Description

  The present invention relates to a damper opening adjusting handle operating device.

  Generally, in factories and the like, an air conditioning duct is provided near the ceiling in a building, a damper is provided in the middle of the air conditioning duct, and the air volume from the air outlet of the air conditioning duct is adjusted by adjusting the opening of the damper. To be adjusted.

  Since the damper is installed at a high place, when the operator performs the air volume adjustment work, the height adjustment of the damper is adjusted by using a work vehicle or a scaffold, or climbing on a standing horse or stepladder. You must reach out to the position of the handle for adjustment.

  However, to use an aerial work platform, assembled scaffolding, or standing horses or stepladders, it is necessary to have a suitable place, and it is troublesome to carry in and out of them. Had a problem.

  For this reason, there is a conventional one disclosed in, for example, Patent Document 1, which is, as shown in FIG. 5, flanged to an air-conditioning duct (not shown) immediately below the ceiling slab 1 of a building such as a factory. The casing 3 of the damper 2 for adjusting the air volume to be joined is disposed, and the damper main body 4 is pivotally supported inside the casing 3 so as to be rotatable around the shaft 4a. An opening adjustment shaft 6 suspended from the attached gear box 5 is connected via a worm gear incorporated in the gear box 5, and an opening adjustment handle 7 is integrally formed at the lower end of the opening adjustment shaft 6. When the opening of the damper 2 is adjusted, the connecting portion 10 formed at the tip of the operation tool 9 held by the operator on the floor from the inspection port 8a of the interior ceiling 8 is provided. Insert, In the state of being engaged with the opening adjustment handle 7, the opening adjustment handle 7 is rotated by turning the rotation operation portion 11 formed at the base end portion of the operation tool 9. is there.

  As shown in FIG. 6, the opening adjustment handle 7 includes a handle rod 7a extending radially from the opening adjustment shaft 6, and a ring 7b integrated around the handle rod 7a. Further, the connecting portion 10 of the operation tool 9 includes a horizontal rod 10a extending to both sides perpendicular to the tip of the operation rod 12, a rising portion 10b rising integrally from both ends of the horizontal rod 10a, and an upper end of the rising portion 10b. To the circumferential direction of the operating rod 12 and a hook-shaped piece 10c bent into a hook shape, respectively, and the rotation operating portion 11 of the operating tool 9 has a crankshaft shape.

  In addition, although it is a thing different from the damper installed in a high place, as what shows the general technical level relevant to opening and closing of the valve installed in the ground, patent document 2 or patent document 3 is, for example is there.

Japanese Patent No. 3456304 JP 2009-222205 A Japanese Utility Model Publication No. 5-27460

  By the way, the opening adjustment handle 7 is not limited to the handle 7a provided inside the ring 7b as shown in FIG. 6, but, for example, as shown in FIG. There is also a dish-shaped opening adjustment handle 7.

  However, with the operation tool 9 disclosed in Patent Document 1, the connecting portion 10 cannot be engaged with the dish-shaped opening adjustment handle 7 as shown in FIG. In addition, it has a drawback that it is impossible to adjust the opening degree of the damper 2.

  Further, the one described in Patent Document 2 is a state in which a fitting member or an engaging member is fitted to a stem (not shown) of a stem type valve or a rod-like portion of a handle (corresponding to the handle rod 7a). Therefore, when applied to the damper 2, it is difficult to deal with the dish-shaped opening adjustment handle 7 as shown in FIG. 7 when applied to the damper 2. It was impossible to adjust the opening degree of the damper 2.

  Furthermore, the device described in Patent Document 3 does not operate the opening adjustment handle 7 of the damper 2 but opens and closes the valve with the fitting portion fitted to the valve stem head of the valve. It is like that. Although it is possible to engage the reverse funnel-shaped guide described in Patent Document 3 with the opening adjustment handle 7 of the damper 2, the guide is only used to connect the valve stem head to the fitting portion. Since it is for guiding to be slid, it is inevitable that slipping occurs, and it is difficult to rotate the opening adjustment handle 7.

  In view of such circumstances, the present invention provides a damper opening that can reliably adjust the opening of the damper by rotating the opening adjustment handle without using an aerial work vehicle, a scaffold, a standing horse, or a stepladder. It is intended to provide a degree adjusting handle operating device.

The present invention provides an opening adjustment handle operating device for a damper that is installed at a high place and attached to the lower end of an opening adjustment shaft in which an opening adjustment handle extends in the vertical direction.
A rod-like body having a length that reaches the opening adjustment handle in a state held by an operator on the floor;
A funnel-shaped holding member attached to the tip of the rod-like body and having an inner peripheral surface engageable with the outer periphery of the opening adjustment handle;
A damper opening adjustment handle operating device comprising a seat member that is attached to an inner peripheral surface of the holding member and that increases a frictional force with respect to the opening adjustment handle.

  According to the above means, the following operation can be obtained.

  As described above, by attaching a funnel-shaped holding member to the tip of the rod-shaped body, the opening adjustment comprising the handle rod extending radially from the opening adjustment shaft and the ring integrated around the handle rod. The holding member can be engaged not only with the handle but also with the dish-shaped opening adjustment handle, and the inner peripheral surface of the holding member has a frictional force against the opening adjustment handle. Since the sheet member to be raised is attached, it is possible to avoid the occurrence of slipping, and the opening adjustment handle can be reliably rotated by turning the rod-shaped body.

  And since the said holding member is funnel-shaped, even if the outer diameter of the said opening adjustment handle is somewhat different, it becomes possible to cope with one holding member without preparing a plurality of types of holding members. At the same time, even when the opening adjustment handle is at a high position and is not easily visible from the inspection port of the interior ceiling, the centering for engaging with the opening adjustment handle can be easily performed.

  Further, even if the rod-like body is not arranged on the axial extension line of the opening adjustment shaft but is inclined to some extent, the holding member is interposed on the outer periphery of the opening adjustment handle via the seat member. The opening adjustment handle can be rotated.

  In the damper opening adjusting handle operating device, it is preferable to form a rotation assist means at the base end of the rod-shaped body.

  When the rotation assisting means is a non-slip grip tape that is wound around the outer periphery of the base end of the rod-shaped body, it becomes possible for an operator to firmly grip the rod-shaped body, and to reliably perform an operation of turning the rod-shaped body .

  In addition, the rotation assisting means can be a handle that protrudes in the radial direction at the base end portion of the rod-shaped body, and in this way, the operator firmly grasps the rod-shaped body while holding the handle. In addition, since the rod-like body can be pushed up more strongly by the handle, the frictional force of the seat member with respect to the opening adjustment handle can be further increased. In addition, the force required for the operator to perform the operation of turning the rod-shaped body is less than that required when the operator simply grips the outer periphery of the rod-shaped body, which is effective in improving operability.

  Furthermore, the rotation assisting means may be a crank handle that is bent at the base end of the rod-shaped body, so that an operator can firmly hold the rod-shaped body by the crank handle, and Since the rod-like body can be pushed up more strongly by the crank handle, the frictional force of the seat member with respect to the opening adjustment handle can be further increased. In addition, the force required for the operator to perform the operation of rotating the rod-shaped body is smaller than that required when the operator simply grips the outer periphery of the rod-shaped body, so that the operation of rotating the rod-shaped body can be performed more efficiently.

  According to the damper opening adjustment handle operating device of the present invention, the opening adjustment handle is securely rotated by rotating the opening adjustment handle without using an aerial work vehicle, a scaffold, a standing horse or a stepladder. An excellent effect can be achieved.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  1 and 2 show an embodiment of a damper opening adjusting handle operating device according to the present invention. In the figure, parts denoted by the same reference numerals as those in FIGS. The structure of this embodiment is the same as that of the conventional one shown in FIGS. 5 to 7, but the feature of this embodiment is that it is opened by the operator on the floor as shown in FIGS. A funnel-shaped holding member 14 whose inner peripheral surface can be engaged with the outer periphery of the opening adjusting handle 7 is attached to the tip of a rod-like body 13 having a length reaching the degree adjusting handle 7. The sheet member 15 which raises the frictional force with respect to the opening adjustment handle 7 is attached to the inner peripheral surface.

  The sheet member 15 is made of a material such as rubber and is attached to the inner peripheral surface of the holding member 14 with an adhesive such as a two-type mixed epoxy resin adhesive.

  Since the outer diameter of the opening adjustment handle 7 is normally about φ100 [mm], the inner diameter of the opening end of the holding member 14 to which the sheet member 15 is attached is φD = φ150 as shown in FIG. It is set to about [mm], and the spread angle of the holding member 14 can be set to about θ = 60 °. However, these numerical values are only a guide and are not limited to those values.

  The rod-shaped body 13 uses a vinyl chloride tube or an aluminum tube, and can be set to a length of about 2500 to 4000 [mm] according to the height position of the opening adjustment handle 7. .

  An anti-slip grip tape 16 a that is wound around the outer periphery of the base end portion of the rod-like body 13 is formed as a rotation auxiliary means 16 at the base end portion of the rod-like body 13.

  Next, the operation of the above embodiment will be described.

  As described above, by attaching the funnel-shaped holding member 14 to the tip of the rod-shaped body 13, the handle rod 7a extending radially from the opening adjustment shaft 6 as shown in FIG. 6, and the handle rod 7a The holding member 14 is engaged not only with the opening adjustment handle 7 including the ring 7b integrated in the periphery but also with the dish-shaped opening adjustment handle 7 as shown in FIG. In addition, since the seat member 15 for increasing the frictional force with respect to the opening adjustment handle 7 is attached to the inner peripheral surface of the holding member 14, it is possible to avoid the occurrence of slipping, and the rod 13 The opening adjustment handle 7 can be reliably rotated by turning. Incidentally, since the sheet member 15 is made of a material that is elastically deformed like rubber, by being pressed against the opening adjustment handle 7 and bending, the contact area with the opening adjustment handle 7 is increased, and the frictional force is increased. It will increase more.

  And since the said holding member 14 is made into the funnel shape, even if the outer diameter of the said opening adjustment handle 7 is a little different, it is one holding member 14 without preparing multiple types of holding members 14 In addition to being able to cope, even when the opening adjustment handle 7 is at a high position and is not easily visible from the inspection port 8a of the interior ceiling 8, the centering for engaging with the opening adjustment handle 7 can be easily performed. .

  Even if the rod-like body 13 is not arranged on the extension line of the opening adjustment shaft 6 so as to be completely coincident, but is inclined to some extent, the holding member 14 is placed on the outer periphery of the opening adjustment handle 7. If the contact is made via the seat member 15, the opening adjustment handle 7 can be rotated.

  An anti-slip grip tape 16 a wound around the outer periphery of the base end portion of the rod-like body 13 is formed as a rotation assisting means 16 at the base end portion of the rod-like body 13, so that the operator securely holds the rod-like body 13. And the operation of turning the rod-like body 13 can be performed reliably.

  As shown in FIG. 3, the rotation assisting means 16 can be a handle 16b projecting in the radial direction at the proximal end portion of the rod-like body 13, and the operator grips the handle 16b. In this state, the rod-like body 13 can be firmly grasped, and the rod-like body 13 can be pushed up more strongly by the handle 16b, so that the frictional force of the seat member 15 against the opening adjustment handle 7 can be further increased. It becomes possible. In addition, since the force required for the operator to perform the operation of turning the rod-shaped body 13 is smaller than when the operator simply grips the outer periphery of the rod-shaped body 13, it is effective in improving the operability.

  Further, as shown in FIG. 4, the rotation assisting means 16 may be a crank handle 16c that is bent at the base end portion of the rod-shaped body 13. In this case, an operator can move the rod-shaped body by the crank handle 16c. 13 can be firmly gripped, and the rod-like body 13 can be pushed up more strongly by the crank handle 16c, so that the frictional force of the seat member 15 against the opening adjustment handle 7 can be further increased. In addition, since the force required for the operator to perform the operation of rotating the rod-shaped body 13 is smaller than when the operator simply grips the outer periphery of the rod-shaped body 13, the operation of rotating the rod-shaped body 13 can be performed more efficiently. It becomes.

  Thus, the opening adjustment handle 7 can be rotated to reliably adjust the opening of the damper 2 without using an aerial work vehicle, a scaffold, a standing horse, or a stepladder.

  It should be noted that the damper opening adjusting handle operating device of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
