Abstract
A hydraulic gear rotating device relates to a rotating device enabling racks to drive a gear, can replace a motor and is good in safety. The technical scheme includes that the racks are fixed on two parallelly-arranged hydraulic cylinders, the gear is located between the two racks and meshed with the two racks simultaneously, and piston rods of two hydraulic cylinders are respectively fixedly hinged to a support. After oil openings of the hydraulic cylinders enter into pressure oil, cylinder bodies of the hydraulic cylinders move, the racks positioned on the cylinder bodies drive the gear meshed with the racks to rotate, the gear is further fixed on a rotating shaft, and rotation of the rotating shaft drives rotating components to rotate. The hydraulic gear rotating device is used for driving the rotating components in a coal-mine pit.
Description
Technical field
Hydraulic type gear whirligig of the present invention relates to a kind of whirligig of rack drives gear.
Background technique
Coal is a kind of non-renewable energy resources, also is the valuable source that guarantees national economic development, and in following considerable time, coal will account for the principal status of public economy in China's Energy Mix.
Along with the raising of colliery underground mining difficulty, mine disaster takes place frequently, and has been the incontrovertible fact.Gas explosion accident proportion in coal mining accident is higher; Gas explosion can produce huge impact ripple and hot flame, cause the dead crowd of crowd to hinder easily, and the coal dust of kicking up can participate in blast again, destroy tunnel, breaking-up equipment; Even the destruction whole mine, cause serious consequence.
The flach point of gas, the minimum temperature of promptly lighting gas.It is generally acknowledged that the flach point of gas is 650 ℃～750 ℃.But because of the concentration that receives gas, the character of burning things which may cause a fire disaster and the factor affecting such as pressure of mixed gas change.When content of gas 7% one 8% the time, the easiest igniting.The existence of high temperature burning things which may cause a fire disaster is one of necessary condition that causes gas explosion.The driving force of down-hole solid of rotation is mainly from motor, yet the electric spark that motor produces is a factor that causes gas explosion.
Summary of the invention
The present invention overcomes the deficiency of existing technology, and technical problem to be solved provides and a kind ofly can substitute motor, hydraulic type gear whirligig that Security is good.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: hydraulic type gear whirligig; Comprise first oil hydraulic cylinder, second oil hydraulic cylinder and gear, first oil hydraulic cylinder and second oil hydraulic cylinder laterally arrange, and the piston rod of first oil hydraulic cylinder is hinged on first bearing; Be fixed with guide pad on the cylinder body of said first oil hydraulic cylinder, said guide pad is positioned at guide rail; Also be fixed with first tooth bar on the cylinder body of said first oil hydraulic cylinder.
The piston rod of second oil hydraulic cylinder is hinged on second bearing, is fixed with guide pad on the cylinder body of said second oil hydraulic cylinder, and said guide pad is positioned at guide rail; Also be fixed with second tooth bar on the cylinder body of said second oil hydraulic cylinder.
Gear is fixed on the turning axle, and said gear meshes with first tooth bar and second tooth bar between first tooth bar and second tooth bar and simultaneously.
Said guide pad is a T shape piece, and said guide rail is provided with T-slot, and guide pad is positioned at T-slot.
The beneficial effect that the present invention compared with prior art has is: all be fixed with tooth bar on two oil hydraulic cylinders that laterally arrange, gear meshes with two tooth bars between two tooth bars and simultaneously, and the piston rod of two oil hydraulic cylinders is hingedly fixed on the bearing respectively; After the hydraulic fluid port of oil hydraulic cylinder gets into pressure oil; The cylinder body of oil hydraulic cylinder moves, rack drives on the cylinder body and the rotation of its meshed gears, and gear is fixed on the turning axle again; The rotation of turning axle drives the revolution part rotation; Realized the driving of revolution part having substituted the use of motor with the form of hydraulic pressure, so just reduced the potential safety hazard that the electric spark that produces because of motor causes gas explosion; And simple in structure, be easy to realize.

Embodiment
Embodiment 1
Like Fig. 1---Fig. 3; Hydraulic type gear whirligig of the present invention; Comprise that first oil hydraulic cylinder 3, second oil hydraulic cylinder 9 and gear 7, the first oil hydraulic cylinders 3 and second oil hydraulic cylinder 9 laterally arrange, the piston rod of first oil hydraulic cylinder 3 is hinged on first bearing 1; Be fixed with guide pad 2 on the cylinder body of said first oil hydraulic cylinder 3, said guide pad 2 is positioned at guide rail 4; Also be fixed with first tooth bar 5 on the cylinder body of said first oil hydraulic cylinder 3.
The piston rod of second oil hydraulic cylinder 9 is hinged on second bearing 11, is fixed with guide pad 2 on the cylinder body of said second oil hydraulic cylinder 9, and said guide pad 2 is positioned at guide rail 4; Also be fixed with second tooth bar 10 on the cylinder body of said second oil hydraulic cylinder 9.
Gear 7 is fixed on the turning axle 8, and said gear 7 meshes with first tooth bar 5 and second tooth bar 10 between first tooth bar 5 and second tooth bar 10 and simultaneously.
Said guide pad 2 is a T shape piece, and said guide rail 4 is provided with T-slot 6, and guide pad 2 is positioned at T-slot 6, the guiding when being used for movement of cylinder block.
When hydraulic type gear whirligig of the present invention is installed; First bearing 1 and second bearing 11 are positioned at the same side; The piston rod of the piston rod of first oil hydraulic cylinder 3 and second oil hydraulic cylinder 9 is in opposite state, and when promptly the piston rod of first oil hydraulic cylinder 3 was in contraction state, the piston rod of second oil hydraulic cylinder 9 was in the state of stretching out; Perhaps the piston rod of first oil hydraulic cylinder 3 is in when stretching out state, and the piston rod of second oil hydraulic cylinder 9 is in contraction state.
