[0002] In the maintenance and repair of AC electric locomotives, the windshield is a crucial component, typically employing electrically heated glass to meet specific functional requirements. According to relevant regulations, if the windshield exhibits poor heating, cracks, or scratches affecting visibility due to external factors during the locomotive's commissioning phase, it must be replaced. However, in practice, without specialized tooling, replacing the glass often requires re-erecting the locomotive and performing the work on an assembly platform. This not only leads to rework of a series of procedures, including unloading, low-voltage commissioning, high-voltage commissioning, and trial operation, but also significantly increases maintenance costs and time.

[0003] Currently, traditional tooling presents numerous inconveniences in its use. For example, operators must first move the glass from the ground onto the tooling, and then from the tooling to the locomotive's front window for installation. This process is not only inefficient but also consumes a significant amount of manpower, severely impacting the overall efficiency of locomotive maintenance. Utility Model Content

[0019] Example 1

[0020] Please refer to Figure 1-3This utility model provides a support fixture for the installation of locomotive windshield glass 10 without the need for a lifting vehicle. It is a specialized device designed to solve the problems of reliance on lifting vehicles, cumbersome operation, and low efficiency in the traditional locomotive windshield glass 10 installation process. Its core structure includes a support frame 1, which serves as the overall load-bearing foundation. This support frame 1 is made of high-strength steel and welded into a frame structure, possessing sufficient load-bearing capacity to support the weight of the glass 10, the operators, and various functional components. It also incorporates a lightweight design for easy and flexible movement.

[0021] A precision handling mechanism 2 is fixedly installed on the top of the bracket 1. This mechanism is the core execution component that enables the glass 10 to be accurately transferred from the storage position to the locomotive front window installation position. Through multi-dimensional motion adjustment, it can smoothly and safely transport the glass 10 to be installed to the corresponding installation position of the locomotive front window, and can achieve fine position adjustment to ensure the precise alignment of the glass 10 with the installation benchmark, greatly reducing the labor intensity and operation difficulty of manual handling.

[0022] To ensure the tooling can move flexibly within the work area, two drive wheels 3 and two casters 4 are installed at the four corners of the bottom of the support 1. The drive wheels 3 are made of large-diameter wear-resistant rubber wheels with built-in high-power DC drive motors, which can provide sufficient driving force, enabling the tooling to move smoothly on various complex road surfaces such as workshop floors and railway tracks. The casters 4 are heavy-duty casters with braking function, which can not only work with the drive wheels 3 to enable the tooling to turn in any direction, but also lock in place by braking during operation to ensure stable parking of the tooling and prevent displacement during installation.

[0023] A storage battery 5 is fixedly installed inside the bracket 1. The storage battery 5 is a high-capacity lithium iron battery, which has the characteristics of high energy density, many charge and discharge cycles, and strong endurance. It can provide a continuous and stable power supply for all electrical components such as the drive motor of the drive wheel 3, various actuator motors of the conveying mechanism 2, and the electrical control box 6.

[0024] The drive motor of the drive wheel 3, the various actuator motors of the conveying mechanism 2, and the battery 5 are all electrically connected to the electrical control box 6 fixed on one side of the top of the bracket 1 via wires. The electrical control box 6 integrates components such as a microprocessor, relays, contactors, operation buttons, and a display screen, forming a complete control system. Operators can control the start, stop, direction, and speed of the drive wheel 3 via the operation panel on the electrical control box 6 or a handheld remote control to move the tooling; simultaneously, it can precisely control various actions of the conveying mechanism 2 to complete operations such as lifting, translating, and rotating the glass 10. The electrical control box 6 also has a status monitoring function, which can display information such as the battery level of the battery 5 and the working status of each motor in real time, allowing operators to promptly grasp the equipment's operating status and ensure smooth operation.

[0025] The conveying mechanism 2 includes a support rod 201 fixedly mounted on the top of the bracket 1. The support rod 201 is made of high-strength alloy and is vertically fixed to the top of the bracket 1 by welding or bolting, providing a stable support foundation for subsequent components. A bearing plate 202, perpendicular to the support rod 201, is rotatably mounted on its top via a high-precision rotary bearing. The rotary bearing has low friction and high load-bearing capacity, ensuring that the bearing plate 202 can rotate flexibly around the support rod 201, enabling horizontal orientation adjustment.

[0026] A first drive motor 203, a servo motor, is fixedly mounted on the top of the support plate 202 near the support rod 201 via bolts. The drive shaft of the first drive motor 203 is fixedly connected to a lead screw 205 that passes through and is threaded onto the moving plate 204 via a coupling. The free end of the lead screw 205 is rotatably connected to the support plate 202 via a high-precision bearing seat 206. The ball bearings within the bearing seat 206 effectively reduce frictional resistance during the rotation of the lead screw 205, ensuring smooth transmission. A limiting rod 207, fixedly connected to the support plate 202, is provided on one side of the lead screw 205. The limiting rod 207 is a high-strength optical shaft that passes through and slides on the moving plate 204. The presence of the limiting rod 207 restricts the moving plate 204 to linear movement only along the axial direction of the lead screw 205, preventing the moving plate 204 from rotating with the lead screw 205 and ensuring the stability and accuracy of the transmission.

[0027] A winch 208 is bolted to the movable plate 204. The winch 208 is an electric winch with stable rope winding and unwinding performance. A first rope 209 is wound on the drive shaft of the winch 208. The first rope 209 is a high-strength, low-elongation special steel wire rope. The free end of the first rope 209 passes through a long through hole 2021 provided on the bearing plate 202. The long through hole 2021 is opened along the length direction of the bearing plate 202 to provide guidance and movement space for the movement of the first rope 209. The free end of the first rope 209 is finally connected to the clamping assembly 7 for fixing and clamping the glass 10 to be installed. By winding and unwinding the first rope 209 by the winch 208, the glass 10 can be lifted and transported vertically. With the rotation of the bearing plate 202 and the horizontal movement of the movable plate 204, the position of the glass 10 in three-dimensional space can be adjusted, and the glass 10 can be accurately transported to the front window of the locomotive.

[0028] Example 2

[0029] like Figure 1-3As shown, the conveying mechanism 2, in addition to achieving the horizontal orientation adjustment of the glass 10, also incorporates a precise rotation drive assembly. Specifically, this includes a second drive motor 210 fixedly mounted on the bottom of the support plate 202 near the support rod 201. This motor is a high-torque servo motor, rigidly connected to the bottom of the support plate 202 via bolts through a customized motor bracket 1, ensuring stability during power output. The drive shaft of the second drive motor 210 is fitted with a high-precision gear 211 via a keyed connection structure. This gear is made of high-strength alloy material and precision-machined, with hardened tooth surfaces to improve wear resistance and transmission accuracy.

[0030] In conjunction with this, a gear ring 212 that meshes with the gear 211 is fixedly fitted at the corresponding height position of the support rod 201. The gear ring 212 is also made of high-strength steel. Its inner ring is fixed to the outer wall of the support rod 201 by interference fit or bolt connection, and the outer ring is machined with gear teeth that are perfectly matched with the gear 211 to form a precision gear transmission pair.

[0031] When the horizontal angle of the support plate 202 needs to be adjusted, the second drive motor 210 starts upon receiving a command from the control box 6. Its output torque is transmitted to the gear 211 via the drive shaft. The meshing action of the gear 211 and the gear ring 212 converts the rotational motion of the motor into the circumferential rotation of the support plate 202 around the support rod 201. This gear 211 transmission method not only enables the support plate 202 to rotate 360 ​​degrees, but also allows for fine-tuning of the angle through precise control of the servo motor. The minimum adjustment accuracy can reach 0.5 degrees, ensuring that the glass 10 can be accurately aligned with the installation position of the locomotive's front window. At the same time, the meshing transmission of the gear 211 and the gear ring 212 has a self-locking function, which maintains the current angular position of the support plate 202 when the motor stops working, preventing displacement due to external forces and ensuring the stability and safety of the glass 10 during transportation.

[0032] Example 3

[0033] As shown in 1-4, the clamping assembly 7 includes two symmetrical fixing frames. This symmetry creates a balanced clamping force from both sides of the glass 10, preventing excessive force at a single point from damaging the glass 10. Each fixing frame includes a vertically arranged first angle steel 701, which is made of high-strength rolled steel and has good bending resistance and structural stability. The first angle steel 701 has a right-angled cross-section, with one right-angled side serving as the contact surface with the side of the glass 10. The surface is finely polished and covered with a layer of soft rubber cushioning pad, which increases the friction between the angle steel and the glass 10 to prevent slippage and avoids direct metal contact that could scratch the surface of the glass 10.

[0034] The top and bottom ends of the first angle steel 701 are both fixedly provided with second angle steels 702 extending in the horizontal direction by welding, and the two second angle steels 702 are both located on the same side of the first angle steel 701, jointly forming a three-dimensional frame structure similar to a "C" shape with the first angle steel 701. The second angle steel 702 is also made of high-strength steel, and its extending direction is perpendicular to the vertical direction of the first angle steel 701, forming the support and limit for the upper and lower edges of the glass 10.

[0035] To achieve the adaptability of the clamping assembly 7 to glasses 10 of different sizes, a bidirectional threaded rod 703 is rotatably connected between two second angle steels 702 located in the same horizontal direction (i.e., the top and the bottom), and the distance between the two second angle steels 702 is adjusted by rotating the bidirectional threaded rod 703. Specifically: a convex block with a preset threaded hole is welded to the vertical side wall of the second angle steel 702 on the side背离 the glass 10, and the two ends of the bidirectional threaded rod 703 respectively pass through the convex blocks with preset threaded holes on the corresponding side second angle steels 702 to form a threaded fit.

[0036] To facilitate the operator to rotate the bidirectional threaded rod 703, a handle is welded to any one end of the bidirectional threaded rod 703, and the operator can directly hold the handle to rotate the bidirectional threaded rod 703. When the bidirectional threaded rod 703 is rotated clockwise, due to the opposite thread directions on both sides, the two second angle steels 702 will move inward along the axial direction of the threaded rod simultaneously, reducing the distance; when rotated counterclockwise, they will move outward synchronously, increasing the distance, realizing the clamping adaptation to glasses 10 of different widths.

[0037] To further enhance the stability of the glass 10 in the clamping assembly 7 and prevent the glass 10 from tilting and shaking in the horizontal direction during handling, a groove 704 perpendicular to the axial direction of the second angle steel 702 is opened on the side wall of the middle and lower part of the first angle steel 701; the groove 704 is formed by milling process, a screw rod 706 is fixedly arranged in the groove 704, the screw rod 706 is made of high-strength stainless steel and has good corrosion resistance, a nut 707 is threadedly connected to the screw rod 706, and a limiting block 708 with a clearance fit with the screw rod 706 is arranged between the nut 707 and the bottom of the groove 704, and the limiting block 708 is made of wear-resistant engineering plastic or soft metal.

[0038] The operator can adjust the position of the limiting block 708 by rotating the nut 707: when rotating the nut 707 clockwise, the nut 707 moves along the screw 706 toward the bottom of the groove 704, pushing the limiting block 708 to move closer to the bottom of the groove 704 until the limiting block 708 is tightly fitted with the side of the glass 10, firmly fixing the glass 10 in the clamping assembly 7, preventing the glass 10 from falling off due to vibration or tilting during transportation; when it is necessary to remove the glass 10, simply rotate the nut 707 counterclockwise, the nut 707 moves away from the bottom of the groove 704, the limiting block 708 loses its clamping force, and the glass 10 can be easily removed from the clamping assembly 7.

[0039] The two second angle steels 702 located at the top of the first angle steel 701 are both fixedly connected to the free ends of the first rope 209 via second ropes 705. The second rope 705 and the first rope 209 are made of high-strength composite steel wire rope of the same specification. It is made of multiple strands of steel wire twisted together, and its diameter is designed according to the maximum load-bearing capacity of the glass 10. It has the characteristics of tensile strength, wear resistance, and low elastic deformation, ensuring that it will not elongate significantly when bearing the weight of the glass 10, thus ensuring lifting accuracy.

[0040] Example 4

[0041] like Figure 1-2 As shown, a guardrail 8 is provided around the top edge of the support 1 to protect personnel working on top of the support 1 and prevent them from falling due to accidental slips.

[0042] The side of the support 1 is fixed with multiple horizontal bars 9 at equal intervals along the vertical direction. There are four horizontal bars 9. The horizontal bars 9 are fixed to the side of the support 1 by welding. This not only serves as a ladder, making it easy for operators to climb to the top of the support 1, but also increases the stability of the support 1 structure.

[0043] The working process of the supporting fixture: The operator controls the drive wheels 3 and casters 4 through the electrical control box 6 to move the fixture to a suitable position next to the locomotive, so that the transport mechanism 2 is roughly aligned with the installation area of ​​the locomotive's front window. According to the size of the glass 10, the double-threaded rod 703 is rotated to adjust the spacing of the fixing frame to match the width of the glass 10; the glass 10 is snapped into the "U"-shaped structure of the fixing frame, and the nut 707 is tightened to clamp the bottom of the glass 10, thus completing the fixing of the glass 10.

[0044] Start the second drive motor 210, which rotates the bearing plate 202 through the gear 211 and the gear ring 212 to adjust the horizontal position of the glass 10; start the first drive motor 203, which drives the lead screw 205 to rotate, and the moving plate 204 moves horizontally to adjust the horizontal position; start the winch 208, which winds up and unwinds the first rope 209 to adjust the vertical height of the glass 10 so that the glass 10 is precisely aligned with the installation position of the locomotive front window glass 10.

[0045] Workers are protected by the top guardrail 8 of the bracket 1. They manually assist the glass 10 in docking and fixing it with the locomotive front window installation structure (such as bolt connection, rubber strip engagement, etc.). After the installation is completed, the transport mechanism 2 is reversed to release the clamping component 7 and move the tooling away from the work area, thus completing a single installation operation.
