Description

Technical Field

[0001] The utility model relates to the technical field of segment cars, in particular to a quick-installation type wear-resistant assembly for segment cars. Background Technique

[0002] Most of the existing wear-resistant assemblies of segment cars are made of high-molecular wear-resistant plates and are fixed by sunken holes. Due to the space limitation at the use site, the thickness of the wear-resistant assembly can only be designed to be 25-30 mm. Since high-strength hexagon bolts are required for fixing, a sunken hole with a depth of 20 mm needs to be processed. In this way, the thickness of the nut is about 15 mm, and the actual use thickness of the entire wear-resistant plate is about 5 mm. The use environment at the site has sediment and is relatively humid. Therefore, there will be a lot of stone sand in the hole during actual work, which often scratches the segments. When the wear-resistant plate wears to 5 mm after a period of use, the bolt head will touch the segments. Therefore, it is necessary to replace the wear-resistant plate. When disassembling the bolts, the bolts are affected by moisture and rust, making it very difficult to disassemble. It is time-consuming and laborious, and the effective use range of the wear-resistant plate is small, resulting in frequent replacement, high cost, and waste. At the same time, after the sunken hole structure is used for a period of time, sundries are deposited in the sunken hole, the sundries damage the mating parts, and after the sunken hole structure is used for a period of time, the screws rust and are not easy to disassemble, with great difficulty. For this reason, we propose a quick-installation type wear-resistant assembly for segment cars. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a quick-installation type wear-resistant assembly for segment cars. When the disassembly amount of the nut is greater than about 3 mm, the T-shaped pull rod and the nut can be easily taken out quickly, which can greatly reduce the manual time and intensity and solve the problem that the screws are rusty and not easy to disassemble. At the same time, it also solves the problems of sundries damaging the mating parts and the small actual working thickness, and can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A quick-installation type wear-resistant assembly for segment cars, including a bottom plate;

[0005] Bottom plate: A wear-resistant plate is placed on its upper surface. Uniformly distributed T-shaped grooves are opened on the front side surface of the wear-resistant plate. Uniformly distributed open through holes are opened on the upper surface of the bottom plate. T-shaped pull rods are placed inside the T-shaped grooves respectively. The stud bolts of the T-shaped pull rods are respectively inserted into the open through holes. When the disassembly amount of the nut is greater than about 3 mm, the T-shaped pull rod and the nut can be easily taken out quickly, which can greatly reduce the manual time and intensity and solve the problem that the screws are rusty and not easy to disassemble. At the same time, it also solves the problems of sundries damaging the mating parts and the small actual working thickness.

[0006] Further, a gasket and a spring washer are sleeved on the lower end of the stud of the T-shaped pull rod from top to bottom. Nuts are threadedly connected to the lower ends of the studs of the T-shaped pull rods, and the nuts are respectively located at the lower ends of the spring washers of the studs of the same T-shaped pull rod to fix the T-shaped pull rod.

[0007] Further, the bottom walls of the T-shaped grooves are all inclined surfaces, and the openings of the T-shaped grooves become larger from outside to inside, which can quickly disassemble and assemble the T-shaped pull rod, and at the same time prevent the wear-resistant plate from shifting after being deformed by force.

[0008] Further, the lower end of the T-shaped pull rod is provided with an inclined pressing surface, and the surface of the inclined pressing surface is provided with anti-slip lines. The inclined pressing surfaces are respectively attached to the bottom walls of the adjacent T-shaped grooves, which can effectively prevent the possible loosening of the bolts caused by pressure during the working process and the slipping caused by the relative force.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: The quick-installing segment vehicle wear-resistant assembly of the present utility model has the following advantages:

[0010] 1. During installation, first insert the T-shaped pull rods into the open through holes respectively, and then screw on the nuts. At this time, the nuts are not tightened. Place the wear-resistant plate at the specified position through the T-shaped groove and then tighten the nuts. During disassembly, the T-shaped groove enables the nuts not to be completely disassembled, and the wear-resistant plate can be slid out from the side, improving the efficiency during replacement. Similar effects can also be achieved by using L-shaped fixing angle codes and changing the fixing holes to both sides of the mother plate. Due to the limited working environment, compared with the previous complete disassembly, the time is reduced by more than 1 / 2. At the same time, the open through holes effectively prevent the difficult problem of rust and difficult disassembly of the internal thread structure.

[0011] 2. The opening surface of the T-shaped groove is arranged on the high point side of the inclined surface of the wear-resistant plate, maximizing the available thickness of the wear-resistant plate, thereby increasing the utilization rate.

[0012] 3. The T-shaped groove is opened on the front side of the wear-resistant plate, and it is difficult for sundries to fall into the inside of the T-shaped groove, greatly reducing the problem of sundries precipitation. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figure 1-2 , this embodiment provides a technical solution: a wear-resistant component for a quick-installing segment car, including a bottom plate 1;

[0018] Bottom plate 1: A wear-resistant plate 2 is placed on its upper surface. Uniformly distributed T-shaped grooves 8 are provided on the front side surface of the wear-resistant plate 2. Uniformly distributed open through-holes are provided on the upper surface of the bottom plate 1. T-shaped pull rods 5 are respectively placed inside the T-shaped grooves 8. The studs of the T-shaped pull rods 5 are respectively inserted into the internal of the open through-holes. Gaskets 3 and spring washers 4 are respectively sleeved from top to bottom at the lower ends of the studs of the T-shaped pull rods 5. Nuts 6 are respectively threadedly connected to the lower ends of the studs of the T-shaped pull rods 5. The nuts 6 are respectively located at the lower ends of the spring washers 4 of the studs of the same T-shaped pull rod 5. The bottom walls of the T-shaped grooves 8 are all inclined surfaces. The openings of the T-shaped grooves 8 become larger from outside to inside. The lower ends of the T-shaped pull rods 5 are provided with inclined pressing surfaces 7. Anti-slip patterns are provided on the surfaces of the inclined pressing surfaces 7. The inclined pressing surfaces 7 are respectively attached to the bottom walls of the adjacent T-shaped grooves 8.

[0019] The working principle of a wear-resistant component for a quick-installing segment car provided by the present invention is as follows: During installation, first insert the T-shaped pull rods 5 into the internal of the open through-holes respectively, and then screw on the nuts 6. The open through-holes effectively prevent the difficult problem of rusting and difficult disassembly of the internal thread structure. At this time, the nuts 6 are not tightened. Place the wear-resistant plate 2 at the specified position through the T-shaped grooves 8 and then tighten the nuts 6. The inclined pressing surfaces 7 are respectively attached to the bottom walls of the adjacent T-shaped grooves 8. The bottom walls of the T-shaped grooves 8 are all inclined surfaces. The inclined pressing surfaces 7 increase the contact surface with the T-shaped grooves 8, with greater friction, smaller deformation of the wear-resistant plate, and increased reliability. The inclined pressing surfaces 7 are inclined at an angle of 15 degrees inward, ensuring that the T-shaped bolts will not slip off during the working process. During disassembly, the T-shaped grooves 8 enable the nuts 6 not to be completely disassembled, and the wear-resistant plate 2 can be slid out from the side, improving the efficiency during replacement. Due to the limited working environment, compared with the previous complete disassembly, the time is reduced by more than 1 / 2.
