The second described bar 1402 is being provided with sphenocephaly 1403 with the both sides of the contact portion of sealing strip 1504.
In the use of the present invention,
During original state, action bars 14 is promoted so that retainer ring 1301 departs from the space between driving gear 7 and the collar 10, connects
Head power supply, motor 5, which rotates, can drive straddle truck to be moved on track 4, when being moved to the place of handling goods, promote again
Action bars 14, retainer ring 1301 is pushed in the space between driving gear 7 and the collar 10, the now rotation of motor 5 can not band
Driven portal is hung on track 4 and moved, and can ensure personal security during handling goods.
In the state that motor 5 can drive straddle truck to move, prism 502 rotates, and prism 502 extrudes steel ball 12, makes steel
Pearl 12 presses to driving gear 7, in the case where motor shaft 501 constantly rotates, the continuous extrusion driving gear 7 of steel ball 12 so that main
Moving gear 7 rotates simultaneously under the frictional force effect of steel ball 12 with motor shaft 501, that is, realizes that motor 5 drives road wheel 6 in track
Moved on 4, the rotating situation of motor 5 is identical, and the movable of straddle truck can be achieved.
When retainer ring 1301 is inserted into the space between driving gear 7 and the collar 10, motor 5 rotates, and steel ball 12 extrudes
Retainer ring 1301, motor shaft 501 are rotated simultaneously with retainer ring 1301, and driving gear 6 can not be driven concurrently to rotate, you can are protected
Card straddle truck in handling goods will not be moved, so as to ensure the safety of personnel.
The collar 10 is rotated with driving gear 6 and is fixed on motor shaft 501, and is rotated coaxially with motor shaft 501, is ensured
Influence will not be contacted with each other during rotation, avoids the damage that collides.
Retainer ring 1301 is slidably connected on sliding seat 503 through slide bar 1302, with the synchronous axial system of motor shaft 501, works as fixation
When ring 1301 is inserted into the space between driving gear 7 and the collar 10 simultaneously so that the collar 10 rotates with motor shaft 501, will not
Influence the rotation between motor shaft 501 and retainer ring 503.
Slide bar 1302 can move axially on sliding seat 503 along motor shaft 501 so that retainer ring 1301 can stretch into actively
Space between gear 7 and the collar 10.
Action bars 14 is rotatably coupled to the outside of fixed cover 13, can be around the external rotating of fixed cover 13, and and fixed cover
13 together along the axial movement of motor shaft 501, and the position of retainer ring 1301 is controlled by control operation bar 14.
The outside of action bars 14 is covered with guard box 15, will not touch action bars 14 in normal operation, can avoid in operation
The unnecessary trouble of the mobile initiation of action bars 14, the end that action bars 14 only has the second bar 1402 are exposed outside guard box 15
Portion, the second bar 1402 is promoted during operation.
Guard box 15 is provided with sealing strip 1504 in the both sides up and down of the second bar 1402, without the second bar ground can
So that chute 1502 to be sealed, prevent external impurities or water from entering inside guard box 15, trigger unnecessary damage, sealing strip
1504 are fixed on the both sides up and down of chute 1502 through spring, and when the second bar 1402 slides in chute 1502, sealing strip 1504 can
To change with the second bar 1402, chute 1502 is sealed up all the time, and there is sphenocephaly 1403 both sides of the second bar 1402, can subtract
Resistance when small sealing strip 1504 slides to the second bar 1402 in chute 1502, and be advantageous to the sealing of chute 1502.
The outside of guard box 15 is stretched out in the end of second bar 1402, and the end of the second bar 1402 can be with the first signal lamp 16 or the second
Signal lamp 17 is connected, when retainer ring 1301 does not extend into the space between driving gear 7 and the collar 10, the second bar 1402 and first
Signal lamp 16 is connected, and the first signal lamp 16 sends green glow, represents that, currently without handling goods is carried out, straddle truck progress can be operated
It is mobile；And when retainer ring 1301 stretches into the space between driving gear 7 and the collar 10, the second bar 1402 and secondary signal lamp 17
Contact, secondary signal lamp 17 send feux rouges, represent current just in handling goods, it is impossible to operate straddle truck, and operation is invalid.
When straddle truck is moved to handling point, control operation bar 14, retainer ring 1301 is set to stretch into driving gear 7 and the collar 10
Between space, the second bar 1402 contacts with secondary signal lamp 17, and secondary signal lamp 17 sends feux rouges, now, then handling goods,
Resetted after cargo handling, then by action bars 14, the second bar 1402 is contacted with the first signal lamp 16, the first signal lamp 16
Green glow is sent, reminds operating personnel to carry out the movement of straddle truck.
During using the present invention, handling personnel can voluntarily control whether straddle truck can move, and avoid operating straddle truck
The danger that human users' error triggers, even if operating personnel do not notice red light alarm, straddle truck has been grasped by mistake, but due to this
The presence of device in invention, straddle truck will not also be moved, and protect just in the safety of handling goods personnel.
The present invention compared with prior art, has the advantages that：1）Protection during handling goods is added, is avoided
Straddle truck is moved and accident occurs during handling goods；2）The device is simple to operate, practical；3）The action bars of the device
Guard box is externally provided with, avoids touching in normal operation process, and does not have the debris such as dust, water and enters driver
Cause mechanical breakdown inside structure.
