A bottom end of the connecting rod is provided with a fixing frame, the connecting rod is connected with a bracket on top of the fixing frame by a limit device; the gravity device is connected at the bottom of the fixing frame, a lifting device is provided inside the fixing frame and a top end of the lifting device is connected with the fixing frame. The utility model is a space adjustment device for a chain grate with a simple structure, an easy operation and implementation of the safety online adjustment.
Description
Technical field
The utility model is mainly concerned with the drying grate field, refers in particular to a kind of drying grate lash adjusting device that is used for adjusting gap between drying grate end shovel flitch and the chain comb device.
Background technology
Drying grate is a kind of Thermal Equipment of at high temperature working, drying grate will contain on the grate plate that the iron ball material is placed on slow running, utilize the thermal current of central cooler waste heat recovery that green-ball is carried out drying, preheating, oxidation concretion, then directly send into rotary kiln and carry out roasting, in this process, the transmission mechanism of drying grate is the chain transmission.In the prior art, drying grate should keep certain interval between drying grate end shovel flitch and the chain comb device when operate as normal.The effect of shovel flitch is the material of rooting out on the grate plate (acid pellet), therefore, requires the slit between shovel flitch and the grate plate the smaller the better in theory.But because grate plate is a moving component that moves with the bed of combing, if do not reserve certain slit (2mm is advisable), then shovel between flitch and the grate plate and may cause the normal movement of influence comb bed and influence the drying grate normal operation because of grate plate machining accuracy error (grate plate is a cast member) produces fricting movement; Influence the service life of grate plate because of the wearing and tearing grate plate.Existing adjusting device comprises gravity installation and connecting rod, and the top of connecting rod is articulated in the shovel flitch, and its bottom links to each other with gravity installation.Under the effect of gravity installation, connecting rod drives the shovel flitch and keeps certain clearance., because need making when changing, the variation of operating mode, therefore must under stopped status, can finish when this gap because shovel flitch etc. all are positioned at the high-temperature region, complicated operation, and poor stability, and cause the complete machine operating efficiency low.Secondly, connecting rod is positioned at the high-temperature region for a long time, so reduces greatly its service life, not only influences the precision of its adjusting play, also causes replacing, maintenance trouble.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of simple in structure, easy and simple to handle, the drying grate lash adjusting device that can realize the online adjustment of safety.
For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of drying grate lash adjusting device, it comprises gravity installation and the connecting rod that links to each other with the shovel flitch, it is characterized in that: the bottom of described connecting rod is provided with fixed frame, and connecting rod links to each other by the support of stopping means with the fixed frame top; Described gravity installation is connected in the bottom of fixed frame, is provided with jacking apparatus in the fixed frame, and the top of jacking apparatus links to each other with fixed frame.
The outside of described connecting rod epimere is provided with the cold air sleeve, and the cold air sleeve is wrapped in the outside of connecting rod, and the cold air sleeve is communicated with refrigerator pipe.
Described stopping means is a locking nut, and connecting rod links to each other by the support of locking nut with the fixed frame top.
The bottom of described jacking apparatus is provided with supporting seat, and supporting seat is positioned on the brace summer of drying grate.
Compared with prior art, advantage of the present utility model just is:
1, the utility model is simple in structure, easy to operate, by lifting body connecting rod is carried out jacking, just can move in vertical direction by control link, the shovel flitch motion at drivening rod top, finish adjustment to gap between drying grate end shovel flitch and the chain comb device, after adjustment finishes, stopping means locking is got final product; Whole process is all finished at low-temperature space, does not need shutdown operation, thereby has reduced labour intensity, improved operating efficiency;
2, the utility model is being in the connecting rod epimere outside parcel cold air sleeve of high temperature section, from cool air hose advance cold wind it is carried out air-cooled, thereby can prevent connecting rod at high temperature high temperature expand, prevent its precise decreasing, and prolong the service life of connecting rod.

The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As shown in Figure 1, the utility model drying grate lash adjusting device, it comprises connecting rod 4 and gravity installation 3, the top of connecting rod 4 links to each other with shovel flitch 7, the bottom of connecting rod 4 is provided with fixed frame 2, connecting rod 4 links to each other with the support 11 of fixed frame 2 tops by stopping means 8, and support 11 is fixed on the bone beam of drying grate, and stopping means 8 can down move by limiting rod 4; Gravity installation 3 is connected in the bottom of fixed frame 2, is provided with jacking apparatus 1 in the fixed frame 2, and the top of jacking apparatus 1 links to each other with fixed frame 2.In the present embodiment, gravity installation 3 is a gravity drop hammer, and stopping means 8 is a locking nut, and connecting rod 4 links to each other by the support 11 of locking nut with fixed frame 2 tops; The bottom of jacking apparatus 1 is provided with supporting seat 9, and supporting seat 9 is positioned on the brace summer 10 of drying grate.Jacking apparatus 1 adopts jack, can move in vertical direction by the connecting rod 4 of control connection in its top by jack.In the present embodiment, the outside of connecting rod 4 epimeres is provided with cold air sleeve 6, and cold air sleeve 6 is wrapped in the outside of connecting rod 4, and cold air sleeve 6 is communicated with refrigerator pipe 5.Because the epimere of connecting rod 4 is a high temperature section, from cool air hose 5 advance cold wind it is carried out air-cooled, can effectively prevent connecting rod 4 at high temperature high temperature expand.
Operation principle: during the drying grate operate as normal, stopping means 8 is locking state, and connecting rod 4 is locked on the support 11, prevents that connecting rod 4 from down moving; Under the gravity effect of gravity installation 3, keep certain interval between the shovel flitch 7 at connecting rod 4 drive tops and the chain comb device; When the gap is adjusted between needs are to drying grate end shovel flitch 7 and chain comb device, fixed frame 2, connecting rod 4 that control jacking apparatus 1 drives its top are done upper and lower motion, connecting rod 4 correspondingly drives shovel flitch 7 motion at its top, and the gap between itself and the chain comb device is adjusted; After adjustment finishes, stopping means 8 lockings are got final product.
