Description

Technical Field

[0001] This utility model relates to the field of hydraulic platform climbing technology for construction machinery, specifically an automatic reversing box for a climbing mechanism. Background Technology

[0002] In high-rise building construction, climbing rails are often used to transport trolley platforms or other loads upwards along the wall. A reversing box connects both the climbing rail and the formwork, controlling the lifting of either the climbing rail or the formwork. Hydraulic cylinders enable mutual climbing between the formwork and the climbing rail, allowing the self-climbing formwork to steadily ascend. The climbing rail is installed perpendicular to the ground, with ladders welded to its surface and evenly spaced along its height.

[0003] Currently, the hydraulic platform climbing reversing box requires the operator to adjust the direction of the pawl and then start the cylinder. With the reversing handle pointing downwards, the lower bearing surface of the pawl presses against the top of the ladder rung, and the climbing formwork moves relative to the climbing rail. By having the climbing rail and climbing formwork alternately attached to the wall and lifting each other, the climbing formwork can be lifted layer by layer along the pre-reserved climbing cone on the wall.

[0004] However, in the existing technology, the direction of the climbing claw is mainly controlled by rotating the handle or pushing rod to control the direction of the restoring force. This control method not only makes the structure more complex and inconvenient to maintain, but also makes the handle or pushing rod prone to loosening under large forces, which has a significant impact on the safety of climbing. Therefore, it has certain shortcomings. Utility Model Content

[0005] The present invention aims to provide an automatic reversing box for a climbing mechanism. The reversing of this reversing box is achieved by intelligent reversing through a stepper motor controlled by a PLC, so as to solve the problem that the existing reversing boxes require manual reversing and have low safety performance, and improve the shortcomings of the climbing automatic reversing box.

[0006] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: an automatic reversing box for a climbing mechanism includes a lower cover plate and an upper cover plate. Multiple vertically arranged wall panels are fixedly installed between the lower cover plate and the upper cover plate. A climbing head shaft is rotatably installed between the wall panels. A hammer-shaped climbing head is fixedly installed on the climbing head shaft. One end of the climbing head shaft is fixedly connected to the output shaft of a stepper motor. The stepper motor is fixed on the outer wall of the wall panel. The conical end of the hammer-shaped climbing head is hinged to one end of a spring buffer. The other end of the spring buffer is hinged to the wall panel through a spring buffer seat plate.

[0007] The climbing head shaft is fixedly connected to the output shaft of the stepper motor via a coupling, and transmits torque.

[0008] The hammer-shaped climbing head is connected to the climbing head shaft via a flat key and transmits torque.

[0009] The hammer-shaped climbing head includes a shaft hole that mates with the climbing head shaft, and the tapered end of the hammer-shaped climbing head is provided with a hinge hole for connecting a spring buffer.

[0010] The wall panel is provided with shaft holes for mating with the climbing head shaft.

[0011] The bottom end of the upper cover plate is fixed with an upper crossbeam, which is used to contact and limit the upper end face of the hammer-shaped climbing head; the upper bearing surface of the hammer-shaped climbing head is used to abut against the lower end face of the ladder rung.

[0012] The top of the lower cover plate is fixed with a lower crossbeam, which is used to contact and limit the lower end face of the hammer-shaped climbing head; the lower bearing surface of the hammer-shaped climbing head is used to abut against the upper end face of the ladder rung.

[0013] The stepper motor is connected to the PLC controller, which controls the forward and reverse rotation of the stepper motor.

[0014] The present invention has the following beneficial effects:

[0015] 1. This utility model has a simple structure, which is easy to inspect and maintain. The climbing head shaft is connected to the stepper motor, which does not require manual operation. The stepper motor is controlled by PLC, which can be easily controlled intelligently. It can be inspected with a camera. Because it is unmanned, it has a high degree of safety.

[0016] 2. The tail of the climbing claw in this utility model is directly connected to the spring buffer, eliminating the need for transmission of elastic force through a shaft, thus improving reliability; the spring buffer uses a compression spring, which, unlike conventional tension springs, is prone to breakage, further enhancing reliability.

[0017] 3. The climbing claw of this utility model adopts a reaction beam to balance the climbing claw head, which is more reliable than the conventional reversing box wall or pin to balance the climbing claw head. Attached Figure Description

[0027] Hinge hole 201, shaft hole 202. Detailed Implementation

[0028] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0029] Example 1:

[0030] See Figure 1-7 An automatic reversing box for a climbing mechanism includes a lower cover plate 10 and an upper cover plate 11. Multiple vertically arranged wall panels 9 are fixedly installed between the lower cover plate 10 and the upper cover plate 11. A climbing head shaft 4 is rotatably mounted between the wall panels 9. A hammer-shaped climbing head 2 is fixedly mounted on the climbing head shaft 4. One end of the climbing head shaft 4 is fixedly connected to the output shaft of a stepper motor 1. The stepper motor 1 is fixed to the outer wall of the wall panel 9. The conical end of the hammer-shaped climbing head 2 is hinged to one end of a spring buffer 3. The other end of the spring buffer 3 is hinged to the wall panel 9 via a spring buffer seat plate 14. The reversing of this box is intelligently achieved by controlling the stepper motor with a PLC, solving the problem of existing reversing boxes requiring manual reversing and having low safety performance, thus improving the shortcomings of automatic reversing boxes for climbing. In practical use, the PLC controls the stepper motor for automatic reversing, and then the stepper motor 1 controls the hammer-shaped climbing head 2. The reversing of the hammer-shaped climbing head 2 achieves the switching between climbing rails and climbing formwork.

[0031] Furthermore, the climbing head shaft 4 is fixedly connected to the output shaft of the stepper motor 1 via a coupling, and transmits torque. Through the aforementioned coupling connection, it is ensured that the stepper motor 1 can drive the climbing head shaft 4 to rotate synchronously, thereby synchronously driving the rotation and reversal of the hammer-shaped climbing head 2 via the climbing head shaft 4.

[0032] Furthermore, the hammer-shaped climbing head 2 is connected to the climbing head shaft 4 via a flat key, and transmits torque. This flat key connection ensures that the rotation of the climbing head shaft 4 can drive the hammer-shaped climbing head 2 to rotate, thereby achieving reversal through the rotation of the hammer-shaped climbing head 2.

[0033] Furthermore, the hammer-shaped climbing head 2 includes a shaft hole 202, which cooperates with the climbing head shaft 4. The tapered end of the hammer-shaped climbing head 2 is provided with a hinge hole 201 for connecting the spring buffer 3. Through the above-mentioned hammer-shaped climbing head 2, it can be driven to rotate by the climbing head shaft 4, and the spring buffer 3 can lock the hammer-shaped climbing head 2 in the state after reversing direction.

[0034] Furthermore, the wall panel 9 is provided with a shaft hole for cooperating with the climbing head shaft 4. The shaft hole ensures that the climbing head shaft 4 can rotate normally thereafter.

[0035] Furthermore, an upper crossbeam 7 is fixed to the bottom end of the upper cover plate 11. The upper crossbeam 7 is used to contact and limit the upper end face of the hammer-shaped climbing head 2; the upper bearing surface 12 of the hammer-shaped climbing head 2 is used to abut against the lower end face of the step 6. The upper crossbeam 7 can limit the upper limit position of the hammer-shaped climbing head 2.

[0036] Furthermore, a lower crossbeam 8 is fixed to the top of the lower cover plate 10. The lower crossbeam 8 is used to contact and limit the lower end face of the hammer-shaped climbing head 2; the lower bearing surface 13 of the hammer-shaped climbing head 2 is used to abut against the upper end face of the step 6. The lower crossbeam 8 can limit the lower limit position of the hammer-shaped climbing head 2.

[0037] Furthermore, the stepper motor 1 is connected to a PLC controller, which controls the forward and reverse rotation of the stepper motor 1. The PLC controller enables automatic control of the stepper motor 1, thereby achieving its reversing operation.

[0038] Example 2:

[0039] See Figure 5-7 An operating method for the automatic reversing box of a climbing mechanism:

[0040] When the climbing rail needs to be raised, the stepper motor 1 is controlled by the PLC controller to move counterclockwise. The spring of the spring buffer 3 is compressed. After passing the balance middle position, the spring is released. The stepper motor 1 drives the climbing head shaft 4 to rotate at the same time. The rotation of the climbing head shaft 4 causes the upper bearing surface 12 of the hammer-shaped climbing head 2 to press against the bottom of the ladder rung 6. The other end of the hammer-shaped climbing head 2 presses against the bottom of the upper crossbeam 7. The hydraulic cylinder works, thereby causing the climbing rail to move upward.

[0041] When the climbing formwork frame needs to be lifted, the stepper motor 1 is controlled to move clockwise by the PLC controller. The spring of the spring buffer 3 is compressed. After passing the balance middle position, the spring is released. The climbing head shaft 4 rotates so that the lower bearing surface of the hammer-shaped climbing head 2 abuts against the top of the ladder rung 6. The other end of the hammer-shaped climbing head 2 abuts against the lower crossbeam 8. The hydraulic cylinder works, and the reversing box climbs along the climbing rail, thereby lifting the climbing formwork frame.
