Description

Technical Field

[0001] The utility model relates to the technical field of multi-purpose furnace production, in particular to an electric material transfer table used on a multi-purpose furnace production line. Background Art

[0002] In the existing multi-purpose furnace production line, especially in the through-type furnace type fully automated production line, the furnace charge is loaded from the front chamber and unloaded from the back chamber. A reasonable production line layout generally has the loading and unloading on the same side, which is convenient for the operator to load and unload the incoming materials.

[0003] After the charge is loaded, it is necessary to transfer the charge to the front chamber feeding mechanism. Currently, this transfer process needs to be completed by the operator manually pushing the charge. Since the charge is heavy, it generally requires two or more operators to complete it, which is time-consuming and labor-intensive; especially in fully automatic production, the operator is not allowed to enter the production line after the charge enters the automated production, resulting in the inability to smoothly complete the transfer of the charge, which brings great difficulties to production; production needs to be suspended when the charge is manually transferred, which reduces production efficiency and poses certain safety risks. Therefore, it is necessary to provide an electric transfer platform for a multi-purpose furnace production line, which can solve the problems in the prior art that manual transfer of charge is time-consuming and labor-intensive, reduces production efficiency, and poses safety risks.

[0021] One end of the transfer platform body 1 is arranged near the front chamber charge loading port of the multi-furnace production line. When loading, the charge can be loaded onto one end of the transfer platform body 1, so that the charge is transported to the second conveying component through the first conveying component, and then the second conveying component pushes the transfer pushing rack 2 to transport the charge to the front chamber feeding mechanism of the multi-furnace production line. At the same time, the transfer pushing rack 2 pushes the charge to the front chamber feeding mechanism of the multi-furnace production line, completing the charge transportation between the front chamber charge loading port and the front chamber feeding mechanism of the multi-furnace production line, replacing the traditional manual transportation.

[0022] The first conveying assembly includes a first conveying chain 3, a first reduction motor 4 and a first transfer roller frame 5; a pair of first conveying chains 3 with annular structures are symmetrically arranged on both sides of the transfer platform body 1 along the length direction of the transfer platform body 1, and a pair of first conveying chains 3 are cyclically arranged between the two ends of the transfer platform body 1; the first reduction motor 4 is installed on the transfer platform body 1, and the output shaft of the first reduction motor 4 is coaxially fixed with the sprockets of the pair of first conveying chains 3; the first transfer roller frame 5 and the second conveying assembly are both installed on the transfer platform body 1 and located between the pair of first conveying chains 3, the starting end of the first transfer roller frame 5 is located at the front chamber furnace charge loading port, and the end of the first transfer roller frame 5 extends to the middle of the transfer platform body 1, that is, the starting end of the second conveying assembly.

[0023] Preferably, the first reduction motor 4 is composed of a reducer and a one-way transmission motor. The one-way transmission motor drives a pair of sprockets at the end of the first conveying chains 3 to rotate synchronously through the reducer, ensuring stable and uniform synchronous transmission of the pair of first conveying chains 3, and a pair of first conveying chains 3 perform one-way circular transmission.

[0024] Preferably, the first conveyor chain 3 is a multi-section unit chain that is hinged at the head and tail to form an annular transmission chain, and matching meshing sprockets are set at both ends of the annular transmission chain. The meshing transmission of the motor-driven transmission chain and the sprocket is a conventional transmission structure in the field and is not described here. A pusher head can be set on a section of the unit chain at the beginning of a pair of first conveyor chains 3. While the pair of first conveyor chains 3 are transmitted, the pusher head is driven to move from one end to the middle of the transfer platform body 1, and the charge is synchronously pushed to the beginning of the second conveying component in the middle of the transfer platform body 1 through the pusher head, thereby realizing the first stage of charge transportation.

[0025] Preferably, the first transfer roller frame 5 includes a pair of support frames with slots and a plurality of support rollers installed between the pair of support frames. Both ends of the support rollers are rotatably clamped between the slots relatively set on the pair of support frames through roller shafts and bushings, so that the support rollers can rotate synchronously during the conveying of charge, converting sliding friction into rolling friction, reducing resistance during the conveying of charge, and ensuring smooth conveying of charge.

[0026] The second conveying assembly includes a second conveying chain 6, a second reduction motor (not shown in the figure) and a second transfer roller frame 7; a pair of annular second conveying chains 6 are symmetrically arranged on both sides of the transfer platform body 1 along the length direction of the transfer platform body 1, and a pair of second conveying chains 6 are reciprocatingly arranged between the middle and the other end of the transfer platform body 1; the second reduction motor is installed on the transfer platform body 1, and the output shaft of the second reduction motor is coaxially fixed with the sprocket of the pair of second conveying chains 6; the second transfer roller frame 7 is installed on the transfer platform body 1 and is located between the pair of second conveying chains 6, the starting end of the second transfer roller frame 7 is located at the end of the first transfer roller frame 5, and the end of the second transfer roller frame 7 is located at the other end of the transfer platform body 1; the transfer pushing frame 2 is connected between the pair of second conveying chains 6.

[0027] Preferably, the second reduction motor is composed of a reducer and a bidirectional transmission motor. The bidirectional transmission motor drives a pair of sprockets at the end of the second conveying chain 6 to rotate synchronously through the reducer, ensuring stable and uniform synchronous transmission of the pair of second conveying chains 6, and the pair of second conveying chains 6 perform bidirectional reciprocating transmission.

[0028] Preferably, the second transfer roller frame 7 can adopt the same structure as the first transfer roller frame 5 and be used for the second stage conveying of the charge. The width of the second transfer roller frame 7 is smaller than the width of the first transfer roller frame 5. The structure of the second transfer roller frame 7 is not described in detail here.

[0029] The second transfer roller frame 7 is located at the end of the first transfer roller frame 5, and the pair of second conveyor chains 6 are respectively located on the inner side of the pair of first conveyor chains 3, so that the charge can be conveyed to the pair of second conveyor chains 6 and the second transfer roller frame 7 through the pair of first conveyor chains 3 and the first transfer roller frame 5, and then driven by the second reduction motor, the charge is driven to move through the transmission of the pair of second conveyor chains 6 to realize the second stage of conveying. At the same time, the support rollers of the second transfer roller frame 7 rotate to ensure the smooth conveying of the charge.

[0030] The pair of second conveying chains 6 are respectively equipped with push heads 601, and one end of the transfer pusher rack 2 is rotatably connected to the pusher heads 601 on the pair of second conveying chains 6 through a rotating shaft, so that the transfer pusher rack 2 is linked to the pair of second conveying chains 6 through the pusher heads 601; a guide boss 101 is formed on the transfer platform body 1, so that the other end of the transfer pusher rack 2 extends out of the other end of the transfer platform body 1 through the guide boss 101 and extends to the front chamber feeding mechanism.

[0031] Preferably, the transfer pusher rack 2 can adopt a U-shaped frame with an open start end. The two sides of the opening of the transfer pusher rack 2 are respectively connected to a pair of second conveying chains 6 through push heads 601. The closed end of the transfer pusher rack 2 is located behind the end of the second transfer roller rack 7, so that the transfer pusher rack 2 is embedded in the gap between the second transfer roller rack 7 and the pair of second conveying chains 6.

[0032] The push head 601 is located at the starting end of the second conveyor chain 6 and is driven synchronously with the second conveyor chain 6, so that when a pair of second conveyor chains 6 are driven to the front chamber feeding mechanism, the transfer pusher frame 2 can be driven to extend out of the other end of the transfer platform body 1 and extend to the front chamber feeding mechanism.

[0033] The second conveyor chain 6 can adopt the same structure as the first conveyor chain 3, with only a different chain length. Through the connection between the pusher head 601 and the rotating shaft between the unit chain at the beginning of the second conveyor chain 6 and the beginning of the transfer pusher 2, the second conveyor chain 6 drives the transfer pusher 2 to move synchronously while the horizontal transmission is in progress, and when the transfer pusher 2 moves to different positions, the angle between it and the unit chain of the second conveyor chain 6 is different, and the rotating shaft can meet the change of the connection angle between the transfer pusher 2 and the second conveyor chain 6.

[0034] The transfer platform body 1 is located at the end of the guide boss 101, and is used to provide guidance for the transmission movement of the transfer pusher rack 2, so that the transfer pusher rack 2 extends out of the transfer platform body 1 and extends to the front chamber feeding mechanism, thereby transporting the furnace charge to the front chamber feeding mechanism.

[0035] The guide boss 101 is a sloped surface structure with one end closer to the front chamber feeding mechanism being higher and the other end away from the front chamber feeding mechanism being lower, so that when the transfer pusher frame 2 is located on the transfer platform main body 1, the transfer pusher frame 2 is lower than the roller support surface of the second transfer roller frame 7; when the transfer pusher frame 2 extends out of the transfer platform main body 1 through the guide boss 101, the transfer pusher frame 2 is higher than the roller support surface of the second transfer roller frame 7.

[0036] Preferably, the slope surface of the guide boss 101 is an arc surface structure, and the end of the transfer pusher rack 2 is set to an arc surface, which is convenient for the transfer pusher rack 2 to slide out of the transfer platform body 1 along the guide boss 101, and the sliding process is smooth and unobstructed.

[0037] The slope surface of the guide boss 101 extends from the end of the second conveyor chain 6 to the end of the transfer platform body 1, and is used to lift the transfer pusher frame 2 when the transfer pusher frame 2 is horizontally driven, so that the transfer pusher frame 2 below the roller support surface of the second transfer roller frame 7 is lifted upward to be higher than the roller support surface of the second transfer roller frame 7, thereby transferring the furnace charge from the roller support surface of the second transfer roller frame 7 to the transfer pusher frame 2, and conveying it to the front room feeding mechanism with the transfer pusher frame 2. Through the arrangement of the pusher head 601 and the rotating shaft, the angle and position changes between the transfer pusher frame 2 and the second conveyor chain 6 during the translation and lifting process can be met.

[0038] The transfer platform body 1 is provided with two safety protection nets 8 , which cover the outer sides of the second reduction motor and the first reduction motor 4 respectively.

[0039] Preferably, the safety net 8 can shield and protect the motor, reducer, sprocket and other parts, play a role in collision prevention, and also prevent the transmission parts from causing accidental damage to the human body. The installation position, size, material, etc. of the safety net 8 can be adaptively adjusted according to actual use requirements to play an effective protective role.

[0040] A third transfer roller frame 9 is installed between the two ends of the transfer platform body 1 , and a pair of third transfer roller frames 9 are symmetrically arranged in the gap between the outer sides of a pair of first conveyor chains 3 and the transfer platform body 1 .

[0041] Preferably, the third transfer roller frame 9 can adopt the same structure as the first transfer roller frame 5 and the second transfer roller frame 7, and can be used to assist the rolling conveying of the first transfer roller frame 5 and the second transfer roller frame 7 to ensure the conveying process of the furnace charge.

[0042] Please see attached Figure 1 , the working process and working principle of the utility model are:

[0043] One end of the transfer platform body 1 is located at the charge loading port of the front chamber of the multi-furnace production line. The charge can be loaded onto the first transfer roller frame 5, the third transfer roller frame 9 and the starting end of a pair of first conveyor chains 3. The first reduction motor 4 is started, and the first reduction motor 4 synchronously drives the pair of first conveyor chains 3 for transmission.

[0044] The charge is conveyed to the second transfer roller frame 7 by a pair of first conveyor chains 3 . During this process, the rollers on the first transfer roller frame 5 and the third transfer roller frame 9 rotate to assist the conveyance of the charge until the charge is conveyed to the second transfer roller frame 7 .

[0045] Preferably, a first limit switch may be provided in the middle of the first transfer roller frame 5, and a first limit switch trigger may be provided on the first conveyor chain 3. When the first conveyor chain 3 is transferred to the first limit switch trigger to trigger the first limit switch, the charge is conveyed to the second transfer roller frame 7, and the first conveyor chain 3 completes the first stage of conveying the charge. At this time, the first limit switch sends an electrical signal to the second reduction motor to trigger the start of the second reduction motor.

[0046] The second reduction motor starts, and the second reduction motor synchronously drives the pair of second conveyor chains 6 to transmit, and the furnace charge continues to move forward through the pair of second conveyor chains 6, and the rollers on the second transfer roller frame 7 and the third transfer roller frame 9 rotate to assist the transportation of the furnace charge. While the pair of second conveyor chains 6 are transmitting, the transfer pusher frame 2 is driven by the pusher head 601 to move toward the front chamber feeding mechanism of the multi-furnace production line. While the transfer pusher frame 2 moves, it is lifted upward by the slope surface of the guide boss 101, so that the furnace charge is transferred to the transfer pusher frame 2 and is synchronously transported to the front chamber feeding mechanism with the transfer pusher frame 2.

[0047] Preferably, a third limit switch can be respectively set at both ends of the second transfer roller frame 7, and a second limit switch trigger can be set at one end of a pair of second conveyor chains 6. When the second limit switch trigger is located in the middle of the transfer platform body 1, i.e., the beginning of the second transfer roller frame 7, the pair of second conveyor chains 6 is in the initial state, and when the second limit switch trigger of the pair of second conveyor chains 6 runs to the other end of the transfer platform body 1, the second limit switch trigger triggers the third limit switch at the end of the second transfer roller frame 7, and the pair of second conveyor chains 6 push the beginning of the transfer pusher 2 from the middle of the transfer platform body 1 to the other end, and the transfer pusher 2 moves into place and conveys the furnace charge into place. At this time, the third limit switch at the end sends an electrical signal to the second reduction motor, drives the output shaft of the second reduction motor to rotate in the opposite direction, and drives the pair of second conveyor chains 6 to drive in the opposite direction, so that it drives the beginning of the transfer pusher 2 from the other end of the transfer platform body 1 back to the middle. At this time, the second limit switch triggering member triggers the third limit switch at the beginning of the second transfer roller frame 7, and the third limit switch at the beginning sends an electrical signal to the second reduction motor to turn off the second reduction motor.

[0048] During the transmission of the second conveyor chain 6, the first reduction motor 4 continues to drive the pair of first conveyor chains 3 to transmit, and the pair of first conveyor chains 3 completes a cycle transmission, and the first reduction motor 4 stops running after returning to the initial state. Since the transmission direction of the pair of first conveyor chains 3 is the same as that of the pair of second conveyor chains 6, the transmission of the furnace charge will not be affected.

[0049] Preferably, a second limit switch of the first conveyor chain 3 can be set at the starting end of the first transfer roller frame 5. When the first conveyor chain 3 is transmitted to the first limit switch triggering member to trigger the second limit switch, the first conveyor chain 3 completes a cycle transmission and returns to the initial state. At this time, an electrical signal can be sent to the first reduction motor 4 through the second limit switch to control the first reduction motor 4 to shut down.

[0050] Preferably, the three limit switches and their corresponding limit switch triggers may adopt contact limit switches or inductive contact limit switches of the prior art, which are used to trigger induction and generate corresponding electrical signals, thereby utilizing the electrical signals to realize the control function of the reduction motor.

[0051] After the charge is moved to the front chamber feeding mechanism through the transfer pusher 2, the charge conveying is completed. The second reduction motor synchronously drives a pair of second conveying chains 6 to drive in the reverse direction, so that the pair of second conveying chains 6 drive the transfer pusher 2 to move away from the front chamber feeding mechanism through the pusher head 601 and reset, and descend to below the second transfer roller frame 7 under the guidance of the slope surface of the guide boss 101, completing a charge conveying process.

[0052] By repeating the above process, continuous transportation of the charge between the charge loading port of the antechamber of the multi-furnace production line and the antechamber feeding mechanism can be achieved without manual transportation or suspending production during the transportation process.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
