Rack position is adjusted, and then realizes the structure of cutting mechanism height adjustment.
When height adjustment assembly is electric drive assembly, which can be set to servo motor, the servo
Motor is fixed on spring base 202, and the motor shaft of servo motor then pushes adjusting bracket to move down, and cutting mechanism is driven to move down,
Controlling the distance that moves down can control cutting depth in a certain fixed position, realize the control of cutting depth, when not needing
When dirty, i.e., when in a non-operative state, servo motor need to only be resetted, spring 211 directly jacks up adjusting bracket, realizes cutting
Mechanism moves up, at this point, cutting mechanism is in vacant state, convenient for carrying out to Work places.
When height adjustment assembly is purely mechanic component, structure is as shown in figure 3, at this point, the rack 1 is preferably arranged to vehicle
The structure of frame is provided on the vehicle frame and pushes away automobile-used handle 213, is equipped with wheel below vehicle frame, is convenient for hand propelled operation, using hand
Pushing-type structure alleviates the labor intensity of staff, provides necessity for constructure ground decontamination work in the elimination of nuclear facilities
Technical guarantee, be specifically provided that
The height adjustment assembly includes the ratchet 212 being mounted on handle 213, is hinged on spring base 202 and bottom end
For limiting the pull rod 204 of adjusting bracket height, one end is hinged on the connecting rod 205 on 204 top of pull rod, and one end is fixed on connecting rod 205
The other end, the other end are fixed on the wirerope 207 on ratchet 212, and are arranged on handle 213 and reset for wirerope 207
Release link 206.Ratchet 212 can be fixedly welded on handle 213 with 213 rotary motion of handle, release link 206, and end is set
Right above ratchet 212, when pushing, can limit the position of 212 gear teeth of ratchet.Under the pulling of wirerope 207, pull rod 204 is right
Adjusting bracket generates downward active force, and compressed spring drives entire cutting mechanism vertical downward movement, carries out cutting operation.
The mode that adjusting bracket is fixedly connected with bearing support 102, while height adjustment assembly are preferably arranged in the present embodiment
For the set-up mode of purely mechanic component.
