Abstract
The utility model discloses a central hinge device for connecting a frame. The central hinge device consists of a vertical hinge body and a horizontal hinge body which are welded together; a hinge pin shaft is inserted in the vertical hinge body, and two ends of the hinge pin shaft are provided with pin shaft glands; two ends of the vertical hinge body are respectively provided with a copper bush serving as a sliding bearing; the horizontal hinge body is inserted into a shaft sleeve of a front frame; two ends of the horizontal hinge body are provided with copper bushes serving as sliding bearings; and the tails of the horizontal hinge body are provided with hinge glands. The central hinge device is simple in structure, high in load bearing strength, reliable in working performance and convenient to install and maintain, and is particularly suitable for running and working in narrow places such as underground tunnels and rugged road surfaces.
Description
Technical field
The utility model relates to a kind of vehicle frame bonded assembly central authorities articulated mounting that is used for, and belongs to the articulated frame technical field of construction machinery and equipment, mining machinery.
Background technology
Articulated engineer machinery mostly adopts articulated structure to be connected front vehicle frame and back vehicle frame with the mine vehicle, and vehicle rotates around hinged center, realizes turning to of complete machine.It is good to have a crossing ability with respect to unit frame, and characteristics such as turn radius is little, maneuverability are used in construction machinery and equipment and mining machinery in a large number.Usually the front and back vehicle frame of articulated vehicle is connected by the hinging pin shaft in the articulated mounting; Oscillating bearing or spacer by being sleeved on the hinging pin shaft come carry-over moment to realize turning to of complete machine; The axial restraint reliability of this oscillating bearing or spacer is relatively poor; Cost is high, and assembling is difficult, can not adapt to market and user's demand fully.
The utility model content
It is a kind of simple in structure that the purpose of the utility model provides, and loading strength is high, workability is reliable and a kind of easily vehicle frame bonded assembly central authorities articulated mounting that is used for of installation and maintenance.
The technical scheme of the utility model is: this articulated mounting is made up of the vertical articulated body and the horizontally hinged body of weld together; Be coated with hinging pin shaft in the said vertical articulated body; At its two ends the bearing pin gland is housed, a copper sheathing that uses as plain bearing respectively is housed at its two; Said horizontally hinged body is installed in the axle sleeve of front vehicle frame, and the copper sheathing that uses as plain bearing is housed at horizontally hinged body two ends, and its end is equipped with hinged gland.
The middle part of said vertical articulated body is provided with the alemite that is used for to the copper sheathing grease up.
The axle sleeve of said front vehicle frame is provided with the alemite that is used for to the copper sheathing grease up at horizontal articulated body two ends.
On the front vehicle frame below the hinged gland, be equipped with two front and back vehicle frame vertical direction swing carried out spacing limiting stopper.Prevent vehicle frame on rugged road owing to the swing the excessive crank that causes of amplitude tumble.
When the piston rod that turns to oil cylinder stretched out, the vertical articulated body of central articulated mounting just rotated around hinging pin shaft during use, and the horizontally hinged body with vertical articulated body welding is delivered to drive torque on the axle sleeve of front vehicle frame simultaneously, front vehicle frame is accomplished turned to.
The advantage of the utility model: this central authorities' articulated mounting adopts two-axis hinge device to realize the connection of front and back vehicle frame; Simple in structure; Loading strength is high, workability is reliable and installation and maintenance are convenient, suits especially on narrow place such as underworkings and rugged road surface, to go and operation.

The specific embodiment
Embodiment
Referring to accompanying drawing:
This articulated mounting is welded by vertical articulated body 4 and horizontally hinged body 6, in vertical articulated body 4, is being coated with hinging pin shaft 8, bearing pin gland 3 is housed at the two ends of vertical articulated body prevents hinging pin shaft play about in the of 8; Copper sheathing 7 is equipped with at vertical articulated body two ends; Be provided with the alemite 16 that is used for to copper sheathing 7 grease ups at vertical articulated body middle part; To reduce the friction of motion resistance; Be provided with symmetric arrangement in vertical articulated body lower end two turn to oil cylinder 12, turn to oil cylinder one end to link to each other with the back vehicle frame, and an end links to each other through bearing pin 5 with vertical articulated body lower end.
Horizontally hinged body 6 is installed in the axle sleeve 11 on the front vehicle frame, and copper sheathing 2 is equipped with at horizontally hinged body 6 two ends, at the end of horizontally hinged body the hinged gland 1 of two wing shapes of picture is housed, and it is carried out horizontal axis fix.On axle sleeve 11, be provided with the alemite 9 that is used for to the copper sheathing grease up,, two swing limiting stoppers 15 be housed on front vehicle frame 10, be arranged symmetrically in the below of two wings of hinged gland to reduce the friction of motion resistance.
During installation hinged seat 14 on the vehicle frame of back is grasped central articulated mounting with following hinged seat 13
During use; When the piston rod that turns to oil cylinder stretches out; The vertical articulated body of central authorities' articulated mounting just rotates around hinging pin shaft 8, and the horizontally hinged body 6 with vertical articulated body 4 welding is delivered to drive torque on the axle sleeve 11 of front vehicle frame simultaneously, front vehicle frame 10 is accomplished turned to; When vehicle ' arrives rugged road surface; The front and back vehicle frame is swung in vertical direction; Because symmetric arrangement has two swing limiting stoppers 15 on front vehicle frame; Hinged gland 1 in the swing is carried out spacing, prevent vehicle frame on rugged road since the excessive crank of swinging that causes of amplitude tumble.
