摘     要

 冷庫是發展冷藏業的基礎設施，也是在低溫條件下貯藏貨物的建筑群。食品保鮮主要以食品冷藏鏈為主，將易腐畜禽、水產、果蔬、速凍食品通過預冷、加工、貯存和冷藏運輸，有效地保持食品的外觀、色澤、營養成分及風味物質，達到食品保質保鮮，延長食品保存期的目的，起到調劑淡、旺季市場的需求并減少生產與銷售過程中經濟損耗的作用。冷庫作為食品低溫流通的中樞,近年來我國得到了顯著的發展,不僅建庫的規模和容量急劇增長,還表現在建庫技術上的現代化。
 由于冷庫內溫度低，作業環境惡劣，另一方面，大多數冷庫采用半沉入地下的形式，貨物需要提升取出,所以研制出一套符合冷庫工作要求、可靠的冷庫專用起重機具有重要和長遠的意義。該課題是源于目前企業的實際情況提出來的，全國有近萬家座冷庫,產品需求量大。該課題的研究對降低工人勞動強度，改善冷酷的正常運營意義重大，也有著廣闊的市場和應用前景。
 本論文介紹了該冷庫專用提升系統牽引機構的工作裝置的設計思路與過程。在該課題中所研制的冷庫專用提升系統牽引機構應當具有以下主要特點：（1）能適合工作在工作溫度為-35度左右,深度8m的冷庫工況下；（2）工作裝置要求具有較好的制動性能；（3）出貨門能夠在貨箱運動的帶動下開閉。根據上述的功能要求，本文作者在查閱了許多相關文獻資料并分析比較了國內外現有對冷庫專用起重機的研究的優缺點基礎上，確定了該工作裝置的設計方案并進行了相應的結構設計。
    本論文通過對國內外現狀的分析、方案設計、工作裝置的結構設計以及零部件的設計與計算等多方面闡述了該專用起重機的特點。

Abstract
 Cold Storage is the infrastructure in the developing of the refrigeration industry, but also is the buildings for storing goods in low-temperature conditions. Food preservation mainly linked to the main frozen food, perishable livestock and poultry, aquatic products, fruits and vegetables, instant food through the pre-cooling, processing, storage and refrigerated transportation, food effectively maintain the appearance, color, flavor and nutritional components, to achieve food shelf preservation, to extend the period of food preservation purposes, a swap short in the season the needs of the market and reduce the production and sales in the role of economic loss. Cold Storage, as a low-temperature food distribution hub in recent years, has been significant developed not only in building for the scale and capacity of rapid growth, but also in building the technical modernization.
   As lower temperature in cold storage, the poor working environment, on the other hand, most of cold storage into the semi-underground in the form of goods need to upgrade out，Therefore, the development of a reliable crane for the cold storage ,meeting cold storage requirements, is important and long-term significance. The Subject, put forward from the company actual situation at present, is widely demanded for the thousands of companies. The research in the subject is not only helpful to reduce labor intensity and to improve the normal operation, but also has a vast market and application.
 This paper introduced the cold storage for the work of crane equipment design ideas and processes. In the subject in the Development of cold storage crane should have the following main features: (1) could apply to work in temperatures of -35 degrees, the depth of 8 m of cold storage condition, (2) The device requires a better brake Performance (3) the door can be shipped in containers, driven movement opening and closing. According to the functional requirements, the author of this article available in a number of relevant literature and comparative analysis of the existing cold storage at home and abroad for study on the advantages and disadvantages of the crane on the basis of determining the device's design work and the corresponding structural design.
In this paper is about on the features of the crane by the status quo at home and abroad through the analysis, design, installation work and the structural design of parts of the design and calculation, and so on. .
