Description

Technical Field

[0001] The utility model belongs to the technical field of PC steel bar stacking, and particularly relates to a PC steel bar stacking device. Background Art

[0002] PC steel bar, the full name of which is steel bar for prestressed concrete, has a very broad market in the international market, especially in Asia, due to its high strength and toughness, low relaxation, strong bond with concrete, good weldability, upset forging, and material saving. In the production process of PC steel bar, after multiple processing steps, the finished PC steel bar needs to be sorted and stacked for easy transportation and utilization. Round PC steel bar, that is, steel bar for prestressed concrete, is a high-strength and high-toughness bar. It is widely used in prestressed concrete structures to increase the strength and rigidity of the structure. The round PC steel bar generates pre-compression stress through tensioning, which can offset part or all of the tensile stress generated by external loads, thereby improving the bearing capacity and crack resistance of the structure. It has the advantages of low relaxation, strong bond with concrete, good weldability, upset forging, and can save materials.

[0003] A Chinese patent with publication number "CN219791728U" discloses a PC steel bar stacking device, which includes a workbench, a rotary hydraulic cylinder is fixedly connected to one side of the top of the workbench, a mounting seat is fixedly connected to the output end of the rotary hydraulic cylinder, a swing assembly 1, a swing assembly 2, a rotating assembly, a clamping assembly, and a gear assembly are sequentially arranged on the top of the mounting seat, a camera is arranged on one side of the mounting seat, a conveyor belt, a stacking box, and PC steel bars are arranged on one side of the top of the workbench, and a support leg is fixedly connected to the bottom of the workbench. The PC steel bar stacking device described in the utility model can be suitable for the stacking of PC steel bars of different models and sizes by arranging a swing assembly 1, a swing assembly 2, a rotating assembly, a clamping assembly, a gear assembly, a conveyor belt, a stacking box, a camera, etc. At the same time, it is convenient to take PC steel bars in all directions and neatly stack the PC steel bars in the stacking box, and the stacking efficiency is high and the degree of automation is high.

[0004] Although the above device can assist in performing a good carrying function during use, its top adopts a clamping and rotating carrying design. During the rotating carrying period, the clamping assembly will be in a circular shape to assist in movement. During the movement, the clamping assembly will inevitably extend out of the workbench. It can be seen that it needs to occupy a large space during transportation, and its carrying structure is relatively complicated. The clamping assembly only uses two sets of clamping plates for extrusion and clamping, and the above-mentioned steel rod is round, and the circular structure is an unstable structure as a whole. The bottom of the clamping plate lacks a limiting structure. During the clamping and fixing process, the steel rod is very easy to fall off. It can be seen that its overall carrying has certain defects and shortcomings, so it needs to be improved. Utility Model Content

[0024] refer to Figures 1 to 4 A PC steel bar stacking device of the present embodiment comprises a base 1, support legs 2 are fixedly installed at the four corners of the top of the base 1, a top seat 3 is fixedly installed on the top of the support legs 2, a concave seat 4 is fixedly installed on one side of the top of the top seat 3, a conveyor belt 5 is rotatably connected to the inner side of the concave seat 4, a storage box 6 is placed on the top of the conveyor belt 5, a PC steel bar body 8 is placed inside the storage box 6, a shifting mechanism 7 is fixedly installed on the top rear side of the base 1, a top frame 11 is fixedly installed on the top of the shifting mechanism 7, a telescopic cylinder 10 is fixedly installed on the outer end of the top frame 11, and a clamping mechanism 9 is fixedly installed on the output end of the telescopic cylinder 10 through the top frame 11;

[0025] The clamping mechanism 9 includes a base 91, which is fixedly mounted on the bottom of the telescopic cylinder 10. A clamping assembly 92 is fixedly mounted on the bottom of the base 91. Fixed plates 94 are fixedly mounted on both sides of the base 91. Both ends of the outer sides of the fixed plates 94 are movably mounted with linkage limit assemblies 93. The linkage limit assemblies 93 are arranged on both sides of the clamping assembly 92. The coordinated use of the transfer mechanism 7 and the clamping mechanism 9 makes the transportation of the PC steel rod more convenient. The transfer mechanism 7 can drive the clamping mechanism 9 to move horizontally through the extension and contraction of the telescopic cylinder 10, thereby realizing the clamping and transportation of the PC steel rods at different positions. The clamping mechanism 9 The design itself is also very unique. The clamping assembly 92 at the bottom of the base 91 can be adjusted according to the size of the PC steel rod to achieve stable clamping of the steel rod. At the same time, the linkage limit assembly 93 on the outside of the fixed plate 94 can further limit the steel rod after the clamping assembly 92 clamps the steel rod, ensuring that the steel rod will not loosen or fall during transportation, thereby improving the safety and stability of the entire device. In addition, the design of the conveyor belt 5 also greatly improves work efficiency. Through the conveyor belt 5, the PC steel rods in the storage box 6 can be conveniently transported to the required position, reducing the trouble of manual handling and improving the accuracy of work.

[0026] refer to Figure 1-Figure 3The adjustment mechanism 7 includes a guide rail 71, which is fixedly installed on the top rear side of the base 1, and the inside of the guide rail 71 is rotatably connected to a first screw rod 72, and the outer surface of the first screw rod 72 is threadedly connected to a slider 73, and the outer side of the slider 73 is fixedly connected to the top frame 11. A first motor 74 is fixedly installed on one side of the guide rail 71, and the output end of the first motor 74 is fixedly connected to one end of the first screw rod 72. The guide rail 71 is firmly installed on the top rear side of the base 91 to provide stable support for the entire adjustment process. The first screw rod 72 is rotatably connected to the inside of the guide rail 71 and is tightly combined with the slider 73 through a threaded connection. The outer side of the slider 73 is fixedly connected to the top frame 11 to ensure that when the screw rod rotates, the top frame 11 can move accordingly. 4 is installed on one side of the guide rail 71, and its output end is connected to one end of the first screw rod 72 to provide power for the screw rod to rotate. In actual use, it is only necessary to start the first motor 74 to drive the first screw rod 72 to rotate inside the guide rail 71. The rotation of the screw rod then drives the slider 73 to slide in the guide rail 71 to achieve the lateral displacement of the top frame 11. This design enables the device to flexibly adjust the transportation displacement, whether it is a long distance or a short distance, it can be completed quickly and accurately, which not only improves the transportation efficiency, but also enhances the flexibility and convenience of the device during use, making the transportation of PC steel bars easier and more efficient. At the same time, compared with the arc displacement method, linear displacement can save the required space for use and facilitate the use of the device.

[0027] refer to Figure 1-Figure 4The clamping assembly 92 includes a slide groove 921 and a second motor 922. The slide groove 921 is opened in the middle of the bottom of the base 91. The inside of the slide groove 921 is rotatably connected to the second screw rod 923. The second motor 922 is fixedly installed on one side of the base 91. The output end of the second motor 922 is fixedly connected to one end of the second screw rod 923. The two ends of the second screw rod 923 have opposite thread rotation directions. Both ends of the second screw rod 923 are threadedly connected to a movable block 924. A side plate 927 is fixedly installed at the bottom of the movable block 924. The design of the slide groove 921 provides a rotation space for the second screw rod 923 and enables the movable block 924 to slide along the slide groove 921. The second motor 922 serves as a power source to drive the second screw rod 923 to rotate. Due to the rotation of the second screw rod 923 The threads at both ends rotate in opposite directions. When the second screw rod 923 rotates, the two movable blocks 924 will move closer to or farther away from each other along the slide groove 921, thereby clamping and releasing the PC steel rod body 8. The side plate 927 is installed at the bottom of the movable block 924. When the movable block 924 moves, the side plate 927 will also move accordingly. The design of the side plate 927 can ensure the stable clamping of the PC steel rod body 8 to prevent the steel rod from shaking or falling off during transportation. In addition, the design of the clamping assembly 92 also has good flexibility and adjustability. By adjusting the rotation speed and direction of the second motor 922, the clamping force of the PC steel rod body 8 can be accurately controlled. At the same time, the length of the slide groove 921 can also be adjusted as needed to accommodate PC steel rod bodies 8 of different sizes.

[0028] refer to Figure 1-Figure 3 A guide seat 12 is fixedly installed on one side of the top of the base 91, and a guide groove 13 is provided on the upper end of the guide seat 12. The guide seat 12 is fixed on one side of the top of the base 91, and a guide groove 13 is provided on its upper end. The main function of the guide seat 12 is to assist in guiding the loaded storage box 6. During the stacking process, the storage box 6 can be smoothly guided to the guide seat 12 with the help of the conveyor belt 5 or other conveying mechanisms, and move along the direction of the guide groove 13. The design of the guide groove 13 is very critical. It can not only ensure the stability of the storage box 6 during the movement and prevent it from lateral movement or deviation, but also guide the storage box 6 to move along a predetermined path to ensure the accuracy and efficiency of stacking. Therefore, through the cooperation of the guide seat 12 and the guide groove 13, the device can quickly guide the storage box 6, thereby improving the speed and accuracy of stacking, which not only facilitates the use of the device, but also improves the work efficiency and reduces the difficulty of operation.

[0029] refer to Figure 1-Figure 4The overall cross-sectional shape of the guide rail 71 and the slide groove 921 is set in a convex shape, and the overall cross-sectional shape of the slider 73 and the movable block 924 is also set in a convex shape. The outer surface of the slider 73 and the inner wall of the guide rail 71 are provided with wear-resistant gaskets. The convex cross-sectional design of the guide rail 71, the slide groove 921, the slider 73 and the movable block 924, as well as the addition of wear-resistant gaskets, have significantly improved the overall stability and reliability of the PC steel bar stacking device. The following is a detailed analysis of these designs. First, the convex cross-sectional design makes the guide rail 71, the slide groove 921, the slider 73 and the movable block 924 fit more tightly. The design is close and stable. It reduces the shaking and deviation during the sliding process, thereby improving the stability of the device during operation. In addition, the convex cross-sectional shape can effectively disperse the pressure generated by the slider 73 and the movable block 924 during the sliding process, reduce wear and extend the service life. Secondly, the addition of wear-resistant gaskets further enhances the stability and durability of the device. The wear-resistant gaskets are usually made of highly wear-resistant materials, which can effectively reduce the friction between the slider 73 and the inner wall of the guide rail 71 and reduce the wear rate. At the same time, the wear-resistant gaskets can also play a buffering role to reduce the damage to the device caused by vibration or impact.

[0030] refer to Figure 1-Figure 4 , electromagnets 925 are fixedly installed at the four corners of the outer side of the side plate 927, and the inner ends of the electromagnets 925 penetrate the side plate 927 to fix a clamping plate 926. The design of fixing the electromagnets 925 at the four corners of the outer side of the side plate 927 and fixing the clamping plate 926 at the inner ends of the electromagnets 925 through the side plate 927 does provide a more stable and reliable clamping and positioning function for the PC steel bar stacking device. The electromagnet 925, as a device that can generate a magnetic field using electric current, is cleverly applied to the clamping mechanism 9 here. When the electromagnet 925 is energized, it will generate a strong magnetic attraction, which can act on the clamping plate 926, making the clamping plate 926 fit more closely to the PC The setting of the clamping plate 926 on the surface of the steel bar body 8 further enhances the clamping effect. Since the clamping plate 926 is a component that directly contacts the PC steel bar body 8, its material and design need to take into account the compatibility with the steel bar and the clamping stability. Through the magnetic attraction of the electromagnet 925, the clamping plate 926 can firmly clamp the PC steel bar body 8 to prevent shaking or falling off during transportation. This design not only improves the clamping stability, but also enables the clamping mechanism 9 to adapt to PC steel bar bodies 8 of different sizes and shapes. Because the magnetic attraction of the electromagnet 925 can be controlled by adjusting the current, the clamping force can be adjusted as needed, thereby achieving stable clamping of steel bars of different specifications.

[0031] refer to Figure 1-Figure 4The linkage limit assembly 93 includes a limit rod 931, which is rotatably connected to the middle part of the outer side of the clamping plate 926. The upper end of the limit rod 931 is sleeved with a sleeve frame 932. The upper end of the sleeve frame 932 is rotatably connected to the two ends of the outer side of the fixing plate 94. The overall cross-sectional shape of the limit rod 931 is L-shaped, and the inner end of the limit rod 931 is provided with an inclined surface 933. The design of the linkage limit assembly 93 does provide stronger stability and reliability for the clamping mechanism 9 of the PC steel bar stacking device. The assembly works in conjunction with the clamping assembly 92 to jointly achieve stable clamping and positioning of the PC steel bar body 8. Specifically, the linkage limit assembly 93 includes a limit rod 931, which is rotatably connected to the middle part of the outer side of the clamping plate 926. When the side plate 927 in the clamping assembly 92 moves, it will drive the limit rod 931 to rotate accordingly. Due to the overall cross-sectional shape of the limit rod 931 The shape is L-shaped, and an inclined surface 933 is provided at its inner end. This design enables the limit rod 931 to generate an inward thrust when rotating, thereby further enhancing the stability of clamping. At the same time, a sleeve frame 932 is sleeved on the upper end of the limit rod 931, and the upper end of the sleeve frame 932 is rotatably connected to the two ends of the base 91. This design enables the limit rod 931 to be restricted and guided by the sleeve frame 932 when rotating, thereby ensuring the stability and reliability of the rotation of the limit rod 931. When the side plate 927 clamps the PC steel bar body 8, it drives the limit rod 931 to rotate. Due to the design of the inclined surface 933 at the inner end of the limit rod 931, an inward thrust can be generated during the rotation process, thereby further stabilizing the clamping of the PC steel bar. At the same time, the sleeve frame 932 restricts and guides the rotation of the limit rod 931, ensuring that the limit rod 931 can rotate according to the predetermined path.

[0032] Principle and advantages of use: By setting the adjustment mechanism 7, the device can be operated by starting the first motor 74 during use, and the first motor 74 is used to drive the screw rod to rotate. The screw rod is located inside the guide rail 71 and rotates, which can assist in driving the slider 73 to slide and displace laterally inside the guide rail 71. By sliding the slider 73 laterally, the top frame 11 can be assisted in lateral displacement. After the top frame 11 moves to the outside of the top seat 3, the telescopic cylinder 10 can be started to push the clamping mechanism 9 to move downward to clamp and position the PC steel bar body 8. At this time, the first motor 74 is started again to rotate and run in the opposite direction, and the telescopic cylinder 10 is driven to reset at the same time, which can assist in driving the clamping mechanism 9 to move upward and move toward the storage box 6. At this time, the clamping mechanism 9 can be started to discharge the PC steel bar body 8, and the PC steel plate body can fall into the storage box 6. The linear transmission setting is adopted. Compared with the rotating transfer design in the original technical means, the entire transportation process can be located on the top of the top seat 3 during the overall transportation. Compared with the rotating transportation design, it saves more space and can improve the overall convenience of use of the device.

[0033] By setting the clamping mechanism 9, during use, the device can cooperate with the transfer mechanism 7 through the telescopic cylinder 10 to move, so that the clamping assembly 92 can be moved to the PC steel plate body that needs to be transported. By starting the second motor 922, the second motor 922 can drive the second screw rod 923 to rotate inside the slide groove 921. The second screw rod 923 rotates and the threads at both ends of the second screw rod 923 rotate in opposite directions, thereby assisting in driving the movable blocks 924 at both ends of the slide groove 921 to move relative to each other, and the two sets of side plates 927 can be flexibly adjusted to move relative to each other. At this time, the clamping plate 926 on the inner side of the side plate 927 can assist in clamping the PC steel bar body 8. By starting the operation of the electromagnet 925, the magnetic force generated by the electromagnet 925 can be used to adsorb the PC steel bar body 8. At the same time, during the clamping process, the movement of the clamping plate 926 can drive the sleeve frame 932 and the limit rod 931 to rotate in conjunction with each other. At this time, the adaptive sliding and extension of the limit rod 931 and the sleeve frame 932 can cause the limit rod 931 to rotate, which can cause the limit rod 931 to further limit the PC steel bar body 8. At the same time, the design of the inclined surface 933 can assist in guiding and limiting during the clamping positioning, which can prevent the PC steel bar body 8 from falling off during transportation, and can improve the stability of the overall PC steel bar body 8 of the device during transportation.
