Lifting hole(eyelet), manhole are generally using common steel deck-plate or movable steel deck-plate capping hole.Can not automatic open close, automaticity bottom,
Have much room for improvement.
Utility model content
The utility model takes less activity space, lower swing arm there is provided a kind of open in view of the shortcomings of the prior art
Swing angle is small, and the furnace hole lower part space of occupancy is also small, and the impulsive force that cover plate is opened is also smaller, applied widely, security performance
High hanging object blind patch headstock gear.
To realize the utility model purpose, there is provided following technical scheme：A kind of hanging object blind patch headstock gear, including
Cover plate housing, be fixedly mounted on counterweight hinge on cover plate housing, the cover plate being hinged with counterweight hinge and with counterweight hinge connection
Drive device, it is characterised in that counterweight hinge include the fixed rotating shaft that fixed bottom plate, vertical direction be installed on fixed bottom plate,
It is installed on the one of fixed rotating shaft two ends, No. two bearing, the lower swing arms being fixedly connected vertical with fixed rotating shaft, consolidates with lower swing arm end
Some pieces of balancing weights connecing, the large bevel gear being socketed on fixed rotating shaft, with fixed rotating shaft installation direction be disposed vertically on turn over
Be set with three in rotating shaft, upper trip shaft, four, No. five bearings, be socketed with cone pinion, cone pinion and gamp tooth on upper trip shaft
Wheel engagement, bottom arm swing drives direction normal thereto on fixed rotating shaft rotation, upper trip shaft to be connected with returning face plate, upper upset
Plate is fixedly connected with cover plate, upper upset shaft end connection drive device.
Preferably, drive device includes reductor, the synchronizing shaft being connected with reductor and subtracting of being connected with synchronizing shaft
Speed motor.
Preferably, counterweight hinge is set at least two being installed on cover plate housing.
The utility model beneficial effect：The utility model cover plate, which is opened, takes less activity space, lower swing arm angle of oscillation
Degree is small, and the furnace hole lower part space of occupancy is also small, and the impulsive force that cover plate is opened is also smaller, and applied widely, security performance is high.

Embodiment
Embodiment 1：A kind of hanging object blind patch headstock gear, including cover plate housing 1, it is fixedly mounted on 1 liang of cover plate housing
Hold two counterweight hinges 2 being arranged symmetrically, the cover plate 3 being hinged with two counterweight hinges 2 and the driving being connected with counterweight hinge 2
Device 4, counterweight hinge 2 includes fixed rotating shaft 2.2, the installation that fixed bottom plate 2.1, vertical direction are installed on fixed bottom plate 2.1
In the two ends of fixed rotating shaft 2.2 one, No. two bearings（2.3a、2.3b）, the lower swing arm being fixedly connected vertical with fixed rotating shaft 2.2
2.5th, the lower end of lower swing arm 2.5 is fixed with some pieces of balancing weights 2.7 by screw rod 2.6（Quantity is determined according to the weight of cover plate 3）, set
The large bevel gear 2.8 that is connected on fixed rotating shaft 2.2, the upper trip shaft 2.4 being disposed vertically with the installation direction of fixed rotating shaft 2.2, on
Be set with three on trip shaft 2.4, four, No. five bearings (2.3c, 2.3d, 2.3e), be socketed with cone pinion on upper trip shaft 2.4
2.9, cone pinion 2.9 is engaged with large bevel gear 2.8, and lower swing arm 2.5, which is swung, drives fixed rotating shaft 2.2 to rotate, upper trip shaft 2.4
Upper direction normal thereto is connected with returning face plate 3.0, and upper returning face plate 3.0 is fixedly connected with cover plate 3, and the upper end of trip shaft 2.4 is
External impetus input, connects drive device 4.The synchronizing shaft that drive device 4 includes reductor 4.1, is connected with reductor 4.1
4.2 and the reducing motor 4.3 that is connected with synchronizing shaft 4.2.Reducing motor 4.3 drives synchronizing shaft 4.2 to rotate, 4.2 turns of synchronizing shaft
The dynamic upper returning face plate 3.0 for driving the driving counterweight of reductor 4.1 hinge 2 respectively is rotated, and cover plate 3 can be by flip horizontal to vertical configuration
The effect of balancing weight 2.7 on state, counterweight hinge 2 is the load for reducing the motorized motions of reducing motor 4.4.
Lower swing arm 2.5 on large bevel gear 2.8 is only needed to the certain angle of lower swing（Can be big by adjustment
Bevel gear 2.8 changes swing angle with the number of teeth of cone pinion 2.9, and the smaller space for taking furnace hole lower part of swing angle is got over
It is small）The upper returning face plate 3.0 for having engaged cone pinion 2.9 can be driven to rotate 90 degree, when the model increase of cover plate is the weight of cover plate
Amount increase, can by increase balancing weight 2.7 on lower swing arm 2.5 or increase balancing weight 2.7 and the center of rotation of lower swing arm 2.5 it
Between distance realize the driving force of upper returning face plate 3.0, open heavier cover plate；The quantity that counterweight hinge 2 can also be increased is come
Realize the cover plate for opening big specification.
