Embodiment
As shown in Figure 1, 2, 3, a kind of gantry crane, including portal frame, the portal frame include driving by first respectively
Move two hollow columns 6 of device and the cooperation of corresponding rails 1 and bridge at the hollow girder of described two upper ends of column 6
26, the corresponding rails 1 every being set up in parallel and guide direction extends along the longitudinal direction, are provided with hollow girder 26 between left and right
The bull stick 8 driven by the second drive device, the centre position of bull stick 8 is provided with baffle plate 9, set in the outer rim of bull stick 8 of the both sides of baffle plate 9
There is the screw thread that the hand of spiral is opposite, the movable block 10 coordinated with its screw thread, movable block are provided with the bull stick 8 of the both sides of baffle plate 9
It is hinged respectively on 10 and is connected to connecting rod 11, the upper end of connecting rod 11 is hinged with movable block 10, and the lower end of connecting rod 11 is each passed through girder
Be hinged after elongated hole 27 on 26 lower walls with the symmetrical otic placode 12 in the bottom plate upper surface of pallet 28 by bearing pin 13, pallet 28 relative to
Slide bar 22 is set on the two sides of column 6, put in after the slotted eye 7 that the one end of slide bar 22 is pierced on the face relative with pallet 28 of column 6
Inside column 6.
Set to be hinged in the side wall of column 6 of grooved hole 7 and be connected to inclined swingle 17, the side of swingle 17 is provided with catch
19, catch 19 is connected with the one end of swingle 17 by the first spring 18, and the side of swingle 17 is provided with backplate 25, is set in backplate 25
Push rod 16 is equipped with, the pin 20 parallel with swingle 17 is provided with push rod 16, the lower end of push rod 16 passes through second with the bottom plate of column 6
Spring 29 connects, and the upper end side of push rod 16 is provided with the part teeth 21 engaged with the gear 15 on the inside bull stick 8 of column 6.
The first driving means include the cushion block 2 of the lower end of column 6, front and rear on cushion block 2 to be provided with the rolling coordinated with guide rail 1
Wheel 5, the output shaft of the first motor 4 are connected through the first decelerator 3 with the rotating shaft of roller 5 of front side on cushion block 2.
Second drive device includes the second motor 24 and the second decelerator 23, and the output shaft of the second motor 24 is through second
It is connected after decelerator 23 with bull stick 8.
The motor 24 of first motor 4 and second is band-type brake motor.
Multiple perforates 14 are provided with the bottom plate and side plate of the pallet 28, facilitate the liquid of galvanized bath to enter pallet 28
It is interior to be contacted with galvanized part thereon.
The part of slide bar 22 between the column 6 and pallet 28 is folded upward at and slide bar 22 puts on one end of column 6 and set
It is placed on the limiting plate 30 of the both sides of slotted eye 7.Limiting plate 30 can prevent pallet 28 to be lifted rear double swerve.Column 6 and support
The part of slide bar 22 between disk 28 is folded upward at enabling to pallet 28 to protrude into inside galvanized bath.
When needing to carry out zinc-plated processing to galvanized part, galvanized part is placed on pallet 28 and starts the second motor 24, second
Motor 24 drives bull stick 8 to rotate forward by the second decelerator 23, because the spiral shell that movable block 10 is different from the hand of spiral on bull stick 8
Line coordinates, therefore movable block 10 will move to the both sides of column 6 when bull stick 8 rotates forward, the distance increasing of the upper end of two connecting rod 11
Add, pallet 28 will rise.Because gear 15 engages with the teeth 21 on push rod 16, when bull stick 8 rotates forward, on bull stick 8
Gear 15 will make it that so that push rod 16 moves downward and extrudes second spring 29 and the lever 20 on push rod 16 will be close
Swingle 17, now the teeth 21 all the time with the top on push rod 16 when rotating of gear 15 contact, prevent second spring 29 will
Push rod 16 jacks up.When pallet 28 rises, after the slide bar 22 that is entered by slotted eye 7 inside column 6 contacts with swingle 17
One end of swingle 17 towards slotted eye 7 rotates up, and first spring 18 causes swingle after slide bar 22 separates with swingle 17
17 reset, and one end of swingle 17 towards slotted eye 7 is merely able to rotate up, when can so prevent that pallet 28 is broken with connecting rod 11
Prevent pallet 28 from falling and accident occurs.
Start the first motor 4, the first motor 4 drives the roller 5 of the front side of cushion block 2 to rotate by the first decelerator 3, portal frame
Moved to the direction of galvanized bath.Stop the first motor 4 when pallet 28 is located above galvanized bath and the second motor 24 of startup causes
Second motor 24 drives the rotation of the opposite direction of bull stick 8, because the lower end of push rod 16 is anti-by the upward elastic force of second spring 29, gear 15
To will be engaged during rotation with the teeth 21 on push rod 16 and make it that push rod 16 moves upwards, until on gear 15 and push rod 16 most
The teeth 21 of lower end contact, now the lower end of push rod 16 by second spring 29 pulling force so that when gear 15 rotates forward
It can be engaged with the teeth 21 on push rod 16.
The distance of lever 20 and swingle 17 when gear 15 contacts with the teeth 21 of bottom on push rod 16 on push rod 16
Becoming big swingle 17 can be rotated down towards one end of slotted eye 7, the slide bar 22 inside column 6 can slide downward, second electricity
When the drive bull stick 8 of machine 24 rotates backward, movable block 10 will move to the direction where 8 overhead gage of bull stick 9, the upper end of two connecting rod 11
Distance reduce, pallet 28 will decline, and the left and right pool wall of galvanized bath puts in the depression that the part that slide bar 22 is folded upward at is formed
Region, until the liquid in galvanized bath did not had the galvanized part on pallet 28, galvanized part can now be carried out zinc-plated.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
