Description
Technical field
The utility model is related to a kind of switch module of oil-well drilling equipment, more particularly to a kind of liquid gas tong hydraulic control valve
Safety switch assembly.
Background technology
Liquid gas tong is the indispensable equipment of oil drilling round trip, and the hydraulic control valve of liquid gas tong is control
One of important Hydraulic Elements of hydraulic tongs positive and negative rotation are realized by the control hydraulic tongs positive and negative rotation of liquid gas tong hydraulic control valve and are bored
The upper shackle of tool, the use of liquid gas tong alleviate labor intensity to operator, improve the working efficiency of round trip, but
It is, since the operation handle on the hydraulic control valve of existing liquid gas tong lacks limiting locking device, the hydraulic pressure control in operation
Threshold switch handle processed often makes liquid gas tong rotate because touching or maloperation etc. are unexpected.Security risk is brought to operator,
Petroleum industry because touching or maloperation hydraulicdirectional control valve to operator caused by personal injury accident it is not within minority, therefore, it is necessary to
A kind of safety switch assembly of liquid gas tong hydraulic control valve is developed, realizes that the handle of hydraulic control valve limits by component, lock
Determine operation handle and realizes safety work.
Invention content
The technical problem to be solved by the present invention is to provide a kind of liquid gas tong hydraulic control valves during use
Switch knob automatic spacing locks, will not be because of the unexpected hydraulic control valve safety open for making liquid gas tong rotate such as touching or maloperation
Close component.
In order to solve the above technical problems, the technical solution of the utility model is：One kind being used for liquid gas tong hydraulic control valve
Safety switch assembly, including it is outdoor handle, inner handle, handle set, L-type limit base, handle pivot pin, supporting rod, limiting slot, O-shaped
Spacing collar, compressed spring, L-type limit base state are scheduled among hydraulic control valve and handle set, are arranged on L-type limit base limited
Position slot is provided with O-shaped spacing collar among limiting slot, and one section of the outdoor handle is provided with cavity, and cavity front end is equipped with baffle ring, interior hand
Handle rear end is in convex, and in outdoor handle cavity, the inner handle wraps up compressed spring, compression with outdoor handle inner cavity inserted terminal for grafting
Spring realizes that outdoor handle and inner handle are flexible, and the inner handle other end is connected on hydraulic control valve, and inner handle is a little and supporting rod
Connection.
Further, a kind of safety switch assembly for liquid gas tong hydraulic control valve, the front of outdoor handle
Interior diameter is more than the diameter of inner handle, and the length of outdoor handle front cavity is equal to the length of compressed spring.
Further, a kind of safety switch assembly for liquid gas tong hydraulic control valve, O-shaped spacing collar
Diameter is equal to the diameter of outdoor handle.
Further, a kind of safety switch assembly for liquid gas tong hydraulic control valve, the width of limiting slot
Equal to the diameter of inner handle.
The utility model has the advantage of：Outdoor handle is realized by compressed spring and inner handle to be stretched, when outdoor handle is extracted out
When compressed spring compressed, outdoor handle is detached from the O-shaped spacing collar on L-type limit base, and inner handle moves up and down along limiting slot, leads to
It crosses hydraulic control valve and realizes liquid gas tong positive and negative rotation, carry out shackle operation；When operation is completed to unclamp outdoor handle, pass through the right-hand side
Compressed spring elasticity in handle cavity makes to retract outside outdoor handle, and outdoor handle is locked on the O-shaped spacing collar on L-type limit base, real
The switch knob locking of existing hydraulic control valve；The utility model is simple in structure, easy to manufacture.
