[0046] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0047] Example
[0048] like Figures 1 to 3 The arm structure of a mining tunneling drill and a specific embodiment of a tunneling rock drilling device shown in the figure are suitable for supporting and adjusting a working mechanism 3, wherein the working mechanism 3 can be a rock drilling mechanism, including:
[0049] The boom base 1 is fixed on the tunneling drilling vehicle on one side and has a support arm 2 hinged on the other side;
[0050] The first adjusting component has one end hinged to the side of the arm seat 1 close to the support arm 2, and the other end hinged to the end of the support arm 2 away from the arm seat 1. The first adjusting component is suitable for pitch and yaw adjustment of the support arm 2; specifically, the first adjusting component may include two telescopic cylinders, one of which is hinged between the arm seat 1 located below the support arm 2 and the end of the support arm 2 away from the arm seat 1, thereby playing a role in pitch adjustment of the support arm 2, and the other telescopic cylinder can be hinged between the arm seat 1 located on the left or right side of the support arm 2 and the end of the support arm 2 away from the arm seat 1, thereby playing a role in swing adjustment of the support arm 2.
[0051] a second adjusting component, one end of which is fixedly connected to the first adjusting component;
[0052] The third adjustment component is hinged to the other end of the second adjustment component. The third adjustment component is provided with a working mechanism 3. The second adjustment component is suitable for performing telescopic, pitch and yaw adjustments on the third adjustment component. The third adjustment component is suitable for performing rotation and pitch adjustments on the working mechanism 3.
[0053] Among them, pitch, swing and rotation adjustments can be collectively referred to as angle adjustment.
[0054] Specifically, the second adjustment component may include a telescopic arm 5 hinged at one end to the support arm 2 and two telescopic cylinders. The other end of the telescopic arm 5 is connected to the third adjustment component, one of the telescopic cylinders is hinged between the support arm 2 located below the telescopic arm 5 and the end of the telescopic arm 5 away from the arm support seat 1, thereby adjusting the pitch of the telescopic arm 5, and thus adjusting the pitch of the third adjustment component. The other telescopic cylinder can be hinged between the support arm 2 located on the left or right side of the telescopic arm 5 and the end of the telescopic arm 5 away from the arm support seat 1, thereby adjusting the swing of the telescopic arm 5, and thus adjusting the swing of the third adjustment component.
[0055] The support arm 2 can support the second adjustment component, the third adjustment component and the working mechanism 3. The first adjustment component can support the support arm 2 and can also adjust the pitch and swing of the support arm 2. The second adjustment component can perform telescopic, pitch and yaw adjustments on the third adjustment component. The third adjustment component can perform rotation and pitch adjustments on the working mechanism 3. This application uses multiple groups of angle adjustment components to cooperate with telescopic components to make the adjustment of the working mechanism 3 more precise.
[0056] Furthermore, the first adjustment component includes:
[0057] There are two first telescopic cylinders 4, one end of each of the first telescopic cylinders 4 is hinged to the side of the arm support seat 1 close to the support arm 2, and the other end of the first telescopic cylinder 4 is hinged to the end of the support arm 2 away from the arm support seat 1; the synchronous extension and retraction of the two first telescopic cylinders 4 can adjust the pitch of the support arm 2, and the asynchronous extension and retraction of the two first telescopic cylinders 4 can adjust the swing of the support arm 2. It should be noted that when the two first telescopic cylinders 4 are in an asynchronous state, if the pitch adjustment is continued, the first telescopic cylinders 4 need to be adjusted according to the actual situation, and at this time, the adjustment of the two first telescopic cylinders 4 is asynchronous.
[0058] At least one of the hinges of the first telescopic cylinder 4 at the boom seat 1 and the hinge of the first telescopic cylinder 4 at the support arm 2 has two hinge points, and the hinge points of the two hinges can be located in the same plane; in this embodiment, both hinges have two hinge points, and the four hinge points are located in the same plane, but this embodiment is not limited to this.
[0059] The line connecting the hinge point between the support arm 2 and the boom mount 1 and the hinge point between the support arm 2 and the first telescopic cylinder 4 is not located within the plane formed by the hinge point between the first telescopic cylinder 4 and the boom mount 1 and the hinge point between the support arm 2 and the first telescopic cylinder 4. It should be noted that the pitch movement trajectory of the support arm 2 is a circle. If the line connecting the hinge point between the support arm 2 and the boom mount 1 and the hinge point between the support arm 2 and the first telescopic cylinder 4 is located within the plane formed by the hinge point between the first telescopic cylinder 4 and the boom mount 1 and the hinge point between the support arm 2 and the first telescopic cylinder 4, interference will occur between the telescopic movement of the first telescopic cylinder and the support arm 2, making it impossible to adjust the pitch of the support arm 2. In this embodiment, the hinge point between the support arm 2 and the boom mount 1 is located above the two hinge points between the first telescopic cylinder 4 and the boom mount 1. The hinge point between the support arm 2 and the boom mount 1, the hinge point between any one of the first telescopic cylinders 4 and the boom mount 1, and the hinge point between any one of the support arm 2 and the first telescopic cylinder 4 form a triangle.
[0060] Furthermore, when the two first telescopic cylinders 4 are at the same telescopic length, the support arm 2 is located on the symmetrical plane of the two first telescopic cylinders 4, which can facilitate the adjustment of the pitch and yaw of the support arm 2 and also make the force on the two first telescopic cylinders 4 more uniform.
[0061] Furthermore, the second adjustment component includes:
[0062] The telescopic arm 5 has one end fixedly connected to the end of the support arm 2 away from the boom base 1, and the other end hingedly connected to the third adjustment assembly. The telescopic arm 5 can be a telescopic cylinder or a telescopic motor, but this embodiment is not limited thereto. Furthermore, the first telescopic oil cylinder 4 can be directly hingedly connected to the end of the telescopic arm 5 near the boom base 1, replacing the hinged connection between the first telescopic oil cylinder 4 and the support arm 2.
[0063] The connecting sleeve 6 is sleeved on the telescopic arm 5, and one end of the connecting sleeve 6 is fixedly connected to the end of the telescopic arm 5 away from the support arm 2; the connecting sleeve 6 can move as the telescopic arm 5 extends and retracts.
[0064] There are two second telescopic oil cylinders 7, one end of which is hinged to the connecting sleeve 6, and the other end is hinged to the third adjustment component;
[0065] At least one of the hinges of the second telescopic cylinder 7 at the connecting sleeve 6 and the hinge of the second telescopic cylinder 7 at the third adjusting assembly has two hinge points, and the hinge points of the two hinges are located in the same plane; in this embodiment, both hinges have two hinge points, and the two second telescopic cylinders 7 are arranged above the connecting sleeve 6, that is, the two second telescopic cylinders 7 are located above the telescopic arm 5.
[0066] The line connecting the second telescopic cylinder 7 from the hinge point of the connecting sleeve 6 to the hinge point of the telescopic arm 5 and the third adjustment assembly is not located in the plane formed by the hinge points of the second telescopic cylinder 7 and the connecting sleeve 6 and the hinge points of the second telescopic cylinder 7 and the third adjustment assembly. This ensures that when the two second telescopic cylinders 7 are synchronously extended and retracted, they can achieve pitch adjustment of the third adjustment assembly.
[0067] It should be noted that the pitch movement trajectory of the third adjustment assembly is a circle. If the line connecting the second telescopic cylinder 7 from the hinge point of the connecting sleeve 6 to the hinge point of the telescopic arm 5 and the third adjustment assembly is located on the plane formed by the hinge points of the second telescopic cylinder 7 and the connecting sleeve 6 and the third adjustment assembly, the extension and retraction of the second telescopic cylinder will interfere with the connecting sleeve 6 and the third adjustment assembly, respectively, making it impossible to adjust the pitch of the third adjustment assembly. In this embodiment, the second telescopic cylinders 7 are arranged above the connecting sleeve 6, that is, the two second telescopic cylinders 7 are located above the telescopic arm 5, and any second telescopic cylinder 7 forms a triangle at the hinge point of the connecting sleeve 6, the hinge point of the telescopic arm 5 and the third adjustment assembly, and the hinge point of any second telescopic cylinder 7 and the third adjustment assembly.
[0068] The telescopic arm 5 adjusts the telescopic position of the third adjustment assembly, thereby adjusting the relative position between the working mechanism 3 and the rock. Driven by the connecting sleeve 6, the second telescopic cylinder 7 adjusts the telescopic position along with the telescopic arm 5. Synchronous extension and retraction of the second telescopic cylinder 7 adjusts the pitch of the third adjustment assembly, while asynchronous extension and retraction of the second telescopic cylinder 7 adjusts the swing of the third adjustment assembly.
[0069] Furthermore, when the two second telescopic cylinders 7 are at the same telescopic length, the telescopic arm 5 is located on the symmetric plane of the two second telescopic cylinders 7. This facilitates adjustment of the pitch and yaw of the third adjustment assembly and makes the force on the two second telescopic cylinders 7 more uniform.
[0070] Furthermore, the third adjustment component includes:
[0071] The swing cylinder 8 has one end hinged to the telescopic arm 5 and the two second telescopic cylinders 7;
[0072] One end of the connecting frame 9 is fixedly arranged on the swing cylinder 8 away from the end of the telescopic arm 5.
[0073] It should be noted that a connecting member 12 may be provided on the swing cylinder 8 , one side of the connecting member 12 is fixedly connected to the swing cylinder 8 , and the other side is hinged to the telescopic arm 5 and the two second telescopic cylinders 7 .
[0074] Furthermore, the third adjustment component further includes:
[0075] A support frame 10 is mounted on the connecting frame 9 at the end away from the swing cylinder 8. The side of the support frame 10 near the swing cylinder 8 is hingedly connected to the end of the connecting frame 9 away from the swing cylinder 8. A third telescopic cylinder 11 is hingedly connected between the side of the support frame 10 near the swing cylinder 8 and the side wall of the connecting frame 9. The swing cylinder 8 drives the connecting frame 9 to rotate. The extension and retraction of the third telescopic cylinder 11 adjusts the pitch of the support frame 10, and thus the pitch of the working mechanism 3.
[0076] Furthermore, the working mechanism 3 is fixedly arranged on a side of the support frame 10 away from the swing cylinder 8 .
[0077] A tunneling and rock drilling device, comprising:
[0078] Head drilling rig;
[0079] and the boom structure as described above;
[0080] The boom seat 1 in the boom structure is arranged on the tunneling drilling vehicle.
[0081] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
