Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Skeleton air duct folding and unfolding automaton as shown in Figure 1 and Figure 2, primarily of guiding device 1, controls lock set 2 and dismountable control lock protecting sheathing 3, control lock support component 11 4 part composition.
Guiding device 1 is cylindrical shape, and right-hand member is with horn mouth.The left end of guiding device 1 is provided with ring flange 1a for fixing air duct storage device.The sidewall outside weldings of guiding device 1 has control lock support component 11 and dismountable control lock protecting sheathing 3, and dismountable control lock protecting sheathing 3 is locked support component 11 with control and is bolted, and is covered by control lock set 2.
Control lock set 2 to be made up of arc control lock 2a, control handle 2b, anti-malfunctioning part 2c, rotational pin 2d and elastomeric element 2e five parts.Elastomeric element 2e is arranged on and controls on lock support component 11.Control handle 2b is set on rotational pin 2d, controls to have the circular hole passed for rotational pin 2b in the middle part of lock 2b.Control handle 2b is hooked on elastomeric element 2e by the arc notch 2f arranged on the left of outer end, during to ensure that control handle 2b is rotated counterclockwise, elastomeric element 2e is controlled in arc notch 2f all the time, only have when controlling lock and being rotated counterclockwise, elastomeric element 2e side and control handle 2b collide, and hinder control lock to rotate to control lock applying reciprocal mechanical resistance.The outboard end that the medial extremity of control handle 2b and arc control to lock 2a is fixed together, the axis of rotational pin 2d and the axes normal of guiding device 1, the two ends of rotational pin 2d are arranged on and control on lock support component 11, it is curved and stretch into the inner chamber of guiding device 1 that arc controls the medial extremity of lock 2a, when arc control lock 2a turns clockwise for the center of circle with rotational pin 2d, arc controls the inner chamber that lock 2a can leave guiding device 1.Anti-malfunctioning part 2c is connected in the right-hand member of control handle 2d, and the tip portion of anti-mistake parts 2c becomes to be obliquely installed with control handle 2b down.
Arc controls lock 2a, control handle 2b, anti-malfunctioning part 2c is solidly fixed, and when arc controls lock 2a by External Force Acting, drives control handle 2b, anti-malfunctioning part 2c to rotate around control pin 2c together.
Preferably, arc controls lock 2a and control handle 2b and is together by a threaded connection, and anti-malfunctioning part 2c and control handle 2d is together by a threaded connection and the adjustable length of anti-malfunctioning part 2c.Guiding device 1 is designed to horn mouth, and mainly conveniently skeleton air duct is recovered in air duct storage device.
During installation, composition graphs 3---shown in Fig. 5, skeleton air duct folding and unfolding automaton 8 is fixedly installed togather by ring flange and air duct storage device 7, and the left end of air duct storage device 7 is fixedly installed togather with the right-hand member of the deduster 5 that can move left and right.During work, drive air duct storage device 7, skeleton air duct folding and unfolding automaton 8 move left and right by deduster 5 move left and right together.The left end of skeleton air duct 6 is fixed on the right-hand member of deduster 5, and the right-hand member of skeleton air duct 6 is connected with the left end of light air cylinder 9, and the right-hand member of light air cylinder 9 is connected with the changeless pressure fan 10 in position, and wind direction from right to left.The object of skeleton air duct folding and unfolding automaton 8 realizes skeleton air duct 6 automatic deploying and retracting in air duct storage device 7.In dust removal process, when deduster 5 moves to left, need at leisure skeleton air duct 6 to be pulled out air duct storage device 7; When deduster 5 moves to right, need freely skeleton air duct 6 to be recovered in air duct storage device 7.
The course of work and principle as follows:
When deduster 5 drives air duct storage device 7, when skeleton air duct folding and unfolding automaton 8 is moved to the left together, to pull out from skeleton air duct folding and unfolding automaton 8 at the effect lower skeleton air duct 6 of light air cylinder 9 pulling force, because skeleton air duct 6 circumference is uneven, skeleton air duct 6 outer surface will inevitably collide anti-malfunctioning part 2c output one pulling force to the right, the arc in control lock set 2 is made to control lock 2a, control handle 2b, anti-malfunctioning part 2c together with rotational pin 2d for the center of circle rotates counterclockwise, in the process rotated, control handle 2b will collide with elastomeric element 2e and generates an elastic force contrary with wind direction, rotate counterclockwise to hinder the rotatable parts controlling lock set 2, control the anglec of rotation of lock set 2 will increase gradually along with skeleton air duct 6 moves right, the elastic force that elastomeric element 2e acts on control handle 2b also will constantly increase, skeleton air duct 6 only overcomes the control that the elastic force constantly increased could depart from control lock set 2 and is drawn out.When skeleton air duct 6 is pulled out to preseting length, system will be reported to the police, and remind driver to stop immediately, if driver forgets parking, along with skeleton wind 6 is constantly drawn out, the power supply automatically cutting off deduster running part prevents skeleton air duct 6 to be pulled off by system.
When deduster 5 drive air duct storage device 7, skeleton air duct folding and unfolding automaton 8 move right together time, skeleton air duct 6 circumferential surface is uneven can to supplying distinguished and admirable formation one thrust left, the arc in control lock set 2 is made to control lock 2a, control handle 2b, anti-malfunctioning part 2c with rotational pin 2c for the center of circle rotates clockwise, turn clockwise and be one because arc controls lock 2a and rotate freely that its power-assisted of process is very little can be disregarded in flicker, so skeleton air duct 6 can easily enter in air duct storage device 7 under thrust, do not need manually to push away to the inside.
This device can carry out the skeleton air duct designing minimum energy folding and unfolding 15m as required.In addition, by the diverse location hooking elastomeric element 2e of design con-trol handle 2b upper semi-circle v notch v, change control handle 2b and arc control the ratio of the brachium locking 2a two stress points, and the elasticity power-assisted formed will change, and can adjust as required.
