It is mainly used for the support of thermal pipes and equipment in ships, thermal power plants, nuclear power plants and chemical refineries.
管道支架结构的设计和形式选用是管道系统设计中的一个重要组成部分,支架除支撑管道重量外,还可以平衡管系作用力,限制管道位移和吸收震动,在管道系统设计时,正确选择和布置结构合理的支架,能够改善管道的应力分布和作用力,确保管道系统安全运行,并延长其使用寿命。The design and form selection of the pipeline support structure is an important part of the pipeline system design. In addition to supporting the weight of the pipeline, the support can also balance the force of the pipeline system, limit the displacement of the pipeline and absorb vibration. When designing the pipeline system, the correct selection and Arrangement of structurally reasonable supports can improve the stress distribution and force of the pipeline, ensure the safe operation of the pipeline system, and prolong its service life.
变力支架主要用于有垂直位移的动力管道或设备的支承。目前市面上已经应用的变力支架，其内装有圆柱螺旋弹簧，在承载的同时，它能适应管道或设备的热位移，也能吸收管道的振动，可以同时起到减振作用。The variable force support is mainly used for the support of power pipelines or equipment with vertical displacement. At present, the variable force support that has been used in the market is equipped with a cylindrical helical spring. While carrying the load, it can adapt to the thermal displacement of the pipeline or equipment, and can also absorb the vibration of the pipeline, which can also play a role in vibration reduction.
但是由于其主要依靠弹簧力来支承荷载，因此现有的变力弹簧支架只适宜用在需要减少垂直方向应力，且垂直位移较小的场合。But because it mainly relies on the spring force to support the load, the existing variable force spring support is only suitable for use in occasions where it is necessary to reduce the stress in the vertical direction and the vertical displacement is small.

The three-way variable-force vibration-damping bracket based on the metal-rubber pipeline includes an upper pipe clamp and a lower pipe clamp for clamping and fixing the pipeline. The lower part of both ends of the lower pipe clamp is fixed with a cover-shaped shell, and the inner cover of the shell is provided with a base with a hollow shell-shaped upper boss, and the upper surface of the hollow shell-shaped upper boss has perforations. The inner bottom of the shell is provided with a lower boss that passes through the perforation and penetrates into the body of the hollow shell-shaped upper boss. The circumference of the lower boss is provided with several elastic thimbles. Hollow cylindrical metal rubber is set between the inner peripheral walls; when working, the hollow cylindrical metal rubber is inserted into the outer periphery of the hollow shell-shaped upper boss, the elastic thimble is installed on the circumference of the lower boss, and then the cover-shaped outer shell is covered Insert the hollow cylindrical metal rubber periphery, and compress the elastic thimble at the same time, so that the elastic thimble can pass through the perforation, and finally put the pipe between the upper pipe clamp and the lower pipe clamp and lock it.
本发明锥型导向杆6端部设置一带有弹性的滚珠结构，由于带有弹性，能够保证滚珠始终与底座内壁面保持接触，滚珠可以在锥型结构中自由滚动，用以降低上管夹1与底座4内壁之间相对运动的摩擦力。空心圆柱金属橡胶8与圆柱螺旋弹簧9的组合体具有一定压缩量，可以降低由于管道振动所带来的X、Z方向的应力和位移，从而达到减振的目的。且外壳3中心部分与底座4顶端之间留有足够的余量，确保在发生振动时其相互之间不会发生碰撞及干涉。外壳3顶部设置有4个螺栓孔，用于与连接件2的连接，连接件2的主要用途在于将上管夹1、下管夹6和外壳3进行固接，并且连接方式都选择螺栓连接，保证后期在进行更换或维修时拆卸便利。The end of the tapered guide rod 6 of the present invention is provided with an elastic ball structure, which can ensure that the ball is always in contact with the inner wall of the base, and the ball can roll freely in the tapered structure to lower the upper pipe clamp 1 The frictional force relative to the inner wall of the base 4. The combination of hollow cylindrical metal rubber 8 and cylindrical helical spring 9 has a certain amount of compression, which can reduce the stress and displacement in X and Z directions caused by pipeline vibration, so as to achieve the purpose of vibration reduction. And there is enough margin between the central part of the shell 3 and the top of the base 4 to ensure that they will not collide and interfere with each other when vibration occurs. There are 4 bolt holes on the top of the shell 3, which are used to connect with the connecting piece 2. The main purpose of the connecting piece 2 is to fasten the upper pipe clamp 1, the lower pipe clamp 6 and the shell 3, and the connection method is bolt connection. , to ensure that it is convenient to disassemble when replacing or repairing later.
在底座4外壁布置有一空心圆柱金属橡胶5，其特征在于组合体不与外壳3及底座4直接固接，而仅通过底座4外表面进行定位。空心圆柱金属橡胶5具有较大的刚度，可以在一定程度上提供满足支撑刚度的需求。底座4外表面安装空心圆柱金属橡胶5后，其组合体外径仍略小于外壳3内壁直径，保证空心圆柱金属橡胶5在压缩时具有一定变形的空间。A hollow cylindrical metal rubber 5 is arranged on the outer wall of the base 4 , which is characterized in that the combination is not directly fixed to the shell 3 and the base 4 , but is only positioned through the outer surface of the base 4 . The hollow cylindrical metal rubber 5 has relatively high rigidity, which can meet the requirement of supporting rigidity to a certain extent. After the hollow cylindrical metal rubber 5 is installed on the outer surface of the base 4, the combined outer diameter is still slightly smaller than the inner wall diameter of the shell 3, so that the hollow cylindrical metal rubber 5 has a certain deformation space when compressed.
本发明具有以下几个优点：The present invention has the following advantages:
1）相较于传统的变力支架只能衰减的垂直方向应力的缺点，本支架在内部结构上加入了X、Z方向的减振装置，从而实现了同时承受X、Y、Z三方向的应力和位移的功能。1) Compared with the disadvantage that the traditional variable force support can only attenuate the vertical stress, this support has added vibration-reducing devices in the X and Z directions to the internal structure, so as to realize the simultaneous bearing of X, Y and Z directions. Functions of stress and displacement.
2）同仅依靠弹簧支承载荷的传统变力支架相比，本发明支架在结构中加入了金属橡胶元件，由不锈钢金属丝编织冲压而成的空心圆柱型金属橡胶7既保留了金属材料耐磨、耐腐蚀的性能，并具备高分子材料相同的可压缩性，且在拉压过程中会通过内部金属丝之间的相互摩擦及挤压运动实现对冲击以及振动能量的吸收。同时又兼具一定的支撑刚度。克服了传统变力支架只能承受较小的应力和位移量的缺点，并且相同的使用条件下，其性能更优越，抵抗破坏的能力更强。2) Compared with the traditional variable force support that only relies on springs to support the load, the support of the present invention adds metal rubber components to the structure, and the hollow cylindrical metal rubber 7 formed by braiding and stamping stainless steel wire not only retains the wear resistance of metal materials , corrosion resistance, and have the same compressibility as polymer materials, and absorb impact and vibration energy through the mutual friction and extrusion movement between internal metal wires during the tension and compression process. At the same time, it has a certain support rigidity. It overcomes the shortcomings of the traditional variable force support that can only bear small stress and displacement, and under the same use conditions, its performance is superior and its ability to resist damage is stronger.
