Description
本發明係應用於卡車裝備之技術領域，尤指一種能有效及穩定啟閉卡車車斗遮罩的卡車車斗遮罩啟閉之昇降緃擒機構。 The invention relates to the technical field of truck equipment, in particular to a lifting and lowering mechanism for effectively opening and closing a truck body cover that can open and close a truck body cover.
按，為增進卡車行進的安全及貨物的定位效果，例如砂石或貨物等，需在卡車行駛間於車斗上罩設有一層的遮罩，以避免砂石或貨物等飛出，但一般習知卡車車斗遮罩啟閉大都經由一樞設於卡車周緣之ㄇ字形擺臂旋轉，且配合一昇降捲收機構及一昇降機構的連動，以連動遮罩之開啟或罩設，而其中昇降機構主要藉由彈簧直接拉持臂桿，且配合昇降捲收機構，以旋轉拉動臂桿，但習知卡車車斗遮罩啟閉之昇降機構，受限於昇降機構的彈簧設計，會在遮罩在遮蓋車斗過程中，即擺臂兩側臂桿超過垂直位置，即利用擺臂的重力，使擺臂自然朝車斗後方旋轉，以完成遮罩的動作。 In order to improve the safety of the truck and the positioning effect of the cargo, such as sand or cargo, it is necessary to cover the bucket with a layer of cover on the truck to avoid flying sand or cargo, but generally Most of the conventional truck body cover opening and closing is rotated by a 摆-shaped swing arm pivoted on the periphery of the truck, and is coupled with a lifting and lowering mechanism and a lifting mechanism to open or cover the cover. The lifting mechanism mainly pulls the arm by a spring and cooperates with the lifting and lowering mechanism to rotate and pull the arm. However, the lifting mechanism of the conventional truck body cover opening and closing is limited by the spring design of the lifting mechanism. The mask covers the body during the process of covering the body, that is, the arms on both sides of the swing arm exceed the vertical position, that is, the gravity of the swing arm is used to rotate the swing arm naturally toward the rear of the vehicle to complete the action of the mask.
經由上述的昇降機構受限於彈簧設計，即彈簧長度不足而伸張太長則容易造成彈性疲乏，而彈簧太短則容易造成拉伸距離不足與彈性拉力不足的問題，因此，雖然可方便將遮罩開啟或遮蔽於車斗，但，由於卡車在進行遮罩遮蔽作業過程中，於車斗後方有強風吹過時，尤其一般卡車作業環境，通常屬於較為空曠的區域，例如河床或空地等，風力較強， 此時由於擺臂處於後段遮蔽過程，當擺臂兩側臂桿呈超過垂直位置，其拉伸彈簧已呈不受拉力，每一圈都緊靠在一起的原始狀態，而在彈簧沒有拉力情況下，擺臂利用本身的重力自朝下垂，遮罩的受風面積大，容易導致遮罩產生揚帆狀況而無法穩定持續往下遮蔽車斗，此時昇降捲收機構仍持續動作，造成昇降捲收機構的複數條鋼索持續放線，導致容易多條鋼索呈鬆弛狀態，不僅使昇降捲收機構鉸盤之鋼索捲收紊亂，更容易使擺臂受力不均，造成傾斜及跳動等問題，形成昇降捲收機構損耗及遮罩無法有效及穩定遮蔽車斗的問題發生。 The above-mentioned lifting mechanism is limited by the spring design, that is, if the length of the spring is insufficient and the tension is too long, the elastic fatigue is easily caused, and if the spring is too short, the problem of insufficient stretching distance and insufficient elastic pulling force is easily caused, so that it is convenient to cover. The cover is opened or shielded from the body of the vehicle. However, when the truck is subjected to strong wind blowing behind the vehicle during the masking operation, especially in the general working environment of the truck, it is usually a relatively empty area, such as a river bed or an open space. Strong, At this time, since the swing arm is in the rear section shielding process, when the arms on both sides of the swing arm are more than the vertical position, the tension springs are not pulled, and each turn is close to the original state, and there is no tension in the spring. Under the sway, the swing arm hangs down by its own gravity, and the wind receiving area of the mask is large, which easily causes the hood to generate a sail condition and cannot stably and continuously shield the hopper. At this time, the lifting and retracting mechanism continues to move, resulting in lifting and lowering. The plurality of steel cables of the receiving mechanism are continuously released, which makes it easy for a plurality of steel cables to be in a relaxed state, which not only makes the steel cable of the lifting and retracting mechanism reaming disorder, but also makes the swing arm unevenly distributed, causing problems such as tilting and jumping. The problem of the lifting and lowering mechanism loss and the mask cannot effectively and stably cover the body.
本發明者有鑑於前述習用卡車車斗遮罩啟閉之昇降機構於實際使用上，仍有遮罩無法有效及穩定遮蔽車斗及導致昇降捲收機構使用壽命不佳的問題發生，進而開發出本發明卡車車斗遮罩啟閉之昇降緃擒機構。 The present inventors have developed in view of the fact that the lifting mechanism of the conventional truck body cover opening and closing is actually used, and the problem that the mask cannot be effectively and stably shielded the vehicle body and the service life of the lifting and lowering mechanism is not good is developed.

當捲收遮罩13時使用時，如第1圖及第4圖所示，此時初始狀態為遮罩13已完全遮罩住車斗12，且昇降捲收機構20之動力源21啟動鉸盤組22作旋轉，使複數鋼索23同步捲收，而拉動擺臂14兩封閉端141之間，連動臂桿140以樞軸15為中心朝鉸盤組22方向旋轉，且在擺臂14旋轉的同時，會依序連動遮網揚昇裝置30，即經由連動件143拉伸第一彈性元件33，且當臂桿140持續旋轉的同時，亦會連動遮網下壓蓋合裝置40，帶動擺動件45旋轉，以拉動第二撓性體連接物44朝異於第二彈性元件43方向捲收，而使第二彈性元件43被彈性拉伸，以縮短第二彈性元件43與樞軸15間的距離，以至遮罩13完全捲收完成，此時，第一彈性元件33及第二彈性元件43均呈拉伸狀態，另外，本實施例之第一彈性元件33及第二彈性元件43能依所需要的彈力，分別旋轉第一微調件32及第二微調件42，以使第一微調件32及第二微調件42能分別呈水平方向移動，藉以調整第一彈性元件33及第二彈性元件43的彈力。 When the mask 13 is taken up, as shown in FIGS. 1 and 4, the initial state is that the mask 13 has completely covered the body 12, and the power source 21 of the lifting and lowering mechanism 20 starts the hinge. The disk group 22 is rotated to synchronously retract the plurality of cables 23, and between the two closed ends 141 of the swing arm 14, the interlocking arm 140 rotates in the direction of the hinge group 22 about the pivot 15 and rotates on the swing arm 14. At the same time, the net lifting device 30 is connected in sequence, that is, the first elastic member 33 is stretched via the linking member 143, and when the arm 140 continues to rotate, the cover lower pressing device 40 is also driven. The swinging member 45 rotates to pull the second flexible body connector 44 in a direction different from the second elastic member 43 to elastically stretch the second elastic member 43 to shorten the second elastic member 43 and the pivot 15 The distance between the first elastic member 33 and the second elastic member 43 is in a stretched state. In addition, the first elastic member 33 and the second elastic member 43 of the present embodiment are in a stretched state. The first fine adjustment member 32 and the second fine adjustment member 42 can be respectively rotated according to the required elastic force to make the first fine adjustment 32 and the second trim member 42 can be respectively disposed in the horizontal direction, so as to adjust the elastic force of the first elastic member 33 and the second elastic member 43.
當需將遮罩13遮蔽於車斗12時，請參閱第1圖及第5圖所示，此時，鉸盤組22會將複數鋼索23逐漸旋轉拉出，而受到遮網揚昇裝置30之第一彈性元件33之拉伸彈力影響，擺臂14一方面受到複數鋼索23拉力影響，另一方面受到第一彈性元件33之拉伸彈力作用，會使擺臂14朝卡車10後方旋轉，再請參閱第6圖所示，當第一彈性元件33回覆至原未拉伸狀態時，此時遮網揚昇裝置30則無使擺臂14下壓的力量，而此時第二彈性元件 43即能經由經由拉伸之回復彈力，以拉動擺動件45旋轉，而使第二撓性體連接物44朝第二彈性元件43方向移動，以供第二彈性元件43受到複數鋼索23的拉力，以及配合擺臂14的重力，緩慢回復至未拉伸狀態，而將擺臂14穩定的旋轉，同時提供遮罩13遮蔽車斗12的定位效果。 When the mask 13 needs to be shielded from the body 12, please refer to FIG. 1 and FIG. 5. At this time, the hinge group 22 gradually rotates and pulls out the plurality of cables 23, and receives the net lifting device 30. The tension arm of the first elastic member 33 affects the swing arm 14 on the one hand by the tensile force of the plurality of cables 23, and on the other hand by the tensile elastic force of the first elastic member 33, causing the swing arm 14 to rotate toward the rear of the truck 10. Referring to FIG. 6 again, when the first elastic member 33 is returned to the original unstretched state, the shutter lifting device 30 has no force for pressing the swing arm 14 at this time, and the second elastic member is at this time. 43 is capable of moving the second flexible body connector 44 toward the second elastic member 43 by pulling the swinging member 45 to rotate by the elastic force of the tension by stretching, so that the second elastic member 43 is subjected to the pulling force of the plurality of cables 23 And the gravity of the swing arm 14 is slowly returned to the unstretched state, and the swing arm 14 is stably rotated while providing the shielding effect of the shield 13 to shield the body 12.
此時，若遮罩13於遮蔽車斗12的過程中，遇到有強風由車斗12後方吹來時，本實施例不僅能靠擺臂14本身的重力，更包含有第二彈性元件43的彈性拉力，能穩定及安全的將遮罩13遮蔽於車斗12。 At this time, if the strong air is blown from the rear of the vehicle body 12 during the process of covering the body 12, the present embodiment can not only rely on the gravity of the swing arm 14 itself, but also includes the second elastic member 43. The elastic pulling force can shield the cover 13 to the body 12 stably and safely.
