Description
Technical field
The utility model relates to a kind of mechanically driven kick-up block, and this car lug is used for the parking lot, and controls such as backstop and clearance are carried out in places such as expressway tol lcollection place to vehicle.
Background technology
The CN2283675Y Chinese patent discloses a typical example of mechanically driven kick-up block of the prior art.As shown in Figure 1, in this car lug, motor 1 drives pin 3 by belt 2 and speed change gear 4 and rotates in vertical plane.Like this,, move between horizontal level that pin 3 can be in vertical plane and the vertical position, block the path of vehicle at horizontal level, at vertical position clearance vehicle along with the running of motor.
Obviously, the car lug of this prior art is owing to adopting belt transmission to take very large space, and this makes that whole device is huge and heavy.
Another kind of machine driving car lug adopts the worm and gear transmission.The open DE4020075A of Deutsche Bundespatent is a typical example of this car lug.Fig. 2 shows a width of cloth diagrammatic top view of this patent disclosure.As shown in Figure 2, in this car lug, motor 1 is by by worm screw 5 ' and worm gear 6 ' and another worm screw (not shown) and worm gear 6 " the two-stage worm gearing that constitutes and drive pins 3 by axle 7 and in vertical plane, rotate, keep off a car and let pass function thereby finish.
This car lug is compared with the belt driven type car lug, has compact conformation, advantage that volume is little.But these two kinds of car lugs all have following shortcoming.At first, make pin move to vertical position from horizontal level, move to horizontal level from vertical position again, motor must rotate on both direction, but this not only needs the motor of bidirectional movement, and obviously can shorten application life of motor, the application life of mechanical part also can be owing to position out of the ordinary long term wear shortens; Another shortcoming is, the motion of pin is buffering not, and this also can make the lost of life of corresponding mechanical part and pin, particularly just in case might damage vehicle or staff when having personnel or vehicle to appear on the stroke of pin.
Summary of the invention
The utility model will overcome above-mentioned defective exactly, the little machine driving type car lug of injury that a kind of simple in structure, long service life is provided, may occurs personnel and vehicle.
Machine driving type car lug of the present utility model comprises a motor, at least one-level worm gearing, one cover crank endplay device, one pin main shaft, one buffer, one pin, shake on the other hand a linkage and a noncontacting proximity sensor or near switch, the worm screw of described worm gearing is fixedlyed connected with motor shaft, thereby rotate with motor shaft, one end of the crank of described crank and rocker mechanism is fixed on the described worm-wheel shaft, the other end is fixed in an end of the connecting rod of described crank and rocker mechanism, the other end of this connecting rod is fixed in an end of the rocking bar of described crank and rocker mechanism, the other end of this rocking bar connects a snubber, and the mid point of rocking bar is fixed in main shaft assembly.When are kept off a car in position or release position in pin arrival, noncontacting proximity sensor receives a signal respectively, and sends this signal to a control device, shuts down by this control device control motor.Manual rocker mechanism is by a pair of helical gear and worm engaging.Its effect is, when having a power failure or motor can be used the hand operation pin when breaking down.
Accompanying drawing is described
Below by accompanying drawing the utility model is described in more detail.
Fig. 1 is a width of cloth schematic diagram of a kind of car lug of the prior art.
Fig. 2 is the diagrammatic top view of another kind of car lug in the prior art.
Fig. 3 is the front view of mechanically driven kick-up block of the present utility model.
Concrete form of implementation
Fig. 3 illustrates a kind of favourable form of implementation of the present utility model.As shown in Figure 3, mechanically driven kick-up block of the present utility model comprises a motor 1, on the axle of this motor, connect a worm screw 5, this worm screw and a worm gear 6 engagements, one end of one crank 8 is fixed on the axis of rotation of worm gear 6, therefore, when worm gear 6 rotations, drive crank 8 together around this axis of rotation rotation, the other end of crank 8 and a connecting rod 9 are pivotally connected, and the other end of connecting rod 9 is connected with an end pivoting of a rocking bar 10, and the mid point of rocking bar 10 is fixedlyed connected with the power transmission shaft of pin, drive the rotation of this power transmission shaft, move between position and the vertical release position keeping off a car of level thereby drive pin.
In order to make pin 3 runnings steadily, reduce impact stress, reach equilibrium of forces, the other end of rocking bar 10 and a buffer are pivotally connected.This buffer can be a hydraulic cylinder-piston apparatus 11, also can be a spring 12.If adopt the form of hydraulic cylinder-piston, pressure is progressively set up, and linear relationship is the relation of straight line basically, but pressurized counterbalance effect in early stage is bad, if adopt spring, then early stage, balance was good, but the back segment linear relationship is bad, and the easy plastic strain of spring.Adopt the combination of the two in the present embodiment, can more help the line balancing that cushions like this, also more strengthened the intensity of device.
Inboard pivotally connected some place near buffer and rocking bar 10 is provided with two non-contact sensors 15 ' and 15 at the housing of car lug ", the control device that this two sensor and one is used to control the motor shutdown connects.The position that last non-contact sensor 15 ' is provided with makes it send a signal to control device when described pivotally connected point arrives peak (being in vertical release position corresponding to pin 13); control device control motor is shut down; following non-contact sensor 15 " position that is provided with makes it send a signal when above-mentioned pivotally connected point arrives minimum point (being in the position of keeping off a car of level corresponding to pin 13), and control device control motor is shut down.
In order to make car lug operation of the present utility model more steady, in a preferred embodiment of the present utility model, adopt the transmission of two-stage worm and gear.Because the set-up mode of two-stage worm and gear is known in mechanical field, so needn't give unnecessary details at this, does not also illustrate in the accompanying drawings.In fact, disclosed among the document DE4020075 that quotes in the background technology part of this manual is exactly the car lug of a kind of two-stage worm and gear transmission.
For car lug of the present utility model also can be used under situation about having a power failure, in a preferred embodiment of the present utility model, be provided with and on the other hand shake this manual rocking bar of bar (not shown) and be positioned at outside the car lug housing, fix a helical gear (one of two helical gears 14 among the figure) on its other end, by a pair of helical gear 14 to worm screw 5 transmissions.Like this, under situation about having a power failure, can operate boundary member of the present utility model with hand.
From top argumentation as can be seen, car lug of the present utility model compare with car lug of the prior art have the motor one-directional rotation, pin motion steadily, advantages such as compact conformation.
