One end of a front baffle opening and closing oil cylinder is articulated on a fixed wall board, and the other end of the front baffle opening and closing oil cylinder is articulated on the front baffle; a locating plate is welded on the front baffle; a bracket used for fixing a locking oil cylinder is welded on a movable wall board; a piston rod of the locking oil cylinder is connected with a wedge-shaped bolt by threads; two locating seats are welded on the movable wall board, opposite to the two sides of the locating plate; the front baffle consists of a front baffle rack and inclined racks; the two inclined racks are respectively welded on the side surface of the front baffle rack, close to the movable wall board and the fixed wall board. The device is used for the side coal charging car of the tamping coke oven, and has the advantages of being simple in structure, large in adjustment range and reliable in locking, and guaranteeing that the coal can not leak when the coal cakes are tamped.
Description
Technical field
The utility model relates to the side coal car of vertical tamping coke oven, particularly switching and the locking gear of the side coal car front apron of vertical tamping coke oven list removable wall.
Background technology
The side coal car of vertical tamping coke oven is under coal tower during tamping briquette, and rear deflector door, movable wallboard, fixedly wallboard, front apron form the coal groove of a rectangle jointly, and front apron can open and close.At present, vertical tamping coke oven list removable wall side coal car all adopts the parallel-moving type front apron opening and closing device of hydraulic oil cylinder driving.Therefore, the locking gear of front apron employing front apron, driving oil cylinder, guiding and coal bin front portion are the structure that is arranged in parallel.Front apron, in moving horizontally, reaches the locking of front apron by being fixed on locking voussoir on fixedly wallboard and movable wallboard.Between this structure front apron and coal bin, front apron bottom and holder coal seam floor, need to keep certain interval, guarantee front apron proper motion.Due to front apron and coal bin and holder coal seam floor poorly sealed, in the process of tamping briquette, from gap location, can constantly leak coal dust, not only affect environmental health, and coal dust drops on holder coal seam floor slideway, can affect the stability of holder coal plate operation.
Utility model content
The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of tamping coking oven side filling coal car front apron to open and close and locking gear, solve current vertical tamping coke oven list removable wall side coal car front apron and coal bin and ask coal seam floor poorly sealed, the problem of leakiness coal in the process of tamping briquette.
The utility model is achieved through the following technical solutions:
A kind of tamping coking oven side filling coal car front apron opens and closes and locking gear, comprise: the front apron that forms Tamping coal runner, fixing wallboard, movable wallboard, and front apron opens and closes oil cylinder, it is characterized in that: described front apron opens and closes the hinge joint of oil cylinder one end on fixing wallboard, one end hinge joint is on front apron in addition, on front apron, be welded with strongback, on movable wallboard, be welded with locking cylinder bracket, fixed latch oil cylinder on locking cylinder bracket, the piston rod head of locking oil cylinder is connected with wedge-shaped bolt male thread, on movable wallboard, both sides corresponding to described strongback are welded with positioning seat, described front apron by front grillage and tiltedly frame form, two oblique framves are welded on respectively front grillage near movable wallboard and the fixing side of wallboard.
The utility model compared with prior art has the following advantages and beneficial effect:
For adapting to the motion flow of the tamping coking oven side filling coal car of single removable wall, front apron opening and closing device of the present utility model has adopted the mode of hydraulic oil cylinder driving rotating open-close, has overcome and has adopted parallel movable opening and closing device to make the poorly sealed problem of front apron and coal bin and holder coal seam floor.Meanwhile, the utility model matching design be arranged on the front apron locking gear on the movable wallboard of coal bin, not only by hydraulic oil cylinder driving wedge, wedge is inserted in the latching slot being formed by movable wallboard and front apron, realize and locking; And utilize the mode that increases oblique frame on front apron, coal dust gear, in coal bin inner side, has effectively been solved to the problem that front apron leaks coal.
The utility model is for the side coal car of vertical tamping coke oven, have simple in structure, locking setting range is large, applicable performance good, locking reliability is high, the advantage that can not leak coal in the process of tamping briquette.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (front view);
Fig. 2 is working process schematic diagram of the present utility model;
Fig. 3 is that the A-A of Fig. 2 is to sectional view;
Fig. 4 is that the B-B of Fig. 1 is to sectional view.
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment
As Fig. 1, 2, 3, shown in 4, a kind of tamping coking oven side filling coal car front apron opens and closes and locking gear, comprise: the front apron 1 that forms Tamping coal runner, fixedly wallboard 3, movable wallboard 4, and front apron opens and closes oil cylinder 2, described front apron opens and closes oil cylinder 2 one end hinge joints on fixing wallboard 3, one end hinge joint is on front apron 1 in addition, on front apron 1, be welded with strongback 5, on movable wallboard 4, be welded with locking cylinder bracket 8, on locking cylinder bracket 8, use bolt 10, nut 11, packing ring 12 fixed latch oil cylinders 7, the piston rod head of locking oil cylinder 7 is threaded with wedge-shaped bolt axle 9, on movable wallboard 4, both sides corresponding to described strongback 5 are welded with positioning seat 6, described front apron 1 by front grillage 13 and tiltedly frame 14 form, two oblique framves 14 are welded on respectively front grillage 13 near movable wallboard 4 and the fixing side of wallboard 3.
Working process of the present utility model:
When front apron 1 is closed, start the front apron switching oil cylinder 2 of hinge joint on fixing wallboard 3, the rotation of driving front apron, when front apron needs to lock after forwarding on movable wallboard 3, because two positioning seats 6 on movable wallboard 4 are clipped in the middle the strongback 5 being fixed on front apron 1, when locking oil cylinder 7 stretches out, in the circular hole that wedge-shaped bolt axle 9 is inserted on positioning seat 6 and strongback 5, front apron is locked on movable wallboard.Because wedge-shaped bolt 9 has, lead and Accommodation, even positioning round orifice not exclusively overlaps on strongback 5 and positioning seat 6, also can insert by adjustment, thereby realize the positive lock of front apron.
When front apron need to be opened, first utilize the oil cylinder of front apron locking gear that wedge is put forward, locking device is removed, then by front apron Unscrew.
The utility model is applied in single removable wall side coal car, the activity form of front apron can adopt ripe rotary switching mode, and utilize the mode that increases oblique frame on front apron, coal dust gear, in coal bin inner side, has effectively been solved to the problem that front apron leaks coal.In the situation of coalingging normally, close front apron, utilize the vertical movement of locking oil cylinder, together with wedge-shaped bolt axle, front apron being locked in removable wall.Because this locking device structure is simple, setting range is large, less demanding to the relative position of front apron and movable wallboard, can arrange that many groups are worked simultaneously on movable wallboard, and reliability is high.Can complete reliable locking, possess again adjustment function, improve the production efficiency of coke oven for iron, reduce operation and maintenance cost.Meanwhile, solve single removable wall side coal car front apron and opened and closed the problem that can only adopt parallel movable.
