Abstract
The utility model discloses a seal connecting device which comprises an end cap, a fixed seat and a bearing block. A rotating shaft is arranged in the bearing block, the bearing block is detachably connected with the fixed seat, the end cap is arranged at the front end of the bearing block, a portion matched with the end cap is arranged on the front end face of the bearing block, bearings are arranged on two inner sides of the bearing block, sealing gaskets are arranged between contact surfaces of the fixed seat and the bearing block, and sealing rings are arranged at joints of the rotating shaft, the bearing block and the end cap. The seal connecting device overcomes the shortcomings of the prior art, a design mechanism is reasonable, a connecting shaft of a motor and a roller is provided with a sealing structure, seal and isolation of air inside and outside an air shaft are ensured, and a lifting system is started to slowly lift when rescue or shaft maintenance is needed.
Description
Technical field
The utility model relates to seal connection technical field, specifically belongs to a kind of seal connection that passes body of wall for rotatingshaft.
Background technique
The mine of existing underground mining is equipped with return air shaft, need to for the ventilation of mine.The top of vertical return air shaft is equipped with explosion proof door, and closely the pit shaft side on surface is provided with blower fan and air channel.Under the powerful pump drainage of blower fan and the cooperation of other equipment, ozone enters down-hole by downcast, and each need to use the place of wind, then is pooled to return air shaft through wind path separately, through blower fan and air channel, discharges.Common explosion proof door band counterweight balance piece, main body to explosion proof door applies lifting force, ventilating shaft inside is negative pressure state under the work of blower fan, and the main body of the external gas pressure and explosion proof door is slightly larger than the lifting force of counterweight balance piece from doubling force, keeps explosion proof door normally to close.After down-hole accident blast occurs or blower fan out of service, negative pressure disappears, the main body of explosion proof door rises to certain altitude under the lifting of counterweight balance piece, makes explosion proof door in opening state, the interim natural ventilation of mine under maintenance accident condition.
The another one function of return air shaft is emergency escape channel, in return air shaft, has arranged solar, when the down-hole accident of blasting, when personnel in the pit cannot get back to ground from down-hole by normal mode, can crawl into ground from the solar of return air shaft; In addition,, along with the development of mining industry in recent years, some special pipelines, as cooling, waste pipe etc., are also arranged connecting downhole and ground once in a while from return air shaft.
Along with the development of mining industry, the degree of depth of mine is more and more darker, if in case of emergency escape personnel crawls into ground and is difficult to from down-hole, sick and wounded if escape personnel has, creeping escape hardly may; In addition, if there is pipeline in pit shaft, its service work difficulty of creeping on solar is also very large.For this reason, in return air shaft, need to arrange a kind of elevator system, overcome the above problems.Yet, composition of air in return air shaft is very complicated, conventionally carrying the foreign material such as gas, coal dust secretly, motor and lifting means are set under return air shaft inside, anti-riot door will be likely because spark causes gas explosion, even employing anti-explosion motor, still there is the potential safety hazard setting off an explosion in its related facility under high-risk environment; In addition, be subject to the condition restriction of overhaul of the equipments requirement, it is also unallowed that motor and drive unit are set herein.Just because of this, also in return air shaft, do not arrange service hoisting equipment at present, above problem still exists.
Model utility content
The purpose of this utility model has been to provide a kind of seal connection, has overcome the deficiencies in the prior art, and design organization is reasonable, the coupling shaft of motor and cylinder adopts sealing configuration, guarantee the seal isolation of ventilating shaft inner air and outer air, when needs rescue or pit shaft maintenance, enable elevator system and promote at a slow speed.
The technical solution adopted in the utility model is as follows:
A kind of seal connection, described connection set, comprise end cap, fixed base and bearing support, rotatingshaft is arranged in bearing support, and bearing support and fixed base removably connect, and end cap is arranged at bearing support front end, bearing support front-end face is provided with the part coordinating with end cap, bearing is arranged at both sides in bearing support, between described fixed base and bearing support surface of contact, is provided with sealing gasket, at rotatingshaft and bearing support, end cap joint, is provided with seal ring.
Described bearing support inserts in fixed base, and fixed base and bearing support front end have the localization part cooperatively interacting, and localization part is fixedly connected with by fastening piece.
Between described fixed base and bearing support, fore-end is conical surface contact.
Described fixed base is provided with a plurality of nipple hole seats that all distribute outward, and reinforcing bar one end and hole seat are fixed, the other end and the welding of borehole wall inner concrete reinforcing bar.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model motor driving part part, outside return air shaft, adopts the axle of band sealing to be connected with cylinder, guarantees the isolation of return air shaft inner air and outer air, and thoroughly elimination may cause the potential safety hazard of gas explosion.Fixed base and bearing support removably connect, being convenient for changing while being conducive to bearing support damage; Between its fixed base and bearing support, be provided with rubber parts, can absorb vibration, and play seal action; Fitting surface between its fixed base and bearing support is taper, is conducive to dismounting and sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
