Abstract
The invention discloses a rotary drilling rig. A machine frame of the rotary drilling rig is provided with a mast extending in the vertical direction, a counter weight device matched with the mast and a drill rod parallel to the mast are detachably arranged on the machine frame, and a first middle mast is detachably arranged in the middle of the mast. The first middle mast is dismantled, so that the length of the whole mast is shortened, the counter weight device is dismantled simultaneously, the drill rod matched with the length of the mast at the time is reloaded, torque and pressure of the rotary drilling rig can be transmitted fully, and the rotary drilling rig can meet the operation requirements of rock entering construction; after the first middle mast is assembled on the mast again, the length of the whole mast can be lengthened, the counter weight device is assembled on the machine frame again, the drill rod matched with the length of the mast at the time is reloaded simultaneously, and accordingly the rotary drilling rig can have a large effectively drilling depth and can meet the operation requirements of deep hole pile construction.
Description
Technical field
The present invention relates to the engineering mechanical device technical field, particularly a kind of rotary drilling rig.
Background technology
Rotary drilling rig is a kind of piling machinery for the operation of building foundation engineering pore-forming, the advantages such as it has that speed of application is fast, hole quality good, environment pollution is little, flexible and convenient operation, security performance is high and applicability is strong, become the main pore-forming equipment of bored pile construction, be widely used in the ground foundation construction workss such as urban construction, highway bridge, highrise building.And, along with the improving constantly of user demand, people also have higher requirement to the service behaviour of rotary drilling rig.
In current existing rotary drilling rig operation process, in order to meet the boring needs of deep hole stake, its mast and drilling rod are generally longer, but longer drilling rod easily causes the depression bar in operation process unstable, and plus-pressure can't effectively be transmitted.While especially being entered the rock construction, because the intensity of rock is higher, in boring procedure, need rotary drilling rig to apply larger moment of torsion and plus-pressure, but because drilling rod is longer, depression bar is unstable, make to add compressive load and can not effectively transmit, thereby larger moment of torsion and plus-pressure can't be applied to scope of operation place, cause inconvenience to corresponding construction operation.
Therefore, how to make rotary drilling rig can realize the deep hole pile driving construction, can realize that again into the rock construction be the important technological problems that those skilled in the art need to solve at present.
Summary of the invention
The purpose of this invention is to provide a kind of rotary drilling rig, this rotary drilling rig can be realized the deep hole pile driving construction, can realize again constructing into rock.
For solving the problems of the technologies described above, the invention provides a kind of rotary drilling rig, comprise frame, be provided with the mast vertically extended on described frame, removably be provided with the counter weight device matched with described mast and the drilling rod paralleled with described mast on described frame, the middle part of described mast removably is provided with the first middle mast.
Preferably, described mast comprises upper mast, the second middle mast and the lower mast vertically connected successively from top to bottom, described the first middle mast is connected between described upper mast and described the second middle mast, and the bearing of trend of the axis of described upper mast, described the first middle mast, described the second middle mast and described lower mast is all consistent with vertical direction.
Relative above-mentioned background technology, rotary drilling rig provided by the present invention, comprise frame, be provided with the mast vertically extended on described frame, removably be provided with the counter weight device matched with described mast and the drilling rod paralleled with described mast on described frame, the middle part of described mast removably is provided with the first middle mast.In the course of work, described the first middle mast is unloaded, make the entire length of described mast shorten, and described counter weight device is unloaded, change the outfit and the suitable drilling rod of mast length now simultaneously, thereby make the moment of torsion of described rotary drilling rig and plus-pressure transmission more abundant, and then can meet the operation needs into the rock construction; After ressembling on described mast by described the first middle mast, can make the entire length of described mast extend, and described counter weight device is ressembled on described frame, change the outfit and the suitable drilling rod of mast length now simultaneously, thereby make described rotary drilling rig can possess larger effective drilling depth, and then can meet the operation needs of deep hole pile driving construction.
The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The assembly structure schematic diagram of the rotary drilling rig that Fig. 1 provides for a kind of specific embodiment of the present invention.
The specific embodiment
Core of the present invention is to provide a kind of rotary drilling rig, and this rotary drilling rig can be realized the deep hole pile driving construction, can realize again constructing into rock.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, the assembly structure schematic diagram of the rotary drilling rig that Fig. 1 provides for a kind of specific embodiment of the present invention.
In the specific embodiment, rotary drilling rig provided by the present invention, comprise frame 11, be provided with the mast vertically extended on frame 11, removably be provided with the counter weight device 14 matched with described mast and the drilling rod 13 paralleled with described mast on frame 11, the middle part of described mast removably is provided with the first middle mast 121.In the course of work, the first middle mast 121 is unloaded, make the entire length of described mast shorten, and counter weight device 14 is unloaded, change the outfit and the suitable drilling rod 13 of mast length now simultaneously, thereby make the moment of torsion of described rotary drilling rig and plus-pressure transmission more abundant, and then can meet the operation needs into the rock construction; After ressembling on described mast by the first middle mast 121, can make the entire length of described mast extend, and counter weight device 14 is ressembled on frame 11, change the outfit and the suitable drilling rod 13 of mast length now simultaneously, thereby make described rotary drilling rig can possess larger effective drilling depth, and then can meet the operation needs of deep hole pile driving construction.
Further, described mast comprises upper mast 122, the second middle mast 123 and the lower mast 124 vertically connected successively from top to bottom, the first middle mast 121 is connected between upper mast 122 and the second middle mast 123, and the bearing of trend of upper mast 122, the first middle mast 121, the second middle mast 123 and the axis of lower mast 124 is all consistent with vertical direction.It should be pointed out that above-mentioned mast is only preferred version for the four-part form structure be comprised of upper mast 122, the first middle mast 121, the second middle mast 123 and lower mast 124, the structure of this mast is not limited to the four-part form shown in figure; Simultaneously, the rigging position of above-mentioned the first middle mast 121 also is not limited between the upper mast 122 shown in figure and the second middle mast 123, so long as can meet the actual use needs of described rotary drilling rig, all can.
