Technical Field

The invention relates to a rescue tool, in particular to a portable valve switch special for rescue.

Background

The valve of the energy transmission pipeline generally has the functions of remote automatic control and manual field control. If a fire breaks out in the pipeline, the fire easily cuts off the automatically controlled power supply, so that the valve cannot be closed remotely. This requires the fire fighter to manually rotate the manual handle of the valve to close it on site. For large-scale pipeline valves, because of the large diameter, the manual handle needs to be rotated for thousands of turns to be completely closed. This requires a fire fighter in the fire scene to spend a lot of time and physical effort, which not only threatens the life safety of the fire fighter, but also delays the time for putting out a fire.

As an improvement of the scheme, the top of the switch body is provided with an end cover, and the bottom of the end cover is provided with a bearing seat; a first bearing is arranged in the bearing seat; the rotating disc is provided with a central rotating shaft, and the central rotating shaft is sleeved in the first bearing.

As the improvement of above-mentioned scheme, switch body both sides are equipped with the adapter mount pad, the adapter pass through the second bearing install in the adapter mount pad.

As an improvement of the above scheme, the clamping jaws at least comprise two straight rods which are arranged to deviate from the rotating axis of the rotating disc.

As an improvement of the scheme, the clamping claws are uniformly distributed on the circumferences which are at different distances from the rotating shaft center of the rotating disc.

As an improvement of the scheme, the handle is a straight rod extending out of the side face of the switch body in parallel.

As an improvement of the scheme, the adapter is connected with a pneumatic motor.

As the improvement of the above scheme, the adapter on one side of the switch body is provided with an inner four-corner connecting part, and the adapter on the other side is provided with a connecting rod.

The implementation of the invention has the following beneficial effects:

this scheme of adoption, the first-aid staff can be with the jack catch card of this device on the manual handle of valve, then utilize the broken instrument of tearing open of hand-carrying, like the most common pneumatic or electric spanner, stretch into the adapter with its output shaft, start pneumatic or electric spanner, make its output shaft drive the adapter rotatory, the rotary disk can drive the manual handle rotation of valve, closes the valve fast. The electric wrench for rescue is provided with a battery, the pneumatic wrench can use a high-pressure gas tank of a fireman as a gas source, the pneumatic wrench is not limited by a field power supply and a gas source, the structure is compact, the pneumatic wrench is convenient to carry, and the harsh use requirement of a rescue field can be met.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. It is only noted that the invention is intended to be limited to the specific forms set forth herein, including any reference to the drawings, as well as any other specific forms of embodiments of the invention.

As shown in fig. 1 to 4, a first embodiment of the present invention provides a rescue-dedicated portable valve switch, which includes a switch body 1, an adapter 2, a rotating disk 3 and a claw 4; the switch body 1 is provided with a handle 5; one end of the adapter 2 is connected with a rotating structure of a rescue common tool, and the other end of the adapter is provided with a driving gear 21; the top surface of the rotating disc 3 is provided with an end face fluted disc 31, and the driving gear 21 is meshed with the end face fluted disc 31 and can drive the end face rotating disc 3 to rotate relative to the switch body 1; the clamping jaws 4 are arranged at the bottom of the rotating disc 3 and extend outwards, so that a manual rotating disc of the valve can be fixedly connected. The top of the switch body 1 is provided with an end cover 6, and the bottom of the end cover 6 is provided with a bearing seat 61; a first bearing 7 is arranged in the bearing seat 61; the rotating disc 3 is provided with a central rotating shaft 32, and the central rotating shaft 32 is sleeved in the first bearing 7.

This scheme of adoption, the rescuer can be with 4 cards of jack catch of this device on valve hand handle 5, then the broken instrument of tearing open that the utilization was hand-carried, like most common pneumatic or electric spanner, stretch into adapter 2 with its output shaft, start pneumatic or electric spanner, make its output shaft drive adapter 2 rotatory, rotary disk 3 can drive valve hand handle 5 rotatory, closes the valve fast. The electric wrench for rescue is provided with a battery, the pneumatic wrench can use a high-pressure gas tank of a fireman as a gas source, the pneumatic wrench is not limited by a field power supply and a gas source, the structure is compact, the pneumatic wrench is convenient to carry, and the harsh use requirement of a rescue field can be met.

Preferably, 1 both sides of switch body are equipped with adapter mount pad 11, adapter 2 pass through second bearing 8 install in the adapter mount pad 11. The clamping jaws 4 at least comprise two straight rods which are arranged to deviate from the rotating axis of the rotating disc 3. Through two the straight-bar blocks manual handle 5 of valve, can adapt to not equidimension manual handle 5, and the commonality is strong.

More preferably, with reference to fig. 5, the claws 4 are evenly distributed on the circumference at different distances from the rotation axis of the rotating disc 3. Through setting up the distance the jack catch 4 of the different distances in the rotatory axle center of rotary disk 3, less manual handle 5 uses and fixes from the jack catch 4 that the rotatory axle center is nearer, and great manual handle 5 uses and fixes from the jack catch 4 that the rotatory axle center is far away, has further expanded the application scope of this device.
