[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0035] In the production process of prefabricated components, for assembled buildings, the precise placement of embedded sleeves is crucial to ensure the stability of the structure and improve the efficiency of construction. However, the traditional positioning technology that relies on manpower to install embedded sleeves often has the technical problem of difficult to ensure the positioning accuracy of the embedded sleeves. Due to factors such as loose fixation and measurement errors, the position of the embedded sleeves in the prefabricated components often deviates. These problems may cause connection failures in the subsequent assembly stage and even affect the overall safety of the building.

[0036] In order to solve all or part of the technical problems in the above-mentioned related technologies, the embodiments of the present disclosure provide a positioning device for a pre-embedded sleeve in a prefabricated component. Figure 1 As shown, the positioning device of the embedded sleeve in the prefabricated component includes a positioning cylinder 1, a positioning assembly 2 and a pressure detection assembly 121. The positioning cylinder includes a cylinder body 11 and a plurality of pressure-bearing parts 12. A measurement mark 111 is provided on the side wall of the cylinder body close to the embedded sleeve, and the pressure-bearing part is located on the side of the cylinder body close to the embedded sleeve 4; the positioning assembly is provided at one end of the cylinder body close to the bottom of the embedded sleeve, and is used to detect the distance between the positioning cylinder and the bottom of the embedded sleeve; at least one pressure detection assembly is embedded in the pressure-bearing part, and is used to detect the pressure of the embedded sleeve on the positioning cylinder during the preparation of the prefabricated component 3; wherein, during the preparation of the prefabricated component, when the positioning cylinder is inserted into the embedded sleeve, the installation position of the embedded sleeve is positioned according to the measurement mark, the distance between the positioning cylinder and the bottom of the embedded sleeve. wherein, the isometric view of the positioning device of the embedded sleeve in the prefabricated component is shown in Figure 2 shown.

[0037] Specifically, the positioning cylinder can represent a component used to be inserted into the embedded sleeve to assist in positioning. The positioning cylinder can be composed of a cylinder body and a pressure-bearing part. The cylinder body is provided with a metric mark, which can help determine the depth of the positioning cylinder inserted into the embedded sleeve, thereby positioning the embedded sleeve. The pressure-bearing part is arranged on one side of the cylinder body, and is used to withstand the pressure from the prefabricated component. The positioning component can be used to measure the distance between the bottom end of the positioning cylinder and the bottom of the embedded sleeve, thereby determining the installation position of the embedded sleeve. The pressure detection component can represent a component embedded in the pressure-bearing part of the positioning cylinder, which is used to measure the pressure applied to the positioning cylinder by the embedded sleeve during the preparation process of the prefabricated component. By monitoring the pressure, it can be further ensured that the position of the embedded sleeve is accurate and will not move under the pouring of concrete or other external forces. Exemplarily, the cylinder body can be made of other materials with certain strength and durability, such as steel, aluminum alloy, engineering plastics, etc. The pressure-bearing part can be made of materials such as steel, cast iron, composite materials, etc. that can effectively transmit and disperse pressure. The positioning cylinder and the pressure-bearing part may be of an integral structure, or may be combined together through a connector or other means, such as threaded connection, welding, snap connection, pin or bolt connection, or other suitable connection means.

[0038] In some embodiments, the positioning component can be a photoelectric sensor, which uses the photoelectric principle. When the positioning tube contacts the bottom of the embedded sleeve, the photoelectric sensor sends a signal to detect the distance between the two. The positioning component can also be an ultrasonic sensor, which determines the distance between the positioning tube and the bottom of the embedded sleeve by emitting and receiving ultrasonic signals and calculating the time it takes for the ultrasonic wave to propagate between the positioning tube and the bottom of the embedded sleeve.

[0039] In some embodiments, the pressure detection component may be a pressure sensor, which converts the force applied to the pressure-bearing part of the positioning cylinder into a measurable electrical signal, thereby determining the magnitude of the pressure on the positioning cylinder. In addition, the pressure detection component may also be a strain gauge, which will deform when the pressure-bearing part is subjected to pressure, thereby changing its resistance value, and the pressure magnitude is determined by measuring the resistance change.

[0040] During the actual operation, first align the cylinder of the positioning cylinder with the opening of the embedded sleeve to ensure that the positioning cylinder can be smoothly inserted into the embedded sleeve, and confirm the measurement mark on the cylinder. Then, slowly insert the positioning cylinder into the embedded sleeve until the positioning component contacts the bottom of the embedded sleeve or the positioning cylinder has been fully inserted into the embedded sleeve. The positioning component detects the distance between the positioning cylinder and the bottom of the embedded sleeve and records it. By reading the measurement mark and combining the distance data provided by the positioning component, the exact position of the embedded sleeve in the prefabricated component can be determined. At the same time, during the preparation of the prefabricated component, the pressure detection component monitors the pressure of the embedded sleeve on the positioning cylinder in real time. If the pressure data shows that the position of the embedded sleeve is offset or the pressure is uneven, the pressure detection component can issue an early warning instruction. According to the position information and pressure data, the position of the embedded sleeve is fine-tuned to ensure that it is in the correct position and pressure state. After confirming that the embedded sleeve is accurately positioned and firmly fixed, the subsequent preparation process of the prefabricated component continues.

[0041] The positioning device for the embedded sleeve in the prefabricated component disclosed in the present invention, on the one hand, can accurately measure the position of the embedded sleeve through the combined action of the measurement mark and the positioning component, thereby ensuring the accurate installation of the embedded sleeve in the prefabricated component; on the other hand, the pressure detection component can monitor the pressure change of the embedded sleeve on the positioning tube in real time during the preparation of the prefabricated component, which is helpful to timely discover and adjust the potential embedded deviation of the embedded sleeve; on the other hand, the design of the pressure-bearing part enhances the structural stability of the positioning tube, ensuring that the stability and reliability of the positioning tube can be maintained even under a large pressure. Furthermore, the installation accuracy of the embedded sleeve in the prefabricated component is ensured at least to a certain extent, thereby improving the production quality and efficiency of the prefabricated component.

[0042] The various parts of the positioning device for the embedded sleeve in the above-mentioned prefabricated component are described in detail below.

[0043] In some embodiments, reference Figure 1 As shown, the positioning tube includes a dust cover 13, which covers the neck portion on the upper edge of the pressure-bearing portion. The positioning assembly is located inside the dust cover. Preferably, the dust cover adopts a bullet-shaped design.

[0044] The dust cover can refer to the neck portion covering the upper edge of the pressure-bearing portion, which fits tightly with the positioning tube and is used to protect the mechanism of the positioning assembly. Specifically, the dust cover can be used to prevent dust, concrete debris or other impurities from entering the positioning assembly when the positioning device enters the embedded sleeve, thereby preventing these impurities from affecting the normal operation of the positioning assembly and improving the positioning effect of the positioning assembly.

[0045] In some embodiments, reference Figure 1 As shown, the positioning cylinder can be a telescopic segmented structure, and a fixing position 112 is provided on one side of the cylinder body close to the embedded sleeve, and the fixing position is used to fix the positioning cylinder.

[0046] Among them, the fixed position can represent a component that can keep a certain segment or the whole of the positioning cylinder stable at a predetermined position to prevent it from moving unnecessarily during use. Exemplarily, the positioning cylinder can be designed as a plurality of interconnected segments, each of which can be telescoped within a certain range. The adjacent segments of the positioning cylinder are threadedly connected so that the cylinder body can be telescoped by rotation, such as the inner segment is designed as an external thread and the outer segment is designed as an internal thread; guide pins or sliding tracks can also be set inside the positioning cylinder to ensure that the segments can be aligned and stable during the telescopic process, and the guide pins or sliding tracks can pass through the segments of the cylinder body to limit the lateral movement of the positioning cylinder and only allow it to slide vertically. After the positioning cylinder is adjusted to the desired position, the positioning cylinder can be locked using the fixed position to prevent it from accidentally telescoped during use. Among them, the fixed position can fix the positioning cylinder by other suitable fixing components such as threads, buckles, pins, etc. The design of the telescopic segmented structure enables the positioning cylinder to adapt to embedded sleeves of different sizes and depths, thereby improving the versatility of the equipment. Through positioning, it can be ensured that the positioning cylinder is stable in a fixed position and will not move due to external forces, thereby ensuring the stability of the positioning cylinder during use.

[0047] In some embodiments, the positioning device of the embedded sleeve in the prefabricated component also includes a controller, which is electrically connected to the positioning component and the pressure detection component respectively, and is used to receive real-time position information and pressure information of the positioning device during the preparation of the prefabricated component.

[0048] The controller may represent a component for receiving and processing electrical signals from the positioning component and the pressure detection component and converting them into usable data information. The controller may sound an alarm when the pressure of the embedded sleeve on the positioning cylinder exceeds a preset threshold value to remind the timely correction of the problematic embedded sleeve. Exemplarily, the controller may also visualize the distance between the positioning cylinder and the bottom of the embedded sleeve and the pressure data of the embedded sleeve on the positioning cylinder, so that the operator can more conveniently monitor the positioning process.

[0049] In some embodiments, reference Figure 3 As shown, the positioning device of the embedded sleeve in the prefabricated component also includes a first signal light 5, which is arranged at one end of the positioning tube away from the bottom of the embedded sleeve. The first signal light is electrically connected to the positioning component. When the positioning component detects that the distance between the positioning tube and the bottom of the embedded sleeve is zero, the first signal light lights up.

[0050] The first signal light may represent a visual indicator, located at one end of the positioning tube away from the bottom of the embedded sleeve, and electrically connected to the positioning assembly. It may be used to light up when the positioning assembly detects that the distance between the positioning tube and the bottom of the embedded sleeve is zero, providing immediate visual feedback to the operator, indicating that the positioning tube has been correctly inserted into the embedded sleeve and has reached the required positioning depth, thereby preventing the operator from continuing to insert the positioning tube into the embedded sleeve, thereby causing damage to the positioning assembly on the positioning tube. The first signal light may use an LED light or other light-emitting element to ensure its reliability and visibility.

[0051] In some embodiments, reference Figure 3 As shown, the positioning device of the embedded sleeve in the prefabricated component also includes a second signal light 6, which is arranged at one end of the positioning tube away from the bottom of the embedded sleeve. The second signal light is electrically connected to the pressure detection component. When the pressure detection component detects that the pressure of the embedded sleeve on the positioning tube exceeds a preset pressure threshold, the second signal light lights up.

[0052] The second signal light is a visual indicator, located at the end of the positioning tube away from the bottom of the embedded sleeve, and is electrically connected to the pressure detection assembly. It can be used to light up when the pressure detection assembly detects that the pressure of the embedded sleeve on the positioning tube exceeds the preset pressure threshold, providing an immediate visual warning to the operator, indicating that a bias condition has occurred during the preparation of the prefabricated component or that the pressure tolerance threshold of the embedded sleeve has been exceeded, so that the operator can adjust the position of the embedded sleeve or reduce the pressure on the embedded sleeve, such as reducing the speed of applying concrete.

[0053] In some embodiments, reference Figure 1 As shown, the pressure-bearing portion includes a rubber pad 122, which is arranged on a side of the pressure detection component close to the embedded sleeve.

[0054] Among them, the rubber pad can represent an elastic gasket used to buffer and disperse the pressure of the embedded sleeve on the pressure detection component, while protecting the pressure detection component from direct impact or wear. Exemplarily, the rubber pad can be made of a material with elasticity and appropriate hardness, such as rubber, silicone or other polymer materials. The rubber pad can make the pressure applied by the embedded sleeve more evenly distributed to the pressure detection component, reduce local pressure concentration, and improve the accuracy of detection. As a protective layer, the rubber pad can prevent the pressure detection component from being damaged due to direct contact with the embedded sleeve, thereby extending the service life of the pressure detection component. By using rubber pads, measurement errors caused by uneven pressure can be reduced, and quality control in the preparation process of prefabricated components can be improved.

[0055] In some embodiments, reference Figure 1 As shown, the positioning device of the embedded sleeve in the prefabricated component also includes a base 7, which is arranged at one end of the positioning tube away from the bottom of the embedded sleeve, and the extension direction of the positioning tube is perpendicular to the plane where the base is located; wherein the base is used to limit the insertion depth of the positioning device by abutting against the prefabricated component when the positioning device is inserted into the embedded sleeve. Specifically, when the positioning device is inserted into the embedded sleeve, if the positioning tube is completely inserted into the embedded sleeve, the base of the horizontal structure abuts against the prefabricated component at the opening of the embedded sleeve, thereby preventing the positioning device from completely entering the embedded sleeve and being unable to be taken out.

[0056] In some embodiments, reference Figure 1 As shown, the pressure-bearing part further includes at least two distance sensors. The distance sensor 123 is embedded in the pressure-bearing part and is used to measure the distance between the pressure-bearing part and the embedded sleeve.

[0057] Specifically, generally speaking, the embedded sleeve in the prefabricated component needs to be kept vertical, that is, the extension direction of the embedded sleeve needs to be perpendicular to the plane of the prefabricated component where the opening of the embedded sleeve is located. When the base is in contact with the prefabricated component, multiple sets of distance data between the pressure-bearing part and the embedded sleeve are obtained through distance sensors arranged at different positions in the pressure-bearing part. When the deviation of these distance data does not exceed the set value, it indicates that the installation direction of the embedded sleeve meets the requirements.

[0058] In some embodiments, the connection part between the positioning tube and the base can be a quick-release structure, so that the operator can replace the positioning tube, wherein the positioning tube can have different diameters to achieve accurate measurement of embedded sleeves of different specifications. Exemplarily, the bottom of the positioning tube can be threadedly connected to the base, such as the bottom of the positioning tube is designed as an internal thread structure, the top of the base is designed as an external thread structure, or the bottom of the positioning tube is designed as an external thread structure, the top of the base is designed as an internal thread structure, and the two are connected by threaded engagement. The bottom of the positioning tube and the top of the base can be a snap-on structure, and the two are connected by snaps. The positioning tube and the base can also be magnetically connected, such as the bottom of the positioning tube and the top of the base are respectively installed with permanent magnets, and the two are connected by magnetic attraction. The positioning tube and the base can also be quick-plug-in connected, the bottom of the positioning tube is provided with a plug-in, and the base is provided with a jack corresponding to the plug-in, and the plug-in is inserted into the jack, thereby realizing the quick-plug-in connection between the positioning tube and the base.

[0059] In some embodiments, a pin may be provided on one side of the positioning cylinder close to the base, and the pin is electrically connected to the pressure detection component, the distance sensor and the positioning component. A socket corresponding to the pin is provided on the base, and the socket is electrically connected to the controller for transmitting distance information and pressure information to the controller. When the positioning cylinder and the base are connected in a quick-plug manner, the pin is inserted into the socket as the positioning cylinder and the base are docked, and the electrical connection is completed at the same time. Among them, the number of pins and sockets is the same and the two are arranged correspondingly. The pins can be PIN pins, and the pins can be arranged horizontally, vertically, or in multiple rows in parallel. This example embodiment does not specifically limit the arrangement of the pins.

[0060] The disclosed embodiment also provides another positioning device for the embedded sleeve in the prefabricated component, referring to Figure 4 As shown in FIG. 1 , the positioning tube 1 of the positioning device can slide vertically along the connecting hole 8 on the base 7. Specifically, the base is provided with a connecting hole for the positioning tube to slide vertically, and a roller or a ball can be provided on the contact surface between the connecting hole and the positioning tube so that the positioning tube can slide smoothly along the base. The bottom view of the positioning device of the embedded sleeve in the prefabricated component is shown in FIG. Figure 5 As shown, reference Figure 5, the pressure-bearing portion 12 on the positioning cylinder contacts the inner wall of the connecting hole. A measurement mark 111 is provided on the side wall of the cylinder body of the positioning cylinder close to the embedded sleeve. In addition, a buckle assembly for limiting the movement of the positioning cylinder can also be provided on the base. When the positioning cylinder moves vertically, the buckle assembly opens, and when the positioning cylinder moves to a preset position, the buckle assembly closes. The positioning cylinder is fixed by the buckle assembly to prevent it from moving during the measurement process. When measuring, align the cylinder body of the positioning cylinder with the opening of the embedded sleeve to ensure that the positioning cylinder can be smoothly inserted into the embedded sleeve, and at the same time place the base at the opening of the embedded sleeve to contact the prefabricated component. The operator slides the positioning cylinder into the embedded sleeve, and stops inserting when the positioning cylinder contacts the bottom of the embedded sleeve or cannot continue to move into the embedded sleeve due to resistance. Then, the scale value on the measurement mark corresponding to the contact surface between the base and the prefabricated component is observed, and the embedded depth of the embedded sleeve is determined based on the scale value, so as to position the embedded sleeve in the prefabricated component.

[0061] The positioning device for the embedded sleeve in the prefabricated component disclosed in the present invention, on the one hand, can accurately measure the position of the embedded sleeve through the combined action of the measurement mark and the positioning component, thereby ensuring the accurate installation of the embedded sleeve in the prefabricated component; on the other hand, the pressure detection component can monitor the pressure change of the embedded sleeve on the positioning tube in real time during the preparation of the prefabricated component, which is helpful to timely discover and adjust the potential embedded deviation of the embedded sleeve; on the other hand, the design of the pressure-bearing part enhances the structural stability of the positioning tube, ensuring that the stability and reliability of the positioning tube can be maintained even under a large pressure. Furthermore, the installation accuracy of the embedded sleeve in the prefabricated component is ensured at least to a certain extent, thereby improving the production quality and efficiency of the prefabricated component.

[0062] In addition, the design of the dust cover can prevent dust from entering the positioning component, reducing maintenance costs. The introduction of a controller to monitor the position information and pressure information of the positioning device in real time helps to reduce errors that may be caused by manual operation. By setting the first signal light and the second signal light, an alarm can be issued in time when the embedded sleeve deviates from the predetermined position or the pressure is abnormal, thereby improving the installation accuracy and efficiency of the embedded sleeve. The retractable segmented design of the positioning cylinder enables the device to adapt to embedded sleeves of different sizes and depths, enhancing the flexibility and scope of application of the positioning device. By adding a rubber pad to the pressure-bearing part, the pressure detection component can be protected from direct impact or wear, thereby extending the service life of the equipment. The design of the base not only helps to limit the insertion depth of the positioning device, but also facilitates the operator to quickly complete the positioning work.

[0063] The present disclosure also provides a method for positioning a pre-embedded sleeve in a prefabricated component, which is applied to, with reference to Figure 6 As shown, the method for positioning the embedded sleeve in the prefabricated component specifically includes the following steps:

[0064] Step S610: During the preparation of the prefabricated component, the positioning tube is inserted into the embedded sleeve.

[0065] Step S620: using the positioning assembly to detect the distance between the positioning tube and the bottom of the embedded sleeve.

[0066] Step S630, using a pressure detection assembly to detect the pressure of the embedded sleeve on the positioning tube.

[0067] Step S640, locating the installation position of the embedded sleeve according to the measurement mark on the positioning tube and the distance between the positioning tube and the bottom of the embedded sleeve.

[0068] Specifically, during the preparation of the prefabricated component, the positioning tube is inserted along the central axis direction of the embedded sleeve. The positioning component on the positioning tube uses ultrasonic, laser or other non-contact distance measurement technology to measure the distance between the bottom of the positioning tube and the bottom of the embedded sleeve. At the same time, the pressure detection component on the positioning tube is able to sense and record the pressure of the embedded sleeve on the positioning tube. When the pressure exceeds the preset pressure threshold, it indicates that there is a bias in the embedded sleeve and the position needs to be adjusted. However, based on the measurement mark on the positioning tube and the distance between the positioning tube and the bottom of the embedded sleeve, the installation depth of the embedded sleeve can be determined, thereby determining whether the installation position of the embedded sleeve meets the requirements.

[0069] It should be understood that the present disclosure does not limit its application to the detailed structure and arrangement of the components proposed in the present disclosure. The present disclosure can have other embodiments and can be implemented and executed in a variety of ways. The aforementioned variations and modifications fall within the scope of the present disclosure. It should be understood that the present disclosure and the limited present disclosure extend to all alternative combinations of two or more individual features mentioned or evident in the text and / or the drawings. All of these different combinations constitute multiple alternative aspects of the present disclosure.
