DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 as well as Figure 2 As shown, an embodiment of the present invention proposes a height-adjustable drilling device, including: a base 1, a mounting rod 2, a mounting cylinder 4, a telescopic rod 5 and an electric drill 6, there are at least three mounting rods 2, each mounting rod 2 is fixed to the side wall of the base 1 through a mounting piece, a universal wheel 3 is provided at the bottom of each mounting rod 2, the mounting cylinder 4 is fixed to the top of the base 1, the telescopic rod 5 is slidably connected with the mounting cylinder 4 in the vertical direction, a locking assembly for locking the telescopic rod 5 and the mounting cylinder 4 is provided on the mounting cylinder 4, and the electric drill 6 is fixed to the side wall of the telescopic rod 5 through the mounting assembly.

[0023] By connecting the telescopic rod 5 and the mounting tube 4 in a sliding manner in the vertical direction, the length of the telescopic rod 5 extending out of the mounting tube 4 can be adjusted according to the height of the hole to be drilled, so that the electric drill 6 can reach the specified height, and then the telescopic rod 5 and the mounting tube 4 are locked by the locking assembly; the above method improves the applicability of the drilling equipment, avoids the safety risks brought by the traditional drilling method of climbing a mobile scaffold for drilling, and ensures the safety of workers to a certain extent.

[0024] like Figure 3As shown, the locking assembly includes: a cross bar 7, two cross bars 7, and the two cross bars 7 are respectively fixed to the two side walls of the mounting tube 4, and a mounting block 8 is fixedly arranged on the top of each cross bar 7 through a bracket 9, and an elastic locking member is arranged on each mounting block 8, and a plurality of locking holes evenly distributed in the vertical direction are arranged on the two side walls of the telescopic rod 5, and the elastic locking member is used to cooperate with the locking holes to lock the telescopic rod 5. Each of the elastic locking members includes: a clip 12, a second spring 11, and a pull rope 13, and a groove 10 is arranged on the side wall of the mounting block 8 close to the telescopic rod 5, and the second spring 11 is arranged in the groove 10, and one end of the clip 12 is slidably arranged in the groove 10, and the clip 12 is inserted into the locking hole under the elastic force of the second spring 11, and one end of the pull rope 13 is fixed to the end of the clip 12 away from the telescopic rod 5, and the other end of the pull rope 13 passes through the mounting block 8.

[0025] Specifically, when the telescopic rod 5 needs to be adjusted, the pull rope 13 is pulled so that the pull rope 13 pulls the clip 12 out of the locking hole, and the telescopic rod 5 can be adjusted to move in the vertical direction. After the position of the telescopic rod 5 is adjusted, the position of the telescopic rod 5 is fine-tuned so that the clip 12 is closest to the locking hole, and then the pull rope 13 is released. Under the elastic force of the second spring 11, the clip 12 is inserted into the locking hole aligned with it, thereby fixing the telescopic rod 5.

[0026] Furthermore, a pull ring 14 is provided at one end of each of the pull ropes 13 extending out of the mounting block 8, and a hook 15 for hanging the pull ring 14 is provided on the bracket 9. The pull ring 14 can be used to facilitate pulling the pull rope 13, and the setting of the hook 15 can also hang the pull ring 14 on the hook 15, so that the clamp 12 remains disengaged from the locking hole.

[0027] like Figure 4 As shown, the mounting assembly includes: a base plate 21, a mounting plate 17 and a transverse plate 16, the transverse plate 16 is fixed to the side wall of the telescopic rod 5, the side wall of the telescopic rod 5 is also provided with a mounting seat 18, one end of the mounting plate 17 is hinged to the mounting seat 18, the transverse plate 16 is located below the mounting plate 17, a second hydraulic cylinder 19 is provided on the top of the transverse plate 16, the output end of the second hydraulic cylinder 19 is hinged to the free end of the mounting plate 17, a first hydraulic cylinder 20 is provided on the top of the mounting plate 17, the base plate 21 is fixed to the output end of the first hydraulic cylinder 20, and the electric drill 6 is fixed to the top of the base plate 21 by a screw 22.

[0028] Through the design of the mounting assembly, when the base 1 stands on an uneven ground, the free end of the mounting plate 17 can be driven to move in the vertical direction by the second hydraulic cylinder 19, so that the first hydraulic cylinder 20 on the top of the mounting plate 17 can be in a horizontal state, thereby keeping the electric drill 6 on the top of the base plate 21 in a horizontal state. At the same time, in order to facilitate the judgment of whether the mounting plate 17 is in a horizontal state, a level 23 is provided on the top of the mounting plate 17; at the same time, when the electric drill 6 is powered on, the first hydraulic cylinder 20 can drive the base plate 21 to move in the vertical direction, so that the electric drill 6 is close to the position to be drilled, which is convenient for the electric drill 6 to drill holes.

[0029] like Figure 1 as well as Figure 2 As shown, each of the mounting parts includes: a bolt 24, and the end of each mounting rod 2 is rotatably connected to the base 1. The base 1 and the mounting rod 2 are both provided with threaded holes matching the bolts 24, and the bolts 24 are used to fix the base 1 and the mounting rod 2 and keep the mounting rod 2 horizontal. The side wall of the mounting cylinder 4 is provided with a fixing seat 25 corresponding to the number of the mounting rods 2, and the fixing seat 25 is provided with a limiting mechanism for limiting the mounting rods 2.

[0030] like Figure 5 As shown, each of the limiting mechanisms includes a limit seat 27 and a first spring 28, and a side wall of each fixing seat 25 facing away from the mounting tube 4 is provided with a limit groove 29, and both side walls of the limit groove 29 are provided with mounting grooves 26, and each mounting groove 26 is provided with a first spring 28 and a limit seat 27, and the limit seat 27 is slidably connected to the mounting groove 26, and the limit seat 27 is inserted into the limit groove 29 under the elastic force of the first spring 28.

[0031] Specifically, the mounting rod 2 is rotatably connected to the base 1. When the drilling device needs to be stored, the bolt 24 is first controlled to release the mounting rod 2, and then the mounting rod 2 is rotated toward the mounting tube 4 to insert the mounting rod 2 into the corresponding limiting groove 29 on the fixing seat 25. It is worth noting that when the mounting rod 2 is released from the fixing seat 25, the limiting seat 27 needs to be pushed to push it into the mounting groove 26 to prevent the limiting seat 27 from blocking the mounting rod 2 from being inserted into the limiting groove 29. Further, as shown in FIG. Figure 6 As shown, an arc-shaped protrusion 30 is provided on the side of the limit seat 27 away from the mounting groove 26, that is, when the mounting rod 2 contacts the protrusion 30 of the limit seat 27, the mounting rod 2 is pushed with force, and the mounting rod 2 can push the protrusion 30, so that the limit seat 27 is inserted into the mounting groove 26, thereby eliminating the need to manually push the limit seat 27 to push it into the mounting groove 26, thereby improving the efficiency of storing and folding the mounting rod 2. At the same time, when releasing the mounting rod 2, it is only necessary to push the mounting rod 2 with force to overcome the elastic force of the first spring 28.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
