Description

Technical Field

[0001] The utility model relates to the technical field of road construction, and more specifically, to a paving device for road construction. Background Art

[0002] Road construction refers to paving roads, or repairing roads when they are damaged and have potholes. When repairing roads, concrete needs to be injected into the potholes to fill them, thereby completing the repair of the road. After injecting concrete into the potholes, a paving device needs to be used to ensure that the concrete is flush with the road. However, when injecting concrete into the potholes with existing paving devices, workers need to hold a concrete spraying pipe, which increases the labor intensity of the workers and cannot precisely control the position of concrete injection, resulting in concrete spraying out of the potholes. Therefore, in response to this problem, how to design a paving device for road construction has become a problem that we currently need to solve. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a paving device for road construction. By setting a spherical guide member and a connecting rod, the connecting rod can drive the spherical guide member to move through a handle. Since the spherical guide member can slide arbitrarily on the inner side of the annular limit frame, the flexibility of the discharge pipe can be improved, so that concrete can be completely injected into the pothole, avoiding insufficient injection or overflow, thereby solving the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paving device for road construction, comprising a main body, a support frame fixedly installed on one side of the main body, an annular limit frame fixedly installed on one end of the support frame, a spherical guide member rotatably connected to the inner side of the annular limit frame, a limiting cylinder fixedly installed inside the spherical guide member, a connecting rod slidably connected to the inner side of the limiting cylinder, a spring provided on the top of the limiting cylinder, the spring fixedly installed on the outside of the connecting rod, a handle fixedly installed on the top end of the connecting rod, and a discharge pipe fixedly installed on the bottom end of the connecting rod.

[0005] In a preferred embodiment, a delivery pipe is provided on one side of the main body, and the delivery pipe is connected to the discharge pipe.

[0006] In a preferred embodiment, a support plate is fixedly mounted on one side of the support frame, and an electric cylinder is fixedly mounted on the inner side of the support plate.

[0007] In a preferred embodiment, a mounting bracket is fixedly mounted on the output end of the electric cylinder, and a motor is fixedly mounted on the inner side of the mounting bracket.

[0008] In a preferred embodiment, a rotating shaft is fixedly mounted on the output end of the motor, and the rotating shaft is rotatably connected to the inside of the mounting bracket.

[0009] In a preferred embodiment, a connecting bracket is fixedly mounted on the output end of the rotating shaft, and a positioning rod is slidably connected to the interior of the mounting bracket.

[0010] In a preferred embodiment, the positioning rod is inserted into the interior of the connecting frame, and a paving board is fixedly installed on the bottom of the connecting frame.

[0011] The technical effects and advantages of this utility model are:

[0012] 1. The utility model provides a spherical guide and a connecting rod. The direction of the discharge pipe can be adjusted by holding the handle. The connecting rod drives the spherical guide to move accordingly. Since the spherical guide can slide arbitrarily on the inner side of the annular limit frame, the direction in which the discharge pipe can move is greatly increased, thus avoiding the phenomenon of insufficient concrete injection. In addition, the discharge pipe is supported by the spherical guide, and workers do not need to hold the concrete spraying pipe by hand, thereby reducing the labor intensity of workers.

[0013] 2. The utility model sets a paving board. After the concrete is injected, the electric cylinder is started to drive the mounting frame to descend so that the paving board contacts the ground. At this time, the main body is moved forward and the paving board contacts the concrete to push and spread the concrete so that the concrete fully fits the potholes. At the same time, the positioning rods on both sides are removed, and the motor is started to drive the rotating shaft to rotate, so that the paving board rotates to rotate and spread the concrete, so that the concrete can be kept flat with the road surface.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Refer to the instruction manual Figure 1-3 ,like Figure 1 As shown, a paving device for road construction according to an embodiment of the present invention comprises a main body 1, a support frame 2 is fixedly mounted on one side of the main body 1, as shown in FIG. Figure 2 As shown, an annular limiting frame 3 is fixedly installed at one end of the support frame 2, and a spherical guide member 4 is rotatably connected to the inner side of the annular limiting frame 3. A limiting cylinder 5 is fixedly installed inside the spherical guide member 4, and a connecting rod 6 is slidably connected to the inner side of the limiting cylinder 5. A spring 7 is provided on the top of the limiting cylinder 5, and the spring 7 is fixedly installed on the outer side of the connecting rod 6. Figure 1 As shown, a handle 8 is fixedly installed on the top end of the connecting rod 6, a discharge pipe 9 is fixedly installed on the bottom end of the connecting rod 6, and a conveying pipe 10 is connected to one side of the main body 1, and the conveying pipe 10 is connected to the discharge pipe 9.

[0020] It should be noted that, when constructing a pothole on the road, the main body 1 is moved so that the discharge pipe 9 is located above the pothole. At this time, the concrete in the main body 1 can be transported into the discharge pipe 9 through the delivery pipe 10 by starting the main body 1, and flows out of the discharge pipe 9 and falls into the pothole to be repaired. At this time, the direction of the discharge pipe 9 can be adjusted by supporting the handle 8, and the connecting rod 6 will drive the spherical guide 4 to move accordingly. Since the spherical guide 4 can slide arbitrarily on the inner side of the annular limit frame 3, the direction in which the discharge pipe 9 can move is greatly increased, avoiding the injection of concrete. Insufficient phenomena occur, and the discharge pipe 9 is supported by the spherical guide 4, and the staff does not need to hold the concrete spraying pipe by hand. At the same time, by pressing the handle 8, the connecting rod 6 can slide downward, and the spring 7 contracts, thereby extending the discharge pipe 9. When the pothole is large and deep, the discharge pipe 9 can be pulled closer to the pothole, so that the concrete injection is more comprehensive, and at the same time, the phenomenon of concrete overflowing from the pothole or concrete spraying outside the pit is avoided. When injecting concrete into road potholes, the convenience of concrete injection can be improved and the labor intensity of workers can be reduced.

[0021] Further, such as Figure 1 As shown, a support plate 11 is fixedly installed on one side of the support frame 2, an electric cylinder 12 is fixedly installed on the inner side of the support plate 11, and a mounting frame 13 is fixedly installed on the output end of the electric cylinder 12. Figure 3As shown, a motor 14 is fixedly mounted on the inner side of the mounting frame 13, a rotating shaft 15 is fixedly mounted on the output end of the motor 14, the rotating shaft 15 is rotatably connected to the inside of the mounting frame 13, a connecting frame 16 is fixedly mounted on the output end of the rotating shaft 15, and a positioning rod 17 is slidably connected to the inside of the mounting frame 13, and the positioning rod 17 is inserted into the inside of the connecting frame 16, as shown in FIG. Figure 1 As shown, a paving board 18 is fixedly mounted on the bottom of the connecting frame 16 .

[0022] It should be noted that, after the concrete is injected, the mounting frame 13 is driven down by starting the electric cylinder 12, so that the paving plate 18 contacts the ground. At this time, the main body 1 is moved forward, and the paving plate 18 contacts the concrete, and the concrete is pushed and spread, so that the concrete fully fits the potholes. At the same time, the positioning rods 17 on both sides are removed, and the rotating shaft 15 is driven to rotate by starting the motor 14, so that the paving plate 18 rotates to rotate and spread the concrete, so that the concrete can be kept flat with the road surface.
