Description
Technical field
This utility model relates to Current Collector Sleave technical field, the rig substructure guide pulley mechanism of a kind of anti-falling object from high altitude.
Background technology
At present, use rig to carry out Oil/gas Well when criticizing brill operation, need often mobile well location that the rig tool such as casing head, oil recovery four-way is installed.Because well location changes, and drilling well base leading block limited amount, when causing well head to lift leading block usually with well head not a vertical direction.Once misalignment angle is relatively big, will there is wire rope inclined skewing and drag, and pulley is even jumped out in the pulley outer that causes wearing and tearing, and there is pulley fragmentation and falls the risk hurted sb.'s feelings.It addition, once leading block corrosion is serious, there is also the potential risk of overall accidental falling.In well head lifting operation, either pulley fragmentation, or pulley falls, and is all likely to result in great property loss and casualties.Therefore, it is necessary to study the rig substructure guide pulley mechanism of a kind of anti-falling object from high altitude.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, it is provided that the rig substructure guide pulley mechanism of the anti-falling object from high altitude of a kind of simple in construction.
To achieve these goals, the technical solution adopted in the utility model is: the rig substructure guide pulley mechanism of a kind of anti-falling object from high altitude, it is characterized in that: include hook, turn pin buckle, support shaft, head pulley, safety rope, steel wire rope, auxiliary pulley and shell, support shaft is arranged on shell upper, hook is connected with support shaft by turning pin buckle, one end of safety rope is fixing with shell to be connected, the other end is unsettled, head pulley is arranged on shell middle and upper part, steel wire rope outlet it is provided with in the both sides, bottom of shell, each steel wire rope exit is provided with two auxiliary pulley, the spacing hole of steel wire rope is formed between two auxiliary pulley of every side, after steel wire penetrating head pulley, shell is stretched out after being each passed through corresponding spacing hole in two ends.
Further, described support shaft is articulated on shell, described in turn that one end of pin buckle is fixing with support shaft to be connected, the other end is fixed with described hook and is connected.
Further, the angle that described shell two side outlet and head pulley are formed is less than 60 degree.
Further, described safety rope is steel wire rope material, is fixedly connected with a shackle at free end.
Further, described shell integrally closed, it is internally formed the installation chamber of described head pulley and auxiliary pulley, described steel wire rope outlet auxiliary pulley installs chamber.Steel wire rope position-limiting tube it is additionally provided with in described shell.
The beneficial effects of the utility model are: simple in construction; easy to operate; by being provided with two groups of auxiliary pulley; form the spacing hole of steel wire rope, can effectively prevent steel wire rope from departing from the situation of head pulley, then by arranging safety rope; when producing; it is also secured to rig substructure with hook and fixes on hanger, it is possible to when preventing lifting, head pulley entirety is fallen situation about hurting sb.'s feelings, effective guarantee drillng operation wellhead protecting personnel and property safety.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the rig substructure guide pulley mechanism of a kind of anti-falling object from high altitude of this utility model, including linking up with 1, turning pin buckle 2, support shaft 3, head pulley 4, safety rope 5, steel wire rope 6, auxiliary pulley 7 and shell 8.Wherein, support shaft 3 is arranged on shell 8 top, and hook 1 is connected with support shaft 3 by turning pin buckle 2；One end of safety rope 5 is fixing with shell 8 to be connected, and the other end is unsettled.Head pulley 4 is arranged on the middle and upper part of shell 8, is provided with steel wire rope outlet in the both sides, bottom of shell 8, and each steel wire rope exit is provided with two auxiliary pulley 7, forms the spacing hole of steel wire rope between two auxiliary pulley 7 of every side.After steel wire rope 6 passes head pulley 4, shell 8 is stretched out after being each passed through corresponding spacing hole in two ends.
Concrete, above-mentioned support shaft 3 is articulated on shell 8, turns that one end of pin buckle 3 is fixing with support shaft 3 to be connected, the other end with link up with 1 and fix and is connected.So, owing to support shaft 3 is articulated on shell 8, rotatably, i.e. rotational pin 3 is around the axis rotation of support shaft 3.
Further, the angle that above-mentioned shell two side outlet and head pulley are formed is less than 60 degree.Above-mentioned safety rope 5 is steel wire rope material, is fixedly connected with a shackle 9 at free end.Conveniently in use safety rope hanging is fixed on hanger to rig substructure.
Above-mentioned shell 8 integrally closed, is internally formed the installation chamber of head pulley 4 and auxiliary pulley 7, and steel wire rope outlet auxiliary pulley installs chamber.In shell 8, it is additionally provided with steel wire rope position-limiting tube 10, is further ensured that steel wire rope does not shifts.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; rather than the restriction to this utility model protection domain; simple modification that the technical solution of the utility model is carried out by those of ordinary skill in the art or equivalent, all without departing from the spirit and scope of technical solutions of the utility model.
