Description

Technical Field

[0001] This utility model relates to the field of converter bridge technology, and in particular to a bridge for changing the slide plate in a converter. Background Technology

[0002] In the iron and steel metallurgical industry, the converter tapping spout and the converter sliding plate slag-blocking mechanism are the only channels for molten steel to enter the ladle for the next process. The sliding plate slag-blocking mechanism used in the converter is to prevent slag from the furnace from entering the ladle and affecting the composition of the molten steel. During the tapping process, the tapping spout and the converter sliding plate slag-blocking mechanism must withstand the friction, scouring and oxidation of high-temperature molten steel and slag, resulting in a very short service life for the tapping spout and the converter sliding plate slag-blocking mechanism, which need to be replaced from time to time.

[0003] An operating platform for changing the tapping spout and sliding plate mechanism in a converter, with publication number CN220619001U, includes a steel frame structure. A protective canopy is fixed to the top of the steel frame structure, and an electric hoist travel track is installed below the canopy. Protective railings are welded around the steel frame structure. A distribution box and an electric hoist controller are also fixed to the steel frame structure. The distribution box is electrically connected to the electric hoist, and a distribution box socket is provided on the distribution box. The electric hoist controller is electrically connected to the electric hoist. A bridge base is fixed to the bottom of the steel frame structure.

[0004] Although this device reduces the labor intensity of workers during the disassembly and assembly of the steel outlet and the slag-blocking mechanism through accessories such as electric hoists and improves operational safety, during use, the control cable will move along with the electric hoist. During this movement, the cable may rub against the structural frame or get stuck, which may cause friction damage to the cable, resulting in exposed wire cores or cable breakage, thus posing certain safety hazards during use. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art where, during the movement of the electric hoist, the control cable moves along with it.

[0008] In a preferred embodiment, the protective canopy is provided with a reinforcing mechanism, which includes multiple sets of vertically staggered straight beams to improve the impact resistance of the protective canopy and enhance its safety protection capabilities.

[0009] In a preferred embodiment, guardrails are fixedly connected between the supporting columns on the same side to prevent workers from falling.

[0010] In a preferred embodiment, multiple guardrail reinforcing ribs are fixedly connected between the guardrail and the bridge base to improve the guardrail's stability and increase the safety factor.

[0011] In a preferred embodiment, mounting cavities are provided at both the front and rear corners of the bridge base. A rotating shaft is rotatably mounted in the mounting cavity, and a movable wheel is mounted at the lower end of the rotating shaft. The movable wheel facilitates the movement of the device on the ground and to a designated position. During hoisting, the movable wheel can be retracted by rotating the rotating shaft, which also facilitates hoisting and movement.

[0012] In a preferred embodiment, each side end of the bridge base is fixedly connected to a mounting box corresponding to the pivot. The end of the pivot extends through the mounting box and is fixedly connected to a worm gear. A worm is rotatably connected inside the mounting box. The worm and the worm gear are meshed and connected for transmission. By setting the worm to drive the worm gear, the worm and worm gear have self-locking properties, making the adjustment more stable.

[0013] In a preferred embodiment, a handle is fixedly connected to the top of the worm gear, making the rotation drive of the worm gear more stable.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model can protect the electrical cable through the suspension ring. When the electric hoist moves, the suspension ring will move with it to protect the cable, making the cable movement trajectory stable, preventing the cable from being damaged by friction, and improving the safety during use.

[0016] 2. This utility model allows the device to be moved on the ground easily via the movable wheels, making it convenient to move to a designated position. During hoisting, the movable wheels can be retracted by rotating the shaft, which also facilitates hoisting and movement.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a bridge for changing the slide plate of a converter, including a bridge base 1, with supporting columns 2 fixedly connected to the four corners of the bridge base 1, a protective canopy 3 fixedly connected to the top of the supporting columns 2, an installation beam 5 fixedly connected to the middle of the protective canopy 3, an I-shaped block 24 fixedly connected to the lower end of the installation beam 5, a moving mechanism slidably connected to the I-shaped block 24, an electric hoist 7 fixedly connected to the lower end of the moving mechanism, a hook 8 installed at the connecting end of the electric hoist 7, connecting frames 25 fixedly connected to both ends of the long side of the installation beam 5, a guide rod 6 fixedly connected between the two connecting frames 25, a hanging ring 26 slidably connected to the guide rod 6, and an electrical cable passing through the hanging ring 26. The hanging ring 26 can protect the electrical cable. When the electric hoist 7 moves, the hanging ring 26 moves accordingly to protect the cable, making the cable movement trajectory stable, preventing the cable from being damaged by friction, and improving safety during use.

[0026] like Figure 1-5 As shown, the moving mechanism includes two U-shaped blocks 10 slidably connected to the outer periphery of the I-shaped block 24. An installation block 12 is provided between the U-shaped blocks 10 for fixed connection. The electric hoist 7 is fixedly connected to the lower end of the installation block 12. A rotating wheel 11 is rotatably connected inside the U-shaped block 10. The lower end of the rotating wheel 11 abuts against the upper end of the bottom end of the I-shaped block 24. A drive motor 9 is fixedly installed on the outer periphery of the rotating wheel 11 to drive the rotating wheel 11 to rotate. A hanging wire frame 13 is fixedly installed on the top of one of the U-shaped blocks 10. The hanging wire frame 13 is slidably connected to the wire rod 6. By setting up the moving mechanism, the electric hoist 7 can be driven to slide horizontally on the I-shaped block 24, thereby moving the sliding plate.

[0027] like Figure 1-5As shown, a reinforcing mechanism 4 is installed inside the protective canopy 3. The reinforcing mechanism 4 includes multiple sets of vertically staggered straight beams, which are used to improve the impact resistance of the protective canopy 3 and enhance its safety protection capabilities.
