Abstract
A kind of turning walking on stage, it is characterized in that: it comprises the holder (3) combining with relevant device by connector, walk on stage (1) combining with holder (3) by articulated manner, and the one end and the holder (3) that are positioned at (1) below of walking on stage are hinged, the other end is arranged on support bar (2) that process and the chute plane parallel of walking on stage on walk on stage (1) by guide and limit pin; Described chute is provided with backing pin groove near holder one end.The utility model is by the local optimum of structure, a difficult problem for limit for width while having solved equipment conveying, and reliability is high, easy to use, a kind of rational in infrastructure, easy to install, economical and practical device of can yet be regarded as.
Description
Technical field
The utility model relates to the association area such as engineering machinery, handling machinery that needs installation and repairing to walk on stage.
Background technology
Existing engineering machinery and the maintenance of handling machinery product are walked on stage, and mostly employing is not turnover fixedly walks on stage, and the requirement due to highway limit for width in the time of equipment conveying need to be by the dismounting of walking on stage, and dismantles frequently and installs to construction and brought unnecessary trouble.
Summary of the invention
The one that the purpose of this utility model provides for above-mentioned the deficiencies in the prior art is just simple in structure, easy to use, saves turning the walking on stage of human and material resources cost.
The purpose of this utility model can realize by following technique measures:
Turning walking on stage of the present utility model comprises the holder combining with relevant device by connector, what combine with holder by articulated manner walks on stage, and be positioned at walk on stage below one end and holder be hinged, the other end by guide and limit pin be arranged on walk on stage on support bar that process and the chute plane parallel of walking on stage; Described chute is provided with backing pin groove near holder one end.
Angle between the axis of backing pin groove described in the utility model and chute axis is less than 90o.
Operating principle of the present utility model is as follows:
During when equipment conveying or in off working state, can be by vertical the placement with saving space of walking on stage, concrete steps are as follows: while being turned to upright position when walking on stage to side top, support bar falls into backing pin groove with the guide and limit pin of the binding end of walking on stage along chute, make to walk on stage in vertical laying state, for preventing the vibration landing of walking on stage, backing pin groove, with certain gradient (hook type structure), can prevent the vibrations landing of walking on stage under the effect of walking on stage in the time walking on stage vertical placement transport deadweight and backing pin groove.Equipment work only need skid off the guide and limit pin of support bar just and can set level walking on stage time from backing pin groove, walks on stage while keeping flat, to form stable triangle beaer and can bear enough external force, for maintainer provides reliable maintenance platform.
The beneficial effects of the utility model are as follows:
The utility model is by the local optimum of structure, a difficult problem for limit for width while having solved equipment conveying, and reliability is high, easy to use, a kind of rational in infrastructure, easy to install, economical and practical device of can yet be regarded as.

Detailed description of the invention
As shown in Figure 1, 2, 3, turning walking on stage of the present utility model comprises the holder 3 combining with relevant device by connector, what combine with holder 3 in hinged way by bearing pin 4 walks on stage 1, and the one end and the holder 3 that are positioned at 1 below of walking on stage are hinged, the other end is arranged on by guide and limit pin the support bar 2 that process and the chute plane parallel of walking on stage on 1 of walking on stage; Described chute is provided with backing pin groove near holder one end, and described backing pin groove is hook type structure, and the angle between the axis of backing pin groove and chute axis is less than 90o.
As shown in Figure 4, the concrete using method of the utility model on rotary drilling rig is as follows:
First need threaded block to be welded on the left and right backplate of rotary drilling rig platform, then with bolt, the turning holder of walking on stage 3 is fixed on threaded block.
Claims (2)
