Abstract
The invention discloses a kind of simple in construction, the attachment means that easy to loading and unloading and reliability is higher.The present invention includes binaural connector and the round pin coordinated with binaural connector, ears on described binaural connector are provided with reducing pin-and-hole, described round pin is reducing round pin, and the head and tail of this reducing round pin is all embedded in binaural connector, on the reducing round pin that Type B pin is inserted in binaural connector.Owing to the present invention using reducing round pin, adapt to the binaural connector of multiple diameter, when, after the reducing round pin being equipped with plurality of specifications, only changing the reducing round pin of different size.The head and tail using reducing round pin is all embedded in binaural connector, the structure on reducing round pin that Type B pin is inserted in binaural connector, makes reducing round pin will not slip after drawing in motor process and causes damage with support friction, and the reliability of work is further enhanced.
Description
Technical field
The present invention relates to the attachment means slipped after a kind of underground coal mine fully-mechanized mining working surface hydraulic support draws.
Background technology
Underground coal mine is combined and is adopted low caving coal equipment, is made up of forward scraper transporter, hydraulic support and rear portion scratch board conveyor.The reach of rear portion transporter is slipped jack and is connected by slipping after drawing after soft connection device draws with support, slip the flexible reach completing rear portion transporter of jack by support after drawing.Rear monaural connector by bearing pin with after slip and be connected, round-link chain is fixed on monaural connector by monaural connector by two bolts, pressing plate, round-link chain is fixed on above binaural connector with bolt, pressing plate by the other end of round-link chain equally, and the other end of binaural connector is connected by bearing pin and the jack that slips after drawing.Owing to slipping the difference of jack engaging lug pin-and-hole diameter after unit-frame type does not draws, adapted is fixed diameter pin, so, each frame type need to be equipped with a kind of engaging lug, can not be not general between unit-frame type.Therefore, bring very big inconvenience to dynamo-electric accessory management and charge and discharge operations.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the attachment means that easy to loading and unloading and reliability is higher.
The technical scheme is that the present invention includes binaural connector and the round pin coordinated with binaural connector, ears on described binaural connector are provided with reducing pin-and-hole, described round pin is reducing round pin, the head and tail of this reducing round pin is all embedded in binaural connector, on the reducing round pin that Type B pin is inserted in binaural connector.
Owing to the present invention using reducing round pin, adapt to the binaural connector of multiple diameter, when after the reducing round pin being equipped with plurality of specifications, only need to change the reducing round pin of different size, without changing binaural connector, not only simplify structure, saved manufacturing cost, operate when changing not unit-frame type the most very convenient.The head and tail using reducing round pin is all embedded in binaural connector, the structure on reducing round pin that Type B pin is inserted in binaural connector, making reducing round pin will not slip after drawing in motor process and cause damage with support friction, therefore, the reliability of work is further enhanced.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of Fig. 1.
Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but does not constitute any limitation of the invention.Shown in Fig. 1 and Fig. 2, the present invention includes binaural connector 1 and the round pin coordinated with binaural connector 1, ears on described binaural connector 1 are provided with reducing pin-and-hole, described round pin is reducing round pin 2, the head and tail of this reducing round pin 2 is all embedded in binaural connector 1, and Type B pin 3 is inserted on the reducing round pin 2 in binaural connector 1.During use, hydraulic jack is connected end 4 and penetrates in reducing round pin 2, then Type B pin 3 is inserted.Reducing round pin 2 can be made into multistage, and each section of diameter difference, to adapt to change the needs of more different size frame type.
Claims (1)
1. an attachment means, including binaural connector (1) and the round pin that coordinates with binaural connector (1), it is characterized in that: the ears on described binaural connector (1) are provided with reducing pin-and-hole, described round pin is reducing round pin (2), the head and tail of this reducing round pin (2) is all embedded in binaural connector (1), and Type B pin (3) is inserted on the reducing round pin (2) in binaural connector (1).
