Abstract
The utility model belongs to the technical field of chain grate equipment in the metallurgy industry, and particularly relates to a flexible control device for return stroke of a comb board of a chain grate. The flexible control device comprises a slide track, an ejector rod, a guide chain, a counter weight and a guide wheel, a slide track connecting seat is arranged at the lower end of the slide track, the left side of the slide track connecting seat is connected with a spring and horizontal draw bar device, and the right side of the slide track connecting seat is hinged with the upper end of a guide chain. The spring and horizontal draw bar device consists of a horizontal draw bar, a support, a spring fixing sleeve, a spring , a spring moving sleeve, a gasket and an adjusting nut. The flexible control device has the advantages that the flexible control device realizes double-limitation control to the slide track, realizes automatic adjustment, and avoids turning of the comb board, local abrasion of the guide chain and breakage accidents.
Description
Technical field
The utility model belongs to technical field of metallurgical equipment, particularly a kind of drying grate grate plate backhaul Flexible Control device.
Background technology
Drying grate is the major equipment of pellet formation.Head at this drying grate is provided with the shovel flitch, and this shovel flitch and frame are compared and connect, and is provided with drying grate grate plate backhaul control device below the shovel flitch, in order to the upset of restriction grate plate, prevents to shovel flitch by jack-up.Drying grate grate plate backhaul Flexible Control device is located at the push rod on the frame by comparing the guide rail that connects with frame, and what be connected with the lower end of guide rail leads chain and counterweight, and leads the guide deflection sheave that chain is connected with a joggle and forms.The shortcoming of this structure has: 1) vibration of equipment operation generation causes the bolt-adjustment nut loosening of fixed mandril easily, in case it is loosening, slide rail is extruded easily and turns over, break away from the castor bed simultaneously, this moment, slide rail just can not well limit the upset of grate plate, cause the shovel flitch by grate plate lift, pellet on the grate bed can't enter rotary kiln baking and directly drain on the platform from the slide rail below, produce and leak the material phenomenon.2) position of slide rail only by single push rod adjustment with fixing, the coupled chain position of leading is adjusted untimelyly, causes the concentrated wear of leading chain easily, even ruptures.
Summary of the invention
The purpose of this utility model provides a kind of two spacing control, adjusts automatically, and is simple in structure, the drying grate grate plate backhaul Flexible Control device of stable performance.
The purpose of this utility model realizes by following technical proposals:
Drying grate grate plate backhaul Flexible Control device of the present utility model, comprise head that is located at drying grate and the slide rail that is hinged by hinged-support and frame, be located on the described frame and the push rod that is abutted against mutually of the left surface of slide rail bottom therewith, lead chain and lead the counterweight that the lower end of chain is hinged therewith, lead the guide wheel that chain is connected with a joggle therewith, the lower end that it is characterized in that described slide rail is provided with a slide rail Connection Block, the left end of this slide rail Connection Block is connected with a spring horizontal pull rod device, and the right-hand member of this slide rail Connection Block and described upper end of leading chain are hinged.
Described spring horizontal pull rod device is by the girt that is connected with the slide rail Connection Block, the bearing that is slidingly connected of girt therewith, the fixedly connected spring retaining sleeve of bearing therewith, be located at the spring on this spring retaining sleeve outside surface, the spring that is slidingly connected of the internal surface of spring retaining sleeve moves cover therewith, is located at the packing ring of end of described spring and the adjustment nut that is threaded with the termination of described girt and forms.
Advantage of the present utility model:
The utility model keeps the advantage of original structure, and the structure of slide rail is improved, and adopts the spring horizontal pull rod device that the position and the working order of slide rail are rationally controlled, and both it had certain elastic resistnace, realized slide rail again, led the two spacing control of chain.Thereby avoid grate plate upset, lead the concentrated wear of chain and the generation of fracture accident.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing figure of the utility model Fig. 1.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
As Fig. 1, shown in 2, drying grate grate plate backhaul Flexible Control device of the present utility model, comprise head that is located at drying grate 10 and the slide rail 2 that is hinged by hinged-support and frame 8, be located on the described frame 8 and the push rod 3 that is abutted against mutually of the left surface of slide rail 2 bottoms therewith, lead chain 5 and lead the counterweight 7 that the lower end of chain 5 is hinged therewith, lead the guide wheel 6 that chain 5 is connected with a joggle therewith, the lower end that it is characterized in that described slide rail 2 is provided with a slide rail Connection Block 2-1, the left end of this slide rail Connection Block 2-1 is connected with a spring horizontal pull rod device 4, in order to adjust the swing position of slide rail 2, right-hand member and the described upper end of leading chain 5 of this slide rail Connection Block 2-1 are hinged.
Described spring horizontal pull rod device 4 is drawn the 4-1 bar by the level that is connected with slide rail Connection Block 2-1, the bearing 4-2 that is slidingly connected of girt 4-1 therewith, the fixedly connected spring retaining sleeve 4-3 of bearing 4-2 therewith, be located at the spring 4-4 on this spring retaining sleeve 4-3 outside surface, the spring that is slidingly connected of the internal surface of spring retaining sleeve 4-3 moves cover 4-6 therewith, is located at the packing ring 4-5 of end of described spring 4-4 and the adjustment nut 4-7 that is threaded with the termination of described girt 4-1 and forms.
Working method: adjust the position of push rod 3, withstand slide rail 2, make slide rail 2 press close to the castor bed, can realize that the front end of slide rail is spacing; Nut 4-7 is adjusted in rotation, can realize the adjustment of slide rail 2 front and back positions, and the relative position of regulating slide rail and comb bed is best, can prevent slide rail upset backward simultaneously.
The utility model is simple in structure, and less investment has reduced failure rate of machinery, improves the work-ing life of drying grate, reduces the maintenance cost of equipment.
