It should also be noted that the aforementioned Z axis, X axis and Y axis are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0022] The structure of the railway T-beam casting mold is as follows Figure 2 As shown in the middle T-beam mold 10, the T-beam mold 10 includes two parts, a horizontal flange plate and a vertical web plate, and between the two parts is the reinforcing rib mold 20 of the T-beam, and the cavity of the reinforcing rib mold 20 is connected with the cavity of the T-beam mold 10. At present, in the construction of prefabricated T-beams, the material is basically laid by a paving machine, that is, the material is laid by opening the door below. When the gate below the paving machine is opened, the concrete material falls freely into the cavity of the reinforcing rib mold 20 and the cavity of the T-beam mold 10. However, this material laying method has a large unloading volume, and this material laying method is not applicable to the position of the reinforcing rib mold 20, which is easy to cause the concrete material to be scattered outside the mold when unloading, so the material laying at these positions needs to be supplemented by manual paving.

[0023] Combine 1 to Figure 2 As shown, the utility model provides a prefabricated T-beam concrete placing machine, including a discharge port, at which a first gate 1 and a second gate 2 are opened and closed. In the pouring direction, the width of the first gate 1 is greater than the width of the second gate 2, and the width of the second gate 2 is used to correspond to the width of the reinforcing rib mold 20.

[0024] Specifically, the pouring direction refers to the moving direction of the feed machine, which is usually the length direction of the T-beam mold 10, and in this specification, it can be understood as the Y-axis direction. The discharge port is rectangular as a whole, and the length direction of the discharge port is consistent with the length direction of the T-beam mold 10. The first gate 1 and the second gate 2 are arranged along the Y-axis along the discharge port and are respectively hinged at the discharge port through a rotating shaft, so that the first gate 1 and the second gate 2 can rotate relative to the discharge port around the axis of the rotating shaft, so that when the first gate 1 and the second gate 2 are both in a closed state, the first gate 1 and the second gate 2 realize the closure of the discharge port, and when the first gate 1 and / or the second gate 2 are in an open state, the first gate 1 and / or the second gate 2 realize the opening of the discharge port, so that the discharge and pouring can be carried out according to the pouring requirements. Further, in the pouring direction (Y-axis direction), the width of the second gate 2 is used to correspond to the width of the reinforcing rib mold 20, that is, the width of the second gate 2 is approximately equal to or slightly smaller than the width of the reinforcing rib mold 20, so that when the second gate 2 is just above the reinforcing rib mold 20, the concrete can completely fall into the reinforcing rib mold 20 from the second gate 2, and relative to the cavity length of the reinforcing rib mold 20, the cavity of the T-beam mold 10 is longer, therefore, setting the width of the first gate 1 to be greater than the width of the second gate 2 can ensure the pouring efficiency of the T-beam mold 10. When pouring the T-beam, the concrete placing machine moves to the T-beam mold 10 after receiving the material at the receiving point. Since the T-beam body is relatively long, the segmented pouring is adopted, first pouring the web of the T-beam mold 10, and then pouring the flange plate of the T-beam mold 10. The concrete placing machine first moves to the top of the web of the T-beam mold 10. At this time, the first gate 1 and the second gate 2 can be opened at the same time to unload the material, and move along the length direction of the T-beam mold 10 to cast the web of the T-beam mold 10. After casting to the specified height (determined by the actual casting), the concrete placing machine repeatedly moves along the flange plate of the T-beam mold 10 to cast the flange plate of the T-beam mold 10. Since the T-beam is designed with a reinforcing rib mold 20, it is difficult to ensure that the reinforcing ribs are cast at the same time when casting the flange plate and the web. At this time, it is necessary to control the moving speed of the concrete placing machine. When the concrete placing machine moves to the second gate 2 just above the reinforcing rib mold 20, the second gate 2 is opened and the first gate 1 is closed. Concrete is cast at the reinforcing rib position. Since the width of the second gate 2 corresponds to the width of the reinforcing rib mold 20, the concrete falls into the reinforcing rib mold 20 under the guidance of the second gate 2 to avoid the concrete from being scattered outside the mold, thereby avoiding manual paving.

[0025] Therefore, in this embodiment, the first gate 1 and the second gate 2 are opened and closed at the discharge port to realize the segmented setting of the discharge port, and the opening and closing states of the first gate 1 and the second gate 2 can be selected in a targeted manner during the pouring process, and in the pouring direction, the width of the first gate 1 is greater than the width of the second gate 2, and the width of the second gate 2 corresponds to the width of the reinforcing rib mold 20, so that the first gate 1 and the second gate 2 can be opened at the same time for laying materials at the conventional position of the precast beam, thereby improving the laying efficiency; and at the position of the reinforcing rib of the precast beam, only the second gate 2 can be opened to realize laying of a small amount of materials, which not only realizes automatic laying, but also avoids the concrete from being scattered outside the mold, thereby avoiding manual paving, so as to improve the efficiency of the construction method.

[0026] Optionally, combined Figure 1 As shown, two groups of first gates 1 are provided, and in the pouring direction, the second gate 2 is located between the two groups of first gates 1. In this way, the second gate 2 and the two groups of first gates 1 increase the discharge area of ​​the material port, and further realize the segmented setting of the material port, thereby improving the pouring efficiency.

[0027] Optionally, combined Figure 1 As shown, the prefabricated T-beam concrete placing machine also includes a hopper 3, a feeding port is provided at the bottom of the hopper 3, and the hopper 3 is used to be movably arranged above the prefabricated beam mold, and the first gate 1 and the second gate 2 are installed on the hopper 3.

[0028] Specifically, the prefabricated beam mold refers to a T-beam mold 10, the feed port is located at the bottom of the hopper 3, the hopper 3 can be moved above the T-beam mold 10 by existing means, and the first gate 1 and the second gate 2 are hinged to the side wall of the hopper 3 through a pin shaft.

[0029] In this way, a discharge port is provided at the bottom of the hopper 3 and is used to be moved above the precast beam mold, and the first gate 1 and the second gate 2 are installed on the hopper 3. In this way, after the first gate 1 and the second gate 2 are opened, the concrete can quickly fall into the T-beam mold 10 from the discharge port by gravity, thereby improving the concrete pouring efficiency.

[0030] Optionally, the cross-section of the hopper 3 in the axial direction, i.e., the Y-axis direction, is V-shaped, and the first gate 1 and the second gate 2 are located between the two axial side walls of the hopper 3. In this way, when the first gate 1 and the second gate 2 are both closed, concrete can be prevented from leaking from both ends of the hopper 3 in the axial direction.

[0031] Optionally, combined Figure 1 As shown, the prefabricated T-beam concrete placing boom also includes a second hydraulic cylinder 4, which is installed on the hopper 3, and the second gate 2 is hinged to the hopper 3. The output end of the second hydraulic cylinder 4 is drivingly connected to the second gate 2 to realize the opening and closing of the second gate 2 at the discharge port.

When the output end of the second hydraulic cylinder 4 is extended, the second gate 2 rotates toward the discharge port to achieve the closure of the discharge port. When the output end of the second hydraulic cylinder 4 is retracted, the second gate 2 rotates away from the discharge port to achieve the opening of the discharge port.

[0033] In this way, the second hydraulic cylinder 4 is installed on the hopper 3, and the output end of the second hydraulic cylinder 4 is connected to the second gate 2 hinged on the hopper 3 to realize the opening and closing of the second gate 2 at the discharge port. In this way, the second gate 2 is directly driven, and the opening and closing process of the second gate 2 is simplified, and the opening and closing process of the second gate 2 is further controlled, so as to adjust the unloading efficiency and improve the casting efficiency.

[0034] Optionally, the second gate 2 includes two second door panels, the two second door panels are symmetrically arranged relative to the casting direction, and the two second hydraulic cylinders 4 are respectively connected to the two second door panels in a corresponding driving manner.

[0035] Specifically, the second gate 2 includes two second door panels, and the second hydraulic cylinder 4 and the second door panels are correspondingly driven and connected, that is, one second hydraulic cylinder 4 only drives one second door panel to rotate, and one second hydraulic cylinder 4 and one second door panel form a group, and the two groups of second hydraulic cylinders 4 and second door panels are symmetrical with respect to the casting direction (Y-axis direction). When the material discharge port is closed, the two second door panels are driven by the corresponding second hydraulic cylinders 4 to rotate toward each other until the material port is sealed.

[0036] In this way, the two second door panels of the second gate 2 are symmetrically arranged relative to the pouring direction, and the two second hydraulic cylinders 4 are respectively driven and connected to the two second door panels. In this way, during pouring, one group of second hydraulic cylinders 4 and the second door panels or two groups of second hydraulic cylinders 4 and the second door panels can be selectively opened to adjust the pouring efficiency of the reinforcing rib mold 20 and realize flexible pouring of the reinforcing rib mold 20.

[0037] Optionally, combined Figure 1 and Figure 2 As shown, the prefabricated T-beam concrete placing machine also includes a first hydraulic cylinder 5, which is installed on the hopper 3, and the first gate 1 is hinged to the hopper 3. The output end of the first hydraulic cylinder 5 is drivingly connected to the first gate 1 to realize the opening and closing of the first gate 1 at the discharge port.

[0038] Specifically, the setting principle of the first hydraulic cylinder 5 is the same as that of the second hydraulic cylinder 4. In this way, the first hydraulic cylinder 5 realizes direct driving of the first gate 1, thereby simplifying the opening and closing process of the first gate 1, and further realizing controllable opening and closing process of the first gate 1, thereby realizing adjustment of unloading efficiency to improve pouring efficiency.

[0039] Optionally, combined Figure 1 and Figure 2 As shown, the first gate 1 includes two first door panels, the two first door panels are symmetrically arranged relative to the casting direction, and the two first hydraulic cylinders 5 are respectively drivingly connected to the two first door panels.

[0040] Specifically, the first gate 1 includes two first door panels, and the first hydraulic cylinder 5 and the first door panels are correspondingly driven and connected, that is, one first hydraulic cylinder 5 only drives one first door panel to rotate, and one first hydraulic cylinder 5 and one first door panel form a group, and the two groups of first hydraulic cylinders 5 and the first gate 1 are symmetrical with respect to the casting direction (Y-axis direction). When the feed port is closed, the two first door panels are driven by the corresponding first hydraulic cylinders 5 to rotate toward each other until the feed port is sealed.

[0041] In this way, the two first door panels of the first gate 1 are symmetrically arranged relative to the pouring direction, and the two first hydraulic cylinders 5 are respectively driven and connected to the two first door panels. In this way, during pouring, one group of first hydraulic cylinders 5 and first door panels or two groups of first hydraulic cylinders 5 and first door panels can be selectively opened to adjust the pouring efficiency of the web and flange plates of the T-beam mold 10, thereby realizing flexible pouring of the T-beam mold 10.

[0042] Optionally, combined Figure 1 As shown, the prefabricated T-beam concrete placing machine also includes a vibration motor 6, which is installed on the hopper 3 to achieve vibration of the inner wall of the hopper 3.

[0043] Specifically, the vibration motor 6 can be assembled on the outer wall of the hopper 3 by bolts. When the vibration motor 6 is started, the vibration motor 6 realizes the vibration of the inner wall of the hopper 3. The vibration can act on the concrete in the hopper 3 to make the concrete vibrate to prevent the concrete from solidifying.

[0044] In this way, the vibration motor 6 is installed on the hopper 3 to achieve vibration of the inner wall of the hopper 3. The vibration motor 6 realizes vibration of the concrete in the hopper 3 to avoid solidification of the concrete, so that the concrete is always in a fluid state to improve the distribution efficiency.
