Description
The utility model relates to the electronic road-junction bar of a kind of friction transmission type, is that a kind of railway that is specially adapted to has the people to guard the guard rail door gear at road junction, belongs to railway level-crossing safety protection technique field.
The guard rail door that present railway has the people to guard the road junction has three kinds of forms, i.e. vertical hinged door (revolving door), heavy curtain door and sliding door.Wherein be in the great majority with sliding door, the type of belt drive of sliding door is divided into two kinds, and a kind of is to establish the deceleration reel on ground, blocks the door switch action by the annular wire rope pulling; Another kind is a tractor to be installed blocking afterbody, and deceleration device is packed in the car, utilize the tractor traction to finish and block the door switch action, but the tractor afterbody will drag a cable that working power is provided for it.The sliding door of these two kinds of forms all needs to bury underground the traveling rail on the highway pavement of road junction.No matter block door with the wire rope pulling, or the installation tractor drags a cable on the door blocking, structure is more complicated all, slave part is many, movable member is many, and fault rate height, maintenance difficult, backward in technique, design is lack of standardization, power consumption is big, cost of installation and use is higher, holding concurrently needs bury walking rails underground at highway pavement, has increased mounting hardness and expense.
The purpose of this utility model provide a kind of simple in structure, do not have draw wire rope or cable outward, take single phase poaer supply, power consumption is low, maintenance load is few, possesses the electronic road-junction bar of the direct operated friction transmission type of manpower simultaneously.
The purpose of this utility model is to realize like this.The electronic road-junction bar of friction transmission type is to be combined by splicing door leaf, friction transmission mechanism, guiding mechanism, location servomechanism and electric control gear.
Door leaf is to save door, middle joint door, periproct door by head to be spliced into a whole fan door body, and connecting method is to utilize positive left-hand thread screw thread and sleeve that door leaf upper chord, lower chord are connect to fix, and is welded into grid shape by straight reinforcing bar and steel hoop in advance between last lower chord.Adjustable movable rod is housed under the door leaf newel post, and adjustable movable rod adopts the screw form spiral shell below newel post, and preceding newel post connecting rod is installed directive wheel down, and back newel post connecting rod is installed trailing wheel down, and the height of wheel is by the connecting rod adjustment.The friction transmission mechanism is located at the concrete pedestal central authorities under the door leaf lower chord, and main shaft is vertical with door leaf, and bearing box, friction drive and clutch are installed on the main shaft successively, and clutch directly links to each other with the reducing motor main shaft.The concrete pedestal surface is a rectangle, and long limit is parallel with door leaf, and two bearing boxs and the reducing motor of the transmission mechanism that rubs are installed in respectively on support, and support is fixed on concrete pedestal central authorities.Friction drive wheel week is matrix semi arch friction groove, and the door leaf lower chord is carried on the back and is placed in this groove, and the lower chord cross section is the circular arc that matches with the friction groove, and the friction drive relies on friction to promote the door leaf traveling.Guiding mechanism is made up of guide housing that is located at the concrete pedestal two ends and friction groove, before under the newel post under directive wheel and the back newel post trailing wheel when the door leaf traveling, have only a side to participate in leading, two guide pulleys are respectively established on guide housing top, the door leaf upper chord is clipped between the guide pulley, the cylinder of guide housing control door leaf top square position before and after during the door leaf traveling, the door leaf lower chord is carried on the back and is placed in the friction drive friction groove, with control door leaf lower position, directive wheel under the door leaf newel post or trailing wheel play the guiding booster action, when door leaf is installed guarantee lower chord carry on the back be placed in the friction groove in, adjustable movable rod under the newel post before and after adjusting, to reach that directive wheel or trailing wheel one take turns that the drive that lands and rub is born door leaf weight jointly and another takes turns the purpose that breaks away from ground, the friction of the drive of guaranteeing to rub.The location servomechanism is combined by the fixing outstanding pivot pin in tractive magnet, location hook, snubber and door leaf newel post bottom that is installed in the guide housing, tractive magnet is installed in the guide housing, electromagnet armature connects with location hook hook tail with connecting rod, location hook hook body with finger setting on guide housing, the location hook gib head is installed snubber for can rise free end under the location hook on the guide housing.Tractive magnet outage when door leaf stops traveling, armature are fallen and are promoted the location hook gib head by connecting rod and lift, and door leaf relies on the inertia traveling, outstanding pivot pin enter location hook simultaneously compression buffer stop traveling and be positioned; Tractive magnet energising during door leaf starting traveling sucts armature and drives location hook gib head whereabouts by connecting rod, and the outstanding pivot pin of door leaf is deviate from the location, and snubber discharges storage power and plays booster action, and door leaf can start rapidly.Tractive magnet power supply and the synchronous start or stop of friction drive reducing motor power supply.Electric control gear is divided into manual control and electronic control, and manually the promptly artificial direct manipulation universal seclector of control is finished just commentaries on classics, counter-rotating and the parking action of motor; Electronic control is divided into single action control and interlock control, single action control promptly utilizes a master switch to finish starting, operation and a location of blocking door and all moves, interlock control promptly utilizes a master switch to finish two or more and blocks whole actions when using simultaneously, these two kinds of forms can be singly with or use with, the master switch of electronic control is installed in indoor and outdoors, indoor and outdoors control has equivalent function, but indoorly can start a switch, locking is carried out in outdoor control, avoid idler's malfunction.When power failure or the unlatching of special circumstances need manpower push-and-pull door leaf, to press the location hook gib head and get final product push-and-pull, slide force is no more than 10 kilograms.
The advantage of the electronic road-junction bar of friction transmission type that is combined by each part mentioned above is: features simple structure, no drag rope or cable, fault rate is low, maintenance load is few, power consumption only is existing 1/10～1/8 of the door that blocks, adopt the single phase poaer supply cost of installation and use all lower, artificial direct start or stop road-junction bar when having a power failure and breaking down.Snubber can promote the door leaf starting, can overcome northerly especially winter because of it is cold to form the friction deficiency that ice sheet causes, and starts the difficulty of bringing to door leaf.
