Description
Technical Field
[0001] This utility model belongs to the technical field of yard bridge trolleys, specifically relating to a yard bridge trolley running mechanism arrangement device. Background Technology
[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] During the operation of the yard crane, the yard crane trolley is mainly responsible for carrying the spreader and the container, and making horizontal reciprocating movements along the main beam track of the yard crane to realize the lateral handling of the container between different positions in the yard. It can precisely control the parking position to ensure that the spreader is accurately aligned with the container, so as to achieve efficient and accurate loading and unloading operations.
[0004] Currently, the general procedure for horizontally arranged trolley running mechanisms in yard bridges is to first install the trolley wheels, and then, using the trolley wheels as a reference, sequentially install the reducer, motor, and brake. The specific operation involves leveling the trolley frame, installing the trolley wheels, and adjusting key data such as level, track gauge, and skewness to ensure they are within acceptable limits. Using the wheel axles as a reference, the reducer output shaft and support positioning are adjusted using a dial indicator. Then, using the reducer input shaft as a reference, the motor output shaft and support positioning are adjusted using a dial indicator. After the brake disc coupling is secure, the brake and support positioning are adjusted. After all positioning checks are passed, the supports are welded, and the paint is repaired. While this method is widely used in industrial settings, it has the following drawbacks: the production cycle of purchased components such as reducers, motors, and brakes is relatively long; the trolley frame structure needs to be fabricated, machined, and painted before the trolley running mechanism can be installed; and support welding damages the paint, affecting product appearance quality, increasing production time, and material and labor costs. Utility Model Content

The reducer support positioning plate, the brake support positioning plate, and the motor support positioning plate are sequentially installed on the supporting steel pipe.
[0008] As a further technical solution, the wheel hole positioning device includes an end circular plate and an inner positioning plate, wherein the end circular plate is installed at the other end of the supporting steel pipe.
[0009] As a further technical solution, the inner positioning plate is installed on the supporting steel pipe, and the inner positioning plate is located on one side of the end circular plate.
[0010] As a further technical solution, the end sealing plate, the end circular plate, the inner positioning plate, and the supporting steel pipe are fixedly connected.

[0018] The reducer support positioning plate, motor support positioning plate, and brake support positioning plate of this utility model are respectively assembled and fixed to the reducer, motor support, and brake support. They are then hoisted together with a crane using lifting lugs, and assembled with the trolley frame. A wheel hole positioning device replaces the wheel and assembles with the trolley frame wheel holes, positioning all supporting components at once, thus replacing the reducer, motor, and brake. The supporting components are welded before the trolley frame structure is painted, improving assembly efficiency.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0025] Currently, the general procedure for horizontally arranged trolley running mechanisms in yard bridges is to first install the trolley wheels, and then, using the trolley wheels as a reference, sequentially install the reducer, motor, and brake. The specific operation involves leveling the trolley frame, installing the trolley wheels, and adjusting key data such as level, track gauge, and skewness to ensure they are within acceptable limits. Using the wheel axles as a reference, the reducer output shaft and support positioning are adjusted using a dial indicator. Then, using the reducer input shaft as a reference, the motor output shaft and support positioning are adjusted using a dial indicator. After the brake disc coupling is secure, the brake and support positioning are adjusted. After all positioning checks are passed, the supports are welded, and the paint is repaired. While this method is widely used in industrial settings, it has the following drawbacks: the production cycle of purchased components such as reducers, motors, and brakes is relatively long; the trolley frame structure needs to be fabricated, machined, and painted before the trolley running mechanism can be installed; and support welding damages the paint, affecting product appearance quality, increasing production time, and material and labor costs.
[0026] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a trolley running mechanism arrangement device, such as... Figure 1As shown, it includes a main shaft 1, a wheel hole positioning device 2, a reducer support positioning plate 3, a motor support positioning plate 4, and a brake support positioning plate 5; the wheel hole positioning device 2 is installed on the main shaft 1; the main shaft 1 includes a support steel pipe 11, lifting lugs and an end sealing plate 13, the lifting lugs are installed at both ends of the upper part of the support steel pipe 11, and the end sealing plate 13 is installed at one end of the support steel pipe 11; the reducer support positioning plate 3, the brake support positioning plate 5 and the motor support positioning plate 4 are sequentially installed on the support steel pipe 11.
[0027] The reducer support positioning plate 3, motor support positioning plate 4, and brake support positioning plate 5 are respectively assembled and fixed to the reducer, motor support 8, and brake support 7. They are then hoisted together with the trolley frame using the lifting lug 12 and a crane. The wheel hole positioning device 2 replaces the wheels and assembles with the trolley frame wheel holes, positioning all supporting components at once. This replaces the reducer, motor, and brake. The supporting components are welded before the trolley frame structure is painted, improving assembly efficiency. After the reducer, motor, and brake return to the factory, the supports are directly and precisely positioned, significantly shortening the trolley running mechanism assembly time. This not only improves assembly efficiency but also reduces material and labor costs, providing strong assurance for product quality and timeliness.
[0028] The wheel hole positioning device 2 includes an end circular plate 21 and an inner positioning plate 22. The end circular plate 21 is installed at the other end of the supporting steel pipe 11. The inner positioning plate 22 is installed on the supporting steel pipe 11 and is located on one side of the end circular plate 21. The end sealing plate 13, the end circular plate 21, and the inner positioning plate 22 are fixedly connected to the supporting steel pipe 11.

[0030] The reducer support positioning plate 3 and the support steel pipe 11 are fixedly connected, the motor support positioning plate 4 and the support steel pipe 11 are fixedly connected, and the brake support positioning plate 5 and the support steel pipe 11 are fixedly connected.
[0031] Specifically, the supporting steel pipe 11 serves as a support and installation tool, supporting the reducer support positioning plate 3, the motor support positioning plate 4, and the brake support positioning plate 5. The reducer support 6 is installed through the reducer support positioning plate 3, the motor support 8 is installed through the motor support positioning plate 4, and the brake support 7 is installed through the brake support positioning plate 5, thereby ensuring the accurate installation position of the reducer, motor, and brake.
[0032] like Figure 2 As shown, the reducer support positioning plate 3 has threaded holes, and the reducer support positioning plate 3 and the reducer support 6 are connected by bolts. The motor support positioning plate 4 has threaded holes, and the motor support positioning plate 4 and the motor support 8 are connected by bolts. The brake support positioning plate 5 has threaded holes, and the brake support positioning plate 5 and the brake support 7 are connected by bolts. The reducer is installed on the reducer support 6, the motor is installed on the motor support 8, and the brake is installed on the brake support 7.
[0033] Specifically, the reducer, brake, and motor are connected to their corresponding supports using bolts. The bolted connections are secured by the engagement of nuts and bolts. Disassembly is simple: just unscrew the nuts without damaging the connections, facilitating equipment maintenance, parts replacement, or reassembly. The connections are reliable; when correctly installed and used, bolted connections provide stable tightening force and can withstand significant loads.
[0034] like Figure 3 As shown, the lifting lug 12 and the supporting steel pipe 11 are fixedly connected.
[0035] Specifically, the lifting lugs 12 are symmetrically arranged on the supporting steel pipe 11. By connecting the crane hook and the lifting lugs 12, the device can be lifted. The symmetrical arrangement of the lifting lugs 12 ensures the balance of the lifting and effectively avoids tilting during the lifting process.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
