Description
Technical Field
[0001] This utility model belongs to the field of vertical shaft construction technology, and in particular to a vertical shaft annular steel support structure. Background Technology
[0002] In the field of shaft engineering, stable support on the outside of the shaft is a key element in ensuring construction safety and structural stability.
[0003] The existing external support structure for shafts has many limitations:
[0004] Some structural support ranges are fixed, making it impossible to flexibly adjust the support amplitude according to changes in the external dimensions of the shaft, resulting in poor adaptability; some support units operate independently with insufficient synchronization, easily leading to force imbalance on the external side of the shaft, causing structural displacement or damage; the transmission components of the support structure are exposed to the construction environment, making them susceptible to erosion by soil, gravel, and other debris, affecting transmission accuracy and equipment lifespan; some support structures have limited contact area with the external side of the shaft and lack anti-slip design, making slippage easy to occur during support and making it difficult to provide continuous and reliable support force. These problems seriously restrict the safety and efficiency of shaft construction. Summary of the Invention
[0005] To address the aforementioned technical problems, this utility model provides a vertical shaft ring steel support structure, which can solve the shortcomings of poor adaptability, difficulty in flexibly adjusting and replacing scrapers, and inconvenience in construction quality and efficiency. It can be flexibly connected to the main equipment and is height-adjustable; it can adapt to different road widths and corner scenarios, and can quickly replace scrapers of different materials and shapes to meet diverse concrete repair needs.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A vertical shaft annular steel support structure includes a support ring, multiple legs fixedly installed on the outer side of the support ring, a base plate fixedly installed at the bottom end of the legs, a U-shaped seat fixedly installed at the top end of the base plate, a threaded rod rotatably installed between the U-shaped seat and the support ring, a sliding plate threaded onto the threaded rod, a support rod fixedly installed on one side of the sliding plate, one end of the support rod slidingly passing through the support ring and fixedly installed with a support plate, and a drive assembly installed at one end of the threaded rod.
[0008] Preferably, the outriggers are inclined, and multiple outriggers are fixedly installed in a ring at equal intervals on the outside of the support ring, and positioning holes are provided on the base plate.
[0009] Preferably, an arc-shaped groove is provided on one side of the support plate, and the inner wall of the arc-shaped groove is provided with anti-slip texture.
[0010] Preferably, a dustproof plate is fixedly installed between the U-shaped seat and the support ring, and the sliding plate is slidably installed on the dustproof plate.
[0011] Preferably, the drive assembly includes a first rotating shaft, one end of which is fixedly mounted on a threaded rod, and the other end of which passes through one side of a U-shaped seat and is fixedly mounted on a first bevel gear. A second rotating shaft is rotatably mounted between the base plate and the U-shaped seat, and a second bevel gear is fixedly mounted on the second rotating shaft. The first and second bevel gears mesh with each other. A servo motor is fixedly mounted on the top of one of the U-shaped seats, and the output end of the servo motor passes through the U-shaped seat and is fixedly connected to the top of the second rotating shaft.

[0016] The vertical shaft annular steel support structure provided by this utility model has the following beneficial effects:
[0017] Highly adaptable and flexible in adjustment: The drive component drives the threaded rod to rotate, which in turn drives the slide plate, support rod and support plate to move in coordination. The distance between the support plate and the outside of the shaft can be flexibly adjusted to adapt to shafts with different outer diameters and meet diverse support needs.
[0018] Balanced force distribution and stable support: Multiple outriggers are distributed equidistantly in a ring on the outside of the support ring. Combined with a synchronous transmission system consisting of servo motors, bevel gears, and sprockets and chains, this ensures that the force exerted by each support plate on the outside of the shaft is uniform and consistent, effectively preventing structural deformation of the shaft due to uneven force distribution and improving the stability of the support.
[0019] Reliable contact and excellent anti-slip effect: The arc-shaped groove design of the support plate fits tightly with the outer contour of the shaft, and the anti-slip texture on the inner wall increases friction.
[0020] This prevents relative slippage during the support process, ensuring the reliability and continuity of the support.
[0021] Comprehensive protection and extended lifespan: Dust shields protect threaded rods and slide plates, reducing dust intrusion; protective rings prevent chain and other transmission components from entering.
[0022] The moving parts are enclosed inside, and the transmission is guided by guide wheels, which avoids interference and wear of external debris on the transmission system, and significantly improves the operational stability and service life of the equipment.
[0023] Easy installation and efficient operation: The positioning holes on the base plate facilitate quick and easy fixing of the structure to the foundation surface; the overall structural design is compact and efficient in operation.
[0024] The system is easy to operate and can effectively improve the construction efficiency of the external support of the shaft. Attached Figure Description

Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0033] like Figures 1-4As shown, a vertical shaft annular steel support structure includes a support ring 110, multiple legs 120 fixedly installed on the outer side of the support ring 110, a base plate 121 fixedly installed at the bottom end of the legs 120, a U-shaped seat 130 fixedly installed at the top end of the base plate 121, a threaded rod 131 rotatably installed between the U-shaped seat 130 and the support ring 110, a sliding plate 132 threadedly installed on the threaded rod 131, a support rod 133 fixedly installed on one side of the sliding plate 132, one end of the support rod 133 slidingly passing through the support ring 110 and fixedly installed with a support plate 134, and a drive assembly installed at one end of the threaded rod 131.
[0034] In some specific implementation schemes, the outriggers 120 are inclined, and multiple outriggers 120 are fixedly installed in a ring at equal intervals on the outside of the support ring 110. The base plate 121 is provided with positioning holes. This disperses the pressure transmitted from the outside of the shaft and improves the overall load-bearing capacity of the structure. The positioning holes on the base plate 121 facilitate the fixing of the structure to the ground or foundation with bolts or other connectors, avoiding displacement during the support process and enhancing the installation stability of the structure.
[0035] In some specific implementation schemes, an arc-shaped groove is provided on one side of the support plate 134, and the inner wall of the arc-shaped groove is provided with anti-slip texture. The anti-slip texture on the inner wall of the arc-shaped groove can increase the friction between the support plate 134 and the outer side of the shaft, prevent relative sliding between the two, ensure the reliability of the support, and avoid support failure due to slippage.
[0036] In some specific implementations, a dustproof plate 135 is fixedly installed between the U-shaped seat 130 and the support ring 110. The sliding plate 132 is slidably installed on the dustproof plate 135. The dustproof plate 135 is semi-circular and is positioned above the threaded rod 131, with each dustproof plate 135 corresponding to a threaded rod 131. This prevents dust and debris from falling onto the threaded rod 131, avoiding impurities from affecting the thread transmission accuracy between the threaded rod 131 and the sliding plate 132, and reducing component wear. The sliding plate 132 slides on the dustproof plate 135, which provides stable support and guidance for the sliding plate 132, ensuring the smoothness of the sliding plate 132's movement and thus ensuring the movement accuracy of the support plate 134.
[0037] like Figure 2 , Figure 4 and Figure 5As shown, the drive assembly includes a first rotating shaft 140. One end of a threaded rod 131 is fixedly mounted on the first rotating shaft 140. One end of the first rotating shaft 140 passes through one side of a U-shaped seat 130 and is fixedly mounted on a first bevel gear 143. A second rotating shaft 141 is rotatably mounted between the base plate 121 and the U-shaped seat 130. A second bevel gear 144 is fixedly mounted on the second rotating shaft 141. The first bevel gear 143 and the second bevel gear 144 are meshed together. A servo motor 142 is fixedly mounted on the top of one of the U-shaped seats 130. The output end of the servo motor 142 passes through the U-shaped seat 130 and is fixedly connected to the top of the second rotating shaft 141. Multiple second rotating shafts 141 are driven by a gear set. The first bevel gear 143 and the second bevel gear 144 are disposed within the U-shaped seat 130. This ensures that multiple threaded rods 131 are driven synchronously, so that the supporting action of each support plate 134 on the outside of the shaft is consistent, ensuring that the force on the outside of the shaft is uniform.
[0038] The gear set includes sprockets 145 and chains 146. Sprockets 145 are fixedly mounted on the second rotating shaft 141. Multiple sprockets 145 are connected by the chain 146, which runs through the inner wall of the U-shaped seat 130 on both sides. This makes the transmission structure layout more compact, adapts to the space constraints of the support structure, and ensures the continuity and stability of power transmission.
[0039] In some specific implementation schemes, a protective ring 150 is fixedly installed on the top of multiple base plates 121. The protective ring 150 passes through both sides of the inner wall of the U-shaped seat 130. The protective ring 150 is a hollow ring, and the chain 146 is set inside the protective ring 150. The second rotating shaft 141 slides through the protective ring 150. This prevents the chain 146 from being directly exposed to the external environment, prevents dirt, gravel, and other debris from getting entangled or impacting the chain 146, protects the chain 146 and sprocket 145 from damage, and extends the service life of the transmission components. The protective ring 150 passes through both sides of the inner wall of the U-shaped seat 130, which also plays a certain role in connecting and reinforcing the U-shaped seat 130, improving the stability of the overall structure.
[0040] In some specific implementation schemes, multiple guide wheels are rotatably installed between the two sides of the inner wall of the protective ring 150. The chain 146 is slidably connected to the guide wheels, which can guide and limit the transmission direction of the chain 146, prevent the chain 146 from deviating or falling off during transmission, ensure that the chain 146 and the sprocket 145 always maintain a good meshing state, improve the stability and reliability of transmission, and reduce the occurrence of transmission failures.
[0041] The working process of this utility model is as follows:
[0042] Working principle:
[0043] First, the support ring 110 is fitted onto the outside of the shaft and fixed to the ground through the positioning holes on the base plate 121. The support ring 110 serves as the core load-bearing component, and its outer ring of equally spaced inclined support legs 120 further enhances overall stability. When support is needed for the inner wall of the shaft, the servo motor 142 is activated, and its output drives the connected second rotating shaft 141 to rotate. Through a gear set composed of a sprocket 145 and a chain 146 (the chain 146 is guided by a guide wheel within the protective ring 150), multiple second rotating shafts 141 rotate synchronously. The second bevel gear 144 on the second rotating shaft 141 interacts with the first... The first bevel gear 143 on the rotating shaft 140 meshes, causing the threaded rod 131 to rotate between the U-shaped seat 130 and the support ring 110. When the threaded rod 131 rotates, the threaded sliding plate 132 slides along the dustproof plate 135, driving the support rod 133 to pass through the support ring 110 and push the support plate 134 towards the inner wall of the shaft until the arc groove (with anti-slip texture) of the support plate 134 fits tightly with the shaft, thus achieving ring support for the shaft. If the support force needs to be adjusted, the servo motor 142 can be reversed to retract the support plate 134. The entire process achieves precise and synchronous support adjustment through mechanical transmission.
[0044] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
