Abstract
The utility model provides a trolley traveling device, which comprises a movable rail, a roller, a pin shaft, a connecting plate and a connecting rod. Under the traction of external force, the trolley rolls the roller contacted with the trolley through the movable rail, so that the roller assembly of the whole device is dragged to move forwards (or backwards), and the speed of the roller assembly, namely the speed of the center of the roller, is equal to half of the speed of the trolley. The utility model has the advantages of low processing precision requirement, low manufacturing cost, small walking resistance, long service life and the like. The trolley is suitable for the trolley with reciprocating stroke in the industrial furnace.
Description
The utility model relates to a kind of trolley running device that industrial furnace has reciprocating travel that is used for.
The chassis of the reciprocating travel that existing various industrial furnaces are used, energy-conservation owing to requiring on the one hand, the chassis lower space is little, and it is also little to walk wheel diameter, so number is many, accuracy of manufacture and tooling cost height; Because the residing temperature of travelling wheel is higher, adopt the antifriction-bearing box or the plain bearing of standard on the other hand, interior lubricated material poor heat resistance and insufficient lubrication cause resistance to increase even stuck, and actuating device is excessive impaired because of loading, and influence is produced.
The purpose of this utility model is to provide that a kind of requirement on machining accuracy is low, manufacturing cost is little, walking resistance is little, the trolley running device of long service life.
The purpose of a kind of trolley running device of the utility model is achieved in that on the pre-buried quiet rail in the ground of trolley running, place several rollers, be installed with bearing pin in the roller centre hole, the gap that keeps 1～2mm therebetween and preferably, also fixing in the hole on the connecting plate on corresponding respectively insertion roller both sides, bearing pin two ends, constitute the roll wheel assembly that has certain distance between roller thus.So roll wheel assembly also has row on the quiet rail of ground-surface another root of trolley running, links up by a pitman again between the two row roll wheel assemblies, makes two row roll wheel assemblies have identical running velocity.Above two row roll wheel assemblies, place the moving rail that is fixed on the dull and stereotyped bottom of chassis and get final product then.
A kind of trolley running device of the utility model compared with prior art has following characteristics:
1. because roller has only the working accuracy of cylindrical and roughness of surface to have outside the requirement, remaining part or position processing request are low, so tooling cost is little, accuracy of manufacture is low;
2. because the stress point of roller on cylindrical, does not resemble common bearing support pattern stress point on cylindrical and endoporus, so its bearing capacity is big, and running resistance is little;
3. because the gap between roller and the bearing pin is bigger, so the influence of not temperature distortion;
4. more owing to the roller number, and be quick condition, so wearing and tearing are evenly, long service life.
Below in conjunction with accompanying drawing a kind of trolley running device of the utility model is done detailed description.
Fig. 1 is the front view of a kind of trolley running device of the utility model, also is specification digest accompanying drawing of the present utility model.
1 is moving rail among Fig. 1, and 2 is roller, and 3 is bearing pin, and 4 is connecting plate, and 5 is pitman, and 6 is quiet rail, and 7 is the chassis flat board.On the pre-buried quiet rail 6 in the ground of trolley running, place several rollers 2, be installed with bearing pin 3 in roller 2 centre holes, also fixing in the hole on the connecting plate 4 on corresponding respectively insertion roller 2 both sides, bearing pin 3 two ends, constitute the roll wheel assembly that has certain distance between roller thus, so roll wheel assembly also has row on the quiet rail 6 of another pre-buried root of the ground of trolley running, link up by a pitman 5 again between the two row roll wheel assemblies, above two row roll wheel assemblies, place the moving rail 1 that is fixed on dull and stereotyped 7 bottoms of chassis then.
There is a colyliform projection at roller 2 middle parts, and the vacancy position of corresponding moving rail 1 and quiet rail 6 skids off track to guarantee that roller 2 is unlikely to be in operation because of axial motion.
During use, make two rollers 2 of whole device one end also concordant earlier with the spacing place that chassis flat board 7 is in quiet rail 6, chassis is under the traction of external force, by moving rail 1 roller 2 of contact is with it rolled, so just drag roll wheel assembly (or backward) operation forward of whole device, and the speed of roll wheel assembly is that the speed at roller 2 centers equals half of chassis speed, therefore equal a half of the stroke of quiet rail 6 when the stroke of roll wheel assembly, it is spacing that two rollers 2 of the other end of chassis dull and stereotyped 7 and roll wheel assembly just arrive at quiet rail 6 other ends simultaneously, thereby guarantee that chassis can not drop down from roll wheel assembly in whole process.
Claims (1)
1. trolley running device, by moving rail (1), roller (2), bearing pin (3), several parts of connecting plate (4) and pitman (5) are formed, it is characterized in that on the pre-buried quiet rail (6) in the ground of trolley running, place several rollers (2), be installed with bearing pin (3) in roller (2) centre hole, also fixing in the hole on the connecting plate (4) on corresponding respectively insertion roller (2) both sides, bearing pin (3) two ends, constitute the roll wheel assembly that has certain distance between roller thus, so roll wheel assembly another root quiet rail (6) pre-buried on the ground of trolley running gone up and also had row, link up by a pitman (5) again between the two row roll wheel assemblies, above two row roll wheel assemblies, place the moving rail (1) that is fixed on chassis flat board (7) bottom then.
