The variable-pitch electric cylinder is arranged below the floor of the stabilizing platform main body, and the fixed end is movably connected with the floor of the stabilizing platform main body.

The control box generates control instructions of the variable-amplitude electric cylinder, the variable-pitch electric cylinder and the suction plate device based on the lifting, variable-amplitude and rotation data. The movable end of the variable-amplitude electric cylinder is movably connected with the movable end of the variable-pitch electric cylinder so as to realize linkage of the variable-pitch electric cylinder and the variable-pitch electric cylinder in the rotating process.
The solution according to the invention is further illustrated below by means of a specific application example.
As shown in fig. 1-2, the present invention comprises a stable platform main body, an amplitude variable electric cylinder, a variable pitch electric cylinder, a magnetic suction plate, a control box, a signal acquisition device, a lithium battery power supply, a lead and other auxiliary devices. Wherein, the variable-pitch electric cylinder is arranged under the stable platform floor. The lower margin can support stable platform, plays the effect of the electronic jar of protection displacement. The four steel cables are connected to the same steel ring, and the steel ring bears all the weight of the stable platform and is used for being connected with a lifting hook of external hoisting equipment. The amplitude-variable electric cylinder is arranged in the middle of the front end face of the stable platform.
The amplitude-variable electric cylinders are three identical electric cylinders, the tail ends of the amplitude-variable electric cylinders are connected to the electric cylinder fixing seat on the front end face of the stabilizing platform through a shaft, and the electric cylinders are guaranteed to freely rotate around the shaft after being installed. The mounting hole at the head end of the variable-amplitude electric cylinder is connected with a fixed seat on a variable-pitch electric cylinder rigid body through a shaft, and the electric cylinder can freely rotate after being mounted. The electric cylinder has a self-locking function, and the state of the electric cylinder cannot be changed due to the influence of external force when no electric signal is input. The same electronic jar of three model is adopted to the electronic jar of displacement, and electronic jar is terminal to be connected with the fixing base under the stable platform main part floor through the axle, and electronic jar can use the axle to rotate as the center, and the cylinder body head end is provided with becomes the electronic jar mount pad of width of cloth for become width of cloth electronic jar be connected. The variable-pitch electric cylinder is connected with a magnetic suction plate, the magnetic suction plate is connected with the variable-pitch electric cylinder through a shaft in the same way, the axis of the shaft is parallel to other shafts, and the magnetic suction plate can rotate freely around the shaft.
The magnetic attraction plate is three high-performance electromagnets. When the magnetic suction plate receives an electric signal, a strong magnetic field is generated to be closely attracted with the metal wall surface of the ship body, and after the electric signal disappears, the magnetic force disappears, the magnetic suction plate breaks away from the metal wall surface, and at the moment, the transfer operation of the stable platform can be carried out. Preferably, the magnetic suction plate can be replaced by a rubber glass suction cup for adsorbing the glass outer wall of the high-rise building, and the invention is developed and applied to the cleaning, maintenance and other works of the glass outer wall of the high-rise building.
The control box is connected to the stable platform floor through bolts and is matched with the signal acquisition device for use. The signal acquisition device is an integrated small module, is arranged on an external hoisting device, and can convert the actions of hoisting, amplitude variation, rotation and the like of the hoisting device into electric signals to be output to the control box. The main functions of the control box are as follows: 1. the electric signal that signal acquisition device sent can be received, the action of discerning outside hoisting accessory. 2. The actions of the variable-amplitude electric cylinder, the variable-pitch electric cylinder and the magnetic suction plate are controlled, and the balance of the stable platform is kept constantly.
Preferably, the present invention employs multiple power supply means. (1) The electric cylinder can be operated by supplying power through the lithium battery; (2) an umbilical cable can be adopted for power supply, the umbilical cable and the sling run downwards, and power is supplied by an external power grid; (3) the power can be supplied directly from the ground or the cabin. The wire is directly from the steady platform down, utilizes ground power supply to supply power for the steady platform.
Compared with a common stable platform, the stable platform has the functions of shaking prevention, alternate crawling of three feet and the like, and the distance between the stable platform and the wall surface can be adjusted according to actual working requirements. The weight of the stable platform is mainly borne by the hoisting device, and the electric cylinder only plays a supporting role and is not used for bearing.
And realizing the anti-shaking function of the stable platform. The stable platform belongs to an unpowered device, can not move autonomously, and needs to move under the traction of an external hoisting device. The anti-shaking function of the stable platform is realized by the combined action of the variable-amplitude electric cylinder, the variable-pitch electric cylinder and the magnetic suction plate. After the stabilizing platform reaches the working wall surface, the length of the two groups of electric cylinders is adjusted by manually pressing a button on the control box, the magnetic suction plates are conveyed to reach the surface of the metal wall surface, the circuit of the magnetic suction plates is switched on at the moment to generate magnetic force, the magnetic suction plates are adsorbed on the wall surface, and the three magnetic suction plates can effectively inhibit the stabilizing platform from shaking to achieve the anti-rolling effect.
And realizing the function of alternately crawling the three feet of the stable platform. As shown in fig. 3, the stabilizing platform can be automatically shifted according to the lifting and falling of the crane. The three-foot alternate crawling function is mainly realized by cooperative work of the signal acquisition device and the control box, when the signal acquisition device acquires lifting and other movements of the crane, an electric signal can be sent to the control box, and the control box can control actions of the six electric cylinders according to the types of the signals. For example, when the crane contracts the sling to enable the stabilizing platform to generate a trend of upward movement, the amplitude-variable electric cylinder extends, the stabilizing platform can move upwards within a certain range, and when the distance exceeds a certain range, the requirement that the stabilizing platform is stretched by the aid of the electric cylinder cannot be met. At the moment, the control box can control one of the three magnetic suction plates to be powered off to enable the magnetic suction plate to lose magnetic force, the corresponding amplitude and variable-pitch electric cylinder is completely retracted into the cylinder body, the variable-pitch electric cylinder is extended out after the retraction process is completed, then the magnetic suction plate power supply is automatically switched on to enable the magnetic suction plate power supply to be adsorbed on the wall surface again, and the three magnetic suction plates sequentially perform the action to realize the transposition of the magnetic suction plates, so that the position of the stable platform is changed. In the process, two magnetic suction plates are always ensured to be in a working state at the same time, so that the stable platform can still realize anti-shaking when the position is changed. The process realizes the function of three-foot alternate crawling of the stable platform.
And realizing the pitch changing function of the stable platform. In actual production, according to the needs of different work, the distance requirement between stable platform and the wall is also different, and three electronic jar accessible manual control button carries out the synchronization action, as shown in fig. 4, when the electronic jar of control stretches out, just can drive stable platform and keep away from the wall, and when the electronic jar of control was withdrawed, then can make stable platform press close to the wall to this adjusts the distance between stable platform and the wall. Three magnetic suction plates of the stabilizing platform can not work at the same time. When the two suction plates work at different times, any one suction plate can be controlled to work independently, and any two suction plates can also work in a matching way, as shown in figure 5. In some places with low anti-shaking requirements, the suction force of one or two suction plates can meet the requirements, and three suction plates are not required to be started, so that the time for laying the stable platform is saved, and the efficiency is improved. In some workplaces, three suction plates cannot be used for adsorbing the wall surface at the same time, and at the moment, any two suction plates can also meet the shaking prevention requirement when working at the same time.
The operator can transfer the crane in a stable platform in a large range. The control box of the stabilized platform can realize intercommunication interconnection with an external crane remote control module, so that remote control of an external crane can be realized, and further large-scale transfer of the stabilized platform in the stabilized platform is realized.
Personnel in the stable platform need tie the safety rope on the loop wheel machine lifting hook along with, prevent that the platform accident from droing, hindering personnel.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
