Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
Fig. 1 and 4 to 6 schematically show a bellows positioning device according to an embodiment of the present invention. As shown in fig. 1, the bellows positioning apparatus includes a first support mechanism 20 and a gauge 30 for indicating a preset coordinate B in a horizontal direction; the gauge 30 is arranged to be rotatable about its point of attachment to the first support mechanism 20 and to be lockable in a preset position relative to the first support mechanism 20; when the measuring instrument 30 rotates to a preset position, an included angle Q is formed between the distribution direction of the scale marks on the measuring instrument 30 and the first supporting mechanism 20, so that the measuring instrument 30 and the first supporting mechanism 20 are attached to the outer wall of the box girder.
When the corrugated pipe positioning device is used, firstly, design parameters are obtained according to the design standard of the corrugated pipe position, the design parameters comprise corrugated pipe bottom coordinates A and box girder inclination angles M, and then the box girder inclination angles M in the design parameters are substituted into a calculation formula of the included angle between the distribution direction of scale marks and the first supporting mechanism 20: 180-M=Q, and calculating to obtain an included angle Q between the first supporting mechanism and the metering instrument; substituting the bottom coordinates A of the design corrugated pipe into a preset coordinate calculation formula: a/sinM =b, and calculating to obtain a preset coordinate B; then, as shown in fig. 6, the measuring instrument 30 is rotated around the connection point with the first supporting mechanism 20, so that an included angle Q is formed between the distribution direction of the scale marks on the measuring instrument 30 and the first supporting mechanism 20, at this time, the first supporting mechanism 20 is locked relative to the measuring instrument 30, then, the first supporting mechanism 20 is placed between the box girder 50 and the bottom mould 60, that is, the first supporting mechanism 20 is attached to the bottom wall of the box girder 50, and because the included angle Q is formed between the first supporting mechanism 20 and the distribution direction of the scale marks, the distribution direction of the scale marks is kept at the same inclination angle as the inclination angle M of the box girder, at this time, the measuring instrument 30 is attached to the outer side wall of the box girder 50, therefore, the size and the operation space of the bellows positioning device are not limited by the space inside the box girder 50, and the flatness of the top surface of the bottom mould 60 is better, and the measurement accuracy of the bellows positioning device can be ensured; the preset coordinate B indicated by the gauge 30 in the horizontal direction is the bottom position of the bellows 51 positioned by the bellows positioning device, so that the box girder 50 can be marked under the indication of the gauge 30, so that the installation position of the bellows 51 in the box girder 50 can be found simply and quickly.
The angle between the distribution direction of the graduation marks on the measuring instrument 30 and the first supporting mechanism 20 may be confirmed by an external angle measuring mechanism, or an angle measuring mechanism for measuring the angle between the distribution direction of the graduation marks on the measuring instrument 30 and the first supporting mechanism 20 may be provided on the bellows positioning device. The method is particularly suitable for controlling the included angle between the distribution direction of the scale marks on the measuring instrument 30 and the first supporting mechanism 20 by controlling the included angle between the measuring instrument 30 and the first supporting mechanism 20 when the included angle between the distribution direction of the scale marks and the measuring instrument 30 is constant.
In this embodiment, the bellows positioning device further includes a first angle measuring device for measuring the angle of rotation of the gauge 30 relative to the first support mechanism 20, the first angle measuring device being provided on the gauge 30. Therefore, the rotation angle of the measuring instrument 30 relative to the first supporting mechanism 20 can be measured by the first angle measuring device, so that the relative rotation precision of the measuring instrument and the first supporting mechanism 20 is ensured, the distribution direction of the scale marks and the precision of the angle of the first supporting mechanism 20 are controlled, and the operation is convenient.
In this embodiment, as shown in fig. 1 and 4, the measuring instrument 30 includes a measuring surface 31 and an indicating mechanism 40, and both the scale lines and the indicating mechanism 40 are disposed on the measuring surface 31, wherein the indicating mechanism 40 is configured to be capable of reciprocating along the direction in which the scale lines are distributed, and has a locking position, which is a position of the indicating mechanism 40 on the measuring surface 31 when the indicating mechanism 40 indicates the preset coordinate B along the horizontal direction, that is, the indicating mechanism 40 has a locking function. The distribution direction of the graduation marks is the same as the extending direction of the measuring instrument 30. Thereby, when the indicating mechanism 40 indicates the preset coordinates B in the horizontal direction, the indicating mechanism 40 can be locked to the measuring surface 31 so as to mark the installation position of the bellows 51 in the box girder 50, so that the bellows 51 can be accurately and quickly installed in the box girder 50.

Thereby controlling the included angle between the distribution direction of the scale marks and the first supporting mechanism 20 by measuring the rotation angle of the measuring instrument 30 relative to the first supporting mechanism 20.
Specifically, as shown in fig. 1, the indicating mechanism 40 includes a second supporting mechanism 42 for indicating the preset coordinates B in the horizontal direction and a first moving mechanism 41 having a limiting mechanism for driving the second supporting mechanism 42 to reciprocate in the distribution direction of the scale marks; the second support means 42 is arranged on the measuring surface 31 by means of the first displacement means 41. Therefore, the second supporting mechanism 42 can be rotated by a certain angle, so that the second supporting mechanism 42 is parallel to the first supporting mechanism 20, then the first moving mechanism 41 drives the second supporting mechanism 42 to move, and when the second supporting mechanism 42 indicates the preset coordinate B along the horizontal direction, the second supporting mechanism 42 is locked relative to the measuring surface 31 through the limiting structure, so that the box girder 50 can be marked according to the preset coordinate B indicated by the second supporting mechanism 42, and the corrugated pipe 51 is arranged at the marked position, so that the corrugated pipe 51 is positioned.
In this embodiment, as shown in fig. 1 and 3, the specific implementation manner of the first moving mechanism 41 is realized by a guide rail 411 and a slider structure, specifically, the guide rail 411 is disposed along the direction of the scale mark distribution of the measuring surface 31, and the difference in height between one end of the guide rail 411, which is close to the first supporting mechanism 20, and the first supporting mechanism 20 is less than 10cm, so as to measure the coordinates of the bellows 51. Further, since the first moving mechanism 41 also has a limit structure, a screw hole communicating the outside with the guide rail 411 may be provided on the slider, and a bolt and a nut may be connected in the screw hole, and when the slider moves in place, the slider may be fixed on the guide rail 411 by tightening the nut.
In other embodiments, the first moving mechanism 41 may also be configured in a structure that a cylinder or an oil cylinder drives a slider to reciprocate on a guide rail adapted to the slider, where the guide rail is disposed along a distribution direction of the graduation marks (not shown in the drawing).

When the metering instrument 30 is required to rotate, the damping rotating shaft 23 drives the metering instrument 30 to rotate clockwise around the supporting piece 22, and after the metering instrument 30 rotates in place, no external force is applied to the metering instrument 30 around the clockwise; at this time, the gravity of the gauge 30 acting on the support 22 is around the counterclockwise direction, the gauge 30 is locked relative to the support 22, which is equivalent to the counter-clockwise fixed limit of the gauge 30 relative to the support 22 under the action of the damping rotation shaft 23, and at this time, even if the gravity of the gauge 30 acting on the support 22 is around the counterclockwise direction, the relative rotation between the support 22 and the gauge 30 does not occur any more, so that the gauge 30 can be supported by placing the support 22 between the box girder 50 and the bottom die 60.
In other embodiments, the first rotation positioner may also be implemented by a bolt-nut structure, specifically, the support member 22 is pivotally connected to the measuring surface 31 of the measuring instrument 30, where the pivot shaft 24 is configured such that one section is a polished rod and the other section is a threaded rod, the support member 22 is sleeved on the polished rod, and the support member 22 can rotate around the axis of the polished rod, and also can move along the axis of the polished rod, the threaded rod is partially located outside the measuring instrument 30, and the threaded rod is sleeved with the nut 25.
