Description

Technical Field

[0001] The present application relates to the technical field of pile foundation construction, and in particular to a pile foundation reinforcement cage positioning device. Background Art

[0002] Steel cage refers to a cage-like structure made of steel bar material, which is mainly used to reinforce concrete structure. It is made of longitudinal steel bars and transverse steel bars interwoven to form a dense steel grid, which is then fixed inside the concrete structure with steel bars. It is a reinforcement material widely used in construction projects and earthwork projects, with the advantages of stable material, corrosion resistance, and convenient construction.

[0003] Patent application number CN202320891974.8 discloses a pile foundation steel cage positioning device, including a counterweight, a limit rod, an abutment block and a binding part. When in use, first measure the distance between the outside of the main reinforcement of the steel cage and the casing, adjust the position of the inner nut according to the distance, and then rotate the outer nut to clamp the two adjacent main reinforcements of the steel cage. This positioning device is set in four directions of the casing. When the concrete is poured, the steel cage will not be displaced due to the impact of the concrete, and the displacement error of the steel cage is effectively controlled. A steel wire rope or iron wire rope is tied to the abutment bolt, and a heavy object is tied to the other end and fixed outside the casing to prevent the device from falling into the hole, which is convenient for reuse and realizes green and material-saving construction.

[0004] However, in use, there are the following defects:

[0005] Although positioning devices are provided in four directions of the casing to position the steel cage, since stirrups are provided on the outer ring of the steel cage, the gap between the stirrups and the main reinforcement may cause the limit rod to be unable to extend into it, resulting in the inability to clamp, affecting the practicability of the device. Utility Model Content

[0006] The purpose of the present application is to provide a pile foundation steel cage positioning device, which solves the problem proposed in the background technology that although positioning devices are provided in four directions of the casing to position the steel cage, since the outer ring of the steel cage is provided with stirrups, the gap between the stirrups and the main reinforcement may cause the limit rod to be unable to extend into it, resulting in the inability to clamp, affecting the practicability of the device.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a pile foundation steel cage positioning device, comprising an outer frame, an adjusting rod, a support frame, a bidirectional screw and a battery, the top of the outer frame is slidably connected with a block, an adjusting rod is passed through the top of the side wall of the block, and the top of the block is threadedly connected with a limiting bolt, and the end of the adjusting rod facing the inner side of the outer frame is passed through a connecting rod, and the upper and lower ends of the connecting rod are respectively fixedly connected to the center of the side wall of the limiting rod, and support blocks are fixedly welded on both sides of the outer wall of the outer frame, and the top of the support block is respectively fixedly connected to the two ends of the bottom of the support frame, and a strip groove is opened below the top of the support frame, and a bidirectional screw is movably installed on the inner side of the strip groove, and threaded blocks are threadedly connected on both sides of the surface of the bidirectional screw.

[0008] In this technical solution, after the steel cage is lowered, an upper outer frame is placed on the outside of the foundation pit, and then the driving motor is powered on to start it, thereby driving the bidirectional screw rod to rotate. The steel cage can be vertically fixed through the electric push rod, hook and threaded block. During the rotation of the bidirectional screw rod, the threaded block moves in the strip groove, thereby driving the electric push rod and hook below to move. After the hook moves to the top of the steel cage, the electric push rod is started to drive the hook to descend, so that the hook can hook the top stirrup of the steel cage, and then the electric push rod is slightly contracted to tighten the hook, thereby completing the upper fixation of the steel cage. Since the hook can adjust its position freely, it can adapt to steel cages of different sizes, thereby improving the practicability of the device, and since the distance from the hook to both ends of the support frame is equal, when fixed During the adjustment process, the steel cage can be located in the center of the outer frame, and the scale can also read the distance between the steel cage and the outer frame. The steel cage can be laterally fixed through the clamping block, adjusting rod, connecting rod and limit rod. The clamping block can slide freely on the edge of the outer frame to select a position, and then slide the adjusting rod so that the end located on the inner side of the outer frame can extend from the gap of the steel cage, and then rotate the connecting rod to change the limit rod from being parallel to the adjusting rod to being vertical, and then tighten the fixing bolts to fix the connecting rod and the limit rod. At this time, the unfolded limit rod is located on the inner side of the steel cage, and the adjusting rod is pulled back so that the limit rod can be stuck in the gap of the steel cage. Limit rods are set simultaneously in multiple relative directions to pull the steel cage, thereby completing the fixation and improving the fixing effect and practicality of the device.

[0009] As an optional solution of the technical solution of the present application, the bottom of the threaded block is fixedly connected to an electric push rod, and the bottom of the electric push rod is fixedly connected to a hook.

[0010] As an optional solution of the technical solution of the present application, a fixing bolt is threadedly connected to the side wall of the adjusting rod outside the connecting rod.

[0011] As an optional solution of the technical solution of the present application, a driving motor is fixedly installed on the outer side wall of the support frame facing one end of the bidirectional screw rod, and the rear end of the transmission shaft of the driving motor is fixedly connected to the bidirectional screw rod.

[0012] As an optional solution of the technical solution of the present application, a battery is fixedly installed at the center of the top end of the support frame.

[0013] As an optional solution of the technical solution of the present application, a scale is fixedly installed on the top of the support frame on both sides of the battery.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can vertically fix the steel cage through the electric push rod, hook and threaded block. During the rotation of the bidirectional screw rod, the threaded block moves in the strip groove, thereby driving the electric push rod and hook below to move. After the hook moves to the top of the steel cage, the electric push rod is started to drive the hook to descend, so that the hook can hook the top stirrup of the steel cage, and then the electric push rod is slightly contracted to tighten the hook, thereby completing the upper fixation of the steel cage. Since the hook can freely adjust its position, it can adapt to steel cages of different sizes, thereby improving the practicality of the device.

[0016] 2. The present application can laterally fix the steel cage through the clamping block, adjusting rod, connecting rod and limiting rod. The clamping block can slide freely on the edge of the outer frame to select a position, and then slide the adjusting rod so that the end located on the inner side of the outer frame can extend from the gap of the steel cage. Then, the connecting rod is rotated to change the limiting rod from being parallel to the adjusting rod to being vertical. The connecting rod and the limiting rod are fixed by tightening the fixing bolts. At this time, the unfolded limiting rod is located on the inner side of the steel cage. The adjusting rod is pulled back so that the limiting rod can be stuck in the gap of the steel cage. The limiting rods are simultaneously set in multiple relative directions to pull the steel cage, thereby completing the fixation and improving the fixing effect and practicality of the device.
