Description

Technical Field

[0001] This utility model relates to the field of highway construction tools, and more specifically, to an asphalt roadside retaining device for highway construction. Background Technology

[0002] In highway asphalt paving, wooden boards are usually used to block the sides of the asphalt to prevent it from overflowing.

[0003] Patent CN222594534U discloses an asphalt roadside retaining device for highway construction. An electric push rod drives a slider to slide within a groove. The slider drives two moving blocks to slide on the surfaces of two guide rods within two moving grooves, limiting the slider's position. When the connecting groove at the bottom of the slider engages with the retaining block, a motor on the mounting base, in conjunction with a bearing, drives a rotating rod to rotate. The rotating rod drives two adjusting blocks to rotate, and the two adjusting blocks drive two limiting posts to rotate and engage with two limiting holes on the surface of the retaining block, fixing it in place. Two electric telescopic rods move the two limiting blocks, exposing the through groove and allowing the retaining block to move downwards, facilitating its installation. However, in use, when the rotating rod rotates, the two adjusting blocks connected to it cannot simultaneously extend into the limiting holes of the retaining block. Furthermore, when the rotating rod rotates, the adjusting blocks are mostly in an inclined state, making it difficult to directly insert them into the limiting holes of the retaining block. Therefore, fixing and limiting the retaining block is difficult, thus affecting its placement. Utility Model Content

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1-6 As shown, this embodiment provides an asphalt roadside retaining device for highway construction, including a base 1, four columns 2 mounted on the base 1, and a top plate 3 mounted on the top of each column 2. A platform 5 is mounted on the base 1 for placing retaining block assemblies 4, each containing several retaining blocks 6. A hoisting structure 8 is also mounted above the platform 5 for hoisting the retaining blocks 6. Two placement cavities 7 are also provided on the base 1, located on opposite sides of the platform 5. After the retaining blocks 6 in the retaining block assembly 4 are hoisted by the hoisting structure, they pass through the placement cavities 7 and are lowered, thus laying the retaining blocks. Movable structures are also provided on both sides of the platform 5 to move the retaining blocks 6 to a preset position above the placement cavities 7 before lowering them, thus preparing for highway asphalt construction.

[0042] In this embodiment, a traveling wheel 11 with brakes is provided under the base 1 to facilitate the movement of the device to the required position for the lowering and laying of the retaining block. Columns 2 are installed at the four corners of the base 1, and a first mounting plate 21 is provided between two adjacent columns 2. Two second mounting plates 31 are also provided in the middle of the lower end face of the top plate 3. A hoisting structure 8 is provided between adjacent first mounting plates 21 and second mounting plates 31 for hoisting the retaining block 6. The hoisting structure is a wheel-axle structure, including a rotating shaft 81 that passes through and is rotatably connected to the first mounting plate 21 via a bearing, and a rotating wheel 82 located at the free end of the rotating shaft 81. The other end of the rotating shaft 81 is rotatably connected to the second mounting plate 31 via a bearing. A rope 83 is wound around the rotating shaft 81, one end of which is fixedly connected to the rotating shaft 81 near the rotating wheel 82, and the free end of the rope 83 is connected to a hook for hooking the retaining block 6.

[0043] Accordingly, such as Figure 5The upper surface of the retaining block 6 is provided with a hanging ring 61. In order to prevent the hanging ring 61 from obstructing the stacking of the retaining blocks 6, a hemispherical recessed groove 64 is formed around the hanging ring. The upper surface of the hanging ring 61 is flush with the upper surface of the retaining block. A first protrusion 62 is provided at one end of the retaining block 6, and a matching first groove 63 is provided at the other end to facilitate the splicing of adjacent retaining blocks.

[0044] In this embodiment, two placement cavities 7 are also provided on both sides of the platform 5 of the base 1. For example... Figure 3 As shown, the placement cavity 7 is a rectangular hollow structure with several equally spaced second protrusions 71 on one side and equally spaced second grooves 72 on the opposite side. The second protrusions 72 are adapted to the first grooves 63 of the stop block 6, and the second grooves 72 are adapted to the first protrusions 62 of the stop block 6. The stop block 6 can be lowered according to the different positions of the second protrusions 71 and second grooves 72 arranged in the placement cavity. The device can be moved to the approximate position of the stop block using the wheels 11, and then the position of the stop block 6 can be finely adjusted according to the positions of the multiple second protrusions 71 and second grooves 72 arranged in the placement cavity 7, thereby facilitating more accurate placement of the stop block.

[0045] In this embodiment, a through hole 32 is also provided in the center of the top plate 3 to facilitate observation and maintenance.

[0046] In this embodiment, a first mounting plate 21 is arranged between two adjacent columns 2, and a third mounting plate 22 is arranged below the first mounting plate 21. Two connecting blocks 51 are arranged on the front and rear sides of the platform 5, respectively. A movable rod 9 is arranged between the connecting block 51 and the third mounting plate 22 for sliding installation of the movable structure. Wherein, as... Figure 2 As shown, the movable structure includes a movable frame 10, with movable blocks 12 connected to both sides of the movable frame 10. Each movable block 12 has a through hole through which a movable rod 9 passes. The two ends of the movable rod 9 are fixed to a third mounting plate 22 and a connecting block 51, respectively. Specifically, the movable frame 10 is a square frame structure with its upper surface sloping downwards from the outside inwards to facilitate the insertion of the retaining block. To facilitate the movement of the movable structure, a handle 13 is also installed on the upper surface of the movable block 12. Pulling the handle 13 allows the movable structure to be moved left and right along the movable rod 9 until it reaches the appropriate position on the placement cavity 7.

[0047] In this embodiment, as Figure 4As shown, the stop block assembly 4 includes a base plate 41 and two limiting flanges 42 fixed to the base plate 41. The two limiting flanges 42 are groove structures with inward openings, and the two limiting flanges 41 are arranged opposite to each other. The space within the two limiting flanges 42 is used to place the stop block 6. The stop block assembly 4 can be placed on the platform 5 of the base 1 using a forklift, or other methods can be used to place the stop block assembly 4 on the platform 5.

[0048] In this embodiment, when using the hoisting structure 8 to hoist the retaining block 6, the hook is attached to the hanging ring 61 of the retaining block 6, and then the rotating wheel 82 is rotated, driving the rotating shaft 81 to rotate, thereby the rope 83 hoists the retaining block 6. Then another construction worker holds the rope 83 or supports the hoisted retaining block 6 and gently moves it so that the retaining block 6 falls into the moving frame. Since the edge of the moving frame 10 is inclined downward, the retaining block 6 can easily enter the moving frame 10. At this time, the operator holds the rotating wheel 82 to stop the rotation of the rotating wheel 82, so that the retaining block 6 pauses in the moving frame 10. Then, the operator holds the handle 13 and moves the moving frame 10 so that the retaining block 6 is above one of the suitable positions in the placement cavity 7. Then, the rotating wheel 82 is rotated again until the retaining block 6 falls to the ground, and then the hook at the end of the rope 83 is removed, thus completing the placement of the retaining block 6. Then, the turntable 82 is rotated in the opposite direction, and the rope 83 is pulled upward to prepare for the hoisting and placement of the next stop block 6.

[0049] In this embodiment, two sets of placement cavities 7 are provided, which allows for the selection of one set of placement cavities 7 for placing the retaining block 6 during construction. If the spacing between the two placement cavities 7 meets the construction conditions, both sets of placement cavities can also be used simultaneously.

[0050] The asphalt roadside retaining device for highway construction provided in this embodiment, when in use, involves rotating the wheel 82 of the hoisting structure, which drives the rotating shaft 81 to rotate, tightening the rope 83 wound on the rotating shaft. The rope then hooks onto the hanging ring 61 of the retaining block 6, lifting the retaining block 6. The lifted retaining block 6 is placed into the movable frame 10. The operator pulls the movable frame 10 left and right along the moving rod 9 using the handle 13, moving the retaining block 6 to a preset position above the placement cavity 7. Continuing to rotate the wheel 82 causes the retaining block 6 to fall from the movable frame 10. The retaining blocks 6 are joined together by the first protrusion 62 and the first groove 63. The second protrusion 71 and the second groove 72 within the placement cavity 7 assist in the positioning and placement of the retaining blocks 6.

[0051] The asphalt roadside retaining device for highway construction provided in this embodiment directly hoists the retaining block using rope 83 and hooks, avoiding the problem in the prior art where the adjusting block is difficult to insert into the limiting hole. By setting up the placement cavity 7 and the movable frame 10, the operator can manually fine-tune the position of the retaining block 6 according to the position of the second protrusion 71 and the second groove 72 in the placement cavity 7, making it easier to place in the preset position.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
