Description

Technical Field

[0001] The utility model relates to the technical field of a dismounting and assembling device for a ball hinge of a rail transit through-channel, in particular to a dismounting and assembling device for a ball hinge of a rail transit through-channel. Background Technique

[0002] The through-channel device, also known as the windshield device, is located at the connection of two carriages of rail transit and is the connecting part of the two vehicle channels. It has good functions such as rainproof, windproof, dustproof, sound insulation, and heat insulation. The main purpose of maintaining the through-channel is to replace consumable parts. The figure shows a schematic diagram of an existing through-channel ball hinge. The through-channel ball hinge A includes: a mounting seat, a spherical plain bearing, a bushing, and a pin shaft. It is mainly used to connect the side guard plate and the link mechanism, and it is a component that is easily worn during the daily operation of the train.

[0003] The rotating shaft of the dismounting and assembling device for a ball hinge of a rail transit through-channel limits the ball hinge of the through-channel, which is convenient for the bushing and the pin shaft not to be deformed or bent when the pin shaft is struck. It is mainly limited through a limiting groove. For example, a dismounting and assembling device for a ball hinge of a rail transit through-channel with the publication number of CN220430143U limits the mounting seat through a groove. However, when the main body is struck and placed on the ground, the strong impact force directly generated may cause tiny dents, scratches, or cracks on the surface of the parts. These surface damages may gradually expand during subsequent use, affecting the accuracy and service life of the parts. Secondly, the strong impact may cause microscopic changes in the internal structure of the parts, such as generating tiny lattice dislocations or residual stresses, which may change the physical properties of the parts, such as strength, hardness, and toughness, thereby reducing their reliability and stability. Therefore, it is necessary to design a dismounting and assembling device for a ball hinge of a rail transit through-channel to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose a dismounting and assembling device for a ball hinge of a rail transit through-channel.

Specific embodiments

[0020] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-3 , a ball joint disassembly and assembly device for rail transit through channels, including a mounting block 1. A limiting frame 2 is fixedly connected to the upper end of the mounting block 1. A buffer mechanism for buffering the pin shaft is provided at the lower end of the mounting block 1. The buffer mechanism is fixedly connected to the mounting frame 5 at the lower end of the mounting block 1. A sliding block 6 is slidably connected to the inner wall of the mounting frame 5. A plurality of buffer springs 3 are provided at the upper end of the sliding block 6. The upper ends of the buffer springs 3 are connected to the lower end of the mounting block 1. A handle 8 is fixedly connected to the side wall of the mounting block 1. A through hole 4 is opened at the lower end of the mounting block 1. A through groove 7 is opened at the lower end of the sliding block 6. The cross section of the sliding block 6 is rectangular, and the sliding block 6 is in interference fit with the mounting frame 5.

[0022] A plurality of positioning mechanisms for positioning the pin shaft mounting seat are provided at the upper end of the mounting block 1. The positioning mechanisms include a plurality of positioning posts 11 fixedly connected to the upper end of the mounting block 1. Two limiting rods 10 penetrate through the side wall of the limiting frame 2.

[0023] In the present utility model, a mounting ring 16 is fixedly connected to the side wall of the mounting block 1. The side wall of the handle 8 is threadedly connected to the mounting ring 16, so that the handle 8 can be screwed out of the mounting ring 16, enabling the handle 8 to be disassembled from the mounting block 1, which is convenient for transportation and storage.

[0024] In the present utility model, an anti-slip sleeve 9 is provided on the side wall of the handle 8 to prevent slipping. A lifting ring 14 is fixedly connected to the side wall of the mounting block 1, which is convenient for taking the device.

[0025] In the present utility model, a fixing block 12 is fixedly connected to the side wall of the mounting frame 5. A threaded hole is opened at the upper end of the fixing block 12, so that after the handle 8 is screwed out, it can be screwed into the threaded hole and placed on the fixing block 12 to avoid random placement of the handle 8.

[0026] In the present utility model, a pulling ring 13 is fixedly connected to the side wall of the limiting rod 10, which is convenient for pulling the limiting rod 10. Two placing blocks 15 are fixedly connected to the side wall of the mounting block 1. A placing hole is opened at the upper end of the placing block 15, and the limiting rod 10 can be placed in the placing hole and placed on the placing block 15.

[0027] In the initial state, the limiting rod 10 is placed on the placing block 15.

[0028] In use, an operator can hold the handle 8 and place the sliding block 6 on the ground or a flat surface. Place the mounting seat of the assembled gangway ball joint in the limiting frame 2 and limit it by the four inner walls of the limiting frame 2. At this time, the pin shaft of the gangway ball joint stands upright as shown in the figure. Then, use a hammer and a nylon block to cooperate and strike the end of the pin shaft, so that the spherical plain bearing, the bushing and the pin shaft of the gangway ball joint are separated from the mounting seat. The pin shaft is driven into the through hole 4 and the through slot 7. After separation, tools such as a wrench socket can be used to completely separate the spherical plain bearing, the bushing and the pin shaft, so as to replace with new accessories;

[0029] Tools such as a wrench socket can also be used to install the spherical plain bearing, the bushing and the pin shaft into one body. Then, insert the pin shaft reversely into the through hole 4 and the through slot 7. Place the mounting seat in the limiting frame 2 and limit it by the four inner walls of the limiting frame 2, and cooperate with a hammer to press the spherical plain bearing in;

[0030] During the knocking process, the movement of the mounting block 1 during the knocking process can be avoided by holding the handle 8. At the same time, the mounting block 1 will move downward during the knocking process. The mounting frame 5 slides on the side wall of the sliding block 6, and multiple buffer springs 3 will deform, converting the impact energy into elastic potential energy, which can absorb and disperse part of the energy generated by the hammer knocking, thereby reducing the impact force transmitted to the objects being knocked (the shaft and the bushing), slowing down the transmission of the impact, and reducing the possibility of damage to the shaft and the bushing;

[0031] When the mounting seat is placed in the limiting frame 2, the positioning holes on the mounting seat are aligned with the positioning posts 11, so that the four positioning posts 11 further limit the position of the mounting seat. Insert two limiting rods 10, so that the mounting seat will not fall off or jump up from the mounting block 1 during knocking.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and practical concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
