[0032] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0033] In order to solve various construction quality problems such as difficulty in supervision and random inspection when hollow anchor rods are not driven, driven too little, or missed, the embodiments of the present utility model provide an anchor rod detection device and an anchor rod detection system, which can realize all-round supervision and rapid and accurate detection of the length and quantity of anchor rods, and can realize post-event supervision without on-site inventory, thereby greatly improving the efficiency and quality of supervision.

[0034] Figure 1 This is a schematic diagram of the structure of an anchor rod detection device in one embodiment of the present utility model. Figure 1 As shown, the anchor bolt detection device includes: an electronic storage identifier 200 and a detection assembly 300 for installation in an anchor bolt 400. The detection assembly 300 includes a detection line 301 and a voltage detection element 302. The electronic storage identifier 200 is connected to the detection line 301, and the voltage detection element 302 is arranged on the detection line 301. The electronic storage identifier 200, the detection line 301, and the voltage detection element 302 are connected in series to form a closed circuit for detecting the detection voltage value.

[0035] In this embodiment, the electronic storage identifier is actually an electronic tag, also known as a radio frequency tag, which can communicate with a reader / writer via radio waves, transferring information between them. The tag is used to transmit stored data or information to the reader / writer via an antenna. Communication between the reader / writer and the electronic tag is achieved via radio frequency (RFID) signals, enabling simultaneous identification of multiple electronic tags and high-speed, large-scale reading. The electronic tag has a large storage capacity, a long storage time, and data can be updated at any time, providing read / write functionality. Specifically, the electronic storage identifier includes an antenna and an electronic chip. Exemplarily, the electronic chip is a KX2005X-BT chip. The electronic chip communicates with the data reader / writer via the antenna. The antenna is used to receive detection commands from the data reader / writer and simultaneously provides power for the closed circuit (which can also be powered by an external power source). The closed circuit generates and stores detection voltage values ​​in the electronic chip. The chip can also be used to return data stored in the electronic chip, such as the detection voltage value, to the data reader / writer. The electronic storage identifier can be mounted on the anchor bolt's baffle 401 (located at one end of the bolt) by spot welding, or mounted on one end of the bolt body. Alternatively, the electronic storage identifier can be mounted on neither the bolt 400 nor the anchor bolt baffle 401 (not mounted), in which case the electronic storage identifier is also located at one end of the bolt. This device is applicable to bolts with hollow sections. When inspecting the bolts, the above-mentioned bolt inspection device is mounted on each bolt, and the detection component is mounted within the hollow section of the bolt.

[0036] The anchor rod detection device further determines whether the actual installation length of the corresponding anchor rod is the same or consistent with the preset installation length (i.e., the factory length of the anchor rod) by detecting the detection voltage value of the above-mentioned circuit loop. This can detect whether the anchor rod has been artificially damaged during the construction and installation process, causing its length to change, thereby causing a construction quality risk of using a shorter length. This anchor rod detection method can quickly, effectively, simply, conveniently, and accurately detect whether there is a construction quality problem of using a shorter length to fill the anchor rod installation. It can also avoid the construction supervisor being on site at any time during the entire construction process, thereby affecting work efficiency, or pulling out all the installed anchor rods for inventory. The full inspection is less difficult, thereby achieving effective supervision of the anchor rod construction quality.

[0037] In some embodiments, the voltage detection element is an impedance element. Specifically, the impedance element is a resistor element. The number of the resistor element can be set to one, and the resistor element is set at one end of the anchor rod away from the electronic storage identifier, such as Figure 2The number of resistance elements can also be set to multiple, which are arranged at different positions of the detection line, and at least one of which is arranged at the end of the anchor rod away from the electronic storage identifier. In this case, the resistance values of the multiple resistance elements can be the same or different, which are not specifically limited here. In these embodiments, the detection line, resistance elements and electronic storage identifier form a circuit closed loop in series.

[0038] Specifically, after the anchor rod detection device is installed on the anchor rod and installed on the anchor rod, at least one resistance element is fixedly installed at the bottom end of the anchor rod. By arranging the impedance element on the detection line, the voltage detection accuracy can be improved. The resistance values of the resistance elements installed in anchor rods of different lengths can be the same or different, which are not specifically limited here.

[0039] In other embodiments, the voltage detection element is an electronic tag. As shown in Figure 3 In the anchor rod detection device shown, the electronic tag is arranged at the end of the anchor rod away from the electronic storage identifier, i.e. the electronic chip is fixedly installed at the bottom of the anchor rod. In some embodiments, as shown in Figure 3 The electronic tag includes an electronic chip and an antenna 3021. In other embodiments, the electronic tag can also only include an electronic chip.

[0040] In some embodiments, the detection line is a double parallel line, one end of which is connected to the electronic storage identifier, and the other end is arranged at the end of the anchor rod away from the electronic storage identifier. That is, after the double parallel line is installed in the anchor rod, the other end of the double parallel line is provided with or connected to a resistance element, and is fixedly arranged at the bottom of the anchor rod.

[0041] In other embodiments, the detection line can also be formed by folding a wire, one end of which is connected to the electronic storage identifier, and the other end is arranged at the end of the anchor rod away from the electronic storage identifier, i.e. the other end is provided with or connected to a resistance element and is fixedly installed at the bottom of the anchor rod.

[0042] In some embodiments, the length of the detection line is the same as the preset installation length of the corresponding anchor rod, or the length of the detection line is slightly greater than the preset installation length of the corresponding anchor rod. Specifically, during construction, in the absence of human damage to the anchor rod, when the electronic storage identifier is installed at the top end of the corresponding anchor rod and connected to one end of the detection line, and the other end of the detection line is installed at the bottom end of the hollow part of the anchor rod, the length of the detection line is the same as the preset installation length of the corresponding anchor rod, as shown in Figure 3For example, a 3m detection line is installed inside a 3m anchor rod, a 4m detection line is installed inside a 4m anchor rod, etc. When the electronic storage identifier is spot welded to the edge of the anchor rod baffle or other parts of the anchor rod body except the top, the length of the detection line is slightly longer than the preset installation length of the corresponding anchor rod, such as Figure 2 As shown. For example, the preset installation length of the anchor rod is 3m, and the length of the detection line is 3.2-3.3m; the preset installation length of the anchor rod is 4m, and the length of the detection line is 4.2-4.3m, etc., that is, the length of the detection line exceeds the preset installation length of the corresponding anchor rod by 20-30cm. The length of the detection line mentioned here is the length of the double parallel line or the length of the part formed by folding a wire in half. In each embodiment, as Figure 2 and Figure 3 The thickness of the voltage detection element shown in FIG is negligible.

[0043] In some embodiments, a connector is provided at the connection between the detection line and the electronic storage identifier, that is, a connector is provided at the end of the detection line that is connected to the electronic storage identifier. The connectors provided on detection lines of different lengths have interfaces of different physical forms. Connecting detection lines of different lengths to corresponding electronic storage identifiers via connectors of different physical forms provides anti-destruction protection and prevents cross-use.

[0044] Exemplarily, a detection line of 3m or slightly longer than 3m is connected to the electronic storage identifier installed on the 3m anchor rod through the connector with a circular interface thereon, and a detection line of 4m or slightly longer than 4m is connected to the electronic storage identifier installed on the 4m anchor rod through the connector with a square interface thereon, and so on. In this way, the detection lines and anchor rods of corresponding lengths are locked one-to-one through the connectors with interfaces of different physical forms on the detection lines of different lengths, so that the detection lines of corresponding lengths cannot be used in series between anchor rods of different lengths, thereby preventing the mixing of detection lines of different lengths. For example, the 3m detection line can be connected to the electronic storage identifier on the 3m anchor rod and to the electronic storage identifier on the 4m anchor rod, effectively avoiding the occurrence of inaccurate anchor rod length detection due to the mixing of detection lines of incompatible lengths.

[0045] In some embodiments, the anchor detection device further comprises a double-layer shell, the electronic storage identifier comprises an antenna and an electronic chip, and the electronic chip is disposed in the bottom layer of the double-layer shell.

[0046] Specifically, the electronic chip in the electronic storage identifier is wrapped by a double-layer shell and arranged in the inner layer of the double-layer shell. The double-layer shell is made of nylon and glass fiber mixed material, and the buffer rubber is filled between the double-layer materials to double protect the electronic chip. The double-layer shell has good performance of moisture-proof, dust-proof, explosion-proof, waterproof, impact-proof, etc., which can effectively protect the electronic chip to be still used normally in various complex and harsh environments. The double-layer shell structure can reduce the influence of cement on the electronic chip during installation and grouting of the anchor rod detection device, and can withstand a certain thickness of cement, thereby effectively protecting the electronic chip so that it can still work normally and maintain good performance. Since the concrete greatly attenuates the radio frequency signal, in order to ensure that the electronic chip can still be normally identified after being deeply buried in the concrete, the double-shell structure is used to protect the electronic chip, which can greatly reduce the influence of the concrete on the performance of the chip.

[0047] Figure 2 and Figure 3 are structural schematic diagrams of anchor rod detection systems in an embodiment and another embodiment of the utility model respectively. As shown in Figure 2 or 3, the utility model embodiment further provides a kind of anchor rod detection system, and the system includes the anchor rod detection device in any one embodiment described above and data read-write equipment 100, and the data read-write equipment 100 is communicated with the electronic storage identifier 200 in the anchor rod detection device.

[0048] Specifically, the data read-write equipment is used to write the anchor rod construction parameter corresponding to the anchor rod in the electronic storage identifier, or, read the detection voltage value and anchor rod construction parameter stored in the electronic storage identifier.

[0049] Specifically, data read-write equipment can be mobile (handheld) radio frequency identification (RFID) read-write equipment or fixed RFID read-write equipment set in construction site, including acquisition module, mainboard, touch screen and battery etc., wherein acquisition module is used to send detection instruction or reading instruction to the antenna in electronic storage identifier to make the antenna return the detection voltage value or anchor rod construction parameter stored in the electronic chip in electronic storage identifier to acquisition module, so as to read the detection voltage value and anchor rod construction parameter. One RFID read-write equipment can remotely, non-contact batch read the data, information stored in multiple electronic storage identifiers, and also can batch write the anchor rod construction parameter corresponding to the anchor rod to multiple electronic storage identifiers. Data reading, writing etc. between data read-write equipment and electronic storage identifier are realized by GS1 standard protocol to realize communication, which can realize large batch remote, non-contact high-speed reading and writing operation, and can guarantee the safety and reliability of data transmission. The electronic chip in electronic storage identifier also has good performance of preventing data tampering.

[0050] The anchor rod construction parameters include the number of the anchor rod, the preset installation length, the grouting amount, the installation time, the installation position and the installation angle, etc. The data reading and writing device writes the above construction parameters of each anchor rod in batches into the electronic storage identifier of the corresponding anchor rod and then reads them, so as to record the construction data such as the actual drilling position, the drilling angle and the grouting amount of each anchor rod, thereby the problems of inaccurate drilling position and drilling angle record of the anchor rod, and the construction quality problems such as insufficient grouting amount and insufficient grouting pressure can be found in time.

[0051] By reading the anchor rod construction parameters written and stored in the electronic storage identifier installed on all the anchor rods, and by comparing and analyzing the construction parameters and construction data with the construction plan (containing all the parameters of the anchor rods to be installed in advance), the actual installation quantity of the anchor rods can be detected, so as to obtain the detection result of the anchor rod quantity, and the construction quality problems of not drilling, less drilling and missing drilling in the construction process can be quickly detected and found. In combination with the detection result of the anchor rod length, the specific anchor rod with the construction quality problem can be quickly located, so as to timely improve the construction quality problem and eliminate the safety hazard in the subsequent process. Therefore, the effective supervision of the anchor rod installation at the construction site is realized, and the supervision efficiency is effectively improved.

[0052] In some embodiments, the anchor rod detection system further comprises an anchor rod construction management system, which is configured to receive the detection voltage value and the anchor rod construction parameter sent by the data reading and writing device and to visually display them.

[0053] Specifically, after reading the detection voltage value and the anchor rod construction parameter stored in the electronic storage identifier, the data reading and writing device sends the detection voltage value and the anchor rod construction parameter to the anchor rod construction management system for storage and visual display, so that the construction supervisor can timely check, understand and inquire the anchor rod detection result (installation length and quantity, etc.), and find the construction quality problem in time. Moreover, the anchor rod construction management system can alarm or send the detection result of the construction quality problem such as short length, not drilling, less drilling and missing drilling, inaccurate drilling position and drilling angle record, insufficient grouting amount and insufficient grouting pressure to the mobile terminal of the relevant construction supervisor, so as to timely remind the relevant construction supervisor to take relevant measures and efficiently and effectively supervise the construction process.

[0054] As shown in the detection process of the anchor rod detection system, Figure 2 including the following steps:

[0055] Step S110: The data reading and writing device 100 sends a detection instruction to the electronic storage identifier 200, which can be the reading of the second word in the reserved area of the electronic chip of the electronic storage identifier, etc.

[0056] Step S120: The electronic storage identifier 200 receives the detection instruction sent by the data reading and writing device 100, obtains the detection voltage value through the closed loop circuit formed by the electronic storage identifier 200, the detection line 301 and the resistance element 302 in series, stores the detection voltage value, and sends the detection voltage value to the data reading and writing device 100;

[0057] Step S130: The length detection result of the corresponding anchor rod is obtained based on the detection voltage value.

[0058] The specific process of anchor rod length judgment is as follows: if the detection voltage value is low, for example, less than 0.5V, it can be determined that the above-mentioned closed loop circuit is in a normal state or is considered to be in a short circuit state, that is, the loop impedance state is low impedance, for example, return code 0202 can be used to represent the state result, and further it can be explained that the actual installation length of the corresponding anchor rod is the same as the preset installation length, and the length of the anchor rod does not change in the construction process; if the detection voltage value is high, for example, greater than 0.5V, it can be determined that the above-mentioned closed loop circuit is in an abnormal state or is considered to be in an open circuit state, that is, the loop impedance state is high impedance, for example, return code 0000 can be used to represent the state result, and further it can be explained that the actual installation length of the corresponding anchor rod is different from the preset installation length, which means that there is a construction quality problem and hidden danger of shortening in length during the construction and installation of the anchor rod. It should be noted that when the anchor rod is artificially damaged, the detection line installed inside the anchor rod is also cut off and shortened, and the closed loop circuit formed by the electronic storage identifier, the cut detection line and the resistance element is in an open circuit and high impedance state.

[0059] For example, when the anchor rod is artificially damaged during construction, resulting in a situation of shortening in length, the anchor rod with a preset installation length of 3m changes to less than 3m after construction and installation, and the detection voltage value of the detected loop is high voltage at this time, because when the anchor rod is artificially damaged during construction, the 3m detection line (total length of 3m or slightly more than 3m) installed inside the anchor rod is also cut off and shortened, resulting in a closed loop circuit formed by the electronic storage identifier, the cut detection line and the resistance element in series, which is in an open circuit and high impedance state.

[0060] Step S140: The data reading and writing device 100 reads the anchor rod construction parameters written in the electronic storage identifier 200, which includes the number of anchor rods, the preset installation length, the grouting amount, the installation time, the installation position and the installation angle, etc.

[0061] Step S150: The number detection result of the anchor rod is obtained based on the read anchor rod construction parameters.

[0062] The specific process of the anchor rod quantity judgment is that: the construction data of the anchor rod number, the preset installation length, the grouting amount, the installation time, the installation position and the installation angle and the corresponding construction plan are compared and analyzed to obtain the detection result of the anchor rod quantity, so that the detection of the actual installation quantity of the anchor rod is realized, and the anchor rod which is not installed can be quickly located. The read anchor rod construction parameters and the anchor rod length detection result are combined, and the anchor rod with short length can be quickly located.

[0063] As shown in the detection process of the anchor rod detection system, Figure 3 the detection process includes the following steps:

[0064] Step S210: the data reading and writing device 100 sends a detection instruction to the electronic storage identifier 200, which can be the reading of the reserved area of the second word in the electronic chip of the electronic storage identifier;

[0065] Step S220: the electronic storage identifier 200 receives the detection instruction sent by the data reading and writing device 100, and transmits the detection instruction to the receiving port of the electronic tag 302 through the detection line 301;

[0066] Step S230: the electronic tag 302 obtains the detection voltage value and stores it according to the received detection instruction through the closed loop circuit formed by the electronic storage identifier 200, the detection line 301 and the electronic tag 302, and sends the detection voltage value to the data reading and writing device 100 through the antenna 3021 on the electronic tag 302;

[0067] Step S240: the length detection result of the corresponding anchor rod is obtained based on the detection voltage value;

[0068] The judgment process in step S240 is the same as the judgment process involved in step S130 in the detection process of the anchor rod detection system in the foregoing Figure 2 .

[0069] Step S250: the data reading and writing device 100 reads the anchor rod construction parameters written in the electronic storage identifier 200, which includes the number of anchor rods, the preset installation length, the grouting amount, the installation time, the installation position and the installation angle, etc.

[0070] Step S260: the quantity detection result of the anchor rod is obtained based on the read anchor rod construction parameters.

[0071] The judgment process in step S260 is the same as the judgment process involved in step S150 in the detection process of the anchor rod detection system in the foregoing Figure 2 .

[0072] In other embodiments, in the anchor detection device of the anchor detection system, the electronic tag 302 is an electronic chip without an antenna. The corresponding detection process is the same as Figure 3 The detection process of the anchor detection system shown is similar, except that step S230 is preceded by step S231:

[0073] Step S230: The electronic tag 302 obtains and stores a detection voltage value based on the received detection instruction through a closed circuit formed by the electronic storage identifier 200, the detection line 301, and the electronic tag 302 in series, and transmits the detection voltage value to the electronic storage identifier 200 via the detection line 301;

[0074] Step 231 : The electronic storage identifier 200 transmits the received detection voltage value to the data reading and writing device 100 via the antenna provided thereon.
