Description
技术领域technical field
本发明涉及平台支撑技术领域，具体而言，涉及一种不同角度的平台支撑。The invention relates to the technical field of platform support, in particular to a platform support with different angles.
背景技术Background technique
在电厂湿法脱硫工艺中常常需要对脱硫吸收塔进行维护与检修，因此就需要对脱硫吸收塔设立检修平台。由于所需检修平台极限跨距范围较大，因此必须对其设立支撑才能保证检修平台的稳定性。现有发电厂脱硫吸收塔的运行检修平台大多数都是生根在脱硫吸收塔上，利用脱硫吸收塔壁板预焊件或吸收塔加强筋设置三角支撑，且三角支撑的斜撑为单根钢构件。In the wet desulfurization process of power plants, it is often necessary to maintain and overhaul the desulfurization absorption tower, so it is necessary to set up a maintenance platform for the desulfurization absorption tower. Due to the large limit span range of the maintenance platform, it is necessary to set up supports to ensure the stability of the maintenance platform. Most of the operation and maintenance platforms of the desulfurization absorption tower in the existing power plant are rooted on the desulfurization absorption tower, and the triangular support is set up by using the pre-welded parts of the desulfurization absorption tower wall plate or the absorption tower reinforcement rib, and the diagonal brace of the triangular support is a single steel member.
在实际工况中，根据检修平台的安装以及检修设备的需求，检修平台的宽度约在1.8～3.0米的范围内。若检修平台的三角支撑中的斜撑为单根钢构件，检修平台的支撑计算中三角支撑的水平杆的挠度则达不到国家规范的要求，势必会存在各种安全隐患。In actual working conditions, according to the installation of the maintenance platform and the requirements of maintenance equipment, the width of the maintenance platform is about 1.8 to 3.0 meters. If the diagonal brace in the triangular support of the maintenance platform is a single steel member, the deflection of the horizontal bar of the triangular support in the calculation of the support of the maintenance platform will not meet the requirements of the national standard, and there will inevitably be various safety hazards.
发明内容Contents of the invention
为解决上述问题，本发明的目的在于提供一种不同角度的平台支撑，通过增加斜撑数量以及控制斜撑与水平杆之间的角度，使三角支撑的水平杆挠度满足国家规范要求，最终确保检修平台的安全性。In order to solve the above problems, the object of the present invention is to provide a platform support with different angles.

具体实施方式Detailed ways
下面通过具体的实施例并结合附图对本发明做进一步的详细描述。The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
如图1所示，本发明实施例所述的是一种不同角度的平台支撑，该平台支撑包括：As shown in Figure 1, what is described in the embodiment of the present invention is a platform support with different angles, and the platform support includes:
水平杆3，其一端垂直固定于脱硫吸收塔外壁上；Horizontal rod 3, one end of which is vertically fixed on the outer wall of the desulfurization absorption tower;
斜撑，其一端与脱硫吸收塔外壁连接，斜撑另一端与水平杆3连接，且斜撑至少设有两个，每个斜撑与水平杆3的夹角均不相等。One end of the diagonal brace is connected to the outer wall of the desulfurization absorption tower, and the other end of the diagonal brace is connected to the horizontal bar 3, and there are at least two diagonal braces, and the angle between each diagonal brace and the horizontal bar 3 is not equal.
水平杆3和斜撑共同组成了脱硫吸收塔检修平台的支撑结构。由于脱硫吸收塔检修平台跨度较大，设置至少两个斜撑可以分散水平杆3的受力，从而较仅有一个斜撑结构的检修平台要更加安全稳定。同时将每个斜撑与水平杆的夹角设置为不等，即所有斜撑均不平行，每个斜撑的受力均不相同。如此设置可以避免所有斜撑平行设置的不稳定性，不至于一个斜撑出现晃动而影响到其他斜撑，增加了整个平台支撑结构的稳定性。The horizontal bar 3 and the diagonal bracing together constitute the supporting structure of the maintenance platform of the desulfurization absorption tower. Since the maintenance platform of the desulfurization absorption tower has a large span, setting at least two diagonal braces can disperse the force of the horizontal bar 3, so it is safer and more stable than the maintenance platform with only one diagonal brace structure. At the same time, the included angles between each diagonal brace and the horizontal bar are set to be different, that is, all diagonal braces are not parallel, and the force of each diagonal brace is different. Such setting can avoid the instability of parallel setting of all diagonal braces, so that the shaking of one diagonal brace will not affect other diagonal braces, which increases the stability of the entire platform support structure.
进一步的，还包括格栅2，格栅2均匀设置于水平杆3上。水平杆3上设置格栅2可以方便工作人员行走，或方便检修设备、工具等的放置，增加了检修人员及设备的安全性。Further, the grid 2 is also included, and the grid 2 is uniformly arranged on the horizontal bar 3 . The grid 2 provided on the horizontal rod 3 can facilitate the walking of the staff, or facilitate the placement of maintenance equipment, tools, etc., which increases the safety of the maintenance personnel and equipment.
进一步的，斜撑设有两个，包括第一斜撑4和第二斜撑5。本实施例中设置了第一斜撑4和第二斜撑5两个斜撑，两个斜撑共同承担水平杆3的压力。从形式上将水平杆3分成了AB和BC两个计算段，由于AB段和BC段的长度均小于AC段的长度，因此AB和BC两个计算段的跨度均小于AC段的跨度，所以AB段和BC段的挠度均小于AC段的挠度，最终增加了水平杆3的稳定性。Further, there are two diagonal braces, including the first diagonal brace 4 and the second diagonal brace 5 . In this embodiment, two diagonal braces, the first diagonal brace 4 and the second diagonal brace 5 , are provided, and the two diagonal braces share the pressure of the horizontal bar 3 . Formally, the horizontal bar 3 is divided into two calculation sections AB and BC. Since the lengths of AB section and BC section are smaller than the length of AC section, the spans of AB and BC two calculation sections are smaller than the span of AC section, so The deflection of the AB section and the BC section is smaller than that of the AC section, which finally increases the stability of the horizontal bar 3 .
进一步的，斜撑与脱硫吸收塔外壁之间的连接和斜撑与水平杆3之间的连接均为刚性连接。采用刚性连接可以避免斜撑在水平杆3施加力时发生形变，从而增加了检修平台支撑结构的稳定性，提高了检修平台的安全性，降低了检修人员和检修设备的安全风险指数。Further, the connection between the diagonal brace and the outer wall of the desulfurization absorption tower and the connection between the diagonal brace and the horizontal bar 3 are both rigid connections. The use of rigid connections can prevent the diagonal brace from being deformed when the force is applied by the horizontal bar 3, thereby increasing the stability of the support structure of the maintenance platform, improving the safety of the maintenance platform, and reducing the safety risk index of maintenance personnel and maintenance equipment.
进一步的，斜撑选用工字钢或角钢。由于斜撑与脱硫吸收塔外壁之间的连接和斜撑与水平杆3之间的连接均为刚性连接，选用工字钢和角钢更加便于焊接等刚性连接，同时工字钢或角钢在支撑水平杆3时较其他型钢也具有更好的稳定性，不易发生形变。Further, the diagonal bracing is made of I-beam or angle steel. Since the connection between the diagonal brace and the outer wall of the desulfurization absorption tower and the connection between the diagonal brace and the horizontal bar 3 are all rigid connections, it is more convenient to use I-shaped steel and angle steel for rigid connections such as welding. Bar 3 also has better stability than other shaped steels, and is less prone to deformation.
进一步的，第一斜撑4与水平杆3的夹角为α，第二斜撑5和水平杆3的夹角为β，且α不等于β。α和β不等，可以使第一斜撑4和第二斜撑5受力不同，从而可以保证第一斜撑4和第二斜撑5不会同时产生晃动，至少会有一个斜撑对水平杆3发挥支承作用。Further, the angle between the first diagonal brace 4 and the horizontal rod 3 is α, the angle between the second diagonal brace 5 and the horizontal rod 3 is β, and α is not equal to β. α and β are not equal, which can make the first diagonal brace 4 and the second diagonal brace 5 bear different forces, so as to ensure that the first diagonal brace 4 and the second diagonal brace 5 will not shake at the same time, and there will be at least one pair of diagonal braces. The horizontal bar 3 plays a supporting role.
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
