Abstract
The utility model relates to a folding type derrick for a drilling bit. The utility model mainly solves the problems the assembly and the disassembly of a derrick of the existing drilling bit is laborious and timeconsuming. The utility model is characterized in that the inner side of an upper derrick (1) and the inner side of a lower derrick (2) are hinged, and a hydraulic cylinder (4) is hinged between the upper derrick (1) and a platform (3) of the drilling bit in a hinge mode. The drilling bit uses the folding type derrick to solve the problems of laborious and timeconsuming assembly and laborious and timeconsuming disassembly. The utility model has the characteristics of simple structure, convenient use and safety.
Description
Technical field:
The utility model relates to rig derrick in the geological exploration field, belongs to a kind of rig jack-knife derrick.
Background technology:
In the geological prospecting process; generally adopted because the walking of vehicular rig is convenient; usually can run into various landform in this process; the drilling well in special forest belt; because the derrick of vehicular rig is a monolithic construction; when passing through the forest belt, damage forest easily; for reaching the purpose of environmental protection; overall dimensions when requiring the vehicular rig to travel should be in the forest spacing distance; derrick wherein can't damage forest when guaranteeing height, the standing form that split connects, the time-consuming effort of installing/dismounting when drilling well like this counted; and then influence drilling efficiency, make drilling efficiency low.
The utility model content:
In order to overcome the deficiency of the time-consuming effort of existing drilling derrick installing/dismounting, the utility model provides a kind of rig jack-knife derrick, this rig has solved the problem of the time-consuming effort of installing/dismounting with jack-knife derrick, has simple in structure, easy to use and safe and reliable characteristics.
The technical solution of the utility model is: this rig comprises upper and lower derrick and drilling machine platform with jack-knife derrick, and following derrick is fixed on the drilling machine platform, and the hinged inside of upper and lower derrick is hinged with hydraulic cylinder between last derrick and the drilling machine platform.
Be fixed with support on the above-mentioned drilling machine platform; The corresponding position in the upper and lower derrick outside has draw-in groove and lock pin respectively.
The utlity model has following beneficial effect: owing to take the hinged inside of the upper and lower derrick in the such scheme, be hinged with hydraulic cylinder between last derrick and the drilling machine platform, the flexible of hydraulic cylinder can be realized setting up and keeping flat of derrick, solved the problem that split type derrick installation dismounting is wasted time and energy, improve drilling efficiency, when last derrick keeps flat, be convenient in the forest belt, pass through simultaneously, do not damaged forest, help environmental protection, simple in structure, easy to use and safe and reliable.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-goes up derrick, derrick under the 2-, 3-drilling machine platform, 4-hydraulic cylinder, 5-support, 6-draw-in groove, 7-lock pin among the figure.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this rig comprises upper and lower derrick (1,2) and drilling machine platform 3 with jack-knife derrick, following derrick is fixed on the drilling machine platform 3, the hinged inside of upper and lower derrick (1,2) is hinged with hydraulic cylinder 4 between last derrick 1 and the drilling machine platform 3, when drill drilling is worked, derrick 1 moved upward and makes itself and following derrick 2 point-blank on hydraulic cylinder 4 stretched out and supports, and the corresponding position in upper and lower derrick (1, the 2) outside has draw-in groove 6 and lock pin 7 respectively, upper and lower derrick (1,2) location and locking; After drilling well finishes, open lock pin 7, hydraulic cylinder 4 retractions drive to be gone up derrick 1 and gets back to horizontal level, is fixed with support 5 on the drilling machine platform 3, and support 5 is used for attached helping and supports and the fixing derrick 1 of going up, and makes it steadily and not produce swing when rig is walked.
In sum, this rig with jack-knife derrick can be by hydraulic cylinder the setting up and keeping flat of flexible realization derrick, both solved the problem that split type derrick installation dismounting is wasted time and energy, having solved the monolithic derrick again, to set level the back long and pass through the problem of forest zone difficulty, improve drilling efficiency, when last derrick 1 keeps flat, be convenient in the forest belt, pass through simultaneously, do not damaged forest, help environmental protection, simple in structure, easy to use and safe and reliable.
Claims (3)
1, a kind of rig jack-knife derrick comprises upper and lower derrick (1,2) and drilling machine platform (3), following derrick is fixed on the drilling machine platform (3), it is characterized in that: the hinged inside of upper and lower derrick (1,2) is hinged with hydraulic cylinder (4) between last derrick (1) and the drilling machine platform (3).
2, a kind of rig jack-knife derrick according to claim 1 is characterized in that: be fixed with support (5) on the drilling machine platform (3).
