【正文】 停車板的實際運行速度，當上停車板的運行速度達到或超過設定的極限值時（一般為額定速度的115%以上），限速器停止運轉，并借助繩輪中的摩擦力或夾繩機構提拉拉桿，通過機械動作發(fā)出信號，切斷控制電路，使上停車板強行制停在立柱上，所以限速器是在上停車板超速并達到臨界值時起監(jiān)測及操縱作用。設計中的限速器安裝在立柱頂上。 限速器裝置由限速器、鋼絲繩和張緊裝置組成。鋼絲繩的兩端分別繞過限速器和張緊裝置的繩輪形成一個封閉的環(huán)路后，固定在導向板安全鉗的繩頭拉手上，該拉手能提拉起安全鉗連桿系統(tǒng)。使兩導向板內側的安全鉗楔塊撐緊導槽，是超速下落的上停車板被迫制停。在安全鉗動作的同時，其提拉桿操縱安全開關，使控制電路斷開。只有當所有安全開關復位后，釋放安全鉗，上停車板才能恢復正常的使用。3）緩沖器緩沖器是上停車板極限位置的最后一道安全裝置。當所有保護措施都失效時，帶有較大速度與能量的上停車板便會沖向底層，造成嚴重后果。因此必須設置緩沖器以吸收、消耗上停車板能量，減少損失。彈簧緩沖器也稱蓄能型緩沖器，由緩沖橡皮、緩沖座、壓縮彈簧和緩沖彈簧座等部分組成，當彈簧緩沖器受到撞擊時，彈簧會發(fā)生變形，于是將上停車板下落時產生的動能與勢能轉化為彈性變形能，是上停車板下落時得到緩沖、減速。安裝時將4個彈簧緩沖器分別安裝在上停車板四角邊緣的正下方的地面上。第七章 軟件設計 梯形圖 43 語句表基于PLC控制的立體停車庫設計Network 1 // Network Title// 系統(tǒng)啟動停止程序LD EU= Network 2 LD AN LDN A OLD= Network 3 LD O = Network 4 LSCR Network 5 // 判斷停車取車程序LD A O AN SCRT Network 6 LD A O AN SCRT Network 7 SCRENetwork 8 // 存車LSCR Network 9 LD A A A LPSAN SCRT LRDA AN SCRT LRDA A AN SCRT LPPA A A SCRT Network 10 SCRENetwork 11 // 存車LSCR Network 12 // 4車板右移LD AN = Network 13 // 1車板下降LD AN AN = Network 14 // 1車板上升LD O AN A AN = Network 15 // 4車板復位LDN = Network 16 LD SCRT Network 17 SCRENetwork 18 LSCR Network 19 // 2車板下降LD AN AN = Network 20 // 2車板上升LD O A A AN = Network 21 // 4車板復位LDN = Network 22 LD SCRT Network 23 SCRENetwork 24 LSCR Network 25 // 6車板左移LD AN = Network 26 // 3車板下降LD AN AN = Network 27 // 1車板上升LD O AN A AN = Network 28 // 6車板復位LDN = Network 29 LD SCRT Network 30 SCRENetwork 31 // 取車程序LSCR Network 32 LD LPSA SCRT LRDA SCRT LPPA SCRT Network 33 SCRENetwork 34 // 1車位取車LSCR Network 35 LD LPSAN AN = LPPA AN = Network 36 LD TON T41, 100Network 37 LD T41AN = Network 38 LD O AN = Network 39 LDN A A = Network 40 LD SCRT Network 41 SCRENetwork 42 // 2車位取車LSCR Network 43 LD AN = Network 44 LD O AN = Network 45 LD SCRT Network 46 SCRENetwork 47 // 3車位取車LSCR Network 48 LD LPSAN AN = LPPA AN = Network 49 LD TON T42, 100Network 50 LD T42AN = Network 51 LD O AN = Network 52 LDN A A = Network 53 LD SCRT Network 54 SCRE
47總結與展望經過一個多月的立體停車庫設計，我對電器PLC原理及設計，電器控制等知識有了更深的理解。同時學到了很多東西，增加了自己的知識積累，相信會對自己以后的學習和工作有所幫助。通過設計，完成了立體車庫信息的搜集，立體車庫設計方案的提出、選擇及論證，輸入及輸出設備及PLC的選用，及其外接設備的線路連接以及PLC程序編寫。在王老師的指導下順利地完成了論文格式的書寫。在設計中遇到了一些新的問題，但應該采取積極的措施進行解決。同時在設計中也有一些問題沒有考慮全面，但我相信自己在進入本科階段學習后仍會不斷努力，將PLC學得更好。 立體停車庫的控制系統(tǒng)可以加入相應的自動收費系統(tǒng)，自動檢測等系統(tǒng)。如果對于停車位較多的情況可以設計相應的自動引導停車裝置及系統(tǒng)等，使立體停車庫的功能更加完善。并且在我國，機械式立體停車庫的研究仍處于起步階段，隨著城市用地面積緊張和汽車已進入大多數百姓家，因此僅靠地面停車是遠遠不夠的，可以說立體停車庫研制在我國具有廣闊的前景。致謝這次畢業(yè)設計對我有很大的意義，它是我終生難忘的一段路程。在設計中遇到了很多的問題，但是最終完成了畢業(yè)設計。感謝母校給我們提供的這次難得機會，使我可以對三年來所學有一個更深的認識。在這一個多月的時間里，自己要一邊復習功課，一邊做畢業(yè)設計，有時時間很緊張。在設計中遇到了一些困難，但在王老師的指導下，一些困難順利的解決。從老師身上，我明白到自己的不足，以及以后努力的方向。同時此次設計是對自己所學知識的又一次強化。老師你們淵博的知識，嚴謹的治學態(tài)度，使我更加強了所學與實踐的結合。感謝你們熱心教導。同時感謝幫助過我的同學，在我遇到問題時我們積極的在一起討論，你們給我提供意見，更加豐富了自己的思路。謝謝你們的幫助。最后衷心的感謝各位老師在這段時間里對我的教導！附錄 英文資料Mechanical stereo garageMechanical stereo garage owns a number of innovative design and technology which can greatly increase the parking scheme operating ine also provides the vehicles with a high capacity, highly intensive storage, security, environmental protection, ideal for fast and convenient access to parking space. Comprehensive settlement of the difficult to , chaotic parking problems ,it opened up a new concept of the ideal parking solution in the parking area. It can save a lot of land area, the limited land resources to be reasonably fully utilized to address the parking and greening, landscaping and construction of the contradiction between the urban landscape, significantly improve the level of urban operations and urban management level, and its prospects for urban management is extremely broad. ：Stereo garage is the storage which is used for automatic parking and scientific storage of kinds of automobile. As the quantity of urban automobile has increased continuously in nowadays ,the hardtopark problem has bee a mon phenomenon. Mechanical stereo garage can use land resource sufficiently and bring space advantage into play,and maximize the number of parking cars. It has bee an important way for static traffic problem of cities. The issue studies the type mechanical parking system which named updown and translation stereo garage, and regards of the two factors of manufacture and operational efficiency synthetically.With the rapid development of cities,the settlement of the difficulty of parking of cities has already reached the very urgent stage. In the city center where every inch of land is precious ,especially the area which such vehicles as the hotel ,market ,shopping center location,etc. :concentrate,can only develop to the sky,to underground,so has built and already to a great deal of threedimensional garage parkings reached the essential stage. The garage can both be installed with ground and underground,the greatest advantage can fully utilize the small area to develop to the high altitude, try one39。s best to store more vehicles,the place that the land
