Description

Technical Field

[0001] The utility model relates to the technical field of casting transportation, in particular to a safety steel vehicle used in a casting workshop. Background Art

[0002] A foundry is a place where metal is heated and melted and poured into pre-made sand molds or moulds, and then cooled and solidified into the required objects (parts). The steel cars used in the foundry are usually used to transport ladles of molten steel.

[0003] However, the prior art has the following defects:

[0004] When placing the ladle on a steel car for transportation, a clamping mechanism is required to fix the ladle in place to prevent it from tipping over during movement. However, it takes a long time to place the ladle on the steel car and then drive the clamping mechanism to clamp it, resulting in low transportation efficiency. Utility Model Content

[0005] In order to solve the technical problem of low efficiency in clamping and transporting a molten steel ladle, the utility model provides a safety steel cart for a foundry.

[0006] The utility model is implemented by the following technical scheme: a safety steel car for a foundry comprises a car body and wheels, four of the wheels are arranged below the car body, and a limiting mechanism is arranged above the car body; the limiting mechanism comprises a steel ladle, an upper groove, a middle groove, a spring, a placement plate and a limiting unit, the upper groove is arranged on the car body, the middle groove is arranged in the middle of the upper groove, two clamping arc plates are arranged in the middle groove through the limiting unit, one end of the four springs are welded in the upper groove, and the other end of the springs are welded to one end of the placement plate, and the other end of the placement plate can place the steel ladle.

[0007] Through the above technical solution, the four springs can drive the placement plate back to its original position when the placement plate is not subjected to the pressure of the ladle, separate the two clamping arc plates and the two protection plates, and then the ladle can be away from the car body for subsequent pouring operations. In addition, the car body is made of hard steel, which is not easy to deform and can be used for a long time.

[0008] As a further improvement of the above scheme, the limiting unit includes a sliding unit and a pull-down unit, the sliding unit includes a slide rail and a slider, the two slide rails are symmetrically opened on the inner wall of the middle groove, and the two ends of the slider extend into the slide rail to slide, and the clamping arc plate and the slider are fixedly connected.

[0009] Through the above technical solution, the two clamping arc plates can be driven to approach each other and fit on the ladle by pulling the slider, and the two ends of the slider slide in the slide rail, which also increases the smoothness of the slider when moving. At the same time, the clamping arc plate is set to an arc shape, which can better fit the ladle, making the ladle limit more stable.

[0010] As a further improvement of the above scheme, the pull-down unit includes a hinged rod and a pressing plate, one end of the hinged rod is hinged on the slider, and the other end of the hinged rod is hinged on the pressing plate, and a movable groove for allowing the pressing plate to move up and down is opened in the middle of the middle groove, and the pressing plate is fixed on the placement plate and located in the middle of the four springs.

[0011] Through the above technical solution, by hingedly connecting the hinged rod and the pressing plate, when the placing plate forces the pressing plate to move into the lower groove, the hinged rod can be pulled to move from the middle groove to the lower groove, and then the two clamping arc plates are driven to fit the ladle for clamping operation.

[0012] The movable groove allows the pressing plate to move up and down more smoothly, and the movable groove will penetrate so that one end is located outside the car body, and the width of the middle groove and the lower groove is upper groove>lower groove>middle groove, which can avoid the situation where the car body is flattened by the molten steel ladle due to too many grooves in the car body.

[0013] As a further improvement of the above scheme, a protective mechanism is also movable in the upper groove, and the protective mechanism includes a lower groove, rack 1, a gear set, rack 2, a protective plate and a movable unit. The lower groove is opened in the vehicle body below the middle groove, the two racks 1 are fixed on the pressing plate below the hinged rod, and the gear set is arranged in the lower groove, and the rack 1 and the gear set constitute an engaging connection structure, one end of the rack 2 and the gear set also constitute an engaging connection structure, the other end of the rack 2 passes through the middle groove, is located in the upper groove and is connected to one end of the protective plate, and the other ends of the two protective plates can be close to each other.

[0014] Through the above technical solution, rack one includes a rotating rod, a gear and a belt. The two ends of the three rotating rods are fixed in the lower groove through bearings, and the gears are fixed on the rotating rods. The two rotating rods are linked by a belt to ensure that when rack one moves downward, the two racks two approach each other, and when rack one moves upward, the two racks two move away from each other.

[0015] Moreover, the tooth modules of the two gears close to the rack 1 are different, which can ensure that the moving distance of the rack 1 is much smaller than the moving distance of the two protective plates, thereby ensuring that the ladle can be easily moved out of the clamping arc plate without being affected.

[0016] As a further improvement of the above solution, the moving unit includes a hemispherical block and a slideway, two of the slideways are opened in the lower groove, the hemispherical block is fixed on the second rack, and the hemispherical block slides in the slideway.

[0017] Through the above technical solution, the hemispherical block slides on the slideway, so that the rack 2 can move more smoothly and stably.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The utility model can clamp the ladle by placing it on the vehicle body under the action of the limit mechanism, thus saving the time of workers starting the clamp mechanism. In addition, the ladle can be directly protected with the cooperation of the protection mechanism, which can keep the heat and enhance the safety. BRIEF DESCRIPTION OF THE DRAWINGS

The upper groove 4 is opened on the car body 1, the middle groove 5 is opened in the middle of the upper groove 4, two clamping arc plates 11 are arranged in the middle groove 5 through the limiting unit, one end of the four springs 7 are welded in the upper groove 4, and the other end of the spring 7 is welded to one end of the placement plate 8, and the other end of the placement plate 8 can place the ladle 3.

[0029] The limiting unit includes a sliding unit and a pull-down unit. The sliding unit includes a slide rail 9 and a slider 10. The two slide rails 9 are symmetrically opened on the inner wall of the middle groove 5, and both ends of the slider 10 extend into the slide rail 9 to slide. The clamping arc plate 11 and the slider 10 are fixedly connected.

[0030] The pull-down unit includes a hinged rod 12 and a pressing plate 13. One end of the hinged rod 12 is hinged on the slider 10, and the other end of the hinged rod 12 is hinged on the pressing plate 13. A movable groove is opened in the middle of the middle groove 5 for the pressing plate 13 to move up and down. The pressing plate 13 is fixed on the placement plate 8 and is located between the four springs 7.

[0031] The working principle of the safety steel car used in the foundry of the present application is as follows: after the ladle 3 is filled with molten steel, the car body 1 is lifted by a crane and placed in the middle of the placement plate 8. The ladle 3 will contact the placement plate 8, and the placement plate 8 will be pressed into the upper groove 4 under the action of gravity potential energy. The four springs 7 are compressed, driving the pressing plate 13 to go deeper into the lower groove 6, and the two hinged rods 12 are pulled into the lower groove 6. The slider 10 slides in the slide rail 9 in the direction of the spring 7, driving the two clamping arc plates 11 to approach the ladle 3. When the pressing plate 13 moves into the lower groove 6, The rack 1 14 is also driven to move downward, and the gear set 15 is driven to rotate under the meshing connection between the rack 14 and the gear set 15. Under the meshing action of the gear set 15 and the rack 2 16, the two racks 2 16 are brought closer to each other, driving the two guard plates 19 to approach each other, and the hemispherical block 17 also slides in the direction of the spring 7 in the slideway 18. When the ladle 3 presses the placement plate 8 to the maximum extent, the two clamping arc plates 11 fit on the ladle 3 to clamp it, and the two guard plates 19 are about to fit to block the top of the car body 1. At this time, the suspension rope is removed from the hanging ears on both sides of the ladle 3, and the power supply on the side of the driving wheel 2 is turned to rotate the wheel 2, and the car body 1 drives the ladle 3 to move.

[0032] When the vehicle body 1 drives the ladle 3 to the designated place, the lifting rope is hung on the hanging ears on both sides of the ladle 3, and the ladle 3 is lifted. Under the rebound potential energy of the spring 7, the pressing plate 13 can be pulled away from the lower groove 6 gradually, so that the two clamping arc plates 11 are away from each other, and the two protective plates 19 are also away from each other, so that the ladle 3 is away from the vehicle body 1 for pouring.
