[0002] Factory production of bridges can improve production efficiency and ensure more stable production quality, and has become the main production method.

[0003] In bridge prefabrication, the use of gantry concrete placing booms in conjunction with formwork pit pouring is a core process. First, formwork is installed inside the formwork pit to create the pouring space. The gantry concrete placing boom moves along tracks to the top of the pit and evenly delivers concrete into the pit in pre-set horizontal layers. Then, a vibrator is used to compact the concrete, ensuring density. A gantry concrete placing boom typically consists of a gantry frame and a placing bin that can move along the length of the gantry frame (the length of the formwork pit). The movement of the placing bin allows concrete to be poured into the pit.

[0004] Currently, fabric bins typically have only one discharge gate, resulting in low fabric precision. After fabrication, significant manual leveling is required, leading to low fabrication efficiency. Utility Model Content

Detailed Implementation

[0020] In bridge prefabrication, the use of gantry concrete placing booms in conjunction with formwork pit pouring is a core process. First, formwork is installed inside the formwork pit to create the pouring space. The gantry concrete placing boom moves along tracks to the top of the pit and evenly delivers concrete into the pit in pre-set horizontal layers. Then, a vibrator is used to compact the concrete, ensuring density. A gantry concrete placing boom typically consists of a gantry frame and a placing bin that can move along the length of the gantry frame (the length of the formwork pit). The movement of the placing bin allows concrete to be poured into the pit.

[0029] The following describes in detail the overall structure, working principle, and technical effects of the fabric bin and gantry fabric placing machine provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0030] Please refer to Figure 1 The gantry-type concrete placing machine provided by this utility model is used to place concrete into the mold pit during the precasting of precast concrete bridges.

[0031] Please refer to Figure 1 In this embodiment, the gantry-type material placing machine includes a gantry frame (not shown) and a material placing bin 100. The gantry frame is generally arranged along the length of the mold cavity to provide support and a track for the material placing bin 100 to move. The material placing bin 100 is movably installed on the gantry frame and can move along the gantry frame to place material into the mold cavity.

[0032] Please refer to Figures 1 to 7In this embodiment, the concrete hopper 100 includes a hopper body 110, a material guiding assembly 130, a moving assembly 150, a hopper door 170, and a drive assembly 190. The hopper body 110 has a receiving cavity 111 for receiving concrete, and a discharge port 113 is provided at the bottom of the hopper body 110 in the width direction. The material guiding assembly 130 is disposed within the receiving cavity 111 and is capable of guiding the concrete within the receiving cavity 111 to the discharge port 113. The moving assembly 150 is disposed within the hopper body 110 to drive the hopper body 110 to move along the gantry frame. Multiple hopper doors 170 are included, and the multiple hopper doors 170 are sequentially and movably installed at the discharge port 113 in the width direction of the hopper body 110. The drive assembly 190 is connected to the hopper body 110 and is drively connected to all hopper doors 170, capable of driving any hopper door 170 to change the opening position and degree of the discharge port 113.

[0033] In this embodiment, a discharge port 113 is provided at the bottom width direction of the bin body 110, and multiple bin doors 170 are provided. The multiple bin doors 170 are sequentially and movably installed at the discharge port 113 in the width direction of the bin body 110. A drive assembly 190 is provided, which is connected to the bin body 110 and drives all the bin doors 170. In this way, according to the material laying requirements, the control assembly can drive any bin door 170 to move, thereby changing the opening position and opening degree of the discharge port 113, thereby achieving precise material laying and improving the problem of having to spend a lot of manpower to level the material after laying, thus improving the material laying efficiency.

[0034] Specifically, the silo body 110 has a shape that is wider at the top and narrower at the bottom, forming a semi-cylindrical surface 115 at the bottom. The discharge port 113 is a rectangular notch located on the side wall of the semi-cylindrical surface 115, extending along the width of the silo body 110. Multiple silo doors 170 are installed sequentially along the width direction. Closing all silo doors 170 will seal the discharge port 113, while opening any one or more silo doors 170 will allow the concrete inside the silo body 110 to flow out. Adjusting the opening degree of the silo doors 170 can adjust the size of the opening, thereby regulating the flow rate.

[0035] In this embodiment, each of the compartment body 110 and the corresponding installation position of the compartment door 170 is provided with a first connecting lug 117. Each of the compartment doors 170 is provided with a second connecting lug 171. The first connecting lug 117 and the second connecting lug 171 are hinged together by a hinge axis, and the drive assembly 190 can drive the compartment door 170 to rotate along the hinge axis.

[0036] In this embodiment, the top of the compartment door 170 is hinged, which facilitates the drive assembly 190 to drive the compartment door 170 to open and close.

[0037] Please refer to Figures 1 to 7Furthermore, the drive assembly 190 includes a plurality of telescopic drive rods 191. The compartment body 110 extends downward and is provided with a connecting seat 119, on which a plurality of hinge seats 121 are provided. Each compartment door 170 is connected to at least one telescopic drive rod 191, and the other end of the telescopic drive rod 191 is hinged to the hinge seat 121.

[0038] This embodiment uses a telescopic rod to control the opening and closing of the compartment door 170, which has a simple structure and is easy to operate.

[0039] Specifically, the front and rear side walls of the compartment 110 are sloped, with the spacing gradually decreasing downwards. A connecting seat 119 is located on the front side of the compartment 110 and is fixed to the compartment 110 by welding or screws. The connecting seat 119 extends vertically downwards to the corresponding bottom position of the compartment 110. Multiple hinge seats 121 are sequentially arranged at the bottom of the connecting seat 119, with intervals between them.

[0040] Furthermore, all the bottom outer sides of the compartment doors 170 are provided with hinged lugs 173. The end of the telescopic drive rod 191 is hinged to the hinged lugs 173.

[0041] In this embodiment, a hinge lug 173 is provided on the outer side of the compartment door 170, allowing the end of the telescopic drive rod 191 to be hinged to the hinge lug 173. This allows for better control of opening and closing of the compartment door 170. When the telescopic drive rod 191 is shortened, the compartment door 170 can be pulled open. As the degree of shortening increases, the opening degree of the compartment door 170 also increases until it is fully open. The extension of the telescopic drive rod 191 corresponds to the closing process of the compartment door 170. As the degree of extension increases, the opening degree of the compartment door 170 gradually decreases until it is closed.

[0042] In this embodiment, the fabric bin 100 also includes a hydraulic pump station 210, which is disposed on the connecting seat 119. The telescopic drive rods 191 are all hydraulic cylinders, which are connected to the hydraulic pump station 210.

[0043] In this embodiment, by setting up a hydraulic pump station 210 and setting the telescopic drive rod 191 as a hydraulic cylinder, the opening and closing of the compartment door 170 can be better driven.

[0044] Specifically, a mounting platform 123 is provided in the middle of the connecting seat 119, and the hydraulic pump station 210 is installed on the mounting platform 123. Each hydraulic cylinder is connected to the hydraulic pump station 210 through pipes and hydraulic valves. The hydraulic valves can be O-type three-position four-way directional valves, which can realize the control of extension and retraction, and can achieve pressure holding in the middle position.

[0045] Please refer to Figures 1 to 7Furthermore, the hopper door 170 is arc-shaped, and its bottom end is provided with an outward-facing first flange 175. The end of the first flange 175 is bent inward to form a second flange 177. The hopper body 110 is provided with an outward-facing third flange 125 at the bottom of the discharge port 113. When the hopper door 170 is closed, the first flange 175 abuts against the third flange 125, and the second flange 177 extends and covers the outside of the third flange 125.

[0046] This embodiment, by setting the first flange 175 and the second flange 177, can enhance the structural strength of the door 170 and improve its sealing performance when closed. In particular, the second flange 177 can block sand and gravel particles trapped between the first flange 175 and the third flange 125, thus improving the problem of gap leakage.

[0047] Please refer to Figures 1 to 7 Furthermore, the left and right sides of the door 170 are also provided with outward fourth flanges 179, which can significantly enhance the mechanical strength of the door 170.

[0048] In this embodiment, there are five doors 170 and five hydraulic cylinders. The five hydraulic cylinders are connected to the five doors 170 in a one-to-one correspondence and can be controlled individually or together.

[0049] Of course, the number of doors 170 and the number of hydraulic cylinders can be adapted to the needs and the size of the compartment 110.

[0050] Please refer to Figures 1 to 7 In this embodiment, the material guiding assembly 130 includes a first drive motor 131 and a first material guiding spiral 133. The first material guiding spiral 133 is rotatably mounted at the bottom of the hopper and is positioned corresponding to the discharge port 113. The outer periphery of the first material guiding spiral 133 is provided with clockwise spiral blades, and the other part is provided with counterclockwise spiral guiding blades. The first drive motor 131 is mounted on the outside of the hopper and is connected to the first material guiding spiral 133 for driving the first material guiding spiral 133 to rotate.

[0051] In this embodiment, a first guiding spiral 133 is provided at the discharge port 113, which can control the discharge rate and avoid uneven discharge due to gravity. The outer periphery of the first guiding spiral 133 is provided with clockwise spiral blades, and the other part is provided with counterclockwise spiral guiding blades, which can realize the guiding of material from both sides to the middle or from the middle to both sides.

[0052] Specifically, bearing seats 127 are respectively provided at both ends of the semi-cylindrical surface 115 formed at the bottom of the silo 110. The first guide screw 133 is rotatably installed on the bearing seat 127 and is set corresponding to the discharge port 113. This can prevent the concrete in the silo 110 from flowing out of the discharge port 113 in a disorderly manner under the action of gravity, and thus achieve controllable discharge.

[0053] Furthermore, the material guiding assembly 130 also includes a second material guiding spiral 135 and a second drive motor 137. The second material guiding spiral 135 is disposed within the hopper and located above the first material guiding spiral 133, spaced apart from the first material guiding spiral 133. The outer periphery of the second material guiding spiral 135 is provided with clockwise spiral blades, and the other part is provided with counterclockwise spiral guiding blades. The second drive motor 137 is disposed on the side of the hopper away from the first drive motor 131, and the second drive motor 137 is connected to the second material guiding spiral 135 to drive the second material guiding spiral 135 to rotate.

[0054] In this embodiment, a second guiding spiral 135 is provided at the top to guide the material downwards, preventing the concrete from solidifying and hindering downward flow. The first drive motor 131 and the second drive motor 137 are positioned on both sides of the hopper body 110 for a more rational layout and to avoid interference.

[0055] Please refer to Figures 1 to 7 In this embodiment, a rectangular frame 230 is provided around the perimeter of the hopper, and the frame 230 is provided with an isolation net 231. The moving component 150 includes track wheels 151 disposed on both sides of the width direction of the frame 230 and a drive motor 153 fixedly connected to the frame 230 and pulsatorically connected to the track wheels 151.

[0056] In this embodiment, the frame 230 provides better support for the compartment 110 and facilitates the matching of the distance between the track wheels 151 and the track. Furthermore, the frame 230, by laying the isolation netting 231, can also form a platform for easy maintenance.

[0057] In summary, this embodiment provides a discharge port 113 at the bottom width of the bin body 110 and multiple bin doors 170, which are sequentially and movably installed at the discharge port 113 in the width direction of the bin body 110. A drive assembly 190 is provided, which is connected to the bin body 110 and drives all the bin doors 170. In this way, the opening position and degree of the discharge port 113 can be changed by controlling the movement of any bin door 170 according to the material laying requirements, thereby achieving precise material laying and improving the problem of having to spend a lot of manpower to level the material after laying, thus improving the material laying efficiency.

[0058] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
