Description

Technical Field

[0001] The utility model belongs to the technical field of experimental instruments, and particularly relates to a deep groove sleeper combined gauge baffle. Background Art

[0002] It is well known that the gauge baffle is used to fix the rails in conjunction with spiral spikes, metal spring bars and baffle seats to prevent the lateral and longitudinal displacement of the rails and prevent the rails from tipping over, which is crucial to the safe operation of the railway. The traditional gauge baffle is made of metal material. Since the metal contains sulfides, long-term outdoor use is prone to pitting corrosion and stress corrosion cracking. Cracks are easy to extend in places where stress is concentrated, and rust will also extend inward along the cracks, causing large-scale rust. In addition, due to the high rigidity of the metal gauge baffle, strong vibrations will be generated between the rails and various components during the operation of the train. Therefore, the metal gauge baffle has problems such as short service life, high replacement frequency, poor insulation, and unsatisfactory shock absorption effect.

[0003] In view of the above problems, the gauge baffles made of non-metallic materials (epoxy fiberglass, modified nylon, etc.) are now used. Compared with metal gauge baffles, non-metallic gauge baffles have higher advantages in shock absorption, insulation, rust prevention and production cost. However, the bending strength, compression strength and fatigue resistance of non-metallic gauge baffles are all lower than those of metal gauge baffles. However, there are certain problems in the use of existing gauge baffles. When assembling the baffles and baffle seats, there are certain problems in positioning and installation. The positioning and installation are inconvenient. After installation, the gauge baffles are generally not installed during the track operation process. The baffle plate is subjected to lateral stress, that is, stress between the rails, so the baffle seat and the baffle are relatively horizontal, and the stress in the entire lateral direction is borne by bolts, so it is very easy to cause failure of the bolt structure, thereby reducing the service life of the gauge baffle and increasing the cost of maintenance and overhaul. At the same time, the connection process between the baffle seat and the baffle is connected by bolts arranged between the two. Only relying on bolts to connect the baffle and the baffle seat, it must not only withstand a large shear force, but also withstand forces in the vertical direction. Therefore, we are in urgent need of a deep groove sleeper combined gauge baffle to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-11 The specific implementation manner of the utility model is further described in detail.

[0029] Embodiment 1, a deep groove sleeper combined gauge baffle 3, including a baffle seat 1, one side of the baffle seat 1 is inclined, the baffle seat 1 is inclined to cooperate with the inclined end of the sleeper on the side away from the rail, and cooperate to resist the baffle seat 1, the sleeper and the rail to achieve the baffle seat 1 is stuck in the current position, to achieve the initial positioning of the baffle seat 1, the other side of the baffle seat 1 is opened with a U-shaped notch 2, the notch 2 is used to pass the bolt 6;

[0030] It also includes a track baffle 3 that cooperates with the baffle seat 1. The right end of the track baffle 3 is set to an inclined shape that cooperates with the baffle seat 1. The purpose of setting the track baffle 3 to an inclined structure is to match the track baffle 3. The upper end of the track baffle 3 is provided with two groups of supporting ribs 4 that are symmetrically arranged front and back. The supporting ribs 4 are in a triangular structure with the left side higher and the right side lower. The left end of the supporting rib 4 is installed with a fixing plate 9 that cooperates with the lower edge of the rail. The right end of the fixing plate 9 is connected to the triangular structure. The fixing plate 9 and the supporting rib 4 cooperate on the rail to limit the lateral movement of the rail. A vertically transparent slotted hole 5 is opened at the center of the track baffle. The slotted hole 5 cooperates with the notch 2 to pass the bolt 6. The slotted hole 5 and the notch 2 are provided with bolts 6 that are screwed in cooperation with the threaded holes pre-buried at the bottom of the baffle seat 1. The bolts 6 are screwed in cooperation with the threaded holes that have been pre-buried at the lower end of the baffle seat 1. A horseshoe-shaped spring structure 7 is arranged between the screw head of the bolt 6 and the gauge baffle 3 through a washer. The horseshoe-shaped spring provides a reverse elastic force to ensure that the bolt 6 is reliably screwed and will not easily loosen. A plurality of groups of anti-slip grooves 228 structures are arranged on the inclined surface at the right end of the baffle seat 1, which not only saves costs but also serves a certain positioning and anti-slip purpose. This embodiment is convenient for coordinated installation, and the inclined end serves the purpose of resisting lateral shear force, and the structure is simple and convenient.

[0031] Embodiment 2, on the basis of embodiment 1, auxiliary positioning support structures distributed on the four corners of the gauge baffle 3 are provided between the baffle seat 1 and the gauge baffle 3, and the auxiliary positioning support structures are used to realize the positioning and installation between the gauge baffle 3 and the baffle seat 1, and at the same time reduce the lateral relative displacement between the gauge baffle 3 and the baffle seat 1;

[0032] The auxiliary positioning support structure includes a vertically transparent stepped hole 10 with a larger upper part and a smaller lower part opened on the gauge baffle 3. The stepped hole 10 is a circular through hole structure. The inner diameter of the circular hole 13 above the stepped hole 10 is larger than the inner diameter of the circular hole 13 below. A circular column 11 with a radius smaller than the small aperture of the stepped hole 10 is arranged in the stepped hole 10. A hexagonal clamp 12 matching the large aperture above the stepped hole 10 is installed on the upper end of the column. The hexagonal clamp 12 prevents the circular column 11 from continuing to move downward in the direction of the stepped hole 10. A circular hole 13 is opened at the lower end of the column. The circular hole 13 is provided inside. The telescopic column 14 is vertically slidably connected and does not disengage. Two sets of slide grooves 22 are vertically opened in the circular hole 13. The telescopic column 14 is externally connected with a limit column 23 that vertically slides with the slide groove, thereby realizing a non-detachable structure of the telescopic column 14, so that the telescopic column 14 can only move in the vertical direction relative to the slide groove 22. A telescopic spring 15 is connected between the telescopic column 14 and the inner bottom surface of the circular hole 13. The telescopic column 14 can rotate with the column body and also perform relative displacement in the vertical direction. Therefore, when the column body rotates downward, it can drive the telescopic column 14 to move vertically. While the telescopic column 14 is rotating, it can also move in the vertical direction under the action of external force, and also includes a matching groove 16 opened at the upper end of the baffle seat 1 and placed below the stepped hole 10. A rotating clamping structure is provided between the telescopic column 14 and the matching groove 16, so that the telescopic column 14 can be clamped with the matching groove 16 when the telescopic column 14 rotates. The rotating clamping structure includes two groups of symmetrically arranged vertical grooves 24 opened at the upper end of the matching groove 16. The lower end of the vertical groove 24 is connected to a rotatably arranged guide groove 25. The guide groove 25 is opened in a manner that it is along the side of the matching groove 16. The wall rotates downward to play a guiding role. The bottoms of the two groups of guide grooves 25 are connected to the annular groove 26. The annular groove 26 is in contact with the guide groove 25. The annular groove 26 is arranged along the circumferential structure in the circumferential direction. The bayonet 27 is used to rotate along the guide groove 25 after contacting the vertical groove 24, and finally enter the annular groove 26 for clamping, so as to limit the vertical relative displacement and facilitate the withdrawal of the clamping. The telescopic column 14 is externally connected with the bayonet 27 that slides with the vertical groove 24, the guide groove 25 and the annular groove 26;

[0033] A fixing ring 17 and an annular plate 18 are respectively arranged from top to bottom in the small aperture of the stepped hole 10, and the fixing ring 17 is closer to the top. The inner diameter of the fixing ring 17 is larger than the inner diameter of the annular plate 18 and is larger than the outer diameter of the column. At the same time, the inner diameters of the fixing and annular plates 18 must ensure that the bayonet 27 structure can pass through them. An outer ring body 19 matching the fixing ring 17 is connected to the outside of the column. The outer ring body 19 and the fixing ring 17 are threadedly matched. The cooperation between the outer ring body 19 and the fixing ring 17 is to ensure that the column can be screwed. The upper end of the fixing ring 17 is connected to a first spring 20 wound in the stepped hole 10 and matched with the lower end face of the outer ring body 19. During the compression process, a spring 20 applies a reverse upward force to ensure that the threads of the outer ring body 19 and the fixing ring 17 are reliably matched, and to ensure that the column will not be easily unscrewed to avoid failure. The lower end of the outer ring body 19 is connected to a second spring 21 that cooperates with the upper end face of the baffle seat 1. If the outer ring body 19 is fully screwed, the second spring 21 will be compressed. The second spring 21 applies a reverse force between the baffle seat 1 and the gauge baffle 3, providing a reverse primary force to prevent failure of the bolt 6 structure. The second spring 21 is coaxially arranged with the first spring 20.

[0034] When the utility model is in use, the track gauge baffle 3 and the baffle seat 1 are positioned and installed through the auxiliary positioning support structure, and the circular cylinder 11 is inserted into the stepped hole 10. After the lower end of the cylinder touches the matching groove 16 below, the outer ring body 19 is threadedly matched with the fixing ring 17, and then the cylinder is screwed to move downward, and the telescopic column 14 at the lower end of the column rotates with the cylinder. The latch 27 on the telescopic column 14 rotates along the guide groove 25 after contacting the vertical groove 24, and finally enters the annular groove 26 for locking, so as to limit the vertical relative displacement. At the same time, as the cylinder is screwed, the latch 27 on the telescopic column 14 can rotate in the annular groove 26 without being affected. At the same time, as the cylinder rotates, the first spring 20 is compressed. During the compression process, the first spring 20 applies a reverse upward force to ensure that the outer ring body 19 and the fixing ring 17 are threadedly matched, so that the cylinder will not be easily unscrewed to avoid failure. If the track gauge baffle 3 and the baffle seat 1 need to be reversely and reliably locked, the second spring 21 is The outer ring body 19 is completely screwed, which will compress the second spring 21. The second spring 21 applies a reverse force between the baffle seat 1 and the gauge baffle 3, providing a reverse primary force to prevent the bolt 6 structure from failing. The circular cylinder 11 here not only assists the bolt 6 in sharing the lateral shear force when receiving the lateral force, but also applies a secondary reliable protection. At the same time, due to the existence of the first spring 20 and the second spring 21, it is ensured that the gauge baffle 3 and the baffle seat 1 are connected as a whole, and at the same time, the horseshoe-shaped spring structure 7 is prevented from failing, thereby improving a secondary protection. After installation, the bolt 6 and the horseshoe spring are installed. The utility model not only plays the role of precise positioning of the gauge baffle 3 and the baffle seat 1, but also provides secondary protection of the spring structure 7, avoids the failure of the horseshoe spring, reduces the pressure of the lateral shear force of the bolt 6, realizes the shear force sharing of the column, and saves costs at the same time, prolongs the service life and maintenance cost of the fastener. It is easy to use, simple to operate, highly practical, and suitable for promotion.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
