Description

Technical Field

[0001] The utility model relates to the technical field of steel billet production, in particular to a heat-insulating steel pushing device for a hot delivery roller. Background Art

[0002] In the heating process of steel rolling production, hot charging and hot delivery are generally adopted. The high-temperature continuous casting billet is directly transferred to the heating furnace through the conveyor roller. Through the hot delivery and hot charging of the continuous casting billet, the continuous casting billet can be heated to the target temperature at a higher temperature. In the heating process, it can effectively reduce energy consumption, improve heating efficiency, and reduce heating time. When using roller conveyor, most of them use insulation covers. When the downstream heating furnace cannot receive the continuous casting billet in time, the overhead crane will be used to lift the offline billet away, so some hot delivery rollers will cancel the insulation covers. If the output of the downstream steel rolling mill is increased, it will cost a lot of money, but if the insulation cover is not added to the hot delivery roller, it will cause heat loss and increase the use of gas in the heating furnace.

[0003] For example, the utility model with the announcement number CN211726958U discloses an indirect hot delivery and hot charging device for continuous casting billets, the device is composed of a double-layer roller and a heat preservation cover, the double-layer roller includes a hot delivery roller and an indirect hot delivery roller; wherein the heat preservation cover matches the structural dimensions of the double-layer roller, completely covers the heat preservation roller and the corresponding hot delivery roller part located thereunder, and the indirect hot delivery roller is placed on the hot delivery roller. Although the utility model realizes 100% hot delivery and hot charging production, it still cannot solve the problem that there is nowhere to place the billets when the upstream hot delivery roller is overproduced, and the crane is inconvenient to work when the heat preservation cover is set on the hot delivery roller.

[0004] In view of this, the inventor conducted in-depth research on this demand, and thus the present case was produced. Utility Model Content

[0005] In order to overcome the problems in the prior art that there is nowhere to place the steel billets when the upstream hot delivery roller is over-produced, and that the crane is inconvenient to work when a heat preservation cover is provided on the hot delivery roller, the utility model provides a heat preservation steel pushing device for the hot delivery roller, comprising a mechanical arm and a steel billet platform respectively arranged on both sides of the hot delivery roller, and a heat preservation cover is provided above the hot delivery roller.

[0007] When the hot delivery roller conveys the steel billet to a fixed position, the mechanical arm drives the push rod to push the steel billet from the hot delivery roller to the steel billet platform through the motor rotating gear, and then the staff directs the overhead crane to lift the steel billet on the steel billet platform.

[0008] Preferably, a push plate is provided at one end of the push rod close to the hot delivery roller to facilitate pushing the steel billet.

[0009] Preferably, the robotic arm further comprises an auxiliary rod for guiding the push rod, the auxiliary rod being arranged on both sides of the push rod, and being slidably mounted on the base and being slidable along the length direction of the push rod, and the push rod being fixedly connected to the auxiliary rod.

The gear is linked with the rack, and the auxiliary rod is fixedly connected with the push rod. When the motor is started, the gear rotates on the rack, driving the auxiliary rod forward or backward, and the push rod moves forward or backward at the same time.

[0011] Preferably, the side of the heat preservation cover close to the robot arm is provided with an opening, and the side of the heat preservation cover close to the billet platform is provided with a rectangular opening whose length along the direction of the hot delivery roller is greater than the length of the billet. While the hot delivery roller ensures the sealing of the heat preservation cover, it is convenient for the robot arm to enter the heat preservation cover to operate and push the billet to the billet platform.

[0012] Preferably, the billet platform includes a support frame, a placement table and a displacement bar. The placement table is arranged inside the support frame. The placement table is built of refractory materials. There are several displacement bars on the placement table that are evenly spaced and parallel to each other. One end of the displacement bar faces the hot delivery roller, and the upper surface is flush with the hot delivery roller.

[0013] Preferably, the support frame is welded by steel plates, and train wheels are arranged at the four corners, and the train wheels are matched with the steel rails on the ground. The support frame is welded into an outer frame steel plate, and refractory bricks are placed inside to form the placement platform, which can withstand the heat of the upstream steel billet. A high-power motor is arranged at the bottom of the support frame, which is connected to the train wheel soft wire, and can be matched with the steel rails on the ground to make the steel billet platform set as a movable platform.

[0014] Preferably, the displacement bar is a steel material with a smooth surface. The displacement bar plays a traction role during the pushing process of the steel billet, so as to prevent the refractory material in the middle of the placement table from being damaged due to the pushing of the steel billet.

[0015] Preferably, a liftable cover is provided on one side of the heat preservation cover close to the billet platform. When the robot arm pushes the billet in the heat preservation cover, the cover on one side of the heat preservation cover close to the billet platform can be lifted to push the billet directly to the billet platform.

[0016] The beneficial effects produced by adopting the technical solution of the utility model are as follows:

[0017] (1) By setting up a heat preservation cover, it is ensured that the heat of the steel billets transported to the downstream heating furnace is not lost, and the effect of hot loading and hot delivery is achieved.

[0018] (2) A movable billet platform is provided to facilitate the operation of the overhead crane. A liftable heat preservation cover is provided to facilitate the operation of the robot arm, so that the surplus billet can be pushed to the billet platform more easily.
