The unsafe state of the hydraulic twisting machine in use is as follows:

1. The hydraulic twisting machine does not have an anti-squeeze hand device. Some of the twisting machines currently used in our factory belong to this category. There is no protective device in the design of this twist button machine, which has equipment defects and is prone to hand squeeze accidents. 2. Although the hydraulic twisting machine is equipped with an anti-squeeze hand device, it is not applicable due to complicated procedures, and the author removed it. In the past few years, almost all of the products introduced by our factory were of this type.

The products are all equipped with protective baffles when they leave the factory. However, due to the unreasonable design of this protective baffle, it is not convenient to enter and exit the oil pipe. The operator removes all the protective baffles for convenience. accident hazard. Combined with the actual situation of the use of twisting machines, the following preventive measures are put forward: 1. It is necessary to continuously strengthen safety education, improve the safety awareness of operators, and make operators consciously abide by the post operation rules.

2. Regularly strengthen safety technical training, operators should be certified to work, improve the safety and technical quality of operators, and prevent illegal operation and illegal command. 3. Avoid fatigue work, avoid dozing time in the early morning, and let employees take a break during this period.

4. Combined with the actual situation, increase the efforts to tackle key problems in safety technology, and develop a suitable anti-squeeze device for hydraulic twisting machines, which essentially eliminates hidden dangers of accidents. 5. The automatic oil unloading device is selected, so that the oil and water generated by the operation automatically fall into the wellbore, which does not pollute the site and maintains a clean operating environment. 6. Regularly overhaul the hydraulic twisting machine and replace the jaws to cut off the hydraulic source. 7. Add eye-catching safety warning signs.
