Abstract
The utility model discloses a hydraulic support thrust gear, which comprises a thrust bar body, wherein the two ends of the thrust bar body are respectively equipped with a connecting head and a thrust head, the thrust bar body is a long and narrow box-shaped bar body and comprises an upper plate, a lower plate and a side plate, a middle rib plate is arranged in a middle cavity lengthways, and a plurality of support rib plates are fixedly connected between the upper plate and the lower plate along the transverse direction in space. One end of the long and narrow box-shaped bar body is equipped with a connecting ear plate which is formed into an integrated structure with the upper plate and the lower plate, and the connecting ear plate is connected with the connecting head through a stress pin. The hydraulic support thrust gear has the advantages that the thrust bar body is the long and narrow box-shaped bar body, thereby meeting the demands of structural arrangement and discharging float coal. The connecting ear plate is connected with the connecting head through the stress pin, and the stress pin is broken when the shock is overload, thereby being capable of protecting the thrust bar body and the connecting head.
Description
Technical field
The utility model relates to hydraulic support, especially relates to the hydraulic support thrust gear that a kind of hydraulic support is connected with transporter.
Background technology
Thrust gear is a principal organ that finishes the hydraulic support function, is used to pass drag conveyor and draws move support, the propelling of the face of finishing the work.It simultaneously is again the load bearing component of lifting end jack action.This just make thrust gear bear draw, carrying lateral force in the pressure; Because be subjected to the requirement of structural limitations and row's float coal, pusher rod must be narrow structure, bears very big alternating force on small bore is long-pending; Require the back thrust gear simultaneously and pass the compliance that jack piston rod is connected and is connected with transporter.
The utility model content
The purpose of this utility model is to provide a kind of reliability height, row's float coal hydraulic support thrust gear effective, easy to connect.
For achieving the above object, the utility model can be taked following technical proposals:
Hydraulic support thrust gear described in the utility model, comprise the passing body of rod, described passing body of rod two ends are respectively arranged with connector and push-and-pull head, the described passing body of rod is the long and narrow box-shaped body of rod, constitute by upper plate, lower plate and side plate, be vertically arranged with middle gusset in the lumen, perpendicular separation is fixed with a plurality of bearing ribs between upper plate, lower plate.
The described long and narrow box-shaped body of rod one end is provided with upper plate, lower plate are structure as a whole and is connected otic placode, and described connection otic placode is connected with described connector by the stress pin; Described push-and-pull head is vertical push-and-pull head, is provided with projection in described vertical push-and-pull crown portion and side.
Described connection otic placode is a wrapper sheet formula otic placode.
Advantage of the present utility model is that the described passing body of rod is set to the long and narrow box-shaped body of rod, the described long and narrow box-shaped body of rod is made of upper plate, lower plate and side plate, be vertically arranged with middle gusset in the lumen, perpendicular separation is fixed with a plurality of bearing ribs between upper plate, lower plate, satisfies the requirement of structural configuration and row's float coal; The described long and narrow box-shaped body of rod one end is provided with upper plate, lower plate are structure as a whole and is connected otic placode, and described connection otic placode is connected with described connector by the stress pin, and destroyed protection of stress pin passed the body of rod and connector when impact acceleration; Described push-and-pull head is vertical push-and-pull head, solves the installation question in the confined space, is provided with projection in described vertical push-and-pull crown portion and side simultaneously, can play the guiding role to pushrod movement, discharges float coal easily; Described connection otic placode is a wrapper sheet formula otic placode, can strengthen junction rigidity and anti-twisting property by wrapper sheet.
