Abstract

The utility model relates to a setting is used for the electronic fence in road junction door of quick blocked road at railway and road crossing crossing or other great crossings. Including fence door, motor reducer and wire rope and other auxiliary equipment, the motor reducer draws the back and forth movement that wire rope realized the fence door through just reversing. The utility model discloses a arch truss formula fence door of fence door for having the triangle -shaped cross -section, the two sides of a road who answers in the fence antithetical couplet written on doors respectively lays two and walks capable rail with the parallel fence door of railway circuit, and fence door rear end bottom surface is equipped with and walks the wheel that capable rail corresponds, be equipped with a direction and walk capable rail on the highway road surface, the fence in front of the door actually the face be equipped with and walk capablely and the leading wheel with the capable rail that leads away corresponds. Truss -like fence door stability is good, reduces the vibration, makes the supporting and the protective capacities of fence door improve greatly, can adopt light -duty steel, makes fence door totality weight descend. Both sides walk to go and the same direction of leading wheel on locating the highway face is moved on walking capable rail, guaranteed that two electrically operated gate can realize out or close all the time point -blank, the relativity shift can not take place, improved closed effect.

Description

Crossing electric hurdle door

One, technical field

The utility model belongs to road safety facility, is specifically related to be arranged on the safety guide rail door of the larger crossing of railway and cross-road or other for quick closure road.

Two, background technology

Existing motor-driven door pattern is more, but fault rate is higher, need frequently keep in repair, and there is certain disadvantage.

The first, now various hurdles door guide piece used is not good, what have is only arranging the guiding facility being with roller close to roadside, particularly side is that two-door larger road junction is particularly evident, and operational shock phenomenon is serious, in same plane, larger side-play amount is there is not after two closedowns, deviation is comparatively large, and protection effect is bad.

The second, existing walking rails two ends are spacing is shock proof rubber block, shock resistance effect extreme difference, and rubber block is frequently broken, and what have has also installed automatically controlled limiting device additional, and effect is also very undesirable, and also the normal phase is in failure state to automatically controlled limiting device.

Three, the deadweight of hurdle door entirety is heavier, because the support walking wheel at two ends is apart from each other, during use door in the middle of to produce sagging obvious, have plenty of to float on rail level with the battery-driven car of walking and play stabilization, and promote the operation of monolithic door.Because motor-driven carrier is comparatively light, and door deadweight is heavier, causes poor stability, by derailing yielding during external impacts or tumble.Also cause oad huge, tractive force is also less simultaneously; In addition, the anterior unparalleled side flange of bogie wheel of existing motor-driven door and guided way, without guide function, hurdle door uses poor effect.

Three, summary of the invention

The purpose of this utility model is to provide a kind of crossing electric hurdle door, and change existing motor-driven door poor stability, guiding is not good, fault rate is high, the deficiencies such as tractive force is little, complex structure, improve closed performance, reduce the labour intensity that hurdle door frequently keeps in repair, improve the operational effect of equipment.

The technical solution adopted in the utility model is: crossing electric hurdle door comprises hurdle door, motor reducer and steel rope and other accessory device, and motor reducer realizes the back and forth movement of hurdle door by rotating haulage cable.Hurdle of the present utility model door, for having the truss-like hurdle door of triangular-section, respectively lays two hurdle door traveling rail parallel with railway track at the both sides of highway of hurdle door correspondence, and hurdle behind the door face, bottom is provided with corresponding to traveling rail wheel; Highway pavement is provided with a guiding traveling rail, and hurdle in front of the door face, bottom is provided with the traveling corresponding with the traveling rail that leads and track adjusting wheel.

Steel rope of the present utility model connects into closed ring through motor reducer output shaft and fixed pulley, by push button control motor forward and backward, drive steel rope to close operation with closed ring, drag hurdle door and carry out round straight-line motion in orbit, thus realize opening or closing of this auto door.Wider crossing is made up of the motor-driven door that both sides are relative, and railway both sides have four hurdle doors, and two auto door of every side are controlled to carry out relative motion by respective power button respectively, complete opening or closing of side, road junction.Side is also like this in addition.

Truss-like hurdle door good stability, solves the problem that hurdle door operational shock is serious, and meanwhile, triangular truss structure makes the supporting of hurdle door and protective capacities greatly improve, and can adopt light-duty steel, saves material, and hurdle door overall weight is declined.The traveling on both sides and track adjusting wheel are run being located on the same guiding traveling rail in road, ensure that two auto door can realize opening or closing all the time point-blank, relativity shift can not occur, improve sealing effect.

It is simple that the utility model has structure, and cost of manufacture is low, easy for installation, processing ease, uses effective, the features such as safety factor is high, failure rate is low.Power pack section have employed motor and pulls closed ring type steel rope to drag, as long as corresponding button during operation, employee's pressing operations dish marked, just can complete the opening and closing of hurdle door.

Fig. 3 is the cross section structure schematic diagram of the utility model hurdle door.

Five, detailed description of the invention:

Crossing electric hurdle door comprises hurdle door 5, motor reducer 1, steel rope 8 and fixed pulley 9, steel rope 8 connects into closed ring through motor shaft head, rope traction hook 4 and fixed pulley 9, hurdle door 5 is connected on steel rope closed ring, motor is stretched out by rope traction hurdle door and is regained, and hurdle door 5 has lacing wire supporting rib 6 and magnesium-trellis net 7.In termination, hurdle door 5 rear end, striker 2 is housed, spring bumper 12 is provided with at traveling rail 11 two ends, when motor-driven door orbiting need stop to left end or right-hand member terminal, striker 2 Compress Spring energy disperser 12 and stopping, guarantee that whole motor-driven door can stop in the position of regulation, can not slide down again.The traveling on both sides and track adjusting wheel 10 are run on same traveling guiding rail 14, ensure that two auto door can realize opening or closing all the time point-blank, relativity shift can not occur.Door 5 base, hurdle of the present utility model is the arch upwards arched upward, middle 4cm more raised than both sides.Two non-metal rolling track adjusting wheels 13 are set near both sides, highway one end often sidling row rail 11, non-metal rolling track adjusting wheel 13 is positioned at below the outer rim of door truss both sides, hurdle, ensure that hurdle door 5 is when normally running, even if be subject to the impact of external force, also can not de-orbit easily.When also prevent operation, arch truss reveal pendulum is serious.Hurdle door 5 cross section is oblique triangle, triangular apex to the vertical line on base at 1/3rd places on base.Such design makes hurdle pedestrian outdoors, vehicle as far as possible less by the impact of hurdle gate-width degree.Below hurdle door 5, bilateral wheel rim rail Special wheel is to wheel 3 and traveling and track adjusting wheel 10.
