Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
As shown in fig. 1 to 3, a short body power head structure is disclosed, which includes a push-pull box body 1, a push-pull speed reducer 5, and a push-pull gear 9, wherein the push-pull speed reducer 5 is provided on the push-pull box body 1, one end of the push-pull speed reducer 5 is connected with an output end not shown in the drawing of a push-pull motor, the output end is connected with the push-pull gear 9, the push-pull gear 9 is engaged with the push-pull gear 9 through a gear rack, a rack adapted to the push-pull gear 9 is provided on a drill frame 2, the push-pull motor provides power input to realize the forward and backward movement of the power head, and the push-pull pinion 9 is fixed on the push-pull box body 1 through a bearing. As shown in fig. 3, different from the arrangement of the conventional push-pull box speed reducers, the connecting lines of the rotary box 4 and the push-pull speed reducers 5 on the two sides are completely or partially overlapped, the rotary box 4 is partially or completely arranged on the connecting lines of the two push-pull speed reducers 5 to shorten the size of the power head in the length direction, and the number of the push-pull speed reducers 5 is reasonably arranged according to construction requirements.
In this embodiment, the slider structure 6 may be a roller, the slider structure 6 should be as far away from the push-pull speed reducer 5 as possible in the length direction of the power head, the slider structure 6 is fixed on the push-pull box body 1, the surface of the slider structure 6 is matched with the side plane of the rack of the drilling rig 2, and the slider structure 6 is used for offsetting radial force or deflection generated in the transmission process of the gear rack, so as to ensure the stability of the forward and backward movement process of the power head.
In the embodiment, a hook plate 10 matched with the drilling rig 2 is arranged below the push-pull box body 1, and the hook plate 10 is fixed at the lowest end of the push-pull box body 1 and matched with the lower surface of a rack of the drilling rig 2 and used for counteracting a torque effect generated by a propelling force/a back dragging force in the front-back movement process of the power head; the hook plate 10 can adopt a plurality of split hook plates and is fixed on the push-pull box body 1; or two integral hook plates can be fixed on the push-pull box body 1.
In the present embodiment, the rotary case 4 is provided with a rotary motor 3, and the rotary motor 3 is provided with a drive spindle 8. In order to ensure a better visual field and shorten the size of the power head in the driller construction process, a low-speed large-torque motor is adopted as the rotary motor 3. The front and back floating of the power head can adopt box body floating or main shaft floating, and the front end of the main shaft 8 is connected with a short protection joint which is easy to replace.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
