Cart frame; 3. Driving motor; 4. Driving gear; 5. Buffer assembly; 6. Proximity switch. DETAILED DESCRIPTION

[0015] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings.

[0016] Embodiment 1: Figure 1 The schematic diagram of the structure of the hot box electric trolley provided in this embodiment. The device includes a box moving guide rail 1, a trolley frame 2 and a trolley drive assembly. Among them, the material receiving box for loading liquid high-temperature slag moves along the box moving guide rail 1. The trolley frame 2 is driven by the trolley drive assembly to push the material receiving box to move to realize the material receiving operation.

[0017] Specifically, the box moving guide rail 1 includes two parallel guide rails. The spacing between the two guide rails is slightly larger than the width of the material receiving box. When the material receiving box is located in the box moving guide rail 1, the two guide rails are respectively located on both sides of the material receiving box, and can limit the two sides of the material receiving box, thereby realizing the guidance of the material receiving box.

[0018] The cart frame 2 is arranged on the box moving guide rail 1 , and the cart frame 2 is slidably arranged on the box moving guide rail 1 .

[0019] The trolley driving assembly is used to drive the trolley frame 2 to move along the box moving guide rail 1. The trolley driving assembly includes a driving motor 3 fixedly mounted on the trolley frame 2, and a driving gear 4 is fixedly connected to the rotating shaft of the driving motor 3. Correspondingly, a transmission rack adapted to the driving gear 4 is fixedly mounted on the box moving guide rail 1, and the transmission rack extends along the length direction of the box moving guide rail 1. The driving gear 4 is meshed with the transmission rack. When the driving motor 3 drives the driving gear 4 to rotate, the trolley frame 2 can be driven to move forward and backward along the box moving guide rail 1 through the meshing of the driving gear 4 and the transmission rack.

[0020] Preferably, a buffer assembly 5 is fixedly provided at one end of the cart frame 2 that contacts the material receiving box, see Figure 1 In this embodiment, the buffer assembly 5 includes a rubber pad fixedly mounted on the cart frame 2. When the cart frame 2 moves toward the material receiving box and contacts the material receiving box, the rubber pad will contact the material receiving box first. The rubber pad can absorb the impact force between the cart frame 2 and the material receiving box, thereby playing a buffering role for the cart frame 2 and the material receiving box, and preventing the cart frame 2 from being damaged by direct collision with the material receiving box.

[0021] In addition, a travel limit assembly is provided on the box moving guide rail 1. The travel limit assembly includes a proximity switch 6 fixedly mounted on the box moving guide rail 1, a sensing element fixedly mounted on the cart frame 2, and a controller connected to the drive motor 3. When the cart frame 2 moves along the box moving guide rail 1 under the drive of the cart drive assembly, and the sensing element on the cart frame 2 enters the sensing area of ​​the proximity switch 6, the proximity switch 6 generates a control signal and sends the control signal to the controller. After receiving the control signal, the controller immediately controls the drive motor 3 to stop running, so that the cart frame 2 stops at a predetermined position.

[0022] It should be noted that the location of the proximity switch 6 can be determined according to actual production requirements. In this embodiment, a plurality of proximity switches 6 are provided, and the plurality of proximity switches 6 are arranged in sequence along the length direction of the box moving guide rail 1 .

[0023] Embodiment 2: This embodiment provides a method for using a hot box electric cart, which is implemented based on the hot box electric cart provided in Embodiment 1. The method specifically includes the following steps: Step S101: Control the cart frame to move to an initial position.

[0024] Step S102: using a crane to lift an empty material receiving box onto the box moving guide rail and in front of the cart frame, controlling the cart frame to move, and pushing the material receiving box to move a distance of the box length.

[0025] Step S103: Repeat step S102 until five empty material receiving boxes are located in front of the cart frame, and the frontmost material receiving box is located at the slag receiving position.

[0026] Step S104: After the frontmost receiving box is filled with slag, the pusher frame is controlled to push all the receiving boxes to move until the next empty receiving box is located at the slag receiving position. At the same time, the receiving box filled with slag is hoisted to the designated location for storage by a crane.

[0027] Step S105: Control the pushcart frame to return to the initial position, and use a crane to lift an empty material receiving box onto the box moving guide rail and position it in front of the pushcart frame.

[0028] Step S106: Repeat the above steps S104 and S105.

[0029] The above method solves the problem of the entry and exit of the blast furnace liquid high-temperature slag receiving box, which not only greatly improves the slag transportation efficiency, but also reduces the labor intensity of operators. At the same time, it eliminates the safety hazards caused by high temperature and ensures the safety of operators.

[0030] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
