Description
本發明是一種雙滾動螺桿式升降機構。
The invention is a double rolling screw type lifting mechanism.
隨著社會繁榮、大樓林立，升降移動機構（電梯、貨梯等）已經是現今生活中不可或缺的生活必需工具，而最常見的傳統升降移動機構驅動方式是以鋼索驅動，但鋼索驅動的移動台需要經常性的保養，否則就會導致鋼索斷裂而產生人員傷亡的狀況發生。
因此，還有另外一種螺桿驅動式的升降機１０，如圖七所示為中華民國專利第５４３６４９號「螺桿式升降機」之專利案，該專利主要要解決的問題是，當升降機的升降高度較高時，相對螺桿也較長，故造成螺桿製造不易，且安裝長度較長的螺桿至坑道更是件非常困難的事，就必須由吊車將螺桿從坑道的頂端置入坑道中（但假設遇到坑道頂端無坑孔的就無法安裝了），故大大提高了整體的成本，故該升降機（１０）是藉由複數個螺桿驅動（其將整體的升降高度分散至各螺桿，使螺桿的長度縮短），且該升降機（１０）是串聯了一固定螺桿組（１１）、一中繼螺桿組（１２）以及一車廂螺桿組（１３），且該各螺桿組（１１、１２、１３）分別電性連接一動力源（１１１、１２１、１３１），該些動力源（１１１、１２１、１３１）驅動該些螺桿組（１１、１２、１３），使該車廂螺桿組（１３）帶動一車廂（１４）進行線性運動，藉由螺桿的驅動方式降低該升降機發生事故的機率，且藉由串聯該各螺桿組的組配方式縮短所使用螺桿的長度，降低螺桿的加工困難度，然而，該移動台設備為了達成上述目的，需藉由該各螺桿組進行串聯，且該各螺桿組還需分別連接一動力源，使得該移動台設的結構與組配的複雜度都大為增加，更增加了裝配該移動台設備的難度，且光是動力源及複雜機構的成本就占總成本的百分之四十以上，有鑑於此，本發明人潛心研究並更深入構思，歷經多次研發試作後，終於發明出一種雙螺桿式升降移動機構。
With the prosperity of the society and the buildings, the moving and moving mechanisms (elevators, freight elevators, etc.) have become an indispensable tool for life in today's life. The most common traditional lifting and moving mechanism is driven by steel cables, but the cable-driven movement The station needs regular maintenance, otherwise it will cause the cable to break and cause casualties.
Therefore, there is another screw-driven elevator 10, as shown in Fig. 7, which is a patent of the "screw elevator" of the Republic of China Patent No. 543649. The main problem to be solved by the patent is that the lift height of the elevator is relatively high. When the screw is also relatively long, it is not easy to manufacture the screw, and it is very difficult to install the screw to the tunnel with a long length. It is necessary to put the screw into the tunnel from the top of the tunnel by the crane (but it is assumed to be encountered). The top of the tunnel can be installed without a hole, so the overall cost is greatly increased. Therefore, the elevator (10) is driven by a plurality of screws (which disperse the overall lifting height to each screw to shorten the length of the screw). And the elevator (10) is a series of fixed screw sets (11), a relay screw set (12) and a car screw set (13), and the screw sets (11, 12, 13) are respectively electrically Connected to a power source (111, 121, 131), the power sources (111, 121, 131) drive the screw sets 11, 12, 13), the carriage screw group (13) drives a carriage (14) to perform linear motion, and the speed of the elevator is reduced by the driving method of the screw, and the assembly of the screw groups is connected in series. The method shortens the length of the screw used and reduces the difficulty of processing the screw. However, in order to achieve the above object, the mobile station device needs to be connected in series by the screw groups, and the screw groups also need to be respectively connected with a power source, so that The complexity of the structure and assembly of the mobile station is greatly increased, and the difficulty of assembling the mobile station equipment is increased, and the cost of the power source and the complex mechanism accounts for more than 40% of the total cost. In view of this, the inventors have devoted themselves to research and intensively conceived, and after many trials and developments, finally developed a twin-screw lifting and moving mechanism.
