Description

Technical Field

[0001] This utility model relates to the field of subway construction technology, specifically a subway construction support device. Background Technology

[0002] A subway is a rapid, high-capacity public transportation system built underground (or partially above ground or elevated) in a city. It mainly transports passengers via dedicated tracks and is an important component of the modern urban transportation network. During subway construction, support devices are required to support and protect the interior of the tunnels.

[0003] A search revealed Chinese authorization announcement number CN222576690U, which discloses a subway construction support device. To address the problems of poor shock absorption leading to easy breakage and limited functionality in existing construction support devices, which fail to meet diverse construction needs, this invention provides a subway construction support device comprising several support rods. A support mechanism is located above each support rod, with a lighting fixture at the bottom. Shock-absorbing devices are installed between each support rod and the support mechanism. Reflective strips are provided on the side walls of the support rods. A reinforcement mechanism for supporting the support mechanism is located at the top of each support rod, and a fixing component is located at the bottom. Anti-vibration pads are placed between the support rods and their corresponding fixing components. This invention offers diverse functions and a unique shock-absorbing device. The lighting fixtures facilitate worker operation, and a switch component controls the lighting. The fixing supports further reinforce the protective mechanism, the reflective strips alert workers to potential collisions, and the anti-vibration pads further dampen the support rods. The shock-absorbing device not only dampens the support mechanism but also helps to clean the lighting fixtures.

[0004] In the existing patent literature, the support rod supports and protects the tunnel interior through the support mechanism. However, since the support plate and the support plate inside the support mechanism have a large area, and the support rod only supports the bottom corner of the support plate, the support plate and the support plate will be dented under stress, affecting the overall stability and safety of the support device. Therefore, it is necessary to propose a support device with auxiliary support to provide auxiliary support for the support plate and the support plate. Summary of the Invention

[0005] The purpose of this utility model is to provide a subway construction support device to solve the problems mentioned in the background section. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a subway construction support device, comprising:

[0007] A support assembly, comprising a base and a support mechanism; the support mechanism is located above the base;

[0008] An auxiliary support assembly includes an upright support rod, a support plate, a connecting ring, a diagonal support rod, and a first spring. The upright support rod is fixed to the top corner of the base. The support plate is slidably connected to the surface of the upright support rod. The connecting ring is slidably connected to the surface of the upright support rod and located below the support plate. The diagonal support rod is fixed between the two sides of the connecting ring and the bottom end of the support plate. The first spring is fixed to the bottom end of the diagonal support rod.

[0009] Furthermore, a fixing ring is fixedly connected to the upper surface of the support rod, and horizontal plates are fixedly connected to both sides of the fixing ring.

[0010] Furthermore, the top end of the horizontal plate is fixedly connected to the bottom end of the first spring, and vertical rods are fixedly connected to both sides of the top end of the anti-support plate.

[0011] Furthermore, the anti-support plate has a circular hole at the connection with the upright support rod, and the anti-support plate moves on the surface of the upright support rod through the circular hole.

[0012] Furthermore, the support assembly also includes a support rod and a vibration damping mechanism; the support rod is fixed at the top corner of the base, and the vibration damping mechanism is fixed between the top of the support rod and the bottom of the support mechanism.

[0013] Furthermore, it also includes limiting components;

[0014] The limiting assembly includes a fixed plate, a second spring, and a telescopic rod; the fixed plate is fixed to both sides above the upright support rod and located below the fixed ring, the second spring and the telescopic rod are both fixed to the center of the bottom inner side of the fixed plate, and the telescopic rod is located inside the second spring.

[0015] Furthermore, the fixed plate and the horizontal plate are placed alternately, the second spring and the top of the telescopic rod are fixedly connected to an auxiliary support plate, and the bottom side of the fixed plate is fixedly connected to the base.

[0016] This utility model has the following beneficial effects:

[0017] This invention, by setting up an auxiliary support component, allows the anti-support plate to be compressed when the support plate and the support plate in the support mechanism are recessed. The force of the recess compresses the anti-support plate, causing it to move downward through the connecting ring. This causes the connecting ring to move downward synchronously with the diagonal brace, which in turn compresses the first spring below the anti-support plate through the diagonal brace. This causes the first spring to contract, and at this time, the connecting ring moves the anti-support plate downward above the fixed ring. The fixed ring then blocks the downward movement of the anti-support plate, and the anti-support plate, through the fixed ring, the diagonal brace, and the first spring, provides auxiliary support to the recessed support plate and the support plate above, preventing them from moving further downward. This allows the support device to continue to be used, thereby protecting the construction personnel inside the tunnel. Attached Figure Description

[0025] 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.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-3 As shown, this utility model is a subway construction support device, comprising:

[0028] The support assembly includes a base 11 and a support mechanism 14; the support mechanism 14 is located above the base 11.

[0029] The support assembly also includes a support rod 12 and a vibration damping mechanism 13; the support rod 12 is fixed at the top corner of the base 11, and the vibration damping mechanism 13 is fixed between the top of the support rod 12 and the bottom of the support mechanism 14.

[0030] The base 11 is used to connect the support rod 12 and the upright support rod 21. The support rod 12 is used to connect the vibration damping mechanism 13 and support the upper support mechanism 14. The vibration damping mechanism 13 is used to dampen the vibration of the support mechanism 14. The support mechanism 14 supports the upper part of the tunnel.

[0031] In this embodiment, the vibration damping mechanism 13 includes an upper connecting plate, a lower connecting plate, and a damper assembly disposed between the two. The lower connecting plate is fixedly connected to the top of the support rod 12, and the upper connecting plate is fixedly connected to the bottom of the support mechanism 14. The damper assembly includes multiple sets of telescopic guide columns evenly distributed along the circumference and buffer springs sleeved around the telescopic guide columns. The two ends of the telescopic guide columns are fixedly connected to the upper connecting plate and the lower connecting plate, respectively. When the support mechanism 14 is subjected to the impact load from the top of the tunnel, the upper connecting plate transmits the pressure to the buffer springs. The buffer springs absorb and dissipate energy through elastic deformation. At the same time, the telescopic guide columns restrict the lateral displacement of the buffer springs, ensuring the stability of vertical vibration damping, effectively reducing the vibration transmitted to the support rod 12 and the base 11, and improving the overall impact resistance and service life of the support device.

[0032] The auxiliary support assembly includes a vertical support rod 21, a support plate 22, a connecting ring 24, a diagonal support rod 25, and a first spring 28. The vertical support rod 21 is fixed at the top corner of the base 11. The support plate 22 is slidably connected to the surface of the vertical support rod 21. The connecting ring 24 is slidably connected to the surface of the vertical support rod 21 and is located below the support plate 22. The diagonal support rod 25 is fixed between the two sides of the connecting ring 24 and the bottom end of the support plate 22. The first spring 28 is fixed to the bottom end of the diagonal support rod 25.

[0033] The upright support rod 21 is used to connect and move the anti-support plate 22. The upright support rod 21 is located on the opposite side of the support rod. The anti-support plate 22 is used to provide auxiliary support for the surface of the support mechanism 14. The connecting ring 24 is used to connect the diagonal support rod 25. The diagonal support rod 25 is used to support the bottom two sides of the anti-support plate 22. The first spring 28 is used to control the range of movement of the diagonal support rod 25 and the connecting ring 24.

[0034] When the support mechanism 14 is subjected to significant pressure, and its internal support plate and support plate begin to dent, the dented portion will first contact the vertical rods 23 on both sides of the top of the anti-bracing plate 22. Since the vertical rods 23 are fixedly connected to the anti-bracing plate 22, the force generated by the dent will be transmitted to the anti-bracing plate 22 through the vertical rods 23.

[0035] The anti-support plate 22 slides downward on the surface of the upright support rod 21 through the circular hole 29, simultaneously causing the connecting ring 24 connected to it to move downward in sync. The downward movement of the connecting ring 24 causes the diagonal support rod 25, which is fixed between its two sides and the bottom end of the anti-support plate 22, to also move, and the first spring 28 at the bottom end of the diagonal support rod 25 is compressed and begins to contract.

[0036] As the support plate 22 continues to move downwards, when it reaches above the fixing ring 26, the fixing ring 26 will prevent the support plate 22 from continuing to move downwards. At this time, the first spring 28 is in a compressed state and has an upward elastic force. This elastic force is transmitted to the support plate 22 through the diagonal brace 25, so that the support plate 22 can provide auxiliary support for the recessed support plate and the guard plate above.

[0037] In this process, the limiting components also play an important role. When the anti-support plate 22 moves downward, causing the horizontal plate 27 to move downward, the horizontal plate 27 will gradually approach the auxiliary support plate 34 inside the fixed plate 31. When the horizontal plate 27 contacts the auxiliary support plate 34, it will compress the second spring 32 and the telescopic rod 33. The second spring 32 is further compressed, providing additional cushioning and support force, while the telescopic rod 33 ensures the stability of the support process and prevents swaying or displacement during the support process.

[0038] The auxiliary support rod 35, which is fixedly connected to the base 11 on one side of the bottom of the fixed plate 31, enhances the stability of the fixed plate 31 and allows the limiting component to function better. Through the coordinated work of the auxiliary support component and the limiting component, the support plate and the support plate are effectively prevented from continuing to move downward, ensuring the stability and safety of the support device and providing reliable protection for construction personnel inside the tunnel.

[0039] Meanwhile, the vibration damping mechanism 13 in the support assembly also plays a continuous role. During construction, various vibrations may occur, such as the operation of excavating equipment and the handling of materials. The vibration damping mechanism 13 can absorb and disperse these vibrations, reducing their impact on the support mechanism 14 and further improving the service life and reliability of the support device.

[0040] Furthermore, the base 11 serves as the foundation of the entire support system, providing stable support for other components. It not only connects the support rod 12 and the upright strut 21, but also bears the weight of the entire support system and the pressure from above the tunnel. Its rational design and robust structure ensure the stability of the support system in complex construction environments.

[0041] In actual construction, this subway construction support device can be flexibly adjusted according to different tunnel conditions. For example, the appropriate length of support rod 12 and upright support rod 21 can be selected according to the width and height of the tunnel; and the first spring 28 and second spring 32 with different elastic coefficients can be selected according to the expected pressure. Through this flexible adjustment, the needs of different subway construction projects can be better met, improving construction efficiency and safety.

[0042] A fixing ring 26 is fixedly connected to the upper surface of the support rod 21, and a horizontal plate 27 is fixedly connected to both sides of the fixing ring 26. The top of the horizontal plate 27 is fixedly connected to the bottom of the first spring 28, and a vertical rod 23 is fixedly connected to both sides of the top of the anti-support plate 22. A circular hole 29 is provided at the connection between the anti-support plate 22 and the support rod 21, and the anti-support plate 22 moves on the surface of the support rod 21 through the circular hole 29. The fixing ring 26 is used for connecting the horizontal plate 27, the horizontal plate 27 is used for connecting the bottom of the first spring 28, the vertical rod 23 is used for supporting the surface of the non-recessed support mechanism 14, and the circular hole 29 is used for the anti-support plate 22 to move on the surface of the support rod 21.

[0043] Furthermore, all components of this support system are made of high-strength, corrosion-resistant materials. The support plates and retaining plates of the support mechanism are made of high-quality steel, possessing excellent compressive and bending resistance, and can withstand significant pressure without easily deforming. The uprights, support rods, and other rod-like components are made of high-strength alloy steel, ensuring the stability and reliability of the structure.

[0044] During installation, first, fix the base in a suitable position at the bottom of the tunnel, ensuring it is stable and secure. Then install the support rods and uprights, ensuring they are perpendicular to the base and tightly connected. Next, install the support mechanism, accurately aligning it with the support rods and uprights. Then, install the auxiliary support components and limiting components in sequence, adjusting the position and clearance of each component to ensure they function properly.

[0045] In daily use, the support system requires regular inspection and maintenance. Inspections include checking for loose connections of all components, proper spring elasticity, and smooth extension and retraction of the telescopic rods. Any problematic components should be replaced or repaired promptly to ensure the support system remains in good working order.

[0046] Furthermore, with the continuous development and advancement of subway construction technology, this support device can be further optimized and upgraded. For example, sensors can be installed on the support structure to monitor the stress on the support plates and retaining plates in real time. When the pressure exceeds the set value, an alarm can be issued in a timely manner to remind construction personnel to take appropriate measures. The support device can also be integrated with an intelligent management system to achieve remote monitoring and management of the support device, improving construction safety and efficiency.

[0047] Working principle: When the component is not in use, the first spring 28 is in the normal extended state, and the top of the vertical rod 23 is in contact with the bottom of the support plate in the support mechanism 14. When the support plate and the support plate in the support mechanism 14 are concave, the force of the concavity squeezes the vertical rod 23 and the anti-support plate 22, causing the anti-support plate 22 to push the connecting ring 24 down, causing the connecting ring 24 to drive the diagonal brace 25 down synchronously. This causes the anti-support plate 22 to squeeze the first spring 28 below through the diagonal brace 25, causing the first spring 28 to contract. This causes the anti-support plate 22 to move down through the connecting ring 24. At this time, the connecting ring 24 moves down to above the fixed ring 26, causing the fixed ring 26 to block the anti-support plate 22 when it moves down. This causes the anti-support plate 22 to provide auxiliary support for the concave support plate and the support plate above through the fixed ring 26, the diagonal brace 25 and the first spring 28, preventing the support plate and the support plate from moving down further, thereby protecting the construction personnel in the tunnel.

[0048] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0049] Limiting assembly; the limiting assembly includes a fixed plate 31, a second spring 32, and a telescopic rod 33; the fixed plate 31 is fixed on both sides above the upright support rod 21 and located below the fixed ring 26, the second spring 32 and the telescopic rod 33 are both fixed to the center of the bottom inner side of the fixed plate 31, and the telescopic rod 33 is located inside the second spring 32; the fixed plate 31 and the horizontal plate 27 are placed alternately, the top of the second spring 32 and the telescopic rod 33 are fixedly connected to an auxiliary support plate 34, and an auxiliary support rod 35 is fixedly connected between the bottom side of the fixed plate 31 and the base 11; the fixed plate 31 is used to connect the second spring 32 and the telescopic rod 33, the second spring 32 and the telescopic rod 33 are used together to connect the auxiliary support plate 34, the auxiliary support plate 34 provides auxiliary support to the other two sides of the bottom of the support plate 22, and the auxiliary support rod 35 provides auxiliary support to the fixed plate 31.

[0050] When the anti-support plate 22 moves downward, its bottom end contacts the auxiliary support plate 34. The auxiliary support plate 34 provides auxiliary support force under the combined action of the second spring 32 and the telescopic rod 33. The second spring 32 generates an upward reaction force after compression, which is transmitted to the anti-support plate 22 through the auxiliary support plate 34, enhancing the support for the upper recessed part; the telescopic rod 33 restricts the lateral displacement of the second spring 32, ensuring stable support without deviation. The auxiliary support rod 35 is fixed at a 45-degree angle between the fixed plate 31 and the base 11, further dispersing the load and preventing the fixed plate 31 from deforming or loosening under pressure. In practical applications, when uneven settlement occurs at the top of the tunnel, the limiting component and the auxiliary support component respond quickly, effectively absorbing impact energy and preventing further deformation of the support mechanism 14, thereby extending the service life of the support device and ensuring construction safety. In addition, the surface of the auxiliary support plate 34 is coated with a wear-resistant coating to reduce frictional loss when in contact with the anti-support plate 22, improving the durability of the component.

[0051] Working principle: When the component is not in use, the anti-support plate 22 does not move down. When the anti-support plate 22 moves down, it moves down along the vertical support rod 21 through the connecting ring 24, causing the bottom sides of the anti-support plate 22 to move down and squeeze the auxiliary support plate 34, causing the second spring 32 and the telescopic rod 33 to move down. When the anti-support plate 22 stops moving down, the second spring 32, the telescopic rod 33, the auxiliary support plate 34 and the auxiliary support rod 35 provide auxiliary support to the other two sides of the bottom of the anti-support plate 22, preventing the anti-support plate 22 from tilting and sinking due to the lack of support components on the other two sides of the bottom.
