Description

Technical Field

[0001] The utility model relates to the technical field of track gauge adjustment, in particular to a steel rail gauge adjustment tool. Background Art

[0002] During railway construction, the track gauge often needs to be adjusted. The utility model patent application with application number 200920085909.6 applies for a track gauge adjuster. The track gauge adjuster has an eccentric circular hole on the eccentric disc and a force rod on the base of the eccentric disc. When working, the eccentric circular hole is correspondingly sleeved on the threaded spike. The eccentric disc is rotated by the force rod on the base of the eccentric disc according to the principle of eccentricity. When the eccentric disc rotates, the rail is pushed to move, so as to adjust the track gauge of the rail. However, the eccentric circular hole of the utility model patent is in direct contact with the threaded spike. When the force rod applies force to the eccentric disc, the eccentric circular hole and the threaded spike are squeezed and easily wear the eccentric circular hole and the threaded spike. When the eccentric circular hole is seriously worn, the track gauge adjuster needs to be replaced, which increases the construction cost. Moreover, the force rod is welded to the eccentric disc, which increases the space occupied by the track gauge adjuster and makes it difficult to carry. Utility Model Content

[0024] like Figures 1 to 3 As shown, the utility model includes a connecting rod 1, an eccentric disc 2, an eccentric hole 3, a bolt sleeve 4 and an anti-skid rubber sleeve 5. The connecting rod 1 is detachably connected to the eccentric disc 2 and pushes the eccentric disc 2 to rotate. A scale mark is provided on the circumference of the eccentric disc 2. The eccentric hole 3 is arranged in a semicircle on one side of the eccentric disc 2. The eccentric hole 3 penetrates the eccentric disc 2 along the height direction of the eccentric disc 2. The shape of the bolt sleeve 4 matches the shape of the eccentric hole 3. The bolt sleeve 4 is detachably installed in the eccentric hole 3. The inner side wall of the eccentric hole 3 and the inner side wall of the bolt sleeve 4 are both provided with an anti-skid rubber sleeve 5.

[0025] The shortest distance from the side wall of the eccentric hole 3 to the outer wall of the eccentric disk 2 is smaller than the distance from the bottom of the rail 7 to the outer wall of the threaded spike 8, and the maximum distance from the side wall of the eccentric hole 3 to the outer wall of the eccentric disk 2 is smaller than the distance from the bottom of the sleeper shoulder to the outer wall of the threaded spike 8, so that the eccentric disk 2 can rotate between the bottom of the rail 7 and the bottom of the sleeper shoulder; the scale mark at the shortest distance from the side wall of the eccentric disk 2 to the side wall of the eccentric hole 3 is the shortest distance value, and the scale mark along the eccentric The circumferential mark of the disc 2, the scale mark at each position indicates the distance from the side wall of the current position of the eccentric disc 2 to the side wall of the eccentric hole 3. When the eccentric disc 2 is sleeved on the threaded spike 8, the outer wall of the eccentric disc 2 contacts the rail 7, and the current scale mark is recorded as the initial value. During the rotation of the eccentric disc 2, the value marked at the contact point between the eccentric disc 2 and the rail 7 is the current value. The pushing distance of the eccentric disc 2 on the rail 7 can be calculated by subtracting the initial value from the current value.

[0026] The anti-skid rubber sleeve 5 is laid along the inner wall of the eccentric hole 3 and the inner wall of the bolt sleeve 4, and the bolt sleeve 4 is embedded in the eccentric hole 3. The anti-skid rubber sleeve 5 between the bolt sleeve 4 and the eccentric hole 3 can increase the stability of the connection between the bolt sleeve 4 and the eccentric hole 3, and the anti-skid rubber sleeve 5 can also prevent the bolt sleeve 4 from directly contacting the eccentric hole 3 and causing wear of the bolt sleeve 4 and the eccentric hole 3, thereby extending the service life of the bolt sleeve 4.

[0027] During operation, the threaded spike 8 is inserted into the bolt sleeve 4. An anti-skid rubber sleeve 5 is provided between the bolt sleeve 4 and the threaded spike 8 to prevent the bolt sleeve 4 from directly contacting the threaded spike 8 and causing wear. The outer wall of the eccentric disk 2 contacts the rail 7, and the connecting rod 1 is pushed to drive the eccentric disk 2 to rotate. The eccentric disk 2 rotates around the threaded spike 8. Since the eccentric hole 3 is arranged in a semicircle on one side of the eccentric disk 2, the distances from the threaded spike 8 to the outer edge of the eccentric disk 2 are different. Therefore, the rotating eccentric disk 2 forms an outward thrust on the rail 7. The current moving distance of the rail 7 can be determined through the scale marks on the circumference of the eccentric disk 2, thereby improving the accuracy of adjusting the gauge of the rail 7. After the rail 7 moves to the target position, the gauge adjustment of the rail 7 is completed.

[0028] During use, if the bolt sleeve 4 is severely worn, the bolt sleeve 4 is taken out of the eccentric hole 3, the anti-slip rubber sleeve 5 and the bolt sleeve 4 in the eccentric hole 3 are replaced, and the anti-slip rubber sleeve 5 is sleeved in the new bolt sleeve 4 to avoid direct contact between the eccentric hole 3 and the threaded spike 8, which may cause severe wear on the side wall of the eccentric hole 3 and require replacement of the entire track gauge adjustment tool. Therefore, installing the bolt sleeve 4 in the eccentric hole 3 can reduce construction costs and improve work efficiency.

[0029] Furthermore, in order to improve the utilization rate of the track gauge adjustment tool, a plurality of eccentric holes 3 with different diameters can be arranged at intervals on the eccentric disc 2, and a bolt sleeve 4 with a corresponding diameter is installed in each eccentric hole 3, so that the track gauge adjustment tool can be sleeved on threaded spikes 8 with different diameters.

[0030] An inclined rod 6 is provided near the edge of the upper side of the eccentric disc 2 , and the end of the inclined rod 6 along the length direction is welded to the eccentric disc 2 , and the end of the inclined rod 6 away from the eccentric disc 2 is threadedly connected to the connecting rod 1 .

[0031] The inclined rod 6 is provided to facilitate the connection between the connecting rod 1 and the eccentric disc 2 , and when the eccentric disc 2 needs to be moved, the staff can move the position of the eccentric disc 2 through the inclined rod 6 .

[0032] The connecting rod 1 is a hollow steel pipe, the end of the inclined rod 6 close to the connecting rod 1 is provided with an external thread, the end of the connecting rod 1 close to the inclined rod 6 is provided with an internal thread, and the inclined rod 6 penetrates into the connecting rod 1 and is threadedly connected with the connecting rod 1.

[0033] When in use, the connecting rod 1 is threadedly connected to the inclined rod 6, and the connecting rod 1 is pushed to drive the eccentric disc 2 to rotate. After use, the connecting rod 1 is separated from the inclined rod 6, and the space occupied by the eccentric disc 2 is reduced, which is convenient to carry.

[0034] The inclined rod 6 and the connecting rod 1 have the same diameter, and the ends of the inclined rod 6 and the connecting rod 1 that are close to each other are both provided with external threads, and the inclined rod 6 and the connecting rod 1 are connected by a threaded sleeve.

[0035] When in use, one end of the threaded sleeve is threadedly connected to the inclined rod 6, and then the connecting rod 1 is connected to the end of the threaded sleeve away from the inclined rod 6, and the inclined rod 6 is connected to the connecting rod 1 through the threaded sleeve.

[0036] The bolt sleeve 4 is made of nylon.

[0037] The bolt sleeve 4 is made of nylon material, and the nylon sleeve contacts and rubs with the threaded spike 8. When the eccentric disc 2 rotates, the nylon sleeve and the threaded spike 8 are squeezed, which can reduce the damage degree of the threaded spike 8. The nylon sleeve made of nylon material has lower replacement cost and is more convenient to install and replace.

[0038] The inclined rod 6 is a solid iron rod.

[0039] The use of a solid iron rod for the inclined rod 6 can increase the weight of the eccentric disc 2, thereby avoiding the problem of insufficient pushing force and low pushing efficiency on the rail 7 due to the light weight of the eccentric disc 2.

[0040] A gasket is arranged on the outer periphery of the eccentric disc 2 .

[0041] The gasket disposed on the outer periphery of the eccentric disc 2 can prevent the eccentric disc 2 from directly contacting the rail 7, which would cause the eccentric disc 2 to damage the rail 7 during rotation, thereby extending the service life of the eccentric disc 2 and the rail 7.

[0042] When in use, the track gauge adjustment tool is first checked. If the anti-skid rubber sleeve 5 on the inner side of the bolt sleeve 4 is worn, causing the bolt sleeve 4 to directly contact the threaded spike 8, the anti-skid rubber sleeve 5 in the bolt sleeve 4 is replaced; if the bolt sleeve 4 has burrs and is severely worn, in order to ensure the quality of track gauge adjustment, the spiral sleeve 4 is replaced, the bolt sleeve 4 is first separated from the eccentric hole 3, and the anti-skid rubber sleeve 5 in the eccentric hole 3 is replaced, and then a new bolt sleeve 4 is replaced, and the anti-skid rubber sleeve 5 is laid on the inner wall of the new bolt sleeve 4, and the new bolt sleeve 4 is embedded in the eccentric hole 3. At this time, the bolt sleeve 4 and the threaded spike 8 are in contact and friction, and the threaded spike 8 is not easily damaged. At the same time, the bolt sleeve 4 and the eccentric hole 3 are not easily worn. By detachably installing the bolt sleeve 4 in the eccentric hole 3, the use of the eccentric disc 2 can be extended. After the bolt sleeve 4 is replaced, the connecting rod 1 is installed on the inclined rod 6, and the installation of the track gauge adjustment tool is completed; then, the bolt sleeve 4 is sleeved on the threaded spike 8 at the target position, and the threaded spike 8 at the target position is located in the middle position within the 73-meter range of the rail. The outer wall of the eccentric disc 2 is in contact with the rail 7, and the gauge of the rail 7 is adjusted by rotating the eccentric disc 2 through the connecting rod 1. During the track gauge adjustment process, the staff continuously monitors the track gauge until the track gauge within a range of 3 meters meets the design requirements. Then, the track gauge adjustment is completed, and the connecting rod 1 is separated from the inclined rod 6. The staff moves the eccentric disc 2 to the tool storage through the inclined rod 6, and places the connecting rod 1 and the eccentric disc 2 in one place. Separating the connecting rod 1 from the eccentric disc 2 can reduce the space occupied by the track gauge adjustment tool, which is convenient for carrying and storage.

[0043] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural transformation made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
