液壓貨梯的油缸的安裝要注意什么？

液壓貨運(yùn)電梯油缸的安裝方式有兩種:頂升和提升。頂升和提升的區(qū)別在于油缸放置方向相反，定性問(wèn)題，布置方便。缺點(diǎn)是油缸的有效使用提升相同荷載的提升機(jī)構(gòu)的油缸比頂升機(jī)構(gòu)大得多。

There are two ways to install the oil cylinder of the hydraulic freight elevator: jacking and lifting. The difference between jacking and lifting is that the oil cylinder is placed in the opposite direction, which is qualitative and easy to arrange. The disadvantage is that the effective use of the oil cylinder is much larger than that of the lifting mechanism for lifting the same load.

此外，提升機(jī)構(gòu)還需要設(shè)置強(qiáng)大的支撐架。因此，液壓貨運(yùn)電梯選擇頂升機(jī)構(gòu)或提升機(jī)構(gòu)不能一概而論，而應(yīng)根據(jù)提升機(jī)的工況進(jìn)行選擇。一般來(lái)說(shuō)，對(duì)于提升載荷大、升降高度小的場(chǎng)合，應(yīng)選擇頂升機(jī)構(gòu)，對(duì)于載荷小但升降高度大的場(chǎng)合，應(yīng)選擇提升機(jī)構(gòu)。根據(jù)頂升初始結(jié)構(gòu)，為了滿足穩(wěn)定性要求，增加油缸的尺寸和提升式，為了達(dá)到與頂升蘇力相同的有效面積，增加油缸。如果后者較大，應(yīng)選擇頂升機(jī)構(gòu)。

In addition, the lifting mechanism also needs to be equipped with a strong support frame. Therefore, the selection of lifting mechanism or lifting mechanism for hydraulic freight elevator cannot be generalized, but should be based on the working conditions of the elevator. Generally speaking, the lifting mechanism should be selected for the occasions with large lifting load and small lifting height, and the lifting mechanism should be selected for the occasions with small load and large lifting height. According to the initial structure of jacking, in order to meet the stability requirements, increase the size and lifting type of the oil cylinder, and increase the oil cylinder in order to achieve the same effective area as the jacking force. If the latter is large, the jacking mechanism should be selected.

此外，布局是否方便也是一個(gè)非常重要的問(wèn)題。例如，在較大或波浪較高的地方，使用頂升機(jī)構(gòu)會(huì)存在布局問(wèn)題。此時(shí)，為了便于布置和防止液壓貨梯缸被波浪侵蝕，應(yīng)選擇提升結(jié)構(gòu)來(lái)確定油肩安裝位置，因?yàn)闃蛄旱牡觞c(diǎn)在提升過(guò)程中不是一條直線。因此，氣缸在提升過(guò)程中會(huì)擺動(dòng)，因此氣缸兩端與其他部件的連接必須是同一方句的鉸接。此外，液壓貨梯缸的安裝方法是尾吊耳式、中間銷(xiāo)軸式還是頭銷(xiāo)軸式也必須經(jīng)過(guò)比較和計(jì)算后確定。

In addition, whether the layout is convenient is also a very important issue. For example, in places with large or high waves, there will be layout problems when using the jacking mechanism. At this time, in order to facilitate the arrangement and prevent the hydraulic cargo elevator cylinder from being eroded by waves, the lifting structure should be selected to determine the installation position of the oil shoulder, because the lifting point of the bridge is not a straight line during the lifting process. Therefore, the cylinder will swing in the lifting process, so the connection between the two ends of the cylinder and other components must be the same square hinge. In addition, the installation method of hydraulic cargo elevator cylinder must be determined after comparison and calculation.

主要優(yōu)點(diǎn)是氣缸有效面積大，整機(jī)安裝高度低。缺點(diǎn)是如果氣缸行程較大，氣缸存在穩(wěn)定性問(wèn)題，然后氣缸布局困難。液壓貨梯提升式機(jī)構(gòu)主要優(yōu)點(diǎn)是沒(méi)有穩(wěn)傳安裝架的高度士勘口，因此，在落差物大的地方可以考慮用這種形式。

The main advantages are large effective area of the cylinder and low installation height of the whole machine. The disadvantage is that if the cylinder stroke is large, the cylinder has stability problems, and then the cylinder layout is difficult. The main advantage of the hydraulic cargo elevator lifting mechanism is that it has no stable transmission mounting frame, so it can be considered in places with large drop.

頭部乍聾油式可使安裝加的高度降低，但如果較大時(shí)，油缸會(huì)因?yàn)樘嵘吲炜丙愂芰υ黾?，而且提升高度越大，這種增力國(guó)濺快，這對(duì)油缸的使用是不禾喲，所以太大時(shí)，頭部銷(xiāo)軸式不適用。為了綜合考慮安裝架的高度和油缸在提升過(guò)程中受力的問(wèn)題，可以考慮中間式的安裝方式，安裝位置可以根據(jù)計(jì)算設(shè)置在適當(dāng)?shù)母叨壬稀?/div>

The head sudden deafening oil type can reduce the installation height of the oil tank, but if it is large, the force of the oil tank will increase due to the lifting height, and the higher the lifting height, the faster the force increase will be, which is not suitable for the use of the oil tank, so the head pin type is not applicable when it is too large. In order to comprehensively consider the height of the mounting frame and the stress of the oil cylinder during the lifting process, the intermediate installation method can be considered, and the installation position can be set at the appropriate height according to the calculation.
