Description

Technical Field

[0001] This utility model belongs to the field of coke oven vehicle technology, specifically relating to a telescopic support device for a coke oven coal support plate. Background Technology

[0002] In the coke oven production process, the coal pallets of the coke oven vehicles play an important role in transporting coal cakes to the coke oven area. The coal pallets need to bear coal cakes weighing about 40 tons, and their stability and structural strength are crucial during their movement.

[0003] Currently, there is a significant problem with existing technologies: when the coal support plate moves towards the coke oven opening during the coal charging process, there is a travel range of approximately 1000mm between the front end of the coal support plate and the coke oven opening. Within this range, the coal support plate is in an unsupported load-bearing state. Since the coal cake carried by the coal support plate is extremely heavy, operating without support for a long time can easily lead to deformation of the coal support plate. Once the coal support plate is deformed, it may be unable to enter the furnace area smoothly, and in severe cases, it may even cause the coal cake to overturn. This will not only affect the normal production process of coke oven coal charging and reduce production efficiency, but also seriously damage the stability and service life of the equipment, increase equipment maintenance costs, and also pose certain safety hazards. In summary, there is an urgent need for a telescopic support device for coke oven coal support plates. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a telescopic support device for a coke oven coal support plate. The telescopic support device is disposed below the coal support plate 100, which is located above a coal loading car on one side of a civil engineering platform 200. The telescopic support device for the coke oven coal support plate includes a bracket 1 disposed on the civil engineering platform 200, a support frame 2 disposed at the top center of the bracket 1, a support platform 3 slidably connected to the support frame 2, and a drive mechanism 4 disposed below the support frame 2. The bracket 1 is a rectangular frame structure, which is fixedly installed on the civil engineering platform 200 by bolts to form a stable foundation support. The support frame 2 is a frame structure perpendicular to the bracket 1, and its bottom is connected to a fixed frame 300 on the top of the coal loading car by bolts. One end of the drive mechanism 4 is fixed to the bracket 1, and the other end is fixedly connected to the bottom of the support platform 3, for driving the support platform 3 to slide along the support frame 2. A fixed frame 300 is installed on the top of the coal loading car. The bottom of the support frame 2 is connected to the top of the fixed frame 300, realizing the fixed connection between the support frame 2 and the coal loading car, ensuring that the support frame 2 can move synchronously with the coal loading car. A guide rail is opened on the inner side of the support platform 3. Slider 21 matching the guide rail is set on both sides of the support frame 2. The slider 21 is slidably connected in the guide rail. The guide rail is set along the length direction of the support platform 3. The slider 21 is embedded in the guide rail, so that the support platform 3 can slide in the vertical direction of the support frame 2, realizing the extension and retraction of the support platform 3. The coal support plate 100 abuts against the top of the support platform 3. The coal support plate 100 abuts against the top of the support platform 3. The support platform 3 supports the weight of the coal support plate 100 and the coal cake. The top surface of the support platform 3 is flat and is used to abut against the coal support plate 100. Its size is slightly larger than the bottom contact area of ​​the coal support plate 100 to ensure that a uniform support force is provided.

[0019] As one specific implementation, in the telescopic support device for coke oven coal support plate of this utility model, the drive mechanism 4 adopts a drive cylinder, which provides a stable driving force through the telescopic action of the cylinder, ensuring that the support platform 3 can move accurately and smoothly.

[0020] As a specific embodiment, in the telescopic support device for a coke oven coal support plate of this utility model, a first liner 5 is provided between the support frame 2 and the coal support plate 100. This arrangement can enhance the contact stability between the support frame 2 and the coal support plate 100 and distribute the load-bearing pressure. More specifically, the first liner 5 is made of wear-resistant rubber or metal plate, which can reduce the friction between the coal support plate 100 and the support platform 3.

[0021] In one specific embodiment, in the telescopic support device for coke oven coal support plate of this utility model, a second liner 6 is provided between the support frame 2 and the bracket 1. This arrangement is used to improve the connection stability between the support frame 2 and the bracket 1 and reduce relative vibration and friction.

[0022] The working principle of the telescopic support device for coke oven coal support plate of this utility model is as follows:

[0023] When the coal charging car has not moved to the coke oven opening, the drive mechanism 4 is in a retracted state, and the support platform 3 is located at the end of the support frame 2 away from the coal support plate 100. At this time, the coal support plate 100 is supported by the coal charging car's own support structure. When the coal charging car moves towards the coke oven opening and the front end of the coal support plate 100 enters the unsupported 1000mm stroke range, the control system starts the drive mechanism 4, the piston rod of the drive cylinder extends, and pushes the support platform 3 to slide along the support frame 2 towards the coal support plate 100. The support platform 3 slides to the bottom of the coal support plate 100 and abuts against it, and together with the coal charging car's own support structure, it bears the weight of the coal support plate 100 and the coal cake, ensuring that the coal support plate 100 is effectively supported in the unsupported range. After the coal support plate 100 transports the coal cake to the furnace area to complete the coal charging, the drive mechanism 4 reverses its action, the piston rod of the drive cylinder retracts, and drives the support platform 3 to slide along the support frame 2 away from the coal support plate 100 back to the initial position. The coal charging car carries the coal support plate 100 back, waiting for the next coal charging operation.

[0024] In summary, compared with the prior art, the telescopic support device for coke oven coal support plates of this utility model has the following advantages and beneficial effects:

[0025] This device forms a retractable dynamic support structure through a bracket 1 set on the civil engineering platform 200, a support frame 2 fixedly connected to the coal loading car, a sliding support platform 3, and a drive mechanism 4. When the coal loading plate 100 enters the unsupported area 1000mm from the coke oven opening, the drive mechanism 4 drives the support platform 3 to slide along the support frame 2 and abut against the bottom of the coal loading plate 100. Together with the support structure of the coal loading car itself, it can bear the weight of up to 40 tons of coal cake, preventing the coal loading plate 100 from deforming due to suspended load, and ensuring the stability and safety of coal loading operations.
