Abstract
The invention discloses a gear box floating structure of a drilling machine power head. The gear box floating structure comprises a push-and-pull seat and four push-and-pull motors arranged on the push-and-pull seat, wherein two push-and-pull sliding seats are arranged on the push-and-pull seat and fixedly arranged on the push-and-pull seat through bolts; a chute is formed on the inner side of each push-and-pull sliding seat; a baffle block is arranged on each push-and-pull sliding seat at two ends of each chute; a gear box body is arranged on the chutes between the two push-and-pull sliding seats in a sliding mode and is connected with a spindle; and spindle driving motors are symmetrically arranged on two sides of the upper end of the gear box body. The gear box floating structure has the advantages that: the structure is more compact and simpler, is more reasonably arranged, is convenient to assemble, has a wide speed regulation range, a wide torque range, a high power utilization rate and high adaptability to the change of an external load, performs stepless speed regulation conveniently, and the like, and the drilling machine power head is driven in a hydraulic volumetric speed regulation mode; meanwhile, threads of a drill rod cannot be damaged when the drill rod of a drilling machine is detached, and the service life of the drill rod is prolonged.
Description
Technical field
The present invention relates to a kind of construction machine, relate in particular to a kind of drill power head gear-box floating construction.
Background technology
Traditional drill power head adopts the main shaft floating construction; Through an inside and outside spline housing is fixed in the gear-box gear wheel, collar bush moves main shaft and realizes that main shaft floats in inside and outside spline housing; Spacing through the front and back nut again; Existing main shaft floating construction installing/dismounting is complicated, and process component quantity is many, and cost is high, fault rate is high.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of structure simple more, arrange more reasonable, the drill power head gear-box floating construction of easy-maintaining.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: drill power head gear-box floating construction comprises: the push-and-pull seat be arranged on four push-and-pull motors on the push-and-pull seat; The push-and-pull seat is provided with two push-and-pull slip bases; On the push-and-pull slip base, be provided with some screw holes, the push-and-pull slip base is arranged on the push-and-pull seat through bolt, in the inboard of push-and-pull slip base chute is set; On the push-and-pull slip base at chute two ends, block is set; Gear housing is slidingly arranged between the two push-and-pull slip bases on the chute, on gear housing, is connected with main shaft, on the both sides, upper end of gear housing, is symmetrically arranged with the main shaft drives motor.
Advantage of the present invention is: above-mentioned drill power head gear-box floating construction, structure are compact more, simple, and it is more reasonable to arrange; Easy to assembly; Drill power head drives and adopts volumetric speed control hydraulic pressure, has advantages such as speed adjustable range is big, torque range is wide, stepless speed regulation is convenient, power utilization is high, the compliance of external load variations is strong, simultaneously; Can guarantee that rig drill rod thread when unloading drilling rod is injury-free, improve the application life of drilling rod.
Description of drawings
Fig. 1 is the structural representation of drill power head gear-box floating construction of the present invention.
Fig. 2 is the plan structure sketch map of Fig. 1.
Fig. 3 is the structural representation of push-and-pull slip base among Fig. 1.
Among the figure: 1, push-and-pull seat, 2, the push-and-pull motor, 3, the push-and-pull slip base, 4, screw hole, 5, bolt, 6, chute, 7, block, 8, gear housing, 9, main shaft, 10, the main shaft drives motor.
The specific embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and instantiation.
Like Fig. 1, Fig. 2, shown in Figure 3, drill power head gear-box floating construction comprises: push-and-pull seat 1 be arranged on four push-and-pull motors 2 on the push-and-pull seat 1; Push-and-pull seat 1 is provided with two push-and-pull slip bases 3; On push-and-pull slip base 3, be provided with some screw holes 4, push-and-pull slip base 3 is fixedly installed on the push-and-pull seat 1 through bolt 5, in the inboard of push-and-pull slip base 3 chute 6 is set; On the push-and-pull slip base 3 at chute 6 two ends, block 7 is set; Gear housing 8 is slidingly arranged between the two push-and-pull slip bases 3 on the chute 6, on gear housing 8, is connected with main shaft 9, on the both sides, upper end of gear housing 8, is symmetrically arranged with main shaft drives motor 10.
During use, gear housing 8 slides in chute 6, and 7 pairs of gear housings 8 of block play position-limiting action, and two main shaft drives motors 10 are realized the gyration of dynamic head main spindle 9, and four push-and-pull motors 2 realize that creeping into time haul of dynamic head main spindle 9 is moving.
Above-mentioned drill power head gear-box floating construction, structure are compact more, simple, and it is more reasonable to arrange; Easy to assembly; Drill power head drives and adopts volumetric speed control hydraulic pressure, has advantages such as speed adjustable range is big, torque range is wide, stepless speed regulation is convenient, power utilization is high, the compliance of external load variations is strong, simultaneously; Can guarantee that rig drill rod thread when unloading drilling rod is injury-free, improve the application life of drilling rod.
