According to the above, in a conventional operation environment, all the multi-stage masts are used in an extending mode, and in the face of some complex operation environments and processes, for example, a working machine with pressure may be matched with other parts such as a drilling machine to perform operation, the working machine with pressure is placed in the crotch inside the drilling machine, all the masts extend to touch the crown block of the drilling machine, and at the moment, the multi-stage masts are required to be selectively extended and retracted according to actual operation requirements, for example, the 2-stage extensible masts only extend by 1 stage.

What this embodiment solved, the mast has been produced, do not need 2 hydro-cylinders single control earlier stage, the later stage is found according to the operation demand, there may be the condition that the mast stretches out and draws back alone, pass through in the aspect of hydraulic pressure this moment, carry out solitary hydraulic pressure transformation to the flexible mast of 2 grades, the work load and the cost that bring are great, so this application is on the basis of fully understanding the flexible mast principle of 2 grades or more levels, through the spacing mode of machinery, directly lock up certain one-level or multistage, thereby realize another one-level or multistage flexible, what this embodiment realized is that the one-level is flexible.

Two functions are realized through the limiting block 21, the ear plate 22, the U-shaped block 231 and the connecting piece 232:

(1) In the extending process of the mast, when the two oil cylinders extend out simultaneously, the lower section and the middle section of the mast are locked through the combination of the limiting block 21, the lug plate 22, the U-shaped block 231 and the connecting piece 232, so that the oil cylinders only run oil but cannot extend out

(2) After the upper section of the mast extends out and is well limited with the middle section, the middle section and the lower section of the mast are limited through the limiting block 21, so that the oil cylinder only participates in the extension and retraction process of the mast, and when the mast works and is loaded, the oil cylinder is not stressed, and the stability of the structure is ensured.

To the flexible mast of two hydro-cylinder drive's two-stage, even more grades, through the utility model provides a stop device and method can solve the flexible condition of the unable single control of a certain one-level of mast, can realize that the flexible mast of 2 grades only stretches out 1 level according to the demand of actual operation scene, reaches the operation requirement of co-altitude. Based on the extending principle of the mast, the situation that the mast is telescopic at 2 levels and only uses 1 level is combined with the field use requirements of customers, a limiting device and a method which enable the mast to extend out only one level are researched, and the method is also suitable for masts driven by all oil cylinders with more than 2 levels.

According to another aspect of the application, the under-pressure operation equipment with the multi-stage mast mechanism is further provided and comprises an equipment main body and the multi-stage telescopic mast mechanism.
