Description

Technical Field

[0001] The utility model belongs to the technical field of coking, and in particular relates to a dry quenching coke tank carrier. Background Art

[0002] The dry coke quenching process is a coke quenching process for cooling red coke. During the dry coke quenching process, the red coke in the coke oven is poured into the coke drum. The coke drum containing the red coke is transported to the dry quenching furnace station by a coke drum carrier. The coke drum is lifted by a hoist and the red coke in the coke drum is poured into the dry quenching furnace for cooling.

[0003] Currently, coke can carriers are generally towed by electric locomotives along the coke quenching track to transport coke cans between the coke oven station and the dry quenching oven station. However, the use of electric locomotives for traction results in a longer overall vehicle body, high production costs for the carrier, and the risk of detachment of the connection structure between the electric locomotive and the coke can carrier, posing certain safety hazards. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a dry quenching coke tank carrier, which changes the driving mode of the carrier platform from traction drive to self-drive, and uses the cooperation of walking wheels and drive motors to drive the carrier platform to move, thereby eliminating the need for electric locomotive traction. The overall structure of the carrier is simpler, the overall length of the carrier is reduced, the production cost is reduced, and the safety hazards of the connection structure between the electric locomotive and the carrier platform are avoided.

[0005] The specific technical solution adopted in this utility model is:

[0006] A dry quenching coke tank carrier comprises a carrier platform for placing the coke tank and a guide frame located on the carrier platform. A rotating motor is also provided on the carrier platform. The output end of the rotating motor is vertically upward and is in transmission cooperation with the bottom of the coke tank. The coke tank moves along the coke quenching track with the help of the carrier vehicle and has the freedom to move back and forth between the coke oven station and the dry quenching oven station. Traveling wheels and a drive motor are also provided at the bottom of the carrier platform. The traveling wheels are in rolling cooperation with the coke quenching track. The traveling wheels rotate with the help of the drive motor and drive the carrier platform to have the freedom to move along the coke quenching track.

[0007] The carrying platform is also provided with a fixed structure, which includes a supporting slide rail and a slip ring. The supporting slide rail is fixedly connected to the guide frame, and a ball is provided between the supporting slide rail and the slip ring. The slip ring forms a sliding fit with the supporting slide rail with the help of the ball. The coke tank is located on the inner ring of the slip ring and is fixedly connected to the slip ring with the help of bolts. The coke tank is limited by the slip ring and has the freedom of rotation.

[0008] The supporting slide rail and the slip ring are both annular structures with an L-shaped cross-section. The vertical portion of the supporting slide rail is fixedly connected to the guide frame, and the transverse portion of the supporting slide rail is connected to the bottom of the vertical portion of the supporting slide rail and extends toward the coke tank side. The transverse portion of the supporting slide rail supports the slip ring and forms a sliding fit with the transverse portion of the slip ring by means of balls, and the vertical portion of the slip ring is fixedly connected to the coke tank by means of bolts.

[0009] Limit blocks are also provided on both sides of the carrying platform, and limit slide rails that slide with the limit blocks are provided on both sides of the quenching track. The carrying platform forms a limit perpendicular to the direction of the quenching track with the help of the limit blocks.

[0010] The guide frame includes two groups of guide columns symmetrically arranged on both sides of the carrying platform. The guide columns are fixedly connected to the carrying platform. The top of the guide columns is a wedge-shaped structure. The guide columns on both sides and the carrying platform together form an installation groove. The upper opening of the installation groove is a trumpet-shaped shape that is wide at the top and narrow at the bottom.

[0011] A load-bearing platform is suspended below the carrying platform by means of a connecting rod. The fixed end of the drive motor is fixed on the load-bearing platform, and the driving end of the drive motor is driven in cooperation with the walking wheel.

[0012] The beneficial effects of the utility model are:

[0013] 1. In the present invention, the driving mode of the carrying platform is changed from traction drive to self-drive, and the carrying platform is driven to move by the cooperation of the walking wheels and the drive motor, so there is no need to set up the traction of the electric locomotive. The overall structure of the carrying vehicle is simpler, the overall length of the carrying vehicle is reduced, the production cost is reduced, and the safety hazards of the connection structure between the electric locomotive and the carrying platform are avoided.

[0014] 2.

First, the guide frame is the limiting structure, which is directly fixedly connected to the carrying platform, and the support rail is fixedly connected to the guide frame. During installation, the coke tank enters the ring formed by the slip ring along the guide frame, and then the slip ring is fixed to the side wall of the coke tank with bolts. Since a ball bearing is provided between the slip ring and the support rail, the slip ring has the freedom of relative rotation relative to the support rail, and due to the restraint of the support rail, the slip ring will not separate from the support rail, thereby playing a limiting role and realizing the rotation and limiting of the coke tank.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] A dry quenching coke tank carrier comprises a carrier platform 1 for placing a coke tank 17 and a guide frame located on the carrier platform 1. The carrier platform 1 is also provided with a rotating motor 2. The output end of the rotating motor 2 is vertically upward and is in transmission cooperation with the bottom of the coke tank 17. The coke tank 17 is moved along the quenching track 3 with the help of the carrier and has the freedom to move back and forth between the coke oven station 4 and the dry quenching oven station 5. The bottom of the carrier platform 1 is also provided with a running wheel 6 and a drive motor 7. The running wheel 6 is in rolling cooperation with the quenching track 3. The running wheel 6 is rotated with the help of the drive motor 7 and drives the carrier platform 1 to have the freedom to move along the quenching track 3.

[0023] Currently, coke can carriers are generally towed by electric locomotives and run along the coke quenching track 3 to transport the coke cans 17 between the coke oven station 4 and the dry quenching oven station 5. However, the use of electric locomotives for traction will result in a longer overall vehicle body, a high manufacturing cost of the carrier, and a risk of detachment of the connection structure between the electric locomotive and the coke can carrier, posing certain safety hazards.

[0024] Therefore, in the present invention, the driving mode of the carrying platform 1 is changed from traction drive to self-drive, and the carrying platform 1 is driven to move by the cooperation of the walking wheels 6 and the drive motor 7, so there is no need to set up the traction of the electric locomotive. The overall structure of the carrying vehicle is simpler, the overall length of the carrying vehicle is reduced, the production cost is reduced, and the safety hazards of the connection structure between the electric locomotive and the carrying platform 1 are avoided.

[0025] When in use, the coke can 17 is first located at the coke oven station 4 to feed red coke. During the feeding process, the coke can 17 is always in a rotating state with the help of the rotating motor 2. The carrier vehicle filled with red coke moves along the coke quenching track 3, and is turned and moved to the dry quenching furnace station 5 with the help of the U-turn turntable 16. Then, the coke can 17 with red coke on the carrier vehicle is lifted by the help of the hoist and enters the dry quenching furnace station 5 for cooling. After the red coke is cooled, the coke can 17 is put back on the carrier vehicle by the hoist, moved to the U-turn turntable 16, turned to the unloading station 18 with the help of the U-turn turntable 16 and moved to the unloading station 18 for unloading.

[0026] The carrying platform 1 is also provided with a fixed structure, which includes a supporting slide rail 8 and a slip ring 9. The supporting slide rail 8 is fixedly connected to the guide frame, and a ball 10 is provided between the supporting slide rail 8 and the slip ring 9. The slip ring 9 forms a sliding fit with the supporting slide rail 8 with the help of the ball 10. The coke tank 17 is located on the inner ring of the slip ring 9 and is fixedly connected to the slip ring 9 with the help of bolts. The coke tank 17 is limited by the slip ring 9 and has the freedom of rotation.

[0027] In order to ensure that the red coke in the coke oven can be evenly distributed in the coke tank 17, the coke tank 17 needs to be in a rotating state at all times during the pouring process. At the same time, in order to prevent the coke tank 17 from falling during transportation, a limiting structure needs to be provided on the transport vehicle. Therefore, in order to realize the rotation and limiting of the coke tank 17, the traditional coke tank 17 transport vehicle usually sets a turntable on the transport platform 1, and then sets the limiting structure on the turntable, and uses the turntable to drive the limiting structure and the coke tank 17 to rotate together.

[0028] However, the above structure is complicated, and the limiting structure is not directly connected to the carrying platform 1, and its stability is poor. In the present invention, the turntable is removed, and the support rail 8 and the slip ring 9 are used to achieve the rotational freedom of the coke tank 17, while ensuring that the limiting structure is directly fixedly connected to the carrying platform 1. First, the guide frame is the limiting structure, and the guide frame is directly fixedly connected to the carrying platform 1, while the support rail 8 is fixedly connected to the guide frame. During installation, the coke tank 17 enters the ring formed by the slip ring 9 along the guide frame, and then the slip ring 9 is fixed to the side wall of the coke tank 17 with bolts. Since a ball 10 is provided between the slip ring 9 and the support rail 8, the slip ring 9 has the freedom of relative rotation relative to the support rail 8, and due to the constraint of the support rail 8, the slip ring 9 will not separate from the support rail 8, thereby playing a limiting role and realizing the rotation and limiting of the coke tank 17.

[0029] The supporting rail 8 and the slip ring 9 are both annular structures with an L-shaped cross-section. The vertical portion of the supporting rail 8 is fixedly connected to the guide frame, and the transverse portion of the supporting rail 8 is connected to the bottom of the vertical portion of the supporting rail 8 and extends toward the coke tank 17. The transverse portion of the supporting rail 8 supports the slip ring 9 and forms a sliding fit with the transverse portion of the slip ring 9 by means of balls 10. The vertical portion of the slip ring 9 is fixedly connected to the coke tank 17 by means of bolts. The L-shaped structure of the supporting rail 8 and the slip ring 9 can reduce the contact area between the two, thereby reducing the friction generated between the two and improving the service life. In addition, due to the large size of the carrier vehicle, the L-shaped supporting rail and the slip ring 9 are easier to align and fit compared to rails with other structures such as grooves, which reduces the difficulty of installation.

[0030] In addition, an anti-wear ring 19 is provided between the longitudinal portion of the support rail 8 and the transverse portion of the slip ring 9 . The anti-wear ring 19 is used to further reduce the friction between the support rail 8 and the slip ring 9 .

[0031] Limiting blocks 11 are also provided on both sides of the carrying platform 1, and limiting slide rails 12 that slide with the limiting blocks 11 are provided on both sides of the quenching track 3. The carrying platform 1 forms a limit perpendicular to the direction of the quenching track 3 with the help of the limiting blocks 11. By setting the limiting blocks 11, the carrying vehicle can be prevented from shaking during movement and move smoothly to prevent the red coke in the coke tank 17 from falling due to the shaking of the carrying vehicle.

[0032] The guide frame includes two sets of guide columns 13 symmetrically arranged on either side of the carrier platform 1. The guide columns 13 are fixedly connected to the carrier platform 1. The tops of the guide columns 13 are wedge-shaped. Together, the guide columns 13 and the carrier platform 1 form a mounting slot. The upper opening of the mounting slot is shaped like a trumpet, wide at the top and narrow at the bottom. This trumpet-shaped structure makes it easier for the coke can 17 to fit into the mounting slot.

[0033] A supporting platform 15 is suspended below the carrying platform 1 by means of a connecting rod 14. The fixed end of the drive motor 7 is fixed to the supporting platform 15. The driving end of the drive motor 7 drives the running wheel 6. The lower surface of the supporting platform is higher than the bottom of the running wheel 6.
