Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1 As shown:

[0025] A concrete pavement leveling device includes symmetrically arranged lifting mechanisms 1 and a mounting plate 2 movably connected to the lifting mechanisms 1 via a connecting rod. A roller body 4 is installed on one side of two sets of lifting mechanisms 1 close to each other, and a vibration mechanism 3 is installed between the roller body 4 and the mounting plate 2.

[0026] In this implementation scheme: the existing device {publication (announcement) number}: CN218861272U discloses an adjustable concrete pavement leveling device for highway construction. The lifting mechanism 1 and the vibration mechanism 3 in the present application document adopt the same technical means in this prior art. This technical means will not be repeated here one by one. This application makes further improvements on this existing subject. For details, please refer to the disclosed technology below; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the above-mentioned design is convenient for leveling roads of different heights and improving flexibility when used, but this device cannot adjust the spacing of the device according to roads of different widths. When leveling roads of different widths, devices of different sizes need to be used, thereby increasing manufacturing costs, thereby having a low practical range and reducing the use effect of the device." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, an adjustment component 5 is added to the present application document.

[0027] It should be noted that the accessories used by the lifting mechanism 1 and the vibration mechanism 3 have been disclosed by publication number CN218861272U, and their use effects can refer to publication number CN218861272U (that is, "vibration motor, U-shaped frame, guide column, bearing, support spring, support tube, cylinder, protective cover, roller, handle, contact plate, pressure roller, slide groove and slider components" disclosed in this prior art).

[0028] More specifically:

[0029] like Figure 1-Figure 5 As shown:

[0030] An adjusting assembly 5 is installed between the two groups of lifting mechanisms 1, and the adjusting assembly 5 includes a fixing plate 501 arranged on the side where the two groups of mounting plates 2 are close to each other, a bidirectional telescopic rod 502 fixed and symmetrically arranged between the two groups of fixing plates 501, and a first adjusting rod 503 fixed on the surface of one group of fixing plates 501, a second adjusting rod 504 is fixed on the surface of the other group of fixing plates 501, and a plurality of groups of equidistantly arranged jacks 505 are provided on the surface of the second adjusting rod 504, one end of the first adjusting rod 503 is slidably connected with a latch 506, and a compression spring 507 is wound around the surface of the latch 506, one group of fixing plates 501 is internally threadedly connected with an adjusting bolt 508, one end of the adjusting bolt 508 is rotatably connected to the surface of one group of mounting plates 2 through a bearing, and the other group of fixing plates 501 is fixedly connected to the mounting plate 2. A splicing roller 510 is arranged between the two groups of roller bodies 4, and plugs 511 are fixed at both ends of the splicing roller 510. A slot 512 adapted to the plug 511 is provided on the surface of the roller body 4, and the first adjusting rod 503 and the second adjusting rod 504 are fitted together. One end of the pin 506 is inserted into one of the groups of sockets 505. A symmetrically arranged limit rod 509 is fixed on the surface of the fixed plate 501, and a movable groove adapted to the limit rod 509 is provided on the surface of the mounting plate 2. The limit rod 509 and the mounting plate 2 are slidably connected through the movable groove. An inclined chamfer is provided on the end of the plug 511 away from the splicing roller 510. The splicing roller 510 can be multiple groups, and the lengths of the multiple groups of splicing rollers 510 are different. The plugs 511 at both ends of the multiple groups of splicing rollers 510 with different lengths are always adapted to the slot 512.

[0031] In this embodiment: the concrete pavement leveling device, when in use, for leveling roads of different widths, it is necessary to adjust the width of the device, then measure the width of the road, pull the latch 506, and then stretch the compression spring 507 until the latch 506 is disengaged from the insertion hole 505 provided in the second adjustment rod 504, thereby releasing the lock of the first adjustment rod 503 and the second adjustment rod 504, and then pull the two sets of lifting mechanisms 1 outward to adjust the width until the overall length of the outermost ends of the two sets of roller bodies 4 is greater than the width of the road, then release the latch 506, at this time the compression spring 507 contracts, and drives the latch 506 to be inserted into the insertion hole 505, completing the position locking of the first adjustment rod 503 and the second adjustment rod 504, and then install the splicing roller 510 of appropriate length according to the spacing between the two sets of roller bodies 4, at this time the splicing roller 510 is located between the two sets of roller bodies 4, and one end of the plug 511 on the splicing roller 510 is inserted into the slot 512 of one set of roller bodies 4;

[0032] Since the end of the plug 511 away from the splicing roller 510 is provided with an inclined chamfer, the diameter of one end of the plug 511 is smaller than the inner diameter of the slot 512, so that the plug 511 can be inserted into the slot 512 more quickly;

[0033] At the same time, the adjusting bolt 508 is rotated to drive the mounting plate 2 to move. At the same time, the mounting plate 2 is limited by the setting of the limit rod 509, so that the mounting plate 2 is more stable during the movement, thereby reducing the distance between the two sets of lifting mechanisms 1, and the lifting mechanism 1 drives the roller body 4 to move, so that the two sets of roller bodies 4 squeeze the splicing roller 510, so that the roller body 4 and the two ends of the splicing roller 510 are tightly fitted, thereby completing the width adjustment. Through this device, it is possible to adapt to roads of different widths for leveling operations, and there is no need to manufacture devices of different sizes to cope with roads of different widths, thereby reducing the manufacturing cost, having a wide range of applications, improving the use effect of the device, and meeting actual use needs.

[0034] It should be noted that the two sets of roller bodies 4 and the spliced ​​rollers 510 do not need to be completely compatible with the road width. It is only necessary to make the overall length of the roller bodies 4 and the spliced ​​rollers 510 greater than the road width to meet the usage requirements.

[0035] Going further;

[0036] In an optional embodiment, a placement groove 514 is provided on the surface of the first adjusting rod 503 near the side of the latch 506, and a push rod 513 is arranged inside the placement groove 514. One end of the push rod 513 is rotatably connected to the first adjusting rod 503 through a rotating shaft, and a symmetrically arranged return torsion spring 515 is wound around the surface of the rotating shaft. The two ends of the return torsion spring 515 are respectively fixedly connected to the first adjusting rod 503 and the push rod 513. A limiting slot 516 is provided on the surface of the latch 506, and the two ends of the compression spring 507 are respectively fixedly connected to the latch 506 and the first adjusting rod 503. The limiting slot 516 is designed as a conical slot structure, and the maximum diameter of the limiting slot 516 is greater than the diameter of the push rod 513.

[0037] In this embodiment: when the second adjustment rod 504 and the first adjustment rod 503 are unlocked, the top rod 513 is folded, thereby driving the return torsion spring 515 to produce elastic deformation, and at the same time, the pin 506 is pulled until the top rod 513 is inserted into the limiting slot 516 to temporarily lock the position of the pin 506. Therefore, when the width of the two sets of lifting mechanisms 1 are adjusted, there is no need for the staff to hold the pin 506 all the time, which further improves the use effect of the device. Since the limiting slot 516 is designed with a conical structure, the maximum diameter of the limiting slot 516 is greater than the diameter of the top rod 513, which facilitates the top rod 513 to be inserted into the limiting slot 516 more conveniently and quickly.

[0038] The working principle and use process of the utility model: When the concrete pavement leveling device is used, it is necessary to adjust the width of the device for leveling roads of different widths, and then measure the width of the road, pull the latch 506, and then stretch the compression spring 507, until the latch 506 is disengaged from the insertion hole 505 provided in the second adjustment rod 504, thereby releasing the lock of the first adjustment rod 503 and the second adjustment rod 504, at this time, by folding the top rod 513, and then driving the reset torsion spring 515 to produce elastic deformation, while pulling the latch 506, until the top rod 513 is inserted into the limiting slot 516, the position of the latch 506 is temporarily locked, so that when the two When the two lifting mechanisms 1 are adjusted in width, there is no need for the staff to hold the latch 506 all the time, which further improves the use effect of the device. Since the limit slot 516 is designed in a conical structure, the maximum diameter of the limit slot 516 is larger than the diameter of the push rod 513, so that the push rod 513 is more conveniently and quickly inserted into the limit slot 516. When the second adjustment rod 504 and the first adjustment rod 503 are unlocked, the two lifting mechanisms 1 are then pulled outward to adjust the width until the overall length of the outermost ends of the two groups of roller bodies 4 is larger than the width of the road. At this time, the latch 506 is pulled to release the engagement of the push rod 513. At this time, the reset torsion spring 515 rebounds and drives the push rod 513 to reset and fold to place. The latch 506 is then released, and the compression spring 507 contracts at this time, driving the latch 506 to be inserted into the insertion hole 505, completing the position locking of the first adjustment rod 503 and the second adjustment rod 504, and then installing a spliced ​​roller 510 of a suitable length according to the spacing between the two groups of roller bodies 4. At this time, the spliced ​​roller 510 is located between the two groups of roller bodies 4, and one end of the plug 511 on the spliced ​​roller 510 is inserted into the slot 512 of one group of roller bodies 4. Since the end of the plug 511 away from the spliced ​​roller 510 is provided with an inclined chamfer, the diameter of one end of the plug 511 is smaller than the inner diameter of the slot 512 at this time, so that the plug 511 can be inserted into the slot 512 more quickly. , and at the same time, the adjusting bolt 508 is rotated to drive the mounting plate 2 to move. At the same time, the mounting plate 2 is limited by the setting of the limit rod 509, so that the mounting plate 2 is more stable during the movement, thereby reducing the distance between the two sets of lifting mechanisms 1, and the lifting mechanism 1 drives the roller body 4 to move, so that the two sets of roller bodies 4 squeeze the splicing roller 510, so that the roller body 4 and the two ends of the splicing roller 510 are tightly fitted, thereby completing the width adjustment. Through this device, it is possible to adapt to roads of different widths for leveling operations, and there is no need to manufacture devices of different sizes to cope with roads of different widths, thereby reducing the manufacturing cost, having a wide range of applications, improving the use effect of the device, and meeting actual use needs.
