Description

Technical Field

[0001] The invention relates to the technical field of tower cranes, and in particular to a tower crane system and an attached operating platform device thereof. Background Art

[0002] Tower crane is also known as tower crane. It refers to a rotating crane with a boom mounted on the upper part of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in housing construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom and base, etc. The working mechanism has four parts: lifting, luffing, rotation and walking. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc. On construction sites, we often see that operators must first climb to a height of tens or even hundreds of meters to carry out hoisting operations in order to accurately deliver building materials to the designated construction site. The attachment platform is an operating platform set up below the installation position for tower crane operators to better operate safely during attachment installation. The traditional platform construction requires the steel pipe to be extended into the inner side of the standard section and placed on the beam, and then the outer ring steel pipe of the standard section is set up, and fasteners are used to effectively connect the inner and outer steel pipes to tighten the tower crane standard section. The disadvantages of using traditional attachment platforms are: it is difficult for workers to stand during the installation and disassembly of traditional attachment platforms, the space is small, the construction is inconvenient, and the installation and disassembly of ordinary steel pipes is complicated, there are many connection nodes, and the risk is relatively high. During the construction process, it is easy to cause the risk of people falling from heights; ordinary steel pipe materials are scattered and numerous, and cannot be stacked neatly, which can easily cause materials to fall from high altitudes during the installation and disassembly process; steel pipe materials have a small span, heavy weight, and many parts that are easily damaged, resulting in the material wall thickness not meeting the requirements and weak bearing capacity.

[0003] Chinese patent publication number CN113307162A discloses an attachment device for tower cranes attached to a wall and its installation process, wherein the attachment device is composed of two sets of frame beams and four attachment struts; the two sets of frame beams are fastened into an attachment frame by 24 sets of M27 bolts, nuts, and washers, and four attachment struts are hinged to the four vertices of the attachment frame, and the ends of the four attachment struts are provided with connecting sleeves, and the connecting sleeves are hinged to the connecting base at the attachment point of the building, and the four struts should be kept in the same horizontal plane, and the inner struts can be pushed to press against the four main chords of the tower body by adjusting the bolts. The invention has a simple structure, is easy to assemble and install, improves the adjustable pull rod attachment frame structure of the tower crane, and greatly saves labor costs and time costs.

[0004] It can be seen that the above invention has the following problem: it only considers the installation efficiency of the tower crane attachment device, but does not consider the influence of the attachment device on the stability of the tower crane. Summary of the invention

[0061] Specifically, the actual implementers can adjust the number of balancing components according to the actual situation. Preferably, there are four balancing components, which are symmetrically arranged at the four connecting corners of the attachment operation platform device.

[0062] A parameter monitoring module, used to obtain environmental parameters of several preset positions during the operation of the tower crane and force parameters of the attached operating platform device; the environmental parameters include wind speed and wind direction; the force parameters include force magnitude and force direction;

[0063] It should be noted that those skilled in the art know that any device capable of detecting wind speed and wind direction in the prior art falls within the protection scope of the present invention and will not be described in detail herein.

[0064] In implementation, the preset position at least includes the top of the tower body and the tower body position corresponding to the attached operation platform device.

[0065] Specifically, the parameter monitoring module includes:

[0066] An environmental parameter monitoring submodule, which is used to obtain environmental parameters of the top position of the tower body and the tower body position corresponding to the attached operation platform device during the operation of the tower crane;

[0067] The force parameter monitoring submodule is used to obtain the force parameters of the attached operating platform device at several preset force positions during the operation of the tower crane.

[0068] In implementation, the preset force-bearing position at least includes the connection position between the balancing component and the attachment operating platform device.

[0069] The parameter monitoring module of the present invention can improve the accuracy of subsequent judgment by setting an environmental parameter monitoring submodule and a force parameter monitoring submodule to respectively monitor the environmental parameters of the tower top position and the tower position corresponding to the attached operation platform device and the force parameters of the attached operation platform device at several preset force positions.

[0070] Specifically, the parameter monitoring module also includes:

[0071] A process parameter monitoring submodule is connected to the tower crane to obtain process parameters during the operation of the tower crane, including the direction of the boom, the load weight of the tower crane, the vibration intensity at several preset positions, and the current height of the attached operating platform device.

[0076] an environmental parameter analysis unit, which is connected to the process parameter monitoring submodule and the environmental parameter monitoring submodule respectively, and is used to compare the monitored wind direction with the boom direction, and to compare the monitored wind speed with a preset wind speed threshold;

[0079] During implementation, the actual implementers can set a preset wind speed threshold based on the performance parameters of the tower crane according to actual conditions; the actual implementers can set a preset force parameter standard based on the performance parameters of the tower crane and the connection position of the balance component according to actual conditions. Preferably, when the tower crane is not working, force analysis is performed on the attachment operating platform device when it is not connected to the attachment balance module and when it is connected to the attachment balance module (including the cases where different numbers of balance components are connected), and the force analysis results are used as the preset force parameter standards.

[0080] The data analysis submodule of the present invention can improve the accuracy of judgment by setting up an environmental parameter analysis unit, a force parameter analysis unit and an analysis and judgment unit for multiple comparative and comprehensive analyses.

[0081] Specifically, the analysis and judgment unit determines whether the attachment balance module triggers the stability adjustment mode based on the comparison results between the monitored wind direction and the boom direction, the comparison results between the monitored wind speed and the preset wind speed threshold, and the comparison results between the force parameters of the attachment operating platform device and the preset force parameters.

[0082] During implementation, if the monitored wind direction is different from the direction of the boom and the monitored wind speed is greater than the preset wind speed threshold, and there is at least one preset force position of the attachment operating platform device whose force parameters do not meet the preset force parameter standards, then it is determined that the attachment balance module triggers the stability adjustment mode.

[0086] An early warning prompt submodule, which is connected to the early warning judgment submodule and is used to output an early warning prompt according to the judgment result of the early warning judgment submodule;

[0087] The early warning prompt submodule outputs an early warning prompt according to the judgment result of the early warning judgment submodule;

[0088] If the data analysis submodule determines that the adhesion balance module triggers the stability adjustment mode, a first warning prompt message is output;

[0089] If the environmental parameter does not meet the preset environmental parameter standard, output a second warning prompt message;

[0090] If the stress parameter does not meet the preset stress parameter standard, a third warning prompt message is output.

[0091] A control analysis submodule, which is connected to the data analysis submodule and is used to adjust the weight and height of the load of the balancing component of the attachment balancing module according to the judgment result of the data analysis module and the current height of the attachment operation platform device;

[0092] Specifically, the control and analysis submodule is connected to the process parameter monitoring submodule. When the attachment balance module triggers the stability adjustment mode, the control and analysis submodule adjusts the weight and height of the load of the balancing component of the attachment balance module according to the current height of the attachment operating platform device, the monitored environmental parameters and the vibration intensity at several preset positions.

[0093] In implementation, the weight WP of the load of the balancing assembly and the height HP of the load are adjusted according to the following formula:

[0094]

[0095] Among them, WB is the standard weight of the balancing component load, WF is the current weight of the balancing component load, HF is the current height of the attached operating platform device, HB is the height of the attached operating platform device corresponding to WB, VF is the current wind speed monitored at the tower position corresponding to the attached operating platform device, and VB is the standard wind speed.

[0096] During implementation, the actual implementers can set the standard wind speed based on the wind speed corresponding to the optimal working state of the tower crane according to actual conditions, and set the standard weight of the balancing component based on the force analysis of the tower crane system based on the working state of the tower crane to make the tower crane system in a balanced and stable state.

[0097] The crane control submodule is connected to the tower crane and the control analysis submodule respectively, and is used to control the working mode of the tower crane according to the height of the load of the balancing component attached to the balancing module.

[0098] The core control module of the present invention can provide early warning prompts to operators in real time by setting the early warning prompt submodule to output early warning prompts to avoid operating errors. By setting the crane control submodule to control the working mode of the tower crane according to the height of the balance component load, the working mode of the tower crane can be adjusted in real time and the working efficiency of the tower crane can be improved.

[0099] Specifically, the crane control submodule determines the working mode of the tower crane according to the height of the load of the balancing assembly attached to the balancing module and a preset load height threshold, wherein:

[0100] If the height of the load is less than the preset load height threshold, the crane control submodule determines that the working mode of the tower crane is the normal mode and uses the rated lifting speed for lifting work;

[0101] If the height of the load is greater than or equal to the preset load height threshold, the crane control submodule determines that the working mode of the tower crane is the variable speed mode, and controls the crane's lifting speed to use the rated lifting speed in the height section below the load and switch to the reduced lifting speed for lifting above the load height section, wherein the reduced lifting speed is less than the rated lifting speed. The reduced lifting speed can be determined according to the height of the load in implementation, and the greater the height of the load, the smaller the reduced lifting speed.

[0102] During implementation, the actual implementer can determine the preset load height threshold by taking the average value after multiple verifications based on actual conditions.

[0103] The crane control submodule of the present invention determines the working mode of the tower crane according to the height of the load of the balancing assembly attached to the balancing module and a preset load height threshold, which can improve the working efficiency of the tower crane and improve the stability of the tower crane.

[0104] The present invention can improve the stability of a tower crane and an attachment operation platform device by setting an attachment balance module. By setting a parameter monitoring module to monitor the environmental parameters during the operation of the tower crane and the force parameters of the attachment operation platform device, the data analysis module can be used to determine whether the attachment balance module triggers a stability adjustment mode and whether an early warning prompt is given, thereby improving the efficiency and accuracy of determining the stability of the tower crane. The core control module can adjust the weight and height of the load of the balance component of the attachment balance module according to the current height of the attachment operation platform device, thereby ensuring the stability of the tower crane and the attachment operation platform device and the efficiency of stability adjustment.
