A platform frame transfer tray tooling

Abstract

The application discloses a platform frame transfer tray tool, which comprises a storage fence and a tray part. The inside of the storage fence is formed with a containing space, and the tray part supports the storage fence from the bottom of the storage fence. The bottom of the storage fence is provided with a supporting position adjusting mechanism, which is used for adjusting the supporting position to make it close to the balance point of the storage fence. The tray part comprises a tray body and a counterweight rocker plate. The middle part of the counterweight rocker plate is hinged to the middle part of the tray body. The storage fence can greatly increase the transverse storage space of the forklift, and the containing space is used to contain the platform frame with large span. When the span of the forked object is increased to exceed the width of the tray, and the weight of the platform frame is unevenly distributed, the counterweight rocker plate can quickly sense when the balance point of the forked object is far away from the middle point of the platform frame, and the supporting position adjusting mechanism can adjust the supporting position of the storage fence, so that the supporting position of the forklift is close to the balance point of the storage fence, thereby ensuring the stability and safety in the transfer process.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] A platform rack pallet transfer fixture, such as Figure 1 As shown, the device includes a storage rack 1 and a pallet section 2. The storage rack 1 forms an internal accommodating space. The length of the storage rack 1 in this invention significantly exceeds the width of the pallet section 2, allowing for the placement of large-span platform frames within its accommodating space. Furthermore, the storage rack 1 has a high fence, effectively enclosing the internal platform frames and accommodating them. It is understood that the length of the storage rack 1 in this device can be increased according to the span of the platform frames, thus accommodating the storage of platform frame iron outfitting components with larger spans. Traditionally, platform frame iron outfitting components are stored by direct stacking. Therefore, during ship outfitting, these platform frame iron outfitting components need to be repeatedly moved. Directly stacked platform frames are difficult to lift with forklifts, making the transfer of platform frame iron outfitting components difficult and usually requiring hoisting operations for transportation. In this invention, a storage bar 1 is used to store the iron outfitting components of the platform frame, and the bottom center of the storage bar 1 is off the ground, so the platform frame can be directly lifted and transported by the pallet part 2, which lifts it from the bottom of the storage bar 1.

[0030] This way, firstly, it can be orderly stored when facing the platform frame storage, and the platform frame is supported away from the ground by the storage column 1, which can also avoid the erosion of the platform frame by water stains and other impurities on the ground; Secondly, it can form a protective enclosure around the fence to ensure safety. Although it has the above advantages, there are still some problems in directly using a forklift to pick up the storage column 1, for example, the platform frame iron fittings stored in the storage column 1 have a large span and extend to the outside of the tray part 2 on both sides, and even larger iron fittings will further increase the span of the storage column 1. When lifting using the tray part 2, due to the large span, the weight distribution of the platform frame iron fittings is uneven when stored in the storage column 1 due to the structure and other reasons, which causes the center of gravity of the storage column 1 to deviate from the midpoint of the storage column 1 by a large distance. If the tray part 2 is still lifted in the middle position of the storage column 1 when lifting, it is easy to tip over. In order to solve this problem, the present application is provided with a supporting position adjusting mechanism 3 at the bottom of the storage column 1, which is used to adjust the lifting position to be close to the balance point of the storage column 1, so that the tray part 2 can be lifted directly on the supporting position adjusting mechanism 3 each time to maximize the balance of the storage column 1.

[0031] Specifically, the supporting position adjusting mechanism 3 includes a supporting plate 6, which is adjustably and slidably connected with the lower end surface of the storage column 1, and is used to move or position the lifting position of the storage column 1. In actual use, the tray part 2 directly aligns with the supporting plate 6 to lift the storage column 1, so that the wings can be balanced to the maximum extent each time the storage column 1 is lifted. The adjustment of the supporting plate 6 is to move the supporting plate 6 towards the center of gravity of the storage column 1 and fix the position, and specifically, as shown in Figure 2 、 3 , a guide rail 7 is arranged at the lower end surface of the storage column 1, and a sliding block is arranged on the supporting plate 6 and slidably connected with the guide rail 7. The guide rail 7 and the sliding block can easily slide the supporting plate 6 relative to the storage column 1 to adjust the position. In this embodiment, the guide rail 7 is arranged along the length direction of the storage column 1, so that the supporting plate 6 can be moved and adjusted along the length direction of the storage column 1. If the center of gravity is on the left side, the supporting plate 6 is moved to the left, and vice versa.

[0032] Further, the supporting position adjusting mechanism 3 further includes a transverse adjustment part for adjusting the position of the supporting plate 6, which is a driving mechanism for driving the supporting plate 6 to move relative to the storage column 1, as shown in Figure 2 、 3As shown, it includes a first rack 8, a first gear 9, a drive handwheel 10, a transmission rod 11, and a steering mechanism 12. The lateral adjustment part is disposed between the storage bin 1 and the tray 6. The first rack 8 is fixedly disposed on the lower end face of the storage bin 1. The gear meshes with the rack. The steering mechanism 12 is fixedly disposed on the tray 6. The steering mechanism 12 is connected to drive the first gear 9 through the transmission rod 11. The drive handwheel 10 is connected to the input end of the steering mechanism 12, and the drive handwheel 10 drives the first gear 9 to rotate in one direction. As one embodiment, such as... Figure 3 As shown in the figure, the tooth surface of the first rack 8 can be designed as a worm gear rack, and the first gear 9 can be a worm. The meshing of the worm and the worm gear rack can realize the unidirectional transmission of force. The first gear 9 drives the first rack 8 to move and will not drive it in the opposite direction. In this embodiment, there are two transmission rods 11. One is directly connected to the first gear 9, and the other is set at 90° with the first one. The two transmission rods 11 are connected to each other through a steering mechanism 12 to realize transmission. A drive handwheel 10 is set at a convenient position on the support plate 6, so as to control the rotation of the first gear 9 through the drive handwheel 10. As another embodiment, the first rack 8 is set in the same form, and the first gear 9 can be a spur gear. The two are meshed at 90 degrees. In this embodiment, a transmission rod 11 can be set. The first gear 9 is set at one end of the transmission rod 11, and a steering mechanism 12 is set at the other end. In this embodiment, the steering mechanism 12 can be a worm gear reducer, so as to ensure the unidirectional transmission of force and realize the control of the position of the guide rail 7. A drive handwheel 10 is set at the input end of the steering mechanism 12.

[0033] However, in actual lifting of the storage bin 1, it is impossible to accurately know the center of gravity of the storage bin 1. Instead, the position of the support plate 6 is adjusted by visual inspection and feeling to bring it as close to the center of gravity as possible to achieve lifting close to the balance point. However, visual inspection alone has a large error and cannot achieve precise adjustment. As an improvement, such as Figure 1 , 4 As shown, in this embodiment, the pallet section 2 is configured as a pallet body 4 and a counterweight rocker 5. The counterweight rocker 5 is hinged to the middle of the pallet body 4. The pallet section 2 lifts the storage rack 1 through the counterweight rocker 5 and the positioning adjustment mechanism 3. In actual use, the pallet section 2 is used to test lift the storage rack 1. After visually adjusting the position of the pallet 6, the pallet section 2 is used to lift the pallet 6, causing the storage rack 1 to leave the ground. Due to the counterweight rocker 5, the heavier end of the storage rack 1 will sink, forming a tilt. The counterweight rocker 5 allows for a direct visual inspection of whether the lifted part of the pallet 6 is balanced. If it is unbalanced, the pallet section 2 is lowered, and the position of the pallet 6 is adjusted again. The balance of both sides of the pallet 6 can be adjusted by multiple test lifts.

[0034] The above tray part 2 setting mode can be used for two purposes, not only for lifting and transferring the storage fence 1, but also for measuring the centroid position of the storage fence 1 through the balance tilting plate 5. However, the balance tilting plate 5 capable of pivoting will have a negative impact on the subsequent transfer process of the storage fence 1, that is, left and right shaking is easy to cause instability of the upper storage fence 1. As an improvement, as shown in Figure 4 The tray part 2 is also provided with a micro-displacement elastic support structure 16, which is arranged between the tray body 4 and the balance tilting plate 5 and distributed on both sides of the balance tilting plate 5. In this embodiment, four groups of micro-displacement elastic support structures 16 are provided and distributed at the four corner positions of the tray part 2.

[0035] Specifically, the micro-displacement elastic support structure 16 includes a disc spring 17 and a core column 18. The core column 18 is vertically fixedly arranged at the lower end surface of the balance tilting plate 5. The disc spring 17 is provided with a plurality of pieces, and the disc spring 17 is sleeved on the core column 18 in a stacked manner. The plurality of pieces of disc spring 17 are filled between the balance tilting plate 5 and the tray body 4, so that the balance tilting plate 5 and the tray body 4 are kept parallel. The elasticity of the disc spring 17 can be set according to the weight of the storage fence 1 to be lifted. If the storage fence 1 to be lifted is light, a disc spring 17 with a small elastic coefficient can be used, so that the balance tilting plate 5 can be pivoted more sensitively. Conversely, a disc spring 17 with a large elastic coefficient is used. In actual use, the balance tilting plate 5 is supported by the plurality of disc springs 17 stacked at the four corner positions so that it cannot be pivoted. In order to maintain the stability of the stacked disc springs 17, the disc springs 17 stacked at each corner position are fixed by being penetrated on the core column 18. Since the disc spring 17 can be deformed and the deformation amount of the disc spring 17 is small, the angle of rotation of the balance tilting plate 5 can be limited, so that it can only be rotated by a small amount. In this way, the balance of the storage fence 1 can be measured, and the storage fence 1 can be prevented from tilting during the transfer process, thereby ensuring safety.

[0036] And since the disc spring 17 can provide elastic support force within a certain range, it is used to tightly press the balance tilting plate 5 to limit its pivoting within the elastic support force threshold range, and to provide a small pivoting angle for the balance tilting plate 5 when the elastic support force threshold is exceeded; so that the supporting plate 6 has an adjustment range in actual use, avoiding repeated adjustment of the position of the supporting plate 6, making the adjustment more rapid,

[0037] Further, due to the arrangement of the micro-displacement elastic support structure 16, when the balance of the storage shelf 1 is measured, the side that is heavier cannot be determined by directly observing the deflection of the weight tilting plate 5; therefore, the pressure imbalance alarm device 13 is needed to perceive, specifically, the pressure imbalance alarm device 13 is provided with at least two groups and is arranged on both sides of the weight tilting plate 5, the pressure imbalance alarm device 13 comprises a pressure sensor 14 and a pressure column 15, the pressure sensor 14 is fixedly arranged on the tray body 4, the pressure column 15 is arranged on the lower end surface of the weight tilting plate 5, and the lower end surface of the pressure column 15 is arranged towards the pressure sensor 14, when the pressure is imbalanced, the weight tilting plate 5 pivots to make the corresponding pressure column 15 abut against the pressure sensor 14, and the corresponding alarm is sent; when the weight tilting plate 5 is slightly rotated, the pressure sensor 14 can perceive the deflection of the weight tilting plate 5, that is, if one side of the weight tilting plate 5 is heavier, the pressure exceeds the threshold of the elastic force support of the disc spring 17 under the action of the pressure, the disc spring 17 is crushed, and then the corresponding side of the weight tilting plate 5 is sunken, the pressure is applied to the pressure sensor 14 by pressing, in actual use, a controller can be arranged in the tray part 2, the pressure sensor 14 is connected with the controller, the controller obtains the feedback information of the pressure sensor 14, and then the corresponding alarm can be controlled to send an alarm to the operator, so that the operator can intuitively adjust. In this way, the weight tilting plate 5 that is slightly rotated can be detected, and the weight tilting plate 5 only slightly rotates, which has little effect on the upper storage shelf 1, and the safe use can be ensured.

[0038] When the tray part 2 is used to lift and move the storage shelf 1, the tray part 2 needs to be positionally locked with the storage shelf 1 to avoid the accumulation of displacement of the storage shelf 1 and the tray part 2 due to bumping during the transfer process, and further cause the storage shelf 1 to be tilted and dumped, as an improvement, the automatic locking device 19 is arranged between the supporting plate 6 and the weight tilting plate 5, and the automatic locking device 19 limits and fixes the two when the weight tilting plate 5 lifts the supporting plate 6; and the automatic locking device 19 can also make the weight tilting plate 5 and the supporting plate 6 be positionally fixed each time, so as to avoid the error caused by the slight change of the lifting position during the weighing, specifically, Figure 4As shown, the automatic locking device 19 includes a transverse rack 20, a longitudinal rack 21, a supporting spring 22, a transmission gear 23, the tray 6 is provided with a rack track 24 for the sliding of the transverse rack 20, the back of the transverse rack 20 is provided with a T-shaped fixing nail 25, the balance weight flap 5 is provided with a long slot 26 for the movement of the fixing nail 25, when the transverse rack 20 moves in the rack track 24, the position of the fixing nail 25 along the long slot 26 can be controlled, when the balance weight flap 5 is aligned with the position of the clamping opening 27 on the side of the tray 6, then the transverse rack 20 is controlled to move, so that the fixing nail 25 is clamped into the clamping opening 27, and the balance weight flap 5 is connected and fixed with the tray 6 to form a limit. In order to automatically drive the fixing nail 25 to be clamped into the clamping opening 27, the longitudinal rack 21 is further provided, which is arranged on one side of the transverse rack 20 and vertically penetrates through the balance weight flap 5 and is slidingly connected. When the tray 6 is lifted by the forklift, the upper end of the longitudinal rack 21 first touches the bottom of the tray 6, so that the tray 6 presses downward the longitudinal rack 21 to move downward, and the downward movement of the longitudinal rack 21 drives the transverse rack 20 to move transversely, so that the fixing nail 25 is clamped into the clamping opening 27 to be fixed. Specifically, the longitudinal rack 21 and the transverse rack 20 are in transmission through the transmission gear 23, as shown in Figure 7 As shown, the transmission gear 23 is rotatably arranged on the balance weight flap 5 and is in meshing with the transverse rack 20 and the longitudinal rack 21, and the lower end of the longitudinal rack 21 is provided with the supporting spring 22 for lifting the longitudinal rack 21 to reset. When the storage rack 1 is not lifted, the upper end of the longitudinal rack 21 protrudes from the balance weight flap 5 by a certain length, which is provided by the upward lifting of the supporting spring 22. When lifting, the tray part 2 is placed below the tray 6 and is aligned, then the tray part 2 is lifted, the bottom surface of the tray 6 first presses on the longitudinal rack 21 and continues to press downward, along with the downward movement of the longitudinal rack 21, the transmission gear 23 is driven to rotate, and then the transverse rack 20 is controlled to move along the rack track 24, so that the fixing nail 25 is clamped into the clamping opening 27. When the balance weight flap 5 is attached to the tray 6, the fixing nail 25 is also clamped in the long slot 26 and the clamping opening 27, thereby fixing the two. It can be understood that the fixing nail 25 has a certain length, so as to be clamped into the clamping opening 27. The tray part 2 lifts the tray 6 to press the longitudinal rack 21, and the longitudinal rack 21 pulls the transverse rack 20 to clamp the fixing nail 25 into the clamping opening 27.

[0039] The side of the tray 6 is provided with a long slot 26, and the clamping opening 27 is provided on the side of the tray 6, and the clamping opening 27 and the long slot 26 are arranged in the same direction. Specifically, the clamping opening 27 and the long slot 26 are provided with at least four, and two are arranged on the tray insertion side, and the clamping opening 27 and the long slot 26 are parallel to the tray insertion direction. The other two are arranged on the two sides adjacent to the insertion side, and the clamping opening 27 and the long slot 26 are perpendicular to the insertion direction, as shown in Figure 4As shown, when the tray is attached to the counterweight rocker 5, all four fixing pins 25 move inward and lock into the slots 27 to form a fixation. Conversely, when the tray 2 falls and the counterweight rocker 5 leaves the support plate 6, the longitudinal rack 21 is lifted upward by the support spring 22, thereby controlling the fixing pins 25 to move in the opposite direction and release the fixation to the slots 27. This achieves automatic locking during lifting and automatic separation after lowering.

[0040] Furthermore, to ensure that the latch 27 and the elongated slot 26 are aligned before lifting, since the fixing pin 25 can only smoothly enter the latch 27 and complete the positioning when the latch and the elongated slot 26 are aligned, the automatic locking device 19 also includes an alignment structure. This alignment structure includes an alignment rod 28 and an alignment notch 29. In use, the forklift operator observes the alignment rod 28 aligning with the alignment notch 29 and then lowers it to align the latch 27 with the elongated slot 26. Therefore, both the alignment rod 28 and the alignment notch 29 are positioned for easy observation by the forklift operator. Specifically, the alignment notch 29 is located on the insertion side of the pallet 6, through which the pallet part 2 is inserted into its bottom. The alignment rod 28 is vertically mounted on the counterweight rocker 5. Figure 1 , 4 As shown, when the tray part 2 is inserted into the bottom of the tray 6, the tray 6 is aligned and connected with the counterweight rocker 5 by engaging the alignment rod 28 into the alignment notch 29.

[0041] Furthermore, the storage bar 1 is provided with lifting support wheel structure at its four corners. This structure is used to fix the position of the storage bar 1 after it is placed in place. When the forklift lifts the storage bar 1, the lifting support wheel structure can extend the rollers 31 to support the ground according to the lifting height, thereby improving the support of the storage bar 1.

[0042] like Figure 5 , 6 As shown, it includes a support cylinder 30, with casters at the bottom. When it is necessary to balance the storage rack 1 and adjust the position of the pallet 6, the support cylinder 30 extends to raise the height of the storage rack 1, providing sufficient operating space below the storage rack 1, thus facilitating the insertion of the pallet 2 from below the storage rack 1. It can be understood that the oil supply of the support cylinder 30 with lifting support wheel structure at the four corners can be achieved by connecting to the external oil supply pipe on the forklift through a quick interface via a retractable oil pipe to control the extension of the cylinder; alternatively, other external manual or electric hydraulic oil supply devices can be used to control the extension of the cylinder.

[0043] The universal wheel is provided with a position locking device, which comprises a roller 31, a reverse U-shaped wheel fork frame 32 and a locking piece 33; the roller 31 is rotationally connected in the wheel fork frame 32, the side wall of the roller 31 is provided with a plurality of uniformly distributed radial insertion grooves 34, the wheel fork frame 32 is provided with an insertion opening 35, the locking piece 33 is arranged on the upper side of the wheel fork frame 32 and can slide up and down, the locking piece 33 is provided with an insertion rod 36 corresponding to the position of the insertion opening 35, the insertion rod 36 is inserted into the insertion groove to limit the roller 31 when the locking piece 33 moves down; the locking piece 33 and the wheel fork frame 32 are provided with a jacking spring 37. In actual use, during the transportation of the supporting and storing fence 1, the supporting oil cylinder 30 can be elongated to make the roller 31 fall on the ground, thereby assisting in supporting the supporting and storing fence 1, at this time, the roller 31 can rotate freely, which is the same as the ordinary universal wheel; however, when the supporting and storing fence 1 is positioned, the roller 31 needs to be locked to avoid the movement of the supporting and storing fence 1. It can be understood that the lifting and supporting wheel structure is completely retracted and the locking piece 33 is pressed down during positioning, so that the insertion rod 36 is inserted into the inside of the wheel fork frame 32 from the position of the insertion opening 35, and the insertion rod 36 can be inserted into the radial insertion groove 34 on the side of the roller 31, thereby realizing the automatic limitation of the rotation of the roller 31 after positioning, and fixing the position of the supporting and storing fence 1. Further, the lifting and supporting wheel structure further comprises a deflection limiting structure. It can be understood that the horizontal rotation of the universal wheel also needs to be limited during positioning. The locking piece 33 is sleeved on the shaft of the universal wheel through a guide sleeve 38, the lower end of the supporting oil cylinder 30 is provided with an upper friction piece 39, and the upper end surface of the guide sleeve 38 is provided with a lower friction piece 40. During positioning, the upper friction piece 39 is in contact with the lower friction piece 40, and the friction force between the two friction pieces is converted from the gravity, thereby limiting the horizontal rotation of the universal wheel. It can be understood that the locking of the insertion rod 36 for the roller 31 and the directional locking of the friction piece are both automatic locking after the positioning of the supporting and storing fence 1. When the supporting and storing fence 1 is lifted by a forklift and needs to be assisted by the lifting and supporting wheel structure, the roller 31 is extended, so that the locking piece 33 is pushed up under the action of the jacking spring 37, thereby enabling the roller 31 to rotate freely, achieving the purpose of assisting in supporting and moving.
