Description

Technical Field

[0001] This utility model relates to the field of pneumatic anchor drilling machine technology, and in particular to a pneumatic anchor drilling machine with an anti-tipping base. Background Technology

[0002] A pneumatic rock drill is a handheld or outrigger-mounted rock drilling device that uses compressed air as a power source and is specifically designed for drilling and installing rock bolts in mine roadways, tunnels, slope protection, and other engineering projects. The working principle of a pneumatic rock drill can be summarized as follows: compressed air drives a pneumatic motor to generate rotational power, which is transmitted to the drill rod or drill bit through a gear reduction mechanism for rock drilling. Simultaneously (for outrigger-mounted models), compressed air drives the outriggers to provide propulsion.

[0003] Some pneumatic anchor drilling rigs rely solely on simple outriggers or small trays for their bases, lacking a ring-shaped array of inclined support structures. This results in a small support area and weak resistance to lateral forces, making them prone to swaying or even overturning when the drilling rig generates strong vibrations or counter-torques during operation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pneumatic anchor drilling machine with an anti-tipping base.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pneumatic anchor drill with an anti-tipping base includes a pneumatic anchor drill body. A detachable base assembly is screwed to the bottom of the pneumatic anchor drill body. The base assembly includes a main base. Three sets of inclined support assemblies are arranged in a circular array at equal intervals on the outer wall of the main base. A detachable auxiliary assembly is provided at the bottom of the main base.

[0007] The auxiliary component includes an auxiliary base, with a steel nail anti-slip pad and a rubber pad respectively provided on the top and bottom of the auxiliary base via connecting rings.

[0008] In addition, a preferred structure is that the bottom of the main base is provided with a main slot for the auxiliary base to be inserted, and an auxiliary slot is provided inside the main base on one side of the main slot. The inner diameter of the auxiliary slot is the same as the outer diameter of the connecting ring, and the outer diameter of the connecting ring is smaller than the outer diameter of the auxiliary slot.

[0009] In addition, a preferred structure is that multiple magnetic limiting blocks are installed in a circular array at equal intervals on the side away from the auxiliary slot inside the main base.

[0010] In addition, a preferred structure is that the outer wall of the auxiliary base is provided with sliding grooves at the corresponding magnetic limiting blocks, and the top and bottom of the auxiliary base are provided with magnetic grooves on one side of the corresponding sliding grooves.

[0011] In addition, a preferred structure is that the height of the magnetic insertion groove is the same as the height of the magnetic limiting block, and a permanent magnet layer with the opposite polarity to the magnetic limiting block is provided on the side of the magnetic insertion groove away from the sliding groove.

[0012] Furthermore, in a preferred configuration, the inclined support assembly includes a mounting base, on which an inclined support rod is mounted via a fastening assembly, and at the other end of the inclined support rod is a support base mounted via a fastening assembly.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the detachable auxiliary components allow users to selectively install the steel nail anti-slip pad and the rubber pad according to their actual needs. The steel nail anti-slip pad can penetrate into soft ground, while the rubber pad is suitable for hard, flat ground. Furthermore, the three sets of circular array of inclined support components form a stable triangular support structure, increasing the support area and center of gravity projection range of the drilling rig and preventing the anchor drilling rig from overturning.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A pneumatic anchor drill with an anti-tipping base includes a pneumatic anchor drill body 1. A detachable base assembly 2 is screwed to the bottom of the pneumatic anchor drill body 1. The base assembly 2 includes a main base 21. Three sets of inclined support assemblies 23 are arranged in a circular array at equal intervals on the outer wall of the main base 21. A detachable auxiliary assembly 22 is provided at the bottom of the main base 21.

[0023] The auxiliary component 22 includes an auxiliary base 221, and the top and bottom of the auxiliary base 221 are respectively provided with a steel nail anti-slip pad layer 222 and a rubber pad layer 223 via connecting rings.

[0024] Meanwhile, the bottom of the main base 21 is provided with a main slot for the auxiliary base 221 to be inserted, and an auxiliary slot is provided inside the main base 21 on one side of the main slot. The inner diameter of the auxiliary slot is the same as the outer diameter of the connecting ring, and the outer diameter of the connecting ring is smaller than the outer diameter of the auxiliary slot.

[0025] Furthermore, multiple magnetic limiting blocks 4 are installed in a circular array at equal intervals on the side away from the auxiliary slot inside the main base 21.

[0026] Furthermore, the outer wall of the auxiliary base 221 is provided with sliding grooves 224 at the corresponding magnetic limiting blocks 4, and the top and bottom of the auxiliary base 221 are provided with magnetic grooves 225 on the side of the corresponding sliding groove.

[0027] Meanwhile, the height of the magnetic insertion groove 225 is the same as the height of the magnetic limiting block 4, and a permanent magnet layer with the opposite polarity to the magnetic limiting block 4 is provided on the side of the magnetic insertion groove 225 away from the sliding groove 224.

[0028] Furthermore, the inclined support assembly 23 includes a mounting base, on which an inclined support rod is provided by a fastening assembly, and at the other end of the inclined support rod is a support base provided by a fastening assembly, wherein the fastening assembly may be a hinge bolt and a lock nut.

[0029] It is worth noting that the magnetic limiting block 4 is a neodymium iron boron permanent magnet, and the specific structure, connection method, and working principle of the pneumatic anchor drilling rig body 1 are all existing technologies that are currently publicly available on the market, so they will not be described in detail.

[0030] Meanwhile, an extension ring 3 is installed at the bottom of the legs of the pneumatic anchor drill body 1. The outer wall of the extension ring 33 is provided with an external thread. The top of the main base 21 is provided with an installation groove at the extension ring 33, and the installation groove is provided with an internal thread at the external thread. The internal thread is threadedly connected to the external thread.

[0031] In this embodiment, the detachable auxiliary component 22 allows the steel nail anti-slip pad 222 to be inserted into soft ground, while the rubber pad 223 is suitable for hard, flat ground.

[0032] Meanwhile, users can selectively install the steel nail anti-slip pad 222 and the rubber pad 223 according to their actual needs. When the auxiliary component 22 needs to be disassembled, the auxiliary base 221 is rotated. During the rotation, its magnetic limit block 4 moves along the magnetic groove to the sliding groove and aligns with the sliding groove. Then the auxiliary component 22 can be taken out.

[0033] When the auxiliary component 22 needs to be installed, the magnetic limiting block 4 is aligned with its sliding groove and inserted until the auxiliary base 221 is fully inserted into the main slot, and its steel nail anti-slip pad layer 222 or rubber pad layer 223 is located in the auxiliary slot. The auxiliary component 22 is then rotated until it can no longer be rotated. After that, its magnetic limiting block 4 is magnetically connected to the permanent magnet layer of the magnetic insertion groove, thereby completing the installation of the auxiliary component 22.

[0034] The three sets of ring array of inclined support components 23 form a stable triangular support structure, which increases the support area and center of gravity projection range of the drilling rig, preventing the anchor drilling rig from overturning. The inclined support components 23 are connected to the locking nuts by hinge bolts, so that the support angle of the inclined support components 23 can be adjusted within a certain range.

[0035] In this invention, the detachable auxiliary component 22 allows users to selectively install the steel nail anti-slip pad 222 and the rubber pad 223 according to their actual needs. The steel nail anti-slip pad 222 can penetrate into soft ground, while the rubber pad 223 is suitable for hard, flat ground. Furthermore, the arrangement of three sets of circular array of inclined support components 23 forms a stable triangular support structure, increasing the support area and center of gravity projection range of the drilling rig and preventing the anchor drilling rig from overturning.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
