Abstract
The utility model discloses a telescopic railway crossing railing, which relates to the field of railway crossing equipment and solves the problems that the existing railway crossing straight rod railing is easy to deform due to excessive length, the operating difficulty of workers is increased, a fence-type railing cannot be used normally in the low-temperature severe weather so as to cause potential safety hazard, and the like. The telescopic railway crossing railing comprises a fixed bracket and a railing. The railing comprises one section of outer tube and at least three sections of inner tubes. The middle part of the outer tube of the railing is vertically fixedly connected with the top end of the fixed bracket. The outer end port of the inner tube sleeved on the innermost layer is provided with a pull ring. The telescopic railway crossing railing has a reasonable structure, is convenient to operate and can adopt materials such as PVC (polyvinyl chloride) or plastic steel and the like to replace metal materials such as steel and the like, so that the using amount of the steel is reduced, the requirements on low carbon and environment protection in China are met and the production cost is also reduced.
Description
Technical field
The utility model relates to a kind of level crossing equipment, particularly relates to a kind of level crossing railing.
Background technology
At present, what the level crossing railing generally used is straight-bar type, is supported by fixed mount, is operated by the road junction staff during operation.If it is longer that level crossing broad then railing just correspondingly are provided with, then exist because of the railing setting is long yielding and crooked, even because of the big frangibility of wind; Also therefore cause the railing heaviness to make the staff increase operation easier on the other hand, needing requires great effort very much could leave behind railing.What another kind of railway railing used is fence type, this railing carries out work along slideway, if run into ice and snow class weather, the fence type railing can be freezed by ice and snow or slideway is freezed by ice and snow, the situation that railing can not normally use then occurs, bring serious potential safety hazard for the pedestrian and the vehicle at passing road junction.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of telescopic level crossing railing easy to operate, rational in infrastructure to be provided.
For achieving the above object, the utility model provides a kind of telescopic level crossing railing, comprise fixed support and railing, described railing comprises a joint outer tube and is no less than the interior pipe of three joints, the middle part of described railing outer tube is vertical mode with support bracket fastened top captives joint, and the extending port internal diameter of outer tube is less than the outer tube body internal diameter; The external diameter of pipe is slightly less than the internal diameter of outer tube in first, and the other end of pipe in the projection one, the first is set is extending port and internal diameter to an end of pipe less than the internal diameter of pipe in first in first; The external diameter of pipe is slightly less than the internal diameter of pipe in first in second, and the other end of pipes in the projection two, the second is set is extending port and internal diameter to an end of pipe less than the internal diameter of pipe in second in second; The similar successively setting of pipe in other, the external port that is enclosed within the interior pipe of innermost layer is provided with a draw ring.
The cross-sectional plane of described outer tube and interior pipe is oblong.
Upper end, described outer tube middle part is provided with a reel tape type railing insulation strip, and the shell of described reel tape type railing insulation strip is captiveed joint with upper end, outer tube middle part.
The utility model beneficial effect is: use telescopic level crossing of the present utility model railing to overcome the straight-bar type railing because long and yielding, crooked even fracture and the staff operates the effort problem; Overcome also that the fence type railing meets that the low temperature inclement weather can not normally not use and the problem that has potential safety hazard; This telescopic level crossing railing can adopt materials such as PVC or plastic-steel to replace metallic materials such as iron and steel simultaneously, thereby reduces the use amount of steel, meets national low-carbon environment-friendly requirement, also reduces production costs.
Below in conjunction with accompanying drawing telescopic level crossing of the present utility model railing is described further.

Among the figure: 1, railing, pipe in 2, draw ring, 3, fixed support, 4, reel tape type railing insulation strip, 5, outer tube, 6, interior pipe, 7, first, 8, pipe in the projection one, 9, second, 10, pipe in the projection two, 11, innermost layer, 12, winding.
The specific embodiment
Embodiment is just like Fig. 1, Fig. 2, shown in Figure 3, telescopic level crossing of the present utility model railing, comprise fixed support 3 and railing 1, railing 1 comprises a joint outer tube 5 and is no less than the interior pipe 6 of three joints, the middle part of railing 1 outer tube 5 is vertical mode with the top of fixed support 3 captives joint, and the extending port internal diameter of outer tube 5 is less than outer tube 5 body internal diameters; The external diameter of pipe 7 is slightly less than the internal diameter of outer tube 5 in first, an end of pipe 7 is provided with projection 1 in first, the other end of pipe 7 is extending port and internal diameter less than the internal diameter of pipe 7 in first in first, and projection 1 and outer tube 5 are managed 7 in winning not to be drawn out outer tube 5 external less than corresponding the making of the extending port of self internal diameter.The external diameter of pipe 9 is slightly less than the internal diameter of pipe 7 in first in second, an end of pipe 9 is provided with projection 2 10 in second, the other end of pipe 9 is extending port and internal diameter less than the internal diameter of pipe 9 in second in second, and pipe 7 makes in second pipe 9 not be drawn out to manage in first that less than the extending port of self internal diameter is corresponding 7 is external in the projection 2 10 and first.Pipe 6 similar successively settings in other, the external port that is enclosed within pipe 11 in the innermost layer is provided with a draw ring 2.The cross-sectional plane of outer tube 5 and interior pipe 6 is oblong.Can hold draw ring 2 when the staff operates pipe 11 in the innermost layer of railing 1 is pulled out, then pipe 6 will be pulled out successively in other; During the end of job pipe 11 in the innermost layer of railing 1 is pushed to outer tube 5 directions, then pipe 6 will be pushed in the outer tube 5 successively in other.
As shown in Figure 4, upper end, outer tube 5 middle parts is provided with a reel tape type railing insulation strip 4, the shell of reel tape type railing insulation strip 4 is captiveed joint with upper end, outer tube 5 middle parts, the winding 12 of reel tape type railing insulation strip 4 can be pulled out when damaging or keeping in repair as railing and make interim crossing gate usefulness.
