[0049] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0050] like Figure 1-Figure 8 As shown, this embodiment provides a drilling rig with a translational cab, and the drilling rig includes a frame 10, a boom 20, a first connecting rod mechanism 30 and a cab 40.

[0051] The frame 10 is used to provide a mounting reference for the arm 20, and a travel wheel may be provided at the lower portion thereof to facilitate movement.

[0052] The arm 20 can swing relative to the frame 10 to adjust its angle. The cab 40 is hinged to the arm 20 through the first link mechanism 30, so that the cab 40 can be smoothly lifted and moved laterally under the drive of the arm 20. The cab will not deflect during the process.

[0053] The cab 40 is hinged to the boom 20 through the first link mechanism 30, so that the cab 40 can move with the boom 20, and the cab 40 can be lifted and lowered and moved sideways smoothly during the movement, that is, the cab 40 is relatively fixed and does not deflect, so that better comfort and working vision can be obtained. At the same time, the cab 40 installed on the boom 20 will not occupy the space of the frame 10, especially the space at the front end of the frame 10, so that the setting space of the boom 20 is relatively larger. And because there is no need to set up an additional drive structure to drive the cab 40, the manufacturing cost is reduced.

[0054] In some embodiments, the drilling rig includes a slewing mechanism rotatably disposed on the frame 10, and the arm 20 includes a first folding arm 21, which is swingably disposed on the slewing mechanism 50. It can be understood that the arm 20 can rotate with the slewing mechanism 50 and can also swing to adjust its own angle.

[0055] In some embodiments, the first link mechanism 30 includes a first link 31 parallel to the first folding arm 21, the first link 31 has a hinge point hinged to the cab 40 and a hinge point hinged to the slewing mechanism 50, the first folding arm 21 has a hinge point hinged to the cab 40 and a hinge point hinged to the slewing mechanism 50, wherein the four hinge points between the first link 31, the cab 40, the first folding arm 21 and the slewing mechanism 50 are respectively located at the four corners of a parallelogram. In this way, the orientation of the cab 40 remains unchanged during the swinging process.

[0056] It can be understood that the structure of the first link mechanism 30 is not limited.

[0057] In some embodiments, the first link mechanism 30 includes a first link sub-mechanism and a second link sub-mechanism arranged on opposite sides of the width direction of the first folding arm 21. The first link sub-mechanism and the second link sub-mechanism both include a first link 31 and a second link 32, wherein the first end of the first link 31 is hinged to the slewing mechanism 50, the second end of the first link 31 and the first end of the second link 32 are jointly hinged to the cab 40, and the second end of the second link 32 and the cab 40 are jointly hinged to the first folding arm 21.

[0058] The first link mechanism 30 is provided with the first link sub-mechanism and the second link sub-mechanism on opposite sides in the width direction of the first folding arm 21 to enhance the overall strength of the first link mechanism 30 and improve driving safety.

[0059] Wherein, each hinge point of the first connecting rod sub-mechanism and the second connecting rod sub-mechanism is connected through a hinge shaft.

[0060] The first link sub-mechanism and the second link sub-mechanism may be arranged on opposite sides of the first folding arm 21 in the width direction.

[0061] The first connecting rod 31 is located at the back side of the first folding arm 21. Figure 1 In the embodiment, the first connecting rod 31 is located on the left side of the first folding arm 21 .

[0062] In some embodiments, the hinge point where the first connecting rod 31 is hinged to the rotating mechanism 50 is lower in height direction than the hinge point where the first folding arm 21 is hinged to the rotating mechanism 50. In this way, during the swinging process, even if the first folding arm 21 swings backward to a horizontal position, the first connecting rod 31 will not interfere with the first folding arm 21.

[0063] The number of booms 20 on the frame 10 is not limited. In some embodiments, at least two booms 20 are provided along the width direction of the frame 10 to improve the operation efficiency. It is understandable that each boom 20 is provided with a corresponding slewing mechanism 50 so that each boom 20 can operate independently.

[0064] It is understandable that in some embodiments, the booms 20 are provided in two groups, and the cab 40 is distributed between the two groups of the booms 20 and is hinged to one of the groups of the booms 20. In this way, the cab 40 can move with one of the groups of the booms 20, and the view of the cab 40 in the relatively middle position will not be blocked by the two booms 20. Figure 4 In the embodiment, the cab 40 is arranged on a set of arms 20 at the lower side.

[0065] In order to adjust the angle of the arm 20 relative to the frame 10 , in some embodiments, the arm 20 includes a second connecting rod mechanism 22 and a first folding drive assembly 27 .

[0066] The second link mechanism 22 is located on the front side of the first folding arm 21. Figure 1 The second link mechanism 22 includes a third link 221 and a fourth link 222, wherein the first end of the third link 221 is hinged to the first folding arm 21, the first end of the fourth link 222 is hinged to the slewing mechanism 50, and the second end of the third link 221 is hinged to the second end of the fourth link 222 to form a first movable hinge point 221a.

[0067] The first folding drive assembly 27 is located on the front side of the first folding arm 21. Figure 1 The middle is the right side. One end of the first folding drive assembly 27 is hinged to the first movable hinge point 221a. It can be understood that the first folding drive assembly 27 and the second connecting rod mechanism 22 can be provided in multiple groups.

[0068] It can be understood that the first end of the third connecting rod 221 and the hinge point of the first folding arm 21, the first end of the fourth connecting rod 222 and the hinge point of the rotating mechanism 50, the first movable hinge point 221a, and the hinge point of the first folding arm 21 and the rotating mechanism 50 are distributed in a quadrilateral, and are respectively located at the four corners of the above-mentioned quadrilateral.

[0069] In some embodiments, the other end of the first folding drive assembly 27 is hinged to the first folding arm 21. The hinge point between the third link 221 and the first folding arm 21 is the hinge point of the third link 221, and the hinge point of the other end of the first folding drive assembly 27 is located on the side of the hinge point of the third link 221 away from the slewing mechanism 50.

[0070] In some embodiments, the third connecting rod 221 and the fourth connecting rod 222 are both arc-shaped connecting rods, the middle portion of the third connecting rod 221 is bent toward the side away from the rotating mechanism 50 , and the middle portion of the fourth connecting rod 222 is bent toward the side away from the rotating mechanism 50 .

[0071] In some embodiments, the hinge point between the first folding arm 21 and the swivel mechanism 50 is higher than the hinge point between the first end of the fourth connecting rod 222 and the swivel mechanism 50. Specifically, the swivel mechanism 50 includes a rotatable turntable 52, the turntable 52 has a mounting boss, the cross section of the mounting boss is triangular, wherein the first end of the fourth connecting rod 222 is hinged to a first corner of the mounting boss, and the first folding arm 21 is hinged to a second corner of the mounting boss, wherein the height of the second corner is higher than the height of the first corner, and the second corner is located relatively to the rear of the first corner.

[0072] In some embodiments, the arm 20 includes a second folding arm 28 , a third connecting rod mechanism 23 and a second folding driving assembly 29 .

[0073] The second folding arm 28 is hinged to the first folding arm 21. The two can rotate relative to each other with the hinge point as the rotation center.

[0074] The third link mechanism 23 is located on the front side of the first folding arm 21, and includes a fifth link 231 and a sixth link 232. The first end of the fifth link 231 is hinged to the first folding arm 21, the first end of the sixth link 232 is hinged to the second folding arm 28, and the second end of the fifth link 231 is hinged to the second end of the sixth link 232 to form a second movable hinge point 231a.

[0075] The second folding driving assembly 29 is located on the front side of the first folding arm 21 , and one end of the second folding driving assembly 29 is hinged to the second movable hinge point 231 a .

[0076] It can be understood that the angle between the first folding arm 21 and the second folding arm 28 can be adjusted through the third connecting rod mechanism 23 and the second folding drive assembly 29 to control the expansion and folding of the arm frame 20.

[0077] It is understandable that, when unfolded, the height of the arm 20 is determined by the angle of the first folding arm 21 relative to the frame 10, and when the first folding arm 21 is in a vertical state, the height of the arm 20 is the largest. It should be added that, in the stowed state, the unfolding angle of the first folding arm 21 relative to the frame 10 is 0 degrees. When the rotation angle of the first folding arm 21 is greater than 90 degrees, the overall amplitude of the arm 20 increases.

[0078] It can be understood that the hinge point between the first end of the fifth link 231 and the first folding arm 21, the hinge point between the first end of the sixth link 232 and the second folding arm 28, the second movable hinge point 231a, and the hinge point between the first folding arm 21 and the second folding arm 28 are distributed in a quadrilateral, and are respectively located at the four corners of the above-mentioned quadrilateral.

[0079] It can be understood that, in the retracted state, the angle between the first folding arm 21 and the second folding arm 28 is 0 degrees, and in the unfolded state, it can be unfolded to a maximum of 270 degrees. Specifically, the third link 221 and the fourth link 222 of the second link mechanism 22 are both located on the front side of the first folding arm 21, so that when the second folding arm 28 can be folded to 180 degrees and continue to rotate in the backward direction, the third link 221 and the fourth link 222 will not interfere with each other.

[0080] In some embodiments, the fifth connecting rod 231 and the second connecting rod 32 are hinged together on the first folding arm 21. That is to say, the hinge axes of the fifth connecting rod 231 and the second connecting rod 32 coincide with each other.

[0081] In some embodiments, the first folding arm 21 has a straight portion and a bent portion connected to each other, and the second folding arm 28 also has a straight portion and a bent portion connected to each other, and the bent portion of the first folding arm 21 is hinged to the bent portion of the second folding arm 28. In this way, when the first folding arm 21 and the second folding arm 28 are folded to be parallel, the first folding arm 21 and the second folding arm 28 will not interfere with each other.

[0082] It is understandable that in a construction environment with limited space, in order to meet the operating range of the boom 20, the boom 20 is generally longer. An overly long boom 20 makes the entire vehicle excessively long and the turning radius is too large. During tunnel driving, the requirement for rapid turning of the equipment cannot be met, causing driving inconvenience and affecting construction.

[0083] In some embodiments, the boom 20 includes a telescopic arm 24, which is disposed at one end of the second folding arm 28 away from the first folding arm 21, and the telescopic arm 24 can be extended along its length. It can be understood that the use of a folding + telescopic arm 24 structure can increase the coverage of the boom 20, while reducing the overall size in the folded state, thereby improving the passing capacity.

[0084] In some embodiments, the telescopic arm 24 includes a cylinder disposed on the second folding arm 28 and a piston rod movably disposed on the cylinder, and the telescopic end of the telescopic arm 24 is one end of the piston rod. Its extension can compensate for the length, making the whole longer; at the same time, when it is retracted, the smaller the length, the better the passability of the drilling rig.

[0085] In some embodiments, the arm 20 includes a double swivel mechanism 25 and a propulsion mechanism 26. The double swivel mechanism 25 is disposed at the telescopic end of the telescopic arm 24. The propulsion mechanism 26 is disposed on the double swivel mechanism 25, and the propulsion mechanism 26 can rotate in a horizontal plane or a vertical plane under the drive of the double swivel mechanism 25. In this way, the telescopic arm 24 can rotate in both a horizontal plane and a vertical plane, and its flexibility is greatly improved, which is convenient for the rock drill to drive the drill rod to perform long-distance rock drilling operations.

[0086] It is understandable that a rock drill, a drill rod, etc. are installed on the propulsion mechanism 26, and the rock drill performs rock drilling operations under the action of the propulsion hydraulic cylinder of the propulsion mechanism 26. Therefore, a large range of construction movements can be performed under the action of the double rotary mechanism 25 and the propulsion mechanism 26, thereby improving the applicability of construction. It is understandable that the above-mentioned double rotary mechanism 25 and the propulsion mechanism 26 are prior arts. The specific structure thereof can be referred to CN206942663U.

[0087] It is understandable that the structure of the slewing mechanism 50 is not limited. In some embodiments, the slewing mechanism 50 includes a slewing drive hydraulic cylinder 51 and a slewing table 52 that can be extended and retracted along its length direction, the slewing table 52 has a first hinge point 51a that deviates from the axis of rotation, the first end of the slewing drive hydraulic cylinder 51 is hinged to the frame 10, and the second end is hinged to the first hinge point 51a of the slewing table 52, and the slewing drive hydraulic cylinder 51 can be extended and retracted to drive the slewing table 52 to rotate relative to the frame 10.

[0088] By hingedly connecting the slewing driving hydraulic cylinder 51 to the first hinge point 51a which is offset from the slewing axis of the slewing platform 52, the slewing driving hydraulic cylinder 51 can drive the slewing platform 52 to rotate when the slewing driving hydraulic cylinder 51 is extended or retracted. Compared with the existing slewing mechanism 50, the required size in the width direction of the frame 10 is relatively small, so the space occupied in the width direction of the frame 10 can be significantly reduced.

[0089] In some embodiments, a copper sleeve or rolling bearing is disposed between the turntable 52 and the frame 10 to achieve a rotatable connection. Specifically, the frame 10 has a central axis, the turntable 22 is sleeved on the central axis, and the copper sleeve is disposed between the central axis and the turntable 22.

[0090] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
