Description

Technical Field

[0001] This utility model relates to the field of prestressed tendon technology, and in particular to a vertical prestressed tendon positioning device. Background Technology

[0002] Vertical prestressed tendons are prestressed steel strands or high-strength steel bars arranged along the vertical direction of the structure (such as the axis of the bridge pier or the vertical direction of the component). They generate prestress through pretensioning technology to improve the stress performance of concrete components. The materials are usually high-strength steel strands (used for bridge piers) or steel bars (used for horizontal components such as beams and slabs), and they need to be fixed with anchors and sleeves.

[0003] However, existing positioning devices mostly use simple steel bar supports or temporary binding when binding vertical prestressing tendons, which makes it difficult to ensure the precise design position of the prestressing tendons. This can easily lead to misalignment and torsion. Moreover, multiple prestressing tendons need to be measured, marked, and bound one by one on-site, which is inefficient and makes it difficult to form a unified standardized operation.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main objective of this invention is to provide a vertical prestressing tendon positioning device, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vertical prestressed tendon positioning device includes a mounting base, a controller fixedly mounted on the left front end of the mounting base, an adjustment device fixedly mounted on the left end of the mounting base, a sliding groove opened on the upper end of the mounting base, a support device fixedly mounted on the upper end of the adjustment device and the upper right end of the mounting base, a binding device fixedly mounted on the support device, and a rotating device fixedly mounted on the binding device.

[0007] Preferably, the binding device includes a first connecting seat and a second connecting seat. Each of the opposite ends of the first and second connecting seats is fitted with a set of mounting screws. A binding seat is fixedly mounted on each corresponding end of the first and second connecting seats. Each of the two binding seats has several insertion holes on its corresponding end. By loosening the mounting screws on the first and second connecting seats, the two binding seats can be disassembled, allowing the device to be replaced with binding seats of the corresponding model according to the required dimensions of the vertical prestressing tendons.

[0008] Preferably, the rotating device includes a first servo motor, with a drive gear fixedly mounted on the output end of the first servo motor. A gear ring is meshed with the upper end of the drive gear, and the gear ring is fixedly mounted on the outer surface of the first connecting seat. The first servo motor drives the drive gear, which in turn drives the gear ring, causing the first connecting seat and its binding seats to rotate. This allows workers to insert the required vertical prestressing tendons one by one into the binding seats at the same position, improving worker efficiency.

[0009] Preferably, the adjustment device includes a second servo motor, with a threaded rod fixedly mounted on the output end of the second servo motor. A slider is threaded onto the outer surface of the threaded rod, and the second servo motor is fixedly mounted on the left end of the mounting base. The second servo motor drives the threaded rod to rotate within the slide groove, causing the slider on the threaded rod to slide and adjust within the groove. This causes the first hydraulic cylinder and the first connecting seat on the slider to slide to the right, allowing the other side of the vertical prestressing tendon to insert into the binding seat on the second connecting seat.

[0010] Preferably, the support device includes a first hydraulic cylinder and a second hydraulic cylinder. A first mounting bracket is fixedly installed at the output end of the first hydraulic cylinder, which is also fixedly mounted on the upper end of the slider. A second mounting bracket is fixedly installed at the output end of the second hydraulic cylinder, which is also fixedly mounted on the upper right side of the mounting base. The controller simultaneously activates both the first and second hydraulic cylinders, thereby simultaneously adjusting the height of the strapping seats mounted on them.

[0011] Preferably, the strapping seat has screw holes corresponding to the mounting screws.

[0012] Preferably, several of the aforementioned insertion holes are arranged in a ring on the binding base.

[0013] Preferably, the threaded rod is rotatably mounted in the slide groove, and the slider is slidably mounted in the slide groove.

[0014] Preferably, the No. 1 servo motor is inserted and fixedly installed at the lower right end of the No. 1 mounting bracket.

[0015] Preferably, the first connecting seat is fixedly installed at the right end of the first mounting bracket, and the second connecting seat is fixedly installed at the left end of the second mounting bracket.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When it is necessary to position and bind the vertical prestressing tendons, insert the vertical prestressing tendons into the binding seats on the No. 1 connecting seat through the insertion holes. Then, the No. 1 servo motor drives the drive gear, which in turn drives the gear ring, which in turn drives the No. 1 connecting seat and the binding seats on it to rotate. This allows the workers to insert the vertical prestressing tendons to be bound one by one into the binding seats at the same position, improving the efficiency of the workers. Then, the No. 2 servo motor drives the threaded rod to rotate in the slide groove. At this time, the slider on the threaded rod slides and adjusts in the slide groove, causing the No. 1 hydraulic cylinder on the slider and the No. 1 connecting seat to slide to the right, so that the other side of the vertical prestressing tendon is inserted into the binding seat on the No. 2 connecting seat. At this time, the workers can bind the vertical prestressing tendons.

[0017] 2. By loosening the mounting screws on connector No. 1 and connector No. 2, the two binding seats can be disassembled, allowing the device to be replaced with the corresponding model of binding seat according to the size requirements of the vertical prestressing tendons.

[0018] 3. When binding the vertical prestressing tendons, the controller simultaneously starts hydraulic cylinders No. 1 and No. 2. The hydraulic cylinders No. 1 and No. 2 drive the binding seats on them to adjust their height at the same time. This not only makes the binding height of the vertical prestressing tendons suitable for the workers, but also facilitates the unloading of the materials after binding. Attached Figure Description

[0023] The binding device 2 includes a first connecting seat 20 and a second connecting seat 21. Each connecting seat 20 and the second connecting seat 21 has a set of mounting screws 22 installed at opposite ends. Binding seats 23 are fixedly installed at corresponding ends of each connecting seat 20 and the second connecting seat 21. Several insertion holes 24 are provided at corresponding ends of the two binding seats 23. The binding seats 23 have screw holes corresponding to the mounting screws 22. The insertion holes 24 are arranged in a ring on the binding seats 23. By loosening the mounting screws 22 on the first connecting seat 20 and the second connecting seat 21, the two binding seats 23 can be disassembled, allowing the device to be replaced with binding seats 23 of the corresponding model according to the size requirements of the vertical prestressing tendons.

[0024] The rotating device 3 includes a first servo motor 30, with a drive gear 31 fixedly mounted on the output end of the first servo motor 30. A gear ring 32 is meshed with the upper end of the drive gear 31, and the gear ring 32 is fixedly mounted on the outer surface of the first connecting seat 20. The first servo motor 30 drives the drive gear 31, which in turn drives the gear ring 32. The gear ring 32 then drives the first connecting seat 20 and the binding seat 23 on it to rotate, allowing the workers to insert the vertical prestressing tendons to be bound one by one into the binding seat 23 at the same position, thus improving the efficiency of the workers.

[0025] The adjustment device 4 includes a second servo motor 40, with a threaded rod 41 fixedly mounted on the output end of the second servo motor 40. A slider 42 is threaded onto the outer surface of the threaded rod 41. The second servo motor 40 is fixedly mounted on the left end of the mounting base 1. The threaded rod 41 is rotatably mounted in the slide groove 6, and the slider 42 is slidably mounted in the slide groove 6. The second servo motor 40 drives the threaded rod 41 to rotate in the slide groove 6. At this time, the slider 42 on the threaded rod 41 slides and adjusts in the slide groove 6, causing the first hydraulic cylinder 52 and the first connecting seat 20 on the slider 42 to slide to the right, so that the other side of the vertical prestressing tendon is inserted into the binding seat 23 on the second connecting seat 21.

[0026] The support device 5 includes a first hydraulic cylinder 52 and a second hydraulic cylinder 53. A first mounting bracket 50 is fixedly installed at the output end of the first hydraulic cylinder 52, which is also fixedly installed on the upper end of the slider 42. A second mounting bracket 51 is fixedly installed at the output end of the second hydraulic cylinder 53, which is fixedly installed on the upper right side of the mounting base 1. A first servo motor 30 is inserted and fixedly installed on the lower right side of the first mounting bracket 50. A first connecting seat 20 is fixedly installed on the right side of the first mounting bracket 50, and a second connecting seat 21 is fixedly installed on the left side of the second mounting bracket 51. The controller 7 simultaneously starts the first hydraulic cylinder 52 and the second hydraulic cylinder 53, thereby simultaneously driving the strapping seat 23 on them to adjust its height. All electrical equipment in this invention is existing technology, and all electrical equipment can operate normally during trial operation. The controller 7 has its own power supply, and the controller 7 is electrically connected to the electrical equipment in this invention.

[0027] It should be noted that this utility model is a vertical prestressing tendon positioning device. When it is necessary to position and bind the vertical prestressing tendons, the controller 7 firstly activates hydraulic cylinder 52 and hydraulic cylinder 53 simultaneously. Hydraulic cylinders 52 and 53 simultaneously drive the binding seat 23 on them to adjust its height, ensuring the binding height of the vertical prestressing tendons is suitable for the workers and facilitating unloading after binding. Next, the vertical prestressing tendons are inserted into the binding seat 23 on the first connecting seat 20 through the insertion hole 24. Then, the first servo motor 30 drives the drive gear 31. The rotation of the drive gear 31 drives the gear ring 32, which in turn drives the first connecting seat 20 and its binding seat 23 to rotate, thus allowing the work to proceed smoothly. Personnel can insert the required vertical prestressing tendons one by one into the binding seat 23 at the same position, improving the efficiency of the workers. Then, the second servo motor 40 drives the threaded rod 41 to rotate in the slide groove 6. At this time, the slider 42 on the threaded rod 41 slides and adjusts in the slide groove 6, causing the first hydraulic cylinder 52 and the first connecting seat 20 on the slider 42 to slide to the right, so that the other side of the vertical prestressing tendon is inserted into the binding seat 23 on the second connecting seat 21. At this time, the workers can bind the vertical prestressing tendons. In addition, by loosening the mounting screws 22 on the first connecting seat 20 and the second connecting seat 21, the two binding seats 23 can be disassembled, so that the device can be replaced with the corresponding model of binding seat 23 according to the size requirements of the vertical prestressing tendon.
