Description

Technical Field

[0001] This invention belongs to the field of road construction technology, specifically relating to a road paving device for improving the living environment. Background Technology

[0002] The human settlement environment refers to the environment in which humans live. Within this environment, the smoothness and cleanliness of roads are closely related to the convenience of residents' travel and their comfort. In some more remote areas, roads remain uneven and potholed, requiring road paving equipment to repair them. Old, neglected concrete roads may also suffer from severe cracking and deformation, necessitating repaving.

[0003] Plate vibrators are commonly used road paving devices in the process of concrete pavement construction. During concrete paving, concrete raw materials are mixed in a concrete mixer to form a concrete mixture. After the concrete mixture is transported to the paving area, a plate vibrator is used to compact the concrete and simultaneously level it. Existing plate vibrators consist of a vibrating plate and a vibrating motor to provide vibration to the plate. After starting the motor, the plate vibrator is dragged forward or backward at an appropriate speed to vibrate and level the road surface.

[0004] To prevent concrete segregation, plate vibrators should not be used to vibrate the same area of ​​concrete mix for extended periods. For wider paving areas or areas with significant variations in width, these areas need to be divided into multiple rows. By turning or moving the vibrator plate laterally, each row of concrete mix in the paving area can be vibrated and leveled. During this turning or moving, some areas may require longer vibration times. Furthermore, to avoid missed vibrations, adjacent rows of concrete mixes need to have a certain degree of overlap. Concrete in adjacent rows is also prone to prolonged vibration. Both of these excessive vibration times can easily lead to concrete segregation, causing the coarse aggregate in some areas to settle and reducing the overall strength of the concrete pavement. Summary of the Invention

[0005] The purpose of this invention is to provide a road paving device suitable for improving the living environment of people's homes, in order to solve the above-mentioned problems.

[0006] The present invention achieves the above objectives through the following technical solutions:

[0007] A road paving device for improving living environment includes a vibrating mechanism for compacting and leveling concrete mixture. The vibrating mechanism is mounted on a longitudinal traveling mechanism, which drives the vibrating mechanism to move along the road paving direction. The traveling mechanism includes two side-by-side vehicle bodies and a cantilever arm positioned between the two vehicle bodies. The vibrating mechanism includes a lateral moving component movable along the length of the cantilever arm, a lifting component fixed to the lower end of the lateral moving component, and a vibration component positioned below the lifting component. The vibration component is used to vibrate the concrete mixture. The traveling mechanism is assembled before paving the concrete road surface. A corresponding number of cantilever arms are connected according to the actual paving area width to form a crossbeam. Both ends of the crossbeam are fixed to the top beams of the two vehicle bodies. When paving the concrete road surface, the vibrating mechanism suspended on the top beams is slid onto the crossbeams. The vibration component vibrates the concrete mixture. The movement of the two vehicle bodies drives the two top beams and the crossbeam between them to move along the road paving direction, allowing the vibration component to compact and level the concrete simultaneously. The laying area is divided into multiple columns according to the width of the vibrating component. When it is necessary to change the column where the vibrating component is located, the lifting component and the traversing component work together to move the vibrating component to the designated column. The lifting component lifts the vibrating component upward, and then the traversing component moves the vibrating component along the crossbeam to move the vibrating component above the designated column. Finally, the lifting component presses the lower end of the vibrating component down into the concrete mixture of the designated column to avoid over-vibration of some concrete mixtures due to the traversing vibrating component.

[0008] As a further optimization of the present invention, the lifting component is used to adjust the height of the vibration component so that the vibration component separates from the concrete mixture in the paving area during the movement of the vibration component along the cantilever length direction.

[0009] As a further optimization of the present invention, the cantilever is detachably disposed between the two vehicle bodies.

[0010] As a further optimization of the present invention, multiple cantilever arms are provided, and the multiple cantilever arms are fixed together in a detachable connection manner.

[0011] As a further optimization of the present invention, multiple cantilever arms are provided, and the multiple cantilever arms are of different lengths.

[0012] As a further optimization of the present invention, the lateral movement component includes a lifting frame that slides with the cantilever, a gear rotatably disposed inside the lifting frame, and a rotary drive component. The fixed end of the rotary drive component is fixed to the lifting frame, and the output end of the rotary drive component is fixed to the gear. A first rack that meshes with the gear is provided on one side of the cantilever.

[0013] As a further optimization of the present invention, the rotary drive component includes a worm gear fixed to one side of the gear, a worm gear meshing with one side of the worm gear, and a motor for driving the worm gear to rotate.

[0014] As a further optimization of the present invention, the vehicle body includes a chassis, a support frame fixed to the top of the chassis, and a top beam fixed to the inside of the support frame. A second rack corresponding to a gear is fixed on one side of the top beam of one of the vehicle bodies, and a vehicle speed sensor is also provided on one of the vehicle bodies.

[0015] As a further optimization of the present invention, the vibration component is elastically connected to the lifting component, and the vibration component includes a mounting frame, a vibration source fixed to the mounting frame, and a plate fixed to the bottom of the mounting frame.

[0016] As a further optimization of the present invention, the mounting bracket consists of a support and a connecting plate, and the connecting plate is detachably connected to the support.

[0017] The beneficial effects of this invention are as follows:

[0018] 1) This invention uses a vibrating assembly in conjunction with the vehicle body to compact and level the concrete mixture. When it is necessary to change the column where the vibrating assembly is located, the lifting assembly and the lateral moving assembly move the vibrating assembly to the designated column. The lifting assembly lifts the vibrating assembly upwards, and then the lateral moving assembly moves the vibrating assembly along the crossbeam to move it above the designated column. Finally, the lifting assembly presses the lower end of the vibrating assembly down into the concrete mixture of the designated column. This avoids over-vibration of some concrete mixtures when changing the column where the vibrating assembly is located, and prevents the concrete from segregating.

[0019] 2) By installing a vehicle speed sensor and a corresponding controller on the vehicle body, when the controller detects that the vehicle body is traveling at a speed lower than the speed threshold for a long time, the controller sends a control command to the lifting component to raise the vibration component, thereby avoiding excessive vibration of the local paving area caused by the vehicle body not traveling smoothly.

[0020] 3) By setting a first rack and a second rack below the top beam and the spliced ​​split crossbeam, the present invention forms an extended rack that can be meshed with gears and has a variable length, which improves the convenience of storing and transporting the vibration mechanism, and makes the replacement of the vibration area and the movement of the vibration component relative to the vehicle body smoother and more convenient. By driving the gear to rotate through a rotary drive component with locking capability, the lateral displacement of the vibration component is avoided, further improving the vibration effect.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1-3 As shown, a road paving device for improving the living environment includes a vibrating mechanism for compacting and leveling concrete mixture. The vibrating mechanism is movably mounted on a split longitudinal traveling mechanism, which can drive the vibrating mechanism to travel along the road paving direction, which is the length direction of the concrete pavement to be paved. The traveling mechanism includes two vehicle bodies 1 arranged side by side, and a cantilever 2 detachably connected between the two vehicle bodies 1. The vibrating mechanism includes a transverse moving component 3 that can move along the length direction of the cantilever 2, a lifting component 4 fixed at the lower end of the transverse moving component 3, and a vibration component 5 disposed at the lower end of the lifting component 4.

[0031] Please see Figure 3Before laying the concrete pavement, the traveling mechanism is assembled. The vibrating mechanism is suspended from the top beam 13 of one of the vehicle bodies 1 of this traveling mechanism. Multiple cantilever arms 2 are placed on the chassis 11 of one of the vehicle bodies 1. The appropriate number of cantilever arms 2 are connected according to the actual width of the paving area to form a crossbeam. Both ends of this crossbeam are fixed to the top beams 13 of the two vehicle bodies 1 respectively. Specifically, adjacent cantilever arms 2 are fixed with threaded fasteners, and the cantilever arms 2 at both ends of the crossbeam are also fixed to the opposite ends of the two top beams 13 respectively with threaded fasteners.

[0032] When laying concrete pavement, the concrete raw materials are first mixed using a concrete mixer or concrete mixer truck to obtain a concrete mixture. This concrete mixture is then filled into the pre-designated paving area. The vibrating mechanism, suspended on the top beam 13, is then slid onto the crossbeam. (See also...) Figure 1 and Figure 2 The concrete mixture is vibrated by the vibrating assembly 5. The movement of the two vehicle bodies 1 moves the two top beams 13 and the crossbeam between them along the road paving direction, allowing the vibrating assembly 5 to compact and level the concrete simultaneously. The paving area is divided into multiple rows based on the width of the vibrating assembly 5. When it is necessary to change the row of the vibrating assembly 5, the lifting assembly 4, in conjunction with the lateral movement assembly 3, moves the vibrating assembly 5 to the designated row. The lifting assembly 4 lifts the vibrating assembly 5 upwards, and then the lateral movement assembly 3 moves the vibrating assembly 5 along the crossbeam to position it above the designated row. Finally, the lifting assembly 4 presses the lower end of the vibrating assembly 5 down into the concrete mixture of the designated row. This avoids over-vibration of part of the concrete mixture when changing the row of the vibrating assembly 5, preventing concrete segregation.

[0033] Specifically, such as Figure 4 and Figure 5 As shown, in order to improve the smoothness of the lateral movement of the vibrating mechanism, a first rack 6 is fixedly installed at the bottom end of the cantilever 2. The lateral movement component 3 includes a lifting frame 31 that slides with the cantilever 2, a gear 32 that is rotatably installed inside the lifting frame 31, and a rotary drive component. The fixed end of the rotary drive component is fixed to the lifting frame 31, and the output end of the rotary drive component is fixed to the gear 32. The gear 32 meshes with the first rack 6.

[0034] The rotary drive component includes a worm gear 33 fixed to the front side of the gear 32, a worm 34 meshing with the lower side of the worm gear 33, and a motor 35 for driving the worm 34 to rotate. The output shaft of the motor 35 is fixedly connected to the worm 34. The base of the motor 35 is the fixed end of the rotary drive component, and the connection between the worm gear 33 and the gear 32 is the output end of the rotary drive component. In addition, the cantilever 2 and the top beam 13 have the same cross-sectional size and shape, and are both inverted T-shaped with steps on both the front and rear sides. The inner side of the top of the hoisting frame 31 is provided with two sets of hanging wheels, which can roll along the steps on the front and rear sides of the cantilever 2 and the top beam 13, respectively. The vehicle body 1 includes a chassis 11, a support frame 12 fixed to the top of the chassis 11, and a top beam 13 fixed to the inside of the support frame 12. One side of the top beam 13 of one of the vehicle bodies 1 is fixed with a second rack 7 corresponding to the gear 32. When the crossbeam composed of the cantilever 2 is connected to the two top beams 13, several first racks 6 under the crossbeam and the second racks 7 under the top beam 13 are connected as one unit to form an extended rack, and the gear 32 can maintain meshing on the entire rack.

[0035] After the traveling mechanism is assembled, the lateral moving component 3 drives the worm 34 to rotate through the motor 35. Through the meshing of the worm 34 and the worm wheel 33, the worm wheel 33 and the gear 32 are driven to rotate. Through the meshing of the second rack 7 and the gear 32, the gear 32 rotates and moves towards the crossbeam, thereby driving the hoisting frame 31 to slide towards the crossbeam and move the lifting component 4 and the vibration component 5 laterally to the area that needs to be vibrated. Similarly, when changing the column where the vibration component 5 is located, the vibration component 5 can be moved left and right by rotating the motor 35 forward or backward. After the road is paved, the gear 32 moves towards the second rack 7 by rotating the motor 35 backward, thereby moving the vibration component 5 laterally into the support frame 12 of the vehicle body 1, realizing the reset of the vibration component 5. In order to improve the smoothness and convenience of changing the vibration area and moving the vibration component 5 into and out of the vehicle body, the first rack 6 and the second rack 7 are set under the top beam 13 and the spliced ​​split crossbeam to form an extended rack that can be meshed with the gear 32 and has a variable length. This also improves the convenience of storing and transporting the vibration mechanism and saves the space occupied by the lateral moving component 3 and the entire road paving device. The gear 32 is driven to rotate by the worm gear 34 in conjunction with the worm wheel 33 and the drive structure of the worm gear 34, so that the rotation drive component has a locking ability to prevent the plate 53 from shifting laterally during the vibration process, further improving the vibration effect.

[0036] Alternatively, the second rack 7 can be omitted below the top beam 13. In this case, during the process of moving the vibration assembly 5 into the vehicle body 1, after the gear 32 reaches the edge of the first rack 6, the hoisting frame 31 needs to be manually or with the help of a pulling tool to be dragged into the support frame 12. Similarly, during the process of moving the vibration assembly 5 out of the vehicle body 1, the hoisting frame 31 needs to be manually or with the help of a pulling tool to be dragged to the edge of the support frame 12 so that the gear 32 and the first rack 6 can mesh.

[0037] Furthermore, vehicle speed sensors can be installed on one or two vehicle bodies 1, along with corresponding controllers. The vehicle speed sensors are preferably SS40A Hall effect speed sensors. These sensors detect the speed of the vehicle body 1 and transmit the results to the controller. During vibration, if the controller determines that the vehicle body 1 is traveling at a speed below a threshold for an extended period, it sends a control command to the lifting assembly 4 via wireless signal. This causes the lifting assembly 4 to raise the vibration assembly 5, preventing excessive vibration of the local paving area by the vibration assembly 5 due to the vehicle body 1's slow movement. For details, please refer to [link to relevant documentation]. Figure 4 and Figure 6 The lifting assembly 4 includes an upper mounting plate 41 fixed to the hoisting frame 31 and a lower mounting plate 42 located directly below the upper mounting plate 41, as well as an electric telescopic rod 43 fixedly disposed between the two mounting plates 41 and 42. The lower mounting plate 42 of the lifting assembly 4 is elastically connected to the vibration assembly 5. By extending and retracting the electric telescopic rod 43, the lower mounting plate 42 is raised and lowered, thereby adjusting the height of the vibration assembly 5. To improve the stability of the lifting assembly 4, four springs are installed between the four corresponding corners of the two mounting plates 41 and 42. Alternatively, the lifting assembly 4 can be replaced with a cylinder, a hydraulic cylinder, or other devices with telescopic capabilities.

[0038] In addition, the vibration assembly 5 includes a mounting frame 51, a vibration source 52 fixed to the mounting frame 51, and an L-shaped plate 53 fixed to the bottom of the mounting frame 51. The vibration source 52 is preferably a vibration motor. After the vibration motor is started, the vibration is transmitted to the plate 53 through the mounting frame 51, and the plate 53 is used to vibrate the concrete mixture. The vibration motor and the plate 53 have a certain distance to reduce the contamination of its outer shell. Specifically, the mounting frame 51 consists of a bracket 511 and a connecting plate 512. The connecting plate 512 is detachably connected to the bracket 511 by threaded fasteners. The connecting plate 512 is connected to the lower mounting plate 42 of the lifting assembly 4 by a spring to prevent the vibration of the vibration assembly 5 from damaging the lifting assembly 4. A limiting rod is fixed on the connecting plate 512, which passes through the lower mounting plate 42 to limit the rotation of the vibration assembly 5 and prevent the rotation of the plate 53 from having an adverse effect on the vibration effect. In addition, since the connecting plate 512 and the bracket 511 are detachably connected, the direction of the plate 53 can be adjusted by separating the connecting plate 512 and the bracket 511 during the vibration process, thereby improving the convenience of vibration operation.

[0039] In other embodiments, the cantilever 2 can also be configured with varying lengths. In this case, it is not necessary to connect multiple cantilever 2s together. Only a cantilever 2 of appropriate length needs to be selected, and this cantilever 2 can be used as a crossbeam. The two ends of this crossbeam are then fixed to the two top beams 13 to complete the assembly of the traveling mechanism, improving the convenience of the assembly process. It should be noted that this embodiment requires an increase in the total weight and volume of the multiple cantilever 2s, leading to higher transportation costs. The traveling mechanism can also be an integrated structure, i.e., only one cantilever 2 is set, and the cantilever 2 remains fixed to both vehicle bodies 1. This eliminates the need for assembling the traveling mechanism, but this solution is less adaptable to different road paving sites.

[0040] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
