Description

Technical Field

[0001] The utility model relates to the technical field of sintering trolley panel gap sealing, in particular to a sealing structure at the gap of the sintering trolley panel. Background Art

[0002] The sintering trolley is the main equipment for the operation of the sintering machine. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine. At present, for the trolleys used in the sintering plant during operation, there are connecting gaps between their panels. These gaps will cause air leakage during the operation of the trolley. This situation is caused by the design of the trolley, and such gaps are inevitable. Since the output of sintered ore is proportional to the air volume of the sintering trolley, the increase in the air leakage volume will result in useless work during the sintering process, thus affecting the output of sintered ore and also causing waste of the power of the main induced draft fan.

[0003] At present, the commonly used sealing method for the gaps between the trolley panels is to add sealing gaskets to the gaps. However, due to design and production process reasons, the sizes of the gaps at the panel are different, and different thicknesses of the panels also have requirements for the thickness of the sealing gaskets, which results in greatly different sizes of the used sealing gaskets, bringing great inconvenience to the normal sealing work. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing sealing of the gaps between the trolley panels generally uses sealing gaskets. This sealing method cannot be applied to gaps of different sizes, and at the same time, it cannot adapt to trolley panels of different thicknesses, resulting in a small application range.

[0005] To solve the above problems, the technical solution adopted by the utility model is a sealing structure at the gap of the sintering trolley panel, including two panel bodies. A sealing structure is provided between the two panel bodies. The sealing structure includes two baffle plates. Grooves are opened on the opposite sides of the two baffle plates. Limiting slideways are opened on both the upper and lower sides of the grooves. Two top plate structures are arranged in the grooves. A plurality of compression springs are clamped between the two top plate structures.

[0006] As a further scheme of the utility model: The top plate structure includes an outer baffle plate. A sliding groove is opened on one side of the outer baffle plate. An inner baffle plate is slidably arranged in the sliding groove. A plurality of small tension springs are fixed between one side of the inner baffle plate and one side inside the sliding groove to facilitate adapting to trolley panels of different thicknesses.

[0007] As a further scheme of the utility model: Sliders are fixed at the mutually remote ends of the upper and lower sides of the outer baffle plate and the inner baffle plate, and the sliders slide in the limiting slideways to limit the position of the top plate structure.

[0008] As a further solution of the utility model: on the side of the two baffles opposite to each other and close to the top, inner sliding rods are fixedly installed, and grip cylinders are sleeved outside the inner sliding rods, so as to facilitate pulling out the structure from the gap.

[0009] As a further solution of the utility model: the natural length of the compression spring is greater than the width of the groove to prevent the compression spring from falling off from the limit ring block.

[0010] As a further solution of the utility model: the maximum elongation length of the small tension spring is less than the depth of the chute to prevent the inner baffle from detaching from the outer baffle.

[0011] As a further solution of the utility model: on one side of the outer baffle at the position of the compression spring, a limit ring block is fixed to limit the position of the compression spring.

[0012] The advantages of the utility model compared with the prior art are as follows: 1. This patent adds two top plate structures and a compression spring. By inserting the two top plate structures between the two fence body parts, and then using the compression spring to push the two top plate structures in opposite directions, so that the two top plate structures are tightly attached to the fence body, in order to adapt to gaps of different sizes;

[0013] 2. It adds an outer baffle and an inner baffle structure, as well as a small tension spring. By using the small tension spring to tighten the distance between the outer baffle and the inner baffle, it is convenient to tighten the distance between the two baffles connected to the outer baffle and the inner baffle, so as to be applicable to fence bodies of different thicknesses.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] The present invention provides a technical solution: to solve the existing problems proposed in the background technology.

[0023] Combined with the attached Figures 1 - 3 It can be known that the structure includes two baluster bodies 1, and a sealing structure is provided between the two baluster bodies 1. The sealing structure includes two baffles 2. Grooves 2.1 are opened on both sides of the two baffles 2 facing each other. Limit slideways 2.2 are opened on the upper and lower sides of the grooves 2.1 to facilitate restricting the sliding range of the top plate structure 3. Two top plate structures 3 are provided in the grooves 2.1, and a plurality of compression springs 4 are clamped between the two top plate structures 3 to facilitate pushing the two top plate structures 3 outwards.

[0024] Combined with the attached Figure 3 、 4 It can be seen that the top plate structure 3 includes an outer baffle 3.1. A slide groove 3.2 is opened on one side of the outer baffle 3.1. An inner baffle 3.3 is slidably provided in the slide groove 3.2. A plurality of small tension springs 3.4 are fixed between one side of the inner baffle 3.3 and one side inside the slide groove 3.2 to facilitate adapting to baluster bodies 1 of different thicknesses; sliders are fixed at the upper and lower ends of the outer baffle 3.1 and the inner baffle 3.3 away from each other, and the sliders slide in the limit slideways 2.2 to limit the position of the top plate structure 3; Inner slide bars 2.3 are fixed near the top on both sides of the two baffles 2 facing each other, and a grip cylinder 5 is sleeved outside the inner slide bars 2.3 to facilitate pulling the structure out of the gap; the natural length of the compression spring 4 is greater than the width of the groove 2.1 to prevent the compression spring 4 from falling off from the limit ring baffle 3.5; the maximum elongation length of the small tension spring 3.4 is less than the depth of the slide groove 3.2 to prevent the inner baffle 3.3 from detaching from the outer baffle 3.1; a limit ring baffle 3.5 is fixed on one side of the outer baffle 3.1 at the position of the compression spring 4 to limit the position of the compression spring 4.

[0025] The working principle of the present application is as follows: when sealing the trolley guardrail, first pull the two baffles 2 to drive the top plate structure 3 to extend. When the top plate structure 3 is subjected to tension, the inner baffle 3.3 will slide to the outside of the slide groove 3.2, and at the same time, the small tension spring 3.4 will be stretched. When the two baffles 2 are pulled to match the thickness of the guardrail body 1, the two top plate structures 3 can be squeezed, and the compression spring 4 can be compressed at the same time. When one end of the two top plate structures 3 can enter the gap between the two guardrail bodies 1, the entire sealing structure can be pressed downward to fill the gap.

[0026] When the entire structure is compressed to close the gap, the two top plate structures 3 will hold up one side of the guardrail body 1 under the reverse thrust of several compression springs 4, thereby playing a fixing role and being suitable for gaps of different sizes. The two baffles 2 will also tighten the guardrail body 1 under the tension of several small tension springs 3.4, thereby achieving the effect of windproof sealing.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
