Description

Technical Field

[0001] This application belongs to the field of building technology, specifically relating to an asphalt mixture compaction device. Background Technology

[0002] In the traditional Marshall compaction process, positioning mainly relies on the pre-set retaining rings during equipment manufacturing for initial fixation, thereby ensuring the approximate position of the mold before compaction begins.

[0003] However, during actual compaction, the retaining ring structure can shift due to continuous vibration after prolonged use of the equipment. This makes it difficult to accurately position the mold during placement, hindering the guarantee that the compaction hammer will act absolutely vertically and precisely on the center of the mold in each compaction cycle. Therefore, the poor stability of the limiting structure leads to uneven compaction work on different parts of the sample, resulting in uneven density distribution within the sample and making it difficult to ensure compaction quality. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides an asphalt mixture compaction device. Through the combined design of positioning columns and molding components, the positioning plate and positioning columns work together. Since the positioning columns are positioned corresponding to the compaction components and the force is vertically downward during compaction, the forces on the positioning columns in other directions are much less compared to the method of using retaining rings for limiting, which effectively improves the stability of the positioning structure, ensures that all parts of the sample receive uniform compaction work, and results in a uniform density distribution inside the sample, thereby ensuring the compaction quality.

[0005] The technical effects to be achieved in this application are realized through the following aspects:

[0006] This application provides an asphalt mixture compaction device, including...

[0007] The compaction platform is equipped with positioning posts;

[0008] A compaction component, disposed on the compaction table, is used to compact the asphalt mixture located on the compaction table; the compaction component is disposed opposite to the positioning post; and

[0009] A molding component includes a sleeve and a positioning plate, wherein the sleeve is fitted onto the positioning plate; the positioning plate is provided with positioning holes that are adapted to the positioning pins.

[0010] In some implementations, a fixing component is also included, which is symmetrically arranged on both sides of the positioning post for fixing the molding component.

[0011] In some implementations, the fixing component includes:

[0012] A threaded rod is located on one side of the positioning post; and

[0013] The fixing block has a threaded hole adapted to the threaded rod, through which the threaded rod passes and is connected; the lower end of the fixing block has a fixing groove corresponding to the sleeve, the fixing groove being used to press down part of the sleeve.

[0014] In some implementations, the fixing component includes:

[0015] A fixing rod is provided on one side of the positioning post;

[0016] An elastic element, one end of which is connected to the upper end of the fixed rod;

[0017] A pressure block, connected to the other end of the elastic element, and the fixing rod passing through the pressure block; and

[0018] A control unit is connected to one side of the fixed rod and located at the lower end of the pressure block. The control unit abuts against the pressure block and is used to control the clamping force between the pressure block and the sleeve.

[0019] In some implementations, the control unit includes a connecting rod, a control block, and a handle. The connecting rod is connected to one side of the fixed rod; the control block abuts against the lower end of the pressure block and is threadedly connected to the connecting rod; the handle is connected to the control block.

[0020] In some implementations, the control block has a first end face and a second end face opposite to each other, with the first end face located close to the fixing rod; the diameter of the second end face gradually decreases from the diameter of the first end face.

[0021] In some implementations, the handle is tilted toward the second end face; the plane formed by the control blocks forms an angle α with the central axis of the handle. Preferably, the angle α is 10°-25°.

[0022] In some implementations, the molding component further includes handles symmetrically arranged on both sides of the sleeve.

[0023] In some implementations, the molding component further includes a support plate, the plane of which is perpendicularly connected to the bottom edge of the sleeve.

[0024] In some implementations, the sleeve includes at least one cylindrical body.

[0025] In summary, this application has at least the following advantages:

[0026] The asphalt mixture compaction device provided in this application, through the combined design of positioning posts and molding components, utilizes the interlocking of positioning holes in the positioning plate with the positioning posts. Since the positioning posts are positioned corresponding to the compaction components, and the force is vertically downward during compaction, the forces acting on the positioning posts in other directions are significantly less compared to the method using retaining rings for limiting movement. That is, the retaining ring method controls the sleeve edge of the molding component, while the interlocking of the positioning posts and positioning holes controls the bottom of the molding component. Therefore, the stability of the positioning structure is greatly improved, ensuring uniform compaction work on all parts of the sample, resulting in a uniform density distribution within the sample and ensuring compaction quality. Furthermore, the overall positioning structure is simple, facilitating subsequent maintenance. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0039] Example 1:

[0040] Please see the appendix Figure 1-3 The asphalt mixture compaction device of this application includes a compaction table 1, a compaction component 2, and a molding component 3. The compaction table 1 is provided with a positioning post 11; the compaction component 2 is disposed on the compaction table 1 and is used to compact the asphalt mixture located on the compaction table 1; the compaction component 2 is arranged opposite to the positioning post 11; the molding component 3 includes a sleeve 31 and a positioning plate 32, the sleeve 31 being fitted onto the positioning plate 32; the positioning plate 32 is provided with a positioning hole 321 adapted to the positioning post 11. Preferably, the positioning hole 321 is located at the center of the molding component.

[0041] In this embodiment, the asphalt mixture compaction device first engages the positioning hole 321 of the positioning plate 32 with the positioning post 11, then the sleeve 31 is placed around the positioning plate 32. Alternatively, the sleeve 31 can be placed around the edge of the positioning plate 32 first, and then the positioning post 11 is inserted into the positioning hole 321. The specific sequence can be flexibly changed according to the operator's habits or the specific molding component. Subsequently, the asphalt mixture is poured between the sleeve 31 and the positioning plate 32; then, the compaction component 2 compacts the asphalt mixture in the molding component. Since the positioning post 11 is inserted into the positioning hole 321, the positioning plate 32 is fixed in a position relative to the compaction component 2. The sleeve 31 is fixed by the positioning plate 32 by being fitted onto the positioning plate 32. The structure can achieve mutual positioning, and the overall structure is simple and stable.

[0042] Understandably, compared to using a retaining ring for positioning, since the retaining ring controls the edge of the sleeve 31 of the molding component, while the positioning post 11 and the positioning hole 321 engage to control the bottom of the molding component, the force is vertically downward during compaction. Therefore, the force on the positioning post 11 in other directions is significantly less compared to using a retaining ring. This greatly improves the stability of the positioning structure, ensuring uniform compaction work on all parts of the sample, thereby achieving a uniform density distribution within the sample and ensuring compaction quality. Furthermore, the overall positioning structure is simple, facilitating later maintenance and manufacturing.

[0043] In addition, the molding components adopt a separately set sleeve 31 and positioning plate 32. During the demolding process, the positioning plate 32 can be pushed to remove the sample, which improves the convenience of demolding.

[0044] In some embodiments, a fixing component 4 is further included. The fixing component 4 is symmetrically arranged on both sides of the positioning post 11 and is used to fix the molding component. By using the fixing component 4, during the compaction process, the fixing component 4 fixes the upper end of the sleeve 31 in the molding component, which can realize the combined fixation of the upper and lower parts of the sleeve 31, greatly improving the stability of the sleeve 31 during the compaction process.

[0045] For details, please refer to the appendix. Figure 4 The fixing component 4 includes a threaded rod 41 and a fixing block 42. The threaded rod 41 is located on one side of the positioning post 11. The fixing block 42 has a threaded hole that matches the threaded rod 41, through which the threaded rod 41 passes. The lower end of the fixing block 42 has a fixing groove 421 corresponding to the sleeve 31, which is used to press down part of the sleeve 31. Preferably, the fixing block 42 is cylindrical.

[0046] With the fixing component 4, the fixing method can be achieved by rotating and adjusting the fixing block 42, which allows the fixing block 42 to move up and down along the threaded rod 41. After the asphalt mixture is filled into the sleeve 31, the fixing groove 421 is abutted against the upper end of the sleeve 31 by rotating the fixing block 42, thus fixing the upper part of the sleeve 31 with the fixing block 42. This greatly improves the stability during the compaction process and ensures that all parts of the sample receive uniform compaction work. Moreover, in this structure, the fixing operation of the fixing component 4 is easy and convenient.

[0047] Example 2:

[0048] The difference between this embodiment and Embodiment 1 lies in the structure of the fixing component 4. Please refer to [link / reference]. Figures 5-6 .

[0049] like Figure 5In this embodiment, the fixing component 4 includes a fixing rod 43, an elastic element 44, a pressure block 45, and a control unit 46. The fixing rod 43 is located on one side of the positioning post 11; one end of the elastic element 44 is connected to the upper end of the fixing rod 43; the pressure block 45 is connected to the other end of the elastic element 44, and the fixing rod 43 passes through the pressure block 45; the control unit 46 is connected to one side of the fixing rod 43 and located at the lower end of the pressure block 45, and the control unit 46 abuts against the pressure block 45. The control unit 46 is used to control the clamping force between the pressure block 45 and the sleeve 31. The control unit 46 abuts against the pressure block 45, and the control unit 46 can slightly lift the pressure block 45. The size of the hole through which the fixing rod 43 passes through the pressure block 45 is 2-4 times larger than the size of the horizontal interface of the fixing rod 43, facilitating the tilting and fixing of the pressure block 45 through the control unit 46.

[0050] In this embodiment, when the pressure block 45 needs to press down on the sleeve 31, the control unit 46 moves closer to the fixing rod 43, causing the pressure block 45, which is in contact with the control unit 46, to move from a position away from the fixing rod 43 to a position closer to the fixing rod 43. This causes the other end of the pressure block 45 to descend until it presses down on the upper end of the sleeve 31. It is understood that the elastic element 44 allows the pressure block 45 to move up and down at both ends, ensuring the flexibility of the pressure block 45's movement. Furthermore, when fixing the sleeve 31, the pressure exerted by the pressure block 45 on the sleeve 31 is flexible, avoiding excessive pressure that could damage the sleeve 31, reducing wear on the sleeve 31, and extending the durability of the sleeve 31.

[0051] In this structure, the upper part of the sleeve 31 is fixed by applying flexible pressure to the sleeve 31 through the pressure block 45, which can also reduce the wear of the sleeve 31 by pressure. It can simultaneously achieve the stability of compaction operation and extend the durability of the sleeve 31.

[0052] In some embodiments, such as Figure 6 The control unit 46 includes a connecting rod 461, a control block 462, and a handle 463. The connecting rod 461 is connected to one side of the fixed rod 43; the control block 462 abuts against the lower end of the pressure block 45 and is threadedly connected to the connecting rod 461; the handle 463 is connected to the control block 462. With this configuration, the control unit 46 moves closer to or further away from the fixed rod 43 as follows: rotating the handle 463 causes the control block 462 to move on the connecting rod 461, thus moving closer to or further away from the fixed rod 43, thereby controlling the pressure block 45 to press down or move upward. That is, when the control block 462 moves from further away from the fixed rod 43 to closer to the fixed rod 43, the pressure block 45 moves downward, pressing the sleeve 31; conversely, it releases the sleeve 31. The structure is compact and ingenious, and the overall operation is simple and convenient.

[0053] In some embodiments, the control block 462 has a first end face 4621 and a second end face 4622 opposite to each other, with the first end face 4621 located near the fixing rod 43; the diameter of the second end face 4622 gradually decreases from the diameter of the first end face 4621. Preferably, the control block 462 is a frustum-shaped control block 462. This design reduces the overall weight of the control block 462, facilitating easy control of the control block 462 by the handle 463. In addition, the shape of the control block 462 ensures that a portion of the first end face 4621 always abuts against the lower end of the pressure block 45, avoiding a large contact area between the control block 462 and the pressure block 45 during the release of the sleeve 31 stage, thereby reducing friction and improving the ease with which the handle 463 operates the control block 462.

[0054] In some embodiments, the handle 463 is inclined toward the second end face 4622; the plane formed by the control block 462 forms an angle α with the central axis of the handle 463. Preferably, the angle α is 10°-25°. With this arrangement, the handle 463 is oriented away from the sleeve 31, which increases the space for operating the handle 463, facilitates the adjustment of the handle 463, and makes operation convenient and easy.

[0055] Example 3:

[0056] The difference between this embodiment and Embodiment 2 is that, please refer to... Figures 7-8 In this embodiment, the forming component 3 also includes handles 34 symmetrically arranged on both sides of the sleeve 31. With this arrangement, after the asphalt mixture compaction operation is completed, the forming component can be directly lifted by the handles 34, making it easy to move the forming component out of the compaction table 1, which is convenient for operation.

[0057] In some embodiments, the molding component 3 further includes a support plate 33, the plane of which is perpendicularly connected to the bottom edge of the sleeve 31. The support plate 33 protrudes 1-3 cm towards the center of the sleeve 31. By providing the support plate 33, the problem of the positioning plate 32 falling off due to insufficient adhesion of the asphalt mixture is avoided when the molding component is removed from the compaction table 1. This ensures the stability of the positioning plate 32 during movement, guarantees the compaction quality of the asphalt mixture, reduces uneven density distribution within the sample due to external influences, and improves the compaction quality of the asphalt mixture.

[0058] In some embodiments, the sleeve 31 includes at least one cylindrical body 311. Preferably, two cylindrical bodies 311 can be used to form the sleeve 31. This arrangement can reduce the demolding difficulty of the large sleeve 31, allowing for individual disassembly, reducing demolding deformation problems, and improving demolding quality.

[0059] If the sleeve 31 includes two cylinders 311, the upper end of the cylinder 311 that contacts the positioning plate 32 is provided with a limiting hole, and the lower end of the other cylinder 311 is provided with a limiting post that matches the limiting hole. During assembly, the limiting post is inserted into the limiting hole to further improve the stability of the assembly and ensure the compaction quality.
