It is appreciated that screw mandrel 123 can be two, is respectively arranged on the both sides in compartment 2.First nut 121 and the second nut 122 spiral shell respectively are located on two screw mandrels 123.Two screw mandrels 123 of synchronous axial system, drive the first nut 121 and the second nut 122 to be synchronized with the movement, make first nut the 121, second nut 122 synchronize closer or far from.
In other embodiments, driver element also can use the following two kinds embodiment.
In one embodiment, driver element includes the first gear, the second gear, the first tooth bar and the second tooth bar.First gear and the engagement of the first tooth bar.Second gear and the engagement of the second tooth bar.First tooth bar and the second tooth bar are parallel to each other and are distributed in and be perpendicular to before and after compartment on direction.First tooth bar and the second tooth bar end with two expansion links of telescopic arm one end respectively is connected.First gear, the second gear are mutually in step, rotate backward, make the first tooth bar and the second rack synchronous is close to each other or away from, drive telescopic arm one end two expansion links end synchronize close to each other or mutually deviate from realize telescopic arm stretch.
Specifically, the first tooth bar and the second tooth bar can be located at compartment foremost relatively, but are not limited to be located at compartment foremost.First tooth bar and the second tooth bar can also interlaced setting, the first tooth bar and the second tooth bar respectively with the end with two expansion links of telescopic arm one end, it is also possible to realize the first tooth bar and the purpose of the second rack synchronous driving expansion link.It is perpendicular to before and after compartment on direction as long as the first tooth bar and the second tooth bar are distributed in.
First gear, the second gear are mutually in step rotation, it is desirable to the first gear and the second gear start simultaneously at rotation, and ensure can be reached simultaneously by the first gear, separately-driven first tooth bar of the second gear, the second tooth bar, synchronized motion.
In another embodiment, driver element includes that two edges are perpendicular to direction synchronization, the opposing piston rod moved before and after compartment.Two piston rods are connected with the end of two expansion links being positioned at telescopic arm one end respectively and drive it Tong Bus close to each other or mutually deviate from that to realize telescopic arm flexible.
It is appreciated that, two piston rods can be located at the both sides in box width direction the most relatively, opposing can also be located at the middle part in box width direction, all can make close to each other between two piston rods or mutually deviate from, it is achieved the end of two expansion links synchronizes close to each other or mutually deviates from.
Two piston rods can be arranged on two independent hydraulically controlled cylinders or two independent pneumatic cylinders, it is also possible to is arranged on a two-way hydraulic cylinder or a two-way cylinder.
Please refer to Fig. 2, driver element also includes travel switch 126.On the walking path of the end that expansion link 113 is located at by travel switch 126, travel switch 126 controls the stroke of push rod 13.The end of expansion link 113 is along being perpendicular to the path walking in direction before and after compartment 2.When push rod 13 moves to front end or the rear end in compartment 2 when, illustrate that top cover is the most fully open or whole capping compartment 2, then the end stop motion of expansion link 113, thus push rod 13 stop motion.The most in the present embodiment, travel switch 126 is that mechanical type touches travel switch.Travel switch 126 is located on screw mandrel 123, and first nut the 121, second nut 122 touches travel switch 126, to control the stroke of push rod 13.The stroke two ends of first nut the 121, second nut 122 are located at by travel switch 126.When the first nut 121 or the second nut 122 drive to the two ends of stroke, travel switch 126 can be touched, thus reach to control the purpose of push rod 13 stroke.
It is appreciated that travel switch 126 can also be for photo-electric travel switch.Photo-electric travel switch can be arranged on the front end in compartment 2, it is also possible to is located on screw mandrel 123, as long as the end of expansion link 113 can trigger photo-electric travel switch in motor process, it is possible to realizes controlling the purpose of push rod 13 stroke.
Further, travel switch 126 can omit, and can realize controlling the first nut 121 and stroke of the second nut 122 by the length arranging the first screw thread and the second screw thread.When first nut the 121, second nut 122 moves to the two ends of the first screw thread, the second screw thread respectively when, then push rod 13 makes top cover fully open or all capping compartment 2, push rod 13 stop motions, can also reach to control the purpose of push rod 13 stroke equally.
Push rod 13 is slidably located on the sidewall in compartment 2 and is connected with top cover.Push rod 13 axially the most vertical with direction before and after compartment 2.Push rod 13 is connected with telescopic arm 11, and with telescopic arm 11 flexible and along direction walking before and after compartment 2, make top cover capping or open compartment 2.
Push rod 13 offers chute 131 vertically, and the free end near two expansion links 113 of push rod 13 is slidably contained in chute.The opening of chute is in the same plane with expansion link 113, facilitates the free end of expansion link 113 along slide.
It is appreciated that the free end of expansion link 113 can also be sheathed on push rod 13, it is achieved the free end of expansion link 113 slides along push rod 13.Push rod 13 can be connected with the end of telescopic arm 11, it is also possible to is connected with the middle part of telescopic arm 11, moves with telescopic arm 11 as long as being capable of push rod 13.
The carriage head cover driving means 10 of present embodiment also includes two tracks being oppositely arranged 14.Two tracks are respectively arranged in the two opposite side walls in compartment 2 along direction before and after compartment 2.Concrete the cross section of track 14 is I-shaped in the present embodiment, and track 14 is arc convex with the contact surface of roller 15.When stone, dust fall on the surface of track 14 when, arc convex can make stone, dust Automatic-falling, prevents track 14 from blocking.Track 14 is the track meeting national standard, and goods impact is not afraid of by track 14, and can maintain a long-term stability operation.
The two ends of push rod 13 are provided with roller 15, and roller 15 moves along track 14.Roller 15 is provided with limiting section 151, and limiting section 121 abuts against with the medial wall of track 14.Limiting section 121 is possible to prevent push rod 13 axially to shake along it, prevents roller 15 from derailing.
Equally, the two ends of bracing piece 114 also are provided with roller 15.Roller 15 rolls along track 14, drives bracing piece 114 to move along track 14.
In above-mentioned carriage head cover driving means 10, push rod 13 motion makes top cover open or covers compartment 2.Due to transmission mutual between each telescopic joint 110 of above-mentioned telescopic arm 11, and the change of the angle number of degrees just can make the length of telescopic joint 110 change between two expansion links 113 of each telescopic joint 110, the motion therefore in two expansion links 113 of same telescopic joint 110 is to synchronize.And two expansion links 113 are connected with push rod 13 respectively, then the stress point between telescopic arm 11 and push rod 13 has two, it is ensured that the uniform force of push rod 13, make push rod 13 easy motion.
