Description

Technical Field

[0001] The present invention relates to the field of engineering machinery, and in particular to a rock drilling vehicle base and a rock drilling vehicle. Background Art

[0002] The rock drill is a rock drilling machine used for drilling and blasting construction of tunnels and underground projects. It is an important equipment for excavating lanes and tunnels in underground mines, hydropower, railways, highways and other fields. When the rock drill is in operation, the drill arm changes amplitude to the left, right, up and down, and performs telescopic, rotational and swinging movements. The center of mass position is constantly changing. At the same time, the impact force directly acts on the bottom of the hole, and the drill arm is subjected to a strong reaction force. The base of the rock drill connects the frame and the drill arm. As the main structural component supporting the operation of the drill arm, the base of the rock drill endangers the safety of people and machines if it is not strong enough, and affects the drilling positioning speed and accuracy if it is not rigid enough. In recent years, the application scope of rock drills has been continuously expanded, and the operating conditions are harsh, and the requirements for the strength and rigidity of the base have been continuously improved.

[0003] The inventors found that there are at least the following problems in the prior art: In the related art, the base structure used by the rock drill is a box-type structure, the reinforcing ribs and the box-type ribs are arranged in an unreasonable position, there are many welds, they are easy to deform, and the welds in the intersection area of ​​the back plate and shell are subjected to large bending moments and are prone to cracking. Especially when the construction operation is to extend the drill arm to the longest position to perform vertical upward anchoring, the base structure is subjected to a large bending moment. The prior art solution increases the weight by increasing the thickness of the rib plate; and when welding thick plates, the welding performance at the intersection of multiple plates and shells is poor, and it is easy to crack under the action of large bending moments.

[0065] See also Figure 4 and Figure 7 In some embodiments, the top of the first bending plate 31 is narrower than its bottom, that is, in the width direction of the drilling vehicle base 3, the width of the top of the first bending plate 31 is smaller than the width of the bottom of the first bending plate 31. The first bending plate 31 includes a first straight section 311 and a first bending section 312. There are two connecting side surfaces between the top and the bottom of the first straight section 311.

See Figure 7 The width of the top and bottom of the second bending section is substantially the same, and the second bending section as a whole is bent in a direction away from the second connecting plate 39. The second bending section 322 and the second straight section 321 can be integrated, and the bottom of a plate is bent to obtain the second bent plate 32.

[0067] See also Figure 4 and Figure 6 In some embodiments, the first connecting plate 33 is constructed to be symmetrical, and the first bending plate 31 and the second bending plate 32 are arranged symmetrically with respect to the center line of the length direction of the first connecting plate 33. The first connecting plate 33 can be a flat plate. Specifically, the first connecting plate 33 is installed between the first bending plate 31 and the second bending plate 32, one end of the first connecting plate 33 is fixedly connected to the first straight section 311 of the first bending plate 31, specifically, for example, by welding, and the other end of the first connecting plate 33 is fixedly connected to the second straight section 321 of the second bending plate 32, specifically, for example, by welding.

[0068] See also Figure 1 The first connecting plate 33 is used to install the boom mounting seat (not shown in the figure). Specifically, the first connecting plate 33 is provided with a first connecting hole 331, and the first connecting hole 331 is, for example, a threaded hole. The first connecting holes 331 are arranged along the edge of the first connecting plate 33. Specifically, the first connecting holes 331 are provided at the top and both ends of the length direction of the first connecting plate 33. The boom mounting seat is fixedly installed on the first connecting plate 33 through the first connecting hole 331, and the boom 2 is installed to the boom mounting seat in a cantilever manner. A joist 4 is installed at the free end of the boom 2.

[0069] Continue to see Figures 2 to 4In some embodiments, the rock drilling vehicle base 3 further includes a top plate 34, which is arranged between the first bending plate 31 and the second bending plate 32. The top plate 34 is also located on the top of the first connecting plate 33; the top plate 34 is perpendicular to the first bending plate 31, the second bending plate 32 and the first connecting plate 33, and is fixedly connected. The top plate 34 is specifically a flat plate, and the top plate 34 plays a role in enhancing the structural stability of the rock drilling vehicle base 3.

[0070] See also Figures 2 to 4 In some embodiments, the rock drilling vehicle base 3 further includes a bottom plate 35, which is specifically a flat plate. The bottom plate 35 is arranged between the first bending plate 31 and the second bending plate 32; the bottom plate 35 is also located at the bottom of the first connecting plate 33; the top plate 34 is perpendicular to the first bending plate 31, the second bending plate 32 and the first connecting plate 33, and is fixedly connected; the bottom plate 35 is arranged at intervals from the top plate 34, and the first connecting plate 33 is located between the top plate 34 and the bottom plate 35.

[0071] The first bending plate 31, the second bending plate 32, the first connecting plate 33, the top plate 34 and the bottom plate 35 together form a door shape, which effectively ensures the bending stability and structural rigidity of the base structure, improves the welding strength between the first connecting plate 33 and its connecting parts, and improves the fatigue resistance of the rock drilling vehicle base 3.

[0072] Continue to see Figure 3 and Figure 4 In some embodiments, the rock drilling vehicle base 3 further includes a first reinforcing plate 36, and the number of the first reinforcing plates 36 is one or more. The multiple first reinforcing plates 36 are dispersedly arranged; each first reinforcing plate 36 is fixed between the top plate 34 and the bottom plate 35. The first reinforcing plates 36 enhance the local structural rigidity of the rock drilling vehicle base 3, so that the rock drilling vehicle base 3 has higher strength and stronger bearing capacity.

[0073] See also Figures 3 to 5 In some embodiments, in the width direction of the rock drilling vehicle base 3, the top of the first reinforcing plate 36 is narrower than its bottom. The first reinforcing plate 36 adopts a triangular structure with a small top size and a large bottom size. On the one hand, the first reinforcing plate 36, the first connecting plate 33, and the bottom plate 35 together form a triangular structure, which improves the local strength of the rock drilling vehicle base 3, improves the structural rigidity, improves the fatigue reliability, and improves the bearing capacity of the rock drilling vehicle base 3; on the other hand, it also makes the first reinforcing plate 36 easy to process and manufacture, and also easy to connect and fix with the first connecting plate 33 and the bottom plate 35.

[0074] See also Figures 3 to 5In order to further reduce the weight of the rock drilling vehicle base 3, the first reinforcing plate 36 is provided with a weight-reducing hole 361, and the opening size of the weight-reducing hole 361 at the top of the first reinforcing plate 36 is smaller than the opening size of the weight-reducing hole 361 at the bottom of the first reinforcing plate 36. With the weight-reducing hole 361 of the above structure, the opening size of the weight-reducing hole 361 is very large, and the weight-reducing of the rock drilling vehicle base 3 is reduced as much as possible while ensuring the bearing capacity of the rock drilling vehicle base 3.

[0075] Continue to see Figure 4 and Figure 5 In some embodiments, the rock drilling vehicle base 3 further includes a second reinforcing plate 37 and a third reinforcing plate 38.

Figure 5 The two ends of the second reinforcing plate 37 extend downward, and the middle part is concave. The second reinforcing plate 37 and the third reinforcing plate 38 are arranged vertically, so that the local bearing performance of the rock drilling vehicle base 3 is stronger.

[0077] The first reinforcing plate 36 , the second reinforcing plate 37 , and the third reinforcing plate 38 all serve to increase the local stiffness of the rock drilling vehicle base 3 . The first reinforcing plate 36 , the second reinforcing plate 37 , and the third reinforcing plate 38 are all fixedly connected to the bottom plate 35 , and together constitute a supporting structure to improve the local structural stiffness of the rock drilling vehicle base 3 .

[0078] Back to Figure 3 and Figure 4 In some embodiments, the rock drilling vehicle base 3 further includes a second connecting plate 39 and a third connecting plate 310.

[0079] The third connecting plate 310 is provided with a third connecting hole 310a for connecting with the frame 1. Specifically, for example, two rows of third connecting holes 310a are provided, and by selecting the connected second connecting holes 391, the position of the rock drilling vehicle base 3 relative to the frame 1 can be changed to meet the installation requirements.

[0080] The second connecting plate 39 is fixed to the bottom of the first bending section 312; the second connecting plate 39 is perpendicular to the first straight section 311 and the first connecting plate 33. The third connecting plate 310 is fixed to the bottom of the second bending section 322; the third connecting plate 310 is perpendicular to the second straight section 321 and the third connecting plate 310. There is a gap between the second connecting plate 39 and the third connecting plate 310 and the bottom of the first connecting plate 33.

[0081] In some embodiments, the second connecting plate 39 is parallel to the first connecting plate 33, and the two are staggered with each other in the length direction of the rock drilling vehicle base 3. The first connecting plate 33 is located at a relatively high position, and the second connecting plate 39 is located at a relatively low position.

[0082] See also Figure 4 In some embodiments, the third connecting plate 310 is parallel to the first connecting plate 33 and the two are staggered with each other. The first connecting plate 33 is located at a relatively high position, and the third connecting plate 310 is located at a relatively low position.

[0083] The rock drill base 3 is provided with a hollow portion at the middle of the bottom in the length direction to avoid other components of the rock drill.

[0084] The bottom surfaces of the second connecting plate 39 and the first connecting plate 33 are located on the same plane, so that the rock drilling vehicle base 3 is more stable after being installed on the vehicle frame 1.

[0085] The rock drill base 3 provided by the above technical solution is obtained through topological optimization design. The structural layout design of the rock drill base 3 is conducive to improving the rigidity and strength of the rock drill base 3 structure, and improving the stability of the drill arm operation; the structural layout is conducive to improving the weld strength of the base structure and improving the fatigue reliability of the base structure. At the same time, the solution not only ensures the bending resistance of the structure, but also helps to make the structure lightweight, effectively balancing the two conflicting requirements of increasing the strength of the rock drill base 3 structure and achieving lightweight.
