[0002] The axle production process requires heating, forging, surface processing and other steps. The axle is transported through parallel conveyor lines in the axle production workshop. The transfer trolley set up on the ground can replace the traditional crane to lift and transport the axle. The transfer is efficient and stable, and can realize automatic grabbing of axles. Compared with crane lifting transfer, it can adapt to the entire process of axle production.

[0003] The surface of the existing transfer trolley is installed with a telescopic structure. During the process of transferring the axle, the telescopic structure on the surface needs to be extended into one side of the conveyor line to grab the axle; at the same time, the axle needs to be transferred and transported in a direction perpendicular to the telescopic structure. The mass of the high-speed rail axle is large, and the mass of different axles is also different. The weight of the unbalanced axle will cause the trolley to lose its center of gravity and fail to work normally. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] In order to solve the problems mentioned in the background technology; Figure 1 -Attached Figure 7 A transfer device for processing a high-speed railway axle includes a carrying body 100 that moves along a first direction, a carrying end 200 that is used to carry the high-speed railway axle and is retractable along a second direction is arranged on the upper end of the carrying body 100, and the high-speed railway axle is placed on the carrying end 200 and is transferred and transported by the carrying body 100. The carrying body 100 can move along a predetermined steel rail to transport the high-speed railway axle to different positions for processing and manufacturing.

[0033] In order to ensure the stability of the load-bearing end 200 after it is extended, a hydraulic support assembly 300 is installed between the lower end of the first side of the load-bearing end 200 and the load-bearing body 100. A driving assembly for controlling the extension and retraction of the load-bearing end 200 is arranged inside the load-bearing body 100. The hydraulic support assembly 300 is connected to a hydraulic pumping device for adjusting the supporting force of the hydraulic support assembly 300. When the load-bearing end 200 is extended for a long distance and the mass of the high-speed rail axle is large, the hydraulic pumping device increases the supporting force of the hydraulic support assembly 300 to improve the stability of the load-bearing end 200 after it is extended.

[0034] When the extension distance of the load-bearing end 200 is short and the mass of the high-speed rail axle is small, the hydraulic pumping equipment reduces the supporting force of the hydraulic support assembly 300. By adjusting the supporting force of the hydraulic support assembly 300, it can better provide auxiliary support for the high-speed rail axle.

[0035] A counterweight device 400 is provided at the upper end of the second side of the load-bearing end 200. The counterweight device 400 includes a counterweight base 410 and a counterweight body 420 provided at the upper end of the counterweight base 410 and moving along the second direction. The counterweight body 420 can solve the problem of center of gravity deviation caused by carrying the axle of the high-speed railway, so that the equipment can operate stably. When the load-bearing end 200 extends along the second direction, the counterweight body 420 is controlled to move along the second direction toward the direction extending away from the load-bearing end 200 to achieve overall counterweight balance.

[0036] When the load-bearing end 200 contracts along the second direction, the counterweight body 420 is controlled to move along the second direction toward the load-bearing end 200 to achieve overall counterweight balance.

[0037] In summary, through the above structural design, by setting the hydraulic support assembly 300, the high-speed railway axle can be better supported, and by setting the counterweight device 400, the overall counterweight balance can be achieved, so that the transfer device can be more stable and reliable while ensuring the operating speed.

[0038] 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 to 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 to the bearing end 200 through a second connecting workpiece 330.

[0039] When the load-bearing end 200 moves toward the outside, the second connecting workpiece 330 moves forward with the load-bearing end 200, and the hydraulic telescopic rod 320 extends accordingly; when the load-bearing end 200 contracts toward the inside, the second connecting workpiece 330 also moves accordingly, and the hydraulic telescopic rod 320 contracts. Through the extension and contraction of the hydraulic telescopic rod 320, a triangle is formed with the load-bearing end 200 and the load-bearing body 100, so that the support for the high-speed rail axle is more stable.

[0040] The bearing end 200 includes a first bearing portion 210 and a second bearing portion 220 . The first bearing portion 210 is located inside the second bearing portion 220 and is slidably connected thereto. The second connection workpiece 330 is connected to the outer side of the lower end of the second bearing portion 220 .

[0041] The first bearing part 210 and the second bearing part 220 slide together while driving the second connection workpiece 330 to move, so that the hydraulic support assembly 300 has a better support effect.

[0042] The first end of the counterweight base 410 is rotatably connected to the bearing body 100, and a linkage plate 230 is fixed to the upper end of the bearing end 200. The inclination degree of the counterweight base 410 can be controlled by 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. During the extension of the bearing end 200, the linkage plate 230 moves synchronously along the second direction. During the synchronous movement of the linkage plate 230 along the second direction, the counterweight base 410 is controlled to deflect and tilt toward the outside.

[0043] Please refer to the attached Figure 4 Here, the linkage plate 230 is tilted toward the right side. Under normal circumstances, the linkage plate 230 is located at the left extreme position, located on the side of the first end of the counterweight base 410. During the extension of the load-bearing end 200, the linkage plate 230 can move toward the second end of the counterweight base 410.

[0044] When the linkage plate 230 extends along with the bearing end 200 , one end of the counterweight base 410 is lifted up and the tilt angle becomes larger and larger, so that the counterweight body 420 moves along the second direction toward the direction extending away from the bearing end 200 .

[0045] When the linkage plate 230 contracts with the load-bearing end 200 , the tilt angle of the counterweight base 410 becomes smaller and smaller until it reaches a horizontal state, and the counterweight body 420 moves along the second direction toward the direction in which the load-bearing end 200 extends.

[0046] A deflection roller is rotatably connected to the inner side of the second end of the counterweight base 410 , and the deflection roller abuts against the upper end surface of the linkage plate 230 .

[0047] By providing the above structure, the linkage plate 230 can better drive the second end of the counterweight base 410 to lift up when it moves.

[0048] At least two slide grooves 411 are formed on the upper end of the counterweight base 410, and a sliding frame 412 is slidably connected inside the slide groove 411. The vertical cross-section of the sliding frame 412 is U-shaped to form a limiting area. The counterweight body 420 is located in the limiting area formed by the sliding frame 412 and rolls under the action of gravity.

[0049] By setting the above structure, the counterweight body 420 can be controlled not to roll randomly under the action of gravity, but to move within the limiting area formed by the sliding frame 412, and the sliding frame 412 can slide along the sliding groove 411 under the action of gravity.

[0050] The counterweight body 420 includes a counterweight rod 421 and counterweight blocks 422 installed on both sides of the counterweight rod 421 . The counterweight blocks 422 are detachably connected to the counterweight rod 421 .

[0051] When the mass of the axle changes or the rated extension distance of the load-bearing end 200 changes, the center of gravity of the load-bearing body 100 can be kept unchanged by flexibly adding or removing the counterweight block 422 .

[0052] A control gas rod 430 is also installed on the side of the counterweight base 410 away from the load-bearing end 200. The control gas rod 430 has a gas rod telescopic end 434. The end of the gas rod telescopic end 434 is connected to the sliding frame 412. The speed and distance of the rolling of the counterweight body 420 are adjusted by controlling the gas rod 430. By providing the above structure, the counterweight body 420 can be stably controlled, and the overall counterweight can be better balanced to achieve the desired effect.

[0053] Specifically, the control gas rod 430 includes a gas rod base 431, and the gas rod base 431 is internally sealed and slidably connected with a piston 432, and the piston 432 separates the gas rod base 431 into a first control chamber 4301 and a second control chamber 4302. The gas rod telescopic end 434 is fixedly connected to the side wall of the piston 432. The first control chamber 4301 and the second control chamber 4302 are both connected to a delivery pipe with two built-in one-way valves. The first control chamber 4301 and the second control chamber 4302 each have a delivery pipe connected to a control pipe 433 with a built-in solenoid valve. A cleaning air nozzle is installed at the lower end of the second end of the counterweight base 410, and the control pipe 433 is connected to the cleaning air nozzle.

[0054] When the weight body 420 is directed toward the Figure 4 When moving in the right direction, during this process, under the pressure of the piston 432, the gas in the right second control chamber 4302 can be squeezed into the control pipe 433 and finally ejected from the clean gas nozzle; and in this process, the interior of the first control chamber 4301 increases, and the external gas can be sucked in.

[0055] When the weight body 420 is directed toward the Figure 4 When moving in the middle left direction, opposite to the above-mentioned action process, the gas in the first control chamber 4301 can be squeezed into the control pipe 433 and finally ejected from the clean gas nozzle. In this process, the second control chamber 4302 expands and sucks in the external gas.

[0056] Through the above-mentioned structural design, by controlling the opening of the solenoid valve in the control pipe 433, the counterweight body 420 can be controlled to move in a lower direction, and by controlling the closing of the control pipe 433, the counterweight body 420 can be controlled to stop; at the same time, under the action of extrusion, the gas can be blown out to the predetermined position to complete the cleaning, and the control chamber on the other side can automatically complete the suction to prepare for the next gas cleaning.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
