Abstract
Description
(1)Technical Field
[0002] The utility model belongs to the technical field of metal sheet conveying, and particularly relates to a cross - workshop transfer device for metal sheet pretreatment. (2)Background Art
[0004] After the metal sheet is rolled, it needs to go through a shot - blasting process to remove the surface scale, and a straightening process to improve the flatness of the sheet and release the residual stress, and then proceed with the subsequent blanking process. In the actual production process, due to the limited layout space of the workshop, it is difficult to arrange sheet pretreatment equipment such as shot - blasting machines, straightening machines, and blanking equipment in one - span workshops. It is often necessary to arrange them in adjacent two - span or three - span workshops for cross - workshop layout. During the cross - workshop transfer process of the sheet, the overhead crane is used to transfer the sheet from the discharge roller table of the processing equipment in this workshop to the ground - rail trolley in the cross - workshop. The ground - rail trolley transports the sheet to the adjacent processing workshop, and then the overhead crane in this workshop hoists the sheet onto the loading roller table of the corresponding processing equipment. Such repeated hoisting consumes manpower, material resources, and time, and affects the improvement of the automation level of the pretreatment production line. (3)Summary of the Invention

(V) Specific implementation manner
[0029] The attached drawing is a specific embodiment of the present utility model. This embodiment is composed of multiple groups of transfer trolleys 2 with the same structure. The transfer trolley 2 has a lifting and moving platform capable of realizing automatic lifting and lateral movement actions. The lateral movement actions of multiple groups of transfer trolleys 2 are controlled by a unified lateral movement power system to achieve synchronous actions. The synchronous operation of multiple groups of transfer trolleys 2 is beneficial to the transfer of longer sheet materials 30. Multiple groups of transfer trolleys 2 are arranged alternately with the on-site loading and unloading roller path 1. When the floating platform 8 drops to the lowest point, the top surface height thereof is lower than the conveying working height of the loading and unloading roller path 1, without affecting the normal loading and unloading actions of the roller path 1.
[0030] The reduction motor 18 is fixed on the equipment foundation. One sprocket shaft 15 corresponds to one end of each transfer trolley 2. Each sprocket shaft 15 is fixed to one end of the transfer trolley 2 through two pedestal bearings 16. The reduction motor 18 and the sprocket shafts 15, and between the sprocket shafts 15 are connected in series in sequence by using the transmission shaft 17, and all the sprocket shafts 15 are driven to rotate by the reduction motor 18.
[0031] The tail of the oil cylinder 14 is hinged to the fixed frame body 3 through a pin shaft, and the piston rod hinge head of the oil cylinder 14 is hinged to the sprocket seat 12 through a pin shaft; the sprocket 11 is installed on the pin shaft of the sprocket seat 12 through a bearing, and the sprocket 11 can rotate; the sprocket seat 12 is installed in the guiding groove 13 of the fixed frame body 3, and the sprocket seat 12 is driven to slide in the guiding groove 13 by the telescopic movement of the piston rod of the oil cylinder 14.
[0032] The fixed frame body 3 is the frame foundation of the transfer trolley 2, and is provided with a horizontal guide rail 20 for the transverse movement of the transverse movement platform 4. The transverse movement platform 4 transversely moves along the horizontal guide rail 20 through the gear train 7. The oil cylinder 14 controls the lifting action of the floating platform 8 through the chain 10, and the reduction motor controls the transverse movement action of the transverse movement platform 4 through the chain 10.
[0033] The transverse movement platform 4 is composed of two relatively fixed guiding vertical plates 5. The two guiding vertical plates 5 are fixed in position by bolts 24 and spacer sleeves 25. The gear train 7 is used to position the guiding vertical plates 5, so that a lifting guide rail is formed in the space between the two guiding vertical plates 5. The floating platform 8 is arranged in the lifting guide rail and can be lifted in the lifting guide rail. Grooves for avoiding the bolts 24 and spacer sleeves 25 are machined on the floating platform 8. Multiple sets of gear trains 7 are provided on the transverse movement platform 4, and the transverse movement platform 4 moves along the horizontal guide rail 20 of the fixed frame 3 through the gear trains 7. The gear train 7 is composed of a wheel 19, a wheel shaft 6, a bearing 21, a first positioning ring 27, a second positioning ring 28, a shaft retaining ring 22, a hole retaining ring 23, and a lifting guiding bearing 26. The wheel 19 is positioned on the wheel shaft 6 through the bearing 21, the shaft retaining ring 22, and the hole retaining ring 23, and is positioned relative to the transverse movement platform 4 in the axial direction of the wheel shaft 6 through the first positioning ring 27, the second positioning ring 28, and the lifting guiding bearing 26. The structure of the gear train 7 is also used to position the two guiding vertical plates 5 of the transverse movement platform 4.
[0034] The floating platform 8 is provided with lifting guiding grooves 9, and the position and quantity are in one-to-one correspondence with the gear trains 7 of the transverse movement platform 4, and can be lifted along the direction of the lifting guiding grooves 9 relative to the axis of the gear trains 7 through the lifting guiding bearings 26.
[0035] One end of the chain 10 is connected to the lower part of the front of the floating platform 8, and after winding around the sprocket shaft 15 and the sprocket 11, the other end is connected to the lower part of the rear of the transverse movement platform 4. When the piston rod of the oil cylinder 14 extends, the center distance between the sprocket shaft 15 and the sprocket 11 becomes larger, the chain 10 is stressed and tightened, pulling the floating platform 8 to rise relative to the transverse movement platform 4. After rising, the upper surface of the floating platform 8 is higher than the conveying height of the roller path 1. The rising action of the floating platform 8 occurs when its position is below the roller path 1 where the plate 30 is placed. As the floating platform 8 rises, the position of the plate 30 on the roller path 1 rises, and the plate 30 is separated from the roller path 1 and is completely supported by multiple sets of floating platforms 8. The reduction motor 18 drives the sprocket shaft 15 to rotate, driving the chain 10 to rotate, and the chain 10 pulls the floating platform 8 and the transverse movement platform 4 to move horizontally together, driving the plate 30 to move to another row of roller paths 1.
[0036] The bottom of the floating platform 8 and the bottom of the transverse movement platform 4 are connected together by a tension spring 29. After the floating platform 8 rises, the tension spring 29 is stretched, generating a pulling force to pull the floating platform 8 back to the low point. When the piston rod of the oil cylinder 14 retracts when the plate 30 moves above the other row of roller paths 1, under the action of the pulling force of the tension spring 29 and the self-weight of the floating platform 8, the floating platform 8 falls back to the original position, and the plate 30 falls onto the roller path 1. The reduction motor 18 drives the sprocket shaft 15 to rotate in the reverse direction, and the floating platform 8 and the transverse movement platform 4 return to the original position, and the transfer process of the plate 30 ends.
