EMBODIMENT
[0028] The technical scheme of the utility model will be described clearly and completely in combination with embodiments, and obviously, the described embodiments are a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0029] As Figures 1-4As shown, one embodiment of the utility model provides a valve screwing auxiliary device for installing on a valve handle, which comprises a handle piece 4 and first and second bending pieces and a connecting rod 1 connected in sequence.
[0030] The first and second bending pieces are adapted to the ring handle 5 of the valve handle, and the bending directions of the first and second bending pieces are opposite.
[0031] The handle piece 4 is fixed perpendicularly to the connecting rod 1 near one end of the second bending piece.
[0032] When the valve is rotated counterclockwise using the valve screwing auxiliary device, the valve screwing auxiliary device is installed on the valve handle as shown, for the convenience of description, the direction toward the inner side of the paper is named as the rear, the direction toward the outer side of the paper is named as the front, and one of the connecting columns 6 in the figure is named as the first connecting column 61. Figure 2 Figure 2 The first bending piece extends into the back of the ring handle 5 from the rear of the ring handle 5, is located at the left side of the first connecting column 61, and is in contact with the connecting part of the ring handle 5. The second bending piece is clamped on the front of the ring handle 5 from the front of the ring handle 5, and the side of the connecting rod 1 facing the side of the valve rod 7 is in contact with the side of the valve rod 7.
[0033] In this way, when the valve is rotated counterclockwise, the operator holds the handle piece 4 with one hand or both hands and rotates the handle piece 4 counterclockwise. Since the end of the first bending piece is located at the left side of the first connecting column 61, and the first bending piece is in contact with the contact part of the first connecting column 61 and the ring handle 5, and the side of the connecting rod 1 facing the side of the valve rod 7 is in contact with the side of the valve rod 7, the entire valve handle is driven to rotate counterclockwise with the first bending piece as the force point and the contact position of the connecting rod 1 and the valve rod 7 as the fulcrum. The basic principle of rotating the valve clockwise is the same as that of rotating the valve counterclockwise, and will not be described here.
[0034] Compared with the previous method of continuously crossing the valve handle with both hands, the first and second bending pieces are arranged, the handle piece 4 is arranged on the valve handle, and the worker no longer uses the method of holding the ring handle 5 with both hands and crossing to open or close the valve, so there is no technical problem of interference with both hands, and it is more labor-saving.
[0035] The operation time for opening or closing the valve is saved, and a certain safety time is reserved in case of emergency.
[0036] In addition, the time for high-altitude operation is reduced, and the labor burden of the operator is reduced.
[0037] As a preferred embodiment, the connecting rod 1 is a long strip plate, the first bending member is a first bending plate 2, and the second bending member is a second bending plate 3. From Figure 1 It can be seen that the first bending plate 2, the connecting rod 1 and the second bending plate 3 are connected in sequence, and the opening direction of the first bending plate 2 points to the upper side of the connecting rod 1, and the opening direction of the second bending plate 3 points to the lower side of the connecting rod 1. The handle member 4 is installed on the connecting rod 1 near the second bending plate 3 and is perpendicular to the connecting rod 1.
[0038] It should be noted that the first bending plate 2 and the second bending plate 3 in the embodiment are completely the same in structure and are matched with the ring handle 5. That is, the first bending plate 2 can hook the ring handle 5 from the back of the ring handle 5, and the second bending plate 3 can hook the ring handle 5 from the front of the ring handle 5.
[0039] When the valve is counterclockwise rotated using the valve screwing auxiliary device, the valve screwing auxiliary device is installed as shown in the state of Figure 2 , so that the first bending plate 2 extends from the back of the ring handle 5 and hooks the back of the ring handle 5, and the first bending plate 2 is located on the left side of the first connecting column 61 and abuts against the first connecting column 61. Meanwhile, the second bending plate 3 hooks the front of the ring handle 5, and the side of the connecting rod 1 facing the valve stem 7 contacts the side of the valve stem 7. In this way, when the valve is counterclockwise rotated, the operator holds the handle member 4 with one hand or two hands and rotates in the counterclockwise direction. The valve screwing auxiliary device takes the contact position of the connecting rod 1 and the valve stem 7 as the fulcrum and takes the first bending plate 2 as the force point to first act on the first connecting column 61, thereby driving the entire valve handle to rotate counterclockwise.
[0040] When the valve is clockwise rotated using the valve screwing auxiliary device, the valve screwing auxiliary device needs to be reinstalled, that is, the valve screwing auxiliary device is placed to the left side of the valve stem 7 in Figure 2 , so that the right side of the connecting rod 1 abuts against the side of the valve stem 7, the first bending plate 2 extends from the back of the ring handle 5 and hooks the back of the ring handle 5, the first bending plate 2 is located on the right side of the first connecting column 61 and abuts against the first connecting column 61, and the second bending plate 3 hooks the front of the ring handle 5.
[0041] It should be noted that the first connecting column 61 in the embodiment is not a specific connecting column 6 in the valve, but is named as the first connecting column 61 for the convenience of description. That is, the valve screwing auxiliary device can be matched with any one of the connecting columns 6 in the valve handle when in use.
[0042] In the embodiment, more specifically, the connecting rod 1 has first and second parallel faces (i.e. Figure 1The inner wall of the first bending piece, the first face of the connecting rod 1 and the outer wall of the second bending piece are sequentially connected, and the outer wall of the first bending piece, the second face of the connecting rod 1 and the inner wall of the second bending piece are sequentially connected.
[0043] Preferably, the first bending plate 2, the connecting rod 1 and the second bending plate 3 are integrally formed by a metal plate, and specifically, an alloy steel plate (for example, Q460 high-strength low-alloy steel) or a high-hardness wear-resistant steel plate can be used for the integral forming. The Q460 high-strength low-alloy steel will not be plastically deformed until the stress intensity reaches 460 MPa. The first bending plate 2 and the second bending plate 3 are bent and formed.
[0044] As an optional embodiment, the connecting rod 1 in the valve screwing auxiliary device is a round bar or a round pipe, and the first bending piece and the second bending piece are both bent bars or bent pipes.
[0045] In this embodiment, in order to improve the flexibility of the operator using the valve screwing auxiliary device, the body force can be better saved.
[0046] As shown in Figure 1 and Figure 3 , the handle piece 4 includes a wire 401, at least one first locking nut 402, at least one second locking nut 403, a plurality of bearings 404 and at least one third locking nut 405. The connecting rod 1 has a circular hole at one end near the second bending plate 3 for the wire 401 to pass through.
[0047] It should be noted that the wire 401 has a region without threads, and this region is used to install the bearings 404. In order to facilitate description, this region is named as a non-threaded region.
[0048] According to the direction shown in Figure 1 , when installing the handle piece 4, the wire 401 is passed through the circular hole on the right side of the connecting rod 1 from top to bottom, and then at least one first locking nut 402 is screwed on the bottom end of the wire 401 and tightened, followed by screwing at least one second locking nut 403 on the top end of the wire 401 and tightening, and the wire 401 is firmly fixed to the connecting rod 1 through the cooperation of the first locking nut 402 and the second locking nut 403. Then a plurality of bearings 404 are sequentially inserted from the top end of the wire 401, and the bearings 404 are fixed to the non-threaded region of the wire 401, at this time the lowermost bearing 404 falls on the uppermost second locking nut 403. Finally, the third locking nut 405 is screwed on the top end of the wire 401, so that the lower surface of the third locking nut 405 is in contact with the uppermost bearing 404.
[0049] It should be noted that in the handle 4, the main role of the first locking nut 402 and the second locking nut 403 is to install the wire 401. The second locking nut 403 and the third locking nut 405 cooperate to limit the movement range of the bearing 404.
[0050] When the valve handle is rotated using the valve rotation assisting device, the operator holds the bearing 404 of the handle 4. Since the inner ring of the bearing 404 is in interference fit with the non-threaded area of the wire 401, and the outer ring of the bearing 404 can rotate relative to the wire 401, the bearing 404 can adapt to the rotating action of the operator's hand, reducing the friction between the operator's hand and the handle 4, so that the valve handle can be rotated more smoothly and flexibly, and more labor-saving.
[0051] In addition, the handle 4 is set in the above-mentioned detachable form, so that the handle 4 can be reused, and the connecting rod 1 can be replaced subsequently.
[0052] In order to avoid the loosening problem of the first locking nut 402 and the second locking nut 403, as shown in Figure 1 and Figure 3 The first locking nut 402 is provided with two, and the second locking nut 403 is also provided with two. Of course, the third locking nut 405 can also be provided in multiple.
[0053] Optionally, in order to avoid the palm of the operator being rested on the second locking nut 403 and the third locking nut 405 when the operator holds the handle 4, a rubber sleeve can be provided outside the third locking nut 405 and the second locking nut 403.
[0054] Of course, in the present embodiment, in order to improve the adaptability of the valve rotation assisting device, so that the valve rotation assisting device can adapt to valve handles of different diameters, the connecting rod 1 can be provided in a telescopic manner, that is, the length of the connecting rod 1 can be adjusted.
[0055] Preferably, the connecting rod 1 comprises a first rod body and a second rod body, both of which are long strip plates, a plurality of mounting holes are uniformly provided on the first rod body and the second rod body along the respective length directions, and the first rod body and the second rod body are fixed by fixing bolts and fixing nuts. By changing the alignment position of the mounting holes of the first rod body and the second rod body, the length of the connecting rod 1 can be changed.
[0056] Optionally, the connecting rod 1 comprises a threaded sleeve and a threaded rod, which are threadedly connected, and can also achieve the technical effect of flexibly changing the length of the connecting rod 1.
[0057] Because the side surface of the connecting rod 1 is in hard contact with the valve stem 7 for a long time, the stress area of the side surface of the connecting rod 1 is seriously worn, which can reduce the service life of the connecting rod 1. Therefore, as shown inFigure 4 As shown in the figure, a reinforcing square plate 9 is welded on the force area on the two sides of the connecting rod 1, the reinforcing square plate 9 is a rectangular plate, and is perpendicular to the connecting rod 1, and is welded and fixed between the top surface of the connecting rod 1 and the back surface of the reinforcing square plate 9 through reinforcing ribs 10, and the bottom surface of the connecting rod 1 and the back surface of the reinforcing square plate 9 are also welded with the reinforcing ribs 10.
[0058] In this way, the reinforcing square plate 9 is in direct hard contact with the valve rod 7, thereby protecting the connecting rod 1 and prolonging the service life of the connecting rod 1.
[0059] It should be noted that the structure and number of the reinforcing ribs 10 are not specifically limited in the embodiment, as long as the reinforcing square plate 9 and the connecting rod 1 can be enhanced in connection strength.
[0060] In the description of the present application, it should be noted that the terms "upper", "lower" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0061] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "communication", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly communicated, or it can be indirectly communicated through an intermediate medium, or it can be the communication between two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise stated, the meaning of "multiple" is two or more.
[0062] The above is only the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
