Description

Technical Field

[0001] The invention relates to a steel cage processing device. Background Art

[0002] Most of the existing small steel cages are made by steel cage rolling welding machines. After the welder completes the welding of the steel cage frame on the welding table, it is placed on the steel cage rolling welding machine. The rolling welding machine drives the steel cage frame to roll through the power rollers on both sides, and the stirrups are wound onto the steel cage frame through the straightening machine.

[0003] The frame of a small steel cage is relatively light. When the steel cage is reinforced by a roll welder, the steel cage frame will jump relative to the power roller when rolling with the power roller, and the direct position of the steel cage frame and the roll welder cannot be ensured, which leads to uneven reinforcement of the steel cage frame, affecting the processing quality of the steel cage;

[0004] At the same time, during the process of hoop reinforcement, the steel cage near the middle position will be deformed under the action of its own gravity. Moreover, in order to ensure the tightness of the hoop reinforcement and the steel cage skeleton, excessive hoop reinforcement may sometimes occur during the hoop reinforcement process. The diameter of the steel cage skeleton deviates from the original diameter under the tension of the hoop reinforcement. During the construction process, it is sometimes necessary to use a longer steel cage. The steel cage processed using the steel bars at the construction site is generally 9 meters long. In actual use, multiple steel cages need to be overlapped together. The diameter deviation caused by the completion of the steel cage processing will affect the normal overlap between the steel cages, resulting in poor stability and weighing capacity at the connection. Summary of the invention

[0005] The present invention proposes a steel cage processing equipment, which is used to fix and support the steel cage frame during the process of hoop reinforcement of the steel cage frame, to prevent the steel cage frame from being detached from the processing equipment during the rolling process, and to prevent the steel cage frame from having an actual diameter deviating from a predetermined diameter due to excessive hoop reinforcement during the hoop reinforcement process, which affects the lap joint of the steel cage.

[0006] The technical solution of the present invention is achieved as follows: a steel cage processing equipment, comprising a base for carrying a steel cage skeleton and a straightening and winding assembly for winding the steel cage skeleton, the base and the straightening and winding assembly maintain a relatively uniform motion state, the base is provided with two power rollers in parallel, the two power rollers are connected to a power source, the base is provided with a support assembly for further supporting the steel cage skeleton, the support assembly comprises a support rod, a connecting shaft and a guide support frame body, the support rods are two, the two support rods are installed on both sides of the base and are perpendicular to the base, the two support rods are connected by the connecting shaft, the guide support frame body comprises a sleeve at its center position and adapted to the connecting shaft and at least three connecting rods uniformly circumferentially arranged on the outer wall of the sleeve, the end of each connecting rod in contact with the steel cage skeleton is fixed with an arc-shaped positioning plate, the sleeve is sleeved outside the connecting shaft and forms a structure that can rotate around the connecting shaft;

[0007] The straightening and winding assembly includes a conductor, a shell and two groups of straightening turntables. The conductor is a straightening machine used to straighten stirrups. The shell is provided with a wire inlet and a wire outlet. The shell is provided with a mounting plate for mounting the two groups of straightening turntables. The centers of the two groups of straightening turntables are respectively located on two parallel lines. The stirrups pass between the two groups of adjustment turntables in the shell and contact the side walls of each straightening turntable.

[0008] The technical effect of this scheme is as follows: when the steel cage skeleton is being reinforced, the welded steel cage skeleton is placed on the two power rollers of the base, and then the connecting shaft and the guide support frame are sleeved in the steel cage skeleton, and the end of the connecting shaft is connected to the two support rods. The length of the connecting rod is directly adjusted according to the preset of the steel cage skeleton, so that the positioning plate at the free end of the connecting rod fits with the inner wall of the steel cage skeleton, and the steel cage is supported inside the steel cage skeleton. The connecting rod can rotate around the connecting shaft through the sleeve. During the reinforcement process of the steel cage skeleton, the power roller drives the steel cage skeleton to roll, and the guide support frame rolls with the steel cage skeleton in the steel cage skeleton. The guide support frame maintains a relatively fixed positional relationship with the steel cage skeleton. The guide support frame can support the guide support frame of different diameters within a certain range, so as to prevent the steel cage skeleton from being separated from the power roller during the reinforcement process, and also prevent the steel cage skeleton from being subjected to excessive reinforcement during the reinforcement process. The actual processed diameter of the steel cage deviates from the preset diameter, which affects the overlap with other steel cages in the later stage;

[0009] The straightening machine is used to straighten the coiled stirrups when they are wound in front of the steel cage frame. The stirrups enter the shell from the wire inlet and pass through two sets of straightening turntables in the shell to finally be led out from the wire outlet to achieve straightening of the stirrups. The straightening machine further ensures the straightening effect of the stirrups.

[0010] On the basis of the above scheme, further improvements are made as follows: each of the connecting rods includes a first connecting rod in the shape of a round rod and a second connecting rod in a tubular structure, the second connecting rod is sleeved on the outside of the first connecting rod, a threaded connection structure is arranged between the inner wall of the second connecting rod and the outer wall of the first connecting rod, and a spring is arranged between the ends of the first connecting rod and the second connecting rod.

[0011] The technical effect of this solution is that the overall length of the first connecting rod and the second connecting rod can be adjusted by the thread set at the connection between them, and the setting of the spring prevents the first connecting rod and the second connecting rod from sliding relative to each other under the action of external forces other than human forces, so that the overall length of the connecting rod becomes loose when supporting the steel cage bracket, resulting in insufficient supporting force.

[0012] On the basis of the above technical solution, further improvements are made as follows: a plurality of connecting grooves matched with the sleeve are evenly arranged on the connecting shaft, the diameter of the connecting groove is smaller than the diameter of the connecting shaft, the guide support frame is installed on the connecting shaft through the connecting groove, and the interior of the sleeve is provided with a mounting groove along its circumference, a plurality of balls are embedded in the mounting groove, and each ball portion extends out of the mounting groove and contacts with the side wall of the connecting groove.

[0013] The technical effect of this scheme is: the sleeve contacts the side wall of the connecting groove through the ball bearing, and the friction generated when the guide support frame rotates relative to the connecting shaft through the sleeve is rolling friction, which reduces the friction force generated when the guide support frame rotates with the steel cage frame relative to the connecting shaft, prevents the guide support frame from blocking the rotation of the steel cage, and further increases the uniformity of the stirrups.

[0014] Based on the above solution, a further improvement is as follows: the side of the positioning plate forms an inclination angle toward the direction of the connecting axis.

[0015] The technical effect of this solution is that when the guide support frame supports the steel cage frame, it prevents the edge of the positioning plate from hooking with the steel cage frame, and also facilitates the separation of the completed steel cage and the guide support frame.

[0016] Based on the above solution, the two power rollers are connected by a transmission belt.

[0017] The technical effect of this solution is: by setting up a conveyor belt, the friction between the roller and the steel cage frame can be increased when the roller rotates relative to the steel cage frame, further preventing the steel cage frame from slipping during the rotation of the roller, increasing the stability of the steel cage winding, and further improving the quality of steel cage processing.

[0018] On the basis of the above scheme, further improvement is as follows: each of the adjusting dials is mounted on the mounting plate via a fixed shaft, forming a structure in which each of the adjusting dials rotates around the connecting shaft on the mounting plate.

[0019] The technical effect of this solution is that when the steel cage is in the process of stirruping, each adjusting dial rotates to straighten the stirrups and guides the straightened stirrups out of the outlet.

[0020] On the basis of the above scheme, further improvements are made as follows: a plurality of channel steel brackets are evenly arranged between the two power rollers, and the end surface of each channel steel bracket in contact with the steel cage skeleton is an arc surface structure.

[0021] The technical effect of this solution is: the bearing capacity of the steel cage skeleton can be increased by using multiple channel steel brackets, and the stability of the steel cage skeleton support can be increased by the outside of the steel cage.

[0022] On the basis of the above scheme, a further improvement is made as follows: the middle position of the upper end of the support rod is recessed downward to form a groove body, and the end of the connecting shaft is extended in the axial direction to have a block adapted to the groove body, and a detachable connection structure is set between the block and the groove body through bolts.

[0023] The technical effect of this solution is that after the steel cage is manufactured, the connecting shaft and the support rod are disassembled, so that the connecting shaft and the guide support frame on the connecting shaft can be easily taken out from the steel cage frame.
