Description

Technical Field

[0001] The utility model relates to a folding bracket and an emergency self-rescue device for underground workers, belonging to the technical field of underground operation safety equipment. Background Art

[0002] Safety is always the primary consideration during the operation of small wells. There are many reasons for the leakage of toxic gases at the wellhead during the operation, including pipeline damage or aging, pressure imbalance in the well, gas accumulation in the well, gas invasion during drilling, and the influence of geological conditions. For example, certain geological conditions, such as caves and cracks, may cause toxic gases to accumulate in the formation and leak out through the wellhead.

[0003] In order to ensure the safety of the operators, safety first aid must be done in underground operations. The well environment needs to be monitored at all times during operations. If there is any abnormality, the operation should be stopped immediately and evacuated urgently. Traditional small well operations usually require the construction of a bracket, with support tripods built on both sides of the wellhead. A horizontal bar spans between the tripods at the top of the wellhead, and a rope roller is hung in the middle of the horizontal bar. The rope is then lowered or pulled by an electric motor or diesel engine on one side. When an emergency occurs, the underground personnel need to be raised urgently, and they need to call for help from the personnel outside the well and pull the rope to achieve the purpose of raising the personnel. Traditional brackets are used for small wellhead operations, which are extremely inconvenient to set up before the operation, and are not stable and cannot be reused. Utility Model Content

[0010] Based on the same inventive concept, the utility model also provides an emergency self-rescue device for underground workers, which can be conveniently set up on a small wellhead for lifting and lowering of workers.

[0020] 4. The central axis pin of the utility model can rotate around the pin, that is, the first cushion member and the second cushion member can rotate relatively to form a folded and stowed state to prevent the end of the support rod from squeezing the buckle when the support rod is folded and closed.

[0021] 5. The support rod of the utility model is a telescopic rod, on which a limit pin is arranged, and the length of the support rod is adjustable, so that it is applicable to wellheads of more sizes.

[0022] 6. In the utility model of the emergency self-rescue device for underground workers, the workers carry the monitoring components at all times.
