Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and more specifically, to a heat-insulating guardrail for a trolley, a new trolley and equipment. Background Art

[0002] The trolley is a key component of the decarbonization machine, sintering machine and roasting machine. On the one hand, the combustion of materials in the trolley will generate high temperature and heat. The long-term high temperature and high heat working environment will easily cause the trolley guardrail to deform, leak air and other adverse effects. On the other hand, when the trolley passes through the ignition zone, the guardrail is burned by the ignition flame and produces thermal cracks. Therefore, the existing trolley guardrails generally have the following defects: First, the heat resistance of the trolley guardrail is not enough to resist the thermal deformation of the guardrail, resulting in increased air leakage of the trolley, which reduces the combustion efficiency of the material in the trolley; second, the temperature difference inside the trolley guardrail is obvious, and the heat load is unevenly distributed, which causes the guardrail to be overheated locally and deformed, and at the same time affects the combustion efficiency of the material in the trolley.

[0003] For example, a utility model patent with announcement number CN220380266U and name "A trolley guardrail and trolley" discloses a trolley guardrail and a trolley, the trolley comprises a trolley body and an upper guardrail body, a lower guardrail body is arranged above the trolley body, the upper guardrail body is arranged above the lower guardrail body, a thermal insulation coating is fixedly connected to the left side of the upper guardrail body, a wear-resistant and anti-corrosion coating is arranged on the left side of the thermal insulation coating, a connecting block 1 is fixedly connected to the right side of the upper guardrail body, a bolt penetrates through the upper interior of the connecting block 1, a clamping rod is fixedly connected to the lower part of the connecting block 1, a connecting block 2 is provided below the clamping rod, a clamping groove is opened on the upper surface of the connecting block 2, a nut is arranged inside the connecting block 2, and a sealing gasket is fixedly connected to the lower part of the upper guardrail body. In the above technical scheme, a heat-insulating coating is arranged on the left side of the upper guardrail body, which improves the heat resistance of the trolley guardrail to a certain extent. However, the heat-resistant coating is easy to fall off under long-term high-temperature combustion environment. After long-term use, this type of trolley guardrail is not sufficient to resist thermal deformation of the guardrail. At the same time, the above scheme cannot overcome the defects of large temperature difference inside the trolley guardrail and uneven heat load distribution. Utility Model Content

[0027] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

Compared with the single-layer structure of the existing trolley guardrail, the trolley insulation guardrail provided by the present application adopts a double-layer structure (a double-layer structure of an outer guardrail 3 and an open inner guard plate 1). Only by slightly adjusting the width of the trolley guardrail, the outer guardrail 3 can be effectively prevented from overheating and causing thermal deformation. Compared with the prior art of coating a thermal insulation material on a single-layer plate as a thermal insulation layer, the present application fills the thermal insulation layer 2 in the accommodating cavity formed by the outer guardrail 3 and the open inner guard plate 1, thereby avoiding the thermal insulation layer 2 from falling off in a long-term high and low temperature alternating working environment, thereby improving the service life of the thermal insulation layer 2. At the same time, it also ensures the long-term working characteristics of the thermal insulation layer 2 and the service life of the trolley guardrail. The shape and height of the outer guard plate 3 and the open inner guard plate 1 can be effectively adjusted according to the internal structure of the decarburizing machine, sintering machine or roasting machine.

The upper railing 31 and the middle railing 32 are arranged in sections, which can change the rod drop position of the rod drop seal, which is not elaborated in detail in this application.

[0033] like Figure 4 As shown, in one of the technical solutions, the open inner guard plate 1 includes an upper guard plate 11 and a lower guard plate 12 arranged in sequence from top to bottom, and the upper guard plate 11 and the lower guard plate 12 are both U-shaped. In the above technical solution, the open inner guard plate 1 is arranged in sections, including the upper guard plate 11 and the lower guard plate 12 arranged up and down, which can effectively balance the distribution of the thermal load of the vertical part of the open inner guard plate, homogenize the temperature difference inside the open inner guard plate, and reduce thermal stress.
