Description
Technical field
The utility model relates to Machine guarding, specifically a kind of Machine guarding of hydraulically extensible mast.
Background technology
Hydraulically extensible mast is the weight-lifting equipment for the exploitation of oil well operating condition design, and in remedial work, play vital effect, be all at right angle setting operation based on hydraulically extensible mast substantially, and this just requires that mode of operation must ensure to be perfectly safe.
The hydraulic mast full state of stretching is normal working, and now the flexible spacing dependence hydraulic ram of hydraulic mast and zip ensure, once oil cylinder or zip go wrong, will likely cause serious consequence.
Utility model content
The purpose of this utility model is the Machine guarding providing a kind of hydraulically extensible mast, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of Machine guarding of hydraulically extensible mast, comprise inhibiting device, described inhibiting device comprises torsion spring and locating dowel pin, described locating dowel pin rotates with hinge and is fixedly connected with, and torsion spring is located at the junction of locating dowel pin and hinge, described hinges fixing fixes on basic arm, and described basic arm inner sleeve has telescopic boom; Described basic arm and telescopic boom are provided with the spacing hole matched with locating dowel pin; Described locating dowel pin is provided with clip.
Compared with prior art, the beneficial effects of the utility model are: the utility model is relative to existing technology, set up inhibiting device, therefore in the process used, ensure that the dual safety of mode of operation ensures, this structure operation is simultaneously convenient, simple and reliable, and cheap, therefore there are good products application scope and market outlook.
Accompanying drawing explanation
Fig. 1 is the structural representation of Machine guarding when flexible or full reduced state of a kind of hydraulically extensible mast of the utility model.
Fig. 2 be a kind of hydraulically extensible mast of the utility model Machine guarding in working order time structural representation.
In figure: 1-telescopic boom, 2-basic arm, 3-torsion spring, 4-locating dowel pin, 5-hinge, 6-spacing hole, 7-clip.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2; in the utility model embodiment; a kind of Machine guarding of hydraulically extensible mast; comprise inhibiting device; described inhibiting device comprises torsion spring 3 and locating dowel pin 4, and described locating dowel pin 4 rotates with hinge 5 and is fixedly connected with, and torsion spring 3 is located at the junction of locating dowel pin 4 and hinge 5; described hinge 5 is fixed on basic arm 2, and described basic arm 2 inner sleeve has telescopic boom 1.
Described basic arm 2 and telescopic boom 1 are provided with the spacing hole 6 matched with locating dowel pin 4.
Described locating dowel pin 4 is provided with clip 7, locating dowel pin 4 can be connected with basic arm 2 by clip 7.
Principle of work of the present utility model is: when flexible and full reduced state, is pulled out by locating dowel pin 4 artificially and fixing; (entirely stretch out state) time in working order and unclamp locating dowel pin 4, basic arm 2 is connected by spacing hole 6 with telescopic boom 1 by locating dowel pin 4 under the effect of torsion spring 3, and then ensure that the dual safety of mode of operation ensures, this structure operation is convenient, simple and reliable.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
