Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of beam-column restraint and shock absorption, and in particular relates to a beam-column restraint and shock absorption device. Background Art
[0002] Belt conveyors play a vital role in the comprehensive mechanized production of coal mines. They enable the continuous and stable transportation of large quantities of coal, significantly improving production efficiency. Compared with traditional manual transportation methods, belt conveyors can handle coal at higher speeds and with larger transport volumes, ensuring a smooth production process. They can significantly reduce manpower requirements, minimizing the risks and labor intensity of manual operations. This not only improves safety but also allows workers to focus on more critical production processes, thereby improving overall work efficiency. They can be flexibly configured to suit the actual conditions of the mine and can operate in complex terrain, including varying heights, inclination angles, and turning radii. This adaptability enables them to effectively cope with changing mine environments and transportation needs; therefore, belt conveyors are an indispensable transportation tool in the comprehensive mechanized production of coal mines in my country.
[0003] However, due to limitations in coal mine shaft design and conveying capacity, multiple conveyors are often required to operate in concert, leading to the emergence of transfer stations at varying heights and angles. Mine transfer stations generate significant vibration during operation, especially when certain equipment is installed on the second floor or higher. This can negatively impact the building, necessitating effective vibration control to ensure proper operation of the equipment.
[0004] Existing shock-absorbing devices are not flexible enough, easily damage the original structure, and have poor adaptability. Utility Model Content
[0005] In view of this, the utility model provides a beam-column restrained shock absorber, which can solve the problems of the existing shock absorbing device being insufficiently flexible, easily damaging the original structure, and having poor adaptability.
[0006] The utility model is achieved in this way:
[0007] The utility model provides a beam-column constraint shock absorber, which includes a fixed steel plate, a shock-absorbing ball and a damping filling layer, the fixed steel plate is a spherical structure, and the two side positions in contact with the beam and column are set as a plane structure, which is fixed to the surface of the beam and column by bolts; the interior of the fixed steel plate is set as a hollow structure, and mounting holes are opened at corresponding positions on both sides close to the beam and column; the main body of the shock-absorbing ball is a spherical structure, which is arranged inside the hollow structure of the fixed steel plate, and fixing rods are provided on both sides close to the beam and column, one end of the fixing rod is fixedly connected to the spherical body of the shock-absorbing ball, and the other end passes through the mounting hole and is fixedly connected to the corresponding position of the beam and column; the damping filling layer is filled between the fixed steel plate and the shock-absorbing ball, and the damping filling layer is used to consume vibration energy to constrain and damp the beam and column.
[0008] On the basis of the above technical solution, the beam-column restraint shock absorber of the present invention can also be improved as follows:
[0009] The hollow structure inside the fixed steel plate is an irregular spherical structure, the size of which is larger than that of the shock-absorbing ball.
[0010] Furthermore, the two fixing rods are respectively fixed perpendicularly to the connected beam columns.
[0011] Furthermore, an elastic layer is fixed on the inner wall of the fixed steel plate and the outer wall of the spherical body of the shock-absorbing ball, and the vibration force is offset by the reverse force of the contact between the elastic layer and the shock-absorbing ball.
[0012] Furthermore, a rubber sealing pad is provided at the position where the fixing steel plate is connected to the fixing rod of the shock-absorbing ball, so as to prevent moisture from entering the interior of the fixing steel plate.
[0013] Furthermore, the elastic layer includes a butterfly spring layer and a polyurethane layer wrapped on the outside, so as to adapt to different vibration loads.
[0014] Furthermore, in the initial state, the spherical body of the shock-absorbing ball has a contact area of at least 3 square centimeters with the inner wall of the fixed steel plate.
[0015] Furthermore, the outer wall of the fixed steel plate away from the side of the beam column is in a spherical arc shape for dispersing wind force.
[0016] Furthermore, the elastic layer is fixedly connected to the inner wall of the fixed steel plate and the outer wall of the spherical body of the shock-absorbing ball by bolts.
[0017] Furthermore, the damping filling layer is made of shape memory alloy.
[0018] The benefits of this improved solution include: the spherical design of the fixing plate enhances stability and provides a larger contact area. Bolted to the beam and column surface, it ensures stability. The interior is hollow, providing space for the shock-absorbing balls.
[0019] The spherical shape of the damping ball allows for flexible movement to adapt to vibrations in different directions. The fixing rods on both sides ensure a stable connection between the damping ball and the beam, preventing displacement. This displacement absorbs and disperses vibration energy, enhancing the shock absorption effect.
[0020] The damping infill layer dissipates vibration energy and reduces vibration transmission. Shape memory alloy is used to enhance energy dissipation. It works in conjunction with the fixed steel plate and damping balls to improve the seismic resistance of beams and columns.
[0021] The elastic layer counteracts vibrations through a counteracting force, further reducing their impact. It can be adjusted to suit different vibration loads, increasing flexibility.
[0022] Rubber seals block moisture ingress, protecting internal components and extending service life.
[0023] The outer wall of the fixed steel plate is designed in a spherical arc shape, which helps to disperse wind force and reduce the impact of wind pressure.
[0024] Compared with the prior art, the beam-column restraint shock absorber provided by the present invention has the following beneficial effects:
[0025] The anchoring steel plate serves as the base support structure. Bolted to the beam and column surfaces, it provides a stable connection, ensuring the shock absorber does not move under vibration. Its spherical shape, with flat sides, increases the contact area and ensures effective resistance to vibration loads. The hollow structure increases the movement of the shock absorber ball, allowing it to move freely when subjected to external forces, thereby enhancing the shock absorption effect. Mounting holes are provided on both sides near the beam and column to facilitate the installation of the fixing rod and ensure a secure connection between the shock absorber ball and the beam and column.
[0026] The shock-absorbing ball is a spherical structure that can deform freely in multiple directions under vibration, helping to disperse and absorb vibration energy. The ball's fixing rod is fixed to the ball at one end and secured to the beam or column through a mounting hole at the other end, ensuring effective force transmission during vibration. The design of the shock-absorbing ball allows for a certain degree of elastic deformation, allowing it to better adapt to different vibration loads, thereby improving the overall shock absorption effect.
[0027] The damping infill layer, located between the fixed steel plate and the damping balls, dissipates vibration energy and reduces its transmission. Made of a shape-memory alloy, this material automatically adjusts its shape under varying stress conditions, providing a continuous damping effect. By dissipating vibration energy, the damping infill layer effectively reduces the vibration response of beams and columns, thereby extending the service life of the structure.
[0028] The elastic layer, comprised of a butterfly spring layer and an outer polyurethane coating, is designed to adapt to varying vibration loads. By contacting the spherical body of the damping ball and the inner wall of the fixed steel plate, the elastic layer generates a counteracting force, counteracting vibration and further enhancing the shock absorption effect.
[0029] The rubber seal is installed at the connection between the fixed steel plate and the shock absorber ball fixing rod. It is mainly used to prevent moisture from entering the fixed steel plate, preventing corrosion and damage. It protects the performance and life of internal components and ensures the stability of the shock absorber in various environmental conditions.
[0030] The outer wall of the fixed steel plate away from the side of the beam and column is designed in a spherical arc shape, which can effectively disperse the impact of wind and other external forces, help reduce the direct effect of wind pressure on the structure, and thus increase the stability and safety of the structure.
