Description

Technical Field

[0001] The utility model relates to the technical field of anchor drilling machines, in particular to an adjustable pneumatic anchor drilling machine. Background Art

[0002] Anchor support is a fast, safe, economical and reliable way to support tunnels. Anchor drilling rigs are support equipment specially used for drilling holes in the roof and side walls of underground tunnels and installing anchor bolts. Among them, pneumatic rotary anchor drilling rigs are the preferred products on the current market because of their advantages such as small size, light weight and easy operation. Existing pneumatic anchor drilling rigs usually have a freely rotatable operating arm so that the angle can be adjusted as needed during the drilling process.

[0003] However, as the drilling depth continues to increase, the drill rig body is constantly lifted, and the workers hold the operating arm of the drill rig to maintain a suitable angle with the drill rig body. However, after adjusting to a suitable angle, due to the lack of effective support and fixation between the operating arm and the drill rig body, the workers still need to actively maintain the angle unchanged, which not only increases the labor intensity of the workers, but may also lead to a decrease in drilling accuracy and even cause safety accidents.

[0022] The principles and structures of the present application will be described in detail below in combination with the drawings and examples.

[0023] Please refer to Figures 1-6 A adjustable pneumatic anchor rod drill, including main body 1 and operating arm 2, operating arm 2 is rotatably connected to the upper part of main body 1, hoop 3 is fixedly connected to the upper part of main body 1, sliding groove 201 is opened in operating arm 2, sliding block 4 is slidably connected in sliding groove 201, telescopic rod 5 is connected between hoop 3 and sliding block 4, specifically, the two ends of telescopic rod 5 are hinged with hoop 3 and sliding block 4, in the embodiment, telescopic rod 5 selects hydraulic damping rod, wedge block 6 is slidably connected in sliding block 4, rack 7 is fixedly connected in sliding groove 201, the inclined surface of wedge block 6 matches the teeth of rack 7.

[0024] The end of wedge block 6 away from rack 7 is fixedly connected with straight rod 8, straight rod 8 is slidably connected with sliding block 4 and operating arm 2, specifically, straight rod 8 can translate left and right in sliding block 4 and operating arm 2.

[0025] The free end of operating arm 2 is provided with cavity 202, L-shaped rod 9 is rotatably connected in cavity 202, fixed rod 10 is fixedly connected to the side of straight rod 8 close to cavity 202, fixed rod 10 is movably connected with the short end of L-shaped rod 9, specifically, the short end of L-shaped rod 9 is provided with sliding groove, one end of fixed rod 10 is located in the sliding groove of L-shaped rod 9, when L-shaped rod 9 rotates, fixed rod 10 can slide and rotate in the sliding groove of L-shaped rod 9, so that straight rod 8 only translates left and right in sliding block 4 and operating arm 2.

[0026] The side of the short end of L-shaped rod 9 close to cavity 202 is slidably connected with arc-shaped guide rail 11, elastic member 12 is arranged in arc-shaped guide rail 11, the two ends of elastic member 12 are connected with the free end of arc-shaped guide rail 11 and operating arm 2 respectively, and elastic member 12 provides a restoring force for L-shaped rod 9.

[0027] The free end of operating arm 2 is fixedly connected with protection rod 13, protection rod 13 is located outside the long end of L-shaped rod 9.

[0028] Working principle: initially, the L-shaped rod 9 is kept away from the cavity 202 of the operating arm 2 under the elastic action of the elastic element 12, so that the straight rod 8 and the wedge block 6 are kept at the right end of the sliding block 4 under the linkage action of the short end of the L-shaped rod 9 and the fixed rod 10, so that the inclined surface of the wedge block 6 is closely engaged with the teeth of the rack 7, effectively limiting the free displacement of the sliding block 4 in the sliding groove 201, and further keeping the current length and state of the telescopic rod 5, ensuring the fixed angle of the operating arm 2 relative to the main body 1, that is, limiting the arbitrary rotation of the operating arm 2. When it is necessary to rotate and adjust the angle of the operating arm 2 to adapt to different working needs, the long end of the L-shaped rod 9 is turned to the side of the cavity 202 of the operating arm 2, and as the L-shaped rod 9 rotates, the elastic element 12 is compressed to provide a restoring force for the L-shaped rod 9. The short end of the L-shaped rod 9 links with the fixed rod 10, driving the straight rod 8 to move left, and further driving the wedge block 6 to move left away from the rack 7, so that the inclined surface of the wedge block 6 gradually moves away from the teeth of the rack 7, thereby releasing the limitation on the displacement of the sliding block 4. At this time, the operating arm 2 can be freely rotated. During the rotation of the operating arm 2, the sliding block 4 freely slides in the sliding groove 201, and the length of the telescopic rod 5 can be adjusted adaptively, thereby ensuring the stability of the rotation process of the operating arm 2. When the adjustment is completed, only the long end of the L-shaped rod 9 needs to be released, so that the L-shaped rod 9 automatically rotates to the side away from the cavity 202 of the operating arm 2 under the elastic action of the elastic element 12, thereby driving the straight rod 8 and the wedge block 6 to move right under the linkage action of the short end of the L-shaped rod 9 and the fixed rod 10. The wedge block 6 is re-engaged with the rack 7 to limit the displacement of the sliding block 4, and further keeps the current angle of the operating arm 2 relative to the main body 1 under the support of the telescopic rod 5, so that the angle adjustment of the operating arm becomes simple and stable.

[0029] In addition, the design of the protective rod 13 not only can increase the overall structural strength of the operating arm 2, but also can prevent the accidental operation of the L-shaped rod 9 from causing harm to the workers, thereby improving the use safety of the drilling machine.

[0030] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
