Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel cage insulation binding technology, and in particular to a quick steel cage insulation binding device. Background Technology
[0002] Reinforcing cages are a common structural component in bridge construction. On-site reinforcing cages are typically fabricated through rapid welding in a factory or manual binding. Due to limitations in civil engineering reinforcing cage binding techniques, intersecting reinforcing bars overlap to form a mesh, creating a closed loop. Furthermore, manual binding on-site is time-consuming and labor-intensive. If large electrical equipment is located near the structure, induced currents can easily form in the reinforcing cage during equipment operation. Prolonged exposure to this current can cause the reinforcing bars to remain in a heated state, affecting the fatigue durability of the reinforced concrete and posing safety hazards. Utility Model Content
[0003] The purpose of this utility model is to provide a quick and easy steel cage insulation binding device, which solves the technical problem that after long-term use, the upper and lower mold bases will be slightly misaligned, the positioning column cannot be accurately inserted into the positioning slot when the mold is closed, and the upper and lower mold bases cannot be closed, which cannot assist in positioning and hinders the mold closing, making the device unreliable.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A quick steel cage insulation binding device includes a connecting rod, with fixed arms fixedly connected to both ends of the connecting rod. One side of the fixed arm is rotatably connected to one side of the moving arm via a rotating shaft. The tail of the moving arm is provided with an automatic clamping rod and sleeved on the rotating shaft. The other side of the fixed arm is detachably connected to the other side of the moving arm. The moving arm and the fixed arm are connected to form a tubular structure.
[0006] In some embodiments, the outer edge of the fixed arm is provided with a boom lock and a boom lock core fixed together, and the boom is provided with a fixed arm lock control cavity that cooperates with the boom lock core.
[0007] In some embodiments, the boom lock cylinder has a barb at one end away from the boom lock, and the fixed boom lock control cavity has a backstop that cooperates with the boom lock cylinder. When the boom and the fixed boom are connected, the backstop hooks the barb on the boom lock cylinder.
[0008] In some embodiments, one end of the anti-reverse component is fixed inside the fixed arm lock control cavity, and a protrusion is provided on the end face facing the fixed arm lock control cavity. The protrusion is used to hook the barb on the boom lock cylinder.
[0009] In some embodiments, a torsion spring is provided at the connection between the automatic latching rod and the rotating shaft. The automatic latching rod is integrally formed with the boom and sleeved on the rotating shaft. The torsion spring has a certain elasticity, which allows the boom to remain in the open state for a long time before use.
[0010] In some embodiments, the boom, fixed boom, and connecting rod are all made of nylon material, which has good insulation properties.
[0011] In some embodiments, the opening of the tubular structure formed by the connection of the moving arm and the fixed arm at one end of the connecting rod forms a 90° angle with the opening of the tubular structure formed by the connection of the moving arm and the fixed arm at the other end.
[0012] In some embodiments, the connecting rod is cylindrical with an elliptical cross-section, allowing the robotic arm to precisely control the direction of the insulating fastener during quick binding.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention features an automatic locking lever on the boom, which, under the action of a torsion spring, keeps the boom in the open state. When inserting rebar, the boom and stationary boom self-lock. This invention not only achieves insulation of the rebar cage but also enables rapid binding of the cage, improving work efficiency even when used manually. Compared to existing rapid welding techniques, it provides superior insulation; compared to existing manual binding techniques, it reduces worker fatigue and increases binding efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5 A quick and efficient insulated rebar cage binding device includes a connecting rod 5, with fixed arms 3 fixedly connected to both ends of the connecting rod 5. The cross-section of the connecting rod 5 is elliptical. When binding rebar, the robotic arm can accurately and quickly control the position of the connecting rod 5.
[0024] The fixed arm 3 is semi-circular, with its arc-shaped bottom fixed to the connecting rod 5. One side is rotatably connected to the boom 1 via a rotating shaft 2. A through groove is provided on the fixed arm 3 near the rotating shaft 2. This through groove is used to engage with the automatic locking rod 13 on the boom 1. The automatic locking rod 13 can swing within the through groove, facilitating the engagement of the boom 1 and the fixed arm 3. Two fixed arm locking control chambers 31 are provided on the other side of the fixed arm 3. These chambers are used to lock the boom 1.
[0025] An automatic locking rod 13 is provided in the middle of the side of the boom 1 that is rotatably connected to the fixed arm 3. The automatic locking rod 13 is integrally formed with the boom 1. A torsion spring 4 that cooperates with the automatic locking rod 13 is provided on the rotating shaft 2, which can keep the boom 1 in the open state for a long time before use, thereby improving the efficiency of quick binding. During quick binding, the boom locking core 12 can automatically lock into the fixed arm locking control cavity 31 as the rebar is inserted. During manual binding, simply push it towards the rebar in the direction of the opening, and the boom 1 and the fixed arm 3 will connect into a tubular structure to complete the self-locking.
[0026] A boom lock 11 is fixed on the side of the boom 1 away from the pivot 2. A boom lock cylinder 12 is fixedly connected to the boom lock 11. A barb is provided at the end of the boom lock cylinder 12 away from the boom lock 11. A backstop 32 that cooperates with the boom lock cylinder 12 is provided in the fixed boom lock control cavity 31. When the boom 1 and the fixed boom 3 are connected, the backstop 32 hooks the barb on the boom lock cylinder 12.
[0027] One end of the anti-reverse component 32 is fixed inside the fixed arm locking cavity 31, and a protrusion 8 is provided on the end face facing the fixed arm locking cavity 31. The other end extends obliquely to the outlet of the fixed arm locking cavity 31. When it is necessary to release the fixed arm 3 and the movable arm 1, simply press the anti-reverse component 32 inward, and the protrusion 8 on the anti-reverse component 32 will release from the barb of the movable arm lock 11. Under the action of the torsion spring 4, the fixed arm 3 and the movable arm 1 are opened.
[0028] The boom 1, fixed boom 3, and connecting rod 5 are all made of nylon material, which has good insulation properties.
[0029] The opening of the tubular structure formed by the closing of the boom 1 and the fixed boom 3 is at a 90° angle to the opening of the tubular structure formed by connecting the boom 1 and the fixed boom 3 at the other end, which facilitates the binding of steel bars in different directions.
[0030] like Figure 6 As shown, when using this device, the movable arm 1 and fixed arm 3 at one end of the connecting rod 5 are fastened to the transverse reinforcement 6, and the movable arm 1 and fixed arm 3 at the other end are fastened to the longitudinal reinforcement 7, thus completing the binding of two steel bars in different directions.
