【摘要】：隨著城市汽車保有量的不斷增加，停車難已經(jīng)成為當(dāng)今社會高度關(guān)注和政府亟待解決的問題。城市的發(fā)展使得土地彌足珍貴，要為解決停車難問題而規(guī)劃出足夠的地上停車面積是一件兩難的事情，而發(fā)展地下停車空間無疑是解決這一難題的有效途徑。 深井式立體智能車庫是一種建造于地下的光機電液計一體化立體停車設(shè)備，其先進的結(jié)構(gòu)設(shè)計和布局能彌補現(xiàn)行其它形式立體車庫存在的占地面積大、能耗高、噪聲大、存取車時間長、不易組合形成車庫群等方面的不足，有效地解決停車環(huán)境與城市規(guī)劃之間的矛盾。在深井式立體智能車庫的研制和試運行過程中，，發(fā)現(xiàn)其自行式升降平臺易因偏載產(chǎn)生“悶車”現(xiàn)象，這會嚴(yán)重影響該類車庫的可靠運行及推廣應(yīng)用。 本文針對深井式立體智能車庫的“悶車”現(xiàn)象，以PSC8CK-4ZT型車庫為藍本，在優(yōu)化了升降平臺桁架焊接結(jié)構(gòu)、有效控制了升降系統(tǒng)的制造和安裝精度的基礎(chǔ)上，剖析出偏載造成液壓馬達的啟動阻力過大、輸出功率大大超出其出廠設(shè)置值是悶車現(xiàn)象的主要原因，比較分析現(xiàn)行同步方案等，采用移植創(chuàng)造和組合創(chuàng)新的方法，研制出具有結(jié)構(gòu)簡單、同步響應(yīng)速度快、穩(wěn)定性好以及可靠性高等特點和優(yōu)勢的齒輪齒條消隙式剛性同步機構(gòu)。進一步通過結(jié)構(gòu)優(yōu)化，提升了升降平臺的可維修性；通過有限元優(yōu)化設(shè)計，提升了升降平臺的性能重量比。從而使深井式立體智能車庫具有很高的可靠性、經(jīng)濟性和可維修性。論文主要包含以下具體研究內(nèi)容： （1）對自行式升降平臺進行了力學(xué)分析，利用有限元軟件ANSYS分析平臺桁架的受力變形，并對其焊接結(jié)構(gòu)進行了優(yōu)化設(shè)計，提高平臺桁架的剛度，減小桁架變形對悶車現(xiàn)象的影響。 （2）設(shè)計齒距控制規(guī)對齒輪齒條的裝配精度進行控制，并采用磁性直角水平儀控制齒條的安裝精度，保證齒輪齒條嚙合的準(zhǔn)確性、平穩(wěn)性和載荷分布均勻性；此外，為避免因齒條松動造成的振動、噪聲和安全事故，采用移植創(chuàng)造和組合創(chuàng)新的方法，創(chuàng)新設(shè)計了齒條安裝的防松方案。從而有效控制了升降系統(tǒng)的制造和安裝精度。 （3）進行了升降平臺偏載條件下的力學(xué)分析，指出桁架變形量對傳動裝置的影響不足以引發(fā)負(fù)載運行過程中的“悶車”現(xiàn)象，剖析出液壓馬達在偏載條件下的啟動阻力過大、輸出功率大大超出其出廠設(shè)置值是導(dǎo)致“悶車”現(xiàn)象的根本原因。 （4）系統(tǒng)分析現(xiàn)行同步裝置適用性的基礎(chǔ)上，采用移植創(chuàng)造和組合創(chuàng)新的方法，設(shè)計制造出齒輪齒條消隙式剛性同步機構(gòu)；基于維修性，對同步機構(gòu)進行了結(jié)構(gòu)優(yōu)化，提升了升降平臺的可維修性；最后，進行了同步機構(gòu)的輕量化研究，提高了升降平臺的性能重量比。 試驗運行表明，采用消隙式剛性同步機構(gòu)的深井式立體智能車庫取得了良好的同步效果，有效解決了“悶車”問題，并為同類升降平臺同步問題的解決提供了理論支撐和技術(shù)解決方案。
[Abstract]:With the increasing number of urban cars, the parking difficulty has become a high concern in today's society and the problem that the government needs to solve. The development of the city makes the land precious. It is a dilemma to plan the parking area on the ground to solve the problem of parking, and the development of underground parking space is undoubtedly the solution to this problem. An effective way to solve the problem.
Deep well stereoscopic intelligent garage is a kind of integrated stereo parking equipment built in the underground, its advanced structure design and layout can make up for the existing other forms of the existing three-dimensional garage with large area, high energy consumption, large noise, long time to access the car, and not easy to combine to form a garage group, and effectively solve the stop. In the development and trial operation of the deep well type three-dimensional intelligent garage, it is found that the self-propelled lift platform is easy to produce "stuffy car" phenomenon, which will seriously affect the reliable operation and application of this kind of garage.
In view of the "stuffy car" phenomenon of deep well stereoscopic intelligent garage, this paper takes the PSC8CK-4ZT type garage as the blueprint, optimizes the welding structure of the lifting platform truss, effectively controls the manufacturing and installation accuracy of the lifting system, and analyzes the excessive load of the hydraulic motor starting with partial load, and the output power is greatly beyond the set value of its factory. It is the main reason for the phenomenon of the stuffing, comparing and analyzing the current synchronization scheme. By using the method of transplant creation and combination innovation, the gear rack clearance type rigid synchronous machine with simple structure, fast synchronous response speed, good stability and high reliability is developed. The structure optimization is used to further improve the lifting platform. It can improve the performance and weight ratio of the lifting platform by the finite element optimization design, so that the deep well stereoscopic intelligent garage has high reliability, economy and maintainability. The main contents of this paper are as follows:
(1) the mechanical analysis of the self-propelled lifting platform was carried out. The finite element software ANSYS was used to analyze the stress and deformation of the platform truss, and the welding structure was optimized. The stiffness of the truss was improved and the effect of truss deformation on the phenomenon of the car was reduced.
(2) the precision of gear and rack assembly is controlled by the design of tooth distance control gauge, and the magnetic right angle level instrument is used to control the installation precision of the rack, to ensure the accuracy of the gear rack meshing, the smoothness and the uniformity of load distribution. In addition, to avoid the vibration, noise and safety accidents caused by the loosening of the rack, the creation and combination of transplanting are adopted. The new method innovating the design of rack loosening prevention, thus effectively controlling the manufacturing and installation accuracy of the lifting system.
(3) the mechanical analysis of the lifting platform under the loading condition is carried out. It is pointed out that the influence of the truss deformation amount to the transmission device is not enough to trigger the "stuffy car" phenomenon during the load operation. It is found out that the starting resistance of the hydraulic motor under the partial load is too large and the output power is greatly beyond its factory setting value, which is the root of the "stuffy car" phenomenon. Reason.
(4) on the basis of analyzing the applicability of the current synchronizer system, the gear and rack clearance rigid synchronization mechanism is designed and manufactured with the method of transplant creation and combination innovation. Based on the maintainability, the structure optimization of the synchronization mechanism is carried out and the repairability of the lifting platform is improved. Finally, the lightweight research of the synchronization mechanism is carried out. The performance and weight ratio of the lifting platform is higher.
The experimental operation shows that the deep well stereoscopic intelligent garage with the stilling rigid synchronous mechanism has achieved good synchronization effect, effectively solves the problem of "stuffy car", and provides theoretical support and technical solution for solving the synchronization problem of similar lifting platform.
