Description

Technical Field

[0001] This utility model relates to the field of molten steel ladle transportation technology, and in particular to a positioning device for a molten steel ladle transport vehicle. Background Technology

[0002] In the metallurgical industry, molten steel ladles (steel ladles, steel ladles) are key equipment used for holding, transporting and pouring high-temperature molten steel (or molten iron). In the nickel smelting process, the molten material discharged from the electric furnace needs to be discharged into the liquid steel ladle, and the ladle needs to be transported by vehicle. During the transportation of molten steel ladles by vehicle, accurate monitoring of the vehicle's position and movement information is crucial for production management and safety control.

[0003] A search revealed Chinese Patent Publication No. CN202020780435.3, which includes a flatbed cart. The flatbed cart has a support plate on its top, and adjusting rods are hinged to the left and right sides of the bottom of the support plate. Adjusting grooves are also provided on the left and right sides of the top of the flatbed cart. This utility model utilizes a connecting plate to support a supporting spring, and the flatbed cart is supported by the spring. A measuring rod is installed on the top of the left-side support slider, allowing the measuring rod to accurately measure the weight of the molten steel inside the ladle based on the distance it moves. This makes the device quick and convenient for weighing the molten steel, and the device has relatively good shock absorption, resulting in strong vibration damping during transportation. This prevents molten steel from splashing during transport, ultimately achieving the goal of minimizing splashing and spillage during transportation, thus enhancing the device's safety. However, the ladle clamping in this application is manually set, and the two sides cannot be driven synchronously, affecting the clamping effect and limiting its use. Utility Model Content

[0012] Preferably, a clamping plate is fixedly connected to the top of the positioning block, and three sets of clamping plates are provided. The clamping plates are symmetrically arranged on the top of the positioning blocks at both ends and one side.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes connecting rods to drive corresponding positioning blocks. The connecting rods are arranged in a circular array on the outside of a synchronous plate. The synchronous plate is rotatably connected to a positioning platform. A drive motor is connected to the synchronous plate via a drive shaft, driving the synchronous plate to rotate. The synchronous plate is connected to a movable block via connecting rods and a rotating shaft. The movable block is positioned within a sliding groove on the top of the placement platform, and the size of the movable block matches the size of the sliding groove. The sliding groove limits the movement of the movable block, allowing it to move within the groove. Thus, when the synchronous plate drives multiple sets of connecting rods, it synchronously drives the positioning blocks on top of the corresponding movable blocks to move, thereby changing the distance between the positioning blocks and accommodating the clamping, fixing, or loosening of molten steel ladles of different sizes.

[0015] This utility model features a clamping plate fixedly connected to the top of a positioning block. Three sets of clamping plates are provided, symmetrically positioned at the top of the positioning blocks at both ends and one side. An auxiliary support block is provided on the outer side of the clamping plate, with its bottom end abutting against the surface of the placement platform. The clamping plates assist in clamping the molten steel ladle, and the symmetrical clamping plates on the outer auxiliary support blocks provide support to improve stability. The clamping plates at both ends and one side ensure the stability of the support while facilitating the lifting and placement of the molten steel ladle from one side. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] refer to Figures 1 to 6 A positioning device for a molten steel ladle transport vehicle includes: a device base 1, a drive wheel 2 provided on the outer side of the bottom end of the device base 1, a placement platform 3 fixedly provided on the top of the device base 1, and a positioning platform 4 provided on the top of the placement platform 3.

[0025] A positioning block 5 is provided on the outer side of the positioning platform 4. An auxiliary support plate 6 is fixedly connected to the top of the positioning block 5. A molten steel ladle 7 is provided on the top of the positioning platform 4. A drive assembly 8 is provided at the bottom of the positioning platform 4. A drive motor 9 is provided at the bottom of the drive assembly 8.

[0026] Specifically, the number of positioning blocks 5 is set to four groups, the positioning blocks 5 are distributed in a circular array, and the positioning blocks 5 are arranged in an arc shape.

[0027] Specifically, the drive assembly 8 includes a movable block 801 fixedly connected to the bottom of the positioning block 5. One end of the movable block 801 is connected to a connecting rod 802 via a rotating shaft. One end of the connecting rod 802 is connected to a synchronization plate 803 via a rotating shaft. The number of connecting rods 802 is set to four sets, and the connecting rods 802 are distributed in a ring array on the outside of the synchronization plate 803.

[0028] Specifically, the synchronization plate 803 is rotatably connected to the positioning stage 4, and the drive motor 9 is drive-connected to the synchronization plate 803.

[0029] Specifically, the top of the placement platform 3 is provided with a sliding groove 301, and the movable block 801 is adapted to the size of the sliding groove 301. The movable block 801 is slidably connected to the placement platform 3 through the sliding groove 301.

[0030] Specifically, the synchronization plate 803 is connected to the movable block 801 via a connecting rod 802.

[0031] Specifically, a clamping plate 501 is fixedly connected to the top of the positioning block 5. There are three sets of clamping plates 501. The clamping plates 501 are symmetrically arranged at the top of the positioning blocks 5 at both ends and one side. An auxiliary support block 502 is provided on the outside of the clamping plate 501. The bottom end of the auxiliary support block 502 abuts against the surface of the placement platform 3.

[0032] In this embodiment, to meet different positioning and fixing requirements of molten steel ladles, a positioning block 5 is fixedly connected to one end of a movable block 801 at its bottom. The other end of the movable block 801 is connected to one end of a connecting rod 802 via a rotating shaft. The other end of the connecting rod 802 is connected to a synchronization plate 803 via a rotating shaft. Four sets of connecting rods 802 are correspondingly arranged with the positioning blocks 5. The connecting rods 802 drive the corresponding positioning blocks 5. The connecting rods 802 are arranged in a circular array on the outside of the synchronization plate 803. The synchronization plate 803 is rotatably connected to the positioning table 4. The drive motor 9 is connected to the synchronization plate 803 via a drive shaft. The drive motor 9 drives the synchronization plate 803. The plate 803 rotates, and the synchronous plate 803 is connected to the movable block 801 through the connecting rod 802 and the rotating shaft. The movable block 801 is set in the sliding groove 301 on the top of the placement platform 3, and the size of the movable block 801 is adapted to the sliding groove 301. The sliding groove 301 limits the movable block 801, so that it moves within the sliding groove 301. Thus, when the synchronous plate 803 drives multiple sets of connecting rods, it synchronously drives the positioning block 5 on the top of the corresponding movable block 801 to move, so that the positioning block 5 moves synchronously to change the distance between the positioning blocks 5, which can be used to clamp and fix or release molten steel ladles 7 of different sizes.

[0033] It should be noted that a clamping plate 501 is fixedly connected to the top of the positioning block 5. There are three sets of clamping plates 501. The clamping plates 501 are symmetrically arranged on the top of the positioning blocks 5 at both ends and one side. An auxiliary support block 502 is provided on the outside of the clamping plate 501. The bottom end of the auxiliary support block 502 abuts against the surface of the placement platform 3. The molten steel ladle 7 is assisted in being clamped by the clamping plate 501. The outer auxiliary support block 502 symmetrically clamps the plate 501 to improve stability. The clamping plates 501 at both ends and one side ensure the stability of the support while facilitating the lifting and insertion of the molten steel ladle 7 from one side.

[0034] Based on the above embodiments, in use, the device is moved to the desired position by the drive wheel 2 (with a common drive component installed on the inner side of the drive wheel 2, which is a conventional known technical means). The molten steel ladle 7 is placed on the positioning platform 4 by hoisting. The drive motor 9 drives the synchronous plate 803 to rotate through the transmission shaft. The rotation of the synchronous plate 803 drives the four sets of connecting rods 802 to move synchronously through the rotating shaft. The movement of the four sets of connecting rods 802 drives the corresponding movable blocks 801 to move in the sliding groove 301 opened at the top of the placement platform 3 through the rotating shaft. The synchronous movement of the four sets of movable blocks 801 drives the positioning block 5 at the top to move inward synchronously. The positioning block 5 clamps and fixes the bottom of the molten steel ladle 7. At the same time, the clamping plates 501 at both ends and one side assist in clamping the molten steel ladle 7. The outer auxiliary support block 502 symmetrically clamps the plate 501 to support and improve stability.
