[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-8, the present invention provides a technical solution: a flexible steel cage traction machine, including a frame. A chain transmission mechanism 1 for transmitting the steel cage 4 and a traction support mechanism 23 are provided on the frame. And a steel cage guiding component 3 parallel to the transmission direction of the chain transmission mechanism is provided on one side of the frame. The chain transmission mechanism and the traction support mechanism are relatively parallel. A traction moving component 2 for traction of the steel cage is provided on the traction support mechanism. A clamping component 7 is arranged above the traction moving component. The clamping component is used for clamping the stirrups 4-1 of the steel cage.

[0027] The frame includes a transverse bracket and a longitudinal bracket 22. A first slide rail and a first rack are provided on the longitudinal bracket. The chain transmission mechanism itself is not equipped with a power source. The first driving motor drives the first transmission gear to engage with the first rack for meshing movement, thereby driving the chain transmission mechanism to slide to different positions on the first slide rail, so as to meet the requirements of different steel cage specifications. The traction support mechanism is driven by the second driving motor to drive the second transmission gear to engage with the first rack for meshing movement, thereby driving the traction support mechanism to slide on the first slide rail.

[0028] A second slide rail and a second rack are provided on the traction support mechanism. The traction moving component is driven by a third driving motor 2-10 to drive the third transmission gear to engage with the second rack for meshing movement, thereby driving the traction moving component to slide on the second slide rail. The sliding traction moving component traction the steel cage to be transmitted through the chain transmission mechanism.

[0029] The traction moving component mainly clamps the stirrups 4-1 and controls the moving distance of the steel cage 4 by driving the third driving motor. There are 2 clamping points on each traction moving component 2. At the same time, the two clamping components are at a fixed position, and one can be driven by a hook claw driving motor 2-3 to be adjusted up and down on the guide rail 19 to meet the steel cage 4 of different heights. At the same time, the whole traction moving component can be rotated by 90° to realize the free movement of the traction mechanism at the bottom of the steel cage 4 without affecting the feeding and transfer of the steel cage 4. The steel cage guiding component 3 on one side of the frame can effectively ensure that the steel cage 4 walks in a straight line in the forward direction without deviation. The top of the traction moving component is provided with a steel cage. The traction moving component includes a support seat 6 slidably connected to the traction support mechanism. One side of the top of the support seat is provided with a rotation fulcrum 2-6. A connecting plate 5 is movably installed on one side of the rotation fulcrum. One side of the support seat is hinged with a turning cylinder 2-5. The output end of the turning cylinder is rotatably connected to the connecting plate, with the ability of semi-automatic or full-automatic production in cooperation with other automatic welding and feeding equipment.

[0030] A connecting rod 2-4 is rotatably arranged between the connecting plate and the support base. A claw driving motor is arranged on one side of the connecting plate. A lead screw 18 is arranged at the output end of the claw driving motor. A nut 21 is sleeved on the surface of the lead screw. The number of the chain transmission mechanisms 1 and the traction support mechanisms 18 is two groups each. Therefore, the traction moving components are also two groups, which can make the traction and grasping more stable and efficient. A one-way check component 2-9 is arranged at one end of the support base away from the connecting plate. The head claw of the one-way check component can be used to push the stirrup of the steel cage to continue moving forward for blanking or transferring to the next station. When the claw cylinder acts, the claw clamps or loosens the stirrup under the action of the guide groove. After the claw clamps in place, the third driving motor rotates to drive the traction moving component and the first row of stirrups and longitudinal bars clamped to move a certain distance. After moving in place, the welding or bundling of the second row of stirrups of the steel cage can be carried out. At the same time, the traction moving component realizes anti-side fall through the connecting rod 2-4 when moving. The clamping component 7 includes claw cylinders 2-7 arranged near the top and bottom of the connecting plate. Guide limit blocks 11 are arranged on the telescopic end guide rods of the claw cylinders. Upper claws 2-2 and lower claws 2-1 are respectively arranged on the inner sides of the guide limit blocks 11 near the top and bottom of the connecting plate. Guide grooves 2-8 are respectively formed on the surfaces of the connecting plate corresponding to the upper claws and the lower claws. Rollers 12 are movably installed inside the guide grooves 2-8. The rollers are respectively connected to the corresponding upper claws and lower claws. The guide grooves are divided into straight line segments and inclined line segments, which can enable the claws to move left and right inside the guide limit blocks 11 to realize real-time adjustment of the opening degree of the claws. A guide rail is arranged on the surface of the connecting plate on one side of the upper claw. The nut is connected to the claw cylinder at the upper claw. The lead screw 18 can be driven to rotate by the claw driving motor 2-3. At the same time, the lead screw drives the nut to move, and then drives the upper claw to move up and down for adjustment to meet the clamping requirements of steel cages at different heights.

[0031] Working principle: After the production line is started, two chain transmission mechanisms 1 and two traction support mechanisms move to positions suitable for the specifications of the steel cage under the drive of the first drive motor and the second drive motor respectively and stop. The upper claw 2-2 drives the screw rod to rotate through the claw drive motor, so as to slide on the clamping guide rail to the corresponding position suitable for the specifications of the steel cage 4. The two traction moving components 2 both stop at one position waiting for the traction instruction. When the first row of stirrups and longitudinal bars of the steel cage are welded or tied and reach the traction designated position, a traction instruction is issued. After receiving the instruction, the two traction moving components 2 move to contact the first row of stirrups. The lower claw 2-1 is connected to the cylinder 2-7. At the same time, an inclined guide groove 2-8 is provided on the mounting plate, and there are rollers on the guide groove connected to the claw. Therefore, when the cylinder acts, the claw clamps or loosens the stirrup 4-1 under the action of the guide groove. The upper claw 2-2 is the same. After the claw clamps in place, the third drive motor 2-10 rotates to drive the traction moving component and the clamped first row of stirrups and longitudinal bars to move a certain distance on the traction support mechanism 23. After moving in place, the welding or tying of the second row of stirrups of the steel cage can be carried out. At the same time, the traction moving component realizes anti-tipping through the connecting rod 2-4 when moving. In this way, all the stirrups and longitudinal bars are welded or tied together in sequence to form a steel cage. Then the claw loosens the steel cage, and the rotating cylinder 2-5 contracts to rotate the clamping assembly around the fulcrum 2-6 with the connecting plate, so as to rotate by 90°. It overlaps with the support seat. Therefore, the traction moving component can move freely at the bottom of the steel cage. And a one-way check assembly is provided at the tail of the traction moving component. The claw at the head of the check assembly 2-9 is used to push the stirrup 4-1 of the steel cage to continue to move forward for blanking or transferring to the next station.
