Description
Technical Field
[0001] This utility model relates to the field of positioning clamp technology, and in particular to a multi-angle positioning clamp for a rebar tying jig. Background Technology
[0002] The rebar tying jig for subway track slabs is a special tool used for the construction of rebar tying in subway track slabs. It is mainly used to fix and position the rebars to ensure accurate positioning and uniform spacing, thereby guaranteeing the quality and performance of the track slabs.
[0003] The steel binding jig consists of a steel base plate, a steel reinforcement baffle, a steel reinforcement support plate, and a positioning steel frame. By setting various steel reinforcement positioning slots, grooves, and positioning steel frames on the steel base plate, the steel reinforcement of the subway track slab is placed in the corresponding position and then bound and fixed, thereby ensuring the accuracy and stability of the steel reinforcement position. However, it has the following shortcomings in use.
[0004] The side end of the binding jig is fixed in a fixed position by bolts and clamps, which means that the binding jig can only maintain a fixed angle. This means that the same set of jigs can only be used for a single specification of track slab, thus limiting the versatility of the jig. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a multi-angle positioning clamp for rebar tying jigs. This solves the technical problem that the side end of the tying jig is fixed in a fixed position by bolts and clamps, which means that the tying jig can only maintain a fixed angle and the same set of jigs can only be used for a single specification of track slab, thus limiting the versatility of the jig.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-angle positioning clamp for a rebar tying jig includes a jig frame and two support plates. The jig frame has slots at both ends. The jig frame also includes...
[0008] Four positioning components are provided, each of which is disposed on the side end of the support plate. Each positioning component includes an insert plate and a guide plate. Two card holders are fixedly installed on the side end of each insert plate, and a connecting strip is rotatably installed inside each card holder.
[0009] Preferably, each of the support plates has two adjustment frames fixedly installed on its side end, and each adjustment frame has a knob rotatably installed on its outer side;
[0010] Each of the adjusting frames has a threaded push rod rotatably mounted on both sides, and a transmission plate is rotatably mounted on the surface of each threaded push rod. The thread helix angle of each threaded push rod and transmission plate is less than the friction angle.
[0011] Preferably, the end of each connecting strip is rotatably connected to the top of the transmission plate;
[0012] Each of the support plates is provided with a drive assembly at its side end. Each drive assembly includes a fixed column, a drive wheel, and a rotating shaft, one end of which is connected to a motor.
[0013] One end of each of the drive wheels is rotatably connected to the frame, and each of the fixed posts abuts the surface of the rotating shaft.
[0014] Compared with the prior art, the present invention has the following beneficial effects;
[0015] In this invention, during the movement of the transmission plate, a thrust is generated on the connecting strip that is rotatably connected to its top. The connecting strip rotates inside the card holder, which is fixedly installed on the side of the insert plate. When the connecting strip rotates, it generates a thrust on one end of the insert plate, causing the insert plate to rotate on the side of the guide plate, thereby adjusting the tilt angle of the jig frame, which makes it convenient for workers to tie steel bars at different angles.
[0016] In this invention, the rotating threaded push rod rotates inside the transmission plate, generating a thrust on the transmission plate and causing it to slide at both ends of the adjustment frame. At the same time, the threaded push rod stops rotating, and the threaded push rod and the transmission plate can lock themselves in place. They synchronously push the transmission plate to move in the same direction, which can adjust the distance between the two insert plates. This allows for the positioning and installation of fixture frames of different specifications, improving the versatility and applicability of the fixture. Attached Figure Description

[0023] This application provides a multi-angle positioning clamp for a rebar tying jig, effectively solving the problem that the side end of the tying jig is fixed in a fixed position by bolts and clamps, which results in the tying jig only being able to maintain a fixed angle. This limits the use of the same jig for only a single specification of track plate, restricting the jig's versatility. During the movement of the transmission plate, a thrust is generated on the connecting bar rotatably connected to its top. The connecting bar rotates inside the clamp, which is fixedly installed on the side end of the insert plate. When the connecting bar rotates, it generates a thrust on one end of the insert plate, causing the insert plate to rotate on the side end of the guide plate, thereby adjusting the tilt angle of the jig frame and facilitating workers to tie rebars at different angles.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that the side end of the binding jig is fixed in a fixed position by bolts and clamps, which results in the binding jig only being able to maintain a fixed angle, and the same set of jigs can only be used for a single specification of track slab, thus limiting the versatility of the jig. The overall idea is as follows:
[0026] To address the problems existing in the prior art, this utility model provides a multi-angle positioning clamp for a rebar tying jig, including a jig frame 11 and two support plates 12. Both sides of the jig frame 11 are provided with insertion slots. By moving the two support plates 12, the jig frame 11 is fixed inside the support plates 12 through the insertion plates 16.
[0027] Four positioning components are provided, each of which is located on the side of the support plate 12. Each positioning component includes an insert plate 16 and a guide plate 17. Two card holders 24 are fixedly installed on the side of each insert plate 16. A connecting strip 23 is rotatably installed inside each card holder 24. The connecting strip 23 slides at both ends of the adjusting frame 18 by driving the transmission plate 22. At the same time, the transmission plate 22 pushes the end of the connecting strip 23, causing the connecting strip 23 to rotate inside the card holder 24. This pushes one end of the insert plate 16, causing the insert plate 16 to rotate at the side end of the guide plate 17, thereby adjusting the tilt angle of the fixture frame 11.
[0028] Two adjustment frames 18 are fixedly installed on the side end of each support plate 12. A knob 19 is rotatably installed on the outside of each adjustment frame 18. A bevel gear is installed at the end of the knob 19 and connected to two threaded push rods 21. Rotating the knob 19 causes the threaded push rods 21 to rotate inside the adjustment frame 18.
[0029] Each adjustment frame 18 has a threaded push rod 21 rotatably mounted on both sides, and a transmission plate 22 rotatably mounted on the surface of each threaded push rod 21. The thread helix angle of each threaded push rod 21 and the transmission plate 22 is less than the friction angle. The rotating threaded push rod 21 rotates inside the transmission plate 22 at the same time, generating a thrust on the transmission plate 22, causing the transmission plate 22 to slide at both ends of the adjustment frame 18. At the same time, the threaded push rod 21 stops rotating, and the threaded push rod 21 and the transmission plate 22 can lock themselves.
[0030] The end of each connecting bar 23 is rotatably connected to the top of the transmission plate 22. Moving the transmission plate 22 generates a thrust on the connecting bar 23, and the connecting bar 23 synchronously pushes one end of the insert plate 16, causing the insert plate 16 to tilt synchronously. At the same time, the insert plate 16 is pushed to move synchronously in the same direction, which can adjust the distance between the two insert plates 16 and position and install different specifications of fixture frames 11.
[0031] Each support plate 12 is equipped with a drive assembly at its side end. Each drive assembly includes a fixed column 13, a drive wheel 14, and a rotating shaft 15. One end of the rotating shaft 15 is connected to a motor. The foundation is fixed by the jig frame 11, and the steel frame is tied to the surface of the jig frame 11. The jig frame 11 supports the tied subway track slab, ensuring the stability and accuracy of the steel reinforcement installation. The rotating shaft 15 is connected to the drive wheel 14, which drives the fixed column 13 to rotate. At the same time, the fixed column 13 drives the support plate 12 to rotate.
[0032] One end of each drive wheel 14 is rotatably connected to the frame, and each fixed column 13 is abutted against the surface of the rotating shaft 15. The end of the fixed column 13 is connected to the fixed plate. The fixed column 13 can drive the support plate 12 to rotate, while allowing the jig frame 11 to be adjusted, making it easier to tie steel bars at different angles. At the same time, since the rotating shaft 15 is directly connected to the output shaft of the motor, the rotation of the motor drives the support plate 12 to rotate on the side of the fixed plate, which is more labor-saving.
[0033] Working principle:
[0034] The first step involves inserting the insert plate 16 into the socket on the support plate 12 to initially fix the fixture frame 11 inside the support plate 12. When it is necessary to adjust the tilt angle of the fixture frame 11, rotate the knob 19 on the outside of the adjustment frame 18 at the side end of each support plate 12. Since the bevel gear installed at the end of the knob 19 is connected to two threaded push rods 21, the rotation of the knob 19 will drive the threaded push rods 21 to rotate inside the adjustment frame 18. Because the thread helix angle of the threaded push rod 21 and the transmission plate 22 is less than the friction angle, when the threaded push rod 21 rotates, it will generate a thrust on the transmission plate 22, causing the transmission plate 22 to slide at both ends of the adjustment frame 18. When the threaded push rod 21 stops rotating, the threaded push rod 21 and the transmission plate 22 can lock their positions automatically.
[0035] In the second step, during the movement of the transmission plate 22, a thrust is generated on the connecting bar 23 rotatably connected to its top. The connecting bar 23 rotates inside the card holder 24, which is fixedly installed on the side of the insert plate 16. When the connecting bar 23 rotates, it generates a thrust on one end of the insert plate 16, causing the insert plate 16 to rotate on the side of the guide plate 17, thereby adjusting the tilt angle of the jig frame 11 and synchronously pushing the transmission plate 22 to move in the same direction. The distance between the two insert plates 16 can be adjusted to meet the positioning and installation requirements of jig frames 11 of different specifications.
[0036] The jig frame 11 is fixed in place, and the steel frame is tied to its surface to support the tied subway track slab, ensuring the stability and accuracy of the rebar installation. At this point, the drive assembly at the side end of the support plate 12 begins operation. One end of the rotating shaft 15 is connected to a motor. After the motor starts, it drives the rotating shaft 15 to rotate. The rotating shaft 15 connects to the drive wheel 14, and when the drive wheel 14 rotates, it drives the fixed column 13. The fixed column 13 then drives the support plate 12 to rotate, thereby adjusting the direction of the jig frame 11, making it easier for workers to tie rebar at different angles. Because the rotating shaft 15 is directly connected to the motor output shaft, the rotation of the motor drives the support plate 12 to rotate at the side end of the fixed plate, which is more labor-saving compared to manual operation.
[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
