Description

Technical Field

[0001] The invention relates to the technical field of pipeline emergency rescue, in particular to a portable aerial emergency rescue equipment for long-distance oil and gas pipelines. Background Art

[0002] Long-distance oil and gas pipelines are the core main pipelines for the inter-regional transmission and distribution of natural gas, and play a key role in the transmission and distribution of natural gas to urban gas distribution centers and industrial enterprises.

[0003] The suspended oil and gas long-distance pipeline incident is caused by the loss of soil around the pipeline and the loss of support at the bottom of the pipeline due to water scouring and other reasons, which may endanger production safety. The main reasons for the suspended pipeline are: the soil around the pipeline is hollowed out due to bad weather, and the third-party units of rivers and rivers illegally mine sand and stone, which leads to the gradual thinning of the soil covering the crossing section of the pipeline. At the same time, the suspended pipeline is very likely to cause serious deformation and distortion of the pipeline, and in severe cases, it may also cause the pipeline to break, and a large amount of natural gas leakage will cause extremely serious safety accidents.

[0004] In the face of poor traffic conditions in mountainous areas, large-scale engineering machinery is difficult to arrive in time, etc., which brings many inconveniences to the rescue mission of gas pipelines and increases the risk of leakage in long-distance oil and gas pipelines. Therefore, in order to improve the rescue speed, it is necessary to develop equipment for emergency rescue of long-distance natural gas pipeline suspension, enhance the convenience and timeliness of long-distance natural gas pipeline suspension, and a portable oil and gas long-distance pipeline suspension stabilizing device for emergency repair is very necessary. Summary of the invention

[0005] The purpose of the present invention is to overcome the difficulties in the above-mentioned existing problems and provide a portable emergency rescue equipment for suspended long-distance oil and gas pipelines, and to provide emergency handling equipment for the problem of oil and gas pipelines exposed to the ground when facing severe weather in complex environments such as mountainous areas.

The worm rod is driven to rotate by rotating the handwheel, and the turbine is driven to rotate. The rectangular thread arranged in the turbine interacts with the external thread of the screw to drive the screw to push the flange up or down. The shell is a sleeve to protect the turbine. The lifting assembly also includes a pull ring, a cover plate, and a sleeve. The cover plate is a flat plate used to support the lifting assembly, and the sleeve is used to protect the screw rod.

[0010] Furthermore, the support assembly includes four support side panels, a hinge rod and a clamping bolt. Adjacent support side panels are connected by a hinge rod to form a basic structural unit of the support assembly. The upper and lower structural units are connected by a clamping bolt and are modularly assembled according to the required height to achieve height adjustment.

[0011] Furthermore, the adjustment base includes a base plate and four adjustment legs. Four bosses are provided on the edge of the base plate. Threaded holes are opened on the bosses and are threadedly connected to the four adjustment legs.
