Abstract
Description
Technical Field
[0001] This utility model relates to a small intelligent slipform fabrication machine, belonging to the field of road and bridge construction technology. Background Technology
[0002] Slipform pavers, as a highly efficient and precise concrete construction equipment, are widely used in large-scale surface engineering projects such as roads and airport runways. Their core advantage lies in the continuous forming process using sliding formwork, integrating concrete paving, vibration, leveling, and surface treatment, significantly improving construction efficiency and quality. However, traditional slipform pavers are mostly designed for wide road surfaces, are bulky, and require ample construction space, making them unsuitable for the precise construction needs of special scenarios such as high-speed rail tracks and narrow urban areas.
[0003] High-speed rail tracks have extremely high requirements for flatness, durability, and geometric accuracy. Traditional construction methods rely on manual formwork and segmented pouring, which are inefficient and prone to joint errors. Slipform paving technology, through continuous molding without formwork, can significantly improve the construction speed of track slabs.
[0004] In narrow spaces such as high-speed rail tracks, tunnels, or urban underground utility tunnels, the size and mobility of traditional slipform pavers become bottlenecks. Utility Model Content

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", 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.
[0030] This utility model is a small intelligent slipform fabric laying machine, mainly used for construction of road surfaces in limited spaces and with relatively small widths, such as high-speed railway tracks. In the following description, the forward direction of the machine is considered as "forward".
[0031] like Figure 1 , Figure 2 As shown, the slipform paver mainly includes a traveling frame 1, a hopper 3, and a slipform plate. Traveling wheels 2 are installed at the outer ends of the traveling frame 1, and these wheels are driven by a drive mechanism consisting of a motor and a reducer, thus enabling the traveling frame 1 to move the entire machine. The hopper 3 and the slipform plate are both mounted on the traveling frame 1. The hopper 3 is used to hold and discharge materials. The slipform plate is used for slipforming the concrete surface.
[0032] If construction is carried out in a confined space, and there are barriers on both sides of the construction surface, anti-collision wheels 11 can usually be installed on the side of each walking frame 1. Usually, there are at least two anti-collision wheels 11 on the side of each walking frame 1. The anti-collision wheels 11 serve to prevent collisions and also have a certain guiding function.
[0033] The hopper 3 and the sliding formwork are installed on the traveling frame 1 via the lifting mechanism 4. The lifting mechanism 4 can adjust the height of the working surface, so that construction can be carried out according to the design height of the road surface, thereby obtaining a road surface that meets the design requirements.
[0034] like Figure 4 , Figure 5 As shown, a material distribution auger 5 is installed inside the hopper 3. The material distribution auger 5 is driven by a motor to rotate. During the rotation, the material distribution auger 5 can evenly distribute the material, thus achieving material distribution. Typically, when injecting concrete into the hopper 3, it is injected from one side; the material distribution auger 5 can transport the concrete from one side of the hopper 3 to the other side, achieving material distribution during the transportation process.
[0035] The slipform is set behind the discharge port of hopper 3. After the material is laid, the road surface can be directly slip-formed. The slipform performs slip forming, surface finishing and shaping of the road surface, and has the function of surface finishing and shaping.
[0036] In practical implementation, two sets of traveling frames 1 are typically arranged at intervals, and lifting mechanisms 4 are installed on these two sets of traveling frames 1. The hopper 3 and the sliding plate are positioned between the two sets of traveling frames 1. Furthermore, a lifting frame 6 is also installed. The lifting frame 6 is located between the two sets of traveling frames 1, with both ends of the lifting frame 6 connected to the lifting mechanism 4. The lower fixed end of the lifting mechanism 4 is then installed on the traveling frame 1, and the lifting frame 6 is mounted on the traveling frame 1 via the lifting mechanism 4. The hopper 3 and the sliding plate are placed on the lifting frame 6, and the lifting frame 6 drives the hopper 3 and the sliding plate to adjust their height.
[0037] The lifting mechanism 4 can be a direct electric screw jack or an electric push rod.
[0038] This slipform paver is usually equipped with an attached vibrator 7 fixed on the outer side of the hopper 3. During operation, the attached vibrator 7 vibrates the hopper 3 to prevent the material from sticking to the inner wall of the hopper 3.
[0039] The slipform plate of this slipform paver is used for slipforming the paved concrete pavement. Specifically, the slipform plate typically includes a transition slipform plate 8 and a main slipform plate 9. The main slipform plate 9 ultimately serves to fix the slipform shape. The transition slipform plate 8 connects the main slipform plate 9 and the hopper 3. As shown in the figure, the main slipform plate 9 is set horizontally. The transition slipform plate 8 is set at an angle, with one end being the higher side and the other end being the lower side. The higher side of the transition slipform plate 8 is connected to the outlet of the hopper 3, while the lower side of the transition slipform plate 8 is connected to the main slipform plate 9. The transition slipform plate 8 serves as a transition, allowing the pavement to gradually transition to the fixed height surface of the main slipform plate 9. This is beneficial to the quality of slipforming and also prevents material from accumulating at the front end of the main slipform plate 9. Specifically, as shown... Figure 3As shown.
[0040] An attached vibrator can also be installed on the slipform plate to vibrate and lift the slurry during slipforming, thereby improving the quality of slipforming.
[0041] In this technical solution, the main sliding template 9 serves as a template for slip molding. The main sliding template 9 and the transition sliding template 8 are made of high-strength board to ensure structural strength.
[0042] The present invention can also fix a flexible baffle plate 10 on the front side of the lower end discharge port of the hopper 3. The flexible baffle plate 10 installed here can prevent the material from flowing forward.
[0043] This utility model's slipform paver has a control system that automatically operates after paving parameters are input into the control system. Furthermore, it can be equipped with a wireless remote control for remote operation.
[0044] This utility model is a new type of small intelligent slipform machine, which is suitable for slipform construction of narrow and wide road surfaces such as high-speed railway tracks. It can realize rapid slipform construction of road surfaces, and is flexible and adaptable.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 claims.
