Description

TECHNICAL FIELD

[0002] As the carrier of the railway locomotive operation, the rail is first transported to the rail welding base in the standard length of 25 meters or 100 meters, and then welded and connected into a 500-meter seamless rail, and then transported to the railway line for laying. When laying, a special device is used to weld and connect the 500-meter long rail into a seamless rail on the whole line, so as to ensure the stability of the train operation.

[0003] When the rail is welded in the welding base or on site, a weld is formed at the welding position, and the top surface and side surface of the weld have different degrees of unevenness, which cannot meet the requirement of the industry standard that the weld slope is not greater than 0.3 mm. Therefore, the weld and the rails on the left and right sides of the weld need to be ground, so as to meet the requirements of the industry standard.

[0004] At present, the on-site personnel generally use handheld straight grinding machines, angle grinders and profile grinding machines to grind the welds.

[0062] Among them, the power source 2 mainly adopts a power battery pack to provide power for the equipment work.

[0063] The control mechanism 5 mainly comprises an electric control box with built-in profile analysis software and an operation panel 36, the operation panel 36 is electrically connected with the electric control box, and the polishing machine is controlled by man-machine interaction to perform polishing work.

[0064] The angle deflection mechanism 7 comprises a deflection motor 30, the polishing horizontal movement transmission mechanism 3 comprises a polishing main motor 150 and a horizontal movement motor 146, and the lifting mechanism 4 comprises a lifting motor 16. From the angle of automatic control, the power source 2, the deflection motor 30, the polishing main motor 150, the horizontal movement motor 146 and the lifting motor 16 are electrically connected with the control mechanism 5 respectively.

[0065] The angle deflection mechanism 7 mainly comprises a motor driving assembly, a gear pair assembly and related connecting pieces, etc., the polishing horizontal movement transmission mechanism 3 and the lifting mechanism 4 are driven by the deflection motor 30 to deflect left and right, so as to realize large-angle polishing work on the weld.

[0066] The walking support mechanism 6 mainly comprises a frame assembly and a wheel support assembly 10, which are used to carry other mechanisms and perform walking on the rail 0. The walking support mechanism 6 is used to mount the grinding transverse transmission mechanism 3 and the angle deflection mechanism 7, and the lifting mechanism 4 is connected to the grinding transverse transmission mechanism 3.

[0067] The grinding transverse transmission mechanism 3 mainly comprises a grinding main motor 150, a transverse motor 146, a chain wheel assembly, a transverse support frame assembly, a transmission part and a grinding wheel 155, and the automatic transverse grinding operation of the grinding assembly is realized through the chain transmission driven by the transverse motor 146.

[0068] The lifting mechanism 4 mainly comprises a driving assembly and a screw-nut threaded pair, which are used to drive the grinding mechanism to lift, and the grinding operation quality is improved by controlling the feeding amount and the feeding precision.

[0069] The rail-crossing support mechanism 1 and the rail-clamping fixing mechanism 8 are connected with the walking support mechanism 6, the rail-crossing support mechanism 1 is used to support the rail weld precision grinder, and the rail-clamping fixing mechanism 8 is used to fix the rail weld precision grinder.

[0070] Specifically, the rail-crossing support mechanism 1 mainly comprises two groups of rail-crossing rods 37, support wheels 38 and cross beams, which are used to cross the rail to support the main body of the equipment and prevent the equipment from derailing when the equipment is ground at a large angle.

[0071] The rail-clamping fixing mechanism 8 mainly comprises a fixing frame, a connecting shaft 43 and a locking screw assembly 42, which are used to fix the whole machine to prevent the equipment from moving along the extension direction of the rail 0 during the grinding process.

[0072] In the use process, firstly, the rail-crossing support mechanism 1 and the rail-clamping fixing mechanism 8 are installed to fix the whole equipment in the grinding position; then the profile analysis software built in the operation system is used to analyze the profile of the weld position to be ground, an automatic grinding scheme is formulated, and the scheme is manually audited and confirmed; finally, the control mechanism 5 is started by one key, and the equipment adjusts the angle deflection mechanism 7, the grinding transverse transmission mechanism 3 and the lifting mechanism 4 according to the grinding scheme to complete the grinding operation of the weld position.

[0073] In the rail weld precision grinder, the grinding transverse transmission mechanism 3 adopts a stepping motor to drive the grinding assembly, which replaces the manual pushing operation mode required by the grinding assembly to grind the weld, solves the problem of high labor intensity, and has the advantage of uniform grinding.

[0077] The rail weld fine grinding machine in the utility model not only solves the problems existing in the current weld polishing device, but also further improves the performance and quality of the polishing machine, and realizes the transformation of the polishing machine to miniaturization, intelligence, automation and digitization.

[0078] From the polishing process and mechanism, the rail weld fine grinding machine is fixed on both sides of the polishing weld area to ensure that the polishing grinding wheel 155 can polish the area of 0.4 meters before and after the weld position.

[0079] During polishing, all structures are adjusted to the initial state, the power battery pack is connected, the power switch is turned on, the control mechanism 5 switch is turned on, and power is supplied to the whole machine control system.

[0080] The profile of the weld area to be polished is imported into the profile analysis software, and the polishing scheme is obtained after analysis. The polishing "zero point" is adjusted manually, the automatic control button is started, the control mechanism 5 controls the lifting motor 16 and the deflection motor 30 to reach the specified position according to the polishing scheme setting value, and then the weld area is automatically polished according to the preset scheme until the desired profile is polished. The whole polishing process does not need manual intervention, but personnel need to monitor the polishing state in real time.

[0081] From the structure of the branch sub-mechanism, referring to Figure 2 , the walking support mechanism 6 includes a rack welding 9 and a leaning wheel support assembly 10, a rail crossing rod connecting assembly 12 and a lifting handle 13 connected on both sides of the rack welding 9.

[0082] The bidirectional inner side of the rack welding 9 is provided with a profiling wheel assembly 11, which ensures that the grinding wheel 155 in the polishing mechanism is always tangent to the steel rail 0, ensures the continuity of the polishing angle, and thus ensures the polishing quality.

[0083] The rail crossing rod connecting assembly 12 ensures the rapidity and accuracy of connection with the rail crossing support mechanism 1.

[0084] The lifting handle 13 ensures the convenience of equipment carrying.

[0089] Specifically, when the grinding horizontal moving transmission mechanism 3 drives the grinding device to deviate laterally relative to the rack welding 9 of the walking supporting mechanism 6 under the action of the angle deflection mechanism 7, the gravity generated by the lateral deviation forces the rack welding 9 to move left and right in the horizontal direction.
