Description

Technical Field

[0001] This utility model relates to a tensioning device for reinforcing rings of steel cages, belonging to the field of steel cage production technology. Background Technology

[0002] A rebar cage welding workstation is a device that integrally processes and forms a rebar cage. For example, patent application number 202410401012.9 discloses a rebar cage welding workstation. In practice, workers manually install reinforcing rings on a roll welding machine, and then the roll welding machine automatically welds the main reinforcing bars to the reinforcing rings to form a rebar skeleton. After the rebar skeleton is welded, the roll welding machine releases the rebar skeleton and transfers it to one side of a rebar winding machine along a track via a moving component. Then, a lifting component abuts against and detaches the rebar skeleton from the moving component, and the moving component resets along the track. The rebar winding machine automatically performs winding welding on the rebar skeleton on the lifting component, while the roll welding machine restarts the welding of the reinforcing rings and main reinforcing bars.

[0003] Current technology is not comprehensive and has the following drawbacks: 1. Manually installing the reinforcing rings on the welding machine requires an additional 2-3 workers specifically responsible for positioning and fixing the reinforcing rings, making fully automated production impossible. 2. Manual placement can easily lead to the reinforcing rings not being welded perpendicularly to the main reinforcement bars, affecting the overall roundness of the rebar cage. 3. In high-temperature environments, workers need to frequently enter and exit the equipment area, increasing the risk of operational errors and mechanical injury accidents.

[0004] To solve one of the above problems, there is an urgent need for a steel cage reinforcing ring tensioning device. Utility Model Content

[0005] Based on the shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to make the positioning strut play a role in temporarily positioning and supporting the reinforcing ring, so as to cooperate with the welding robot to weld multiple reinforcing rings sequentially along the axial direction of the steel cage and improve efficiency. To this end, a steel cage reinforcing ring tensioning device is provided.

[0006] The reinforcing cage tensioning device of this utility model is characterized in that: it includes a central support member, and multiple sets of positioning struts with the same length direction are arranged on the outer side of the central support member. The multiple sets of positioning struts are arranged around the center line of the central support member and the included angle between adjacent struts is the same. A spreading mechanism that drives the positioning struts to move closer to or away from the central support member is installed on the central support member. A transmission shaft driver is installed at one end of the central support member. The transmission shaft driver is connected to the spreading mechanism through a transmission shaft.

[0007] When the drive shaft driver is activated, the drive shaft is pulled backward. The drive shaft drives the positioning struts away from the central support through the spreading mechanism. Multiple sets of positioning struts are arranged around the center line of the central support until the positioning struts contact the inner ring of the reinforcing ring, providing temporary positioning and support for the reinforcing ring. In conjunction with the welding robot, multiple reinforcing rings can be welded sequentially along the axial direction of the steel cage, improving efficiency. After the reinforcing rings are welded to the steel cage, the drive shaft driver is activated again to push the drive shaft forward. The drive shaft drives the positioning struts closer to the central support through the spreading mechanism. The positioning struts disengage from the reinforcing rings, returning to the initial state.

[0008] In any of the above embodiments, it is preferred that the positioning support rods are provided in four sets, namely the first positioning support rod, the second positioning support rod, the third positioning support rod and the fourth positioning support rod. The first positioning support rod, the second positioning support rod, the third positioning support rod and the fourth positioning support rod are all arranged around the center line of the central support member and the included angle between adjacent ones is the same. Corresponding to the four sets of positioning support rods, there are four sets of drive shafts, namely the first drive shaft, the second drive shaft, the third drive shaft and the fourth drive shaft. The four sets of positioning support rods correspond one-to-one with the four sets of drive shafts.

[0009] Each set of positioning struts uses an independent drive shaft for transmission, ensuring transmission stability and extending its service life.

[0010] In any of the above embodiments, it is preferred that the first positioning support rod is connected to the central support member by multiple sets of spreading mechanisms. The spreading mechanism includes a first fixed seat and a second fixed seat installed on the outer wall of the central support member. The first fixed seat has a sliding sleeve A that slides in cooperation with the first drive shaft, and the second fixed seat has a sliding sleeve B that slides in cooperation with the first drive shaft. A main drive rod is hinged to the first fixed seat, and the other end of the main drive rod is hinged to the first positioning support rod. A connecting rod hinge seat is installed on the first drive shaft between the first fixed seat and the second fixed seat. A driving connecting rod is hinged to the connecting rod hinge seat, and the other end of the driving connecting rod is hinged to the end of the main drive rod near the first fixed seat.

[0011] When the drive shaft driver is activated, the drive shaft is pulled backward, and the drive link hinged to the connecting rod hinge seat moves closer to the first fixed seat. The drive link causes the angle between the main drive rod and the central support to increase, and the end of the main drive rod away from the central support moves away from the central support, thereby driving the positioning support rod away from the central support. Multiple sets of positioning support rods are arranged around the center line of the central support until the positioning support rod contacts the inner ring of the reinforcing ring, which provides temporary positioning and support for the reinforcing ring.

[0012] The drive shaft driver is activated to push the drive shaft forward. The drive link, which is hinged to the connecting rod hinge seat, moves closer to the second fixed seat. The drive link causes the included angle between the main drive rod and the central support to decrease, thus completing the closing of the opening mechanism.

[0013] In any of the above embodiments, it is preferred that the connecting rod hinge seat is rotatably mounted with a traveling roller that can travel linearly along the outer wall of the central support member, ensuring the stability of the movement.

[0014] In any of the above embodiments, it is preferred that the first positioning support rod includes a first rod body and a second rod body that are parallel to each other, and the first rod body and the second rod body are fixed together by a connecting plate. The connecting plate is provided with a secondary hinge seat that is hinged to the main drive rod.

[0015] In any of the above solutions, it is preferred that the first positioning support rod, the second positioning support rod, the third positioning support rod and the fourth positioning support rod are respectively provided with six sets of opening mechanisms.

[0016] In any of the above embodiments, it is preferred that the central support member is a hollow tubular structure.

[0017] In any of the above embodiments, it is preferred that the first drive shaft, the second drive shaft, the third drive shaft and the fourth drive shaft are respectively connected to the corresponding drive shaft driver. The drive shaft driver connected to the first drive shaft includes a slide rail and a driver fixing ring fixed on the outer wall of the central support member. The slide rail cooperates with the slider at the bottom of the slide block to slide. The driver fixing ring is fixed with the slide block and a reciprocating motion driver that drives the slider to move along the length direction of the slide rail. The slide block is connected to the first drive shaft.

[0018] Power is provided by the reciprocating motion driver, which drives the slide block and slider to reciprocate along the length of the slide rail, thereby enabling the transmission shaft to switch between forward and backward movement.

[0019] In any of the above embodiments, it is preferred that the reciprocating motion driver is a cylinder, the cylinder body of which is fixed on the driver fixing ring, and the telescopic end of which is fixed on the slide.

[0020] In any of the above embodiments, it is preferred that the reciprocating motion driver is a screw jack, the main body of which is fixed on the driver fixing ring, and the driving end is hinged to the slide.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0032] Example 1, such as Figures 1-2 As shown, the steel cage reinforcing ring tensioning device includes a central support member 5. Multiple sets of positioning support rods 1 with the same length direction are arranged on the outer side of the central support member 5. The multiple sets of positioning support rods 1 are arranged around the center line of the central support member 5 and the included angle between adjacent sets is the same. A spreading mechanism 2 is installed on the central support member 5 to drive the positioning support rods 1 to move closer to or away from the central support member 5. A transmission shaft driver 4 is installed at one end of the central support member 5. The transmission shaft driver 4 is connected to the spreading mechanism 2 through a transmission shaft 3.

[0033] When the drive shaft driver 4 is activated, the drive shaft 3 is pulled backward. The drive shaft 3 drives the positioning support rod 1 away from the central support member 5 through the spreading mechanism 2. Multiple sets of positioning support rods 1 are arranged around the center line of the central support member 5 until the positioning support rod 1 contacts the inner ring of the reinforcing ring 6, which provides temporary positioning and support for the reinforcing ring 6. With the help of the welding robot, multiple reinforcing rings can be welded sequentially along the axial direction of the steel cage, improving efficiency. When the reinforcing ring 6 is welded to the steel cage, the drive shaft driver 4 is activated again to push the drive shaft 3 forward. The drive shaft 3 drives the positioning support rod 1 closer to the central support member 5 through the spreading mechanism 2. The positioning support rod 1 disengages from the reinforcing ring 6 and returns to the initial state.

[0034] Example 2, as Figures 1-2 As shown, the steel cage reinforcing ring tensioning device includes a central support member 5. Multiple sets of positioning support rods 1 with the same length direction are arranged on the outer side of the central support member 5. The multiple sets of positioning support rods 1 are arranged around the center line of the central support member 5 and the included angle between adjacent sets is the same. A spreading mechanism 2 is installed on the central support member 5 to drive the positioning support rods 1 to move closer to or away from the central support member 5. A transmission shaft driver 4 is installed at one end of the central support member 5. The transmission shaft driver 4 is connected to the spreading mechanism 2 through a transmission shaft 3.

[0035] The positioning support rod 1 is provided in four sets, namely the first positioning support rod, the second positioning support rod, the third positioning support rod and the fourth positioning support rod. The first positioning support rod, the second positioning support rod, the third positioning support rod and the fourth positioning support rod are all arranged around the center line of the central support member 5 and the included angle between adjacent ones is the same. Corresponding to the four sets of positioning support rods, there are four sets of transmission shafts 3, namely the first transmission shaft, the second transmission shaft, the third transmission shaft and the fourth transmission shaft. The four sets of positioning support rods correspond one-to-one with the four sets of transmission shafts.

[0036] Each set of positioning support rods 1 uses an independent drive shaft 3 for transmission, ensuring transmission stability and extending its service life.

A driving connecting rod 2.5 is hinged to the connecting rod hinge seat 2.3, and the other end of the driving connecting rod 2.5 is hinged to the end of the main drive rod 2.4 near the first fixed seat 2.1.

[0038] When the drive shaft driver 4 is activated, the drive shaft 3 is pulled backward. The drive link 2.5, which is hinged to the connecting rod hinge seat 2.3, moves closer to the first fixed seat 2.1. The drive link 2.5 causes the included angle between the main drive rod 2.4 and the central support member 5 to increase. The end of the main drive rod 2.4 away from the central support member 5 moves away from the central support member 5, thereby driving the positioning support rod 1 away from the central support member 5. Multiple sets of positioning support rods 1 are arranged around the center line of the central support member 5 until the positioning support rod 1 contacts the inner ring of the reinforcing ring 6, which provides temporary positioning and support for the reinforcing ring 6.

[0039] When the drive shaft driver 4 is activated, the drive shaft 3 is pushed forward. The drive link 2.5, which is hinged to the connecting rod hinge seat 2.3, moves closer to the second fixed seat 2.2. The drive link 2.5 drives the angle between the main drive rod 2.4 and the central support member 5 to decrease, thus completing the closure of the opening mechanism 2.

[0040] Furthermore, a traveling roller 2.10, capable of moving linearly along the outer wall of the central support member 5, is rotatably mounted on the connecting rod hinge seat 2.3 to ensure the stability of the movement.

The drive shaft driver 4 connected to the first drive shaft includes a slide rail 4.1 fixed on the outer wall of the central support member 5 and a driver fixing ring 4.4. The slide rail 4.1 slides in cooperation with the slider 4.2 at the bottom of the slide block 4.3. The driver fixing ring 4.4 is fixed with the slide block 4.3 and a reciprocating motion driver 4.5 that drives the slider 4.2 to move along the length direction of the slide rail 4.1. The slide block 4.3 is connected to the first drive shaft.

[0045] The reciprocating motion driver 4.5 provides power to drive the slide block 4.3 and the slider 4.2 to reciprocate along the length of the slide rail 4.1, thereby enabling the transmission shaft 3 to switch between forward and backward movement.

[0046] Furthermore, the reciprocating motion driver 4.5 is an existing screw jack, the main body of which is fixed on the driver fixing ring 4.4, and its driving end is hinged to the slide 4.3.
