Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
, with Fig. 5, Fig. 6 as reference, actual installation position is by that analogy for right position in below describing.
Reference picture 1, Fig. 2, Fig. 3, Fig. 4, the structure of apparatus of the present invention is, including erection support 1 and balance boom support 8,
Erection support 1 passes through multiple fastening bolts 2 and is fixed on caliper housing 18, and level is provided with oil in erection support 1
Cylinder 15, the cylinder body of oil cylinder 15 is fixedly connected by multiple (four) bolt I13 with installing plate 12, and installing plate 12 is again by multiple
(two or four) bolt II14 is fixedly connected with erection support 1, and the piston rod end of oil cylinder 15 is fixed with guiding rail 3 and connected
Connect, the upper surface right position of guiding rail 3 is respectively equipped with inclined-plane, and left and right surface slope is identical；
Balance boom support 8 fixedly mounts (welding) on caliper rotary body 19, and the hollow position for balancing boom support 8 passes through pin
Axle II9 is hinged with equalizer bar 10, and a roller housing 5 is hinged with by a bearing pin I7 respectively at the two ends of equalizer bar 10 or so,
The two ends of equalizer bar 10 or so are also hinged with a reset latch 6 simultaneously by the bearing pin I7 per side, the half opening of roller housing 5 per side
The outer wall of reset latch 6 of the side is sleeved on, two half openings of roller housing 5 directions balance boom support 8, outside each roller housing 5
Wall is installed with a roller 4 towards the position of guiding rail 3；Two have been arranged symmetrically it again at the two ends of equalizer bar 10 altogether
Position 6, two roller housings 5 of latch and two rollers 4, and two roller housings 5 are symmetrical set, two reset latches 6 or so
It is symmetrical arranged, two rollers 4 are symmetrical set；
When some roller 4 is subject to the active force of lifting, it is ensured that roller housing 5 or lift upwards that the roller 4 is connected
Rise, or the roller housing 5 that the roller 4 is connected can only be outwards dug without using upward lifting；
The central upper portion line position of equalizer bar 10 is provided with flange, the top of equalizer bar 10 is symmetrical arranged along center line both sides
Fluted, i.e., flange both sides are respectively arranged with a groove, and the top of balance boom support 8 is provided with damping bolt 11, damping
Spring 16 and damper rod 17 are installed in the endoporus of bolt 11.
During initial position damper rod 17 downwards with the upper flange apical grafting of equalizer bar 10, now two reset latches 6 do not have
Put in pin-and-hole；During work, the stress of equalizer bar 10 is swung, and the reset latch 6 of wherein side is put in pin-and-hole to lower swing, is damped
Bar 15 is in the presence of the thrust of spring 16 in the groove of jacking opposite side, it is ensured that the operating position hold mode of equalizer bar 10 can
By property.
Be provided with supporting surface on the front end cantilever of erection support 1, for guide and support guide guide rail 3 smoothly advance or
Retreat, realize the slide anteroposterior of guiding rail 3, it is to avoid the piston rod when roller 4 rolls guiding rail 3 to oil cylinder 15 brings
Radial forces.
Oil cylinder 15 can also be replaced with cylinder.
The course of work of apparatus of the present invention is,
During work, balance boom support 8 and its all parts are common as caliper rotary body 19 is under the drive of breach gear wheel 20
With the rotation for carrying out relative to caliper housing 18 suitable/reverse direction；When the position of switch back latch 6 is needed, oil cylinder 15 is promoted
Guiding rail 3 projects forwardly to correct position towards balance boom support 8；Balance boom support 8 on caliper housing 18 is suitable/reverse direction rotation
Turn, and guiding rail 3 is not rotated；
Reference picture 5, (be i.e. balance boom support 8 to move from left to right, leads when caliper rotary body 19 turns clockwise in Fig. 5
Direction guiding rail 3 is relatively motionless), along inclined-plane lifting after the roller 4 on the right side of equalizer bar 10 and the contact of incline plane in the left side of guiding rail 3, by
Can not outwards be dug in the roller housing 5 for being connected, the connected upward lifting of roller housing 5 can only be driven to drive the right side of equalizer bar 10
It is swung up around bearing pin II9, then the left side of equalizer bar 10 is to lower swing, and the reset latch 6 for being hinged the left side of equalizer bar 10 is downward
In moving and corresponding to the pin-and-hole of insertion breach gear wheel 20；While the jacking equalizer bar in the presence of the thrust of spring 16 of damper rod 15
In the groove of 10 upper rights, reliable safety effect is played；
Reference picture 6, caliper rotary body 19 continues to turn clockwise, when roller 4 and the guiding rail 3 in the left side of equalizer bar 10
During the contact of incline plane of left side, because roller housing 5 is half round cut tube-in-tube structure, can outwards dig, it is oblique in the left side of guiding rail 3
Face is pushed under effect, and left side roller 4 drives the bearing pin I7 of the roller housing 5 around place of the side to swing out, such equalizer bar
The upper-lower position of reset latch 6 in 10 left sides and left side is motionless, and damper rod 15 is located at equalizer bar 10 in the presence of the thrust of spring 16
It is also motionless in the groove of upper right；The reset latch 6 for avoiding the left side that will be already inserted into pin-and-hole is extracted, it is ensured that replaced
Latch state reliability in journey.
Conversely, during caliper 19 rotate counterclockwise of rotary body, 10 left side roller of equalizer bar 4 drives and moved on the roller housing 5 of the side,
The left side of equalizer bar 10 is swung up, and the right side of equalizer bar 10 is moved down to the reset latch 6 on the right side of lower swing drive and correspondence is inserted
In entering the pin-and-hole of breach gear wheel 20, while the upper left-hand of jacking equalizer bar 10 in the presence of the thrust of spring 16 of damper rod 15
In groove；Caliper rotary body 19 continues rotate counterclockwise, and 10 right roller of equalizer bar 4 drives the roller housing 5 of the side around oneself
Bearing pin I 7 swing out, it is ensured that the upper-lower position of reset latch 6 on right side is motionless, while damper rod 15 is in the thrust of spring 16
Effect is lower in the groove of the upper left-hand of equalizer bar 10, realizes the reliability of transposition.
