Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, and in particular to a drilling rig base lifting mechanism. Background Art

[0002] During the use of drilling rigs, drill pipes often need to be replaced. Since the drill pipes are mostly connected by threads, the process of replacing the drill pipe is basically to use the top drive device to drive the upper drill pipe to rotate to tighten or loosen the two sections of drill pipe.

[0003] Moreover, a derrick is needed to cooperate during the replacement process and the operation of the drilling rig. On the one hand, the derrick is used to bear the weight of the drill pipe downhole, and on the other hand, it has to bear the threat of hurricanes during the drilling process. The derrick requires a base of a certain height to cooperate with the support. The existing base is usually designed directly according to the required height, which may easily lead to the following situation: the base is relatively high as a whole. In the early stage of transporting the base by truck, it is easy to face road height restrictions, resulting in the inability to transport the base smoothly. Utility Model Content

[0004] The utility model proposes a drilling rig base lifting mechanism, which solves the problem in the related art that the base is usually directly designed according to the required height, which leads to the problem that the base is easily restricted by roads during transportation, resulting in failure to transport the base smoothly.

[0009] A lifting telescopic member is arranged statically relative to the frame, and has a top end, which is used for lifting after being retracted, and drives the base to move away from the frame.

[0010] As a further technical solution, the lifting slot is arranged in the vertical direction, and further comprises:

[0011] A lifting rail is arranged on the bottom of the base and is located in the lifting slot, and the lifting rail follows the base to rise and fall in the lifting slot.

[0012] As a further technical solution, the lifting rail is in an I-shape.

[0013] As a further technical solution, there are four of each of the rack and the lifting rails, one lifting rail is located in one lifting slot, and the four lifting rails are arranged in a matrix.

[0015] The base, the four frames and the lifting and telescopic member are all vertically arranged on the top of the base, the frame also has a limiting hole, and the lifting and telescopic member passes through the limiting hole.

[0016] As a further technical solution, the top is spherical, and the bottom of the base has an arc-shaped top groove, the top extends into or out of the arc-shaped top groove after telescoping, the lifting groove has a first limiting hole, the lifting rail has a second limiting hole, and after the base is lifted, the first limiting hole is connected to or cancels the connection with the second limiting hole, and further includes:

[0023] As a further technical solution, the frame further has a storage hole, and the storage hole is used to store the limiting member.

[0024] The working principle and beneficial effects of the utility model are:

[0025] In the present invention, the drilling rig working process and the drill rod replacement process both require the cooperation of the derrick. On the one hand, the derrick is used to bear the weight of the drill rod in the well, and on the other hand, it also bears the threat of hurricanes during the drilling process. Since the derrick is a large steel structure, its early configuration and installation steps are relatively cumbersome. Specifically, it is necessary to use a large truck to transport the base to the designated location, and then arrange the base, and fix the base and the truck's vehicle chassis, and then use the jacking device to erect the derrick and connect it to the base. Since the subsequent installation of drill rods and drill rod work require working and installation space, there are height requirements for the base that supports the derrick, and the existing base is usually designed directly according to the required height, but the following situation is prone to occur: the base is overall high, and in the early stage of using a truck to transport the base, it is easy to face road height restrictions, resulting in the inability to smoothly transport the base.

[0026] In view of the transportation difficulties caused by the fixed height of the existing base, the mechanism adopts an adjustable design so that the base can be adjusted to a lower position before transportation, easily avoiding the height limit obstacles on the road, greatly facilitating the long-distance transportation of the base. After arriving at the work site, the base is adjusted to the required height through the lifting mechanism, which not only solves the transportation problem, but also ensures the rapid installation and deployment on site, reducing the cost and time consumption of the initial installation and configuration. When used specifically: during truck transportation, the base descends in the lifting slot until the top of the retracted lifting telescopic part abuts, which is the lowest height state, which can meet the height limit requirements of the truck on various roads; after the truck transports it to the designated location, the top end extends out to lift the base, so that the base is away from the frame until the required base height is reached, meeting the conditions for subsequent drilling rig work and drill rod replacement.

[0027] The use of the lifting groove is mainly to ensure the stability of the base during the lifting process. The specific lifting groove can be a deeper rectangular rigid structure groove to enhance the limiting and guiding function during the sliding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes a drilling rig base lifting mechanism, including: a frame 1, the frame 1 has a lifting slot 101; a base 2, the base 2 is lifted and arranged in the lifting slot 101, located above the frame 1, and the base 2 is close to or away from the frame 1 after being lifted; a lifting telescopic member 3, the lifting telescopic member 3 is stationary relative to the frame 1, the lifting telescopic member 3 has a top end 301, and the top end 301 is used for lifting after being retracted, and drives the base 2 away from the frame 1.

[0038] In this embodiment, Figures 1 to 3As shown, both the drilling rig working process and the drill rod replacement process require the cooperation of the derrick. On the one hand, the derrick is used to bear the weight of the drill rod underground, and on the other hand, it also has to bear the threat of hurricanes during the drilling process. Since the derrick is a large steel structure, its early configuration and installation steps are relatively cumbersome. Specifically, it is necessary to use a large truck to transport the base 2 to the designated location, and then arrange the base 2, and fix the base 2 and the truck's chassis. Then, the derrick is erected using a jacking device and connected to the base 2. Since the subsequent installation of drill rods and drill rod work require working and installation space, there are height requirements for the base 2 for installing and supporting the derrick, and then the existing base 2 is usually designed directly according to the required height, but the following situation is prone to occur: the base 2 is relatively high as a whole. In the early stage of transporting the base 2 by truck, it is easy to face road height restrictions, resulting in the inability to smoothly transport the base 2.

[0039] In view of the transportation difficulties caused by the fixed height of the existing base 2, the mechanism adopts an adjustable design, so that the base 2 can be adjusted to a lower position before transportation, easily avoiding the height limit obstacles on the road, greatly facilitating the long-distance transportation of the base 2. After arriving at the work site, the base 2 is adjusted to the required height through the lifting mechanism, which not only solves the transportation problem, but also ensures the rapid installation and deployment on site, reducing the cost and time consumption of the initial installation and configuration. In specific use: during the transportation by truck, the base 2 descends in the lifting groove 101 until the top 301 of the retracted lifting telescopic member 3 abuts, which is the lowest height state, which can meet the height limit requirements of the truck on various roads; after the truck transports it to the designated position, the top 301 extends out to lift the base 2, so that the base 2 is away from the frame 1 until the required base 2 height is reached, meeting the conditions for subsequent drilling rig operation and drill rod replacement.

[0040] The lifting groove 101 is mainly used to ensure the stability of the base 2 during the lifting process. Specifically, the lifting groove 101 can be a deeper rectangular rigid structure groove to enhance the limiting and guiding function during the sliding process.

[0041] Furthermore, the lifting slot 101 is arranged along the vertical direction, and further comprises: a lifting rail 4 , which is arranged on the bottom of the base 2 and is located in the lifting slot 101 , and the lifting rail 4 follows the base 2 to be lifted and lowered in the lifting slot 101 .

[0042] Furthermore, the lifting rail 4 is in an I-shape.

[0043] In this embodiment, Figures 1 to 3As shown, more specifically, the lifting groove 101 is arranged in the vertical direction, and the lifting rail 4 welded to the bottom of the base 2 provides the function of a slide rail, so that it is located in the lifting groove 101, replacing the base 2, to ensure that the base 2 functions normally. At the same time, the lifting rail 4 follows the base 2 to rise and fall in the lifting groove 101, so that the rectangular lifting groove 101 and the I-shaped rigid lifting rail 4 can jointly play a stable limiting guiding role.

[0044] Furthermore, there are four racks 1 and four lifting rails 4 , one lifting rail 4 is located in one lifting slot 101 , and the four lifting rails 4 are arranged in a matrix.

[0045] In this embodiment, Figure 2~3 As shown, four sets of matrix-arranged frames 1 and lifting rails 4 are used, and one lifting rail 4 is located in a lifting slot 101, so that the lifting mechanism ensures that during the operation of the drilling rig and the replacement of the drill rod, the derrick can stably bear the weight of the drill rod, effectively resist the impact of extreme weather such as hurricanes, and improve the stability and safety of the operation. At the same time, the load-bearing capacity and anti-overturning ability of the base 2 are further improved, so that the derrick can work stably under various complex working conditions.

[0046] Furthermore, it also includes: a base 5, four frames 1 and a lifting and telescopic member 3 are vertically arranged on the top of the base 5, the frame 1 also has a limiting hole 102, and the lifting and telescopic member 3 passes through the limiting hole 102.

[0047] In this embodiment, Figure 2~3 As shown, a base 5 is vertically welded at the bottom of the four sets of frames 1 and the lifting rails 4 to form a complete drilling rig base 2. The base 5 is arranged along the horizontal plane to provide stable support for the whole.

[0048] Furthermore, limiting holes 102 are provided on the four groups of matrix-arranged racks 1, in order to provide a stable installation position for the lifting telescopic parts 3 so that they pass through the limiting holes 102. At the same time, like the rack 1, the four groups of lifting telescopic parts 3 are also arranged in a matrix, and work together in the vertical direction to lift the base 2, which can be achieved by using devices such as lifting hydraulic cylinders. The lifting telescopic parts 3 are installed on one side adjacent to the rectangular rack 1 through the limiting holes 102 and fasteners.

[0049] Furthermore, the top 301 is spherical, and the bottom of the base 2 has an arc-shaped top groove. After the top 301 is telescoped, it extends into or out of the arc-shaped top groove. The lifting groove 101 has a first limiting hole 103, and the lifting rail 4 has a second limiting hole. After the base 2 is lifted, the first limiting hole 103 is connected to or cancels the connection with the second limiting hole. It also includes: a limiting member 6, which is slidably set in the first limiting hole 103, and the limiting member 6 is used to pass through the first limiting hole 103 and the second limiting hole.

[0050] Furthermore, it also includes: a supporting telescopic member 7, which is hingedly arranged on the top of the base 5, and the supporting telescopic member 7 has a telescopic end 701, and the telescopic end 701 is hingedly arranged on the bottom of the base 2, and the supporting telescopic member 7 is inclined.

[0051] In this embodiment, Figure 2~3 As shown, in order to minimize the damage to the base 2 caused by the top 301 reciprocatingly lifting the base 2, the top 301 is designed to be spherical, and an arc-shaped top groove is correspondingly opened at the bottom of the base 2. The top 301 can abut against the arc-shaped top groove after expansion and contraction.

[0052] Since the base 2 is heavier as a whole, even if the four groups of lifting telescopic parts 3 arranged in a matrix and acting in the vertical direction can lift the base 2, the base 2 and the derrick thereon need to be kept in a state of long-term use. The lifting telescopic parts 3 in the form of hydraulic cylinders cannot meet the requirements of the above state, which may damage the lifting telescopic parts 3 and cause safety accidents. In order to avoid the above situation, additional safety limit measures are provided. The lifting rail 4 sliding in the lifting groove 101 is used to open a first limit hole 103 in the lifting groove 101, and the lifting rail 4 is provided with a second limit hole. When the base 2 is lifted up to connect the two limit holes 102, the columnar limit part 6 is allowed to pass through the two, and the lifting rail 4 is clamped in a fixed position in the lifting groove 101. At the same time, in order to ensure different height requirements of the base 2, a plurality of second limit holes can be provided on the lifting rail 4 along vertical intervals. When the limit part 6 is clamped, the top 301 can be retracted, and the entire base 2 is supported by the connection between the lifting rail 4 and the frame 1.

[0053] Furthermore, in order to improve the effect of supporting the base 2 and avoid relying solely on the lifting rail 4 and the frame 1, a supporting telescopic member 7 in the form of a cylinder or the like is hingedly provided on the base 5, and its telescopic end 701 is also hinged to the bottom of the base 2. After the limit member 6 is assembled and the top end 301 is retracted, the telescopic end 701 of the supporting telescopic member 7 also plays a certain supporting role. At the same time, the four groups of supporting telescopic members 7 arranged in a matrix are all tilted to ensure a more stable supporting structure.

[0054] Furthermore, it also includes: a support 8, the support 8 is arranged on the frame 1, and the bottom of the support 8 has a lifting foot 801, after the lifting foot 801 is raised and lowered, the height of the lifting foot 801 is higher or lower than the height of the base 5.

[0055] In this embodiment, Figure 2~3As shown, in order to facilitate the unloading of the base 5, the frame 1 and other components from the truck after they are transported to the designated location, a support 8 is installed on the frame 1 using the working structure and similar principles of many loading trucks. The lifting legs 801 at the bottom of the support 8 can be extended and retracted to support the entire base 5, the frame 1 and other components. In other words, after the truck is transported to the designated location, the lifting legs 801 are extended to contact the ground to support the entirety. The truck can then be stably detached and the entirety can be unloaded. After that, the lifting legs 801 are retracted to stably place the entirety and continue with subsequent work.

[0056] Furthermore, the support 8 is hingedly arranged on the frame 1 , and the hinge axis of the support 8 is parallel to the length direction of the lifting slot 101 .

[0057] In this embodiment, Figure 2~3 As shown, in order to ensure that the unloading is more stable as a whole and to ensure that the position of the lifting leg 801 supports various ground conditions, it is necessary that the supporting position can be adjusted when the truck is fixed. This is because if it is adjusted by the truck, it may not meet the requirements for the specified position of the base 2. Therefore, the support 8 is hingedly set on the frame 1, and the hinge axis is parallel to the length direction of the lifting slot 101, that is, the vertical direction.

[0058] Furthermore, the frame 1 also has a storage hole 104 , and the storage hole 104 is used to store the limiting member 6 .

[0059] In this embodiment, Figure 2~3 As shown, a storage hole 104 is also provided on the frame 1, in which the limiting member 6 can be stored when it is not in use.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
