Description

Technical Field

[0001] This utility model relates to the field of fastener fixing technology, and in particular to a railway track fastener fixing device. Background Technology

[0002] Railway track fasteners are the core components connecting rails and sleepers, forming the solid foundation of the railway track system. During track laying and maintenance, socket wrenches are used to tighten the fastener bolts connecting the rails and sleepers, ensuring that the fasteners securely fasten the rails and guaranteeing the stability and accuracy of the track gauge.

[0003] Currently, existing fastening systems contain bolts of different specifications, such as large-diameter bolts for fixing spring clips and small-diameter bolts for fixing cable clamps or other accessories. To meet the needs of use, on-site workers must carry multiple socket wrenches of different specifications, which is inconvenient and requires frequent tool changes, which also seriously reduces work efficiency and increases labor intensity. Therefore, we propose a railway track fastening device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a railway track fastener fixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A railway track fastener fixing device includes a handle, a sleeve fixedly fitted at the bottom end of the handle, a receiving groove at the center of the top end of the sleeve, a bevel gear set inside the receiving groove, threaded rods symmetrically inserted on the sides of the bevel gear set, a strip groove symmetrically opened at the top end of the sleeve, a connecting plate inserted inside each strip groove, the connecting plate being fitted on the outside of the threaded rod, a V-shaped plate connected to the bottom end of the connecting plate, a rotating rod fixedly inserted at the top of the bevel gear set, the rotating rod extending into the handle, a connecting shaft inserted inside the handle, and the bottom end of the connecting shaft being fixedly connected to the top end of the rotating rod.

[0006] Preferably, the connecting plates are provided in four sets, wherein two sets of the connecting plates are fixedly connected to two sets of V-shaped plates at their bottom ends, and the other two sets of the connecting plates are fixedly connected to two sets of clamping plates at their bottom ends.

[0007] Preferably, the connecting shaft extends to the top of the grip and is fixedly connected to a rotating block, and the side of the rotating block is fixedly connected to a connecting post.

[0008] Preferably, the rotating block is provided with a connecting strip above it, and a limiting rod is fixedly connected to the bottom end of the connecting strip. The rotating block is provided with a reserved groove that matches the limiting rod inside, and the top end of the gripping rod is provided with a limiting groove that matches the limiting rod evenly.

[0009] Preferably, there are two sets of limiting rods and reserved slots, and the two sets of limiting rods and reserved slots are symmetrically distributed about the central axis of the connecting strip.

[0010] Preferably, the sides of the V-shaped plate and the clamping plate are evenly provided with teeth, and the outer surfaces of the V-shaped plate and the clamping plate are respectively coated with an anti-corrosion coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device, equipped with a connecting shaft and a V-shaped plate, allows for the tightening of bolts of different specifications during use. The V-shaped plate, which can move laterally, eliminates the need for workers to carry different sized sleeves, thus significantly reducing the tool load on operators and lowering the risk of tool loss.

[0012] 2. This device is equipped with a connecting bar and a limiting rod. During use, the connecting bar and the limiting rod work together to limit the rotating block when it has rotated to a suitable angle, thereby preventing the threaded rod from loosening due to external forces and ensuring a tight fit between the V-shaped plate, the clamping plate and the outer wall of the bolt.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A railway track fastener fixing device includes a handle 1, with a sleeve 2 fixedly fitted at the bottom end of the handle 1. A receiving groove is formed at the center of the top of the sleeve 2, and a bevel gear set 3 is provided inside the receiving groove. The handle 1 and sleeve 2 can be made of chrome vanadium steel, which has high tensile strength and yield strength, effectively ensuring the overall structural strength of the device. Threaded rods 4 are symmetrically inserted on the sides of the bevel gear set 3. A strip groove 14 is symmetrically formed at the top of the sleeve 2, and a connecting plate 5 is inserted inside each strip groove 14. The bevel gear set 3 consists of five sets of bevel gears, four of which are fixedly fitted on the sides of the threaded rods 4 that are close to each other, and the other set of bevel gears... The wheel is fixedly sleeved at the bottom end of the rotating rod 8. Through the arrangement of five sets of bevel gears, the rotation directions of each pair of symmetrically distributed threaded rods 4 are opposite. The outer surfaces of the four sets of threaded rods 4 are provided with external threads in opposite directions, which are not shown in the figure. Therefore, when the rotating rod 8 rotates, it can drive the reversal rotation of each set of threaded rods 4, and will also drive the four sets of connecting plates 5 to be forcefully brought closer or further apart. The connecting plates 5 are sleeved on the outside of the threaded rods 4. The bottom end of the connecting plates 5 is connected to a V-shaped plate 6. The rotating rod 8 is fixedly inserted into the top of the bevel gear set 3, and the rotating rod 8 extends into the handle 1. The connecting shaft 9 is inserted into the inside of the handle 1, and the bottom end of the connecting shaft 9 is fixedly connected to the top end of the rotating rod 8.

[0017] Furthermore, refer to Figure 3 and Figure 4 It can be seen that there are four sets of connecting plates 5. Two sets of connecting plates 5 are fixedly connected to the bottom of two sets of V-shaped plates 6, and the bottom of the other two sets of connecting plates 5 are fixedly connected to two sets of clamping plates 7. By setting the other two sets of clamping plates 7, the contact area between the device and the bolt can be effectively increased, so as to ensure the reliability of the device during use, thereby ensuring that the sleeve 2 can rotate the bolt normally.

[0018] Furthermore, refer to Figure 5 It can be seen that the connecting shaft 9 extends to the top of the handle 1 and is fixedly connected to the rotating block 10, and the side of the rotating block 10 is fixedly connected to the connecting column. Through the cooperation between the rotating block 10 and the connecting column, the operating force of the operator when rotating the rotating block 10 can be reduced, thereby effectively improving the convenience of using the device.

[0019] Furthermore, refer to Figure 5It can be seen that a connecting strip 11 is provided above the rotating block 10, and a limiting rod 12 is fixedly connected to the bottom end of the connecting strip 11. A reserved groove adapted to the limiting rod 12 is opened inside the rotating block 10. A limiting groove 13 adapted to the limiting rod 12 is evenly opened at the top of the gripping rod 1. When the rotating block 10 rotates to a suitable angle, the limiting rod 12 inserted into the limiting groove 13 can limit the rotating block 10 to prevent the rotating block 10 from easily rotating due to external force. This ensures that the V-shaped plate 6, the clamping plate 7, and the bolt are tightly abutted. In addition, a rubber ring can be evenly glued to the outer surface of the limiting groove 13, and the inner size of the rubber ring is adapted to the outer size of the limiting rod 12. This ensures that the limiting rod 12 is tightly inserted into the limiting groove 13.

[0020] Furthermore, refer to Figure 5 It can be seen that there are two sets of limiting rods 12 and reserved slots, and the two sets of limiting rods 12 and reserved slots are symmetrically distributed about the central axis of the docking strip 11. By setting two sets of limiting rods 12, the limiting effect on the rotating block 10 can be effectively improved.

[0021] Furthermore, refer to Figure 4 It can be seen that the sides of the V-shaped plate 6 and the clamping plate 7 are evenly provided with teeth, and the outer surfaces of the V-shaped plate 6 and the clamping plate 7 are respectively sprayed with anti-corrosion coating. The teeth are not shown in the figure. By providing teeth, the engagement area between the V-shaped plate 6 and the clamping plate 7 and the bolt can be increased, which can effectively prevent slippage during rotation.

[0022] Working principle: In use, the operator first places the sleeve 2 on top of the fastener bolt, then pulls up the connecting strip 11, causing the limiting rod 12 to be under force, thus pulling the limiting rod 12 out of the limiting groove 13 and the rotating block 10. The operator then manually rotates the rotating block 10 to drive the connecting shaft 9 and the rotating rod 8 to rotate simultaneously. With the bevel gear set 3 at the bottom of the rotating rod 8, the four sets of threaded rods 4 can be rotated in opposite directions, and each set interacts with the connecting plates 5. The threaded engagement causes the two sets of V-shaped plates 6 and two sets of clamping plates 7 to be forced closer together and abut against the outer wall of the bolt. After rotation, the operator can insert the two sets of limiting rods 12 into the rotating block 10, and make the bottom end of the limiting rod 12 embedded in the corresponding limiting groove 13 to limit the rotation block 10. Then the operator can rotate the top of the gripping rod 1 to tighten each set of bolts, thereby realizing the fixing operation of the railway track fastener. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
