Description

Technical Field

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

[0002] A construction material stacker is a mechanical device used on construction sites to stack and transport building materials. It improves the efficiency of material stacking by stacking and unloading goods, so as to facilitate subsequent transportation and retrieval.

[0003] Patent publication number CN220975418U relates to the field of stacker crane technology, specifically an automated warehouse stacker crane, comprising a body and a housing. The upper end of the body is equipped with a lifting mechanism, which includes a motor. The outer wall of the motor is fixedly connected to the body via a bracket. The outer wall of the first threaded rod is threadedly connected to the lifting plate. Through the cooperation of the body and the lifting mechanism, the motor drives the first bevel gear to rotate. After the lifting plate moves to a suitable height, the motor stops working, and the materials are stacked. This method avoids damage to the traction rope, reducing the maintenance cost of the stacker crane. Through the cooperation of the lifting plate and the clamping mechanism, the first electric telescopic rod drives the second threaded rod to move, and the second threaded rod drives the gear to rotate, clamping the materials with a soft pad. This method ensures that the clamping plate can always hold the materials firmly, preventing them from shaking or falling, thus reducing the operational hazards of the stacker crane.

[0004] In the aforementioned patent, through the cooperation of the lifting plate and the clamping mechanism, the first electric telescopic rod drives the second threaded rod to move, and the second threaded rod drives the gear to rotate. The soft pad clamps the material. In this way, the clamping plate can always clamp the material and prevent it from shaking and falling, thus reducing the working danger of the stacker crane. However, during use, if the material is conveyed too fast, it may cause the material to accumulate and affect normal use. At the same time, the material belt may be misaligned during the conveying process, which may result in uneven material stacking and affect the stability of the material stack.

When the long rod moves upward, it will push the short rod to rotate upward. When the short rod rotates upward, it will push the rotating rod to rotate upward. When the rotating rod rotates upward, it will drive the pulley connecting seat to rotate downward.

[0008] According to the above technical solution, a reset torsion spring is provided between the square frame and the rotating rod. The reset torsion spring drives the rotating rod to reset. The short plate is in contact with the surface of the fixed plate. A first spring is provided between the fixed frame and the trapezoidal slide plate.

[0009] According to the above technical solution, the fixed frame is provided with a placement device and a correction device for assisting placement. The placement device includes a pulley frame, a sliding plate, a clamping plate, and a trapezoidal plate. The pulley frame moves away from the drive motor by moving the placement plate away from the drive motor. The pulley frame will contact the trapezoidal plate in the direction away from the drive motor. The pulley frame is fixedly installed on the surface of the placement plate. The sliding plate is slidably installed on the inner wall of the fixed frame. The sliding plate is fixedly installed on the top of the drive motor.

Subsequently, the plate reset will drive the pulley frame to reset, and the pulley frame reset will push the long plate, the connecting plate, and the trapezoidal slider to move away from the fixing block. The movement of the trapezoidal slider away from the fixing block will release the limitation on the fixing block, so that the No. 3 spring will drive the clamping plate to reset.

[0012] According to the above technical solution, the correction device includes a rotating shaft, a correction plate, a rotating plate, and a pull rope. The rotating shaft, the correction plate, and the rotating plate move away from the fixed frame by moving the clamping plate away from the fixed frame. The rotating plate is pulled away from the fixed frame by the pull rope. The clamping plate has a groove on its surface. The rotating shaft is rotatably mounted on the inner wall of the groove. The correction plate is fixedly mounted on the circumferential surface of the rotating shaft. The rotating plate is fixedly mounted on the circumferential surface of the rotating shaft. One end of the pull rope is fixedly mounted on the inner wall of the fixed frame, and the other end of the pull rope is fixedly mounted on the surface of the rotating plate.

[0013] According to the above technical solution, a sliding rod slides through the surface of the clamping plate, a connecting frame is fixedly installed on the side of the clamping plate near the fixed frame, a rotating rod is rotatably installed on the surface of the connecting frame, a baffle is fixedly installed at the end of the rotating rod near the sliding rod, a push plate is fixedly installed at the bottom of the rotating rod, and a trapezoidal support plate is slidably installed at the bottom of the clamping plate. When the push plate rotates upward, it will push the trapezoidal support plate to move away from the fixed frame, thereby supporting the bottom of the material by moving the trapezoidal support plate away from the fixed frame.

[0014] According to the above technical solution, a first torsion spring is provided between the rotating shaft and the groove. The rotating shaft is reset by the elastic force of the first torsion spring. A second torsion spring is provided between the connecting frame and the rotating rod.

When the sliding rod is separated from the material, the elastic force of the fifth spring will reset the sliding rod. A sixth spring is provided between the clamping plate and the trapezoidal support plate. When the trapezoidal support plate is separated from the push plate, the elastic force of the sixth spring will reset the trapezoidal support plate.

[0015] This invention provides a material stacker for construction. It has the following advantages: (1) In this invention, the upward movement of the trapezoidal sliding plate will block the material on the conveying equipment, reasonably separate and guide the material, and avoid the accumulation or misalignment of the material. At the same time, the upward rotation of the short rod will push the rotating rod to rotate upward, and the upward rotation of the rotating rod will drive the pulley seat to rotate downward. The downward rotation of the pulley seat will hold the material down and prevent the material from sticking up on the conveying equipment, which will affect the material conveying effect. At the same time, the roller will contact the triangular plate during the upward movement. The triangular plate will push the roller and the pulley seat to move closer to the center of the placement plate. The movement of the pulley seat to move closer to the center of the placement plate will drive the clamping plate to move closer to the center of the placement plate. The movement of the clamping plate to move closer to the center of the placement plate will correct the material on the placement plate and prevent the material from shifting, which will affect the stacking effect.

[0016] (2) In this invention, the movement of the trapezoidal plate away from the sliding plate will cause the clamping plate to move away from the sliding plate. The material is clamped by the movement of the clamping plate away from the sliding plate, ensuring that the material is directly above the stacked material and that the position is neat. The fixed block is limited by the trapezoidal slider, so that the clamping plate always clamps the material. After being clamped by the clamping plate, the drive motor will drive the placement plate to reset. The placement plate moves towards the conveying equipment to disengage from the material. Then the reset of the placement plate will drive the pulley frame to reset. The reset of the pulley frame will push the long plate, connecting plate and trapezoidal slider to move away from the fixed block. The movement of the trapezoidal slider away from the fixed block will release the limitation on the fixed block, so that the No. 3 spring will drive the clamping plate to reset. The reset of the clamping plate will cause the material to fall onto the material pile. The equipment can realize automatic clamping and discharging, and the operation is more convenient.

[0017] (3) The invention corrects the position of the material by moving the straightening plate closer to the material, preventing the material from shifting from the material pile during stacking, which would result in an uneven stack and affect the stability of the material pile. At the same time, the upward rotation of the push plate will push the trapezoidal pallet to move away from the fixed frame. The movement of the trapezoidal pallet away from the fixed frame will support the bottom of the material, preventing the material from sliding down when the clamping plate is clamped, which would cause the material pile at the bottom to be misaligned, affecting the placement and transportation of the material pile and affecting the overall work efficiency.

[0020] 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.

[0021] Please see Figure 1 - Figure 7 One embodiment of the present invention is a material stacker for construction, comprising: a conveying device 1; a fixed frame 2, the fixed frame 2 being fixedly installed on the surface of the conveying device 1; a moving vehicle 3, the moving vehicle 3 being disposed below the fixed frame 2; a linear motor 4, the linear motor 4 being fixedly installed on the inner wall of the fixed frame 2; a drive motor 5, the drive motor 5 being fixedly installed at the output end of the linear motor 4, the linear motor 4 being used to drive the drive motor 5 to move up and down; and a placement plate 6, the placement plate 6 being fixedly installed at the output end of the drive motor 5, the drive motor 5 being used to drive the placement plate 6 to move laterally. A trapezoidal slide plate 7 is slidably mounted on the surface of the fixed frame 2. A short plate 9 is fixedly mounted on the surface of the trapezoidal slide plate 7. A clamping plate 11 is slidably mounted on the top of the drive motor 5. A fixed plate 8 is fixedly mounted on the side of the clamping plate 11 near the short plate 9. A triangular plate 10 is fixedly mounted on the inner wall of the fixed frame 2. A pulley seat 12 is fixedly mounted on the side of the clamping plate 11 near the triangular plate 10. A roller 13 is rotatably mounted on the inner wall of the pulley seat 12. When the trapezoidal slide plate 7 moves upward, it will block the material on the conveying equipment 1, reasonably separate and guide the material, and avoid the accumulation or misalignment of the material.

[0022] A square frame 131 is fixedly installed on the side of the fixed frame 2 near the conveying equipment 1. A rotating rod 132 is rotatably installed on the side of the square frame 131 near the middle of the conveying equipment 1. A pulley connecting seat 133 is fixedly installed on the circumference of the rotating rod 132. A short rod 134 is fixedly installed on the circumference of the rotating rod 132. A long rod 135 is fixedly installed on the side of the trapezoidal slide plate 7 near the linear motor 4. The material is pressed down by rotating the pulley connecting seat 133 downward to prevent the material from tilting on the conveying equipment 1 and affecting the material conveying effect.

[0023] A reset torsion spring is provided between the square frame 131 and the rotating rod 132. The reset torsion spring drives the rotating rod 132 to reset. The short plate 9 is in contact with the surface of the fixed plate 8. A first spring is provided between the fixed frame 2 and the trapezoidal slide plate 7. When the fixed plate 8 is separated from the short plate 9, the elastic force of the first spring will drive the trapezoidal slide plate 7 to reset. A second spring is provided between the drive motor 5 and the clamping plate 11. When the roller 13 is separated from the triangular plate 10, the elastic force of the second spring will drive the clamping plate 11 to reset.

[0024] In this embodiment, during operation: materials are conveyed via conveyor 1. When the materials reach the placement plate 6, the linear motor 4 moves upward, driving the drive motor 5 upward. The drive motor 5 moves upward, causing the placement plate 6 to move upward, positioning it above the stacked materials. As the placement plate 6 moves upward, the clamping plate 11 moves upward, which in turn moves the fixing plate 8 upward. The fixing plate 8 then disengages from the limiting position of the short plate 9. Subsequently, the elastic force of the first spring causes the trapezoidal sliding plate 7 to move upward. The upward movement of the trapezoidal sliding plate 7 blocks the materials on the conveyor 1, effectively separating and guiding them to prevent accumulation or misalignment. The upward movement of the trapezoidal sliding plate 7 also causes the long rod 135 to move upward, which in turn pushes the short rod. When the short rod 134 rotates upward, it pushes the rotating rod 132 to rotate upward. The upward rotation of the rotating rod 132 drives the pulley connecting seat 133 to rotate downward. The downward rotation of the pulley connecting seat 133 holds the material in place, preventing it from tilting on the conveying equipment 1 and affecting the conveying effect. At the same time, the upward movement of the clamping plate 11 drives the pulley seat 12 to move upward. The upward movement of the pulley seat 12 drives the roller 13 to move upward. During the upward movement of the roller 13, it will contact the triangular plate 10. The triangular plate 10 will push the roller 13 and the pulley seat 12 to move closer to the center of the placement plate 6. The movement of the pulley seat 12 closer to the center of the placement plate 6 will drive the clamping plate 11 to move closer to the center of the placement plate 6. The movement of the clamping plate 11 closer to the center of the placement plate 6 will correct the material on the placement plate 6 and prevent the material from shifting, which would affect the stacking effect.

[0025] Please see Figure 1 - Figure 7Based on the above embodiments, in another embodiment of the present invention, the fixed frame 2 is provided with a placement device and a correction device for assisting placement. The placement device includes a pulley frame 141, a sliding plate 142, a clamping plate 143 and a trapezoidal plate 144. The pulley frame 141 is fixedly installed on the surface of the placement plate 6, the sliding plate 142 is slidably installed on the inner wall of the fixed frame 2, the sliding plate 142 is fixedly installed on the top of the drive motor 5, the clamping plate 143 is slidably installed on the top of the sliding plate 142, and the trapezoidal plate 144 is fixedly installed on the bottom of the clamping plate 143. The material is clamped by moving the clamping plate 143 away from the sliding plate 142, ensuring that the material is directly above the stacked material and that the position is neatly arranged.

[0026] A fixing block 145 is fixedly installed on the surface of the clamping plate 143. A trapezoidal slider 146 is slidably installed on the top of the sliding plate 142. A connecting plate 147 is fixedly installed on the bottom of the trapezoidal slider 146. A long plate 148 is fixedly installed on the side of the connecting plate 147 near the pulley frame 141. When the clamping plate 143 is reset, the material will fall onto the material pile. The equipment can realize automatic clamping and feeding, making the operation more convenient.

[0027] A third spring is provided between the sliding plate 142 and the clamping plate 143. When the pulley frame 141 is disengaged from the trapezoidal plate 144, the elastic force of the third spring will cause the clamping plate 143 to return to its original position. A fourth spring is provided between the sliding plate 142 and the trapezoidal slider 146. When the pulley frame 141 is disengaged from the long plate 148, the elastic force of the fourth spring will cause the trapezoidal slider 146 to return to its original position.

[0028] The straightening device includes a rotating shaft 151, a straightening plate 152, a rotating plate 153, and a pull rope 154. The clamping plate 143 has a groove on its surface. The rotating shaft 151 is rotatably mounted on the inner wall of the groove. The straightening plate 152 is fixedly mounted on the circumferential surface of the rotating shaft 151. The rotating plate 153 is fixedly mounted on the circumferential surface of the rotating shaft 151. One end of the pull rope 154 is fixedly mounted on the inner wall of the fixing frame 2, and the other end of the pull rope 154 is fixedly mounted on the surface of the rotating plate 153. The position of the material is corrected by moving the straightening plate 152 towards the material, so as to prevent the material from shifting from the material pile during stacking, which would result in an uneven stack and affect the stability of the material pile.

[0029] A sliding rod 155 slides through the surface of the clamping plate 143. A connecting frame 156 is fixedly installed on the side of the clamping plate 143 near the fixed frame 2. A rotating rod 157 is rotatably installed on the surface of the connecting frame 156. A baffle 158 is fixedly installed at the end of the rotating rod 157 near the sliding rod 155. A push plate 159 is fixedly installed at the bottom of the rotating rod 157. A trapezoidal support plate 1510 is slidably installed at the bottom of the clamping plate 143 to prevent the material from sliding down when the clamping plate 143 is clamping, which would cause the material pile at the bottom to align, affecting the placement and transportation of the material pile and affecting the overall work efficiency.

[0030] A first torsion spring is installed between the rotating shaft 151 and the groove. The first torsion spring's own elastic force drives the rotating shaft 151 to reset. A second torsion spring is installed between the connecting frame 156 and the rotating rod 157. The second torsion spring's own elastic force drives the rotating rod 157 to reset. A fifth spring is installed between the clamping plate 143 and the sliding rod 155. When the sliding rod 155 is disengaged from the material, the fifth spring's own elastic force drives the sliding rod 155 to reset. A sixth spring is installed between the clamping plate 143 and the trapezoidal support plate 1510. When the trapezoidal support plate 1510 is disengaged from the push plate 159, the sixth spring's own elastic force drives the trapezoidal support plate 1510 to reset.

[0031] In this embodiment, during operation: the placement plate 6 moves away from the drive motor 5, causing the pulley frame 141 to move away from the drive motor 5. The pulley frame 141, moving away from the drive motor 5, contacts the trapezoidal plate 144, pushing the trapezoidal plate 144 away from the sliding plate 142. This movement of the trapezoidal plate 144 away from the sliding plate 142 causes the clamping plate 143 to move away from the sliding plate 142. The movement of the clamping plate 143 away from the sliding plate 142... The material is clamped to ensure it is directly above the stacked material and that it is neatly arranged. Simultaneously, as the pulley frame 141 moves away from the drive motor 5, it loses pressure on the long plate 148. The elastic force of the fourth spring causes the trapezoidal slider 146 to reset. The reset of the trapezoidal slider 146 causes the long plate 148 and connecting plate 147 to reset. At the same time, the clamping plate 143 moves away from the sliding plate 142, causing the fixing block 145 to move away from the sliding plate 142. The directional movement of plate 142 will contact the reset trapezoidal slider 146. The fixing block 145 will push the trapezoidal slider 146 to move away from the fixing block 145. When the fixing block 145 disengages from the trapezoidal slider 146, the elastic force of the fourth spring will drive the trapezoidal slider 146 to reset. The trapezoidal slider 146 limits the fixing block 145, ensuring that the clamping plate 143 always clamps the material. After being clamped by the clamping plate 143, the drive motor 5 will drive the placement plate 6 to reset, and the placement plate 6 will move the material closer to the conveyor. When device 1 moves away from the material support, the placement plate 6 resets, which in turn drives the pulley frame 141 to reset. The reset of the pulley frame 141 pushes the long plate 148, connecting plate 147, and trapezoidal slider 146 to move away from the fixed block 145. The movement of the trapezoidal slider 146 away from the fixed block 145 releases the limitation on the fixed block 145, causing the third spring to reset the clamping plate 143. The reset of the clamping plate 143 causes the material to fall onto the material pile. The equipment can automatically clamp and release materials, making operation more convenient.

[0032] The movement of the clamping plate 143 away from the fixed frame 2 causes the rotating shaft 151, the straightening plate 152, and the rotating plate 153 to move away from the fixed frame 2. The rotating plate 153, moving away from the fixed frame 2, is pulled by the pull rope 154, causing it to rotate. This rotation of the rotating plate 153 drives the rotating shaft 151 and the straightening plate 152 to rotate. The straightening plate 152 moves closer to the material to correct its position, preventing the material from shifting from the material pile during stacking, which would result in an uneven stack and affect the stability of the material pile. Simultaneously, the movement of the clamping plate 143 closer to the material causes the sliding rod 155 to move closer to the material. When the material moves in the direction of contact with the sliding rod 155, the reverse force will push the sliding rod 155 to move closer to the fixed frame 2. The movement of the sliding rod 155 closer to the fixed frame 2 will push the baffle 158 to rotate downward. The downward rotation of the baffle 158 will drive the rotating rod 157 and the push plate 159 to rotate upward. The upward rotation of the push plate 159 will push the trapezoidal support plate 1510 to move away from the fixed frame 2. The movement of the trapezoidal support plate 1510 away from the fixed frame 2 will support the bottom of the material and prevent the material from sliding down when clamped by the clamping plate 143. This would cause the material pile at the bottom to align, affecting the placement and transportation of the material pile and affecting the overall work efficiency.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
