Description

Technical Field

[0001] This utility model relates to an intelligent concrete finishing machine for high-speed railway bridge decks, belonging to the technical field of road and bridge construction equipment. Background Technology

[0002] Waterproofing is required on high-speed railway bridge decks, one aspect of which involves laying waterproof concrete. After the waterproof concrete has set, a finishing process is needed to improve its smoothness. Because the waterproof concrete on high-speed railway bridge decks is located between two track slabs, the space is limited and unsuitable for large equipment. Currently, traditional finishing work on high-speed railway waterproof concrete largely relies on manual labor. Manual finishing is not only inefficient and labor-intensive, but the quality is also greatly affected by the skill level and working condition of the workers, making it difficult to guarantee uniformity and consistency.

[0003] In addition, to ensure timely drainage of rainwater, drainage holes need to be installed at regular intervals along the longitudinal direction of the road. Furthermore, undulating slopes are typically incorporated to facilitate rainwater flow. The drainage holes are located at the troughs between the two peaks of the undulating road surface. The slope of this slope does not need to be too steep. Existing equipment is not capable of effectively smoothing such undulating surfaces.

[0004] Although some concrete finishing machinery has emerged, these devices are generally large and complex in structure, making them difficult to operate in confined areas such as retaining walls on high-speed railway bridge decks. This fails to meet the demands of the unique construction environment in high-speed railway construction. Furthermore, due to the special structural characteristics of the areas surrounding the drainage holes on high-speed railway bridge decks, existing finishing equipment struggles to perform effective mechanized finishing in these areas, still requiring manual secondary processing, which increases construction costs and time.

[0005] The purpose of this invention is to provide an intelligent concrete finishing machine for high-speed railway bridge decks to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A smart finishing machine for high-speed railway bridge deck concrete includes a main support frame with wheels at both ends, a main finishing mechanism mounted on the main support frame, and an auxiliary finishing mechanism for finishing the surface around the water collection holes. The main finishing mechanism includes a finishing frame, a smoothing finishing component suspended on the finishing frame, and a lifting component for adjusting the height of the finishing frame. The auxiliary finishing mechanism includes a water collection hole finishing component that can move up and down.

[0008] A further improvement to the technical solution of this utility model is that: the troweling and finishing assembly includes a troweling plate driven by a motor; the troweling and finishing assembly is installed on the troweling frame; the troweling frame is installed on the finishing frame by means of a hanging rod, and the troweling frame can be adjusted to adapt to the undulating surface troweling by adjusting the angle relative to the horizontal plane.

[0009] A further improvement to the technical solution of this utility model is that the auxiliary dough-collecting mechanism can move laterally on the track of the main support.

[0010] A further improvement to the technical solution of this utility model is as follows: the auxiliary dough-collecting mechanism includes a mounting base, an auxiliary dough-collecting lifting component fixed on the mounting base, and a water-collecting hole dough-collecting component; the mounting base is provided with movable wheels that can be locked onto the track; the auxiliary dough-collecting lifting component includes a screw jack and a set of lifting cylinder and fixed cylinder; the screw jack drives the lifting cylinder to slide and rise within the fixed cylinder; the water-collecting hole dough-collecting component is fixedly installed at the lower end of the lifting cylinder.

[0011] A further improvement to the technical solution of this utility model is that the water collection hole finishing component consists of several oblique polishing plates with a rotation trajectory of a conical surface; the oblique polishing plates are fixed on the rotating shaft and are evenly distributed around the rotating shaft.

[0012] A further improvement to the technical solution of this utility model is that the water collection hole finishing assembly includes a frustum-shaped polishing disc; the polishing disc is fixed on a rotating shaft.

[0013] A further improvement to the technical solution of this utility model is that the smoothing and finishing assembly is an ironing plate driven by a vibrating motor; the two ends of the ironing plate are hinged to the finishing frame.

[0014] A further improvement to the technical solution of this utility model is that anti-collision wheels are provided on the outer sides of both ends of the main support.

[0015] A further improvement to the technical solution of this utility model is that a cutter for processing expansion joints is provided on one side of the main support; the cutter is raised and lowered under the drive of the lifting mechanism.

[0016] A further improvement to the technical solution of this utility model is that the cutter has a triangular cross-section; or a rectangular cross-section; or a serrated structure; and a vibrator is provided on the cutter.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this utility model are as follows:

[0018] This utility model is an intelligent finishing machine for waterproof concrete in high-speed railways. It adopts a small main support frame and achieves machine miniaturization through a compact structural layout. It can move along the retaining wall of the high-speed railway bridge deck and perform concrete finishing construction in narrow areas. Mechanized finishing of various areas is achieved through two finishing mechanisms.

[0019] This utility model's finishing machine is equipped with two sets of finishing structures. The front set uses a double longitudinal finishing device that moves along the length of the bridge deck to finish large areas of concrete surface. Through uniform pressure and high-frequency smoothing, surface air bubbles are fully removed, enhancing concrete density; promoting cement slurry to float and form a dense, hardened layer, significantly improving surface compressive strength and inhibiting cracking. The rear set is a single transverse finishing device that can move along the width of the bridge deck, specifically for finishing the area around drainage holes. It can precisely adjust the slope of the area around the conical drainage holes according to design requirements; solving the problem of complex slope connections that are difficult to handle manually, ensuring smooth drainage and no water accumulation. The two finishing mechanisms work together to achieve fully mechanized construction of waterproof concrete for high-speed railway bridge decks.

[0020] The main finishing mechanism of this invention can adaptably smooth concrete surfaces with a certain slight slope, realizing mechanized construction that replaces traditional manual labor.

[0021] This utility model's life-saving machine operates by mounting the entire machine on the concrete retaining walls on both sides of the bridge deck via a walking mechanism.

Detailed Implementation

[0032] 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.

[0033] 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.

[0034] This utility model relates to an intelligent concrete finishing machine for high-speed railway bridge decks, primarily used for finishing concrete surfaces in the narrow areas between track slabs on high-speed railway bridge decks. The machine features a compact and small structure, making it suitable for construction in specific locations on high-speed railway bridge decks. The equipment is designed based on the high-speed railway bridge deck structure, with retaining walls on both sides and a drainage slope in the middle.

[0035] like Figure 1 , Figure 2 As shown, the dough finishing machine mainly consists of a main support frame 1, a main dough finishing mechanism mounted on the main support frame 1, and an auxiliary dough finishing mechanism. Traveling wheels 2 are installed at both ends of the main support frame 1, and the traveling wheels 2 are driven by a drive mechanism formed by a traveling motor and a reducer. Preferably, the traveling wheels 2 are rubber wheels, enabling them to travel smoothly on the retaining walls of the high-speed railway bridge deck. The main dough finishing mechanism on the main support frame 1 is used to smooth and finish the main areas between the track slabs. The auxiliary dough finishing mechanism is used for mechanized dough finishing of the smaller, more specific areas around the drainage holes.

[0036] like Figure 6 , Figure 7As shown in the figure, the main finishing mechanism includes a finishing frame 3, a finishing assembly, and a lifting assembly 4. The finishing frame 3 provides support for the finishing assembly, and the lifting assembly 4 can adjust the height of the finishing frame 3 and the finishing assembly. The finishing assembly is installed on the finishing frame 3 by hoisting. The finishing assembly can not only finish flat surfaces, but also adapt to and finish sloped surfaces with a certain gradient or a gentle slope.

[0037] The auxiliary finishing mechanism is used for smoothing the area around the water collection point. It mainly consists of a template-like finishing component whose shape matches the shape of the water collection point, allowing for direct smoothing and finishing of the area. The auxiliary finishing mechanism includes a water collection point finishing component, which can move up and down. When finishing is needed at the water collection point, the component moves downwards. When the entire machine moves, the component moves upwards and is raised.

[0038] like Figure 3 , Figure 7 As shown, in specific implementation, the following method is preferred for setting up the troweling and finishing assembly. In this method, the troweling and finishing assembly directly uses components similar to those on the troweling machine. The troweling and finishing assembly includes a motor-driven troweling blade 5, the output shaft of which is connected to a troweling shaft, on which multiple troweling blades 5 are mounted. The troweling blades 5 are evenly distributed around the troweling shaft. The troweling and finishing assembly is mounted on the troweling frame 6; then the troweling frame 6 is installed using a lifting rod 7, which is used to suspend the troweling frame 6. The upper end of the lifting rod 7 is not fixed to the finishing frame 3, but is slidably mounted on the finishing frame 3. The lifting rod 7 can be moved and adjusted relative to the finishing frame 3, and a certain amount of clearance is provided between the sliding fit between the lifting rod 7 and the finishing frame 3. After the uppermost end of the lifting rod 7 passes through the finishing frame 3, a nut is fixedly installed as a stop to prevent the troweling and finishing assembly from falling. Because the trowel frame 6 is hoisted and installed, after the trowel plate 5 of the troweling and finishing component contacts the slope, it can adjust to the slope through its own weight. This allows the trowel frame 6, connected to the troweling and finishing component, to form a certain angle with the horizontal plane through its own adjustment, thus adapting to the undulating surface and troweling it. The undulating surface here is designed to allow rainwater to converge towards the drainage holes; the slope of the undulating surface is not too large, which can be achieved through the adjustment of the hanger 7. The gap between the hanger 21 and the finishing frame 19 can accommodate this adjustment. When the troweling and finishing component contacts the concrete surface, it stands vertically on the concrete surface by its own weight. The horizontal movement of the troweling and finishing component is achieved by the movement of the finishing frame 3. Before the finishing construction, the undulating contour of the bridge deck has already been formed. This machine is used to trowel and finish the already formed road surface, improving the surface smoothness.

[0039] The finishing machine is equipped with an auxiliary finishing mechanism to smooth and finish the area near the water collection holes. The water collection holes are circular with a conical circumference. Water collection holes are spaced at intervals along the longitudinal direction on the high-speed railway bridge deck. Ideally, the water collection holes should be aligned on the same longitudinal line. However, in actual construction, deviations may occur. Therefore, to better adapt the auxiliary finishing mechanism to the finishing work on the water collection holes, it is designed to move laterally along the track of the main support 1.

[0040] For example, 1. Figure 4 , Figure 5 As shown, a track is set on one side of the main support, and the auxiliary finishing mechanism is installed on the track. Specifically, the auxiliary finishing mechanism includes a mounting base 8, an auxiliary finishing lifting assembly fixed on the mounting base 8, and a water collection hole finishing assembly. The mounting base 8 is a base plate mechanism, the auxiliary finishing lifting assembly is set on the mounting base 8, and the water collection hole finishing assembly is set at the lower end of the auxiliary finishing lifting assembly.

[0041] The auxiliary dough-collecting mechanism of this dough-collecting machine can move laterally within a short range, allowing the mounting base to drive the auxiliary dough-collecting mechanism to move laterally. One implementation method uses a screw-driven transverse mechanism 16 as the driving force source. The screw-driven transverse mechanism 16 is essentially a screw jack, simply placed horizontally. The screw-driven transverse mechanism 16 is fixed to one side of the track on the main support 1, and its output shaft is connected to the mounting base 8 or the fixed cylinder 12, thus enabling the entire auxiliary dough-collecting mechanism to move laterally. This method allows for lateral movement within a short range, suitable for the lateral movement requirements of the auxiliary dough-collecting mechanism in this dough-collecting machine.

[0042] like Figure 4 , Figure 5 As shown, furthermore, multiple movable wheels 10 are provided on one side of the mounting base 8, which can be engaged with the track to realize the installation of the mounting base 8 on the track. The auxiliary lifting assembly mainly includes a screw jack 9 and a set of lifting cylinder 11 and fixed cylinder 12. The fixed cylinder 12 is directly fixedly mounted on the mounting base 8; the lifting cylinder 11 is fitted inside the fixed cylinder 12 and can slide and rise within the fixed cylinder 12. The lifting of the lifting cylinder 11 is driven by the screw jack 9. The screw jack 9 is located at the upper end of the fixed cylinder 12, and the output shaft of the screw jack 9 is fixedly connected downward to the lifting cylinder 11, thereby driving the lifting cylinder 11 to slide and rise.

[0043] A water collection hole finishing assembly is fixedly installed at the lower end of the lifting cylinder 11. The water collection hole finishing assembly also uses a finishing plate method, but the difference is that the finishing plate consists of multiple inclined finishing plates 5. These inclined finishing plates 5 are fixed on a rotating shaft, and are evenly distributed around the shaft. The rotation trajectory of the inclined finishing plates 5 is a conical surface, thus achieving one-time finishing of the water collection hole location. The inclined finishing plates 5 are inclined relative to the plane.

[0044] Alternatively, the water collection hole finishing component can be configured as a polishing disc, with the polishing disc fixed on the rotating shaft. The polishing disc, being an inverted frustum, can also achieve one-time shaping and polishing.

[0045] In another embodiment, the finishing assembly can be configured as an ironing board driven by a vibrating motor, using the ironing board method for finishing. The two ends of the ironing board are hinged to the finishing frame, relying on its own gravity to adapt to the sloping surface.

[0046] Regarding the selection of screeds and trowels, generally speaking, screeds are used before the initial setting of concrete, and trowels are used after the initial setting of concrete.

[0047] This intelligent dough-collecting machine travels along a retaining wall during operation. To ensure smooth movement and prevent collisions with the retaining wall, anti-collision wheels 14 are typically installed on the outer sides of both ends of the main support 1, with at least two anti-collision wheels 14 on each side.

[0048] The equipment also has the function of cutting expansion joints, which is achieved by installing a cutter 13. Specifically, a cutter 13 for processing expansion joints is set on the other side of the main support 1. The cutter 13 is installed on the main support 1 via a lifting mechanism, and is raised and lowered under the drive of the lifting mechanism. When cutting is required, the cutter 13 descends to cut the joint. Here, the lifting mechanism is usually a screw jack, which is used to drive the cutting 13 to rise and fall. Specifically... Figure 2 As shown.

[0049] Furthermore, the cutter 13 mainly has three structural forms. First, the cutter 13 has a triangular cross-section. Second, the cutter 13 has a rectangular cross-section. Third, the cutting edge of the cutter 13 has a serrated structure. In addition, to improve the cutting quality and prevent concrete from being carried out when the cutter 13 moves upward, a vibrator is usually installed on the cutter 13 to perform high-frequency, low-amplitude vibration during cutting. After the machine moves to the designated position, the cutter 13 is used to perform the cutting operation.

[0050] This dough-forming machine has a control system that adjusts the dough-forming process to ensure adaptation to undulating surfaces and precise construction of water collection holes.

[0051] This invention relates to an intelligent finishing machine for waterproof concrete on high-speed railways. Its compact design allows it to move along the retaining walls of high-speed railway bridge decks, enabling it to perform concrete finishing work in confined areas. After implementation, this equipment enables mechanized finishing of waterproof concrete on high-speed railway bridge decks, improving work efficiency and construction quality.

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.
