Detailed Description
As shown in fig. 1 and 2, the suction cup collision prevention device of the washing and sweeping vehicle is arranged below a chassis of the washing and sweeping vehicle and comprises a suction cup 1, a connecting frame 2, a tension spring 3, an iron chain 4, a suction pipe 5 and a roller 6. The link 2 is stainless steel, and the upper end of two links 2 all welds on chassis 7, and the lower extreme of two links 2 hinges respectively in the preceding lateral wall of sucking disc 1 and the central authorities of back lateral wall to support sucking disc 1 balancedly. Two extension spring 3 are installed on chassis 7 along vertically, and two extension spring 3 are located the left and right sides of link 2 symmetrically, extension spring 3's bottom fixed connection iron chain 4, the bottom of iron chain 4 is installed on the top surface of sucking disc 1, when the left end of sucking disc 1 meets the barrier and upwards rocks, sucking disc 1's right-hand member passes through iron chain 4 and draws extension spring 3 of right-hand member downwards, make sucking disc 1 smoothly pass through the barrier, then extension spring 3 on right side upwards resets the right-hand member of sucking disc rapidly, make sucking disc 1 keep balanced state, do benefit to the dust that the sucking disc steadily siphoned away ground. Because the specifications of the two extension springs 3 and the iron chain 4 are the same, when the road surface is flat, the tension of the two extension springs 3 on the two ends of the sucker 1 is the same, and the sucker 1 can keep a horizontal balance state.
As shown in fig. 2, the upper and lower ends of the suction pipe 5 are fixedly mounted on the base plate 7 and the suction cup 1, respectively. An air inlet is arranged on the base plate 7, and a dust collecting chamber 10 communicated with the air inlet is arranged above the base plate 7; the center of the top of the sucker 1 is provided with an air suction hole 8, a truncated cone-shaped air suction cover 9 is arranged in the sucker 1, the bottom of the air suction cover 9 is open, and the air suction cover 9 is communicated with the air suction hole 8; the upper and lower ends of the suction pipe 5 are respectively communicated with the air inlet hole and the suction hole 8, so that dust enters the dust collection chamber 10 through the suction pipe 5. The tube of the suction tube 5 is in a telescopic accordion shape, so that the tube of the suction tube 5 can be automatically stretched or extruded along with the shaking of the sucker 1, and the reliability of the connection between the suction tube 5 and the chassis 7 and the sucker 1 is ensured. The bottom end of the suction pipe 5 is in threaded connection with the suction hole 8, so that the sucking disc 1 is convenient to mount.
Both ends are equipped with transition slope 11 respectively about sucking disc 1, and the bottom of transition slope 11 forms the toper structure that stands upside down to the inboard slope of sucking disc, and transition slope 11 can make sucking disc 1 more smoothly pass through the road surface barrier, tip and ground scraping when avoiding sucking disc 1 to rock to the protection sucking disc is not damaged. The shaft is installed along the fore-and-aft direction of sucking disc at both ends about sucking disc 1, installs gyro wheel 6 on the shaft, and the bottom protrusion in the below of transition slope 11 of gyro wheel 6 rolls friction between gyro wheel 6 and the barrier, avoids barrier direct collision sucking disc 1's transition slope 11, further protects sucking disc 1 not damaged by the barrier, prolongs its life.
The working process of the device is as follows: in the process that the washing and sweeping vehicle advances towards the left side, the sucker 1 below the chassis 7 is kept in a horizontal state, and under the action of negative pressure in the dust and debris collecting chamber 10, the sucker 1 sucks away dust on the ground. When there is bellied barrier on the ground, the gyro wheel 6 on sucking disc 1 left rolls over the barrier, and the left end of sucking disc 1 is by jack-up simultaneously, and extension spring 3 on sucking disc right side is by the downwardly stretching, and the gyro wheel on sucking disc right side is through the barrier, and the right-hand member of sucking disc 1 is by jack-up this moment, and extension spring 3 on sucking disc left side is by the downwardly stretching. When the sucker 1 completely passes through the obstacle, the left extension spring 3 quickly resets the sucker 1, so that the sucker 1 is kept in a horizontal state. The washing and sweeping vehicle continues to move leftwards, and the suction disc continues to suck dust.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
