Abstract
The present invention relates to a hydraulic flat-moving type automatic safety door which is suitable for a passageway of a vertical shaft hoisting cage for coal mines. The automatic safety door is composed of two door bodies, wherein each door body controls the passageway of the cage. A corresponding drive mechanism drives the door body to move right and left along an open type roller path. The open type roller path is arranged on three upright posts which are arranged in parallel, and is formed by abutting the left roller path and the right roller path. A roller train is arranged in each open type roller path to roll backwards and forwards in the open type roller path. The roller trains, pin rows and the door bodies are connected into a whole. A transmission mechanism which is composed of a pin gear and a hydraulic motor is used, the pin gear is directly driven by the hydraulic motor, and the pin gear drives the pin rows. The automatic safety door has the advantages that the transmission system is greatly simplified, the transmission carrying capacity is large, and the transmission system is stable to run; the right roller path can be opened, which is favorable to the unloading of long materials, and the function is perfect; the motive power is single; the overall system has the characteristics of safety, reliability, simple structure, light weight, convenient operation and wide practicability.
Description
Technical field
The present invention relates to a kind of hydraulic flatly moving type automatic safety door, be particularly useful for the import and export of coal mine shaft lining winding cage.
Background technology
In the coal mine shaft lining hoisting way, the hoisting container cage is in operation or when not stopping putting in place, need utilize safety door that well head is up and down protected, and crashes in the pit shaft to prevent that personnel, mine car or other objects are accidental, causes unnecessary personnel and property loss.Present most mine safety door all adopts dynamical type, can not artificially arbitrarily open.The type of dynamical type safety door is a lot, wherein commonly used mainly contains two kinds: a kind of is pneumatic or the slidingtype safety door that surges, and the door running body of this safety door adopts and slides, and connects slideway one end with a cylinder or hydraulic cylinder, the other end is fixed, and tilts a body is freely glided along slideway by slideway.The shortcoming of this safety door is a body owing to be freely to glide, and therefore the speed that glides is subjected to the influence of slideway workmanship, environment etc.Workmanship encircles well, variations in temperature (ice up in winter etc.), lubricating grease concentration etc. all can make a body motion actual speed and design speed have greater difference.If speed is too fast, the door body puts in place the generation bounce-back, and the door body can not be in time; If speed is too slow, will increase the stop time, both of these case all is unfavorable for the lifting operation of mine.In addition, when transferring long material, how the slidingtype safety door need dismantle a body, wastes time and energy, and influences the lifting time.Another kind is electronic or the chain type safety door that surges, and this body links to each other with drive unit by bush(ing) chain, after the employing hydraulic lock puts safe every body in place, has auto-lock function, helps security improvement.But linked transmission needs chain tightener, and safeguards inconvenience, and reliability is low.
Except that top two kinds, also have hydraulic jack parallel-moving type, connecting rod to open and close folding gate-type, lattice door linear electric motors left and right sides parallel-moving type safety door etc.Hydraulic jack parallel-moving type safety door utilizes the piston rod end of hydraulic jack hinged with the door body, and a cylinder body and a heel post are fixed.When hydraulic cylinder piston rod was flexible, the door body can move back and forth in the slideway of level, realized the opening and closing action of door.The shortcoming of this structure is that the stroke of oil cylinder is oversize, and the frequent stretching motion of oil cylinder causes cylinder seal to destroy and leakage of oil easily.It is big that above-mentioned in addition safety door all exists safety door weight, and fault rate is higher, stops the loaded vehicle weak effect, complex structure, the problem of inconvenient maintenance.
Summary of the invention
In view of the problem that prior art exists, the purpose of this invention is to provide that a kind of transmission is simple, lightweight construction, reliability height, the effective hydraulic flatly moving type automatic safety door of keeping off a car.
The technical solution adopted for the present invention to solve the technical problems is: be provided with two groups of open type raceways on three left columns that are arranged in parallel, central post and right columns, every group of open type raceway is provided with at interval mouth to mouth by two channel-section steels and forms, every group of open type raceway is by rolling left and the butt joint of right raceway forms, it is hinged that first right-hand member and right column and oil cylinder are rolled in the right side, the left end cantilever, can open along pin joint, whenever arrange and be respectively equipped with the roller set that can roll back and forth in the formula raceway within it, roller set and pin row and door body connect as one; Central post is provided with the support that supports the open type raceway, and the transmission mechanism symmetry of being made up of pin gear and hydraulic motor is located on the support, and pin gear directly connects with hydraulic motor, and meshes with pin row; Drive hydraulic motor by Hydraulic Power Transmission System, the fluid motor-driven pin gear, pin gear drives pin row and makes a body translation, utilizes oil cylinder to open right raceway; The inboard of left and right pillar is provided with the travel switch of control gate body position and prevents a cushion pad of body collision.
The roller of described each roller set is dumbbell shaped, and the connecting rod at roller middle part is provided with junction plate, and roller two symmetry also is provided with the cambered surface that matches with open type raceway grooves on two sides; The hinged oil cylinder of described right raceway right-hand member be located on the right column or be located at roll left on; Described by the open type raceway that rolls left and the butt joint of right raceway forms, two both ends of rolling left are provided with respectively and make it be fixed on bolt on left column and the central post, right raceway is provided with the joint that rolls left and can makes right raceway upwards lift impregnable slit, and right raceway right-hand member and right column hinged place are provided with bearing pin.Described pin row vertically is located at by the below of rolling left and right raceway docks the open type raceway that forms, and a side of pin row is connected with the junction plate of roller set, and opposite side is connected with a door body with pin by suspension rod, is located at the pin gear that meshes with pin row on the support and is horizontally disposed with; Described pin row level is located at by the top of rolling left and right raceway docks the open type raceway that forms, direct and pin gear meshes, the pin row below connects roller set by junction plate, the below of roller set is connected with the door body by junction plate, suspension rod and pin, is located at vertical setting of pin gear of meshing with pin row on the support.
Beneficial effect: a kind of hydraulic flatly moving type automatic safety door of the present invention, be best suited for the import and export of coal mine shaft lining winding cage, adopt the pin gear transmission mechanism, simplified transmission system greatly; Pin gear and pin row Transmission bearing are big, operate steadily; Use the fluid motor-driven pin gear, thereby drive pin row and door body, open the semi-open type raceway material that is beneficial to down lengthen, complete function with oil cylinder; Use hydraulic drive, can realize the translation of safety door and open two actions of raceway, power is single; Whole system is safe and reliable, and is simple in structure, in light weight, easy to operate, almost can be non-maintaining, be specially adapted to the occasion of the many trickles in down-hole, and have practicality widely.
