In actual use, the guardrail is prone to falling off, resulting in low safety. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, the structure of the ladle trolley varies depending on the usage requirements. The ladle trolley is also equipped with a heat preservation tank to store materials such as ladles and molten steel. Workbenches need to be installed on both sides of the heat preservation tank for subsequent operations. However, the guardrails on the workbenches are installed by plugging in, and the gap between the bottom of the guardrail and the slot is large. In actual use, the guardrail is prone to falling off, resulting in low safety. Therefore, this utility model proposes a ladle trolley with a built-in heat preservation tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel ladle trolley with a built-in insulated tank, comprising a vehicle body mechanism, the vehicle body mechanism comprising an insulated tank, a movable base fixedly connected to the outer surface of the insulated tank, a support frame fixedly connected to the upper end of the movable base, an operating frame fixedly connected to the upper end of the support frame, a protective railing reinforcement mechanism provided on the outer surface of the operating frame, the protective railing reinforcement mechanism comprising an assembly block, the assembly block being fixedly connected to the operating frame, an assembly cavity being opened at the upper end of the assembly block, a sliding cavity being opened on one side of the assembly block, a pressing block and a side pressure plate being slidably connected inside the sliding cavity, a spring being fixedly connected between the side pressure plate and the pressing block, and a limiting tooth being fixedly connected to one side of the pressing block.

[0007] Preferably, a side sealing plate is fixedly connected to one side of the assembly block, and a threaded hole is provided through the middle of the side sealing plate.

[0008] Preferably, the internal thread of the threaded hole is connected to an adjusting bolt, one end of which contacts the side pressure plate.

[0009] Preferably, a movable component is installed at the lower end of the movable base.

[0010] Preferably, a side support is rotatably connected to the lower end of the movable base and to one side of the movable component.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a spring and limiting teeth, when installing the guardrail, the guardrail pins are inserted into the assembly cavity, and the limiting teeth engage with the slots. The spring pushes the pressing block, thereby pressing the pins. This increases the connection area and compresses the pins, increasing connection stability, preventing pin movement and detachment, and ensuring stable use. The structure is relatively simple and has low operating costs. At the same time, this method still uses a plug-in installation method, making the connection convenient and quick. The side sealing plate allows for easy removal and installation of the pressing block area. Different shaped limiting teeth can be used depending on the shape of the slot on the guardrail pin.

[0012] 2. In this utility model, the adjustment bolt is used to apply force to the side pressure plate, thereby moving the side pressure plate. In this way, the adjustment bolt can be removed or its end can be placed inside the threaded hole during installation. This reduces the spring's thrust on the compression block, facilitating the installation of the guardrail pin. After the pin is inserted, the side pressure plate can be moved by rotating the adjustment bolt, causing the spring to be compressed. This makes the connection between the limiting tooth and the pin more stable, preventing the guardrail from moving and further improving its stability in use. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a steel ladle trolley with a built-in insulated tank, including a vehicle body mechanism 1. The vehicle body mechanism 1 includes an insulated tank 11. A movable base 12 is fixedly connected to the outer surface of the insulated tank 11. A support frame 14 is fixedly connected to the upper end of the movable base 12. An operating frame 15 is fixedly connected to the upper end of the support frame 14. A guardrail reinforcement mechanism 2 is provided on the outer surface of the operating frame 15. The guardrail reinforcement mechanism 2 includes an assembly block 21. The assembly block 21 is fixedly connected to the operating frame 15. An assembly cavity 24 is opened at the upper end of the assembly block 21. A sliding cavity 28 is opened on one side of the assembly block 21. A pressing block 210 and a side pressure plate 26 are slidably connected inside the sliding cavity 28. A spring 27 is fixedly connected between the side pressure plate 26 and the pressing block 210. A limiting tooth 25 is fixedly connected to one side of the pressing block 210. The outer surface of the guardrail insert needs to be provided with a groove that engages with the limiting tooth 25.

[0018] The specific settings and functions of this embodiment are described in detail below. Through the arrangement of the spring 27 and the limiting teeth 25, when installing the guardrail, the guardrail pins are inserted into the assembly cavity 24, and the limiting teeth 25 engage with the slots. The spring 27 pushes the pressing block 210, thereby pressing the pins. This increases the connection area and compresses the pins, increasing connection stability, preventing pin movement and detachment, and ensuring operational stability. Furthermore, this structure is relatively simple and has low operating costs. This method still uses a plug-in installation, making connection convenient and quick. The side sealing plate 22 allows for easy replacement of the limiting teeth 25 with different shapes depending on the slot shape on the guardrail pin, facilitating the removal and installation of the pressing block 210.

[0019] Example 2: Figure 1 - Figure 4 As shown, a side sealing plate 22 is fixedly connected to one side of the assembly block 21. A threaded hole 29 is opened through the middle of the side sealing plate 22. An adjusting bolt 23 is threaded inside the threaded hole 29. One end of the adjusting bolt 23 contacts the side pressure plate 26. A moving component 13 is installed at the lower end of the moving base 12. A side support 16 is rotatably connected to the lower end of the moving base 12 and on one side of the moving component 13.

[0020] The overall effect of this embodiment is that by adjusting the setting of the bolt 23, force is applied to the side pressure plate 26, thereby moving the side pressure plate 26. In this way, the adjusting bolt 23 can be removed during installation or its end can be located inside the threaded hole 29. This reduces the thrust of the spring 27 on the pressing block 210, facilitating the installation of the guardrail pin. After the pin is inserted, the side pressure plate 26 can be moved by rotating the adjusting bolt 23, causing the spring 27 to be compressed. This makes the connection between the limiting tooth 25 and the pin more stable, preventing the guardrail from moving and further improving the stability of use.

[0021] The usage and working principle of this device are as follows: When installing the guardrail, the side of the guardrail with the groove at the insertion point faces the limiting tooth 25. Insert the insertion point of the guardrail into the assembly cavity 24. By squeezing, the limiting tooth 25 is retracted into the sliding cavity 28. The elasticity of the spring 27 pushes the squeezing block 210 to move, so that the groove and the limiting tooth 25 are engaged. When the insertion point is inserted to the bottom, the installation is complete. After installation, the position of the side pressure plate 26 can be adjusted by rotating the adjusting bolt 23 according to actual needs. This will cause the spring 27 to deform and apply greater force to the squeezing block 210, ensuring the stability of the assembly. In use, connect the wheel of the moving component 13 to the guide roller. The moving component 13 drives the moving base 12 to move, placing the steel ladle or molten steel to be transported into the insulated tank 11 for transportation.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
