Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel transportation, and particularly relates to a horizontal transfer machine for feeding and discharging steel plates. BACKGROUND

[0002] The horizontal transfer machine (or horizontal transfer rack) is used for horizontally conveying steel plates that need to be horizontally transferred on a production line, and is applied to a metallurgical hot rolling or medium plate production line, a horizontal and vertical cutting production line and a heat treatment production line.

[0003] At present, since the width range of the transported steel plates is large, in order to ensure that the center of gravity of the steel plate falls within the chain area during lifting, the chain wheel on the swing arm is generally designed outside the roller bed, so that the center of gravity of the steel plate can fall within the chain area regardless of the width of the steel plate. However, this structure requires the swing arm to cross above the roller bed frame, resulting in the need to open a gap in the roller bed frame, which affects the strength and rigidity of the roller bed frame. The chain also needs to cross above and below the roller bed frame, and the chain has a suspension, causing the roller bed frame in this area to be very high, further affecting the strength and rigidity of the roller bed frame. The chain bracket below the swing arm is difficult to design and fix, the chain suspension is large, and the suspension degree of each chain is different. When the steel plate is horizontally transferred, the "jerking" phenomenon occurs, causing the steel plate to deviate and the lower surface of the steel plate to be scratched. SUMMARY

[0004] The utility model provides a horizontal transfer machine for feeding and discharging steel plates to solve the problem of safety influence caused by the existing feeding and discharging device due to the need to open a gap in the roller bed frame and the suspension of the chain.

[0005] The technical scheme of the utility model is: a horizontal transfer machine for feeding and discharging steel plates, comprising a swing arm, a first bearing seat, a second bearing seat and a roller bed, the roller bed and the swing arm are arranged at intervals, the swing arm swings up and down by rotating around a hinge point, further comprising a chain wheel, the chain wheel is installed at the free end of the swing arm, the chain wheel is located between the first bearing seat and the second bearing seat, and the swing arm and the chain wheel are jointly installed with a chain.

[0006] As a further improvement of the utility model, a rotating shaft is arranged on the swing arm, a driving rotary arm and a driven rotary arm are connected to the rotating shaft, the driving rotary arm is connected to a transmission machine through the swing arm, the rotary arm is rotationally connected to the swing arm, and the driven rotary arm is rotationally connected to the swing arm.

[0007] As a further improvement of the utility model, a chain bracket is arranged below the swing arm, the chain bracket is connected to the swing arm through a connecting column, and the lower chain is arranged on the chain bracket.

[0008] The utility model discloses a beneficial effect: the utility model discloses through changing the position and the direction of swing arm of chain wheel, make swing arm not need to pass through the roller way frame, swing arm is in the roller way inboard, need not cross roller way frame top, therefore, the roller way frame need not open the gap, can be installed directly on the foundation, and the strength and rigidity of roller way frame are guaranteed, and the roller way frame height is reduced, and the length of chain and swing arm is reduced, and the equipment investment is reduced.

DETAILED DESCRIPTION

[0014] The utility model will be further explained in detail in connection with the drawings and specific embodiment.

[0015] Prior art as shown in Figure 2 It includes swing arm 1, first bearing seat 4, second bearing seat 5 and roller way 9, and roller way 9 and swing arm 1 are arranged at intervals, swing arm 1 swings up and down by rotating around hinge point 6, and chain wheel 2 is located on the outside of roller way 9, but therefore the original transmission assembly will pass through second bearing seat 5, which affects the stability of second bearing seat 5.

[0016] As shown in Figure 1 A steel sheet feeding and discharging transverse moving conveyor, including chain wheel 2, chain wheel 2 is installed at the free end of swing arm 1, chain wheel 2 is located between first bearing seat 4 and second bearing seat 5, and chain 3 is installed on swing arm 1 and chain wheel 2.

[0017] The swing arm 1 is provided with a rotating shaft 13 below, the rotating shaft 13 is connected with a driving rotary arm 11 and a passive rotary arm 12, the driving rotary arm 11 is connected with the transmission mechanism 10 through a swing arm 14, the rotary arm 11 is rotationally connected with the swing arm 14, and the passive rotary arm 12 is rotationally connected with the swing arm 1.

[0018] The swing arm 1 is provided with a chain bracket 7 below, the chain bracket 7 is connected with the swing arm 1 through a connecting column 15, and the chain 3 below is arranged on the chain bracket 7.

[0019] Before the steel plate 8 enters the feeding area, the chain 3 is in a waiting position, i.e. a low position, the roller way 9 is in the same horizontal plane as the chain 3 in the low position, and the surface of the chain 3 is a certain distance away from the surface of the roller way 9, so as to facilitate the roller way 9 to convey the steel plate 8 to be fed into the area.

[0020] As shown in the figure, Figure 3 When the conditions are met, the rollers of the roller way 9 rotate to drive the steel plate 8 on the roller way 9 to transport downstream along the conveying direction and enter the feeding area. When the system detects that the tail of the steel plate 8 enters the feeding area, the rotation of the roller way 9 is stopped, and the steel plate 8 is stopped on the surface of the roller way 9, the center of gravity N of the conveyed steel plate 8 does not exceed the center surface M of the sprocket 2, so as to ensure the success of the lifting of the steel plate. Subsequently, the transmission 10 of the feeding device starts to act to drive the driving rotary arm 11 to rotate around the rotating shaft 13, and the passive rotary arm 12 rotates around the rotating shaft 13, the end of the passive rotary arm 12 is provided with a roller, and the passive rotary arm 12 drives the swing arm 1, the sprocket 2 and the chain 3 on the swing arm 1 to rise together in the lifting process.

[0021] As shown in the figure, Figure 4 When the swing arm 1 rises to the high position, the surface of the chain 3 on the swing arm 1 is higher than the roller surface of the roller way 9, so the steel plate 8 is lifted to the highest position by the chain 3 and leaves the surface of the roller way 9, when the system detects that the swing arm 1 has reached the highest position, the power driving the chain 3 transports the steel plate 8 transversely downstream. When the system detects that the steel plate 8 has left the lifting range of the swing arm 1, the transmission 10 of the feeding device is restarted to drive the swing arm 1 to descend to the lowest position, i.e. the waiting position, through the driving rotary arm 11, the rotating shaft 13 and the passive rotary arm 12, and a feeding cycle process is completed.

[0022] The unloading is the reverse action of the feeding, the swing arm 1 is lifted to the highest position, the steel plate 8 can be moved transversely, the swing arm 1 is driven to descend through the driving rotary arm 11, the rotating shaft 13 and the passive rotary arm 12, so that the steel plate 8 is in contact with the roller way 9, the rollers of the roller way 9 rotate reversely to drive the steel plate 8 to transport along the roller way 9, after the steel plate 8 enters the roller way 9 completely, the swing arm 1 is driven to descend to the lowest position, i.e. the waiting position, through the driving rotary arm 11, the rotating shaft 13 and the passive rotary arm 12, and a unloading cycle process is completed.
