Description

Technical Field

[0002] The steel bar centering clamping device used in prestressed concrete construction is a device specially used to fix and position prestressed steel bars. The main function of this device is to accurately position and fix the prestressed steel bars during the prestressed concrete construction process to ensure the accurate position of the steel bars and prevent the quality of the concrete structure from being affected by the displacement of the steel bars. At the same time, by adjusting the clamping force of the clamping head, the steel bars can be effectively prevented from sliding during the construction process to ensure the safety of the construction.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4As shown, the utility model provides a technical solution: a steel bar centering clamping device for prestressed concrete construction, comprising a positioning box 1, a positioning frame 2 is slidably connected to the two ends of the interior of the positioning box 1, and a plurality of positioning grooves 201 are provided on one side of the outer wall of the positioning frame 2, a group of threaded shafts 101 are rotatably connected to both ends of the interior of the positioning frame 2, and the threaded shafts 101 are located on both sides of the interior of the positioning frame 2, the center of the outer wall of the threaded shaft 101 is connected to one side of the top surface of the positioning frame 2 through a thread, and one side of the interior of the positioning frame 2 is rotatably connected to the center of the outer wall of the threaded shaft 101, a clamping motor 202 is fixedly connected to the bottom end of the interior of the positioning frame 2, and a plurality of groups of positioning plates 203 are slidably connected to the interior center of the positioning frame 2, the positioning plates 203 are respectively located at the upper and lower ends of the inner wall of the positioning groove 201, and the positioning plates 203 are slidably connected to the upper and lower ends of the inner wall of the positioning groove 201, a control motor 102 is fixedly connected to one side of the outer wall of the positioning box 1, and the output end of the control motor 102 is rotatably connected to the outer wall of the bottom of the threaded shaft 101.

[0024] A plurality of steel bars are passed through the inner center of the positioning groove 201 into the positioning box 1, and then passed out from the inner center of the positioning groove 201 corresponding to the other end of the positioning box 1, and after the steel bars are changed to a specified length, the clamping motor 202 is driven to drive the bidirectional threaded rod 206 on one side of the inner part of the positioning groove 201 through the conical teeth on the outer wall of the positioning shaft 205. Since one side of the inner part of the positioning plate 203 is penetrated by the slide rail 204, and the positioning plate 203 can only slide vertically along the outer wall of the slide rail 204, when the bidirectional threaded rod 206 is driven to rotate by the output end of the clamping motor 202, the bidirectional threaded rod 206 drives the positioning plate 203 to move toward the inner center of the positioning groove 201 along the outer wall of the slide rail 204 through the outer wall thread, and conflicts with the outer wall of the steel bar, so as to fix the steel bar. After positioning, the steel bar is positioned, by making the threaded shaft 101 pass through both sides of the interior of the positioning frame 2, and realizing the rotation linkage between the threaded shaft 101, the driving rod 103, and the transmission rod 104 through the driving teeth 105, and after the outer wall of one end of one of the driving rods 103 is fixedly connected to the output end of the control motor 102, by driving the control motor 102, the several threaded shafts 101 in the positioning box 1 can be rotated synchronously, and the positioning frame 2 is driven along the outer wall thread of the threaded shaft 101, thereby prompting the positioning frame 2 to slide vertically on the outer wall of the positioning box 1 along the outer thread of the threaded shaft 101, and the position of the steel bar can be fine-tuned. Therefore, the device can accurately adjust the position of the steel bar in the positioning box 1 by operating the control motor 102.

[0025] like Figure 1-4As shown, one side of the inner wall of the positioning groove 201 is fixedly connected with a slide rail 204, and the slide rail 204 is located on the inner side of the positioning plate 203, one side of the outer wall of the slide rail 204 is connected through the outer wall of the positioning plate 203, and the inner side of the positioning plate 203 is slidably connected with the outer wall of one side of the slide rail 204, the bottom end of the interior of the positioning frame 2 is rotatably connected with a positioning shaft 205, and one end of the outer wall of the positioning shaft 205 penetrates through the inner wall of the positioning frame 2 and is fixedly connected to the output end of the clamping motor 202, and the interior of the positioning groove 201 is away from the side of the slide rail 204. A two-way threaded rod 206 is dynamically connected, and the two-way threaded rod 206 is located on one side of the interior of the positioning plate 203, one end of the outer wall of the two-way threaded rod 206 is connected to one side of the top surface of the positioning plate 203 through a thread, and one side of the interior of the positioning plate 203 is rotatably connected to one end of the outer wall of the two-way threaded rod 206, the outer wall of the bottom end of the two-way threaded rod 206 and the center of the outer wall of the positioning shaft 205 are fixedly connected with conical teeth, and the two-way threaded rod 206 is rotatably connected to the top of the outer wall of the positioning shaft 205 through the conical teeth fixedly connected to the bottom end of the outer wall.

[0026] After a plurality of steel bars are inserted into the positioning box 1 from the inner center of the positioning groove 201 and then passed out from the inner center of the positioning groove 201 corresponding to the other end of the positioning box 1, and the steel bars are changed to a specified length, the clamping motor 202 is driven to drive the bidirectional threaded rod 206 on one side of the inner part of the positioning groove 201 through the conical teeth on the outer wall of the positioning shaft 205. Since one side of the inner part of the positioning plate 203 is penetrated by the slide rail 204, and the positioning plate 203 can only slide vertically along the outer wall of the slide rail 204, when the bidirectional threaded rod 206 is driven to rotate by the output end of the clamping motor 202, the bidirectional threaded rod 206 drives the positioning plate 203 to move simultaneously along the outer wall of the slide rail 204 toward the inner center of the positioning groove 201 through the outer wall thread, and contacts the outer wall of the steel bar, so that it can be positioned, so that the device can cooperate with the slide rail 204 through the bidirectional threaded rod 206 to achieve simultaneous positioning of a plurality of steel bars.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a group of driving rods 103 are rotatably connected to the bottom end of the interior of the positioning box 1, and one end of the outer wall of one of the driving rods 103 penetrates through one side of the inner wall of the positioning box 1 and is fixedly connected to the output end of the control motor 102, and a transmission rod 104 is rotatably connected to the top end of the interior of the positioning box 1, and the transmission rod 104 is located on one side of the interior of the positioning box 1, and driving teeth 105 are fixedly connected to the upper and lower ends of the outer wall of the threaded shaft 101, the outer wall of the driving rod 103 near both ends, and the two ends of the outer wall of the transmission rod 104, and the threaded shaft 101, the driving rod 103 and the transmission rod 104 are all rotatably connected through the driving teeth 105, and the upper and lower ends of the outer wall of the threaded shaft 101, the outer wall of the driving rod 103 near both ends, and the two ends of the outer wall of the transmission rod 104 are all fixedly connected with driving teeth 105, and the threaded shaft 101, the driving rod 103 and the transmission rod 104 are all rotatably connected through the driving teeth 105.

[0028] After the steel bars are positioned, the threaded shaft 101 is passed through both sides of the positioning frame 2, and the driving teeth 105 are used to realize the rotation linkage between the threaded shaft 101, the driving rod 103, and the transmission rod 104. After the outer wall of one end of one of the driving rods 103 is fixedly connected to the output end of the control motor 102, the control motor 102 is driven to synchronously rotate the several threaded shafts 101 in the positioning box 1, and the positioning frame 2 is driven along the outer wall thread of the threaded shaft 101, thereby prompting the positioning frame 2 to slide vertically on the outer wall of the positioning box 1 along the outer thread of the threaded shaft 101, so as to fine-tune the position of the steel bars. Therefore, the device can accurately adjust the position of the steel bars in the positioning box 1 by operating the control motor 102.

[0029] Working principle: A plurality of steel bars are passed through the center of the positioning groove 201 into the positioning box 1, and then passed out from the center of the positioning groove 201 corresponding to the other end of the positioning box 1, and after the steel bars are changed to a specified length, the clamping motor 202 is driven to drive the bidirectional threaded rod 206 on one side of the inner part of the positioning groove 201 through the conical teeth on the outer wall of the positioning shaft 205. Since one side of the inner part of the positioning plate 203 is penetrated by the slide rail 204, and the positioning plate 203 can only slide vertically along the outer wall of the slide rail 204, when the bidirectional threaded rod 206 is driven to rotate by the output end of the clamping motor 202, the bidirectional threaded rod 206 drives the positioning plate 203 along the outer wall of the slide rail 204 to the positioning groove 201 at the same time through the outer wall thread. The inner center moves and contacts with the outer wall of the steel bar to position it. After the steel bar is positioned, the threaded shaft 101 passes through the two sides of the inner part of the positioning frame 2, and the driving teeth 105 are used to realize the rotation linkage between the threaded shaft 101, the driving rod 103, and the transmission rod 104. After the outer wall of one end of one of the driving rods 103 is fixedly connected to the output end of the control motor 102, the control motor 102 is driven to synchronously rotate the several threaded shafts 101 in the positioning box 1, and the positioning frame 2 is driven along the outer wall thread of the threaded shaft 101, thereby prompting the positioning frame 2 to slide vertically on the outer wall of the positioning box 1 along the external thread of the threaded shaft 101, so as to fine-tune the position of the steel bar.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
