The utility model discloses simple structure, the cost of manufacture is low, foldable back and the whole transportation of rig inclined ladder during the relocation, and the installation is swift convenient, sparingly moves the fortune cost.
Description
Technical field
The utility model relates to the syndeton of a kind of inclined ladder and railing, particularly relates to the collapsible railing of a kind of rig inclined ladder.
Background technology
Along with oil drill equipment develops rapidly, the movement and movement cost of rig require more and more higher, need drill rig components to carry out rational modularization like this.For rig inclined ladder railing, be folded on paving platform and transport together, not only can reduce cost of transportation, also reduce the set-up time again simultaneously, save aided drilling cost.
The railing of traditional structure forms is using and there is following shortcoming in transporting: 1) when moving transport, and railing will carry out dismounting with ladder to be separated and transport, increase back work amount, and indirectly adds drilling cost; 2) in transportation, railing post is collided and can deforms, and causes installing difficulty and even can not normally use; 3) traditional plug-in railing will be embedded on inclined ladder girder guardrail base, so not only can injure mother metal, and there is dead angle and be difficult to carry out preservative treatment.
Summary of the invention
The utility model provides the collapsible railing of a kind of rig inclined ladder, and its structure is simple, and cost of manufacture is low, and collapsible rear and rig inclined ladder whole Transporting during resettlement, and convenience quick for installation, save movement cost.
In order to achieve the above object, the utility model realizes by the following technical solutions:
The collapsible railing of a kind of rig inclined ladder, be arranged on rig inclined ladder both sides, railing body is made up of column and cross bar; Described column is connected with rig inclined ladder with bearing pin by fixed ear base, and fixed ear base is fixed on outside rig inclined ladder, and it is axially arranged with 2 connecting holes along column, and 2 bearing pins are each passed through connecting hole and are fixedly connected with column; Bearing pin and rig inclined ladder longitudinal axis parallel are arranged, and installation site is higher than rig inclined ladder upper surface; 2 bearing pin heads are respectively with safety pin locking, and afterbody is connected by short chain; The length of column is not more than rig inclined ladder width.
Described fixed ear base is made up of L shape otic placode and baffle plate, and 2 L shape otic placodes be arranged in parallel, and base overhanging end is connected by baffle plate and is fixed on rig inclined ladder girder; Spacing and the column external diameter of 2 L shape otic placodes adapt.
Compared with prior art, the beneficial effects of the utility model are:
Structure is simple, and cost of manufacture is low, and collapsible rear and rig inclined ladder whole Transporting during resettlement, and convenience quick for installation, save movement cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Seeing Fig. 1, is structural representation of the present utility model, the collapsible railing of a kind of rig inclined ladder of the utility model, and be arranged on rig inclined ladder 1 both sides, railing body 2 is made up of column 21 and cross bar 22; Described column 21 is connected with rig inclined ladder 1 with bearing pin 5 by fixed ear base 4, and fixed ear base 4 is fixed on outside rig inclined ladder 1, and it is axially arranged with 2 connecting holes along column 21, and 2 bearing pins 5 are each passed through connecting hole and are fixedly connected with column 21; Bearing pin 5 and rig inclined ladder 1 longitudinal axis parallel are arranged, and installation site is higher than rig inclined ladder 1 upper surface; 2 bearing pin 5 heads are locked with safety pin 6 respectively, and afterbody is connected by short chain 3; The length of column 21 is not more than rig inclined ladder 1 width.
Described fixed ear base 4 is made up of (as shown in Figure 3) L shape otic placode 41 and baffle plate 42, and 2 L shape otic placodes 41 be arranged in parallel, and base overhanging end is connected by baffle plate 42 and is fixed on rig inclined ladder 1 girder; Spacing and column 21 external diameter of 2 L shape otic placodes 41 adapt.
Also two connecting holes are provided with bottom column 21, corresponding with the connecting hole on fixed ear base 4 respectively, by bearing pin 5, fixed ear base 4 is connected with column 21; Bearing pin 5 head adopts safety pin 6 to fix respectively, and the afterbody of 2 bearing pins 5 welds with the two ends of short chain 3 respectively, is connected as a single entity.Fixed ear base 4 integral solder is in rig inclined ladder 1 girder channel-section steel both sides.
As shown in Figure 2, during movement, first unloaded by the bearing pin 5 on side fixed ear base 4 top, make to only have a bearing pin 5 to fix between column 21 and fixed ear base 4, now, railing body 2 can be flattened on rig inclined ladder 1 after rig inclined ladder 1 folded inside turn to level; Then the bearing pin 5 of opposite side fixed ear base 4 bottom is all unloaded, same inwardly folded turnover, on the opposite side railing body 2 making it be flattened on to have folded; After folding, overall structure is very compact, saves transport space.2 bearing pins 5 are linked together by short chain 3, and one of them also can not be lost after unloading.When movement puts in place and reinstalls, only the bearing pin 5 unloaded need be reinstalled and put in place, very convenient, save the set-up time.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
