Technical Field

[0001] This invention relates to the field of box girder bottom web manufacturing technology, specifically to a stirrup stripping mechanism. Background Technology

[0002] In the current field of highway box girder steel reinforcement cage production, stirrup stripping is an important and challenging process. Existing box girder bottom web stirrup stripping mechanisms have many defects, which seriously restrict the improvement of production efficiency and product quality, and increase equipment maintenance costs.

[0003] Currently, separating stirrups from the steel reinforcement cage structure is inconvenient, resulting in a significant reduction in the peeling effect. This can easily lead to stirrup deformation, or even problems such as residual stirrups and incomplete peeling, thus reducing the product qualification rate. Therefore, it is necessary to effectively solve the above-mentioned drawbacks and obtain good stirrup peeling efficiency and quality. In view of this, we propose a stirrup peeling mechanism. Summary of the Invention

Each peeling assembly includes a main frame of the mechanism that is detachably mounted on the base of the peeling mechanism, and two peeling units that are detachably mounted on the main frame of the mechanism via a slider mounting plate.

[0008] A power source is installed on the slider mounting plate to drive the peeling unit to move back and forth. The peeling unit is used to peel off the stirrups.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0033] A stirrup stripping mechanism, such as Figure 1 The structure shown includes a peeling mechanism base 1 for fixing to the ground, and also includes:

[0034] Two mirror-symmetrically positioned stripping components, such as Figure 1 and Figure 4 The structure shown includes a main frame 2 of the mechanism that is detachably mounted on the base 1 of the peeling mechanism, and two peeling units that are detachably mounted on the main frame 2 of the mechanism via a slider mounting plate 17.

[0035] In this embodiment, the stripping unit is as follows: Figure 2 and Figure 3 The structure shown includes a peeling unit comprising a telescopic arm body 6 disposed on the outside of a slider mounting plate 17, which is fixedly mounted as shown in the figure. Figure 1 On the main frame 2 of the mechanism shown, two linear rails 21 are installed on the corresponding side of the telescopic arm body 6 and the slider mounting plate 17. The slider body 20 is slidably installed on the two linear rails 21, and the slider body 20 is detachably installed on the slider mounting plate 17, that is, the telescopic arm body 6 with the linear rails 21 installed can be slid back and forth through the slider body 20.

[0036] It is important to note that, such as Figure 1 and Figure 2 As shown in the structure, a bolt-type roller needle bearing 4 is installed on the main frame 2 of the mechanism via a support bearing mounting seat 3. The bolt-type roller needle bearing 4 can support the telescopic arm body 6.

[0037] Specifically, to achieve its automated reciprocating movement, a rack 22 is fixedly installed on the telescopic arm body 6 between two linear tracks 21, such as... Figure 3 The structure shown has a transmission gear 25 meshing with the rack 22. It's important to note that because the telescopic arm body 6 is already fixed via the slider body 20, this transmission gear 25 is connected to the output shaft of the servo motor 18 mounted on the slider mounting plate 17. This ensures that the transmission gear 25 is always meshing with the rack 22, thus enabling the reciprocating movement of the telescopic arm body 6. Furthermore, to prevent derailment, as... Figure 3 At the positions shown, limit blocks 23 are installed at both ends of the telescopic arm body 6 to prevent the transmission gear 25 from derailing.

[0038] In order to improve the accuracy of the movement position, a servo motor 18 is installed on the slider mounting plate 17 as a power source. The output shaft of the servo motor 18 is coaxially connected with the transmission gear 25. At the same time, a reducer body 19 is installed on the slider mounting plate 17 through the reducer mounting plate 24. The reducer body 19 is used to install at the output shaft of the servo motor 18, which can maintain the stability of the movement and stop, and is conducive to improving accuracy.

[0039] like Figure 2 and Figure 3The structure shown has a cable chain body 5 mounted on the telescopic arm body 6, and one end of the cable chain body 5 is detachably mounted on the main frame 2 of the mechanism via a cable chain mounting plate 16. It should be noted that a first mounting seat 7 is mounted on one end of the telescopic arm body 6. A first three-axis cylinder 8 and a second three-axis cylinder 14 are detachably mounted on the first mounting seat 7. A second mounting seat 9 is mounted at the output shaft of the first three-axis cylinder 8. A finger cylinder 10 is mounted on the second mounting seat 9. A hoop clamp 15 is mounted on the finger cylinder 10. In addition, a sensor seat 13 is mounted at the output shaft of the second three-axis cylinder 14. A mounting base 11 is provided on the sensor seat 13. An infrared photoelectric switch 12 is detachably mounted on the mounting base 11.

[0040] It should be noted that the working principle of the stirrup stripping mechanism of the present invention is as follows: First, before operation, the base 1 of the stripping mechanism is fixed to the ground with expansion bolts. During operation, as follows... Figure 4 The mirror-symmetric structure shown can drive the telescopic arm body 6 to move through four sets of servo motors 18, reducer body 19, transmission gear 25, and rack 22; at the same time, the second three-axis cylinder 14 can drive the sensor seat 13, mounting base 11, and infrared photoelectric switch 12 to extend. When the telescopic arm body 6 moves continuously, when any set of infrared photoelectric switches 12 senses the stirrup, the first three-axis cylinder 8 will drive the second mounting seat 9, finger cylinder 10, and stirrup gripper 15 to extend.

[0041] Using the mounting base 11 and stirrup clamps 15, the horizontal movement of one set of stirrups can be restricted. The working principle of the other three sets of telescopic arm bodies 6 is the same. After the four sets of telescopic arm bodies 6 sense the stirrups and restrict their horizontal movement, the foremost set of telescopic arm bodies 6 is used as the reference, and the other three sets of telescopic arm bodies 6 move forward to align with it. At the current position, the four sets of finger cylinders 10 clamp inward, and the stirrups are clamped by the mounting base 11 and stirrup clamps 15. At this time, the four sets of telescopic arm bodies 6 move forward at the same time, and stop after moving to the handover position, waiting for handover.

[0042] During the handover, the four sets of finger cylinders 10 are first released. Then, the first three-axis cylinder 8 will drive the gripper cylinder mounting seat, finger cylinders 10, and hoop gripper 15 to move in the opposite direction. Then, the telescopic arm body 6 moves forward again by 3-5cm. After the hoop is removed from the range of the mounting base 11, the second three-axis cylinder 14 will drive the induction seat 13, mounting base 11, and infrared photoelectric switch 12 to move in the opposite direction.

[0043] After the handover is completed, the four telescopic arm bodies 6 move simultaneously to disengage from the handover. The second and third axis cylinders 14 drive the induction seat 13, mounting base 11, and infrared photoelectric switch 12 to extend, starting the next cycle. In this embodiment, the support bearing mounting seat 3 and the bolt-type roller needle bearing 4 play a reinforcing role. When the telescopic arm body 6 extends too far forward, it can maintain the horizontal movement of the telescopic arm body 6, reducing the load on the servo motor 18, reducer body 19, transmission gear 25, and rack 22 when the front end of the telescopic arm body 6 droops. This avoids damage to the telescopic arm body 6 during long-term reciprocating motion and helps ensure stable operation of the equipment. It should be noted that the two mirror-symmetrically arranged peeling components can provide four peeling units for peeling the stirrups, which helps improve the efficiency and quality of stirrup peeling, avoids the problems of deformation, residue, or incomplete peeling during stirrup peeling, and helps improve the product qualification rate.

[0044] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0045] Furthermore, if the embodiments of the present invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description; therefore, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within the present invention.
