Description

Technical Field

[0001] The invention relates to the technical field of lifting equipment, in particular to an intelligent remote automatic operating system for building lifting equipment. Background Art

[0002] Construction lifting equipment, such as tower cranes, generally includes equipment base, lifting mechanism for grabbing building materials, lifting and rotating drive mechanism and rotating drive mechanism for driving the lifting mechanism to lift and rotate, and slewing vane brake for releasing the lifting mechanism and switching the braking state when the lifting equipment is closed. Among them, the slewing vane brake is a brake used for manual or electric release when the lifting equipment is not working for a long time or encounters typhoon weather. It can switch the slewing motor to the released state, so that the lifting mechanism, such as the tower crane boom, is in a state of free rotation with the wind. The released lifting mechanism can rotate freely with the wind and adjust to the downwind state, so that the windward area of ​​the lifting mechanism is minimized and the windward resistance is minimized, avoiding damage to the lifting equipment due to excessive wind force.

[0003] There are two main ways to use the existing slewing wind vane brake: one is to manually control the brake through the manual release button installed on the slewing wind vane brake; the other is to electrically control the slewing wind vane brake to open by operating the wind vane button on the linkage platform in the tower crane driver's room.

[0004] Existing wind vane brake control methods all require operators to operate on the lifting equipment. If the lifting equipment staff finds that the wind vane control operation has not been performed after leaving the equipment, the on-site personnel are required to climb back onto the lifting equipment to operate, which is cumbersome and troublesome to use. During manual operation, the lifting mechanism only rotates by itself under the action of wind. When the wind conditions are bad, there are problems such as the lifting mechanism rotating too fast or the equipment malfunctioning, making it impossible to perform effective operations, resulting in damage to the lifting equipment or even a dangerous situation of tipping over. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent remote automatic operation system for construction lifting equipment in order to solve the problem that the weather vane brake on the lifting equipment is inconvenient to operate and the structure cannot respond effectively and stably, resulting in damage to the lifting equipment or even dangerous situations such as tipping over.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: an intelligent remote automatic operation system for construction lifting equipment, comprising a data acquisition system and a remote control system, wherein the data acquisition system comprises an equipment appearance acquisition module, an equipment orientation acquisition module, an equipment speed acquisition module and a wind condition acquisition module, and the remote control system comprises a parameter entry module, a steering simulation module, a weather vane control module, a reducer control module, a status display module and a height control module;

[0007] The equipment orientation acquisition module is configured to acquire the orientation of the lifting mechanism in the construction lifting equipment;

[0008] The wind condition collection module is configured to collect the ambient wind speed and wind direction of the airflow around the lifting mechanism;

[0009] The steering simulation module simulates the process of the lifting mechanism naturally rotating to be parallel to the ambient wind direction when the wind vane brake is released based on the acquired direction of the lifting mechanism and the surrounding wind conditions, and records the rotation speed data and makes a result judgment;

[0010] The weather vane control module is used for remote control of the weather vane brake switch on the building lifting equipment.

[0011] As a further description of the above technical solution:

[0012] The equipment appearance acquisition module scans the appearance of the lifting mechanism and transmits the acquired appearance parameters to the steering simulation module, and the steering simulation module performs 3D modeling and force analysis on the lifting mechanism.

[0013] As a further description of the above technical solution:

[0014] The parameter input module is used to set the speed threshold of the lifting mechanism, and the speed threshold is used for result judgment of the steering simulation module. When the maximum value of the lifting mechanism speed data simulated by the steering simulation module is less than the speed threshold, the wind vane brake is switched to a released state through the wind vane control module.

[0015] As a further description of the above technical solution:

[0016] The reducer control module is remotely associated with the reducer on the lifting mechanism. The reducer control module is used for speed regulation and control when the lifting mechanism rotates. It is used for the lifting mechanism force rotation simulation and result judgment of the steering simulation module.

[0017] As a further description of the above technical solution:

[0018] The equipment speed acquisition module is configured to acquire the rotation rate of the lifting mechanism in real time, and the equipment speed acquisition module is associated with the reducer control module.

[0019] As a further description of the above technical solution:

[0020] The status display module is used to display the data information acquired by the equipment direction acquisition module, the wind condition acquisition module, and the equipment rotation speed acquisition module.

[0021] As a further description of the above technical solution:

[0022] Within the default response time after the wind vane control module controls the wind vane brake to switch to the released state, if the lifting mechanism rotation rate obtained by the equipment speed acquisition module is within the default stop speed range, the wind vane fault information is displayed through the status display module.

[0023] As a further description of the above technical solution:

[0024] The height control module is remotely associated with a lifting mechanism on the lifting mechanism for height adjustment.

[0025] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

The present invention acquires the orientation information of the lifting mechanism through the equipment orientation acquisition module, and the wind condition acquisition module acquires the wind condition information around the lifting mechanism, and uniformly transmits it to the steering simulation module, adds the acquired three-dimensional wind condition information to the pre-recorded lifting equipment model, simulates the process of the lifting mechanism rotating from the acquired initial orientation to the direction parallel to the airflow direction, and records the rotation speed during the process, compares the rotation speed change diagram with the input rotation speed threshold, and makes a result judgment, when the wind condition will not cause the lifting mechanism to rotate and the lifting equipment to become unstable or collapse, and at the same time, judges whether the lifting equipment needs to rotate according to the force analysis results of the steering simulation module. If necessary, the wind vane control module remotely controls the wind vane brake to release it, so as to realize the remote control of the natural rotation of the lifting mechanism to the minimum windward state, the most stable state, and the low-loss use of the lifting equipment.

[0036] Embodiment 1:

[0037] See also Figure 1 The present invention provides a technical solution: an intelligent remote automatic operating system for construction hoisting equipment, comprising a data acquisition system and a remote control system, wherein the data acquisition system comprises an equipment appearance acquisition module, an equipment orientation acquisition module, an equipment speed acquisition module and a wind condition acquisition module, and the remote control system comprises a parameter entry module, a steering simulation module, a weather vane control module, a reducer control module, a status display module and a height control module;

[0038] The equipment orientation acquisition module is configured to acquire the orientation of the lifting mechanism in the construction lifting equipment;

[0039] The wind condition collection module is configured to collect the ambient wind speed and wind direction of the airflow around the lifting mechanism;

[0040] The steering simulation module simulates the process of the lifting mechanism naturally rotating to be parallel to the ambient wind direction when the wind vane brake is released based on the acquired direction of the lifting mechanism and the surrounding wind conditions, and records the rotation speed data and makes a result judgment;

[0041] The weather vane control module is used for remote control of the weather vane brake switch on the building lifting equipment.

[0042] The parameter input module is used to set the speed threshold of the lifting mechanism, and the speed threshold is used for result judgment of the steering simulation module. When the maximum value of the lifting mechanism speed data simulated by the steering simulation module is less than the speed threshold, the wind vane brake is switched to a released state through the wind vane control module.

[0043] The status display module is used to display the data information obtained by each module of the data acquisition system and the remote control system. This design makes the display of equipment operating parameters on the remote operating device when operating the construction lifting equipment more complete, thereby improving the efficiency and transparency of remote control and equipment response operation.

[0044] The working principle of an intelligent remote automatic operation system for construction lifting equipment of this embodiment includes: the construction lifting equipment corresponding to this intelligent remote automatic operation system includes an equipment base, a lifting mechanism for grabbing building materials, a lifting drive mechanism and a rotating drive mechanism for driving the lifting mechanism to lift and rotate, and a weather vane brake for releasing the lifting mechanism and switching the braking state when the lifting equipment is closed. When the wind conditions in the environment where the construction lifting equipment is located are bad, the weather vane brake on the construction lifting equipment can be controlled by a remote control device, such as a mobile phone, a computer, etc., so that the lifting mechanism on the lifting equipment is naturally rotated to be parallel to the ambient airflow under the action of the ambient wind force, so as to reduce the windward area of ​​the lifting equipment, reduce the overall force, and improve stability. When in use, the orientation information of the lifting mechanism is acquired through the equipment orientation acquisition module, and the wind condition acquisition module acquires the wind condition information around the lifting mechanism and transmits it to the steering simulation module in a unified manner. The acquired three-dimensional wind condition information is added to the pre-recorded lifting equipment model to simulate the process of the lifting mechanism rotating from the acquired initial orientation to a direction parallel to the airflow direction, and the rotation speed during the period is recorded. The rotation speed change diagram is compared with the input rotation speed threshold, and the result is judged. When the wind condition will not cause the lifting mechanism to rotate and the lifting equipment to become unstable or collapse, at the same time, according to the force analysis results of the steering simulation module, it is judged whether the lifting equipment needs to rotate. If necessary, the wind vane control module remotely controls the wind vane brake to release it, so as to realize remote control of the natural rotation of the lifting mechanism to the minimum windward state and the most stable state.

[0045] Embodiment 2:

[0046] See also Figure 1 On the basis of the above-mentioned embodiment 1, preferably, the equipment appearance acquisition module scans the appearance of the lifting mechanism and transmits the acquired appearance parameters to the steering simulation module, and the steering simulation module performs 3D modeling and force analysis on the lifting mechanism.

[0047] The working principle of an intelligent remote automatic operation system for construction lifting equipment in this embodiment includes: the appearance data of the lifting equipment is acquired in real time by the equipment appearance acquisition module, so that the 3D model referenced by the steering simulation module is more in line with the actual situation, thereby improving the matching degree between the simulation results and the actual results.

[0048] Embodiment three:

[0049] See also Figure 1 On the basis of the above-mentioned embodiment 1, preferably, the reducer control module is remotely associated with the reducer on the lifting mechanism, and the reducer control module is used for speed regulation control when the lifting mechanism rotates, and is used for the lifting mechanism force rotation simulation and result judgment of the steering simulation module.

[0050] The equipment speed acquisition module is configured to acquire the rotation rate of the lifting mechanism in real time, and the equipment speed acquisition module is associated with the reducer control module.

[0051] The working principle of an intelligent remote automatic operating system for construction lifting equipment of this embodiment includes: when the external wind speed of the lifting equipment is too high, the lifting mechanism rotates by natural wind force, which can easily cause the overall instability of the equipment. At this time, the rotation intervention of the lifting mechanism can be carried out through the reducer control module, so that it can rotate at a relatively low speed under high wind speed conditions, thereby improving the feasibility and scope of application of the remote control of the wind vane brake of the lifting equipment. The remote control module can also play a role in the use environment where the wind conditions change frequently. When the wind vane brake is switched to the release state and the lifting mechanism rotates, if the equipment speed acquisition module detects that the actual speed of the lifting mechanism is too fast and exceeds the set speed threshold, the reducer control module remotely controls the reducer to reduce the degree of deceleration of the lifting mechanism rotation so that it is adjusted to a controllable range.

[0052] Embodiment 4:

[0053] See also Figure 1 On the basis of the above-mentioned embodiment 1, preferably, within the default response time after the wind vane control module controls the wind vane brake to switch to the release state, if the rotation rate of the lifting mechanism acquired by the equipment speed acquisition module is within the default stop speed range, the wind vane fault information is displayed through the status display module. Among them, the default response time is the time value set by default in this system, and the default stop speed range is the natural swing and rotation rate range of the lifting mechanism measured by experimental simulation under the condition that the lifting equipment is not running, the wind vane brake is in the braking state, and its stability can be guaranteed. Of course, the above default values ​​can be modified through the parameter entry module based on the use of the equipment.

[0054] The height control module is remotely connected to the lifting mechanism on the hoisting mechanism for height adjustment. When the simulation result of the steering simulation module shows that the stability of the equipment cannot be achieved when the hoisting mechanism rotates, or the wind vane brake or equipment fails and the hoisting mechanism cannot rotate, the state display module displays the fault information in time and alarms, and the height control module is used to adjust the height of the hoisting mechanism to change the wind conditions in the environment, dock at a reasonable height, and ensure the stability of the equipment under the wind conditions.

[0055] In summary, due to the adoption of the above technical solution, the intelligent remote automatic operation system for construction hoisting equipment of this embodiment has the following beneficial effects compared with the prior art:

[0056] 1. The present invention acquires the orientation information of the lifting mechanism through the equipment orientation acquisition module, and the wind condition acquisition module acquires the wind condition information around the lifting mechanism, and uniformly transmits it to the steering simulation module, adds the acquired three-dimensional wind condition information to the pre-recorded lifting equipment model, simulates the process of the lifting mechanism rotating from the acquired initial orientation to the direction parallel to the airflow direction, and records the rotation speed during the process, compares the rotation speed change diagram with the input rotation speed threshold, and makes a result judgment, when the wind condition will not cause the lifting mechanism to rotate and the lifting equipment to become unstable or collapse, and at the same time, judges whether the lifting equipment needs to rotate according to the force analysis results of the steering simulation module. If necessary, the wind vane control module remotely controls the wind vane brake to release it, so as to realize the remote control of the natural rotation of the lifting mechanism to the minimum windward state, the most stable state, and the low-loss use of the lifting equipment.

The height adjustment of the lifting mechanism can be achieved through the height control module to ensure stable parking of the equipment.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
