Description

Technical Field

[0001] The invention relates to the field of chimney escape platforms, in particular to a chimney escape platform. Background Art

[0002] A chimney is a structure that provides ventilation for hot flue gases or fumes from a boiler, furnace, stove or fireplace. Chimneys are usually vertical, or as close to vertical as possible, to ensure a smooth flow of gases, drawing air into the so-called chimney combustion or chimney effect. The space within the chimney is called the flue. Chimneys may be found in buildings, steam locomotives and ships. In actual use, chimneys are often equipped with escape platforms to ensure the safety of their operators so that operators on the chimney can escape in time.

[0003] However, the current chimney escape platforms still have some shortcomings. For example, most of the existing chimney escape platforms are stepped, which requires workers to run down the stairs one by one when a fire occurs inside the chimney, thereby causing certain interference with the escape speed of the workers and thus posing certain safety hazards.

[0004] Therefore, it is urgent to improve this shortcoming. The present invention studies and improves the existing structural deficiencies and provides a chimney escape platform. Summary of the invention

[0008] Furthermore, the side of the load-bearing step is fixedly connected to the end of the connecting shaft, and the other end of the connecting shaft is rotatably connected to the inside of the escape platform body, and the load-bearing step forms a rotating structure with the escape platform body through the connecting shaft.

[0009] Furthermore, the top of the bearing step is fixedly connected to the bottom of the sealing cover plate, and the sealing cover plate and the bearing step form a fixed structure.

[0010] Furthermore, the inner side of the escape platform body is fixedly connected to the outer surface of the chimney body, and the outer top of the escape platform body is fixedly connected to the bottom of the guide limit plate, and the guide limit plate forms a fixed structure through the escape platform body and the chimney body.

[0011] Furthermore, the buffer protection component includes a protection bracket, a damping buffer mechanism and a rubber buffer pad, and the damping buffer mechanism is fixedly installed at equal distances on the inner surface of the protection bracket, and the rubber buffer pad is embedded and installed on the outer surface of the protection bracket.

[0012] Furthermore, the end of the damping and buffering mechanism is fixedly connected to the inner surface of the protective bracket, and the other side of the damping and buffering mechanism is fixedly connected to the inner side of the guide limit plate, and the protective bracket forms an elastic structure with the guide limit plate through the damping and buffering mechanism.

[0013] Furthermore, the outer inner surface of the protective bracket is fixedly connected to the outer surface of the rubber buffer pad, and the protective bracket and the rubber buffer pad form an integrated structure.

[0014] The present invention provides a chimney escape platform, which has the following beneficial effects: 1. The present invention provides a storage groove and an arc-shaped guide groove, so that the driving motor can drive the connecting shaft to rotate inside the escape platform body during operation, so that the connecting shaft drives the load-bearing step to rotate inside the storage groove, so as to achieve the purpose of quickly retracting and releasing the load-bearing step and the sealing cover plate. When the operator on the chimney finds that a fire occurs inside the chimney body, the driving motor can be turned on by the control button, so that the load-bearing step drives the sealing cover plate to be automatically stored inside the storage groove, and then the escape platform body is automatically switched from a step-type to a slide-type, avoiding the situation that the operator needs to run down the stairs step by step when a fire occurs inside the chimney, causing the operator's escape speed to be disturbed.

[0015] 2. The present invention provides a damping and buffering mechanism so that the protective bracket can provide good buffering when it is hit, so that the operator will not be injured when accidentally hitting the buffering and protective component while sliding down along the top of the escape platform body to escape, thereby greatly increasing the escape efficiency and personal safety of the operator, and the rubber buffer pad is provided to prevent the operator from being easily injured when hitting the buffering and protective component.
