Description

Technical Field

[0001] The utility model relates to the technical field of air-leg rock drills, in particular to an air-leg rock drill. Background Art

[0002] A rock drill is a tool used to mine rocks. It is widely used in mining, tunnel construction, road construction, geological exploration and other fields. It mainly breaks rocks through high-frequency impact and rotational motion to drill holes or break large rocks. The pneumatic leg rock drill is a pneumatic support leg that is rotated and connected to the lower side of the rock drill. The pneumatic support leg applies supporting pressure to the rock drill, so that the drill bit of the rock drill can press the rock mass to drill holes.

[0003] Most of the existing pneumatic legs are directly hinged on the lower end surface of the rock drill. During the drilling process, the user holds the handle on the rock drill with one hand and the handle on the pneumatic leg with the other hand, so as to control the drilling angle and depth of the rock drill bit. However, in actual application, it is found that the position design of the pneumatic legs is not ergonomic. The user holds the two handles with both hands on both sides of the body, which will cause the body to tilt and make it difficult to face the rock wall to observe the drilling angle. Although the user can hold the two handles to forcibly twist the body to face the rock wall or greatly twist the shoulder of one arm to face the rock wall, fatigue is very likely to occur after working for a long time. For this reason, we propose a pneumatic leg rock drill. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an air-leg rock drill.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a pneumatic leg rock drill, comprising a rock drill body and a pneumatic leg, wherein a first handle is fixedly connected to an end face of the rock drill body away from the drill bit, and a second handle is fixedly connected to the surface of the pneumatic leg, and further comprising:

[0006] An annular connecting block, the annular connecting block is fixedly connected to the lower end surface of the rock drill body;

[0007] A connecting rod, the connecting rod is inserted into the annular connecting block, a connecting ring is fixedly connected to the circumferential surface of the connecting rod, and the connecting ring and the annular connecting block are detachably connected via a plurality of anti-vibration screws;

[0008] A rotating ring is fixedly connected to an end surface of the pneumatic support leg away from the support foot, and the rotating ring is rotatably connected to the circumferential surface of the connecting rod.

[0009] Preferably, an end face of the connecting rod away from the annular connecting block is fixedly connected to a baffle, a circumferential surface of the connecting rod is fixedly connected to a limit ring, and the rotating ring is located between the limit ring and the baffle to limit the movement of the rotating ring along the direction of the connecting rod.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In this solution, the rock drill body and the pneumatic support leg are connected by a horizontal connecting rod, so that the first handle and the second handle are staggered, which makes it convenient for the user to face the rock wall to be excavated with both hands on the left and right sides respectively holding the first handle and the second handle to work, which helps to avoid the user twisting the body or bending the shoulders greatly to face the rock wall, thereby reducing the user's fatigue in accordance with ergonomic design. At the same time, the connecting rod can be set on the other side of the annular connecting block, so that it can be used by both left-handed and right-handed people. The connecting rod and the annular connecting block are connected by multiple shock-proof screws to facilitate the separation and disassembly of the rock drill body and the pneumatic support leg, and it is also helpful to avoid the loosening of the shock-proof screws due to vibration.

[0012] In this solution, since the rock drill body is arranged on one side of the pneumatic support leg, it is convenient for the drill bit of the rock drill body to drill holes in the top rock wall, which is beneficial to avoid the problem of limited rotation angle of the rock drill body and the pneumatic support leg being located in the same plane.

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-Figure 4The pneumatic leg rock drill shown in the figure comprises a rock drill body 1 and a pneumatic leg 9, wherein a first handle 2 is fixedly connected to an end surface of the rock drill body 1 away from the drill bit, and a second handle 10 is fixedly connected to the surface of the pneumatic leg 9, and further comprises:

[0020] An annular connecting block 3, the annular connecting block 3 is fixedly connected to the lower end surface of the rock drill body 1;

[0021] A connecting rod 4 is inserted into the annular connecting block 3. A connecting ring 6 is fixedly connected to the circumferential surface of the connecting rod 4. The connecting ring 6 and the annular connecting block 3 are detachably connected via a plurality of anti-vibration screws 5.

[0022] The rotating ring 7 is fixedly connected to an end surface of the pneumatic support leg 9 away from the support foot, and the rotating ring 7 is rotatably connected to the circumferential surface of the connecting rod 4.

[0023] When the device is used, one end of the connecting rod 4 is inserted into the annular connecting block 3, the connecting rod 4 and the annular connecting block 3 are connected and fixed by the anti-vibration screw 5, and the supporting foot of the pneumatic support leg 9 is placed on the ground. The user holds the first handle 2 with one hand and the second handle 10 with the other hand to open the pneumatic support leg 9 and the rock drill body 1 to drill a hole;

[0024] In this solution, the rock drill body 1 and the pneumatic support leg 9 are connected by a transverse connecting rod 4, so that the first handle 2 and the second handle 10 are placed in a staggered manner, which is convenient for the user to face the rock wall to be excavated with both hands on the left and right sides to hold the first handle 2 and the second handle 10 respectively to work, which is beneficial to avoid the user twisting the body or bending the shoulders to face the rock wall, thereby reducing the user's fatigue in accordance with ergonomic design. At the same time, the connecting rod 4 can be set on the other side of the annular connecting block 3, so that it is convenient for both left-handed and right-handed people to use it. The connecting rod 4 and the annular connecting block 3 are connected by a plurality of shockproof screws 5 to facilitate the separation and disassembly of the rock drill body 1 and the pneumatic support leg 9, and it is also beneficial to avoid the loosening of the shockproof screws 5 caused by vibration;

[0025] In this solution, since the rock drill body 1 is arranged on one side of the pneumatic support leg 9, it is convenient for the drill bit of the rock drill body 1 to drill holes in the top rock wall, which is beneficial to avoid the problem of limited rotation angle of the rock drill body 1 and the pneumatic support leg 9 in the same plane.

[0026] Specifically, a baffle 8 is fixedly connected to one end face of the connecting rod 4 away from the annular connecting block 3, a limiting ring 11 is fixedly connected to the circumferential surface of the connecting rod 4, and the rotating ring 7 is located between the limiting ring 11 and the baffle 8 to limit the movement of the rotating ring 7 along the direction of the connecting rod 4.

[0027] During operation, the rotating ring 7 is limited by the cooperation of the baffle 8 and the limiting ring 11, which helps to prevent the rotating ring 7 from sliding on the surface of the connecting rod 4 due to vibration. At the same time, the distance between the rotating ring 7 and the annular connecting block 3 is controlled within sixty centimeters, which is convenient for the user to hold the first handle 2 and the second handle 10 while avoiding the connecting rod 4 being too long and causing the pneumatic support legs 9 to apply pressure and cause the connecting rod 4 to bend.
