Description

Technical Field

[0001] The utility model relates to the technical field of rails, in particular to a rail gap self-compensating connection mechanism. Background Art

[0002] The primary functions of the track for embedded maglev vehicles include power transmission, vertical load bearing, and friction braking. These vehicles utilize slotted tracks. At the track joints, impact between the track joint and the power-receiving slider can cause arcing, or abnormal wear on the power-receiving slider due to impact and track end surface abrasion. This can also cause abnormal wear on the vehicle's brake slider.

[0003] Due to the thermal expansion and contraction of the rails, there must be a gap between the rails to accommodate the increase in the length direction of the rails caused by the thermal expansion, or a corresponding compensation mechanism must be provided.

[0004] For example, the invention patent with publication number: CN116940734A, entitled: Guide rail for vehicle and track assembly of guide rail, proposes to set a clamping assembly in the groove on the side of the track, and to open a long hole on the track. The screw connection parts connecting the clamping assemblies on both sides of the track pass through the long hole to ensure that there is a certain gap between the two adjacent sections of the track to ensure length compensation.

[0005] However, the existing track length compensation method uses a reserved gap method, resulting in a certain gap always remaining between two adjacent track sections. This cannot adaptively compensate for the increase in the length direction caused by the actual thermal expansion of the track. The two track sections cannot be tightly combined, and the track joint is large, which aggravates the impact between the track joint and the power-receiving slider and the abnormal wear of the power-receiving slider and the brake slider.

Rail connecting bar holes are provided on the rails, so that the connecting parts can move in the rail connecting bar holes, and the gap between rail 1 and rail 2 can be adjusted within a certain range, thereby adapting to the dimensional changes in the longitudinal direction of the rails caused by temperature changes, while avoiding interference between the connecting parts and the holes on the rails.

[0050] 2. The rail gap self-compensating connection mechanism of the present invention slides with the sinking platform on the top of Track 1 and Track 2 through the top plate.

DETAILED DESCRIPTION

[0066] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0067] Example 1

[0068] like Figures 1-10 As shown, this embodiment proposes a self-compensating rail gap connection mechanism, including a track 1, a track 2, and a compensation device connected between the two. A certain gap is reserved between the ends of the track 1 and the track 2 to reserve space for thermal expansion and contraction of the tracks. The compensation device is used to adaptively compensate for the gap between the track 1 and the track 2 according to the longitudinal dimensional changes caused by the thermal expansion and contraction of the tracks due to temperature changes.

[0069] In this embodiment, if Figure 3 and Figure 5 As shown, the track 1 and the track 2 2 adopt an I-shaped track. Therefore, both sides of the track 1 and the track 2 2 have grooves, the opening size of the groove is larger than the bottom size of the groove, and the two side walls of the groove are track groove inclined surfaces 1-1, and the angle between the two side walls of the groove is X°.

[0070] like Figure 5 As shown, the top surface of the track 1 is the track top surface 1-2, and the side surface of the track 1 is the track side surface 1-6.

[0071] The compensation device includes a rail positioning clamp 3 that is adapted to the shape of the rail waist of the rail 1 and the rail 2 2. The rail positioning clamp 3 is installed on the rail waist on both sides of the rail 1 and the rail 2 2. The rail positioning clamp 3 located on both sides of the rail is connected by bolts 8 and nuts 10. The rail positioning clamp 3 is used to connect, position and clamp the rail 1 and the rail 2 2.

[0072] In this embodiment, if Figure 7 As shown, the upper and lower sides of the track positioning clamp 3 are positioning inclined surfaces 3-1, and the positioning inclined surfaces 3-1 are in contact with the track groove inclined surface 1-1 at c (as shown in FIG. Figure 3 (as shown), the angle between the upper and lower positioning inclined surfaces 3-1 is also X°. By tightening the bolts 8 and nuts 10, the rail positioning clamp 3 is embedded into the groove along the contact surface. With this structure, the rail positioning clamp 3 can strictly align the contours of rail 1 and rail 2. The outer side of the rail positioning clamp 3 is the bearing surface 3-2.

[0073] The track positioning clamp 3 has four circular holes 3-3 spaced apart, and each of the track 1 and track 2 has two track connecting bar holes 1-3. The positions of the circular holes 3-3 correspond to the positions of the track connecting bar holes 1-3. It should be noted that the number of circular holes 3-3 and track connecting bar holes 1-3 is not limited to the above number; it is sufficient to ensure that track connecting bar holes 1-3 are formed on both track 1 and track 2, and that the track positioning clamp 3 has corresponding circular holes 3-3.

[0074] One end of the bolt 8 is sequentially passed through the circular hole 3-3 of the track positioning clamp 3 on one side of the track, the track connecting bar hole 1-3, and the circular hole 3-3 of the track positioning clamp 3 on the other side of the track, and then connected to the nut 10. In this embodiment, the track positioning clamps 3 on both sides of the track are connected using multiple sets of bolts 8 and nuts 10.

[0075] With the above structure, since the track connecting strip holes 1-3 are elongated holes, the bolts 8 can move in the elongated holes, so that the gap between the track 1 and the track 2 can be adjusted within a certain range, thereby adapting to the dimensional changes in the length direction of the track caused by temperature changes, while avoiding interference between the outer cylindrical surface of the bolt 8 and the hole position on the track. However, adaptive compensation of the gap between the track 1 and the track 2 cannot be achieved at present.

[0076] Therefore, further, the compensation device also includes a compensation plate 5, and the compensation plate 5 includes a top plate and a side plate. The side plate is arranged perpendicular to the top plate and connected to one side of the top plate. The top plate and the side plate form an L-shaped structure, and the two are an integrally formed structure.

[0077] The compensation plate 5 is installed on the track 1 1 and the track 2 2. Specifically, the top plate is located on the top surface of the track 1 1 and the track 2 2, and the side plates are located on the side surfaces of the track 1 1 and the track 2 2.

[0078] like Figure 2 As shown, the two ends of the top plate along the length direction of the track are set as oblique edges, the inclination directions of the two oblique edges are opposite, and the angle between the oblique edges at both ends of the top plate is Y°.

[0079] In this embodiment, the top plate is in the shape of an isosceles trapezoid.

[0080] like Figure 6 As shown, a sinking platform is provided at the top end of the track 1 and the track 2 2, and the bottom surface of the sinking platform is in the shape of a right-angled trapezoid. The sinking platform has only one side wall, and the side wall is arranged along the oblique waist of the right-angled trapezoid. The top plate is slidably connected to the sinking platforms on the track 1 and the track 2 2, and the top plate is adapted to the sinking platforms on the track 1 and the track 2 2, and the side wall of the sinking platform is adapted to the oblique side of the top plate.

[0081] The bottom surface of the sink is the vertical fitting surface 1-4 of the track, which is slidably connected to the bottom surface of the top plate (vertical fitting surface 5-1); the side wall of the sink is the side fitting surface 1-5 of the track, which is slidably connected to the oblique edge of the top plate (side fitting surface 5-2); the top surface of the top plate (top plate top surface 5-4) is flush with the top surfaces of track 1 and track 2.

[0082] The top plate is slidably matched with the sinking platforms at the top of the track 1 and the track 2 2. The extent to which the top plate slides into the sinking platforms determines the size of the gap between the track 1 and the track 2 2 compensated by the compensation plate 5.

[0083] The shape of the bottom surface of the sink is not limited to a right-angled trapezoid, and it is sufficient to ensure that the bottom surface of the sink has an inclined waist. The side walls are arranged along the inclined waist so that the side walls are adapted to the inclined edges of the top plate, and the inclined edges of the top plate are slidably connected to the side walls.

[0084] Furthermore, the side walls of the sinking platform do not adopt a straight wall structure, but a sloped structure, and the inclination direction of the side walls is inclined outward. The oblique sides of the top plate also do not adopt a straight wall structure, but a sloped structure, and the oblique sides at both ends of the top plate are inclined toward the corresponding side walls of the sinking platform. The two are adapted to each other, so that the top plate can be better confined in the sinking platform to prevent the top plate from falling out.

[0085] The side plate is located on the outside of the track positioning clamp 3, as shown in FIG. Figure 9 and Figure 10 As shown, the side panel is provided with a plurality of connecting bar holes 5-3, the positions of the connecting bar holes 5-3 corresponding to the positions of the circular hole 3-3 and the track connecting bar hole 1-3. The outer side surface of the side panel is a transverse bearing surface 5-5, and the inner side surface of the side panel is a travel control surface 5-6.

[0086] One end of the bolt 8 first passes through the connecting bar hole 5-3, and then passes through the circular hole 3-3 on the track positioning clamp 3 between the track and the side plate, the track connecting bar hole 1-3, and the circular hole 3-3 on the track positioning clamp 3 on the other side of the track, and then connects the nut 10. A washer 2 9 is provided between the nut 10 and the track positioning clamp 3.

[0087] The bolt 8 is sleeved with a sleeve 4, which also passes through the connecting bar hole 5-3. Figure 8 As shown, one end of the sleeve 4 has a flange, the outer side surface of the flange is the bearing surface 2 4-2, the other end of the sleeve 4 is the bearing surface 1 4-1, the outer surface of the sleeve 4 is the outer circular surface 4-3, and the inner side surface of the flange is the spring bearing surface 4-4.

[0088] The second bearing surface 4-2 abuts the inner side of the head of the bolt 8, and the first bearing surface 4-1 abuts the outer side (bearing surface 3-2) of the track positioning clamp 3 between the track and the side plate. A butterfly spring 7 is sleeved on the sleeve 4, one end of which abuts the outer side of the side plate, and a washer 6 is disposed between the butterfly spring 7 and the side plate. The other end of the butterfly spring 7 abuts the spring bearing surface 4-4, which provides bearing force for the butterfly spring 7. The washer 6 transmits the force of the butterfly spring 7 to the compensation plate 5. The outer cylindrical surface 4-3 serves as a guide surface for the butterfly spring 7 and the washer 6. The sleeve 4 is used to transmit the axial force of the bolt 8 and bear the elastic force of the butterfly spring 7.

[0089] According to the above structure, the compensation plate 5 is located in the sinking platform on the top surface of the track 1 and the track 2, and the top plate bevel of the compensation plate 5 is in contact with the wall of the sinking platform. Figure 4As shown, the vertical fitting surface 5-1 fits with the vertical fitting surface 1-4 of the track at a, and the side fitting surface 5-2 fits with the side fitting surface 1-5 of the track at b, and a and b form an angle Z°, where the angle Z° is the inclination angle of the side wall of the sink, and Z° is an acute angle. The compensation plate 5 can slide along the track side fitting surface 1-5. Since the butterfly spring 7 continuously provides a fitting driving force for the compensation plate 5, under the elastic action of the butterfly spring 7, the compensation plate 5 is continuously pushed toward the upper bottom direction of the right-angled trapezoid. Since a and b form an angle Z°, during the process of the butterfly spring 7 pushing the compensation plate 5 to slide, the track side fitting surface 1-5 exerts a downward force on the side fitting surface 5-2, ensuring that the top plate is always located in the sink and will not fall out. Moreover, since the angle between the oblique sides at both ends of the top plate is Y° and the side walls of the sink are adapted thereto, the side fitting surface 5-2 can always maintain a close fit with the track side fitting surface 1-5 at b, and the vertical fitting surface 5-1 can always maintain a close fit with the track vertical fitting surface 1-4 at a, and ensure the vertical bearing capacity of the compensation plate 5.

[0090] When the gap between the track 1 and the track 2 2 changes due to changes in external temperature, the compensation plate 5 will slide accordingly in the sink, changing the extent to which the compensation plate 5 slides into the sink to adapt to the gap between the track 1 and the track 2 2. The compensation plate 5 adaptively compensates for the gap between the track 1 and the track 2 2.

[0091] Since the connecting strip hole 5-3 on the compensation plate 5 is a long strip hole, when the track 1 and the track 2 2 are unevenly expanded and contracted, the long strip hole can enable the compensation plate 5 to move in the length direction of the track, thereby avoiding the phenomenon of fitting at b-1 and not fitting at b-2, or fitting at b-2 and not fitting at b-1.

[0092] The rail gap self-compensating connection mechanism provided in this embodiment is symmetrical about the center line OO.

[0093] In this embodiment, the bolts 8 can be tightened with an appropriate torque through calculation and testing to ensure that the rails can expand and contract more freely when the rails expand and contract due to external temperature changes, and to ensure that the bolts 8 will not loosen.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
