Description
Technical field
The utility model relates to oil field beam pumping unit technical field, particularly a kind of safty device that are used for the brake of pumping unit secondary.
Background technique:
It is beam pumping unit that the oil field is recovered the oil widely used.In shutdown of pumping machine, maintaining process, if fail in time to lock arming pin, when brake has fault, serious security incident takes place very easily, the lighter causes the damage of equipment, and weight person can cause casualties.
On the structural design of beam pumping unit, the general brake secondary safty device that adopt, the brake secondary safty device arming pin device that is referred to as to brake.Some types have special brake arming pin design, but the brake arming pin is deviate from from draw-in groove easily when clockwise rotating, and loses the secondary safety effect.There are some pumping unit types not have special brake arming pin design.The pumping unit of a kind of model of producing as certain machinery plant, thus it is to reach the purpose of brake insurance by tightening brake block pull bar screw locking brake hub, fails will to realize according to braking in the relevant pumping unit operation to force the regulation of fixing.Therefore the safety coefficient of this pumping unit is not high.Be necessary pumping unit brake safety installations is improved, prevent that the insurance of pumping unit brake secondary from causing the generation of mechanical failure and personal injury accident after malfunctioning.
The model utility content
The purpose of this utility model is: a kind of pumping unit spring brake arming pin is provided, can realizes the insurance of pumping unit brake secondary effectively.Solve and deviate to cause the accident hidden danger when pumping unit brake arming pin clockwise rotates bayonet lock easily,, stopped because brake failure causes the generation of mechanical failure and personal injury accident for the operative employee provides safer, reliable working environment.
The technical solution adopted in the utility model is: pumping unit spring brake arming pin mainly is made up of sphere handle, housing, spring, night bolt, plug and limit stoper.Shell construction is cylindric, and housing one end has the end, and center, the end is porose.The housing the other end has screw thread.Night bolt is arranged in the housing, and night bolt is that a cylindric end has screw thread.There is spring planet at the middle part of night bolt.The night bolt threaded end passes the center hole of housing bottom.Be fixed with spherical handle on the night bolt end thread.Between housing bottom and spring planet, spring is arranged.On the screw thread of the housing the other end, be fixed with plug.Plug has center hole, and the other end of night bolt passes the plug center hole.When the spherical handle of pulling drove night bolt, the night bolt end can be flat with the plug exterior edge face.Between sphere handle and housing bottom, there is limit stoper that night bolt is fixed.When removing limit stoper, night bolt resets under the effect of spring, and the other end of night bolt stretches out outside the plug center hole.
Described limit stoper can be the U-shaped clamp.The U-shaped clamp can directly insert between spherical handle and the housing bottom, prevents that night bolt from resetting.
Described limit stoper can be: jack is arranged on night bolt, insert an inserted link in jack, can play the effect that prevents that night bolt from resetting equally.
Described spring is a pressure spring.
The external cylindrical surface of described plug is stepped, and stepped external cylindrical surface has outside thread.An outside thread can be fixed on the screw thread of the housing the other end, and an outside thread can make the utility model pumping unit spring brake arming pin be fixed on the pumping unit brake block.
The working principle of pumping unit spring brake arming pin:
Pumping unit spring brake arming pin is fixed on the pumping unit brake block, and evenly distributing on the corresponding former pumping unit brake hub is drilled with a jack, in order to insert night bolt.
When needs carry out shutdown of pumping machine, maintaining, at first braking device is stopped tight after, the sphere handle of pull-up spring brake arming pin takes off spring clamp, at this moment night bolt inserts jack, realizes locking between pumping unit brake block and the brake hub.After the something unexpected happened brake failure, brake hub begins to rotate, when brake hub turns to jack and night bolt position consistency, night bolt inserts the brake hub jack automatically under the effect of spring, thereby stop brake hub to be rotated further, enter lock state, reach the purpose of secondary brake after the brake failure, and realized the fixing by force of brake.
After shutdown of pumping machine, maintaining process operation finish, pull up spherical handle, insert spring clamp, at this moment the brake hub jack is withdrawed from the night bolt top, unlocks between pumping unit brake block and the brake hub, and brake hub is got back to free state again.
The beneficial effects of the utility model: the utility model pumping unit spring brake arming pin, can realize the insurance of pumping unit brake secondary.Eliminated and deviate to cause the accident hidden danger when pumping unit brake arming pin clockwise rotates bayonet lock easily.For the operative employee provides safer, reliable working environment, stopped because brake failure causes the generation of mechanical failure and personal injury accident.
Once certain pumping unit had been installed additional pumping unit spring brake arming pin,, fundamentally solved the existing problem of brake arming pin of present use, and also can solve the problem that the part type does not have special brake arming pin design from the situation of The field.The secondary vi have high safety of pumping unit spring brake arming pin, easy to operate, processing is simple, and is easy for installation.
