The movable fire grate segment of the reverse pushing fire grate is thick and heavy, and a large amount of burned objects are needed to be carried out, and the pushing end of the movable fire grate segment transmission member (commonly provided with a hydraulic cylinder) is directly arranged at the pushing end of the movable fire grate segment transmission member so as to have too large load on the movable fire grate segment transmission member, so that the movable fire grate segment is required to be supported by the supporting component. At present, the movable fire grate is supported by carrier rollers, the carrier rollers can support the movable fire grate and facilitate the reciprocating sliding of the movable fire grate, and the carrier rollers are arranged in supporting plates of the fixed fire grate. However, with the increase of the running time of some put-into-production reverse pushing fire grates, for example, the problem that the steel plate inside the fire grate is deformed due to overheating is also encountered in the patent document with the application number of CN201520809449.2 in a long-term high-temperature environment, and the movable fire grate sheets carrying the incinerated objects reciprocate on the carrier roller, so that the carrying capacity of the movable fire grate sheets is increased when the movable fire grate sheets are pushed out, the carrying capacity of the movable fire grate sheets is reduced when the movable fire grate sheets are retracted, the supporting plates of the fixed fire grate sheets are equivalent to being subjected to a variable force, and under the common influence of the high-temperature environment and the variable force, the deformation of the supporting plates of the conventional fixed fire grate sheets is increased, so that the carrier roller is shifted, and the movable fire grate sheets deviate from the normal sliding track, so that the movable fire grate sheets and the fixed fire grate sheets are rubbed or the movable fire grate sheets are tilted. The utility model provides a movable grate segment supporting component which can provide higher strength.

In order to solve the technical problems, the utility model provides a supporting component of a movable grate segment of a reverse pushing grate, which comprises: the two ends of the cross beam are respectively connected with the fire grate main frame; the rollers are uniformly inverted on the cross beam; and the movable fire grate segment sliding frame is arranged on the roller and is connected with the movable fire grate segment transmission piece.
Further, the cross beam is obliquely arranged so that the bottom plate of the roller is obliquely downward.
Further, the ratio of the width of the roller to the length of the cross beam is 0.9-1.1:11.5-12.5.
Further, the ratio of the total width of the plurality of rollers to the length of the cross beam is 1.8-3.3:11.5-12.5.
Further, a reinforcing angle plate is arranged between the cross beam and the main fire grate frame.
The utility model aims to solve the technical problem that the strength of the existing supporting component based on the fixed fire grate supporting plate is insufficient, and the movable fire grate supporting component of the reverse push fire grate adopts the supporting mode that a cross beam is additionally arranged in a main fire grate frame and a roller and a movable fire grate sliding frame are arranged on the cross beam, so that the integral strength is higher, the service life is longer, and the long-term stable operation of the reverse push fire grate can be effectively ensured.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments of the present utility model that would be within the purview of one of ordinary skill in the art without the particular effort being made are within the scope of the utility model.
Examples
As shown in FIG. 1, the present utility model provides a moving grate segment support assembly for a reverse push grate, comprising: the cross beam 100, both ends of which are respectively connected with the fire grate main frame 200; a plurality of rollers 300 which are uniformly inverted on the cross member 100; the traveling grate segment carrier 400 is disposed on the roller 300, referring to fig. 2, and is coupled to the traveling grate segment driving member 600.
The back-pushing movable fire grate segment supporting component adopts a supporting mode that a cross beam 100 is additionally arranged in a fire grate main frame 200, and a roller 300 and a movable fire grate segment sliding frame 400 are arranged on the cross beam 100, wherein the movable fire grate segment sliding frame 400 is used for arranging movable fire grate segments, a movable fire grate segment transmission piece 600 is connected with the movable fire grate segment sliding frame 400, and the movable fire grate segment sliding frame 400 is pushed to slide back and forth on the roller 300, so that the reciprocating motion of the movable fire grate segments is realized. The additional beam has higher strength than the supporting plate for fixing the fire grate segment, and is not easy to deform due to high temperature and variable force, thereby ensuring that the sliding track of the movable fire grate segment supported by the assembly is unchanged for a long time.
As shown in fig. 2, the cross beam 100 may be disposed obliquely, so that the bottom plate 310 of the roller 300 may be inclined downward, thereby avoiding dust accumulation on the roller 300, ensuring normal rotation of the roller 300, and reducing the sliding resistance of the movable grate segment sliding frame 400.
The ratio of the width of the roller 300 to the length of the cross beam 100 is 0.9-1.1:11.5-12.5.
