Abstract
The utility model discloses a novel derrick bears mechanism, its characterized in that: include the carrier block, locate the telescoping device and the connecting seat of carrier block one side, a carrier block terminal surface is equipped with a hole, the telescoping device include the connecting rod, with connecting rod one end articulated connecting block and with the fixed double -screw bolt together of connecting block, the connecting rod other end articulates there is the connecting seat, the connecting seat top is equipped with limitedly the connecting rod is movement track's limiting plate the farthest, the double -screw bolt passes through the silk hole with the carrier block links to each other. Compared with the prior art, the utility model discloses simple structure, reasonable in design, the input cost is low, creative adoption lever principle, the safe and stable when telescoping device stretches out can accurately target in place moreover, guarantee the hang down straightness and the stability of derrick, has satisfied all load of bearing the derrick upper part of the body and has transmitted the requirement for the lower part of the body, has guaranteed steadily going on of well drilling work, has improved work efficiency.
Description
Technical field
The utility model relates to oil-well rig equipment technical field, is specifically related to a kind of headframe load carrier.
Background technology
The derrick that oil-well rig equipment includes is usually split type, load carrier is the connection member of lower body on derrick, need all load that derrick upper body born by load carrier when actually used and pass to lower body, load carrier conventional at present, inadequate safety and steady when stretching out, often can not be accurately positioned, and in real work, perpendicularity and the stability of derrick can not be completely secured, have impact on steadily carrying out of drilling well work, reduce operating efficiency.
Utility model content
For solving drawbacks described above, the purpose of this utility model is to provide a kind of headframe load carrier, and simple in construction is reasonable in design, safety and steady during use, meets the requirement ensureing derrick perpendicularity and stability.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of headframe load carrier, including carrier block, the retractor device being located at described carrier block side and connection seat, described carrier block end face is provided with a hole, described retractor device includes the connecting rod contiguous block hinged with described connecting rod one end and the stud being fixed together with described contiguous block, the described connecting rod other end is hinged with connection seat, described connection seat is arranged over limiting the limiting plate of the farthest movement locus of described connecting rod, and described stud is connected with described carrier block by described silk hole.
Preferably, described carrier block is additionally provided with the flat-headed pin for external connection.
Described connecting rod and described contiguous block hinged place are provided with flat-headed pin.
Described connecting rod is provided with spring clip with the described seat hinged place that is connected.
In use, connecting rod one end is by external force, and described carrier block is gradually retracted to side, treats that external force disappears, and described spring clip firmly gives connecting rod, and described carrier block gradually stretches out to side for the utility model；Connecting rod is in loading process, and described limiting plate is for limiting the farthest movement locus of described connecting rod.
Compared with prior art, the utility model simple in construction, reasonable in design, input cost is low, and creative have employed lever principle, safety and steady when described retractor device stretches out, and can accurately put in place, it is ensured that the perpendicularity of derrick and stability, meet all load born derrick upper body and pass to the requirement of lower body, ensure that what drilling well worked is steadily carried out, improve operating efficiency.
Brief description
Below according to drawings and Examples, structure and features of the present utility model is further described.
Fig. 1 is structural representation of the present utility model.
In accompanying drawing 1,1. flat-headed pin, 2. carrier block, 3. stud, 4. contiguous block, 5. connect seat, 6. connecting rod, 7. Spring Card, 8. limiting plate.
Detailed description of the invention
Referring in accompanying drawing 1, a kind of headframe load carrier, including carrier block the 2nd, be located at described carrier block 2 side retractor device and connection seat 5, described carrier block 2 end face is provided with a hole, described retractor device includes connecting rod 6 contiguous block 4 hinged with described connecting rod 6 one end and the stud 3 being fixed together with described contiguous block 4, described connecting rod 6 other end is hinged with connection seat 5, described connection seat 5 is arranged over limiting the limiting plate 8 of the farthest movement locus of described connecting rod 6, and described stud 3 is connected with described carrier block 2 by described silk hole.
Preferably, described carrier block 2 is additionally provided with the flat-headed pin 1 for external connection.
Described connecting rod 6 is provided with flat-headed pin 1 with described contiguous block 4 hinged place.
Described connecting rod 6 is additionally provided with spring clip 7 with described seat 5 hinged place that is connected.
In use, connecting rod one end is by external force, and described carrier block is gradually retracted to side, treats that external force disappears, and described spring clip firmly gives connecting rod, and described carrier block gradually stretches out to side for the utility model；Connecting rod is in loading process, and described limiting plate is for limiting the farthest movement locus of described connecting rod.
The utility model simple in construction, reasonable in design, input cost is low, creative have employed lever principle, safety and steady when described retractor device stretches out, and can accurately put in place, ensure perpendicularity and the stability of derrick, meet all load born derrick upper body and pass to the requirement of lower body, it is ensured that steadily carrying out of drilling well work, improve operating efficiency.
Described above is only preferred embodiment of the present utility model; above-mentioned specific embodiment is not to restriction of the present utility model; retouching, modification or the equivalent that all those of ordinary skill in the art are made as described above, belongs to protection domain of the present utility model.
