Technical Field

[0001] The utility model relates to an auxiliary steel cage spiral stirrup binding device, belonging to the technical field of building construction auxiliary equipment. Background Art

[0002] The tensile strength of concrete is low and needs to be compensated by steel bars. Therefore, a large number of steel cages are needed in construction. The steel cage mainly includes two types of longitudinal bars and stirrups wrapped around the periphery of the longitudinal bars. Manually wrapping the stirrups around the periphery of the longitudinal bars in a spiral manner has certain safety hazards and high labor intensity.

However, when the stirrups are wrapped around the outer periphery of the longitudinal reinforcement to form a steel cage and need to be removed, the belt connecting the power device and the rotating shaft needs to be manually pried and deformed before it can be removed, causing inconvenience.

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figure 1 shown.

[0022] The present invention provides an auxiliary steel cage spiral stirrup binding device, comprising:

[0023] The motor support 4 supports the motor 2 and is provided with a sliding groove 5. The motor 2 can only be slidably installed in the sliding groove 5. The base plate of the motor 2 housing is clamped in the sliding groove 5 on the motor support 4 and can only slide.

[0024] A rack is provided on the motor support 4 located on the side of the sliding groove 5, and a rotating rod 3 is rotatably installed on the motor 2 housing. The rotating rod 3 is provided with rotating teeth that mesh with the rack on the motor support 4. By rotating the rotating rod 3, the motor 2 can slide in the sliding groove 5.

[0025] The rotating output shaft of the motor 2 is installed with a driving gear 6 through a flat key. When the motor 2 slides axially, it is disengaged from the driving gear 6 through the flat key. A power rod is axially fixed to the driving gear 6. The power rod is fixed to the internal ring reinforcement of the longitudinal reinforcement 1 of the steel cage. The motor 2 drives the driving gear 6 to rotate, and the driving gear 6 drives the longitudinal reinforcement 1 to rotate; it also includes a support seat 11 spaced apart from the motor support 4, and the support seat 11 is a plurality of spaced distributions to support the longitudinal reinforcement 1 at intervals for rotation. There are bearings or balls on the support seat 11 so that the longitudinal reinforcement 1 can rotate thereon.

[0026] The driving gear 6 is radially meshed with a pinion 7; it also includes a pulley base 10 spaced apart at the side of the motor support 4, the pinion 7 is rotatably mounted on the pulley base 10, a rotatable driving wheel 9 is mounted on the pulley base 10, and the driving wheels 9 are multiple and spaced apart, and a steel chain 8 is hung on the multiple distributed driving wheels 9, and the steel chain 8 rotates on the driving wheel 9, and the driving wheel 9 at the end of the pulley base 10 is fixedly connected to a helical gear shaft, and the helical teeth of the helical gear shaft are meshed with the pinion 7. The rotation of the driving gear 6 drives the pinion 7 to rotate, and the pinion 7 transmits the rotation to the driving wheel 9 through the meshing reversing of the helical gear shaft to drive the steel chain 8 to rotate.

[0027] The stirrups are installed on the rotating steel chain 8 and axially displaced along the rotation axis of the driving gear 6. The longitudinal reinforcement 1 of the steel cage is driven to rotate by the driving gear 6, so that the stirrups can be spirally wrapped around the periphery of the longitudinal reinforcement to form a steel cage. When the steel cage is formed, the motor 2 slides in the sliding groove 5 on the motor support 4. When the motor 2 slides axially, it is disengaged from the driving gear 6 through the flat key, and the steel cage is disengaged from the support seat 11 with the driving gear 6. The present application axially displaces stirrups with lighter weight and does not use belts for driving. This solves the problem that when the steel cage needs to be removed after it is formed, the belt connecting the power device and the rotating shaft needs to be manually pried and deformed before it can be removed, resulting in inconvenience in operation.

[0028] During operation, the motor support 4, the support seat 11, and the pulley base 10 are fixed, and the motor 2 on the motor support 4 drives the driving gear 6 to rotate the longitudinal reinforcement 1. At the same time, the driving gear 6 drives the steel chain 8 to rotate on the driving wheel 9, and the rotation axis of the longitudinal reinforcement 1 and the rotation axis of the steel chain 8 are perpendicular to each other.
