Description

Technical Field

[0001] The invention relates to equipment for concrete paving, and in particular to an integrated machine for spraying, paving and spreading concrete on a steel bridge deck. Background Art

[0002] With the rapid development of modern transportation infrastructure, steel bridges have been widely used in various engineering constructions due to their excellent mechanical properties and high construction efficiency. However, in the construction and maintenance of bridges, the bridge deck treatment process has always been one of the key factors affecting the quality, durability and safety of the project. Traditional bridge deck treatment methods usually include multiple steps such as scraping, paving and spreading. These processes are not only time-consuming and labor-intensive, but also require a variety of equipment to work together. In addition, due to the large influence of human factors, the final construction quality is uneven and it is difficult to ensure consistency. In the face of complex and changing working conditions, traditional mechanical equipment often seems to be unable to cope with it and it is difficult to meet the needs of modern and efficient construction. Therefore, exploring more advanced and adaptable bridge deck treatment technology has become one of the current problems that need to be solved urgently. This can not only improve construction efficiency and reduce the investment of manpower and material resources, but also significantly improve the overall quality and service life of the bridge, providing a safer and more reliable guarantee for transportation.

[0003] For example, the "Steel Bridge Deck Prefabrication Paving Equipment" disclosed in the Chinese patent literature, with the publication number CN109306649B, includes a walking frame located on the steel bridge deck, a paving mechanism for paving the steel bridge deck concrete layer is installed on the walking frame, and a mobile silo for providing concrete to the paving mechanism is also provided on the walking frame. The disadvantage of this patent is that, as an existing conventional paver, this patent can only realize the paving function, and has a single function, resulting in more manpower consumption in multiple steps of steel bridge deck processing, and it is difficult to ensure the consistency between different steps. Summary of the invention

[0004] The present invention aims to overcome the problem that the paver in the prior art has a single function, which leads to more manpower consumption in multiple steps of steel bridge deck processing and difficulty in ensuring consistency between different steps. An all-in-one machine for spraying, paving and spreading steel bridge deck is provided, which can simultaneously realize the functions of spraying, paving and spreading, greatly saving manpower and ensuring consistency between different steps of bridge deck processing.

[0009] Preferably, the present application further comprises a concrete conveyor belt, wherein the end of the concrete conveyor belt is located above the spiral distributor.

[0010] Preferably, the paving thickness adjustment structure also includes a flatness adjustment structure, and the flatness adjustment structure includes a leveling cylinder for controlling the rotation of the traction boom in the pitch direction.

[0011] Preferably, a traction arm is installed on the frame, and the paving thickness adjustment structure includes a smoothing plate and a telescopic structure, the upper end of the telescopic structure is fixedly installed on the traction arm, and the lower end of the telescopic structure is connected to the smoothing plate.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiment 1, as Figure 1-6As shown, it includes walking tracks 1, crushing material conveyor belt 2, concrete conveyor belt 3, crushing material hopper 4, cab 5, engine and fuel tank 6, frame 7, spreading structure 8, ironing structure 9, material dividing and paving structure, traction structure 11, gluing structure 12, and glue box 13.

[0028] The walking crawler 1 is arranged on both sides of the frame 7 to provide stable support for the paver during operation, ensure uniform paving, adapt to different terrains, and improve construction efficiency.

[0029] There are two groups of crushed material conveyor belts 2, one on each side of the paver. The front end is close to the bottom of the crushed material hopper 4, while the rear end is connected to the top of the spreading structure 8, which is responsible for lifting the crushed material from the bottom to the top. During the working process, the crushed material conveyor belt 2 effectively transports the crushed material in the crushed material hopper 4 to the spreading structure 8, ensuring that the material can be smoothly transferred and used, thereby ensuring the continuity and efficiency of the entire paving process.

[0030] The concrete conveyor belt 3 is located in the front center of the paver to ensure that the concrete from the concrete transport truck can be accurately received during the working process and smoothly transported to the paving device at the rear of the paver.

[0031] There are two sets of crusher hoppers 4, which are installed on both sides of the front end of the paver. The capacity of the crusher hopper 4 is sufficient to support the continuous paving operation of a concrete transport truck. When the concrete in the current concrete transport truck is exhausted, it can switch to another ready concrete transport truck to continue the operation. During the process of alternating connection between the two vehicles, the crusher hopper 4 will simultaneously carry out the filling work to ensure a seamless connection of the construction process.

[0032] The cab 5 is located above the paver, providing the driver with a wide field of vision, allowing the driver to clearly observe the construction situation ahead and the changes in the surrounding environment, so as to make more accurate operational judgments. The engine and fuel tank 6 are placed behind the cab 5 to provide continuous and stable power support for the entire vehicle.

[0033] The material distribution and paving structure includes a spiral distributor 10, and the ironing structure 9 includes a paving thickness adjustment mechanism. The material distribution and paving structure is located below the end of the concrete conveyor belt 3, and the ironing structure 9 is installed on the traction arm 1104. It is designed as a detachable structure to ensure the convenience and flexibility of the paver when it is transferred. During the working process, the concrete from the concrete conveyor belt 3 is evenly distributed along the width direction through the spiral distributor 10, and the concrete paving operation is realized.

[0034] The paving thickness adjustment mechanism is hung on the traction arm 1104 through the square tube 901. The paving thickness adjustment mechanism includes a telescopic structure 902, a smoothing plate 903, a vibrator 904, a hinge device, a front baffle 906, and two side plates 907. The vibrator 904 is fixedly mounted on the smoothing plate 903. The smoothing plate 903 is connected to the upper part of the smoothing structure 9 through the hinge hole and the telescopic structure 902. The height of the smoothing plate 903 is adjusted by the extension and retraction of the telescopic structure 902, thereby achieving coarse adjustment of the paving thickness.

[0035] The traction structure 11 includes a traction boom 1104, which is hoisted on the frame 7 by a leveling cylinder 1101 and a traction cylinder 1103, wherein the traction boom 1104 is connected to the traction arm 1102 by bolts, the front end of the traction arm 1102 is connected to the leveling cylinder 1101 by a hinge, and the guide seat 1105 is fixed on both sides of the crawler track. During operation, the leveling cylinder 1101 realizes the rotation of the traction boom 1104 around the hinge point 905 between the traction cylinder 1103 and the traction boom 1104 through the extension and retraction of the plunger, thereby realizing the adjustment of the working elevation angle of the ironing structure 9, thereby realizing the adjustment of the flatness of the paving operation.

[0036] Furthermore, a detection port is provided at the front and rear of the screed plate 903, and a photoelectric sensor is installed at the detection port. The photoelectric sensor determines the flatness and height of the current ground by detecting the distance to the ground, thereby guiding the adjustment of the paving thickness adjustment mechanism and the paving working elevation angle.

[0037] The scraper is located in front of the ironing structure 9 and the material distribution paving structure. In the working process, the rubber material spread in the rubber material box 13 is evenly distributed along the width direction by the scraper, thereby ensuring the quality of the subsequent concrete paving operation.

[0038] The rubber box 13 is located at the rear side of the walking track 1 and the front side of the scraper. The rubber stored in it is enough to support the continuous paving operation of a concrete transport vehicle. The rubber replenishment process can be completed during the alternating connection of two concrete transport vehicles, thereby ensuring a seamless connection of the entire construction process. In addition, the rubber spreading device is installed at the rear side of the walking track 1, which can effectively prevent the walking track 1 from adhering to the rubber, thereby ensuring that the quality of the paving operation is not disturbed.

[0039] The spreading structure 8 is installed below the end of the crushed material conveyor belt 2. It is a detachable structure, which ensures the convenience and flexibility of the paver when it is transferred. During the working process, the spreading structure 802 installed inside the spreading bin 801 can ensure that the crushed materials in the spreading bin 801 are evenly distributed along the entire working width, effectively avoiding the problem of local missing during spreading. To further refine the control, the adjustment of the material gate 804 can adjust the amount of surface sand passing through to meet different construction needs. The opening and closing of the opening and closing material gate 805 is controlled by the material gate cylinder 803. This automated design not only improves the convenience of operation, but also ensures the immediacy and accuracy of the surface sand spreading. Finally, with the rotation of the spreading roller 806, the surface sand is evenly spread on the ground, completing the process of evenly spreading the surface sand.

[0040] In actual operation, firstly, the surface sand or crushed stone is added into the crushing hopper 4, and at the same time, it is ensured that the concrete delivery vehicle and the paver are properly connected and ready. After the preparation is completed, the equipment is started to allow the concrete delivery vehicle and the paver to move forward synchronously. Next, the rubber is evenly spread on the ground through the rubber box 13, and the uniform distribution of the rubber is achieved through the scraper.

[0041] Subsequently, the concrete is transported to the ironing structure 9 through the concrete conveyor belt 3, and the spiral distributor 10 evenly distributes the concrete along the width direction, and the pavement paving operation is completed through the paving thickness adjustment structure. Finally, the surface sand in the crushing hopper 4 is transported to the spreading structure 8 through the crushing conveyor belt 2. The spreading structure 802 installed inside the spreading bin 801 ensures that the crushed materials in the spreading bin 801 are evenly distributed along the entire working width. The adjusting gate 804 can adjust the amount of surface sand passing through, and the opening and closing of the opening and closing gate 805 is controlled by the hydraulic cylinder to complete the spreading work. This complete set of operating procedures enables the equipment to efficiently and accurately complete the tasks of scraping glue, concrete paving and surface sand spreading.

The first material dividing screen 807 is provided with sieve holes on the part located in the first spreading bin 808. The broken materials passing through the spreading structure 802 first fall onto the first material dividing screen 807. At this time, some fine broken materials pass through the first material dividing screen 807 and fall into the first spreading bin 808, while the remaining larger broken materials fall into the second spreading bin 809 along the slope of the material dividing screen. In addition, a blowing structure is installed in the spreading roller 806, and a plurality of air holes are provided on the spreading roller 806. Air is blown outward through the air holes to blow away the broken materials accumulated on the spreading roller 806, thereby avoiding the problem of "edge accumulation" caused by the traditional spreading structure 8.

Finally, the surface sand in the crushing hopper 4 is transported to the spreading structure 8 through the crushing conveyor belt 2. The spreading and spreading structure 802 installed inside the spreading bin 801 ensures that the crushed materials in the spreading bin 801 are evenly distributed along the entire working width. The adjusting material gate 804 can adjust the amount of surface sand passing through, and the opening and closing of the opening and closing material gate 805 is controlled by the hydraulic cylinder to complete the spreading work. This complete set of operating procedures enables the equipment to efficiently and accurately complete the tasks of scraping glue, concrete paving and surface sand spreading.

[0075] Embodiment 4, as Figure 1-6 8, including walking tracks 1, crushing material conveyor belt 2, concrete conveyor belt 3, crushing material hopper 4, cab 5, engine and fuel tank 6, frame 7, spreading structure 8, ironing structure 9, material spreading structure, traction structure 11, gluing structure 12, and glue box 13.

[0076] The walking crawler 1 is arranged on both sides of the frame 7 to provide stable support for the paver during operation, ensure uniform paving, adapt to different terrains, and improve construction efficiency.

[0077] There are two groups of crushed material conveyor belts 2, one on each side of the paver. The front end is close to the bottom of the crushed material hopper 4, while the rear end is connected to the top of the spreading structure 8, which is responsible for lifting the crushed material from the bottom to the top. During the working process, the crushed material conveyor belt 2 effectively transports the crushed material in the crushed material hopper 4 to the spreading structure 8, ensuring that the material can be smoothly transferred and used, thereby ensuring the continuity and efficiency of the entire paving process.

[0078] The concrete conveyor belt 3 is located in the front center of the paver to ensure that the concrete from the concrete transport truck can be accurately received during the working process and smoothly transported to the paving device at the rear of the paver.

[0079] There are two sets of crusher hoppers 4, which are installed on both sides of the front end of the paver. The capacity of the crusher hopper 4 is sufficient to support the continuous paving operation of a concrete transport truck. When the concrete in the current concrete transport truck is exhausted, it can switch to another ready concrete transport truck to continue the operation. During the process of alternating connection between the two vehicles, the crusher hopper 4 will simultaneously carry out the filling work to ensure a seamless connection of the construction process.

[0080] The cab 5 is located above the paver, providing the driver with a wide field of vision, allowing the driver to clearly observe the construction situation ahead and the changes in the surrounding environment, so as to make more accurate operational judgments. The engine and fuel tank 6 are placed behind the cab 5 to provide continuous and stable power support for the entire vehicle.

[0081] The material distribution and paving structure includes a spiral distributor 10, and the ironing structure 9 includes a paving thickness adjustment mechanism. The material distribution and paving structure is located below the end of the concrete conveyor belt 3, and the ironing structure 9 is installed on the traction arm 1104. It is designed as a detachable structure to ensure the convenience and flexibility of the paver when it is transferred. During the working process, the concrete from the concrete conveyor belt 3 is evenly distributed along the width direction through the spiral distributor 10, and the concrete paving operation is realized.

[0082] The paving thickness adjustment mechanism is hung on the traction arm 1104 through the square tube 901. The paving thickness adjustment mechanism includes a telescopic structure 902, a smoothing plate 903, a vibrator 904, a hinge device, a front baffle 906, and two side plates 907. The vibrator 904 is fixedly mounted on the smoothing plate 903. The smoothing plate 903 is connected to the upper part of the smoothing structure 9 through the hinge hole and the telescopic structure 902. The height of the smoothing plate 903 is adjusted by the extension and retraction of the telescopic structure 902, thereby achieving coarse adjustment of the paving thickness.

[0083] The traction structure 11 includes a traction boom 1104, which is hoisted on the frame 7 by a leveling cylinder 1101 and a traction cylinder 1103, wherein the traction boom 1104 is connected to the traction arm 1102 by bolts, the front end of the traction arm 1102 is connected to the leveling cylinder 1101 by a hinge, and the guide seat 1105 is fixed on both sides of the crawler track. During operation, the leveling cylinder 1101 realizes the rotation of the traction boom 1104 around the hinge point 905 between the traction cylinder 1103 and the traction boom 1104 through the extension and retraction of the plunger, thereby realizing the adjustment of the working elevation angle of the ironing structure 9, thereby realizing the adjustment of the flatness of the paving operation.

[0084] Furthermore, a detection port is provided at the front and rear of the screed plate 903, and a photoelectric sensor is installed at the detection port. The photoelectric sensor determines the flatness and height of the current ground by detecting the distance to the ground, thereby guiding the adjustment of the paving thickness adjustment mechanism and the paving working elevation angle.

[0085] The scraper is located in front of the screed structure 9. During operation, the rubber material spread in the rubber material box 13 is evenly distributed along the width direction by the scraper, thereby ensuring the quality of subsequent concrete paving operations.

[0086] The rubber box 13 is located at the rear side of the walking track 1 and the front side of the scraper. The rubber stored in it is enough to support the continuous paving operation of a concrete transport vehicle. The rubber replenishment process can be completed during the alternating connection of two concrete transport vehicles, thereby ensuring a seamless connection of the entire construction process. In addition, the rubber spreading device is installed at the rear side of the walking track 1, which can effectively prevent the walking track 1 from adhering to the rubber, thereby ensuring that the quality of the paving operation is not disturbed.

[0087] The spreading structure 8 is installed below the end of the crushed material conveyor belt 2. It is a detachable structure, which ensures the convenience and flexibility of the paver when it is transferred. During the working process, the spreading structure 802 installed inside the spreading bin 801 can ensure that the crushed materials in the spreading bin 801 are evenly distributed along the entire working width, effectively avoiding the problem of local missing during spreading. To further refine the control, the adjustment of the material gate 804 can adjust the amount of surface sand passing through to meet different construction needs. The opening and closing of the opening and closing material gate 805 is controlled by the material gate cylinder 803. This automated design not only improves the convenience of operation, but also ensures the immediacy and accuracy of the surface sand spreading. Finally, with the rotation of the spreading roller 806, the surface sand is evenly spread on the ground, completing the process of evenly spreading the surface sand. In addition, a blowing structure is installed in the spreading roller 806. The spreading roller 806 is provided with a plurality of air holes. Air is blown outward through the air holes to blow away the debris accumulated on the spreading roller 806, thereby avoiding the problem of "edge accumulation" caused by the traditional spreading structure 8.

[0088] Furthermore, a spreading and screening channel 810 is provided below the spreading roller 806. The spreading and screening channel 810 is inclined downward in the direction from front to back when the device is moving. The screening channel 810 is provided with a plurality of screening areas in sequence from front to back. The plurality of screening areas are provided with screen holes of different sizes, and the screen hole diameters of the screening areas increase in sequence from front to back. When the crushed materials fall onto the screening channel 810, the smaller crushed materials fall from the front side, and the larger crushed materials fall from the back side, so that during the movement of the device, at the same position, the larger crushed materials are laid first, and then the smaller crushed materials are laid, so that the crushed materials are laid with better effect and higher density.

[0089] In actual operation, firstly, the surface sand or crushed stone is added into the crushing hopper 4, and at the same time, it is ensured that the concrete delivery vehicle and the paver are properly connected and ready. After the preparation is completed, the equipment is started to allow the concrete delivery vehicle and the paver to move forward synchronously. Next, the rubber is evenly spread on the ground through the rubber box 13, and the uniform distribution of the rubber is achieved through the scraper.

[0090] Subsequently, the concrete is transported to the material distribution and paving structure through the concrete conveyor belt 3, and the spiral distributor 10 is used to evenly distribute the concrete along the width direction, and the paving thickness adjustment structure is used to complete the pavement paving operation. Finally, the surface sand in the crushing hopper 4 is transported to the spreading structure 8 through the crushing conveyor belt 2. The spreading and spreading structure 802 installed inside the spreading bin 801 ensures that the crushed materials in the spreading bin 801 are evenly distributed along the entire working width. The adjusting material gate 804 can adjust the amount of surface sand passing through, and the opening and closing of the opening and closing material gate 805 is controlled by the hydraulic cylinder to complete the spreading work. This complete set of operating procedures enables the equipment to efficiently and accurately complete the tasks of scraping glue, concrete paving and surface sand spreading.
