Abstract

Disclosed is an oil pumping unit horse-head pin extractor, which is a dismounting apparatus on an oil pumping unit in the oil field overcoming the defects of the current technique, and the dismounting apparatus is connected by a fastening bolt, a fixed mount, an impact hammer, a piston rod, a connecting bolt, an impact cylinder, an upper clamping plate and a lower clamping plate, wherein the impact hammer is fixed on a piston rod of the impact cylinder, the fixed mount is fixed on the impact cylinder by the connecting bolt, the upper clamping plate and the lower clamping plate are arranged on the fixed mount, and the fastening bolt is disposed on the upper clamping plate; when in operation, the pin can be packed out by only placing the extractor at a specified position and operating a hand-operated valve easily by a worker; and the apparatus greatly reduces the labor intensity, improves the work efficiency and guarantees the safety of operation staff.

Description

The horse head pin of pumping unit extractor

One, technical field:

The utility model relates to the dismounting utensil on a kind of oil-field oil pumper, especially horse head pin of pumping unit extractor.

Two, background technology:

In the maintenance process of the operation of oil well and oil pumper, wanting frequent dismounting horse head pin, all is at present to take the way of pounding with iron hammer, and not only labour intensity is big for this artificial method, and efficient is extremely low, sometimes pin that gets rusty, all pound to come out half a day, seriously influenced manufacturing schedule, in addition owing to be work high above the ground, do not base oneself upon part on the oil pumper again, this way is inconvenience very, and exist very big potential safety hazard.

Three, summary of the invention:

That the purpose of this utility model provides is easy and simple to handle, the horse head pin of pumping unit extractor of high efficiency, it has solved the shortcoming that present technology exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by fastening bolt, fixed mount, jump bit, piston rod, connecting bolt, impact cylinder, train wheel bridge and lower plate, jump bit is fixed on the piston rod that impacts cylinder, fixed mount is fixed on by connecting bolt and impacts on the cylinder, train wheel bridge and lower plate are arranged on fixed mount, fastening bolt is arranged on the train wheel bridge.

During work, the horse head pin extractor is hung the height of horse head pin by the lifting means at scene, on the pedestal that the support bracket fastened train wheel bridge and the lower plate of horse head pin extractor is stuck in horse head pin, the top and bottom of pin are slipped into respectively in the open slot of train wheel bridge and lower plate, tighten fastening bolt then, whole extractor is securely fixed on the oil pumper, and make the piston rod that impacts cylinder and horse head pin on a center line, connect source of the gas then, the operation pneumatic operated valve, impact cylinder and will drive jump bit, make pin loosening until being ejected with strong wallop and suitable frequency impact horse head pin.

Use this device greatly to reduce labour intensity, improved operating efficiency, ensured operating personnel's safety.
