Description
本发明涉及一种管道滚动支座，可广泛替代管道工程中的常规滑动或滚动支座，适用于允许管道沿管线方向产生水平位移且需尽可能减小管道水平位移时产生的摩擦力的管道支架，对于变形频繁、变形值较大、位移沿管线方向反复多变等条件下的管道支架特别适用，如供热管道、气力输送管道、给水管道等管道支架。本发明对于钢筋混凝土结构或钢结构管道支架均可适用。The invention relates to a pipeline rolling bearing, which can widely replace the conventional sliding or rolling bearing in pipeline engineering, and is suitable for a pipeline which allows the pipeline to generate horizontal displacement along the pipeline direction and needs to reduce the frictional force generated when the pipeline is horizontally displaced. The bracket is particularly suitable for pipeline supports under the conditions of frequent deformation, large deformation value, and repeated displacement along the pipeline direction, such as heating pipes, pneumatic conveying pipes, water supply pipes and the like. The invention is applicable to both reinforced concrete structures and steel structural pipe supports.
管道滑动支座和滚动支座是管道工程最常见的支座，二者均不允许管道有垂直位移但允许管道沿管线方向有水平位移。传统管道滑动支座的结构见图1，图2，其常规形式是滑动板作为滑动支座，在管道支架顶部设置垫板，然后将管道与管托焊接牢固，再将滑动板(通常采用聚四氟乙烯板)垫入管托与支架垫板之间。主要缺点是滑动板与管托或者支架垫板(材质一般是钢材)之间的摩擦力较大，并不是真正意义上的零摩擦力滑动。这是因为不同材料之间存在滑动摩擦力(摩擦力等于压力乘以摩擦系数，通常平整的钢板与钢板之间的滑动摩擦系数μ为0.3，钢板与聚四氟乙烯板之间的滑动摩擦系数μ为0.2)。当管道直径较粗、自身重量较大，或者管托、支架垫板发生锈蚀变的粗糙时，管道滑动支座水平移动所产生的滑动摩擦力还是相当大的。滑动摩擦力会水平作用于管道支架顶面，当管道支架越高，或水平摩擦力越大时，作用于支架柱身根部以及支架基础上的弯矩就会越大
(弯矩＝作用力×力臂，力臂即等于支架顶面到计算截面处的距离)。当弯矩较大时，支架柱身强度及支架基础尺寸取决于弯矩，而非作用于管道支架顶面的重量(垂直荷载)，支架柱身及基础的断面、配筋将明显加大，管道支架的综合造价亦相应增加。Pipe sliding supports and rolling bearings are the most common supports for pipe engineering, both of which do not allow vertical displacement of the pipe but allow horizontal displacement of the pipe in the direction of the pipeline. The structure of the conventional pipe sliding support is shown in Fig. 1, Fig. 2, and the conventional form is a sliding plate as a sliding bearing. A pad is placed on the top of the pipe bracket, and then the pipe and the pipe bracket are welded firmly, and then the sliding plate is usually used. The tetrafluoroethylene sheet is padded between the tube holder and the holder pad. The main disadvantage is that the friction between the sliding plate and the tube holder or the bracket plate (the material is generally steel) is large, and it is not a zero friction sliding in the true sense. This is because there is sliding friction between different materials (friction is equal to pressure multiplied by friction coefficient, the sliding friction coefficient μ between the usually flat steel plate and the steel plate is 0.3, and the sliding friction coefficient between the steel plate and the Teflon plate μ is 0.2). When the pipe diameter is relatively thick, its own weight is large, or the pipe support and the support plate are rough and rusted, the sliding friction generated by the horizontal movement of the pipe sliding support is still quite large. Sliding friction will act horizontally on the top surface of the pipe bracket. When the pipe bracket is higher, or the horizontal friction is greater, the bending moment acting on the root of the bracket and the foundation of the bracket will be larger.
(Bending moment = force × force arm, the arm is equal to the distance from the top surface of the bracket to the calculated section). When the bending moment is large, the strength of the bracket body and the foundation size of the bracket depend on the bending moment, not the weight acting on the top surface of the pipe bracket (vertical load), and the section and reinforcement of the bracket column and foundation will be significantly increased. The overall cost of the pipe support has also increased accordingly.
传统滚动支座结构见图3、图4、图5、图6，是由顶板14、顶板耳板16、底板15、底板耳板17、导轨18、辊子1、限位轴19等多个构件组成。安装时，需要先将顶板耳板、底板耳板、导轨分别焊接于顶板和底板上，然后将辊子1放置在底板上，再将限位轴19穿过底板耳板的限位孔栓接于辊子1两侧的圆心处，最后扣上顶板完成组装。这种滚动支座优点是：相对于滑动支座管道产生的水平摩擦力较小，一般来说钢辊与钢板之间的滚动摩擦系数μ取值为0.1，是相同条件下滑动支座水平摩擦力的一半。缺点是：滚动支座构件较多，且相互之间需焊接或组装，对各个构件的加工精度要求较高。辊子滚动面的中央需加工出一圈搁置导轨的凹槽，两端需加工出安装限位轴的螺孔，使得辊子制作要求较多的设备和工序。因此这种滚动支座加工制作较为复杂，造价较高，在管架工程中难以广泛使用。且这种滚动支座材料全部采用钢材料制作，易锈蚀。辊子发生损坏也难以维修或更换。The conventional rolling bearing structure is shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, and is composed of a top plate 14, a top plate ear plate 16, a bottom plate 15, a bottom plate ear plate 17, a guide rail 18, a roller 1, a limit shaft 19 and the like. composition. When installing, the top plate ear plate, the bottom plate ear plate and the guide rail are respectively welded to the top plate and the bottom plate, then the roller 1 is placed on the bottom plate, and then the limiting shaft 19 is bolted through the limiting hole of the bottom plate ear plate. At the center of both sides of the roller 1, the top plate is finally buckled to complete the assembly. The advantage of the rolling bearing is that the horizontal frictional force generated by the sliding bearing pipe is small, and generally the rolling friction coefficient μ between the steel roller and the steel plate is 0.1, which is the horizontal friction of the sliding bearing under the same conditions. Half of the force. The disadvantage is that there are many rolling bearing members, and they need to be welded or assembled with each other, and the processing precision of each member is high. The center of the rolling surface of the roller needs to be machined with a groove for resting the guide rail, and the screw holes for mounting the limiting shaft are to be machined at both ends, so that the roller requires more equipment and processes. Therefore, the processing of the rolling bearing is complicated and the cost is high, and it is difficult to be widely used in the pipe rack engineering. And the rolling bearing materials are all made of steel material, which is easy to rust. Damage to the rollers is also difficult to repair or replace.

参照图7-10所示，一种新型管道滚动支座，主要由辊子1，滚动支座顶板2，滚动支座耳板3，固定螺母4及调节螺栓5组成。辊子1的材质是聚四氟乙烯(传统的辊子无法采用聚四氟乙烯制作，材质只能是金属)，中部无需制作匹配辊子导轨的凹槽，其直径根据所承受管道的重量决定，管道越重，辊子的直径越大。辊子的长度则取决于管托的宽度，并且需保证管道在垂直方向的稳定性。一般而言，辊子的长度可等于管托的宽度。滚动支座顶板2采用钢板制成，厚度需满足在辊子的最大反力作用下不发生变形。滚动支座顶板的宽度要大于管托的宽度，以便于与管托的焊接，同时需满足放置辊子的空间要求。滚动支座顶板的长度要略大于管托7的长度，并且要略大于管道两个方向水平位移量的之和。滚动支座耳板采用钢板制成，共两个，分别垂直焊接于滚动支座顶板下面两侧，主要作用是对辊子进行限位，同时起到在安装或检修时用于支承调节螺栓的作用。滚动支座耳板的长度等于滚动支座顶板的长度，厚度根据其所承担的调节螺栓反力来
确定，高度不应小于辊子的半径，一般可取辊子直径的三分之二。在每个耳板的外侧下部两端焊接有与调节螺栓对应的螺母，共计四个,螺母用于安装调节螺栓。调节螺栓的规格需根据其所承担的管托传递下来的荷载确定，螺栓长度不小于辊子辊子直径的三分之二，并设通长螺纹。调节螺栓主要是在管道安装时发挥作用。由于安装时管托需要与滚动支座顶板相焊接，焊接时会产生高温，而聚四氟乙烯辊子不能耐高温，所以在焊接前聚四氟乙烯辊子不能先就位。这时可以通过将四个调节螺栓调整到合适高度，使得滚动支座顶板底面距离支架顶面略大于辊子的直径，并且保持支座顶板与支架顶面平行。然后进行管托与滚动支座顶板的焊接工作，待焊接完成且支座顶板冷却至自然温度时，再将聚四氟乙烯辊子放置在滚动支座正中间，且保证辊子的滚动方向与管线方向一致。再通过逐次向上拧动四个调节螺栓，使得滚动支座的顶板落于辊子上。最后将四个调节螺栓全部向上拧至极限，使得调节螺栓不影响滚动支座的正常滚动，最终完成安装工作。当辊子有破损需要更换时，可将四个调节螺栓逐次向下拧动，使得支座顶板轻微向上抬起，然后推出破损的辊子，换入新辊子，最后将四个调节螺栓逐次向上拧回原位，完成检修工作。(辊子放置在垫板上即可，不需固定)。Referring to Figures 7-10, a new type of pipe rolling support is mainly composed of a roller 1, a rolling bearing top plate 2, a rolling bearing ear plate 3, a fixing nut 4 and an adjusting bolt 5. The material of the roller 1 is PTFE (the traditional roller can not be made of Teflon, the material can only be metal), and there is no need to make a groove matching the roller guide in the middle, and the diameter is determined according to the weight of the pipe to be accepted. Heavy, the larger the diameter of the roller. The length of the roller depends on the width of the tube holder and the stability of the tube in the vertical direction is guaranteed. In general, the length of the roller can be equal to the width of the tube holder. The rolling support top plate 2 is made of steel plate, and the thickness is required to be deformed without the maximum reaction force of the roller. The width of the top plate of the rolling support is larger than the width of the tube holder to facilitate the welding with the tube holder, and at the same time, the space requirement for placing the roller is required. The length of the rolling support top plate is slightly larger than the length of the tube holder 7, and is slightly larger than the sum of the horizontal displacements in both directions of the pipe. The rolling bearing ear plates are made of steel plates, which are respectively welded to the lower sides of the top plate of the rolling support. The main function is to limit the rollers and play the role of supporting the adjusting bolts during installation or overhaul. . The length of the rolling bearing lug is equal to the length of the rolling support top plate, and the thickness is based on the adjusting bolt reaction force
It is determined that the height should not be less than the radius of the roller, and generally two-thirds of the diameter of the roller can be taken. A nut corresponding to the adjusting bolt is welded to both ends of the outer lower portion of each ear plate, and a total of four nuts are used for mounting the adjusting bolt. The specification of the adjusting bolt shall be determined according to the load transmitted by the pipe holder. The bolt length is not less than two-thirds of the diameter of the roller roller, and the long thread is provided. The adjusting bolts are mainly used when the pipe is installed. Since the tube holder needs to be welded to the top plate of the rolling support during installation, high temperature is generated during welding, and the Teflon roller cannot withstand high temperature, so the Teflon roller cannot be placed in place before welding. At this time, the four adjusting bolts can be adjusted to a suitable height so that the bottom surface of the rolling bearing top plate is slightly larger than the diameter of the roller from the top surface of the bracket, and the top plate of the supporting bracket is kept parallel to the top surface of the bracket. Then, the welding work of the tube support and the top plate of the rolling support is carried out. When the welding is completed and the top plate of the support is cooled to the natural temperature, the Teflon roller is placed in the middle of the rolling bearing, and the rolling direction and the pipeline direction of the roller are ensured. Consistent. Then, the four adjusting bolts are screwed up one by one, so that the top plate of the rolling bearing falls on the roller. Finally, the four adjusting bolts are all screwed up to the limit, so that the adjusting bolt does not affect the normal rolling of the rolling bearing, and finally the installation work is completed. When the roller needs to be replaced, the four adjusting bolts can be screwed down one by one, so that the top plate of the support is lifted up slightly, then the broken roller is pushed out, the new roller is replaced, and finally the four adjusting bolts are screwed up one by one. In-situ, complete the overhaul work. (The roller can be placed on the backing plate without fixing).
支架垫板10为钢板材质，其平面大小需根据滚动支座辊子的长度和滚动范围来确定。支架垫板表面需光滑平整，以减小与辊子之间的滚动摩擦系数。当管道支架为钢结构且顶面平面尺寸满足使用要求时，此时可将支架垫板省去。
The bracket pad 10 is made of a steel plate, and the plane size thereof is determined according to the length of the roller bearing roller and the rolling range. The surface of the bracket pad needs to be smooth and flat to reduce the rolling friction coefficient with the roller. When the pipe bracket is made of steel and the top plane dimension meets the requirements for use, the bracket pad can be omitted at this time.
