Efficiency.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Referring to FIG. 1, Fig. 1 is provided by the present invention for detecting a kind of tool of the detection device of vehicle body of railway vehicle outer width
The structural schematic diagram of body embodiment.
The detection device that the embodiment provides is used to detect the outer width size of vehicle body of railway vehicle.As shown in Figure 1, the detection
Device includes positioning framework and measuring part；Wherein, positioning framework has horizontal location face 1a and vertical positioning surface 1b, it is clear that
Vertical positioning surface 1b and horizontal location face 1a is perpendicular；Measuring part is installed on positioning framework, and positioned at vertical positioning surface 1b's
Opposite side, measuring part can be moved in the horizontal direction close to or far from vertical positioning surface 1b.
When practical application, the initial level distance between measuring part and vertical positioning surface 1b can be pre-set, this is first
Beginning horizontal distance is obviously greater than the outer width size of vehicle body of railway vehicle, and when to detect, vehicle body of railway vehicle can be placed at survey
It measures between component and vertical positioning surface 1b.
The car body of rail vehicle needs to detect its outer width size after welding fabrication, when detection, by the car body of welding fabrication
It is placed in positioning framework, specifically, the bottom surface of car body is contacted with horizontal location face 1a, and a side connects with vertical positioning surface 1b
Touching, to determine car body and positioning framework relative position, traverse measurement component, makes another side of itself and car body offset later,
Because the initial level distance between measuring part and vertical positioning surface 1b determines, in conjunction with the amount of moving horizontally of measuring part
The outer width size of car body is known, to judge whether the outer width size of car body meets design requirement.
By above-mentioned detection process it is found that the detection device can quickly and easily detect car body outer width size, without frequent
Carry out N Reference Alignment, and can by between measuring part and vertical positioning surface initial level distance adjustment and measuring part
Amount of movement determine the gap between car body outer width and typical set value, to facilitate subsequent car body to be adjusted.
In specific scheme, positioning framework includes pedestal 11 and two columns, for ease of description, hereafter claiming two columns
Be the first column 12 and the second column 13.
First column 12 and the second column 13 are fixedly connected in the both ends of pedestal 11, the first column 12 and the second column
13 position is corresponding, and is spaced pre-determined distance between the two, it is clear that between the first column 12 and the second column 13 it is default away from
From the outer width size for being greater than vehicle body of railway vehicle.
In a kind of specific application example, the entire length of pedestal 11 is 3927mm, the first column 12 and the second column 13
Height be 634mm, the horizontal distance between two columns is 3287mm, can satisfy the space measurement demand of bullet train.
The upper surface of pedestal 11 forms aforementioned levels positioning surface 1a, and the medial surface of the first column 12 forms aforementioned vertical positioning
Face 1b.
It should be pointed out that the side at 11 center of close pedestal that the medial surface of the first column 12 refers to here, herein will
Side close to 11 center of pedestal is referred to as interior, and the side far from 11 center of pedestal is referred to as outer, the medial surface of the first column 12
Namely first column 12 towards the side of the second column 13.
Aforementioned measuring part is installed on the second column 13, it will be understood that and measuring part is flexibly connected with the second column 13,
So that measuring part can be moved in the horizontal direction close to the first column 12 or far from the first column 12.
Specifically, the first column 12, the second column 13 can be fixedly connected with pedestal 11 by welding, simply may be used
It leans on.
In practical application, the size of the vertical positioning surface 1b of the size and the first column 12 of the horizontal location face 1a of pedestal 11
It can be set according to application demand, to ensure the reliability of positioning of car body with corresponding positioning surface.
In specific scheme, positioning framework further includes reinforcing rib 14, and reinforcing rib 14 is located at the outside of column, reinforcing rib 14
One end is fixedly connected with the top of column, and the other end is fixedly connected with pedestal 11.
In the embodiment, it is equipped with reinforcing rib 14 in the outside of the first column 12 and the second column 13, so that entire positioning
The symmetrical configuration of frame, convenient for the stability and reliability of car body when detection and positioning framework cooperation.
More specifically, reinforcing rib 14, column and pedestal 11 form triangular structure, as shown in Figure 1, the structure of triangle is more
Stablize, the setting of reinforcing rib 14 can not only improve the rigidity of positioning framework, additionally it is possible to improve the stability of positioning framework.
Reinforcing rib 14 can also be fixedly connected with column, pedestal 11 by welding.
It further include mounting blocks 21 in the embodiment, aforementioned measuring part is installed by mounting blocks 21 and the second column 13, tool
Body, mounting blocks 21 and the second column 13 are detachable affixed, and measuring part is set to mounting blocks 21, can be flexible with respect to mounting blocks 21
Movement is close to or far from vertical positioning surface 1b.That is, measuring part is detachably connected with positioning framework, in this way, examining
When surveying device not operation, measuring part can be dismantled, to be effectively protected.
In specific scheme, measuring part is specially that screw rod 22 with a scale, screw rod 22 and mounting blocks 21 are connected by screw thread
It connects, after mounting blocks 21 are fixed in the top of the second column 13, the axis of threaded mounting hole is parallel to horizontal plane, in this way, passing through
Rotary screw 22 can make screw rod 22 in the horizontal direction close to or far from the first column 12.
Specifically, screw rod 22 is equipped with reference graduation, and be configured to: mounting blocks 21 are fixed in the state of the second column 13
Under, the medial surface of the medial surface of mounting blocks 21 and the second column 13 is in same plane, that is, mounting blocks 21 medial surface with
The medial surface of second column 13 is concordant, after screw rod 22 is installed on mounting blocks 21, adjust its reference graduation make its also with mounting blocks 21
Medial surface it is concordant, and the horizontal distance between the inner face of screw rod 22 and the first column 13 be vehicle body of railway vehicle outer width mark
Quasi- value.
In this way, when detecting, the reference on the basis of the above-mentioned position of screw rod 22 is threaded in or out opposite by screw rod 22
Value can determine the practical outer width size of car body to be measured, and can determine the ruler that car body outer width corresponding standard value exceeds or is recessed
It is very little, to facilitate subsequent adjusting.
Above to provided by the present invention a kind of for detecting the detection device of vehicle body of railway vehicle outer width.It has carried out in detail
It introduces.Used herein a specific example illustrates the principle and implementation of the invention, the explanation of above embodiments
It is merely used to help understand method and its core concept of the invention.It should be pointed out that for the ordinary skill people of the art
