The transfer trolley is arranged on the ground to replace the traditional axle hoisting and conveying by the crane, and the transfer trolley has high transfer efficiency, stability, and can realize automatic grabbing of the axle.

DETAILED DESCRIPTION

[0032] The application is further illustrated below in conjunction with the drawings and examples.

[0033] To solve the problems mentioned in the background art; refer to the accompanying Figure 1 - the accompanying Figure 7 A transfer device for high-speed rail axle machining, comprising a bearing body 100 moving along a first direction, a bearing end 200 for bearing high-speed rail axles and telescoping along a second direction is arranged at the upper end of the bearing body 100, the high-speed rail axles are placed on the bearing end 200 and are transported by the bearing body 100, the bearing body 100 can move along a predetermined rail to transport the high-speed rail axles to different positions for machining and manufacturing.

[0034] In order to ensure the stability of the bearing end 200 after extension, a hydraulic support assembly 300 is installed between the first side lower end of the bearing end 200 and the bearing body 100, a drive assembly for controlling the telescoping of the bearing end 200 is arranged inside the bearing body 100, and the hydraulic support assembly 300 is communicated with a hydraulic pumping device for adjusting the size of the supporting force of the hydraulic support assembly 300; when the bearing end 200 extends a long distance and the high-speed rail axle has a large mass, the hydraulic pumping device increases the supporting force of the hydraulic support assembly 300 to improve the stability of the bearing end 200 after extension.

[0035] When the bearing end 200 extends a short distance and the high-speed rail axle has a small mass, the hydraulic pumping device reduces the supporting force of the hydraulic support assembly 300, and by adjusting the size of the supporting force of the hydraulic support assembly 300, the high-speed rail axle is better assisted and supported.

[0036] The counterweight device 400 is arranged at the upper end of the second side of the bearing end 200, and includes a counterweight base 410 and a counterweight body 420 arranged at the upper end of the counterweight base 410 and movable along the second direction; the counterweight body 420 can solve the phenomenon of gravity center deviation caused by bearing the high-speed rail axle, so that the device can stably operate. When the bearing end 200 extends along the second direction, the counterweight body 420 is controlled to move along the second direction away from the direction in which the bearing end 200 extends, so as to realize overall counterweight balance.

[0037] When the bearing end 200 retracts along the second direction, the counterweight body 420 is controlled to move along the second direction towards the direction of the bearing end 200, so as to realize overall counterweight balance.

[0038] In summary, through the above structure design, the hydraulic support assembly 300 can better assist the support of the high-speed rail axle, and the counterweight device 400 can realize overall counterweight balance, so that the transfer device is more stable and reliable while ensuring the running speed.

[0039] Specifically, the hydraulic support assembly 300 includes a hydraulic telescopic rod 320, the outer side of the base end of the hydraulic telescopic rod 320 is connected with the bearing body 100 through a first connecting workpiece 310, and the outer side of the telescopic end of the hydraulic telescopic rod 320 is connected with the bearing end 200 through a second connecting workpiece 330.

[0040] When the bearing end 200 moves towards the outside, the second connecting workpiece 330 moves forward with the bearing end 200, and the hydraulic telescopic rod 320 is elongated; when the bearing end 200 retracts towards the inside, the second connecting workpiece 330 also moves, and the hydraulic telescopic rod 320 is retracted, and the hydraulic telescopic rod 320, the bearing end 200 and the bearing body 100 form a triangle, so that the support of the high-speed rail axle is more stable.

[0041] The bearing end 200 includes a first bearing part 210 and a second bearing part 220, the first bearing part 210 is located inside the second bearing part 220 and is in sliding connection with the second bearing part 220, and the second connecting workpiece 330 is connected with the outer side of the lower end of the second bearing part 220.

[0042] The first bearing part 210 and the second bearing part 220 slide while driving the second connecting workpiece 330 to move, so that the hydraulic support assembly 300 has a better supporting effect.

[0043] The first end of the counterweight base 410 is rotationally connected with the bearing main body 100, the upper end of the bearing end 200 is fixed with a linkage plate 230, the inclination degree of the counterweight base 410 can be controlled through the linkage plate 230, the upper end surface of the linkage plate 230 is inclined and the linkage plate 230 is located on the deflection path of the counterweight base 410, the linkage plate 230 moves synchronously along the second direction in the process of the bearing end 200 extending, the linkage plate 230 controls the counterweight base 410 to deflect and incline outwardly in the process of the linkage plate 230 moving synchronously along the second direction.

[0044] Specifically refer to the accompanying drawings Figure 4 The linkage plate 230 inclines to the right side here, the linkage plate 230 is located at the left limit position in the normal state, located on the first end side of the counterweight base 410, the linkage plate 230 can move to the second end direction of the counterweight base 410 in the process of the bearing end 200 extending.

[0045] When the linkage plate 230 extends with the bearing end 200, one end of the counterweight base 410 is lifted, the inclination angle becomes larger and larger, so that the counterweight main body 420 moves along the second direction to the direction away from the bearing end 200 extending.

[0046] When the linkage plate 230 retracts with the bearing end 200, the inclination angle of the counterweight base 410 becomes smaller and smaller until the horizontal state, the counterweight main body 420 moves along the second direction to the direction of the bearing end 200 extending.

[0047] The second end of the counterweight base 410 is rotationally connected with a deflection roller, the deflection roller abuts against the upper end surface of the linkage plate 230.

[0048] Through the above structure, the linkage plate 230 can better lift the second end of the counterweight base 410 when moving.

[0049] The upper end of the counterweight base 410 is provided with at least two sliding grooves 411, a sliding frame 412 is slidably connected in the sliding groove 411, the vertical section of the sliding frame 412 is U-shaped to form a limiting area, the counterweight main body 420 is located in the limiting area formed by the sliding frame 412 and rolls under the action of gravity.

[0052] When the mass of the axle changes or the rated extension distance of the load end 200 changes, the counterweight 422 can be flexibly added or reduced to keep the gravity center of the load main body 100 unchanged.

[0053] The control air rod 430 is further installed on the side of the counterweight base 410 away from the load end 200, and has an air rod telescopic end 434 connected to the sliding frame 412 at the end. The speed and distance of the rolling of the counterweight main body 420 are adjusted by the control air rod 430. The counterweight main body 420 can be stably controlled by the above structure, and the overall counterweight balance can be better achieved to achieve the expected effect.

[0055] When the counterweight main body 420 moves towards the right side of the middle direction, in this process, under the extrusion of the piston 432, the gas in the right second control chamber 4302 can be extruded into the control pipeline 433 and finally sprayed out from the cleaning air nozzle; and in this process, the first control chamber 4301 is increased, and the gas outside can be sucked in. Figure 4 When the counterweight main body 420 moves towards the left side of the middle direction, the process is opposite to the above-mentioned action process, and the gas in the first control chamber 4301 can be extruded into the control pipeline 433 and finally sprayed out from the cleaning air nozzle. In this process, the second control chamber 4302 is increased, and the gas outside can be sucked in.

[0056] Figure 4 Through the above structure design, by controlling the electromagnetic valve in the control pipeline 433 to be opened, the counterweight main body 420 can be controlled to move towards the lower direction, and by controlling the control pipeline 433 to be closed, the counterweight main body 420 can be controlled to stop; at the same time, under the extrusion, the gas can be blown out to the predetermined position to complete cleaning, and the control chamber on the other side can automatically complete the gas suction to prepare for the next gas cleaning.
