Detailed Description
The present invention will be further explained with reference to the drawings attached to the specification.
As shown in fig. 1 to 3, the work platform capable of moving along a horizontal linear track includes a first rotating device 01, a turntable 02, an arm frame 03, a second rotating device 04, and a work platform 05. The first rotating device 01 drives the rotary table 02 to rotate by means of a group of slewing bearings and a gear transmission system and a speed reduction motor, and drives the arm support and the operation platform to rotate around a first vertical shaft, so that the arm support rotates in the horizontal direction. The arm support 03 comprises an amplitude variation arm 31, a telescopic arm 32 and a swing arm 33, wherein the amplitude variation arm 31 is assembled on the rotary table 02 and driven by an amplitude variation oil cylinder 311 to swing up and down, the telescopic arm 32 is assembled on the amplitude variation arm 31 and driven by a telescopic oil cylinder 321 to extend and retract, and the swing arm 33 is assembled at one end of the telescopic arm 32 far away from the rotary table and driven by a swing arm oil cylinder 331 to swing up and down, so that the arm support can perform distance in the horizontal direction (telescopic action) and height in the vertical direction (amplitude variation action). The second rotating device 04 is arranged at one end of the swing arm 33 far away from the rotary table 02, and the working platform 05 is assembled on the second rotating device 04; the second rotating device drives the working platform to rotate around the second vertical shaft by a group of rotating supports and a gear transmission system and driven by a speed reducing motor, so that the working platform rotates in the horizontal direction.
In particular, the angular velocity of the rotation of the turntable 02 about the first vertical axis is equal and opposite to the angular velocity of the rotation of the work platform 05 about the second vertical axis. The reduction ratios of the gear transmission systems in the first rotating device and the second rotating device are basically consistent, so that the speeds of the motors with the same rotating speed output to the first rotating device and the second rotating device are basically the same, and the rotating speeds of the two reducing motors are opposite, so that when the two reducing motors work simultaneously, the rotation of the arm support in the horizontal direction and the rotation of the operation platform in the horizontal direction are mutually offset, and the position change of the operation platform in the horizontal direction is realized, and the posture of the operation platform is inconvenient. Because the loads of the first rotating device and the second rotating device are different, the first rotating device and the second rotating device are provided with motors with different powers. Moreover, controllers can be respectively configured for the two motors to control the starting and stopping rotating speeds of the motors so as to adjust the speed difference caused by mechanical design errors. Similarly, the angular velocity of the luffing jib swinging up and down is equal to and opposite to the angular velocity of the swing arm swinging up and down. Therefore, the attitude of the operation platform is kept unchanged during the synchronous up-down swinging amplitude variation.
When the telescopic arm support works, the rotation in the horizontal direction, the up-and-down swing in the vertical direction and the telescopic synchronous action of the arm support can be controlled.
As shown in fig. 5-6, when the position is adjusted, the work platform 05 will move away from or close to the work surface due to the rotation in the horizontal direction, and only the relative movement of the boom 03 will compensate for this distance change. When the operation platform is far away from the operation surface, the telescopic action of the arm support extends out, and meanwhile, because the arm support changes in the vertical direction of the platform caused by extension, the arm support needs to swing up and down in the vertical direction to perform amplitude variation action and descend, so that the height position of the operation platform at the tail end of the arm support is adjusted. When the working platform is close to the working face, the action is opposite to the action. In the compensation process, through program setting, the relation between the angle value of the rotation of the arm support in the horizontal direction and the amplitude value of the up-and-down swing of the arm support in the vertical direction is calculated, a required action signal is sent, and the action of the corresponding arm support is started through hydraulic pressure.
Further, a follow-up oil cylinder 34 is connected between the amplitude variation arm 31 and the rotary table 02; the second rotating device 04 is arranged at one end, far away from the rotary table, of the swing arm 03 in a swinging mode, and a leveling oil cylinder 35 is connected between the second rotating device 04 and the swing arm 03; the leveling oil cylinder is communicated with the oil circuit of the servo oil cylinder, and the size of the leveling oil cylinder is consistent, so that oil quantity complementation is realized. When the variable-amplitude arm works, the leveling oil cylinder ensures that the workbench is always kept horizontal, and the follow-up oil cylinder extends or retracts along with the change of the angle of the variable-amplitude arm.
For stable structure, the atress is balanced, and the swing arm is two and these two swing arms constitute two parallel sides of parallelogram.
As shown in fig. 4, the luffing cylinder 311, the telescopic cylinder 321, the swing arm cylinder 331, the first slewing device 01, and the second slewing device 04 are controlled by a controller. The controller controls the actions of the amplitude variation oil cylinder, the telescopic oil cylinder, the swing arm oil cylinder, the first rotating device and the second rotating device, so that the rotation action (rotation of the arm support in the horizontal direction), the swing action (rotation of the operation platform in the horizontal direction), the telescopic action (telescopic action of the arm support), the amplitude variation action (up-and-down swing of the arm support in the vertical direction) and the translation selection are realized. In addition, in order to avoid the situation that the working platform encounters an obstacle or exceeds a set range during displacement, a left stopper, a right stopper, a left obstacle sensor, a right obstacle sensor and a front obstacle sensor which are controlled by a controller are arranged on the working platform, and the stoppers and the sensors sense positions or obstacles, so that the working platform stops moving when reaching the corresponding positions.
The controller can process the output of the rotation action and the output of the swing action in different states, and the rotation and the swing can be respectively carried out or the rotation and the swing can be associated to carry out translation. When the platform swings to a certain angle, the limit is limited or an obstacle sensor arranged at the platform obtains a signal, and the direction is rotated in a related mode to stop. The direction of the associated rotation coincides with the set direction of the turning motion. When the platform needs translation, the translation or linear track action on the horizontal plane can be realized by increasing the amplitude compensation of the arm support while the platform is in associated rotation.
According to the technical scheme, the problem that the operation efficiency is low due to repeated parking of the lifting working platform in horizontal large-range operation is solved, and the instability of manual operation adjustment translation of the working platform and the uncertainty of the angle are avoided by combining the control of the controller.
The working platform capable of moving along the horizontal linear track is suitable for being configured on various lifting working platforms to work.
