Abstract

A two section machine coal cutting machine mainly aims to solve technical problems of structure simplification and improvement of stress state etc. and adopts the following technical proposal: the frame of the coal cutting machine comprises a left frame and a right frame fixed together into integrity. The utility model is suitable for working face coal cutting of both advanced common mining and economical fully-mechanized mining.

Description

The coal-winning machine of two sections fuselages

Technical field:

The utility model relates to a kind of coal-winning machine, particularly a kind of segmented fuselage coal-winning machine.

Background technology:

Existing high-grade conventional mining and economic combining are adopted the coal-winning machine of use, mostly adopt three sections (left side sections, stage casing and right section) airframe structure, to adapt to the coal mining activity environment, thereby general structure complexity, equipment making cost height, the left side of these structures, the outboard end of right fuselage all is hinged with a rocking arm, a left side, be respectively arranged with cutting drum on the right rocking arm, a left side, right rocking arm is directly driven by cutting motor, a left side, the supporting seat adjust high cylinder of right rocking arm, walking mechanism is to be installed in a left side, in or right, in on two sections fuselages, during the cut operation; the cut counter-force that the rocking arm supporting seat is subjected to; the reaction of bearing of adjust high cylinder; the traction counter-force of walking mechanism is that two sections fuselages by left fuselage and middle machine body or right fuselage and middle machine body bear; its stress is extremely unreasonable, equipment operation troubles rate height.

The utility model content:

Technical problem to be solved in the utility model provides a kind of coal-winning machine of improved two sections fuselages, and its energy simplified structure reduces equipment cost, and can improve the dependability of coal-winning machine.

The technical scheme in the invention for solving the above technical problem is: coal-winning machine includes fuselage, rocking arm, cutting drum, adjust high cylinder, walking mechanism, two rocking arms are arranged on the fuselage both sides; rocking arm one end is hinged on fuselage; the other end is provided with cutting drum; rocking arm, cutting drum and walking mechanism are connected with transmission mechanism respectively; be characterized in fuselage and two sections compositions of right fuselage of coal-winning machine, the fixedly connected one that is of left and right fuselage.

The utility model adopts two sections fuselages, simplify the coal-winning machine structure, reduce equipment cost, the traction counter-force of the cut counter-force that its rocking arm supporting seat is subjected to, the reaction of bearing of adjust high cylinder, walking mechanism is born by a box structure body of left fuselage or right fuselage, its stress is obviously improved, equipment operation event rate reduces, thereby improves the dependability of coal-winning machine.

The specific embodiment:

Coal-winning machine with reference to Fig. 1,2, two sections fuselages includes composition members such as left fuselage 1, right fuselage 2, two rocking arms 3, two cutting drums 3, adjust high cylinder 4 and walking mechanism 5, wherein:

Left side fuselage 1, it is a box component, each matching component in order to the carrying coal-winning machine, the end face 11 of left side fuselage 1 and the 1 ' butt joint of right fuselage is a plane, on this plane, be laid with one group of through hole 120 and pin-and-hole 140, each Kong Jun is laid in the nearly periphery place (as shown in Figure 6) of end face 11, be respectively arranged with the recess hole 130 of location in the both sides, nearly middle part of end face 11, marginal edge at the corresponding bolts that stretch through in end face 11 inboards of left fuselage 1, be equipped with inner groovy 121,121 ' (as Fig. 5), for the space that bolt stretches through and the operation of degree of tightness nut is required;

Right fuselage 1 ' also is a box component, and structures such as its end face 11 ', through hole 120 ', pin-and-hole 140 ', recess hole 130 ', inner groovy 121 ' are all identical with left fuselage 1 ' corresponding position structure;

A left side, right fuselage 1,1 ' end face 11, in 11 ' when butt joint, is (as Fig. 3,4), at inner groovy 130,130 ' the mid-locating piece 13 (as Fig. 5) that is provided with, the size of locating piece 13 and quantity can be by end faces 11,11 ' size and deciding (Fig. 6 represents to have two locating pieces), and while installing and locating pin 14 in each pin-and-hole 140, the setting of locating piece 13 and alignment pin 14, remove and guarantee biend 11,11 ' accurately engages, and can improve a left side, the stress of right fuselage, on a left side, right fuselage 1, behind the 1 ' joint, at inner groovy 121,121 ' each through hole 120 of locating, 120 ' wears clamping bolt 12 or hydraulic bolt 12 ', makes a left side, right fuselage 1,1 ' the fixedly connected integral body that is;

Two rocking arms 2, the one end is hinged on left and right fuselage 1 respectively, 1 ' outboard end is provided with adjust high cylinder 4 in addition, adjust high cylinder 4 is controlled two rocking arms 3 respectively, make the left and right relatively fuselage of cutting drum 31,1 ' high and low position can be adjusted at the operation desired position, be laid with walking mechanism, all supporting transmission mechanism and the power (as motor, oil pump oil motor etc.) of being provided with of cutting drum 3, adjust high cylinder 4 and walking mechanism on the left and right fuselage 1,1 '.
