Abstract
Light support top coal caving working face lower end support equipment belongs to the technical field of mine support equipment, and is used for the lower end support of an underground light support top coal caving working face. The technical scheme is characterized in that: the lower end support equipment comprises four support pillars, top beams, two passing top platforms and two passing tops, wherein the support pillars, the passing top platforms and the passing tops are arranged at two sides of a loading machine equally, bottoms of the support pillars are connected into a whole by iron plates, tops of the two support pillars at each side of the loading machine are connected by the top beam, the iron plates at the bottoms of the support pillars are arranged above the passing top platforms, one ends of the passing top platforms are connected with the passing tops, and the passing tops are fixedly connected with side surfaces of the loading machine. According to the lower end support equipment of the utility model, moves of the support equipment can be completed by retracting of the passing tops at the two sides of the loading machine; then self-moves of the loading machine can be completed by extending of the passing tops at the two sides of the loading machine after the support equipment rises actually. By adopting the lower end support equipment of the utility model, production efficiency of the light support top coal caving working face can be raised, support and sleeve links can be reduced, and labor intensity of workers can be reduced obviously.
Description
Technical field
The utility model relates to a kind of mine laneway light sublevel caving face lower end support apparatus, belongs to the mine support equipment technical field.
Background technology
In Coal Production, light sublevel caving face lower end supporting metal hinge top beam in the tunnel of using the metal arch bracket support in down-hole cooperates the monomer column supporting roof to trichopore, and the same metal hinge top beam that uses cooperates monomer column combined supporting top board to trichopore in the anchor net tunnel.Using metal hinge top beam to cooperate in the process of monomer column supporting roof, drop in beam is played the supporting of post, trichopore and returned to remove all needs to stop the elevating conveyor operation, and then operates.Simultaneously, lower end is because the space is limited, in carrying, return that to remove in the operating process be the territory, accident-prone area.The on-the-spot lower end support apparatus that uses in down-hole has certain influence to the regular work cycle of light sublevel caving face at present, and during operation, labor strength is bigger, and the lower end environment also constitutes certain threat to workman's safety.Therefore be necessary to design a kind of new lower end support apparatus, to satisfy the demand of producing.
The utility model content
Technical problem to be solved in the utility model provides a kind of production efficiency that can reduce lower end support apparatus and cover nest link, promote light sublevel caving face, reduces the light sublevel caving face lower end support apparatus of working strength of workers.
The technical scheme that solves the problems of the technologies described above is:
A kind of light sublevel caving face lower end support apparatus, it is by the support huge pillar, back timber, pass roof panel, the passing holder is formed, the support huge pillar is four, the both sides of elevating conveyor are placed in, two of every sides, pass roof panel and pass holder and respectively be two, the both sides of elevating conveyor are placed in, four big column bottoms of support are connected as one by iron plate, the top of two support huge pillars of the every side of elevating conveyor is connected by back timber, the bottom iron plate of support huge pillar is placed on passes the roof panel top, and an end of passing roof panel is connected with the passing holder, passes holder and fixedlys connected with the elevating conveyor side.
Above-mentioned light sublevel caving face lower end support apparatus, the iron plate of described four big column bottoms of support contacts with the elevating conveyor plane parallel.
Above-mentioned light sublevel caving face lower end support apparatus, the big end of the passing roof panel of described elevating conveyor both sides and elevating conveyor, form one.
Adopt the light sublevel caving face lower end support apparatus of this structure, when need are mobile, fall four posts, pass holder by the elevating conveyor both sides and regain, finish moving of support apparatus; After support apparatus rises in fact, pass stretching of holder by the elevating conveyor both sides and finish moving certainly of elevating conveyor.By enforcement of the present utility model, the production efficiency of light sublevel caving face gets a promotion, and has reduced supporting and cover nest link, and working strength of workers obviously reduces.
Description of drawings
Fig. 1 is a schematic top plan view of the present utility model;
Fig. 2 is a schematic side view of the present utility model.
Mark is as follows among the figure: support huge pillar 1, back timber 2, passing roof panel 3, passing holder 4, iron plate 5, elevating conveyor 6, first pack support 7.
The specific embodiment
The utility model is made up of support huge pillar 1, back timber 2, passing roof panel 3, passing holder 4.
Show among the figure that support huge pillar 1 is four, the both sides of the elevating conveyor 6 that is placed in, two of every sides, four support huge pillar 1 bottoms are connected as one by iron plate 5, and iron plate 5 contacts with elevating conveyor 6 plane parallel, and the top of two support huge pillars 1 of every side is connected by back timber 2.At elevating conveyor 6 and the utility model one side is first pack support 7.
Passing roof panel 3 and passing holder 4 is two respectively, the both sides of the elevating conveyor 6 that is placed in, and every side has one to pass roof panel 3 and a passing holder 4.Pass roof panel 3 and form one with the 6 big ends of elevating conveyor, the bottom iron plate 5 of support huge pillar 1 is placed on passes roof panel 3 tops.An end of passing roof panel 3 is connected with passing holder 4, passes holder 4 and fixedlys connected with elevating conveyor 6 sides, finishes moving of support apparatus and elevating conveyor 6 by passing stretching of holder 4.
Move and the work plane of this light sublevel caving face lower end support apparatus put down support gently and moved equally, needs to fall four posts when mobile, passes the holder withdrawal by the elevating conveyor both sides, finishes the mobile of light sublevel caving face lower end support apparatus; Light sublevel caving face lower end support apparatus is finished moving certainly of elevating conveyor by stretching of elevating conveyor both sides holder after rising in fact.
After the utility model is implemented, reduce lower end support apparatus, cover nest link, improved dynamo-electric operational efficiency, improved regular work cycle rate, improved light sublevel caving face per unit area yield efficient.An embodiment of the present utility model shows that after light sublevel caving face lower end support apparatus was implemented, the production efficiency of light sublevel caving face had original per tour three cuttves to bring up to per tour four blade, and lower end support apparatus operating personnel reduce to two people by original per tour four-player.The enforcement of light sublevel caving face lower end support apparatus can be created and imitate more than 5,000,000 yuan in year.
