Problems solved by technology

[0003] During the long-term operation of the pumping unit, various parts will wear out, especially after the top parts of the pumping unit are damaged, the staff often need to climb up and down on the support to carry out the work, but at present, the pumping unit is equipped with The structure of the ladder is relatively simple, and it is only composed of simple welding of steel bars. It is difficult to ensure the safety of the staff during climbing operations, making climbing the ladder on the bracket a dangerous job, and it may fall if you are not careful. Due to the height of the pumping derrick Large, falling from the ladder will cause very serious consequences, even endangering the lives of staff

Embodiment Construction

[0024] In order to make the technical means, creative features, purpose and effect of this device easy to understand, a detailed description will be given below in conjunction with specific illustrations.

[0025] Such as figure 1 As shown, the cage ladder involved in an embodiment of the present invention includes a bracket 1, a ladder 2 and a protective cover 3. The ladder 2 is fixed by the bracket 1 and is used for climbing by maintenance personnel. The protective cover 3 is buckled and installed on the side of the climbing surface of the ladder 2 to form a crawling channel to protect the operator.

[0026] In this embodiment, through the above structure, the cage ladder can be completely independent and can be installed wherever needed. During installation, the bracket 1 and / or the protective cover 3 can form a fixed relationship with the fixed point, so that the cage ladder is in use It’s safer. The protective cover can provide a stop or support point for the user, and can pr...

Abstract

The invention relates to a cage ladder, comprising a ladder for climbing; a support connected with a fixing point for fixing the ladder; a protective cover mounted on one side of a climbing face of the ladder in a fastened manner and forming on the climbing face of the ladder a passage for a user to climb up and down. The defects of the prior art are overcome, the cage ladder is reasonable in structural design, easy to manufacture, accurate to connect and position, safe and highly reliable, and convenient to use; a maintainer can climb the ladder within the protective cover without the concern for falling danger, thus having improved safety coefficient.

Description

Technical field [0001] The invention relates to the field of petroleum exploitation, in particular to a cage ladder for pumping units. Background technique [0002] There are two types of oil extraction methods in oilfields. One is to use the natural pressure of the oilfield to lift crude oil, which is commonly referred to as self-spray oil extraction; the other is that the natural pressure is insufficient and rely on artificial supplementary pressure to lift the crude oil to the ground, which is commonly referred to as artificial lift. , The pumping unit oil extraction method accounts for 90% of the number of artificial lift wells, which shows that the pumping unit oil extraction method is currently the most important oil extraction method. [0003] During the long-term operation of the pumping unit, various parts will wear out, especially after the parts on the top of the pumping unit are damaged, the staff often need to climb up and down the support for work, but at present, the...
