Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present specification without any inventive step should fall within the scope of protection of the present specification.

Referring to fig. 1 to 3, the embodiment of the present application discloses a device for rapidly replacing a movement of a tandem mill, comprising:

the continuous rolling mill comprises a plurality of rolling mills 10 which are arranged side by side, and each rolling mill 10 is provided with a replaceable machine core;

a deck replacing device, provided on the rolling mill 10, for pulling the deck to the rolling mill 10 and separating the deck from the rolling mill 10;

the first track 20 is arranged on the same side of the movement;

a first loading wagon 40, which is arranged on the first rail 20 and can move transversely on the first rail 20, and is used for carrying a first machine core;

a second loading wagon 50, longitudinally movable with respect to the first rail 20, is provided for carrying a second movement.

In one example, the movement replacing device comprises a pusher 101 mounted on the rolling mill 10, wherein the pusher 101 comprises pushing arms detachably connected to two sides of the movement, the pushing arms are connected with a driver, and the pushing arms are driven by the driver to clamp the movement to move relative to the rolling mill 10. Furthermore, the driver can be an oil cylinder, a hydraulic cylinder or a motor to enable the pushing arm to reciprocate.

The so-called tandem rolling mill 10 is composed of a plurality of rolling mills 10 arranged in parallel in a straight line in a workshop, which not only effectively utilizes the workshop space, but also facilitates the management of the plurality of tandem rolling mills 10. for example, in the present application, the first loading truck group 40 includes a plurality of loading trucks arranged side by side, and one loading truck corresponds to one rolling mill 10, so that the core replacement processing can be simultaneously performed on the plurality of rolling mills 10 arranged side by side, and the production efficiency is improved.

Based on the above structure, the second loading truck group 50 includes the truck bodies corresponding to the number of the rolling mills 10 and arranged side by side, the adjacent truck bodies are fixedly connected by bolts, and each truck body is installed with a laser sensor and a controller, the laser sensor is used for sending a measurement of the moving distance of the truck body to the controller, and the controller controls the truck body to move according to the moving distance of the truck body. Since the second loader group 50 needs to move to a fixed position when loading the movement, the position deviation does not exceed 1mm, otherwise the movement cannot be accurately guided into the installation position of the movement on the rolling mill 10, the movement distance of the vehicle body is detected by using a laser sensor, and the vehicle body can conveniently and correctly send the movement to a preset position. Specifically, as shown in the figure, the car body carries a new movement to move towards the rolling mill 10, the laser sensor continuously detects the distance between the car body and the rolling mill 10, the distance measurement result is fed back to the controller, and the controller controls the moving wheels on the car body to move forwards or stop or retreat according to the distance measurement result.

All install 2 on every automobile body and remove the wheelset, second loading car group 50 has 6 to remove the wheelset like this, and every removes the wheelset and includes a pair of removal wheel, and auxiliary wheel 501 is installed to the both sides of every removal wheel, and auxiliary wheel 501 increases and removes the area, can ensure the straightness accuracy that traveles of automobile body to a certain extent, prevents that the automobile body from walking askewly.

When the second loading truck group 50 moves relative to the rolling mill 10, the second loading truck group needs to pass through the first rail 20, so the gap between the moving wheel groups on the same side of the truck body is larger than the width of the first rail 20, and thus the two groups of wheels are in a suspended state and still contact with the rails, so that the truck body does not generate vibration due to rail passing in the running process, and the truck body runs stably.

Further, a second rail 30 is included, the second rail 30 intersects the first rail 20, the second rail 30 is used for longitudinally moving the second loader block 50 towards the rolling mill 10, and the second rail 30 can improve the accuracy of the alignment of the car body loading movement with the core mounting position on the rolling mill 10.

Because the workshop environment is complicated, appears the iron fillings easily, so all load cars are not applicable in the rubber tire, and in this application, rack and gear are all selected to all load cars's removal wheel. Specifically, if the second loader group 50 further includes a driving device, the driving device includes a rack, a gear and a motor, the rack is mounted on the vehicle body, the gear is mounted on the second rail 30, the motor can be mounted beside the rail, and the motor drives the gear to rotate so that the rack drives the vehicle body to move on the rail.

By the structure, the movement needing to be replaced is removed from the rolling mill 10 through the first loading car group 40, and then a new movement is sent into the rolling mill 10 through the second loading car group 50 for installation, and the structure can be used for replacing the movements of a plurality of rolling mills 10 at the same time, so that the stop time of the rolling mill 10 is reduced, and the production efficiency is improved.

While the present application has been described by way of examples, those of ordinary skill in the art will appreciate that there are numerous variations and permutations of the present application that do not depart from the spirit of the present application and that the appended embodiments are intended to include such variations and permutations without departing from the present application.
