Abstract
The utility model discloses a drag-hanging mast structure, which comprises a bottom frame for connecting and supporting a main machine of a drilling machine. The rear two sides of the bottom frame are respectively hinged with a supporting shaft, and the front two sides of the bottom frame are respectively provided with a horizontal shaft in welding mode. The two hinged supporting shafts are respectively pivoted with a mast supporting leg, a tyre capable of rotating freely is arranged respectively on portions of the two mast supporting legs close to the hinged supporting shafts, the middle portions of the two mast supporting legs are respectively provided with hoops which can be fastened with the horizontal shafts, and the front sides of the two mast supporting legs are provided with cross beams for connecting and fixing the two mast supporting legs. Towing hooks are installed at the front ends of the cross beams and connected with the cross beams through springs. The centers of the tyres are arranged slightly behind the gravity center of the main machine of the drilling machine. The drag-hanging mast structure not only enables integral moving of the drilling machine to be light and convenient, but also can use the mast as a drilling tower supporting leg and can be used in dragging and hanging of integral transporation.
Description
Technical field
The utility model relates to a kind of device that is used for the carrying of engineering drilling equipment, particularly a kind of pull-type mast structure that can make things convenient for engineering driller construction transportation, resettlement to use.
Background technology
Present domestic engineering driller series is various, and form of structure is also had nothing in common with each other, but in whole Transporting and move, and substantially all is to adopt that the people lifts, steel cable draws or the crane dress hangs form.Because rig integral body is relatively heavier, factors such as construction plant restriction make rig difficult especially in the resettlement in building site.
Summary of the invention
The utility model purpose is, at the prior art deficiency, provides a kind of and can be convenient to the whole carrying of rig, pull-type mast structure simple in structure, multi-function.
For achieving the above object, the pull-type mast structure that the utility model provides comprises connecting the underframe that supports the rig main frame that the back both sides of this underframe are welded with hinged back shaft respectively, and preceding both sides are welded with transverse axis respectively; Be pivoted with the mast supporting leg respectively on the two hinged back shafts, near hinged back shaft place the tire that can rotate freely is housed respectively on the two mast supporting legs, the middle part of two mast supporting legs also is respectively equipped with the anchor ear that can fasten with transverse axis, and the front side of two mast supporting legs is equiped with the crossbeam that is used to be connected and fixed two mast supporting legs, and the front end of crossbeam is equipped with draw hook.
This draw hook is connected with crossbeam by spring.
The center summary of this tire is back partially in the center of gravity of rig main frame.
Advantage of the present utility model is: adopt the utility model pull-type mast structure, not only integral moving is light, and mast can pull usefulness when transportation is mobile, can make the boring tower supporting leg and use when work.
Description of drawings
Lateral view when Fig. 1 pulls for the utility model is used as.
Vertical view when Fig. 2 pulls for the utility model is used as.
Working state figure when Fig. 3 is used as the boring tower supporting leg for the utility model.
The specific embodiment
As shown in Figure 1-Figure 3, the utility model pull-type mast structure comprises the underframe 1 that connects support rig main frame 10, and the back both sides of this underframe 1 are welded with hinged back shaft 2, and the preceding both sides of this underframe 1 are welded with transverse axis 3; Be pivoted with the mast supporting leg 4 that can rotate freely around hinged back shaft 2 on the hinged back shaft 2 in both sides respectively, near hinged back shaft 2 places the tire 5 that can rotate freely is housed respectively on the two mast supporting legs 4, the middle part of two mast supporting legs 4 also is respectively equipped with the half-dozen open type anchor ear 6 that can fasten with both sides transverse axis 3, and the front side of two mast supporting legs 4 is equiped with the crossbeam 7 that is used to be connected and fixed two mast supporting legs 4, and the front end of crossbeam 7 is equipped with draw hook 8.For reducing to impact, this draw hook 8 is connected with crossbeam 7 by having the spring 9 that slows down the effect of dashing.
When needs carryings rig, crossbeam 7 is depressed into mast supporting leg 4 and transverse axis 3 when tangent, use half-dozen open type anchor ear 6 that mast supporting leg 4 and transverse axis 3 are coupled together.This moment underframe 1 lever power works with under break away from ground, tire 5 lands and bears the rig overall weight, and the center of tire 5 is slightly partially afterwards in the center of gravity of rig main frame 10.Gently lift draw hook 8 this moment, and rig just is in the transportation relocation state, and external force can realize moving of rig a little, also can use tractions such as locomotive when distance is far away, light to realize transportation.
When moving to the construction plant, press down crossbeam 7, unclamp half-dozen open type anchor ear 6 mast supporting leg 4 is separated with transverse axis 3, slowly lift crossbeam 7, make progressively kiss the earth of underframe 1, tire 5 no longer bears support force.And boring tower 11, two mast supporting legs 4 need be installed when rig is worked in addition can prop up after-poppet as boring tower 11, crossbeam 7 makes rig enter duty as the fixedly connected beam of boring tower 11.
Claims (3)
1. a pull-type mast structure comprises connecting the underframe that supports the rig main frame, and it is characterized in that the back both sides of this underframe are welded with hinged back shaft respectively, preceding both sides are welded with transverse axis respectively; Be pivoted with the mast supporting leg respectively on the two hinged back shafts, near hinged back shaft place the tire that can rotate freely is housed respectively on the two mast supporting legs, the middle part of two mast supporting legs also is respectively equipped with the anchor ear that can fasten with transverse axis, and the front side of two mast supporting legs is equiped with the crossbeam that is used to be connected and fixed two mast supporting legs, and the front end of crossbeam is equipped with draw hook.
