In this embodiment, the rotating seat 22 is connected to the connecting seat 21 through the pivoting support 25, the inner ring of the pivoting support 25 is fixedly connected to the connecting seat 21, and the outer ring of the pivoting support 25 is fixedly connected to the rotating seat 22.

In a non-limiting example, as shown in fig. 2, the connecting base 21 is slidably connected to the base 10, the base 10 is provided with a slide rail 11 for sliding the connecting base 21, the telescopic member 31 is a hydraulic cylinder, one end of the hydraulic cylinder is connected to the connecting base 21, the other end of the hydraulic cylinder is connected to the base 10, and the extension or contraction of the hydraulic cylinder will move the connecting base 21 in the transverse direction a relative to the base 10.
In this embodiment, as shown in fig. 3, the driving mechanism 30 further includes a driving member 32, the telescopic member 31 includes at least two telescopic joints 311, each two adjacent telescopic joints 311 are a first telescopic joint 312 and a second telescopic joint 313, the first telescopic joint 312 and the second telescopic joint 313 are connected by the driving member 32, and the driving member 32 is configured to drive the first telescopic joint 312 and the second telescopic joint 313 to move relatively.

The number of the expansion joints 311 in the expansion member 31 may be two, or may be two or more. In a non-limiting example, the number of the telescopic joints 311 of the telescopic member 31 is three, and the number of the driving members 32 is two because every two adjacent telescopic joints 311 are connected by one driving member 32. The driving part 32 is a hydraulic cylinder, every two adjacent telescopic parts 31 are connected through one hydraulic cylinder, when the hydraulic cylinder extends, the two telescopic parts 31 connected with the hydraulic cylinder are far away from each other, and when the hydraulic cylinder shortens, the two telescopic parts 31 connected with the hydraulic cylinder are close to each other.

The second telescopic joint 313 is movably sleeved outside the first telescopic joint 312, that is, the cross-sectional size of each telescopic joint 311 in the telescopic member 31 is gradually increased in the telescopic direction from the base 10 to the connecting seat 21 of the telescopic member 31, so that the telescopic range of the telescopic member 31 can be effectively increased, and each telescopic joint 311 in the telescopic process of the telescopic member 31 has good stability.

If the length of the first telescopic joint 312 is greater than that of the second telescopic joint 313, that is, the length of each telescopic joint 311 in the telescopic member 31 increases gradually in the telescopic direction from the base 10 to the connecting seat 21 of the telescopic member 31, the first telescopic joint 312 can be partially accommodated in the second telescopic joint 313 under the action of the driving member 32; if the length of the first telescopic joint 312 is smaller than that of the second telescopic joint 313, that is, the length of each telescopic joint 311 in the telescopic member 31 gradually decreases in the telescopic direction from the base 10 to the connecting seat 21, the first telescopic joint 312 can be completely accommodated in the second telescopic joint 313 by the driving member 32.

The first telescopic joint 312 of each adjacent two telescopic joints 311 may be partially received in the second telescopic joint 313, or the first telescopic joint 312 may be completely received in the second telescopic joint 313, depending on the lengths of the first telescopic joint 312 and the second telescopic joint 313. If the length of the first telescopic joint 312 is greater than that of the second telescopic joint 313, that is, the length of each telescopic joint 311 in the telescopic member 31 gradually decreases in the telescopic direction from the base 10 to the connecting seat 21 of the telescopic member 31, the first telescopic joint 312 can be partially accommodated in the second telescopic joint 313 under the action of the driving member 32; if the length of the first telescopic joint 312 is smaller than that of the second telescopic joint 313, that is, the length of each telescopic joint 311 in the telescopic member 31 is gradually increased in the telescopic direction from the base 10 to the connecting base 21, the first telescopic joint 312 can be completely accommodated in the second telescopic joint 313 by the driving member 32.
Of course, the arrangement of the telescopic sections 311 in the telescopic member 31 is not limited to the way in which the cross section of the telescopic section 311 is gradually increased or decreased. In other embodiments, each telescopic joint 311 in the telescopic member 31 may be arranged in other manners, for example, as shown in fig. 6, when the number of the telescopic joints 311 in the telescopic member 31 is three or more, the cross section of the telescopic joint 311 at two ends of three adjacent telescopic joints 311 is larger than that of the telescopic joint 311 in the middle, that is, the telescopic joints 311 at two ends are movably sleeved outside the telescopic joint 311 in the middle.
In this embodiment, as shown in fig. 7, the cross section of the telescopic joint 311 is a hollow rectangular structure, and the outer contour of the cross section of the first telescopic joint 312 matches the inner contour of the cross section of the second telescopic joint 313. This structure makes each telescopic joint 311 only move directionally, so that the telescopic member 31 has better directional telescopic capability. In addition, the cross section of the telescopic joint 311 is a hollow rectangular structure, which can improve the bending strength and the torsional strength of the telescopic joint 311, so that the whole telescopic member 31 has good bending resistance and torsional strength.

For convenience of description, the two driving mechanisms 30 are defined as a first driving mechanism 301 and a second driving mechanism 302, respectively.
In the present embodiment, as shown in fig. 8, the telescopic member 31 in the first driving mechanism 301 is configured to be elongated in the positive direction of the transverse direction a to move the actuator 20 corresponding to the first driving mechanism 301 in a direction away from the actuator 20 corresponding to the second driving mechanism 302; the telescopic member 31 in the second driving mechanism 302 is configured to elongate in the direction opposite to the transverse direction a to move the actuator 20 corresponding to the second driving mechanism 302 in a direction away from the actuator 20 corresponding to the first driving mechanism 301. That is, the extension direction of the telescopic member 31 in the first driving mechanism 301 is opposite to the extension direction of the telescopic member 31 in the second driving mechanism 302, so that the two telescopic members 31 can extend to both sides of the transverse direction a, and when the two telescopic members 31 extend to both sides of the transverse direction a at the same time, the two actuators 20 will move to the opposite directions at the same time, thereby increasing the drilling operation range of the whole drill carriage actuator 100.
Of course, in other embodiments, the extension direction of the telescopic member 31 in the first driving mechanism 301 and the extension direction of the telescopic member 31 in the second driving mechanism 302 may be the same, and when two telescopic members 31 are extended simultaneously, the two actuators 20 will move to the same direction at the same time.
Further, in the present embodiment, the extensible member 31 in the first driving mechanism 301 partially or completely overlaps with the extensible member 31 in the second driving mechanism 302 in the transverse direction a in the shortened state. This configuration allows the overall length of the two telescopic elements 31 in the transverse direction a to be small in the shortened state, without taking up too much space.
It should be noted that the telescopic member 31 is in the shortened state, that is, the telescopic member 31 is in the shortest state during the shortening process. As shown in fig. 8 and 9, when the cross section of the telescopic joint 311 of the telescopic member 31 is gradually increased, the telescopic joint 311 with the largest cross section is connected with the base 10, the telescopic joint 311 with the smallest cross section is connected with the connecting seat 21, and the length of the telescopic joint 311 is gradually decreased in the telescopic direction from the base 10 to the connecting seat 21 of the telescopic member 31, the telescopic member 31 is in the shortened state, that is, the telescopic joints 311 except for the telescopic joint connected with the base 10 in the telescopic member 31 are all located in the telescopic joint 311 with the longest length, and the length of the telescopic member 31 in the shortened state is the length of the telescopic joint 311 with the longest length. The telescopic members 31 in the first driving mechanism 301 partially or completely overlap with the telescopic members 31 in the second driving mechanism 302 in the shortened state in the transverse direction a in the shortened state, i.e. the two longest telescopic joints 311 of the two telescopic members 31 partially or completely overlap in the transverse direction a. Fig. 9 shows a case where the extensible member 31 of the first drive mechanism 301 in the shortened state and the extensible member 31 of the second drive mechanism 302 in the shortened state are all overlapped.

As shown in fig. 10, the present embodiment provides an anchor rod drill carriage 200, which includes a running gear 210 and the drill carriage actuator 100 in the above embodiment, and the base body 10 is connected with the running gear 210.
Optionally, the running gear 210 includes a chassis 211 and a crawler belt 212 disposed at the bottom of the chassis 211, and the running gear 210 runs through the crawler belt 212.
The walking device 210 has a transverse direction a, a longitudinal direction B, and a vertical direction C, and the walking direction of the walking device 210 is the longitudinal direction B.
It can be understood that when the walking device 210 is placed in a horizontal plane, the transverse direction a and the longitudinal direction B are two directions perpendicular to each other in the horizontal plane, and the vertical direction C is a direction perpendicular to the horizontal plane. The transverse direction a of the drill carriage actuator 100 is the transverse direction a of the running gear 210, the longitudinal direction B of the drill carriage actuator 100 is the longitudinal direction B of the running gear 210, and the vertical direction C of the drill carriage actuator 100 is the vertical direction C of the running gear 210.
The base body 10 is connected with the running gear 210, and the base body 10 can be directly connected with the running gear 210, that is, the base body 10 is directly fixed on the chassis 211 of the running gear 210, of course, the base body 10 can also be indirectly connected with the running gear 210 through an intermediate member.
In this embodiment, the anchor rod drilling rig 200 further includes a top bracing device 220, the base 10 is connected with the walking device 210 through the top bracing device 220, and the top bracing device 220 is configured to drive the drill rig actuator 100 to move in the vertical direction C relative to the walking device 210. The vertical C position of the drill carriage actuator 100 can be adjusted by the jacking device 220, and then the vertical C position of the power head 23 is adjusted, and the vertical C operating range of the anchor drill carriage 200 is increased.
The jacking device 220 may be of various configurations as long as the height position of the drill carriage actuator 100 can be changed. In one non-limiting example, the jacking device 220 is a hydraulic cylinder, and the drill carriage actuator 100 is driven to move in the vertical direction C as a whole by the extension or contraction of the hydraulic cylinder.
In this embodiment, as shown in fig. 11, an operation platform 12 is provided on the base 10, and the operation platform 12 is fixed to the base 10. The top bracing apparatus 220 includes a top bracing mechanism 221, a first top bracing member 222, and a second top bracing member 223. The top supporting mechanism 221 includes a first link 2211, a second link 2212, a third link 213, and a fourth link 2214, the first link 2211, the second link 2212, the third link 213, and the fourth link 2214 are sequentially hinged end to form a planar four-link mechanism, the first link 2211 is fixedly connected to the traveling device 210, and the base 10 is hinged to the third link 213. One end of the first support member 222 is hinged to the walking device 210, the other end of the first support member 222 is hinged to the second link 2212, and the first support member 222 is configured to drive the second link 2212 to rotate relative to the first link 2211. One end of the second support member 223 is hinged to the walking device 210, the other end of the second support member 223 is hinged to the base 10, and the second support member 223 is configured to drive the base 10 to rotate relative to the third connecting rod 213, so that the operation platform 12 is located in a horizontal position.
Alternatively, the first link 2211 is fixedly connected to the chassis 211 of the walking device 210.
Optionally, the first top support 222 is a hydraulic cylinder, one end of the hydraulic cylinder is hinged to the chassis 211 of the walking device 210, and the other end of the hydraulic cylinder is hinged to the second connecting rod 2212; the second supporting member 223 is also a hydraulic cylinder, one end of which is hinged to the chassis 211 of the running gear 210, and the other end of which is hinged to the base 10.
It should be noted that the second top support 223 may be one or more (including two). In this embodiment, the number of the second top supports 223 is two, and the hinge axis of the third link 213 and the base 10 in the longitudinal direction B is located between the two second top supports 223. During the period when the first top support 222 is not working and leveling the operation platform 12, when one second top support 223 is extended, the other second top support 223 will be shortened.
The operation platform 12 is used for supporting an operator, namely the operator can stand on the operation platform 12 to carry out operation control on the drill carriage; because the top support mechanism 221 is a planar four-bar linkage, when the first top support 222 drives the second connecting bar 2212 to rotate relative to the first connecting bar 2211, the third connecting bar 213 hinged to the base 10 will make planar motion, the third connecting bar 213 will support the base 10, the operating platform 12 will rise along with the base 10, and in this process, the second top support 223 will work to keep the operating platform 12 at a position parallel to the walking device 210; when the walking device 210 walks on the inclined surface, the walking device 210 and the operation platform 12 will be in an inclined state, and at this time, the second top support member 223 is operated again to rotate the base body 10 relative to the third link 213, so that the operation platform 12 is in a horizontal position to ensure that the operator standing on the operation platform 12 can keep balance.
Understandably, since the first link 2211, the second link 2212, the third link 213 and the fourth link 2214 are sequentially hinged to form a planar four-bar linkage, the hinge axes of the first link 2211 and the second link 2212 are parallel to the hinge axes of the second link 2212 and the third link 213, parallel to the hinge axes of the third link 213 and the fourth link 2214, and parallel to the hinge axes of the fourth link 2214 and the first link 2211, that is, the arrangement directions of the respective hinge axes are consistent.
The hinge axes of the first and second links 2211 and 2212 may be arranged in multiple directions within a horizontal plane, i.e., the hinge axes of the first and second links 2211 and 2212 may be arranged in the transverse direction a, the longitudinal direction B, or other directions within the horizontal plane.
As shown in fig. 12, in the present embodiment, the hinge axes of the first and second links 2211 and 2212 are arranged in the transverse direction a. The anchor drill rig 200 further comprises a support mechanism 230, the operation platform 12 and the running gear 210 being connected by the support mechanism 230, the support mechanism 230 being configured to allow the operation platform 12 to follow the basic body 10 for movement in the vertical direction C and the longitudinal direction B, the support mechanism 230 being configured to prevent the operation platform 12 from rotating about an axis arranged in the longitudinal direction B. The support mechanism 230 is configured not to affect the vertical C and longitudinal B movements of the operation platform 12, and the support mechanism 230 can prevent the operation platform 12 from rotating around the axis arranged along the longitudinal B, that is, the support mechanism 230 has an effect of preventing the operation platform 12 from turning sideways, thereby improving the stability of the operation platform 12.
In this embodiment, the supporting mechanism 230 includes a first supporting member 231 and a second supporting member 232, the first supporting member 231 is hinged to the operating platform 12, the second supporting member 232 is hinged to the traveling device 210, and the hinge axes of the first supporting member 231 and the second supporting member 232, the hinge axis of the first supporting member 231 and the operating platform 12, and the hinge axis of the second supporting member 232 and the traveling device 210 are all parallel to the hinge axis of the first connecting rod 2211 and the second connecting rod 2212.
When the operation platform 12 moves vertically C and longitudinally B simultaneously along with the base 10, the first support 231 and the second support 232 rotate relatively, which does not affect the vertical C movement of the operation platform 12 nor the longitudinal B movement of the operation platform 12, but the support mechanism 230 composed of the first support 231 and the second support 232 can prevent the operation platform 12 from rotating axially around the longitudinal B arrangement, and the support mechanism 230 with such a structure is simple in structure and easy to implement.
Optionally, the first supporting member 231 and the second supporting member 232 are both rod members, one end of the first supporting member 231 is connected to one end of the second supporting member 232, one end of the first supporting member 231, which is far away from the second supporting member 232, is hinged to the operating platform 12, and one end of the second supporting member 232, which is far away from the first supporting member 231, is hinged to the chassis 211 of the walking device 210.
In other embodiments, the supporting mechanism 230 may also be of other structures, for example, as shown in fig. 13, the supporting mechanism 230 is a hydraulic cylinder, one end of the hydraulic cylinder is hinged to the operation platform 12, the other end of the hydraulic cylinder is hinged to the traveling device 210, and the axis of the hydraulic cylinder hinged to the operation platform 12 and the axis of the hydraulic cylinder hinged to the traveling device 210 are both parallel to the hinge axis of the first link 2211 and the second link 2212.
It should be noted that the number of the supporting mechanisms 230 may be one or plural (including two), and the number of the supporting mechanisms 230 may be selected according to the arrangement form of the operation platform 12. The two sides of the base body 10 in the transverse direction a are provided with the operating platforms 12, and then the two support mechanisms 230 can be selected, the two support mechanisms 230 are respectively located on the two sides of the base body 10 in the transverse direction a, one operating platform 12 is connected with the base body 10 through one support mechanism 230, and the other operating platform 12 is connected through the other support mechanism 230.
