DETAILED DESCRIPTION

[0020] The technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings of the utility model embodiment, so that the concept of the utility model, the solved technical problems, the technical features of the technical scheme and the brought technical effects can be further understood.

[0021] Example 1

[0022] As Figure 1 , Figure 2As shown, a bolt torque detection device includes a base plate 1, on which a drive motor 4 is mounted, and a torque sensor 2 is provided at the output end of the drive motor 4; it also includes a bolt sleeve 3, one end of which is used to fit a bolt, and the other end is provided with a first connecting sleeve 301, which is connected to the torque sensor 2; it also includes a connecting rod 6, one end of which is connected to the base plate 1, and the other end of which is provided with a fixing part.

[0023] A torque detection structure for the bolts to be tested is provided below the base plate 1. The torque detection structure consists of a drive motor 4, a torque sensor 2, and a bolt sleeve 3. After the base plate 1 is fixed by the connecting rod 6, the drive end of the drive motor 4 on the base plate 1 is in a fixed state. The drive motor 4 can drive the torque sensor 2 and the bolt sleeve 3 to rotate. However, after the bolt to be tested is fixed by the bolt sleeve 3, during the drive of the drive motor 4, the torque of the bolt to be tested is transmitted to the torque sensor 2 through the bolt sleeve 3. Then, the torque detection structure completes the torque detection of the installed bolt, ensuring that the bolt reaches the correct tightening torque during the tightening process, thereby ensuring the normal operation and safety of the equipment. During the testing process, after the base plate 1 is fixed by the connecting rod 6, no manual support is required for the testing device, that is, no skill level is required for the operator, the error is less likely to occur, and thus the efficiency is improved.

[0024] Furthermore, a second connecting sleeve 5 is provided at each of the four corners of the bottom of the substrate 1. There are four connecting rods 6, one connecting rod 6 corresponding to one second connecting sleeve 5. Each second connecting sleeve 5 has a first fixing hole 501, through which a screw can be passed to detachably connect the connecting rod 6. The installation of a connecting rod 6 at each of the four corners of the bottom of the substrate 1 increases the stability of the fixation. The first fixing hole 501 at the second connecting sleeve 5 allows for easy detachment of the connecting rod 6, making it more convenient to carry.

[0025] like Figure 3 As shown, the connecting rod 6 is further described as a telescopic sleeve, comprising a sliding sleeve 602 and a sliding rod 601. The sliding rod 601 is slidably connected within the sliding sleeve 602. A second fixing hole 603 is provided on the sliding sleeve 602, and a locking bolt is provided within the second fixing hole 603 for locking the sliding rod 601. The sliding connection between the sliding sleeve 602 and the sliding rod 601 allows the length of the telescopic sleeve as a whole to be adjustable. This ensures that during the fixing process of the connecting rod 6 in this embodiment, the bolt sleeve 3 can be directly adapted to the height of the bolt to be tested by adjusting the length of the telescopic sleeve, thus completing the fitting and fixing of the bolt sleeve 3 to the bolt to be tested.

[0026] Further, the substrate 1 is provided with two handles 101, which are arranged at the two ends of the upper surface of the substrate 1. The handles 101 facilitate the transportation and carrying of the embodiment.

[0027] Preferably, the fixing part is a suction cup 7. In the process of fixing the substrate 1 by the connecting rod 6, the environment is usually the wall of a tower drum, which is uneven and curved. The suction cup 7 can fix the connecting rod 6 to the wall of the tower drum.

[0028] Further, the connecting rod 6 is provided with an evacuation cylinder 8, which is connected to the inside of the suction cup 7 through a pipeline. The evacuation cylinder 8 is similar to a needle cylinder, which includes a cylinder and a piston. The air pressure in the cylinder can be changed by pulling the piston. The cylinder is connected to the inside of the suction cup 7. When the edge of the suction cup 7 is attached to the wall of the tower drum, pulling the piston outward can make the suction cup 7 tightly attached to the wall of the tower drum, thereby providing sufficient fixation for the connecting rod 6. Similar to the needle cylinder, the piston is attached to the inner wall of the cylinder. The piston is provided with a rubber structure. When the piston is pulled with force, the rubber structure does not affect the pulling of the piston. In the static state, the rubber structure of the piston has anti-sliding ability, which avoids the sliding of the piston due to the small air pressure in the cylinder, thereby affecting the fixation effect of the suction cup 7.
