Abstract

The utility model discloses a tool for replacing and transporting large components in a rolling mill, belonging to the field of machinery. The utility model aims at providing a tool for replacing and transporting the large components in the rolling mill, which is capable of freely walking on the rolling mill and finishing replacing and transporting new and old components in assembly and disassembly. A transporting support plate is fixed on a bearing support plate, a planar sliding plate is arranged on one side of the bearing support plate, a V-shaped sliding plate is arranged on the other side of the bearing support plate, and a hollow groove is arranged between the planar sliding plate and the V-shaped sliding plate on the bearing support plate; a trolley towing hook is arranged on the ends of the transporting support plate and the bearing support plate, a hook is arranged at the front of the trolley towing hook, the trolley towing hook is concave, top ends of connecting plates at both sides are connected through a pull plate, and the connecting plates are provided with rib plates. The tool, provided by the utility model, is simple in manufacturing structure and can be produced according to actual field conditions. When components of a bending and shifting roll device are maintained and replaced, the working efficiency is improved, the working time is shortened, and the labor intensity of workers is reduced. The working efficiency is improved, the tool can be used for a rolling mill provided with the components of a bending and shifting roll device on a steel rolling production line, and meanwhile, the tool can be used in a rolling mill with large parts to be disassembled and transported.

Description

The inner large assemblies of milling train is changed the instrument that transports

Technical field

The utility model belongs to mechanical field.

Background technology

Milling train unit on the steel rolling production-line; Unit inside is equipped with curved roll shifting device assembly; Equipment is slide plate on the curved roll shifting device assembly and subelement meeting appearance damage in the production use; To need to bend the roll shifting device assembly in case of necessity and dismantle, have bad luck and carry out slide plate to the milling train outside and change and handle other equipment deficiencies.Inner at milling train because of curved roll shifting device assembly, it is outside to need that when dismounting old assembly is had bad luck milling train, New Parent is had bad luck to milling train inner, or after the defective of old assembly handled; Return and install to milling train inside, narrow and small because of the milling train inner space, and assembly weight is heavier, leans on manual work not carry; Can only rely on chain block, progressively have bad luck back and forth, have bad luck in the process very cumbersome; And the time is long, and labor strength increases, and dangerous in the transportation.

Summary of the invention

The purpose of the utility model provide a kind of can be on milling train walking freely, accomplish the inner large assemblies of milling train of new and old unit replacement translocation in the dismounting and change the instrument that transports.

Transport support board is fixed on and carries on the gripper shoe, carries gripper shoe one side the plane slide plate is installed, and opposite side is equipped with the V-type slide plate, between plane slide plate on the carrying gripper shoe and V-type slide plate, free groove is arranged; In Transport support board and the end of carrying gripper shoe the dolly towing hook is installed, dolly towing hook front end has hook, and the dolly towing hook is a spill, and the connecting plate top of both sides connects through arm-tie, and gusset is installed on connecting plate.

The utility model manufacturing structure is simple, all can manufacture according to on-site actual situations.When carrying out the curved roll shifting device assembly of maintain and replace, improve operating efficiency, shorten the activity duration, alleviate labor strength.Increase work efficiency, the milling train that on steel rolling production-line, has curved roll shifting device assembly all can use, and has large parts simultaneously in milling train inside and carries out all can using of dismounting transportation.

The specific embodiment

Transport support board 1 is fixed on and carries on the gripper shoe 2; Transport support board 1 with carry gripper shoe 2 also can one-shot forming, carry gripper shoe 2 one sides plane slide plate 5 be installed, opposite side is equipped with V-type slide plate 6; The design of plane slide plate 5 and V-type slide plate 6 be for milling train on corresponding design of slide rail on the roll change platform; So, slide rail be the plane correspondence be plane slide plate 5, slide rail is the corresponding V property slide plate 6 of V-type.Between the plane slide plate 5 and the V-type slide plate 6 that carry on the gripper shoe 2, free groove 7 is arranged, empty groove 7 is in order to hide following backing roll on the milling train; In Transport support board 1 and the end of carrying gripper shoe 2 dolly towing hook 3 is installed, dolly towing hook 3 front ends have hook 4, and dolly towing hook 3 is a spill, and connecting plate 9 tops of both sides connect through arm-tie 10, and gusset 8 is installed on connecting plate 9.

The utility model is manufactured one exactly and is transported dolly, utilizes mill roll track and roll change push-and-pull cylinder, will bend the roll shifting device assembly at needs and dismantle when having bad luck; To transport dolly and hang onto mill roll track place, and utilize roll change push-and-pull cylinder to be pushed into milling train inside, will bend after roll shifting device assembly dismounting finishes in milling train inside; Put to transporting on the dolly; Utilize the push-and-pull cylinder that dolly is retracted, will bend the roll shifting device assembly and transport, hang away to the milling train outside; The new curved roll shifting device assembly spare part of then needs being changed is placed on the transport trolley, utilizes roll change push-and-pull cylinder that dolly is pushed milling train inside, will bend the roll shifting device assembly simultaneously and be transported to milling train inside, will bend the roll shifting device assembly and install.
