Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a rotating structure for bridge construction. Background Technology

[0002] The use of a rotating structure in bridge construction allows the main structure of the bridge to be completed in a non-traffic state, and then rotated as a whole to the designed position. This can avoid the impact of construction on traffic and improve construction safety and efficiency in complex environments.

[0003] However, existing bridge rotation structures have shortcomings. First, the existing bridge rotation structures lack a quick assembly structure between the support legs and the turntable, resulting in low overall construction efficiency. Second, the existing bridge rotation structures lack a self-lubricating structure between the upper and lower ball joints, which reduces the lubricating oil after prolonged use, leading to increased friction and accelerated wear. Therefore, a new bridge rotation structure for bridge construction is proposed to solve these problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a bridge construction rotating structure, which aims to improve the existing bridge rotating structure's lack of a quick assembly structure between the support legs and the turntable, resulting in low overall construction efficiency, and the lack of a self-lubricating structure between the upper and lower ball joints of the existing bridge rotating structure, which leads to a reduction in lubricating oil after long-term use, resulting in increased friction and aggravated wear.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotating structure for bridge construction, comprising a base plate, a platform fixedly connected to the middle of the top of the base plate, a lower ball joint installed at the top of the platform, an upper ball joint installed at the top of the lower ball joint, a turntable installed at the top of the upper ball joint, an annular slide rail fixedly installed on the outer side of the top of the base plate, a plurality of insertion slots being annularly distributed at the bottom of the turntable, a support foot being inserted into the inner wall of each insertion slot, a plurality of locking components being installed at the top of the support foot, a plurality of slots being provided in the inner wall of the insertion slot, a plurality of oil storage chambers being evenly distributed inside the upper ball joint, an oil outlet channel being provided at the bottom of each oil storage chamber, and a self-lubricating component being installed at the top of the oil outlet channel;

[0006] The locking assembly includes a groove, a spring, and a latch. The groove is formed on the top of the support leg, and the spring is fixedly connected to the inner wall of the groove. One end of the spring is fixedly connected to the latch.

[0007] As a further description of the above technical solution:

[0008] The self-lubricating assembly includes an annular seat, a piston, an oil outlet hole, and two springs. The annular seat is fixedly connected to the top of the inner wall of the oil outlet channel. Springs are fixedly connected to both the upper and lower ends of one side of the annular seat. One end of each spring is fixedly connected to a piston. An oil outlet hole is provided inside the piston.

[0009] As a further description of the above technical solution:

[0010] One end of the card engages with the inner wall of the card slot.

[0011] As a further description of the above technical solution:

[0012] The top of one end of the card has a sloping surface.

[0013] As a further description of the above technical solution:

[0014] The oil outlet is T-shaped.

[0015] As a further description of the above technical solution:

[0016] One end of the piston is inserted into the inside of the annular seat.

[0017] As a further description of the above technical solution:

[0018] The outlet of the oil outlet channel is located at the bottom end of the upper ball joint.

[0019] As a further description of the above technical solution:

[0020] The bottom end of the support foot is in contact with the annular slide.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when assembling the turntable and several support legs of the bridge rotation structure, the top of the support legs can be directly aligned and inserted into the insertion groove on the bottom surface of the turntable. Multiple clips are first squeezed back into the groove under the action of the inclined plane, and then popped out under the action of the spring and locked into the slot in the insertion groove to achieve a locking effect, thereby realizing the rapid assembly of the support legs and the turntable and improving the construction and erection efficiency of the bridge rotation structure.

[0023] 2. In this utility model, multiple oil storage chambers are provided in the upper ball joint of the bridge rotation structure. When the upper ball joint rotates, under the action of centrifugal force, the piston in the oil outlet channel will overcome the spring force and move outward, so that the two outlets of the T-shaped oil outlet hole are exposed outside the annular seat. Thus, the lubricating oil in the oil storage chamber can flow out through the oil outlet channel to replenish the lubricating oil between the upper and lower ball joints, thereby reducing friction and avoiding wear.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-6This utility model provides an embodiment of a bridge construction rotating structure, including a base plate 1, which serves as the basic support component of the entire structure and supports the components above it. A platform 2 is fixedly connected to the middle of the top of the base plate 1. A driving structure is provided inside the platform 2 to realize the operation of the rotating structure. A lower ball joint 3 is installed at the top of the platform 2, which is a fixed support component of the rotating structure. An upper ball joint 4 is installed at the top of the lower ball joint 3, and a turntable 5 is installed at the top of the upper ball joint 4. The upper ball joint 4 can rotate relative to the lower ball joint 3, driving the upper turntable 5 and the beam-column structure to rotate. An annular slide 6 is fixedly installed at the top of the base plate 1 on the outside of the platform 2. The annular slide 6 surrounds the platform 2 to provide a stable track. Several insertion slots are distributed in a ring on the bottom of the turntable 5. 12. Insertion slots 12 are used for quick positioning and connection of turntable 5 and the supporting components below. Several inserting slots 12 have support legs 7 inserted into their inner walls. The bottom of the support legs 7 contacts the annular slide 6 and provides support and guidance when the turntable 5 rotates. Several locking components are installed on the top of the support legs 7. Several slots 13 are opened on the inner wall of the insertion slots 12 to cooperate with the locking components on the top of the support legs 7 to achieve fixation. Several oil storage chambers 14 are evenly opened inside the upper ball joint 4. The oil storage chambers 14 are used to store lubricating oil and provide an oil source for lubrication between the upper ball joint 4 and the lower ball joint 3. An oil outlet channel 15 is opened at the bottom of the oil storage chamber 14 so that the lubricating oil can flow out from the oil storage chamber 14. A self-lubricating component is installed on the top of the oil outlet channel 15 to realize the automatic release of lubricating oil and replenish lubrication for the ball joint contact surface.

[0034] Reference Figure 3 The locking assembly includes a groove 8, a spring 9, and a latch 10. The groove 8 is located on the top of the support leg 7. The inner wall of the groove 8 is fixedly connected to the spring 9, and one end of the spring 9 is fixedly connected to the latch 10. The groove 8 provides installation space for the spring 9 and the latch 10. The spring 9 is used to provide elastic force to the latch 10 so that it can automatically pop out after being squeezed and compressed.

[0035] Reference Figure 6 The self-lubricating assembly includes an annular seat 16, a piston 17, an oil outlet 18, and two springs 19. The annular seat 16 is fixedly connected to the top of the inner wall of the oil outlet channel 15. Springs 19 are fixedly connected to both the upper and lower ends of one side of the annular seat 16. One end of each spring 19 is fixedly connected to the piston 17. The springs 19 provide an inward pulling force to the piston 17. An oil outlet 18 is provided inside the piston 17. The piston 17 can slide inside the annular seat 16. The opening and closing of the oil outlet 18 is controlled by the movement to guide the lubricating oil out of the cavity.

[0036] Reference Figure 3 and Figure 4One end of the clip 10 engages with the inner wall of the slot 13, and the engagement action securely locks the support leg 7 into the insertion slot 12 of the turntable 5, ensuring the connection stability during the rotation process.

[0037] Reference Figure 3 The top of one end of the clip 10 is provided with a slope 11. The slope 11 serves as a guide when the support leg 7 is inserted into the insertion slot 12, so that the clip 10 can be smoothly pressed back into the groove 8, which facilitates the quick assembly of the support leg 7.

[0038] Reference Figure 6 The oil outlet 18 is T-shaped, giving it two outlets to enable rapid release of lubricating oil.

[0039] Reference Figure 6 One end of the piston 17 is inserted into the inside of the annular seat 16. When the rotating structure is stationary, the outlet of the oil outlet 18 is located on the inner wall of the annular seat 16 to block the flow of lubricating oil.

[0040] Reference Figure 5 The outlet of the oil outlet channel 15 is located at the bottom end of the upper ball joint 4, ensuring that the lubricating oil can flow directly to the contact surface between the upper ball joint 4 and the lower ball joint 3, effectively reducing the friction between the two.

[0041] Reference Figure 1 The bottom end of the support foot 7 contacts the annular slide 6. By sliding on the annular slide 6, it supports the turntable 5 and guides its rotation, ensuring the stability of the rotation process.

[0042] Working principle: The upper ball joint 4 below the turntable 5 can rotate relative to the lower ball joint 3. A drive structure is set in the base 2 to realize the rotation of the beam column above the turntable 5. Several support legs 7 below the turntable 5 slide on the annular slide rail 6 to provide stable support. When assembling the turntable 5 and several support legs 7 of this bridge rotation structure, the tops of the support legs 7 can be directly aligned and inserted into the insertion slots 12 on the bottom surface of the turntable 5. Multiple clips 10 are first squeezed back into the grooves 8 under the action of the inclined plane 11, and then popped out under the action of the spring 9 and locked into the slots 13 in the insertion slots 12. This serves as a locking mechanism, enabling rapid assembly of the support leg 7 and the turntable 5, thus improving the construction efficiency of the bridge rotation structure. By providing multiple oil storage chambers 14 within the upper ball joint 4 of the bridge rotation structure, when the upper ball joint 4 rotates, under the action of centrifugal force, the piston 17 in the oil outlet channel 15 will overcome the elastic force of the spring 19 and move outward, causing the two outlets of the T-shaped oil outlet hole 18 to protrude outside the annular seat 16. As a result, the lubricating oil in the oil storage chamber 14 can flow out through the oil outlet channel 15, replenishing the lubricating oil between the upper ball joint 4 and the lower ball joint 3, thereby reducing friction and preventing wear.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
