The construction can only continue when the bolt torque reaches the design requirements. In order to meet the torque requirements, there will be potential safety hazards. The traditional torque detection device can only meet the detection function.

[0003] The patent with announcement number CN212275126U discloses a bolt torque detection device. By setting the tightening bolts and the top plate, the device can clamp the nut to be tested, making the device suitable for detecting bolts of various sizes and types; the setting of the clamping block enables the device to adjust the clamping height of the digital torque wrench according to the construction environment.

[0004] However, after the bolt is installed in the sleeve, during actual operation, the position of the sleeve needs to be fixed, and the position of the sleeve needs to be kept unchanged when the clamping handle is turned. It is difficult to fix the sleeve by holding the sleeve by hand. If the sleeve is installed on a platform, the platform will easily move when the clamping handle is turned, which is inconvenient to use.

[0005] Therefore, it is necessary to provide a bolt torque detection device to solve the above problems.

[0029] Among them, a pair of guide rods 14 are fixedly installed on the top of the bottom plate 11, and the pair of guide rods 14 are respectively located on both sides of the screw rod 13. The lifting platform 12 is sleeved and slidably connected to the outer surface of the guide rod 14 through a sliding bearing 121, so that the lifting platform 12 can slide stably in the longitudinal direction. A top plate 15 is provided on the top of the guide rod 14, and the bottom ends of the top plate 15 are respectively fixedly connected to the two guide rods 14. The screw rod 13 passes through the top plate 15 and is rotatably connected to the top plate 15, which can make the screw rod 13 and the guide rod 14 more stable.

[0030] like Figure 2-Figure 3 As shown, in this embodiment, a clamp 2 is further provided above the platform 1. The number of the clamps 2 is set to two groups. The two groups of clamps 2 are respectively installed on the top of the base plate 11 and the bottom of the lifting platform 12. The two ends of the bolt can be clamped separately by the two groups of clamps 2. By fixing one group of the clamps 2 and driving the other group of clamps 2 to rotate through the torque detector 4, the torque of the bolt can be measured.

[0031] One group of the clamps 2 can be driven to rotate by the motor 3. In the present embodiment, the motor 3 is fixedly mounted on the lifting platform 12, with the output end of the motor 3 facing downward.
