Pavement paving structure of water permeable bricks

Abstract

The utility model relates to a pavement paving structure of water permeable bricks, which comprises a lifting rod, and four limiting plates are arranged below the lifting rod and respectively and accurately correspond to four side edges of the water permeable bricks. Wherein the two limiting plates I are fixedly connected to the mounting box, the other two limiting plates II are connected with the mounting box in a sliding mode, and the included angle between every two limiting plates is a right angle. The distance between the limiting plate II and the limiting plate I can be adjusted by sliding the limiting plate II, so that the structure can be conveniently moved to the outer side of the water permeable brick for paving. After paving is completed, when the water permeable bricks are paved, the limiting plates II are moved to ensure that the water permeable bricks are out of contact, the limiting plates I are reserved in the cluster, and the accurate thickness control can ensure that gaps between the adjacent water permeable bricks are uniform and consistent. The detailed construction process not only improves the aesthetic property of the pavement, but also ensures the full play of the water permeability, and is beneficial to rapid permeation of rainwater and reduction of accumulated water on the pavement, thereby improving the efficiency of an urban drainage system.

Description

Technical Field

[0001] This utility model relates to the field of road paving equipment technology, and in particular to the road paving structure of permeable bricks. Background Technology

[0002] With the development of urban construction, permeable brick pavements have been widely used in urban roads, squares, and other places. Permeable bricks have excellent water permeability, which can effectively alleviate urban flooding and replenish groundwater. During the paving process of permeable bricks, it is not only necessary to accurately move the permeable bricks to the designated positions, but also to strictly meet the distance requirements between the permeable bricks to ensure the overall quality and permeability of the pavement.

[0003] Currently, there are several technical devices on the market to assist in the installation of permeable bricks. Most of these existing devices are equipped with lifting rods, under which multiple limiting plates are mounted. Through the interaction of clamping force and frictional resistance between the limiting plates and the permeable bricks, the position of the permeable bricks can be flexibly adjusted using the lifting rod. Some existing devices can also use ropes, screws, or other drive mechanisms to change the position of the limiting plates, thereby clamping and fixing the permeable bricks, facilitating the movement of the permeable bricks by operators.

[0004] However, existing technologies have significant drawbacks. They focus excessively on the clamping and moving functions of permeable bricks, neglecting the stringent requirements for brick spacing in permeable brick paving. In practical use, the multiple limiting plates in existing devices often move synchronously, their function limited to clamping and fixing the permeable bricks, failing to precisely control the gap between adjacent permeable bricks during paving. If the spacing between permeable bricks is inconsistent after installation, it directly affects the aesthetics and permeability of the pavement, thus weakening the overall quality and effectiveness of the permeable brick pavement. Therefore, there is an urgent need for a new paving device capable of precisely controlling the distance between adjacent permeable bricks while moving them. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention proposes a permeable brick pavement structure. This device enables automatic laying of permeable bricks and adjusts the distance between adjacent bricks through its structural characteristics, ensuring that the functional requirements of the permeable bricks are met. This device not only overcomes the limitation of existing technologies where permeable bricks can only be moved, but also effectively solves the problem of operators finding it difficult to precisely control the spacing between adjacent permeable bricks during laying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The permeable brick pavement structure includes a lifting rod. A limiting plate with an inverted L-shaped vertical projection is installed on the lower side of the lifting rod. The permeable brick is located inside the L-shaped openings of multiple limiting plates. There are four limiting plates, each corresponding to one of the four sides of the permeable brick. A mounting box is fixedly connected to the lower end of the lifting rod. Of the four limiting plates, two are fixedly connected to the mounting box (limiting plate I), and the other two are slidably connected to the mounting box (limiting plate II). The included angle between the two limiting plates I is 90 degrees, and the included angle between the two limiting plates II is also 90 degrees. A driving component is installed on the lower side of each of the two limiting plates II, and the driving component is located inside the mounting box and movably connected to it.

[0008] Preferably, the driving component includes a follower rod, which is rotatably connected to the mounting box, and the outer side of the follower rod is keyed to a follower gear, which meshes with the corresponding limiting plate II for transmission.

[0009] Preferably, a synchronization component is provided between the two driving components. The synchronization component includes a bevel gear set, and the two follower rods are connected by meshing transmission through the bevel gear set. One of the follower rods is keyed to the driven gear on its outer side.

[0010] Preferably, a drive gear is meshed and driven on one side of the driven gear, the drive gear is rotatably connected to the mounting box, and the transmission ratio between the drive gear and the driven gear is not equal to one. A rack is meshed and driven on one side of the drive gear, the rack is slidably connected to the lifting rod, a pull ring is fixedly connected to the upper end of the rack, and the upper end of the rack protrudes from the lifting rod, while the lower end of the rack abuts against the permeable brick.

[0011] Preferably, the portion of each limiting plate that abuts against the permeable brick is projected as a trapezoidal structure on a vertical plane, and the upper width of the portion of each limiting plate that abuts against the permeable brick is smaller than its lower width.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model relates to a permeable brick installation device, characterized by the precise configuration of four limiting plates corresponding to the four sides of the permeable brick. Two limiting plates I are fixedly connected to the installation box, while the remaining two limiting plates II are connected to the installation box via a sliding mechanism. The included angles between limiting plates I and II are both set to 90 degrees. Through the interaction between limiting plates I and II, the sliding adjustment of limiting plate II is achieved, thereby changing its distance from limiting plate I. This ingenious design allows the operator to easily move it to the outside of a single permeable brick, greatly simplifying the paving process. After paving, the outer limiting plate II is moved to separate it from the permeable brick cluster, causing the individual permeable brick to disengage from the limiting plate, while limiting plate I remains inside the permeable brick cluster. The precise thickness design of limiting plate I allows for strict control of the gap between adjacent permeable bricks, successfully overcoming the problem of accurately controlling the gap between permeable bricks in existing technologies. This design ensures the consistency of the gaps between permeable brick pavers, which not only improves the aesthetics and permeability of the pavement, but also significantly enhances the overall quality and service life of the permeable brick pavement.

[0020] 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.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and 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 this utility model.

[0022] like Figure 1 As shown, the permeable brick pavement structure is consistent with the existing technical device, which includes a lifting rod 1 and multiple limiting plates 2 below the lifting rod 1.

[0023] Furthermore, by limiting the projection of each limiting plate 2 in the vertical direction to be an inverted L-shaped structure, the L-shaped structure design of the limiting plate 2 allows the clamping force and frictional resistance between the limiting plate 2 and the permeable brick 3 to work together when the permeable brick 3 is placed in the L-shaped opening of these limiting plates 2, so that the lifting rod 1 can effectively control the position change of the permeable brick 3.

[0024] like Figure 1 , Figure 2 As shown, compared with the prior art, the significant feature of this device is that there are four limiting plates 2, which are precisely matched with the four sides of the permeable brick 3.

[0025] Furthermore, a mounting box 5 is fixedly connected to the lower end of the lifting rod 1. Of the four limiting plates 2, two limiting plates 2 fixedly connected to the mounting box 5 are defined as limiting plates I 201, and the other two limiting plates 2 slidably connected to the mounting box 5 are defined as limiting plates II 202. The included angle between limiting plates I 201 and between limiting plates II 202 is 90 degrees.

[0026] The design of this device cleverly utilizes the interaction between limiting plate I 201 and limiting plate II 202. By sliding limiting plate II 202, the distance between limiting plate I 201 and limiting plate II 202 (i.e., the distance between limiting plate I 201 and limiting plate II 202 in the same vertical plane) can be adjusted. This design facilitates the movement of limiting plate 2 to the outside of the permeable brick 3, simplifying the laying process. After laying is completed, the outer limiting plate II 202 is moved to detach it from the cluster, and the individual permeable brick 3 is released accordingly. Limiting plate I 201 remains in its original position, and its thickness determines the gap between adjacent bricks.

[0027] It should be noted that this device is not suitable for laying the permeable bricks 3 at the edge (i.e., the permeable bricks 3 located between the permeable brick cluster and the curbstone), as the permeable bricks 3 in this position are surrounded on three sides. However, given that the permeable bricks 3 often need to be cut on-site at this position, and the cutting accuracy is limited, there are no strict requirements for the laying gaps during actual laying.

[0028] Please refer to Figure 1 and Figure 2 To achieve the displacement of the limiting plate II 202, a driving component 4 is configured below each limiting plate II 202. The driving component 4 is housed inside the mounting box 5 and is movably connected to the mounting box 5. Through the action of the driving component 4, the distance between the limiting plate II 202 and the corresponding limiting plate I 201 can be adjusted.

[0029] It should be pointed out that, as Figure 1 and Figure 3 As shown, each limiting plate II202 has corresponding clamping plates at its upper and lower ends, and these clamping plates are fixedly connected to the mounting box 5. The limiting effect between the clamping plates ensures the stable cooperation between the limiting plate II202 and the sliding connection mechanism.

[0030] In addition, such as Figure 1 and Figure 3 As shown, a corresponding limiting rod is also configured between the two clamping plates in the same vertical plane. The limiting rod and the clamping plate are detachably fixedly connected. Through the function of the limiting rod, the gap size between the two clamping plates is enhanced, preventing the clamping plates from deforming during long-term use due to the characteristics of thin plate parts, thus losing their clamping ability to limit plate II 202. At the same time, the presence of the limiting rod can also work in conjunction with the clamping plates to achieve complete positional constraint on limit plate II 202, ensuring that limit plate II 202 can only slide linearly in a single direction within the mounting box 5.

[0031] For details, see Figure 2 and Figure 4 The drive assembly includes a follower rod 402, which is rotatably connected to the mounting box 5. A follower gear 401 is connected to the outer side of the follower rod 402 via a key.

[0032] In addition, such as Figure 2 As shown, the limiting plate II 202 has corresponding teeth inside the mounting box 5 at the position corresponding to the follower gear 401. The meshing transmission between the teeth and the follower gear 401 allows the position of the limiting plate II 202 to be adjusted synchronously when the follower gear 401 rotates.

[0033] like Figure 3 , Figure 4As shown, a synchronizing member 6 is arranged between the two driving members 4, and the synchronizing member 6 is composed of a bevel gear set 601. In addition, the two follower rods 402 are connected to each other by means of the meshing transmission of the bevel gears.

[0034] Correspondingly, the outer side of one of the follower rods 402 is connected to the driven gear 602 via a key. The drive of the driven gear 602 can drive the follower rod 402, and with the help of the synchronous action of the bevel gear set 601, the two limit plates II 202 move synchronously.

[0035] Furthermore, in order to improve operating efficiency and simplify the operating process, this device is designed with a meshing transmission connection between the driven gear 602 and the drive gear 7, wherein the drive gear 7 is rotatably connected to the mounting box 5.

[0036] Furthermore, the drive gear 7 is meshed with the rack 8 for transmission, the rack 8 is slidably connected to the lifting rod 1, and a pull ring 9 is fixedly connected to the upper end of the rack 8. The upper end of the rack 8 is restricted from protruding from the lifting rod 1, and the lower end contacts the permeable brick 3. When the operator presses the rack 8, the position of the limiting plate II 202 is adjusted accordingly, contacting the permeable brick 3, preventing the permeable brick 3 and the limiting plate II from moving downwards simultaneously.

[0037] Furthermore, this device ensures that the transmission ratio between the drive gear 7 and the driven gear 602 is not the same. This design adjusts the ratio between the movement distance of the rack 8 and the movement distance of the limit plate II 202 to meet actual usage requirements.

[0038] Furthermore, such as Figure 5 As shown, this device specifies that the vertical projection of the contact portion between each limiting plate 2 and the permeable brick 3 is trapezoidal, and the upper width of the contact portion between the limiting plate 2 and the permeable brick 3 is smaller than the lower width. This design accelerates the separation of the limiting plate 2 and the permeable brick 3, prevents the limiting plate Ⅰ201 from damaging the position of the permeable brick 3 when it rises, and ensures the stability of the gap between adjacent permeable bricks 3.

[0039] In the actual application of this utility model, the positioning steps of the device include:

[0040] The operator moves the four limiting plates 2 (including two fixed limiting plates I 201 and two sliding limiting plates II 202) at the bottom of the installation box 5 to the outside of the permeable brick 3 to be laid, ensuring that each limiting plate 2 corresponds to one side of the permeable brick 3.

[0041] During the adjustment of the limiting plate 2, the sliding limiting plate II 202 is controlled by the drive component at the lower end of the lifting rod 1 to reduce the distance between the limiting plate I 201 and II, so that the inverted L-shaped openings of all the limiting plates 2 clamp the permeable brick 3 (using clamping force and frictional resistance to fix the brick body).

[0042] During the laying and gap control stage, while maintaining the clamped state, the permeable brick 3 is laid to the target position. At this time, the limiting plate I201 is embedded in the adjacent brick joint, and its thickness (e.g., 10mm) directly determines the laying gap;

[0043] During the operation of the separation device, the operator slides the limiting plate II 202 outward to separate it from the permeable brick cluster 3. At this time, the limiting plate I 201 remains in the brick joint to maintain the gap, while the limiting plate II 202 separates quickly through the trapezoidal inclined surface design (narrower at the top and wider at the bottom), avoiding disturbance to the brick position when the lifting device is used;

[0044] The operation details of the drive component include the gear transmission mechanism: when the rack 8 is pressed down (its lower end is in close contact with the permeable brick 3), the drive gear 7 rotates accordingly, which in turn drives the driven gear 602. Through the synergistic effect of the bevel gear set 601, the two follower rods 402 achieve synchronous movement. Finally, the follower gear 401 meshes with the teeth of the limiting plate II 202, causing the limiting plate II 202 to slide smoothly.

[0045] In terms of transmission ratio optimization, the transmission ratio between the drive gear 7 and the driven gear 602 is not equal to 1, so as to ensure that the small stroke of the rack 8 corresponds to the large displacement of the limit plate II 202 and adapts to the actual paving requirements.

[0046] The operation process of the recycling device is as follows: Pull the ring 9 upwards, and the rack 8 will reset accordingly. At the same time, under the guidance of the clamping plate, the limiting plate II 202 will smoothly retract to the initial position, marking the successful completion of a single laying cycle.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
