Description

Technical Field

[0001] This utility model belongs to the field of assembly and relates to an assembly unit suitable for the rotary drilling rig's slewing platform. Background Technology

[0002] Traditional assembly methods for rotary platforms rely on fixed workstations, where multiple processes are carried out in succession. This process is not only complex but also leads to low assembly efficiency. Each process must wait for the previous process to be completed, making it impossible to form a continuous flow operation and thus extending the entire assembly cycle.

[0003] In addition, traditional assembly methods require the rotary platform to be assembled onto the chassis first, and then the upper components are assembled. Due to the high assembly height, operators not only face limited operating space, but also find it difficult to accurately position and adjust the assembled components, which undoubtedly increases the difficulty and inconvenience of the operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an assembly unit suitable for rotary drilling rig slewing platforms. It can meet the requirements of assembly line assembly of slewing platforms and take into account the size differences of different product models. The assembly unit, composed of a slewing platform conveyor line and an assembly line, is used to assemble the slewing platform. The operating height of the components on the slewing platform during assembly is ergonomic.

[0005] The technical solution provided by this utility model is as follows:

[0006] This utility model provides an assembly unit suitable for rotary drilling rig slewing platforms, including a conveyor line and an assembly line. The conveyor line includes a conveyor track and a first RGV trolley running along the conveyor track. The conveyor track is provided with several conveying stations at intervals. The assembly line includes an assembly track and a second RGV trolley running along the assembly track. The assembly track is provided with several assembly stations at intervals. The end of the conveyor track and the beginning of the assembly track intersect perpendicularly, and a transfer station is provided at the perpendicular intersection. The transfer station is provided with a support fixture that allows the first RGV trolley and the second RGV trolley to pass through. Both the first RGV trolley and the second RGV trolley are equipped with a lifting system for raising and transporting the slewing platform to be assembled to the conveyor station, assembly station, or transfer station. The beginning of the conveyor line is provided with an adjustable positioning fixture for adapting to slewing platforms of different sizes.

[0007] Furthermore, the supporting fixtures that allow the first RGV trolley and the second RGV trolley to pass through are portal-shaped supporting fixtures distributed on both sides of the conveyor track. The portal-shaped supporting fixtures include a crossbeam spanning the assembly line track and two columns on each side of the crossbeam. The crossbeam has notches, the distance between the notches is less than the distance between the two sides of the assembly line track, and the bottom height of the crossbeam is greater than the height of the second RGV trolley when its lifting system is retracted. The bottom of the crossbeam and the assembly line track form a passage for the second RGV trolley to pass through. When the first RGV trolley is being transported, the lifting system raises the rotary platform. When it reaches the transfer station at the perpendicular intersection, the lifting system lowers the rotary platform and places it on the portal-shaped supporting fixtures on both sides of the conveyor track to complete the handover with the second RGV trolley.

[0008] Furthermore, the lifting system of the first RGV trolley is provided with two lifting platforms that are symmetrically distributed along the width direction of the first RGV trolley body and parallel to the conveyor rail, and the lifting system of the second RGV trolley is provided with three lifting platforms that are arranged sequentially along the length direction of the second RGV trolley body and perpendicular to the assembly line rail.

[0009] Furthermore, the conveying station includes conveyor support fixtures symmetrically distributed on both sides of the conveyor track. The conveyor support fixtures and the portal-shaped support fixtures are arranged on the same horizontal line. The conveyor support fixtures include a top long crossbeam and two columns located below the long crossbeam.

[0010] Furthermore, the assembly station includes assembly line support fixtures symmetrically distributed on both sides of the assembly line track. Each assembly line support fixture includes a short crossbeam and two uprights located below the short crossbeam. The length between the short crossbeams is equal to the distance between the two uprights below the short crossbeam. The front side of the assembly line support fixture has two portal-shaped support fixtures and the rear side has one portal-shaped support fixture. The distance between the assembly line support fixture and the portal-shaped support fixtures on both sides, as well as the distance between the two portal-shaped support fixtures on the front side, corresponds to the width of the three lifting platforms of the second RGV trolley.

[0011] Furthermore, a gap is provided at the perpendicular intersection of the conveyor track and the assembly line track. The first RGV trolley and the second RGV trolley are each equipped with four sets of independently driven drive wheels. The center distance between two adjacent sets of drive wheels is greater than the width of the gap. When passing through the gap at the perpendicular intersection, one set of drive wheels is suspended in the air while the other three sets of drive wheels remain in contact with the track.

[0012] Furthermore, the positioning fixture includes an axial positioning platform and a radial positioning platform distributed on both sides of the conveyor track. The axial positioning platform is provided with a sliding axial positioning backing, and the radial positioning platform is provided with a sliding radial positioning backing.

[0013] Furthermore, both the first RGV trolley and the second RGV trolley are submersible lifting RGVs, and the load-bearing capacity of the second RGV trolley is greater than that of the first RGV trolley.

The assembly line 2 includes an assembly track 21 and a second RGV trolley running along the assembly track 21. The assembly track 21 is provided with a plurality of assembly stations at intervals. The end of the conveyor track 12 and the beginning of the assembly track 21 intersect perpendicularly, and a transfer station is provided at the perpendicular intersection. The transfer station is provided with a support fixture that allows the first RGV trolley and the second RGV trolley to pass through. Both the first RGV trolley and the second RGV trolley are equipped with a lifting system for lifting and transporting the rotary platform to be assembled to the conveyor station, assembly station, or transfer station. The beginning of the conveyor line 1 is provided with an adjustable positioning fixture 11 for adapting to rotary platforms of different sizes.

[0030] This invention's assembly unit integrates a conveyor line and an assembly line, achieving automated transport and assembly of rotary platforms. The conveyor line transports the rotary platform from its starting position to a transfer station, while the assembly line receives the rotary platform at the transfer station and performs subsequent assembly work. This design improves production efficiency, reduces manual intervention, and lowers production costs. Simultaneously, the assembly unit possesses high flexibility and adaptability; through adjustable positioning fixtures and a lifting system, it can accommodate rotary platforms of different sizes, meeting diverse production needs. Furthermore, the transfer station facilitates smoother connections between the conveyor line and the assembly line, enhancing overall work efficiency.

[0031] Example 2

[0032] like Figures 1 to 3As shown, this utility model embodiment provides an assembly unit suitable for rotary drilling rig slewing platforms, including a conveyor line 1 and an assembly line 2. The conveyor line 1 includes a positioning fixture 11, a conveyor track 12, a conveying station, and a first RGV trolley. The assembly line 2 includes an assembly track 21, an assembly station, and a second RGV trolley. The first RGV trolley and the second RGV trolley run along the conveyor track 12 and the assembly track 21, respectively. The conveyor track 12 and the assembly track 21 are each provided with a number of conveying stations and assembly stations at intervals. The end of the conveyor track 12 and the beginning of the assembly track 21 intersect perpendicularly, and a transfer station is provided at the perpendicular intersection. The transfer station is provided with a support fixture that allows the first RGV trolley and the second RGV trolley to pass through. The first RGV trolley and the second RGV trolley are both equipped with a lifting system for raising and transporting the slewing platform to be assembled to the conveying station, the assembly station, or the transfer station. The beginning of the conveyor line 1 is provided with an adjustable positioning fixture 11 for adapting to slewing platforms of different sizes.

[0033] In this embodiment, the support fixture that allows the first RGV trolley and the second RGV trolley to pass is a portal-shaped support fixture 22 distributed on both sides of the conveyor track 12. The portal-shaped support fixture 22 includes a crossbeam spanning the assembly line track 21 and two columns on each side of the crossbeam. The crossbeam has notches, the distance between the notches is less than the distance between the two sides of the assembly line track 21, and the bottom height of the crossbeam is greater than the height of the second RGV trolley when its lifting system is retracted. The bottom of the crossbeam and the assembly line track 21 form a passage for the second RGV trolley to pass through. When the first RGV trolley is being transported, the lifting system raises the rotary platform. When it reaches the transfer station at the perpendicular intersection, the lifting system lowers and places the rotary platform on the portal-shaped support fixtures on both sides of the conveyor track to complete the handover with the second RGV trolley. The portal-shaped support fixture 22 can meet the support requirements of the rotary platform and ensure that both RGV trolleys traveling in the perpendicular direction can pass through.

[0034] In this embodiment, the lifting system of the first RGV trolley has two lifting platforms symmetrically distributed along the width direction of the first RGV trolley body and parallel to the conveyor rail 12. The lifting system of the second RGV trolley has three lifting platforms arranged sequentially along the length direction of the second RGV trolley body and perpendicular to the assembly line rail 21. The lifting systems of the first RGV trolley and the second RGV trolley adopt two arrangement methods, vertical and parallel rails, respectively, depending on the different placement direction of the rotary platform and the conveying direction.

[0035] In this embodiment, the conveying station includes conveyor support fixtures 13 symmetrically distributed on both sides of the conveyor track 12. The conveyor support fixtures 13 and the portal-shaped support fixtures 22 are arranged on the same horizontal line. The conveyor support fixtures 13 include a top long crossbeam and two columns located below the long crossbeam.

[0036] In this embodiment, the assembly station includes assembly line support fixtures 23 symmetrically distributed on both sides of the assembly line track 21. Each assembly line support fixture 23 includes a short crossbeam and two uprights located below the short crossbeam. The length between the short crossbeams is equal to the distance between the two uprights below the short crossbeam. The front side of the assembly line support fixture 23 is provided with two portal-shaped support fixtures and the rear side is provided with one portal-shaped support fixture. The distance between the assembly line support fixture 23 and the portal-shaped support fixtures 22 on both sides, as well as the distance between the two portal-shaped support fixtures 22 on the front side, corresponds to the width of the three lifting platforms of the second RGV trolley.

[0037] In this embodiment, as Figure 7 As shown, a gap is provided at the perpendicular intersection of the conveyor track 12 and the assembly track 21. The first RGV trolley and the second RGV trolley are each equipped with four sets of independently driven drive wheels. The center distance between two adjacent sets of drive wheels is greater than the width of the gap. When passing through the gap at the perpendicular intersection, one set of drive wheels is suspended in the air while the other three sets of drive wheels remain in contact with the track.

[0038] In this embodiment, as Figure 4 As shown, the positioning fixture 11 includes an axial positioning platform 111 and a radial positioning platform 113 distributed on both sides of the conveyor track 12. The axial positioning platform 111 is provided with a sliding axial positioning backing 112, and the radial positioning platform 113 is provided with a sliding radial positioning backing 114, so as to ensure that the rotary platforms of different models and sizes are correctly aligned.

[0039] In this embodiment, both the first RGV trolley and the second RGV trolley are submersible lifting RGVs, and the load-bearing capacity of the second RGV trolley is greater than that of the first RGV trolley.

[0040] Specifically, such as Figure 5 As shown, the first RGV vehicle is a 15T submersible lifting RGV 14. The 15T submersible lifting RGV 14 includes a vehicle body 141, a drive system 142, control buttons 143, a lidar 144, a touchscreen 145, a portable remote control 146, a battery compartment 147, a hydraulic station 148, a lifting system 149, drive wheels 1410, an emergency stop button 1411, and a safety contact edge 1412. Figure 6As shown, the second RGV is a 30T submersible lifting RGV 24. The 30T submersible lifting RGV 24 includes a vehicle body 241, a drive system 242, control buttons 243, a lidar 244, a touch screen 245, a portable remote control 246, a battery compartment 247, a hydraulic station 248, a lifting system 249, drive wheels 2410, an emergency stop button 2411, and a safety contact edge 2412.

[0041] Specifically, the assembly unit consists of one rotary platform conveyor line and one rotary platform assembly line, arranged perpendicularly. The conveyor line has six conveying stations, with 15t submersible lifting RGVs used for platform transport between stations. The assembly line has nine assembly stations, with 30t submersible lifting RGVs used for platform transport between stations. Each conveyor and assembly station is equipped with support fixtures. Due to the intersection of the lines, to ensure the smooth transfer of the rotary platform from the conveyor line's RGV to the assembly line's RGV, the support fixtures at the transfer stations adopt a "gate" shaped structure. To ensure the RGV trolley can pass through the gap at the intersection of the tracks, the RGV trolley is equipped with four sets of drive wheels. Even when one set of drive wheels is suspended, three sets of drive wheels still support the movement of the trolley, ensuring smooth movement and avoiding risks caused by vehicle vibration. Positioning fixtures are installed at the entrance of the conveyor line to ensure the smooth transport of rotary platforms of different models and sizes and accurate positioning on the support fixtures.

[0042] The 15T and 30T submersible-lift RGVs, during the transport of the rotary platform, elevate the platform using a lifting system to avoid interference from supporting fixtures. After the rotary platform is placed in the designated position, the lifting system retracts, and the RGV moves to the next workstation for the transport task according to instructions. This lifting system allows one or two RGVs to handle the entire transport operation. When there are no tasks, the RGVs automatically travel to a designated charging point to recharge and await further assignments.

[0043] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
