Description

Manhole Frame Height Adjustable Type Valve Room

The present invention relates to a manhole frame height-adjustable valve chamber, and more particularly, the height of the manhole frame that connects the manhole located on the ground and the valve chamber located in the ground so that the height of the manhole frame can be adjusted through the height adjustment bundle. It relates to an adjustable valve chamber.

In general, a valve chamber is a facility made for easier and more convenient use and management of equipment such as valves or pumps installed to perform various functions among various pipe networks buried underground, and is connected to the ground through a manhole.

In many cases, such a valve chamber has a difference in distance from the ground after construction, so that the height of the manhole frame connecting the ground and the valve chamber can be adjusted. To this end, the conventional manhole frame is designed to adjust the height of the manhole frame by individually operated height adjusting means as in Patent Registration No. 10-1980040 (valve chamber), so that the height of each height adjusting means is adjusted uniformly. It is not easy, and since all the height adjustment means provided in plurality have to be adjusted, the height adjustment operation is very cumbersome and requires a lot of time.

Accordingly, a valve chamber capable of reducing the height adjustment time of the manhole frame and simplifying the adjustment operation is proposed by collectively operating a plurality of height adjustment means. As an example of such a valve chamber, the height adjustment of the manhole frame is easy One valve chamber (Registration Patent No. 10-0973229) is mentioned. As shown in FIG. 1, since this valve chamber can be rotated simultaneously by binding a plurality of screws 131 with a chain 135, it is possible to quickly and conveniently adjust the height of the manhole frame, but It is not easy to solve the sagging of the chain 135, and the maintenance of the chain 135 itself is very difficult, and it is very difficult to put it into practical use.

KR 10-0973229

The present invention is proposed to solve the problems of the conventional valve chamber as described above, and when a gap occurs between the manhole located on the ground and the valve chamber located in the ground, height adjustment for adjusting the height of the manhole frame By allowing a plurality of drive shafts provided in the bundle to be rotated collectively, not only can the height adjustment work be performed quickly and conveniently, but also by realizing the connection between the drive shafts for this through gear meshing, the durability of the height adjustment bundle The purpose is to improve the performance, and to improve the convenience according to maintenance and use.

In order to achieve this object, the present invention provides a housing that forms an outer body while forming a space therein; a manhole frame connecting the manhole and the housing, separated into a base and an elevating part, so that the height can be adjusted according to the distance between the housing and the manhole through the relative movement of the elevating part with respect to the base; and a height adjustment bundle installed on the periphery of the manhole frame to adjust the height of the manhole frame by a rotational operation of an operator; By doing so, it provides a manhole frame height-adjustable valve chamber that can adjust the height of the manhole frame only by manipulating any one of the drive shafts.

In addition, the height adjustment bundle, the case installed in the circumferential direction around the manhole frame; a plurality of the drive shafts mounted on the case to be rotatably evenly distributed in the circumferential direction; an interlocking gear unit gear-coupled to the plurality of driving shaft units so that when any one of the plurality of driving shaft units is rotated, the other driving shaft units also rotate in the same direction; and a screw transfer unit for lifting and lowering the lifting unit by relative rotation when any one of the driving shaft units is rotated in the forward and reverse directions by the operator.

In addition, the drive shaft portion, a drive shaft rotatably mounted to the case so that the operator can rotate in a forward and reverse direction; and a driven shaft having one end rotatably coupled to the case insertion end of the drive shaft, the other end being rotatably supported on the housing, and rotating in association with the rotation of the drive shaft. .

In addition, the interlocking gear unit is a driving gear formed in the case insertion end of the driving shaft; a ring gear circumferentially installed in the case so as to be externally engaged with the driving gear; and a driven gear mounted to rotate synchronously to the case insertion end of the driven shaft, and rotatably mounted in the case to be externally engaged with the ring gear.

In addition, the screw transfer unit, a transfer screw formed on the outer peripheral surface of the driven shaft; and an elevating bar having one end screwed to the transfer screw, the other end connected to the elevating unit, and elevating the elevating unit as the driven shaft rotates in a forward and reverse direction.

According to the manhole frame height-adjustable valve chamber of the present invention, even if any one of the drive shaft portions provided in the plurality of height adjustment bundles is operated, the screw transfer unit connected to all the drive shaft portions is a drive gear, a driven gear, and a ring gear. It can be operated simultaneously through the interlocking gear part of do.

In addition, since the rotational force applied to the drive shaft by the operator's rotational operation is transmitted to the screw transfer unit by gear engagement by the interlocking gear unit, the durability and maintenance performance of the power transmission unit can be further improved.

In addition, since the operator's rotational operation of the drive shaft and the drive gear is transmitted to the screw conveying unit through the ring gear, the driven gear, and the driven shaft in turn, the lifting bar of the screw conveying unit cannot rotate when lifting and lowering, causing rotational resistance in the driven shaft. However, since the driven shaft can freely rotate relative to the driving shaft, it is possible to further improve the stability of the device according to the lifting operation of the height adjustment bundle and the durability performance thereof.

Hereinafter, a manhole frame height-adjustable valve chamber according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown by reference numeral 1 in FIG. 2 , the valve chamber of the present invention largely includes a housing 3 , a manhole frame 5 , and a height adjustment bundle 7 .

Here, the housing 3 is a part constituting the body of the valve chamber 1, and as shown in FIG. 2, forms an internal space leading to the manhole 10 under the ground, and a normal operator works inside It is manufactured as a square or cylinder of a size that can secure enough space, and various conduits (P) pass through it.

The manhole frame 5 is a part connecting the manhole 10 and the valve chamber 1, and is interposed between the outer peripheral surface of the valve chamber 1 and the housing 3 and the manhole 10, as shown in FIG. 2 . As a bar, it has a cylindrical tube body, and is separated into a base 11 and an elevating unit 13 to adjust the overall height, and the elevating unit ( 13) to be able to ascend and descend. That is, when constructing the valve chamber 1 , by relatively moving the elevating unit 13 with respect to the base 11 , the elevating unit at the lower end of the base 11 is matched to the gap between the housing 3 and the manhole 10 . (13) The distance to the top, that is, the height of the manhole frame 5 can be adjusted.

The height adjustment bundle 7 is a part for adjusting the height of the manhole frame 5, and as shown in FIG. 3, any one of the plurality of driving shaft parts 23 installed on the circumference of the manhole frame 5 By manipulating the elevating unit 13 to elevate with respect to the base 11 , the height of the manhole frame 5 is adjusted. That is, the height adjustment bundle 7 is a plurality of drive shaft portions 23 to be described later in the interlocking gear portion 25, that is, the drive gear 41, the driven gear 45, and the gear mesh by the ring gear 43. By connecting and interlocking with each other, it is possible to elevate the entire drive shaft 23 only by operating any one of the plurality of drive shaft portions 23 , and thus adjust the height of the manhole frame 5 . be able to

To this end, the height adjustment bundle 7 is configured to include a case 21 , a drive shaft part 23 , an interlocking gear part 25 and a screw transfer part 27 again, as shown in FIGS. 3 to 5 . do.

Here, the case 21 is a receiving part for containing the gear part of the height adjustment bundle 7, and as shown in FIG. 4, is a ring-shaped cylinder installed around the manhole frame 5 in the circumferential direction, As shown in FIG. 3 , it consists of a housing body and a cover, and is connected on the outer peripheral surface of the housing 3 through the base part 31 . However, as shown in FIG. 5 , the base part 31 is formed by a guide rail 28 protruding inward in the radial direction on the inner circumferential surface of the outer wall 32 connected to the case 21 , the guide rail Reference numeral 28 has its inner end fitted into a locking groove 57 of a transfer nut 55 to be described later to prevent rotation of the transfer nut 55 .

In addition, the drive shaft portion 23 is a means for allowing the operator to rotate and lift the lifting portion 13 of the manhole frame 5 through the screw transfer portion 27, as shown in FIG. 4, 2 More than one piece passes through the case 21 and is mounted uniformly distributed in the circumferential direction of the manhole frame 5 . At this time, each drive shaft 23 is rotatably mounted with respect to the case 21, and can be formed in any shape as long as it can elevate the lifting unit 13 by rotating the screw transfer unit 27 as above. However, in this embodiment, as shown in FIG. 5 , it is composed of a driving shaft 33 and a driven shaft 35 again.

Here, the drive shaft 33 is a shaft portion that can be manipulated by the operator, and is rotatably mounted on the case 21 so that the operator can rotate the tip portion exposed to the outside of the case 21 in the forward and reverse directions. , In particular, as shown in FIG. 5 , the lower end, that is, the case 21 insertion end is fitted on the same central axis on the upper end of the driven shaft 35 , and is slidably rotatably supported by the driven shaft 35 . In addition, the driven shaft 35 is indirectly rotationally driven by the drive shaft 33 to operate the screw transfer unit 27 , and the upper end, that is, the case 21 insertion end, of the drive shaft 33 as above. The case 21 is slidably rotatably coupled to the insertion end, that is, the lower end. In addition, the lower end thereof is rotatably supported by a thrust bearing bush 37 or the like on the base portion 31 , that is, the housing 3 , as shown in FIG. 5 . Accordingly, the driven shaft 35 rotates in association with the rotation of the driving shaft 33 , thereby elevating the lifting unit 13 through the screw transfer unit 27 .

However, if any one of the plurality of driving shaft units 23 is rotated, the lifting unit 13 can be raised and lowered. By operating the corresponding screw transfer unit 27, the lifting unit 13 is raised and lowered together with the screw transfer unit 27 operated by the operator.

In addition, the interlocking gear unit 25 is linked with the drive shaft unit 23 operated as above by the operator so that the entire drive shaft unit 23 and the screw transfer unit 27 can lift the lifting unit 13 together. As a part, when rotating by manipulating any one of the plurality of drive shaft portions 23 , the other drive shaft portion 23 also serves to rotate in conjunction with each other in the same direction. In this way, in order to link the plurality of drive shaft portions 23, the interlocking gear portion 25 gear-couples each of the drive shaft portions 23 to each other, and as shown in FIGS. 3 to 5 , the drive gear ( 41 ), a ring gear 43 , and a driven gear 45 .

Here, the driving gear 41 is a gear member integrally formed with the upper driving shaft 33, and as shown in FIG. Formed on the bar, the rotational driving force of the drive shaft 33 is transmitted to the ring gear 43 by externally engaging with the ring gear 43 to be described later.

In addition, the ring gear 43 is a gear member that uniformly transmits the rotational force applied to the arbitrary drive gear 41 that is rotated by the operator to the entire remaining drive shaft 23, and as shown in FIG. 5, The bar is installed in the circumferential direction in the case 21 so as to be externally engaged with the driving gear 41, and is guided to turn in the circumferential direction along the guide protrusion 44 in the case 21, and a driven gear 45 to be described later. ) and the rotational force of the drive shaft 33 is transmitted to the driven shaft 35 by being engaged in circumscribed contact. Accordingly, the ring gear 43 rotates in the same direction with the drive shaft 23 that is directly operated even with the drive shaft 23 that is not directly rotated by the operator.

In addition, the driven gear 45 is a ring gear, that is, a gear member that transmits the rotational force transmitted from the driving shaft 33 to the screw transfer unit 27 through the driven shaft 35. As shown in FIG. 5, The case 21 insertion end of the driven shaft 35 to be adjacent under the driving gear 41 in the case 21 so as to be externally engaged with the ring gear 43, that is, the upper end of the case 21 is mounted on the same central axis, By being mounted on the periphery of the driven shaft 35 through a key combination or the like, it rotates synchronously with the driven shaft 35 . During synchronous rotation, the driving gear 41 and the driven gear 45 constitute the same central axis with the thrust bearing bush 47 so that they do not receive rotational force interference with each other. Therefore, the driven gear 45 is transmitted from the ring gear 43 The rotational force is transmitted to the screw transfer unit 27 through the driven shaft 35 .

In addition, the screw transfer unit 27 is a means for converting the rotational driving force transmitted from the driving shaft unit 23 and the interlocking gear unit 25 as described above into a lifting motion of the lifting unit 13, and any one of the driving shaft units ( 23) is rotated in the forward/reverse direction by the operator, the rotation of the transfer nut 55 is blocked by the guide rail 28 and moves up and down while rotating relative to the drive shaft 23 to elevate the elevating unit 13. A bar, as shown in FIG. 5 , is configured to include a transfer screw 51 and an elevating bar 53 .

Here, the transfer screw 51 is a screw portion formed on the outer peripheral surface of the driven shaft 35, and rotates together when the driven shaft 35 is rotated forward and reverse by the ring gear 43, and the transfer nut 55 is formed on the outer peripheral surface. The elevating bar 53 coupled through the etc. and the elevating unit 13 connected through the elevating bar 53 are elevated. At this time, since the rotation of the transfer nut 55 is inhibited by the guide rail 28, the vertical movement of the lifting bar 53 is induced while ascending and descending without rotating, that is, the lifting and lowering. However, the transfer screw 51 , that is, the driven shaft 35 receives the rotational reaction force acting from the lifting bar 53 and the lifting unit 13 through the transfer nut 55 , the rotation of which is blocked by the guide rail 28 . The relative rotation is freely coupled to the drive shaft 33 through the thrust bearing bush 47 so as not to directly transmit the transmission to the drive shaft 33 .

In addition, since the lifting bar 53 does not rotate and only ascends and descends along the transfer screw 51, when ascending, the transfer screw 51, that is, the driven shaft 35, is to be grabbed by a downward reaction, and the opposite descending When the driven shaft 35 is pushed up by an upward reaction, the driven shaft 35 is stably maintained in its position, as shown in FIG. A locking protrusion 49 interposed therebetween protrudes outward in the radial direction. That is, even if the driven shaft 35 is pressed up and down by the rotational reaction force of the elevating bar 53 as described above, it does not move up and down by the thrust bearing bush 47 and the locking protrusion 49 and maintains its original position.

In addition, the lifting bar 53 is a part that directly elevates the lifting unit 13 while ascending and lowering by the transfer screw 51 as above, as shown in FIG. The nut 55 is screw-coupled to the transfer screw 51 , and the other end, that is, the inner end thereof, is connected to the lifting unit 13 to raise and lower the lifting unit 13 according to the rotation of the transfer screw 51 . At this time, since the guide rail 28 as well as the lifting bar 53 and the lifting unit 13 cannot rotate, as mentioned above, the transfer nut 55 is the transfer screw 51 , that is, the driven shaft 35 . ) elevates when the forward and reverse rotation, but causes resistance to the rotation of the driven shaft 35, the driven shaft 35 rotates relative to the drive shaft 33, the drive gear 41 or the ring gear 43 In this way, the drive shaft 33 and the drive gear 41 are supported through the thrust bearing bush 47 .

Now, the operation of the valve chamber according to a preferred embodiment of the present invention will be described as follows.

The valve chamber 1 of the present invention, for example, when the distance from the outer circumferential surface of the housing 3 to the ground is longer than the set height of the manhole frame 5, the operator controls the lifting unit 13 through the height adjustment bundle 7 By raising it, the height of the manhole frame 5 can be increased so that the manhole 10 can be positioned in the correct position on the ground.

To this end, the operator initially selects one of the drive shaft portions 23 among the plurality of drive shaft portions 23 and rotates the drive shaft 33 in the direction of the arrow B in FIGS. 3 and 4 , for example. Accordingly, when the driving gear 41 rotates, the ring gear 43 rotates in the direction of the arrow C in FIG. The driven gear 45 of the drive shaft 23 also rotates in the direction of the arrow D of FIG. 4 .

In this way, when all the driven gears 45 rotate in the direction of the arrow D, all the driven shafts 35 rotate in the same direction at the same time to lift the lifting bar 53 at the same time. Accordingly, the height of the lifting unit 13 is increased, as shown in FIG. 6 , and thus a series of operations to increase the height of the manhole frame 5 can be simply and quickly finished.
