Description
Technical field
The utility model belongs to handrail tube technical field, and in particular to the reinforcement handrail tube of rail traffic vehicles.
Background technique
Rail traffic vehicles include subway, high-speed rail etc., and the speed of service of vehicle is very fast, to improve occupant's walking, standing
Vertical safety is provided with the handrail gripped for personnel to keep personnel's balance.Handrail is generally using iron pipe, stainless
Steel pipe, aluminium-alloy pipe etc. are made, and in order to make handrail tube mechanical strength with higher, improve safety, existing handrail tube is equal
It is made of the biggish metal tube of wall thickness, therefore, produces two larger drawbacks, high production cost increases car body weight.
Utility model content
Technical problem to be solved in the utility model is to provide the reinforcement handrail of rail traffic vehicles in view of the foregoing drawbacks
Pipe, structural strength is high, and non-deformability is strong, light weight, has longer service life.
The utility model solve its technical problem the technical solution adopted is as follows:
The reinforcement handrail tube of rail traffic vehicles, including tube body, the interior stiffener plate for being equipped with multiple tracks arc of the tube body,
Multiple tracks stiffener plate is uniformly distributed along the circumferential direction of tube body, and the both ends of stiffener plate are connect with inboard wall of tube body, adjacent twice reinforcing rib
The wall surface of plate is circumscribed in inboard wall of tube body.
Further, the stiffener plate is three.
Further, the stiffener plate is four.
Further, foam is filled in the space between the stiffener plate and inboard wall of tube body.
The beneficial effects of the utility model are: using the above scheme, internal arc stiffener plate interior army's tube body into
Row reinforces support, makes tube body structural strength with higher, multiple arcs stiffener plate is circumscribed, copes with the power of all directions
Effect, inside support improve pipe structure intensity, promote the wall thickness of tube body to reduce, reach loss of weight and reduction production cost mesh

Detailed description of the invention
Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will
It becomes apparent.
Fig. 1 is the cross-sectional structure schematic diagram of the utility model embodiment 1.
Fig. 2 is the cross-sectional structure schematic diagram of the utility model embodiment 2.
Fig. 3 is the cross-sectional structure schematic diagram of the utility model embodiment 3.
Wherein: 1 is tube body, and 2 be stiffener plate, and 3 be foam.
Specific embodiment
The utility model is described further with reference to the accompanying drawing.
Embodiment 1: referring to Fig.1, the reinforcement handrail tube of rail traffic vehicles, including tube body 1, tube body 1 is interior to be equipped with three arcs
Shape along the circumferential equally distributed stiffener plate 2 of tube body 1, reinforce into class 2 using metal material, the both ends of three stiffener plates 2
It is welded with 1 inner wall of tube body, adjacent two stiffener plate 2 outside wall surface close to each other is circumscribed, circumscribed place's welding or bonding, in inner wall shape
Support construction is reinforced in the inside of pairs of tube body, and the stiffener plate of arcuate structure has preferable bend resistance ability, enabling capabilities, pipe
When body stress, stiffener plate provides support in inner wall, inhibits tube body deformation, greatly improves the structural strength of tube body, promote to drop
The wall thickness of low tube body mitigates handrail tube weight, has the smaller handrail tube of wall thickness still by setting internal reinforcing structure strong
Mechanical strength, three mutually circumscribed stiffener plates are supported circular tube body in inner wall, and no matter tube body is by which side
To power effect, stiffener plate can be to providing support, booster action at this, it is ensured that the structural strength of handrail tube promotes
Handrail loss of weight, structural strength is high, and handrail tube has longer service life.
Embodiment 2: referring to Fig. 2, the reinforcement handrail tube of rail traffic vehicles, including tube body 1, tube body 1 is interior to be equipped with four arcs
Shape along the circumferential equally distributed stiffener plate 2 of tube body 1, reinforce into class 2 using metal material, the both ends of four stiffener plates 2
It is welded with 1 inner wall of tube body, adjacent two stiffener plate 2 outside wall surface close to each other is circumscribed, circumscribed place's welding or bonding, in inner wall shape
Support construction is reinforced in the inside of pairs of tube body, and the stiffener plate of arcuate structure has preferable bend resistance ability, enabling capabilities, pipe
When body stress, stiffener plate provides support in inner wall, inhibits tube body deformation, greatly improves the structural strength of tube body, promote to drop
The wall thickness of low tube body mitigates handrail tube weight, has the smaller handrail tube of wall thickness still by setting internal reinforcing structure strong
Mechanical strength, four mutually circumscribed stiffener plates are supported circular tube body in inner wall, and no matter tube body is by which side
To power effect, stiffener plate can be to providing support, booster action at this, it is ensured that the structural strength of handrail tube promotes
Handrail loss of weight, structural strength is high, and handrail tube has longer service life, fills in the space between stiffener plate and inboard wall of tube body
Foam 3, foam 3 play the role of buffering and shock-absorbing, absorb external force ability, promote the service life for extending tube body, meanwhile, it absorbs
Vibration improves comfort, the safety for holding handrail tube, avoids grasping uncomfortable caused by shaking and unexpectedly slip out of the hand, safety
It is high.
Embodiment 3: referring to Fig. 3, the reinforcement handrail tube of rail traffic vehicles, including tube body 1 sets that there are three cut in tube body 1
Face is elliptoid along the circumferential equally distributed stiffener plate 2 of tube body 1, is reinforced into class 2 using plastic material, three stiffener plates
2 it is Nian Jie with tube body with the opposite wall surface of tube body 1, adjacent two stiffener plate 2 outside wall surface close to each other is circumscribed, the welding of circumscribed place
Or bonding, it is formed in inner wall and support construction is reinforced to the inside of tube body, the stiffener plate of arcuate structure has preferable bend resistance
Ability, enabling capabilities, when tube body stress, stiffener plate provides support in inner wall, inhibits tube body deformation, greatly improves tube body
Structural strength promotes the wall thickness for reducing tube body, mitigates handrail tube weight, makes the smaller handrail of wall thickness by the way that internal reinforcing structure is arranged
Pipe still has strong mechanical strength, and three mutually circumscribed stiffener plates are supported circular tube body in inner wall no matter
Effect of the tube body by the power in which direction, stiffener plate can be to offer supports, booster action at this, it is ensured that handrail tube
Structural strength promotes handrail loss of weight, and structural strength is high, and handrail tube has longer service life.
