Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

As shown in fig. 1-2, the present utility model provides a butterfly valve operating tool 9100, which includes a fixed base plate 9110, a fixed arm 9120 and a movable arm 9130, wherein the fixed arm 9120 is fixedly connected to the fixed base plate 9110, and when in use, the fixed base plate 9110 is fixedly connected to a tool end of a mechanical arm; the moving arm 9130 is movably connected to the fixed base plate 9110 and can move relatively to the fixed arm 9120; wherein the fixing arm 9120 extends obliquely downward from the fixing base plate 9110, a hook return structure 9121 is disposed at the end of the fixing arm 9120, a vertical abutment portion 9122 is disposed on the fixing arm 9120 inside the hook return structure 9121, and the top of the hook return structure 9121 is lower than the top of the abutment portion 9122; the moving arm 9130 is located at a side of the fixed arm 9120, and extends obliquely downward together with the fixed arm 9120, and a vertical downward clamping portion 9131 is provided at a distal end, a lower end of the clamping portion 9131 is lower than a top of the hook return structure 9121 but not lower than a bottom of the hook return structure 9121, and an upper end of the clamping portion 9131 is level with a height of the abutting portion 9122, so that a distance between the clamping portion 9131 and the abutting portion 9122 becomes small after retraction, and thus a valve rod can be clamped and unlocked, so that the valve rod can be lifted further to open.

The fixed arm 9120 and the movable arm 9130 both adopt a mode of extending obliquely downwards, so that the purpose is to avoid a tool with a tool end of the mechanical arm directly connected, and the valve rod of the butterfly valve can be conveniently operated by adopting an oblique downward detection mode, so that a gap between the valve rod of the butterfly valve and the upper surface of the tank can be conveniently cut into by adopting an oblique mode.

The abutment portion 9122 is formed by an abutment block connected to the fixing arm 9120, and the abutment portion is a separate structural component independent of the fixing arm 9120 and is fixed to the fixing arm by means of screw connection, so that the abutment portion can be individually designed and replaced to adapt to different working situations.

The abutting portion 9122 is integrally formed on the fixing arm 9120, and the structural size of the fixing arm can be reduced by adopting the integrally formed abutting portion, so that the operation is more convenient.

The abutment 9122 includes a rubber surface to ensure that the clamped valve stem does not easily rotate, unhook, etc.

The downward inclination of the movable arm 9130 is less than the downward inclination of the stationary arm 9120, thereby forming a pointed structure between the movable arm and the stationary arm, and the distance between the movable arm and the end of the stationary arm is maximized, thereby avoiding upward play of the held valve stem along the gap between the stationary arm and the movable arm.

The length of the return hook 9121 in the vertical direction is no more than half of the abutment 9122, thereby making the return hook 9121 easier to cut from between the valve stem and the upper surface of the canister.

The fixed and movable arms 9120, 9130 are inclined at an angle of between 30 and 60 degrees, and in extreme cases, between 15 and 75 degrees.

The fixed base plate 9110 is provided with a linear guide rail 9111 and a slider 9112 that extend horizontally, and the slider is connected to the moving arm 9130 and is driven by a telescopic driving device 9113 on the fixed base plate 9110 to move.

The telescopic driving device is a telescopic cylinder.

The device further comprises a frame structure 9114, wherein the frame structure 9114 is sleeved outside the fixed substrate 9110, and the moving arm 9130 and the sliding block are respectively and fixedly connected with the frame structure; the telescopic driving device is connected to the lower portion of the fixed base plate 9110 to drive the frame structure, so that the sliding block is driven to move by the frame structure. The design of the frame structure 9114 can make the driving position of the telescopic driving device different from the connecting position of the sliding block, so that the structural layout of the whole butterfly valve operating tool is more reasonable, and the occupation of space is reduced.

The frame structure 9114 is a square structure formed by splicing and connecting four flat plates.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
