Abstract
The invention which belongs to the technical field of excavating apparatuses with excavating working faces for underground coal mine concretely relates to a rear stable tail wagging mechanism of an excavator to solve a problem that the fine tail adjustment of the excavator cannot be realized through rear stable mechanisms of present excavators. The rear stable tail wagging mechanism of the excavator, which comprises two rear support oil cylinders which are connected with the tail of an excavator body, is characterized in that: the piston rod end of each rear support oil cylinder is hinged to a rear support leg, the two rear support legs are respectively arranged on a left sliding shoe and a right sliding shoe, the left sliding shoe and the right sliding shoe are supported on a support base plate and can move relative to the support base plate, the support base plate is provided with a support seat which is hinged to the piston rod end of the wagging oil cylinder, and the wagging oil cylinder is hinged to the tail of the excavator body. Compared with the prior art, the rear stable tail wagging mechanism of the present invention has the advantages of flexible motion and good stability, so the problem that rear stable apparatuses of original excavators is solved, and the wagging velocity choice, and especially the turning choice of the tail of the excavator are improved.
Description
Technical field
The invention belongs to the technical field of driving face heading equipment under the coal mine, be specifically related to stablize the mechanism of wagging the tail behind a kind of development machine.
Background technology
Stabilising arrangement comprises back supporting leg and back support cylinder behind the existing development machine, the hinged back of the tailpiece of the piston rod of back support cylinder supporting leg, and the cylinder bottom end hinge joint machine afterbody of back support cylinder, by stretching the back support cylinder, back supporting leg directly is supported in ground.This structure can not realize the fine setting of development machine tail, and is subjected to structural limitations, and Area of bearing is little, poor stability.
Summary of the invention
The present invention can not realize the problem of development machine tail fine setting in order to solve stabilizing mechanism behind the existing development machine, provides the stable mechanism of wagging the tail behind a kind of development machine, the short distance swing of the stable support when being mainly used in boom-type roadheader work and tail.
The present invention adopts following technical scheme to realize:
The stable mechanism of wagging the tail behind the development machine, support cylinder after comprising two that are connected with development machine body afterbody, the tailpiece of the piston rod of back support cylinder is articulated and connected with the back supporting leg, supporting leg is installed on respectively on left piston shoes and the right piston shoes after it is characterized in that two, left and right piston shoes are supported in to support on the base plate and also can move relative to supporting base plate, support base plate and be provided with supporting seat, the tailpiece of the piston rod of supporting seat and oscillating oil cylinder is hinged, and the cylinder barrel of oscillating oil cylinder and development machine body afterbody are hinged.
The position of corresponding left and right piston shoes is respectively arranged with the twice pressing plate on the described support base plate, and pressing plate is connected by bolt with the support base plate, and forming between pressing plate and the support base plate can be for the slideway of piston shoes slip, and piston shoes are arranged within the slideway.
During work, the piston rod of back support cylinder stretches out, back supporting leg falls and drives the support base plate by piston shoes and moves downward, after supporting base plate and ground contact, thrust by the back support cylinder supports the development machine body, when needs swing development machine tail, the operation oscillating oil cylinder can be realized development machine afterbody short distance swing.Employing has stabilising arrangement behind the development machine of the mechanism of wagging the tail, solved down-hole development machine tail swing difficulty, a difficult problem is frequently transferred in walking during turning, and stabilising arrangement and contact area of ground are big behind the development machine, has improved the stability when development machine is worked greatly.
The relative prior art of the present invention has following beneficial effect: the advantage of flexible movements, good stability, solved the problem that stabilising arrangement can not be swung behind the former development machine, and improved development machine tail swing, particularly the speed of Zhuan Waning is selected.Along with the increase of coal mining enterprise's fully-mechanized mining working, can strengthen day by day the demand of development machine, the application that has stabilising arrangement behind the development machine of the mechanism of wagging the tail also can be more and more wider, and the present invention has bigger market prospects.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present invention,
Fig. 2 is the lateral view of Fig. 1,
Fig. 3 is the vertical view of Fig. 1,
Among the figure: support cylinder behind the 1-, supporting leg behind the 2-, 3-supports base plate, 4-oscillating oil cylinder, the right piston shoes of 5-, 6-bolt, 7-nut, 8-pressing plate, 9-left side piston shoes, 10-supporting seat, 11-development machine body.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
The stable mechanism of wagging the tail behind the development machine, support cylinder 1 after comprising two that are connected with development machine body 11 afterbodys, the tailpiece of the piston rod of back support cylinder 1 is articulated and connected with back supporting leg 2, supporting leg 2 is installed on respectively on left piston shoes 9 and the right piston shoes 5 after it is characterized in that two, left and right piston shoes are supported in to support on the base plate 3 and also can move relative to supporting base plate 3, support base plate 3 and be provided with supporting seat 10, supporting seat 10 is hinged with the tailpiece of the piston rod of oscillating oil cylinder 4, and the cylinder barrel of oscillating oil cylinder 4 and development machine body 11 afterbodys are hinged.The position of supporting corresponding left and right piston shoes on the base plate 3 is respectively arranged with twice pressing plate 8, and pressing plate 8 is connected by bolt 6 with support base plate 3, forms the slideway that can supply piston shoes to slide between pressing plate 8 and the support base plate 3, and piston shoes are arranged within the slideway.There is hydraulically balanced valve to realize lock function on back support cylinder 1 and the oscillating oil cylinder 4.
During work, the piston rod of back support cylinder stretches out, back supporting leg falls and drives the support base plate by piston shoes and moves downward, after supporting base plate and ground contact, thrust by the back support cylinder supports the development machine body, when needs swing development machine tail, the operation oscillating oil cylinder can be realized development machine afterbody short distance swing.
