[0029] First embodiment

[0030] See also Figures 1 to 5 The present invention provides a bridge concrete pouring device with an automatic slag cleaning function, comprising a base 101, a support plate 102, a pouring head 103, a bottom plate 104, a first pushing cylinder 105, four side plates 106, a top sealing plate 107, a position controller 108 and a cleaning component 109, wherein the support plate 102 is fixed on the base 101, the pouring head 103 is arranged on one side of the support plate 102, the first pushing cylinder 105 is arranged on the base 101, the bottom plate 104 is fixed on the output end of the first pushing cylinder 105, the four side plates are rotatably connected to the bottom plate 104 and are located around the bottom plate 104, the top sealing plate 107 is slidably arranged above the bottom plate 104, the position controller 108 is used to control the opening and closing of the four side plates 106, and the cleaning component 109 is arranged on one side of the support plate 102, and is used to clean the side plates 106 and the bottom plate 104 after the four side plates 106 are opened.

[0031] In this embodiment, the support plate 102 is vertically fixed to one end of the base 101 to support the entire pouring system and ensure its stability. The pouring head 103 is set on one side of the support plate 102 and is used to evenly inject concrete into the pouring area to ensure a continuous and dense pouring process. The first push cylinder 105 is installed on the base 101 and is connected to the bottom plate 104. The bottom plate 104 can be driven by the cylinder to move up and down, thereby adjusting the height of the pouring space to meet the pouring requirements of bridge components of different sizes. Four side panels 106 surround the bottom plate 104 and are movably connected to the bottom plate 104 through a rotating connection mechanism, so that the side panels 106 can be opened and closed as needed to facilitate demolding after concrete pouring. The top sealing plate 107 is slidably arranged above the bottom plate 104 and, in the closed state, can form a closed pouring cavity together with the four side panels 106 to prevent concrete leakage during the pouring process and improve the pouring quality. The position controller 108 is arranged on one side of the device and is connected to the driving mechanism of each side panel 106. It is used to accurately control the opening and closing angles of the four side panels 106, realize automatic adjustment, and ensure the sealing and demoulding convenience during the casting process.

[0032] During operation, the position controller 108 is activated to drive the four side panels 106 to close, and casting material is poured onto the bottom panel 104 through the casting head 103. After casting is completed, the top sealing plate 107 is activated to descend to compact the casting material and hold it for a preset time, so that the casting material is formed into a casting panel. After forming is completed, the position controller 108 controls the four side panels 106 to open, and at the same time, the first push cylinder 105 drives the bottom panel 104 upward, flattening the bottom panel 104 and the four side panels 106. After removing the casting panel, the cleaning assembly 109 cleans the side panels 106 and the bottom panel 104. This makes it easier to cast subsequent components and improves the processing quality of subsequent cast components.

[0033] The side plate 106 includes a side plate body 110 and two corner sealing blocks 111 . The two corner sealing blocks 111 are disposed on both sides of the side plate body 110 .

[0034] The side panel 106 includes a side panel body 110 and two corner sealing blocks 111, and the two corner sealing blocks 111 are respectively arranged at the two side ends of the side panel body 110. The side panel body 110 is made of high-strength metal material, has good structural strength and wear resistance, can withstand the large pressure generated during the concrete pouring process, and ensure the stability and safety of the pouring process. The two corner sealing blocks 111 are fixedly connected to the two ends of the side panel body 110, and form a close contact fitting surface with the adjacent side panels 106. The corner sealing blocks 111 are preferably made of elastic rubber or polymer composite materials, have excellent elasticity and wear resistance, and can effectively fill the gap between adjacent side panels 106 when the side panels 106 are closed, thereby enhancing the sealing performance of the overall pouring cavity.

[0035] The position controller 108 includes four connecting blocks 112, four connecting rods 113, a conical limit frame 114, a second pushing cylinder 115 and a push plate 116. The four connecting blocks 112 are rotatably set on the four side plates 106. A through groove is opened on the connecting block 112. The four connecting rods 113 pass through the four connecting blocks 112 respectively. The push plate 116 is rotatably connected to the four connecting rods 113. The output end of the second pushing cylinder 115 is connected to the push plate 116. The conical limit frame 114 is set above the side plate 106; the second pushing cylinder 115 pushes the push plate 116 to move upward, and the connecting rod 113 rotates along the conical limit frame 114 toward the inner side of the bottom plate 104 to drive the side plate 106 to close.

[0036] The four connecting blocks 112 are rotatably mounted on the outer surfaces of the four side panels 106. Each connecting block 112 has a through slot for engaging a connecting rod 113 to achieve coordinated control. The four connecting rods 113 pass through the through slots of the corresponding connecting blocks 112, forming a sliding connection therewith. This allows the connecting rods 113 to slide within the through slots in a specific direction to accommodate the angular changes of the side panels 106 during opening and closing.

[0037] The push plate 116 is a rigid, integral structure, rotatably connected to the ends of the four connecting rods 113 via a rotating shaft. This allows the push plate 116 to drive the connecting rods 113 to produce coordinated movement when subjected to external forces. The second push cylinder 115 is mounted on the bottom of the device or on a supporting structure, with its output end fixedly connected to the push plate 116. The cylinder's telescopic movement drives the push plate 116 up and down.

[0038] When the second push cylinder 115 drives the push plate 116 upward, the connecting rod 113 is pulled upward by the push plate 116, while being restrained by the tapered limit frame 114 above. The tapered limit frame 114 is fixed above the base plate 104 and positioned outside the space enclosed by the four side plates 106. Its inner wall is inclined, forming a contact guide surface with the connecting rod 113. As the push plate 116 rises, the connecting rod 113, guided by the tapered limit frame 114, rotates inwardly toward the base plate 104, thereby driving the connecting block 112 and the side plates 106 to close inward synchronously, ultimately achieving a tight fit between the four side plates 106 and forming a complete casting cavity. After pouring is completed, the second pushing cylinder 115 moves downward, so that the connecting rod 113 is out of contact with the conical limit frame 114 and is tilted in the connecting block 112. At this time, the first cylinder and the bottom plate 104 are pushed upward. Since the push plate 116 does not move, the connecting rod 113 slides in the connecting block 112, flattening the four side plates 106, making it easier to clean.

[0039] The position controller 108 further includes a limiting rod 117 , which is fixed to one side of the side plate 106 and is used to limit the position of the side plate 106 .

[0040] The position controller 108 further includes a limiting rod 117, which is fixedly mounted on one side of each side panel 106, preferably near the connection between the side panel 106 and the bottom panel 104. The limiting rod 117 is used to mechanically limit the opening angle of the side panels 106, preventing the side panels 106 from excessively rotating during the opening process and affecting the subsequent demolding and flattening operation.

[0041] The cleaning assembly 109 includes a cleaning roller 118, a cleaning drive 119, a cover plate 120 and a bottom collection box 121. The cleaning drive 119 is slidably set on the support plate 102, the cleaning roller 118 is set on the cleaning drive 119, the cover plate 120 is set on one side of the cleaning roller 118, and the bottom collection box 121 is set on the base 101.

[0042] The cleaning driver 119 is slidably arranged on the support plate 102, and realizes the lateral movement function through a guide rail or a slide structure. The cleaning roller 118 is installed at one end of the cleaning driver 119, and can rotate under the drive of the motor and brush or scrape the surface of the side plate 106 or the bottom plate 104 to effectively remove the attached concrete residue. The cover plate 120 is arranged on one side of the cleaning roller 118 to block splashes and guide the waste to fall into the bottom collection box 121 below. The bottom collection box 121 is fixedly arranged on the base 101, located directly below the cleaning area, and is used to collect concrete debris and dust that falls during the cleaning process, so as to facilitate subsequent unified cleaning and recycling.

[0043] The cleaning driver 119 includes a moving motor 122, a support block 123, a gear 124, and a rack 125. The support block 123 is slidably set on the support plate 102, and the rack 125 is fixed on the support plate 102. The gear 124 is rotatably connected to the support block 123 and meshes with the rack 125. The output end of the moving motor 122 is connected to the gear 124, and the cleaning roller 118 is fixed on one side of the gear 124.

[0044] The support block 123 is slidably mounted within a slide rail on the support plate 102. The rack 125 is fixedly mounted along the length of the support plate 102. The gear 124 is rotatably connected to the support block 123 and meshes with the rack 125. The movement motor 122 is fixed to the support block 123, and its output shaft is connected to the gear 124. The drive gear 124 rotates, thereby driving the entire support block 123 to reciprocate along the direction of the rack 125, achieving full coverage cleaning of the side panels 106 and the bottom panel 104 by the cleaning roller 118.

[0045] The support block 123 includes a support block body 126, a pressure block 127 and an elastic member 128. The support block body 126 is slidably set on the support plate 102, the pressure block 127 is slidably set below the support block body 126, the elastic member 128 is set between the support block body 126 and the pressure block 127, and the gear 124 is rotatably connected to the pressure block 127.

[0046] The support block body 126 is slidably mounted on the support plate 102 and serves as the basic load-bearing component of the overall structure. The pressure block 127 is slidably mounted below the support block body 126 and is connected to the support block body 126 via an elastic member 128 (such as a spring or rubber pad). This allows the pressure block 127 to automatically adjust its pressure based on the unevenness of the surface being cleaned, ensuring that the cleaning roller 118 is always in close contact with the surface being cleaned, thereby improving the cleaning effect.

[0047] The cover plate 120 includes a cover plate body 129 and a sweeping brush 130 . The sweeping brush 130 is fixed on one side of the cover plate body 129 .

[0048] The cover plate body 129 is made of lightweight, high-strength material and has an arc-shaped or sloped structure. It covers the cleaning roller 118 and prevents debris generated during the cleaning process from splashing into the external environment. The sweeping brush 130 is fixedly mounted on the side of the cover plate body 129 near the cleaning roller 118. It is usually composed of a wear-resistant brush or a flexible rubber strip. While the cleaning roller 118 is operating, the sweeping brush 130 can pre-sweep loose concrete debris into the cleaning area, improving overall cleaning efficiency and assisting in directing debris into the bottom collection box 121.

[0049] The bridge concrete pouring device with automatic slag cleaning function also includes a conveying component, which includes a splint 131, a third cylinder 132 and a conveying line 133. The splint 131 is slidably arranged on one side of the support plate 102, and the output end of the third cylinder 132 is connected to the splint 131. The conveying line 133 is arranged on one side of the splint 131. The splint 131 is used to clamp the cast parts after forming.

[0050] The clamping plates 131 are a pair of symmetrically arranged metal clamping structures that slide onto one side of the support plate 102. Their sliding path is highly aligned with the casting area, facilitating precise positioning and clamping. The clamping plates 131 are connected to the support plate 102 via rails or guide rods, ensuring stable and reliable clamping, preventing misalignment that could lead to clamping failure or damage to the component surface.

[0051] The third cylinder 132 is fixedly mounted on the support plate 102. Its output end is connected to the clamping plate 131, driving the clamping plate 131 to move horizontally or diagonally to clamp or release the sides of the cast component. The control system adjusts the extension and retraction stroke of the third cylinder 132 to accommodate cast components of varying sizes, providing high versatility and flexibility.

[0052] The conveyor line 133 is located on one side of the clamping plate 131 and moves synchronously with the clamping plate 131. The conveyor line 133 can utilize chain conveying, belt conveying, or roller conveying, depending on the site layout and component weight. Once the clamping plate 131 has completed clamping the cast component, the conveyor line 133 activates and smoothly transports the clamped component along a predetermined route to subsequent processing stations or a storage area, achieving continuous production operations.

[0053] Second embodiment

[0054] The present invention also provides a bridge concrete pouring method with an automatic slag cleaning function, comprising:

[0055] S201 starts the position controller 108 to drive the four side plates 106 to close, and pours the pouring material onto the bottom plate 104 through the pouring head 103;

[0056] Before starting the pouring operation, the system first checks whether each component is in the initial state. After confirming that it is correct, the operating control system starts the position controller 108, and drives the push plate 116 to rise through the second push cylinder 115 inside it. The connecting rod 113 drives the four side panels 106 to rotate inward and close synchronously under the guidance of the conical limit frame 114, forming a closed pouring cavity. The closing process is limited by the limit rod 117 to ensure good sealing between the side panels 106 and avoid leakage during the pouring process. After the closing is completed, the pouring head 103 starts and evenly injects the pre-mixed concrete material into the pouring space surrounded by the four side panels 106 and the bottom plate 104 until it reaches the set height.

[0057] After the pouring is completed in step S202, the top sealing plate 107 is started to descend to compact the pouring material and maintain the compaction time, so that the pouring material is formed into a pouring plate;

[0058] When the concrete pouring is complete, the control system controls the top sealing plate 107 to move downward along the guide rails, pressing against the surface of the pouring material and applying a certain amount of pressure to the concrete to fully compact it, eliminate internal bubbles, and improve the strength and flatness of the finished product. The top sealing plate 107, together with the side plates 106 and the bottom plate 104, forms a closed structure that helps maintain the shape of the pouring material and prevents deformation due to external interference during the solidification process. The top sealing plate 107 will remain in the pouring area for a preset period of time (which can be adjusted according to the concrete mix ratio and ambient temperature) to ensure that the concrete is initially solidified and basically takes shape, forming a pouring plate with a certain strength.

[0059] After the molding is completed in step S203, the position controller 108 controls the four side panels 106 to open, and at the same time, the first push cylinder 105 drives the bottom panel 104 to move upward, flattening the bottom panel 104 and the four side panels 106;

[0060] When the concrete reaches initial set, the control system issues a demolding command. The second push cylinder 115 in the position controller 108 reverses its motion, driving the push plate 116 downward. The connecting rod 113 then moves outward, causing the connecting block 112 and the side panels 106 to open outward, automatically opening the four side panels 106. Simultaneously, the first push cylinder 105 activates, pushing the bottom plate 104 upward, freeing it from the bottom of the cast piece and forming a nearly horizontal position with the opened side panels 106, facilitating subsequent removal of the cast plate. During this step, the design of the corner seals 111 effectively reduces friction between the side panels 106 and the bottom plate 104, improving demolding efficiency.

[0061] After the casting plate is taken out in S204 , the cleaning assembly 109 cleans the side plate 106 and the bottom plate 104 .

[0062] After the casting plate is clamped by the conveying assembly and removed from the device, the cleaning assembly 109 automatically starts. The moving motor 122 in the cleaning driver 119 drives the gear 124 to slide along the rack 125, driving the cleaning roller 118 to move laterally along the surface of the side plate 106 and the bottom plate 104. At the same time, the rotating cleaning roller 118 scrapes or scrubs the remaining concrete residue. The cover plate 120 and the sweeping brush 130 thereon play a shielding and guiding role, preventing debris from splashing and guiding the waste to fall into the bottom collection box 121 for centralized processing. The elastic member 128 in the support block 123 enables the cleaning roller 118 to adapt to surfaces of different flatness, ensuring thorough cleaning. The entire cleaning process does not require manual intervention, realizing automated slag removal operations and preparing for the next cycle of casting work.

[0063] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
