Embodiments of the present application will be described in further detail below with reference to the attached drawings:
A first aspect of the present utility model provides a test vehicle, see fig. 1 to 6, comprising a frame 1, road wheels 2 and a posture correcting wheel set 3, the road wheels 2 being rollably mounted to the frame 1 along the upper surface of the rail, the posture correcting wheel set 3 comprising two ipsilateral wheels 31, a pair of contralateral wheels 32 and a compacting member 33. Two same-side wheels 31 are rollably mounted to the bracket 1 along the side of a rail and are arranged linearly along the traveling direction of the traveling wheels 2; one pair of side wheels 32 is rollably mounted to the bracket 1 along the side of the other rail; only two same side wheels 31 or only one opposite side wheel 32 are movable wheels, and the movable wheels are transversely and adjustably arranged on the bracket 1 in position under the side pressure action of the steel rail; the pressing member 33 is provided between the movable wheel and the bracket 1 so that the movable wheel is pressed against the side face of the corresponding rail, that is, the movable wheel is restrained to the two rails in the lateral direction (a line perpendicular to the extending direction of the rails between the two rails).
When the travelling wheel 2 walks along the upper surface of the steel rail, the two same side wheels 31 roll along the side surface of one steel rail, one opposite side wheel 32 rolls along the side surface of the other steel rail, all the same side wheels 31 or one opposite side wheel 32 are movable wheels, the side surfaces of the steel rail are applied to the same side wheels 31 and the opposite side wheels 32 under the action of the pressing members 33, the same side wheels 31 and the opposite side wheels 32 are limited on the two steel rails in the transverse direction (perpendicular to the extending direction of the steel rail) under the action of the pressure, in the limiting mode, the two same side wheels 31 and the opposite side wheels 32 can be always pressed on the side surfaces of the steel rail along with the travelling wheel 2 walking along the upper surface of the steel rail, no gap exists between the two same side wheels 31 and the side surfaces of the steel rail, the detection accuracy is prevented from being influenced by the deflection of the inspection vehicle in the plane (the surface of the upper end surfaces of the two steel rails) when gaps exist, and the accuracy of the detection result is ensured.
The running wheels (all the same-side wheels 31 or one pair of side wheels 32) are installed in a floating manner, so that the track gauge change of the steel rail can be adapted, the running wheels are suitable for running along steel rails with various track gauges, and the adjustment is continuous.
With the track gauge change and the rail extending direction change (turning), the distance from the opposite side wheel 32 to the two same side wheels 31 can be changed in a follow-up way, and the occurrence of clamping is completely avoided.
The bisector of the line connecting the two most distant of the two homolateral wheels 31 passes through one pair of contralateral wheels 32. Under the arrangement, the detection vehicle has a symmetrical structure in the traveling direction, and can stably travel.
With continued reference to fig. 1 and 2, two ipsilateral wheels 31 are shown, the two ipsilateral wheels 31 and one contralateral wheel 32 are arranged in an isosceles triangle, the two ipsilateral wheels 31 are positioned at two base corners of the isosceles triangle, and the contralateral wheels 32 are positioned at the vertex corners of the isosceles triangle, in this way, the posture of the whole detection vehicle can be corrected, so that the support 1 can always maintain a stable posture under the conditions of different gauges and different rail extension directions (rail turning): the direction of the perpendicular bisector of the connecting line from the opposite side wheel 32 to the two same side wheels 31 is the transverse direction of the steel rail (perpendicular to the extending direction of the steel rail), so that the stable posture can be quickly self-regulated according to different track gauges and different extending directions of the steel rail when the vehicle walks along the steel rail.
Meanwhile, as the travelling wheels 2 roll along the upper surface of the steel rail, the detection vehicle is restrained on the plane of the steel rail, so that the stable posture also comprises the posture of the bracket 1 relative to the plane of the steel rail. The support 1 is shown as being parallel to the plane in which the road wheels 2 are arranged, i.e. the support 1 is parallel to the rail surface.
With continued reference to fig. 1 to 6, which show the case where only one of the pair of side wheels 32 is a movable wheel, all of the same side wheels 31 are not movable wheels, i.e., all of the same side wheels 31 are rotatable only with respect to the bracket 1 and cannot move in the lateral direction, the arrangement is such that the pair of side wheels 32 can rapidly move as the track gauge changes and the rail extension direction changes (turns), shortening the movement time from self-adaptation to stable posture, improving the sensitivity of posture correction, and further improving the accuracy of detection.
As for the above-described movable wheels, there may be adopted a configuration in which both the same-side wheels 31 and the one opposite-side wheels 32 are movable wheels. Since the above-mentioned self-adaptation to the stable posture can be achieved after the actions of the pressing member between the same side wheel 31 and the rail and the actions of the opposite side wheel 32 and the rail are completed, one action is added, and compared with the case that only one opposite side wheel 32 is a movable wheel, the setting action speed is slightly slower, but the buffering effect is better, the buffering effect is reflected in that the pressure applied to the same side wheel 31 by the same side rail and the pressure applied to the opposite side wheel 32 by the opposite side rail are more stable, that is, the impact of the pressure to the same side wheel 31, the opposite side wheel 32 and the pressing member 33 is smaller, and the service life of the kinematic pair (the motion mode of the movable wheel relative to the bracket 1 in the transverse direction) of the relative motion part is greatly improved.
With continued reference to fig. 4, 5 and 6, the pressing member 33 has a structure including a carriage 331 and a first elastic member 332, in which the movable wheel is rotatably mounted on the carriage 331, and the carriage 331 is mounted on the bracket 1 in a laterally adjustable manner (this adjustment may be a sliding continuous adjustment or a distance adjustment through a positioning hole and a positioning column); the first elastic member 332 is installed between the bracket 1 and the carriage 331, and the first elastic member 332 provides a tensile force (not shown) or a compressive force (as shown) so that the movable wheel is pressed against the side of the rail. The first elastic piece 332 is adopted to press the movable wheel on the corresponding side surface of the steel rail, so that the structure is simple, the action is rapid, and the time required for correcting the posture is further shortened.
In addition, the first elastic member 332 provides a pulling force or a pressing force. The type of the first elastic member 332 may be flexibly selected according to practical situations, and specifically, when the first elastic member 332 is a spring, a tension spring or a compression spring may be used.
It should be noted that, the pressing member 33 further includes a sliding operation handle 452333 located outside the bracket 1, and the bracket 1 is formed with a sliding avoidance groove 111 extending in a lateral direction, and the operation carriage 331 of the sliding operation handle 452333 is slidably mounted along the sliding avoidance groove 111 by a user, so that a mounting space is formed between the movable wheel and a side surface (inner side surface or outer side surface) of the rail. The sliding position of the sliding support 1 can be conveniently adjusted by arranging a sliding operation wrench which extends out of the support 1. Meanwhile, a sliding cover plate 334 is further arranged, the sliding cover plate 334 moves synchronously with the sliding support 1, and the sliding cover plate 334 always at least partially seals the sliding avoidance groove 111 in the sliding process of the sliding support 1 so as to prevent external foreign matters from entering the protective cover 14 through the sliding avoidance groove 111 to influence the overall electrical performance.
In addition, the steel rails on the two sides are not electrically conducted through the detection vehicle. The railway traffic signal control often requires that when a train passes through, two rails are electrically conducted through the train above, and the control system gives a certain prompt such as sound and light to prompt 'the train passes through', so that the detection vehicle does not trigger the railway control system, and based on the detection vehicle, the steel rails on the two sides are not conducted through the detection vehicle, thereby meeting the requirement of the railway traffic signal control.
A further embodiment of the detection vehicle may further comprise a battery 5 fixed to the support 1, the battery 5 supplying power to the electrical equipment.
Yet another embodiment of the inspection vehicle may further include a hood 14, wherein: the protective cover 14 is fixed to the support 1 and covers the electric device and the storage battery 5. Thereby forming the protection to the electric equipment and the storage battery 5 and ensuring the normal power supply.
An embodiment of the bracket 1 comprises a cross beam 11, an on-side wheel rail 12 and an opposite-side wheel rail 13 both fixed to the cross beam 11, wherein:
the homolateral wheel longitudinal beam 12, the cross beam 11 and the lateral wheel longitudinal beam 13 are T-shaped;
the same side wheel longitudinal beam 12 is provided with at least two travelling wheels 2 along the length direction of the same side wheel longitudinal beam, and the opposite side wheel longitudinal beam 13 is provided with at least one travelling wheel 2 along the length direction of the same side wheel longitudinal beam;
The left and right sides of the same-side wheel longitudinal beam 12 are bent downwards to form two mounting portions 121, the two mounting portions 121 are kept at intervals through a support column 122 mounted in the middle to provide a space for mounting the travelling wheel 2, the two mounting portions 121 are kept at intervals through the arrangement of the support column 122, and strength and rigidity can be ensured while weight is reduced.
With continued reference to fig. 1-3, the manner in which the ipsilateral wheel 31, contralateral wheel 32 rolls along the rail side may be: two ipsilateral wheels 31 are rollably mounted to the bracket 1 along the inner side of one rail, one contralateral wheel 32 is rollably mounted to the bracket 1 along the inner side of the other rail, and a first elastic member 332 provides pressure.
The rolling mode of the same side wheel 31 and the opposite side wheel 32 along the side surface of the steel rail can be as follows: two ipsilateral wheels 31 are rollably mounted to the support 1 along the outer side of one rail, and one pair of contralateral wheels 32 are rollably mounted to the support 1 along the outer side of the other rail, a variant of which is not shown.
In order to push or pull the inspection vehicle, the embodiment of the present utility model may further include a folding assembly including an operation lever 41, and the operation lever 41 is mounted on the bracket 1 in a switchable manner (may be a rotation, a sliding or a movement of combining rotation and sliding) between a use position and a storage position.
In the use position, as shown in the figure, the operation rod 41 extends obliquely upwards and backwards from the bracket 1 to the user, so as to facilitate the hand operation of the user walking vertically, and the user can push or pull the detection vehicle by operating the extending end (extending to the end of the user) of the operation rod 41, so that the detection vehicle can move along the steel rail, and the detection vehicle can be pushed or pulled to the corresponding position of the steel rail according to actual needs.
In the storage position, this state is not shown in the drawing, the operation rod 41 extends in the lateral direction, and just the bracket 1 also extends in the lateral direction, that is, the operation rod 41 is parallel or substantially parallel to the bracket 1 and can be stored in the bracket 1, so that the operation rod 41 is stored in the bracket 1 without moving the detection vehicle (such as carrying, transporting, etc.), thereby reducing the occupied space and facilitating transportation.
Taking the rotatable movement mode of the operation lever 41 relative to the bracket 1 as an example, the connection relationship between the operation lever 41 and the bracket 1 is described, the folding assembly further comprises a first hinge seat 42, a rotating shaft 43 and a quick-mounting pin 44, and the first hinge seat 42 is fixed on the bracket 1; the first end of the operating lever 41 is hinged to the first hinge seat 42; the snap-fit pin 44 passes through the through-hole formed in the operation lever 41 and the hole formed in the rotation shaft 43 in order to lock the operation lever 41 in the use position.
Under the use position of the operating lever 41, the operating lever 41 is fixed relative to the first hinging seat 42 by means of two-point limiting of the rotating shaft 43 and the quick-mounting pin 44, namely, the operating lever 41 is fixed relative to the bracket 1, the operating lever 41 is pushed and pulled, and the travelling wheel 2 rolls along the steel rail, so that the operation of the detection vehicle can be completed. When the detection vehicle is not required to move, the quick-mounting pin 44 is pulled out, the operating rod 41 can rotate around the rotating shaft 43, and when the rotating rod rotates to a position parallel or basically parallel to the bracket 1 (the surface of the steel rail), the occupied space is minimum, and the storage and the transportation of the operation rod are facilitated.
The quick-assembling pin 44 can use an indexing pin to realize quick assembly and disassembly, thereby improving the convenience of position switching of the operating lever 41 and improving the operating efficiency.
To further facilitate user operation, the folding assembly may further include an operating member 45, the operating member 45 including:
A second hinge base 451;
Two operation handles 452 symmetrically arranged at both sides of the operation lever 41, the operation handles 452 being adjustably mounted to the second hinge base 451 between an operation position and a folding position, wherein:
In the operating position, the extending direction of the operating handle 452 forms a non-0 included angle with the extending direction of the operating rod 41, and the operating handle 452 can be conveniently held by a user to push and pull the detecting vehicle; in the closed position, the operating handle 452 is parallel (including substantially parallel) to the operating lever 41, further reducing the space occupation and improving the convenience of storage and transportation.
The operating member 45 further includes a second resilient member 454, the second hinge base 451 forming a sliding slot 4511 and a receiving limiter 4512, wherein:
The operation handle 452 is hinged in the slide groove 4511 through a hinge shaft 453, and the hinge shaft 453 is slidable along the length direction of the slide groove 4511;
In the operating position, the second elastic member 454 provides a holding force such that the operating handle 452 is perpendicular to the operating lever 41;
When the operation handle 452 needs to be folded, the user's operation (corresponding to this embodiment, the operation is to obliquely press down the free end of the operation handle 452) overcomes the holding force of the second elastic member 454, and the hinge shaft 453 slides along the length direction of the slide groove 4511 while the operation handle 452 rotates about the axis of the hinge shaft 453, so that the operation handle 452 is held at the storage stopper 4512 only by the second elastic member 454, and the operation handle 452 does not come out from the storage stopper 4512 when no external force acts.
The embodiment of the utility model can also comprise: the clamping piece 47 is configured to clamp or release the intelligent mobile terminal 6 (such as a mobile phone, a tablet computer, etc.), and various clamps can be adopted, such as a mobile phone bracket 1, a tablet computer bracket 1, etc., and specific structures thereof are not listed one by one; the folding bar set 46 has a first end hinged to the operation bar 41 and a second end hinged to the holding member 47. By adjusting the folding degree of the folding rod set 46, the gesture (height and orientation) of the clamping piece 47 is adjusted, so that the orientation of the intelligent mobile terminal 6 above the clamping piece 47 can be flexibly adjusted according to the needs of a user, and the user can conveniently watch the intelligent mobile terminal 6 at a proper visual angle. The folding bar set 46 may include a first bar member 461 and a second bar member 462 connected in sequence by a damping hinge 463.
A bracket 48 is fixed to a side surface of the holder 1 to receive the operation lever 41 in the storage position. In particular, the upper portion of the bracket 48 is formed with a receiving groove 481 to receive and swing the operation lever 41 to this position.
The second aspect of the embodiment of the utility model discloses a steel rail detector, with continued reference to fig. 1 to 6 and simultaneous reference to fig. 7 to 14, for detecting geometric parameters of a steel rail, comprising:
Any one of the above-described inspection vehicles;
The rail geometric parameter detection assembly is mounted on the bracket 1 and is configured to detect the geometric parameters of the rail.
The geometric parameters of the steel rail are detected by adopting the detection vehicle, and the structure and the beneficial effects of the detection vehicle are provided, and the description is not repeated. The method is used for detecting the geometric parameters of the steel rail, and the detection is accurate and reliable.
The gauge detecting unit is a visual detecting element. The visual detection element can be a scale value marked on the bracket 1, and the difference between the scale values corresponding to the inner sides of the two steel rails is the track gauge of the steel rails. The visual detection element can also be a ruler with scales, the ruler is fixed on the bracket 1 and is transversely arranged, and likewise, the difference between scale values corresponding to the inner sides of two steel rails is the track gauge of the steel rails.
Because the above-mentioned detection to the gauge all needs the user to observe the scale with naked eyes, calculate the difference, actual detection reliability is low, detection precision is poor, based on this consideration, the inventor makes the design: the rail geometry detecting assembly comprises a gauge detecting unit 71 (i.e. a gauge is detected by a distance sensor) configured to detect the gauges of the two rails (it is to be noted that the gauge parameters are explicitly described in TB/T3327-2010, and the description of the position and accuracy requirements is not repeated).
The gauge detecting unit 71 described above may employ a contact displacement sensor that is installed between the bracket 1 and the movable wheel and configured to detect displacement of the movable wheel with respect to the bracket 1.
In addition, the rail geometry detection assembly further includes a calculation circuit 72, the calculation circuit 72 configured to:
D=x+l 0, wherein:
