Abstract

The invention discloses a multipurpose valve handle. A prism is arranged on the corresponding position where the center of the handle and the axis of a transmission rod are overlapped, the prism rotates and drives the transmission rod to rotate, and the transmission rod rotates to change the opening and closing states of a valve. The handle can be operated manually on normal situations, a robot provided with a sleeve and matched with the prism enters the site when emergency or danger occurs and it is dangerous for people to enter the site, the sleeve is arranged on the prism in a sleeved mode, the prism can be rotated by rotating the sleeve, and the prism drives the transmission rod to rotate, and accordingly the opening and closing states of the valve are changed and the aim of eliminating safety hidden hazards is achieved.

Description

Multi-purpose valve door handle

Technical field

The present invention relates to a kind of valve handle, specifically all exercisable valve handles of a kind of people and mechanism hand.

Background technique

Valve is as in a kind of equipment extensive use and production, living, valve comprises manually and multiple kinds such as electronic, hydraulic valve, pneumatic valve, and manually-operated gate still has considerable use, particularly under the state of emergency, when having a power failure, stopping the supple of gas or steam, manually-operated gate has been the last barrier of safety guarantee.The manually-operated gate that existing moment of torsion is larger, its handle is in the majority with disc format, and its design is exactly in order to facilitate the operation of staff.On the other hand, along with the progress of technology, Robotics is also in fast development, robot is except replacement or auxiliary people's processed product, an important application direction is to provide the rescue at nature or human-made disasters scene, as chemical plant, nuclear power station occurs after catastrophic failure, what first enter is artificially main with machine, discharge dangerous situation, close corresponding valve, but existing manually-operated gate handle design is with artificially main, people's hand is very flexible, the size of strength and the utilization of direction are also very accurate, so operating, the valve handle people of existing disc-like do not have any problem, if but operate by robot, more complicated, once strength size and Orientation on there is larger error, light cause the damage of valve handle, heavy make valve body occur destroy, thereby produce larger trouble.Though existing Disaster Relief Robot is few, but the construction of existing chemical plant, nuclear power station is also being carried out on a large scale, in the near future, in the time that Disaster Relief Robot is generally applied, a large amount of chemical plant and nuclear power station etc. have all built up, its valve is still and is suitable for that people operates, no matter be to change the equipment of Disaster Relief Robot or changing mounted valve handle is all a kind of huge waste at that time, so the valve handle that is suitable for human-machine dual-purpose is from now just having considered.

Summary of the invention

Technical problem to be solved by this invention is, for above-mentioned deficiency of the prior art, to provide a kind of multi-purpose valve door handle, can be when needed or when urgent, replaced people's operation by robot manipulation, and reduce the threat of hazardous location to people.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of multi-purpose valve door handle, is characterized in that: the corresponding position coinciding at the center of handle, with drive link axis is mounted with prism, and the rotation of this prism will drive the rotation of drive link, and the latter's rotation changes the open and-shut mode of valve.

The cross section of described prism is one of equilateral triangle, square, regular pentagon, regular hexagon, positive seven distortion and octagon.

Described prism tips has chamfering.So that the sleeve being installed in robot is easy to be set with work on it.

Described prism and drive link are one.

The present invention compared with prior art has the following advantages:

This handle under normal circumstances people's handling is still passable, but urgent or when dangerous when occurring, people enters in on-the-spot breakneck situation, dependence is mounted with the robot that sleeve and this sleeve mate with prism, just can reverse the drive link of respective valves, thereby with the switching of movable valve, get rid of potential safety hazard.

Below by drawings and Examples, technological scheme of the present invention is described in further detail.

Accompanying drawing explanation

Fig. 1 is the structural representation of the specific embodiment of the invention.

Fig. 2 is the structural representation of Fig. 1 lateral plan.

Description of reference numerals:

1-handle; 2-prism; 3-drive link.

Embodiment

A kind of multi-purpose valve door handle as shown in Figure 1, it is characterized in that: the corresponding position coinciding at the center of handle 1, with drive link 3 axis is mounted with prism 2, the rotation of this prism 2 will drive the rotation of drive link 3, and the latter's rotation changes the open and-shut mode of valve.This handle under normal circumstances people's handling is still passable, but urgent or when dangerous when occurring, people enters in on-the-spot breakneck situation, dependence is mounted with sleeve and this sleeve enters scene with the robot that prism 2 mates, and by sleeve set on prism 2, turnbarrel, just can reverse prism 2, the latter drives again drive link 3 to rotate, thereby the open and-shut mode of valve is changed, and reaches the object of getting rid of potential safety hazard.

Preferably, the cross section of described prism 2 is one of equilateral triangle, square, regular pentagon, regular hexagon, positive seven distortion and octagon.

Preferably, there is chamfering on described prism 2 tops.So that the sleeve being installed in robot is easy to be set with work on it.

Preferably, described prism 2 is one with drive link.Be to be processed by a root timber material, cost is low like this, and intensity is high.

The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification of above embodiment being done according to the technology of the present invention essence, change and equivalent structure change, and all still belong in the protection domain of technical solution of the present invention.

Claims

1. a multi-purpose valve door handle, it is characterized in that: the corresponding position coinciding at the center of handle (1), with drive link (3) axis is mounted with prism (2), the rotation of this prism (2) will drive the rotation of drive link (3), and the latter's rotation changes the open and-shut mode of valve.

2. a kind of multi-purpose valve door handle according to claim 1, is characterized in that: the cross section of described prism (2) is one of equilateral triangle, square, regular pentagon, regular hexagon, positive seven distortion and octagon.

3. a kind of multi-purpose valve door handle according to claim 1, is characterized in that: there is chamfering on described prism (2) top.
