[0003] Chinese patent CN112681235A discloses a concrete paving device for water conservancy engineering canal construction, capable of uniformly paving, vibrating and homogenizing the slurry, and compacting the concrete, completing a series of operations in a coordinated manner. However, some canals have curved surfaces between their sidewalls and bottoms, and the aforementioned concrete paving device cannot effectively pave on curved surfaces, requiring improvement. Utility Model Content

[0004] This utility model provides a concrete paving machine that can adapt to the curved surface between the channel sidewall and the channel bottom for concrete paving.

[0005] This utility model provides a concrete paving machine, including a paving frame and a paving plate disposed on one side of the paving frame. One bottom surface of the paving frame and one bottom surface of the paving plate are both arc-shaped. The paving frame includes an outer frame and a partition disposed inside the outer frame. The partition has through holes for concrete flow.

[0006] In one embodiment, a connecting mechanism is provided on one side of the outer frame. The connecting mechanism includes a fixed rod, a connecting column, and an elastic element. One end of the fixed rod is connected to the side of the outer frame. The connecting column passes through the fixed rod and one end of the connecting column is connected to the paving slab. The elastic element is disposed between the fixed rod and the paving slab and is sleeved on the surface of the connecting column.

[0007] In one embodiment, a vibration mechanism is further provided on one side of the outer frame. The vibration mechanism includes a mounting bracket, a first driver, a connecting shaft, an eccentric block, and a tapping plate. One end of the mounting bracket and one end of the first driver are both connected to one side of the outer frame. The connecting shaft is disposed on the mounting bracket and connected to the first driver. The eccentric block is disposed on the connecting shaft. The tapping plate is disposed on the surface of the paving slab and connected to the eccentric block.

[0008] In one embodiment, the first driver is a dual-axis motor, and the two output terminals of the first driver are respectively connected to one of the connecting shafts.

[0009] In one embodiment, the number of eccentric blocks on both sides of the first driver is the same.

[0010] In one embodiment, the connecting column includes a column body and a limiting part. The column body passes through the fixing rod, and the end of the column body away from the limiting part is connected to the paving slab. The limiting part is located on the side of the fixing rod away from the paving slab, and the diameter of the limiting part is larger than the diameter of the column body.

[0011] In one embodiment, a walking mechanism is provided at both ends of the outer frame. The walking mechanism includes a protective cover, rollers and a track. The protective cover is rotatably connected to the outer frame. The rollers are disposed inside the protective cover. The track is laid on the ground for the rollers to move.

During the paving operation, the arc-shaped end of the paving frame and the paving slab is placed at the channel bottom, while the non-arc-shaped end is placed at the top of the channel sidewall. The concrete injected into the paving frame is transported downwards through the through holes between the partitions under the action of gravity, so that the entire interior of the paving frame is filled with concrete.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a concrete paving machine of one embodiment includes a paving frame 1 and a paving plate 2 disposed on one side of the paving frame 1. The bottom surface of one end of the paving frame 1 and the bottom surface of one end of the paving plate 2 are both arc-shaped. The paving frame 1 includes an outer frame 11 and a partition 12 disposed inside the outer frame 11. The partition 12 has through holes 13 for concrete flow.

[0027] By setting one bottom surface of the paving frame 1 and one bottom surface of the paving slab 2 to be curved, the curved surface between the channel sidewall and the channel bottom can be well adapted. During the paving operation, the curved end of the paving frame 1 and the paving slab 2 is placed at the channel bottom, while the non-curved end is placed at the top of the channel sidewall. The concrete injected into the paving frame 1 is transported downwards through the through holes 13 between the partitions 12 under the action of gravity, so that the interior of the paving frame 1 is filled with concrete. The paving slab 2 then smooths the concrete flowing out from the bottom of the paving frame 1, thereby completing the concrete paving of one side of the channel.

[0028] Furthermore, a connecting mechanism 3 is provided on one side of the outer frame 11. The connecting mechanism 3 includes a fixing rod 31, a connecting column 32, and an elastic element 33. One end of the fixing rod 31 is connected to the side of the outer frame 11, and a fixing rod 31 is provided at both ends of the outer frame 11. The connecting column 32 passes through the fixing rod 31, and one end of the connecting column 32 is connected to the paving slab 2. The elastic element 33 is disposed between the fixing rod 31 and the paving slab 2 and is sleeved on the surface of the connecting column 32. The paving slab 2 is not rigidly connected to the outer frame 11. The connecting mechanism 3 allows the paving slab 2 to vibrate up and down to a certain amplitude, thereby enabling it to pat the surface of the concrete and ensure the density and uniformity of the concrete.

[0029] Specifically, a vibration mechanism 4 is also provided on one side of the outer frame 11. The vibration mechanism 4 includes a mounting frame 41, a first driver 42, a connecting shaft 43, an eccentric block 44, and a knocking plate 45. One end of the mounting frame 41 and one end of the first driver 42 are connected to one side of the outer frame 11. The connecting shaft 43 is set on the mounting frame 41 and connected to the first driver 42. The eccentric block 44 is set on the connecting shaft 43. The knocking plate 45 is set on the surface of the paving plate 2 and connected to the eccentric block 44.

[0030] The elastic element 33 applies a certain tension to the paving slab 2, causing the paving slab 2 to always tend to move closer to the fixed rod 31. The eccentric block 44 can periodically apply a certain pressure to the paving slab 2, causing the paving slab 2 to periodically tend to move away from the fixed rod 31. When the pressure applied by the eccentric block 44 decreases, the paving slab 2 moves towards the fixed rod 31. When the pressure applied by the eccentric block 44 increases, the paving slab 2 moves away from the fixed rod 31, thereby realizing the periodic vibration of the paving slab 2.

[0031] The first driver 42 is used to drive the connecting shaft 43 to rotate, causing the eccentric block 44 on the connecting shaft 43 to rotate, thereby driving the tapping plate 45 and the paving plate 2 to vibrate periodically, so that the paving plate 2 can compact the concrete flowing from the bottom of the paving frame 1, thereby improving the paving effect of the concrete.

[0032] Furthermore, the first driver 42 is a dual-axis motor, and the two output ends of the first driver 42 are respectively connected to a connecting shaft 43, so that the two connecting shafts 43 can maintain synchronous rotation while using a shorter connecting shaft 43, which is beneficial to suppress the deformation of the connecting shaft 43 and improve the transmission efficiency.

[0033] like Figure 2 As shown, the number of eccentric blocks 44 on both sides of the first driver 42 is the same, which makes the load on the two output shafts of the first driver 42 tend to be consistent, thus improving the stability of the vibration mechanism 4 during operation.

[0034] like Figure 3 As shown, the connecting column 32 includes a column body 321 and a limiting part 322. The column body 321 passes through the fixing rod 31, and the end of the column body 321 away from the limiting part 322 is connected to the paving slab 2. The limiting part 322 is located on the side of the fixing rod 31 away from the paving slab 2, and the diameter of the limiting part 322 is larger than the diameter of the column body 321. By setting the limiting part 322 with a larger diameter, the connecting column 32 can be prevented from detaching from the fixing rod 31, so that the paving slab 2 can only vibrate within a certain range.

[0035] like Figure 1 and Figure 4 As shown, both ends of the outer frame 11 are equipped with a traveling mechanism 5. The traveling mechanism 5 includes a protective cover 51, rollers 52, and a track 53. The protective cover 51 is rotatably connected to the outer frame 11. The rollers 52 are disposed inside the protective cover 51, and the track 53 is laid on the ground for the rollers 52 to move. In this embodiment, the rollers 52 are electrically driven. When the rollers 52 are started, they can roll along the track 53, thereby driving the paving frame 1 and the paving slab 2 to move as a whole. Since the protective cover 51 and the outer frame 11 can rotate relative to each other, the traveling mechanism 5 can adapt to channels with different inclines.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, a finishing mechanism 6 is also provided on one side of the outer frame 11. The finishing mechanism 6 includes a support frame 61, a finishing machine 62, and a lifting assembly 63. The lifting assembly 63 is mounted on the support frame 61 and connected to the finishing machine 62, which is located on the side of the paving slab 2 away from the outer frame 11. The finishing machine 62 can perform finishing operations on the concrete on the channel sidewall after vibration, so that the concrete surface achieves a smooth and flat effect. The lifting assembly 63 is used to adjust the position of the finishing machine 62 so that the finishing machine 62 applies appropriate pressure to the concrete.

[0037] Specifically, the lifting assembly 63 includes a second driver 631, a mounting plate 632, a lead screw 633, an adjusting plate 634, a first connecting rod 635, and a second connecting rod 636. The second driver 631 is disposed on the surface of the mounting plate 632 and connected to the lead screw 633. The lead screw 633 passes through the adjusting plate 634 and is threadedly connected to the adjusting plate 634. The first connecting rod 635 passes through the adjusting plate 634, and its two ends are connected to the mounting plate 632 and the support frame 61, respectively. The second connecting rod 636 passes through the support frame 61, and its two ends are connected to the adjusting plate 634 and the light collector 62, respectively. When the second driver 631 drives the lead screw 633 to rotate, since the support frame 61 is fixed, the adjusting plate 634 will move up or down along the lead screw 633. The first connecting rod 635 provides guidance for the movement of the adjusting plate 634, improving the stability of the adjusting plate 634 during movement. Since the adjusting plate 634 drives the second connecting rod 636 to move up and down in the support frame 61, and the light receiver 62 is fixed at the bottom of the second connecting rod 636, the position of the light receiver 62 can also be adjusted.

[0038] Furthermore, the second driver 631 includes a motor 6311 and a reducer 6312, with the reducer 6312 connected to the output end of the motor 6311 and the lead screw 633. To achieve better light collection, the light collectors 62 are arranged closely and are numerous, while the adjusting plate 634 also has a considerable weight. In this embodiment, a reducer 6312 is placed between the motor 6311 and the lead screw 633 to amplify the torque of the motor 6311, enabling the lifting assembly 63 to smoothly adjust the position of the light collectors 62. In this embodiment, the reducer 6312 adopts a worm gear structure.
