Detailed Description

The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.

The utility model provides a flexible interfacing apparatus of aerial rail train, including butt joint track 100, track frame 200 and elastic component 300, butt joint track 100 hangs on track frame 200 through the rope spare, avoid track frame 200 to drop, butt joint track 100 is connected with track frame 200 through elastic component 300 simultaneously, avoid butt joint track 100 to rock, elastic component 300 plays limiting displacement to butt joint track 100, specifically, the one end and the track frame 200 of elastic component 300 are connected, the other end and the butt joint track 100 of elastic component 300 extensible component are connected, the quantity of elastic component 300 is at least three, two in these at least three elastic component 300 arrange in one side of butt joint track 100, another in these at least three elastic component 300 arranges in the opposite side of butt joint track 100. That is, both sides of the docking rail 100 are connected to the rail holder 200 through the elastic member 300, so that the shaking of the docking rail 100 in a certain direction or directions can be limited, and meanwhile, a certain offset can be provided when the docking rail 100 is docked; in addition, due to the existence of the elastic member 300, in the solution disclosed in patent 2019101347515, when the docking track 100 is docked, after the concave part and the convex part are aligned, the trolley suspending the docking track 100 stops running and is locked, and at this time, the docking track 100 is lowered, and due to the existence of the elastic member 300, the docking track 100 itself has a certain movement amount relative to the trolley, so that the docking track 100 moves under the action of gravity and an inclined plane until precise docking is completed, and the trolley does not need to move, thereby having a small overall weight and a small inertia, and simultaneously, due to the buffer action of the elastic member 300, the lowering speed is not fast, and the inertial impact caused by the slow lowering is further reduced.

Specifically, the arrangement of the elastic member 300 may mainly include (but is not limited to) the following:

as shown in fig. 3 and 4, two elastic members 300 are disposed on one side of the docking rail 100, one elastic member 300 is disposed on the other side, and the elastic member 300 on the other side is disposed at the middle portion of the two elastic members 300 on the one side, which is equivalent to that the two elastic members 300 on the one side are symmetrically distributed with respect to the elastic member 300 on the other side, so that, when the resultant force of other external forces is zero, only the acting force of the elastic members 300 can more easily ensure that the resultant force of the acting forces of the elastic members 300 on the docking rail 100 is zero, and the docking rail 100 can be moved more smoothly;

the extension and contraction directions of the elastic members 300 may be perpendicular to the extension line of the docking rail 100, that is, the direction B in fig. 3 to 7, that is, parallel to the lateral direction of the docking rail 100, that is, the direction a in fig. 3 to 7, as in fig. 3, all the extension and contraction directions of the elastic members 300 are perpendicular to the extension line of the docking rail 100, of course, the extension and contraction directions of the elastic members 300 may also be arranged in a manner inclined with respect to the extension line of the docking rail 100, as in fig. 4, two elastic members 300 arranged at one side of the docking rail 100 (the two elastic members 300 at the left side in fig. 4) are arranged in a manner inclined with respect to the extension line of the docking rail 100, whether inclined with respect to the extension line of the docking rail 100 or arranged perpendicular to the extension line of the docking rail 100, as long as in the case where the resultant force of other external forces is zero, only the resultant force of the elastic members 300 acts on the docking rail 100 and then the docking rail 100 is finally stationary, that is, the resultant force of the plurality of elastic members 300 to the docking rail 100 is zero;

as shown in fig. 5 and 6, two elastic members 300 are respectively disposed at two sides of the docking track 100, four elastic members are symmetrically disposed with respect to the center of the docking track 100 in pairs, the extending direction of the elastic member 300 in fig. 5 is perpendicular to the extending line of the docking track 100, and the scheme in fig. 6 is that two elastic members 300 disposed at the same side of the docking track 100 are disposed in a splayed shape and symmetrically disposed with respect to the middle of the docking track 100, so that the swing amplitude of the docking track 100 in the direction of a can be limited, and the swing amplitude of the docking track 100 in the direction of B can be limited; it can also be arranged as in fig. 7, combining the two methods of fig. 5 and fig. 6, and there are four elastic members 300 arranged on each side of the docking track 100, of course, the number and arrangement of the elastic members 300 can be other.

According to the above arrangement, the elastic members 300 are disposed on the two sides of the docking rail 100, so that the shaking of the docking rail 100 can be limited within a preset range, and meanwhile, when the docking rail 100 is docked with other rails, the docking rail 100 can move within a certain range, if the docking rail 100 is accurately positioned with other rails by means of slope matching as shown in fig. 1, the docking rail 100 can have a certain moving range relative to the rail frame 200, and the docking rail 100 can move, which is more convenient and energy-saving than the moving rail frame 200.

The scheme still has other disadvantages, if the butt joint rail 100 is not aligned with other rails in the transverse direction and the longitudinal direction (generally difficult to align) in the moving process of the rail frame 200, when the butt joint rail 100 moves downwards to complete butt joint with other rails, the butt joint rail 100 can move relative to the rail frame 200 until accurate butt joint is completed, acting forces given to the butt joint rail 100 by the elastic members 300 on the two sides of the butt joint rail 100 are different, the resultant force is not zero, the butt joint rail 100 tends to move in a certain direction, mounting stress exists between the butt joint rail 100 and the rail frame 200, and potential safety hazards exist in the subsequent use process.

In order to improve to solve the above problems, a preferable scheme may be adopted:

the first scheme is as follows: adjusting the deformation of all the elastic members 300, so that the deformation of the abutted elastic members 300 is the same as the deformation of each elastic member 300 before the abutting of the abutting rails 100 is started, specifically, referring to fig. 6, one end of each elastic member 300 is connected to the rail frame 200 through an automatic telescopic member 400 such as a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, if the deformation of each elastic member 300 before the abutting of the abutting rails 100 is completed is L, and the abutting rails 100 are wholly deviated to the left by Δ X after the abutting is completed, the deformation L- Δ X of the two elastic members 300 on the left side and the deformation L + Δ X of the two elastic members 300 on the right side are set, and in order to make the resultant force applied to the elastic members 300 of the abutting rails 100 after the abutting is completed zero, the two automatic telescopic members 400 on the left side are shortened by Δ X, so that the deformation of the two elastic members 300 on the left side is restored to L, and the two automatic telescopic members 400 on the right side are extended by Δ X, so that the deformation amount of the two elastic members 300 on the right side is restored to L;

scheme II: adjusting the deformation amount of all the elastic members 300 to make the resultant force of all the elastic members 300 received after the butt joint of the butt joint rail 100 be zero, but different from the first solution, specifically, still referring to fig. 6, one end of the elastic member 300 is connected to the rail frame 200 through an automatic telescopic member 400 such as a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, if the deformation amount of each elastic member 300 before the butt joint of the butt joint rail 100 is completed is L, and the butt joint rail 100 is integrally shifted to the left by Δ X after the butt joint is completed, the deformation amount of the two elastic members 300 on the left side is L- Δ X, the deformation amount of the two elastic members 300 on the right side is L + Δ X, in order to make the resultant force of the elastic members 300 received after the butt joint rail 100 is zero, the deformation amount of the two automatic telescopic members 400 on the left side is shortened by Δ L, the deformation amount of the two elastic members 300 on the left side is both changed to L- Δ X + Δ L, and the deformation amount of the two elastic members 300 on the right side is changed to L- Δ X + Δ L, the right side of automatic telescoping piece 400 is required to extend 2 deltax-deltal;

the third scheme is as follows: all the elastic members 300 are connected with automatic telescopic members 400, the deformation amount of some of the telescopic elastic members 300 is adjusted, so that the resultant force of all the elastic members 300 received after the butt joint of the butt joint rails 100 is zero, specifically, still referring to fig. 6, one end of the elastic member 300 is connected with the rail frame 200 through the automatic telescopic members 400 such as a hydraulic cylinder, a pneumatic cylinder or an electric cylinder, if the deformation amount of each elastic member 300 is L before the butt joint of the butt joint rails 100 is completed, and the butt joint rails 100 are integrally shifted to the left by Δ X after the butt joint is completed, the deformation amount of the two elastic members 300 on the left side is L- Δ X, the deformation amount of the two elastic members 300 on the right side is L + Δ X, in order to make the resultant force given by the elastic members 300 received after the butt joint of the butt joint rails 100 be zero, at least two methods may be adopted, one of which is that the deformation amount of the two left side elastic members 400 is shortened by 2 Δ X is L + Δ X, at this time, the deformation amount of the two right-side expansion pieces is also L + Δ X, the resultant force of the elastic pieces 300 received by the docking track 100 is zero, and secondly, the deformation amount of the two right-side elastic pieces 300 becomes L- Δ X when the right-side automatic expansion piece 400 extends by 2 Δ X, which is the same as the deformation amount of the two left-side expansion pieces, and at this time, the resultant force of the elastic pieces 300 received by the docking track 100 is also zero;

and the scheme is as follows: the automatic telescopic parts 400 are connected to all the elastic parts 300, if the elastic parts 300 are symmetrically distributed with respect to the docking rail 100, the automatic telescopic parts 400 may be arranged only on one side, see fig. 7, the two elastic parts 300 on the left and the two elastic parts 300 on the right are symmetrically distributed with respect to the docking rail 100, the two elastic parts 300 on the upper side and the two elastic parts 300 on the lower side are symmetrically distributed with respect to the docking rail 100, in order to balance the engaging force of the elastic parts 300 caused by the movement of the docking rail 100 in the direction a not to be zero, the automatic telescopic parts 400 may be arranged on the two elastic parts 300 on the left side, the automatic telescopic parts 400 may not be arranged on the two elastic parts 300 on the right side, if the deformation amount of each elastic part 300 is L before the docking of the docking rail 100 is completed, and the entire docking rail 100 is deviated by Δ X to the left after the docking is completed, the deformation amount L- Δ X of the two elastic parts 300 on the left side, the deformation amount of the two right-hand elastic members 300 is L + Δ X, and in order to make the resultant force given by the elastic members 300 to the butted joint rails 100 zero, the two automatic telescopic members 400 on the left side can be shortened by 2 ax, the deformation amount of the two telescopic members on the left side becomes L + ax, at this time, the deformation amount of the two right telescopic members is also L + Δ X, the resultant force of the elastic members 300 received by the butt-joint rail 100 is zero, figure 7 illustrates a solution for the situation where the resultant force of the resilient member 300 caused by the movement of the docking rail 100 in the direction a is not zero, to solve the problem that the resultant force of the elastic member 300 caused by the movement of the docking track 100 in the direction B is not zero, the arrangement of the elastic member 300 shown in fig. 5 can be considered, under the guidance of basic mechanics knowledge, it is determined which elastic members 300 are configured with the arrangement of the automatic telescopic member 400, as long as the resultant force of the elastic members 300 is zero through the telescopic change of the automatic telescopic member 400 after the movement.

The deformation amount of each elastic member 300 is adjusted, and the specific adjustment amount is appropriate, so that the deformation amount of each elastic member 300 before and after the butt joint of the butt joint rail 100 can be measured, the adjustment amount can be determined by the change of the deformation amount, the displacement variation amount of each elastic member 300 before and after the butt joint of the butt joint rail 100 can be measured, the change of the deformation amount of each elastic member 300 can be calculated according to the mechanics knowledge by combining the arrangement mode of each elastic member 300, and the adjustment of the deformation amount of each elastic member 300 can also be determined by testing the force given to the butt joint rail 100 by each elastic member 300.

Specifically, displacement detection components such as infrared displacement sensors are arranged on the docking rail 100, and are used for acquiring offset of the docking rail 100 in the transverse direction and/or the longitudinal direction, that is, offset of the docking rail 100 in the a direction (transverse direction) and/or the B direction (longitudinal direction) in fig. 4 and 5, if adjustment is required so that resultant forces of the elastic members 300 received by the docking rail 100 in the longitudinal direction and the transverse direction are zero, the offset of the docking rail 100 in the transverse direction and the longitudinal direction needs to be acquired simultaneously, where the offset refers to a difference between distances between the docking rail 100 and a fixed frame before and after docking; for obtaining the amount of change in the expansion and contraction of the elastic member 300, displacement detection components such as an infrared displacement sensor may be disposed on the elastic member 300, and the amount of change in the expansion and contraction of the elastic member 300 may be obtained by obtaining the amount of deformation of the elastic member 300 before and after the butt joint of the butt joint rail 100 and then subtracting; the force sensor may be disposed on the elastic member 300 to obtain the force of the elastic member 300 before and after the butt joint of the butt joint rail 100, i.e. the amount of change in the extension of the elastic member 300 may be calculated, and of course, the adjustment manner of each elastic member 300 may also be directly calculated by the arrangement position of the force sensor in cooperation with the elastic member 300 after the butt joint of the butt joint rail 100, so that the resultant force of the elastic member 300 to the butt joint rail 100 is zero.

The above-described scheme is that the total force of the elastic members 300 received by the docking rail 100 after docking can be made zero by acquiring the amount of change in the extension and contraction of the elastic members 300 and then adjusting the elastic members 300 through the automatic extensible member 400, and in addition to this scheme, the amount of extension and contraction of the elastic members 300 can be adjusted by providing the fluid cylinder 500 and communicating the fluid cylinder 500.

Specifically, referring to fig. 8, two of four elastic members 300 are respectively disposed on two sides of the docking track 100, four elastic members are respectively disposed symmetrically with respect to a longitudinal vertical plane of the docking track 100 and are also disposed in a docking manner with respect to a transverse vertical plane of the docking track 100, one end of each elastic member 300 is hinged to the track frame 200, the other end of each elastic member 300 is hinged to a piston rod of the fluid cylinder 500, a cylinder barrel of the fluid cylinder 500 is hinged to the docking track 100, the piston of the fluid cylinder 500 divides the fluid cylinder 500 into two chambers, wherein the chamber close to the elastic member 300 is a near-bounce chamber 510, the other chamber is a far-bounce chamber 520, the near-bounce chambers 510 of the four fluid cylinders 500 are communicated with each other through a communication pipe 530, the far-bounce chambers 520 of the four fluid cylinders 500 are also communicated with each other through a communication pipe 530, each size of the four fluid cylinders 500 is completely the same, that is, the cross-sectional areas of the cylinder barrels of the four fluid cylinders 500 are the same, thereby, through the fluid circulation of the fluid cylinder 500, the four elastic members 300 can be equally stressed, and the four elastic members 300 are symmetrically arranged relative to the vertical plane and the horizontal vertical plane of the docking rail 100, so that the resultant force of the elastic members 300 on the docking rail 100 is zero, even if the docking rail 100 is displaced in the horizontal and vertical directions after the docking is completed, and after the fluid cylinder 500 is stable, the stress of the four elastic members 300 is equally stressed, and the fluid cylinder 500 can be a hydraulic cylinder or an air cylinder.

The solution of using the fluid cylinder 500 and communicating the fluid cylinders 500 does not necessarily require the elastic members 300 to be symmetrically arranged with respect to the docking track 100, and specifically, referring to fig. 1, the elastic members 300 are not symmetrically arranged with respect to the vertical plane in the longitudinal direction of the docking track 100, and the fluid cylinder 500 is added in the solution illustrated in fig. 1, so that each elastic member 300 is connected with the docking track 100 through the fluid cylinder 500, the specific connection manner may be the same as the solution illustrated in fig. 8, except that the cylinder section area of the fluid cylinder 500 on the right side in fig. 1 is twice as large as that of the fluid cylinder 500 on the left side in fig. 1, so that the docking track 100 can move upward in a, and the fluid in the far-ammunition chambers 520 of the two fluid cylinders 500 on the left side can communicate with the fluid in the far-ammunition chambers 520 on the right side.
