Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the invention, whereby the invention is not limited to the specific embodiments disclosed below.
In the description of the present invention, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.
In the description of the present invention, it will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.
Conventionally, for the dismounting operation of the coupler buffer 45, the coupler buffer 45 is pressed by an oil cylinder to compress the coupler buffer 45, and the coupler buffer 45 can be dropped from the vehicle body 30 after being compressed. However, when the coupler buffer 45 falls off from the car body 30, the coupler buffer 45 is heavy, and no special bearing device is provided, so that the coupler buffer 45 is easy to collide with the coupler yoke 48 after being disassembled, and thus, safety accidents are caused, and safety is low.
In one embodiment, referring to fig. 1 to 9, a device for assembling and disassembling a coupler buffer 45 includes a main push cylinder 10 and a positioning member 20. The main pushing cylinder 10 is configured to be disposed in the hook tail frame 41, and the main pushing cylinder 10 includes a pushing end 11 and a bottom end 12 disposed opposite to the pushing end 11. The pushing end 11 is adapted to interfere with the front slave plate 46. The bottom end 12 is provided with an inlet pipe 121. The pipe joint 13 is connected to the pipe 121, the pipe joint 13 is used for connecting with a pump station, the pipe 121 and the pipe joint 13 are both located in the concave portion 31 of the bottom surface of the vehicle body 30, and the pipe joint 13 is located outside the tail hooking frame 41. The positioning piece 20 is configured to be disposed in the mounting hole 411 of the coupler yoke 41, and the positioning piece 20 is in interference fit with the bottom end 12.
Specifically, the main pushing cylinder 10 may be an oil cylinder, a hydraulic cylinder, an air cylinder, or an electric cylinder.
The above-mentioned dismounting device of coupler buffer 45, setting element 20 plays the positioning action to main jar 10 that pushes away, extrudes coupler buffer 45 when the push end 11 of main jar 10 stretches, and coupler buffer 45 is compressed the back, and preceding slave plate 46 no longer closely contradicts cluster board seat 47, and coupler buffer 45 breaks away from in the concave part 31 of the bottom surface of automobile body 30 under the effect of gravity together with the yoke 41, is convenient for pack into main jar 10 and setting element 20 in automobile body 30 and carry out the dismouting operation on the one hand, and the dismouting operation process is comparatively simple on the other hand. In addition, since the inlet pipe 121 and the pipe joint 13 are both located in the recess 31 of the bottom surface of the vehicle body 30, and the pipe joint 13 is located outside the coupler yoke 41, in the instant when the coupler buffer 45 and the coupler yoke 41 are separated from the vehicle body 30 from the recess 31 of the bottom surface of the vehicle body 30, the pipe fitting externally connected with the pipe joint 13 can drop down directly, so that the pipe fitting can avoid the coupler yoke 48, thereby avoiding collision with the coupler yoke 48 and improving safety.
Further, referring to fig. 2 and 3, a positioning groove 122 is formed in a middle portion of the end face of the bottom end 12, the positioning member 20 is provided with a positioning boss 21, and the positioning boss 21 is disposed in the positioning groove 122. In this way, after the positioning groove 122 is matched with the positioning boss 21 of the positioning piece 20, the main pushing cylinder 10 is ensured to keep the acting point of the output force at the middle part of the front slave plate 46 when pushing the front slave plate 46, and the parallel equidistant compression of the two ends of the front slave plate 46 is ensured, so that the buffer can be smoothly extruded, the bad phenomenon that the buffer cannot be extruded when receiving the oblique acting force is avoided, and the buffer is conveniently compressed to separate the front slave plate 46 from the cluster plate seat 47.
Further, referring to fig. 3, the side wall of the positioning member 20 includes at least two portions, wherein one portion of the side wall is provided with the positioning boss 21, and the other portion of the side wall is an arc surface, and the arc surface is used for abutting against the wall of the mounting hole 411. Specifically, the positioning member 20 is a pressing pin, and a cross section of the pressing pin perpendicular to the axial direction is, for example, a semicircular surface.
Further, referring to fig. 3 to 8, the dismounting device of the coupler buffer 45 further includes a hydraulic lock 14. The pipe joint 13 is connected with the inlet pipe 121 through the hydraulic lock 14. The number of the inlet pipe 121 and the number of the pipeline connectors 13 are two, and the two pipeline connectors 13 and the two inlet pipes 121 are correspondingly arranged one by one. The two inlet and outlet pipes 121 are respectively located at two sides of the positioning member 20. Thus, on the one hand, after the coupler buffer 45 is compressed by the main push cylinder 10 by a preset amount, the main push cylinder 10 does not compress the coupler buffer 45, that is, the pump station stops supplying oil or gas, at this time, under the action of the hydraulic lock 14, the compression state of the coupler buffer 45 is continuously ensured, and the influence of the rebound of the coupler buffer 45 on the dismounting operation of the coupler buffer 45 can be avoided.
Further, referring to fig. 3 to 9, the pipe joint 13 is disposed on the bottom surface of the hydraulic lock 14, and the direction of oil inlet and outlet of the pipe joint 13 is perpendicular to the bottom surface of the hydraulic lock 14. That is, the oil inlet and outlet direction of the pipe joint 13 is perpendicular to the axial direction of the main push cylinder 10, and the pipe joint 13 faces the track, so that collision between the inlet and outlet pipe 121 and the vehicle body 30 when the main push cylinder 10 falls along with the coupler buffer 45 when the coupler buffer 45 is disassembled after the main push cylinder 10 is connected with the pump station can be avoided to a certain extent.
In one embodiment, referring to fig. 10 to 19, the dismounting device of the coupler buffer 45 further includes a handling mechanism 50 for handling the coupler buffer 45. The carrying mechanism 50 includes a moving base 51 and a lifting mechanism 52. The lifting mechanism 52 is disposed on the moving base 51, and the lifting mechanism 52 is used for lifting the coupler buffer 45. Specifically, the lifting mechanism 52 is a hydraulic lifting table, an air cylinder lifting mechanism 52, an oil cylinder lifting mechanism 52, a motor screw lifting mechanism 52, or an electric cylinder lifting mechanism 52. The lifting mechanism 52 in this embodiment is a hydraulic lifting table including, but not limited to, a scissor lift, a telescopic lift, or a folding lift. In this way, when the coupler buffer 45 needs to be disassembled, the movable base 51 can be moved to a position corresponding to the coupler buffer 45 below the car body 30, for example, a bracket 53 which is suitable for the coupler buffer 45 is arranged above the lifting mechanism 52, the coupler buffer 45 is separated from the car body 30 and falls onto the bracket 53, the coupler buffer 45 is lifted by the bracket 53, the movable base 51 is pushed, the movable base 51 moves with the lifting mechanism 52, and the lifting mechanism 52 moves with the coupler buffer 45 from the lower side of the car body 30; after the coupler buffer 45 is horizontally moved out, the lifting mechanism 52 moves up and down to lower and move away the coupler buffer 45, so that the disassembly operation of the coupler buffer 45 is completed. The installation operation of the coupler buffer 45 is exactly opposite to the disassembly operation of the coupler buffer 45, and a detailed description thereof will be omitted.
Note that, fig. 12 and 13 schematically show that the coupler 42 is mounted on the bracket 53 above the lifting mechanism 52, so as to lift the coupler 42. It will be appreciated that the support 53 above the lifting mechanism 52 may be designed to be matched with the coupler buffer 45 according to needs, and be used for installing the coupler buffer 45, and lifting the coupler buffer 45, so as to facilitate the disassembly and assembly of the coupler buffer 45.
Further, referring to fig. 10 to 13, one side of the moving base 51 is provided with two or more first travelling wheels 511 at intervals. The other side of the movable base 51 is provided with more than two spaced second travelling wheels 512, and the first travelling wheels 511 and the second travelling wheels 512 are respectively used for travelling on two rails 60 of a railway. Thus, the movable base 51 can conveniently walk on the rail 60 of the railway, and the coupler buffer 45 of the train on the railway is conveniently assembled and disassembled on line. Of course, the present invention is not limited to application to a railway train, and may be applied to a train that moves on the ground, and the coupler buffer 45 of a truck on the ground may be removed. Specifically, the two or more first traveling wheels 511 are in one-to-one correspondence with the two or more second traveling wheels 512, and are connected by a connecting shaft 513.
Further, referring to fig. 11 to 15, the movable base 51 includes two movable blocks 514 disposed at intervals, and two cross beams 515 disposed at intervals. The two ends of the cross beam 515 are respectively connected to two moving blocks 514. The first travelling wheel 511 and the second travelling wheel 512 are respectively disposed on the two movable blocks 514.
Further, referring to fig. 11 to 15, the movable base 51 further includes one or more rollover prevention components disposed on the movable block 514. The rollover prevention assembly is configured to be disposed on a side of the rail 60. In this way, under the action of the rollover prevention component, the adverse phenomenon of rollover in the process of lifting the coupler 42 or the coupler buffer 45 by the lifting hook 544 of the carrying mechanism 50 can be avoided. Specifically, the movable block 514 is provided with two through holes 516 respectively located at two sides of the rail 60, and the rollover prevention assembly comprises a rail locking fork 517 and two rail locking pins 518. Two leg portions of the rail locking fork 517 are respectively inserted into the two through holes 516 and located at both sides of the rail 60, and two rail locking pins 518 are respectively installed on the two leg portions.
In one possible solution, the rollover prevention assembly may also be two rollover prevention hooks respectively disposed on two sides of the rail 60, where the two rollover prevention hooks are respectively disposed on two sides of the rail 60 to play a role in rollover prevention. The rollover prevention hook body is detachably arranged on the movable seat block 514 or is integrally formed with the movable seat block 514.
