Description
本創作係關於一種無限揚程絞盤吊車，尤指一種在動力源與減速機構間裝設有一傳動及棘輪剎車機構，確保可以準確剎車停機之無限揚程絞盤吊車。This creation is about an infinite lift winch crane, especially an infinite lift winch crane that is equipped with a transmission and ratchet brake mechanism between the power source and the speed reduction mechanism to ensure accurate braking and shutdown.
按，"吊車"是一種裝設於高處，藉由動力收、放鋼索，以供吊起或放下重物用之吊重用動力機具，經常亦被稱為"動力絞車"，或被稱為"吊重捲揚機。吊車有很多種構造型態，用於負載較重範圍者會由很多複雜構造組成，用於負載較輕範圍者則構造相對較為簡便。Press, "crane" is a kind of hoisting power equipment that is installed at a high place and is used for lifting and lowering steel cables for lifting or lowering heavy objects. It is often called "power winch" or is called "Hoisting hoist. There are many types of constructions for cranes. For heavy load ranges, it will consist of many complicated structures. For those with light load range, the construction is relatively simple.
一種負載範圍更輕之吊車是為"無限揚程絞盤吊車"，習知無限揚程絞盤吊車具有一動力源(例如：馬達)，該動力源之出力軸帶動一減速機構作用，經過減速機構後之動力則帶動一絞盤機構轉動，該絞盤機構內可嵌置入一繩索達成絞接，該絞盤機構上方並設置有一懸掛用之掛勾，使用時，啟動該動力源，經過該減速機構減速後，帶動該絞盤機構轉動，因此而可帶(推)動該繩索行走，一般係推動該繩索向上揚程移動，如此可藉由該繩索將重物往上拉動，例如：進行工程時可藉由該無限揚程絞盤吊車的繩索將工具送到高樓層；或者，該繩索可於另一高處經過一滑輪(pulley)後往下行走，因此可帶動重物往下送。A crane with a lighter load range is an "infinite lift winch crane". The conventional infinite lift winch crane has a power source (for example, a motor), and the output shaft of the power source drives a speed reduction mechanism, and the power after the speed reduction mechanism Then driving a winch mechanism to rotate, the winch mechanism can be embedded with a rope to achieve the splicing, and a hanging hook is arranged above the winch mechanism. When in use, the power source is activated, and after being decelerated by the speed reducing mechanism, the driving is started. The winch mechanism rotates, so that the rope can be moved (pushing), generally pushing the rope to move up, so that the weight can be pulled up by the rope, for example, the infinite head can be used for engineering The rope of the winch crane transports the tool to the upper floor; or the rope can travel down the pulley at another high point, so that the heavy object can be carried down.
習知無限揚程絞盤吊車在使用上，係經由導通(CLOSE)該動力源之電源而開啟作用，然後經由斷開(OPEN)該動力源之電源而停止作用，嚴格講，就是習知無限揚程絞盤吊車之構造組成內並無剎車機構，而是利用停止該動力源(馬達)之電源來達成停機作用。然因動力源(馬達)在停止電源時尚有轉動之餘勢，並非立即停止出力，因此利用關閉動力源(馬達)之電源來控制停機，實際上是無法準確停止，而會存在行程差距，且使用日久後，行程差距會加劇，倘遇負荷過大時，恐反而帶動動力源(馬達)回轉，因而造成機件之毀損及使用安全性之顧慮。The conventional infinite lift winch crane is used to turn on the power source of the power source by CLOSE, and then stops by OPEN the power source of the power source. Strictly speaking, it is a conventional infinite lift winch. There is no brake mechanism in the construction of the crane, but the power supply to stop the power source (motor) is used to achieve the shutdown effect. However, because the power source (motor) has a turning point in stopping the power supply fashion, it does not immediately stop the output. Therefore, by using the power source of the power source (motor) to control the shutdown, it is actually impossible to stop accurately, and there is a travel gap, and After a long period of use, the travel gap will increase. If the load is too large, it will cause the power source (motor) to rotate, which will cause damage to the machine and safety of use.

The through hole 271 is fixed to the side wall of the power source 10 so that the output shaft 11 of the power source 10 passes through the through hole 271 and then the central shaft hole of the driving gear 21 The 211 is inserted and engaged, and the left casing 27 faces the side casing of the transmission and the ratchet brake mechanism 20, and a plurality of accommodating grooves are arranged in advance, and the bearing 111, the bearing 2211 and one of the shafts 2341 are accommodated therein. Positioning is achieved; the right housing 28 is mainly provided with a through hole 281 in the center thereof. When installed, the right housing 28 is fixed to the side wall of the winch mechanism 30, so that the long rod-shaped shaft 261 of the driven gear 26 is worn. After the through hole 281 and the through hole 31 passing through the center of the winch mechanism 30, the speed reduction mechanism 40 is entered. For the force connection, the right housing 28 faces the side of the transmission and the ratchet brake mechanism 20, and a plurality of receiving slots are provided in advance for the bearing 2212, the bearing 2611, the other shaft 2341 and the elastic member 2343. When the left housing 27 and the right housing 28 are connected in parallel, the middle portion is further locked by a lining 29 to make the joint state achieve sealing and waterproofing.
如圖10所示，該絞盤機構30上方接設有一供懸掛用之掛勾32，供將整體懸置於高處，該電控機構50組裝於該動力源10上方，該電控機構50外側具有一開關鈕51、一顯示燈52及一插接座53，該開關鈕51控制該動力源10是否通電，通電時該顯示燈52會亮起，該插接座53可供一手持有線控制器54插接連線使用。As shown in FIG. 10, a hook 32 for hanging is attached to the upper portion of the winch mechanism 30 for hanging the whole portion. The electronic control unit 50 is assembled above the power source 10, and the outside of the electronic control unit 50 The switch button 51 controls whether the power source 10 is energized. When the power is turned on, the display lamp 52 lights up, and the plug socket 53 can be controlled by a hand-held cable. The device 54 is plugged in and used.
使用時，當啟動該動力源10正向轉動時，該動力源10的出力軸11即帶動該主動齒輪21同步轉動，並經由嚙接帶動該連軸齒輪22反向轉動，因此該連軸齒輪22的外螺接紋222經由與該內螺接紋241間之螺緊，可將該中間齒輪24拉近抓緊，使得該連軸齒輪22、該單向棘輪23及該中間齒輪24三者會共同夾設住成為一體般，呈現同步轉動之作用狀態，此時該單向棘輪23之轉動方向因係不受該棘輪卡掣塊234所阻擋，所以該連軸齒輪22、該單向棘輪23及該中間齒輪24三者呈現一體順利轉動之作用狀態，進而該中間齒輪24即經由嚙接帶動該被動齒輪26正向轉動(即與該出力軸11及該主動齒輪21同向轉動)，再由該被動齒輪26的長桿狀軸心261將動力導入該減速機構40內，達成減速作用，再導入該絞盤機構30內使做出反向轉動動作，以帶動該繩索60向上方揚程移動，進行經由該繩索60帶動重物上升之預期動作。由此可知，該絞盤吊車1在用於帶動該繩索60做出向上方揚程移動之動作時，該傳動及棘輪剎車機構20係發揮"傳動"作用，可將該動力源10輸出之動力傳輸到該減速機構30。In use, when the power source 10 is started to rotate in the forward direction, the output shaft 11 of the power source 10 drives the driving gear 21 to rotate synchronously, and the coupling gear 22 is reversely rotated via the meshing, so the coupling gear The outer screw 222 of the second screw 222 is tightened by the inner screw 241, and the intermediate gear 24 can be tightened, so that the coupling gear 22, the one-way ratchet 23 and the intermediate gear 24 The common clamping is integrated, and the synchronous rotation state is exhibited. At this time, the rotation direction of the one-way ratchet 23 is not blocked by the ratchet latching block 234, so the coupling gear 22 and the one-way ratchet 23 And the intermediate gear 24 is in a state of smooth rotation, and the intermediate gear 24 drives the driven gear 26 to rotate in the forward direction (ie, rotates in the same direction as the output shaft 11 and the driving gear 21). The power is introduced into the speed reduction mechanism 40 by the long rod-shaped shaft center 261 of the driven gear 26 to achieve a deceleration action, and is introduced into the winch mechanism 30 to perform a reverse rotation operation to drive the rope 60 to move upward. Carrying weight through the rope 60 The action is expected to rise. It can be seen that when the winch crane 1 is used to drive the rope 60 to move upwardly, the transmission and the ratchet brake mechanism 20 play a "transmission" function, and the power output from the power source 10 can be transmitted to The speed reduction mechanism 30.
在使用狀態進行中，操作者只要一按下該手持有線控制器54上之停止鍵時，即刻斷開該動力源10之電力(倘遇停電時也是同樣情況)，所以該出力軸11瞬即停止輸出動力，使得該主動齒輪21及該連軸齒輪22停止轉動，相對之下受重物重力拉動所產生之反向扭力會通過該絞盤機構30、該減速機構40及該被動齒輪26之連動作用後，驅使該中間齒輪24、該單向棘輪23及該連軸齒輪22三者所呈現之一體朝反向轉動，惟因該單向棘輪23一反向即受到該棘輪卡掣塊234所阻擋，加上該中間齒輪24表面上所插接之卡擋短桿243受到該卡擋塊25之卡擋凹槽252所阻擋，致使該中間齒輪24、該單向棘輪23及該連軸齒輪22三者所呈現之一體只得即刻停止動作，如此就能完成在動力源與減速機構間裝設有該傳動及棘輪剎車機構20，解以確保可以準確剎車停機之作用功效。由此可知，該絞盤吊車1在斷電停機時，該傳動及棘輪剎車機構20係發揮準確之"剎車"作用。In the state of use, the operator simply turns off the power of the power source 10 as soon as the stop button on the handheld cable controller 54 is pressed (the same is true in the event of a power outage), so the output shaft 11 is instantaneously The output power is stopped, so that the driving gear 21 and the coupling gear 22 stop rotating, and the reverse torque generated by the gravity pulling of the weight is relatively transmitted through the winch mechanism 30, the speed reducing mechanism 40 and the driven gear 26 After the action, the one of the intermediate gear 24, the one-way ratchet 23 and the coupling gear 22 is driven to rotate in the opposite direction, but the ratchet latching block 234 is received by the one-way ratchet 23 in the reverse direction. Blocking, and the latching short rod 243 inserted on the surface of the intermediate gear 24 is blocked by the latching recess 252 of the latching block 25, so that the intermediate gear 24, the one-way ratchet 23 and the coupling gear 22 One of the three presents only has to stop the action immediately, so that the transmission and ratchet brake mechanism 20 can be installed between the power source and the speed reduction mechanism to solve the effect of ensuring accurate braking and stopping. It can be seen that the drive and the ratchet brake mechanism 20 play an accurate "brake" function when the winch crane 1 is powered off.
