When relocation is needed, cranes or other lifting equipment are required for dismantling, which is time-consuming and labor-intensive. In addition, pump pipes of sufficient length are required for installation. The longer the pump pipe, the more likely it is to become blocked during the pouring process. Therefore, we propose a ballastless track construction concrete pouring platform. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, please refer to Figure 1-4This utility model provides a technical solution: a ballastless track construction concrete pouring platform, including an electric flatbed trolley 1, with symmetrical front and rear limiting steel grooves 2 fixedly connected to the left and right sides of the lower end of the electric flatbed trolley 1, and symmetrical front and rear hydraulic support legs 3 provided on the left and right sides of the lower end of the electric flatbed trolley 1, and a ground pump mechanism 4 fixedly connected to the upper end of the electric flatbed trolley 1.

[0025] A frame 7 is fixedly connected to the upper left side of the electric flatbed trolley 1. A generator 5 is fixedly connected to the inner cavity of the frame 7. The addition of the frame 7 provides protection for the generator 5. The output end of the generator 5 is electrically connected to the electric flatbed trolley 1. The addition of the generator 5 can provide power for the movement of the electric flatbed trolley 1 itself, without the need for a tractor to pull it. The upper front and rear sides of the frame 7 are fixedly connected with symmetrical lifting lugs 6. The addition of the lifting lugs 6 makes it easy to use a crane to lift the generator 5 onto the electric flatbed trolley 1 for installation.

[0026] It should be noted that the specific installation method, circuit connection method, and control method of the hydraulic support leg 3 and generator 5 in this utility model are all conventional designs and are standard design methods used by designers. The ground pump mechanism 4 and frame 7 are fixed to the electric flatbed cart 1 by bolts. When pouring is required, the four hydraulic support legs 3 are activated to lift the electric flatbed cart 1 and create a certain gap with the rails to prevent the pump truck from vibrating and affecting the rails during pouring. At the same time, square timber is used to pad the inner cavity of the limiting steel channel 2 to further improve the stability of the equipment. When moving to another site, the hydraulic support legs 3 only need to be retracted and the square timber padding the inner cavity of the limiting steel channel 2 removed. The equipment can then be quickly moved to the next pouring point via the rails. The relocation does not require complex disassembly or large equipment assistance. The integrated design of the ground pump mechanism 4 and the electric flatbed cart 1 reduces the equipment handling links and has high relocation efficiency. It is especially suitable for linear construction scenarios such as bridge decks and can quickly adapt to the position requirements of different pouring surfaces.

[0027] The ground pump mechanism 4 includes a ground pump body 41. Two support groups 43 are fixedly connected to the lower sides of both the front and rear ends of the ground pump body 41. Two symmetrical lifting lugs 44 are fixedly connected to the upper left and right sides of the ground pump body 41. Two symmetrical fixing lugs 42 are fixedly connected to the lower right and lower left sides of the outer surface of the ground pump body 41. A discharge port 45 is provided in the middle of the right end of the ground pump body 41. A connecting group 46 is fixedly connected to the discharge port 45. The ground pump body 41 is attached to the upper end of the electric flatbed trolley 1. All four fixing lugs 42 are fixedly connected to the electric flatbed trolley 1 by bolts.

[0028] In detail, the specific installation method, circuit connection method, and control method of the ground pump body 41 in this utility model are all conventional designs and are standard design methods used by designers. First, the ground pump body 41 is hoisted to a suitable position on the upper part of the electric flatbed truck 1 by hooking the lifting lug 44 with a crane. Then, the four support groups 43 are adjusted so that the lower side of the four support groups 43 fits against the electric flatbed truck 1 and is fixed to the electric flatbed truck 1 with bolts. Then, the four fixing lugs 42 are used in conjunction with bolts to fix the ground pump body 41 to the electric flatbed truck 1, making the installation of the ground pump body 41 and the electric flatbed truck 1 more secure and stable. Concrete in the ground pump body 41 is sprayed out from the inner cavity of the discharge port 45. Because of the space constraints in linear construction sites such as bridge decks and tunnels, the connection angle needs to be considered when connecting with the pump pipe. Therefore, a connecting group 46 is added to the right end of the discharge port 45. By adjusting the installation shape of the connecting group 46, it can be connected to the pump pipe more flexibly.

[0029] The connecting assembly 46 includes a connecting pipe 461. Flanges 465 are fixedly connected to both the left and right sides of the outer surface of the connecting pipe 461. A rotating bracket 462 is sleeved and connected to the outer surface of the connecting pipe 461. Flange 463 is rotatably connected to the right side of the outer surface of the rotating bracket 462. Flange 463 is fixedly connected to flange 465 on the right side by bolts. An arc-shaped pipe 464 is fixedly connected to the inner cavity of flange 463. The left side of the inner cavity of the arc-shaped pipe 464 is sleeved and connected to the right side of the outer surface of the connecting pipe 461. Flange 465 on the left side is fixedly connected to the discharge port 45 by bolts, and the inner cavity of the discharge port 45 communicates with the inner cavity of the connecting pipe 461.

[0030] In detail, the rotating bracket 462 can rotate on the outer surface of the connecting pipe 461, so that the flange 1 463 drives the arc-shaped pipe 464 to be installed on the right-end flange 2 465 at different rotation angles by bolts. Then, the pump pipe is connected through the arc-shaped pipe 464. In addition, by removing the bolts of the flange 1 463 and the flange 2 465 on the same side, the arc-shaped pipe 464 is pulled and the rotating bracket 462 moves to the right side of the outer surface of the connecting pipe 461 through the flange 1 463, so that the arc-shaped pipe 464 is separated from the outer surface of the connecting pipe 461. Then, the rotating bracket 462 and the flange 1 463 are rotated and pushed to the left to rotate the bracket 462, so that the right-end flange 2 465 can be connected to the straight pump pipe by bolts, which can be connected to the pump pipe more flexibly.

[0031] Example 2, please refer to Figure 5-6This utility model provides a technical solution: a concrete pouring platform for ballastless track construction, wherein each of the four support groups 43 includes a support sleeve 431, an inner sliding column 433 is slidably connected to the inner cavity of the support sleeve 431 on the same side, a base plate 434 is fixedly connected to the lower end of the inner sliding column 433, a hydraulic rod 438 is fixedly connected to the upper end of the base plate 434 on the same side away from the inner sliding column 433, the upper end of the hydraulic rod 438 on the same side is fixedly connected to the support sleeve 431, and a limit hole 437 is opened on the lower side of both the left and right ends of the support sleeve 431 on the same side;

[0032] Several limiting holes 435 are opened at both ends of the inner sliding column 433 on the same side. The inner cavity of the limiting hole 437 and the inner cavity of the limiting hole 435 on the same side are provided with limiting pins 436. U-shaped sleeve rods 432 are sleeved and connected on both sides of the outer surface of the limiting pin 436 on the same side. An insertion hole is opened on one side of the limiting pin 436 on the same side. The inner cavity of the insertion hole is provided with a pin 439. The upper part of the side of the four support sleeves 431 away from the U-shaped sleeve rods 432 is fixedly connected to the pump body 41. The four base plates 434 are all fixedly connected to the electric flatbed trolley 1 by bolts.

[0033] In detail, the specific installation method, circuit connection method, and control method of the hydraulic rod 438 in this utility model are all conventional designs and are standard design methods used by designers. The pump body 41 is hoisted onto the electric flatbed truck 1 using a crane, and the pump body 41 is fixedly installed on the electric flatbed truck 1 using fixing lugs 42 and bolts. When it is necessary to adjust the height of the pump body 41, the pin 439 is pulled upwards to disengage from the inner cavity of the insertion hole. Then, the limiting pin 436 is pulled out sequentially from the inner cavity of the limiting hole 435, the limiting hole 437, and the U-shaped sleeve 432. Then, the hydraulic rod 438 is activated, which causes the base plate 434 to slide the inner sliding column 433 downward in the inner cavity of the support sleeve 431 to a suitable position. Next, the limiting pin 436 is inserted into the inner cavity of the limiting hole 435, the limiting hole 437 and the U-shaped sleeve 432 in sequence to restrict the sliding of the inner sliding column 433 and the inner cavity of the support sleeve 431. Finally, the pin 439 is inserted into the insertion hole opened by the limiting pin 436, and the base plate 434 is installed with the electric flatbed trolley 1 with bolts. This achieves the purpose of adjusting the installation height of the ground pump body 41, making the use of the device more flexible.
