Problems solved by technology

[0003] At present, the operating platforms used on machine tools and equipment mainly include platform ladders. This kind of ladder adopts welding form, which is only convenient for the machine tools with fixed height. Once the position and height of the workpiece on the machine tool change, the platform ladder must be moved. Or replace the platform ladder; in addition, use a liftable platform. Once the platform rises to a certain height, the platform must be lowered when it comes down again. When it is necessary to go up and down frequently, this kind of platform is extremely inconvenient
[0004] Now let’s take the column and beam equipment commonly used in the market as an illustration. The working head is arranged at the end of the beam. When processing the workpiece, the person is between the equipment and the workpiece, and the space is very limited. At the top, the working part of the person also needs to be raised. At present, this common solution is to make a platform to follow the beam to move up and down, but it is inconvenient for people to go up and down after it is raised. Connecting to the beam will affect the stroke of the beam and reduce the working range of the equipment

Embodiment 1

[0057] First, determine the number of floors of the platform according to the actual needs of the workpiece. Here, the platform is set to include the first floor 4 of the ladder and the second floor 7 of the ladder. The platform is locked by the self-locking device 11 at the initial position, and the operating height is assumed to be the second floor 7 of the ladder. high.

[0058] The controller 2 controls the work of the cylinder 9, the cylinder rod stretches out, the thrust of the cylinder 9 is greater than the elastic force at the hook 113 of the self-locking device 11, and pushes the first floor 4 of the ladder and the second floor 7 of the ladder to leave the self-locking device 11, the first floor of the ladder 4 and the ladder The second floor 7 rotates around the column 1 through the rotating part 10. After rotating 90 degrees relative to the initial position, the stroke of the cylinder 9 reaches the maximum. This signal is fed back to the controller 2, and the control...

Embodiment 2

[0061] The same places as in Embodiment 1 will not be repeated. When the working height only needs to be the height of the first floor 4 of the ladder, the second floor 7 of the ladder that does not participate needs to be rotated back to the initial position. The controller 2 controls the cylinder rod of the telescopic drive 808 to shrink, and the cylinder The rod drives the telescopic plate 801 to retract, and the bracket 802 fixedly connected to the telescopic plate 801 closes the curved rail 807 through the pin shaft 803 .

[0062] Pull out the pin shaft 803 from the pin hole 6 of the second floor 7 of the ladder, the controller 2 controls the cylinder 9 of the second floor 7 of the ladder to extend, and the second floor 7 of the ladder rotates around the column 1 through the rotating part 10, and rotates 90 degrees relative to the working position. After a certain angle, the stroke of the cylinder 9 at the bottom of the second floor 7 of the ladder reaches the maximum, and...

Embodiment 3

[0065] The same places as those in Embodiments 1 and 2 will not be repeated. When the first floor 4 of the ladder returns to the initial position, the controller 2 first controls the contraction of the cylinder 9 of the first floor 4 of the ladder, and locks the hasp lock 304 on the first floor 4 of the ladder from the locked position. The hasp hook 305 of the device is taken off, and the controller 2 controls the cylinder 9 of the ladder one floor 4 to stretch out.

Abstract

The invention discloses a rotary extension-type ladder device and belongs to the field of operation platforms. The rotary extension-type ladder device comprises a column, wherein at least one layer of platform is arranged on the column, the number of layers can be adjusted flexibly according to different working heights, actuators are arranged on the column and drive the platforms to rotate around the column, a self-locking device and a locking device are arranged on the column, an extension part is arranged on each platform, the working space of the platform can be increased, when the height of a workpiece is lower, the rotary extension-type ladder device which doesn't participate in working rotates to the other side of equipment completely, up-and-down motion can be realized by the aid of the ladder, the problem that the working platforms are inconvenient to carry is solved, and the utilization of the processing spaces is further improved by rotation and extension of the platforms.

Description

technical field [0001] The invention relates to the field of operating platforms, in particular to a rotating and telescopic ladder climbing device. Background technique [0002] In the working state of some equipment, operators need to work at different heights. Due to the different sizes of workpieces and different working heights, and the need to frequently go up and down, take tools, detect workpieces, adjust equipment parameters, etc., the space of this part of equipment is often limited, so There is no good way to achieve both the use requirements and the equipment requirements. [0003] At present, the operating platforms used on machine tools and equipment mainly include platform ladders. This kind of ladder adopts welding form, which is only convenient for the machine tools with fixed height. Once the position and height of the workpiece on the machine tool change, the platform ladder must be moved. Or replace the platform ladder; adopt a liftable platform in addit...
