Abstract
Description
Technical Field
[0001] This utility model relates to the field of coke oven vehicles, and in particular to a fireproof device for the driver's cab of a coke oven vehicle. Background Technology
[0002] Coke ovens typically operate under negative pressure, containing burning coal gas. If the power supply to the coke oven suddenly fails, the loss of negative pressure inside the furnace causes flames to erupt, directly hitting the driver's cab window and posing a significant danger to equipment and personnel. This necessitates a device that detects power outages and can immediately activate to protect the driver's cab and personnel.
[0003] In the coke oven operating environment, the main method of protecting the driver's cab currently relies on the common fire protection facilities installed inside, such as conventional fireproof glass and some basic heat insulation materials. These facilities can block the intrusion of external heat and flames to a certain extent, protecting the equipment and personnel inside the driver's cab from direct high-temperature damage.
[0004] However, existing protection methods have significant shortcomings. When the coke oven power supply system suddenly fails, the negative pressure inside the furnace is lost, and flames will instantly erupt and directly hit the driver's cab window. At this time, conventional fire prevention facilities alone cannot quickly and effectively block the impact of the flames, which may damage the equipment and pose a significant threat to the safety of production personnel. This lag and limited protective effect make it difficult for existing methods to meet the reliable protection requirements of the driver's cab in coke oven operation scenarios. There is an urgent need for a fire prevention device that can respond promptly and efficiently to situations where flames erupt due to sudden power outages in coke ovens. Utility Model Content
[0005] This utility model provides a fire prevention device for the driver's cab of a coke oven vehicle, which solves the problem that existing fire prevention devices cannot quickly and effectively block the impact of flames.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A fireproof device for the driver's cab of a coke oven vehicle includes: a drive unit, a baffle, and a pulley;
[0008] The pulley is positioned above the drive device and the baffle, and is fixed to the top plate; the drive device is connected to one end of a connecting rope, the middle of the connecting rope passes through the pulley, the other end of the connecting rope is connected to the upper surface of the baffle, and one end of the baffle is rotatably connected to a rotating shaft;
[0009] When the baffle is placed horizontally, a first limiting block is provided above the upper surface of the baffle; when the baffle is placed vertically, a second limiting block is provided on the left side of the left surface of the baffle.
[0010] Furthermore, the drive unit, baffle, and pulley are located above the driver's cab, the furnace is located to the right of the baffle, and the rotating shaft is located to the right of the driver's cab.
[0011] Furthermore, the connecting rope is a steel wire rope.
[0012] Furthermore, the center of the drive device is on the same horizontal line as the axis of rotation.
[0013] Furthermore, the rotating shaft is located at one end of the baffle near the drive device.
[0014] Furthermore, with the vertical center line of the pulley as the vertical axis, the drive device and the rotating shaft are on the left side of the vertical axis, and the connection point between the baffle and the connecting rope is on the right side of the vertical axis.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention features an automatic baffle deployment and retraction capability with reliable operation. During a power outage, the winch motor drives the baffle to lower using continuous power supply and the switching of contactor contact states. When power is restored, the system automatically switches states, retracting the baffle to its original position. The entire process requires no manual intervention, avoiding potential safety hazards and efficiency issues associated with manual operation. Furthermore, the precise coordination of the limit device ensures accurate stopping of the machine during both lowering and retraction, preventing damage to the equipment from excessive movement and guaranteeing long-term stable and reliable operation.
[0017] Traditional protective devices may have high requirements for a continuous and stable power supply to coke oven vehicles; a power outage could cause the protective function to fail. This device introduces an uninterruptible power supply (UPS), ensuring that the winch motor continues to receive power to drive the baffle in the event of a power outage. This reduces the overall protective system's dependence on power continuity, enhances emergency response capabilities, improves adaptability to complex operating conditions, and reduces the risk of accidents caused by power failures, providing a more solid guarantee for the safe production of coke oven vehicles.
[0018] This invention improves the driver's cab's safety system, enabling it to react autonomously to sudden power outages and other abnormal situations. This not only enhances the safety performance of the driver's cab itself but also further optimizes the automation level of coke oven vehicles, allowing them to operate more efficiently and safely in the complex coke oven working environment. This aligns with the trend of modern industrial equipment moving towards automation and intelligence, and helps improve the overall efficiency and safety of coke oven production.

[0030] This utility model provides a technical solution: a fireproof device for the driver's cab of a coke oven vehicle, such as... Figure 1 As shown, it includes: a drive unit 1, a baffle 2, and a pulley 3;
[0031] The pulley 3 is positioned above the drive device 1 and the baffle 2, and is fixed to the top plate. The drive device 1 is connected to one end of a connecting rope, the middle of which passes through the pulley 3, and the other end of which is connected to the upper surface of the baffle 2. The connecting rope is a steel wire rope. One end of the baffle 2 is rotatably connected to a rotating shaft 4. The drive device 1, baffle 2, and pulley 3 are positioned above the driver's cab 7, with the furnace located to the right of the baffle 2 and the rotating shaft 4 located to the right of the driver's cab 7. The center of the drive device 1 and the axis of the rotating shaft 4 are on the same horizontal line.
