Description

Technical Field

[0001] The utility model relates to the technical field of operating tools, in particular to a manual opening and closing tool for high-place valves. Background Art

[0002] At present, in order to better develop and rationally utilize land resources, most of the subway depots under construction in my country are under-cover depots, and most of them are commercial or residential. In the under-cover depot, the valves of fire-fighting, water supply and other pipelines are mostly installed on the ceiling using comprehensive supports and hangers due to objective factors such as construction conditions and convenience for maintenance. This design is conducive to the spatial optimization of pipelines and rapid leak detection, but if the valves of fire-fighting and water supply pipelines are in areas where it is inconvenient for climbing vehicles or personnel to enter, such as rail areas and above medium and high platforms, scaffolding needs to be set up or a 5-meter ladder is used to open or close these valves, which increases construction costs and time. At the same time, when the valves of fire-fighting, water supply and other pipelines are electric butterfly valves, if the electric butterfly valves are stuck or other faults occur, they need to be turned manually.

[0003] When the valves of water supply, fire protection and other pipelines are installed on the ceiling in the depot area under the cover, they are generally above the track contact network. If there is an emergency such as water leakage or burst in the pipeline, the whole site needs to be shut down before the aerial platform vehicle can enter the site to close the valve for emergency repair. The impact range is large and it takes a long time, which seriously affects the train operation. In the daily maintenance of the valve, it is necessary to ensure that the pipeline valve is not stuck and the switch is normal. Therefore, the valve needs to be turned according to the operating standards. When using the aerial platform vehicle for operation, the whole site needs to be shut down, the operation time is limited, and the maintenance cycle is long.

[0004] According to market research, the finished tools currently on the market cannot meet the actual use needs. Therefore, in the lower cover vehicle depot, special mechanical transmission tools with strong insulation, easy maintenance, diverse functions, and detachable assembly are needed to open and close the high-altitude valves without the need for high-altitude operations.

[0005] Therefore, it is necessary to provide a new manual opening and closing tool for high-altitude valves to solve the above-mentioned technical problems. Utility Model Content

[0029] It should be noted that: when in use, the staff can lift the device to insert the protruding rod 21 at the bottom of the worm gear 2 into the valve turntable to be opened or closed, and then control the joystick 4 to move up and down reciprocatingly. During this process, the joystick 4 can smoothly drive the corresponding second rotating rod 14 to rotate through the connecting block 62, the shaft rod 61 and the connecting piece 6;

[0030] At this time, the second rotating rod 14 will smoothly drive the worm 3 at the end to rotate, so that the gripping rod can smoothly mesh with the worm wheel 2 to rotate, so that it can smoothly drive the convex rod 21 on the outer wall to rotate, so that the outer wall of the convex rod 21 can smoothly abut against the inner wall of the rotary disk in the valve to be opened or closed, and then can smoothly drive the rotary disk in the corresponding valve to rotate, so as to realize the opening or closing operation of the valve, and the whole operation process is more convenient and quick;

[0031] The tool can open and close valves in complex areas that are inaccessible to climbing equipment or personnel, such as valves above pipelines on medium and high platforms, valves high up in track areas, etc. It does not require scaffolding or other climbing operations, has a high safety factor, and can effectively reduce the occurrence of safety accidents.

[0032] It should also be noted that: there are multiple operating rods 4 and fixed rods 5, and the corresponding operating rods 4 and fixed rods 5 are spliced ​​by screwing together, so that the length can be flexibly adjusted according to the usage conditions in the later use, which can meet the use of valves of different heights.

[0033] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 A plurality of evenly distributed mounting holes 23 are formed at the bottom of the worm wheel 2 , and the interior of the mounting holes 23 is threadedly connected to the top end of the protruding rod 21 .

[0034] It should be noted that: by setting a number of evenly distributed mounting holes 23, during later use, the positions of the several protruding rods 21 can be adjusted according to the size of the turntable or handle in the valve of different models and specifications, so that the protruding rods 21 can be smoothly abutted against the outer wall of the turntable or handle in the valve at a later time, and can subsequently smoothly drive the corresponding turntable or handle to rotate.

[0035] In the embodiments of the present invention, please refer to Figure 1 and Figure 3 A through hole 22 is opened at the center of the worm wheel 2, and the inside of the through hole 22 is abutted against and rotatably connected to the outer wall of the insertion rod 11. A limiting sleeve 12 is sleeved below the outside of the insertion rod 11, and the top of the limiting sleeve 12 is abutted against and rotatably connected to the bottom of the worm wheel 2.

[0036] It should be noted that: by sleeved the limiting sleeve 12 on the outer wall of the insertion rod 11, after the worm wheel 2 is sleeved on the outer wall of the insertion rod 11 later, the limiting sleeve 12 can smoothly limit the worm wheel 2, so that the worm wheel 2 can stably rotate on the outer wall of the insertion rod 11 later.

[0037] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 Two staggered first connecting holes 15 and second connecting holes 16 are provided on one side of the outer wall of the support frame 1 close to the first rotating rod 13 , and the first connecting holes 15 and the second connecting holes 16 are both threadedly connected to the end of the fixing rod 5 .

The overall layout is shown in the attached Figure 1 "Vertical Valve Working Mode", Annex Figure 2 "Flush valve working mode".

[0039] The working principle of the manual opening and closing tool for high-altitude valves provided by the utility model is as follows:

[0040] When using the tool later, the staff can first assemble and splice the operating rod 4 and the fixing rod 5 according to the needs until they reach the required length, and then screw them into the connecting block 62 and the corresponding first connecting hole 15 or second connecting hole 16 respectively, and the assembly of the device can be completed;

[0041] At this time, the staff can lift the device so that the protruding rod 21 at the bottom of the worm gear 2 can be smoothly inserted into the valve turntable to be opened or closed, and then the joystick 4 can be controlled to move up and down reciprocatingly. In this process, the joystick 4 can smoothly drive the corresponding second rotating rod 14 to rotate through the connecting block 62, the shaft rod 61 and the connecting piece 6;

[0042] At this time, the second rotating rod 14 will smoothly drive the worm 3 at the end to rotate, so that the gripping rod can smoothly engage and rotate with the worm wheel 2, thereby smoothly driving the convex rod 21 on the outer wall to rotate, so that the outer wall of the convex rod 21 can smoothly abut against the inner wall of the turntable in the valve to be opened or closed, and then smoothly drive the turntable in the corresponding valve to rotate, thereby realizing the opening or closing operation of the valve, and the whole operation process is more convenient and quick.
