[0006] By arranging a conveying mechanism inside the machine, the conveying mechanism cooperates with the assembling mechanism to centrally convey and assemble the pillow block, traction beam and coupler seat, and the three are assembled into one at the same time. The simultaneous welding of the three is completed in cooperation with the operation of the welding arm. At the same time, an additional flipping mechanism can flip the pillow block, traction beam and coupler seat after being welded together, and flip the weld position that the welding arm cannot reach upward, so as to cooperate with the continued operation of the welding arm to complete the welding processing of the entire traction and pillow buffer, realize the assembly line continuous production of the traction and pillow buffer, and at the same time eliminate the steps of manual welding, thereby greatly improving the functionality and perfection of traditional equipment.

[0009] In a preferred embodiment, each group of the assembly parts includes a first-class assembly part installed on the top of the first-class conveyor belt, a second-class assembly part installed on the top of the second-class conveyor belt, and two third-class assembly parts symmetrically installed on the top of the third-class conveyor belt, the pillow beam is placed inside the first-class assembly part, the traction beam is placed inside the second-class assembly part, and the coupler seat is placed between two symmetrical third-class assembly parts.

[0010] An assembly part is provided on the top of a type I conveyor belt, a type II conveyor belt and a type III conveyor belt. The assembly part includes a type I assembly part, a type II assembly part and two symmetrically distributed type III assembly parts. The three types of assembly parts are used to carry and transport a sleeper beam, a traction beam and a coupler seat respectively, which ensures the structural stability during transportation and facilitates the subsequent centralized assembly of the three.

[0012] A first partition and a second partition are arranged on the top of the machine platform, which cooperate with the side wall of the machine platform to separate the first, second and third conveyor belts in sequence, while maintaining the stability of the three conveyor belts when conveying the pillow beam, traction beam and coupler seat. A first port is arranged at the end of the first partition, a second port is arranged at the end of the second partition, and a clamping port is arranged on the side wall of the machine platform. When the pillow beam, traction beam and coupler seat run to the side of the first port, the second port and the clamping port along with the conveyor belt, the pillow beam, traction beam and coupler seat are extruded by the flipping mechanism, so that the pillow beam, traction beam and coupler seat move through the three ports in sequence and clamp each other. The extrusion force, the side reinforcement ribs of the pillow beam and the positional relationship of the clamping port are used to maintain the stability of the pillow beam, traction beam and coupler seat during assembly, thereby ensuring the stability of the welding arm when welding the three.

[0013] In a preferred embodiment, the flipping mechanism also includes a hydraulic clamp installed on the outside of the output end of the electric push rod, a damping member is arranged between the output end of the electric push rod and the hydraulic clamp, the hydraulic clamp includes a clamping platform fixed to the end of the electric push rod, a clamping claw is rotatably installed on the side of the clamping platform, and a hydraulic pipe is connected to the end of the clamping platform; a clamping part is installed on the output end of the first motor, and the clamping part is horizontally distributed on the outside of the clamping port, and the clamping part includes a clamping sleeve installed on the outside of the output end of the first motor, a comb tooth groove is opened at the end of the clamping sleeve, and the comb tooth groove is engaged with the ribs of the reinforcing rib, and an auxiliary part is installed on the top of the second partition, and the auxiliary part is distributed on the side of the second port.

[0017] It can be seen from the above that the rail vehicle tie-down welding device provided by the present invention has the following technical effects.

[0018] First, by respectively arranging a first type of conveyor belt, a second type of conveyor belt and a third type of conveyor belt on the top of the machine, the three types of conveyor belts carrying the assembly part are used to centrally convey the bolster, the traction beam and the coupler seat respectively, and the top of the machine is provided with a first partition and a second partition, which cooperate with the side wall of the machine to sequentially separate the first type of conveyor belt, the second type of conveyor belt and the third type of conveyor belt, while maintaining the stability of the three types of conveyor belts when conveying the bolster, the traction beam and the coupler seat, so that the bolster, the traction beam and the coupler seat are on the same horizontal line, and the end of the first partition is provided with a first port, the end of the second partition is provided with a second port, and the side wall of the machine is provided with a first port. A clamping port is provided. When the bolster, traction beam and coupler seat are moved to the sides of the first port, the second port and the clamping port along with the conveyor belt, the bolster, traction beam and coupler seat are moved through the three ports and clamped synchronously in cooperation with the extrusion of the flipping mechanism. The extrusion force and the positional relationship between the side reinforcement ribs of the bolster and the clamping port are utilized to maintain the stability of the bolster, traction beam and coupler seat during assembly. The three are assembled and welded centrally in cooperation with the operation of the assembly mechanism and the welding arm. Therefore, under the premise of maintaining stability during assembly, the working efficiency of traditional welding equipment is greatly improved through assembly line assembly.

[0019] Secondly, an electric push rod and a first motor structure mounted on the top of the connecting part are respectively arranged on both sides of the machine, and the output shaft of the electric push rod is extended to drive the hydraulic clamp, so that the hydraulic clamp clamps and pushes the pillow beam, the traction beam and the coupler seat, so that the three are assembled close to each other, and at the same time, the reinforcing ribs on the side of the pillow beam are engaged into the inside of the clamping part to complete the fixation of the pillow beam, the traction beam and the coupler seat. After the welding of the three is completed with the welding arm, the extension of the connecting part and the rotation of the first motor are used to drive the welded pillow beam, the traction beam and the coupler seat to flip, so as to fix the leakage existing in the initial welding of the three. The seams are exposed, and the welding arm is operated twice to complete the repair of the welds, thereby eliminating the need for workers to visually inspect and repair the seams after welding in traditional equipment, thereby solving the disadvantages of using traditional equipment. While the pillow beam, traction beam and coupler seat are flipped after welding, the support plate structure additionally arranged on the top of the second partition can be lifted by the rotation of the second motor, thereby supporting the flipped pillow beam, traction beam and coupler seat, thereby ensuring the structural stability of the three when the welding arm performs secondary welding on the pillow beam, traction beam and coupler seat, thereby ensuring the integrity of the operation of this equipment.

The slowly rotating conveying mechanism 7 will convey the bolster beam 4, the traction beam 5 and the coupler seat 6 toward the direction of the flipping mechanism 9 until the bolster beam 4, the traction beam 5 and the coupler seat 6 are flush with the flipping mechanism 9. At this time, the conveying mechanism 7 stops running, and the flipping mechanism 9 starts running, by clamping the coupler seat 6 and slowly pushing it, so that the coupler seat 6 moves along the side of the assembly mechanism 8 and pushes the bolster beam 4 and the traction beam 5 in sequence until the reinforcing rib 401 on the side of the bolster beam 4 is engaged with the inside of the assembly mechanism 8 to complete the fixation.

Before welding, the pillow block 4, the traction beam 5 and the coupler seat 6 are respectively placed on the first-class assembly parts 7041, the second-class assembly parts 7042 and the third-class assembly parts 7043. When the pillow block 4, the traction beam 5 and the coupler seat 6 are pushed to move along the surfaces of the first-class assembly parts 7041, the second-class assembly parts 7042 and the third-class assembly parts 7043, they will be squeezed by the first-class guide parts 70413, the second-class guide parts 70423 and the third-class guide parts 70433, so as to move and align together.

[0048] The slowly rotating first-class conveyor belt 701, second-class conveyor belt 702 and third-class conveyor belt 703 will convey the bolster beam 4, traction beam 5 and coupler seat 6 toward the direction of the turning mechanism 9 until the bolster beam 4, traction beam 5 and coupler seat 6 move to the side of the turning mechanism 9. At this time, the conveying mechanism 7 stops running, and the started electric push rod 902 will extend the output shaft outward to drive the hydraulic clamp 903 to move. At the same time, the hydraulic clamp 903 will synchronously start clamping and push the coupler seat 6 (using an external pump through the hydraulic pipe 903). 3, hydraulic oil is introduced into the interior of the clamping platform 9031, thereby pushing the clamping claw 9032 to flip and clamp on the coupler seat 6), causing the coupler seat 6 to slide along the top of the third-type assembly part 7043 through the second port 804 and squeeze and push the traction beam 5, causing the traction beam 5 to slide along the top of the second-type assembly part 7042 through the first port 803 and squeeze and push the bolster 4, causing the bolster 4 to slide along the top of the first-type assembly part 7041 and drive the reinforcing rib 401 to engage into the interior of the clamping port 805 (the reinforcing rib 401 is engaged with the reinforcing rib 401). 01 main body is inserted into the interior of the card sleeve 9051, and the ribs of the reinforcing rib 401 are inserted into the interior of the comb groove 9052 to form a snap fit), and at the same time, they are snapped into the interior of the card connector 905 to complete the mutual assembly of the bolster beam 4, the traction beam 5 and the coupler seat 6. At this time, the welding arm 3 starts to operate and welds the joints of the mutually assembled bolster beam 4, the traction beam 5 and the coupler seat 6. After the preliminary welding is completed, the connecting part 901 is started, and the preliminary welding is completed by lifting the electric push rod 902 and the first motor 904. After welding, the bolster beam 4, traction beam 5 and coupler seat 6 are lifted synchronously, and the bolster beam 4, traction beam 5 and coupler seat 6 are suspended. At this time, the first motor 904 is started, driving the bolster beam 4, traction beam 5 and coupler seat 6 to rotate, and at the same time the welding arm 3 runs again to fill the unwelded gap; and during the operation, the friction between the output end of the electric push rod 902 and the hydraulic clamp 903 is increased by the damping member 907. The damping member 907 is a damping bearing to prevent the hydraulic clamp 903 from turning over due to its own weight.

[0049] Reference Figures 1 to 7 In a preferred embodiment, the connecting portion 901 includes a kit 9011 that is sleeved on the outside of the electric push rod 902 and the first motor 904, and a hydraulic connecting rod 9012 is fixedly installed at the bottom of the kit 9011.

[0050] The hydraulic connecting rod 9012 is started and extended outward, and at the same time, the electric push rod 902 and the first motor 904 are lifted through the kit 9011 to drive the sleeper beam 4, the traction beam 5 and the coupler seat 6 that have completed the preliminary welding to be lifted synchronously. During this process, the auxiliary rod 9013 will be extended synchronously.

[0051] Reference Figure 1 to Figure 2 , Figure 4 , Figure 6 to Figure 7 , Fig.10 In a preferred embodiment, the auxiliary part 906 includes a base 9061 fixedly mounted on the top of the second partition 802, two rotating rods 9062 are rotatably mounted on the top of the base 9061, and the tops of the rotating rods 9062 are rotatably connected to a support plate 9063, and a second motor 9064 is mounted on the top of the base 9061, and the output end of the second motor 9064 is fixedly connected to the outer side of a rotating rod 9062.

[0052] When the first motor 904 is started, the bolster 4, the traction beam 5 and the coupler seat 6 are rotated (the rotation angle is 180 degrees), during this process, the second motor 9064 is started synchronously, driving the rotating rod 9062 to rotate synchronously, and at the same time, the supporting plate 9063 is lifted by the rotating rod 9062, so that the supporting plate 9063 supports the flipped coupler seat 6; the specific state is as follows Figure 7 shown.

[0053] Working principle: When in use, the operator starts the whole equipment, and hoists the bolster 4, traction beam 5 and coupler seat 6 to the top of the machine platform 1 in sequence through the external hoisting equipment, so that the bolster 4 is placed in the first type of conveyor belt 701 through the first type of assembly parts 7041, the traction beam 5 is placed in the second type of conveyor belt 702 through the second type of assembly parts 7042, and the coupler seat 6 is placed inside the third type of conveyor belt 703 through the third type of assembly parts 7043. The slowly rotating first type of conveyor belt 701, second type of conveyor belt 702 and third type of conveyor belt 703 will transport the bolster 4, traction beam 5 and coupler seat 6 toward the direction of the turning mechanism 9. In this process, the two sides of the bolster 4, traction beam 5 and coupler seat 6 will be blocked by the first partition plate 801, the second partition plate 802 and the machine platform 1 until the bolster 4, traction beam 5 and coupler seat 6 move to the side of the turning mechanism 9. At this time, the conveying mechanism 7 stops running, and the started electric push rod 902 will extend the output shaft outward. , driving the hydraulic clamp 903 to move, and at the same time, the pump introduces hydraulic oil into the interior of the clamping platform 9031 through the hydraulic pipe 9033, thereby pushing the clamping claw 9032 to flip and clamp on the coupler seat 6, and pushing the coupler seat 6 through the electric push rod 902, causing the coupler seat 6 to slide along the third type shaft roller 70434 at the top of the third type assembly part 7043, and pass through the second port 804 and squeeze and push the traction beam 5, causing the traction beam 5 to slide along the top of the second type assembly part 7042 The second type of shaft roller 70424 slides and passes through the first port 803 and squeezes and pushes the bolster 4, causing the bolster 4 to slide along the first type of shaft roller 70414 on the top of the first type of assembly part 7041 and drive the reinforcing rib 401 to snap into the inside of the snap-in port 805. At the same time, the ribs of the reinforcing rib 401 will also snap into the comb groove 9052 of the snap-in part 905, completing the mutual assembly of the bolster 4, the traction beam 5 and the coupler seat 6, and then fixing them with bolts. The specific state is as follows: Figure 6 As shown; at this time, the welding arm 3 starts to operate, and the joints of the mutually assembled bolster beam 4, traction beam 5 and coupler seat 6 are welded. After the preliminary welding is completed, they are cooled, and then the hydraulic connecting rod 9012 is started, and the bolster beam 4, traction beam 5 and coupler seat 6 after the preliminary welding are driven to be lifted synchronously by lifting the electric push rod 902 and the first motor 904, and the bolster beam 4, traction beam 5 and coupler seat 6 are suspended. At this time, the first motor 904 is started, driving the bolster beam 4, traction beam 5 and coupler seat 6 to rotate 180 degrees. During this process, the second motor 9064 will be started synchronously, driving the rotating rod 9062 to rotate synchronously, and at the same time, the supporting plate 9063 is lifted by the rotating rod 9062 to be located below the coupler seat 6, and then the hydraulic connecting rod 9012 is lowered, so that the supporting plate 9063 supports the flipped coupler seat 6, and after the bolster beam 4 is flipped, its lower end will be re-supported on the surface of the first type of assembly part 7041 to ensure the overall welding stability after flipping. The specific state is as shown in FIG. Figure 7As shown, at the same time, the welding arm 3 runs again to fill the unwelded gaps. After completing the welding of the pillow block 4, the traction beam 5 and the coupler seat 6, the flip mechanism 9 flips the three again by 180 degrees, and replaces the welded pillow block 4, the traction beam 5 and the coupler seat 6 on the top of the machine table 1. Finally, the electric push rod 902 retracts, and the traction pillow buffer assembly is reset. With the re-operation of the conveying mechanism 7, the finished traction pillow buffer is conveyed away, and this reciprocating process is completed to complete the continuous operation.
