical pipe 5 and finally through the nozzle 6 to spray toward the steel bar, thereby continuously corroding the steel bar, simulating the situation in actual use where the steel bar is corroded to a certain extent after long-term use, and then the tensile test is carried out after spraying for a certain period of time.
[0016] Specifically, the blocking device described in this embodiment includes two electric push rods 9 symmetrically arranged with the through hole 4 at the bottom of the detection box 3 as the center, the electric push rods 9 are arranged at the bottom of the detection box 3, and the electric push rods 9 are arranged with an arc plate 10 at one end facing the through hole, and a corrosion-resistant rubber layer 11 is arranged inside the arc plate 10. The electric push rods 9 can conveniently drive the arc plate 10 and the rubber layer 11 to move, and at the same time, the two arc plates 10 and the rubber layer 11 can closely cooperate with the steel bars, thereby ensuring that the gap between the steel bars and the through hole 4 at the bottom of the detection box 3 is blocked.
[0017] Specifically, the detection box 3 described in this embodiment is provided with a corrosion-resistant coating layer 12. The corrosion-resistant coating layer 12 can ensure that the detection box 3 can be used stably for a long time.

After the acid liquid is sprayed, the liquid outlet valve 14 and the liquid outlet pump 15 are opened to discharge the acid liquid in the detection box 3, and then the blocking device is opened, so as to avoid the situation that the acid liquid cannot be discharged from the gap between the steel bar and the through hole 4 at the bottom of the detection box 3, thereby causing damage to the external equipment.

Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
