Description

Technical Field

[0001] The utility model relates to the technical field of steel bar positioning devices, in particular to a positioning device for the steel bar protection layer imitating a wooden pile. Background Technique

[0002] Quality problems are inevitable in the construction of pile foundation projects, especially the deviation of the steel cage hoisting. If the steel cage is displaced, it will lead to insufficient thickness of the steel cage protection layer at least, and the phenomenon of steel bar leakage at worst, seriously affecting the internal quality of the pile foundation. Therefore, during the process of hoisting the steel cage, it is necessary to strictly control the position of the steel cage during installation to ensure its accuracy requirements. At this time, a positioning device for the steel bar protection layer imitating a wooden pile is needed.

[0003] According to the Chinese patent with the application number 202221948651.X, a positioning device for improving the positioning accuracy of the pile foundation steel cage is proposed. Using the principle that three points determine a circle, the operator can adjust the position of the positioning components to push the steel cage to adjust its position. The positioning components jointly push the steel cage until the steel cage reaches the central position of the pile hole. During this process, the lifting tool on the crane moves continuously with the change of the position of the steel cage, so that the steel cage always maintains a vertical state. Then, the steel cage is slowly lowered until it is placed at the center of the pile hole. The steel cage completed by using this method for the hoisting process is not likely to have deviation in the placement position, effectively improving the pile forming quality.

[0004] However, when the equipment in the above patent positions the steel cage, the staff needs to rotate each threaded rod in turn to make the positioning plate at its other end position the steel cage, and manual operation may lead to inaccurate position or uneven force of the positioning plate during the fixing process. Content of the Utility Model

[0005] Aiming at the above-mentioned shortcomings of the prior art, the utility model provides a positioning device for the steel bar protection layer imitating a wooden pile, which can effectively solve the problem that the position of the positioning plate may be inaccurate or the force is uneven during the fixing process in the prior art.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions:

[0007] The utility model provides a positioning device for the steel bar protection layer imitating a wooden pile, including a casing vertically arranged underground and a steel cage inside the casing. A base is arranged at the top of the casing, and a rotating seat is rotatably connected to the top of the base through a driving component. A plurality of positioning components are circularly and arrayedly distributed inside the rotating seat;

[0008] The positioning component includes a through groove opened inside the rotating seat. A sliding sleeve is rotatably connected inside the through groove. A sliding rod is slidably connected to the inner wall of the sliding sleeve.

The bottom of the other end of the sliding rod is rotatably connected to a connecting rod, and the bottom end of the connecting rod is rotatably connected to a positioning plate. The inner wall of the positioning plate contacts the outer side of the steel cage.

[0009] According to the above-mentioned positioning device for the steel bar protection layer of the imitation wooden pile, the driving component includes two bearing plates symmetrically and fixedly installed on the top of the base. A threaded rod is rotatably connected between the two bearing plates. A toothed plate is sleeved on the outer side of the threaded rod. The bottom of the toothed plate contacts the top of the casing. An external toothed ring is fixedly installed on the outer wall of the rotating seat. The toothed plate meshes with the external toothed ring. A motor for driving the threaded rod to rotate is fixedly installed on the outer side of one of the bearing plates.

[0010] According to the above-mentioned positioning device for the steel bar protection layer of the imitation wooden pile, limiting rods are fixedly installed on the outer walls of multiple positioning plates. Limiting grooves for slidably connecting with them are opened at corresponding positions on the inner wall of the casing for each limiting rod.

[0011] According to the above-mentioned positioning device for the steel bar protection layer of the imitation wooden pile, an annular groove is opened on the top of the base. An annular plate is slidably connected in a limited manner inside the annular groove, and the top of the annular plate is fixedly connected to the bottom of the rotating seat.

[0012] According to the above-mentioned positioning device for the steel bar protection layer of the imitation wooden pile, there are three positioning components and they are distributed in an equilateral triangle. The axes of the casing, the steel cage, the base, and the rotating seat coincide.

Positioning bolts are threadedly connected inside the plurality of threaded holes, and the bottom ends of the positioning bolts extend into the ground.

[0014] The technical solution provided by the present utility model, compared with the known prior art, has the following beneficial effects:

[0015] Through the mutual cooperation of the driving component and the positioning component of the present utility model, when the rotating seat rotates, by using the mutual cooperation of the sliding sleeve and the sliding rod, the sliding rod rotates around the center of the rotating shaft, and the connecting rod at the other end drives the positioning plate to move towards the steel cage. Using the principle that three points determine a circle, the position of the steel cage is centered and positioned, which is an important step to ensure that the steel bars in the concrete structure can be evenly distributed and play the strengthening and supporting roles required by the design, and prevent the position of the positioning plate from being inaccurate or the force being uneven during the fixing process due to manual operation, improving the use effect of the device.
