Referring to fig. 2, the power head sliding frame disclosed by the utility model comprises a sliding frame box body 10 and an ear frame 20, wherein the ear frame 20 is movably arranged on the sliding frame box body 10, and the ear frame 20 can be switched between a fastening position and a dismounting position. When the ear rack 20 is in the fastening position, the ear rack 20 is fixed with the sliding rack box 10 to form a U-shaped structure to clamp the guide mast, so that the power head sliding rack drives the power head to slide along the guide mast; when the ear mount 20 is in the detached position, the ear mount 20 and carriage housing 10 release the clamping function of the guide mast so that the power head carriage can be removed from the guide mast for maintenance or replacement of the power head carriage.
In this embodiment, when the ear mount 20 is moved on the carriage case 10 to the extreme position near the central axis of the carriage case 10, the ear mount 20 is in the fastening position, and at this time, the ear mount 20 and the carriage case 10 need to clamp the guiding mast for sliding, so that the ear mount 20 and the carriage case 10 are fixed, usually by bolting. While maintaining the connection to the carriage housing 10 when the ear mount 20 is moved to the release position toward the other side of the secured position, without having to first release the ear mount 20 and then release the powerhead carriage.
According to the power head sliding frame provided by the embodiment of the utility model, when the power head sliding frame needs to be disassembled, only the ear frame 20 needs to be moved to the disassembling position, and the power head sliding frame can be operated by a single person without the help of other supporting tools or the cooperation of multiple persons to take down the ear frame 20, so that the construction efficiency is improved.
To further optimize the above solution, the ear mount 20 provided in the above embodiment is hinged to the carriage case 10 by a connecting pin 40, and the edge of the ear mount 20 is hinged to the outside of the carriage case 10 so that the ear mount 20 can be pivotally switched between the fastening position and the detaching position.
Referring to fig. 2, when the ear rack 20 rotates to the fastening position, the ear rack 20 is fastened to the carriage body 10 through the connecting bolt 30 and fixed to the carriage body 10 to form a U-shaped structure to hold the guiding mast for working; when the power head needs to be disassembled, the power head can be disassembled without disassembling the lug frame 20 by only disassembling the connecting bolt 30, rotating the lug frame 20 with the opening and closing design to the outer side of the sliding frame box body 10 along the connecting pin 40 and removing the clamping effect on the guide mast.
In another embodiment of the present invention, the ear rack 20 is slidably connected to the sliding rack box 10 to switch between a fastening position and a detaching position, a sliding slot is provided on the sliding rack box 10, the ear rack 20 corresponding to the sliding connection with the sliding rack box can slide on the sliding slot, a first limit position of the sliding slot is a fastening position of the ear rack 20, the ear rack 20 is fastened to the sliding rack box 10 by a connecting bolt 30 when sliding to the first limit position, and is fixed to the sliding rack box 10 to form a U-shaped structure to clamp the guiding mast for working; when the power head needs to be disassembled, the power head can be disassembled without disassembling the lug frame 20 by only disassembling the connecting bolt 30, sliding the lug frame 20 to the second limit position and releasing the clamping effect on the guide mast.
The carriage body 10 may be provided with a slide rail.
Referring to fig. 2, in the power head carriage provided in the above embodiment, a nylon plate 50 is disposed inside a U-shaped structure formed by the ear frame 20 and the carriage case 10, and the nylon plate 50 is in direct contact with the guide mast and is fastened to the ear frame 20 and the carriage case 10 by bolts.
Because the nylon plate 50 directly contacts with the guide mast, the abrasion frequency of the nylon plate 50 is higher in the using process, the daily maintenance difficulty and the cost of the power head sliding frame are increased, if the nylon plate 50 is not replaced timely, the working stability of the power head can be caused to be problematic, for example, the power head is shaken and clamped when being lifted and lowered. Referring to fig. 3 and 4, in order to further optimize the above technical solution, a lubrication point 60 is further provided on the carriage body 10 and the ear rack 20, the lubrication point 60 is of a counter bore structure and is provided with a through type pressure filling oil cup, and the through type pressure filling oil cup is filled with grease. In the working process of the power head, the sliding friction force of the contact surface of the nylon plate 50 and the guide mast is reduced under the action of lubricating grease, and the service life of the nylon plate 50 is prolonged, so that the replacement frequency of the nylon plate 50 is reduced, and the cost is saved.
In one embodiment of the present invention, four lugs are provided and are uniformly and symmetrically disposed on the carriage case 10, and two lugs are respectively disposed at upper and lower positions of both sides of the carriage case 10 to commonly clamp the guide masts.
Further, in the above embodiments. A lubricating point 60 is arranged on each of the four ear frames 20 to lubricate the nylon plate 50 on the ear frames 20; each of the connection locations of the carriage body 10 and the ear mount 20 is provided with a lubrication point 60 to lubricate the nylon panels 50 on the carriage body 10.
Referring to fig. 5, in the power head carriage provided in the above-described embodiment, the carriage case 10 includes an outer plate 110 and an inner plate 120, the inner plate 120 is wider in the width direction than the outer plate and extends out of the outer plate 110, and the inner plate 120 is thicker and is the highest-strength component of the carriage case 10, and the outer plate 110 and the inner plate 120 are welded by a first fillet a, rather than by a flat seam in which edges are connected up and down as in the prior art.
Further, the power head carriage comprises an ear plate 70 for connecting a power head bracket, referring to fig. 1, the ear plate 70 in the prior art is welded and connected with the edge in the carriage box 10 through a welding seam C, and the edge of the outer plate 110 is also welded and connected with the inner plate 120 through an edge flat welding seam, so that the welding seam C of the ear plate 70 is overlapped with the original welding seam during welding, the overlapped welding seam is easy to cause problems during nondestructive inspection of the welding seam, and therefore, construction needs to be stopped immediately and the power head needs to be detached for welding repair again, so that the construction period progress is delayed, and the result is immeasurable. Referring to fig. 5, in the embodiment of the present invention, one end of the ear plate 70 is directly welded to the inner plate 120, the weld between the ear plate 70 and the inner plate 120 is a second fillet weld B, and the second fillet weld B does not overlap with the first fillet weld a. Because the inner plate 120 is the highest-strength component of the carriage box 10, the lug plate 70 is directly welded on the inner plate 120, so that the torsional force and the pressure generated by the power head can be better transmitted and acted on the guide mast, and the second fillet weld B is not overlapped with the first fillet weld A due to the change of the welding mode, thereby improving the welding strength and prolonging the service life of the lug plate 70 and the carriage box 10.
The embodiment of the utility model also discloses a rotary drilling rig with the power head sliding frame disclosed by the embodiment. The power head sliding frame has all the technical effects of the power head sliding frame, and the details are not repeated herein.
