Description

Technical Field

[0001] This application relates to the field of construction equipment, and particularly to an intelligent tensioning device. Background Art

[0002] During the production of precast concrete column piles, it is necessary to stretch the steel strand cage used in the column piles to make the column piles have higher impact resistance. In the working process of the existing stretching device, when the vibration platform vibrates, the tensioning plate will generate a jumping gap, and the concrete slurry will flow out from the gap between the bottom of the tensioning plate and the mold bottom plate, affecting the quality of the column piles.

[0003] In the Chinese Patent Publication No. CN215618980U, a tensioning device is disclosed, which includes a plate body. The plate body is provided with tensioning screw holes and tensioning holes. One end of the plate body in contact with the mold bottom plate of the concrete pile mold is provided with a high-temperature resistant strong magnet. The tensioning plate can firmly adsorb on the mold bottom plate when the mold vibrates on the vibration platform, achieving the purpose of avoiding the generation of the problem that the tensioning plate jumps relative to the mold bottom plate and ensuring the quality of the concrete pile.

[0004] However, this method has great deficiencies. This device only designs the plate body. When manufacturing products of different models, different models of this device may be required for production, resulting in higher production costs. Summary of the Utility Model

[0005] In view of this, this application provides an intelligent tensioning device, which solves the problems of low adaptability and high production cost of the tensioning device in the prior art, improves the adaptability of the tensioning device, and reduces the cost at the same time.

[0006] An intelligent tensioning device provided by this application adopts the following technical solutions:

[0007] An intelligent tensioning device includes a tensioning component and a pre-embedded component. The pre-embedded component is used to limit the position after the steel strand is tensioned, and the tensioning component is used to tension the steel strand to a fixed position;

[0008] The pre-embedded component includes a pre-embedded disc and a limiting ring. The pre-embedded disc is circumferentially and uniformly provided with limiting holes. The limiting ring is arranged on one side of the limiting holes. The limiting ring includes a limiting plate and an arc-shaped square tube. One end of the arc-shaped square tube is provided with a fixing hole, and the other end is provided with an adjusting hole. Symmetrically arranged above and below the fixing hole are moving grooves. The arc-shaped square tube is fixedly connected with the pre-embedded disc. A connecting rod is arranged in the adjusting hole, and the connecting rod is rotatably connected with the arc-shaped square tube. A torsion spring is arranged on the connecting rod. A slider is arranged in the moving groove. One end of the limiting plate is fixedly connected through the connecting rod, and the other end is fixedly connected through the slider. The limiting plate is provided with a limiting groove, and the moving track of the limiting groove coincides with the fixing hole.

[0009] By adopting the above technical solution, first rotate the limit plate to the side away from the mounting hole, then pass the steel strand through the limit hole. At this time, under the action of the torsion spring, the limit plate will abut against the steel strand. Then use the tensioning assembly to pull the steel strand to a suitable position. At this time, the tensioning assembly passes the bolt through the limit groove, the fixing hole on the limit plate and the limit groove on another limit plate in sequence to fix the position of the limit plate. The steel strand will be fixed in the limit hole under the extrusion force of the limit plate and the embedded plate. This method can limit and fix various types of steel strands, improving the adaptability and compatibility of the tensioning device.

[0010] Optionally, the tensioning assembly includes an installation shell, a tensioning gripper, a tensioning pusher and a fixed limiter. The tensioning pusher includes two push cylinders, and the two push cylinders are respectively arranged at the top and bottom of the installation shell. The tensioning gripper is fixedly connected to the push end of the push cylinder. The fixed limiter is arranged in the installation shell and located between the two push cylinders.

[0011] By adopting the above technical solution, after the steel strand passes through the limit hole of the embedded plate, the end of the steel strand is gripped by the tensioning gripper, and the steel strand is pushed to a suitable position by the push of the push cylinder. The uniform force of the two push cylinders to pull the steel strand can ensure that the pulled steel strand moves smoothly and slowly, thus ensuring the safety of construction and the safety during future use.

[0012] Optionally, the fixed limiter includes a fixed disk, a fixed cylinder, a rotating motor, a limit disk, a screwdriver and a fixing bolt. The fixed disk and the limit disk are respectively arranged in the installation shell and located between the two push cylinders. The fixed disk is arranged on the side of the push cylinder close to the push end and is fixedly connected to the push cylinder. The limit disk is slidably connected to the two push cylinders and is located between the fixed disk and the embedded plate. Avoidance holes I are provided at the positions corresponding to the limit holes on the fixed disk and the embedded plate. The fixed cylinder is arranged on the fixed disk, and the push end of the fixed cylinder is fixedly connected to the limit disk. An installation hole is provided at the position corresponding to the fixing hole on the limit disk. The rotating motor is fixedly arranged on the fixed disk, and the driving end extends into the installation hole. The screwdriver is fixedly connected to the driving end of the rotating motor. The fixing bolt is arranged on the screwdriver.

[0013] By adopting the above technical solution, one end of the steel strand passing through the limit hole sequentially passes through the avoidance hole one at the corresponding position on the limit disc and the fixing disc, and then is clamped and fixed by the tensioning and clamping assembly. After pulling the steel strand to a proper position, through the simultaneous action of the fixing cylinder and the rotating motor, the fixing bolt is screwed into the fixing hole on the embedded disc to fix the position of the steel strand. The whole process is fully automated. Compared with the traditional wedge block, it avoids the wedge block being pulled out during the pulling process of the steel strand, which affects the construction progress and improves the work efficiency.

[0014] Optionally, the tensioning and clamping member includes a clamping disc, a clamping cylinder, a double rack, a gear and a gripper. The clamping disc is fixedly arranged at the pushing end of the pushing cylinder. Avoidance hole two is provided at the corresponding position on the clamping disc. The clamping cylinder is arranged at the edge of the clamping disc, and the pushing end of the clamping cylinder points to the avoidance hole two. The double rack is arranged at the pushing end of the clamping cylinder. The gears are symmetrically arranged on both sides of the double rack, and the gears are meshed with the double rack. A gripper is arranged at one end of the gear far away from the clamping cylinder. The gripper is used to grab the steel strand passing through the avoidance hole two.

[0015] By adopting the above technical solution, when the steel strand passes through the avoidance hole two on the clamping disc, at this time, control the clamping cylinder to push forward, the double rack moves forward, and the gears meshed with the double rack rotate simultaneously, driving the gripper to clamp and fix the steel strand. Fixing the steel strand in this way can adapt to various models of steel strands and improve the construction compatibility.

[0016] Optionally, the screwdriver is magnetic, and the fixing bolt and the screwdriver are magnetically adsorbed to each other.

[0017] By adopting the above technical solution, before fixing the embedded disc, it is necessary to place the fixing bolt in the installation hole, and the fixing bolt and the screwdriver need to be in contact. Under the adsorption effect of the magnetic force, it can ensure the tight connection between the screwdriver and the fixing bolt, avoiding the separation of the fixing bolt and the screwdriver during the pushing process of the fixing cylinder, and improving the construction completion and work efficiency.

[0018] Optionally, the limiting plate abuts against the embedded disc, and a threaded structure is provided in the fixing hole.

[0019] By adopting the above technical solution, the threaded structure in the fixing hole can ensure that the fixing bolt enters the fixing hole more smoothly, avoiding that multiple fixing bolts cannot enter the fixing hole at the same time, and at the same time avoiding the deviation of the position of the fixing bolt. The abutment of the limiting plate against the embedded disc can further increase the firmness of the fixing bolt after fixing.

[0020] Optionally, a rubber layer is provided at the position where the gripper grabs the steel strand.

[0021] By adopting the above technical solution, the rubber layer can further increase the friction between the gripper and the steel strand, and ensure that the contact between the gripper and the steel strand is a soft contact, which can not only prevent the gripper from slipping when pulling the steel strand, but also avoid the wear of the steel strand on the gripper, effectively extending the service life of the gripper.

[0022] In summary, the present application includes the following beneficial technical effects:

[0023] First, rotate the limit plate to the side away from the mounting hole, then pass the steel strand through the limit hole. At this time, under the action of the torsion spring, the limit plate will abut against the steel strand. Then use the tensioning assembly to pull the steel strand to a suitable position. At this time, the tensioning assembly passes the bolt through the limit groove, fixing hole on the limit plate and the limit groove on another limit plate in sequence to fix the position of the limit plate. The steel strand will be fixed in the limit hole under the extrusion force of the limit plate and the embedded plate. This method can limit and fix various types of steel strands, improving the adaptability and compatibility of the tensioning device.

[0024] One end of the steel strand passing through the limit hole passes through the avoidance holes one at corresponding positions on the limit plate and the fixed plate in sequence, and then is clamped and fixed by the tensioning and gripping assembly. After pulling the steel strand to a suitable position, through the simultaneous action of the fixed cylinder and the rotating motor, the fixing bolt is screwed into the fixing hole on the embedded plate to fix the position of the steel strand. The whole process is fully automated. Compared with the traditional wedge block, it avoids the wedge block being pulled out during the pulling process of the steel strand, which affects the construction progress, and improves the work efficiency.

[0025] When the steel strand passes through the avoidance hole two on the gripping plate, at this time, control the gripping cylinder to push forward, the double rack moves forward, and the gear meshing with the double rack rotates simultaneously, driving the gripper to grip and fix the steel strand. Fixing the steel strand in this way can adapt to various types of steel strands, improving the construction compatibility. BRIEF DESCRIPTION OF THE DRAWINGS
