Description
Technical field
A kind of hydraulic type wire rope of the utility model whirligig relates to the whirligig that a kind of wire rope drives wire rope pulley.
Background technique
China is a big coal country, is a serious country that relies on the coal energy, also is mine disaster big country simultaneously.Illegal mining colliery, production are slipped up, apparatus wears out, and artificial origins such as reaching fault is the main cause of mine disaster.
Gas and air mixing, the phenomenon of abrupt oxidization at high temperature, and generation shock wave is the major disaster in the Coal Production.Extensive gas explosion took place in Britain Mo Siting (Mostyn) ore deposit in 1675, and great gas or gas and dust explosion accident all once repeatedly took place in each country of mainly mining thereafter.On April 26 nineteen forty-two, gas and coal-dust explosibility take place in the colliery, Chinese Benxi under Japan occupies, and 1528 people that die instantly hinder 268 people, are maximum in the world explosion of coal mine accident.With the development of Coal Production technology and the improvement of control gas measure, this type accident reduces gradually.
The burning things which may cause a fire disaster of China's coal mines gas explosion mainly is electrical spark and explosion, and main scene is a getting working face.The instantaneous temperature that coal mine gas from explosion produces can reach 1850～2650 ℃, and pressure can reach nine times of first pressing, and gas outwards impacts with the speed more than the per second hundreds of rice near the explosive source, makes casualties, and tunnel and equipment facility damage.Blast back concentration of oxygen reduces, and generates great amount of carbon dioxide and carbon monoxide, and the danger that suffocates and poison is arranged.
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.
The model utility content
The utility model overcomes the deficiency of existing technology, and technical problem to be solved provides and a kind ofly can substitute motor, a kind of hydraulic type wire rope whirligig that Security is good.
For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: a kind of hydraulic type wire rope whirligig; Comprise first oil hydraulic cylinder, second oil hydraulic cylinder and wire rope; First oil hydraulic cylinder and second oil hydraulic cylinder laterally arrange, and the middle part of first hydraulic cylinder body is provided with first bearing, and first wire rope pulley is installed on the piston rod of said first oil hydraulic cylinder.
The middle part of second hydraulic cylinder body is provided with second bearing, and the 3rd wire rope pulley is installed on the piston rod of second oil hydraulic cylinder.
Second wire rope pulley is fixed on the turning axle; Said second wire rope pulley is between first oil hydraulic cylinder and second oil hydraulic cylinder and through simultaneously wire rope and first wire rope pulley and the 3rd wire rope pulley transmission, and the two ends of wire rope are separately fixed on the cylinder body of first oil hydraulic cylinder and on the cylinder body of second oil hydraulic cylinder.
The beneficial effect that the utility model compared with prior art has is: on the piston rod of two oil hydraulic cylinders that laterally arrange wire rope pulley is installed all, the wire rope pulley that is used for transmission is between two oil hydraulic cylinders, and two oil hydraulic cylinders are fixed through the bearing that is arranged on the cylinder body middle part; During the piston rod movement of one of them oil hydraulic cylinder; Wire rope pulley rotation mounted thereto, the piston rod reversing motion of another oil hydraulic cylinder is in the process of wire rope pulley rotation; Employ wire rope pulley rotation through rope belt in transmission; The wire rope pulley that is used for transmission is fixed on turning axle again, and the rotation of turning axle drives the revolution part rotation, has realized the driving of revolution part with the form of hydraulic pressure; Substituted the use of motor; Just reduced the potential safety hazard that the electric spark that produces because of motor causes gas explosion, and simple in structure like this, be easy to realize.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of a kind of hydraulic type wire rope of the utility model whirligig.
Among the figure: 1 is that first oil hydraulic cylinder, 2 is that first bearing, 3 is that wire rope, 4 is that first wire rope pulley, 5 is that turning axle, 6 is that second wire rope pulley, 7 is that the 3rd wire rope pulley, 8 is that second oil hydraulic cylinder, 9 is second bearing.
Embodiment
Like Fig. 1; A kind of hydraulic type wire rope of the utility model whirligig; Comprise first oil hydraulic cylinder 1, second oil hydraulic cylinder 8 and wire rope 3; First oil hydraulic cylinder 1 and second oil hydraulic cylinder 8 laterally arrange, and the middle part of first oil hydraulic cylinder, 1 cylinder body is provided with first bearing 2 and is used for supporting and first oil hydraulic cylinder 1 being installed, and first wire rope pulley 4 is installed on the piston rod of said first oil hydraulic cylinder 1.
The middle part of second oil hydraulic cylinder, 8 cylinder bodies is provided with second bearing 9 and is used for supporting and second oil hydraulic cylinder 8 being installed, and the 3rd wire rope pulley 7 is installed on the piston rod of said second oil hydraulic cylinder 8.
