A positioning cylinder (7) is arranged at the lower end of a box body (3), an input shaft (2) is arranged at the upper end in the vertical direction of the box body (3), a coupling (1) capable of being connected with a drilling rod of the rotary drilling machine is arranged on the input shaft (2), an output shaft (6) in transmission connection with the input shaft (2) is arranged in the horizontal direction of the box body (3), and at least one end of the output shaft (6) is provided with a cutterhead. The rotary drilling machine edge cutting device for processing underground continuous grooves is driven by using an existing rotary drilling machine power source, is used for cutting residual corners to meet construction requirements, and is simple in structure, suitable for hostile rotary excavating working condition, high in working efficiency while being matched with the rotary drilling machine to be used and strong in applicability.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, is specifically related to a kind of and rotary drilling rig and supports the use, for the chamfered edge device of underground continuous channel.
Background technology
The exploitation of western salt mine in recent years become a major project of China's development of the West Regions, and the diversion works of Chaidamu Basin, Qinghai Province Golmudhe River is exactly one of them.The salt mine development technology is to utilize engineering equipment to dig groove on salt mine, quotes fresh water solid potassium mine dissolution is become to bittern, produces the products such as potash fertilizer after pervaporation is purified.The underground continuous channel of the wide about 2m of the dark about 40m of this requirement of engineering, because geology is very hard, general diaphragm wall grab bucket can't normal construction.And rotary drilling rig is while processing underground continuous channel, because the unbalance stress of drilling bucket produces radially unbalance loading, cause drilling rod constantly to be subject to shock loading and damage, destroyed the stability of equilibrium of rig whole simultaneously.So rotary drilling rig can only be processed with the interlock hole of certain center to center distance, but its residual corner (as shown in Fig. 4 8) can't meet construction requirement, therefore be badly in need of a kind of device of the chamfered edge for underground continuous channel of design.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of existing rotary drilling rig power source driving that utilizes, and the chamfered edge device of the rotary drilling rig of construction requirement for underground continuous channel processing cut to meet in the corner under residual.
In order to solve the problems of the technologies described above, the rotary drilling rig that the utility model provides is for the chamfered edge device of underground continuous channel processing, the lower end of casing is provided with positioning tube, the vertical direction upper end of described casing is provided with power shaft, described power shaft is provided with the shaft coupling that can be connected with the drilling rod of rotary drilling rig, on described casing, horizontal direction is provided with the output shaft be in transmission connection with described power shaft, and at least one end of described output shaft is provided with cutterhead.
Described power shaft and described output shaft adopt the circular cone bevel gear pair to be in transmission connection.
Described cutterhead is the bulb cutterhead.
Adopt the chamfered edge device of the rotary drilling rig of technique scheme for underground continuous channel processing, during construction, positioning tube is put into to the rotary drilling rig pore-forming, utilize the barrel of positioning tube the spacing of chamfered edge device integral body circumferencial direction that contacted with the pore-forming hole wall.Unit head on rotary drilling rig utilizes drilling rod to be connected with shaft coupling and is with the driven input shaft rotation on the one hand, then by a pair of circular cone bevel gear pair be connected with power shaft, moment of torsion is passed to output shaft, makes the ball head knife disc spins fixing with output shaft; Pressurization oil cylinder on rotary drilling rig passes to drilling rod by downward plus-pressure on the other hand, promotes the hole wall vertically down construction of whole chamfered edge device along pore-forming, thereby realizes the cutting of residual corner.
In sum, the utility model is a kind of existing rotary drilling rig power source driving that utilizes, and the chamfered edge device of the rotary drilling rig of construction requirement for underground continuous channel processing cut to meet in the corner under residual.The utility model is simple in structure, is applicable to revolving digging bad working environments.Support the use high efficiency with rotary drilling rig, applicability is strong.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that positioning tube structure master of the present utility model looks schematic diagram.
Fig. 3 is positioning tube structure schematic top plan view of the present utility model.
Fig. 4 is interlock hole schematic diagram after the construction of rotary drilling rig drilling bucket.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, the lower end of casing 3 is provided with positioning tube 7, casing 3 vertical direction upper ends are provided with power shaft 2, power shaft 2 is provided with the shaft coupling 1 that can be connected with the drilling rod of rotary drilling rig, on casing 3, horizontal direction is provided with output shaft 6, power shaft 2 adopts circular cone bevel gear pair 4 to be in transmission connection with output shaft 6, and the two ends of output shaft 6 are equipped with bulb cutterhead 5.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, during construction, positioning tube 7 is put into to the rotary drilling rig pore-forming, utilize the barrel of positioning tube 7 the spacing of the whole circumferencial direction of chamfered edge device that contacted with the pore-forming hole wall.Unit head on rotary drilling rig utilizes drilling rod to be connected with shaft coupling 1 and is with driven input shaft 2 rotations on the one hand, then by a pair of circular cone bevel gear pair 4 be connected with power shaft 2, moment of torsion is passed to output shaft 6, makes the bulb cutterhead fixing with output shaft 65 rotations; Pressurization oil cylinder on rotary drilling rig passes to drilling rod by downward plus-pressure on the other hand, promotes the hole wall vertically down construction of whole chamfered edge device along pore-forming, thereby realizes the cutting of residual corner.
The utility model is simple in structure, is applicable to revolving digging bad working environments.Support the use high efficiency with rotary drilling rig, applicability is strong.
