Step alleviates the overall weight of Suo Ding mechanism.
In addition, carrying out hydraulic control by control mechanism 2, connection frame 14 is pushed and pulled, realizes the automatic throwing of I-steel 11 easily
It moves back, the personnel that do not need go to throw in person and move back, and guarantee personnel safety, improve efficiency.
Embodiment two:
As shown in Fig. 1.A kind of gate locking device, including Suo Ding mechanism 1 and control mechanism 2；The Suo Ding mechanism 1 includes work
Word steel 11, guide rod 12, spring 13, connection frame 14, pulley 15, sliding rail 16 and two sliding supports 17；11 liang of the I-steel
Side is equipped with the hole ear 18 of outwardly convex；The hole ear 18 can pass through the guiding being fixed on sliding support 17 vertically up or down
Bar 12, and its underpart is pressed on the spring 13 being threaded through on guide rod 12, and I-steel 11 is detached from basal plane；The sliding support 17
Lower part, which is equipped with, to move left and right lower sheave 15 along sliding rail 16；Described two sliding supports 17 are fixedly connected by connection frame 14；Institute
Stating control mechanism 2 moves left and right it for pushing and pulling connection frame 14.The sliding support 17 is A-frame, the guide rod 12
It overlaps with the height on the bottom edge of A-frame.16 both ends of sliding rail are equipped with limit plate 19, when limit slippage bracket 17 is mobile
It is detached from sliding rail 16；There is a hole ear 18 in every side of I-steel 11 up and down；Make I-steel 11 along the lower pressing spring of guide rod 12
It is more stable when 13；18 outwardly convex of hole ear, so that I-steel 11, when supporting gate to move down, I-steel 11 finally falls in two
Gate is supported on basal plane between a sliding rail 16；Spring 13 is compressed at this time, but is unlikely to over-voltage failure；Spring 13 makes I-shaped
Steel 11 is detached from basal plane when being not subject to gate pressure, and I-steel 11 is hanging, and own wt passes to the cunning of two sides by spring 13
Dynamic bracket 17；17 lower part of sliding support is equipped with can move left and right lower sheave 15 along sliding rail 16, can set under each sliding support 17
There are two pulley 15, so that throwing, to move back 11 frictional force of I-steel smaller；Sliding support 17 is A-frame, the guide rod 12 and three
Height on the bottom edge of angle support overlaps, and under the premise of guaranteeing stable structure, further mitigates the entirety weight of Suo Ding mechanism
Amount.
As shown in Fig. 2.The control mechanism 2 includes that the push rod 21 being fixedly connected with connection frame 14 and push rod 21 are hinged
Pull rod 22, the crankshaft 23 hinged with pull rod 22, the gear wheel 24 being fixed on crankshaft 23, the pinion gear engaged with gear wheel 24
25 and driving pinion 25 rotate control motor 26；The crankshaft 23 includes central axis 27 and crank throw 28；The central axis
27 is concentric with gear wheel 24；The pull rod 22 is hinged on the crank throw 28 of crankshaft 23.Control motor 26, which can be used, well known to be had
Line electrical connection control or wireless control, control 26 driving pinion 25 of motor drive gear wheel 24 to rotate, realize accurate angle
Rotation；The rotation band dynamic crankshaft 23 of gear wheel 24 rotates；When crank throw 28 turns to the leftmost side, push rod 21 and pull rod 22 are in same water
Horizontal line locks ingot complete state at this time to move back；When crank throw 28 turns to the rightmost side, push rod 21 and pull rod 22 are returned to same level
Line locks ingot complete state at this time to throw；When moving back lock ingot complete state and throwing lock ingot complete state, due to push rod 21 and pull rod
22 in same horizontal line, so sliding support 17 is difficult to move left and right by external disturbance, because push-pull effort crosses central axis 27, finally
It bears in the support housing of 23 two sides of crankshaft.
As shown in Fig. 3.The control mechanism 2 further includes overhead gage 3 and lower baffle plate 4；The overhead gage 3 and lower baffle plate 4
On be equipped with rotate it after the torsional spring 5 and pouring weight 6 that automatically reset, and its outside is equipped with inclined-plane 7；The crank throw 28 of the crankshaft 23
When being further continued for rotation behind rotation to leftmost side horizontal position, the torsional spring 5 on overhead gage 3 or lower baffle plate 4 will be compressed.When crank throw 28 revolves
After going to leftmost side horizontal position, in lock ingot complete state is moved back, control motor 26 carries out keeping confrontation extraneous without applied force
Interference, crank throw 28 can be stablized in the stability between overhead gage 3 and lower baffle plate 4, keeping moving back lock ingot complete state.Crank throw 28
When rotated from top to bottom to overhead gage 3 or rotated from the bottom up to lower baffle plate 4, it can be pressed on inclined-plane 7, make overhead gage 3 or lower block
Plate 4 is rotated around fixed point, the torque that crank throw 28 only needs to overcome pouring weight 6 to generate at this time can ease rotation to overhead gage 3 and lower block
Between plate 4, but when crank throw 28 will leave between overhead gage 3 and lower baffle plate 4, it is necessary to the torsion for overcoming torsional spring 5, due to push rod
21 and pull rod 22 in same horizontal line, moved left and right by sliding support 17 by external force and the rotation of crank throw 28 made to be difficult to complete,
Therefore it ensure that the stability for moving back lock ingot complete state.
As shown in Fig. 4.The invention also includes buffer gear 8, the buffer gear 8 is set to I-steel 11 and is located at the rightmost side
When lower section basal plane in；The buffer gear 8 includes shell 81, supporting part 82, guide part 83 and reset spring 84；The carrying
Guide part 83 is fixed with below portion 82, the guide part 83 is plugged together in shell 81, and 81 top edges of shell can support and hold
Load portion 82；The reset spring 84 in support bearing portion 82 is equipped in the shell 81, and shell is equipped with exhaust hole 85；It is described to hold
In the case where not by pressure, reset spring 84 keeps supporting part 82 concordant with basal plane in load portion 82.When I-steel 11 is located at the rightmost side
When, gate whereabouts is pressed in I-steel 11, and the whereabouts of I-steel 11 is pressed in supporting part 82, and supporting part 82 is since with one plane of basal plane
It sinks, final supporting part 82 is supported on 81 top edges of shell.Shell is equipped with exhaust hole 85, so that supporting part 82 sinks
In the process, have a buffering to I-steel 11, I-steel 11 finally when by gate pressure, under sink to recessed one of basal plane
Point, which prevents I-steel 11 from moving left and right, so stable that carry gate.When I-steel 11 is not by pressure
When, spring 13 makes I-steel 11 be detached from basal plane, and I-steel 11 is hanging, and supporting part 82 is extensive under the action of reset spring 84 at this time
It is multiple to arrive and basal plane same plane.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
