Description
Technical field
The utility model relates to derrick technical field of safety devices, is exactly specifically a kind of derrick hydraulic control cage ladder.
Background technology
In oil drilling and workover treatment, staff often climbs quadruple board platform from rig floor and carries out work high above the ground, now traditional derrick ladder is upright structures, staff in cat ladder process, because ladder height is higher, there is more unsafe factor, as operating personnel steps on sky accidentally, although there is safety belt, also likely injured, if safety belt goes wrong or fix insecure, easily cause casualty accident.
Summary of the invention
The purpose of this utility model is to provide a kind of derrick hydraulic control cage ladder, and structure is simple, and safety is high, and easy to operate, effectively can protect the safety of cat ladder personnel.
The technical scheme in the invention for solving the technical problem is: a kind of derrick hydraulic control cage ladder, comprise cat ladder, described cat ladder is weldingly fixed on derrick, the outside of described cat ladder is provided with cage ladder, described cage ladder is cage construction, the side of cage ladder is connected with derrick, described cage ladder comprises crossbeam and longeron, described crossbeam and longeron pass through pinned connection, described longeron is connected with derrick by bearing pin, the outermost longeron in one end of described cage ladder is connected with hydraulic means, described hydraulic means is fixedly mounted on derrick, described hydraulic means comprises hydraulic cylinder, fluid pressure line and hydraulic valve.
As optimization, described hydraulic cylinder one end is connected with longeron by bearing pin, and the other end is connected with derrick by bearing pin.
As optimization, described derrick is provided with gripper shoe, described gripper shoe is arranged on the side of the outermost longeron of cage ladder, and when cage ladder launches, gripper shoe plays a supportive role to whole cage ladder.
As optimization, described hydraulic cylinder is two, left and right, and two hydraulic cylinders connect same fluid pressure line, and are controlled together by hydraulic valve.
As optimization, described longeron is provided with Anti-slip cover, described Anti-slip cover is provided with anti-slip veins.
The beneficial effects of the utility model are: compared with prior art; a kind of derrick hydraulic control cage ladder of the present utility model; hydraulic drive is adopted to realize the collapsible expansion protecting cage; structure is simple; and easy to operate, safety is high, not with transport; conserve space, effectively can protect the safety of cat ladder personnel simultaneously.

Detailed description of the invention
As Figure 1-3 in embodiment, a kind of derrick hydraulic control cage ladder, comprise cat ladder 1, cat ladder 1 is weldingly fixed on derrick 6, the outside of cat ladder 1 is provided with cage ladder 2, cage ladder 2 is cage construction, the side of cage ladder 2 is connected with derrick 6, cage ladder 2 comprises crossbeam 7 and longeron 8, crossbeam 7 and longeron 8 are by pinned connection, and longeron 8 is connected with derrick 6 by bearing pin, and the outermost longeron 8 in one end of cage ladder 2 is connected with hydraulic means, hydraulic means is fixedly mounted on derrick 6, and hydraulic means comprises hydraulic cylinder 3, fluid pressure line 4 and hydraulic valve 5.
Hydraulic cylinder 3 one end is connected with longeron 8 by bearing pin, and the other end is connected with derrick 6 by bearing pin.
Derrick 1 is provided with gripper shoe 9, gripper shoe 9 is arranged on the side of the outermost longeron 8 of cage ladder 2, and when cage ladder 2 launches, gripper shoe 9 plays a supportive role to whole cage ladder 2.
Hydraulic cylinder 3 is two, left and right, and two hydraulic cylinders connect same fluid pressure line 4, and are controlled together by hydraulic valve 5.
Longeron 8 is provided with Anti-slip cover, Anti-slip cover is provided with anti-slip veins.
Duty: as shown in Figure 1, after derrick lifting puts in place, operation hydraulic valve, hydraulic cylinder is retracted, and protect cage and open, staff enters into quadruple board platform by protecting cage inside.
Movement state: as shown in Figure 2, operation hydraulic valve, hydraulic cylinder stretches out, and after protecting that cage is folding and putting in place, derrick is retracted on host vehicle, enters movement state.
Fig. 3 is fluid pressure line connection layout, and operating valve is linked in host vehicle hydraulic system, is coupled together between hydraulic cylinder and hydraulic valve by seamless steel pipe and high-pressure hose.
Adopt hydraulic drive to realize the collapsible expansion protecting cage, structure is simple, and easy to operate, and safety is high, and not with transport, conserve space, effectively can protect the safety of cat ladder personnel simultaneously.
Above-mentioned detailed description of the invention is only concrete case of the present utility model; scope of patent protection of the present utility model includes but not limited to product form and the style of above-mentioned detailed description of the invention; any meet the utility model claims a kind of derrick hydraulic control cage ladder and any person of an ordinary skill in the technical field to its suitable change done or modification, all should fall into scope of patent protection of the present utility model.
