Description

A kind of adjustable rig floor cat ladder
Technical field
The utility model is related to oil equipment field, is specifically exactly that one kind can be according to inclined shaft workover rig derrick angle The rig floor cat ladder being adjusted.
Background technology
With the development of petroleum equipment industry, oil equipment also becomes more diverse, slant rig, workover rig also meet the tendency of and It is raw.The derrick of inclined shaft workover rig can realize the angle work between 45 °~90 °, and rig floor can be moved with the rotation of derrick It is dynamic,
Existing rig floor ladder can only be used in fixed angles and positions, and the different angle needs that adapt to derrick are a variety of Ladder, can cause waste with it is inconvenient for use, it is therefore desirable to a kind of adjustable-angle cat ladder, cooperation rig floor use.
The content of the invention
The purpose of this utility model is a kind of adjustable rig floor cat ladder of offer, and the cat ladder passes through universal rotating shaft and roller knot The design of structure, realizes synchronous axial system when rig floor is rotated with workover rig derrick, can ensure ladder under rig floor any angle In applicable position.
The technical scheme in the invention for solving the technical problem is:
A kind of adjustable rig floor cat ladder, including ladder body, universal drive shaft group and afterbody roller, described ladder body include Dismountable link is provided with the top of ladder, sole and guardrail, described ladder, described universal drive shaft group includes connecting with rig floor The connecting device for ladder stand that the rig floor attachment means connect are connected with cat ladder, described connecting device for ladder stand is connected by link and ladder It is connected together, described afterbody roller is arranged on the afterbody of ladder, including roller and rolling wheel support.
As optimization, described rig floor attachment means include rig floor link and ectosphere, and described rig floor link passes through It is bolted on the support of rig floor.
As optimization, described rig floor link and ectosphere are one of the forming.
As optimization, described rig floor link both sides are respectively arranged with safety rope and install the stay hook of safety rope.
As optimization, described connecting device for ladder stand includes cat ladder link and interior ball, described cat ladder link bottom On link.
As optimization, the cat ladder link and interior ball are one of the forming.
As optimization, described interior ball is used cooperatively with ectosphere, and interior ball rotates in ectosphere.
As optimization, described cat ladder link both sides are respectively arranged with stay hook, for fixing safety rope.
The beneficial effects of the utility model are:Compared with prior art, a kind of adjustable rig floor cat ladder of the present utility model, Substitution can only fix the ladder used at present, when rig floor carries out angular transformation with derrick, between adjustable rig floor cat ladder and rig floor It is always maintained at reasonably using angle, it is easy to use without changing ladder.

Fig. 2 is the utility model left view(Universal drive shaft is omitted);
Fig. 3 is the utility model afterbody roller enlarged diagram;
Fig. 4 is the utility model universal drive shaft group enlarged diagram
Wherein, 1 ladder body, 2 universal drive shaft groups, 21 rig floor links, 22 ectospheres, ball, 24 cat ladder links, 25 peaces in 23 Quan Sheng, stay hook, 27 times stay hooks, 3 afterbody rollers, 4 links on 26.
Embodiment
A kind of adjustable rig floor cat ladder, including ladder body 1, universal drive shaft group 2 and afterbody roller 3, described ladder body 1 Including ladder, sole and guardrail, dismountable link 4 is provided with the top of described ladder, described link 4 passes through bolt It is fastened on ladder, described universal drive shaft group 2 includes the cat ladder that rig floor attachment means are connected with cat ladder being connected with rig floor Attachment means, described connecting device for ladder stand is linked together by link 4 with ladder body, and described afterbody roller 3 is pacified Mounted in the afterbody of ladder body 1, described afterbody roller 3 includes roller and rolling wheel support.
Rig floor attachment means include rig floor link 21 and ectosphere 22, and rig floor link 21 is bolted on rig floor On support;Rig floor link 21 and ectosphere 22 can be integrally formed;The both sides of rig floor link 21 are respectively arranged with safety rope 25 and install safety rope upper stay hook 26.
Connecting device for ladder stand includes cat ladder link 24 and interior ball 23, and the bottom of cat ladder link 23 is arranged on link 4; Cat ladder link 24 and interior ball 23 are one of the forming;Interior ball 23 is used cooperatively with ectosphere 22, and interior ball 23 is in the inside of ectosphere 22, Interior ball 23 is freely rotatable in ectosphere 22.
In the present embodiment, when the run-off the straight in use of the derrick of inclined shaft workover rig, rig floor follows derrick Angle is moved, and now the roller of rig floor ladder base is rolled, and by the adjustment effect of universal drive shaft group at the top of rig floor cat ladder, makes ladder The angle of reasonable employment is always maintained between main rig floor.
The both sides of rig floor link 21 are respectively arranged with safety rope 25 and install the upper stay hook 26 of safety rope;Cat ladder link 24 both sides are respectively arranged with lower stay hook 27, safe during in order to ensure using, and are being adjusted and during other operations, can pass through Safety rope 25 links together upper stay hook 26 with lower stay hook 27, it is ensured that the secure connection of adjustable cat ladder and rig floor.
Above-mentioned embodiment is only specific case of the present utility model, and scope of patent protection of the present utility model includes But the product form and style of above-mentioned embodiment are not limited to, it is any to meet the adjustable of the utility model claims Appropriate change or modification that rig floor cat ladder and any person of an ordinary skill in the technical field are done to it, should all fall into this reality With new scope of patent protection.
