Description

Technical Field

[0001] The utility model relates to the technical field of workover machines, in particular to a workover machine with an anti-dumping support structure. Background Art

[0002] A workover rig is a specialized equipment used for downhole operations in oil fields. It is primarily used for the repair and overhaul of oil, gas, and water wells. It typically consists of a power system, a winch, a derrick, and other components. The rig can raise and lower downhole tools and equipment such as tubing and sucker rods, and perform operations such as sand flushing and salvage. Its efficient operational capabilities and reliability play a vital role in ensuring the normal production of oil fields.

[0003] The workover rig with an anti-dumping support structure is an optimized upgrade based on the traditional workover rig. It is equipped with a special support device that can effectively prevent tipping caused by uneven terrain, external impact or improper operation during operation. This type of workover rig enhances operational stability and safety, ensuring reliable operation under various complex working conditions.

[0004] The existing workover rig with an anti-dumping support structure also has the following problems: it has no vibration reduction function. When the workover rig is working, it can only be supported by various fixing tools to ensure that it does not dump. Since the drilling tool may cause severe vibration during operation, and the engine will also vibrate when working for a long time, long-term vibration will cause damage to the internal parts of the equipment and reduce its service life. In view of the above problems, a workover rig with an anti-dumping support structure is proposed. Utility Model Content
