Description

Technical Field

[0001] This invention relates to the field of underground gas storage chamber construction technology, and in particular to a construction equipment and process for a curved steel lining sealing layer. Background Technology

[0002] Currently, most compressed air energy storage projects under construction use linear artificial gas storage chambers. However, due to factors such as chamber site selection and excavation techniques, some gas storage chambers require a ring-shaped design, i.e., a continuous, end-to-end structure. For linear gas storage chambers, existing equipment is available for steel lining sealing layer construction. However, for ring-shaped gas storage chambers, the existing equipment cannot be used for the construction of the steel lining sealing layer in the curved sections, resulting in a lack of equipment for curved steel lining sealing layer construction. Because the steel ring cross-section at the bend is irregular, the connection difficulty is greater than in the straight section. Simply using manual assembly methods for connection cannot meet the accuracy requirements and carries significant construction risks, seriously affecting the normal progress of the project. When welding steel tiles at the bend, the connection is difficult and the accuracy is hard to control, directly affecting the construction quality of the steel ring in the bend section, resulting in high overall construction risk. Uncontrollable construction quality and long construction periods are detrimental to the development of ring-shaped gas storage chamber construction methods. Summary of the Invention

One end of the clamping cylinder 3.1.7 is connected to the clamp 3.1.8, and the other end is connected to the gripper connecting beam 3.1.6. The clamp 3.1.8 is hinged to the gripper connecting beam 3.1.6. It should be noted that the gripper connecting beam 3.1.6 is Z-shaped, and the end of the clamping cylinder 3.1.7 furthest from the clamp 3.1.8 is connected to the bottom of the gripper connecting beam 3.1.6.

[0045] It should be noted that the fine-tuning device 3.1 can achieve adjustment in six degrees of freedom, namely translation in three different directions and rotation in three different directions. Among them, the translation adjustment in the three different directions includes: the relative movement of the inner sleeve 3.1.5 and the outer sleeve 3.1.4 of the gripper; the relative movement of the upper translation frame 3.1.12 and the lower translation frame 3.1.13 driven by the longitudinal translation cylinder 3.1.11; and the relative movement of the tilting frame 3.1.15 and the lower translation frame 3.1.13 driven by the transverse translation cylinder 3.1.14. The three rotational adjustments in different directions include: the roller cylinder 3.1.9 driving the second roller 3.1.3 to rotate relative to the upper translation frame 3.1.12; the tilting cylinder 3.1.17 driving the tilting frame 3.1.15 to rotate relative to the tilting base 3.1.18; and the horizontal rotation cylinder 3.1.16 driving the tilting base 3.1.18 to rotate relative to the support 3.1.19. In this way, by adjusting the steel ring in different directions, the docking accuracy requirements of the assembly process are met.

[0046] Please combine Figure 9 Optionally, the construction equipment also includes a work platform 4, which is connected to the end of the assembly module 3 away from the assembly module 2. The work platform 4 is equipped with several jacks 4.1. In this embodiment, multiple jacks 4.1 are arranged along the outer edge of the work platform 4. When assembling the steel rings, if there is a small misalignment, the operator can use the jacks 4.1 to fine-tune the misalignment, ensuring that the final steel ring docking accuracy meets the requirements, thereby improving the steel ring docking accuracy and welding quality.

[0047] Please combine Figure 1 and Figure 10 Optionally, the support legs 1 are provided in three sets, including a front support leg, a middle support leg, and a rear support leg located below the assembly module 2. The rear support leg is closer to the assembly module 3 than the front support leg. Each set of support legs 1 has the same structure, including a first crossbeam 1.1, a leg outer sleeve 1.2, a leg inner sleeve 1.3, a second crossbeam 1.4, a longitudinal movement module 1.5, and a transverse movement module 1.6. The leg outer sleeve 1.2 is connected to the first crossbeam 1.1, and the leg outer sleeve 1.2 and the leg inner sleeve 1.3 are slidably connected. Both ends of the second crossbeam 1.4 are connected to the leg inner sleeve 1.3, and the longitudinal movement module 1.5 and the transverse movement module 1.6 are connected to the leg inner sleeve 1.3.

[0048] In this embodiment, the outer sleeve 1.2 and the inner sleeve 1.3 of the outrigger are connected by hydraulic cylinders to achieve relative sliding. The longitudinal movement module 1.5 and the transverse movement module 1.6 are connected to the inner sleeve 1.3 of the outrigger via hydraulic cylinders, respectively. The outer sleeve 1.2 of the outrigger is connected to the first main beam 2.3. This allows the supporting outrigger 1 to drive the entire circular module 2 to move. The supporting outrigger 1 adopts a step-by-step movement method.

[0049] When turning at the intersection of a straight section and a curve, the principle of movement is as follows: The middle and rear support legs are on the ground, while the front support leg is raised. The lateral movement module 1.6 of the front support leg moves along a fourth direction (e.g., left or right), which corresponds to the turning direction of the curve. If the curve turns left, the lateral movement module 1.6 of the front support leg moves to the left. If the curve turns right, it moves to the right. Then, the front support leg is on the ground, the rear support leg is raised, and the lateral movement module 1.6 of the rear support leg moves along a fifth direction (e.g., right or left), which is opposite to the movement direction of the lateral movement module 1.6 of the front support leg. In other words, the fifth direction is opposite to the fourth direction.

[0050] Afterwards, the rear support leg braces on the ground, and the middle support leg retracts. Then, the longitudinal movement modules 1.5 of the front and rear support legs move forward together. Once the movement reaches its destination, this process is repeated in a loop until the turn is complete, achieving a straight-line turn within the tunnel. It should be noted that when the longitudinal movement modules 1.5 of the front and rear support legs move forward together, both legs are braced on the ground. After the circular module 2 enters the curve section, the hinge angle between the circular module 2 and the main beam of the assembly module 3 is controlled, allowing the assembly module 3 to smoothly pass through the curve.

[0051] When working on a straight section, the middle support leg retracts, and the longitudinal movement module 1.5 of the front support leg and the longitudinal movement module 1.5 of the rear support leg move forward together.

[0052] Please combine Figure 11 and Figure 12 This invention also provides a construction process for a curved steel lining sealing layer, using the aforementioned curved steel lining sealing layer construction equipment, and the process includes: S1. Several steel tiles 5 are sequentially spliced ​​together on the circular module 2 to form a first steel ring 51 and a second steel ring 52; wherein, a reference mark 501 is provided on the steel tile 5 as a positioning point.

[0053] It should be noted that during the processing stage, some steel tiles 5 need to be marked so that the final assembled steel ring has four reference positioning points (upper, lower, left, and right) for alignment during subsequent assembly. The construction equipment is assembled in the tunnel, with the front, middle, and rear support legs in a ground-supporting state.

[0054] During the installation of the straight section of steel tile 5, the assembly module 3 and the circular assembly module 2 are adjusted using the connecting cylinders on both sides to ensure that the second main beam 3.2 of the assembly module 3 and the first main beam 2.3 of the circular assembly module 2 are on the same axis. Then, the crane 2.2 on the first main beam 2.3 is used to place the steel tile 5 from the transfer vehicle onto the first transport trolley. The front support leg is retracted, and the first transport trolley moves between the front and middle support legs. The front support leg is lowered, the middle support leg is retracted, and the first transport trolley moves under the circular assembly device 2.5, and the middle support leg is lowered.

[0055] The steel tile gripper 2.5.1 on the rounding device 2.5 extends, causing the gripping beam 2.5.1.2 to contact the steel tile 5. Power is applied and magnetized, making the gripping beam 2.5.1.2 magnetic, attracting the steel tile 5. The steel tile 5 is then locked in place using bolts and locks 2.5.1.1. The rotary drive 2.4 rotates the rounding device 2.5 by an angle of one steel tile 5. The first transport trolley transports the next steel tile 5 to the rounding device 2.5. The circumferential support rollers on the first transport trolley rotate the steel tile 5, and the rounding device 2.5 rotates synchronously, ultimately connecting the two steel tiles 5. Then, the steel tile gripper 2.5.1 extends at this position, causing the gripping beam 2.5.1.2 to contact the steel tile 5. Power is applied to magnetize the gripping beam 2.5.1.2, attracting the steel tile 5. The steel tile 5 is then locked in place using bolts and locks 2.5.1.1. At this point, the assembly device 2.5 completes the assembly of two steel tiles 5. The gripping and assembly of the entire ring of steel tiles 5 is completed in the same manner. Then, the assembly device 2.5 is rotated so that the joints of adjacent steel tiles 5 are at the lowest point of the ring. The joints are welded, and after each joint is welded, the assembly device 2.5 rotates by the angle of one steel tile 5 until all joints are welded, completing the assembly of multiple steel tiles 5 into a circle, thus forming the first steel ring 51.

[0056] S2. Move the first steel ring 51 onto the assembly module 3. Please refer to... Figure 13 The first steel ring 51 is supported by the support of the second transport trolley; the assembly device 2.5 and the first steel ring 51 are separated; the second transport trolley moves the first steel ring 51 to the fine-tuning device 3.1 of the assembly module 3; the clamp 3.1.8 of the assembly module 3 clamps the first steel ring 51, and the top support device 3.3 of the assembly module 3 supports the first steel ring 51; the position of the first steel ring 51 on the assembly module 3 is adjusted so that the center of the first steel ring 51 coincides with the center of the chamber, the first steel ring 51 is fixed, and the assembly module 3 is separated from the first steel ring 51 and removed; the first steel ring 51 is then cast. Optionally, the specific operation is as follows: Using the second transport trolley, its support rollers rise, supporting the first steel ring 51 on the assembly module 2. The gripping beam 2.5.1.2 of the assembly device 2.5 demagnetizes, the steel tile gripper 2.5.1 retracts, the rear outriggers retract, and the top support device 3.3 of the assembly module 3 retracts. The second transport trolley, carrying the first steel ring 51, moves to the fine-tuning device 3.1 of the assembly module 3. The fine-tuning devices 3.1 at both ends extend outwards, causing the gripper connecting beam 3.1.6 to contact the steel ring. The control clamp cylinder 3.1.7 drives the clamp 3.1.8 to clamp the first steel ring 51. The second transport trolley retracts, preparing to transport the next steel ring (e.g., the second steel ring 52) on the assembly module 2. The top support device 3.3 of the assembly module 3 extends and tightens the first steel ring 51.

[0057] Using a total station and other surveying instruments, along with pre-marked points on the inner wall of the chamber, the position of the first steel ring 51 is adjusted using the fine-tuning device 3.1 on the assembly module 3, so that the center of the first steel ring 51 basically coincides with the center of the chamber. Simultaneously, the points marked on the steel tile 5 are positioned directly above, below, to the left, and to the right of the first steel ring 51. The positioned first steel ring 51 is then fixed using the support frame inside the chamber.

[0058] The top support device 3.3 of assembly module 3 retracts, separating from the first steel ring 51. The support leg 1 moves forward in a stepping manner, driving the assembly device 2.5, assembly module 3, work platform 4, and other construction equipment to move within the chamber. Then, the first steel ring is poured.

[0059] It is understandable that after the first steel ring 51 on the assembly device 2.5 is transferred to the assembly module 3 by the second transport trolley, the assembly device 2.5 can then proceed with the assembly of the next steel ring, and the steps are the same as those for assembling the first steel ring 51.

[0060] Please combine Figure 14 and Figure 15 S3. Move the second steel ring 52 onto the assembly module 3. Optionally, use the second transport trolley to move the second steel ring 52 from the assembly device 2.5 onto the fine-tuning device 3.1 of the assembly module 3, the steps of which are the same as the transfer steps of the first steel ring 51.

[0061] The position of the second steel ring 52 on the assembly module 3 is adjusted using the fine-tuning device 3.1, so that the center of the second steel ring 52 coincides with the center of the first steel ring 51. The four positioning points marked on the second steel ring 52 coincide with the four positioning points on the first steel ring 51. Then, using the jacks 4.1 on the work platform 4, any large misalignments between the first steel ring 51 and the second steel ring 52 are manually fine-tuned. After the misalignment is adjusted to meet the requirements, the circumferential joint between the first steel ring 51 and the second steel ring 52 is welded. The second steel ring 52 is then supported and fixed using the support frame inside the chamber. The support legs 1 move the entire sealing layer construction equipment forward along the chamber to pour the second steel ring 52. The straight section steel lining construction is completed in this manner.

[0062] When the chamber moves from a straight section to a curved section, the principle of movement of the supporting leg 1 is as follows: The middle and rear support legs are on the ground, the front support leg is retracted, and the lateral movement module 1.6 of the front support leg moves along the first direction; after moving, the front support leg is on the ground; the first direction is the turning direction of the curve. For example, if the curve is to the left, it moves to the left. If the curve is to the right, it moves to the right.

[0063] The rear support leg retracts, and the lateral movement module 1.6 of the rear support leg moves along a second direction, which is opposite to the first direction; after the rear support leg moves, it supports the ground. For example, if the road curves to the left, the lateral movement module 1.6 of the rear support leg moves to the right. If the road curves to the right, the lateral movement module 1.6 of the rear support leg moves to the left.

[0064] The middle support leg retracts, and then the longitudinal movement modules 1.5 of the front and rear support legs move forward together; during the movement, both the front and rear support legs are in a ground-supporting state. After the movement reaches the target position, the process is repeated in the same manner until the turn is completed, achieving a straight-line turn within the tunnel. After the circular module 2 enters the curve section, the hinge angle between the circular module 2 and the main beam of the assembly module 3 is controlled, allowing the assembly module 3 to smoothly pass through the curve.

[0065] Optionally, at the transition from the straight section to the curve, the process includes: On the assembly module 2, several steel tiles 5 are sequentially spliced ​​to form a third steel ring 53; reference marks 501 are provided on the steel tiles 5 as subsequent positioning points. Adjust the hinge angle of the first main beam 2.3 and the second main beam 3.2; move the third steel ring 53 onto the assembly module 3; coarsely adjust the position of the third steel ring 53 so that the third steel ring 53 is aligned with the previous steel ring on the assembly module 3; extend the top support on the assembly module 3, and use the fine adjustment device 3.1 to adjust the third steel ring 53 so that the reference mark 501 on the third steel ring 53 is aligned with the reference mark 501 on the previous steel ring on the assembly module 3; weld the third steel ring 53 to the previous steel ring on the assembly module 3; fix the third steel ring 53, and remove the assembly module 3 after it is separated from the third steel ring 53; cast the third steel ring 53.

[0066] The specific steps are roughly as follows: For the transition steel ring between the curved and straight sections, such as the third steel ring 53, one side of its cross-section is regular, while the other side is irregular. The third steel ring 53 is placed on the assembly module 3 in the same manner as the straight section. The entire construction equipment is moved, and the hinge angle between the assembly module 3 and the assembly module 2 is adjusted so that the third steel ring 53 on the assembly module 3 is close to the previous steel ring. Then, the top support device 3.3 on the assembly module 3 is raised, and the fine-tuning device 3.1 is used to perform multi-degree-of-freedom fine-tuning of the third steel ring 53, ensuring that the positioning point on the third steel ring 53 coincides with the positioning point of the previous steel ring. The size of the butt joint of the third steel ring 53 is also adjusted. After the butt joint is completed, the jacks 4.1 on the work platform 4 are used manually to adjust the misalignment between the steel rings. Once the requirements are met, the third steel ring 53 is welded to the previous steel ring. The support frame inside the tunnel is used to fix the third steel ring 53. After the construction equipment is separated from the third steel ring 53 in the aforementioned manner, it moves forward inside the tunnel.

[0067] For the steel rings in the curved sections, the construction process is the same as described above. It is also necessary to ensure that the positioning points on adjacent steel rings coincide, using this as a reference to complete the steel ring assembly. This process is repeated until the entire annular chamber steel lining sealing layer construction is completed.

[0068] Understandably, the entire process, including assembling, pairing, and pouring, can be carried out simultaneously, which greatly improves construction efficiency and shortens the construction cycle.

[0069] In this embodiment, the first steel ring of the straight section is precisely positioned by laser radar, with the marking points made in advance on the inner wall of the tunnel as the positioning reference. In conjunction with the marking positioning points set in advance on the steel ring and the fine adjustment device 3.1 of the assembly module 3, the steel ring is accurately connected in the straight section, transition section and turning section, avoiding the situation where the steel ring in the turning section cannot be connected due to the irregular cross section.

[0070] The curved steel lining sealing layer construction equipment and process provided in this invention can be used to construct the steel lining sealing layer of the annular artificial gas storage chamber in compressed air energy storage projects. The equipment can travel in the curve and complete the steel ring assembly and welding within the curve, with the ability to perform assembly and welding simultaneously. This effectively solves the problem of difficult docking caused by the irregular cross-section of the steel ring in the curved section of the steel lining sealing layer, ensuring docking accuracy while significantly improving construction efficiency, reducing construction risks, and facilitating the rapid advancement of the project.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; any modifications, equivalent substitutions, improvements, etc., should be included within the protection scope of the present invention.
