Abstract
The invention provides an electromechanical interlocking mechanism for a mast type aerial work platform landing leg. The electromechanical interlocking mechanism comprises a landing leg body assembly, a landing leg pin shaft, a limiting switch, an inner hexagon screw, a nut, a flat key and a snap spring. The landing leg body assembly is connected to the landing leg pin shaft. The flat key is arranged in the landing leg pin shaft. The snap spring is located on the landing leg pin shaft. The inner hexagon screw passes through a through hole, penetrates the landing leg pin shaft and is screwed on the landing leg pin shaft through the nut. By means of the electromechanical interlocking mechanism, an operator can be reminded when the landing leg is not in the effective opened state.
Description
Technical field
The present invention relates to a kind of electromechanical linkage mechanism, in particular it relates to a kind of column type overhead operation platform supporting leg is dynamo-electric
Interlocking gear.
Background technology
Commonly there is no the supporting leg of electromechanical linkage mechanism, in folding and when opening, easily affected by operating personnel and may nothing
Method is in correct position, thus bringing possible danger.
Content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of column type overhead operation platform supporting leg is dynamo-electric
Interlocking gear, it can remind operating personnel when supporting leg is not on effective open mode.
According to an aspect of the present invention, provide column type overhead operation platform supporting leg electromechanical linkage mechanism, its feature exists
In it includes supporting leg body assembly, leg pin, limit switch, soket head cap screw, nut, flat key, jump ring, and supporting leg body is total
Become to be connected on leg pin, flat key is built in leg pin, jump ring is located on leg pin, and soket head cap screw passes through through hole
Through leg pin and by nut on leg pin.
Preferably, described leg pin there is screw thread.
Preferably, described limit switch includes distant bar, distant bar roller, and rocker roller is located at rocking bar top.
Compared with prior art, the present invention has following beneficial effect：The present invention can be not on effectively in supporting leg
Operating personnel are reminded during open mode.
Brief description
The detailed description with reference to the following drawings, non-limiting example made by reading, the further feature of the present invention,
Objects and advantages will become more apparent upon：
Fig. 1 is the planar structure schematic diagram of the present invention.
Fig. 2 is the supporting leg folding state schematic top plan view of the present invention.
Fig. 3 is the supporting leg open mode schematic top plan view of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, some deformation can also be made and improve.These broadly fall into the present invention
Protection domain.
As shown in Figure 1 to Figure 3, the present invention includes supporting leg body assembly 1, leg pin 2, limit switch 3, soket head cap screw
4th, nut 5, flat key 6, jump ring 7, supporting leg body assembly 1 is connected on leg pin 2, and flat key 6 is built in leg pin 2, card
Spring 7 is located on leg pin 2, and soket head cap screw 4 passes through leg pin 2 by through hole and is tightened in leg pin 2 by nut 5
On.
The operation principle of the present invention is as follows：, when opening supporting leg, leg pin can be in the drive of flat key for operating personnel
Under rotate together, thus driving the rotation of soket head cap screw, when soket head cap screw turns to angle at the end, promote spacing
Switch rocker roller motion, so that distant bar rotates, adjusts the position of each part, realizes supporting leg and open can rising when putting in place
Signal transmission to main line system.
Screw thread 21 is had on leg pin 2, so can be with increasing friction force, firm part.
Limit switch 3 includes distant bar 31, distant bar roller 310, and rocker roller 310 is located at rocking bar 31 top, so operates it
Get up more convenient.
In sum, the present invention can remind operating personnel when supporting leg is not on effective open mode, and structure letter
List is it is easy to manufacturing and producing.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various modifications or modification within the scope of the claims, this not shadow
Ring the flesh and blood of the present invention.
