Abstract
Description
Technical Field
[0001] This invention relates to the technical field of warehousing. More specifically, this invention relates to a pallet stacker with detection capabilities. Background Technology
[0002] When performing cargo handling operations on existing large pallet stacker cranes, a set of extendable, movable support blocks is typically used to support the pallet and the goods above it, and push them to the designated location on the rack. However, as the support block extends outward to deliver the pallet and goods into the rack, the end closest to the rack is often suspended in the air, lacking effective support. This structural design results in uneven stress on the support block when bearing heavy loads, causing large bending moments and deflections at the front end. This not only affects positioning accuracy but also significantly reduces the stability and safety of the overall structure. Long-term operation may also lead to mechanical fatigue or even failure. Summary of the Invention
[0003] In order to overcome the disadvantage that the end of the pallet near the shelf is often suspended in the air and the structure is unstable when the receiving block extends outward to send the pallet and goods into the shelf, the present invention provides a pallet stacker with detection function.
[0004] The technical solution of the present invention is: a pallet stacker with detection function, comprising a first track frame, a second track frame, and a trolley connecting the first track frame and the second track frame; the second track frame is arranged above the first track frame; it also includes a receiving platform, a first guide rail block, a first slider, a pallet, a second guide rail block, a second slider, a U-shaped frame, a first electric winding wheel, a first rope, and a drive assembly; the receiving platform is slidably connected to the trolley; the first guide rail block is fixedly connected to the receiving platform; the first slider is slidably connected to the first guide rail block; a chain driver is arranged between the first guide rail block and the first slider; a pallet is clamped on the first slider; a plurality of second guide rail blocks are fixedly connected to the receiving platform. Each guide rail block 2 is slidably connected to a slider 2; several U-shaped frames are fixedly connected to the receiving platform; several electric winding wheels 1 are fixedly connected to each U-shaped frame; each electric winding wheel 1 is connected to a rope 1, and the rope 1 is fixedly connected to the corresponding slider 2; a drive assembly is connected to the trolley; the drive assembly is used to drive the receiving platform to move up and down; several protrusions 1 are provided on the slider 1; several grooves 1 are provided on the support plate, and the grooves 1 cooperate with the corresponding protrusions 1; several protrusions 2 are provided on each slider 2; several grooves 2 are provided on the support plate, and the grooves 2 cooperate with the corresponding protrusions 2.
[0005] Furthermore, the drive assembly includes an electric winding reel 2, a rope 2, and a steering wheel; several electric winding reels 2 are fixedly connected to the trolley; each electric winding reel 2 is fixedly connected to a rope 2; several steering wheels are fixedly connected to the trolley; each rope 2 passes around the corresponding steering wheel and is fixedly connected to the receiving platform.
[0006] Furthermore, the pallet has several beveled sections.
[0007] Furthermore, it also includes a reinforcement component, which includes an electric push rod 1 and a fixing block; several electric push rods 1 are fixedly connected to each slider 2; several fixing blocks are provided above each slider 2, and the fixing blocks are fixedly connected to the corresponding electric push rods 1; several grooves 3 are provided on the support plate, and the grooves 3 cooperate with the corresponding fixing blocks.
[0008] Furthermore, it also includes limit blocks; several limit blocks are fixedly attached above each slider, and the limit blocks are slidably connected to the corresponding fixed blocks.
[0009] Furthermore, it also includes auxiliary components, which include a DD motor, an electric push rod II, and a limit block II; several DD motors are fixedly mounted on the receiving platform; an electric push rod II is fixedly mounted on the moving part of each DD motor; and a limit block II is fixedly mounted on the telescopic end of each electric push rod II.
[0010] Furthermore, the ends of the fixing block are chamfered.
[0011] Furthermore, the contact surfaces of both guide rail block two and slider two are set to be smooth surfaces.
[0012] Furthermore, a camera is installed on the receiving platform.
[0013] Furthermore, a brake is installed on the receiving platform.
[0014] The beneficial effects are: First, by using slider two and rope one together, a pulling force is provided to the extended end of the pallet, thereby reducing the pressure of the pallet and the goods on the end of slider one and avoiding the problem of insufficient structural stability and safety caused by the end of slider one being suspended. At the same time, slider two is also used to limit the two sides of the pallet placed on slider one, preventing the pallet from shifting during movement and further improving stability.
[0015] 2. When the chain drive on the guide rail block 1 fails, the electric reel 1 and rope 1, which provide tension to the extended end of the pallet, are also used to move the pallet and goods to the top of the receiving platform. Then, the electric reel 2 controls the receiving platform and its components to descend to the ground for maintenance operations, thus avoiding the maintenance difficulties caused by the pallet being stuck at a high altitude and unable to move down.
[0016] Third, the end of the fixing block is inserted into the groove three, thereby locking the tray onto the slider two, avoiding the tray from shifting or shaking, and improving stability;
[0017] Fourth, by using limit block two to push the pallet to the inside of the receiving platform, the problem of insufficient horizontal pushing force caused by the tension direction of rope one tending to be vertical in the later stage of winding, which makes it difficult to completely retract the pallet to the inside of the receiving platform, is avoided. At the same time, limit block two, which is used to assist rope one in pushing the pallet to the inside of the receiving platform, is also used to limit the two ends of the pallet to improve the stability of the cargo transportation process.

Detailed Implementation
[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0028] Example 1: A pallet stacker with detection function, such as Figures 1-8As shown, it includes a track frame 1, a track frame 2, and a trolley 3; the track frame 2 is mounted above the track frame 1; the trolley 3 connects the track frame 1 and the track frame 2; it also includes a receiving platform 4, a guide rail block 5, a slider 6, a support plate 7, a guide rail block 8, a slider 9, a U-shaped frame 10, an electric winding wheel 11, a rope 12, and a drive assembly; the receiving platform 4 is slidably connected to the trolley 3, and the receiving platform 4 is made of alloy material; the guide rail block 5 is bolted to the receiving platform 4; the slider 6 is slidably connected to the guide rail block 5, and the slider 6 is made of alloy material; a chain drive is provided between the guide rail block 5 and the slider 6; the support plate 7 is clamped on the slider 6; the receiving platform 4 is bolted... Two guide rail blocks 28 are connected; each guide rail block 28 has a slider 29 slidably connected to it; two U-shaped frames 10 are bolted to the receiving platform 4; each U-shaped frame 10 has two electric winding wheels 11 bolted to it; each electric winding wheel 11 has a rope 12 connected to it, and the rope 12 is fixed to the corresponding slider 29; a drive assembly is connected to the traveling trolley 3; two protrusions 91 are provided on the slider 16; two grooves 92 are provided on the support plate 7, and the grooves 92 cooperate with the corresponding protrusions 91; two protrusions 93 are provided on each slider 29; four grooves 94 are provided on the support plate 7, and the grooves 94 cooperate with the corresponding protrusions 93.
[0029] The drive assembly includes an electric winding reel 201, a rope 202, and a steering wheel 203. Two electric winding reels 201 are bolted to the traveling trolley 3. A rope 202 is fixed to each electric winding reel 201. Two steering wheels 203 are bolted to the traveling trolley 3. Each rope 202 passes around the corresponding steering wheel 203 and is fixed to the receiving platform 4. The electric winding reel 201 winds up the rope 202. Under the steering action of the steering wheel 203, the rope 202 drives the receiving platform 4 to move upward.
[0030] The pallet 7 has several inclined surfaces 95. When the pallet 7 is transferred to the top of the guide block 5 by the external conveying device, the inclined surfaces 95 guide the pallet 7 so that the pallet 7 can be smoothly engaged on the outside of the slider 6.
[0031] First, the equipment is installed in the gap between adjacent shelves. An external conveyor places the pallet 7, carrying goods, onto slider 6 and slider 9, with protrusion 91 engaging with groove 92 and protrusion 93 engaging with groove 94. Then, the traveling crane 3 moves along track 1 and track 2, causing the pallet 7 and goods to move horizontally. Electric winding wheel 201 winds up rope 202. Under the steering action of steering wheel 203, rope 202 drives the receiving platform 4 upwards, thus moving the pallet 7 and goods vertically. As the slider moves to the side of the shelf to be placed, the chain driver on guide block 5 drives slider 6 to move towards the shelf. Slider 6 moves pallet 7 to the shelf to be placed. During this process, pallet 7 moves slider 9 on guide block 8, and slider 9 moves the end of rope 12. Electric winding wheel 11 is activated, and it adaptively unwinds rope 12 to keep it taut. After slider 9 extends towards the shelf, the end of slider 9 away from the shelf is supported by guide block 8, and the end of slider 9 near the shelf is tightened by rope 12, thus making slider 9... The even force applied to both ends supports the pallet 7 and the goods, reducing the pressure of the goods on the end of the slider 6. This avoids the structural instability and safety issues caused by the end of the slider 6 being suspended. Simultaneously, the second slider 9 also limits the sides of the pallet 7 placed on the slider 6, preventing the pallet 7 from shifting during movement and further improving stability. Then, the electric rewind wheel 11 controls the receiving platform 4 and its components to move downwards, allowing the pallet 7 to rest on the shelf. The electric rewind wheel 11 continues to control the receiving platform 4 and its components to move downwards, causing the protrusion 91 to move away from the groove 92. The second slide 93 moves away from the groove 94, and then the chain driver on the guide block 5 drives the slider 6 to move back to its original position. The electric winding wheel 11 drives the slider 9 to move back to its original position, thus placing the pallet 7 and the goods together on the shelf. During operation, the slider 9 cooperates with the rope 12 to provide tension for the extended pallet 7, thereby significantly reducing the pressure of the goods on the suspended end of the slider 6. This effectively solves the problem of insufficient structural stability and safety caused by the suspended end. At the same time, the slider 9 also limits the sides of the pallet 7 to prevent it from shifting during movement, further improving the operational stability.
[0032] If the chain drive on the guide block 5 malfunctions during the movement of the slider 6, pallet 7, and goods towards the shelf, the pallet 7 and goods cannot be placed on the shelf, and the end of the pallet 7 has already moved to the inside of the shelf. At this time, the electric rewind wheel 201 cannot drive the receiving platform 4 and its parts down to the ground, requiring manual climbing to the high-altitude receiving platform 4 for maintenance, significantly increasing the difficulty of maintenance. In this design, the guide block 28, slider 29, electric rewind wheel 11, and rope 12, which provide tension, also have an emergency retrieval function. When the chain drive on the guide block 5 malfunctions, the electric rewind wheel 11 can be activated to rewind the rope 12, driving the slider 7 to move towards the shelf. Block 29 slides on guide rail block 28, causing slider 29 to move pallet 7 and goods to above receiving platform 4. Then, electric winding wheel 201 controls the receiving platform 4 and its parts to descend to the ground. At this point, manual maintenance can be performed, reducing maintenance difficulty. In use, if the chain drive on guide rail block 15 malfunctions, electric winding wheel 111 and rope 12, which provide tension to the extended end of pallet 7, are also used to move pallet 7 and goods to above receiving platform 4. Subsequently, electric winding wheel 201 controls the receiving platform 4 and its parts to descend to the ground for maintenance, avoiding the maintenance difficulties caused by pallet 7 being stuck at a height and unable to descend.
[0033] It also includes a reinforcement component, which includes an electric push rod 204 and a fixing block 205; four electric push rods 204 are fixedly connected to each slider 29; two fixing blocks 205 are provided above each slider 29, and the fixing blocks 205 are fixedly connected to the corresponding electric push rods 204; four grooves 396 are provided on the support plate 7.
[0034] It also includes a limit block 206; each slider 29 has two limit blocks 206 bolted to its top, and the limit blocks 206 are slidably connected to the corresponding fixing blocks 205. By providing support force to the fixing blocks 205 through the limit blocks 206, the fixing blocks 205 can lock the support plate 7 more stably.
[0035] When the pallet 7 and the goods are moved into the receiving platform 4 by the rope 12, the control precision of the rope 12 on the pallet 7 is low, and it is easy for the pallet 7 to wobble and deviate. Therefore, before the pallet 7 and the goods are moved by the rope 12, the electric push rod 204 is activated. The electric push rod 204 drives the fixing block 205 to move within the limiting block 206 and inserts the end of the fixing block 205 into the groove 96, thereby locking the pallet 7 onto the slider 9, avoiding the problem of the pallet 7 deviating and wobbling, and improving stability.
[0036] It also includes auxiliary components, including a DD motor 207, an electric push rod 208, and a limit block 209; four DD motors 207 are fixedly connected to the receiving platform 4; an electric push rod 208 is fixedly connected to the movable part of each DD motor 207; a limit block 209 is fixedly connected to the telescopic end of each electric push rod 208, and the limit block 209 is moved horizontally by the electric push rod 208.
[0037] When the pallet 7 is pulled back to the receiving platform 4 by rope 12, as the pallet 7 continues to retract, the angle between rope 12 and the horizontal plane gradually increases, and the horizontal component of its tension decreases accordingly. When the pallet 7 is almost fully retracted, rope 12 is nearly vertical, and the horizontal component of the tension is very weak, which may prevent the pallet 7 from fully returning to the inside of the receiving platform 4, thus interfering with subsequent descent operations. Therefore, an auxiliary component is installed on the receiving platform 4. When rope 12 can no longer move the pallet 7, electric push rod 208 drives limit block 209 to move to the lower front of the pallet 7, and then... The DD motor 207 drives the electric push rod 208 and the limit block 209 to rotate, causing the limit block 209 to move to the front of the pallet 7. Then, the electric push rod 208 drives the limit block 209 to move towards the receiving platform 4, causing the limit block 209 to push the pallet 7 to the inside of the receiving platform 4. After that, the receiving platform 4 and the parts on it are moved to the ground for maintenance operations, avoiding interference problems. In use, the limit block 209 pushes the pallet 7 to the inside of the receiving platform 4, avoiding the problem that it is difficult to push the pallet 7 to the inside of the receiving platform 4 completely when the rope 12 gradually turns into a vertical state.
[0038] After the second limiting block 209 pushes the pallet 7 to the inside of the receiving platform 4, the second limiting block 209 remains in contact with the pallet 7. At this time, the two ends of the pallet 7 are limited by the second limiting block 209 to prevent it from sliding and deviating due to vibration, thereby further improving stability. In addition, the pallet 7 can also be limited by the second limiting block 209 during normal operation to improve the stability of the cargo transportation process.
[0039] Example 2, based on Example 1, such as Figure 6 As shown, the end of the fixing block 205 is chamfered, making it easier for the fixing block 205 to be inserted into the groove 3 96.
[0040] The contact surfaces of guide block 28 and slider 29 are both set to be smooth surfaces to reduce friction.
[0041] A camera is installed on receiving platform 4 to detect the status of the goods. When an abnormality is detected in the position of the goods, the camera will alert staff to go for maintenance.
[0042] A brake is installed on the receiving platform 4. When the receiving platform 4 slides down rapidly, the brake is used to stop the receiving platform 4, which helps to improve safety.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
