Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Refer to Figures 1 - 6 , a drill suitable for a narrow working surface in a steep and inclined area provided in this embodiment includes a mobile trolley 1. A vertical frame 2 is hinged to the top of the mobile trolley 1, and a hydraulic telescopic rod 3 is hinged between the vertical frame 2 and the mobile trolley 1. An installation frame 4 is detachably installed on the vertical frame 2, and a hole-forming assembly 6 is driven by a hydraulic drive assembly 5 on the installation frame 4 to move along the length direction of the installation frame 4.

[0026] In the present invention, during the pile foundation construction of a narrow working surface in a steep and inclined area, first transport each module of the drill to the working site, then the hydraulic telescopic rod 3 drives the vertical frame 2 to stand up, install and fix the installation frame 4 on the vertical frame 2, then install the hole-forming assembly 6 on the driving end of the hydraulic drive assembly 5 of the installation frame 4, and then use the hole-forming assembly 6 to cooperate with the hydraulic drive assembly 5 to perform pile foundation hole-forming operations. The drill with detachable modules can be flexibly adjusted according to the actual terrain and working space. The detachable engineering drill can quickly complete the assembly and disassembly of the modules, shorten the equipment preparation time, and improve the operation efficiency.

[0027] Specifically, as Figures 1 - 4As shown, a connecting arm 41 is provided on the mounting frame 4, a slot 22 matching the connecting arm 41 is provided on the vertical frame 2, a connecting frame 21 consistent with the opening of the slot 22 is provided on the vertical frame 2, a locking bolt 23 is provided on the connecting frame 21, and a connecting screw hole 42 matching the locking bolt 23 is provided on the connecting arm 41.

[0028] Among them, after the stand 2 is erected by the hydraulic telescopic rod 3, the connecting arm 41 of the mounting frame 4 is inserted into the slot 22 of the stand 2, and the connecting frame 21 on the side of the slot 22 on the stand 2 is consistent with the opening of the slot 22, so that the connecting arm 41 extending from the slot 22 is simultaneously inserted into the connecting frame 21, and then the locking bolt 23 on the connecting frame 21 is screwed into the connecting screw hole 42 of the connecting arm 41 to achieve the connection and fixation of the mounting frame 4 and the stand 2. When disassembling, it is only necessary to unscrew the locking bolt 23 to disengage it from the connecting screw hole 42 of the connecting arm 41. It is simple and convenient, convenient for installation and disassembly of the drilling rig, and then convenient for transportation, so that the drilling rig can be flexibly adjusted according to the actual terrain and working space.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, the hydraulic drive assembly 5 includes a hydraulic motor 51 arranged on the top of the mounting frame 4, and the output end of the hydraulic motor 51 is fixedly connected to a screw 52 arranged along the length direction of the mounting frame 4. The screw 52 is provided with a slide 53 that cooperates with its thread. The hydraulic drive assembly 5 also includes a slide rail 54 fixed on the mounting frame 4.

[0030] Among them, when the hydraulic motor 51 is started, it drives the screw 52 to rotate, so that the slide 53 that cooperates with it on the screw 52 moves linearly on the screw 52, and the slide 53 cooperates with the slide rail 54 to ensure that the slide 53 can move smoothly and accurately when moving, and then drive the hole-forming component 6 to move stably to ensure the accuracy of punching.

[0031] Specifically, such as Figure 2 and Figure 5 As shown, the hole forming assembly 6 includes a connecting seat 61 detachably connected to the slide 53 , a motor group 62 is provided on the connecting seat 61 , and an output end of the motor group 62 is connected to a barrel drill 64 through a guide rod 63 .

[0032] Among them, the connecting seat 61 and the sliding seat 53 are detachably connected by fasteners, so that the hole-forming component 6 can be separated from the mounting frame 4, which is convenient for transporting the drilling rig and adapting it to the use needs of narrow working surfaces in steep areas. When drilling the pile foundation, the motor group 62 drives the barrel drill 64 on the guide rod 63 to rotate, and the barrel drill 64 drills the hole, and cooperates with the hydraulic drive component 5 to press the hole-forming component 6 downward, so that the hole-forming component 6 forms a pile foundation hole on the ground.

[0033] Specifically, such asFigure 5 and Figure 6 As shown, the guide rod 63 includes a connecting section 631 connected to the output end of the motor group 62 and a mounting section 632 connected to the barrel drill 64 . At least one intermediate section 633 is provided between the connecting section 631 and the mounting section 632 .

[0034] Among them, the guide rod 63 is divided into three parts: a connecting section 631, a mounting section 632 and an intermediate section 633. The intermediate section 633 is used to adjust the length of the guide rod 63. The length of the guide rod 63 is changed by adding or reducing the intermediate sections 633. The segmented guide rod 63 allows the digging depth of the drilling rig to be adjusted according to actual needs. When deeper digging is required, it can be achieved by increasing the number of intermediate sections 633. Conversely, when the digging depth is shallow, the number of sections can be reduced, thereby avoiding unnecessary material waste and weight increase.

[0035] It should be noted that a connecting block 634 is provided at one end of the middle section 633 , and a groove 635 matching with the connecting block 634 is provided at the other end of the middle section 633 , and a mounting bolt 636 passes through the connecting block 634 .

[0036] When connecting several intermediate sections 633, the connecting blocks 634 of the intermediate sections 633 are connected to the grooves 635 of the adjacent intermediate sections 633 by mortise and tenon joints, and then fixed by installing bolts 636. When the excavation depth needs to be increased, several intermediate sections 633 can be connected and fixed together.

[0037] The connecting section 631 also has a groove 635 that matches the connecting block 634, and the mounting section 632 also has a connecting block 634 that matches the groove 635, so that after several intermediate sections 633 are assembled, they can also be connected to the connecting section 631 and the mounting section 632.

[0038] Specifically, such as Figure 2 and Figure 5 As shown, a rotary pipe joint 65 is provided on the top of the drill rig 64. The rotary pipe joint 65 can be connected to a water pipe to cool the drill rig 64 during drilling construction. After the pile is formed, it can be connected to the pumping mechanism of the slurry storage tank for grouting. This enables the drilling rig to perform environmentally friendly and economical operations, realizing efficient and miniaturized construction of micro-cast-in-place piles.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
