Description

Special lifting appliance for fan-shaped track

Technical Field

The utility model relates to a hoist, the fan-shaped track special lifting device who is used for hoisting fan-shaped section of conticaster specifically says so.

Background

As is known in the casting industry, a continuous casting machine sector production shop is generally divided into two levels, the upper level being used to produce each part of the continuous casting machine sector, and the lower level being used to assemble each part after production to obtain the continuous casting machine sector. This requires that the produced part of the upper layer be fed into the lower layer.

At present, the method of the prior art is to arrange an opening on a laminate on an upper layer, and firstly, a traveling crane on the upper layer is adopted to send a component to the ground on a lower layer through the opening; and then, transporting the parts to corresponding stations by adopting the lower layer travelling crane. This kind of mode all installs the driving in the upper and lower floor in the workshop of conticaster fan-shaped section, and the driving that needs is more, and moreover, upper strata driving needs to install on the plywood of upper strata, leads to the plywood of upper strata promptly to bear the pulling force that pressure also need bear the driving, and the external force that the plywood of upper strata bore is great, fragile, exists serious potential safety hazard.

The upper parts of the pin ear plates are obliquely arranged towards one side of the other pin ear plate, and the upper parts of the pin ear plates are provided with connecting holes.

By adopting the scheme, the method has the following advantages:

because the connecting arms are hinged between the adjacent ends of two adjacent supporting shafts of the special lifting appliance for the fan-shaped track, one of the supporting shafts rotates in a vertical plane along the axis of the other supporting shaft, the two ends of the uppermost supporting shaft are both fixed with pin ear plates extending upwards, the two ends of the lowermost supporting shaft are both hinged with connecting plates extending downwards, the connecting plates are both vertical to the supporting shafts, a hanging rod is fixed between the two connecting plates, two hooks are arranged on the hanging rod, the hooks comprise an upper clamping plate and a lower clamping plate which are arranged in parallel side by side, the hanging rod is positioned between the upper clamping plate and the lower clamping plate, the upper clamping plate is provided with a screw rod, the screw rod is fixed on the upper clamping plate, the lower clamping plate corresponding to the lower end of the screw rod is provided with a through hole, and the lower end of the screw rod passes through hole and extends to the lower clamping plate, an adjusting nut is arranged at the lower end of the screw rod, supporting rods are fixed at the bottom of the lower clamping plate, and bending rods are arranged at the lower ends of the supporting rods. During the use, fan-shaped track all is installed to the opening of the workshop upper strata plywood of fan-shaped section of conticaster and the station of the workshop lower floor of fan-shaped section of conticaster, links to each other the driving on hoist and the workshop upper strata of fan-shaped section of conticaster through the round pin otic placode. When the lifting mechanism works, a part to be lifted is firstly hung between the two bending rods; then, starting a travelling crane to put down the lifting appliance and the component from the opening of the upper layer plate, putting the lifting appliance into a corresponding rail according to the corresponding station of the component, and deforming the lifting appliance along the rail under the limitation of the rail to approach the corresponding station; and then, the crane continues to lower the lifting appliance, and the lifting appliance sends the part to a corresponding station along the track. The lifting appliance can finish lifting only by one travelling crane, and the required travelling cranes are fewer. And in addition, traveling cranes are not needed in the lower layer of the production workshop of the fan-shaped section of the continuous casting machine, so that the potential safety hazard of the fracture of the laminate of the lower layer is avoided.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the special lifting device for fan-shaped track of the present invention comprises less than two supporting shafts 1 horizontally arranged, and two adjacent supporting shafts 1 are all arranged side by side in parallel. The connecting arms 4 are hinged between the adjacent ends of the two adjacent supporting shafts 1, so that one supporting shaft 1 rotates in a vertical plane along the axis of the other supporting shaft; the two ends of the supporting shaft 1 at the top are fixed with pin ear plates 3 which extend upwards. All articulated on the both ends of one back shaft 1 of the bottommost have connecting plate 5 that stretches out downwards, and connecting plate 5 all is perpendicular with back shaft 1, is fixed with jib 6 between two connecting plates 5, has two couples on the jib 6. The couple includes parallel punch holder 9 and the lower plate 10 of arranging side by side, jib 6 is located between punch holder 9 and lower plate 10, and the both sides of punch holder 9 and lower plate 10 are stretched out from the both sides of jib 6 respectively, all has screw rod 11 that stretches out downwards on the outer extension of punch holder 9, and screw rod 11 is fixed on punch holder 9, has the through-hole on the lower plate 10 that the 11 lower extremes of screw rod correspond, and the 11 lower extremes of screw rod pass this through-hole and stretch out the 10 below of lower plate, is the sliding fit between through-hole and screw rod 11, has adjusting nut 12 on the 11 lower extremes of screw rod. The bottom of the lower splint 10 is fixed with a support rod 7, and the lower end of the support rod 7 is provided with a bending rod 8 which is bent by 90 degrees away from the other support rod 7.

The upper parts of the pin ear plates 3 are obliquely arranged towards one side of the other pin ear plate 3, and the upper parts of the pin ear plates 3 are provided with connecting holes 2.

During the use, fan-shaped track all is installed to the opening of the workshop upper strata plywood of the fan-shaped section of conticaster and the station of the workshop lower floor of the fan-shaped section of conticaster, links to each other the driving on hoist and the workshop upper strata of the fan-shaped section of conticaster through round pin otic placode 3. When in work, the part to be lifted is firstly hung between the two bending rods 8; then, starting a travelling crane to put down the lifting appliance and the component from the opening of the upper layer plate, putting the lifting appliance into a corresponding rail according to the corresponding station of the component, and deforming the lifting appliance along the rail under the limitation of the rail to approach the corresponding station; and then, the crane continues to lower the lifting appliance, and the lifting appliance sends the part to a corresponding station along the track. The lifting appliance can finish lifting only by one travelling crane, and the required travelling cranes are fewer. And in addition, traveling cranes are not needed in the lower layer of the production workshop of the fan-shaped section of the continuous casting machine, so that the potential safety hazard of the fracture of the laminate of the lower layer is avoided. The distance between the two hooks can be adjusted to adapt to parts with different lengths, so that the universality of the special lifting appliance for the fan-shaped track is stronger.
