[0002] In recent years, with the prosperity of the world economy, steel consumption and steel production have increased year by year, and competition has become increasingly fierce. The most direct way to create benefits is to improve production efficiency and reduce production costs. Therefore, improving the degree of automation of production lines and reducing overall production costs are top priorities. At the same time, the degree of automation of production lines is also an important criterion for measuring the degree of modernization of steel enterprises.

[0003] As one of the important links in the metallurgical production process, hot rolling has the characteristics of high frequency, strong coupling nonlinearity, and temperature, phase change, and stress coexist. In recent years, the development of industrial automation technology has made great progress in hot rolling in terms of main line automation, variety specifications, product quality, and information integration. However, there are still the following problems that need to be solved: the heating capacity of ingredients, the rhythm of rolling lines, multi-area scheduling, and smooth production. These problems affect the release of production capacity, and the demand for efficient production is urgent. Among them, insufficient control accuracy, low level of equipment intelligence, lack of key detection, and imperfect monitoring are the main reasons. Introducing robot feeding and unloading equipment in metallurgical production has become one of the important ways to solve the above problems.

[0004] However, the existing robot feeding and unloading equipment simply adjusts and feeds the blanks, but is unable to adjust, control, and recycle the temperature of the blanks, resulting in a relatively simple functionality and very limited auxiliary function. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the existing robot feeding and unloading equipment simply adjusts and feeds the blanks, but cannot adjust, control and recycle the temperature of the blanks, resulting in its relatively simple functionality and very limited auxiliary function.

[0012] The split heat recovery cover comprises an electrically controlled telescopic cover slidably mounted on the outside of a flip adjustment plate and a circulating flow guide module mounted on the side wall of the electrically controlled telescopic cover.

[0013] A top heat storage box is fixedly mounted above the transverse guide rail through lateral suspension arms on both sides, and the top heat storage box is connected to the heat exchange pipeline through a lateral flow guide pipe passing through a fixed flow guide assembly frame.

[0014] The electrically controlled telescopic cover comprises a lateral adjustment frame of an inverted L-shaped structure slidably mounted on the upper end of a flip adjustment plate and an upper electrically controlled screw rod for controlling the translation of the lateral adjustment frame.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Figure 1 , Figure 2 , Figure 3 and Figure 4 The shown embodiment is a lifting type loader and feeder for material distribution in a metallurgical hot rolling workshop with a heat recovery function, comprising a main frame 1, a top translation guide rail 2 is fixedly installed on the top surface of the main frame 1, an electric-controlled lifting guide rail 3 is movably installed inside the main frame 1 through the top translation guide rail 2, a bottom lifting part 4 is movably installed at the bottom of the electric-controlled lifting guide rail 3, and flip-type lateral heat insulation panels 5 are movably installed on both sides of the bottom lifting part 4, and a split heat recovery cover 6 is installed on the flip-type lateral heat insulation panel 5.

[0032] Working principle: The bottom hoisting part 4 clamps and fixes the blank from both sides, and then the blank is fed into and out of the hot rolling process by electrically controlled translation along the top translation guide rail 2.

[0033] In order to cooperate with the lifting and translation, the electrically controlled lifting guide rail 3 includes a top lifting frame 31 movably installed on the top translation guide rail 2, electrically controlled wheels 32 installed on both sides of the top lifting frame 31, a lateral lifting arm 33 fixed on the side wall of the top lifting frame 31 and a transverse guide rail 34 fixed at the bottom end of the lateral lifting arm 33.

[0034] The electric-controlled wheel 32 rotates to drive the lateral boom 33 to perform translation adjustment along the top translation guide rail 2 .

[0035] In order to cooperate with the support and electric control translation adjustment, the top hoisting frame 31 is inserted into the top translation guide rail 2 through the electric control wheels 32 on both sides and is movably assembled with the top translation guide rail 2.

[0036] In order to cooperate with the top adjustment, a strip guide groove is provided at the upper end of the transverse guide rail 34, and an electrically controlled adjustment screw rod 35 is movably installed inside the strip guide groove.

[0037] In order to cooperate with translation adjustment and bottom lifting, the bottom lifting part 4 includes an internally threaded translation block 41 threadedly mounted on the electrically controlled adjustment screw 35, a lateral translation frame 42 fixed on the side wall of the internally threaded translation block 41, and a bottom scissor-type lifting claw 43 movably mounted at the lower end of the lateral translation frame 42.

[0038] By rotating the electrically controlled adjusting screw 35, the internal threaded translation block 41 is controlled to translate and adjust inside the strip guide groove, and then the lateral translation frame 42 is driven to perform controlled translation, so that the bottom scissor-type lifting claws 43 can be adjusted to the middle position of the blank. The bottom scissor-type lifting claws 43 are prior art, and the blank is fed after being clamped at both ends by a scissor-type bracket and the clamping claws at the bottom thereof, and the control power supply is used to control the internal control struts of the scissor-type bracket.

[0039] In order to control the temperature of the blank after lateral flipping, the flip-type lateral insulation plate 5 includes a fixed guide assembly frame 51 fixedly installed on both sides of the bottom scissor-type lifting claws 43, a flip adjustment plate 52 movably installed on the outside of the fixed guide assembly frame 51, a heat exchange pipe 53 fixed on the inner top surface of the flip adjustment plate 52 and a bottom adjustment support rod 54 for controlling the flip adjustment plate 52.

[0040] The upper end of the bottom adjustment strut 54 is movably assembled with the side wall of the fixed guide assembly frame 51, and the lower protruding end is movably assembled with the flip adjustment plate 52. The bottom adjustment strut 54 controls the flip adjustment plate 52 to flip and adjust by telescoping. When idle, the bottom adjustment strut 54 controls the flip adjustment plate 52 to flip upward and be stored, and fit on both sides of the bottom scissor-type lifting claws 43. When heat exchange is required during lifting, the flip adjustment plate 52 is controlled to flip downward and be horizontally set at a close distance to the upper surface of the blank.

[0041] In order to cooperate with the electric control extension, the split heat recovery cover 6 includes an electric control telescopic cover 61 slidably mounted on the outside of the flip adjustment plate 52 and a circulating guide module 62 mounted on the side wall of the electric control telescopic cover 61 .

[0042] An embedded infrared positioning module is fixed on the side wall of the electrically controlled telescopic cover 61 , and the extended position of the electrically controlled telescopic cover 61 is adjusted by the embedded infrared positioning module, thereby adapting the blank structure.

[0043] In order to cooperate with the top heat storage, a top heat storage box 7 is fixedly installed above the transverse guide rail 34 through the lateral suspension arms 33 on both sides. The top heat storage box 7 is connected to the heat exchange pipe 53 through the lateral guide pipe 8 through the fixed guide assembly frame 51.

[0044] The top heat storage tank 7 adopts a double-layer liner design to enhance internal thermal insulation. Temperature sensor controller modules are installed inside the top heat storage tank 7 and the heat exchange pipe 53 to control the opening and closing of the circulating liquid pump on the bottom surface of the top heat storage tank 7. When the temperature inside the top heat storage tank 7 is relatively high and the temperature inside the heat exchange pipe 53 is relatively low, and heating is required, the circulating liquid pump is started to introduce the heat exchange liquid inside the top heat storage tank 7 into the heat exchange pipe 53; when the temperature inside the heat exchange pipe 53 is relatively high and the temperature inside the top heat storage tank 7 is relatively low, and cooling and heat recovery are required, the circulating liquid pump is started to introduce the heat exchange liquid inside the heat exchange pipe 53 into the top heat storage tank 7.

[0045] In order to cooperate with the electric control translation adjustment, the electric control telescopic cover 61 includes a lateral adjustment frame 611 of an inverted L-shaped structure slidably mounted on the upper end of the flip adjustment plate 52 and an upper electric control screw rod 612 for controlling the translation of the lateral adjustment frame 611.

[0046] An upper assembly frame for installing an upper electric control screw 612 is provided at the upper end of the flip adjustment plate 52, and an internal thread translation block matching with the upper electric control screw 612 is provided at the upper end of the lateral adjustment frame 611. The internal thread translation block and the lateral adjustment frame 611 are driven to perform translation adjustment by the rotation of the upper electric control screw 612.

[0047] In order to coordinate and control the staggered flow of internal air, the circulating air guide module 62 includes a lateral air guide cover 621 fixedly mounted on the inner side of the lateral adjustment frame 611, an electrically controlled blade 622 mounted inside the lateral air guide cover 621, and a lateral air guide nozzle 623 fixedly mounted on the outer curved surface of the lateral air guide cover 621.

[0048] The electric-controlled blades 622 draw in air from the bottom of the flip adjustment plate 52 through the rotation speed, and then blow the air laterally back to the inside of the flip adjustment plate 52 from the other side through the side guide nozzles 623 on the outside of the side guide cover 621. The circulating guide module 62 adopts a staggered layout to form a serpentine flow direction at the bottom of the flip adjustment plate 52, which is the same as the flow direction of the heat exchange pipe 53.

[0049] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
