Description

Technical Field

[0001] The utility model relates to a gasket device, in particular to a spherical rubber gasket for railway vehicle loading and reinforcement. Background Art

[0002] Long-distance transportation of automobiles mostly adopts railway transportation.

[0003] According to the "Rules for Railway Freight Loading and Reinforcement", the loaded vehicle should be reinforced by symmetrically pulling and tying in a "figure-eight" shape, and galvanized iron wire, steel wire rope, chain fastener, ratchet fastener, etc. are used as reinforcement equipment. One end is pulled and tied to the front / rear axle of the wheeled vehicle, and the other end is pulled and tied to the T-shaped iron or pillar groove on the side of the flat car. To protect the fixed points of the front / rear axles of the vehicle and the pillar grooves of the railway flat car from being cut by the pulling ropes, rubber gaskets are needed to play a buffering and isolating role. The currently used rubber gaskets are divided into right-angle type gaskets, rubber sheet gaskets or tubular gaskets, etc. The area and volume of these gaskets far exceed the actual requirements of the pulling and fixing "points". Among them, the right-angle type gaskets and rubber sheet gaskets are prone to displacement and deformation after being pressurized and deviate from the predetermined protection area, and need to be readjusted and reinforced again, which significantly prolongs the reinforcement operation time, and there is also a risk of gasket falling off and breaking during transportation; the tubular gasket is a non-standard reinforcement equipment and cannot be adapted to different types of pulling ropes. Moreover, to save costs, most of the tubular gasket materials are polyethylene materials, and it is difficult to meet the requirements of the "Rules for Railway Freight Loading and Reinforcement" in terms of material strength, friction coefficient, flame retardancy, etc.

[0004] Therefore, in order to shorten the loading and reinforcement operation time of the vehicle, prevent the gasket from falling off, and protect the vehicle equipment, it is necessary to design a new spherical rubber gasket for railway vehicle loading and reinforcement. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a spherical rubber gasket for railway vehicle loading and reinforcement in view of the deficiencies of the above-mentioned prior art. The gasket has a scientific and reasonable structure design, stable fixation, high friction coefficient, reduces the displacement of the vehicle during reinforcement and transportation, has good use effect, low manufacturing cost, and can be widely used.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is: a spherical rubber gasket for railway vehicle loading and reinforcement, which is characterized in that it includes a plurality of flame-retardant balls made of rubber with different sizes. The upper hemisphere of the flame-retardant ball is provided with a pulling rope groove, the pulling rope groove is a columnar groove with an arc-shaped cross-section in the axial direction and a circular cross-section, the lower hemisphere of the flame-retardant ball is provided with a fixed card slot, the fixed card slot is a columnar groove with an open triangular cross-section, and a plurality of friction strips are integrally formed and equidistantly arranged on both sides of the opening of the fixed card slot.

[0007] Preferably, a pulling rope groove is provided in the center of the coronal position of the upper hemisphere of the flame retardant ball or at a position forming an angle of degrees with the center of the coronal position, and a fixing slot is provided in the middle of the sagittal position of the lower hemisphere of the flame retardant ball, and the groove opening of the pulling rope groove is smaller than the cylindrical diameter of the pulling rope groove.

[0008] Preferably, the fixing slot is fixed to the front and rear axles or pillar slots of the vehicle to be loaded and fixed by rail, and an elastic pulling rope is passed through the pulling rope groove. The pulling rope is pressurized and firmly fixed to provide sufficient fulcrum points to fix the cushion, thereby exerting the cushion's buffering and isolation effects.

[0009] Compared with the prior art, the utility model has the following advantages:

[0010] Due to the reasonable structural design and material selection, the utility model meets the requirements of the "Railway Cargo Loading Reinforcement Rules", and the utility model can be elastically embedded in the pull rope through the design of the pull rope groove, thereby avoiding the risk of the pad falling off during reinforcement and transportation; the spherical design of the utility model increases the force depth of the pad, thereby avoiding the risk of the pad breaking during reinforcement and transportation; the design of the pull rope groove at different angles also meets the angle and force distribution requirements of the front and rear traction fixation and the "eight" traction fixation in vehicle reinforcement, and the fixation is more stable, and the force direction of the fixed slot is consistent with the direction of the pull rope groove. At the same time, the design of the friction strip increases the friction coefficient of the utility model, and significantly reduces the displacement of the pad relative to the front / rear axle or the pillar slot of the vehicle during reinforcement and transportation.
