Abstract
The utility model discloses a foldable type top-driving guide rail which comprises a plurality of sections of guide rail units. Hinge portions used for movable connection are arranged at the head ends and the tail ends, which are connected, of two adjacent guide rail units, and a serial connection tightening rope is arranged in inner cavities of the first section of guide rail unit to the last section of guide rail unit. When the tightening rope is tensioned, all sections of guide rail units can rotate through the hinge portions to be spliced to form a whole structure of the top-driving guide rail. The foldable type top-driving guide rail is simple in structure, saves a lot of work hours in an installing and dismounting process, avoids repeatedly dismounting and installing guide rail connection pins and prevents unnecessary damage.
Description
Technical field
The utility model relates to a kind of folded form top drive guide rail.
Background technology
As shown in Figure 1 and Figure 2, adopt pin to connect between the existing top drive guide rail, two joint guide rails fix it with two connecting pins, each dismounting all will be repeatedly the plug pin, influence mounts and dismounts man-hour, and the guide rail that disassembles is laid scattered not manageability, and the long-term guide pins bore deformation that uses is serious, and operation impacts to guide rail.This class guide rail does not have rational protection mechanism yet, when meeting burst accident by chance, if the guide rail fatigue failure, fracture suddenly, the top drive guide rail that drops will smash rig, and cause casualties, and safety is not high.
The utility model content
At the problem that prior art exists, the purpose of this utility model be to provide a kind of simple in structure, mount and dismount folded form top drive guide rail easily.
For achieving the above object, the utility model folded form top drive guide rail, comprise some joint rail units, the initial and end of adjacent two joint rail units joins to holding to be provided with and is used for the articulated section of flexible connection mutually, be provided with serial connection in the internal cavities of rail unit and collapse rope from first segment to final section, strain this and collapse rope, each saves rail unit and rotates by described articulated section, is spliced to form the top drive guide rail overall structure mutually.
Further, described articulated section adopts single pins to connect.
Further, being provided with bottom of described top drive guide rail is used to strain the described hydraulic power supply that collapses rope.
Further, the folding back of described some joint rail units forms whole harvesting structure, and this harvesting structure is equipped with the guide rail pallet that is used for its whole delivery.
The utility model is simple in structure, has saved a large amount of man-hours in the installation and removal process, and the guide rail connecting pin has been avoided the unnecessary damage of guide rail without repeated disassembled and assembled.

The specific embodiment
Below, with reference to the accompanying drawings, the utility model is more fully illustrated, exemplary embodiment of the present utility model has been shown in the accompanying drawing.Yet the utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make the utility model, and scope of the present utility model is fully conveyed to those of ordinary skill in the art comprehensively with complete.
In order to be easy to explanation, here can use such as " on ", D score " left side " space relative terms such as " right sides ", be used for element shown in the key diagram or feature relation with respect to another element or feature.It should be understood that except the orientation shown in the figure spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device among the figure is squeezed, be stated as the element that is positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (revolve turn 90 degrees or be positioned at other orientation), and the relative explanation in used here space can correspondingly be explained.
To shown in Figure 6, the utility model folded form top drive guide rail comprises some joint rail units 1 as Fig. 3, and the initial and end of adjacent two joint rail units 1 joins to holding to be provided with and is used for the articulated section 2 of flexible connection mutually, and articulated section 2 adopts single pins 3 to connect.Be provided with serial connection in the internal cavities of rail unit and collapse the rope (not shown) from first segment to final section, being provided with bottom of top drive guide rail is used to strain the hydraulic power supply that collapses rope, strain this and collapse rope, each saves rail unit and rotates by described articulated section 2, is spliced to form the top drive guide rail overall structure mutually.The folding back of some joint rail units forms whole harvesting structure, and this harvesting structure is equipped with the guide rail pallet that is used for its whole delivery.
The utility model top drive guide rail with designed in the past different, difference to some extent on the connecting pin pore structure at the head of every joint guide rail, last two ends, this can realize alternate folding between the guide rail, can satisfy the requirement that respectively saves the guide rail integral lifting, in the installation and removal process, saved a large amount of man-hours, and the guide rail connecting pin has been avoided the unnecessary damage of guide rail without repeated disassembled and assembled.
Drive not for guide rail is equipped with special-purpose storing unit on the tradition top, and for this reason, the also special supporting guide rail pallet (not shown) that designed is driven on this top, is convenient to like this in the removal of home process the whole delivery of top drive guide rail.Because adopt between this guide rail single pins to connect, this does not fully limit its degree of freedom, so need can strain the rope that collapses that is positioned at hollow guide rail inside, tighten all guide rails at guide rail equipment hydraulic power supply bottom, it is fixed.Because to collapse rope firmer relatively, thus this connected mode than traditional pin connection reliability height, a whole set of guide rail flexibility is less.The most important thing is to collapse the effect that rope has played safety rope, it comes off in the time of can preventing the fracture of guide rail accident immediately, and drive on other models tops relatively, and more outstanding safety is driven on the utility model top.
