Abstract
The utility model discloses a connecting device of a pushing rod of a hydraulic support. A front push rod is connected with a rear push rod via a left pin and a right pin, the front end of the rear push rod is provided with a left connecting lug and a right connecting lug, the rear end of the front push rod is provided with a left lug mounting plate and a right lug mounting plate, the left connecting lug is connected with the left lug mounting plate via the left pin, the right connecting lug is connected with the right lug mounting plate via a right pin, a front connecting plate and a rear connecting plate which are opposite are connected between the left and right connecting lugs of the rear push rod, a stopper is arranged between the front connecting plate and the rear connecting plate, the left wall and the right wall of the stopper are respectively abutted upon ends of the left pin and the right pin, and the top end of the stopper is provided with a fastening ring. The connecting device adopts the double-lug connecting structure to mount the connecting pins from the middle to two sides, and is convenient in mounting and dismounting and simple for manufacturing.
Description
Technical field
The utility model relates to hydraulic support, specifically is a kind of linkage of pusher rod of hydraulic support.
Background technology
In, in the high seam hydraulic support technical field, in order to strengthen the power of trying to stop people from fighting each other, the general driven mode that adopts the mechanism of retrodicting, thereby need to adopt long pusher structure.Because long push rod anti-bending strength is poor, dismounting difficulty in down-hole usually is designed to push rod two sections of front and back and connects with bearing pin.But, the present push stick connecting structure that generally adopts suitable difficulty of dismounting in the limited space of base (especially in the down-hole time), though remove pass jack after, take out also suitable difficulty of push rod.And when the push rod damage needed to change, often influence was produced.
The utility model content
The purpose of this utility model provides a kind of linkage of pusher rod of hydraulic support, adopts the ears syndeton, will connect bearing pin therefrom between to the both sides dress, easy accessibility is made simply.
The technical solution of the utility model is as follows:
The linkage of the pusher rod of hydraulic support, before be connected by left and right bearing pin between push rod and the rear push-rod, the front end of described rear push-rod has left and right engaging lug, the rear end of preceding push rod has left and right dress otic placode, left side bearing pin is connected left engaging lug with left side dress otic placode, right bearing pin is connected right engaging lug with right dress otic placode; Connecting forward and backward junction plate in opposite directions between the left and right engaging lug of described rear push-rod, be placed with limited block between the forward and backward junction plate, the left and right sides sidewall of limited block is resisted against the end of left and right bearing pin respectively, and there is clasp on the top of limited block.
There is spacing bearing pin to pass described forward and backward junction plate respectively, and the clasp of limited block, and the end of spacing bearing pin has pin-and-hole radially.
The end of described left and right bearing pin has button and pulls out the hole.
The push rod middle part is opened shelves and is of a size of 380mm before of the present utility model, forward and backward push rod adopts two left and right bearing pins of level to connect, the rear push-rod engaging lug outside is provided with limited block, make left and right bearing pin location, prevent the bearing pin play, left and right bearing pin is put into from the middle part during assembling, install toward the outside, the connection earhole of rear push-rod and the middle part of preceding push rod dress otic placode level difference is less, can pack into very easily, and with spacing bearing pin with the limited block fixed-site; When splitting out, take out limited block earlier, extract left and right bearing pin out, pull out the hole owing to have button in left and right bearing pin end, convenient finger inserts, and connecting bearing pin can take out from bracket base easily, thereby realizes the mounting or dismounting of push rod at the down-hole push rod.
The utility model adopts the ears syndeton, will connect bearing pin therefrom between to the both sides dress, easy accessibility is made simply.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the linkage of the pusher rod of hydraulic support, before be connected by left and right bearing pin 3,4 between push rod 1 and the rear push-rod 2, the end of left and right bearing pin has button and pulls out hole 5, the front end of rear push-rod has left and right engaging lug 6,7, the rear end of preceding push rod has left and right dress otic placode 8,9, and left bearing pin 3 is connected left engaging lug 6 and left side dress otic placode 8, and right bearing pin 4 is connected right engaging lug 7 and right dress otic placode 9; Be connected with forward and backward junction plate 10,11 in opposite directions between the rear push-rod 2 left and right engaging lugs 6,7, be placed with limited block 12 between the forward and backward junction plate 10,11, the left and right sides sidewall of limited block 12 is resisted against the end of left and right bearing pin 3,4 respectively, there is clasp 13 on the top of limited block, there is spacing bearing pin 14 to pass forward and backward junction plate 10,11 respectively, and the clasp 13 of limited block 12, and the end of spacing bearing pin 14 has pin-and-hole radially.
Claims (3)
1. the linkage of the pusher rod of hydraulic support, before be connected by left and right bearing pin between push rod and the rear push-rod, it is characterized in that: the front end of described rear push-rod has left and right engaging lug, the rear end of preceding push rod has left and right dress otic placode, left side bearing pin is connected left engaging lug with left side dress otic placode, right bearing pin is connected right engaging lug with right dress otic placode; Connecting forward and backward junction plate in opposite directions between the left and right engaging lug of described rear push-rod, be placed with limited block between the forward and backward junction plate, the left and right sides sidewall of limited block is resisted against the end of left and right bearing pin respectively, and there is clasp on the top of limited block.
