Description

Technical Field

[0001] This utility model relates to a rebar cage bracket in the field of rebar cage processing and manufacturing technology. Background Technology

[0002] The main function of the reinforcing cage is similar to that of the longitudinal reinforcement in a column, primarily providing tensile strength. Since concrete has high compressive strength but low tensile strength, the reinforcing cage restrains the concrete, enabling it to withstand a certain axial tensile force. The reinforcing cage is cylindrical and is formed by rotation in the manufacturing process. Therefore, it is also rotating when it leaves the equipment after forming, requiring a support frame with rollers to hold it in place. The angle and position of the rollers on the support frame must match the outer circumference of the reinforcing cage. Currently, reinforcing cages come in various sizes, but the rollers and support frames are fixed, making adjustments impossible. The support frame must be custom-made according to the dimensions of the reinforcing cage being manufactured, increasing production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a rebar cage bracket that is applicable to rebar cages of various sizes, is easy and reliable to adjust, and effectively reduces production costs.

[0004] To achieve the above objectives, this utility model provides a rebar cage bracket, including a base, mounting seats are provided in the middle of both sides of the base, a pair of support frames are symmetrically arranged on the mounting seats, upper adjustable support mechanisms are provided on both sides of the upper part of the support frames, lower adjustable support mechanisms are provided on both sides of the middle part of the support frames, and the middle part of the support frames is connected to a tensioning adjustment mechanism, which is arranged on the base.

[0005] Compared with the prior art, the beneficial effect of this utility model is that by adjusting the opening and closing angle of a pair of support frames through the opening and closing adjustment mechanism, and cooperating with the adjustment of the angle of the adjustable support mechanism to support the steel cage of the corresponding size, it can be applied to a variety of steel cages of different sizes, and the adjustment is convenient and reliable, effectively reducing production costs.

[0006] As a further improvement of this utility model, the support frame includes a pair of main rods, the lower end of the main rods is hinged to the mounting base, the outer side of the middle part of the main rods is connected to the lower adjustable support mechanism, the upper part of the main rods is connected by an upper connecting rod, and the middle part of the main rods is provided with a pair of middle connecting rods.

[0007] This support frame, consisting of a pair of main rods, a pair of middle connecting rods, and an upper connecting rod, forms a frame structure that ensures overall structural strength while also saving materials.

[0008] As a further improvement of this utility model, the upper adjustable support mechanism includes a short inclined rod set at the top of the main rod. The outer side of the short inclined rod is bolted to the tip of the upper fan-shaped plate. An upper arc-shaped groove is opened on the wide part of the upper fan-shaped plate. The upper arc-shaped groove is bolted to the short inclined rod. An extended upper rod is processed on one side of the outer edge of the upper fan-shaped plate. An upper support roller is provided at the end of the extended upper rod.

[0009] In this way, there is a certain angle between the short diagonal bar and the main bar. The upper fan-shaped plate rotates around its tip to determine the angle. After the angle is determined, bolts are inserted into the lower arc groove to fix the upper fan-shaped plate and the short diagonal bar. In this way, the angle of the upper roller relative to the short diagonal bar is adjusted.

[0010] As a further improvement of this utility model, the lower adjustable support mechanism includes a lower sector plate, the tip of which is bolted to the main rod, a lower arc groove is provided on the wide part of the lower sector plate, the lower arc groove is bolted to the main rod, and an extended lower rod is processed on one side of the outer edge of the lower sector plate, with a lower support roller provided at the end of the extended lower rod.

[0011] The lower sector plate is rotated around its tip to determine the angle. Once the angle is set, bolts are inserted into the lower arc groove to fix the lower sector plate to the main rod. In this way, the angle of the lower roller relative to the main rod is adjusted.

[0012] As a further improvement of this utility model, the tensioning mechanism adjustment mechanism includes a bidirectional lead screw. The two ends of the bidirectional lead screw are connected to fixed bearings respectively set at both ends of the base. One end of the bidirectional lead screw passes through the fixed bearing and is connected to the geared motor. The middle part of the bidirectional lead screw is sleeved on the support bearing, which is set in the middle of the base. A movable nut is sleeved on both the forward and reverse parts of the bidirectional lead screw. A movable seat is fixed on the movable nut. The movable seat is hinged to one end of the tensioning rod, and the other end of the tensioning rod is hinged to the fixed seat. The fixed seat is fixedly connected to a pair of connecting rods.

[0013] When the geared motor rotates forward, it drives the bidirectional lead screw to rotate, and the two moving nuts move towards each other simultaneously. This causes the support frame to close together via the tensioning rod, thus increasing the distance between the pair of upper and lower rollers to support the small-sized steel cage. Conversely, when the geared motor rotates in reverse, the two moving nuts move away from each other simultaneously, thus opening the support frame and increasing the distance between the pair of upper and lower rollers to support the large-sized steel cage.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1-2 The steel cage bracket shown includes a base 12, with mounting seats 13 arranged in the middle of both sides of the base 12. A pair of support frames are symmetrically arranged on the mounting seats 13. The upper two sides of the support frames are provided with upper adjustable support mechanisms, and the middle two sides of the support frames are provided with lower adjustable support mechanisms. The middle of the support frames is connected to a tensioning adjustment mechanism, which is arranged on the base 12.

[0019] The support frame includes a pair of main rods 18. The lower end of the main rods 18 is hinged to the mounting base 13. The outer side of the middle part of the main rods 18 is connected to the lower adjustable support mechanism. An upper connecting rod 19 is connected between the upper parts of the main rods 18. A pair of middle connecting rods 20 are provided between the middle parts of the main rods 18.

[0020] The upper adjustable support mechanism includes a short diagonal bar 6 located at the top of the main rod 18. The outer side of the short diagonal bar 6 is bolted to the tip of the upper fan-shaped plate 5. An upper arc-shaped groove 4 is formed on the wide side of the upper fan-shaped plate 5, and the upper arc-shaped groove 4 is bolted to the short diagonal bar 6. An extended upper rod 3 is machined on one side of the outer edge of the upper fan-shaped plate 5, and an upper support roller 2 is provided at the end of the extended upper rod 3. The lower adjustable support mechanism includes a lower fan-shaped plate 17. The tip of the lower fan-shaped plate 17 is bolted to the main rod 18. A lower arc-shaped groove 16 is formed on the wide side of the lower fan-shaped plate 17, and the lower arc-shaped groove 16 is bolted to the main rod 18. An extended lower rod is machined on one side of the outer edge of the lower fan-shaped plate 17, and a lower support roller 15 is provided at the end of the extended lower rod.

[0021] The tensioning mechanism adjustment mechanism includes a bidirectional lead screw 9. Both ends of the bidirectional lead screw 9 are connected to fixed bearings 10 respectively located at both ends of the base 12. One end of the bidirectional lead screw 9 passes through the fixed bearing 10 and is connected to the reduction motor 14. The middle part of the bidirectional lead screw 9 is sleeved on the support bearing, which is located in the middle of the base 12. A movable nut 11 is sleeved on both the forward and reverse parts of the bidirectional lead screw 9. A movable seat 8 is fixed on the movable nut 11. The movable seat 8 is hinged to one end of the tensioning rod 7, and the other end of the tensioning rod 7 is hinged to the fixed seat 21. The fixed seat 21 is fixedly connected to a pair of connecting rods 20.

[0022] In this invention, the support frame consists of a pair of main rods 18, a pair of intermediate connecting rods 20, and an upper connecting rod 19, forming a frame structure that ensures overall structural strength while saving materials. A fixed seat 21 is fixedly connected between the middle sections of the intermediate connecting rods 20 for hinged connection with the tensioning rod 7.

[0023] In use, if the steel cage 1 is small, the reduction motor 14 rotates forward, driving the bidirectional lead screw 9 to rotate. The two moving nuts 11 move towards each other simultaneously, thereby closing the support frame towards each other through the tensioning rod 7. This allows the gap between the pair of upper rollers 2 and the pair of lower rollers 15 to support the small steel cage 1. If the steel cage 1 is large, the reduction motor 14 rotates in reverse, and the two moving nuts 11 move away from each other simultaneously, thereby opening the support frame and increasing the gap between the pair of upper rollers 2 and the pair of lower rollers 15 to support the large steel cage 1.

[0024] After initially adjusting the opening and closing angle of the support frame according to the diameter of the steel cage 1, further fine adjustments to the angles of the upper support roller 2 and the lower support roller 15 are needed based on the dimensions of the steel cage 1. The short inclined rod 6 and the main rod 18 have a certain angle of inclination. The upper sector plate 5 is rotated around its tip to determine the angle. Then, bolts are inserted into the lower arc groove 16 to fix the upper sector plate 5 to the short inclined rod 6, thus adjusting the angle of the upper support roller 2 relative to the short inclined rod 6. Similarly, the lower sector plate 17 is rotated around its tip to determine the angle. Then, bolts are inserted into the lower arc groove 16 to fix the lower sector plate 17 to the main rod 18, thus adjusting the angle of the lower support roller 15 relative to the main rod 18.

[0025] By adjusting the opening and closing angle of the support frame and the angle of the upper roller 2 and the lower roller 15, the entire bracket can support the steel cage 1 of the corresponding size. After the steel cage 1 is sent out of the production equipment, it can be supported by the upper roller 2 and the lower roller 15. The steel cage 1 is still rotating when it is discharged, and the upper roller 2 and the lower roller 15 rotate with the steel cage 1 until the steel cage 1 is completely manufactured and the manufacturing equipment stops rotating. Then the steel cage 1 can be lifted from the rollers by the overhead crane.

[0026] This utility model can be adapted to various sizes of steel cages 1 by adjusting the opening and closing angle of the support frame and the angle of the upper roller 2 and the lower roller 15. It is convenient to use, simple to operate, and the overall structure is not complicated, effectively reducing production costs.
