[0021] See also Figure 1 to Figure 2 , which shows the preferred structure of the in-station secondary structure concrete pouring and feeding device provided by the embodiment of the utility model. As shown in the figure, the in-station secondary structure concrete pouring and feeding device comprises: a movable support frame 1, a storage hopper 2 and a handle 3; wherein,

[0023] Specifically, the movable support frame 1 can be a frame structure, which is used to support and fix the storage hopper 2 when pouring concrete to prevent the storage hopper 2 from tipping over or running off. The storage hopper 2 is arranged on the movable support frame 1, which is used to store concrete and can directly discharge the material to the discharge port, so as to directly perform secondary pouring on the secondary structure in the subway station. One or more handles 3 are provided on the top of the storage hopper 2. In this embodiment, there are two handles 3, which are respectively arranged on both sides of the top of the storage hopper 2, so as to hoist and move the storage hopper 2, and facilitate the movement of the storage hopper 2 between the discharge ports. For example, after pouring at the current discharge port, it can be moved to the next discharge port for continued pouring, and manual movement is convenient.

[0024] Continue to see Figure 2 , the storage hopper 2 can be a funnel-shaped structure, and the bottom discharge port of the storage hopper 2 can be provided with a control valve for controlling the on-off of the discharge port. Specifically, the storage hopper 2 can be made of bent steel plates, for example, 3~5mm steel plates are bent and welded, and the seams are welded to form a funnel-shaped structure. Among them, the size of the storage hopper 2 is made according to the size of the holes reserved on site, the production is simple, and the weight is light, and the position can be moved manually. In order to facilitate the control of the discharge of the storage hopper 2, preferably, the bottom discharge port of the storage hopper 2 can be provided with a control valve for controlling the on-off of the discharge port, so that when the storage hopper 2 is aligned with the reserved discharge port position and the discharge is poured, the control valve is opened to discharge the concrete; and the control valve can be closed during movement to cut off the discharge of the concrete.

[0025] In this embodiment, the handle 3 can be made of round steel and connected to the storage hopper 2 by welding. Specifically, the handle 3 is made of round steel bent into a U-shaped structure, and both open ends thereof can be fixed to the top of the storage hopper 2 by welding to ensure the stability of the connection between the two, thereby ensuring the stability of the storage hopper 2 during hoisting and movement, and preventing it from falling during movement.

[0026] In this embodiment, the movable support frame 1 may include: a circumferential fixing ring 11 and at least three vertical support rods 12; wherein, the circumferential fixing ring 11 is used to be sleeved on the outer circumference of the storage hopper to circumferentially fix the storage hopper; at least three vertical support rods 12 are arranged along the circumference of the circumferential fixing ring 11, and the top end of each of the vertical support rods 12 is connected to the circumferential fixing ring 11 for vertically supporting the circumferential fixing ring 11.

[0027] Specifically, the circumferential fixing ring 11 can be formed by bending and welding steel bars according to the size of the storage hopper 2. The vertical support rods 12 can also be a steel bar structure, which is evenly arranged along the circumference of the circumferential fixing ring 11, and the top ends can be welded to the circumferential fixing ring 11, and the bottom can be supported on the working surface. In order to further improve the stability of the movable support frame 1, preferably, a reinforcement rod 13 is further provided between any two adjacent vertical support rods 12, and its two ends are respectively connected to the two adjacent vertical support rods 12, and a plurality of the reinforcement rods 13 form a polygonal structure. Among them, the reinforcement rod 13 can also be a steel bar structure.

[0028] In this embodiment, the method of using the device is as follows: the tank truck transfers concrete to the large hopper on the forklift through the barrel, and the hopper is moved by the forklift to the top of the processed storage hopper 2, and the lower opening of the storage hopper 2 is aligned with the reserved discharge port position in advance, and the material is discharged, that is, the material in the hopper is lowered into the storage hopper 2, and the material is discharged from the storage hopper 2 to the discharge port. After the construction is completed, the storage hopper 2 can be moved to the next discharge port manually.

[0029] See also Figure 3 , which is another structure of the in-station secondary structure concrete pouring and unloading device provided by the embodiment of the utility model. In this embodiment, the movable support frame 1, the storage hopper 2 and the handle 3 can be the same as the above structure. Further, the bottom of the movable support frame 1 is provided with a moving part 4 for driving the movable support frame 1 to move. Further, the bottom of the movable support frame 1 can also be rotatably connected with a telescopic support leg 5, so that the movable support frame 1 has a fixed support state and a walking state. In the fixed support state, the telescopic support leg 5 rotates to a vertical position and extends to contact the support surface and lift the movable support frame 1, so that the moving part 4 is suspended to provide fixed support through the telescopic support leg 5; in the walking state, the telescopic support leg 5 retracts to a suspended state and rotates to a folded position, and the moving part 4 contacts the support surface to provide mobile support through the moving part 4 and drive the movable support frame 1 to move.

[0030] Specifically, there can be multiple moving parts 4, which are located at the four corners of the bottom of the movable support frame 1 to provide multiple walking and moving support points, thereby ensuring the stability of the movement of the device. Among them, one or more of the moving parts 4 can be used as a driving wheel to drive the movable support frame 1 to move.

[0031] The telescopic legs 5 may be hydraulic legs or other telescopic structures, which are not limited in this embodiment. The telescopic legs 5 may be rotatably connected to the movable support frame 1 through a hinge plate to realize the rotation of the telescopic legs 5, thereby realizing the conversion of the telescopic legs 5 between the vertical position and the folded position; wherein the hinge plate may be a universal hinge plate to drive the telescopic legs 5 to rotate 360°. In this embodiment, there may be four telescopic legs 5 to ensure the stability of the fixed support of the movable support frame 1.

[0032] Of course, the telescopic legs 5 can also be directly vertically arranged and fixedly connected to the movable support frame 1, so as to achieve the switching of the telescopic legs 5 being suspended in the air or the moving part 4 being suspended in the air only by telescopic adjustment, that is, the telescopic legs 5 are arranged on the movable support frame 1, and in the fixed support state, the telescopic legs 5 are telescopically adjusted to contact the support surface, so that the moving part 4 is suspended in the air, so as to perform fixed support through the telescopic legs 5; in the walking state, the telescopic legs 5 are telescopically adjusted to the suspended state, and the moving part 4 contacts the support surface, so as to perform walking and movable support through the moving part 4.

[0033] In this embodiment, the telescopic legs 5 are rotatably connected to the movable support frame 1, and in particular, the structure of the rotatable connection and the telescopic legs 5 can realize the switching of the movable support frame 1 between two states; at the same time, in the fixed support state, it can be rotated to a horizontal position or other direction position for folding, which can avoid interference or collision between the telescopic legs 5 and other objects when the sorting device moves; in the walking state, it can be rotated to a vertical position, and then through telescopic adjustment, the bottom of the telescopic legs 5 can contact the support surface and gradually lift the movable support frame 1, so that the sorting device as a whole is supported by the telescopic legs 5, and the moving part 4 is suspended, and it can be switched to the fixed support state.

[0034] See also Figure 4, which is a structural block diagram of a movable support frame provided by an embodiment of the utility model. As shown in the figure, the movable support frame may also be provided with a movable part state sensor 6, which is used to detect whether the movable part is in a suspended state, and may also send a movable part state signal of the movable part 4 to the controller 7. Specifically, the movable part state sensor 6 may be a pressure sensor, which may be arranged on the movable part 4, and is used to detect the pressure on the movable part 4, so as to detect whether the movable part 4 is in a suspended state. For example, when the pressure on the movable part 4 is zero, the movable part 4 is in a suspended state, otherwise the movable part 4 is not in a suspended state, and may send a movable part state signal of the movable part 4 to the controller 7. Of course, the movable part state sensor 6 may also be other sensors to detect whether the movable part 4 is in a suspended state.

[0035] In this embodiment, the movable support frame may also be provided with a leg state sensor 8 for detecting whether the telescopic leg 5 is in a suspended state, and may also send a leg state signal of the telescopic leg 5 to the controller 7. Specifically, the leg state sensor 8 may determine the state of the movable support frame 1 by detecting whether the telescopic leg 5 is in a suspended state, and combining the moving part state signal of the moving part 4, that is, when the telescopic leg 5 is in a suspended state and the moving part 4 is not in a suspended state, the movable support frame 1 is in a walking state, and the moving part 4 may drive the sorting device to move as a whole; when the telescopic leg 5 is not in a suspended state and the moving part 4 is in a suspended state, the movable support frame 1 is in a fixed support state.

[0036] The moving part status sensor 6 and the leg status sensor 8 are connected to a controller 7, which is used to receive the moving part status signal obtained by the moving part status sensor 6 and the leg status signal obtained by the leg status sensor 8, and control the rotation and extension of the telescopic legs 5 according to the moving part status signal and the leg status signal to realize the switching of the state of the movable support frame 1, that is, when it is necessary to move to the working position, the telescopic legs 5 are retracted and rotated to the folded position so that the moving part 4 contacts the support surface; when it is necessary to carry out material pouring, the telescopic legs 5 are rotated to a vertical position and extended to contact the support surface, and the movable support frame 1 is gradually lifted to make the moving part 4 suspended, and after fixed support by the telescopic legs 5, the material is poured through the storage hopper 2.

[0037] See also Figure 5, which is a structural block diagram of the leg state sensor provided by the embodiment of the utility model. As shown in the figure, the leg state sensor 8 may include: a rotation direction sensor 81, a length sensor 82 and a leg state judgment unit 83; wherein the rotation direction sensor 81 is used to detect the direction of the current rotation position of the telescopic leg 5, so as to detect whether the telescopic leg 5 is in a vertical position or a folded position; the length sensor 82 is used to detect the length of the telescopic leg 5, so as to detect whether the length of the telescopic leg 5 is extended to a preset support length or retracted to a preset suspended length; the leg state judgment unit 83 is connected to the rotation direction sensor 81 and the length sensor 82 respectively, and is used to analyze and judge whether the telescopic leg 5 is in a suspended state according to the direction of the current rotation position of the telescopic leg 5 detected by the rotation direction sensor 81 and the length of the telescopic leg 5. Specifically, the rotation direction sensor 81 can be set on the movable support frame 1, and detect the direction of the current rotation position of the telescopic leg 5 by detecting the position of the hinge plate; of course, the direction of the current rotation position of the telescopic leg 5 can also be directly detected, and this is not limited in this embodiment. The length sensor 82 detects the length of the telescopic leg 5 itself, and the leg state judgment unit 83 analyzes and judges whether the telescopic leg 5 is in a suspended state based on the direction of the current rotation position of the telescopic leg 5 detected by the rotation direction sensor and the length of the telescopic leg 5. That is, when the telescopic leg 5 is in a vertical position, the bottom end of the telescopic leg 5 (relative to the vertical position) can be judged based on the length of the telescopic leg 5. Figure 3 The distance between the movable part 4 and the movable support frame 1 can be measured to compare the distance between the movable part 4 and the movable support frame 1, thereby driving the telescopic legs 5 to determine whether they are in a suspended state. It can also be determined whether the movable part 4 is in a suspended state based on this, so as to determine the state of the movable support frame 1. Among them, the preset support length and the preset suspension length can be determined according to actual conditions, as long as the length of the telescopic legs 5 is the preset support length and in a vertical position, the bottom end of the telescopic legs 5 contacts the support surface, and the movable part 4 is suspended at the same time; similarly, when the length of the telescopic legs 5 is the preset suspension length and in a vertical position, the telescopic legs 5 are suspended, and the movable part 4 contacts the support surface at the same time.

[0038] In summary, the secondary structure concrete pouring and unloading device provided in the present embodiment is simple to manufacture and easy to move and operate. There is no need to use a pump truck or a ground pump during the concrete pouring process. A tank truck can be used in conjunction with a bottom forklift to transport materials. The tank truck ensures that the single-time concrete transportation volume is controlled within 3-5 cubic meters, eliminating the hidden danger of initial setting of concrete, and also greatly reduces the generation of solid waste construction waste, reduces the investment in related equipment such as pump trucks, and can also save construction time and reduce labor input.
