Description

Technical Field

[0001] The utility model relates to a car transfer platform for the maintenance of fixed-rotary coke oven machinery. Background Art

[0002] During the production process of a coke oven, coke oven machinery is required for production operations. The coke oven machinery runs on fixed tracks parallel to the longitudinal direction of the coke oven. Regular maintenance of the coke oven machinery is necessary, and repairs are also required when faults occur. Due to the large size of the coke oven machinery, usually reaching more than ten meters in length and having a large weight, generally weighing hundreds of tons, a car transfer platform is needed to transfer the coke oven machinery to a designated maintenance line or parking line when performing maintenance or replacing a spare car.

[0003] The conventional design of the car transfer platform adopts a translation type car transfer platform, which is arranged in a pit and can move bidirectionally along the direction perpendicular to the running track of the coke oven machinery, transporting the coke oven machinery to different parking lines parallel to the running track of the coke oven machinery. Since the conventional car transfer platform covers an area of dozens of meters as a whole, it occupies a large area, and there are often problems of tight site and difficult layout.

[0004] For example, in the prior art, the publication number is CN201128421Y, and the patent name is "A New Type of Car Transfer Platform". The pit for the movement of the car body needs to be dozens of meters long. The maintenance parking lines can only be vertically arranged in the moving direction of the car body, and the length of each parking line exceeds 20 meters. The overall occupied area is very large, exceeding 1000 square meters, and most old factories undergoing transformation cannot provide such an occupied area. Summary of the Invention

[0005] The purpose of the utility model is to provide a car transfer platform for the maintenance of fixed-rotary coke oven machinery, which saves land occupation, adapts to car transfer platforms in complex sites, and meets the use requirements of newly built, rebuilt, and expanded coke ovens.

[0006] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0007] A car transfer platform for the maintenance of fixed-rotary coke oven machinery includes coke oven machinery tracks, a traveling driving device, a driving wheel, a driven wheel, a slewing bearing, an on-vehicle hoist, and a circular traveling track. The car transfer platform is located at the end of the coke oven machinery track and is arranged in a circular pit. A slewing bearing is arranged at the lower end of the car transfer platform body. The circular traveling track and the slewing bearing are located on the same central axis. Driving wheels and an on-vehicle hoist are arranged at the end of the car transfer platform body. The traveling driving device is used to drive the driving wheels, so that the car transfer platform rotates in the positive and negative directions with the central axis as the center of the circle. The on-vehicle hoist is used to hoist the coke oven machinery.

[0008] A current collector is arranged on the slewing bearing. The current collector is connected to an electric control cabinet and is used to provide a power supply.

[0009] A driven wheel is also arranged at the end of the car transfer platform body. The driven wheel is used for support, and the driven wheel rotates with the car transfer platform and moves on the annular running track.

[0010] It also includes a rain shelter, and a rain shelter is arranged above the car transfer platform body.

[0011] The coke oven machinery includes a motor car, a coke quenching car, and a coke pot carrier car.

[0012] A thrust track and a mechanical locking device are also arranged at the end of the car transfer platform body. The driving wheel is connected to a bracket, and a small wheel is connected to the bracket. The small wheel can roll on the thrust track. The thrust track and the annular running track are arranged perpendicular to each other. The thrust track is arranged above the annular running track. The thrust track is used to prevent the coke oven machinery from shaking when moving up and down the car transfer platform and for thrust and guiding, and the mechanical locking device is used to lock the stopping position of the car transfer platform.

[0013] A slewing bearing is arranged between the slewing support and the car transfer platform body.

[0014] The current collector is a brush type current collector.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The car transfer platform is installed in a circular pit at the end of the coke oven machinery track. By adopting a slewing support, it can rotate in both forward and reverse directions along the track located on the circular circumference in the pit, transport the coke oven machinery to a selected position at any angle with the rotation center as the center of the circle, and connect it to several maintenance stop lines at the selected position. It is locked with a mechanical locking device at the selected position, adapts to complex terrains, the stop lines can pass through roads without affecting road traffic, and saves land occupation;

[0017] 2. Due to the adoption of a slewing support, the car transfer platform rotates at a fixed position, reducing the area of the civil engineering pit, avoiding the situation that the large area of the pit cuts off the road or interferes with the structure, effectively reducing the infrastructure investment, and achieving cost reduction and efficiency increase while meeting the use requirements;

[0018] 3. A fixed rain shelter is arranged on the car transfer platform, and the shielding area can cover the entire pit, effectively preventing the pit from accumulating water, eliminating the need to install a pit drainage pump, reducing equipment investment, reducing equipment maintenance workload, and reducing the labor intensity of workers;

[0019] 4. By using a current collector for power reception at a fixed position, there is no need to provide a flexible cable or a safety sliding contact line along the moving direction of the car transfer platform, simplifying the equipment structure, reducing equipment investment, reducing equipment maintenance workload, reducing the labor intensity of workers, improving the operation safety at the same time, and reducing the risk of electric shock to personnel caused by electric leakage.

The driven wheels 2 are used for support, and the driven wheels 2 rotate with the transfer car platform and move on the circular traveling track 8. The traveling drive device is used to drive the driving wheels 1 so that the transfer car platform rotates in both forward and reverse directions around the central axis on the circular traveling track 8 and is connected to several maintenance stop lines passing through the center of the circle. The transfer car platform is locked tightly at the stop position by a mechanical locking device 10. According to the working conditions, the coke oven machinery 11 to be maintained is transported to different stop lines by cooperating the on-vehicle hoist 6 with a ground fixed pulley device, realizing the maintenance and replacement of the coke oven machinery 11. A rain shelter 5 is provided above the transfer car platform body, which can cover the entire pit and prevent water from accumulating in the pit in rainy and snowy weather.
