Abstract

The utility model discloses a petroleum single-arm lifting ring, which comprises a first forged rod and a second forged rod, wherein annular holes are formed in the two ends of the first forged rod; an annular hole is formed in one end of the second forged rod, and the other end of the second forged rod is shaped like a fork; pin holes connected with a pin shaft at one end of the first forged rod are formed in side branches of the fork. According to the petroleum single-arm lifting ring, the other forged rod is connected to one end of a conventional lifting ring in a pin shaft connecting way, so that the single length of the conventional lifting ring is decreased, the structural shortcomings of the conventional lifting ring are improved, using requirements are met, difficulty in the machining of the lifting ring is lowered, the production cost is lowered, and resource waste is reduced.

Description

Oil single-arm hoisting ring

Technical field

The utility model relates to oil exploitation mechanical hoisting technical field, especially a kind of oil single-arm hoisting ring.

Background technology

Be accompanied by the especially high speed development of car industry of World Economics, the demand of oil and natural gas is grown with each passing day, this high dependence to oil and natural gas, makes the mining equipment of oil and natural gas have higher requirement just.

Looping pit is all with at the two ends of existing oil single-arm hoisting ring product (hereinafter to be referred as suspension ring), in order to connect the lifting means in oil producing operation, continuous upgrading along with oil exploration equipment, require traditional suspension ring more and more longer, from initial 3m, 5m develops into present 8m, 10m etc., so, the manufacture difficulty of traditional suspension ring is increased, if still made according to traditional form of structure, joint length is long, will be to forging, machine, the technology of the links such as heat treatment and process equipment require to be greatly increased, be difficult for processing simultaneously, precision is difficult to ensure card, for example need to strengthen the forging ability of forging equipment, need to improve the machining accuracy of process equipment, need to increase larger Equipment for Heating Processing, so both increased cost of manufacture, virtually also increased the scrappage of product, cause unnecessary waste to enterprise and society.

Utility model content

The utility model, for the deficiencies in the prior art, proposes a kind of oil single-arm hoisting ring, can realize different length, easy and simple to handle.

In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of oil single-arm hoisting ring, comprises that two ends, all with the first forging bar of looping pit, also comprise the second forging bar, described second one end of forging bar is looping pit, and the other end is fork-shaped; The side shoot of described fork-shaped is provided with the pin-and-hole being connected with the described first one end bearing pin that forges bar.

Further, the described second cross section that forges bar is circular.

Compared with prior art, the utlity model has following advantage: adopt bearing pin connected mode in traditional suspension ring one end, to be connected with another and forge bar, reduce the joint length of traditional suspension ring, the structure of having improved existing suspension ring is not enough, meet when using, the difficulty that reduces suspension ring processing and fabricating, has reduced production and processing cost, has reduced the wasting of resources.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the top view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.

A kind of oil single-arm hoisting ring as illustrated in fig. 1 and 2, comprises that two ends, all with the first forging bar 1 of looping

pit

11 and 12, also comprise the second forging bar 2, and described second one end of forging bar 2 is looping pit 21, and the other end is fork-shaped 22; The side shoot of described fork-shaped 22 is provided with the through hole being connected with the described first one end 11 bearing pins 3 that forge bar 1.

The utility model is when required suspension ring overall length surpasses certain limit, by novel O-U type suspension ring and traditional O-O shape suspension ring (being that two ends are looping pit 11 and 12), is linked together.O-U type suspension ring one end is looping pit 21, and one end is fork-shaped 22, is more specifically U-shaped; And O-U type suspension ring main body is the circular body of rod, on U-shaped one end, with bearing pin 3, nut 4 and cottor pin 5, bearing pin 3 is fixing by nut 4 through the pin-and-hole on U-shaped, and nut 4 is through cottor pin 5 lockings.U-shaped and bearing pin 3 forms the straight-flanked ring of a sealing, and this straight-flanked ring and traditional O-O shape suspension ring wherein one end looping pit 11 are connected to form the composite single arm petroleum hanger ring of different length.

The utility model has been changed the form of structure of suspension ring, by with being connected of traditional suspension ring, meet the requirement to length in using, and solved the difficult problem in manufacturing process.

Claims

1. an oil single-arm hoisting ring, comprises that two ends, all with the first forging bar of looping pit, is characterized in that: also comprise the second forging bar, described second one end of forging bar is looping pit, and the other end is fork-shaped; The side shoot of described fork-shaped is provided with the pin-and-hole being connected with the described first one end bearing pin that forges bar.

2. oil single-arm hoisting ring as claimed in claim 1, is characterized in that: the described second cross section that forges bar is for circular.
