Abstract
The utility model provides a cantilever trackless electric door, which comprises a trailer wagon, a cantilever girder, a door and a guide bracket, wherein the trailer wagon is positioned on the cantilever girder; the cantilever girder is fixed top the guide bracket; the guide bracket is positioned on the railway public crossing through a cement base block; one end of the door is connected with the trailer wagon, and the other end of the door passes through the center of the portal guide bracket; riding wheels and horizontal guide wheels are respectively provided under the guide bracket and at two sides of the interior wall of the guide bracket, and are connected with bottom and two sides of the door; the trailer wagon is composed of upper road wheels, lower road wheels, circumferential gears and an electric motor, wherein the upper road wheels are positioned above the cantilever girder; the lower road wheels are arranged at two sides of a reverse gear, and are under the cantilever girder; the electric motor is provided in lower part of the trailer wagon body. Compared with existing technologies, the cantilever trackless electric door is characterized by: rational design, simple structure, safe and reliable performance, convenient use, easy maintenance and adaptability to a plurality of complicated places etc, and serve as a substitute of existing electric doors for popularization, thus the utility model has a good service value and generalization value.
Description
1, technical field
The utility model relates to a kind of motor-driven door, and specifically a kind of cantilevered does not have the rail motor-driven door.
2, technical background
At railway, cross-road, for ensureing railway operation safety, crossing protection equipment generally uses motor-driven door, but the in use existing deficiency of the motor-driven door of prior art is that complex structure, service life are short, especially in the installation of Rail Highway four corners, the rail excavated pavement is installed need be applied for traffic control, long construction period has a strong impact on the normal traffic order.In addition, the road conditions quality differs, and landform is different, and existing motor-driven door also is difficult to adapt to various abominable natural environments.
3, summary of the invention
The purpose of this utility model provide a kind of simple in structure, adapt to multiple complex-terrain, Installation and Debugging, use, easy to maintenance and cheap cantilevered do not have the rail motor-driven door.
The purpose of this utility model realizes in the following manner: form fulcrum by the front and back guide frame, on fulcrum, fix a traveling cantilever, one group of coaster is closely being pressed at cantilever up and down on two running faces by one group of walking wheel, and can slide freely, this coaster is fanned or is fanned guardrail more with list by flange and is connected, and guardrail is done guiding by preceding guide frame guiding wheels and supported, under the promotion of coaster, sealing and open route play and the identical protective action of common electric hurdle door.Because door grate part in this cantilevered hurdle need not installed walking wheel, the opening and close of guardrail relies on self internal force to encorbelment fully and power is carried out, so at the bottom of the road conditions conditional request utmost point.
Concrete structure is by trailer wagon, cantilever beam, hurdle door and guiding trestle are formed, trailer wagon is arranged on the cantilever beam, cantilever beam is fixed on the top of guiding trestle, guiding trestle is arranged on the railway public transport road junction by the cement matrix, one end and the trailer wagon of hurdle door link together, another of hurdle door is disconnected to be passed in the middle of the gate-type guiding trestle, base and both sides that guiding trestle below and inwall both sides are respectively arranged with support roller and horizontal guide sheave and hurdle door join, trailer wagon is by car body, last road wheel, following road wheel, reversing gear and motor are formed, last road wheel is positioned at the top of cantilever beam, the both sides that are arranged on reversing gear about following road wheel divides are positioned at the below of cantilever beam, and electrical motor is arranged on the bottom of car body.
Advantage is: not affected by environment, and without ground construction and laying track, thereby small investment, be easy to construction and short construction period, should not think the road junction traffic.Because of its running resistance is little, consumption of power is few, energy savings.In addition, the height of front and back guiding trestle form height degree is everywhere adjusted, and can satisfy various field work conditions like this, has more alerting ability.Compare with prior art, have reasonable in design, simple in structure, can be suitable for characteristics such as multiple complicated occasion, be the substitute products of existing motor-driven door, thereby have good value for applications.

Accompanying drawing 2 is the structural representations between the hurdle door guiding trestle.
Description of reference numerals: hurdle door 1; Cement matrix 2; Guiding trestle 3; Cantilever beam 4; Right lateral travelling wheel 5; Last road wheel 6; Trailer wagon 7; Left lateral travelling wheel 8; Gear 9; Reversing gear 10; Electrical motor 11; Chain 12; Support roller 13; Horizontal guide sheave 14.
5, embodiment
With reference to Figure of description 1,2, cantilevered trackless of the present utility model hurdle door is done detailed description:
This uses later-model cantilevered railless electric hurdle door, it is by trailer wagon 7, cantilever beam 4, hurdle door 1 and guiding trestle 3 are formed, trailer wagon 7 is arranged on the cantilever beam 4, cantilever beam 4 is fixed on the top of guiding trestle 3, guiding trestle 3 is arranged on the railway public transport road junction by cement matrix 2, one end and the trailer wagon 7 of hurdle door 1 link together, another of hurdle door 1 is disconnected to be passed in the middle of gate-type guiding trestle 3, base and both sides that guiding trestle 3 belows and inwall both sides are respectively arranged with support roller 13 and horizontal guide sheave 14 and hurdle door 1 join, be provided with road wheel 6 in the trailer wagon 7, following road wheel 5,9, reversing gear 10 and electrical motor 11 are formed, last road wheel 6 is positioned at the top of cantilever beam 4, following road wheel 5, the both sides that are arranged on reversing gear 10 about 9 minutes are positioned at the below of cantilever beam 4, and electrical motor 11 is arranged on the bottom of trailer wagon 7 car bodies.
The drive mechanism of the electrical motor 11 in the trailer wagon 7, up- downgoing travelling wheel 6,5,9 and reversing gear 10 is: the minor sprocket of electrical motor 11 axial regions is connected by the hinge wheel of chain 12 with right lateral travelling wheel 5 axial regions, the gear of left and right sides road wheel 5,9 axial regions is meshed with reversing gear 10, reversing gear 10 axial regions also are provided with a sprocket wheel and link by the sprocket wheel of chain with last road wheel 6 axial regions, drive trailer wagon 7 parallel motion on cantilever beam 4.
Cantilevered railless electric of the present utility model hurdle its processing and fabricating of door is very simple and convenient, and shown in Figure of description, the weldering of sheet metal anchor and the processing of canopy opening processing process of pressing general electric hurdle door get final product.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
