[0046] In existing technologies, the sprue nozzle is usually lifted to the installation position on the tundish by manual lifting, so as to connect and fix the sprue nozzle to the tundish. However, manual lifting is labor-intensive, increases the labor force, and is also prone to damaging the sprue nozzle during the lifting process, which also reduces the installation accuracy of the sprue nozzle.

[0047] To solve the above problems, such as Figure 1 and Figure 2 As shown, this embodiment provides a sprue installation auxiliary vehicle, which includes a vehicle body 1, a load-bearing component 2, and a winch assembly 3. The load-bearing component 2 is slidably connected to the vehicle body 1 and supports the sprue. The winch assembly 3 is mounted on the vehicle body 1, and its output end is connected to the load-bearing component 2. The winch assembly 3 drives the load-bearing component 2 to move up and down relative to the vehicle body 1. When the sprue supported by the load-bearing component 2 is moved to below the tundish, the winch assembly 3 can drive the load-bearing component 2 to lift the sprue, facilitating its positioning and installation on the tundish. This eliminates the need for manual handling and lifting of the sprue, reducing labor costs and preventing damage from human operation, thus improving the protection of the sprue. Furthermore, the support of the load-bearing component 2 ensures the installation accuracy of the sprue at the tundish. In addition, the winch assembly 3's method of driving the load-bearing component 2 to lift and move the sprue makes operation convenient and the structure reliable.

[0048] It should be noted that the above-mentioned sprue auxiliary installation vehicle enables the bearing component 2 to hold the sprue at the corresponding height position for a long time, thereby ensuring that the fire putty or other refractory sealing material at the sprue and tundish installation position is completely cured, and ensuring the sealing of the connection between the sprue and the tundish.

[0049] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, the winch assembly 3 includes a fixing member 31, a drum (not shown), a guide wheel 32, and a traction rope 33. The fixing member 31 is mounted on the vehicle body 1, the drum is rotatably mounted on the fixing member 31, the guide wheel 32 is rotatably mounted on the vehicle body 1, one end of the traction rope 33 is connected to the drum, and the other end of the traction rope 33 passes around the guide wheel 32 and connects to the load-bearing assembly 2. This winch assembly 3's structural design allows the drum to be wound or released by rotating it, enabling the traction rope 33 to pull the load-bearing assembly 2 up and down relative to the vehicle body 1. The guide wheel 32 provides guidance for the traction direction of the traction rope 33, ensuring the reliability of the traction rope 33 in moving the load-bearing assembly 2. Optionally, in this embodiment, two guide wheels 32 are spaced apart on the vehicle body 1, each with a traction rope 33 wound around it. The two guide wheels 32 jointly guide the traction rope 33, further improving the reliability of guiding the traction rope 33. In other embodiments, the specific number of guide wheels 32 can be set according to requirements. Optionally, in this embodiment, the traction rope 33 is a steel wire rope, which has the advantage of structural reliability. In other embodiments, the traction rope 33 can be a polymer rope or other metal rope.

[0050] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, the winch assembly 3 also includes a drive handle 34, which is connected to the drum. The operator can manually rotate the drive handle 34 to drive the drum to rotate, thus winding or releasing the traction rope 33. This configuration makes the winch assembly 3 a manual winch, reducing costs. Specifically, the drive handle 34 can be connected to the drum via a gear set. Since the specific structure of the drive handle 34 connected to the drum via a gear set is prior art, it will not be described further here. In other embodiments, the rotation of the drum can also be driven by a motor and a gear set, making the winch assembly 3 an electric winch, which makes operation more convenient. It should be noted that the winch assembly 3 has a built-in locking mechanism that automatically locks the relative position of the drum, thereby locking the length of the traction rope 33. Since the specific structure of the locking mechanism and the locking principle are prior art, they will not be described further here.

[0051] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, the sprue auxiliary installation vehicle also includes a guide assembly 4, which includes a guide rod 41 and a slider 42. The slider 42 is slidably sleeved on the guide rod 41. The guide rod 41 extends along the moving direction of the bearing assembly 2 (up and down direction in the figure). One of the guide rod 41 and the slider 42 is disposed on the vehicle body 1, and the other of the guide rod 41 and the slider 42 is disposed on the bearing assembly 2. By setting the guide assembly 4, guidance is provided for the lifting and lowering movement of the bearing assembly 2 relative to the vehicle body 1, ensuring the stability and reliability of the lifting and lowering movement of the sprue supported by the bearing assembly 2, thereby ensuring the installation accuracy of the sprue at the bottom of the tundish. In addition, by designing the guide assembly 4 in the form of a guide rod 41 and a slider 42, the structure is simple and the operation is reliable. Optionally, in this embodiment, the guide rod 41 is disposed on the vehicle body 1, and the slider 42 is disposed on the bearing assembly 2. In other embodiments, the guide rod 41 is disposed on the bearing assembly 2, and the slider 42 is disposed on the vehicle body 1. Optionally, in this embodiment, the slider 42 can be a slider. Optionally, in this embodiment, two guide components 4 are spaced apart, and the two guide components 4 together provide guidance for the movement of the support component 2, further ensuring the stability and reliability of the support component 2 in supporting the lifting and lowering movement of the water inlet. In other embodiments, the specific number of guide components 4 can be set according to requirements.

[0052] In this embodiment, as Figure 1 and Figure 2 As shown, the vehicle body 1 includes a vehicle frame 11 and multiple casters 12. A fixing member 31 is mounted on the vehicle frame 11, and the vehicle frame 11 is slidably connected to the load-bearing component 2. The multiple casters 12 are spaced apart at the bottom of the vehicle frame 11. This structural design of the vehicle body 1 facilitates movement in all directions, thereby enabling the transport and movement of the sprue. Optionally, in this embodiment, four casters 12 are spaced apart at the bottom of the vehicle frame 11. In other embodiments, the specific number of casters 12 can be set according to requirements. It should be noted that in this embodiment, the guide rod 41 is fixedly mounted on the vehicle frame 11.

[0053] Optionally, in this embodiment, a plurality of hand handles 111 are provided at intervals on the vehicle frame 11, so that the operator can push the vehicle 1 to move by holding the hand handles 111.

[0054] Optionally, in this embodiment, the top of the vehicle frame 11 can be detachably fixed to the bottom of the intermediate tundish. After the vehicle body 1 moves to the bottom of the intermediate tundish, it can be lifted by a forklift, so that the top of the vehicle frame 11 can be detachably fixed to the bottom of the intermediate tundish, ensuring the accuracy of the alignment between the sprue and the installation position of the intermediate tundish when the supporting component 2 supports the sprue as it rises. After the sprue installation is completed, the top of the vehicle frame 11 is separated from the bottom of the intermediate tundish, and the vehicle frame 11 is lowered by a forklift, making it easy to push the entire empty vehicle body 1 out from the bottom of the intermediate tundish. Optionally, the top of the vehicle frame 11 can be detachably fixed to the bottom of the intermediate tundish with bolts.

[0055] Optionally, in this embodiment, a mounting plate 112 is provided on the vehicle frame 11, and a guide wheel 32 is rotatably connected to the mounting plate 112. Furthermore, it should be noted that the mounting plate 112 is located above the support assembly 2. When placing the sprue on the sprue auxiliary mounting vehicle, the sprue can first be elastically fixed to the mounting plate 112 using an elastic element, then the sprue is placed on the support assembly 2, and then the elastic element on the sprue is removed. This placement method facilitates the placement of the sprue on the support assembly 2 and avoids collisions with the sprue during the support process. It should be noted that the elastic element can be a tension spring.

[0056] Optionally, in this embodiment, as Figures 1-4As shown, the supporting component 2 includes a support frame 21 and a positioning tray 22. The support frame 21 supports the sprue and is slidably connected to the vehicle frame 11. The support frame 21 is also connected to the traction rope 33. The positioning tray 22 is detachably mounted on the support frame 21 and has a positioning protrusion 221 for positioning and engaging with the sprue's outlet. This structural design of the supporting component 2 allows the positioning tray 22 to be detached from the support frame 21 during sprue installation. The support frame 21 then supports the sprue to a first preset height. A separation ring is installed between the outer wall of the sprue and the inner wall of the seat brick, pre-installing the sprue onto the seat brick of the tundish. The support frame 21 is then lowered to separate from the pre-installed sprue. The positioning tray 22 is then installed on the support frame 21. The supporting component 2 is then pulled upwards again, causing the positioning protrusion 221 on the positioning tray 22 to engage with the sprue's outlet. 1. Align with the outlet positioning of the water inlet to fine-tune the installation position of the water inlet, ensuring the installation accuracy of the water inlet, and supporting the water inlet to rise again to the first preset height, so as to facilitate the removal of the separation ring. Then, apply fire putty to the corresponding positions of the separation ring, the seat brick, and the water inlet, and reinstall the separation ring between the outer wall of the water inlet and the inner wall of the seat brick, so that the supporting component 2 supports the water inlet to descend to the required height, ensuring that the separation ring secures the water inlet and the seat brick, and keeping the supporting component 2 at this height for a preset time to ensure that the fire putty cures, thereby completing the installation of the water inlet.

[0057] Optionally, in this embodiment, as Figure 3 and Figure 4 As shown, the support frame 21 has multiple positioning holes 21111 spaced apart, and the bottom of the positioning tray 22 has multiple insertion protrusions 222 spaced apart. Each insertion protrusion 222 corresponds to one of the positioning holes 21111, and the insertion protrusion 222 is inserted and fixed into the corresponding positioning hole 21111. This arrangement allows the support frame 21 and the positioning tray 22 to be detachably fixed via the insertion protrusions 222 and the positioning holes 21111, eliminating the need for tightening or screwing operations. This facilitates installation and disassembly, and the structure is simple, while also achieving the positioning installation of the positioning tray 22 on the support frame 21. Optionally, in this embodiment, the insertion protrusion 222 can be a positioning pin, which is welded to the positioning tray 22. In other embodiments, the insertion protrusion 222 is a boss directly protruding from the bottom of the positioning tray 22. Optionally, in this embodiment, four insertion protrusions 222 are spaced apart to ensure the stability of the insertion and fixing. In other embodiments, the specific number of insertion protrusions 222 can be set according to requirements.

[0058] In this embodiment, the positioning tray 22 is provided with a grip handle 223. By providing a grip handle 223, it is easy to grasp the positioning tray 22, place the positioning tray 22 on the support frame 21, or remove the positioning tray 22 from the support frame 21.

[0059] In this embodiment, as Figure 4 As shown, the support frame 21 includes a support plate 211 and a limiting frame 212. The support plate 211 includes a support base plate 2111 and a mounting side plate 2112 connected at an angle. The support base plate 2111 is used to support the water inlet and the positioning tray 22 can be detachably installed on the support base plate 2111. The water inlet is positioned and accommodated in the limiting frame 212. The limiting frame 212 includes a limiting stop bar 2121 and two connecting rods 2122. The two connecting rods 2122 are arranged at intervals along the left and right direction. The first ends of the two connecting rods 2122 are fixed to the mounting side plate 2112. The two ends of the limiting stop bar 2121 are detachably connected to the second ends of the two connecting rods 2122 respectively. The structural design of the aforementioned support frame 21 allows for the following steps when supporting the water inlet: First, the limiting stop 2121 is detached from the two connecting rods 2122. Then, the water inlet is placed between the two connecting rods 2122, with the support base plate 2111 supporting it. Finally, the limiting stop 2121 is installed on the two connecting rods 2122, thus achieving the support and positioning of the water inlet and preventing any impact to the water inlet during placement. Optionally, in this embodiment, the support base plate 2111 has multiple positioning holes 21111 spaced apart. Optionally, both ends of the limiting stop 2121 are detachably connected to the second ends of the two connecting rods 2122 by bolts.

[0060] Optionally, in this embodiment, as Figure 4 As shown, the support plate 211 also includes a reinforcing rib 2113, which connects the support base plate 2111 and the mounting side plate 2112. By setting the reinforcing rib 2113, the structural strength of the entire support plate 211 is effectively guaranteed.

[0061] In this embodiment, as Figure 4 As shown, the support frame 21 also includes a mounting frame 213, which is connected to the mounting side plate 2112, and the traction rope 33 is internally connected to the mounting frame 213. This configuration avoids interference between the traction rope 33 and the sprue supported by the support plate 211, ensuring the reliability of the traction rope 33 in pulling the support frame 21 and raising / lowering the sprue.

[0062] To facilitate understanding of the sprue-assisted installation vehicle disclosed in this embodiment, it is now combined with Figures 1-4 The following describes the specific installation process of the sprue using the sprue auxiliary installation vehicle:

[0063] First, the sprue is moved to the sprue auxiliary installation vehicle and elastically fixed to the installation plate 112 by the elastic element. Then, the sprue is placed on the support base plate 2111 and the limit stop bar 2121 is installed on the two connecting rods 2122. Then, the elastic element on the sprue is removed.

[0064] Next, the sprue auxiliary installation vehicle is moved to the bottom of the intermediate tundish, and the vehicle body 1 is lifted by a forklift so that the top of the vehicle body frame 11 can be detachably fixed to the bottom of the intermediate tundish.

[0065] Then, the seat bricks inside the intermediate package are installed and positioned;

[0066] Next, rotate the drive handle 34 to raise the support frame 21 to the first preset height. Then, install a separation ring between the outer wall of the sprue and the inner wall of the seat brick. The sprue is pre-installed on the seat brick of the tundish through the separation ring. Then, lower the support frame 21 to separate the support frame 21 from the pre-installed sprue.

[0067] Then, the positioning tray 22 is installed on the support frame 21, and the bearing component 2 is pulled up again so that the positioning protrusion 221 on the positioning tray 22 is positioned and engaged with the outlet of the water nozzle, thereby fine-tuning the installation position of the water nozzle, ensuring the installation accuracy of the water nozzle, and supporting the water nozzle to rise again to the first preset height so that the separation ring can be removed. Then, fire clay is applied to the corresponding positions of the separation ring, the seat brick and the water nozzle, and the separation ring is reinstalled between the outer wall of the water nozzle and the inner wall of the seat brick.

[0068] Next, the support component 2 is lowered to the required height to ensure that the separation ring secures the water inlet and the seat brick. Then, the support component 2 is held at this height for a preset time to ensure that the fire clay solidifies.

[0069] After the fire clay has solidified, the top of the vehicle frame 11 is separated from the bottom of the intermediate tundish. The vehicle frame 11 is then lowered using a forklift, making it easier to push the entire unloaded vehicle body 1 out from the bottom of the intermediate tundish to complete the installation of the sprue.
