[0032] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0033] Referring to Figure 1 , the preferred embodiment of the present utility model provides a switch sleeper spacing adjustment device, including: a first clamp 2 and a second clamp 3 for respectively clamping and holding two switch sleepers 1 with the spacing to be adjusted, a scissor mechanism arranged to telescopically extend along the axial direction, and a driving assembly 4 for driving the scissor mechanism to perform telescopic movement. The scissor mechanism is disposed between the first clamp 2 and the second clamp 3, and the scissor openings at both ends of the scissor mechanism in the length direction are respectively connected to the first clamp 2 and the second clamp 3 at the corresponding ends. The driving assembly 4 is connected to the first clamp 2 and is connected to the first side of the first scissor opening at the first end of the scissor mechanism, so as to push the first side of the first scissor opening to slide relative to its second side, thereby adjusting the opening of the first scissor opening, so that the scissor mechanism shortens along the axial direction when the opening of the first scissor opening increases, or the scissor mechanism extends along the axial direction when the opening of the first scissor opening decreases.

[0034] When adjusting the distance between two switch sleepers 1 with the switch sleeper distance adjusting device of the present utility model, first, the first clip 2 and the second clip 3 are respectively clamped on the two switch sleepers 1 to accurately position the two switch sleepers 1. Then, the driving assembly 4 is manually or electrically actuated. The driving assembly 4 pushes the first side of the first scissor opening at the first end of the scissor mechanism to slide relative to the second side to adjust the opening of the first scissor opening. When the opening of the first scissor opening increases, the scissor mechanism shortens axially; when the opening of the first scissor opening decreases, the scissor mechanism elongates axially, so as to adjust the distance between the two switch sleepers 1 as required. Compared with adjusting with a manual crowbar, the distance adjustment operation of this device is simple, fast, time-saving and labor-saving, realizing rapid adjustment of the switch sleeper distance, greatly improving the laying efficiency of switch sleepers, and the length of the scissor mechanism along the axis can be steplessly adjusted by adjusting the opening of the scissor opening at the first end of the scissor mechanism, thereby realizing precise adjustment of the distance between the two switch sleepers 1 to meet the actual adjustment requirements.

[0035] Optionally, as Figure 2 shown, the scissor mechanism includes a scissor frame 5 arranged to axially expand and contract under force, a fixed seat and a movable seat 62 respectively hinged to both sides of the first scissor opening at the first end in the length direction of the scissor frame 5, and a connecting seat and a guiding seat 64 respectively hinged to both sides of the second scissor opening at the second end in the length direction of the scissor frame 5. The fixed seat and the connecting seat are arranged oppositely, the fixed seat is fixed to the first clip 2, and the connecting seat is fixed to the second clip 3. The movable seat 62 and the guiding seat 64 are arranged oppositely, the movable seat 62 is slidably connected to the first clip 2 and is relatively spaced from the fixed seat along the width direction of the first clip 2, and the driving assembly 4 is connected to the movable seat 62. The guiding seat 64 is slidably connected to the second clip 3 and is relatively spaced from the connecting seat along the width direction of the second clip 3.

[0036] During the adjustment operation, when the movable seat 62 slides relative to the fixed seat under the action of the driving assembly 4, the first side of the first scissor opening at the first end of the scissor frame 5 can be driven by the movable seat 62 to slide relative to the second side, so that the opening of the first end of the scissor frame 5 decreases or increases. When the opening of the first end decreases, the width of the scissor frame 5 becomes narrower and thus extends axially; when the opening of the first end increases, the width of the scissor frame 5 becomes wider and thus shortens axially. The arrangement of the fixed seat and the movable seat 62, and the connecting seat and the guiding seat 64 provided at both ends of the opening of the scissor frame 5 enable the scissor frame 5 to freely expand and contract under the action of an external force, realizing its axially expanding and contracting arrangement.

[0037] In this alternative solution, for the first embodiment of the scissor frame 5, as Figure 2 shown, the scissor frame 5 includes a single scissor joint formed by only crossing axially once. One side of each opening of the scissor joint is respectively hinged to the fixed seat and the movable seat 62, and the other side of each opening is respectively hinged to the connecting seat and the guiding seat 64. In this embodiment, the structure of the scissor frame 5 is simple, and the processing and preparation cost is low.

[0038] Further, as Figure 2 shown, the scissor section includes multiple groups of scissor groups 51 arranged at intervals in the height direction. Each group of scissor groups 51 includes an intersecting first scissor rod 511 and a second scissor rod 512. Both ends of the first scissor rod 511 are respectively hinged to the movable seat 62 and the connecting seat, and both ends of the second scissor rod 512 are respectively hinged to the fixed seat and the guide seat 64. In this alternative solution, the scissor group 51 generally has a triangular structure, which can effectively improve the overall stability of the scissor frame 5. Moreover, the arrangement of multiple groups of scissor groups 51 up and down in space can further enhance the overall structural stability of the scissor frame 5, thereby improving the overall working stability of the new device. Preferably, the first scissor rod 511 and the second scissor rod 512 in each group of scissor groups 51 are hinged at the intersection to form a first hinge point 513, so that the scissor group 51 forms a functional whole, further improving the overall structural stability of the scissor frame 5.

[0039] In this alternative solution, for the second embodiment of the scissor frame 5, not shown in the figure, the scissor frame 5 includes multiple scissor sections formed by intersecting multiple times along the axial direction, and the multiple scissor sections are hinged and connected in sequence along the axial direction. The fixed seat and the movable seat 62 are respectively hinged to both sides of the opening of the scissor section at the head end, and the connecting seat and the guide seat 64 are respectively hinged to both sides of the opening of the scissor section at the tail end. In this embodiment, by successively hinging and connecting the multiple scissor sections along the axial direction, the length of the scissor frame 5 along the axial direction is correspondingly increased, and thus the adjustment range of the spacing is correspondingly increased. In addition, the adjustment range of the spacing can also be correspondingly increased by widening the width of each scissor section.

[0040] Optionally, as Figure 2 shown, the scissor mechanism further includes a first guide rod group and a second guide rod group. The first guide rod group includes multiple first guide rods 71 connected in parallel at intervals in the height direction to the first clamp 2, and the movable seat 62 slidably penetrates through the multiple first guide rods 71. The second guide rod group includes multiple second guide rods 72 connected in parallel at intervals in the height direction to the second clamp 3, and the guide seat 64 slidably penetrates through the multiple second guide rods 72. Through the arrangement of the first guide rod group and the second guide rod group, on the one hand, it is used for the sliding installation of the corresponding movable seat 62 and guide seat 64, and on the other hand, it is also used for limiting and guiding the sliding of the movable seat 62 and guide seat 64.

[0041] In this alternative solution, as Figure 2As shown, the fixed seat includes multiple fixing blocks 61 that correspond one by one to multiple sets of scissors groups 51 included in each scissor link section. The multiple fixing blocks 61 are fixedly arranged one above the other in space on the first clip 2. The connecting seat includes multiple connecting blocks 63 that correspond one by one to multiple sets of scissors groups 51 included in each scissor link section. The multiple connecting blocks 63 are fixedly arranged one above the other in space on the second clip 3. Both ends of the first scissor rod 511 in each set of scissors groups 51 are respectively hinged to the movable seat 62 and the connecting block 63 at the corresponding height. Both ends of multiple second scissor rods 512 are respectively hinged to the fixing block 61 and the guiding seat 64 at the corresponding height. With such a structural arrangement of the fixed seat and the connecting seat, the weight of the scissor mechanism can be effectively reduced, thereby reducing the weight of the entire adjusting device and facilitating the moving and transporting of the device.

[0042] Optionally, as Figure 2 shown, the driving assembly 4 includes a mounting seat 41 fixed on the first clip 2 and a driving screw rod 42 threadedly passing through the mounting seat 41 and the first clip 2. The movable seat 62 is threadedly connected to the outer circumference of the driving screw rod 42. During operation, by rotating the driving screw rod 42, the driving screw rod 42 drives the movable seat 62 to slide on the first guiding rod, thereby adjusting the width of the opening at the first end of the scissor mechanism, and finally adjusting the axial length of the scissor mechanism. The adjustment operation is simple, time-saving and labor-saving, and the width of the opening of the scissor mechanism can be adjusted arbitrarily, and thus the axial length of the scissor mechanism can be adjusted arbitrarily. Or, the driving assembly 4 includes a telescopic driving member connected to the first clip 2, and the telescopic end of the telescopic driving member is connected to the movable seat 62; in this alternative solution, the telescopic driving member is a telescopic oil cylinder or a telescopic air cylinder. During operation, the telescopic oil cylinder or the telescopic air cylinder expands and contracts along its axial direction, thereby driving the movable seat 62 to slide on the first guiding rod 71 to adjust the width of the opening at the first end of the scissor mechanism. The adjustment operation is simple, time-saving and labor-saving, and the scissor mechanism works stably.

[0043] Optionally, as Figure 2 shown, the first clip 2 and the second clip 3 have the same structure. The second clip 3 includes: a clip frame 31 with a semi-clamp opening, a locking arm 32 slidably connected to the clip frame 31, and a fastener 33 for fixing the locking arm 32 and the clip frame 31. Both ends of the scissor mechanism are respectively connected to the back sides of the clip frames 31 of the first clip 2 and the second clip 3. The locking arm 32 is used to cooperate with the semi-clamp opening on the clip frame 31 to form a clamp opening with only one side open, and the size of the clamp opening is adjusted by the sliding connection between the locking arm 32 and the clip frame 31, and the two are fixed by the fastener 33 passing through both of them. When the second clip 3 clamps the corresponding switch tie 1, first slide the locking arm 32 to adjust the opening degree of the clamp opening. When the clamp opening clamps the switch tie 1, then use the fastener 33, generally a fastening screw, to lock and fix the locking arm 32 and the clip frame 31.

[0044] In this alternative solution, as Figure 2As shown in the figure, the clip holder 31 includes a push plate 311 and two cavity cross beams 312 that are arranged at intervals along the width direction of the clip holder 31 and are vertically connected to the front side of the push plate 311. A locking arm 32 is slidably connected in each cavity cross beam 312. After a fastener 33 passes through the corresponding cavity cross beam 312 and the locking arm 32, the two are fixed. During adjustment, the locking arm 32 is slid to adjust the distance between it and the push plate 311, thereby adjusting the opening degree of the clamping opening formed by enclosing the push plate 311, the cavity cross beam 312 and the locking arm 32 to adapt to the clamping of switch sleepers of different sizes and types. Then, the fastening screw is used to connect and fasten the locking arm 32 and the cavity cross beam 312. Therefore, the first clip 2 and the second clip 3 of this new type have good adaptability and can adapt to the clamping and fastening of switch sleepers of different sizes and types. In a specific embodiment of this alternative solution, a plurality of threaded holes are arranged at intervals along the length direction of the locking arm 32, so that after the fastening screw passes through the through hole opened on the cavity cross beam 312, it is threadedly connected to the corresponding threaded hole on the locking arm 32.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
