Abstract
The utility model relates to a heavy hammer frictionless type heating furnace doorseal closing structure. The heavy hammer frictionless type heating furnace doorseal closing structure comprises a furnace door and a hoisting chain. The heavy hammer frictionless type heating furnace doorseal closing structure is characterized in that a parallel rail is arranged in the up and down mobile direction along the furnace door, two reverse wheels are installed in the parallel rail, the reverse wheels are both installed on driving levers, the driving levers are installed on the furnace door in a hinged mode, a stay rope is arranged between the front ends of the two driving levers, a heavy hammer is connected at a position located at the lower position of the stay rope of the driving levers, the hoisting chain is respectively connected with the two driving levers which are arranged in an up and down mode, a supporting wheel is arranged at the lower position of the furnace door, and limiting adjusting blocks are arranged at the lower positions of the driving levers. In the process of actual use, relative motion does not occur between the furnace door and a furnace door frame, and therefore friction between the furnace door and the furnace door frame is avoided. The heavy hammer frictionless type heating furnace doorseal closing structure has the advantages of being simple and reliable in structure, free of additionally installing a pushing device, and capable of lowering work quantity of repair and maintenance and saving operating cost. Consequently, fault points are lowered, and maintenance cost is reduced.
Description
Technical field
The utility model belongs to heating furnace manufacturing technology field, and particularly relating to a kind of weight does not have friction-type heating fire door envelope closing structure.
Background technology
Cell-type Compaction of Heating Furnace Door enclosed construction in using at present has three classes; 1, deadweight sealing compressing structure promptly utilizes track or wedge baffle plate; 2, mechanical close compressing structure uses electric pushrod or air-leg; 3, chassis fire door integrative-structure relies on trolley running to compress sealing.The deficiency that said structure exists is: 1, the deadweight sealing is pressed on sealing moment fire door has friction with doorframe, and the doorframe fiber cotton maintenance workload that easily comes off is big, and the later stage bad sealing of working continuously is run away; 2, mechanical close compresses because of work under bad environment fault rate height, the big operating cost height of maintenance load; 3, chassis fire door integrative-structure relies on trolley running to compress sealing, work-handling sight line limited operation inconvenience.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to use, do not have friction, safe and reliable weight does not have friction-type heating fire door envelope closing structure.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of weight does not have friction-type heating fire door envelope closing structure, comprise fire door and elevator chain, it is characterized in that: be provided with parallel orbit moving up and down direction along fire door, two reverse wheels are installed in the described parallel orbit, each reverse wheel is installed on the activation lever, each activation lever all is hingedly mounted on the fire door, be provided with stay cord between the front end of two activation lever, connect weight on the stay cord of the activation lever below being positioned at, described elevator chain connects two activation lever up and down respectively, the below that is positioned at fire door is provided with support wheel, and the below of described activation lever is provided with spacing adjustment piece.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, relative motion does not take place between fire door and the firedoor frame, thereby avoid friction between the two, simple and reliable for structure, reduction maintenance and upkeep operation amount of the utility model in addition, save operating cost, need not extra the installation and promote dress, thereby reduced the trouble point, reduced maintenance cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, fire door; 2, elevator chain; 3, parallel orbit; 4, reverse wheel; 5, activation lever; 6, bearing pin; 7, stay cord; 8, weight; 9, support wheel; 10, spacing adjustment piece.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of weight does not have friction-type heating fire door envelope closing structure, comprise fire door 1 and elevator chain 2, be provided with parallel orbit 3 moving up and down direction along fire door 1, two reverse wheels 4 are installed in the described parallel orbit 3, each reverse wheel is installed on the activation lever 5, each activation lever all is hingedly mounted on the fire door 1 by bearing pin 6, be provided with stay cord 7 between the front end of two activation lever 5, connect weight 8 on the stay cord of the activation lever 5 below being positioned at, described elevator chain 2 connects two activation lever 5 up and down respectively, and the below that is positioned at fire door 1 is provided with support wheel 9, and the below of described activation lever 5 is provided with spacing adjustment piece 10.
Utilize fire door elevator chain, reverse wheel, activation lever, reach weight, after dropping on the support wheel under the fire door, fire door descends and stops, and weight continues to descend, activation lever makes reverse wheel move the pulling fire door under the restriction of track and moves to doorframe, and then reaches the purpose that sealing compresses.When the fire door elevator chain promotes fire door, mention earlier after weight, activation lever move down the track reverse wheel to push fire door open.Fire door promotes and opens, and fire door leaves the distance of doorframe and adjusts consistent by the spacing adjustment piece of lever bottom.
The above only is to preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification all belong in the scope of technical solutions of the utility model.
