Detailed Description

The present invention will be described in further detail with reference to examples, but the present invention is not limited thereto.

Examples

As shown in fig. 1, the track assembly of the movable belt conveyor of the present invention comprises two track plate frames 229 oppositely disposed up and down, a track assembly 600 mounted on the two track plate frames 229, and a track position limiter connected to the track assembly 600; the track stops are used to prevent the track assembly 600 from disengaging the track plate housing 229.

Specifically, as shown in fig. 1, 2 and 3, the upper and lower two track plate frames 229 are connected by a connecting plate. The track plate housing 229 includes two track support plates on which the track assembly 600 is mounted. One end of the track support plate is provided with a first recess 231, and the other end of the track support plate is provided with a first protrusion 230 engaged with the first recess 231. When two track assemblies link together, first arch 230 on one track assembly cooperatees with first recess 231 on its adjacent track assembly to make two adjacent track assemblies can form a whole, can not have empty and suitable, when the track subassembly passes through between two track grillages, can both obtain supporting, can not receive empty and appear the card and pause phenomenon, prevent to cause the damage problem to track grillage and track assembly 600. In addition, the track support plate above and the track support plate below can also be connected through the arc plate, and the arc plate is used for transition, so that the track plate frame 229 can better support the track assembly 600.

The track assembly 600 comprises a plurality of rolling track assemblies 601, and the rolling track assemblies 601 are sequentially connected to form an endless chain 603, that is, two adjacent rolling track assemblies 601 are connected by the chain 603, so that the whole track assembly 600 is endless. Since the entire track assembly 600 is endless, the upper track plate 229 supports the upper layer of the track assembly 600 and the lower track plate 229 supports the lower layer of the track assembly 600.

The number of the track limiting devices is the same as that of the rolling track assemblies 601, and the track limiting devices are arranged on the inner side face of each rolling track assembly 601. Specifically, the track limiting device comprises a limiting groove 232 arranged on the track plate frame 229 and a track limiting structure arranged on the inner side of the rolling track assembly 601; the limiting groove 232 is located between the two track support plates.

As shown in fig. 4, the track limiting structure includes a scraper U-bolt 602 disposed inside the rolling track assembly 601, two wing plates 604 respectively disposed at two ends of the scraper U-bolt 602, and a sliding slot 605 is formed between each wing plate 604 and the rolling track assembly 601; the scraper U-bolt 602 is matched with the limiting groove 232, that is, the scraper U-bolt 602 is located in the limiting groove 232, and the edges of the two track support plates are respectively clamped into the two sliding grooves 605, so that the scraper U-bolt 602 cannot be separated from the limiting groove 232.

Roller bearings are respectively installed at two ends of the rolling track assembly 601, and the tangent line of the outer surface of each roller bearing is slightly higher than the upper surface of the rolling track assembly 601, so that the roller bearings can be in contact with track supporting plates. When the track assembly moves on the track shoe frame, sliding friction can be changed into rolling friction, and resistance in driving can be greatly reduced.

The lateral surface of track backup pad is equipped with the non-skid stud to increase the frictional force between track backup pad and track assembly 600.

As described above, the utility model discloses alright fine realization.
