Abstract

The utility model relates to a railing used for blocking pedestrians and vehicles at the gates of institutions or crossings, which is composed of an electric reductor, a railing, a wire rope and a rope pulley. The railing is a two-section crank railing which is composed of an active rod and a passive rod through the wire rope and the rope pulley. The utility model is provided with an elevating limiter, an elastic rotary tray and a buzzer alarm, can rotate and shift to resist impact when struck, and can automatically reset after being struck. The utility model overcomes the defects of non-rigid blocking of prior catenary structures, makes up the shortages of the heavy structure, large consumption, high material consumption of rolling type railings, is spread out whe blocking pedestrians and vehicles and the upright crank is upright when pedestrians and vehicles pass.

Description

Energy-saving, light curved arm railing

The utility model relates to a kind of unit gate or road junction block pedestrian and for motor vehicle bar that blocks.

At present, block in the gate of constituent parts or road junction, and pedestrian and vehicle adopts traditional catenary suspension type continuous vulcanization or roller type to block bar for two kinds.Above-mentioned two kinds are blocked bar, expend muscle power, electric power, rolled steel dosage also very big (roller type), and influence the overall appearance at gate (road junction).

The purpose of this utility model is to develop a kind of being active in one's movements reliably, and both artistic and practical, energy-conservation, light, the crank arm type that used by the height restriction occasion block bar.

The utility model by electric reducer, block bar, steel wire rope, rope sheave and form. Being characterized in blocking bar and adopting rectangular hollow metal material to make, is the two joint shapes of cranking arm, namely initiatively bar 7, by lever 8, initiatively bar 7 is fixing and driven by the output shaft 9 of electric reducer 22 by blocking pole socket 10. Fixing with rope sheave 1 by bolt 14 by lever 8, initiatively have

support wheel

2,3,4(support wheel 3,4 to place side by side in bar 7 abdominal cavities). Steel wire rope 5 one ends are fixed on fixing point 13 places of rope sheave 1, and the other end is fixed on fixing point 11 places by support wheel 3. Steel wire rope 6 one ends are fixed on fixing point 15 places of rope sheave 1, and the other end is fixed on another fixing point 12 places by support wheel 2,4. Output shaft 9 places of electric reducer 22 are fixed with spacing switch shift fork seat 27, and what clash into that spacing switch 18 realizes blocking bar lifts and fall the location.

For making the utility model shock-resistant when the state of blocking is impacted, originally block bar and be provided with the elasticity rotating disk.Be that rotating disk 20 is installed on the base 19, there is half garden shape gap rotating disk 20 sides, and its opening position is provided with location backing pin 26.Can do horizontal bidirectional along axle 21 after being impacted and change each 90 °.For guaranteeing to automatically reset after the utility model is impacted, between the sidewall of the sidewall of electric reducer 22 and base 19, spring 23 is housed.

The utility model is provided with traffic sign 17 at the hinge place of cranking arm of driving lever 7 and passive bar 8, and is coated with fluorescent material at traffic sign 17 and driving lever 7, passive bar 8 surfaces, makes it under any circumstance can both show warning, to show safety.

The control circuit that the utility model adopts comprises motor D (electric reducer 22), starting capacitance C, two-way firing switch K3, K4, limit switch K1, K2, and buzzer F(spare 25), opening toggle switch KB(spare 24), limit switch K1, K2(are part 18) be loaded on the outer wall of electric reducer 22, buzzer 25 is loaded on base 19 places, and buzzer switch 24 is that opening toggle switch KB is connected with the location backing pin 26 at place, body rotating disk 20 gap opposites.

When the bar that blocks of the present utility model is cranked arm when upright, limit switch K1 closure, the K2 open circuit, press firing switch K3, electric reducer work, the positive hour hands of power output shaft change, driving lever 7, passive bar 8 begin to fall and trail under

wire rope

5,6 effects, the back limit switch K1 that puts in place opens a way K2 closure, automatic spacing.Otherwise, press firing switch K4, power output shaft changes counterclockwise, and driving lever 7, passive bar 8 begin to lift under

wire rope

5,6 effects, and passive bar 8 turns back, and makes to block bar and crank arm uprightly, and limit switch automatic spacing afterwards puts in place.When Vehicular impact blocks bar, block bar and drive body rotating disk 20 around axle 21 rotations, opening toggle switch KB(spare 24) connection buzzer F(spare 25) circuit, give a warning, under the effect of spring 23, automatically reset each 90 ° of the two-way rotations of body rotating disk 20 energy then.

The utility model is a mechanical transmission-type, adopts electronic control, also can manually operate when having a power failure.Its railing adopts the portable structure of cranking arm, and has significantly reduced frictional dissipation in transmission process, has also reduced driving force simultaneously apart from (center of gravity is low), has reached purpose of energy saving, the span of blocking when 5-25 rice respectively matched power be that 0.15-1KW gets final product.The utility model is provided with elasticity rotating disk and buzzer warning, can be shifted with shock resistance when being impacted, and can automatically reset behind the bump.Appearance of the present utility model promptly overcome the non-rigid shortcoming of blocking of catenary suspension type continuous vulcanization structure in the prior art, remedied the deficiency of roller type structure heaviness, power consumption, expense material again.Unfold when blocking, it is upright to crank arm during clearance.Block, let pass save time, laborsaving.Be that gate, road junction desirable energy-conservation, light, crank arm type block bar, be particularly useful for being subjected to after the unit gate is decorated the occasion of height restriction.
