Abstract
The utility model discloses a connection device, which is simple in structure, convenient to assemble and disassemble and high in reliability. The connection device comprises a double-lug connection part and a round pin matched with the double-lug connection part, double lugs of the double-lug connection part are provided with diameter-changing pin holes, the round pin is a diameter-changing round pin, the head and the tail of the diameter-changing round pin are both embedded into the double-lug connection part, and a B-shaped pin is inserted on the diameter-changing round pin arranged in the double-lug connection part. Due to the diameter-changing round pin, the connection device can be applied to double-lug connection part of various diameters. When diameter-changing round pins of various specifications are arranged, users only need to replace the diameter-changing round pins of various specifications. The structure that the head and the tail of the diameter-changing round pin are both embedded into the double-lug connection part, and the B-shaped pin is inserted on the diameter-changing round pin arranged in the double-lug connection part prevents the diameter-changing round pin form being damaged by friction with a support in the pull slide motion and further improves working reliability.
Description
Technical field
The utility model relates to the linkage that fully-mechanized mining working surface hydraulic support draws the back to slip under a kind of coal mine.
Background technology
Combine under the coal mine and adopt low caving coal equipment, form by anterior scratch board conveyor, hydraulic support and rear portion scratch board conveyor.The reach of rear portion transporter is by drawing back slide soft connection device and support to draw back slide jack to be connected, and the stretching of jack of slipping after drawing by support accomplished the reach of rear portion transporter.Back monaural connector slips with the back through bearing pin and is connected; The monaural connector is fixed on round-link chain on the monaural connector through two bolts, pressing plate; The other end of round-link chain is fixed on round-link chain above the binaural connector with bolt, pressing plate equally, and the other end of binaural connector is connected with drawing back slide jack through bearing pin.Because the unit-frame type does not draw the back to slip the difference of jack engaging lug pin-and-hole diameter, adapted be the fixed diameter pin, so each frame type need be equipped with a kind of engaging lug, can not be not general between the unit-frame type.Therefore, bring very big inconvenience for dynamo-electric accessory management and charge and discharge operations.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, easy to loading and unloading and linkage that reliability is higher.
The technical scheme of the utility model is: the utility model comprises binaural connector and the round pin that cooperates with binaural connector; Ears on the said binaural connector are provided with the reducing pin-and-hole; Said round pin is the reducing round pin; The head and tail of this reducing round pin all is embedded in the binaural connector, and the Type B pin is inserted on the reducing round pin in the binaural connector.
Owing to adopt the reducing round pin in the utility model; The binaural connector that can adapt to multiple diameter; Behind the reducing round pin that is equipped with plurality of specifications, the reducing round pin that only needs to change different size gets final product, and need not change binaural connector; Not only simplify the structure, practiced thrift manufacturing cost, operation is also very convenient when changing not the unit-frame type.Adopt the head and tail of reducing round pin all to be embedded in the binaural connector; The Type B pin is inserted in the structure on the reducing round pin in the binaural connector; Make the reducing round pin can in drawing back slide motion process, not cause damage with the support friction, therefore, the reliability of work is further enhanced.

Fig. 2 is the STRUCTURE DECOMPOSITION sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain, but do not constitute any restriction the utility model.Illustrated in figures 1 and 2; The utility model comprises binaural connector 1 and the round pin that cooperates with binaural connector 1; Ears on the said binaural connector 1 are provided with the reducing pin-and-hole; Said round pin is a reducing round pin 2, and the head and tail of this reducing round pin 2 all is embedded in the binaural connector 1, and Type B pin 3 is inserted on the reducing round pin 2 in the binaural connector 1.During use, hydraulic jack link 4 is penetrated in the reducing round pin 2, then 3 insertions of Type B pin are got final product.Reducing round pin 2 can be made into multistage, and each section diameter difference is to adapt to the needs of the more different size framves of replacing type.
