If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.
Referring to fig. 1 to 4, in one embodiment of the present invention, a canister lid control mechanism of a well-type vacuum canister is provided, the well-type vacuum canister including a canister body 110 having an opening 111 at a top end thereof and a lid body 120 capable of opening and closing the opening 111, the canister lid control mechanism including a translation mechanism 200 and a turnover mechanism 300; the translation mechanism 200 is connected with the cover 120; when the translation mechanism 200 drives the cover 120 to move horizontally to a position where the middle axis of the cover 120 is tangent to the edge of the opening 111, the turnover mechanism 300 drives the cover 120 to turn over around the middle axis of the cover 120.
In this embodiment, the cover 120 is horizontally moved by the translation mechanism 200 to a position where the middle axis portion of the cover 120 is tangent to the edge of the opening 111 of the can 110, and then the cover 120 is turned over by the turning mechanism 300 with the middle axis portion of the cover 120 as an axis. Similarly, the cover closing process is the reverse of the cover opening process, and the cover body 120 is firstly turned to the horizontal state by the turning mechanism 300 and then moved to the position for closing the opening 111 by the translation mechanism 200. Because the center of gravity of the cover body 120 is located on the middle shaft part, compared with the cover opening mode of supporting the flip cover by adopting a hydraulic cylinder, the cover opening mode requires smaller supporting force and has lower requirements on the component strength of the turnover mechanism 300 and the power of a power source of the turnover mechanism; in addition, the cover body 120 does not need to be completely translated to a position which is not overlapped with the opening 111, and only needs to be translated to a position where the middle shaft part of the cover body 120 is tangent to the edge of the opening 111, so that the space for meeting the translation of the cover body 120 can be reduced, and the space is saved.
In addition, the central axis portion of the lid 120 includes a central axis and a portion close to the central axis.
Further, the translation mechanism 200 includes horizontal guide rails 210 installed in parallel on both sides of the can 110 and a slider 220 slidably coupled to the horizontal guide rails 210, and the slider 220 is coupled to the cover 120. Compared with the design of the horizontal guide rail 210 on one side, the sliding parts 220 on two sides can disperse the stress of the cover body 120, so as to better support the cover body 120, reduce the burden on the joint of the sliding parts 220 and the cover body 120, and improve the durability of the translation mechanism 200.
Further, the slider 220 is provided with a cover connector 221 and a cylinder 222, the cover connector 221 being connected to the cover 120, and the cylinder 222 being connected to the cover connector 221. The air cylinder 222 is used to drive the cover connection member 221 and the cover 120 to move in the vertical direction. Because the opening 111 of the tank body 110 is provided with the sealing rubber strip, the cover body 120 needs to be lifted to a position where the cover body 120 does not contact the sealing rubber strip through the air cylinder 222, so that the cover body 120 is prevented from rubbing the sealing rubber strip, the sealing rubber strip is prevented from being abraded, and the sealing performance of the well-type vacuum tank is prevented from being damaged. Typically the gap between the cap 120 and the bead of sealant is maintained at 20mm to 30 mm.
Further, the slider 220 is further provided with a spring 223, and the spring 223 is connected with the cover body connecting piece 221; the cylinder 222 works and causes the cover 120 to be tightly attached to the opening 111; the cylinder 222 is released and the spring 223 moves the cover 120 away from the opening 111. In this embodiment, the spring 223 flexibly supports the cover connector 221, and supports the cover 120, so that the gap between the cover 120 and the sealant in the natural state is maintained in the range of 20mm to 30 mm. When the cylinder 222 is activated, the cylinder 222 presses the cover connector 221 and the cover 120 downward to close the opening 111 with the cover 120, and the well-type vacuum tank can be vacuumized. When the pressure of the well-type vacuum tank is relieved to normal pressure, the air cylinder 222 is loosened, the cover body 120 is reset under the action of the elastic force of the spring 223, and positive pressure filling can be prevented.
Further, the sliding member 220 is further provided with a first motor 330 for driving the sliding member 220 to move. The motor is adopted for driving, the driving structure is simple, the maintenance cost is low, and the defect that the working performance of the hydraulic system is greatly influenced by the temperature can be avoided.
Further, the turnover mechanism 300 includes a fixing member 310, a turnover member 320 and a turnover power source 330, wherein the fixing member 310 is fixedly connected to a side surface of the tank 110, and the turnover member 320 is hinged to the fixing member 310. The flipping power source 330 drives the flipping element 320 to rotate.
Referring to fig. 4, further, the turnover member 320 is fixedly connected with a turnover guide rail 321 connected with the horizontal guide rail 210, and the turnover guide rail 321 is provided with a travel switch electrically connected with the turnover power source 330; the slider 220 moves to the roll-over guide rail 321 and triggers the stroke switch, and the roll-over power source 330 drives the roll-over member 320 to roll over together with the slider 220 on the roll-over guide rail 321. It should be noted that the flip-over member 320 is rotated 90 degrees, so that the cover 120 is perpendicular to the plane of the opening 111.
Further, an output shaft of the turning power source 330 is provided with an output gear 332; the bottom surface of the flipper 320 is provided with teeth that engage the output gear 332. Through gear engagement, the flipping power source 330 rotates the flipping element 320.
Further, the turning power source 330 is a second motor, and the second motor is connected with a speed reducer 331; the fixing member 310 includes two trapezoidal blocks 311 respectively located at both sides of the tank 110 and a cross member 312 connecting the two trapezoidal blocks 311, the trapezoidal blocks 311 are provided with bearings, and an output shaft of the tilting power source 330 is installed in the bearings. Similarly, the use of an electric motor as the reverse power source 330 avoids the disadvantages associated with the use of hydraulic systems, as described above. The two trapezoidal blocks 311 and the cross beam 312 bear the overturning power source 330, so that the structure is simple and stable.
In another embodiment of the present invention, a well-type vacuum tank is provided, which includes a tank body 110 having an opening 111 at a top end thereof, a lid body 120 capable of opening and closing the opening 111, and a tank lid control mechanism as described above.
The tank lid control mechanism of this embodiment is the same as above, and therefore the well type vacuum tank has the same advantageous effects as above, and will not be described here.
The above is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and the present invention shall fall within the protection scope of the present invention as long as the technical effects of the present invention are achieved by the same means.
