Description

TECHNICAL FIELD

[0001] The utility model relates to rail welding technical field, especially, relate to a kind of rail welding auxiliary measuring device and the rail welding equipment using the rail welding auxiliary measuring device. BACKGROUND

[0002] At present, the straightness measurement of rail mainly uses optical methods such as laser beam, for example, a kind of rail straightness measuring device provided by Chinese utility model patent CN219531970U, which includes a laser emitting assembly, a laser receiving assembly and a light point coordinate detection assembly, the laser emitting assembly and the laser receiving assembly are respectively installed at the two ends of the rail top surface of the rail to be detected, and the horizontal calibration state of the laser emitted by the laser emitting assembly is received by the laser receiving assembly is adjusted, the light point coordinate detection assembly is movably attached to the rail top surface of the rail to be detected, for obtaining and displaying the light point coordinates of the passing laser line, by comparing the deviation of the coordinates of the laser line and the coordinate origin, the straightness of the rail top surface and the rail head side where the current light point coordinate detection assembly is located can be detected.

[0003] However, the straightness measurement using laser beam has high requirements for positioning reference, the rail to be detected needs to be placed on a special detection platform for use, and there are certain requirements for the surface state of the rail to be detected. When using a fixed flash butt welding machine to flash butt weld some point rails, wing rails and other rail pieces, the light point coordinate detection assembly cannot be set at any position due to the interference of the workpiece clamping table, and the straightness measurement cannot be performed using laser beam. If the working edges of the two workpieces to be welded, such as rail and frog, or rail and rail, are not accurately adjusted in place before welding, there will be a certain misalignment between the two workpieces to be welded, which will cause joint misalignment after welding. The joint with misalignment exceeding the tolerance will be discarded, and when the misalignment is large, it will increase the difficulty of joint fine grinding and finishing.

[0004] In this regard, the welding operator usually uses a ruler to check the straightness by abutting against the working edges and rail top surfaces of the two workpieces to be welded during the rail alignment process, so as to control the misalignment difference within a certain range. However, during the repeated adjustment of the workpiece placement state, the operator needs to keep the ruler horizontal with both hands, which is laborious for the hands, and the operator also needs to adjust the alignment gauge line during this period. In addition, the flash butt welding machine clamping workpiece table only allows one arm in the height direction after the rail or frog is placed, and the narrow operation space further increases the difficulty of straightness measurement. During the joint fine grinding stage of flash butt welding, the operator also needs to repeatedly abut against the ruler to measure the joint state until the grinding is qualified. When measuring the gauge line position, two people are needed to cooperate, and a single person cannot operate. SUMMARY

[0033] As Figure 1 and Figure 2As shown, the rail welding auxiliary measuring device 1000 comprises a buckling assembly 1, a clamping assembly 2 and a locking assembly 3. The buckling assembly 1 comprises a support beam 11 and a buckling portion 12 provided on a first end of the support beam 11. The support beam 11 is used to abut the top surface of the rail head 101 of the rail 100, and the buckling portion 12 is used to abut one side of the rail head 101. The clamping assembly 2 is in sliding connection with a second end of the support beam 11. The clamping assembly 2 is used to slide along the support beam 11 to abut the side of the rail head 101 away from the buckling portion 12. The locking assembly 3 is used to lock and fix the clamping assembly 2 relative to the support beam 11.

[0034] Preferably, the buckling portion 12 is provided with a positioning groove 121. The opening of the positioning groove 121 is provided at the corner position between the inner side and the bottom surface of the buckling portion 12. It should be understood that the outer side of the buckling portion 12 refers to the side away from the rail 100, and the inner side of the buckling portion 12 refers to the side towards the rail 100 and used to clamp the rail 100. The side of the positioning groove 121 close to the clamping assembly 2 is provided with a first groove wall 1211, and the side of the positioning groove 121 away from the clamping assembly 2 is provided with a second groove wall 1212. The inclination angle of the first groove wall 1211 relative to the horizontal plane is greater than the inclination angle of the second groove wall 1212 relative to the horizontal plane, i.e. the inclination angle of the first groove wall 1211 relative to the vertical direction is smaller than the inclination angle of the second groove wall 1212 relative to the vertical direction. The inclination angles of the first groove wall 1211 and the second groove wall 1212 are different. The first groove wall 1211 is closer to the vertical direction, and the second groove wall 1212 is closer to the horizontal direction. The first groove wall 1211 is used to guide the leveling ruler 200 to be inserted into the positioning groove 121 from the bottom of the buckling portion 12. The second groove wall 1212 is used to abut the side surface of the leveling ruler 200 after the leveling ruler 200 in the positioning groove 121 is rotated to a preset angle, and to make the leveling ruler 200 slide downward along the second groove wall 1212 under the action of gravity to the state of being attached to the rail head 101.

The first groove wall 1211 can be used to guide the insertion of the leveling ruler 200 into the positioning groove 121 from the bottom of the buckling part 12. When the leveling ruler 200 is installed, the rail 100 can be avoided, and the leveling ruler 200 can be abutted against the second groove wall 1212 after being rotated by a certain angle, so that the leveling ruler 200 can slide downward along the second groove wall 1212 to the state of being closely attached to the rail head 101 under the action of its own gravity. The second groove wall 1212 supports and fixes the leveling ruler 200 while enabling the leveling ruler 200 to remain in the state of being closely attached to the rail head 101, without the need for manual holding.

When the leveling ruler 200 is closely attached to the second groove wall 1212 and slides downward to abut against the rail head 101, the upper surface of the leveling ruler 200 can be abutted and limited by the positioning wall 122, the leveling ruler 200 is multi-directionally fixed, the leveling ruler 200 is prevented from being dislocated due to welding vibration, the stability of the leveling ruler 200 is effectively improved, and the detection accuracy is improved.
