Description

Technical Field

[0001] This utility model relates to the field of oil drilling and workover rig technology, and in particular to a walking and translating device. Background Technology

[0002] In a well site, there are usually multiple wellheads. When the drilling rig finishes drilling one well and needs to be moved to another well, a translation device is usually used to move the drilling rig to the other well.

[0003] In related technologies, the walking and translation device is usually equipped with two horizontal walking cylinders, one lifting cylinder and rollers. The structure is relatively complex and the size is large, which is not suitable for small drilling rigs. In addition, although the rollers are beneficial for the translation of the drilling rig, the rollers require a lot of installation space, which is not suitable for small drilling rigs with limited installation space. Utility Model Content

[0004] The purpose of this utility model is to provide a walking and translation device that solves the problem that walking and translation devices in related technologies are not suitable for small drilling rigs with limited installation space.

[0005] This utility model is implemented as follows: a walking and translating device includes a sliding seat, a lifting drive device, a single horizontal drive device, and a base. The sliding seat is connected to the device to be transferred through the lifting drive device. The sliding seat and the base are locked vertically and can be relatively movable horizontally. The bottom surface of the sliding seat is in contact with the upper surface of the base. The horizontal drive device is connected to the sliding seat and the base respectively and can drive the sliding seat to slide horizontally back and forth relative to the base.

[0006] The walking and translating device of this utility model is connected to the drilling rig via a lifting drive device. The output end of the lifting drive device extends, causing the walking and translating device to move downwards until the base contacts the ground. Then, the horizontal drive device drives the sliding seat to move horizontally along the base, thereby realizing the translation of the drilling rig. After one translation is completed, the output end of the lifting drive device retracts, the base lifts off the ground, and then the horizontal drive device retracts to drive the base back into position, preparing for the next movement. In this process, considering the limited installation space of small drilling rigs, the sliding seat and the base of this utility model achieve horizontal movement through sliding friction. During this process, the base and the sliding seat are in surface contact, which allows for a smaller size of the sliding seat. At the same time, compared with the prior art, it saves the installation space of the rollers and can also make the overall height of the device smaller. In addition, the horizontal drive device is a single unit, further reducing the space occupied. In summary, the walking and translating device of this utility model eliminates parts and has a more compact structure, meeting the needs of small drilling rigs.

[0007] A further technical solution of this utility model is: a horizontal guide is provided on the base along the sliding direction of the sliding seat, and the horizontal guide is slidably connected to the side of the sliding seat.

[0008] The sliding seat and the base are locked vertically by a horizontal guide. The lifting drive can move the sliding seat and simultaneously lift the base synchronously. In addition, the horizontal guide can ensure that the device is in a straight line during movement, preventing the drilling rig from deviating from the next wellhead during translation.

[0009] A further technical solution of this utility model is: the horizontal guide includes two guide rods, and the sliding seat is located between the two guide rods;

[0010] Each sliding seat has a connecting lug on its side near the guide rod, and each guide rod passes through the corresponding connecting lug and is slidably connected to the connecting lug.

[0011] The sliding seat is located between two guide rods, which makes it more stable during movement. The connecting lug is on the side of the sliding seat, which facilitates assembly with the guide rods and avoids interference with the horizontal drive device.

[0012] A further technical solution of this utility model is: a U-shaped groove with an upward opening is formed on the connecting ear.

[0013] During the process of the lifting drive device raising the sliding seat, the sliding seat rises by connecting the connecting ear and the guide rod. During the downward movement of the sliding seat and base, due to assembly reasons and the connection between the connecting ear and the guide rod, a gap may exist between the sliding seat and the base. To avoid this gap and ensure the horizontal drive device can stably move the sliding seat on the base, once the base contacts the ground, the lifting drive device can continue to lower the sliding seat until it is in contact with the base. During this descent, the connecting ear and the guide rod will move relative to each other. To prevent interference and deformation of the connecting ear and guide rod, an upward-opening U-shaped groove is provided on the connecting ear. In addition, the upward-opening U-shaped groove facilitates the installation of the horizontal guide component.

[0014] A further technical solution of this utility model is: two limiting guide plates are provided on the base along the sliding direction of the sliding seat, and the sliding seat is located inside the two limiting guide plates.

[0015] The sliding seat is placed inside two limiting guide plates to further ensure that the sliding seat does not deviate during the sliding process.

[0016] A further technical solution of this utility model is: a first pin seat is provided on the sliding seat, a second pin seat is provided on the base, and pin holes are respectively provided at both ends of the horizontal drive device;

[0017] The pin hole at one end of the horizontal drive device is aligned with the pin hole of the first pin seat and passes through the first pin to connect with the sliding seat; the pin hole at the other end is aligned with the pin hole of the second pin seat and passes through the second pin to connect with the base.

[0018] The two ends of the horizontal drive device are connected to the base and the sliding seat pin respectively. The two ends of the horizontal drive device can rotate relative to the base and the sliding seat respectively. During the process of the lifting drive device driving the sliding seat to rise and fall, the sliding seat is vertically locked to the base and horizontally movable relative to it, driving the base to rise and fall together, thereby avoiding the horizontal drive device from being directly subjected to force and damaged.

[0019] The two ends of the horizontal drive device are connected to the base and the sliding seat pin respectively. As the lifting drive device drives the sliding seat to move downward, there may be a gap between the sliding seat and the base. Therefore, after the lifting drive device drives the base to contact the ground, the lifting drive device needs to continue to drive the sliding seat downward until the sliding seat and the base are in contact, so as to ensure the stability of the sliding seat in the horizontal relative movement of the base.

[0020] A further technical solution of this utility model is: a cavity is provided through the sliding seat, and the horizontal driving device can be housed in the sliding seat.

[0021] After the drilling rig has moved horizontally, the output end of the horizontal drive mechanism retracts. During this retraction process, the horizontal drive device can be stored in the sliding seat, further reducing the space occupied in the horizontal direction.

[0022] A further technical solution of this utility model is: the lifting drive device is axially locked and circumferentially rotatable to the equipment to be transferred.

[0023] This configuration allows the device to be moved to translate along multiple angles depending on the actual situation.

[0024] A further technical solution of this utility model is: a ring of insertion holes is formed on the upper surface of the sliding seat along the circumference of the lifting drive device, and an insertion rod is movably connected to the device to be transferred, the insertion rod being used to insert into the insertion holes.

[0025] When the traveling and translating device needs to move the equipment to be transferred to the next wellhead, firstly, four traveling and translating devices are installed at the reserved positions at the four corners of the equipment to be transferred. Then, the angle of the traveling and translating devices is adjusted according to the orientation of the next wellhead. Specifically, the angle adjustment is achieved by the lifting drive device rotating circumferentially with the equipment to be transferred. In order to ensure that the angles of the four traveling and translating devices are consistent, this utility model has a ring of insertion holes on the upper surface of the sliding seat. The insertion rod is movably connected to the equipment to be transferred. After all four traveling and translating devices are rotated to the set angle, the equipment to be transferred and the sliding seat are fixed by the insertion rod, thus achieving the consistency of the angles between the four traveling and translating devices and the equipment to be transferred.

[0026] A further technical solution of this utility model is that a handle is provided on the lifting drive device, which facilitates the operation of the lifting drive device.

[0027] The beneficial effects of this utility model are as follows: The walking and translating device of this utility model is connected to the drilling rig through a lifting drive device. The output end of the lifting drive device extends, causing the walking and translating device to move downwards, and the base contacts the ground. Then, the horizontal drive device drives the sliding seat to move horizontally along the base, thereby realizing the translation of the drilling rig. After one translation is completed, the output end of the lifting drive device retracts, the base leaves the ground, and then the horizontal drive device retracts to drive the base back into position, preparing for the next movement. In this process, considering the limited installation space of small drilling rigs, the sliding seat and the base of this utility model achieve horizontal movement through sliding friction. During this process, the base and the sliding seat are in surface contact, which allows for a smaller size of the sliding seat. At the same time, compared with the prior art, the installation space of the rollers is eliminated, and the overall height of the device can be made smaller. In addition, the horizontal drive device is a single unit, further reducing the space occupied. In summary, the walking and translating device of this utility model eliminates parts and has a more compact structure, meeting the needs of small drilling rigs.

[0028] The connecting lug has a U-shaped groove for the horizontal guide to pass through, with the opening of the U-shaped groove facing upwards. During the upward movement of the sliding seat driven by the lifting drive device, the sliding seat rises by engaging with the device's guide rod via the connecting lug. During the downward movement of the sliding seat and base driven by the lifting drive device, gaps may exist between the sliding seat and base due to assembly reasons and the engagement relationship between the connecting lug and the guide rod. To avoid these gaps and ensure the horizontal drive device can stably move the sliding seat across the base, the lifting drive device can continue to lower the sliding seat until it contacts the base. During this descent, the connecting lug will move relative to the guide rod. To prevent interference and deformation of the connecting lug and guide rod, the connecting lug has an upward-facing U-shaped groove. Furthermore, the upward-facing U-shaped groove facilitates the installation of the horizontal guide.

[0029] When the traveling and translating device needs to move the equipment to be transferred to the next wellhead, firstly, four traveling and translating devices are installed at the reserved positions at the four corners of the equipment to be transferred. Then, the angle of the traveling and translating devices is adjusted according to the orientation of the next wellhead. Specifically, the angle adjustment is achieved by the lifting drive device rotating circumferentially with the equipment to be transferred. In order to ensure that the angles of the four traveling and translating devices are consistent, this utility model has a ring of insertion holes on the upper surface of the sliding seat. The insertion rod is movably connected to the equipment to be transferred. After all four traveling and translating devices are rotated to the set angle, the equipment to be transferred and the sliding seat are fixed by the insertion rod, thus achieving the consistency of the angles between the four traveling and translating devices and the equipment to be transferred.

Detailed Implementation

[0038] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0039] Example 1:

[0040] Figure 1-7 A walking and translating device is shown, including a sliding seat 2, a lifting drive device 1, a single horizontal drive device 6, and a base 8. The sliding seat 2 is connected to the device to be transferred through the lifting drive device 1. The sliding seat 2 and the base 8 are locked vertically and can be relatively movable horizontally. The bottom surface of the sliding seat 2 is in contact with the upper surface of the base 8. The horizontal drive device 6 is connected to the sliding seat 2 and the base 8 respectively, and can drive the sliding seat 2 to slide horizontally back and forth relative to the base 8.

[0041] In this embodiment, a horizontal guide 9 is provided on the base 8 along the sliding direction of the sliding seat 2, and the horizontal guide 9 is slidably connected to the side of the sliding seat 2. The sliding seat 2 and the base 8 are locked in the vertical direction by the horizontal guide 9. The lifting drive device 1 can drive the sliding seat 2 to move and simultaneously drive the base 8 to lift and lower synchronously. In addition, the horizontal guide 9 can ensure that the device is in a straight line during the movement, and prevent the drilling rig from deviating from the next wellhead during the translation process.

[0042] In this embodiment, the horizontal guide 9 includes two guide rods, and the sliding seat 2 is located between the two guide rods;

[0043] Each sliding seat 2 has a connecting ear 21 on its side near the guide rod. Each guide rod passes through the corresponding connecting ear 21 and is slidably connected to the connecting ear 21.

[0044] The sliding seat 2 is located between the two guide rods, which makes the sliding seat 2 more stable during movement. Moreover, the connecting ear 21 is on the side of the sliding seat 2, which facilitates the assembly with the guide rods and avoids interference with the horizontal drive device 6.

[0045] In this embodiment, the connecting ear 21 has an upward-facing U-shaped groove. During the process of the lifting drive device 1 driving the sliding seat 2 to rise, the sliding seat 2 drives the base 8 to rise through the connection between the connecting ear 21 and the guide rod. During the process of the lifting drive device 1 driving the sliding seat 2 and the base 8 to move downward, due to assembly reasons and the connection relationship between the connecting ear and the guide rod, there may be a gap between the sliding seat 2 and the base 8. To avoid this gap and ensure that the horizontal drive device 6 can drive the sliding seat 2 to move stably on the base 8, after the base 8 contacts the ground, the lifting drive device 1 can continue to drive the sliding seat 2 to descend until the sliding seat 2 and the base 8 are in contact. During the process of the lifting drive device 1 continuing to drive the sliding seat 2 to descend, the connecting ear 21 will move relative to the guide rod. To avoid interference between the connecting ear 21 and the guide rod, and to prevent deformation of the connecting ear and the guide rod, the connecting ear 21 is provided with an upward-facing U-shaped groove. In addition, the upward-facing U-shaped groove also facilitates the installation of the horizontal guide 9.

[0046] In this embodiment, the lifting drive device 1 is a lifting cylinder.

[0047] In this embodiment, two limiting guide plates 81 are provided on the base 8 along the sliding direction of the sliding seat 2, and the sliding seat 2 is located inside the two limiting guide plates 81.

[0048] The sliding seat 2 is placed inside two limiting guide plates 81 to further ensure that the sliding seat 2 does not deviate during the sliding process.

[0049] In this embodiment, a first pin seat 22 is provided on the sliding seat 2, a second pin seat 82 is provided on the base 8, and pin holes are provided at both ends of the horizontal drive device 6.

[0050] The pin hole at one end of the horizontal drive device 6 is aligned with the pin hole of the first pin seat 22 and passes through the first pin 3 to connect with the sliding seat 2. The pin hole at the other end is aligned with the pin hole of the second pin seat 82 and passes through the second pin 7 to connect with the base 8.

[0051] The two ends of the horizontal drive device 6 are respectively connected to the base 8 and the sliding seat 2 pin. The two ends of the horizontal drive device can rotate relative to the base and the sliding seat respectively. During the process of the lifting drive device 1 driving the sliding seat 2 to rise and fall, the sliding seat 2 can drive the base 8 to rise and fall together through the connection between the connecting ear 21 and the guide rod, thereby avoiding the two ends of the horizontal drive device 6 being directly subjected to force and causing damage to the horizontal drive device 6.

[0052] In this embodiment, a cavity is provided through the sliding seat 2, and the horizontal drive device 6 can be housed inside the sliding seat 2. After the drilling rig has completed its translation, the output end of the horizontal drive device 6 retracts. During this retraction process, the horizontal drive device 6 can be housed inside the sliding seat 2, further reducing the space occupied in the horizontal direction.

[0053] In this embodiment, the horizontal drive device 6 is a horizontal travel cylinder, and the sliding seat 2 includes a housing with an open end. The cylinder end of the horizontal travel cylinder is connected to the second pin seat 82, and the other end passes through the open part of the sliding seat 2 and is connected to the first pin seat 22. When the traveling translation device 11 returns to its original position, the piston rod retracts, which can accommodate the horizontal drive device 6 as much as possible inside the sliding seat 2, reducing space occupation.

[0054] In this embodiment, the lifting drive device 1 is axially locked and circumferentially rotatable to the device to be transferred.

[0055] This configuration allows the device to be moved to translate along multiple angles depending on the actual situation.

[0056] In this embodiment, the lifting drive device 1 is a lifting cylinder, and the equipment to be transferred is a drilling rig. The lifting drive device 1 is axially rotatably connected to the equipment to be transferred. Specifically, the piston rod of the lifting cylinder is rotatable relative to the cylinder body, or the lifting cylinder is connected to the drilling rig through a bearing.

[0057] In this embodiment, a ring of insertion holes 23 is formed on the upper surface of the sliding seat 2 along the circumference of the lifting drive device 1. An insertion rod 12 is movably connected to the device to be transferred, and the insertion rod 12 is used to insert into the insertion holes 23.

[0058] When the traveling translation device 11 needs to move the equipment to be transferred to the next wellhead, four traveling translation devices 11 are first installed at the reserved positions at the four corners of the equipment to be transferred. Then, the angle of the traveling translation device 11 is adjusted according to the orientation of the next wellhead. Specifically, the angle is adjusted by rotating the lifting drive device 1 around the equipment to be transferred. In order to ensure that the angles of the four traveling translation devices 11 are consistent, the present invention provides a ring of insertion holes 23 on the upper surface of the sliding seat 2. The insertion rod 12 is movably connected to the equipment to be transferred. After all four traveling translation devices 11 are rotated to the set angle, the equipment to be transferred and the sliding seat 2 are fixed by the insertion rod 12 to achieve the consistency of the angles between the four traveling translation devices 11 and the equipment to be transferred.

[0059] To facilitate the adjustment of the angle consistency of the four traveling and translating devices, in this embodiment, the upper surface of the sliding seat 2 is provided with a ring of insertion holes 23, and the outer periphery of the insertion holes 23 is provided with angle scale lines, including angles such as 30°, 45°, and 90°. For example, when it is necessary to rotate the drilling rig's translation direction by 90°, the sliding seat 2 is rotated so that the insertion hole 23 corresponding to the 90° angle scale line on the sliding seat 2 is aligned with the position of the insertion rod 12 of the device to be transferred. Then, the insertion rod 12 is passed through the insertion hole 23 to achieve fixation. The angle adjustment of the four traveling and translating devices is completed in sequence to complete the 90° rotation of the drilling rig's translation direction.

[0060] Operation of moving the drilling rig to the next wellhead 10:

[0061] According to Figure 1-2 After installing the drilling rig translation device in the indicated orientation, operate the lifting drive device 1 to lift the drilling rig, and then operate the horizontal drive device 6 to move the drilling rig forward or backward, thus achieving forward and backward translation of the drilling rig. When the drilling rig needs to be translated left or right, the lifting cylinder drives the sliding seat 2 and the base 8 to rotate 90° relative to the drilling rig, and then the insertion rod 12 is inserted into the corresponding insertion hole 23 on the sliding seat 2 to lock the sliding seat and the base 8, thereby achieving a 90° rotation of the translation device 11. Then, the forward and backward translation operation method can be used. Alternatively, the piston rod in the lifting cylinder can rotate 90° relative to the cylinder body, and then the insertion rod 12 is inserted into the corresponding insertion hole on the sliding seat 2, thereby achieving a 90° rotation of the base 8 of the translation device 11. Then, the forward and backward translation operation method can be used.

[0062] The translation device is compact in size, eliminating the rollers used in conventional drilling rigs and converting rolling friction into sliding friction, reducing the number of parts and making the structure more compact. At the same time, the horizontal drive device only includes a horizontal drive device 6 arranged in the middle of the device, further optimizing the overall size. This walking translation device 11 is particularly suitable for drilling and workover rigs, and can be installed in the drilling rig body without taking up extra space, making it very convenient to move the drilling rig to the next wellhead 10.

[0063] In this embodiment, the lifting drive device 1 is provided with a handle for easy operation.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
