Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection systems, in particular to a wireless cement pole detection system. BACKGROUND

[0002] The cement pole is mainly composed of steel bars and concrete, so it is also called reinforced concrete cement pole. It is mainly used as a line support in the power, communication, railway and oil industries. It is one of the most basic and indispensable network materials in network construction. Any quality defects of the cement pole will pose a serious threat to the safe operation of the power grid. However, the production technology of such materials has a low threshold, and there are many manufacturers and complex supply channels. Moreover, the supply method is usually to send the goods directly to the construction site for installation.

[0003] In order to strictly control the quality of network materials and prevent unqualified products from entering the network, our industry requires that cement pole materials need to be sampled and inspected, and the material department is responsible for the whole sampling and inspection process. Sampling is carried out at the construction site, the sample is sealed, vehicles are arranged, and the sample is transported to a professional detection agency for detection.

[0004] The existing detection method has the following problems: first, the cement pole is easily damaged during transportation; second, after the cement pole is transported to the detection agency, the cement pole needs to be placed on the detection device one by one for detection, and after detection, the detected cement pole needs to be removed from the detection device and a new cement pole to be detected is placed on it, and the detection process starts again, which is low in detection efficiency. SUMMARY

[0005] In order to solve the problems of easy damage and low detection efficiency of the cement pole in the prior art, the present application provides a wireless cement pole detection system, which is not easily damaged and has high detection efficiency.

[0006] To achieve the above purpose, the present application adopts the following technical scheme:

[0007] A wireless cement pole detection system, comprising a base, a first rotating plate is arranged on the upper side of the base, one side of the first rotating plate is rotatably connected with the base and is provided with a first rotating axis extending horizontally, the base is provided with a first driving device for driving the first rotating plate to rotate around the first rotating axis, a support for mounting a plurality of cement poles is detachably connected to the upper side of the first rotating plate, a telescopic beam is arranged on the upper side of the base, the telescopic beam is arranged on the side of the first rotating plate close to the first rotating axis, one end of the telescopic beam is rotatably connected with the base, a second driving device for rotating the telescopic beam is arranged on the base, a reversing wheel is arranged at the other end of the telescopic beam, a winch is arranged on the telescopic beam, the winch is provided with a steel cable for connecting with the cement pole, the wireless cement pole detection system further comprises a mounting frame and a plurality of displacement sensors arranged in sequence on the mounting frame in the vertical direction.

[0008] With the above settings, the cement poles are not easily damaged and the detection efficiency is high. Specifically, the brackets are pre-placed at the construction site. When the cement poles are transported to the construction site, first install the cement poles on the brackets. Specifically, place the bottom plate flat on the ground, and then use the crane at the construction site to hoist multiple cement poles onto the brackets one by one, and fix the cement poles on the brackets. The cement poles are parallel to each other. One end of the cement pole is protected by the bracket, and the other end is outside the bracket and the end of the cement pole is wrapped with a nylon rope or cloth strip to prevent the part of the cement pole outside the bracket from being damaged. Then transport the cement poles together with the brackets to the testing agency. Then remove the nylon rope or cloth strip from the cement poles, and hoist the brackets and the cement poles onto the first rotating plate with the crane of the testing agency, and fix the brackets on the first rotating plate with bolts. At this time, the axis of the cement pole is parallel to the axis of the telescopic beam, and the axis of the cement pole is parallel to the first rotation axis. Under the action of the first driving device, the first rotating plate rotates 90 degrees. At this time, the cement poles are arranged from top to bottom in sequence, and the axis of the cement pole extends horizontally. The cement pole is located on the side of the first rotating plate close to the telescopic beam. At this time, the reversing wheel is basically located under the cement pole. The end of the cement pole outside the bracket is the loading end and is sleeved with a rope sleeve. Then, under the action of the second driving device, the telescopic beam rotates upward and makes the telescopic beam basically face the loading end of one of the cement poles. Then the telescopic beam extends and makes the reversing wheel move to the side of the corresponding loading end away from the first rotating plate. Then the steel cable is connected to the rope sleeve at the corresponding loading end through the reversing wheel. The telescopic beam refers to the boom of an existing crane. Then install the mounting frame on the base. The mounting frame is located on the side of the loading end away from the telescopic beam. Install multiple displacement sensors on the mounting frame. The displacement sensors are arranged from top to bottom in sequence and correspond to the positions of the loading ends of the cement poles one by one. The displacement sensors can refer to existing linear displacement sensors with wireless transmission functions. During use, place the linear displacement sensor against the side of the loading end away from the telescopic beam to measure the deflection of the loading end of the cement pole after being stressed. The displacement sensors can transmit the measured deflection data of the loading end of the cement pole to the background in real time wirelessly, which is convenient for the testers to understand the test situation. During the test, the winch winds the steel cable. The steel cable pulls the cement pole through the rope sleeve and applies a force perpendicular to the axis of the cement pole to make the cement pole bend. A tension sensor is arranged between the steel cable and the rope sleeve. The tension sensor is connected to the background, and the background can obtain the tension received at the end of the cement pole in real time. The greater the tension, the greater the deflection of the loading end. The winch gradually increases the power, so that the tension received at the loading end gradually increases. When the force received at the loading end increases to a preset value, it can be determined whether the tested cement pole is qualified according to the deflection of the loading end. Specifically, when the deflection is greater than the threshold, the cement pole is unqualified; otherwise, it is qualified.After testing one cement pole, the steel cable and rope loop are disconnected. Then, the second drive device rotates the telescopic beam upwards or downwards by an angle, so that the telescopic beam faces the loading end of another cement pole to be tested. The telescopic beam then extends or shortens, causing the reversing wheel to move to the side of the loading end of the other cement pole away from the first rotating plate. The steel cable is then connected to the rope loop of the corresponding loading end. The winch then runs and loads the loading end. The same steps are used to test all cement poles on the support. This process can be repeated to test all cement poles on the support. Unlike traditional testing methods, there is no need to repeatedly load and unload cement poles, which greatly improves the testing efficiency.

[0009] Furthermore, the support includes a base plate, on one side of which are fixedly connected several parallel limiting plates, forming a receiving space for accommodating the cement rod. The extending direction of the receiving space is consistent with the extending direction of the first rotation axis. Each receiving space is provided with a clearance groove, which is set on the base plate. The extending direction of the clearance groove is consistent with the extending direction of the limiting plate. One end of the clearance groove is fixedly connected to a first support block for supporting the cement rod, and the other end of the clearance groove is fixedly connected to a limiting block for supporting the cement rod. The middle of each limiting plate is detachably connected to a second support block for limiting the cement rod on the first support block and the limiting block. A rotating roller is provided at the end of the receiving space near the first support block, and the rotating roller is rotatably connected between the limiting plates.

[0010] Furthermore, the base plate and the limiting plate are perpendicular, the axis of the rotating roller is parallel to the base plate, and the axis of the rotating roller is perpendicular to the limiting plate.

[0011] Furthermore, a first groove for fitting with the cement rod is provided on one side of the first support block, and a second groove for fitting with the cement rod is provided on one side of the second support block. When the cement rod fits into the first groove and the cement rod fits into the second groove, the cement rod and the limiting block are separated.

[0012] With the above setup, when installing the cement pole at the construction site, first remove the second support block from the limiting plate, and then use a crane to place one end of the cement pole into the receiving space. Specifically, the cement pole is placed on the first support block and the limiting block, with the end of the cement pole close to the rotating roller. Then, use bolts to install the second support block on the limiting plate. At this time, the first support block and the limiting block are located on the lower side of the cement pole, and the second support block is located on the upper side of the cement pole. At this time, the lower side of the cement pole is located in the first groove, and the upper side of the cement pole is located in the second groove. Thus, the cement pole can be stably positioned between the first support block, the limiting block, and the second support block. During transportation, the end of the cement pole is not easy to shake in the receiving space, has good stability, and is not easily damaged.

[0013] During testing, the bracket and cement poles are hoisted onto the first rotating plate using a crane from the testing mechanism. Specifically, the base plate is attached to the first rotating plate and fixed with bolts. At this point, the axis of the cement pole is parallel to the axis of the telescopic beam, and the axis of the cement pole is parallel to the first rotating axis. The extension direction of the limiting plate is consistent with the axis of the cement pole. Under the action of the first driving device, the first rotating plate rotates 90 degrees. At this time, the cement poles are arranged sequentially from top to bottom, with their axes extending horizontally. Under the action of gravity, the cement poles are pressed against the limiting plate, which is horizontal. One end of the cement pole abuts against the rotating roller, thereby achieving the positioning of the cement pole. At this point, the axis of the rotating roller extends vertically, and the other end of the cement rod is suspended in the air. The cement rod is located on the side of the first rotating plate near the telescopic beam. At this time, the reversing wheel is basically located on the lower side of the cement rod. The end of the cement rod outside the support is the loading end and is fitted with a rope loop. Then, under the action of the second drive device, the telescopic beam rotates upward and makes the telescopic beam basically face the loading end of one of the cement rods. Then the telescopic beam extends and makes the reversing wheel move to the side of the corresponding loading end away from the first rotating plate. Then the steel cable is connected to the rope loop of the corresponding loading end through the reversing wheel. The telescopic beam is modeled after the boom of an existing crane. Then, the mounting frame is installed on the base, and the mounting frame is located on the loading end away from the telescopic beam. On one side of the beam, multiple displacement sensors are installed on a mounting frame. The sensors are arranged sequentially from top to bottom, each corresponding to a specific loading end of the concrete pole. These sensors can be similar to existing linear displacement sensors with wireless transmission capabilities. During use, the linear displacement sensor is placed against the side of the loading end furthest from the telescopic beam to measure the deflection of the concrete pole under load. The displacement sensor can transmit the measured deflection data wirelessly to the backend in real time, allowing testing personnel to monitor the test results. During testing, a winch winds a steel cable, which pulls the concrete pole through a rope loop, applying a force perpendicular to the pole's axis. The direction of the force exerted by the steel cable on the cement pole is parallel to that of the limiting plate, thereby reducing the influence of the limiting plate on the deflection of the cement pole. Furthermore, a graphite layer can be set on the upper side of the limiting plate to reduce the friction between the cement pole and the limiting block, thereby reducing the influence of friction on deflection and improving the accuracy of detection. When the steel cable loads the cement pole, the first support block and the second support block squeeze the cement pole. Under the action of the steel cable, the first support block and the second support block, the cement pole bends, and the limiting block and the cement pole separate, thereby preventing the limiting block from affecting the deformation of the cement pole. When the cement pole deflects at the end near the rotating roller, the rotating roller rotates, reducing the influence of the rotating roller on the deformation of the cement pole.A tension sensor is installed between the steel cable and the rope loop, and the sensor is connected to a backend system. The backend system can obtain the tension force on the end of the cement pole in real time. The greater the tension force, the greater the deflection at the loading end. The winch gradually increases its power, thus gradually increasing the tension force on the loading end. When the force on the loading end increases to a preset value, the deflection at the loading end determines whether the tested cement pole is qualified. Specifically, if the deflection is greater than a threshold, the cement pole is unqualified; otherwise, it is qualified. After testing one cement pole, the steel cable and rope loop are disconnected. Then, the second drive device rotates the telescopic beam upwards or downwards by an angle, so that the telescopic beam faces the loading end of another cement pole to be tested. The telescopic beam then extends or shortens, causing the reversing wheel to move to the side of the loading end of another cement pole away from the first rotating plate, and the steel cable is connected to the rope loop of the corresponding loading end. Then, the winch runs and loads the loading end. The same steps are used to test cement poles. This process can be repeated to test all cement poles on the support. In this process, it is not necessary to repeatedly load and unload cement poles as in traditional testing methods, thus greatly improving testing efficiency.

[0014] Furthermore, a second rotating plate is provided on the upper side of the first rotating plate. One side of the second rotating plate is rotatably connected to the first rotating plate and is provided with a second rotating axis perpendicular to the first rotating axis. The second rotating axis extends horizontally. The first rotating plate is provided with a third driving device for driving the second rotating plate to rotate around the second rotating axis. The second rotating axis is provided on the side of the bracket near the rotating roller.

[0015] With the above setup, all cement poles on the support can be quickly positioned. Specifically, initially, the second rotating plate abuts against the upper side of the flip plate and the positioning block, at which point the second rotating plate is horizontal. The support and cement poles are then hoisted onto the second rotating plate, and the base plate is fixed to the second rotating plate with bolts. At this point, the end of the cement pole away from the rotating roller faces away from the flip plate, and the second rotation axis is perpendicular to the axis of the cement pole. Under the action of the third drive device, the end of the second rotating plate away from the flip plate rotates upward at an angle. Under the action of gravity, the cement pole slides downward and abuts against the corresponding rotating roller, automatically achieving the positioning of the cement pole. Then, under the action of the third drive device, the second rotating plate rotates around the second rotation axis and abuts against the positioning block again, and the second rotating plate returns to its original position. The first rotating plate rotates 90 degrees around the first rotating axis under the action of the first driving device. The first rotating plate drives the second rotating plate to rotate together. At this time, both the first and second rotating plates extend vertically. Cement rods are set from top to bottom, with their axes extending horizontally. Under the action of gravity, the cement rods are pressed against the limiting plate, which is horizontal. One end of the cement rod abuts against the rotating roller, thus positioning the cement rod. At this time, the axis of the rotating roller extends vertically, and the other end of the cement rod is suspended in the air. The cement rod is located on the side of the first rotating plate near the telescopic beam. At this time, the reversing wheel is basically located on the lower side of the cement rod. The end of the cement rod outside the bracket is the loading end and is fitted with a rope loop. Then, under the action of the second driving device, the telescopic beam moves towards... The telescopic beam rotates upwards, aligning itself approximately with the loading end of one of the concrete poles. It then extends, causing the reversing wheel to move to the side of the corresponding loading end away from the first rotating plate. A steel cable is then connected to the rope loop at the corresponding loading end via the reversing wheel. The telescopic beam is modeled after the boom of an existing crane. A mounting frame is then installed on the base, located on the side of the loading end away from the telescopic beam. Multiple displacement sensors are installed on the mounting frame, arranged sequentially from top to bottom, corresponding one-to-one with the loading end position of the concrete pole. These displacement sensors can be modeled after existing linear displacement sensors with wireless transmission capabilities. In use, the linear displacement sensor is placed against the side of the loading end away from the telescopic beam to measure the deflection of the concrete pole after being subjected to force. The sensor can wirelessly transmit the measured deflection data of the cement pole's loaded end to the backend in real time, allowing testing personnel to understand the test results. During testing, a winch winds a steel cable, which pulls the cement pole through a rope loop, applying a force perpendicular to the pole's axis and causing it to bend. The direction of the force exerted by the steel cable on the cement pole is parallel to the limiting plate, thus reducing the influence of the limiting plate on the cement pole's deflection. Furthermore, a graphite layer can be placed on the upper side of the limiting plate to reduce the friction between the cement pole and the limiting block, thereby reducing the impact of friction on deflection and improving the accuracy of the test. A clearance groove is used to avoid the cement pole, preventing the base plate from affecting the cement pole's deformation. When the steel cable loads the cement pole, the first and second support blocks compress the cement pole.Under the action of the steel cable, the first support block, and the second support block, the cement pole bends. The first groove fits into the cement pole, thereby reducing the pressure of the first support block on the cement pole and preventing it from crushing the cement pole and affecting the detection. The second groove fits into the cement pole, thereby reducing the pressure of the second support block on the cement pole and preventing it from crushing the cement pole and affecting the detection. The limiting block disengages from the cement pole, thereby preventing it from affecting the deformation of the cement pole. When the end of the cement pole near the rotating roller deflects, the rotating roller rotates, reducing the influence of the rotating roller on the deformation of the cement pole. A tension sensor is installed between the steel cable and the rope loop, and the tension sensor is connected to the backend. The backend can obtain the tension force on the end of the cement pole in real time. The greater the tension force, the greater the deflection at the loading end. The winch gradually increases the power, thereby gradually increasing the tension force on the loading end. When the force on the loading end increases to a preset value, the deflection at the loading end can be used to determine whether the detected cement pole is qualified. Specifically, if the deflection is greater than the threshold, the cement pole is unqualified; otherwise, it is qualified. After testing one cement pole, the steel cable and rope loop are disconnected. Then, the second drive device rotates the beam upwards or downwards by an angle, so that the telescopic beam faces the loading end of another cement pole to be tested. The telescopic beam then extends or shortens, causing the reversing wheel to move to the side of the loading end of the other cement pole away from the first rotating plate. The steel cable is then connected to the rope loop of the corresponding loading end. The winch then runs and loads the loading end. The same steps are used to test all cement poles on the support. This process eliminates the need for repeated loading and unloading of cement poles as in traditional testing methods, greatly improving testing efficiency.

[0016] Furthermore, the base includes an upper steel plate and a lower steel plate disposed on the lower side of the upper steel plate. The upper steel plate and the lower steel plate are fixedly connected by a connecting plate. The upper steel plate is provided with a through hole. The first driving device includes a first hydraulic cylinder disposed between the first rotating plate and the lower steel plate. One end of the first hydraulic cylinder is rotatably connected to the lower steel plate, and the other end of the first hydraulic cylinder is rotatably connected to the first rotating plate.

[0017] With the above settings, the first rotating plate can rotate around the first rotating axis. Specifically, when the first oil cylinder extends, the first rotating plate rotates upward; conversely, when the first oil cylinder shortens, the second rotating plate rotates downward.

[0018] Furthermore, one side of the first rotating plate extends upward to form a flap, the flap and the second rotating plate are rotatably connected, a positioning block is fixedly connected to the side of the first rotating plate away from the flap, the positioning block abuts against the second rotating plate, and the third driving device includes a second oil cylinder disposed between the first rotating plate and the second rotating plate, one end of the second oil cylinder is rotatably connected to the first rotating plate, and the other end of the second oil cylinder is rotatably connected to the second rotating plate.

[0019] With the above settings, the second rotating plate can rotate around the second rotating axis. When the second oil cylinder extends, the second rotating plate drives the bracket to rotate upward. When the second oil cylinder shortens, the second rotating plate drives the bracket to rotate downward.

[0020] Furthermore, the second drive unit is configured as a geared motor. Attached Figure Description

[0036] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0037] See Figures 1 to 15 A wireless cement pole detection system includes a base 11, a first rotating plate 12 disposed on the upper side of the base 11, one side of the first rotating plate 12 being rotatably connected to the base 11 and having a first rotating axis 101 extending horizontally, the base 11 being provided with a first driving device 13 for driving the first rotating plate 12 to rotate around the first rotating axis 101, a bracket 14 for mounting multiple cement poles 21 being detachably connected to the upper side of the first rotating plate 12, and a telescopic beam 111 disposed on the upper side of the base 11. The rotating plate 12 is located on one side near the first rotating axis 101. One end of the telescopic beam 111 is rotatably connected to the base 11. The base 11 is provided with a second driving device 112 for rotating the telescopic beam 111. The other end of the telescopic beam 111 is provided with a reversing wheel 1111. The telescopic beam 111 is provided with a winch 1112. The winch 1112 is provided with a steel cable 1113 for connecting with the cement pole 21. The wireless cement pole detection system also includes a mounting frame 15 and a number of displacement sensors 16 arranged vertically on the mounting frame 15.

[0038] With the above setup, the cement pole 21 is not easily damaged and the inspection efficiency is high. Specifically, the bracket 14 is placed in advance at the construction site. When the cement pole 21 is transported to the construction site, it is first installed on the bracket 14. Specifically, the base plate 141 is placed flat on the ground, and then a crane at the construction site is used to hoist multiple cement poles 21 onto the bracket 14 one after another, and the cement poles 21 are fixed to the bracket 14. The cement poles 21 are parallel to each other, one end of the cement pole 21 is protected by the bracket 14, and the other end is outside the bracket 14 and is wrapped with nylon rope or cloth strips to prevent the cement pole 21 from being damaged. If the portion of the concrete pole 21 located outside the support 14 is damaged, then the concrete pole 21, along with the support 14, is transported to the testing facility. The nylon rope or cloth strips are then removed from the concrete pole 21, and the support 14 and concrete pole 21 are hoisted onto the first rotating plate 12 using a crane from the testing facility. The support 14 is then bolted to the first rotating plate 12. At this point, the axis of the concrete pole 21 is parallel to the axis of the telescopic beam 111, and the axis of the concrete pole 21 is parallel to the first rotating axis 101. Under the action of the first driving device 13, the first rotating plate 12 rotates ninety degrees. (See [reference]) Figure 13At this point, the cement poles 21 are arranged sequentially from top to bottom, with their axes extending horizontally. The cement poles 21 are located on the side of the first rotating plate 12 closest to the telescopic beam 111. The reversing wheel 1111 is approximately located below the cement pole 21. The end of the cement pole 21 outside the bracket 14 is the loading end 211 and is fitted with a rope loop 31. Then, under the action of the second driving device 112, the telescopic beam 111 rotates upwards, causing it to face approximately towards the loading end 211 of one of the cement poles 21. The telescopic beam 111 then extends, causing the reversing wheel 1111 to... 11 moves to the side of the corresponding loading end 211 away from the first rotating plate 12, and then the steel cable 1113 is connected to the rope loop 31 of the corresponding loading end 211 through the reversing wheel 1111. The telescopic beam 111 is referenced to the boom of an existing crane. Then, the mounting frame 15 is installed on the base 11. The mounting frame 15 is located on the side of the loading end 211 away from the telescopic beam 111. Multiple displacement sensors 16 are installed on the mounting frame 15. The displacement sensors 16 are arranged sequentially from top to bottom and correspond one-to-one with the position of the loading end 211 of the cement pole 21. The displacement sensors 16 can... Referring to the existing linear displacement sensor 16 with wireless transmission function, during use, the linear displacement sensor 16 is placed against the side of the telescopic beam 111 away from the loading end 211 to measure the deflection of the loading end 211 of the cement pole 21 after being subjected to force. The displacement sensor 16 can transmit the measured deflection data of the loading end 211 of the cement pole 21 to the back-end wirelessly in real time, which is convenient for the testing personnel to understand the test situation. During the test, the winch 1112 winds the steel cable 1113, and the steel cable 1113 pulls the cement pole 21 through the rope loop 31, and the cement pole 21 is subjected to force. A force perpendicular to the axis of the cement pole 21 is applied to the pole 21, causing it to bend. A tension sensor is installed between the steel cable 1113 and the rope loop 31. The tension sensor is connected to a backend system, which can obtain the tension force on the end of the cement pole 21 in real time. The greater the tension force, the greater the deflection of the loading end 211. The winch 1112 gradually increases its power, thereby gradually increasing the tension force on the loading end 211. When the force on the loading end 211 increases to a preset value, the deflection of the loading end 211 can be used to determine whether the tested cement pole 21 is qualified. See [link to relevant documentation]. Figure 14Specifically, when the deflection exceeds a threshold, the cement pole 21 is considered unqualified; otherwise, it is considered qualified. After testing one cement pole 21, the steel cable 1113 and the rope loop 31 are disconnected. Then, the second drive device 112 rotates the pole upwards or downwards by an angle, causing the telescopic beam 111 to face the loading end 211 of another cement pole 21 to be tested. The telescopic beam 111 then extends or shortens, causing the reversing wheel 1111 to move to the side of the loading end 211 of another cement pole 21 away from the first rotating plate 12. The steel cable 1113 is then connected to the rope loop 31 of the corresponding loading end 211. The winch 1112 then runs and loads the loading end 211. The same steps are used to test the cement poles 21. This process can be repeated to test all the cement poles 21 on the bracket 14. In this process, it is not necessary to repeatedly load and unload the cement poles 21 as in traditional testing methods, thus greatly improving the testing efficiency.

[0039] In one implementation, the bracket 14 includes a base plate 141. A plurality of parallel limiting plates 142 are fixedly connected to one side of the base plate 141. The limiting plates 142 form a receiving space for accommodating the cement rod 21. The extending direction of the receiving space is consistent with the extending direction of the first rotation axis 101. Each receiving space is provided with a relief groove 143. The relief groove 143 is provided on the base plate 141. The extending direction of the relief groove 143 is consistent with the extending direction of the limiting plate 142. A first support block 144 for supporting the cement rod 21 is fixedly connected to one end of the relief groove 143. A limiting block 145 for supporting the cement rod 21 is fixedly connected to the other end of the relief groove 143. A second support block 146 for limiting the cement rod 21 on the first support block 144 and the limiting block 145 is detachably connected to the middle of each limiting plate 142. A rotating roller 147 is provided at the end of the receiving space near the first support block 144. The rotating roller 147 is rotatably connected between the limiting plates 142.

[0040] In one implementation, the base plate 141 and the limiting plate 142 are perpendicular, the axis of the rotating roller 147 is parallel to the base plate 141, and the axis of the rotating roller 147 is perpendicular to the limiting plate 142.

[0041] As one implementation, a first groove 1441 for fitting with the cement rod 21 is provided on one side of the first support block 144, and a second groove 1461 for fitting with the cement rod 21 is provided on one side of the second support block 146. When the cement rod 21 fits with the first groove 1441 and the cement rod 21 fits with the second groove 1461, the cement rod 21 and the limiting block 145 are separated.

[0042] With the above setup, when installing the cement pole 21 at the construction site, first remove the second support block 146 from the limiting plate 142, then use a crane to place one end of the cement pole 21 into the receiving space. Specifically, the cement pole 21 is placed on the first support block 144 and the limiting block 145, with the end of the cement pole 21 close to the rotating roller 147. Then, use bolts to install the second support block 146 onto the limiting plate 142. At this time, the first support block 144 and the limiting block 145 are located on the lower side of the cement pole 21, and the second support block 146 is located on the upper side of the cement pole 21. See [link to documentation]. Figure 9 At this time, the lower side of the cement rod 21 is located in the first groove 1441, and the upper side of the cement rod 21 is located in the second groove 1461. Thus, the cement rod 21 can be stably positioned between the first support block 144, the limiting block 145, and the second support block 146. During transportation, the end of the cement rod 21 is not easy to shake in the accommodating space, and it has good stability and is not easily damaged.

[0043] During testing, the bracket 14 and cement pole 21 are hoisted onto the first rotating plate 12 using a crane from the testing organization. Specifically, the base plate 141 is attached to the first rotating plate 12 and fixed to the first rotating plate 12 with bolts. See [link to documentation]. Figure 12 At this time, the axis of the cement pole 21 is parallel to the axis of the telescopic beam 111, the axis of the cement pole 21 is parallel to the first rotation axis 101, and the extension direction of the limiting plate 142 is consistent with the axial direction of the cement pole 21. Under the action of the first driving device 13, the first rotating plate 12 rotates ninety degrees. (See below) Figure 13At this point, cement rods 21 are arranged sequentially from top to bottom, with their axes extending horizontally. Under the influence of gravity, the cement rods 21 are pressed against the limiting plate 142, which is horizontal. One end of the cement rod 21 abuts against the rotating roller 147, thus positioning the cement rod 21. At this point, the axis of the rotating roller 147 extends vertically, and the other end of the cement rod 21 is suspended in the air. The cement rod 21 is located on the side of the first rotating plate 12 near the telescopic beam 111. At this point, the reversing wheel 1111 is basically located on the cement rod 21. On the lower side, the end of the cement pole 21 located outside the bracket 14 is the loading end 211 and is fitted with a rope loop 31. Then, under the action of the second drive device 112, the telescopic beam 111 rotates upward and makes the telescopic beam 111 basically face the loading end 211 of one of the cement poles 21. Then the telescopic beam 111 extends and causes the reversing wheel 1111 to move to the side of the corresponding loading end 211 away from the first rotating plate 12. Then the steel cable 1113 is connected to the rope loop 31 of the corresponding loading end 211 through the reversing wheel 1111. The telescopic beam 111 is modeled after the boom of an existing crane. A mounting frame 15 is then installed on the base 11. The mounting frame 15 is located on the side of the loading end 211 furthest from the telescopic beam 111. Multiple displacement sensors 16 are installed on the mounting frame 15, arranged sequentially from top to bottom, corresponding one-to-one with the position of the loading end 211 of the cement pole 21. The displacement sensors 16 can be modeled after existing linear displacement sensors 16 with wireless transmission capabilities. During use, the linear displacement sensors 16 are placed against the loading end 211 furthest from the telescopic beam 111. The deflection of the loaded end 211 of the cement pole 21 after being subjected to force can be measured on one side of the telescopic beam 111. The displacement sensor 16 can transmit the measured deflection data of the loaded end 211 of the cement pole 21 to the back-end wirelessly in real time, so that the testing personnel can understand the test situation. During the test, the winch 1112 winds the steel cable 1113, and the steel cable 1113 pulls the cement pole 21 through the rope loop 31, and applies a force perpendicular to the axis of the cement pole 21, causing the cement pole 21 to bend. See Figure 15The direction of the force exerted by the steel cable 1113 on the cement rod 21 is parallel to that of the limiting plate 142, thereby reducing the influence of the limiting plate 142 on the deflection of the cement rod 21. Furthermore, a graphite layer can be provided on the upper side of the limiting plate 142 to reduce the friction between the cement rod 21 and the limiting block 145, thereby reducing the influence of friction on deflection and improving the accuracy of detection. When the steel cable 1113 loads the cement rod 21, the first support block 144 and the second support block 146 squeeze the cement rod 21. Under the action of the steel cable 1113, the first support block 144 and the second support block 146, the cement rod 21 bends, and the limiting block 145 separates from the cement rod 21, thereby preventing the limiting block 145 from affecting the deformation of the cement rod 21. When the cement rod 21 deflects at one end near the rotating roller 147, the rotating roller 147 rotates, reducing the influence of the rotating roller 147 on the deformation of the cement rod 21. A tension sensor is installed between the steel cable 1113 and the rope loop 31. The tension sensor is connected to the backend, which can obtain the tension force on the end of the cement pole 21 in real time. The greater the tension force, the greater the deflection of the loading end 211. The winch 1112 gradually increases the power, thereby gradually increasing the tension force on the loading end 211. When the force on the loading end 211 increases to a preset value, the deflection of the loading end 211 can be used to determine whether the tested cement pole 21 is qualified. Specifically, when the deflection is greater than the threshold, the cement pole 21 is unqualified, and vice versa. After testing one cement pole 21, the steel cable 1113 and the rope loop 31 are disconnected. Then, the second drive device 112 rotates the pole upwards or downwards by an angle, so that the telescopic beam 111 faces the loading end 211 of the other cement pole 21 to be tested. The telescopic beam 111 then extends or shortens, causing the reversing wheel 1111 to move to the side of the loading end 211 of the other cement pole 21 away from the first rotating plate 12, and the steel cable 1113 is connected to the rope loop 31 of the corresponding loading end 211. Then, the winch 1112 runs and loads the loading end 211. The same steps are used to test the cement pole 21. See [link to relevant documentation]. Figure 14 By following this process, all the cement poles 21 on the brackets 14 can be inspected. In this process, it is not necessary to repeatedly load and unload the cement poles 21 as in the traditional inspection method, which greatly improves the inspection efficiency.

[0044] In one implementation, a second rotating plate 17 is provided on the upper side of the first rotating plate 12. One side of the second rotating plate 17 is rotatably connected to the first rotating plate 12 and is provided with a second rotating axis 102 perpendicular to the first rotating axis 101. The second rotating axis 102 extends horizontally. The first rotating plate 12 is provided with a third driving device 121 for driving the second rotating plate 17 to rotate around the second rotating axis 102. The second rotating axis 102 is provided on the side of the bracket 14 near the rotating roller 147.

[0045] With the above setup, all the cement rods 21 on the bracket 14 can be quickly positioned. Specifically, initially, the second rotating plate 17 abuts against the upper side of the flip plate 122 and the positioning block 123, see [link to relevant documentation]. Figure 12 At this point, the second rotating plate 17 is horizontal. The bracket 14 and cement rod 21 are hoisted onto the second rotating plate 17, and the base plate 141 is fixed to the second rotating plate 17 with bolts. At this time, the end of the cement rod 21 away from the rotating roller 147 faces away from the flip plate 122. The second rotating axis 102 is perpendicular to the axis of the cement rod 21. Under the action of the third driving device 121, the end of the second rotating plate 17 away from the flip plate 122 rotates upwards by an angle. (See...) Figure 11 Under the influence of gravity, the cement rod 21 slides downward and abuts against the corresponding rotating roller 147, automatically positioning the cement rod 21. Then, under the action of the third drive device 121, the second rotating plate 17 rotates around the second rotating axis 102 and abuts against the positioning block 123 again, returning the second rotating plate 17 to a horizontal position. (See below) Figure 12 Then, under the action of the first driving device 13, the first rotating plate 12 rotates ninety degrees around the first rotation axis 101, and the first rotating plate 12 drives the second rotating plate 17 to rotate together. See [link / reference] Figure 13At this time, both the first rotating plate 12 and the second rotating plate 17 extend vertically, and the cement rods 21 are arranged sequentially from top to bottom. The axis of the cement rods 21 extends horizontally. Under the action of gravity, the cement rods 21 are pressed against the limiting plate 142, which is horizontal. One end of the cement rod 21 abuts against the rotating roller 147, thereby achieving the positioning of the cement rod 21. At this time, the axis of the rotating roller 147 extends vertically, and the other end of the cement rod 21 is suspended in the air. The cement rod 21 is located on the side of the first rotating plate 12 near the telescopic beam 111. The reversing wheel 1111 is located approximately below the concrete pole 21. The end of the concrete pole 21 outside the bracket 14 is the loading end 211 and is fitted with a rope loop 31. Then, under the action of the second drive device 112, the telescopic beam 111 rotates upward, causing the telescopic beam 111 to be approximately facing the loading end 211 of one of the concrete poles 21. The telescopic beam 111 then extends, causing the reversing wheel 1111 to move to the side of the corresponding loading end 211 away from the first rotating plate 12. Then, the steel cable 1113 is connected to the corresponding loading end 211 via the reversing wheel 1111. On the rope loop 31 of the loading end 211, the telescopic beam 111 is referenced to the boom of an existing crane. A mounting frame 15 is then installed on the base 11. The mounting frame 15 is located on the side of the loading end 211 away from the telescopic beam 111. Multiple displacement sensors 16 are installed on the mounting frame 15, arranged sequentially from top to bottom, corresponding one-to-one with the position of the loading end 211 of the cement pole 21. The displacement sensors 16 can refer to existing linear displacement sensors 16 with wireless transmission capabilities. During use, the linear displacement sensors 16 are placed against the loading end 211. The deflection of the loaded end 211 of the cement pole 21 after being subjected to force can be measured on the side of the telescopic beam 111 away from the loading end 211. The displacement sensor 16 can transmit the measured deflection data of the loaded end 211 of the cement pole 21 to the back-end wirelessly in real time, so that the testing personnel can understand the test situation. During the test, the winch 1112 winds the steel cable 1113, and the steel cable 1113 pulls the cement pole 21 through the rope loop 31, and applies a force perpendicular to the axis of the cement pole 21, causing the cement pole 21 to bend. See Figure 15The direction of the force exerted by the steel cable 1113 on the cement pole 21 is parallel to that of the limiting plate 142, thereby reducing the influence of the limiting plate 142 on the deflection of the cement pole 21. Furthermore, a graphite layer can be provided on the upper side of the limiting plate 142 to reduce the friction between the cement pole 21 and the limiting block 145, thereby reducing the influence of friction on deflection and improving the accuracy of detection. The clearance groove 143 is used to avoid the cement pole 21, thereby preventing the base plate 141 from affecting the deformation of the cement pole 21. When the steel cable 1113 loads the cement pole 21, the first support block 144 and the second support block 146 compress the cement pole 21. Under the action of 46, the cement rod 21 bends, the first groove 1441 fits into the cement rod 21, thereby reducing the pressure of the first support block 144 on the cement rod and preventing the first support block 144 from crushing the cement rod and affecting the detection of the cement rod. The second groove fits into the cement rod, thereby reducing the pressure of the second support block 146 on the cement rod and preventing the second support block 146 from crushing the cement rod and affecting the detection of the cement rod. The limiting block 145 disengages from the cement rod 21, thereby preventing the limiting block 145 from affecting the deformation of the cement rod 21. When the cement rod 21 deflects at one end near the rotating roller 147, the rotating roller 147 rotates, reducing the influence of the rotating roller 147 on the deformation of the cement rod 21. A tension sensor is installed between the steel cable 1113 and the rope loop 31. The tension sensor is connected to the backend, which can obtain the tension force on the end of the cement pole 21 in real time. The greater the tension force, the greater the deflection of the loading end 211. The winch 1112 gradually increases the power, thereby gradually increasing the tension force on the loading end 211. When the force on the loading end 211 increases to a preset value, the deflection of the loading end 211 can be used to determine whether the tested cement pole 21 is qualified. Specifically, when the deflection is greater than the threshold, the cement pole 21 is unqualified, and vice versa. After testing one cement pole 21, the steel cable 1113 and the rope loop 31 are disconnected. Then, the second drive device 112 rotates the pole upwards or downwards by an angle, so that the telescopic beam 111 faces the loading end 211 of the other cement pole 21 to be tested. The telescopic beam 111 then extends or shortens, causing the reversing wheel 1111 to move to the side of the loading end 211 of the other cement pole 21 away from the first rotating plate 12, and the steel cable 1113 is connected to the rope loop 31 of the corresponding loading end 211. Then, the winch 1112 runs and loads the loading end 211. The same steps are used to test the cement pole 21. See [link to relevant documentation]. Figure 14 By following this process, all the cement poles 21 on the brackets 14 can be inspected. In this process, it is not necessary to repeatedly load and unload the cement poles 21 as in the traditional inspection method, which greatly improves the inspection efficiency.

[0046] In one implementation, the base 11 includes an upper steel plate 113 and a lower steel plate 114 disposed on the lower side of the upper steel plate 113. The upper steel plate 113 and the lower steel plate 114 are fixedly connected by a connecting plate 115. The upper steel plate 113 is provided with a through hole 1131. The first driving device 13 includes a first hydraulic cylinder disposed between the first rotating plate 12 and the lower steel plate 114. One end of the first hydraulic cylinder is rotatably connected to the lower steel plate 114, and the other end of the first hydraulic cylinder is rotatably connected to the first rotating plate 12.

[0047] With the above configuration, the first rotating plate 12 can rotate around the first rotation axis 101. Specifically, when the first hydraulic cylinder extends, the first rotating plate 12 rotates upward. See [link to relevant documentation]. Figure 13 Conversely, when the first cylinder shortens, the second rotating plate 17 rotates downwards.

[0048] In one implementation, one side of the first rotating plate 12 extends upward to form a flap 122, the flap 122 is rotatably connected to the second rotating plate 17, a positioning block 123 is fixedly connected to the side of the first rotating plate 12 away from the flap 122, the positioning block 123 abuts against the second rotating plate 17, and the third driving device 121 includes a second hydraulic cylinder disposed between the first rotating plate 12 and the second rotating plate 17, one end of the second hydraulic cylinder is rotatably connected to the first rotating plate 12, and the other end of the second hydraulic cylinder is rotatably connected to the second rotating plate 17.

[0049] With the above configuration, the second rotating plate 17 can rotate around the second rotating axis 102. (See above) Figure 11 When the second cylinder extends, the second rotating plate 17 drives the bracket 14 to rotate upward; when the second cylinder retracts, the second rotating plate 17 drives the bracket 14 to rotate downward.

[0050] As one implementation method, the second drive device 112 is configured as a geared motor.
