Abstract

The utility model discloses a portable oil drilling cat ladder relates to the oilfield equipment field, and the equidistance is equipped with a plurality of horizontal poles between this portable oil drilling cat ladder's the side rod, and the equal symmetry of tow sides at side rod both ends is equipped with 16 couples, and the couple is three ring shapes of quartering, and the couple bill at side rod both ends sets up relatively. Can manually will get in touch on drilling platform's crossbeam during the use, scramble the horizontal pole of cat ladder again and since drilling platform a bit crossbeam be the slope design, the event is adopted and manyly can be adjusted the angle that hangs of cat ladder to the couple, makes the climbing easier, when waiting to climb to the cat ladder top, more height is upwards caught on with the cat ladder again in the position of can having stood, continues the climbing, is fit for the drilling platform of climbing height difference.

Description

Portable petroleum drilling cat ladder

Technical field

The utility model relates to oil field equipment field, in particular to the portable petroleum drilling cat ladder of one.

Background technology

Modern petroleum exploitation adopts mechanical means to carry out mostly, builds oil drilling platform, installs oil-well rig, drives drilling tool breaking up rock, creep into underground, bore out the well of prescribed depth, obtains oil or Sweet natural gas for oil production machine or gas production machine.

The drilling unit of great majority is all provided with cat ladder at present, but is often only arranged on one or two, and the damage of drilling unit is comprehensive, and the place that some cat ladder cannot touch often is difficult to maintenance, and common ladder is not suitable for using on drilling unit.

Practical novel content

Technical problem to be solved in the utility model is to provide a kind of portable petroleum drilling cat ladder, is equipped with some hooks on the two sides at ladder two, and hook, in 3/4ths toroidals, uses in the steel framework structure of drilling unit to adapt to.

For achieving the above object, the utility model provides following technical scheme: a kind of portable petroleum drilling cat ladder, it is characterized in that: described portable petroleum drilling cat ladder comprises two parallel cylindrical limit bars, the diameter of both sides bar and identical length etc., equidistant between the bar of limit it is provided with some cross bars, cross bar size is equal, and cross bar is all perpendicular to both sides bar, the tow sides at bar two ends, limit are all arranged with 16 hooks, hook is 3/4ths toroidals, and the hook bill at bar two ends, limit is oppositely arranged.

Preferably, described limit bar, cross bar, hook is by aluminium alloy manufacture.

Preferably, described cross bar and hook are all fixedly connected by welding on the bar of limit.

Preferably, described hook is two one rows, four column-shaped distributions on the bar of limit.

The useful effect of above technical scheme is adopted to be: equidistant between the limit bar of this portable petroleum drilling cat ladder to be provided with some cross bars, the tow sides at bar two ends, limit are all arranged with 16 hooks, hook is 3/4ths toroidals, and the hook bill at bar two ends, limit is oppositely arranged. Can manually extension be hooked on the crossbeam of drilling unit during use, climb the cross bar of cat ladder again, owing to some crossbeam of drilling unit is inclined design, therefore adopt multipair hook can adjust the suspension angles of cat ladder, climbing is more prone to, in time climbing to cat ladder top, can stand good position, cat ladder is upwards caught on more higher position again, continues climbing, be applicable to the drilling unit that climbing height is different.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

Fig. 1 is the front view of a kind of portable petroleum drilling cat ladder of the utility model;

Fig. 2 is the vertical view of a kind of portable petroleum drilling cat ladder of the utility model.

Wherein, 1-limit bar, 2-cross bar, 3-link up with.

Embodiment

The preferred implementation of a kind of portable petroleum drilling cat ladder of the utility model is described in detail below in conjunction with accompanying drawing.

Fig. 1 with Fig. 2 shows the embodiment of a kind of portable petroleum drilling cat ladder of the utility model: this portable petroleum drilling cat ladder comprises two parallel cylindrical limit bars 1, the diameter of both sides bar 1 and identical length etc., equidistant between limit bar 1 it is provided with some cross bars 2, cross bar 2 size is equal, and cross bar 2 is all perpendicular to both sides bar 1, the tow sides at limit bar 1 two ends are all arranged with 16 hooks 3, hook 3 is in 3/4ths toroidals, catch on difficult drop-off after the crossbeam of drilling unit, ensure the life safety of serviceman, and hook 3 bill at limit bar 1 two ends is oppositely arranged.

Composition graphs 1 and Fig. 2, limit bar 1, cross bar 2, hook 3 are by aluminium alloy manufacture, and firm in structure, security is good, and material is relatively light, easy to carry and use. Cross bar 2 and hook 3 are all fixedly connected by welding on limit bar 1, are welded to connect firm, not easily fall apart, and security is good, and manufacture simple, with low cost. Described hook 3 is two one rows, four column-shaped distributions on limit bar 1, and linking up with 3 one end is two row's structures, is suitable for catching on the drilling unit crossbeam of inclined design, ensures that cat ladder is vertical setting, grasps balancing when being conducive to serviceman to climb.

Manually hook 3 can be hung on the crossbeam of drilling unit during use, climb the cross bar 2 of cat ladder again, owing to some crossbeam of drilling unit is inclined design, therefore adopt multipair hook 3 can adjust the suspension angles of cat ladder, climbing is more prone to, in time climbing to cat ladder top, can stand good position, then the hook 3 of cat ladder is upwards caught on more higher position, continue climbing, this cat ladder is applicable to climbing the different drilling unit of height, is widely used.

Above is only preferred implementation of the present utility model; it is noted that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also making some distortion and improvement, these all belong to protection domain of the present utility model.
