Technical Field
[0001] The utility model belongs to the technical field of simulated casting devices, and more specifically relates to a ballastless track self-compacting concrete simulated casting device. Background Art
[0002] In the construction of ballastless track, it is necessary to pour self-compacting concrete under the track slab through the pouring holes on the track slab. Since the poured self-compacting concrete is blocked by the track slab, it is impossible to know whether the poured self-compacting concrete has defects such as water marks through the pouring process adopted. This requires a device that can simulate the pouring process of self-compacting concrete and observe the pouring quality of self-compacting concrete after pouring and forming, but there is no such device on the market at present.

[0024] Please also read Figure 1 and Figure 3Now, the self-compacting concrete simulation pouring device for ballastless track provided by the utility model is described. The self-compacting concrete simulation pouring device for ballastless track comprises a base plate 1, a pouring mold 2 and a cover plate 3. The base plate 1, the pouring mold 2 and the cover plate 3 are included. The base plate 1 is arranged horizontally. The pouring mold 2 is located on the base plate 1, and a pouring space 21 is provided in the pouring mold 2, and the upper end and the lower end of the pouring space 21 are both open ends. The cover plate 3 is arranged on the pouring mold 2 to cover the upper end of the pouring space 21, and a pouring hole 31 connected with the pouring space 21 is provided on the cover plate 3.
[0025] Compared with the prior art, the ballastless track self-compacting concrete simulation pouring device provided by the utility model pours concrete into the pouring space 21 through the pouring hole 31 and restricts the cover plate 3 from moving upward, thereby simulating the pouring process of the self-compacting concrete. After the pouring is completed, the cover plate 3 avoids the space above the pouring mold 2 and allows the pouring mold 2 to move upward and separate from the poured concrete. Then, it can be observed whether the poured concrete has defects such as water marks, thereby avoiding the lack of a device on the market that can simulate the pouring process of self-compacting concrete and observe the pouring quality of the self-compacting concrete after pouring.
[0026] In this embodiment, the base plate 1 can be fixed on the ground.
[0027] In some embodiments, see Figure 3 The ballastless track self-compacting concrete simulation pouring device also includes a limit block 4. The limit block 4 is fixed on the bottom plate 1, and the limit block 4 is slidably arranged in the pouring space 21 and has a gap with the cover plate 3. The pouring space 21 is located between the limit block 4 and the cover plate 3 for pouring concrete. When pouring concrete into the pouring space 21, the bottom plate 1 limits the movement of the pouring mold 2 in the horizontal direction through the limit block 4.
[0028] In some embodiments, the cover plate 3 is slidably connected to the bottom plate 1 in the horizontal direction, so that the cover plate 3 can slide to avoid the space above the casting mold 2. Since the cover plate 3 is slidably connected to the bottom plate 1 in the horizontal direction, when pouring concrete into the casting space 21, the bottom plate 1 can limit the cover plate 3 from moving upward, and the cover plate 3 can limit the casting mold 2 from moving upward. When the casting is completed, the cover plate 3 slides to avoid the space above the casting mold 2, and the casting mold 2 can be driven to move upward to separate from the cast concrete.
[0029] In some embodiments, in order to realize the sliding connection between the cover plate 3 and the bottom plate 1 in the horizontal direction, the following method can be adopted: Figure 1 and Figure 2 See the structure shown. Figure 1 and Figure 2The ballastless track self-compacting concrete simulation pouring device further comprises a connection assembly, which comprises a connection slide rail 51 and a connection slider 52. The connection slide rail 51 is arranged along the sliding direction of the cover plate 3 and is fixedly arranged on the bottom plate 1. The connection slider 52 is slidably arranged on the connection slide rail 51, and the connection slider 52 is fixedly connected to the cover plate 3. The cover plate 3 and the bottom plate 1 are slidably connected by the sliding cooperation between the connection slider 52 and the connection slide rail 51.
[0030] In some embodiments, see Figure 3 The ballastless track self-compacting concrete simulation pouring device also includes two supporting plates 6. The two supporting plates 6 are respectively arranged on opposite sides of the pouring mold 2, and the supporting plates 6 are horizontally arranged and fixedly connected to the pouring mold 2. After the simulated pouring is completed, the operator can support the pouring mold 2 to move upward through the two supporting plates 6, which is more convenient to operate.
[0031] In some embodiments, see Figure 2 The ballastless track self-compacting concrete simulation pouring device also includes a limit shaft 7. The limit shaft 7 is vertically arranged, and the limit shaft 7 slides through the cover plate 3 and the bottom plate 1, so that the cover plate 3 can be limited to slide, so that the cover plate 3 keeps covering the upper end of the pouring space 21. When the pouring is completed, the limit shaft 7 is driven to slide upward to separate from the bottom plate 1, and then the cover plate 3 can be driven to slide to avoid the space above the pouring mold 2.
[0032] In some embodiments, see Figure 2 The ballastless track self-compacting concrete simulation pouring device also includes a rubber sleeve 8. The rubber sleeve 8 is sleeved and fixed on the top of the limit shaft 7. The operator holds the rubber sleeve 8 with his hand and then drives the limit shaft 7 to move upward, which can increase the comfort of the hand.
[0033] In some embodiments, the above-mentioned characteristic limiting axis 7 can be adopted as follows Figure 2 See the structure shown. Figure 2 The middle part of the limiting shaft 7 is a contraction section 71 that contracts inwardly in the circumferential direction, and the contraction section 71 is slidably penetrated in the cover plate 3. In this way, the limiting shaft 7 can be prevented from sliding away from the cover plate 3, thereby preventing the limiting shaft 7 from being lost.
[0034] In some embodiments, the above-mentioned characteristic connection components can be used as follows Figure 1 and Figure 2 See the structure shown. Figure 1 and Figure 2 The connection assembly further includes two anti-dropout blocks 53. The two anti-dropout blocks 53 are fixed on the connection slide rail 51, and the two anti-dropout blocks 53 are respectively located on both sides of the connection slider 52 along the length direction of the connection slide rail 51. The connection slider 52 can be prevented from sliding off the connection slide rail 51 by the limiting of the two anti-dropout blocks 53.
[0035] In some embodiments, see Figure 1 The number of connecting components is two, and the two connecting components are respectively located on both sides of the casting mold 2 along the first horizontal direction, and the first horizontal direction is perpendicular to the connecting slide rail 51. In this way, the cover plate 3 can be subjected to a more uniform force and slide more smoothly.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
