Description
Technical field
The utility model relates to a kind of hot air isolating door locking mechanism, for the mechanism of door-plate and the doorframe lock tightening seal of isolation door, belongs to the isolation door technical field specifically.
Background technology
Along with the fast development of fired power generating unit, coal pulverizer is also corresponding developed as the main powder manufacturing apparatus of large-size thermal power plant.Coal pulverizer has the advantages such as reduced investment, power consumption are low, easy operation, but also has the shortcomings such as easily wearing and tearing, repair time are long.Because coal pulverizer powder process ability direct relation exerting oneself of generating set, so the quality of coal pulverizer quality directly has influence on the normal operation of whole power plant.
Isolation door is as the main xegregating unit of coal pulverizer and steam generator system, the most important thing especially in system.When coal pulverizer puts into effect, isolation door must reliable be opened, and when coal pulverizer, isolation door must the safety isolation during in standby or maintenance, and the open and close of isolation door are had to the regular hour requirement.Because the residing operating temperature of isolation door is high, duct cross-section is large, stressed large, leakproofness, the reliability requirement of closing high simultaneously, and domestic isolation door all can not reach very desirable duty, this normal operation to coal pulverizer and maintenance have formed very large potential safety hazard.
Existing isolation door mainly is comprised of doorframe, door-plate and driving mechanism, between the surrounding of door-plate and doorframe part, is provided with weather strip.Door-plate is locked at door-plate in doorframe by the retaining mechanism on door-plate after promoting to put in place by driving mechanism.Because the door-plate size is larger, at long-term door-plate wearing and tearing or the door plate deformation of easily occurring in service, cause the position between door-plate and doorframe to change, thus the generator gate body is not closed completely, hot blast leaks phenomenon, the normal operation of serious threat coal pulverizer and maintainer's safety.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of hot air isolating door locking mechanism is provided, and can adjust the relative position between door-plate and doorframe, has improved the sealing between door-plate and doorframe, has improved maintainer's safety.
The technical scheme provided according to the utility model, the hot air isolating door locking mechanism comprises the first connecting lever seat and the second connecting lever seat, the first connecting lever seat connects two the first connecting levers by bearing pin, the second connecting lever seat connects two the second connecting levers by bearing pin, it is characterized in that: described the first connecting lever seat one end connects head rod, the second connecting lever seat one end connects the second connecting rod, between head rod and the second connecting rod, by adjusting screw(rod), connects.
Further, connect the first locking nut on adjusting screw(rod), by the first locking nut locking, be connected to the head rod on adjusting screw(rod).
Further, connect the second locking nut on adjusting screw(rod), by the second locking nut locking, be connected to the second connecting rod on adjusting screw(rod).
Compared with the prior art the utility model has the following advantages:
The utility model structure is ingenious, compact, reasonable, can adjust the relative position between door-plate and doorframe, has improved the sealing between door-plate and doorframe, has improved maintainer's safety; Door-plate is opened flexibility and reliability.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-the first connecting lever seat, 2-the first connecting lever, 3-head rod, 4-the first locking nut, 5-adjusting screw(rod), 6-the second locking nut, 7-the second connecting rod, 8-the second connecting lever, 9-the second connecting lever seat.
The specific embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the utility model mainly comprises that the first connecting lever seat 1 and the second connecting lever seat 9, the first connecting lever seats 1 connect 2, two first connecting lever 2 other ends of two the first connecting levers by bearing pin and connect respectively the first door-plate and the second door-plate by bearing pin.The second connecting lever seat 9 connects 8, two second connecting lever 8 other ends of two the second connecting levers by bearing pin and connects respectively the first door-plate and the second door-plate by bearing pin.
Described the first connecting lever seat 1 one ends connect head rod 3, the second connecting lever seat 9 one ends and connect the second connecting rod 7, between head rod 3 and the second connecting rod 7, by adjusting screw(rod) 5, connect.
Connect the first locking nut 4 on described adjusting screw(rod) 5, by the first locking nut 4 lockings, be connected to the head rod 3 on adjusting screw(rod) 5.
Connect the second locking nut 6 on described adjusting screw(rod) 5, by the second locking nut 6 lockings, be connected to the second connecting rod 7 on adjusting screw(rod) 5.
Operating principle of the present utility model is: between adjusting screw(rod) 5 and head rod 3 and the second connecting rod 7, for being threaded, therefore can regulate the distance between head rod 3 and the second connecting rod 7, thereby adjust the parallelism of the first door-plate 2 and the second door-plate 3.After adjusting to the right place, by the first locking nut 4 and the second locking nut 6, the position of head rod 7.3 and the second connecting rod 7 is locked.The utility model structure is ingenious, compact, reasonable, by adjusting screw(rod) 5, can adjust the relative position between door-plate and doorframe, has improved the sealing between door-plate and doorframe, has improved maintainer's safety; Door-plate is opened flexibility and reliability.
