[0002] During the processing of steel coils, they need to go through processes such as uncoiling, flattening, shearing, and welding. In the actual production process, the uncoiling steel coil needs to be turned over so that the central axis of the steel coil is parallel to the ground and it is in an upright state for subsequent processing.

[0003] Traditionally, steel coils are usually turned over by lifting equipment or manually. The lifting and turning method of lifting equipment requires manual assistance in lifting and positioning. Although this method can meet the requirements, the lifting and turning of steel coils is cumbersome and the turning efficiency is low. In the manual turning method, due to the heavy weight of the steel coils, there are certain safety hazards during the operation of workers, the labor intensity is high, and it is time-consuming and labor-intensive, which affects production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model is further described in detail below through specific implementation methods:

[0017] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a steel coil turning device, comprising a support frame 1, a turning frame 2 and a guide assembly 3; wherein the turning frame 2 is arranged on the top of the support frame 1 and is driven by a driver 4 to turn between a first state and a second state; the guide assembly 3 is connected between the support frame 1 and the turning frame 2 and is used for guiding during the turning of the turning frame 2, and an adjustable anti-return assembly 5 is provided on the guide assembly 3, and the adjustable anti-return assembly 5 is used to limit the reverse movement of the guide assembly 3 when the turning frame 2 turns from the first state to the second state.

[0018] When in use, the turning frame 2 is in the first state on the supporting frame 1. At this time, the steel coil is placed on the turning frame 2 by a forklift, and the rear driver 4 moves to turn the turning frame 2, and the turning frame 2 turns from the first state to the second state to complete the turning of the steel coil; during this process, the guide assembly 3 guides the turning of the turning frame 2 to ensure that the turning frame 2 is more stable during the turning from the first state to the second state. At the same time, the adjustable anti-return assembly 5 cooperates to avoid limiting the reverse movement of the guide assembly 3, thereby improving the stability of the turning frame 2 from the first state to the second state; after the turning is completed, the steel coil is removed from the turning frame 2 by a forklift.

[0019] The restriction of the adjustable anti-return component 5 on the guide component 3 is released, and the rear driver 4 moves in the reverse direction to drive the turning frame 2 to turn in the reverse direction. The turning frame 2 turns back from the second state to the first state. The guide component 3 still guides this process. After the turning frame 2 returns to the first state, the next steel coil can be turned over.

[0020] In order to better understand the present solution, the structures of the support frame 1, the turning frame 2 and the guide assembly 3 will be optimized below.

[0021] like Figure 1 , Figure 2 as well as Figure 3 As shown, according to another embodiment of the utility model, a steel coil turning device, wherein the guide assembly 3 includes an arcuate guide bar 31, wherein there are multiple arcuate guide bars 31 and one end of each of the arcuate guide bars 31 is fixedly connected to the turning frame 2, and the other end of each of the arcuate guide bars 31 is slidably connected to the support frame 1, and at least one arcuate guide bar 31 is cooperated with the adjustable anti-return assembly 5.

[0022] In this embodiment, there are at least two arc-shaped guide bars 31, which are arranged in parallel and spaced apart on one side of the flip frame 2 to make the flip frame 2 more stable during the flipping process; and each arc-shaped guide bar 31 is provided with the adjustable anti-return component 5 to make the flip frame 2 more capable of limiting the reverse movement of the guide component 3 when flipping from the first state to the second state.

[0023] The center of the circle where each arc-shaped guide strip 31 is located falls on the rotation point of the turning frame 2 during the turning process, so that the arc-shaped guide strip 31 can stably guide the turning frame 2 without causing any restriction.

[0024] Based on the above scheme:

[0025] Each of the adjustable non-return components 5 includes an arcuate ratchet bar 51 and a pawl 52, wherein the arcuate ratchet bar 51 is arranged along the designed path of the arcuate guide bar 31 with which it cooperates; the pawl 52 cooperates with the arcuate ratchet bar 51 and the pawl 52 is cooperated with an adjustment portion 53, and the adjustment portion 53 is used for the pawl 52 to disengage or maintain cooperation with the arcuate ratchet bar 51.

[0026] In this embodiment: the arc-shaped guide strip 31 has an arrangement groove on its side wall along its designed path, and the arc-shaped ratchet strip 51 is formed by a plurality of ratchets arranged in the arrangement groove along the direction of its designed path.

[0027] Specifically, the working end of the pawl 52 extends into the arrangement groove to cooperate with the arc-shaped ratchet bar 51 formed by a plurality of ratchets, the structure of the arc-shaped guide bar 31 is reasonably utilized, and the arrangement groove is used to improve the assembly stability between the pawl 52 and the arc-shaped ratchet bar 51; when the turning frame 2 rotates from the first state to the second state, the adjustment part 53 is used to keep the pawl 52 and the arc-shaped ratchet bar 51 in cooperation, and the arc-shaped guide bar 31 rotates with the turning of the turning frame 2. The cooperation between the pawl 52 and the arc-shaped ratchet bar 51 will not restrict the rotation of the arc-shaped guide bar 31, but will restrict the reverse rotation of the arc-shaped guide bar 31, thereby ensuring that the turning frame 2 is more stably turned from the first state to the second state, and ensuring the stability of the steel coil during the turning process.

[0028] Before the flip frame 2 flips back to the first state from the second state, the adjustment portion 53 is required to disengage the pawl 52 from the arcuate ratchet bar 51 to avoid the pawl 52 and the arcuate ratchet bar 51 from restricting the arcuate guide bar 31, thereby ensuring that the flip frame 2 can complete the flipping from the second state back to the first state.

[0029] Furthermore, the adjustment part 53 includes a mounting shell 531, an elastic support member 532, an adjustment iron block 533 and an energized solenoid 534. The mounting shell 531 is fixedly connected to the support frame 1 and is slidably connected to the corresponding arc-shaped guide strip 31. A first cavity and a second cavity are sequentially arranged in the mounting shell 531 in a direction away from the arc-shaped ratchet strip 51; the elastic support member 532 is arranged in the first cavity and is connected to the pawl 52, the adjustment iron block 533 is slidably arranged in the second cavity and is fixedly connected to the pawl 52, the energized solenoid 534 is arranged in the second cavity and is arranged opposite to the adjustment iron block 533, and a movable space is left between the adjustment iron block 533 and the energized solenoid 534.

[0030] Here, the elastic support member 532 may be a plurality of springs disposed in the first cavity and connected to the pawl 52, which can keep the pawl 52 in cooperation with the arcuate ratchet bar 51 on one hand, and can drive the pawl 52 to reset and cooperate with the arcuate ratchet bar 51 again when the pawl 52 and the arcuate ratchet bar 51 are out of cooperation and need to be cooperated again on the other hand. When the flip frame 2 is flipped from the first state to the second state, the energized solenoid 534 is not energized, there is no adsorption force between the regulating iron block 533 and the energized solenoid 534, and the spring is in an expanded state, so that the pawl 52 and the arcuate ratchet bar 51 are kept in cooperation, and the arcuate guide bar 31 can only rotate with the flip frame 2 from the first state to the second state. When the flip frame 2 needs to flip back to the first state from the second state, the energized solenoid 534 is energized first. The energized solenoid 534 is magnetic. The energized solenoid 534 adsorbs the adjusting iron block 533 to make the adjusting iron block 533 move toward the energized solenoid 534 until they are adsorbed together. During the movement, the adjusting iron block 533 drives the pawl 52 to move away from the arc ratchet bar 51. The pawl 52 is disengaged from the arc ratchet bar 51, and the springs are in a compressed state. At this time, the driver 4 can drive the flip frame 2 to flip back to the first state from the second state without restriction. Specifically, the adjusting iron block 533 and the pawl 52 are connected by a connecting rod freely arranged between the first cavity and the second cavity. After the flip frame 2 flips back to the first state from the second state, the energized solenoid 534 can be de-energized, and the spring is reset to make the adjusting iron block 533 and the pawl 52 slide in the opposite direction to reset, and the pawl 52 is matched with the arc ratchet bar 51 again.

[0031] In order to better control the energization of the energized solenoid 534, as Figure 1 , Figure 2 as well as Figure 4 As shown, according to another embodiment of the utility model, in the steel coil turning device, a control component 6 for controlling the power on or off of the energized solenoid 534 is arranged between the turning frame 2 and the supporting frame 1.

[0032] Specifically, the control assembly 6 includes a trigger column 61 and a touch-pressure switch 62. There are two trigger columns 61 and both are connected to the flip frame 2.

[0033] There are two touch pressure switches 62 and both are arranged on the support frame 1. The two touch pressure switches 62 cooperate with the energized solenoid 534. When the flip frame 2 is in the first state, one of the trigger columns 61 contacts and cooperates with one of the touch pressure switches 62. When the flip frame 2 is in the second state, the other trigger column 61 contacts and cooperates with the other touch pressure switch 62.

[0034] When the flip frame 2 flips from the first state to the second state, the trigger column 61 moves with the flip frame 2 to make one of them contact and cooperate with one of the touch-pressure switches 62. At this time, the energized solenoid 534 is energized, and the pawl 52 is disengaged from the arc-shaped ratchet bar 51; then, when the flip frame 2 flips from the second state back to the first state, the trigger column 61 moves with the flip frame 2 to make the other one contact and cooperate with the other touch-pressure switch 62. At this time, the energized solenoid 534 is de-energized, and the pawl 52 is engaged with the arc-shaped ratchet bar 51 again; the adjustment process is convenient and quick.

[0035] Specifically, the power supply, the energized solenoid 534 and the two touch-pressure switches 62 are connected to form an existing double-open control circuit.

[0036] Furthermore, each of the touch-pressure switches 62 is matched with a mounting groove 8 provided on the top of the support frame 1, and the touch-pressure switch 62 is arranged in the corresponding mounting groove 8. Since the top of the support frame 1 is a plane, the mounting groove 8 provides an installation space for the touch-pressure switch 62 for protection, so as to prevent the touch-pressure switch 62 from being damaged during the flipping process of the flip frame 2.

[0037] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, a steel coil turning device is described, wherein the turning frame 2 is "L"-shaped, so that the steel coil can be placed on the turning frame 2, and the turning frame 2 is driven to rotate by the driver 4 to complete the turning of the steel coil.

[0038] The two trigger posts 61 are arranged one by one on the outer sides of the two sections of the flip frame 2 . When the flip frame 2 is flipping, the two trigger posts 61 cooperate with the two touch switches 62 one by one.

[0039] In order to improve the placement stability of the steel coil on the turning frame 2, limit blocks 7 are provided on both sides of the turning point of the turning frame 2 to prevent the steel coil from sliding out from both sides of the turning frame 2 during the turning process of the turning frame 2.

[0040] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, a steel coil turning device, wherein the driver 4 can be a stepping motor, the top surface of the support frame 1 is fixedly arranged on mounting seats on both sides, and a rotating shaft connected to the turning frame 2 is rotatably connected between the two mounting seats, and one end of the rotating shaft is connected to the stepping motor.

[0041] The stepper motor is started to drive the turning frame 2 to turn over through the rotating shaft.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
