Description
Technical Field
[0001] The utility model relates to the field of cast-in-place pile construction, in particular to a device for real-time measurement of the concrete liquid level height of bored cast-in-place piles. Background Art
[0002] At present, bored cast-in-place piles are widely used in the field of engineering construction to improve the bearing capacity of engineering structures such as bridges. For example, in the renovation project of the Canal Bridge on the East-West Avenue in Yuhang District, there are many bored cast-in-place pile constructions. When using the conduit method for concrete pouring, it is necessary to intermittently measure the height of the concrete liquid level to determine the conduit embedment depth and control the pile top elevation. The traditional method for measuring the height of the concrete liquid level of bored cast-in-place piles is generally for workers to use a steel wire rope and rely on touch and experience to measure the height of the concrete liquid level. This method is greatly affected by human factors, has large measurement errors, a slow measurement process, and cannot reflect the rising situation of the liquid level height in real time. When the liquid level is about to reach the empty pouring height, multiple measurements are required to ensure that the liquid level height can reach the top of the empty pile.
[0003] Therefore, at present, a technical solution is needed to solve the problems that the height of the concrete liquid level in the bored cast-in-place pile needs to be measured by workers inserting a steel wire rope, resulting in large errors and low measurement efficiency. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the problems that the height of the concrete liquid level in the bored cast-in-place pile needs to be measured by workers inserting a steel wire rope, resulting in large errors and low measurement efficiency, and to provide a device for real-time measurement of the concrete liquid level height of bored cast-in-place piles.
[0005] In a first aspect, the utility model provides a device for real-time measurement of the concrete liquid level height of bored cast-in-place piles, including a winch, a switch seat, and a lever.
[0006] Winch: A measuring rope is wound around the winch, and a touch ball is connected to the end of the measuring rope.
[0007] Switch seat: An installation seat and a support spring are arranged on the switch seat, and a microswitch is arranged between the installation seat and the support spring.
[0008] Lever: The lever is hinged to the installation seat, the lever can rotate around the installation seat, and abuts against the support spring. The measuring rope extends into the pile hole after bypassing the end of the lever.
[0009] The utility model relates to a device for real-time measurement of the height of the concrete liquid level in a bored cast-in-place pile. Before the concrete is poured, the touch ball is extended into the pile hole. The touch ball is in a suspended state, and its gravity acts on the measuring rope, so that the lever rotates downward to compress the support spring and continues to squeeze the micro switch located on the switch base downward, making the micro switch in a closed state and the winch not working. During the concrete pouring process, as the concrete liquid level in the pile hole rises, the concrete liquid level contacts the touch ball. The touch ball is subjected to the buoyancy of the concrete liquid level, and the measuring rope is not subjected to the gravity of the touch ball. On the switch base, the lever is subjected to the action of the support spring and rotates upward to disengage from the micro switch, so that the micro switch is turned on and the winch starts, driving the measuring rope to move upward, and then dragging the touch ball away from the concrete liquid level. After the touch ball leaves the concrete liquid level, the lever rotates downward again, pressing the micro switch, so that the winch stops working. That is, the length of the measuring rope collected by the winch each time is the height of the poured concrete this time. After this device is installed once, it can realize the real-time measurement of the height of the concrete liquid level during the whole pouring process, avoiding the empirical judgment of workers during the measurement process and improving the accuracy of the measurement result.
[0010] Preferably, a pulley is connected to the end of the lever, and the measuring rope bypasses the pulley.
[0011] Hanging the measuring rope on the lever through the pulley can reduce the friction force on the measuring rope and avoid the friction affecting the normal upward movement of the touch ball.
[0012] Preferably, a cross bar is provided at one end of the lever where the pulley is connected, and clamping plates are respectively provided at both ends of the cross bar. Both ends of the rotating shaft of the pulley are connected to the two clamping plates.
[0013] By providing a cross bar on the lever and respectively providing clamping plates at both ends of the cross bar, and installing the rotating shaft of the pulley between the two clamping plates, the installation of the pulley at the end of the lever is realized, so that when the pulley is subjected to the acting force of the measuring rope, it can rotate around the rotating shaft to reduce the friction force on the measuring rope.
[0014] Preferably, a roller counter is provided on the winch, and the roller counter is used to read the length of the measuring rope retracted and released.
[0015] The roller counter measures by converting the length into the number of turns of the roller. Specifically, when the roller rolls, the digital indicator on the roller records the number of turns, thereby measuring the length. Usually, the length range measured by this tool is within several meters. By measuring the length of the measuring rope collected by the winch in real time by the roller counter, the rising distance of the touch ball can be obtained.
[0016] Preferably, a cavity is provided inside the touch ball, a filling port communicating with the cavity is provided on the side wall of the touch ball, and a sealing plug is detachably provided on the filling port.
[0017] When measuring the height of the concrete liquid level, clean water or mud can be poured into the touch ball through the filling port so that its weight can meet the requirement of not sinking under the buoyancy in the concrete. When suspended, it can pull the lever rod and make the lever rod press the micro switch on the switch seat. After the measurement is completed, the mud or clean water is poured out through the filling port, which is convenient for the storage and transfer of the touch ball.
[0018] Preferably, the sealing plug is threadedly connected to the filling port.
[0019] It realizes the detachable connection between the sealing plug and the filling port, which is simple to install and disassemble, and has good sealing performance, and can prevent the clean water or mud added into the touch ball from leaking and affecting the normal measurement work.
[0020] Preferably, the touch ball is provided with a hanging ring, and the hanging ring is used to connect the measuring rope.
[0021] By setting a hanging ring on the touch ball, it is convenient to detachably connect the measuring rope to the touch ball. After use, the touch ball can also be removed from the measuring rope, which is convenient for the storage of the touch ball and the measuring rope.
[0022] Preferably, a limit clip is provided at the top of the support spring, the limit clip is provided with a card slot, and the lever rod is arranged in the card slot.
[0023] By setting a limit clip with a card slot at the top of the support spring, the lever rod is rotated and clamped into the card slot of the limit clip to ensure that the support spring can form a stable support for the lever rod and prevent the lever rod from falling off the support spring during the process of compressing the support spring.

[0041] Embodiment 1
[0042] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, a real-time measuring device for the height of the concrete liquid level of a bored cast-in-place pile includes a winch 1, a switch base 22, and a lever 3. A measuring rope 11 is wound around the winch 1. The end of the measuring rope 11 is connected with a touch ball 111. An installation base 22 and a support spring 21 are arranged on the switch base 22. A microswitch 23 is arranged between the installation base 22 and the support spring 21. The lever 3 is hinged to the installation base 22. The lever 3 can rotate around the installation base 22 and abuts against the support spring 21. The measuring rope 11 bypasses the end of the lever 3 and extends into the pile hole 4.
[0043] Before the concrete pouring, the touch ball 111 is inserted into the pile hole 4. The touch ball 111 is in a suspended state and is located at a position close to the inner wall of the pile hole 4 at a distance of 1 / 2 of the pile hole radius. Its gravity acts on the measuring rope 11, so that the lever 3 rotates downward to compress the support spring 21 and continues to squeeze the microswitch 23 located on the switch base 2 downward, making the microswitch 23 in a closed state and the winch 1 not working. During the concrete pouring process, as the concrete liquid level in the pile hole 4 rises, the concrete liquid level contacts the touch ball 111. The touch ball 111 is subjected to the buoyancy of the concrete liquid level. The measuring rope 11 is not affected by the gravity of the touch ball 111. On the switch base 2, the lever 3 is affected by the support spring 21 and rotates upward to disengage from the microswitch 23, so that the microswitch 23 is turned on and the winch 1 starts, driving the measuring rope 11 to move upward, and then dragging the touch ball 111 away from the concrete liquid level. After the touch ball 111 leaves the concrete liquid level, the lever 3 rotates downward again, pressing the microswitch 23, so that the winch 1 stops working. That is, the length of the measuring rope 11 collected by the winch 1 each time is the height of the concrete poured this time. After this device is installed once, the real-time measurement of the height of the concrete liquid level during the entire pouring process can be realized, avoiding the empirical judgment of workers during the measurement process and improving the accuracy of the measurement results.
[0044] Lever 3: A cross bar 32 is provided at the end of the lever 3. Clamping plates 321 are arranged at both ends of the cross bar 32. A pulley 31 is connected between the two clamping plates 321. The measuring rope 11 bypasses the pulley 31 and enters the pile hole 4, which can reduce the friction force received by the measuring rope 11 and avoid the influence of friction on the normal upward movement of the touch ball 111.
[0045] Winch 1: A roller counter 12 is arranged on the winch 1. The roller counter 12 is used to read the length of the measuring rope 11 retracted and released. The roller counter 12 measures by converting the length into the number of turns of the roller. Specifically, when the roller rotates, the digital indicator on the roller records the number of turns, so as to measure the length. Usually, the length measured by this tool is within several meters. By measuring the length of the measuring rope 11 collected by the winch 1 in real time through the roller counter 12, the rising distance of the touch ball 111 can be obtained.
[0046] Touch ball 111: There is a cavity 1111 inside the touch ball 111. A filling port 1112 communicating with the cavity 1111 is provided on the side wall of the touch ball 111. A sealing plug 1113 is detachably provided on the filling port 1112, preferably connected by threads, so that the sealing plug 1113 has good sealing performance for the cavity 1111 of the touch ball 111. When measuring the height of the concrete liquid level, clean water or mud can be poured into the touch ball 111 through the filling port 1112 to make its weight meet the requirement that it can be buoyed in the concrete without sinking. When suspended, it can pull the lever 3 and make the lever 3 press the micro switch 23 on the switch seat 2. After the measurement is completed, the mud or clean water is poured out through the filling port 1112, which is convenient for storing and transferring the touch ball 111. A hanging ring 1114 is provided at the top of the touch ball 111, which can facilitate the detachable connection between the measuring rope 11 and the touch ball 111. After use, the touch ball 111 can also be removed from the measuring rope, which is convenient for storing the touch ball 111 and the measuring rope 11.
[0047] Support spring 21: A limit clip 211 is provided at the top of the support spring 21. The limit clip 211 is provided with a card slot 2111. The lever 3 is arranged in the card slot 2111. The lever 3 is rotated around the mounting seat 22 and snapped into the card slot 2111 of the limit clip 211 to ensure that the support spring 21 can stably support the lever 3 and prevent the lever 3 from falling off the support spring 21 during the process of compressing the support spring 21.
[0048] The operation steps of this device include:
[0049] Step 1: Rotate the lever 3 on the mounting seat 22 so that the lever 3 abuts against the limit clip 211. When not affected by the gravity of the touch ball 111, the lever does not act on the micro switch 23. The wiring terminals of the micro switch 23 are the common terminal and the normally closed terminal. This wiring method can realize the closing of the trigger micro switch 6 circuit, and vice versa, the circuit is closed;
[0050] Step 2: Inject clean water or mud into the touch ball 111 so that its weight can ensure that the support spring 21 is compressed and the micro switch 23 is turned on under the buoyancy of the mud. Then, before pouring the concrete 5, lower the touch ball into the pile hole 4 until it is flush with the lower end of the conduit, and the horizontal position is at R / 2 from the hole wall;
[0051] Step 3: Reset and zero the roller counter 12;
[0052] Step 4: Turn on the main switch of the device. At this time, the pulley 31 is affected by the gravity of the touch ball 111, so that the micro switch 23 is in the triggered state, the circuit of the device is open, and the winch 1 is not started;
[0053] Step 5: After the concrete 5 is poured and the liquid level rises, when the contact ball 111 touches the concrete 5, the pulley 31 is not subjected to the gravity of the contact ball 111, the support spring 21 resets, the microswitch 6 resets, the device circuit closes, the winch 1 starts, winds up the measuring rope 11, and pulls the contact ball 111 up until the microswitch 23 triggers the circuit to break again. At this time, the height of the contact ball 11 rising shown by the roller counter 12. Adding this value to the distance from the lower end of the conduit to the bottom of the hole gives the height of the concrete liquid level. The programmable roller counter 12 can also be used to preset this content into the program.
[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
