Abstract
The utility model relates to a dual-pneumatic locked derrick. A derrick upper-middle body cylinder locking device and a derrick middle-lower body cylinder locking device are mounted on the bearing breams on the inner side and the outer side of the derrick respectively; two sets of rotary and support type locking devices are respectively opened in the sequential stretching out and drawing back process of the upper-middle body of a three-section sleeved derrick, and the function of locking the derrick is achieved. The dual-pneumatic locked derrick is compact in structure, sensitive, reliable, easy to observe and safe to operate.
Description
Technical field
The utility model relates to the application of petroleum drilling and mining derrick locking, i.e. two pneuma-lock derricks.
Background technology
The at present locking of suit derrick configures a set of pneumatic locking device and a set of mechanical type locking device that asks.The mechanical type locking device structure complexity that asks, needs configuration locking crossbeam, connects the connecting rod that asks both sides, structural member, particularly derrick are flexible needs manually to climb after putting in place and to high-altitude, assign the safety pin that asks for coil tension spring etc., have potential safety hazard.
Utility model content
The utility model object is the deficiency that solves above-mentioned locking device, and a kind of compact overall structure, the two pneuma-lock derricks of sensitive derrick reliable, that be easy to observation, handling safety are now provided.
Technical solution of the present utility model is: two pneuma-lock derricks be on the derrick of three joints suits, the carrier bar place of middle body inner side installed on locking derrick, the cover cylinder locking device A of two between middle body and in derrick, the carrier bar place in lower body outside installed in locking derrick, the cover of two between lower body cylinder locking device B.
Cylinder locking device A comprises that dihedral asks, and ask one end and derrick upper body spandrel girder are articulated and connected, and is connected with cylinder piston end simultaneously, and the cylinder other end is connected with derrick upper body.
Cylinder locking device B comprises that dihedral asks, and ask one end and derrick lower body spandrel girder are articulated and connected, and is connected with cylinder piston end simultaneously, and the cylinder other end is connected with derrick lower body.
On the derrick of three joint suits, middle body opens respectively the formula locking device that asks that upper and lower two cover double-acting cylinders are controlled in telescopic process successively, realizes derrick locking function.
Advantage of the present utility model: 1, two pneuma-lock derrick geometries are compact, and integral body takes up room little.2, the rotation of asking that cylinder is controlled is highly sensitive.3, be arranged on joint outside under inner side, derrick upper body and derrick, guarantee the flexible and locking smoothly of three joint suit derricks.4, ask and locate to be furnished with circular arc limited block, security performance is high.

The specific embodiment
Referring to Fig. 1-5, component title is as follows: limited block 1, ask 2, and riser 3, pivot pin 4, cylinder 5, support plate 6, derrick upper body 7, in derrick, body 8, derrick lower body 9, cylinder locking device A, cylinder locking device B.
Referring to Fig. 1,2,3, two pneuma-lock derricks, comprise three joint suit derricks, and derrick upper body 7, and in derrick, body 8, derrick lower body 9.On the derrick of three joints suits, the carrier bar place of middle body 7,8 inner sides installed on locking derrick, the cover of two between middle body 7,8 cylinder locking device A.Cylinder locking device A comprises that dihedral asks 2, and ask 2 one end and derrick upper body 7 spandrel girders are articulated and connected, and is connected with cylinder 5 piston ends simultaneously, and cylinder 5 other ends are connected with derrick upper body 7.Ask 2 under cylinder 5 effect around pivot pin 4 rotations.2 front ends that ask are furnished with circular arc limited block 1.
On derrick, middle body 7,8 cylinder locking device A are arranged on 7 carrier bars inner sides, derrick upper body, by limited block 1, ask 2, riser 3, pivot pin 4, double-acting cylinder 5, support plate 6 parts such as grade form.Cylinder 5 asks 2 rotation seats in derrick on body 8 carrier bars while stretching out, realize on derrick, middle body 7,8 locking functions.
Referring to Fig. 1,4,5, in derrick, the carrier bar place in lower body 8,9 outsides installed in locking derrick, the cover of two between lower body 8,9 cylinder locking device B.Cylinder locking device B comprises that dihedral asks 2, and ask 2 one end and derrick lower body 9 spandrel girders are articulated and connected, and is connected with cylinder 5 piston ends simultaneously, and cylinder 5 other ends are connected with derrick lower body 9.
In derrick, lower body 8,9 cylinder locking device B are arranged on derrick lower body 9 carrier bars outsides.Cylinder 5 asks 2 rotation seats on derrick lower body 9 carrier bars while stretching out, realize in derrick, lower body 8,9 locking functions.
Upper, the middle body 7,8 of three joint suit derricks is opened respectively the formula locking device that asks that upper and lower two cover double-acting cylinders 5 are controlled in telescopic process successively, realizes derrick locking function.
Claims (2)
