【摘要】：隨著工程設(shè)備大型化、重型化的發(fā)展,上千噸的工程設(shè)備已屢見不鮮,而保證這些大型設(shè)備的安全吊裝就顯得越來越重要。大型塔設(shè)備的吊裝一般采用兩臺(tái)重型起重機(jī)配合抬吊的方法,在這種吊裝方法中設(shè)計(jì)者需要設(shè)計(jì)主尾吊點(diǎn)吊耳及局部加強(qiáng)結(jié)構(gòu)。 根據(jù)塔設(shè)備既長(zhǎng)又重的特點(diǎn),一般選取軸式吊耳配合尾部吊耳來完成吊裝。然而設(shè)計(jì)標(biāo)準(zhǔn)中軸式吊耳的最大承重為200t,采用標(biāo)準(zhǔn)中軸式吊耳無法滿足重型塔設(shè)備的吊裝,因此現(xiàn)在對(duì)于重型塔設(shè)備吊耳一般都需要進(jìn)行非標(biāo)設(shè)計(jì)。吊耳的非標(biāo)設(shè)計(jì)主要參照標(biāo)準(zhǔn)軸式吊耳的基本結(jié)構(gòu)形式,根據(jù)具體吊裝特點(diǎn)為軸式吊耳設(shè)計(jì)一些加強(qiáng)結(jié)構(gòu),選擇合適的吊耳結(jié)構(gòu)尺寸,從而初步得到滿足吊裝的非標(biāo)吊耳。接下來需要對(duì)所設(shè)計(jì)非標(biāo)吊耳以及主尾吊點(diǎn)局部的加強(qiáng)結(jié)構(gòu)還有塔設(shè)備本身進(jìn)行強(qiáng)度校核,本文采用ANSYS軟件進(jìn)行有限元分析,根據(jù)得到的應(yīng)力變形結(jié)果對(duì)結(jié)構(gòu)強(qiáng)度進(jìn)行校核,最終確定所設(shè)計(jì)的非標(biāo)吊耳及局部加強(qiáng)結(jié)構(gòu)是否滿足相應(yīng)塔設(shè)備的安全吊裝。 本文主要研究的是為某重型塔設(shè)備設(shè)計(jì)吊耳及局部加強(qiáng)結(jié)構(gòu)；對(duì)所設(shè)計(jì)的非標(biāo)吊耳、局部加強(qiáng)結(jié)構(gòu)及塔設(shè)備本身進(jìn)行強(qiáng)度校核,評(píng)估吊耳及局部加強(qiáng)結(jié)構(gòu)是否滿足重塔的安全吊裝；對(duì)軸式吊耳進(jìn)行優(yōu)化分析,得到軸式吊耳軸壁厚度、吊耳軸徑以及吊耳井字筋板間距對(duì)軸式吊耳強(qiáng)度的影響規(guī)律,同時(shí)還對(duì)所設(shè)計(jì)的局部加強(qiáng)結(jié)構(gòu)進(jìn)行了優(yōu)化分析。
[Abstract]:With the development of large-scale and heavy-duty engineering equipment, thousands of tons of engineering equipment has become common. However, it is more and more important to ensure the safety of these large equipment. Generally, two heavy cranes are used to hoist the large tower equipment. In this method, the designer needs to design the main-tail hoist and the local strengthening structure. According to the characteristics of long and heavy tower equipment, the shaft hoist is usually selected to complete the hoisting with the tail hoist. However, the maximum bearing capacity of the axle hoist in the design standard is 200t. The standard shaft hoist cannot satisfy the lifting of heavy tower equipment. Therefore, it is generally necessary to carry out non-standard design for the lifting lugs of heavy tower equipment. The non-standard design of the hoists mainly refers to the basic structure of the standard shaft hoists. According to the characteristics of hoisting, some strengthening structures are designed for the axle-type hoists, and the appropriate dimensions of the hoisting lugs are selected. Therefore, the non-standard hoisting gear can be preliminarily obtained. Then, the strength check of the designed non-standard hoist and the local strengthening structure of the main tail lifting point as well as the tower equipment itself should be carried out. In this paper, the finite element analysis is carried out with ANSYS software, and the strength of the structure is checked according to the result of stress and deformation. Finally, it is determined whether the designed non-standard hoist and local reinforcement structure meet the safety lifting of the corresponding tower equipment. This paper mainly studies the design of hoist and local strengthening structure for a heavy tower equipment. The strength of the designed non-standard hoist, the locally strengthened structure and the tower equipment itself is checked, and the safety hoisting of the heavy tower is evaluated. The influence of shaft wall thickness, diameter of shaft and spacing of bezel plate on the strength of shaft suspension was obtained by optimizing analysis of the shaft hoist. 3. The influence of the shaft wall thickness, the diameter of the shaft and the spacing of the sash plate on the strength of the shaft suspension were obtained. At the same time, the design of the local strengthening structure is optimized and analyzed.
