[0032] The utility model provides a detection tool for the inner cavity of a bridge box shaft.
[0033] A detection tool for the inner cavity of a bridge box shaft, the detection tool 2 includes a main body 21, the main body 21 is a plate-like structure, the middle part of the lower end face of the main body 21 can fit with the bottom of the inner cavity 1 of a standard-sized bridge box shaft, the two side parts of the lower end face of the main body 21 can fit with the side of the inner cavity 1 of the standard-sized bridge box shaft, and the opposite ends of the lower end face of the main body 21 are respectively provided with corners 22, and the two corners 22 can fit with the opposite ends of the top of the inner cavity 1 of the standard-sized bridge box shaft. The standard-sized bridge box shaft here means that theoretically the size of its inner cavity 1 is completely consistent with the standard inner cavity size.
[0034] When the utility model is in use, the bridge box shaft is placed in a vertical direction with its inner cavity 1 facing upwards, the main body 21 is held, and the middle part of the main body 21 is matched with the bottom of the inner cavity 1 of the bridge box shaft, the two side parts of the lower end face of the main body 21 are matched with the side faces of the inner cavity 1 of the bridge box shaft, and the two corners 22 are respectively matched with the opposite ends of the top of the inner cavity 1 of the bridge box shaft. By observing the gap between the lower end face of the main body 21 and the various parts of the inner cavity 1, the inner cavity 1 of the bridge box shaft can be preliminarily detected, and the bridge box shaft with a relatively obvious processing error in the inner cavity 1 can be quickly screened out. The screened out bridge box shaft does not need to be tested by the inner cavity streamlining device, thereby improving work efficiency.
[0035] The main body 21 includes: a first detection part 211, which is located in the middle position of the main body 21, and the lower end surface of the first detection part 211 can be fitted with the bottom of the inner cavity 1 of the standard-sized bridge box shaft; two second detection parts 212, which are respectively arranged on both sides of the first detection part 211, and the lower end surface of the second detection part 212 can be fitted with the first part 11 of the standard-sized bridge box shaft, and the second detection part 212 is inclined from one end connected to the first detection part 211 to the other end relative to the direction away from the first detection part 211. The second detection part 212 is inclined from one end connected to the first detection part 211 to the other end in a direction away from the first detection part 211. On the one hand, the matching length between the second detection part 212 and the first part 11 is increased, allowing the staff to better observe the size of the gap between the second detection part 212 and the first part 11 with the naked eye. On the other hand, the whole formed by the first detection part 211 and the two second detection parts 212 is not a straight plate structure, but a plate structure with bends at both ends, so that the first detection part 211 and the two second detection parts 212 can be placed more stably in the inner cavity 1 as a whole, so that the main body 21 can be placed more stably in the inner cavity 1.
[0036] The main body 21 also includes: two third detection parts 213, which are respectively arranged on the outside of the two second detection parts 212.

The third detection part 213 is inclined from one end connected to the second detection part 212 to the other end in a direction away from the first detection part 211. In a specific embodiment, the inclination angle of the third detection part 213 is smaller than the inclination angle of the second detection part 212. The inclination angle referred to here refers to the angle between the extension line of the first detection part 211 and the third detection part 213 or the second detection part 212. The inclination angle of the third detection part 213 is smaller than the inclination angle of the second detection part 212. It can be understood that the third detection part 213 is formed by bending in a direction close to the first detection part 211 on the basis of the second detection part 212. The third detection part 213 is inclined from one end connected to the second detection part 212 to the other end in a direction away from the first detection part 211. On the one hand, the matching length between the third detection part 213 and the second part 12 is increased, which allows the staff to better observe the size of the gap between the third detection part 213 and the second part 12 with the naked eye. On the other hand, the whole formed by the adjacent second detection part 212 and the third detection part 213 is not a straight plate structure, but a plate-like structure with a bent middle part, so that the second detection part 212 and the third detection part 213 as a whole can be placed more stably in the inner cavity 1, thereby allowing the main body 21 to be placed more stably in the inner cavity 1.
[0037] The main body 21 further includes two supporting portions 214 , which are respectively located outside the two third detection portions 213 , and a corner 22 is formed between the lower end surface of the supporting portion 214 and the lower end surface of the third detection portion 213 .
[0038] Positioning members (not shown) are respectively provided on two opposite side surfaces of the main body 21, and the positioning members include: a connecting plate 24, one end of which is fixedly connected to the supporting portion 214; a limiting rod 23, the limiting rod 23 passes through the connecting plate 24, the limiting rod 23 and the connecting plate 24 are limitedly matched, and a magnet 25 is provided on the lower end surface of the connecting plate 24. The lower end surface of the connecting plate 24 can be adsorbed and connected with the magnet 25. Before the main body 21 is placed, the magnet 25 is adsorbed on the connecting plate 24. After the main body 21 is placed, the limiting rod 23 is pressed downward to allow the magnet 25 to be adsorbed and connected to the end surface of the bridge box shaft, so that the main body 21 can be placed more stably in the inner cavity 1.
[0039] The main body 21 is integrally formed by bending.
