Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

With reference to fig. 1-4, the utility model provides a scotch block, including main part 1, the upper surface of main part 1 is formed with and is used for supporting along the wheel periphery first strong point 3 and the second strong point 4 of wheel 2, be equipped with on the main part 1 and be used for with main part 1 adsorbs the magnetic part 6 on the rail 5.

It should be noted that the wheel stopper of the present invention is suitable for rail trains, such as trains, and is particularly suitable for the condition that the wheel needs to be stopped to prevent the wheel from moving during maintenance of a train bogie. The scotch block is at the operation in-process, adsorb on the rail through inside magnetic part 6, and because be formed with first strong point and the second strong point along wheel periphery support wheel on the scotch block, thereby can utilize the inseparable cooperation of two strong points to restrict rocking of wheel, realize effective backstop to the wheel, make the location of scotch block reliable, the spot confusion caused scotch block pine phenomenon when preventing appearing the scotch block and not putting in place or overhauing the operation, and then avoided causing the wheel pair to rock because of scotch block pine takes off, the dislocation, the potential safety hazard that the emergence of phenomenon such as drop causes.

The arrangement positions of the first supporting point 3 and the second supporting point 4 on the main body 1 can be automatically adjusted as required, so long as the first supporting point 3 and the second supporting point 4 can be just simultaneously contacted with the periphery of the wheel 2 to achieve the purpose of stopping the wheel when the main body 1 and the wheel 2 are simultaneously positioned on a track.

In view of the purpose of saving material and facilitating design, the upper surface of the main body 1 is stepped to form the first supporting point 3 and the second supporting point 4 at two corners, respectively. It should be noted that the upper surface of the main body 1 may be in a two-step shape or a multi-step shape. When a plurality of steps are formed, the first supporting point 3 and the second supporting point 4 are formed at least at the corners of two adjacent steps, and of course, the supporting points can also be formed at the corners of each step, so that the corners of each step are contacted with the periphery of the wheel 2 in the process that the wheel 2 is stopped, thereby achieving a better stopping effect.

In this embodiment, the upper surface of the main body 1 has two stepped layers, and the first supporting point 3 and the second supporting point 4 are formed at two corners, respectively, and the two layers are designed to meet the requirement of stopping the wheel 2, so that the two layers are convenient to manufacture and save materials.

Specifically, the upper surface of the main body 1 includes a first flat surface 8, an inclined surface 9, and a second flat surface 10 connected in this order, the first flat surface 8 is formed at the junction with the inclined surface 9, and the second flat surface 10 forms the second support point 4 at an end position away from the inclined surface 9.

It should be noted that, according to the wheels with different sizes, the lengths of the first platform surface 8 and the second platform surface 10 and the inclination angle of the inclined surface 9 are adjusted adaptively so that the wheel stopper can meet the stopping requirements for the wheels with different sizes, that is, the first supporting point 3 and the second supporting point 4 are ensured to be located on the outer circumferential surface of the wheel 2 no matter what the diameter of the wheel is.

In order to reduce the abrasion to the wheel 2 in the stopping process and enhance the stopping effect by matching with the peripheral shape of the wheel 2, the first flat platform surface 8 is connected with the inclined surface 9 through an arc-shaped transition surface 11, and the first supporting point 3 is positioned on the transition surface 11. Similarly, the end of the second platform surface 10 remote from the inclined surface 9 is configured as an arc structure inclined downwards towards the third support point 7, and the arc structure is configured to cooperate with the wheel 2 tread, i.e. the second support point 4 is located on the arc structure.

It will be appreciated that the body 1 has a first end 12 adjacent the first platform face 8 and a second end 13 adjacent the second platform face 10, the first end 12 and the second end 13 being oppositely disposed. In order to facilitate the wheel stopper to extend into the bottom of the wheel 2 during use, the second end 13 is provided with a notch structure, because if the second end 13 is designed to be completely without a notch, the second end 13 is likely to contact with the tread of the wheel during extending into the bottom of the wheel, so that the stop is affected. In addition, the design of the second end 13 can further save manufacturing materials and cost compared with a complete corner-free design.

Further, the edge of second end 13 is perpendicular the equal leanin in order to form in 2 advancing direction's of wheel both sides unfilled corner structure, the top of unfilled corner structure then corresponds for being provided with second strong point 4 the arc structure, from this, the utility model discloses a scotch block adopts above-mentioned unfilled corner design can be convenient for the scotch block to stretch into from 2 bottoms of wheel, makes the arc structure contacts with the wheel tread just and realizes the backstop, prevents that bight and wheel tread from contacting the condition that leads to arc structure and wheel tread unable contact, in addition, can also contact and play the effect of no wearing and tearing backstop wheel 2 through arc structure and 2 outer peripheral faces of wheel.

In order to facilitate taking and placing of the wheel stopper and avoid clamping hands in the wheel stopper process, the first end 12 is provided with a T-shaped handle 14, the T-shaped handle 14 is welded by steel bars, and of course, the handle 14 can be set into any other shape suitable for grabbing, which is not limited herein.

In this embodiment, the main body 1 is made of steel material so as to enhance the rigidity and compressive resistance of the main body 1, and provide a good supporting and limiting effect for the stop of the wheel 2, and meanwhile, the main body has the advantage of wear resistance.

The magnetic means may be mounted in the body 1 in any suitable manner, provided that it is ensured that it can be attracted to the rail during the stopping process, in this embodiment the body 1 is provided at the bottom with at least two recesses 15 for mounting the magnetic means, which are added to the recesses 15 and reinforced. The type of the magnetic member is not limited, and may be, for example, a strong N52 type cylindrical magnet of D20 × 10 mm.

With reference to fig. 4, the application process of the scotch block of the present invention is:

the handle 14 is held by hand, the second end 13 of the main body 1 is extended into the bottom of the wheel 2 from one side of the wheel 2 to be stopped, the main body 1 is absorbed on a steel rail, so that the first supporting point 3 and the second supporting point 4 are in contact with the periphery of the wheel 2, and the wheel 2 is finally stopped.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. The technical idea of the utility model within the scope, can be right the utility model discloses a technical scheme carries out multiple simple variant, makes up with any suitable mode including each concrete technical feature. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations. These simple variations and combinations should also be considered as disclosed in the present invention, all falling within the scope of protection of the present invention.
