Description

Technical Field

[0001] This application relates to the field of drilling rig technology, and in particular to a rotating support device for a drilling rig cab and a drilling rig. Background Technology

[0002] The drilling rig cab rotation support device mainly consists of a cab, a rotating base, a rotary drive, and a fixed base. The rotary drive is located on the fixed base and has an output end. The rotating base is connected to the output end and can rotate with the output end. The cab is fixed on the rotating base and drives the rotating base to rotate through the rotary drive, thereby driving the cab to rotate. Because there is a limiting mechanism between the cab and the fixed base, the cab can rotate within the range of 0-90°, providing the operator with better visibility and operational comfort.

[0003] However, in practical applications, when drilling rigs are in operation, the cab rotates 90°, providing a wide field of vision. However, the suspended portion of the cab is about 3 / 4 of the overall cab length. When drilling rigs are in relatively uniformly distributed strata, the rig is relatively stable, and the cab is also relatively stable with little shaking. However, when reaming holes in rock strata, due to the uneven hardness of the rock, the reamer drives the drill rod, causing the entire rig to vibrate, which in turn causes the cab to vibrate even more, making it impossible for the operator to work normally.

[0013] A support leg, the upper end of which is rotatably connected to the rotating base; and

[0014] The connector has its upper end rotatably connected to the rotating base and its lower end detachably connected to the support leg.

[0017] The support leg has a second connection hole;

[0018] The drilling rig cab rotary support device also includes:

[0019] A locking element, when the support mechanism is in the folding position, is detachably connected to the first connecting hole and the second connecting hole to restrict the support mechanism within the storage slot.

[0020] In one embodiment, the rotating seat is provided with a connecting seat, a first connecting shaft and a second connecting shaft. The connecting seat is disposed in the storage groove, and the first connecting shaft and the second connecting shaft are both disposed on the connecting seat, and the first connecting shaft and the second connecting shaft are spaced apart along the length direction of the rotating seat.

[0030] The drilling rig cab rotation support device of this utility model has a support mechanism rotatably provided at the bottom of the second end of the rotating seat along its length. When the rotating seat rotates to the point where the second end of the rotating seat is suspended on the fixed seat, the support mechanism can be switched from the folding position to the unfolding position, and the lower end of the support mechanism abuts against the ground or a support on the ground, thereby supporting the second end of the rotating seat to reduce the vibration of the rotating seat, that is, to reduce the vibration of the cab and ensure that the operator can work normally. When the second end of the rotating seat does not need to be supported, the support mechanism can be switched from the unfolding position to the folding position, so that the support mechanism is located on the side close to the bottom of the rotating seat, so as not to affect the rotation of the rotating seat.

[0041] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0042] See Figures 1-6 This invention illustrates a preferred embodiment of a drilling rig cab rotation support device, comprising:

[0043] Fixed base 1;

[0044] Rotary driver 2 is mounted on fixed base 1 and has an output end (not shown in the figure);

[0045] Rotary seat 3 is located above fixed seat 1. The first end of the rotating seat 3 in the length direction is connected to the output end. The rotating seat 3 can rotate with the output end. The rotating seat 3 is used to connect to the cab 4.

[0046] The support mechanism 5 is rotatably disposed at the bottom of the second end of the rotating seat 3 in the length direction. The support mechanism 5 has a folding station close to the bottom of the rotating seat 3 and an unfolding station vertically disposed at the bottom of the second end of the rotating seat 3. The support mechanism 5 rotates to switch between the folding station and the unfolding station.

[0047] The drilling rig cab rotation support device of this utility model has a support mechanism 5 rotatably provided at the bottom of the second end of the rotating seat 3 along its length. When the rotating seat 3 rotates to the point where the second end of the rotating seat 3 is suspended on the fixed seat 1, the support mechanism 5 can be switched from the folding position to the unfolding position, and the lower end of the support mechanism 5 abuts against the ground or a support on the ground, thereby supporting the second end of the rotating seat 3 to reduce the vibration of the rotating seat 3, that is, to reduce the vibration of the cab 4, and to ensure that the operator can work normally. When it is not necessary to support the second end of the rotating seat 3, the support mechanism 5 can be switched from the unfolding position to the folding position, so that the support mechanism 5 is located on the side close to the bottom of the rotating seat 3, so as not to affect the rotation of the rotating seat 3.

[0048] It can be understood that the rotary drive 2 may include a hydraulic motor and a rotary reducer. The hydraulic motor is mounted on the fixed base 1. The inner ring of the rotary reducer is fixed to the fixed base 1. The outer ring of the rotary reducer is the output end. The rotary reducer is connected to the hydraulic motor so that the outer ring of the rotary reducer, i.e. the output end, can rotate under the drive of the hydraulic motor, thereby driving the rotary base 3 to rotate.

[0049] Of course, in other embodiments, the rotary driver 2 may also include a motor and a reducer, with the motor mounted on the fixed base 1, the output shaft of the motor connected to the reducer, and the output shaft of the reducer connected to the rotary base 3.

[0050] See Figure 2 In one embodiment, the center of the support mechanism 5 in the width direction is collinear with the rotation center of the rotating seat 3, so that when the support mechanism 5 is in the unfolded position, the support mechanism 5 can stably support the rotating seat 3, which helps to further reduce the vibration of the rotating seat 3, thereby further reducing the vibration of the cab 4.

[0051] It can be understood that the width direction of the support mechanism 5 refers to... Figure 2 The up and down directions are shown.

[0052] See Figures 4-6 In one embodiment, the bottom of the rotating seat 3 is provided with a storage groove 31. When the support mechanism 5 is in the folding position, the support mechanism 5 is located in the storage groove 31, so that the support mechanism 5 is hidden in the bottom of the rotating seat 3. This can prevent the support mechanism 5 from protruding from the bottom of the rotating seat 3 and hindering the rotation of the rotating seat 3, making the rotation of the rotating seat 3 smoother. At the same time, it can also improve the space utilization of the bottom of the rotating seat 3.

[0053] See Figure 4 In one embodiment, the support mechanism 5 includes:

[0054] Support leg 51, the upper end of support leg 51 is rotatably connected to rotating base 3; and

[0055] Connector 52 has its upper end rotatably connected to the rotating base 3, and its lower end detachably connected to the support leg 51. Thus, when the lower end of connector 52 is connected to the support leg 51, connector 52 restricts the support leg 51 to be vertically supported at the bottom of the second end of the rotating base 3, thereby reliably maintaining the unfolded position of the support mechanism 5. When the lower end of connector 52 is detached from the support leg 51, the support mechanism 5 can be folded up by rotating the upper end of connector 52 relative to the rotating base 3 closer to it, and then rotating the support leg 51 relative to the rotating base 3 closer to it. The support mechanism 5, composed of the support leg 51 and connector 52, is a purely mechanical structure, which not only provides reliable connection and strong stability but also reduces manufacturing costs.

[0056] See Figure 4 In one embodiment, the support leg 51 has a receiving groove 511, and when the support mechanism 5 is in the folded position, the connector 52 is located in the receiving groove 511. Thus, when the support mechanism 5 is in the folded position, the connector 52 can be completely embedded in the receiving groove 511, reducing the overall space occupied and achieving more compact folding and storage, while maintaining a simple and reliable structure.

[0057] See Figures 4-6 In one embodiment, the bottom of the rotating base 3 has a first connecting hole 32;

[0058] The support leg 51 has a second connecting hole 512;

[0059] The drilling rig cab rotary support device also includes:

[0060] When the support mechanism 5 is in the folded position, the locking member 6 can be detachably connected to the first connecting hole 32 and the second connecting hole 512 to lock the support mechanism 5, thereby restricting the support mechanism 5 within the storage slot 31 and preventing the support mechanism 5 from falling out of the storage slot 31. This ensures that the support mechanism 5 is reliably maintained in the folded position. When it is necessary to unfold the support mechanism 5, the locking member 6 can be released to unlock the support mechanism 5. The operation is simple, convenient, and low-cost, which helps to reduce the cost of the rotating support device in the drilling rig cab.

[0061] In one embodiment, the head of the locking member 6 abuts against the support leg 51, and the rod of the locking member 6 passes through the second connecting hole 512 and is screwed to the first connecting hole 32, that is, the locking member 6 is a screw.

[0062] Of course, in other embodiments, the head of the locking member 6 abuts against the support leg 51, the rod of the locking member 6 is sequentially provided with the second connecting hole 512 and the first connecting hole 32, and the rod of the locking member 6 is screwed with a nut, which abuts against the rotating seat 3, that is, the locking member 6 is a bolt.

[0063] Of course, in other embodiments, a telescopic mechanism such as a cylinder or hydraulic cylinder can be used instead of the connector 52. In this way, when the support mechanism 5 switches from the folding position to the unfolding position, the cylinder or hydraulic cylinder extends to support the leg 51. When the support mechanism 5 switches from the unfolding position to the folding position, the cylinder or hydraulic cylinder shortens to allow the leg 51 to fold. At the same time, the cylinder or hydraulic cylinder automatically drives the leg 51 to fold or unfold and keeps the leg 51 in the folding position, without the need for manual operation, making it more convenient to use.

[0064] See Figure 4 In one embodiment, the rotating seat 3 is provided with a connecting seat 33, a first connecting shaft 34 and a second connecting shaft 35. The connecting seat 33 is disposed in the receiving groove 31, and the first connecting shaft 34 and the second connecting shaft 35 are both disposed on the connecting seat 33, and the first connecting shaft 34 and the second connecting shaft 35 are spaced apart along the length direction of the rotating seat 3.

[0065] The upper end of the support leg 51 has a third connecting hole through which the first connecting shaft 34 passes, and the third connecting hole and the first connecting shaft 34 are rotatably engaged.

[0066] The upper end of connector 52 has a fourth connecting hole through which the second connecting shaft 35 passes, and the fourth connecting hole and the second connecting shaft 35 are rotatably engaged, so that the upper end of connector 52 is rotatably connected to the rotating seat 3. In this way, the first connecting shaft 34 and the second connecting shaft 35 are centrally arranged on the connecting seat 33 to achieve a reliable rotatable connection between the support leg 51 and the rotating seat 3, and between connector 52 and the rotating seat 3. The support leg 51 rotates through the third connecting hole engaged with the first connecting shaft 34, and the connector 52 rotates through the fourth connecting hole engaged with the second connecting shaft 35. The dual-axis spacing ensures both structural stability and smooth rotation of each component, resulting in a compact overall structure and coordinated movement.

[0067] See Figure 4 In one embodiment, the support leg 51 has a receiving groove 511. When the support mechanism 5 is in the folded position, the connector 52 and the connecting seat 33 are both located in the receiving groove 511 to improve the space utilization of the support leg 51. At the same time, the height dimension of the receiving groove 31 can be reduced. The smaller height dimension of the receiving groove 31 can avoid reducing the structural strength of the rotating seat 3.

[0068] See Figure 4 In one embodiment, the support leg 51 has a fifth connecting hole;

[0069] The lower end of connector 52 has a sixth connection hole 521;

[0070] Supporting mechanism 5 also includes:

[0071] When the support mechanism 5 is in the unfolded position, the head of the pin 53 abuts against the support leg 51, and the rod of the pin 53 is detachably inserted through the fifth and sixth connecting holes 521 to connect the lower end of the connector 52 to the support leg 51. In this way, the support leg 51 and the connector 52 are detachably connected by the pin 53. The fifth and sixth connecting holes 521 through which the rod of the pin 53 passes provide reliable fixation in the unfolded position. The head of the pin 53 abuts against the support leg 51 to ensure a stable connection. The structure is simple, easy to assemble and disassemble, and securely locked.

[0072] In one embodiment, the rod portion of the pin 53 has a seventh connecting hole, which is perpendicular to the rod portion of the pin 53. When the pin 53 is connected to the fifth connecting hole and the sixth connecting hole 521, the seventh connecting hole is exposed at the end of the support leg 51 away from the head of the pin 53. The seventh connecting hole is used to connect with a limiting component, which restricts the pin 53 from disengaging from the fifth connecting hole and the sixth connecting hole 521, thereby ensuring that the support mechanism 5 reliably maintains the unfolded position.

[0073] See Figures 5-6 In one embodiment, the fixing base 1 is provided with a sleeve 7. When the pin 53 is pulled out, the pin 53 can be inserted into the sleeve 7 to achieve temporary storage of the pin 53, which not only avoids the loss of the pin 53 but also keeps it easy to access.

[0074] A preferred embodiment of this utility model provides a drilling rig, including the aforementioned drilling rig cab rotation support device.

[0075] The drilling rig of this utility model, by adopting the aforementioned rotating support device for the drilling rig cab, can also switch the support mechanism 5 from the folding position to the unfolding position when the rotating seat 3 is rotated to the point where the second end of the rotating seat 3 is suspended on the fixed seat 1. The lower end of the support mechanism 5 is then brought into contact with the ground or a support on the ground, thereby supporting the second end of the rotating seat 3 to reduce the vibration of the rotating seat 3, which in turn reduces the vibration of the cab 4 and ensures that the operator can work normally. When it is not necessary to support the second end of the rotating seat 3, the support mechanism 5 can be switched from the unfolding position to the folding position, so that the support mechanism 5 is located on the side close to the bottom of the rotating seat 3, thus avoiding affecting the rotation of the rotating seat 3.
