Description

Technical Field

[0001] This utility model relates to the field of silicon component disassembly and assembly technology, specifically to an auxiliary device for disassembling and assembling silicon components in a locomotive silicon rectifier. Background Technology

[0002] In the technical operation of disassembling and assembling silicon rectifier components in electric locomotives, especially for the TGZ36 / KTGZ-1 silicon rectifier used in the Shaoshan 3B electric locomotive, the disassembly and assembly of its silicon components faces particular difficulties. These silicon components have significant structural uniqueness: irregular shape, no standard force-bearing handles, and must be horizontally disassembled and assembled into a fixed frame within a height range of 40-120cm above the ground; a single component weighs 30-40KG, each unit contains 10-12 components, and during mid-term maintenance, the disassembly and assembly of four units (totaling 40-48 components) must be completed.

[0003] Currently, there is a lack of effective specialized tooling for the disassembly and assembly of silicon components for this specific locomotive model. Existing first-generation silicon component disassembly and assembly equipment is insufficient in function and cannot adapt to the special structural dimensions and stress requirements of this component, resulting in its near failure in actual operation and forcing the work to rely mainly on manual labor. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides an auxiliary device for disassembling and assembling silicon components in a locomotive silicon rectifier, eliminating safety risks arising from working height, avoiding bumps and damage to silicon components and personnel safety hazards during disassembly and assembly, and reducing the labor intensity during silicon component disassembly and assembly.

[0005] Specifically, this utility model is implemented as follows:

[0006] An auxiliary device for disassembling and assembling silicon components in a locomotive silicon rectifier includes:

[0007] Base;

[0008] A roller support mechanism is provided on the base and configured as a liftable structure; it includes a plurality of rollers. In use, the roller support mechanism docks with the silicon element of the silicon rectifier, and the silicon element of the silicon rectifier contacts the roller and moves out along the roller.

[0009] Furthermore, the base is provided with a scissor fork lifting mechanism, and the roller support mechanism is provided on the scissor fork lifting mechanism.

[0010] Furthermore, the scissor fork lifting mechanism is driven to lift by a hydraulic rod.

[0011] Furthermore, the auxiliary device for removing and installing silicon components in the locomotive silicon rectifier also includes:

[0012] A control box, which contains a controller and a battery, and a control button is provided on the control box. The controller is connected to the control button and the hydraulic rod, and the control button is used to control the hydraulic rod.

[0013] Furthermore, the base is a vehicle structure with universal wheels equipped with brakes at the bottom and a pushcart handle on one side.

[0014] Furthermore, the end of the roller support mechanism away from the trolley handle is an open structure for connecting to the silicon element of the silicon rectifier device.

[0015] Furthermore, the roller support mechanism also includes:

[0016] A drive motor is connected to any one of the rollers to drive the rollers to rotate, and adjacent rollers are connected by a transmission connection.

[0017] Working principle:

[0018] During operation, move the auxiliary device to the silicon rectifier and operate the control button on the control box to drive the hydraulic rod to precisely adjust the upper roller support mechanism to the installation height of the rectifier cabinet (30-130cm continuously adjustable); during the disassembly and assembly of the silicon element, its bottom contacts the roller of the roller support mechanism, so that the 30-40kg silicon element can be moved horizontally with only ≤30N thrust.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The auxiliary device provided by this utility model can provide effective support for silicon components when disassembling and assembling silicon components of the TGZ36 / KTGZ-1 silicon rectifier used in the Shaoshan 3B electric locomotive, greatly reducing the labor intensity of disassembling and assembling silicon components. Moreover, the height of the roller support mechanism is adjustable, and it can be adjusted to different heights according to the actual situation to connect the corresponding silicon components. It can achieve efficient operation with a single component disassembly and assembly time of ≤8 minutes and a total time of ≤6.5 hours for four devices and 48 components, completely solving the problems of height risk, uneven force and strength of the original manual operation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1-4 As shown, this embodiment provides an auxiliary device for disassembling and assembling silicon components in a locomotive silicon rectifier, including: a base 1, a scissor fork lifting mechanism 2 and a roller support mechanism 3. The base 1 is a vehicle body structure, with a push handle 11 on one side and four universal wheels 12 with brakes at the bottom to facilitate the movement of the auxiliary device.

[0033] The control box 4 is placed inside the trolley handle 11. The control box 4 contains a built-in battery and controller. The circuit diagram of the control circuit is shown below. Figure 2 As shown, three-phase power supplies L1, L2, and L3 provide power; disconnecting switch QS is used for main power isolation and switching; fuse FU1 is used for main circuit short-circuit protection; AC contactor KM controls the switching of the main circuit of hydraulic rod 21; thermal relay FR is used for overload protection of hydraulic rod 21; M in the circuit diagram represents hydraulic rod 21; changeover switch S is used for manual / automatic mode switching; control buttons SB1 and SB2 on control box 4 are used for manual stop and start, respectively; intermediate relays KA1 and KA2 transmit and process hydraulic signals.

[0034] The scissor lift mechanism 2 is driven by a hydraulic rod 21. The roller support mechanism 3 is located on top of the scissor lift mechanism 2 and is driven by the scissor lift mechanism 2 to lift and stop at any position within a height range of 30-130cm. The maximum load capacity of the scissor lift mechanism 2 is 500kg, covering the single weight requirement and cumulative load of 30-40kg for the Shaoshan 3B type silicon element. The end of the roller support mechanism 3 away from the trolley handle 11 is open for connecting the silicon element 51 of the silicon rectifier device 5. The roller support mechanism 3 includes a bracket and several rollers 31. The rollers 31 are fixed with rolling bearings, arranged in a single row, and are made of metal. The surface can be provided with anti-slip texture or covered with an anti-slip layer, providing sufficient friction to ensure that the silicon element 51 does not shift during translation.

[0035] Example 2

[0036] Based on Embodiment 1, the roller support mechanism 3 adopts an automatic moving silicon element 51, such as... Figure 5-7 As shown, the roller support mechanism 3 is driven by the motor 32, and the adjacent rollers 31 are connected by transmission. The motor 32 controls the rotation of the rollers 31 to form an automatic conveying mechanism, realizing the automatic movement of the silicon element 51, further reducing manual labor.
