Problems solved by technology

[0003] Usually the mass of a load-bearing spring is more than 10kg, and the load-bearing spring is only picked and placed by workers, which makes the workers' daily work intensity very high
And in the process of moving, due to repeated labor, narrow operating space, and heavy weight of the load-bearing spring, workers are prone to hand slipping and loss of force, resulting in injury accidents during the dismantling of the load-bearing spring.

Embodiment 1

[0053] Such as Figure 1 to Figure 3 As shown, a bogie dismantling tool includes a tool frame 1 and a clamping device installed on the tool frame 1, and the clamping device includes a pull rod assembly 2 and a support member 4;

[0054] The tie rod assembly 2 includes a tie rod body 21, which is a cantilever beam-like structure protruding from the tool frame 1, and is also installed on the free end of the tie rod body 21 for applying tension to parts on the bogie. grabbing mechanism;

[0055] The pull rod body 21 is a telescopic rod that is telescopic relative to the tool frame 1;

[0056] The grasping mechanism includes a rotating shaft 23 and a gear lever 24 connected to the rotating shaft 23, one end of the gear lever 24 is fixed on the side of the rotating shaft 23;

[0057]Described rotating shaft 23 is hinged on the pull rod body 21, and the free end of described pull rod body 21 is also provided with flanging 22, and described rotating shaft 23 is adjacent to flanging...

Embodiment 2

[0066] Such as Figure 1 to Figure 3 As shown, this embodiment is further limited on the basis of Embodiment 1: as a specific implementation form of the support member 4, it is set as follows: the support member 4 includes two cantilever rods 41 protruding from the tool frame 1, and also includes a pocket Body 42, the pocket body 42 is a flexible material, one end of the pocket body 42 is fixed on one of the cantilever bars 41, and the other end of the pocket body 42 is fixed on another cantilever bar 41;

[0067] The middle part of the pocket body 42 falls down to form a pocket-shaped space for constraining the parts on the support member 4;

[0068] The supporting member 4 also includes a third driving mechanism, which is used to change the distance between the two cantilever rods 41 ;

[0069] The grabbing mechanism is located directly above the pocket-shaped space. In this solution, the pull rod assembly 2 provides pulling force for the spring to fall. Under the above pu...

Embodiment 3

[0086] This embodiment provides a bogie dismantling method, using the bogie dismantling tool provided by any one of the above embodiments to disassemble the parts on the bogie, the parts include load springs and Shock springs, including the following steps in sequence:

[0087] S1. Drive the pull rod body 21 so that the pull rod body 21 extends into the gap above the part. When the shift rod 24 contacts the part, the shift rod 24 rotates around the rotating shaft 23 so that the pull rod body 21 can continue to extend in;

[0088] When the free end of the gear lever 24 enters the central area of ​​the part, the gear lever 24 drives the rotating shaft 23 to reverse automatically under gravity;

[0089] S2. Drive the pull rod body 21 back. When the gear rod 24 acts on the surface of the part, the folded edge 22 hinders the further rotation of the gear rod 24. At this time, the gear rod 24 applies a pulling force to the part, so that the part is dumped on said support surface;

Abstract

The invention discloses a tool for steering disassembly and a bogie disassembling method. The tool comprises a tool frame and a clamping device. The clamping device comprises a pulling rod assembly and a supporting part. The pulling rod assembly comprises a pulling rod body. A grabbing mechanism is further installed on the pulling rod body. The pulling rod body is a telescopic rod. The grabbing mechanism comprises a rotating shaft and a stop rod. The rotating shaft is hinged to the pulling rod body. A folding edge is further arranged at the free end of the pulling rod body. The stop rod can rotate to be parallel to the pulling rod body. The supporting part is located under the pulling rod body. The method is the using method of the tool. By the adoption of the tool and the disassembling method in the scheme, the fault rate in the disassembling process of a bogie can be effectively reduced, and meanwhile, the tool and the method have the characteristics that the speed of completing matching with parts on the bogie and removing matching is high.

Description

technical field [0001] The invention relates to the technical field of bogie dismantling equipment, in particular to a steering dismantling tool and a bogie dismantling method. Background technique [0002] The bogie is one of the important components in the structure of the rail vehicle, and various parameters of the bogie also directly determine the stability of the vehicle and the ride comfort of the vehicle. In the process of overhauling the bogie, the structure needs to be disassembled. The bogie includes load-bearing springs. The load-bearing springs are mainly removed by manual movement. The load-bearing springs at both ends of the bogie are divided into three rows: outer, middle, and inner. Bogies with different models have differences in the number and type of load springs, and the pitch of the load springs is also different. A load spring includes an inner load spring and an outer load spring, and the distance between the inner load spring and the outer load spring...
