攪拌車工具的一種新型制作簡述過程
攪拌車是用于運送建筑用的混凝土的專用車。在運輸過程中，攪拌車的攪拌筒需要始終保持轉動狀態(tài)，以保證所運載的混凝土不會凝固。這里所制作的目的在于現(xiàn)有技術的攪拌車中回轉軸承為一體結構的金屬定制構件，損壞后需要整體更換，攪拌車生產及維修成本高的技術問題。
Mixer truck is a special vehicle for transporting concrete for construction. During transportation, the mixing drum of the mixer truck needs to always keep rotating to ensure that the transported concrete will not solidify. The purpose of the production here is to solve the technical problem that the metal customized components with the rotary bearing as an integral structure in the mixer truck of the prior art need to be replaced as a whole after damage, and the production and maintenance cost of the mixer truck is high.
為上述技術問題，新型提供一種攪拌車，包括車架、安裝在所述車架上的攪拌筒以及固定在該車架上的進出料裝置，所述攪拌筒可相對所述車架轉動，該攪拌筒的后端設有料口，所述進出料裝置與所述料口對應；所述攪拌車還包括回轉連接單元，所述回轉連接單元包括固定圈、轉動圈、過渡組件以及擋板；
In order to solve the above technical problems, a new type of mixer truck is provided, which includes a frame, a mixing drum installed on the frame and a feeding and discharging device fixed on the frame. The mixing drum can rotate relative to the frame, and the rear end of the mixing drum is provided with a material inlet, which corresponds to the material inlet; The mixer truck also includes a rotary connection unit, which includes a fixed ring, a rotating ring, a transition component and a baffle;
固定圈與所述進出料裝置可拆卸連接；所述固定圈側壁開設有凹槽，所述凹槽沿該固定圈的軸向延伸；轉動圈可拆卸地固定在所述料口處，并可隨所述攪拌筒轉動；所述轉動圈容置在所述凹槽中，該轉動圈的外環(huán)面與所述凹槽的內壁之間形成周向的容置腔，所述容置腔在該固定圈側壁處具有一開口；
The fixing ring is detachably connected with the feeding and discharging device; The side wall of the fixed ring is provided with a groove, and the groove extends along the axial direction of the fixed ring; The rotating ring is detachably fixed at the material port and can rotate with the mixing drum; The rotating ring is contained in the groove, a circumferential containing cavity is formed between the outer ring surface of the rotating ring and the inner wall of the groove, and the containing cavity has an opening at the side wall of the fixed ring;
過渡組件包括固定支架和多個輥動塊；所述固定支架呈環(huán)狀，該固定支架的周向間隔開設有多個安裝槽，所述輥動塊卡接在該安裝槽中；所述過渡組件設置在該容置腔中，該輥動塊的表面與所述固定圈和所述轉動圈相接觸，以使所述轉動圈能夠相對所述固定圈轉動；擋板可拆卸地連接在所述固定圈的側壁上；所述擋板擋止在所述容置腔的開口處，以在所述固定圈的軸向上限位該輥動塊。
The transition component comprises a fixed support and a plurality of roller moving blocks; The fixed support is annular, a plurality of installation grooves are arranged at circumferential intervals of the fixed support, and the roller block is clamped in the installation groove; The transition component is arranged in the holding cavity, and the surface of the roller block is in contact with the fixed ring and the rotating ring, so that the rotating ring can rotate relative to the fixed ring; The baffle is detachably connected to the side wall of the fixing ring; The baffle is blocked at the opening of the holding cavity to position the roller block at the axial upper limit of the fixed ring.
所述轉動圈與所述固定圈之間還形成有氣壓室和密封腔，所述氣壓室和所述密封腔均位于所述容置腔靠近所述進出料裝置的一側，所述氣壓室和所述密封腔均環(huán)繞所述料口的軸線；所述回轉連接單元還包括密封體，所述密封體呈環(huán)狀，該密封體密封地收容于所述密封腔中；所述密封體的一端端面環(huán)設有密封槽，所述密封槽的內側周壁在往該密封槽的開口方向上朝向所述密封體的傾斜。
An air pressure chamber and a sealing cavity are also formed between the rotating ring and the fixed ring. Both the air pressure chamber and the sealing cavity are located on the side of the holding cavity close to the feeding and discharging device, and both the air pressure chamber and the sealing cavity surround the axis of the feeding and discharging port; The rotary connection unit also includes a sealing body, which is in a ring shape and is hermetically received in the sealing cavity; One end face ring of the sealing body is provided with a sealing groove, and the inner peripheral wall of the sealing groove is inclined towards the center of the sealing body in the direction of the opening of the sealing groove.
自上料攪拌車廠家認為本新型的攪拌車中，回轉連接單元的固定圈、轉動圈、輥動塊以及擋板呈分體式設置。當固定圈、轉動圈、輥動塊及擋板中的一種或幾種損壞時，無需整體更換回轉連接單元，只需拆卸損壞部件并對應更換新部件即可，從而避免部件的局部問題造成回轉連接單元整體更換的材料浪費的情況，有效地降低了維修成本。
The manufacturer of the charging mixer believes that in this new type of mixer, the fixed ring, rotating ring, roller block and baffle of the rotary connection unit are arranged in a split manner. When one or more of the fixed ring, rotating ring, roller block and baffle are damaged, there is no need to replace the rotary connection unit as a whole, just dismantle the damaged parts and replace them with new parts accordingly, so as to avoid the material waste caused by the local problems of the parts, and effectively reduce the maintenance cost.
同時，固定圈和轉動圈分別與進出料裝置和攪拌筒可拆卸連接，擋板可拆卸地連接在固定圈上。當回轉連接單元中的部件需要更換時，固定圈、轉動圈以及擋板均可快速拆卸，以縮短回轉連接單元的維修時間，提高攪拌車整體的維護效率。
At the same time, the fixed ring and the rotating ring are detachably connected with the feeding and discharging device and the mixing drum respectively, and the baffle is detachably connected to the fixed ring. When the components in the rotary connection unit need to be replaced, the fixed ring, rotating ring and baffle can be removed quickly, so as to shorten the maintenance time of the rotary connection unit and improve the overall maintenance efficiency of the mixer.
