Description

Technical Field

[0001] This utility model relates to the field of bridge erecting machine support technology, and in particular to an auxiliary support structure for the outriggers of a bridge erecting machine. Background Technology

[0002] In the field of modern bridge construction, the performance of the outrigger auxiliary support structure of the bridge erecting machine, as a key construction equipment, directly affects construction safety and efficiency. The outrigger auxiliary support structure of the bridge erecting machine refers to the additional support device added to the outrigger system of the bridge erecting machine (a large piece of equipment used for bridge construction) to enhance its stability, load-bearing capacity and adaptability to complex working conditions.

[0003] The auxiliary support structure of the bridge erecting machine's outriggers mainly consists of a support base plate, cylinders, and a support top plate. First, the support base plate is fixedly installed at the bottom of the bridge erecting machine's outriggers, serving as a basic support and connection. When the bridge erecting machine needs to operate or adjust its support status, the cylinders start working, pushing the support top plate upward and downward through telescopic movements. The support top plate contacts the main structure of the bridge erecting machine and the parts to be supported, ensuring the safe operation of the equipment under complex working conditions.

[0004] In the prior art, some auxiliary support structures for the outriggers of bridge erecting machines typically use fixed and simple auxiliary support methods to support the outriggers. However, when faced with large loads and complex working environments, these auxiliary support structures often fail to effectively alleviate the pressure on the outriggers. When the outriggers are under pressure, the lack of sufficient pressure relief measures leads to the concentration of pressure on the outriggers, which cannot be evenly distributed, reducing the pressure relief stability, reducing safety and reliability, and posing certain safety hazards. In order to address the above problems, an auxiliary support structure for the outriggers of bridge erecting machines is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an auxiliary support structure for the outriggers of a bridge erecting machine, which aims to improve the problem that some devices in the prior art cannot reduce pressure, resulting in poor stability in pressure reduction and resistance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bridge erecting machine outrigger auxiliary support structure includes a support base plate. Multiple cylinders are fixedly connected to the top of the support base plate. A support top plate is fixedly connected to the drive end of each cylinder. A limit fixing mechanism is fixedly connected to the top of the support top plate. A deceleration mechanism is fixedly connected to the bottom of the support base plate. The deceleration mechanism includes multiple transmission columns. The top of each transmission column is fixedly connected to the bottom of the support base plate. A connecting support block is fixedly connected to the bottom of each transmission column. A sliding column is fixedly connected to the bottom of each connecting support block. A telescopic spring is sleeved on the outside of each sliding column. A fixed base plate is fixedly connected to the bottom of each telescopic spring. A telescopic rubber block is fixedly connected to the bottom of each telescopic rubber block. A telescopic silicone pad is fixedly connected to the bottom of each fixed base plate. A support base plate is fixedly connected to the outside of each fixed base plate. An anti-compression component is fixedly connected to the inner bottom of the support base plate.

[0008] As a further description of the above technical solution:

Each supporting base column has multiple reinforcing columns fixedly connected inside, and the bottom of the multiple reinforcing columns is fixedly connected to a reinforcing steel plate. The bottom of the reinforcing steel plate is fixedly connected to a reinforcing steel mesh. Each supporting base column has multiple supporting rods fixedly connected to the outside.

[0010] As a further description of the above technical solution:

[0011] The limiting and fixing mechanism includes a connecting support frame, the bottom of which is fixedly connected to the top of the supporting top plate, a frame reinforcement plate fixedly connected to the top of the connecting support frame, two connecting limiting plates slidably connected to the outside of the connecting support frame, and a sliding component fixedly connected to the top of the supporting top plate.

[0012] As a further description of the above technical solution:

[0013] The sliding assembly includes two drive slide rails, and a follower connecting column is fixedly connected to the top of the two drive slide rails. The follower connecting column is externally fixedly connected to the inside of the bottom side of the connecting limiting plate.

[0014] As a further description of the above technical solution:

[0015] A connecting reinforcing rod is fixedly connected to the outside of every two cylinders, and a supporting telescopic column is fixedly connected to the top of the supporting base plate. The top of the supporting telescopic column is fixedly connected to the bottom of the supporting top plate.

[0018] As a further description of the above technical solution:

[0019] The outer bottom side of the sliding column is slidably connected to the inside of the fixed chassis, and the bottom of the sliding column is slidably connected to the inner top of the supporting base plate.

[0020] As a further description of the above technical solution:

[0021] The support rod is externally fixedly connected to the inside of the support base column, and the reinforcing steel mesh is externally fixedly connected to the inside of the support base column.

[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 Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of an auxiliary support structure for a bridge erecting machine leg, including a support base plate 1. The support base plate 1 is the basic component of the entire auxiliary support structure for the leg, serving as a connection. The support base plate 1 has sufficient strength and rigidity to withstand the huge load transmitted from the bridge erecting machine leg and evenly distribute it to the damping mechanism and other components below, ensuring the stability and reliability of the entire support structure. It ensures that when the cylinder 2 is working, the power can be accurately transmitted to the support top plate 4, and the cylinder 2 can smoothly perform lifting and lowering actions to adapt to the height requirements of the bridge erecting machine leg under different working conditions. Multiple cylinders 2 are fixedly connected to the top of the support base plate 1. The cylinder 2 is the key component for driving the lifting and lowering of the support top plate 4. Through the piston movement inside, hydraulic energy is converted into mechanical energy, thereby realizing the up and down movement of the support top plate 4. The drive ends of the multiple cylinders 2 are fixedly connected to the support top plate 4. The support top plate 4 is located above the support base plate 1 and realizes up and down movement through the fixed connection with the drive ends of the cylinders 2. The top of the support top plate 4 is fixedly connected to a limit fixing mechanism, and the bottom of the support base plate 1 is fixedly connected to a damping mechanism.

[0034] The load reduction mechanism includes multiple transfer columns 6, which transfer the load from the support base plate 1 downwards. The top of the transfer column 6 is fixedly connected to the bottom of the support base plate 1, and the bottom of the transfer column 6 is fixedly connected to a connecting support block 7, which serves as a transition and support. The bottom of the connecting support block 7 is fixedly connected to a sliding column 8, and a telescopic spring 9 is sleeved on the outside of the sliding column 8. The bottom of the telescopic spring 9 is fixedly connected to a fixed base plate 10. The telescopic spring 9 is elastic and can undergo elastic deformation when subjected to load, thereby playing a role in buffering and shock absorption. When the bridge erecting machine's outriggers generate impact loads... When loaded, the telescopic spring 9 can absorb some energy and reduce the impact of the load on the support structure. The bottom of the support base plate 1 is fixedly connected to a telescopic rubber block 23, and the bottom of the telescopic rubber block 23 is fixedly connected to a telescopic silicone pad 24. Both rubber and silicone have good elastic properties. The telescopic rubber block 23 and the telescopic silicone pad 24 can undergo elastic deformation when subjected to load, which plays a further role in buffering and shock absorption. The external of multiple fixed base plates 10 is fixedly connected to a support base plate 5. The support base plate 5 is the connecting part between the load reduction mechanism and the anti-pressure component, and plays a role in transmitting load and providing support.

[0035] The anti-compression component is tightly connected to the supporting base plate 5 to jointly bear the load. The supporting base plate 5 is designed with sufficient strength and rigidity to ensure that it will not deform or be damaged when subjected to large loads, thereby ensuring the stability of the entire support structure. The fixed base plate 10 provides a stable support point for the telescopic spring 9, ensuring that the telescopic spring 9 can work normally. The anti-compression component is fixedly connected to the bottom inner side of the supporting base plate 5. The anti-compression component includes a supporting base column 15. The top of the supporting base column 15 is fixedly connected to the bottom inner side of the supporting base plate 5. Each supporting base column 15 has multiple reinforcing columns 11 fixedly connected inside, including support columns. The base column 15, reinforcing column 11, reinforcing steel plate 12, reinforcing steel mesh 13, and support rod 14 are provided. The base column 15 supports and transmits loads. The reinforcing column 11 enhances the strength and rigidity of the base column 15, enabling it to withstand greater loads. The bottom of multiple reinforcing columns 11 is fixedly connected to the reinforcing steel plate 12, which further enhances the load-bearing capacity of the base column 15 and prevents deformation and damage to the base column 15 during stress. The bottom of the reinforcing steel plate 12 is fixedly connected to the reinforcing steel mesh 13, which can distribute the load and improve the compressive strength and stability of the base column 15.

[0036] Each supporting column 15 is externally fixedly connected to multiple supporting rods 14. The supporting rods 14 enhance the stability of the supporting column 15, preventing lateral deformation and tilting during stress. The bottom of the multiple supporting rods 14 is fixedly connected to the top of the supporting anti-slip block 16, increasing the friction between the supporting structure and the ground and preventing the supporting structure from sliding during operation. The supporting anti-slip block 16 can increase the friction between the supporting structure and the ground, preventing the supporting structure from sliding during operation, thereby improving the stability of the entire supporting structure. The bottom of the multiple reinforcing columns 11 is fixedly connected to reinforcing steel plates 12, and the bottom of the reinforcing steel plates 12 is fixedly connected to reinforcing steel mesh 13. Each supporting column 15 is externally fixedly connected to multiple supporting rods 14.

[0037] Reference Figure 2 and Figure 4 The limiting and fixing mechanism includes a connecting support frame 18, which provides a stable support foundation for the entire limiting and fixing mechanism. The bottom of the connecting support frame 18 is fixedly connected to the top of the supporting top plate 4, and the top of the connecting support frame 18 is fixedly connected to a frame reinforcement plate 19, which strengthens the connecting support frame 18 and enables it to withstand the load transmitted from the outriggers of the bridge erecting machine, preventing the connecting support frame 18 from deforming or being damaged during the stress process. Two connecting limiting plates 17 are slidably connected to the outside of the connecting support frame 18, and the top of the supporting top plate 4 is fixedly connected to... The sliding assembly includes two drive slide rails 20 for sliding on the connecting support frame 18, thereby clamping and fixing the bridge erecting machine. The top of the two drive slide rails 20 is fixedly connected to a follower connecting column 21. The drive slide rails 20 guide and limit the connecting limiting plate 17 of the limiting and fixing mechanism. The follower connecting column 21 is externally fixedly connected to the bottom side of the connecting limiting plate 17. A connecting reinforcing rod 3 is externally fixedly connected to each pair of cylinders 2 to strengthen the connection strength between the cylinders 2 and prevent the cylinders 2 from shaking and deforming during operation.

[0038] Through the connection of the reinforcing rod 3, multiple cylinders 2 can work together to ensure the smooth and reliable lifting and lowering movement of the supporting top plate 4. The top of the supporting base plate 1 is fixedly connected to the supporting telescopic column 22, which plays a guiding and supporting role. During the lifting and lowering process of the supporting top plate 4, the supporting telescopic column 22 can ensure the accurate movement direction of the supporting top plate 4 and prevent the supporting top plate 4 from shifting or tilting during the lifting and lowering process, thereby improving the stability and reliability of the entire supporting structure. The top of the supporting telescopic column 22 is fixedly connected to the bottom of the supporting top plate 4. The bottom of the supporting base column 15 is fixedly connected to the supporting anti-slip block 16. The bottom of multiple supporting rods 14 is fixedly connected to the top of the supporting anti-slip block 16. The bottom of two connecting limit plates 17 is slidably connected to the top of the supporting top plate 4. The outer bottom side of the sliding column 8 is slidably connected to the inside of the fixed base plate 10. The bottom of the sliding column 8 is slidably connected to the inner top of the supporting base plate 5. The outer side of the supporting rod 14 is fixedly connected to the inside of the supporting base column 15. The outer side of the reinforcing steel mesh 13 is fixedly connected to the inside of the supporting base column 15.

[0039] Working principle: First, during use, external forces and vibrations are transmitted to the bottom transmission column 6 through the support base plate 1. The connecting support block 7 pushes the telescopic spring 9 to slide inside the fixed chassis 10. At the same time, while absorbing shock and resisting pressure, the telescopic rubber block 23 and telescopic silicone pad 24 extend and retract at the bottom of the support base plate 1 to absorb shock and resist pressure. Meanwhile, the bottom of the support base plate 5 has support columns 15. Each support column 15 has a reinforcing column 11, a reinforcing steel plate 12, and a reinforcing steel mesh 13 inside. The cooperation of these elements distributes the pressure on the support base plate 1 and the support base plate 5, thereby achieving stable support. This not only ensures the stability of the bridge erecting machine's outriggers during dynamic operation, but also extends the structural life through the layered pressure-resistant design, ultimately achieving safe and reliable support under high-load conditions.

[0040] Secondly, the top of the supporting top plate 4 has a drive slide rail 20. In use, the two drive slide rails 20 are placed in opposite directions, so that the bridge erecting machine is supported by the connecting support frame 18 and the frame reinforcement plate 19. The two drive slide rails 20 drive the follower connecting column 21 to slide inside the connecting support frame 18. While the follower connecting column 21 is sliding, it drives the connecting limit plate 17 to slide outside the connecting support frame 18. Thus, when the cylinder 2 is in use, it is activated to adjust the height of the supporting top plate 4, so that it can be adjusted according to different heights, thereby limiting and fixing the bottom of the bridge erecting machine, effectively improving the self-adaptive ability of the support system, and ensuring that the support point is always in the optimal stress state.

[0041] 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.
