TECHNICAL FIELD
[0001] The utility model relates to tower crane jacking safety technical field especially relates to an intelligent safety detection system of tower crane jacking. BACKGROUND
[0002] Safety is the most important in engineering operation, if the safety measure does not reach the standard, then it is extremely easy to cause the serious safety accident such as tower crane collapse. Therefore only in the current safety condition meets the case can the next process begin.
[0003] In the current tower crane jacking process, the sleeve frame needs to be sleeved on the outside of the standard section, and the jacking assembly on the sleeve frame is used to realize the jacking of the sleeve frame itself, so as to install the new standard section on the original standard section. In the process, the sleeve frame adjusts the luffing trolley through the tower crane cab to realize the adjustment of the position of the standard section used for trimming, so as to adjust the positional relationship between the sleeve frame and the standard section. After adjustment, the on-site operator mainly relies on naked eye observation to observe the gap size between the total 16 guide wheels of the upper and lower layers of the sleeve frame and the main chord of the standard section, and confirms whether it is consistent (the gap size is usually between 2-4mm). Only after the hoisting arm of the tower crane is trimmed to ensure that the overall upper structure of the tower crane is in a horizontal state, the next jacking operation can be carried out.
[0004] However, the current method mainly relies on manual observation and monitoring, and the human eye can only roughly judge the distance between each guide wheel and the chord, which requires higher experience of the operator and has certain error in distance judgment. On the other hand, the monitoring effectiveness is not enough, and the control of the operation process is not strong enough. The single result of personnel judgment determines whether the jacking process can proceed, the judgment standards of each operator are different, and the operation state of the personnel is uncertain, which has certain safety risk.
[0005] There is also a method of using a proximity sensor for detection in the prior art, for example, a proximity switch is added at each standard section step, and the control loop is modified to allow jacking only when the proximity switch is closed. In this way, when the jacking cross beam and the safety pin are in place, it can be sensed to enable jacking. However, this method requires modification of all existing machines to add sensors, which is time-consuming and labor-intensive, and the cost is extremely high. UTILITY MODEL CONTENTS

Moreover, the monitoring camera can be detachably arranged on the sleeve frame, and the standard section does not need to be further added with a structure, so that the cost can be effectively reduced. The detachable arrangement between the monitoring camera and the sleeve frame enables the monitoring camera to be repeatedly used in various tower crane jacking systems, and the communication of the system does not need to be re-paired due to the replacement of the monitoring camera.

[0061] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0062] The present application will be described in further detail below with reference to the accompanying drawings.
[0063] The intelligent safety detection system for tower crane jacking is used in the tower crane commonly used in the existing building construction site, is used for detecting the safety of each part related to the jacking safety of the tower crane and the sleeve frame during the overall jacking process of the sleeve frame when the tower crane needs to jacking the sleeve frame to increase a new standard section on the existing standard section to increase the height of the tower crane. The intelligent safety detection system for tower crane jacking comprises a sleeve frame state detection system 81 and a detection and judgment system 85. The sleeve frame state detection system 81 is used for detecting the inclination angle of the sleeve frame 1, the inclination angle of the standard section 2 and the relative inclination angle between the sleeve frame 1 and the standard section 2. Only when the sleeve frame 1 and the standard section 2 are both horizontal or close to the horizontal state, the jacking can be safe. The detection and judgment system 85 is connected with the oil cylinder 12 of the sleeve frame 1, is used for obtaining the detection result of the sleeve frame state detection system 81, and judges whether the detection result meets the standard according to the preset standard requirement, so as to lock the oil cylinder 12 to not allow the tower crane to jacking when at least one detection result does not meet the standard, and unlock the oil cylinder 12 to allow the tower crane to jacking when all the detection results meet the standard.
[0064] Specifically, the detection of the inclination angle of the tower frame 1 by the tower frame state detection system 81 can be represented by the inclination angles of the main chords in at least two mutually perpendicular directions on the tower frame 1, and the detection of the inclination angle of the standard section 2 can also be represented by the inclination angles of the main chords in at least two mutually perpendicular directions on the standard section 2, and the relative inclination angle between the tower frame 1 and the standard section 2 can be represented by the relative inclination angles between the two groups of main chords in at least two perpendicular directions on the tower frame 1 and the standard section 2. The tower frame state detection system 81 includes a first monitoring camera group and an analysis processing module. The first monitoring camera group is composed of monitoring cameras, which are detachably installed on the tower frame 1 and can be lifted together with the tower frame 1. The first monitoring camera group is used to obtain detection picture data, which is used for analysis and processing to obtain the inclination angle data of the tower frame 1 and the standard section 2. The analysis processing module is used to analyze and process the obtained detection picture data, and then obtain the inclination angle data of the tower frame 1 and the standard section 2 to form the detection result of the tower frame state detection system 81. When analyzing and processing the detection picture data, the analysis processing module analyzes and processes the frame pictures in the obtained video data. The analysis processing module can be formed by a customized industrial computer. The industrial computer is a kind of reinforced enhanced personal computer, which has important computer properties and characteristics, such as computer, CPU, hard disk, memory, peripherals and interfaces, operating system, control network and protocol, computing power, and friendly human-computer interface. The industrial computer often runs in a relatively harsh environment, and the safety of data is also higher, so the industrial computer usually has special designs such as reinforcement, dustproof, moisture-proof, corrosion-proof, and radiation-proof. Each monitoring camera of the first monitoring camera group is in communication connection with the analysis processing module, so that the obtained detection picture data can be communicated and transmitted to the analysis processing module in real time to perform first analysis and processing on the detection picture data. The communication connection can be in the form of cable connection or wireless communication. The cable connection mode has faster signal acquisition, while the wireless communication mode does not require cables and thus does not need to consider the problem of cable length, which has certain advantages for signal transmission with the tower frame 1 located at high altitude.
[0065] As one possible implementation of the tower frame state detection system 81, the first monitoring camera group can include a first monitoring camera 31 and a second monitoring camera 32. The first monitoring camera 31 obtains first picture data including a first tower frame main chord 41 and a first standard section main chord 42 on the first side of the first side of the tower crane. The second monitoring camera 32 obtains second picture data including a second tower frame main chord 51 and a second standard section main chord 52 on the second side of the second side of the tower crane. Specifically, refer to Figures 1 to 3As shown, in this embodiment, located Figure 1 The central surveillance camera is the first surveillance camera 31. The first image data it acquires is from the first side of the tower crane, which is the side where the hydraulic cylinder 12 of the tower crane's frame 1 is located. The first image data acquired by the first surveillance camera 31 includes the main chord 41 of the first frame and the main chord 42 of the first standard section located on the first side of the tower crane. Figure 1 The main chord of the sleeve and the main chord of the standard section are located on the left side of the first side. Figure 2 The surveillance camera on the left is the second surveillance camera 32. The second image data it acquires is the image data from the second side of the tower crane. The second side and the first side are perpendicular to each other. Specifically, in this embodiment, the second side is... Figure 1 The left side of the tower crane. The second image data acquired by the second monitoring camera 32 includes the second main chord 51 of the second frame and the second standard section main chord 52 located on the second side of the tower crane, i.e. Figure 2 The main chord of the frame and the main chord of the standard section are located on the left side of the second side. That is, in this embodiment, the first camera group in the frame status detection system 81 acquires two sets of main chords of the frame and the standard section on two different sides of two mutually perpendicular sides of the tower crane.
[0066] Since the analysis processing module is in communication connection with the first monitoring camera group, the analysis processing module can obtain the detection picture data containing the first picture data and the second picture data obtained by the first monitoring camera group in real time. After obtaining the detection picture data obtained by the first monitoring camera group, the analysis processing module analyzes and processes the detection picture data. The analysis processing is processing the detection picture data to obtain the inclination angles of the sleeve 1 and the standard section 2 and the relative inclination angle between them. Specifically, the inclination angle of the first sleeve main chord 41 and the inclination angle of the first standard section main chord 42 can be determined according to the first picture data, then the inclination angle of the second sleeve main chord 51 and the inclination angle of the second standard section main chord 52 can be determined according to the second picture data, and finally the first relative inclination angle between the sleeve 1 and the standard section 2 can be determined according to the inclination angle of the first sleeve main chord 41 and the inclination angle of the first standard section main chord 42, and the second relative inclination angle between the sleeve 1 and the standard section 2 can be determined according to the inclination angle of the second sleeve main chord 51 and the inclination angle of the second standard section main chord 52. The processing of the first picture data and the second picture data is similar, and the order of the two can be interchanged, and after obtaining the inclination angle of the first sleeve main chord 41 and the inclination angle of the first standard section main chord 42 or the inclination angle of the second sleeve main chord 51 and the inclination angle of the second standard section main chord 52, the relative inclination angle between the main chords of the corresponding group can be directly determined. In the analysis and processing of the analysis processing module, the analysis and processing of the first picture data and the second picture data can be realized by processing the picture data according to the algorithm model in the prior art to obtain the inclination angles of the sleeve main chord and the standard section main chord. For example, taking the analysis and processing of the first picture data as an example, it can be realized by first extracting the center points of the first sleeve main chord 41 and the first standard section main chord 42 by using the gray center algorithm, then fitting the center lines of the first sleeve main chord 41 and the first standard section main chord 42 by using opencv, and finally determining the inclination angles of the first sleeve main chord 41 and the first standard section main chord 42 according to the fitted center lines. The analysis processing can also be realized by using other common methods in the prior art, such as directly calculating the inclination angles of the first sleeve main chord 41 and the first standard section main chord 42 by using the side lines, etc. In this embodiment, this will not be described in detail. Exemplarily, as shown in FIG. 16, the center points of the two objects are first extracted to obtain Figures 4 to 6 , then the center points of Figure 4 are fitted to form the center lines of the two objects to obtain Figure 5 , and finally the inclination angles of the two objects are determined according to the center lines. Figure 5 . In Figure 6 , the inclination angles of the two objects are determined according to the center lines. Figures 4 to 6In an embodiment of the first set of frame main chord 41, the calculated inclination angle is 88.11°, the inclination angle of the first standard section main chord 42 is 85.98°, and the first relative inclination angle between the first set of frame main chord 41 and the first standard section main chord 42 is 2.13°.
[0067] At the same time, in order to improve the accuracy of data detection and provide double protection for safety, the inclination sensor can also be arranged on the frame 1 and the standard section 2. The inclination sensor is in communication connection with the analysis processing module, and then the data detected by the inclination sensor is transmitted to the analysis processing module. After the first analysis processing is completed, the analysis processing module can compare the obtained result with the data detected by the inclination sensor to ensure the accuracy of the detection result.
[0068] In the above embodiment of the frame state detection system 81, the first monitoring camera 31 can be installed at the bottom of the lower working platform 11 of the frame 1, so that the detection picture data containing the frame main chord and the standard section main chord can be obtained before each jacking. Only two monitoring cameras are needed to complete the detection of the levelness of the frame 1 and the standard section 2, which can greatly reduce the number of monitoring cameras used, further reduce the cost of consumption, and reduce the amount of data processing, improve the analysis efficiency.
[0069] As another possible embodiment of the frame state detection system 81, this embodiment is similar to the embodiment shown in Figures 1 to 3 The first monitoring camera group of the frame state detection system 81 is provided with the first monitoring camera 31 and the second monitoring camera 32, and the picture positions monitored by the first monitoring camera 31 and the second monitoring camera 32 are the same as those in the embodiment shown in Figures 1 to 3 Specifically, referring to Figure 7 and Figure 8 The embodiment is similar to the embodiment shown in Figures 1 to 3The implementation method differs in that, in this implementation, among the main chords on the first side of the tower crane, a first marking strip 61 is provided on the first set of main chords 41, and a second marking strip 62 is provided on the first standard section main chord 42. Among the main chords on the second side of the tower crane, a third marking strip 63 is provided on the second set of main chords 51, and a fourth marking strip 64 is provided on the second standard section main chord 52. The marking strips can be set parallel to the corresponding main chords to directly indicate their direction, or they can be set at a certain angle to the corresponding main chords, allowing the direction of the main chords to be calculated from the preset angle difference. Preferably, the marking strips are elongated, and to make them more prominent in the image captured by the monitoring camera, a reflective coating can be provided on the surface of the marking strips.
[0070] In this embodiment, the analysis and processing performed by the analysis and processing module is related to... Figures 1 to 3 The analysis and processing performed by the analysis and processing module in the illustrated embodiment is similar. First, the tilt angles of the first marker bar 61, the second marker bar 62, the third marker bar 63, and the fourth marker bar 64 are determined. This allows the determination of the tilt angles of the first main chord 41, the first standard section main chord 42, the second main chord 51, and the second standard section main chord 52. Furthermore, the first relative tilt angle between the first main chord 41 and the first standard section main chord 42, and the second relative tilt angle between the second main chord 51 and the second standard section main chord 52 can be determined. The calculation of the tilt angles of the marker bars is similar to that of... Figures 1 to 3 In the embodiments shown, the calculation of the inclination angle of the main chord of the sleeve and the main chord of the standard section is similar, and this part will not be described in detail here.
[0071] In the above-described embodiment of the sleeve condition detection system 81, the analysis and processing of the marker strips replaces the analysis and processing of the main chord of the sleeve and the main chord of the standard section. Since the size of the marker strips is relatively small compared to the size of the main chord, the amount of computation during data processing can be reduced, while the accuracy of the analysis and processing can be improved, thus increasing the analysis efficiency.
[0072] In some possible implementations, the overall system may also include a lifting beam positioning detection system 82. This system 82 can also acquire corresponding detection image data via a monitoring camera, and then use an analysis and processing module to perform further analysis and processing on the detection image data to confirm whether the lifting beam 13 is in the correct position. (Refer to...) Figure 9It is shown that whether the position of the jacking cross beam 13 is in place is determined by the positional relationship between the shaft head 131 on the two sides of the jacking cross beam 13 and the step groove 21 on the standard section 2. Since the position of the jacking cross beam 13 is located at the lower part of the sleeve frame 1, the part of the detection picture data related to the jacking cross beam 13 can be obtained by the first monitoring camera group. Specifically, referring to Figure 1 It is shown that the first picture data obtained by the first monitoring camera 31 in the first monitoring camera group can contain the picture of the cooperation between the shaft head 131 on one side of the jacking cross beam 13 and the step groove 21 on the standard section 2. Further, referring to Figure 1 It is shown that the fifth monitoring camera 35, i.e. Figure 1 the monitoring camera on the right side in the middle, can also be provided. The fifth monitoring camera 35 is used to obtain the fifth picture data containing the cooperation between the shaft head 131 on the other side of the jacking cross beam 13 and the step groove 21 on the standard section 2, and the fifth monitoring camera 35 is also in communication connection with the analysis processing module. Further, the position of the jacking cross beam 13 can be detected by the first monitoring camera 31 and the fifth monitoring camera 35. After the first picture data detected by the first monitoring camera 31 and the fifth picture data detected by the fifth monitoring camera 35 are analyzed by the analysis processing module, the cooperation between the shaft head 131 of the jacking cross beam 13 and the step groove 21 on the standard section 2 can be obtained, such as whether the shaft head 131 of the jacking cross beam 13 is clamped into the step groove 21 on the standard section 2. The specific method of the analysis processing module for analyzing whether the shaft head 131 of the jacking cross beam 13 is clamped into the step groove 21 on the standard section 2 according to the first picture data and the fifth picture data can be to extract the local image of the target object (the shaft head 131 of the jacking cross beam 13 and the step groove 21) by an algorithm model, and match it with the picture of the shaft head 131 clamped into the step groove 21 by the algorithm model, so as to obtain whether the shaft head 131 of the jacking cross beam 13 is clamped into the step groove 21 on the standard section 2. The algorithm model for extracting the target object can use the YOLO model and other algorithm models commonly used in the prior art, and the algorithm model for matching and identifying can use the template matching model, which will not be listed here.
[0073] In addition, in the jacking beam in place detection system 82, a surface stress sensor and a proximity switch can also be added for detection. Specifically, the surface stress sensor can be arranged on the shaft head 131 of the jacking beam 13 to detect the surface stress on the shaft head 131, so as to determine whether the shaft head 131 of the jacking beam 13 is clamped into the step groove 21 on the standard section 2. The proximity switch can also be arranged on the shaft head 131 of the jacking beam 13 to detect whether the shaft head 131 of the jacking beam 13 is in contact with other structures, so as to determine whether the shaft head 131 of the jacking beam 13 has been clamped into the step groove 21 of the standard section 2 according to the detection result. In addition, the jacking beam in place detection system 82 can further detect whether the safety pin between the jacking beam 13 and the support block step 22 has been inserted, so as to further improve the safety of the jacking process.
[0074] In some possible embodiments, a rotary lower support bolt connection detection system 83 can also be included in the overall system. The rotary lower support bolt detection system 83 can include a bolt monitoring camera group for obtaining third detection picture data including a picture of the bolt connection position between the rotary lower support 14 and the sleeve frame 1. The bolt monitoring camera group can be provided with only one monitoring camera, or can be provided with a plurality of monitoring cameras. Since the connection position between the rotary lower support 14 and the sleeve frame 1 is located at the top of the sleeve frame 1, the bolt monitoring camera group can be arranged on the upper part of the sleeve frame 1 to monitor upwardly, or arranged at the balance arm or the boom guard of the tower crane, so as to detect the bolt connection condition between the rotary lower support 14 and the sleeve frame 1 (the arrangement of the bolt monitoring camera group is not shown in the drawings). The bolt between the rotary lower support 14 and the sleeve frame 1 is provided with an intelligent early warning nut, which can emit a red light when the pre-tightening force is insufficient, so that the bolt monitoring camera group can determine the bolt connection condition by detecting the number of pre-tightening intelligent warning nuts. The bolt monitoring camera group is also in communication connection with the analysis and processing module, so that the analysis and processing module can obtain the third detection picture data obtained by the bolt monitoring camera group in real time. The analysis and processing module also analyzes the third detection picture data to obtain the number of intelligent early warning nuts and the number of pre-tightening intelligent early warning nuts as the detection result, so as to determine whether the adjacent standard sections 2 are connected stably, and to avoid safety problems during the jacking of the sleeve frame 1.
[0075] In some possible embodiments, a climbing shoe to position detection system 84 can also be included in the overall system. The climbing shoe to position detection system 84 can include a climbing shoe monitoring camera group for acquiring fourth detection picture data including each climbing shoe 15 on the sleeve frame 1 and the support block step 22 on the standard section 2. The climbing shoe monitoring camera group can be provided with only one monitoring camera or multiple monitoring cameras, which can be arranged below the upper working platform on the upper part of the sleeve frame 1 to monitor the cooperation between the support block step 22 on the standard section 2 located on the upper part of the sleeve frame 1 and the climbing shoe 15 located on the upper part of the sleeve frame 1 (the arrangement of the climbing shoe monitoring camera group is not shown in the drawings). Figure 3 and Figure 10 As shown in Figs. 15 and 16, since the cooperation between the climbing shoe 15 and the support block step 22 needs to be confirmed before the oil cylinder 12 is retracted, the detection of the climbing shoe to position detection system 84 is mainly before the retraction of the oil cylinder 12 in the jacking process. The climbing shoe monitoring camera group is also in communication connection with the analysis processing module, so that the analysis processing module can acquire the fourth detection picture data acquired by the climbing shoe monitoring camera group in real time. The analysis processing module also analyzes the fourth detection picture data to obtain the relative position condition between each climbing shoe 15 on the sleeve frame 1 and the support block step 22 as a detection result, such as whether the climbing shoe 15 is in abutting cooperation with the support block step 22.
[0076] The detection judgment system 85 is connected with the oil cylinder 12 of the sleeve frame 1 to control the locking or unlocking of the oil cylinder 12. The detection judgment system 85 can be composed of the analysis processing module or formed by another separately provided industrial computer. Figure 11 The principle block diagram of the intelligent safety detection system of the tower crane jacking in an embodiment of the present application is schematically shown, and specifically, in this embodiment, the overall system is additionally arranged with the jacking cross beam to position detection system 82, the rotating lower support bolt connection detection system 83 and the climbing shoe to position detection system 84, and the detection judgment system 85 needs to acquire the detection results of the sleeve frame state detection system 81, the jacking cross beam to position detection system 82, the rotating lower support bolt connection detection system 83 and the climbing shoe to position detection system 84. In the embodiment of the detection judgment system 85 composed of the analysis processing module, since the detection results of the above-mentioned systems are all located in the analysis processing module, the detection results of the above-mentioned systems can be directly acquired. In the embodiment of the detection judgment system 85 formed by another separately provided industrial computer, the detection judgment system 85 needs to be in communication connection with the analysis processing module to acquire the detection results of the above-mentioned systems obtained by the analysis processing module. After the detection results of the systems are acquired, whether each part meets the standard is judged according to the corresponding detection results, and the oil cylinder 12 is unlocked to confirm that the tower crane jacking is allowed only when the detection results of the systems all meet the standard.
[0077] Specifically, when judging whether the detection result of the sleeve state detection system 81 meets the standard, the inclination angle of the sleeve 1, the inclination angle of the standard section 2, and the relative inclination angle of the two in the sleeve state detection system 81 can be compared with the preset fault-tolerant inclination angle. If the relative inclination angle is less than the fault-tolerant inclination angle, it is considered to meet the standard. The specific fault-tolerant inclination angle can include a relative inclination angle fault-tolerant value and a main chord inclination angle fault-tolerant value. The size of the relative inclination angle fault-tolerant value can be specifically set to ±1.5°, and the size of the main chord inclination angle fault-tolerant value can be specifically set to 90±3°. When calculating the inclination angles of the sleeve main chord and the standard section main chord of multiple groups, and the relative inclination angles of the sleeve 1 and the standard section 2 of multiple groups, the inclination angle of each group of sleeve main chord and standard section main chord should be compared with the main chord inclination angle fault-tolerant value, and the relative inclination angle of each group of sleeve 1 and standard section 2 should be compared with the relative inclination angle fault-tolerant value. Only when each group of inclination angle data meets the requirements, it is considered to meet the standard.
[0078] When judging whether the detection result of the jacking cross beam in-place detection system 82 meets the standard, it can be confirmed whether the shaft heads 131 at both ends of the jacking cross beam 13 have been clamped into the step grooves 21 of the standard section 2. If the shaft heads 131 at both ends of the jacking cross beam 13 have been clamped into the step grooves 21 of the standard section 2, it is considered to meet the standard. In addition, it is also detected whether the safety pin between the jacking cross beam 13 and the support block step 22 has been inserted into the climbing claw in-place detection system 84. The detection result meeting the standard also includes that the safety pin between the jacking cross beam 13 and the support block step 22 has been inserted.
[0079] When judging whether the detection result of the rotating lower support bolt connection detection system 83 meets the standard, it can be confirmed whether the number of detected intelligent early warning nuts is sufficient and whether the intelligent early warning nuts are in a pre-tightening state. If the number of detected intelligent early warning nuts is sufficient and the intelligent early warning nuts are in a pre-tightening state, it is considered to meet the standard.
[0080] When judging whether the detection result of the climbing claw in-place detection system 84 meets the standard, it can be confirmed whether each climbing claw 15 on the sleeve 1 is in abutting cooperation with the support block step 22. If each climbing claw 15 on the sleeve 1 is in abutting cooperation with the support block step 22, it is considered to meet the standard. Among them, for the detection result of the climbing claw in-place detection system 84, the detection result of the climbing claw in-place detection system 84 can be ignored before the extension of the oil cylinder 12 in the jacking process, and the detection result of the climbing claw in-place detection system 84 needs to meet the standard in the detection judgment before the retraction of the oil cylinder 12.
[0081] When the detection results of the sleeve frame state detection system 81, the jacking cross beam in place detection system 82, the rotary lower support bolt connection detection system 83 and the climbing claw in place detection system 84 all meet the standard, the detection judgment system 85 will unlock the oil cylinder 12 at this time, so that the tower crane can be jacked up. The detection judgment system 85 is connected with the oil cylinder 12 of the sleeve frame 1, so as to lock or unlock the oil cylinder 12 through electric control, and when there is a detection result that does not meet the standard, the tower crane driver cannot start the oil cylinder 12 to jack up the sleeve frame 1, only when all the detection results meet the standard, the oil cylinder 12 is unlocked, and the tower crane driver can start the oil cylinder 12 to jack up the sleeve frame 1, which provides safety guarantee for the whole jacking process.
[0082] In the above detection systems, the monitoring camera can be set as an intelligent cloud platform camera, which can be connected with the analysis processing module to control and adjust the shooting range of the monitoring camera, so as to reduce the number of monitoring cameras. The pixel requirement of the monitoring camera is not less than 4 million pixels, so as to ensure the accuracy of the detection result obtained from the obtained detection picture data.
[0083] In addition, a portable mounting bracket can be arranged between the monitoring camera and the sleeve frame 1 to realize detachable connection between the monitoring camera and the sleeve frame 1. Specifically, the portable mounting bracket can include a connecting rod 71 detachably connected with the monitoring camera, a rod sleeve 72 slidably sleeved on the connecting rod 71, and a first clamping structure for fixing the rod sleeve 72 on the sleeve frame 1. The rod sleeve 72 is further provided with a second clamping structure for fixing the position of the rod sleeve 72 and the connecting rod 71. In this way, the rod sleeve 72 of the portable mounting bracket can be detachably fixed on the sleeve frame 1 through the first clamping structure, and the monitoring camera can be detachably mounted on the connecting rod 71, and the connecting rod 71 and the rod sleeve 72 are slidably connected and fixed through the second clamping structure, so that the monitoring camera can adjust its position along the length direction of the connecting rod 71 to adjust the detection picture data obtained by the monitoring camera. For example, as shown in Figure 12 Figure 12 In the shown embodiment, the connecting rod 71 of the portable mounting support is a round rod, one end of the connecting rod 71 is connected with the monitoring camera through a bolt, the rod sleeve 72 is sleeved on the connecting rod 71, the second clamping structure is provided as a first screw 73 penetrating through the rod sleeve 72, and the relative fixation between the rod sleeve 72 and the connecting rod 71 is realized by screwing the first screw 73 to abut against the connecting rod 71. The first clamping structure provided on the rod sleeve 72 comprises first and second clamping plates arranged in parallel, and the first screw 74 is provided on the first clamping plate in a penetrating manner. During installation, the first and second clamping plates are arranged on both sides of the frame of the sleeve frame 1, and the second screw 74 is screwed to abut against the frame of the sleeve frame 1, so that the monitoring camera is detachably mounted on the sleeve frame 1.
[0084] The intelligent safety detection system for tower crane jacking of the utility model can comprehensively detect the links and parts between the sleeve frame 1 and the standard section 2 that will affect the jacking safety during the jacking process of the tower crane through multiple systems in all directions, including the position of the jacking cross beam 13, the bolt connection between the sleeve frame 1 and the rotary lower support 14, the cooperation between the climbing claw 15 and the support block step 22, and the levelness of the overall sleeve frame 1 and the standard section 2. At the same time, when detecting the levelness of the overall sleeve frame 1, the leveling relationship between the sleeve frame 1 and the standard section 2 is detected by the monitoring camera (the first monitoring camera group) detachably mounted on the sleeve frame 1 in combination with the inclination angle calculation algorithm, so as to replace the manual naked-eye observation mode for judgment, and since the monitoring camera can be detachably mounted on the sleeve frame 1, it is not necessary to further add structures to the standard section 2, so that the cost can be effectively reduced, and the detachable installation between the monitoring camera and the sleeve frame 1 can enable the monitoring camera to be repeatedly used in various tower crane jacking systems, without the need to re-pair the communication of the system due to replacement of the monitoring camera, and the monitoring camera can be detached after completing the jacking, so as to avoid damage to the monitoring camera when the sleeve frame 1 is stored.
