[0023] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1 As shown, the present embodiment provides a ladle furnace slag transfer device (hereinafter referred to as the transfer device), the transfer device includes a vehicle body 1 and a walking wheel unit arranged on the vehicle body 1, and also includes a driving component and a guardrail component 5 for preventing the slag from falling. The guardrail component 5 includes a mounting bracket 51 fixed at both ends of the vehicle body 1 and a guardrail 52 slidably mounted on the mounting bracket 51. The driving component drives the connected guardrail 52 to drive the guardrail 52 to rise and fall to cooperate with the loading and unloading of the slag.

[0026] In this embodiment, the slag is loaded into one or more storage containers, which are then placed on the vehicle body 1 and surrounded by the guardrail 52 .

[0027] like Figure 2 and Figure 3 The driving assembly shown includes a screw rod 4 mounted on a mounting bracket 51 , and the screw rod 4 passes through the guardrail 52 and is threadedly connected to each other to ensure that the guardrail 52 is raised or lowered by rotating the screw rod 4 .

[0028] like Figure 1 As shown, there are two screw rods 4, which are respectively arranged on corresponding mounting brackets 51 and are symmetrically arranged in the front and rear. The two screw rods 4 are connected by a transmission belt 43, and the upper end of one of the screw rods 4 located on the rear side passes through the top of the corresponding mounting bracket 51 and is equipped with a handle 41 for the operator to easily rotate the screw rod 4.

[0029] By rotating the handle 41, the screw rod 4 on the left side is driven to rotate, and the transmission belt 43 is used to drive the two screw rods 4 to rotate synchronously, and then the threaded connection between the screw rod 4 and the guardrail 52 is used to drive the guardrail 52 to rise and fall, thereby realizing the height adjustment of the guardrail 52 according to needs, and the structure is simple and the operation is convenient.

[0030] When the transfer device needs to transfer slag or after the slag loading and unloading is completed, the driving assembly drives the guardrail 52 to rise, increasing the height of the guardrail 52 until the guardrail 52 rises to the protective height to enclose the slag.

[0031] When the transfer device needs to load and unload slag, the guardrail 52 is lowered to the lowest position or the lowest height through the driving assembly to facilitate the operator to load and unload the slag.

[0032] The guardrail assembly 5 is used to prevent the slag from falling, and the driving assembly is used to drive the guardrail 52 to rise and fall, so that the height of the guardrail 52 can be increased during transportation to enclose the slag and prevent it from falling, and the height of the guardrail 52 can be reduced during unloading to facilitate the loading and unloading of the slag.

[0033] In another preferred embodiment, Figure 1 As shown, a retractable protection rod 6 is provided between the vehicle body 1 and the protection rail 52 , one end of the protection rod 6 is hinged to the vehicle body 1 , and the other end is hinged to the protection rail 52 .

[0034] More specifically, Figure 2 The protective rod 6 shown includes a first rod body 61 and a second rod body 62 connected to each other, and a sliding connection is formed between the first rod body 61 and the second rod body 62 to form a retractable setting. The upper end of the first rod body 61 away from the second rod body 62 is hinged to the vehicle body 1, and the lower end of the second rod body 62 away from the first rod body 61 is hinged to the guardrail 52.

[0035] In a specific implementation, the guardrail 52 is slidably mounted on the mounting bracket 51 through a sliding sleeve 42 .

[0036] The lower end of the first rod body 61 can be slidably inserted into the upper end of the second rod body 62 to enable the first rod body 61 and the second rod body 62 to make corresponding up and down sliding under the action of external force, and when the height of the vehicle body 1 remains unchanged, the guardrail 52 follows the second rod body 62 to slide up and down synchronously to match the distance between the vehicle body 1 and the guardrail 52 or the height of the guardrail 52 in different usage states. At the same time, the guardrail 6 can also prevent slag from falling.

[0037] In another preferred embodiment, Figure 1 , Figure 2 and Figure 4As shown, the front and rear sides of the bottom of the vehicle body 1 are respectively provided with liftable support legs 7, as shown in FIG. Figure 3 The support leg 7 shown includes a connecting frame 71 slidably mounted on the vehicle body 1 and a supporting leg 72 connected to the connecting frame 71. A rotating shaft 73 is arranged between the connecting frame 71 and the screw rod 4. The bottom end of the screw rod 4 passes through the mounting bracket 51, the guardrail 52 and the vehicle body 1, and is then fixed with the rotating shaft 73. The rotating shaft 73 passes through the connecting frame 71 and is threadedly connected to each other, so that the support leg 7 can be raised and lowered.

[0038] More specifically, Figure 3 As shown, an elastic connection component 8 is arranged between the connecting frame 71 and the supporting foot 72. The elastic connection component 8 includes a guide limit rod 81 and a spring 82. The lower end of the guide limit rod 81 is fixed to the supporting foot 72, and the upper end of the guide limit rod 81 can be raised and lowered to pass through the connecting frame 71. The spring 82 is arranged between the supporting foot 72 and the connecting frame 71.

[0039] In this specific embodiment, a first limiting block is provided at the upper end of the guide limiting rod 81 passing through the connecting frame 71 to limit the connecting frame 71 and prevent the connecting frame 71 from escaping from the guide limiting rod 81 .

[0040] A second limit block is provided at one end of the rotating shaft 73 close to the supporting foot 72, and the second limit block is located between the supporting foot 72 and the connecting frame 71 to limit the moving distance of the rotating shaft 73 in the vertical direction and prevent it from being misaligned.

[0041] When the transfer device needs to load and unload slag, the handle 41 is turned forward to drive the screw rod 4 and the rotating shaft 73 to rotate synchronously, and the screw rod 4 and the guardrail 52 and the rotating shaft 73 and the connecting frame 71 are connected by threads to drive the guardrail 52 and the connecting frame 71 to move downward. At the same time, the connecting frame 71 compresses the spring 82 so that the spring 82 forms a downward elastic force and applies it to the support foot 72, thereby driving the support foot 72 to move downward until the support foot 72 contacts the ground to fix the vehicle body 1. At this time, the cooperation of the support foot frame 7 can effectively prevent the vehicle body 1 from accidentally moving during the loading and unloading of slag, so as to avoid affecting the loading and unloading of slag. In addition, when the support foot 72 contacts the ground and the guardrail 52 has not dropped to the lowest position, the handle 41 is continued to be turned to drive the guardrail 52 to move downward, but because both ends of the rotating shaft 73 are not provided with external threads, the support foot 72 will not continue to move downward synchronously, and only the guardrail 52 can continue to move downward to the lowest position.

[0042] When the transfer device is finished loading and unloading slag or needs to transfer slag, the handle 41 is rotated in the opposite direction to drive the screw rod 4 and the rotating shaft 73 to rotate in the opposite direction synchronously, so as to drive the guardrail 52 and the connecting frame 71 to rise, and under the upward elastic force of the spring 82, the support foot 72 is pulled up, moved and away from the ground to ensure that the vehicle body 1 can move or pull normally again. In addition, when the support foot 72 is away from the ground and the guardrail 52 has not risen to the protection height, but because both ends of the rotating shaft 73 are not provided with external threads, the support foot 72 will not continue to move upward synchronously and will be pulled by the spring 82 to remain motionless.

[0043] In another preferred embodiment, Figure 1 and Figure 4 As shown, a pull rod assembly 9 is provided at the front end of the vehicle body 1, and the pull rod assembly 9 includes a fixing frame 91 fixed on the vehicle body 1, a steering shaft 92 rotatably mounted on the fixing frame 91, and a pull rod 93 fixed on the steering shaft 92. The running wheel unit includes a front running wheel 2 and a rear running wheel 3. The front running wheel 2 is mounted on the bottom of the steering shaft 92 facing the ground, and the rear running wheel 3 is mounted on the rear side of the vehicle body 1 away from the pull rod assembly 9, so as to ensure that the transfer device can turn and move under the action of external force.

[0044] When the transfer device needs to be transferred to another location, the steering shaft 92 is pulled forward by the pull rod 93 to drive the vehicle body 1 to move forward and drive the front running wheels 2 and the rear running wheels 3 to rotate. At the same time, the pull rod 93 drives the steering shaft 92 to rotate so that the front running wheels 2 turn accordingly, so as to realize the overall steering of the vehicle body 1, thereby improving the ease of use of the transfer device.

[0045] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
