Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical connection of steel bars in the construction industry, and in particular relates to a split extrusion device for modular steel bar extrusion sleeve connection joints. Background Art

[0002] The main mechanical connections of steel bars include sleeve extrusion connection, straight thread sleeve connection, and tapered thread sleeve connection. Among them, sleeve extrusion connection mainly uses an extruder to extrude and deform the steel sleeve so that the sleeve is tightly combined with the steel bar, thereby realizing the connection of the steel bar.

[0003] Among the mechanical connections of steel bars, sleeve extrusion connections are widely used in various construction projects due to their advantages such as high connection strength, fast construction speed, and strong adaptability. However, traditional sleeve extrusion equipment is usually large in size and complex in structure, which not only requires a large initial investment, but also often limits its flexibility and scope of application during on-site construction due to its operational complexity and high space requirements. In particular, in modular building construction, the connection of steel bars needs to be carried out between prefabricated modules, which places higher demands on the portability, modularity, and ease of operation of the connection equipment. Traditional extrusion equipment is difficult to meet these requirements, resulting in low construction efficiency and increased costs. In addition, during the extrusion process, existing sleeve extrusion equipment often has difficulty in accurately controlling the extrusion force and extrusion position, resulting in inconsistent bonding tightness between the sleeve and the steel bar, affecting the connection quality. At the same time, the maintenance and upkeep of the equipment are also relatively complex, increasing the difficulty and cost of construction. Summary of the Invention

[0004] The purpose of the utility model is to address the problems existing in the prior art and provide a split extrusion device for modular steel bar extrusion sleeve connection joints.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a split extrusion equipment for modular steel bar extrusion sleeve connection joints, comprising a pair of telescopic cylinders, each of which is provided with an auxiliary rod, each of which is provided with a pair of clamps for extruding the steel bars, an end seat being installed at one end of the auxiliary rod away from the telescopic cylinder, and a lifting ring being provided at one end of the end seat away from the auxiliary rod.

[0006] By adopting the above technical solution, the equipment can achieve efficient extrusion connection of the steel bar connecting sleeve through a pair of telescopic cylinders set on both sides of the steel bar. This dual-cylinder design ensures the stability and balance of the extrusion process, and improves the strength and reliability of the connection joint. The equipment adopts a modular design, including components such as telescopic cylinders, auxiliary rods, clamps, end seats and lifting rings. This design makes the equipment easy to assemble, disassemble and transport, and is also convenient for maintenance and upgrades.

[0007] Optionally, an oil inlet hole and an oil outlet hole are respectively provided on a pair of telescopic cylinders.

[0008] By adopting the above technical solution, the oil inlet hole is used to inject hydraulic oil into the telescopic cylinder to drive the extension and contraction of the cylinder; the oil discharge hole is used to discharge the hydraulic oil in the cylinder to achieve the resetting of the cylinder. By controlling the flow of hydraulic oil, precise control of the telescopic cylinder can be achieved to ensure the stability and accuracy of the extrusion process.

[0009] Optionally, the output shafts of the pair of telescopic cylinders are hollow, and the auxiliary rod is located inside the output shafts of the pair of telescopic cylinders.

[0011] Optionally, the clamp member includes a clamping plate, and a first opening and a second opening respectively opened at two ends of the clamping plate.

[0012] By adopting the above technical solution, the first opening and the second opening are used to accommodate the auxiliary rod, ensuring that the clamp can move stably on the auxiliary rod. Through reasonable opening design, a close fit between the clamp and the auxiliary rod can be ensured to prevent loosening or falling off during the extrusion process.

[0013] Optionally, the width of the first opening and the second opening are both smaller than the output shaft diameter of the telescopic cylinder.

[0014] By adopting the above technical solution, this design can ensure the stability of the clamp on the auxiliary rod, prevent the clamp from sliding or falling off due to excessive force during the extrusion process, and at the same time, help to improve the clamping force of the clamp on the steel bar connecting sleeve.

[0015] Optionally, the length of the second opening is twice the length of the first opening.

[0016] By adopting the above technical solution and increasing the length of the second opening, the stability of the clamp on the auxiliary rod can be further improved. At the same time, this design also facilitates the installation of the auxiliary rod and the steel bar.

[0017] Optionally, the fixture includes a mounting plate, and a pair of first pair of interfaces and a second pair of interfaces opened on the mounting plate, the pair of first pair of interfaces are symmetrically distributed on both sides of the second pair of interfaces, and the opening directions of the pair of first pair of interfaces and the second pair of interfaces are the same.

[0018] By adopting the above technical solution, the first pair of interfaces and the second pair of interfaces are used to connect other modules or components to achieve modularity and scalability of the equipment. Through the standardized interface design, other modules or components can be easily connected to meet different construction requirements.

[0019] Optionally, the end seat is cylindrical and has a threaded groove, and the lifting ring is connected to the end seat via a threaded column.

[0020] By adopting the above technical solution, the cylindrical end seat structure is simple, stable, and easy to process and install. The combination of the thread groove and the thread column can ensure the stability and firmness of the lifting ring, preventing it from falling off or being damaged during transportation and movement.

[0030] An auxiliary rod 2 is provided on each of the telescopic cylinders 1. The output shafts of the telescopic cylinders 1 are hollow. The auxiliary rod 2 is located on the inner side of the output shafts of the telescopic cylinders 1. The auxiliary rod 2 is connected to the output shafts of the telescopic cylinders 1 to support and transmit force. They also serve as the installation basis for the clamp 3 to ensure that the clamp 3 can stably clamp the steel bar connecting sleeve. Through the auxiliary rod 2, the force generated by the telescopic cylinder 1 can be evenly transmitted to the clamp 3, thereby achieving uniform extrusion of the steel bar connecting sleeve.

[0031] The auxiliary rod 2 is provided with a pair of clamps 3 for squeezing the steel bars. The clamp 301 is the main part of the clamp 3 and is used to directly clamp the steel bar connecting sleeve. The clamping effect of the clamp 301 can ensure that the steel bar connecting sleeve will not move or deflect during the extrusion process, thereby ensuring the accuracy and stability of the extrusion. The clamp 3 includes a clamp 301 and a first opening 302 and a second opening 303 respectively opened at both ends of the clamp 301. The clamp 301, the first opening 302 and the second opening 303 form an "H" shape.

[0038] Start the oil supply device and inject hydraulic oil into the telescopic cylinder 1 through the oil inlet 101. Adjust the pressure and flow of the oil supply device to ensure that the telescopic cylinder 1 can be extended and retracted at an appropriate speed and force.

[0039] The telescopic cylinder 1 is extended and drives the clamping plate 301 to squeeze the steel bar connecting sleeve. After squeezing, the connection quality of the steel bar and the sleeve is checked to ensure the close connection and stability between them.

[0040] After the extrusion operation is completed, disconnect the oil supply device from the telescopic cylinder 1, disassemble the clamp 3, and remove the equipment from both sides of the steel bar for easy transportation and movement to the next operation point.
