Embodiment Construction

[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] see Figure 1-2 , a full-hydraulic low-type cover-moving machine, which includes a basic frame 8 fixed on the plane 10 of the blast furnace casthouse. The basic frame 8 is provided with a lifting mechanism 1. The lifting mechanism 1 mainly includes a lifting cylinder 4. The cover machine also includes a walking oil cylinder 2, which is installed on the walking beam 5, drives the walking beam 5 to move on the vehicle frame 3, and is provided with a hook 6 at the front end of the walking beam 5, and the ditch cover 7 is installed on the hook 6.

[0019] The oil inlet of the rodless chamber of the lifting cylinder 4 is equipped with a relief valve and a sequence valve, and the rod chamber is equipped with a relief valve to reduce back pressure and hydraulic shock, and at the same time ensure that the ditch cover stays in any position .

Abstract

The invention discloses a full-hydraulic short type cover moving machine which comprises a base framework fixed on a blast furnace casting house, wherein a lifting mechanism is arranged on the base framework; the lifting mechanism mainly comprises a lifting oil cylinder; the cover moving machine further comprises a travelling oil cylinder which is fixed on a travelling beam for driving the travelling beam to move on a frame; a hanger is arranged at the front end of the traveling beam; a channel cover is arranged on the hanger. The full-hydraulic short type cover moving machine disclosed by the invention is simple, efficient, safe and environment-friendly channel cover moving equipment, and is lifted (or descended) by the lifting oil cylinder arranged on the lifting mechanism, so that the lifting (or descending) of the frame, the travelling beam, the hanger and the channel cover is realized; reciprocating translation of the travelling beam, the hanger and the channel cover is realized by stretching-out and drawing-back of the travelling oil cylinder arranged on the travelling beam.

Description

technical field [0001] The invention relates to a front equipment of an ironmaking blast furnace, in particular to a fully hydraulic low type cover moving machine. Background technique [0002] With the development of short and fat iron-making blast furnaces, the space between the tuyere platform and the casthouse platform is reduced. In order to meet the requirements of environmental protection and improve the working environment in front of the blast furnace, reduce heat radiation and reduce heat radiation. In order to prevent the damage of guns and other equipment, we developed and invented a fully hydraulic low-type cover-moving machine. It should be noted that due to the restriction of the tuyere platform, the crane cannot enter this area for operation. Contents of the invention [0003] The object of the present invention is to provide a fully hydraulic short cover moving machine, which is a simple, efficient, safe and environmentally friendly ditch cover moving dev...
