Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figure 1As shown in Embodiment 1, a complete set of tooling for a high-speed railway subgrade contact network foundation includes: a casting template 1, positioning steel plates 2, a casting hopper 3, and a support 4; the casting template 1 is a rectangular frame; there are two positioning steel plates 2, which are arranged vertically, and an angle steel is provided between the two positioning steel plates 2, which are fixedly connected by the angle steel; a feed inlet 2.1 is provided at the center of the positioning steel plate 2, and the lower positioning steel plate 2 is fixedly installed on the top of the casting template 1; the discharge port of the casting hopper 3 is greater than the top surface of the casting template 1 in the height direction; the support 4 includes a first support 4.1 and a second support 4.2, the casting hopper 3 is fixedly connected to the first support 4.1, the first support 4.1 is located above the second support 4.2, and the second support 4.2 is greater than the height of the casting template 1 in the height direction.

[0024] When using this device, firstly, the casting template 1 is fixedly installed on the ground. The first support 4.1 is moved so that the outlet of the casting material port corresponds to the inlet 2.1. Cement is poured into the casting hopper 3. The cement enters the inlet 2.1 from the outlet through gravity, so that the cement can enter the casting template 1 and complete the roadbed casting work.

[0025] The first bracket 4.1 is fixedly installed on the top of the second bracket 4.2. The discharge port of the casting hopper 3 is opposite to the inlet 2.1. The support legs of the second bracket 4.2 are located on both sides of the casting hopper 3.

[0026] When moving the first support 4.1, the position of the second support 4.2 needs to be adjusted so that the outlet of the pouring hopper 3 corresponds to the inlet 2.1. The support feet of the second support frame are then in contact with the outer walls of both sides of the pouring template 1, so that the second support 4.2 can be stably placed on the ground to prevent it from shaking during cement pouring. After the second support 4.2 is stably placed, cement is poured into the pouring hopper 3. The cement enters the inlet 2.1 from the outlet through gravity, allowing it to enter the pouring template 1 and complete the subgrade pouring. This improves the construction accuracy of the railway contact network foundation and embedded parts, while also simplifying on-site operation and allowing the template to be reused.

[0027] like Figures 2 to 5 As shown, in Embodiment 2, the first bracket 4.1 is slidably mounted on the top of the second bracket 4.2, and the support foot of the second bracket 4.2 is disposed on one side of the second bracket 4.2.

[0028] Before use, slide the first bracket 4.1 to the left end of the second bracket 4.2, and then reposition the second bracket 4.2 so that the first bracket 4.1 is located on one side of the casting template 1. After installation, slide the first bracket 4.1 to the right end of the second bracket 4.2.

[0029] The top of the second bracket 4.2 is provided with a groove 4.3, and both sides of the bottom end of the first bracket 4.1 are slidably installed in the groove 4.3.

[0030] When the first support 4.1 is slidable, it can drive the displacement of the pouring hopper 3, so that the outlet of the pouring hopper 3 can correspond to the inlet 2.1, so that cement can enter the pouring template 1 from the pouring hopper 3 through the outlet.

[0031] An extension plate 4.4 is fixedly connected to the outer wall of the discharge port of the casting hopper 3. The extension plate 4.4 is square. The bottom surface of the extension plate 4.4 is at the same height as the discharge port in the height direction. A door panel 5 is slidably arranged below the extension plate 4.4, and the top surface of the door panel 5 is attached to the bottom end of the extension plate 4.4.

[0032] When the discharge port and the inlet 2.1 correspond, and the door plate 5 is within the range of the extension plate 4.4, it can prevent cement from falling out of the inside of the pouring hopper 3, so as to prevent cement from falling out of the pouring hopper 3 when the pouring hopper 3 is moved. When the door plate 5 exceeds the range of the extension plate 4.4, it can open the discharge port, so that cement can fall from the pouring hopper 3 into the pouring template 1 to complete the pouring of cement.

[0033] Both sides of the bottom surface of the extension plate 4.4 are provided with L-shaped sliding grooves 4.5. Both sides of the bottom surface of the door panel 5 are slidably provided with latches 6. The latches 6 include a sliding plate 6.1, a first moving rod 6.2 and a second moving rod 6.3. The first moving rod 6.2 and the second moving rod 6.3 are respectively fixedly installed at both ends of the sliding plate 6.1, and the end of the second moving rod 6.3 connected to the sliding plate 6.1 extends downward. The surfaces of the first moving rod 6.2 and the second moving rod 6.3 are in contact with the end face of the door panel 5.

[0034] When the latch 6 slides on the door panel 5, the outer surfaces of the first moving rod 6.2 and the second moving rod 6.3 contact the end face of the door panel 5, which enables the latch 6 to slide stably on the door panel 5. At the same time, in the initial state, one end face of the door panel 5 and the extension plate 4.4 are on the same plane, which makes it easy for the latch 6 to lock the door panel 5 and the extension plate 4.4 in the initial state, preventing the door panel 5 and the extension plate 4.4 from misaligning when the pouring hopper 3 moves, thus preventing the discharge port from opening.

[0035] Sliding blocks 6.4 are fixedly installed on the opposite sides of the two sliding plates 6.1. Sliding grooves 5.1 are opened at both ends of the door panel 5. The sliding blocks 6.4 are slidably installed inside the sliding grooves 5.1. A fixing plate 5.2 is provided between the two sliding plates 6.1. The fixing plate 5.2 is fixedly installed on the bottom surface of the door panel 5. A spring 5.3 is fixedly connected between the sliding plates 6.1 and the fixing plate 5.2.

[0036] When the latch 6 slides on the door panel 5, the sliding block 6.4 can slide inside the second groove 5.1. When the two latches 6 move in opposite directions, the spring 5.3 is stretched, and the latch 6 is pulled by the elastic force of the spring 5.3, which can reset the latch 6.

[0037] The first moving rod 6.2 is slidably installed in the slide groove 4.5. The second moving rod 6.3 has an inclined plate 2.2 at one end away from the first moving rod 6.2. The inclined plate 2.2 is fixedly installed on the top surface of the lower positioning steel plate 2. The feed port 2.1 of the upper positioning steel plate 2 is U-shaped, and the extension plate 4.4 can be inserted into the discharge port of the upper positioning steel plate 2.

[0038] When the latch 6 is in the initial position, the first moving rod 6.2 is located at the end of the slide groove 4.5. At this time, when the latch 6 moves, the first moving rod 6.2 is blocked by the slide groove 4.5. The latch 6 can drive the door panel 5 and the extension plate 4.4 to move, so that the pouring hopper 3 can move, which is convenient for adjusting the displacement of the pouring hopper 3. At the same time, the extension plate 4.4 is inserted into the inlet 2.1 to complete the alignment operation of the outlet and inlet 2.1 of the pouring hopper 3.

[0039] The door panel 5 continues to move, causing the second moving rod 6.3 to contact the inclined surface. At this time, the extension plate 4.4 is blocked by the feed port 2.1, and the second moving rod 6.3 is blocked by the inclined plate 2.2, which allows the second moving rod 6.3 to move on the inclined surface of the inclined plate 2.2 and drive the first moving rod 6.2 to undergo lateral displacement. When the first moving rod 6.2 is located at the corner of the slide 4.5, the two latches 6 are in the unlocked state, and at this time the door panel 5 can undergo relative displacement with the extension plate 4.4.

[0040] When the first moving rod 6.2 slides to the other end of the chute 4.5, the extension plate 4.4 is blocked by the feed inlet 2.1, and the door plate 5 continues to move, which allows the door plate 5 to exceed the range of the extension plate 4.4 and open the discharge port of the pouring hopper 3, allowing cement to flow out from the inside of the pouring hopper 3.

[0041] After the pouring is completed, the first support 4.1 is moved in the opposite direction, so that the first moving rod 6.2 moves to the corner of the chute 4.5. At the same time, the door panel 5 covers the extension plate 4.4 to prevent cement from flowing out of the outlet. At this time, the sliding plate 6.4 is subjected to the force of the spring 5.3, which pulls the first moving rod 6.2 back to the end of the chute 4.5 and locks the door panel 5 and the extension plate 4.4. Then, the first support 4.1 is pulled out from the range of the positioning steel plate 2.

[0042] Connecting plates 5.4 are fixedly installed on both sides of the door panel 5. A T-shaped plate 5.5 is fixedly installed on the end of the connecting plate 5.4 away from the door panel 5. A handle 5.6 is fixedly installed on the top of the T-shaped plate 5.5. The handle 5.6 is slidably installed in the groove 4.3.

[0043] When the handle 5.6 moves, it can drive the T-shaped plate 5.5 to move. When the T-shaped plate 5.5 moves, it can drive the connecting plate 5.4 to move. When the connecting plate 5.4 moves, it can drive the door panel 5 to move. When the door panel 5 moves, it can drive the latch 6 to move, thereby driving the pouring hopper 3 to move.

[0044] Compared to Embodiment 1, Embodiment 2 uses a set of support 4 in conjunction with multiple sets of casting templates 1. After one casting is completed, the support 4 can be removed separately, and the cement inside the casting template 1 will not flow out. The remaining cement can be transported to the next required casting template 1 by moving the support 4. The amount of cement inside the casting template 1 can be controlled. During turnover, only the support 4 needs to be moved separately, which improves work efficiency.

[0045] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
