[0023] Example 1
[0024] See Figures 1 to 3 This utility model provides a concrete pile monitoring device, including a detachable main frame 2 fixed in a steel cage 1. The main frame 2 is frame-shaped, and a monitoring unit 3 is fixedly installed in the middle of the upper end of the main frame 2. The monitoring unit 3 includes a light emitter, a voice broadcaster and a distance detector.
[0025] Several sliding cylinders 4 are provided on the side wall of the main frame 2. A sliding rod 5 is slidably installed in each sliding cylinder 4. A connecting unit 6 is fixedly installed at one end of the sliding rod 5. Each connecting unit 6 is detachably connected to one of the main bars of the steel cage 1.
[0026] A traction rope 7 is fixedly installed at the upper end of the main frame 2.
[0027] After construction is completed, the traction rope 7 facilitates the disassembly and recycling of the main frame 2 from the steel cage 1. The main frame 2 can be slowly pulled out of the pile hole by the traction rope 7, which facilitates the cleaning, maintenance and reuse of the device, improves the turnover efficiency of the device and reduces construction costs.
[0028] The light emitter is fixedly installed in the middle of the upper surface of the main frame 2, the voice broadcaster is located below the light emitter, and the distance detector is located below the voice broadcaster. The distance detector, the light emitter, and the voice broadcaster form an electrical control circuit.
[0029] Furthermore, the distance detector is an infrared distance detector. During the concrete pouring process of the pile foundation, this device emits infrared rays downwards to the concrete pouring surface, which can monitor the distance from the lower concrete pouring surface to the device in real time.
[0030] The distance voice broadcaster can broadcast the distance status during the process of the infrared distance detector monitoring the distance from the lower concrete pouring surface to the design height, so as to remind the concrete operators to pay attention to the pouring situation at all times;
[0031] The emitter is an infrared emitter that emits multiple beams of red light upwards. When the concrete pouring surface reaches the design height, it will cover the infrared emitter. At this time, the red or green light will suddenly disappear, and the concrete surface will be judged to have reached the design height.
[0032] The connecting unit 6 includes a mounting base 8 fixedly mounted on the sliding rod 5. The mounting base 8 is U-shaped, and the closed end of the mounting base 8 is fixedly connected to the sliding rod 5.
[0033] A limiting rod 9 is rotatably installed at each end of the opening of the mounting base 8, with one end of the limiting rod 9 extending into the opening of the mounting base 8.
[0034] A torsion spring is installed between the limit rod 9 and the mounting base 8.
[0035] A pull rope is provided on one side of the traction rope 7. One end of the pull rope is fixedly connected to the limiting rod 9 of multiple connecting units 6. The pull rope is fixedly installed at one end of the limiting rod 9 near the sliding rod 5.
[0036] A tension spring 10 is installed between the sliding rod 5 and the main frame 2.
[0037] After the concrete is poured, before lowering the steel cage 1, the main frame 2 is connected to the steel cage 1 through the connecting unit 6. First, according to the position of the main reinforcement of the steel cage 1, the sliding rod 5 is slid in the sliding cylinder 4 so that the mounting seat 8 is aligned with the main reinforcement.
[0038] Because a torsion spring is installed between the limiting rod 9 and the mounting base 8, in its natural state, the limiting rod 9 rotates into the opening of the mounting base 8 under the action of the torsion spring, maintaining a closed tendency. When the mounting base 8 is aligned with the main reinforcement, the main reinforcement is placed into the opening of the mounting base 8, and the limiting rod 9 is pried open so that it passes over the main reinforcement. Under the elastic force of the torsion spring, the limiting rod 9 automatically rotates back to its original position and locks the main reinforcement. At this time, the mounting base 8 is located between the stirrups of the steel cage 1. Under the action of the stirrups of the steel cage 1, the fixed connection between the main frame 2 and the steel cage 1 is achieved.
[0039] The fixed steel cage 1 is lowered into the pile hole by the traction rope 7. During the lowering process, the monitoring unit 3 works in real time. When it is necessary to disassemble the main frame 2, the pull rope is pulled. The pull rope is connected to the end of each limit rod 9 near the sliding rod 5. Pulling the pull rope will drive the limit rod 9 to rotate around the rotation point between it and the mounting base 8, overcoming the elastic force of the torsion spring, so that the limit rod 9 is disengaged from the position that is stuck to the main reinforcement. Under the action of the tension spring 10, the connecting unit 6 is separated from the main reinforcement of the steel cage 1. At this time, the main frame 2 can be separated from the steel cage 1.
[0040] When using this utility model, before lowering the reinforcing cage 1 of the cast-in-place pile, the main frame 2 is installed inside the reinforcing cage 1 according to the design elevation position, and the traction rope 7 is thrown out to the upper operating surface. Then the reinforcing cage 1 is lowered. During the concrete pouring process, the distance between the concrete pouring surface and the design height can be monitored in real time by the instrument device and a voice broadcast will be given as a reminder. When the concrete surface reaches the design height, the voice broadcast will emit a warning sound, and at the same time the red light emitted by the infrared emitter will be covered by the concrete and the light will disappear. Therefore, the condition of the concrete pouring surface can be monitored by both the voice warning and the disappearance of the light. After the pouring is completed, the device can be lifted out by the traction rope 7, cleaned and reused.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
