Description

Technical Field

[0001] The utility model relates to the field of highway maintenance, in particular to a novel shock-absorbing structure of a sweeper. Background Art

[0002] After a highway is built and opened to traffic, its quality of use will gradually decrease due to the wear and impact of wheels, erosion and weathering by natural forces such as rainstorms, floods, sandstorms, ice and snow, sunlight, and ice melt, as well as human damage and certain defects left over from construction. Therefore, after a highway is built and opened to traffic, maintenance measures must be taken and it must be continuously updated and improved. The maintenance of the highway requires the use of sweepers to clean up the garbage on the ground.

[0003] The existing sweepers are heavy and have complex use environments, so the wheels need to be damped. Ordinary damping springs are used to damp the wheels, but the compression effect of the springs cannot achieve the best damping effect, and the reset effect is not good. Long-term compression use can easily lead to poor spring rebound effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the spring compression damping effect is poor and the spring rebound elasticity is not good.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a new shock-absorbing structure of a sweeper, including a base plate, a fixed crossbeam is arranged at the bottom of the base plate, and the fixed crossbeam has two groups arranged in a front-to-rear symmetrical shape, and the left and right sides of the fixed crossbeam are fixedly connected with linkage plates, and the linkage plate is arranged in an "L" shape, and the linkage plate is threadedly connected with a connecting bolt on the side of the linkage plate away from the fixed crossbeam, and the connecting bolt is fixedly connected with a downward pressing connecting block on the side close to the linkage plate, and the bottom of the downward pressing connecting block is fixedly connected with a sliding rod, and the inside of the sliding rod is slidably connected with a limiting rod near the bottom end position, and the bottom of the limiting rod is fixedly connected with a supporting connecting block, and the sliding rod and the limiting rod are externally sleeved with an umbrella-shaped shock-absorbing spring, the top of the umbrella-shaped shock-absorbing spring is fixedly connected to the bottom of the downward pressing connecting block, and the bottom of the umbrella-shaped shock-absorbing spring is fixedly connected to the top of the supporting connecting block, the support connecting block is rotatably connected with a bearing bolt, and the outside of the bearing bolt is rotatably connected with a tire near the side of the linkage plate.

[0006] The above technical solution realizes that the bulk structure of the umbrella-shaped shock-absorbing spring can be compressed to the maximum extent, which solves the problem that the previous ordinary-shaped springs cannot achieve maximum shock absorption due to compression and mutual squeezing, and improves the shock-absorbing and buffering effect of the umbrella-shaped shock-absorbing spring.

[0007] The utility model is further configured such that the front end of the linkage plate abuts against a rotating plate near the bottom, the rotating plate and the linkage plate are rotatably connected with a rotating bolt, the rotating plate abuts against one side of the supporting connecting block on the side away from the linkage plate, and the rotating plate is rotatably connected to the outside of the bearing bolt.

[0008] The utility model is further configured that the left and right sides of the pressing connection block are rotatably connected with stretching rotating blocks, the side of the stretching rotating block away from the pressing connection block is fixedly connected with a telescopic rod, and a connecting rotating component is arranged on the top of the telescopic rod.

[0009] The utility model is further configured such that the connecting and rotating assembly includes a compression block, the compression block is fixedly connected to the top of the telescopic rod, a positioning shell is sleeved on the outside of the compression block, a fixed rotating block is fixedly connected to the top of the positioning shell, and the fixed rotating block is rotatably connected to the inside of the fixed plate.

[0010] The utility model is further configured that a shock-absorbing cross beam is fixedly connected to the bottom of the base plate near the left and right sides, the fixed plate is fixedly connected inside the shock-absorbing cross beam, and the shock-absorbing cross beam is designed in an inverted "mountain" shape.

[0011] Through the above technical solution, two pairs of auxiliary springs cooperate with the umbrella-shaped shock-absorbing spring to perform shock absorption simultaneously, which solves the problem of using only a single umbrella-shaped shock-absorbing spring for shock absorption, and the inability to return to the original position after being compressed to the limit position due to metal fatigue, thereby improving the service life of the umbrella-shaped shock-absorbing spring.

[0012] The utility model is further configured that an auxiliary spring is sleeved on the outside of the telescopic rod, one end of the auxiliary spring is fixedly connected to the bottom of the compression block, and the auxiliary spring is fixedly connected to the bottom end position inside the positioning shell away from the bottom of the compression block.

[0013] The utility model is further configured such that a cleaning shell is fixedly connected to the bottom of the shock-absorbing cross beam, the bottom of the cleaning shell is designed to be open, a cleaning wheel is rotatably connected inside the cleaning shell, and the cleaning wheel is arranged near the center position of the bottom of the base plate.

[0014] The utility model is further configured such that a power supply collection assembly is fixedly connected to the top of the base plate, an operating handle is arranged behind the power supply collection assembly, and the operating handle is fixedly connected to the top of the base plate near the rear end.

[0015] Through the above technical solution, the sweeping wheel can sweep all the dust into the power collection assembly, which solves the problem that the previous sweeper has a large shape, resulting in a limited range of use of the vehicle and an inability to clean small locations, thereby increasing the range of use of the sweeper.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model solves the problem that the single spring structure in the past could not achieve the ultimate compression and the reset effect of the umbrella-shaped shock-absorbing spring was poor under the condition of metal fatigue, thereby improving the ultimate compression and reset effect of the umbrella-shaped shock-absorbing spring.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

The left and right sides of the fixed crossbeam 7 are fixedly connected with linkage plates 25, and the linkage plates 25 are arranged in an "L" shape. The side of the linkage plate 25 away from the fixed crossbeam 7 is threadedly connected with a connecting bolt 17, and the side of the connecting bolt 17 close to the linkage plate 25 is fixedly connected with a downward pressing connecting block 16, and the bottom of the downward pressing connecting block 16 is fixedly connected with a sliding rod 18, and the inside of the sliding rod 18 is slidably connected with a limiting rod 19 near the bottom end, and the bottom of the limiting rod 19 is fixedly connected with a supporting connecting block 21, and the sliding rod 18 and the limiting rod 19 are sleeved with an umbrella-shaped shock-absorbing spring 20 on the outside, and the top of the umbrella-shaped shock-absorbing spring 20 is fixedly connected to the downward pressing connecting block 1 6 bottom, the bottom of the umbrella-shaped shock-absorbing spring 20 is fixedly connected to the top of the supporting connection block 21, the inside of the supporting connection block 21 is rotatably connected with a bearing bolt 22, the outside of the bearing bolt 22 is rotatably connected to the tire 8 near the linkage plate 25, the front end of the linkage plate 25 is abutted against a rotating plate 23 near the bottom position, the rotating plate 23 and the linkage plate 25 are rotatably connected with a rotating bolt 24, the rotating plate 23 is abutted against the side of the supporting connection block 21 away from the linkage plate 25, the rotating plate 23 is rotatably connected to the outside of the bearing bolt 22, the left and right sides of the pressing connection block 16 are rotatably connected with the stretching rotating block 15, the stretching rotating block 15 is fixedly connected to the telescopic rod 13 away from the pressing connection block 16, the top of the telescopic rod 13 is provided with a connecting rotating assembly, and the connecting rotating assembly includes A compression block 12 is fixedly connected to the top of the telescopic rod 13. A positioning shell 11 is sleeved outside the compression block 12. A fixed rotating block 10 is fixedly connected to the top of the positioning shell 11. The fixed rotating block 10 is rotatably connected to the inside of the fixed plate 9. When working, when the tire 8 moves, the cleaning of the top of the bottom plate 1 will cause the collected garbage to accumulate on the top of the bottom plate 1, thereby making the weight of the top of the bottom plate 1 heavier, and thus pressing down the linkage plate 25. At this time, the ground and the tire 8 squeeze the umbrella-shaped shock-absorbing spring 20, and the rotating plate 23 will rotate outside the linkage plate 25 by rotating the bolt 24. The bulk structure of the umbrella-shaped shock-absorbing spring 20 can ensure the extreme contraction of the umbrella-shaped shock-absorbing spring 20 when pressed down. When the umbrella-shaped shock-absorbing spring 20 is pressed down, the linkage plate 25 and the connecting bolt 17 The compression block 12 will squeeze the auxiliary spring 14 for shock absorption. Such a result design will not cause the annular structure of the shock-absorbing beam 2 to squeeze each other and be inconvenient to shrink. When the heavy object on the top of the bottom plate 1 is removed, the auxiliary spring 14 pushes the compression block 12 and the positioning shell 11 inside the positioning shell 11, thereby stretching the telescopic rod 13, allowing the telescopic rod 13 to drive the stretching rotating block 15 and the downward pressing connecting block 16 to reset. The reset of the downward pressing connecting block 16 will stretch the umbrella-shaped shock-absorbing spring 20 to reset the umbrella-shaped shock-absorbing spring 20 to its original position, thereby ensuring that the umbrella-shaped shock-absorbing spring 20 will not be unable to reset to the specified position due to metal fatigue.

[0025] A shock-absorbing crossbeam 2 is fixedly connected near the left and right sides of the bottom of the bottom plate 1, and a fixed plate 9 is fixedly connected inside the shock-absorbing crossbeam 2. The shock-absorbing crossbeam 2 is designed in an inverted "mountain" shape. An auxiliary spring 14 is sleeved on the outside of the telescopic rod 13. One end of the auxiliary spring 14 is fixedly connected to the bottom of the compression block 12. The auxiliary spring 14 is fixedly connected to the bottom end of the positioning shell 11 away from the bottom of the compression block 12. A cleaning shell 3 is fixedly connected to the bottom of the shock-absorbing crossbeam 2. The bottom of the cleaning shell 3 is designed to be open. A cleaning wheel 4 is rotatably connected inside the cleaning shell 3. The cleaning wheel 4 is arranged near the center of the bottom of the bottom plate 1. A power supply collector is fixedly connected to the top of the bottom plate 1. Assembly 5, an operating handle 6 is arranged at the rear of the power collection assembly 5, and the operating handle 6 is fixedly connected to the top of the base plate 1 near the rear end. During operation, when the base plate 1 is used, the base plate 1 can be pushed by the operating handle 6, so that the tire 8 drives the base plate 1 to move, and the open structure at the bottom of the cleaning shell 3 can ensure that the cleaning wheel 4 is in contact with the ground. At this time, the spiral structure of the cleaning wheel 4 can sweep the garbage on the ground into each part of the power collection assembly 5, and the power collection assembly 5 can also provide kinetic energy to the cleaning wheel 4 to make the cleaning wheel 4 rotate, and after the cleaning is completed, the garbage can be taken out from the inside of the power collection assembly 5 for cleaning.

[0026] When the utility model is in use, when the tire 8 is moving, the cleaning of the top of the bottom plate 1 will cause the collected garbage to accumulate on the top of the bottom plate 1, thereby making the weight of the top of the bottom plate 1 heavier, and thus pressing down the linkage plate 25. At this time, the ground and the tire 8 squeeze the umbrella-shaped shock-absorbing spring 20, and the rotating plate 23 will rotate outside the linkage plate 25 by means of the rotating bolt 24, and the bulk structure of the umbrella-shaped shock-absorbing spring 20 can ensure the extreme contraction of the umbrella-shaped shock-absorbing spring 20 when pressed down. When the umbrella-shaped shock-absorbing spring 20 is pressed down, the linkage plate 25 and the connecting bolt 17 will move downward. At this time, the downward pressure of the downward pressing connecting block 16 will drive the stretching rotating block 15 to stretch the telescopic rod 13, so that the compression block 12 squeezes the auxiliary spring 14 for shock absorption. Such a result design will not cause the problem that the annular structures of the shock-absorbing beam 2 are squeezed against each other and are inconvenient to contract. When the heavy object on the top of the bottom plate 1 is removed, the auxiliary spring 14 is in the positioning shell 11. The compression block 12 and the positioning shell 11 are pushed internally, thereby stretching the telescopic rod 13, so that the telescopic rod 13 drives the stretching rotating block 15 and the pressing connecting block 16 to reset, and the resetting of the pressing connecting block 16 will stretch the umbrella-shaped shock-absorbing spring 20 to reset the umbrella-shaped shock-absorbing spring 20 to the original position, thereby ensuring that the umbrella-shaped shock-absorbing spring 20 will not be unable to reset to the specified position due to metal fatigue. When using the base plate 1, the base plate 1 can be pushed by the operating handle 6, so that the tire 8 drives the base plate 1 to move, and the open structure at the bottom of the cleaning shell 3 can ensure that the cleaning wheel 4 is in contact with the ground. At this time, the spiral structure of the cleaning wheel 4 can sweep the garbage on the ground into the power collection assembly 5, and the power collection assembly 5 can also provide kinetic energy to the cleaning wheel 4 to make the cleaning wheel 4 rotate. After cleaning, the garbage can be taken out from the power collection assembly 5 for cleaning.
