Wherein tablet 41 is in semi-circular, and fixed link 42 is perpendicular to 41 one side of tablet is arranged at, and in specific implementation process, first cuts
The extending direction that yoke 31, the second scissor arms 32 relatively rotate shaft 30 is parallel with the extending direction of fixed link 41.
In order to be better understood from the utility model, the carrying out practically mode of the utility model is made as detailed below below.
Refering to what is shown in Fig. 1, Aerial Work LT has motor 5 and control module（It is not shown in figure）, wherein motor 5 drives
First scissor arms 31, the second scissor arms 32 relatively rotate, control module can receiving angle inductive component 4 inductive signal and control
The operating of motor 5.
Specifically, during 2 elevated height of roof platform of Aerial Work LT, motor 4 drives scissor arms group by promotion program work
Make：First scissor arms 31, the second scissor arms 32 are located at pedestal 1（Or roof platform 2）The both ends of one side are gradually drawn close, 2 position of roof platform
It gradually rises；In 2 elevation process of roof platform, the first scissor arms 31 have certain angular turn, due to the first scissor arms 31,
The extending direction that two scissor arms 32 relatively rotate shaft 30 is parallel with the extending direction of fixed link 41, is fixed on the first scissor arms 31
Fixed link 42 can drive tablet 41 to rotate identical angle with the first scissor arms 31, and in the process, angle inductive component 4 is real
When sense the angle of the first scissor arms 31 rotation, and the angle signal of sensing is transferred to control module；When angle inductive component 4
When sensing the first extreme rotational angle, control module exports the instruction that stops operating to motor 5, so that scissor arms group 3 stops
Promote the height of roof platform 2.
Refering to what is shown in Fig. 4, it shows the position of 41 relative level of tablet when roof platform 2 is promoted to highest position
Schematic diagram, specifically, direction shown in reference chart, between the plane 410 and horizontal plane where 41 both ends of semi-circular tablet
Relative angle can be used as the first extreme rotational angle for α.
In Aerial Work LT specifically raises operational process, when angle inductive component 4 senses the first extreme rotational angle
When spending, Aerial Work LT is allowed to promote certain buffer height again.Specifically, i.e., angle inductive component 4 senses first
During extreme rotational angle, control module exports motor 5 instruction that stops operating, but motor 5 is allowed to continue to turn under effect of inertia
A dynamic fixing turn, so as to continue to lift up the height of roof platform 2 to a certain extent.
With reference to Fig. 5, Fig. 6, Fig. 7, show that the roof platform 2 of the utility model Aerial Work LT is reduced to extreme lower position
The view at place.When the roof platform 2 of Aerial Work LT highly reduces, motor 4 drives scissor arms group by reduction program work：
First scissor arms 31, the second scissor arms 32 are located at pedestal 1（Or roof platform 2）The both ends of one side are gradually distance from, and 2 position of roof platform is gradual
It reduces；During the reduction of roof platform 2, the first scissor arms 31 have certain angular turn, since the first scissor arms 31, second are cut
The extending direction that yoke 32 relatively rotates shaft 30 is parallel with the extending direction of fixed link 41, is fixed on the first scissor arms 31 and fixes
Bar 42 can drive tablet 41 to rotate identical angle with the first scissor arms 31, and in the process, angle inductive component 4 is felt in real time
The angle that the first scissor arms 31 is answered to rotate, and the angle signal of sensing is transferred to control module；When angle inductive component 4 senses
During to the second extreme rotational angle, control module exports the instruction that stops operating to motor 5, so that scissor arms group 3 stops reducing
The height of roof platform 2.
Refering to what is shown in Fig. 7, it shows the position of 41 relative level of tablet when roof platform 2 is reduced to its lowest position
Schematic diagram, specifically, direction shown in reference chart, between the plane 410 and horizontal plane where 41 both ends of semi-circular tablet
Relative angle can be used as the second extreme rotational angle for β.
In Aerial Work LT specifically reduces operational process, when angle inductive component 4 senses the second extreme rotational angle
When spending, Aerial Work LT is allowed to reduce certain buffer height again.Specifically, i.e., angle inductive component 4 senses second
During extreme rotational angle, control module exports motor 5 instruction that stops operating, but motor 5 is allowed to continue to turn under effect of inertia
A dynamic fixing turn, so as to continue to reduce the height of roof platform 2 to a certain extent.
In the operational process of Aerial Work LT, plane 410 where 41 both ends of semi-circular tablet and horizontal plane it
Between relative angle changed in the range of α ~ β, control module can be effectively to the lifting row of Aerial Work LT according to this scope
Journey is defined.Based on the angle inductive component 4 in the utility model in angle detection process without Mechanical Contact, this is effectively
The damage probability for reducing angle inductive component 4.
It is, of course, understood that the tablet 41 in the utility model may be set to be other shapes, do not limit to
In semicircular configuration.
