The connecting block is provided with a second bolt hole, and the size of the second bolt hole matches the size of the bolt.

The tension conversion sensor (not shown in the figure) is connected to the wireless sensor through wires inside the tension conversion sensor installation body, and the wireless sensor is wirelessly connected to the wireless receiver on the display by emitting infrared rays.

The display has data display and early warning functions. The display can display the real-time force of the load-bearing tool in digital form, and can set early warning coefficients and has an alarm function.

The positive beneficial effect of the present invention is:

1. In the present invention, wireless transmission is used for data transmission, which is convenient for ground monitoring personnel to observe data changes in time, avoids equipment damage caused by too much tension, improves work efficiency, and reduces equipment investment.

2. The use of wireless transmission in the present invention reduces the construction inconvenience caused by the length limitation of the connecting wires and increases the practicability of the device.

3. The design of the protective door in the present invention prevents the tension conversion sensor from being corroded by dust and other substances, increases the service life of the device, and ensures the sensitivity of the device.

4. The setting of the display in the present invention can display the force of the device through the display screen, and can set the overload coefficient. When the preset coefficient is exceeded, an alarm can be prompted, which improves the construction safety.

5. The present invention is easy to understand, easy to operate, can improve the perception and controllability of the lifting device, and has good economic benefits.
