Description

Technical Field

[0001] The utility model relates to the technical field of well repair machines, in particular to a well repair machine with a dustproof function. Background Art

[0002] A workover rig is a piece of equipment used in oil and gas exploration, mainly used to provide power and support during the drilling process. A workover rig is usually mounted on a truck or other special carrier and is used to drill wells, extract water or take samples. A workover rig can provide enough power and torque to complete the drilling operation, while also being stable and reliable.

[0003] The well repair rigs currently used have dust filters that prevent dust from entering the interior. After a period of use, a large amount of dust will accumulate on the filters, causing them to become clogged. If they are not cleaned for a long time, their filtering effect will also decrease. The filters are generally fixedly installed on the well repair rigs. This installation method makes it inconvenient for workers to disassemble and clean the filters. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide a well repairing machine with a dustproof function, which can solve the problem that the dustproof filter screen used in the well repairing machine currently used to prevent dust from entering the inside will accumulate a large amount of dust on the filter screen after being used for a period of time, causing it to be blocked. If it is not cleaned for a long time, its filtering effect will also be reduced. The filter screen is generally fixedly installed on the well repairing machine. This installation method makes it inconvenient for the staff to disassemble and clean the filter screen.

The shaft 8 rotates, the two transmission shafts 8 synchronously drive the two sprocket wheels 9 to rotate, the two sprocket wheels 9 synchronously drive the two chains 10 to rotate, and the two chains 10 synchronously drive the winch to work. The device can play the function of auxiliary transmission when the workover rig is lifting heavy objects, so as to avoid the workover rig only operating through the hydraulic push rod in its own winch when lifting heavy objects, which may cause the hydraulic push rod to be damaged after being used for a period of time. The device can effectively increase the service life of the hydraulic push rod and reduce the working intensity of the hydraulic push rod during operation.

The device can play the role of auxiliary transmission when the workover rig is lifting heavy objects, avoiding the situation that the workover rig only operates through the hydraulic push rod in its own winch when lifting heavy objects, which may cause the hydraulic push rod to be damaged after being used for a period of time. The device can effectively increase the service life of the hydraulic push rod and reduce the working intensity of the hydraulic push rod during operation. When the workover rig is working, the cooling fan 6 is started to dissipate heat. The hot fan 6 discharges the heat generated inside it to achieve the effect of heat dissipation. The dust can be filtered through the dustproof net 12 set on the dustproof frame 11, effectively preventing too much dust from entering the built-in groove 4 of the main body. When the dustproof net 12 needs to be cleaned, the staff only needs to move the two first fixing plates 14, and the two first fixing plates 14 move away from each other.

Through the trapezoidal setting of the two trapezoidal blocks 16, the two blocking blocks 19 can be pushed into the inside of the dustproof frame groove 20. At this time, the staff can disassemble and clean the dustproof net 12. The device can effectively prevent too much dust from entering the well repairing machine, and the dustproof net 12 cannot be disassembled, and it is inconvenient to clean it when too much dust accumulates.
