Specific embodiment
Referring to the drawings, the utility model is described in further detail with specific embodiment.
As shown in Figures 2 and 3, the tripper that latches includes lock tongue 1, lock shield 2, lock tongue spacer pin 6, lock tongue axis 7, activity song Bar 9, fixed link 10 and limit plate 8, lock tongue spacer pin 6 are connect with the doorframe of operating platform 4, the door of lock tongue axis 7 and operating platform 4 Frame connection, lock shield 2, which is mounted on the doorframe of operating platform 4, covers lock tongue 1, lock tongue spacer pin 6, the tail portion of lock tongue 1 and lock Tongue axis 7 rotationally connects;There are three limit plates 8, and three limit plates 8 are mounted on aircraft bowser hoistable platform, movable curved bar 9 Across three limit plates 8;The lower end of movable curved bar 9 can be contacted with fixed link 10, can also be separated with fixed link 10;It is movable bent When the upper end of bar 9 moves upwards, can withstand on lock tongue 1 makes lock tongue 1 turn an angle on the basis of lock tongue axis 7.It is movable bent Bar 9 includes lock tongue top plate 11, long round steel 12, square tube 13, short round steel 14, and lock tongue top plate 11 and the upper end of long round steel 12 are welded on Together, square tube 13 and the lower end of long round steel 12 weld together, and short round steel 14 welds together with square tube 13;Lock tongue top plate 11, Long round steel 12, square tube 13, short round steel 14 constitute Z-type bending staff design, prevent left-right rotation, flat in operation by three limit plates 8 Left and right is carried out to movable curved bar 9 on platform doorframe, swing limits.Long round steel 12 passes through (the two limits of both the above limit plate 8 In the plate of position, above one close to lock tongue top plate 11, below one close to square tube 13), short round steel 14 passes through third limit plate 8.
Fixed link 10 is fixedly installed on the hoistable platform chassis 5 of aircraft bowser hoistable platform, does not rise with platform.
Lock shield 2 is fixedly installed in aircraft bowser hoistable platform on the doorframe of operating platform 4, three limit plates 8 In the upper surface of two be fixedly mounted on doorframe, below one be mounted on the bottom plate of operating platform 4.
Movable curved bar 9 can move up and down under the action of gravity and fixed link 10 with respect to operating platform 4, and then control lock The position of tongue 1, to realize automatic locking and the unlock of part operating platform door 3.
Lock tongue 1 is made by square tube, and intensity is good, to operating platform door 3 carry out locking, lock shield 2 by steel plate bending and At main function is protection.
The main function of lock tongue spacer pin 6 is the rotational angle for limiting lock tongue 1, and lock tongue axis 7 is the center of rotation of lock tongue 1 Axis.
As shown in Fig. 1,2 and 8, when aircraft bowser hoistable platform is under original state, operating platform 4 is in situ When, in contact condition, fixed link 10 is withstood upwards for the lower end surface of short round steel 14 and the upper end surface of fixed link 10 in movable curved bar 9 Movable curved bar 9, lock tongue top plate 11 withstand lock tongue 1 upwards, and lock tongue 1 is in a high position, at this point, operating platform door 3 is in the unlocked state, It can open.
As shown in Fig. 4,5,6 and 9, when operating platform 4 rises, the lower end surface of short round steel 14 and 10 upper surface of fixed link by It is gradually detached from, movable curved bar 9 is under gravity with respect to 4 slide downward of operating platform, while lock tongue 1 is also under the effect of gravity (counter clockwise direction in Fig. 2) slowly is rotated to 3 direction of part, when lock tongue top plate 11 is moved downwardly to uppermost limit plate 8 When setting, be blocked to move still further below, and for lock tongue 1 just at horizontality shown in fig. 6, operating platform door 3 can not at this time It opens, realizes automatic locking.
When operating platform 4 declines, when by dropping down onto situ, the lower end surface of short round steel 14 and fixed link 10 in movable curved bar 9 After the face contact of upper end, continue decline then movable curved bar 9 opposite 4 upward sliding of operating platform under the action of fixed link 10, simultaneously The free end of lock tongue 1 is rotated up (in Fig. 6 clockwise), when operating platform 4 drops down onto original position under the promotion of movable curved bar 9 When, lock tongue 1, in a high position, at this point, operating platform door 3 is in the unlocked state, can be opened under the effect of movable curved bar 9.Three Second in limit plate 8 can block square tube 13, the stroke of limitation activity curved bar 9.
Lock tongue 1 is rotated upwardly into certain angle clockwise, can be blocked by lock tongue spacer pin 6.
It should be noted that movable curved bar 9 can be replaced with the motion bar of the other shapes such as straight motion bar.
The above is not intended to limit the utility model, only to the preferred embodiment of utility model for ability For the technical staff in domain, various modifications and changes may be made to the present invention.
