Description

Technical Field

[0001] The invention relates to the technical field of aluminum processing, and in particular to a feeding system for an aluminum alloy ingot sawing line. Background Art

[0002] The aluminum alloy melting and casting workshop mainly produces ingots for rolling aluminum plate and strip products, also called aluminum plate ingots, which are one of the main products achieved by alloying with electrolytic aluminum liquid. The process includes smelting, alloying, insulation, purification, casting and sawing. After that, the ingots are sent to the rolling workshop and then, after removing the surface oxide scale and heating, they can be used in the rolling mill to roll out aluminum plates and aluminum coils.

[0003] At present, my country's melting and casting workshops have basically achieved automation from smelting to casting. After casting, the ingots are manually lifted out of the casting machine (also known as the casting well) using a crane and special lifting equipment and laid on the ground (see Figure 1 , Figure 2 ), and then replace another set of special lifting equipment (see Figure 3 ) Grab the center of the horizontally placed ingot, lift it and place it on the cross-span transfer vehicle, which will then transport it across the span to the adjacent workshop for sawing and storage. In the sawing and storage workshop, the ingot is manually placed at the loading and buffering station of the sawing line using a workshop crane and special lifting equipment (see Figure 4 ), there are also casting machines and sawing lines in the same workshop, which can be directly placed on the loading position of the sawing line. The feeding car on the sawing line feeds the ingots to the sawing line according to the sawing rhythm. After the ingots are sawed, they are sent to the rolling workshop or sold to the rolling factory. It can be seen that after the ingot is cast, it needs to be lifted out of the casting well and hoisted to the sawing line for two to three times using workshop cranes and special hoists for manual lifting and one-time cross-transfer, which requires personnel and equipment. In particular, there are safety hazards in the first process of lifting the ingot out of the casting well and laying it on the ground (see Figure 4). The length of the ingot is generally from 7 meters to 9 meters, and the longest can reach 12 meters at present. When the ingot is out of the well, the hoist is hung at the end of the ingot. After it is lifted vertically out of the casting well, the lower end of the ingot falls to the ground, and the crane moves while releasing the hook wire rope to drag the ingot down. The weight of an ingot ranges from 15 to 40 tons. This process requires high operating skills of the crane operator, and the ground personnel should stay away from the area when laying it down. This is also one of the safety hazards in the current melting and casting workshop.

[0004] Therefore, a feeding system for an aluminum alloy ingot sawing line with high safety and the ability to automatically transport the aluminum ingots to the sawing line after casting has become a goal pursued by those skilled in the art. Summary of the invention

In particular, the ingot turning and laying down mechanism is installed in the turning pit, and the middle part of the frame of the ingot turning and laying down mechanism is provided with rotation support by two supporting mechanisms installed in the turning pit platform foundation. When the frame of the ingot turning and laying down mechanism is turned to an upright state, the lower half thereof enters into the turning pit. When the ingot is vertically lifted out of the casting pit, it does not need to be lifted out to the ground completely, and it can be directly transferred into the turning pit and placed on the frame of the ingot turning and laying down mechanism. At this time, the frame of the ingot turning and laying down mechanism has been driven to rotate to a roughly vertical state by the hydraulic lifting mechanism. Therefore, the ingot can be directly lifted and placed into the ingot slot at the end of the frame, and the ingot is leaning against the frame, and then the rotating frame is driven to a horizontal state by the hydraulic lifting mechanism. When the ingot is rotated to a horizontal state with the ingot rack, the power roller mechanism on the ingot turning and laying down mechanism can be docked with the ground roller mechanism, and the electric transfer vehicle on the transfer vehicle system travels to the other end of the ground roller mechanism and docks with it, so that the ingot can be transported from the power roller mechanism of the ingot turning and laying down mechanism and through the ground roller mechanism to the middle of the vehicle-mounted roller mechanism of the transfer vehicle system, and then the rotation is stopped, and the electric transfer vehicle is started to the end of the feeding roller of the sawing line, and the transfer vehicle roller driving mechanism and the feeding roller of the sawing line are started again, that is, the ingot can be directly transported to the feeding roller of the sawing line, thereby completing the automatic feeding of the ingot sawing. Compared with the prior art, the present invention saves ingot casting time and energy. After the ingot is lifted out of the casting pit, it is laid down little by little by manually operating a crane, which saves the special lifting tools and operations for lifting the ingot horizontally to a transfer vehicle or to a sawing line after it is laid down. Since the weight of the ingot is generally between 15 and 40 tons, the ingot flipping and laying mechanism of the present invention can achieve safe laying down of the ingot. A powered roller mechanism is provided on the ingot flipping and laying mechanism, a ground roller mechanism is provided on the ground, and a vehicle-mounted roller mechanism is provided on the electric transfer vehicle, thereby achieving horizontal roller conveying of the ingot without the need for horizontal lifting with special lifting tools. This makes the entire transportation process automatic, safe and reliable, and avoids potential safety hazards during the lifting process.

[0027] Furthermore, the present invention arranges two ingot guiding bars on both sides of the frame base structure near the ingot slot, and vertical rollers are arranged on both sides of the frame base structure, which can make the ingot easier to operate when it is hung on the frame and the ingot will not deviate when walking on the frame roller.

[0028] Furthermore, the rollers, the ground rollers and the transfer vehicle rollers are made into symmetrical cones with thick ends and thin middle, which can make the ingot move along the center on the rollers without deviating from the center.

[0029] Furthermore, the present invention provides two locking mechanisms on the support mechanism, which are used to lock the frame in a horizontal position or an upright position respectively when maintenance or replacement of the hydraulic cylinder is required, so that the equipment can be inspected and maintained. When in a locked state, the lock pin position sensor will give a signal to the control system, and at this time, it is in a locked state, and all operating mechanisms will not start.

[0030] Furthermore, the present invention provides two stop arms on both sides of the connecting base as a limiting mechanism, which is used to limit the frame from flipping to the upright position to prevent it from over-flipping. The preferred solution of the limiting mechanism is to directly set it at the bottom of the connecting base of the hydraulic lifting mechanism, and to extend the two stop arms in the horizontal direction.

[0031] Furthermore, the buffer base at the bottom of the ingot slot of the present invention can reduce the impact force when the ingot falls into the ingot slot.

[0032] Furthermore, the present invention provides a flip angle detection mechanism at the end of the flip shaft, so that the flip angle can be detected and transmitted to the control system for automatically controlling the flip to a specified upright position and a horizontal position.

[0033] Furthermore, and this is also special, since the ingot turning and laying device is directly installed on the turning pit, the turning pit is adjacent to the casting well and communicates with the casting well, the ingot can be transferred into the turning pit and placed in the ingot turning and laying device after being hoisted out of the casting well by about half, and for the newly built melting and casting workshop, the height of the workshop can be reduced by about half of the height of the ingot, saving the cost of the workshop construction. At the same time, the investment in the crane and hoisting equipment for horizontal lifting is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the preferred embodiments cannot be used to limit the protection scope of the present invention.

[0052] See also Figure 5, the figure shows a preferred embodiment of the present invention, a feeding system of an aluminum alloy ingot sawing line, characterized in that it includes: an ingot turning and laying mechanism 1, a ground roller mechanism 2 and a transfer vehicle system 3; the ingot turning and laying mechanism 1 is used to turn the ingot to a horizontal state, the ground roller mechanism 2 is used to horizontally transport the ingot on the ingot turning and laying mechanism 1 to the transfer vehicle system 3, and the transfer vehicle system 3 is used to transport the ingot to the feeding roller 101 of the sawing line 100; in this embodiment, as a preferred embodiment, a feeding system is set between two casting wells 200 and a sawing line 100, wherein the ingot There are two flipping and laying mechanisms 1, which are respectively arranged adjacent to two casting shafts 200. The ingot flipping and laying mechanism 1 is arranged on a flipping pit 4 located below the ground. The flipping pit 4 and the casting shaft 200 are arranged adjacent to each other and are connected as a whole. The flipping pit 4 where the ingot flipping and laying mechanism 1 is arranged is arranged adjacent to the casting shaft 200, and the two are connected. When the ingot flipping and laying mechanism 1 is turned to an upright state, the ingot 300 can be pushed out from the casting shaft 200 through the casting lifting cylinder 201. After the crane lifts out the ingot with a special lifting device, it does not need to be lifted out of the ground completely, and it can directly enter the flipping pit 4 and be lifted into the ingot flipping and laying mechanism 1. A powered roller mechanism 12 for horizontally conveying ingots is provided on the ingot turning and laying mechanism 1. Two ground roller mechanisms 2 are respectively arranged at the tail ends of the powered roller mechanisms 12 of the two ingot turning and laying mechanisms 1. When the ingot turning and laying mechanism 1 is rotated to a horizontal position, the powered roller mechanism 12 can be docked with the ground roller mechanism 2. There is one transfer vehicle system 3, which is arranged between the ends of the two ground roller mechanisms 2 and the material roller 101 of the sawing line 100. The transfer vehicle system 3 is respectively docked with the ends of the ground roller mechanism 2 and the ends of the material roller 101 of the sawing line 100, and can receive the ingots conveyed by the ground roller mechanism 2 and transfer them to the material roller 101 of the sawing line 100.

[0053] It is understandable that if the two ground roller mechanisms 2 are not arranged in a straight line, the transfer vehicle system 3 can be extended so that it can be docked with the tail ends of the two ground roller mechanisms 2, or if the two ground roller mechanisms 2 cannot share a transfer vehicle system 3, a transfer vehicle system 3 can be added. Obviously, the present invention can also be one casting well or multiple casting wells corresponding to one sawing line. If there is one casting well and one sawing line, then it is necessary to configure an ingot flipping and laying mechanism 1, a ground roller mechanism 2 and a transfer vehicle system 3. If multiple casting wells correspond to one sawing line, then the shared method in this embodiment can be adopted to reduce the configuration. However, one ingot flipping and laying mechanism 1, one ground roller mechanism 2 and one transfer vehicle system 3 are the minimum configuration.

Obviously, it can also be formed by connecting one side of a member with a U-shaped cross section to one end of the frame basic structure 111, or by connecting a straight L-shaped member 119 at one end of the frame basic structure 111. A U-shaped ingot slot 112 is formed, and the U-shaped ingot slot 112 formed at the end is used to place the ingot.

First, the ingot flipping and laying mechanism 1 is lifted and rotated to the upright position by the hydraulic lifting mechanism 14, such as Fig. 9As shown, the position is preferably close to a vertical position, preferably about 80 degrees to the ground, so that the electric transfer vehicle 32 of the transfer vehicle system 3 is in a position to dock with the ground roller mechanism 2, and then, the ingot is vertically lifted out of the casting well 200 by a crane and a special lifting device, and moved to the bottom ingot slot 112 of the ingot turning and laying mechanism 1 on the turning pit 4, and the ingot is tilted against the roller 125 of the frame basic structure 111. At this time, the frame basic structure 111 of the ingot turning and laying mechanism 1 is in an 80-degree state, and then, the hydraulic lifting mechanism 14 falls back to rotate the frame 11 to a horizontal position. At this time, the roller 125 of the ingot turning and laying mechanism 1, the ground roller 22 of the ground roller mechanism 2 and the transfer vehicle roller 332 of the vehicle-mounted roller mechanism 33 are in the same plane and are arranged along a straight line, and the roller drive mechanism is started at the same time and at the same speed. The roller 125, the ground roller 22 and the transfer vehicle roller 332 rotate at the same speed at the same time, and the ingot is transported from the ingot flipping and laying mechanism 1 to the vehicle-mounted roller mechanism 33 of the transfer vehicle system 3 via the ground roller mechanism 2. When the ingot moves to the central position of the vehicle-mounted roller mechanism 33, the roller drive mechanism, the ground roller drive mechanism 23 and the transfer vehicle roller drive mechanism 333 are stopped, and then the electric transfer vehicle 32 is started. The electric transfer vehicle 32 travels along the transfer vehicle track 31 from the docking position with the ground roller mechanism 2 to the docking position with the feeding roller 101 of the sawing line 100, and the transfer vehicle roller drive mechanism 333 and the feeding roller 101 of the sawing line 100 are started synchronously and at the same speed to transport the ingot to the sawing line, completing the automatic feeding process of the sawing line. Then, the ingot flipping and laying mechanism 1 is lifted and rotated to the upright position by the hydraulic lifting mechanism 14, and the electric transfer vehicle 32 of the transfer vehicle system 3 travels back to the position docking with the ground roller mechanism 2, waiting for the transportation of the next ingot.

[0064] It can be seen that the present invention can realize that the ingot is safely transferred from the vertical state of lifting to the horizontal state by adopting the ingot turning and laying mechanism 1. In particular, the ingot turning and laying mechanism 1 is arranged in the turning pit 4. When it is turned to the horizontal state, it is just horizontally docked with the ground roller mechanism 2. A transfer vehicle system 3 can be used to realize cross-transfer, that is, to realize the transfer perpendicular to the transportation direction of the ground roller mechanism 2. When the transfer vehicle system 3 travels to the end of the ground roller mechanism 2, it can receive the ingot, and then travel to the end of the feeding roller 101 of the sawing line 100 to transport the ingot to the sawing line 100. Therefore, the present invention saves the special sling used for horizontally lifting the ingot ( Figure 3 The biggest advantage is that its safety is greatly improved, avoiding potential safety hazards during horizontal lifting and laying down, and can realize automatic control of ingot feeding. Figure 5 , 6In this example, the turning pit 4 is arranged adjacent to the casting well 200 (casting machine), and the turning pit 4 extends all the way to be connected with the casting well 200; the advantage of this is that the ingot can be directly placed in the ingot turning and laying mechanism 1 for turning after being lifted out of the casting well 200, without the need to be lifted out of the ground, thereby greatly reducing the height of the ingot lifted out of the casting well, reducing the difficulty of the lifting workers, improving safety, and also reducing the installation height of the workshop crane.

The ingot guide bars 114 and the vertical rollers 116 play a guiding role when the ingot is suspended on the frame basic structure 111 to prevent the ingot from deviating. On the other hand, the vertical rollers 116 play a guiding role when the ingot is horizontally transported to the ground roller mechanism 2 to prevent it from deviating.

After adjusting to the appropriate position, tighten the fixing bolt to fix the tensioning wheel seat 1241.

[0070] See also Figure 8 ,11, 12, further, as a preferred embodiment, the two ends of the roller 125 are fixed to the roller mounting seats 120 on both sides of the frame base structure 111 through roller bearing seats 122.

The manual locking mechanism 16 also includes a pin hole 118 on the side of the frame 11 that cooperates with the lock pin 162 of the manual locking mechanism 16. When the handle 163 is moved to the unlocking position lock slot 1613, the lock pin 162 is in the retracted state. When it is necessary to lock the ingot flipping and laying mechanism 1, the handle 163 is pulled upward to make the handle stand up to the long slot 1611 position, and the handle 163 is pushed forward to drive the lock pin 162 to extend and insert into the pin hole 118 on the side of the frame 11. Then, the handle 163 is pulled downward to make it enter the locking position lock slot 1612, so that the lock pin 162 can be kept in a locked state. The manual locking mechanism 16 is for maintenance safety. When the equipment needs maintenance, the two manual locking mechanisms 16 are used: one is locked when the frame 11 is in an 80-degree upright state, and the other is locked when the frame 11 is in a horizontal state. When the frame 11 is repaired in two positions, the lock pin 162 is manually inserted into the pin hole 118 on the frame 11 through the handle 163. A lock pin position sensor 164 that monitors the position of the lock pin 162 senses that the manual locking mechanism 16 is opened and automatically flips to start. Ensure that the ingot flipping and laying mechanism 1 does not move during maintenance. A pedal can be set on the frame 11 to facilitate maintenance personnel to work in a horizontal position.

[0074] See also Fig.12 Further, as a preferred embodiment, the roller 125, the ground roller 22 and the transfer vehicle roller 332 have the same structure, all of which are thin in the middle and thick at both ends and are symmetrically conical, that is, a cylindrical part 1251 is provided in the middle, and conical parts 1252 are provided on both sides of the cylindrical part 1251. The conical parts 1252 on both sides are symmetrically arranged, and the diameter in the middle is small and the diameters at both ends are large.

[0075] The automatic control system includes: a PLC controller, a flip angle detection mechanism 15 installed at the end of the flip shaft, which is used to monitor the flip angle of the ingot flipping and laying mechanism 1. The automatic control system outputs a signal to the control system through the flip angle detection mechanism 15 installed at the end of the flip shaft 115 on the frame 11 to control the lifting and lowering of the hydraulic cylinder of the hydraulic lifting mechanism 14. And the photoelectric switches installed on the frame 11, the roller support 21, and the transfer vehicle roller 331 are used to monitor the position of the ingot, send signals to the PLC controller, and control the start and stop of each section of the roller.
