Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a highway pavement widening and reinforcement device. Background Technology

[0002] Widening roads can effectively alleviate urban traffic congestion, improve road efficiency, and reduce traffic accidents, which is of great significance to urban construction and economic development.

[0003] When widening a road surface, the main method is to pour concrete on both sides or one side of the road surface to be widened. In order to prevent the poured concrete from overflowing, a processing device needs to be installed at the boundary of the road surface widening.

[0004] For example, Chinese patent document CN219342772U discloses a device for widening and reinforcing the side of a high embankment road surface, including a baffle. A fixing rod assembly is provided on one side of the baffle, and the fixing rod assembly includes a fixing block, a lifting screw hole, a fixing screw, a positioning screw hole, a movable sleeve, a support plate, a positioning bolt, and a ground spike.

[0005] In the above technical solution, multiple reinforcement devices can be connected by the locking blocks and slots set at both ends of the baffle to ensure compatibility with the length of the widened road. However, in actual use, it was found that the length of the baffle is constant. If it is necessary to reduce the number of reinforcement devices used, the baffle needs to be lengthened. However, lengthening the baffle increases its lateral footprint, making it inconvenient to store. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a highway pavement widening and reinforcement device that can increase the length of the baffle to reduce the number of reinforcement devices used, thereby improving the efficiency of connecting multiple processing devices and facilitating the storage of the reinforcement devices.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a highway pavement widening and reinforcement device, comprising a baffle, the baffle comprising a base and an extension portion, the extension portion being symmetrically arranged below the base, a paving device being provided between the extension portion and the base, the paving device comprising a rotating mechanism and a lifting mechanism, the rotating mechanism being used to drive the two extension portions on both sides to move towards each other or away from each other, so that the two sides retract inward or expand outward, the lifting mechanism being used to make the surface of the base flush with the surface of the extension portion after the two sides of the extension portion expand outward, the lifting mechanism being used to make the surface of the base flush with the surface of the extension portion.

[0008] The present invention is further configured such that: the rotating mechanism includes a base located at the center of the base, a transmission arm is rotatably connected to the bottom of the base, and centrally symmetrical transmission links are provided on both sides of the transmission arm. One end of the transmission link is rotatably connected to the end of the transmission arm, and the other end is rotatably connected to the extension part.

[0009] The present invention is further configured such that: the two extended portions on both sides serve as the first connecting side and the second connecting side respectively, and the first connecting side and the second connecting side are respectively fixed with a sliding groove and a slider, the slider being coupled to the sliding groove and being able to slide along the extension direction of the sliding groove to form a sliding fit between the two.

[0010] The present invention is further configured such that: the lifting mechanism includes guide holes through both sides of the transmission arm, a slidable guide rod is provided in the guide holes, the end of the guide rod is fixed to the base, an annular guide groove is provided on the base, the annular guide groove is provided with a downwardly recessed slot, a connecting rod is fixed at the bottom of the base, the end of the connecting rod facing the base serves as the coupling end, the coupling end is arc-shaped, the coupling end is coupled to the annular guide groove, and can move from the high end to the low end or from the low end to the high end of the slot to drive the base to lift.

[0011] The present invention is further configured such that: a support plate is fixed on the surface of the extension part, and the support plate is provided with a through hole for the fixing cone to be driven in.

[0012] The present invention is further configured such that: the first connecting side is provided with a protruding card block, and the second connecting side is provided with a recessed card groove, wherein the card groove is adapted to the card block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The baffle consists of a base and extensions on both sides of the base. The extensions are connected to the base via a flattening device. This device allows the extensions to move back-to-back, expanding them outwards and increasing the baffle's length. This reduces the number of reinforcement devices required, indirectly improving the efficiency of assembling and disassembling multiple processing devices. Furthermore, by moving the extensions towards each other, they can be retracted inwards to stack with the base, preventing an increase in the baffle's lateral (length) footprint. Therefore, this effectively solves the technical problem in existing technologies where lengthening the baffle increases its lateral footprint and makes storage difficult. This improves the efficiency of assembling and disassembling multiple processing devices while facilitating the storage of reinforcement devices. Attached Figure Description

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 3 As shown, this utility model discloses a highway pavement widening and reinforcement device, including a baffle 2. The baffle 2 consists of a base 21 and two extensions 22 symmetrically arranged on both sides of the base 21. An approximately triangular support plate 1 is fixed on the surface of each extension 22 (the side facing away from the pavement to be widened). The support plate 1 is provided with a through hole 101 for a fixing cone to be driven into. After the surface of the baffle 2 is aligned with the boundary of the pavement to be widened, the baffle 2 can be fixed by driving a fixing cone into the through hole 101. This allows the baffle 2 to fix the side of the pavement while also limiting its position to prevent the poured concrete from overflowing from the boundary of the pavement to be widened.

[0023] In this embodiment, a flattening device is provided between the extension part 22 and the base part 21. The flattening device includes a rotating mechanism and a lifting mechanism. The rotating mechanism is used to drive the two extension parts 22 to move towards each other or away from each other. In this way, after the two extension parts 22 are unfolded outward by the rotating mechanism, the length of the baffle 2 can be increased, thereby reducing the number of reinforcement devices used and indirectly improving the efficiency of disassembling and assembling multiple processing devices. In addition, by moving the two extension parts 22 towards each other, the two extension parts 22 can be retracted inward to stack with the base part 21. This can prevent the lateral (length direction of the baffle 2) floor space of the baffle 2 from increasing, so as to facilitate the storage of the reinforcement device.

[0024] After the lifting mechanism extends outward from the two side extensions 22, the surface of the base 21 is flush with the surface of the extension 22, which reduces the seepage of cast concrete from the junction of the extension 22 and the base 21.

[0025] like Figures 4 to 5 As shown, the rotating mechanism includes a base 31 located at the center of the base 21. A transmission arm 32 at the bottom of the base 31 is rotatably connected to the base 31 via a bearing, so that the base 31 does not rotate with the transmission arm 32. The transmission arm 32 is provided with centrally symmetrical transmission links 33 on both sides. One end of the transmission link 33 is hinged to the end of the transmission arm 32 through a pin hole, and the other end is hinged to the extension part 22. When the transmission arm 32 rotates around the center, the transmission link 33 drives the extension parts 22 on both sides to move towards each other or away from each other, so that the extension parts 22 on both sides can retract inward or expand outward.

[0026] Furthermore, the two extension portions 22 serve as the first connecting side and the second connecting side, respectively. The first connecting side is fixed with a slide groove 5, and the second connecting side is fixed with a slider 6. The slider 6 is coupled to the slide groove 5 and can slide along its extension direction, thus ensuring that the two extension portions 22 remain stable when they are extended or retracted.

[0027] The lifting mechanism includes guide holes 41 that pass through both sides of the transmission arm 32. A slidable guide rod 42 is provided in the guide hole 41. The end of the guide rod 42 is fixed to the base 21. An annular guide groove 43 is provided on the base 31. The annular guide groove 43 has a downwardly recessed slot 44, which is approximately V-shaped. A connecting rod 45 is fixed to the bottom of the base 21. The connecting rod 45 is located at the end facing the base 31 as the coupling end. The coupling end is embedded in the annular guide groove 43. When the transmission arm 32 rotates, the coupling end moves from the high end to the low end of the slot 44 along the annular guide groove 43. Since the guide rod 42 is coupled to the guide hole 41 and one end is fixed to the base 21, the transmission arm 32 can push the guide rod 42 to drive the base 21 to rotate. As the base 21 rotates, the connecting rod 45 can move along the annular guide groove 43. When it moves to the low end of the slot 44, the height of the connecting rod 45 decreases, which can drive the base 21 to decrease and make the guide rod 42 slide downward (towards the side of the road to be widened) along the guide hole 41, so that the base 21 is flush with the surface of the extension part 22.

[0028] Similarly, when the coupling end moves from the lower end to the upper end of the slot 44 along the annular guide groove 43, the base 21 can be driven to rise by the increase in height of the connecting rod 45. Therefore, when it is necessary to unfold or retract the extension parts 22 on both sides, it is only necessary to pull the extension parts 22 on both sides outward or push them inward to make the transmission arm 32 rotate in different directions.

[0029] In addition, the coupling end of the connecting rod 45 is arc-shaped, which reduces the friction force on the connecting rod 45 during its movement, thereby facilitating the unfolding and retraction of the extension part 22.

[0030] Finally, after the extension section 22 is fully extended, the protruding locking block 7 provided on the first connecting side and the locking groove 8 provided on the second connecting side that is adapted to the locking block 7 can enable the baffles 2 in adjacent processing devices to be spliced ​​together by locking their respective locking blocks 7 into the corresponding locking grooves 8, thus enabling the connection between multiple reinforcement devices.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
