Detailed Description
In order to make the technical scheme of the present invention better understood by those skilled in the art, the following description is provided with reference to the accompanying drawings and the specific embodiments.
It should be noted that, in the description of the present invention, the longitudinal direction of the piggyback vehicle is taken as the front-rear direction. The front part can be the side where the head of the vehicle is located or the side where the tail of the vehicle is located; when facing forward, the left hand side is "left", and the top side of the head is "up". In the description of the present invention, the "longitudinal direction" is substantially the front-rear direction, the "lateral direction" is substantially the left-right direction, and the "vertical direction" is substantially the up-down direction, and in the lateral direction, a position relatively close to the lateral center of the railway track is inside and a position relatively far from the lateral center of the railway track is outside. In addition, in the description of the present invention, "first," "second," and the like, refer to words for convenience of description only, and are not to be interpreted as indicating or implying any particular importance or order of sequential order.
As shown in fig. 5, the body of a piggyback vehicle generally includes a body portion 1 and a carrier portion 4, which can be separated from the body portion 1 by rotating the carrier portion 4 vertically or translating the carrier portion 4 in a lateral direction. The brake pipe is arranged laterally outside the holding part 4, and when the holding part 4 is rotated vertically or translated laterally, the holding part 44 needs to be lifted upwards for a certain distance in order to avoid the interference of the brake pipe. In order to shorten the lifting distance and protect the brake pipe, the invention designs a brake pipe protecting device.
As shown in fig. 1, the brake pipe guard 10 includes a guard housing 11, and a housing cavity of the guard housing 11 is for receiving a brake pipe. The protective housing 11 is provided to protect the brake pipe on the one hand and to facilitate uniform movement of the brake pipe on the other hand. As shown in fig. 5, in the state where the bracket 4 is connected to the main body 1, the protection housing 11 is located laterally outside the side wall 42 of the bracket 4.
As shown in fig. 1, the brake pipe shield apparatus 10 further includes a shield connection member 12. As shown in fig. 2, the shield connection member 12 includes a shield inner end portion 12a, a shield outer end portion 12b, and a shield adapter portion 12c therebetween. As shown in fig. 6, the guard inner end 12a is located below the supporting portion 4, and abuts against the supporting portion 4, specifically may abut against the pressing plate 412d of the supporting portion 4; the shield outer end portion 12b is located laterally outside the shield inner end portion 12a and fixedly connected to the shield case 11. The protection adapter 12c is rotatably connected to the body 1, and specifically rotatably connected to the support 61 of the body 1.
As shown in fig. 6, in the process of connecting the supporting portion 4 with the body portion 1, the supporting force of the supporting portion 4 on the inner protecting end portion 12a is gradually increased, so that the force applied to the inner protecting end portion 12a is gradually greater than the gravity force applied to the outer protecting end portion 12b, at this time, the protecting connecting piece 12 rotates around the position (arrow direction in the figure) of connection with the body portion 1, so as to drive the protecting housing 11 to rotate upwards and inwards, and reset the protecting housing 11, and finally reach the position shown in fig. 6.
As shown in fig. 8, in the process of separating the supporting portion 4 from the body portion 1, the pressing force of the supporting portion 4 on the inner protecting end portion 12a is gradually reduced, so that the stress on the inner protecting end portion 12a is gradually smaller than the gravity on the outer protecting end portion 12b, at this time, the protecting connecting piece 12 rotates around the rotational connecting position with the body portion 1 (as shown by the arrow direction in the figure) under the action of gravity, so as to drive the protecting shell 11 to rotate downwards and outwards, and the height position of the protecting shell 11 is lowered, and finally reaches the position shown in fig. 8. Since the height position of the protective housing 11 is lowered, the interference of the protective housing 11 to the supporting portion 4 can be avoided only by lifting the supporting portion 4 upward by a short distance, so that the supporting portion 4 can smoothly rotate around the vertical direction or translate along the transverse direction.
In summary, in the process of separating the supporting part 4 from the body part 1, the protective shell 11 can automatically rotate downwards and outwards so as to avoid the supporting part 4, and the lifting distance of the supporting part 4 is effectively shortened; the protective housing 11 can be automatically reset in the process of connecting the supporting part 4 with the body part 1. The shortening of the lifting distance and the automatic avoidance and automatic resetting of the protective shell 11 can improve the separation efficiency and the connection efficiency of the supporting part 4 and the body part 1.
Further, the brake protection device 10 may further be provided with a first protection limiting member 13 (see fig. 6 and 9), where the first protection limiting member 13 is fixed to the body portion 1, specifically may be fixed to the support 61, and when the protection housing 11 rotates downward and outward to the limit position, the protection connecting member 12 abuts against the first protection limiting member 13, so that the risk that the protection housing 11 is hard to reset due to the transitional downward rotation can be prevented. In the figure, the first protection limiting member 13 is a block, and its structure and shape can be adjusted according to the need in practical implementation, and is not limited to the block.
Further, the brake pipe protecting device 10 may further be provided with a magnetic member 14 (see fig. 1), and when the protecting housing 11 is located at the lateral outer side of the supporting portion 4, the protecting housing 11 is magnetically attracted to the side wall 42 of the supporting portion 4 through the magnetic member 14. This can alleviate the vehicle-to-vehicle vibration of the brake guard and facilitate the life of the brake guard 10.
In the illustrated embodiment, the magnetic member 14 is detachably fixed to the upper surface of the protective housing 11, and may be specifically fixed by a bolt and a nut. The magnetic piece 14 is fixed on the upper surface of the protective shell 11, so that the direction of the magnetic force born by the protective shell 11 in the resetting process of the protective shell 11 is basically consistent with the resetting direction of the protective shell 11, and the magnetic force can assist the resetting of the protective shell 11. The magnetic piece 14 and the protective shell 11 can be detachably fixed, so that the magnetic piece 14 can be conveniently replaced.
Further, the brake pipe guard 10 may be further provided with a second guard stopper 15 (see fig. 8 and 9), and the guard connection 12 collides with the second guard stopper 15 when the guard housing 11 is restored to the lateral outside of the bracket 4. When the magnetic member 14 is disposed, when the supporting portion 4 moves upward, the protective connecting member 12 tends to move upward with the magnetic force, and by disposing the second protective limiting member 15, the protective connecting member 12 can be prevented from moving upward with the supporting portion 4. In the drawing, the second protection limiting member 15 is a block, and its structure and shape can be adjusted as required in practical implementation, and is not limited to the block.
In the illustrated version (see fig. 2), the guard connection 12 includes a first pivot plate 121, a second pivot plate 122, and a pivot shaft 123. The first pivot plate 121 and the second pivot plate 122 are arranged at intervals in the longitudinal direction. As shown in fig. 6, the second pivot plate 122 is closer to the mount 4 than the first pivot plate 121. The support 61 is located between the first pivot plate 121 and the second pivot plate 122, and the pivot shaft 123 sequentially passes through the first pivot plate 121, the mounting hole 612 on the support 61 and the second pivot plate 122 to connect the three together, so that the rotational connection between the protection connecting piece 12 and the body part 1 is realized. The structure is highly reliable in connection, and is not limited to this structure in practice.
In the illustrated embodiment, a positioning head (not visible in the drawing) is disposed at one end of the pivot shaft 123, a radial hole is disposed at the other end of the pivot shaft 123, and the positioning pin 1231 is inserted into the radial hole, so that the first pivot plate 121 and the second pivot plate 122 are located between the positioning head and the positioning pin 1231, which can play an axial limiting role on the pivot shaft 123, and further improve the connection reliability between the protection connection member 12 and the body 1.
In the illustrated embodiment, the shield connection 12 further includes a shield roller 125, the shield roller 125 being rotatably coupled to the second pivot plate 122. As shown in fig. 6, the second pivot plate 122 extends to the lower side of the pressing plate 412d, so that the outer peripheral surface of the shielding roller 125 abuts against the lower surface of the pressing plate 412d, and the shielding connector 12 abuts against the supporting portion 4. By providing the shield roller 125, wear in the process of abutting the shield connection 12 with the bracket 4 can be relieved.

In the illustrated embodiment (see fig. 1 and 2), the front and rear ends of the shield shell 11 are not provided with end plates, and the front and rear ends of the shield shell 11 are blocked by the shield connection 12, which facilitates the weight reduction of the brake pipe guard 10. In detail, the front end of the protective housing 11 is blocked by a first pivot plate 121 and a second pivot plate 122, the rear end is blocked by another first pivot plate 121 and another second pivot plate 122, and the first pivot plate 121 and the second pivot plate 122 are respectively provided with a protective through hole 12d for passing a brake pipe. In the drawing (see fig. 10 and 11), two guard vias 12d are respectively disposed on the first pivot plate 121 and the second pivot plate 122, and the two guard vias 12d are arranged in a staggered manner along the up-down direction. In practice, the number and arrangement of the guard vias 12d are not limited thereto.
