Technical Field

[0001] The utility model relates to the field of metering flat cars, and specifically relates to a metering flat car. Background Technique

[0002] In the field of traditional concrete component production, the concrete pipe pile industry has been formed earlier. In the field of concrete pipe piles, a closed-mode pumping and cloth-feeding method of closing the mold first and then cloth-feeding has emerged, that is, the cloth-feeding pipe is inserted into the cavity mold, and concrete slurry is pumped into the cloth-feeding pipe from the other end of the cloth-feeding pipe. Along with the movement of the pipe pile mold, the concrete is spread over the mold cavity. During the process of the cloth-feeding pipe entering the empty mold and cloth-feeding, a metering flat car is required to carry the mold and move back and forth, and at the same time record the cloth-feeding data. Due to the long length of the mold itself, the main structure design has one common point: all adopt a wire rope traction mechanism.

Detailed implementation manners

[0039] Embodiment 1:

[0040] Please refer to Figures 1 - 13 , the present utility model provides a technical solution: As Figure 1As shown in the figure, a metering flat car includes a moving track 1 and multiple weighing cars 2. The weighing cars 2 are fixedly connected to the upper side of the moving track 1. Pipe pile molds are placed on the weighing cars 2. Multiple sets of rotating parts, preferably multiple sets of rollers, are fixedly connected to the moving track 1. The moving track 1 drives the weighing cars 2 to move, facilitating the loading of concrete into the pipe pile molds. A slide rail 5 is arranged between adjacent weighing cars 2, and the slide rail 5 is vertically and fixedly connected to the moving track 1; A chain is arranged in the middle of the moving track 1, and the lower side of the chain is meshed and connected with a driving device 7. The driving device 7 rotates to drive the chain to rotate, thereby driving the moving track 1 to reciprocate. The weighing car 2 can weigh the pipe pile mold when moving on the moving track 1. A limiting structure 3 is fixedly connected to one end of the moving track 1, which is used to limit the extreme positions of the left and right movement of the chain. A storage box 4 (see Figure 6 ) is fixedly connected to the other end of the moving track 1, which is used to collect the concrete falling off from the pipe pile mold; It should be noted that the pipe pile mold is closed at one end and has an opening at the other end.

[0041] As Figures 2 - 3 shown in the figure, the weighing car 2 includes a weighing platform 20, a weighing base 23 fixedly connected to the moving track 1, and multiple stabilizing components 25 fixedly connected to the weighing base 23. The weighing platform 20 is installed on the upper side of the weighing base 23; The stabilizing components 25 are located outside the weighing platform 20. An active limiting ball 253 is installed on the stabilizing component 25 facing the outer side wall of the weighing platform 20. The moving distance of the weighing platform 20 on the weighing base 23 is limited by the limiting ball 253;

[0042] The weighing platform 20 includes at least a pair of symmetrically arranged placing parts 21 and a fixing frame one 22. The placing parts 21 are fixedly connected to the upper side of the fixing frame one 22 and are used for placing the pipe pile mold; The fixing frame one 22 is fixedly connected to the upper side of the weighing base 23;

[0043] The weighing base 23 includes a fixing frame two 24 fixedly connected to the moving track 1 and multiple weighing parts 26 fixedly connected to the upper side of the fixing frame two 24. The upper sides of the weighing parts 26 are fixedly connected to the fixing frame one 22; The weighing parts 26 are evenly distributed at both ends of the fixing frame two 24. The weighing parts 26 are weighing sensors, which can weigh the pipe pile mold placed on the placing part 21 and during the pipe pile concrete placing.

[0044] The stabilizing component 25 includes a limiting member 251 and a stabilizing frame 252. The limiting member 251 penetrates the stabilizing frame 252. The end of the limiting member 251 facing the first fixing frame 22 is movably connected to a limiting ball 253 for limiting the moving distance of the first fixing frame 22. The limiting member 251 includes a screw rod 2511, a nut 2512, and a limiting post 2514. The screw rod 2511 penetrates the stabilizing frame 252. One end of the screw rod 2511 is threadedly connected to the nut 2512, and the other end faces the first fixing frame 22 and is fixedly connected to the limiting post 2514. A circular groove is provided in the middle of the limiting post 2514 to match the limiting ball 253. The limiting ball 253 is movably connected in the circular groove. The limiting ball 253 faces the first fixing frame 22 and does not directly contact the first fixing frame 22, leaving a certain distance. When the first fixing frame 22 shakes, the amplitude of the shake of the first fixing frame 22 can be limited by the limiting ball 253. Since the limiting ball 253 can rotate, it is not easy to affect the measurement data of the weighing base 23 when limiting the first fixing frame 22, ensuring the accuracy of weighing.

[0045] As Figures 4 - 5 shown, the limiting structure 3 includes a limiting shell 31 and a limiting cover 32. A set of teeth 33 is fixedly connected to the bottom inside the limiting shell 31. The chain is located between the set of teeth 33 to ensure the non-deviation of the movement of the chain. The limiting cover 32 is bolted to the upper side of the teeth 33. The limiting cover 32 is located inside the limiting shell 31. The chain is restricted between the teeth 33 and the limiting cover 32.

[0046] A free conveying device 6 is arranged on the side of the moving track 1. The conveying device 6 can slide above the moving track 1 through the slide rail 5, so as to place the pipe pile mold on the placing part 21 through the conveying device 6; a feeding device 8 is arranged near the end of the storage box 4. The feeding device 8 includes a fixedly connected feeding center 81 and a feeding pipe 82. The feeding pipe 82 is used to insert into the pipe pile mold for concrete conveying, and the feeding center 81 pumps the concrete into the feeding pipe 82.

[0047] Working principle: As Figures 8 - 13 shown, the operator starts multiple conveying devices 6 and extends them upward, raises the pipe pile molds pre-placed on the multiple conveying devices 6 over the obstacles and moves them to the moving track 1 through the slide rail 5, and then shortens the conveying devices 6 to lower the pipe pile molds and place them on the placing part 21. The empty conveying device 6 moves in the reverse direction, disengages from the moving track 1 and returns to its position for pre-receiving the next pipe pile mold.

[0048] Start the driving device 7. The rotation of the driving device 7 drives the chain to rotate, and the chain drives the moving track 1 to move towards the feeding center 81. During the process that the moving track 1 drives the pipe pile mold to move, the feeding pipe 1 will be aligned and inserted into the pipe pile mold. When the end of the feeding pipe 1 abuts against the innermost bottom end of the pipe pile mold far from the feeding center 81, the driving device 7 stops rotating (the abutting distance can be calculated by installing an encoder on the driving device 7 through the existing counting method to calculate the number of rotations of the motor). The weighing member 26 records the weight of the first fixing frame 22 and the pipe pile mold on it at this time, which is convenient for calculating the weight of the concrete transported into the pipe pile mold subsequently. Start the feeding center 81, and the feeding center 81 pumps concrete into the feeding pipe 82 and transports it into the pipe pile mold through the feeding pipe 82. At the same time, the driving device 7 is started again and moves in the reverse direction, thereby driving the moving track 1 to move away from the feeding center 81. While the moving track 1 drives the load-bearing vehicle 2 and the pipe pile mold to move away from the feeding center 81 and the feeding pipe 82 transports concrete, the weighing member 26 monitors the weight of the concrete in the pipe pile mold in real time online to ensure that when the moving track 1 moves, the concrete is transported, the weighing changes, and the change is within the compliant weight range, so as to ensure that the finally cast pipe pile meets the production weight requirements.

[0049] During the process that the moving track 1 moves away from the feeding center 81, affected by the concrete in the pipe pile mold, the pipe pile mold is likely to drive the first fixing frame 22 to move horizontally or axially along the pipe pile mold. When the moving amplitude is too large, it will touch the limit ball 253 to limit the moving distance of the first fixing frame 22. The limit ball 253 can rotate in the limit column 2154, and the contact area between the limit ball 253 and the side of the first fixing frame 22 is very small, which is not easy to affect the weighing accuracy of the weighing member 26 and will not cause sliding and abrasion damage to the first fixing frame 22; when the pipe pile mold is separated from the feeding pipe 82, the pipe pile mold is filled with concrete. Close the feeding center 81 and the driving device 7, and the worker plugs the end of the pipe pile mold close to the feeding pipe 82 with a sealing plug. At this time, the concrete extruded from the end of the pipe pile mold falls into the storage box 4, which ensures the cleanliness of the working environment and also avoids waste of concrete; finally, the crane lifts the pipe pile mold and places it on the conveying device 6 to be transported away, and so on to transport concrete into the pipe pile mold.

[0050] Embodiment 2

[0051] On the basis of Embodiment 1, as Figure 6 shown, the side wall of the placing part 21 is stepped, forming a first placing area 211 and a second placing area 212. The second placing area 212 is close to the outside of the placing part 21 and is used to place pipe pile molds of different specifications.

[0052] Embodiment 3

[0053] On the basis of Embodiment 2, as Figure 7As shown, a placing pad 41 is rotatably connected to the outside of the placing part 21. The placing pad 42 can rotate to the middle of the placing part 21 and protrude from the middle of the placing part 21. The side surface is stepped, forming a third placing area 411 and a fourth placing area 412. When the placing pad 41 rotates to the middle of the placing part 21, the third placing area 411 and the fourth placing area 412 face upward, for placing pipe pile molds of different specifications.
