Description

Technical Field

[0001] This utility model provides a high-load rebar coil fastening and take-up device, and in particular, a high-load rebar coil fastening and take-up device for high-speed railway track embedded parts, belonging to the field of rebar processing equipment. Background Technology

[0002] To improve the ease of handling, steel bars are generally coiled in one direction using a take-up device, which rotates the steel bars onto the multiple take-up claws of the device. Then, the take-up claws are retracted, and the coiled steel bars are unloaded for transportation.

[0003] During the concrete pouring process, in order to improve the bond strength between the steel bars and the concrete, the threads can better anchor the steel bars in the concrete when the steel bars and concrete work together, prevent relative slippage between them when the concrete is under stress, and improve the integrity and stress stability of the concrete structure. Therefore, it is necessary to process round steel bars into threaded steel bars with various thread shapes. Cold-rolled threaded steel bars are a processing form in which threads are formed on the surface of round steel bars in a cold state.

[0004] The existing rebar coil take-up device is as shown above. Figure 3 As shown, its structure is a cantilever structure, consisting of a motor 21, a reducer 22, a rebar take-up device 23, and a claw 24. The rebar take-up device 23 is directly mounted on the output shaft of the reducer 22. In this structure, the output shaft of the reducer 22 is subjected to a large force, and the bearings are frequently damaged. The coiled rebar take-up device fixes the coiled rebar at one end, which can easily cause deformation or jumping at the other end of the take-up device, damaging the entire take-up device. In addition, the claw installed at the free end of this type of take-up device cannot form a complete disc structure, and it is easy to cause defects in the end face of the product due to deformation of the claw, affecting the product quality. This type of take-up device can only produce small coiled rebar products weighing 2 tons, and cannot produce large-tonnage coiled rebar products.

[0005] In recent years, with the continuous development of cold-rolled rebar production, especially with the increasing automation of downstream processing equipment, higher requirements have been placed on the single coil weight and product quality of cold-rolled rebar coils. In the manufacturing process of high-speed rail track embedded parts, the required reinforcing steel is quite special. It not only needs to withstand large loads, but its length must also match the number of embedded parts being manufactured. If the rebar coils are replaced midway through manufacturing, it will not only affect the manufacturing speed but also the quality of the embedded parts, especially at the joints where the quality differs from the overall rebar. Therefore, embedded part manufacturers require longer single coil lengths, neater coils, and better, more stable product performance. Currently, the single coil weight of rebar coils is 2 tons, which cannot meet user requirements. Improving the take-up weight of the coil take-up device, the shape of the rebar coils, and the quality of the rebar products has become a major challenge for the company. Summary of the Invention

[0006] To address the problems of existing coil take-up devices having small tonnage, unsatisfactory coil shape, and susceptibility to malfunction, this utility model provides a high-load rebar coil fastening and take-up device specifically designed for high-speed railway track embedded parts. Its purpose is to increase the coil weight of the rebar, extend the equipment downtime interval, increase the coil diameter of the rebar, prolong the cooling time of the rebar, improve the product quality of the rebar, and meet the manufacturing needs of high-speed railway track embedded parts.

[0007] The technical solution of this utility model is: a special high-load steel bar coil fastening and take-up device for high-speed rail track embedded parts, including a take-up device, a coil support mechanism is provided opposite the center of the take-up device, the coil support mechanism is provided on a moving trolley, the moving trolley is rolled on a moving guide rail, the moving guide rail is provided on a base, a hydraulic drive mechanism is provided on the base, the hydraulic rod of the hydraulic drive mechanism is connected to the coil support mechanism, the coil support mechanism is opposite to the center of the take-up device, and the rightmost end of the take-up device is connected to a reduction motor through a drive sprocket and a chain; Furthermore, the take-up device includes a base plate, on which, starting from the side of the coiled screw support mechanism, from left to right, are arranged the take-up device arc plate, coiled screw baffle, take-up device bearing seat, take-up tensioning mechanism, and take-up device drive sprocket outside the spindle. The take-up tensioning mechanism is connected to the take-up device arc plate. Furthermore, the base of the coiled screw support mechanism is provided with a lifting platform, a second coiled screw baffle, and a support bearing seat in sequence from right to left, starting from the take-up device. The support bearing seat is supported by a bracket between itself and the base. The second coiled screw baffle and the first coiled screw baffle on the take-up device are arranged opposite each other. Both are circular baffles with their centers facing each other. The central shaft of the second coiled screw baffle and the support bearing seat are the same shaft. Furthermore, the take-up arc plate includes multiple take-up arc plates with the same structure. One of the coiled screw baffles is perpendicular to the spindle, and the spindle is provided with a thrust bearing and a take-up bearing seat. Furthermore, the take-up tensioning mechanism includes a hydraulic cylinder, which is located on the right side of the take-up device with the cylinder rod facing to the left. The cylinder rod is connected to a spindle via a coupling. Multiple sliding sleeves are connected to the outer circumference of the left end of the spindle at the same index. Each sliding sleeve has a connecting rod, a bent plate, and a support sequentially hinged to its outer circumference from the inside to the outside at both ends. The support is fixed to the inner circumference of the arc plate of the take-up device.

[0008] By installing a coiled screw support mechanism opposite the center of the take-up coiler, a hydraulic drive mechanism within the support mechanism can be used to drive the coiled screw support mechanism along a movable guide rail on the base, closer to the take-up coiler. By installing two coiled screw baffles, one with its center opposite to the center, on the take-up coiler and the support mechanism respectively, the coiled screw becomes more compact under the action of the hydraulic drive mechanism, changing the previous loose structure; this also improves the appearance quality of the coiled screw. By installing a take-up tensioning mechanism in the take-up coiler, the mandrel moves axially under the action of the hydraulic cylinder of the tensioning mechanism. This further drives multiple sliding sleeves on the left end of the mandrel to move axially. Under the action of these sliding sleeves, multiple hinged connecting rods and multiple bent plates sequentially cause the arc plates fixed to the take-up coiler on the support to expand or contract radially, thereby expanding the inner ring of the coiled screw. This facilitates the disengagement of the multiple arc plates from the take-up coiler after contraction. The inner ring of the spiral rebar is connected to a large motor via a sprocket at the far right end of the take-up device. This connection improves driving power and stability. The large motor can also drive a large spiral coil, increasing its weight and extending the cooling time of the rebar. Compared to the existing 2-ton small spiral coil, this increases to 5 tons. This reduces packaging time by 1.5 times and subsequent coil change times by 1.5 times, improving overall production efficiency. The aging time is also longer, and the elongation rate of the rebar is improved. This reduces stress during processing, enhancing the quality of the rebar. This invention increases the coil weight of the rebar, extends equipment downtime, increases the coil diameter, extends the cooling time, and improves product quality, meeting the manufacturing requirements of high-speed rail track embedded parts.

Detailed Implementation

[0013] The specific technical solution of this utility model will be described in detail below with reference to the accompanying drawings. In the following description, the left and right directions refer to the left and right directions shown in the figures.

[0014] The technical solution of this utility model is: a high-load steel bar coil fastening and take-up device for high-speed railway track embedded parts. Figure 1 This is a schematic diagram of the overall structure of this utility model. Figure 2 This is an axial cross-sectional schematic diagram of the tensioning mechanism of the take-up coil. The high-load steel bar coil fastening take-up device for high-speed rail pre-embedded parts includes a take-up coil 10. A coil support mechanism 20 is arranged opposite the center of the take-up coil 10. The coil support mechanism 20 is arranged on a moving trolley 7. The moving trolley 7 is rotatably arranged on a moving guide rail 11. The moving guide rail 11 is arranged on a base 12. A hydraulic drive mechanism 9a is also arranged on the base 12. The hydraulic rod of the hydraulic drive mechanism is connected to the coil support mechanism 20. The center of the coil support mechanism 20 is opposite to that of the take-up coil 10. The rightmost end of the take-up coil 10 is connected to a reduction motor through a drive sprocket and a chain.

[0015] The take-up device 10 includes a base plate 5. Starting from the side of the coiled screw support mechanism, the base plate 5 is provided with the following components from left to right: a take-up device arc plate 3, a coiled screw baffle 1a, a take-up device bearing seat 2, a take-up tensioning mechanism 4, and a take-up device drive sprocket 25. The take-up tensioning mechanism 4 is connected to the take-up device arc plate 3.

[0016] The base 12 of the spiral support mechanism 20 is provided with a lifting platform 8, a spiral baffle 1b, and a support bearing seat 6 arranged sequentially from right to left, starting from the take-up device 10. The support bearing seat 6 is supported by a bracket 6a between it and the base 12. The spiral baffle 1b is arranged opposite to the spiral baffle 1a on the take-up device 10. Both are circular baffles and are connected to their respective spindles. Their centers are opposite each other. The spiral baffle 1b and the support bearing seat 6 have the same axis of rotation. The spiral baffle 1b is perpendicular to the axis of rotation.

[0017] The take-up arc plate 3 includes multiple take-up arc plates 3 with the same structure. The coiled screw baffle 1a is perpendicular to the spindle 13a. The spindle 13a is provided with a thrust bearing 14 and a take-up bearing seat 2.

[0018] The take-up tensioning mechanism 4 includes a hydraulic cylinder 9b, which is located on the right side of the take-up device 10. The cylinder rod of the hydraulic cylinder 9b faces to the left. The cylinder rod of the hydraulic cylinder 9b is connected to a spindle 13a through a coupling 13b. Multiple sliding sleeves 15 are connected to the outer circumference of the left end of the spindle 13a at the same index. Each sliding sleeve 15 has a connecting rod 16, a bending plate 17 and a support 18 connected sequentially from the inside to the outside at both ends of its outer circumference. The support 18 is fixed to the inner circumference of the arc plate of the take-up device.

[0019] By providing a coiled screw support mechanism 20 opposite the center of the take-up coil 10, the hydraulic drive mechanism 9a within the coiled screw support mechanism 20 can be used to drive the coiled screw support mechanism 20 along the movable guide rail 11 on the base 12 near the take-up coil 10. By providing coiled screw baffles 1a and 1b with opposite centers on the take-up coil 10 and the coiled screw support mechanism 20 respectively, the coiled screw can be made more compact under the action of the hydraulic drive mechanism 9a, changing the previous loose structure; at the same time, it can also improve the appearance quality of the coiled screw. By providing a take-up tensioning mechanism 4 in the take-up coil 10, the spindle 13a can be moved axially under the drive of the hydraulic cylinder 9b of the tensioning mechanism 4, which further drives the multiple sliding sleeves 15 on the left end of the spindle 13a to move axially. Under the drive of the multiple sliding sleeves 15, the multiple connecting rods 16 and multiple bent plates 17 connected together sequentially drive the support 18 fixed to the take-up coil arc plate 3 to expand or contract radially, thereby expanding the inner circle of the coiled screw, which is beneficial. After shrinking, the multiple take-up arc plates 3 disengage from the inner ring of the coiled rebar. By setting a take-up drive sprocket 19 at the rightmost end of the take-up 10, and connecting it to the output shaft of the reduction motor via a chain, a large motor can be connected to improve driving power and stability. At the same time, a large motor can be used to drive a large coiled rebar, increasing the weight of the coiled rebar, extending the unloading time of the rebar coiled rebar, and extending the cooling time of the threaded rebar. Compared with the existing 2-ton small coiled rebar products, the weight of the coiled rebar is increased to 5 tons. In the production process, the packaging time can be reduced by 1.5 times, and the subsequent processes can reduce the coil change time by 1.5 times, which can improve the overall production efficiency. The corresponding aging time is also longer, and the elongation index of the rebar will also be improved accordingly. The stress brought by the rebar during the processing is reduced, and the quality of the rebar is improved. Using this utility model, the weight of the coiled rebar can be increased, the equipment downtime interval can be extended, the coiled diameter of the rebar can be increased, the cooling time of the rebar can be extended, and the product quality of the rebar can be improved, meeting the manufacturing needs of high-speed rail track embedded parts.
