Description

Technical Field

[0001] This invention relates to the field of stacker crane technology, specifically to a material stacker crane for construction production. Background Technology

[0002] A stacker crane is a specialized piece of equipment used in automated warehousing systems for storing and retrieving goods. It is mainly used in high-rise warehouses such as automated storage and retrieval systems (AS / RS) to achieve efficient and precise stacking and handling of goods.

[0003] Patent CN220300333U discloses a stacker crane, including: a column, a guide rail, and a loading platform. The guide rail is mounted on the column; a slider is provided on the loading platform, and the loading platform can slide on the guide rail through the cooperation of the slider. The stacker crane provided in this application guides the loading platform during lifting and lowering by the cooperation of the guide rail and the slider, preventing the loading platform from moving in directions other than the guide rail direction. This makes the entire operation easier to control, enhances the stability of the stacker crane, and saves the energy consumed in overcoming loading platform vibration. It also enables the stacker crane to smoothly and accurately lift and lower the loading platform to the required operating height.

[0004] However, the above-mentioned devices are difficult to fix the materials during operation, which may lead to problems such as material shaking and falling. At the same time, it is also difficult to buffer the materials when taking out the stacked materials, which may cause the impact of the materials hitting the bottom to damage brittle materials. Therefore, a material stacker for construction production is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a material stacker for construction production, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a material stacker for construction production, comprising a device foundation, a main frame fixedly connected to the top of the device foundation, a guide rail fixedly connected to the top of the device foundation, a feeding mechanism provided on the top of the guide rail, a rack structure fixedly connected to the top of the device foundation, the rack structure being located inside the main frame, an arrangement mechanism being provided inside the rack structure, and the feeding mechanism comprising: a set of traveling wheels, a lifting frame, a material receiving tray, an electric telescopic rod, a mounting base, a screw, a clamping plate, a damping rod, a support plate, and a vertical track. The traveling wheels are slidably connected to the top of the guide rail, the vertical track is fixedly connected to the top of the traveling wheels, the lifting frame is slidably connected to the surface of the vertical track, the electric telescopic rod is fixedly connected to the inner wall of the lifting frame, the material receiving tray is slidably connected to the surface of the lifting frame, the mounting base is fixedly connected to the front of the vertical track, the clamping plate is slidably connected to the surface of the mounting base, and the screw is rotatably connected to the front of the mounting base. Driven by a motor, the damping rod is fixedly connected to the top of the walking wheel assembly, the support plate is fixedly connected to the top of the damping rod, the bottom of the material receiving tray is fixedly connected to the extended end of the electric telescopic rod, and the screw is threadedly connected to the inner wall of the clamping plate. When the lifting frame is in its initial position, it contacts the support plate. The lifting frame is driven up and down by the internal drive wheel. When the device is running, the material is placed on the surface of the material receiving tray. The drive wheel on the inner wall of the lifting frame starts to move the lifting frame upward, and the upward movement of the lifting frame carries the material into the designated shelf. During the upward movement of the lifting frame, the material will contact the clamping plate. At this time, the screw is driven by the motor inside the mounting base to start rotating. The rotation of the screw drives the clamping plate to clamp the material through the thread, fixing the material and improving the stability during transportation. This prevents the material from falling due to shaking during transportation. When the material is removed, the lifting frame descends to the bottom and is squeezed. At this time, the lifting frame will contact and compress the damping rod. The compression of the damping rod serves to buffer the impact and avoid the shaking caused by the lifting frame hitting the bottom, effectively preventing damage to brittle materials.

[0007] Preferably, the shelving structure includes: shelving uprights, supporting beams, a fixed plate, a connecting frame, and a baffle. The shelving uprights are fixedly connected to the top of the device foundation, the supporting beams are fixedly connected to the surface of the shelving uprights, the fixed plate is fixedly connected between two horizontal shelving uprights, the connecting frame is slidably connected to the surface of the fixed plate, and the baffle is fixedly connected to the left side of the connecting frame. The shelving structure also includes: a push plate, a sliding rod, an elastic element, a corrugated plate, a servo motor, and a gear. The push plate is slidably connected to the surface of the fixed plate, the sliding rod is fixedly connected to the right side of the connecting frame, the elastic element is fixedly connected between the push plate and the fixed plate, the corrugated plate is fixedly connected to the side of the push plate near the sliding rod, the servo motor is fixedly connected to the bottom of the fixed plate, the gear is fixedly connected to the output end of the servo motor, and a rack is provided at the bottom of the fixed plate. The gear meshes with the rack at the bottom of the fixed plate. When the material on the receiving plate is lifted to the height of the receiving beam, the electric telescopic rod extends and pushes the receiving plate forward. The forward movement of the receiving plate moves the material forward, and the material contacts and pushes the baffle. The baffle moves with the material, offsetting the inertia and vibration during movement, preventing the material from tilting or sliding and causing it to tip over, thus avoiding damage to the goods. During the movement of the baffle, the connecting frame also moves, which in turn pushes the sliding rod to move. As the sliding rod contacts the corrugated plate, it moves with the sliding rod, and the corrugated plate is pushed to reciprocate in conjunction with the elastic element. The reciprocating movement of the corrugated plate drives the push plate to reciprocate. The reciprocating movement of the push plate continuously pushes and straightens the misaligned material, reducing positioning errors and preventing the subsequent inaccurate extraction due to the goods being skewed, thereby improving the operational reliability of the automated system.

[0008] Preferably, the arrangement mechanism includes: a slider, a roller, an insert plate, a connecting buckle, a stop block, and an electric push rod. The slider is slidably connected to the inner wall of the material-bearing crossbeam, the roller is rotatably connected to the inner wall of the slider, the electric push rod is fixedly connected to the bottom of the material-bearing crossbeam, the connecting buckle is fixedly connected to the bottom of the material-bearing crossbeam, the insert plate is slidably connected to the inner wall of the connecting buckle, and the stop block is fixedly connected to the side of the insert plate away from the slider. The extended end of the electric push rod contacts the stop block, the insert plate contacts the slider, and the stop block is located on the movement trajectory of the material-bearing tray. During the forward movement of the material-bearing tray loaded with material, the forward movement of the material-bearing tray will also contact and push the stop block. The movement of the stop block drives the insertion plate to move. During the movement of the insertion plate, it contacts and lifts the slider. The slider is pushed out by the insertion plate, which in turn pushes out the roller. When there is already material on the same load-bearing beam, the new material pushes the existing material forward to contact the roller and slide on the roller, reducing the sliding friction between the material and the load-bearing beam. This allows for easy pushing of heavy objects, reduces the working pressure of the electric telescopic rod, and extends the life of the device. After the material transfer is completed, the load-bearing tray retracts and returns to its initial position as the lifting frame resets. The electric push rod is then activated to push the stop block to reset. As the stop block and insertion plate move back, the material re-contacts the load-bearing beam, ensuring material stability and preventing accidental slippage of goods.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This material stacker for construction production uses the cooperation of the following components: walking wheel set, lifting frame, material receiving plate, electric telescopic rod, mounting base, screw, clamping plate, damping rod, support plate, and vertical track to fix materials, improve stability during transportation, prevent material from falling due to shaking during transportation, and use the damping rod compression to buffer the impact and shake caused by the lifting frame hitting the bottom, effectively preventing damage to brittle materials.

[0010] 2. This material stacker crane for construction production utilizes the interplay of components such as rack uprights, supporting beams, fixed plates, connecting frames, push plates, sliding rods, elastic elements, corrugated plates, baffles, servo motors, and gears. This allows the baffles to move with the materials, offsetting inertia and vibration during movement, preventing material slippage and tipping, and avoiding damage to goods caused by tilting. The reciprocating movement of the push plates continuously pushes and straightens misaligned materials, reducing positioning errors and preventing inaccurate subsequent retrieval due to skewed goods, thus improving the reliability of the automated system.

[0011] 3. This material stacker for construction production reduces the sliding friction between materials and the supporting beam through the cooperation of sliders, rollers, insert plates, connecting buckles, stops, and electric push rods. This allows for easy pushing of heavy objects, reduces the working pressure on the electric telescopic rod, and extends the life of the device. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-11One embodiment of the present invention is: a material stacker for construction production, comprising a device foundation 1, a main frame 2 fixedly connected to the top of the device foundation 1, a guide rail 3 fixedly connected to the top of the device foundation 1, a feeding mechanism 4 provided on the top of the guide rail 3, a rack structure 6 fixedly connected to the top of the device foundation 1, the rack structure 6 being located inside the main frame 2, and an arrangement mechanism 7 provided inside the rack structure 6. The feeding mechanism 4 includes: a set of traveling wheels 401, a lifting frame 402, a material receiving tray 403, an electric telescopic rod 404, a mounting base 405, a screw 406, a clamping plate 407, a damping rod 408, a support plate 409, and a vertical rail 5. The traveling wheels 401 are slidably connected to the top of the guide rail 3, the vertical rail 5 is fixedly connected to the top of the traveling wheels 401, the lifting frame 402 is slidably connected to the surface of the vertical rail 5, the electric telescopic rod 404 is fixedly connected to the inner wall of the lifting frame 402, and the material receiving tray 403 is slidably connected to the lifting frame. On the surface of 402, mounting base 405 is fixedly connected to the front of vertical track 5, clamping plate 407 is slidably connected to the surface of mounting base 405, screw 406 is rotatably connected to the front of mounting base 405, screw 406 is driven by an internal motor of mounting base 405, damping rod 408 is fixedly connected to the top of walking wheel set 401, support plate 409 is fixedly connected to the top of damping rod 408, bottom of material receiving plate 403 is fixedly connected to the extended end of electric telescopic rod 404, screw 406 is threaded to the inner wall of clamping plate 407, when lifting frame 402 is in the initial position it contacts support plate 409, lifting frame 402 is driven by internal drive wheel to move up and down, which can fix the material, improve the stability during transportation, prevent the material from falling due to shaking during transportation, and the damping rod 408 compression plays a buffering role to avoid the impact shaking caused by lifting frame 402 hitting the bottom, effectively preventing damage to brittle materials.

[0016] Working principle: When the device is running, the material is placed on the surface of the receiving tray 403. The drive wheel on the inner wall of the lifting frame 402 starts and moves the lifting frame 402 upward. The upward movement of the lifting frame 402 carries the material into the designated shelf. During the upward movement of the lifting frame 402, the material will contact the clamping plate 407. At this time, the screw 406 is driven by the motor inside the mounting base 405 to start rotating. The rotation of the screw 406 drives the clamping plate 407 to clamp the material through the thread, fixing the material and improving the stability during transportation. This prevents the material from falling due to shaking during transportation. When the material is removed, the lifting frame 402 descends to the bottom and is squeezed. At this time, the lifting frame 402 will contact and compress the damping rod 408. The compression of the damping rod 408 serves as a buffer to avoid the impact and shaking of the lifting frame 402 due to hitting the bottom, effectively preventing damage to brittle materials.

[0017] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, the shelf structure 6 includes: shelf uprights 601, material-bearing beams 602, fixing plates 603, connecting frames 604, and baffles 609. The shelf uprights 601 are fixedly connected to the top of the device foundation 1, the material-bearing beams 602 are fixedly connected to the surface of the shelf uprights 601, the fixing plates 603 are fixedly connected between two horizontal shelf uprights 601, the connecting frames 604 are slidably connected to the surface of the fixing plates 603, and the baffles 609 are fixedly connected to the left side of the connecting frames 604. The shelf structure 6 also includes: push plates 605, slide rods 606, elastic elements 607, corrugated plates 608, servo motors 610, and gears 611. The push plates 605 are slidably connected to the surface of the fixing plates 603, and the slide rods 606 are fixedly connected to the right side of the connecting frames 604. The elastic element 607 is fixedly connected between the push plate 605 and the fixed plate 603. The corrugated plate 608 is fixedly connected to the side of the push plate 605 near the slide rod 606. The servo motor 610 is fixedly connected to the bottom of the fixed plate 603. The gear 611 is fixedly connected to the output end of the servo motor 610. A rack is provided at the bottom of the fixed plate 603. The gear 611 meshes with the rack at the bottom of the fixed plate 603, which can make the baffle 609 move with the material. The baffle 609 moves with the material, offsetting the inertia and vibration during movement, preventing the material from tilting or sliding and causing it to tip over, thus avoiding damage to the goods caused by tipping. The push plate 605 reciprocates to continuously push and straighten the offset material, reducing positioning errors and preventing the subsequent inaccurate extraction due to the skewed goods, thereby improving the operational reliability of the automation system.

[0018] The arrangement mechanism 7 includes: a slider 701, a roller 702, an insert plate 703, a connecting buckle 704, a stop block 705, and an electric push rod 706. The slider 701 is slidably connected to the inner wall of the material-bearing crossbeam 602, the roller 702 is rotatably connected to the inner wall of the slider 701, the electric push rod 706 is fixedly connected to the bottom of the material-bearing crossbeam 602, the connecting buckle 704 is fixedly connected to the bottom of the material-bearing crossbeam 602, the insert plate 703 is slidably connected to the inner wall of the connecting buckle 704, and the stop block 705 is fixedly connected to the side of the insert plate 703 away from the slider 701. The extended end of the electric push rod 706 contacts the stop block 705, the insert plate 703 contacts the slider 701, and the stop block 705 is located on the movement trajectory of the material-bearing plate 403. This can reduce the sliding friction between the material and the material-bearing crossbeam 602, easily push heavy objects, reduce the working pressure of the electric telescopic rod 404, and extend the service life of the device.

[0019] Working principle: When the material receiving tray 403 lifts the loaded material to the height of the material receiving beam 602, the electric telescopic rod 404 extends and pushes the material receiving tray 403 forward. The forward movement of the material receiving tray 403 drives the material forward. The material moves forward and contacts and pushes the baffle 609. The baffle 609 moves with the material, offsetting the inertia and vibration during movement, preventing the material from tilting or sliding and causing it to tip over, thus avoiding damage to the goods caused by tipping. During the movement of the baffle 609, it also drives the connecting frame 604 to move. The movement of the connecting frame 604 pushes the sliding rod 606 to move. Since the sliding rod 606 contacts the corrugated plate 608, as the sliding rod 606 moves, the corrugated plate 608 is pushed and moves back and forth in conjunction with the elastic element 607. The back and forth movement of the corrugated plate 608 drives the push plate 605 to move back and forth. The back and forth movement of the push plate 605 continuously pushes and straightens the misaligned material, reducing positioning errors and avoiding the inability to accurately pick up the goods due to skewed goods, thus improving the operational reliability of the automation system.

[0020] During the forward movement of the material receiving tray 403, the forward movement of the material receiving tray 403 will also contact and push the stop block 705 to move. The movement of the stop block 705 will drive the insertion plate 703 to move. During the movement of the insertion plate 703, it will contact and lift the slider 701. The slider 701 will be pushed out by the insertion plate 703, which will also push the roller 702 out. When there is already material in the same grid of the material receiving beam 602, the new material will push the existing material forward to contact the roller 702 and slide on the roller 702, reducing the sliding friction between the material and the material receiving beam 602. This will make it easier to push heavy objects, reduce the working pressure of the electric telescopic rod 404, and improve the service life of the device. After the material transfer is completed, the material receiving tray 403 will retract and return to the initial position as the lifting frame 402 resets. The electric push rod 706 will start to push the stop block 705 to reset. As the stop block 705 and the insertion plate 703 move back, the material will contact the material receiving beam 602 again to ensure the stability of the material and prevent the goods from sliding accidentally.

[0021] This invention provides a material stacker for construction production. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
