[0002] When building a house, construction workers usually need to use climbing frames for high-altitude work, especially when building high-rise buildings, they need to pay close attention to the safety of the climbing frames. At present, the climbing frames have been transformed from traditional ones to new ones, namely attached lifting scaffolds. This equipment is a new type of scaffolding technology that has developed rapidly at the beginning of this century. It is more economical, safer and more convenient.

[0003] Currently, new types of climbing frames are widely used, but manual inspection and operation of the climbing frame lifting are still required during use; it is not intelligent enough and has low efficiency.

[0004] To this end, the present invention proposes an intelligent jacking control system for a climbing frame. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an intelligent jacking control system for a climbing frame, which solves the problem that the climbing frames currently used for high-altitude construction operations still require manual operation and are inefficient.

[0006] To achieve the above-mentioned purpose, an intelligent jacking control system for a climbing frame is proposed according to an embodiment of the present invention, comprising: a detection module, a data processing module, an alarm module, a lifting control module, a state detection module and an operation and maintenance management background;

[0007] The detection module is used to detect and obtain the parameters that affect the lifting process of the climbing frame, and send the detected data to the data processing module; the detection module includes a tension detection unit, a balance detection unit, a displacement detection unit, a lifting speed detection unit and a wind speed detection unit;

[0008] The data processing module is used to process the detection data sent by the detection module. When the climbing frame is currently moving, the climbing frame tension value, inclination, lifting displacement, lifting speed and wind speed of the climbing frame environment are compared with a preset threshold value, thereby giving corresponding control instructions to the lifting control module and sending corresponding prompt information to the alarm module.

[0009] The alarm module is used to voice broadcast the prompt information sent by the data processing module;

[0010] The lifting control module is used to control the operation of the corresponding climbing frame according to the control instructions sent by the data processing module;

[0011] The status detection module is used to detect whether the status of each module is normal. If any module is abnormal, the address and name of the abnormal module will be sent to the operation and maintenance management background;

[0012] The operation and maintenance management background notifies maintenance personnel to go to the corresponding location for maintenance according to abnormal conditions.

[0013] Furthermore, the tension detection unit is arranged on the lifting device, and is used to detect the tension of the lifting device lifting the climbing frame, that is, the current weight of the climbing frame; if the tension value is greater than or equal to the tension threshold, the data processing module sends a control instruction to stop lifting to the lifting control module, and a prompt information of the climbing frame being overweight to the alarm module; the lifting control module controls the lifting devices of all climbing frames to suspend operation, and at the same time controls the anti-fall device to brake and protect the climbing frame; the alarm module broadcasts the prompt information of the climbing frame being overweight through voice.

[0014] Furthermore, the balance detection unit is used to detect whether the entire climbing frame is in a horizontal balance state during the climbing frame lifting process or stabilization; if the inclination of the climbing frame is greater than or equal to the inclination threshold, the data processing module sends a control instruction to stop lifting to the lifting control module, and a prompt message that the climbing frame inclination exceeds the standard to the alarm module; the lifting control module immediately controls the lifting devices of all climbing frames to suspend operation, and at the same time controls the anti-tilt device to brake and protect the climbing frame; the alarm module broadcasts the prompt message that the climbing frame inclination exceeds the standard through voice.

[0015] Furthermore, the displacement detection unit is used to perform real-time detection of the lifting displacement of the climbing frame in the vertical direction, and the lifting speed detection unit is used to detect the lifting speed and speed direction of the climbing frame.

[0016] Furthermore, the data processing module marks the lifting displacement of the climbing frame as Xi, sorts the lifting displacements acquired in real time, calculates the maximum displacement difference XJ between the maximum lifting displacement Xmax and the minimum lifting displacement Xmin, and presets the threshold of the maximum displacement difference as XJS; wherein i represents the climbing frame number, i=1, 2, ...i;

[0017] If XJ≥XJS, the data processing module sends a control command to stop lifting to the lifting control module, and sends the climbing frame number of the maximum lifting displacement and the lifting distance of -(Xmax+Xmin) / 2, as well as the climbing frame number of the minimum lifting displacement and the lifting distance of (Xmax+Xmin) / 2 to the lifting control module; the data processing module also sends a prompt message that the lifting displacement difference exceeds the standard to the alarm module; the lifting control module controls the lifting devices of all climbing frames to suspend operation, and controls the lifting devices of the climbing frames with corresponding numbers to lower or raise the climbing frames according to the corresponding lifting distance; the alarm module broadcasts the prompt message that the lifting displacement difference exceeds the standard through voice;

[0018] If XJ<XJS, the data processing module calculates the average displacement Xa of all climbing frame lifting displacements, and subtracts the lifting displacement of all climbing frames from the average displacement value to obtain the absolute value of the displacement difference of the corresponding numbered climbing frame |Xi-Xa|. The maximum absolute value of the preset displacement difference is Xb.

[0019] Furthermore, if all climbing frames have |Xi-Xa|≤Xb, the data processing module does not perform corresponding processing. If |Xi-Xa|>Xb appears in the climbing frame, the data processing module performs analysis based on the lifting speed of the climbing frame.

[0020] If all the numbered climbing frames stop moving at this time, the data processing module sends the corresponding numbered climbing frame lifting displacement lifting ±|Xi-Xa| control instruction to the lifting control module, and the lifting control module controls the lifting device of the corresponding numbered climbing frame to rise or fall the distance |Xi-Xa|;

[0021] If all climbing frames are in the lifting state, the data processing module will sort the lifting speeds of all climbing frames in order, mark the lifting speed of the climbing frames as QVi, and preset the lifting speed threshold QVS; if QVi>QVS, the data processing module will send a control instruction to reduce the lifting speed of the climbing frame with the corresponding number to QVS to the lifting control module, and the lifting control module will control the lifting speed of the lifting device of the climbing frame with the corresponding number to be reduced to QVS; if QVi≤QVS, the data processing module will calculate the average lifting speed QVa of the climbing frames remaining after removing all the climbing frames with numbers |Xi-Xa|>Xb, and subtract QVa from the lifting speed QVi of all the climbing frames with numbers |Xi-Xa|>Xb to obtain the speed difference |QVi-QVa|. The data processing module will send the acquired speed difference of the climbing frame with the corresponding number to the lifting control module, and the lifting control module will increase or decrease the lifting speed of the lifting device of the climbing frame with the corresponding number according to the speed difference until the speed average QVa is met.

[0022] Furthermore, the wind speed detection unit is used to detect the wind speed in the natural environment where the climbing frame is located. If the wind speed is greater than or equal to the wind speed threshold, the data processing module sends a control instruction to stop lifting to the lifting control module, and a prompt message that the wind speed exceeds the standard is sent to the alarm module; the lifting control module controls the lifting device of all climbing frames to stop running, and the alarm module broadcasts the prompt message that the wind speed exceeds the standard through voice, reminding relevant staff to evacuate in an orderly manner.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, a climbing frame intelligent lifting control system includes: a detection module, a data processing module, an alarm module, a lifting control module, a state detection module and an operation and maintenance management background;

[0029] In the present application, the detection module is used to detect and obtain parameters that affect the lifting process of the climbing frame; wherein, the detection module is arranged in the climbing frame; the detection module includes a tension detection unit, a balance detection unit, a displacement detection unit, a lifting speed detection unit and a wind speed detection unit; in actual construction operations, different or equal numbers of climbing frames are arranged on different sides of the building, and all the climbing frames are spliced ​​together by connecting pieces; during the operation, all the climbing frames around the building need to be lifted and lowered synchronously; the climbing frame is mainly lifted and lowered by a lifting device, which is generally a wire rope electric hoist or a chain electric hoist;

[0030] The tension detection unit is arranged on the lifting device, and is used to detect the tension of the lifting climbing frame of the current lifting device, that is, the weight of the current climbing frame, and send the tension value obtained by the detection to the data processing module;

[0031] The balance detection unit is used to detect whether the entire climbing frame is in a horizontal balance state during the climbing frame lifting process or when it is stable, and send the climbing frame inclination obtained by the detection to the data processing module; in the real-time example of the present invention, the inclination of the climbing frame can be detected by a level measuring instrument or determined by measuring the angle between the weight line and the walkway board of the climbing frame. It can also be achieved by setting an infrared transmitter at every unit distance above or below the walkway board of the climbing frame. If the infrared light emitted by the infrared transmitter is refracted by the climbing frame material within the unit distance, the refractive index is calculated, and the deformation degree of the walkway board of the climbing frame and the inclination degree of the entire climbing frame are determined based on the refractive index;

[0032] The displacement detection unit is used to detect the lifting displacement of the climbing frame in the vertical direction in real time, and send the detected lifting displacement of the climbing frame to the data processing module; specifically, the displacement detection unit can be a displacement sensor, which is set at the midpoint of each climbing frame, and the displacement of the climbing frame when it starts to lift from the ground is recorded as 0, then when the climbing frame is rising or falling, the real-time height of the climbing frame is the lifting displacement of the climbing frame;

[0033] The lifting speed detection module is used to detect the lifting speed and speed direction of the climbing frame, and send the lifting speed obtained by detection to the data processing module; in the embodiment of the present invention, the lifting speed can be detected and obtained by the lifting speed detection device on the lifting device;

[0034] The wind speed detection unit is used to detect the wind speed in the natural environment where the climbing frame is located, and send the detected wind speed to the data processing module; specifically, a wind speed detector can be used for detection.

[0035] In this application, the data processing module is used to process the detection data sent by the detection module. The specific processing process is as follows:

[0036] Step S01: The data processing module marks the real-time acquired tension value as FLi, the climbing frame inclination as Di, the climbing frame lifting displacement as Xi, the climbing frame lifting speed as QVi, and the wind speed as FV; wherein i represents the climbing frame number, i=1, 2, ...i;

[0037] Step S02: the data processing module marks the tension threshold as FLS. If FLi≥FLS, the data processing module sends a control instruction to stop lifting to the lifting control module, and at the same time, the data processing module sends a prompt message that the climbing frame is overloaded to the alarm module;

[0038] The lifting control module immediately controls the lifting devices of all climbing frames to stop running, and at the same time controls the anti-falling device to brake and protect the climbing frames to prevent them from falling. The alarm module broadcasts the overweight prompt information of the climbing frames through voice, reminding the relevant staff to evacuate, or to move the materials on the climbing frames and evenly distribute them on the climbing frames.

[0039] The threshold of the climbing frame inclination is marked as DS. If Di≥DS, the data processing module sends a control command to stop lifting to the lifting control module, and a prompt message that the climbing frame inclination exceeds the standard is sent to the alarm module;

[0040] The lifting control module immediately controls the lifting devices of all climbing frames to stop running, and at the same time controls the anti-tilt device to brake and protect the climbing frame to prevent it from tipping over; the alarm module broadcasts the prompt information that the inclination of the climbing frame exceeds the standard through voice, and the relevant staff members stand still or slowly go to the adjacent normal climbing frame for evacuation;

[0041] Step S03: The data processing module sorts the lifting displacements acquired in real time, calculates the maximum displacement difference XJ between the maximum lifting displacement Xmax and the minimum lifting displacement Xmin, and presets the threshold of the maximum displacement difference as XJS;

[0042] If XJ ≥ XJS, the data processing module sends a control command to stop lifting to the lifting control module, and sends the climbing frame number of the maximum lifting displacement and the lifting distance of -(Xmax+Xmin) / 2, as well as the climbing frame number of the minimum lifting displacement and the lifting distance of (Xmax+Xmin) / 2 to the lifting control module; the data processing module also sends a prompt message that the lifting displacement difference exceeds the standard to the alarm module; it should be noted that a positive value of the lifting distance indicates an increase, and a negative value indicates a decrease;

[0043] The lifting control module immediately controls the lifting devices of all climbing frames to suspend operation, and controls the lifting devices of the climbing frames with corresponding numbers to lower or raise the climbing frames according to the corresponding lifting distances;

[0044] The alarm module broadcasts the information that the lifting displacement difference exceeds the standard through voice broadcast, notifying the relevant staff to stay still and wait for processing;

[0045] If XJ<XJS, the data processing module calculates the average displacement Xa of all climbing frame lifting displacements, and subtracts the lifting displacement of all climbing frames from the average displacement to obtain the absolute value of the displacement difference of the corresponding numbered climbing frame |Xi-Xa|, and the maximum absolute value of the preset displacement difference is Xb;

[0046] If all climbing frames |Xi-Xa|≤Xb, the data processing module will not perform corresponding processing;

[0047] If |Xi-Xa|>Xb appears in the climbing frame, the data processing module will analyze according to the climbing frame lifting speed;

[0048] If all the numbered climbing frames stop moving at this time, the data processing module sends the corresponding numbered climbing frame lifting displacement lifting ±|Xi-Xa| control instruction to the lifting control module, and the lifting control module controls the lifting device of the corresponding numbered climbing frame to rise or fall the distance |Xi-Xa|;

[0049] If all climbing frames are in the lifting state, the data processing module will sort the lifting speeds of all climbing frames in real time according to size, and preset the lifting speed threshold QVS; if QVi>QVS, the data processing module will send a control instruction to reduce the lifting speed of the climbing frame with the corresponding number to QVS to the lifting control module, and the lifting control module will control the lifting speed of the lifting device of the climbing frame with the corresponding number to be reduced to QVS; if QVi≤QVS, the data processing module will calculate the average lifting speed QVa of the climbing frames remaining after removing all the climbing frames with numbers |Xi-Xa|>Xb, and subtract QVa from the lifting speed QVi of all the climbing frames with numbers |Xi-Xa|>Xb to obtain the speed difference |QVi-QVa|, and the data processing module will send the acquired speed difference of the climbing frame with the corresponding number to the lifting control module, and the lifting control module will increase or decrease the lifting speed of the lifting device of the climbing frame with the corresponding number according to the speed difference until the speed average QVa is met;

[0050] Step S04: the data processing module marks the wind speed threshold as FVS. If FV is greater than or equal to FVS, the data processing module sends a control instruction to stop lifting to the lifting control module, and a prompt message that the wind speed exceeds the standard to the alarm module;

[0051] The lifting control module immediately stops the lifting devices of all climbing frames, and the alarm module broadcasts the wind speed exceeding the standard through voice, reminding relevant staff to evacuate in an orderly manner;

[0052] The status detection module is used to detect the operating status of the detection module, data processing module, alarm module and lifting control module. If any module is abnormal, the status detection module will send the detected abnormal module to the operation and maintenance management background, and the operation and maintenance management background will notify the maintenance personnel to go for maintenance.

The formula is a formula that is closest to the actual situation obtained by collecting a large amount of data and performing software simulation. The preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained by simulating a large amount of data.
