Description

Technical Field

[0001] This utility model relates to the field of epoxy asphalt concrete road construction technology, and in particular to an anti-dead material pushing device for epoxy asphalt concrete pavers. Background Technology

[0002] An epoxy asphalt concrete paver is a specialized piece of equipment for paving epoxy asphalt concrete. Its main working principle involves conveying the mixture to a mixing cage via a conveyor belt, where a auger spreader then evenly distributes the concrete. The screed of the paver typically has a mixing cage on its side for temporarily storing and conveying the mixture, ensuring uniform concrete paving and thus guaranteeing the construction quality of bridge decks or road surfaces.

[0003] However, in actual construction, the conveyor belt and auger often cause residual mixture in the mixing cage on the side of the screed during the feeding process. Over time, this mixture gradually accumulates. Epoxy asphalt concrete differs from traditional hot-mix asphalt concrete in that it has a curing reaction characteristic and a shorter allowable residence time. Once this time is exceeded, the accumulated mixture will form dead material. This dead material is not only difficult to clean, but may also be carried into the bridge deck during paving, affecting the pavement quality and even causing local structural defects in the bridge deck.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 5As shown: A material-pushing device for preventing dead material in an epoxy asphalt concrete paver, comprising: a pusher plate 1, a rotating assembly 2, and a pusher rod 3;

[0032] The pusher plate 1 is located inside the stirring cage 01 and is attached to the side plate 021 of the ironing plate 02 on the side near the spiral feeder 03;

[0033] The rotating component 2 is located on the top of the pusher plate 1 and hinges the top of the pusher plate 1 to the side plate 021;

[0034] One end of the push rod 3 is connected to the push plate 1, and the other end extends out of the outside of the stirring cage 01. The rotation of the push rod 3 drives the push plate 1 to rotate along the rotating assembly 2, thereby pushing the mixed material 04 accumulated on the side plate 021 and the platform 022 to the spiral distributor 03.

[0035] The anti-stagnant material pushing device is located inside the stirring cage 01 on the side of the ironing plate 02, such as... Figures 2 to 3 As shown, when in use, the push rod 3 extending out of the agitator 01 is turned so that the push rod 3 drives the push plate 1 to rotate along the rotating assembly 2, thereby pushing the accumulated mixture 04 on the platform 022 between the side plate 021 of the ironing plate 02 and the agitator 01 into the spiral feeder 03, thus preventing the generation of dead material.

[0036] The material pushing device for epoxy resin asphalt concrete pavers provided by this utility model has the advantages of simple structure and convenient operation compared with the prior art. It reduces the generation of dead material in the mixing cage 01 of the epoxy resin asphalt concrete paver, thereby avoiding the impact of dead material on the quality of steel bridge deck paving and significantly reducing quality defects in steel bridge deck paving.

[0037] It should be noted that before the installation of the anti-dead material pushing device, the mixed material 04 accumulated on the side plate 021 platform 022 was usually shoveled off by on-site construction personnel with tools after a period of time, which was time-consuming and laborious. This device can achieve the pushing function through the simple operation of the pushing plate 1, reducing the need for manual removal of dead material, thereby reducing labor costs and labor intensity.

[0038] Specifically, the opening and closing frequency of the pusher plate 1 can be set according to the specific characteristics of the mixture 04. In this embodiment, epoxy asphalt concrete is different from traditional hot-mix asphalt concrete and has curing reaction characteristics. Its allowable residence time is relatively short, generally about two hours for curing. The operator can move the pusher rod 3 to drive the pusher plate 1 every hour.

[0039] In this embodiment, multiple pusher plates 1 are arranged sequentially along one side of the ironing plate 02. In this embodiment, the pusher plate 1 can be a 50mm*100mm rectangular steel plate with a smooth and flat surface. In actual installation cases, it is tightly fitted to the side of the ironing plate 02, and its lower edge is tightly fitted to the platform 022 of the ironing plate 02.

[0040] As a preferred embodiment of the above, refer to Figure 4 The rotating component 2 is a hinge 21. One end of the hinge 21 is fixedly connected to the side plate 021, and the other end is fixedly connected to the top of the pusher plate 1. Specifically, the hinge 21 has a compact structure, is easy to manufacture and install, and other rotating structures can also be used, all within the scope of protection of this application. The pivot inside the hinge 21 provides a rotation fulcrum, ensuring that the pusher plate 1 can rotate smoothly during operation, avoiding shaking or obstruction, and improving the reliability of the device.

[0041] Among them, reference Figure 2 , Figure 3 It also includes a limiting rod 4 set on the vertical push rod 3. When the push rod 3 is turned, the end of the limiting rod 4 fits against the outer wall of the ironing plate 02 to limit it. Specifically, the setting of the limiting rod 4 ensures that the push rod 3 will not exceed the set angle during rotation, avoid damage to the rotating component 2 due to loss of control during operation, and increase the stability and service life of the device.

[0042] One specific implementation method for connecting the push rod 3 and the push plate 1 is as follows: the push rod 3 and the push plate 1 are fixedly arranged, as shown in the reference. Figure 4 In this embodiment, the push rod 3 and the push plate 1 can be fixed by welding, so that the push rod 3 and the push plate 1 form a rigid integrated structure. Welding fixation reduces the number of connecting parts and avoids bolt loosening or wear of hinge parts due to long-term use, thereby reducing maintenance costs.

[0043] Another specific implementation of the connection between the push rod 3 and the push plate 1 is that the push rod 3 and the push plate 1 are detachably connected.

[0044] like Figure 5As shown, a specific embodiment of the detachable arrangement between the push rod 3 and the push plate 1 is as follows: a cylindrical structure 11 is provided on the push plate 1, and a protrusion 31 is provided at one end of the push rod 3. The push rod 3 is inserted into the cylindrical structure 11, and the protrusion 31 is used to limit the insertion depth of the push rod 3, thereby preventing the push rod 3 from exceeding the predetermined position and ensuring the stable movement of the push plate 1. In this way, the cylindrical structure 11 and the push rod 3 can be fitted with a clearance. When it is necessary to push the push plate 1 to rotate, the operator inserts the push rod 3 and turns the push rod 3 to drive the push plate 1 to rotate along the rotating component 2, pushing down the accumulated material. After the push is completed, the push rod 3 can be easily pulled out and moved to another push plate 1 for use, which increases the applicability of the push rod 3, reduces the number of push rods required, and reduces costs.

[0045] In this embodiment, in order to reduce costs, the protrusion 31 can be a nut welded to the push rod 3, or a sheet-like or strip-like structure welded to the push rod 3, all of which are within the scope of protection of this application.

[0046] Another specific implementation method for the detachable arrangement between the push rod 3 and the push plate 1 is as follows: The push plate 1 is provided with a cylindrical structure 11, the cylindrical structure 11 is provided with an internal thread, and one end of the push rod 3 is provided with an external thread that mates with the internal thread. By rotating the push rod 3, the push rod 3 can move along the axial direction of the cylindrical structure 11, thereby realizing the fixed connection between the push rod 3 and the push plate 1. The threaded connection makes the push rod 3 and the push plate 1 highly detachable, which facilitates maintenance, cleaning and replacement and improves the adaptability of the equipment.

[0047] One specific implementation of the push rod 3 control method is as follows: the push rod 3 is manually controlled. Specifically, to rotate the push rod 3, the operator can stand on top of the ironing plate 02 at regular intervals and manually rotate the push rod. The manual control design of the push rod 3 simplifies the operation of the device, eliminating the need for additional electric or hydraulic systems and avoiding complex mechanical devices, making operation more direct and convenient. The operator only needs to manually rotate the push rod 3 to achieve the pushing action, reducing the complexity of the equipment and maintenance costs.

[0048] Another specific implementation method for controlling the push rod 3 is: the push rod 3 adopts automatic control.

[0049] As a preferred embodiment of the above embodiment, the top of the screed plate 02 is provided with a telescopic mechanism (not shown). The extended end of the telescopic mechanism is connected to the operating end of the pusher rod 3, and the control system of the telescopic mechanism is connected to the operating system in the paver cab, so that the operator can remotely control the telescopic mechanism and thus control the movement of the pusher plate 1. This remote operation improves work efficiency and avoids the operator from performing heavy physical labor on site.

[0050] Specifically, the telescopic mechanism can be a hydraulic cylinder, a pneumatic cylinder, or other mechanical telescopic structure, all of which are within the scope of protection of this application.

[0051] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
