Description

Technical Field

[0001] The utility model relates to the technical field of stacking cranes, in particular to a storage and stacking device for a stereoscopic warehouse. Background Art

[0002] Stacking crane, also known as stacker, is the most important lifting and transportation equipment in the three-dimensional warehouse and is a symbol of the characteristics of the three-dimensional warehouse. Its main function is to run back and forth in the aisles of the three-dimensional warehouse, store the goods at the entrance of the aisle into the cargo compartment of the shelf, or take out the goods in the cargo compartment and transport them to the entrance of the aisle.

[0003] However, when the existing three-dimensional warehouse storage and stacking equipment is in use, the goods to be stored are usually placed according to the load weight of the loading platform. When the load of the loading platform exceeds the specified load, since the loading platform only relies on lifting mechanisms such as slide rails to control the lifting, it is easy for the loading platform to suddenly fall due to overweight, resulting in a greater probability of the loading platform colliding with the bottom structure and being damaged. In addition, in order to maintain linear motion in the aisle, the existing stacking equipment is usually equipped with ground tracks so that the stacker can maintain a straight line when running in the aisle. The narrow and long ground tracks are set in narrow aisles, which makes it difficult for operators to enter the aisles for maintenance and maintenance, resulting in the ground rails being more troublesome and time-consuming to maintain.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4As shown in the figure, the three-dimensional warehouse storage stacking equipment of this embodiment includes a gantry 1. Rotating shafts 15 are provided on both sides of the gantry 1. A ratchet wheel 12 is sleeved at one end of the rotating shaft 15. Ratchet teeth 13 are provided on one side of the ratchet wheel 12. A winding drum 20 is sleeved in the middle of the rotating shaft 15. A steel cable 3 is movably wound around the middle of the winding drum 20. A clamping block 4 is fixedly connected to the bottom end of the steel cable 3. A loading platform 5 is provided on one side of the clamping block 4. A fork mechanism 6 is fixedly installed at the top end of the loading platform 5. A lifting mechanism 16 is installed inside the gantry 1. The bottom end of the gantry 1 is fixedly connected to a base 7. Side boxes 8 are clamped at both ends of the base 7. An oil storage cylinder 9 movably penetrates through the top end of one of the side boxes 8. A ball 18 is movably embedded at the oil outlet at the bottom end of the oil storage cylinder 9. A sleeve frame 10 is clamped in the middle of the side box 8. A brush piece 19 is fixedly connected to the inner wall of the sleeve frame 10. A ground rail 11 is installed at the bottom of the base 7. Lubricating oil 17 is filled inside the oil storage cylinder 9. A speed sensor 21 is installed on one side of the rotating shaft 15.

[0024] Specifically, the rotating shaft 15 can be driven by the steel cable 3 through the winding drum 20 to rotate, and the steel cable 3 can slide up and down under the traction of the lifting mechanism 16 through the clamping block 4 and the loading platform 5 to realize the pulling of the winding drum 20. After the ratchet teeth 13 and the ratchet wheel 12 are engaged, the ratchet wheel 12 can be stopped from rotating, thereby braking the rotating shaft 15 fixed to the ratchet wheel 12, making the winding drum 20 on the rotating shaft 15 stop rotating, and making the steel cable 3 in the winding drum 20 stop unfolding, so as to realize the traction braking of the steel cable 3 on the clamping block 4 and the loading platform 5, reducing the probability that the loading platform 5 suddenly drops to the bottom of the equipment and collides with the bottom of the equipment. The steel cable 3, as a traction braking mechanism, can perform secondary control on the lifting of the loading platform 5, so that the loading platform 5 is more stable during the lifting process. Sliders matching the ground rail 11 are installed inside the base 7, so that the base 7 can slide smoothly along the ground rail 11. The side box 8 can push and clean the sundries on the ground rail 11 to prevent the sundries from being卷入 the inside of the base 7, thus ensuring the smooth sliding of the base 7 on the ground rail 11. The oil storage cylinder 9 is inverted with the opening facing down at the top end of the side box 8. The surface of the ball 18 is smooth, and the outer diameter is adapted to the inner diameter of the opening of the oil storage cylinder 9, so that the ball 18 can roll smoothly in the opening of the oil storage cylinder 9, enabling the lubricating oil 17 in the oil storage cylinder 9 to be smeared on the ground rail 11 along the rolling ball 18 under the action of gravity, thereby realizing the lubrication and maintenance of the ground rail 11 and avoiding the need for operators to enter the narrow roadway for maintenance work. The cross-section of the sleeve frame 10 is in the shape of "冂", so that the sleeve frame 10 can slide along the surface of the ground rail 11, and thus the brush piece 19 on the inner wall of the sleeve frame 10 can wipe the ground rail 11 in contact, cleaning the dust on the ground rail 11, which is beneficial to the subsequent application of the lubricating oil 17.

[0025] Furthermore, both sides of the top of the gantry 1 are fixedly connected with a cover box 2, and the rotating shaft 15 is rotatably connected to the inside of the cover box 2. The rotating shaft 15 is rotatably connected to the gantry 1 through the cover box 2. The cover box 2 can protect part of the ground rails 11 on both sides of the base 7, thereby reducing the probability of debris being drawn into the base 7.

[0026] Furthermore, the ratchet 13 is movably connected to the gantry 1, and an electric push rod 14 is provided on one side of the ratchet 13. The electric push rod 14 is installed on the top of the inner side of the gantry 1, and the electric push rod 14 can push the ratchet 13 to approach the ratchet wheel 12, so that the ratchet wheel 12 can engage with the ratchet 13 in time, thereby realizing the braking of the steel cable 3 by the rotating shaft 15, so that the steel cable 3 performs traction braking on the block 4 and the cargo platform 5, thereby reducing the probability of the cargo platform 5 suddenly falling due to overweight.

[0027] Furthermore, the output end of the electric push rod 14 is movably connected to the ratchet 13, the ratchet 13 is meshed with the ratchet wheel 12 through the electric push rod 14, and the speed sensor 21 is electrically connected to the electric push rod 14. The speed sensor 21 can control the start of the electric push rod 14 through the single-chip microcomputer by measuring the speed of the rotating shaft 15, so that when the cargo platform 5 suddenly drops, the ratchet 13 can mesh with the ratchet wheel 12 in time.

[0028] Furthermore, the cargo platform 5 is installed on one side wall of the lifting mechanism 16, and the clamping block 4 is installed on the other side wall of the lifting mechanism 16. The clamping block 4 is engaged and connected with the cargo platform 5 through the lifting mechanism 16. The function of the clamping block 4 is to connect the steel cable 3 with the cargo platform 5, so that the speed of the cargo platform 5 sliding up and down is synchronized with the speed of the rotation of the rotating shaft 15 driven by the steel cable 3 after it is unfolded, thereby facilitating the speed sensor 21 to know the lifting and lowering speed of the cargo platform 5 by measuring the speed of the rotating shaft 15.

[0029] Furthermore, the ball 18 is slidably connected to the floor rail 11, and the brush piece 19 is movably connected to the floor rail 11 through the sleeve frame 10. Under the restriction of the sleeve frame 10, the brush piece 19 can fit the surface of the floor rail 11 and wipe the surface of the floor rail 11, which is beneficial to the subsequent application of lubricating oil 17 for maintenance of the floor rail 11.

[0030] Furthermore, a movable sleeve is provided with a rotating spring 22 at the other end of the rotating shaft 15, and the rotating spring 22 is movably connected to the cover box 2. The rotating spring 22 can rotate the rotating shaft 15 in the opposite direction when the cargo platform 5 rises, so that the steel cable 3 pulled out by the blocking block 4 can be smoothly wound back into the reel 20, thereby reducing the interference of the steel cable 3 on the lifting and lowering of the cargo platform 5.

[0031] The method of using this embodiment is as follows: when using the present stereoscopic warehouse storage and stacking equipment, it is necessary to first install the ground rail 11 on the equipment in the lane of the warehouse, and then install the bottom platform 7 on the ground rail 11, and then connect the equipment to the control system. At this time, the cargo platform 5 will be raised and lowered along the gantry 1 under the control of the equipment, and start to store and take out the goods. When the cargo platform 5 is placed with goods and suddenly drops, the block 4 connected to the cargo platform 5 will pull the steel cable 3, so that the steel cable 3 starts to quickly unfold from the drum 20, so that the drum 20 drives the shaft 15 to rotate quickly in the cover box 2. At this time, when the speed sensor 21 in the cover box 2 detects that the speed of the shaft 15 is too fast, it transmits a signal to the equipment control system, so that the control The system controls the electric push rod 14 to start, pushes the ratchet 13 toward the ratchet 12, so that the ratchet 12 engages with the ratchet 13, and stops the rotating shaft 15 fixed to the ratchet 12, so that the steel cable 3 stops driving the reel 20 to rotate, so that the steel cable 3 is restricted from unfolding. At this time, the block 4 will be pulled and braked under the action of the steel cable 3, so that the cargo platform 5 stops sliding. In the process of the base 7 sliding along the ground rail 11, the sleeve frames 10 on both sides of the base 7 will make the brush piece 19 slide against the ground rail 11 to clean the dust particles on the ground rail 11. Then the lubricating oil 17 in the oil storage cylinder 9 at the top of the side box 8 will be applied to the ground rail 11 along the ball 18 in the downward opening that fits the ground rail 11, so that the ground rail 11 can be maintained while sliding.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
