搅拌车工具的一种新型制作简述过程
搅拌车是用于运送建筑用的混凝土的专用车。在运输过程中，搅拌车的搅拌筒需要始终保持转动状态，以保证所运载的混凝土不会凝固。这里所制作的目的在于现有技术的搅拌车中回转轴承为一体结构的金属定制构件，损坏后需要整体更换，搅拌车生产及维修成本高的技术问题。
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.
为上述技术问题，新型提供一种搅拌车，包括车架、安装在所述车架上的搅拌筒以及固定在该车架上的进出料装置，所述搅拌筒可相对所述车架转动，该搅拌筒的后端设有料口，所述进出料装置与所述料口对应；所述搅拌车还包括回转连接单元，所述回转连接单元包括固定圈、转动圈、过渡组件以及挡板；
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;
固定圈与所述进出料装置可拆卸连接；所述固定圈侧壁开设有凹槽，所述凹槽沿该固定圈的轴向延伸；转动圈可拆卸地固定在所述料口处，并可随所述搅拌筒转动；所述转动圈容置在所述凹槽中，该转动圈的外环面与所述凹槽的内壁之间形成周向的容置腔，所述容置腔在该固定圈侧壁处具有一开口；
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;
过渡组件包括固定支架和多个辊动块；所述固定支架呈环状，该固定支架的周向间隔开设有多个安装槽，所述辊动块卡接在该安装槽中；所述过渡组件设置在该容置腔中，该辊动块的表面与所述固定圈和所述转动圈相接触，以使所述转动圈能够相对所述固定圈转动；挡板可拆卸地连接在所述固定圈的侧壁上；所述挡板挡止在所述容置腔的开口处，以在所述固定圈的轴向上限位该辊动块。
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.
所述转动圈与所述固定圈之间还形成有气压室和密封腔，所述气压室和所述密封腔均位于所述容置腔靠近所述进出料装置的一侧，所述气压室和所述密封腔均环绕所述料口的轴线；所述回转连接单元还包括密封体，所述密封体呈环状，该密封体密封地收容于所述密封腔中；所述密封体的一端端面环设有密封槽，所述密封槽的内侧周壁在往该密封槽的开口方向上朝向所述密封体的倾斜。
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.
自上料搅拌车厂家认为本新型的搅拌车中，回转连接单元的固定圈、转动圈、辊动块以及挡板呈分体式设置。当固定圈、转动圈、辊动块及挡板中的一种或几种损坏时，无需整体更换回转连接单元，只需拆卸损坏部件并对应更换新部件即可，从而避免部件的局部问题造成回转连接单元整体更换的材料浪费的情况，有效地降低了维修成本。
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.
同时，固定圈和转动圈分别与进出料装置和搅拌筒可拆卸连接，挡板可拆卸地连接在固定圈上。当回转连接单元中的部件需要更换时，固定圈、转动圈以及挡板均可快速拆卸，以缩短回转连接单元的维修时间，提高搅拌车整体的维护效率。
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.
