Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned existing magnetic hoisting problem that often occurs when hoisting, and to design a hoisting device specially used for hoisting oil pipelines. The hoisting device uses an anti-reverse mechanism to prevent the hoisting Slippage occurs, and the safety frame can be used to limit the rotation, which solves the problem of slippage that often occurs when the existing magnetic hoist is hoisted

Embodiment 1

[0012] Such as figure 1 As shown, the hoisting device specially used for hoisting oil pipelines includes a mounting base 1, a magnetic system 16 and a transmission mechanism are arranged under the mounting base 1, the magnetic system 16 is connected to the transmission mechanism, and a hanging plate is provided on the top of the mounting base 1 8. The number of hanging plates 8 is two, and there are hanging rings 9 between the two hanging plates 8, and the hanging rings 9 are connected with the two hanging plates 8 at the same time; two brackets 17 are arranged on the mounting base 1, and the hanging plates 8 are far away from the One end of the suspension ring 9 is respectively connected with one of the brackets 17, and the suspension plate 8 is provided with a pawl 6, the pawl 6 is connected with a ratchet 5, the ratchet 5 is connected with an anti-reversal pawl 2, and the ratchet 5 is arranged on the pawl 6 and Between the anti-reverse pawls 2, the anti-reverse pawls 2 are ...

Embodiment 2

[0014] Such as figure 1 As shown, an anti-reverse pawl spring 3 is sleeved on the outer wall of the anti-reverse pawl shaft 18, and the anti-reverse pawl spring 3 is respectively arranged at both ends of the anti-reverse pawl 2, and the anti-reverse pawl spring 3 corresponds to contact with the anti-reverse pawl 2 and the bracket 17. On ratchet 6, be provided with ratchet spring 7, this is existing structure. The transmission mechanism includes a driving sprocket 10 and a driven sprocket 12, the driving sprocket 10 and the driven sprocket 12 are correspondingly arranged at both ends of the mounting base 1, the driving sprocket 10 is arranged above the mounting base 1, and one end of the ratchet shaft passes through After the ratchet 5 is connected with the corresponding driving sprocket 10, a chain one 11 is arranged between the driving sprocket 10 and the driven sprocket 12, and the chain one 11 is fitted on the driving sprocket 10 and the driven sprocket 12 at the same time...

Abstract

The invention discloses a special lifting device for lifting a petroleum pipeline. A magnetic system and a transmission mechanism are arranged below a mounting base; the magnetic system is connected with the transmission mechanism; two brackets are arranged on the mounting base; one end, far away from a lifting ring, of a lifting plate is connected with one of the two brackets; a pawl is arranged in the lifting plate; a ratchet wheel is connected to the pawl; an anti-reverse pawl is connected to the ratchet wheel; the ratchet wheel is arranged between the pawl and the anti-reverse pawl; an anti-reverse pawl shaft is arranged in the anti-reverse pawl; two ends of the anti-reverse pawl shaft are arranged in the corresponding brackets after passing through the anti-reverse pawl; a ratchet wheel shaft is arranged in the ratchet wheel; one end of the ratchet wheel shaft is connected with the corresponding transmission mechanism after passing through the ratchet wheel; and an insurance frame is arranged on the mounting base, fixed on the mounting base and arranged below the lifting plate. An anti-reverse mechanism is adopted to prevent the lifting device from slipping, and the problem of frequent slipping generated when an existing magnetic lifting device is used for lifting is solved.

Description

technical field [0001] The invention relates to a mechanical structure, in particular to a hoisting device specially used for hoisting oil pipelines, which belongs to the field of petroleum machinery. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. It is composed of a mixture of different hydrocarbons, and its main component is alkanes. In addition, petroleum also contains elements such as sulfur, oxygen, nitrogen, phosphorus, and vanadium. Petroleum is mainly used as fuel oil and gasoline, which constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. Oil is mostly hydrocarbons. It is composed of a mixture of different hydrocarbons. The chemical elements that make up petroleum are mainly carbon (83% ~ 87%), ...
