Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter lid upper machine for attaching and detaching a gutter lid which is disposed at an upper end opening of a gutter and closes the gutter lid.

[0002]

[Prior art]

 As shown in FIG. 11, in the side groove 55 provided on the road side, a concrete side groove cover 50 integrally formed in a rectangular thick plate shape is provided on the side walls 55a, 55a of the side groove 55 from the viewpoints of falling prevention. It is customary to lay the lid receiving portions 56, 56 formed in the above in order in a line in the upper end opening of the side groove 55 and close the lid.

By the way, it is necessary to regularly clean the inside of the gutter 55 in order to maintain drainage. In this case, the gutter lids 50, 50, ... It is necessary to remove them one by one and install them again after cleaning is completed. In order to perform such removal and installation work of the gutter lid 50, the gutter lid 50 is provided with recesses 51, 51 in the widthwise central portions of the front end face 50a and the rear end face 50b thereof, respectively. When installed along the groove direction of the lid 50, a work opening 52 of a predetermined size is formed by the recesses 51, 51 between the adjacent gutter lids 50, 50 (note that the gutter lid 50 Depending on the type of the above, the recess 51 may be provided on only one of the front end face 50a and the rear end face 50b).

Therefore, when the worker manually removes and installs the gutter lid 50, the operator should insert his or her hand into the work openings 52, 52 provided at the front and rear of the gutter lid 50, respectively. Although good, in practice, it is desirable to do this mechanically because the gutter lid 50 is relatively heavy.

Various devices have been developed to meet such demands. For example, a holder for holding the gutter cover 50 between its front end face 50a and its rear end face 50b is provided with an arm and a wheel of an appropriate length, and after holding the gutter cover 50 with the holder, the arm is tilted and the lever is held. There is known a device in which the gutter lid 50 is lifted from its one end side by the action, and thereafter, the gutter lid 50 is moved to a predetermined position by wheels.

[0006]

[Problems to be solved by the device]

 However, in the case of adopting such a method of inclining the gutter cover 50 and attaching / detaching it to the gutter 55 side, the turning locus of the end portion of the gutter cover 50 on the upper side in the inclination direction is located forward of the position in the installed state. Due to the approaching, removal of either one of the front and rear ends of the gutter lid 50 when it is open (that is, when one of the adjacent gutter lids 50, 50 has already been removed). Can be used only for installation work. That is, when only one gutter lid 50 is removed from the gutter lids 50, 50, ... which are sequentially installed in a row, or conversely, only one gutter lid 50 is left at the end. In the case where it is installed in the space opened between the gutter lids 50 and 50, it is necessary to move this in the vertical direction, and therefore the tilting device as described above cannot be applied.

Therefore, in the work that requires the vertical movement of the gutter lid 50, for example, the tilting device as described above is used, and the device itself is held by the holder while holding the gutter lid 50. To move the gutter cover 50 in the vertical direction by using a manual jack holder mechanism to support it at the center of the grounding leg installed across both sides of the gutter 55. Then, the method of removing or installing this is adopted.

However, in the former case, the working weight is the weight of the gutter lid 50 plus the weight of the device, and in addition, especially when the gutter lid 50 is removed, the gutter lid 50 and the gutter 55 are removed. Since the gutter lid 50 is in a state of being almost fixed due to sand or the like that has penetrated into the gap, the labor burden on the worker is excessive, and in some cases two workers may be required. In any case, the work efficiency is inevitable.

Further, in the latter case, since the vertical movement of the gutter lid 50 is performed by the manual jack, the labor burden on the worker is reduced in this work as compared with the former case, but the first gutter groove. Since the removal / installation work of the lid 50 (ie, vertical movement work) and the removal / installation work of the second and subsequent gutter lids 50 (ie, tilt movement work) are separate operations, a dedicated machine is provided for each work. However, it is difficult to carry out the work quickly, and therefore this method is inevitably inferior in work efficiency.

Further, in the conventional device, the dimension of the holder holding the gutter lid 50 is fixedly set, and when applied to the gutter lids 50 having different dimensions, the dimension is exclusively set. The holder had to be prepared and used depending on the type of the gutter lid 50, and the operation was complicated.

Therefore, the invention of the present application provides a gutter lid upper machine capable of improving the work efficiency and labor saving in a series of work of removing and installing the gutter lid, and also increasing the versatility thereof. It was made for the purpose.

[0012]

It can be done if possible.

[0021]

[Effect of device]

 Therefore, according to the gutter lid lifting machine of the inventions of the present application, a series of work of removal / installation including vertical movement of the gutter lid can be performed continuously by a single gutter lid lifting machine. Effective use of equipment and work efficiency compared to the case where dedicated equipment is used for each work and preparation work is required for each work, such as when work is performed separately using different equipment Can be improved.

Further, since the vertical jacking operation or the vertical embedding operation of the gutter lid that cannot use the leverage effect is performed by using the hydraulic jack that can obtain a large thrust, the worker can easily operate the hydraulic pressure. Vertical removal or vertical embedding of the gutter lid can be easily performed only by jacking.For example, as compared with the case where these operations are performed manually or the case where a manual jack is used, Since the labor burden of each worker can be reduced and a single worker can perform a series of removal and installation work including vertical extraction and vertical embedding, work efficiency can be improved and labor cost can be reduced by labor saving. In particular, such an effect is that the gutter lid is in a state close to sticking due to sand or the like that has bitten between the gutter lid and the gutter, and a larger pulling force is required. In some cases, it becomes more remarkable.

Further, in addition to such a basic effect, in particular, when the distance between the pair of holding members such as the gutter lid upper machine according to claim 2 can be adjusted, various types having different length dimensions are provided. If the distance between the gutter lid and the latch claw in the extending direction of the holding member is adjustable, as in the upper gutter lid machine of claim 3, various types of gutter lids having different thickness dimensions are provided. In addition, since the same gutter top machine can be applied as it is, the versatility of the gutter top machine is improved and extended compared to the case where a special attachment is required for each different size. In addition, it is expected that the work cost will be reduced by the effective use of the gutter top device.

A chain fixing ring 40 is provided at the tip of the inner tubular member 32, and the other end of the chain 14 whose one end is fixed to the chain fixing ring 40 is connected to the middle portion 10b of the elevating post 10. Arbitrary chain rings can be selectively attached to and detached from the protruding chain hooks 13. By adjusting the length of the chain 14, the chain 14 acts so as to regulate the maximum extension amount of the hold arm 30 in the state of being set to the regulation position.

The movable holding member 36 constitutes a pair of holding members within the scope of the utility model registration claim together with the fixed holding member 35, and like the fixed holding member 35, One end 36a of the holding arm 38 is fixed to the tip of the inner cylindrical member 32 of the above-mentioned arm 30, with the other end 36b formed with the pawl 38 facing toward the side. In the state where the holding arm 30 is set to the restricted position, the fixed holding member 35 and the movable holding member 36 have their hooking claws 37 and 38 located at the same height and are opposed to each other. The relative relationship is set such that the facing side surfaces 35c, 36c are parallel to each other.

The vertical gap between the holding claws 37 and 38 of the fixed holding member 35 and the movable holding member 36 and the hold arm 30 which face each other is set to be the gutter cover upper machine of this embodiment. Of the plurality of types of gutter lids to which Z is applied, the dimension is set to be larger than the thickness dimension of the gutter lid having the maximum thickness by a predetermined dimension. Further, the distance dimension between the fixed holding member 35 and the movable holding member 36 is adjusted to be increased or decreased by expansion and contraction of the hold arm 30, and the distance adjustment range is at least on the gutter lid of this embodiment. Among a plurality of types of gutter lids to which the machine Z is applied, the length dimension between the front and rear end faces can be adjusted within the range of the length dimension of the smallest and the length dimension of the largest.

Here, the relationship between the ascending / descending state of the ascending / descending post 10 and the expanding / contracting state of the hydraulic jack 16 is set as follows. That is, first, when the hydraulic jack 16 is in the most extended state (the state shown by the chain line in FIG. 1), the rod 17 thereof is engaged with the jack receiving portion 15 of the elevating post 10 so that the elevating post 10 is post-guided. 1, the lower ends of the hooking claws 37, 38 of the holding members 35, 36 are both in the grounding state, and the grounding point of the wheel 4 and the grounding point of the grounding leg 5 (grounding portion). (The lower end surface of 5b), it is positioned at almost the same height (immediately, the ground position), while the hydraulic jack 16 is in the most contracted state (the state shown by the solid line in FIG. 1), the lifting post 10 is moved. Moves down until the jack receiving portion 15 comes into contact with the rod 17 in the contracted state and further downward movement is restricted. At the lowering position of the elevating post 10, the holding members 35, 36 project downward from the ground position by a predetermined dimension, and the projecting amount is set so that the gutter lid lifting machine Z of this embodiment is applied. Of the plural types of gutter lids, the thickness dimension of the gutter lid 50 having the maximum thickness is set to be larger by a predetermined dimension.

Further, an adjusting bolt 41 having a predetermined length is screwed into the inner cylindrical member 32 of the hold arm 30 while vertically penetrating the inner cylindrical member 32. By adjusting the increase / decrease, the vertical distance between the contact plate 42 attached to the lower end of the adjusting bolt 41 and the 37, 38 of the holding members 35, 36 can be increased / decreased. That is, in this embodiment, the adjusting bolt 41 corresponds to the adjusting means in the scope of claims for utility model registration.

Description of Operating State Next, the removal / installation work of the gutter lid 50 using the gutter lid upper machine Z will be described in the order of work with reference to FIGS. 4 to 10.

At the time of cleaning the gutter 55, first, a specific gutter lid 50 is vertically pulled out from a gutter lid row in which the gutter lids 50, 50, ... There is a need. In this case, as shown in FIG. 4, with the hydraulic jack 16 reduced, the gutter lid upper unit Z is moved to the position of the specific gutter lid 50 to be removed, and the pair of holding members 35, 36 is made to correspond to the working openings 52, 52 which are opened on both front and rear sides of the specific gutter lid 50, and the wheels 4, 4 are placed on the gutter lid 50 adjacent to the specific gutter lid 50, and each grounding leg. 5 and 5 are appropriately swung from the stored position to the maximum swing position side, and these are grounded to the lateral positions of the specific gutter lid 50 (for example, the positions of the side walls 55a and 55a of the gutter 55 shown in FIG. 11). .

Here, the retaining claws 37, 38 of the holding members 35, 36 correspond to the working openings 52, 52, respectively, so that movable parts such as the elevating post 10, the hold arm 30 and the like are separated. Since there is no support for this, it falls by its own weight, and as shown in FIG. 5, the above-mentioned holding members 35, 36 project to the lower side of the gutter lid 50 through the above-mentioned working openings 52, 52. (Finally, the jack receiving portion 15 of the elevating post 10 can be lowered until it comes into contact with the rod 17 of the hydraulic jack 16.).

Next, as shown in FIG. 6, the gutter lid upper unit Z is moved forward as a whole so that the side surface 35 c of the fixed holding member 35 is brought into contact with one end surface of the gutter lid 50, and The arm 30 is contracted to bring the side surface of the movable holding member 36 into contact with the other end surface of the gutter lid 50. In this state, the tension of the chain 14 is adjusted to restrict the extension of the hold arm 30. After that, the lifting post 10 is manually pulled up, or the lifting post 10 is pulled up by extending the hydraulic jack 16, so that the hooks 37 and 38 are engaged with the front end corner portion 50e of the gutter lid 50 and the rear end. At the same time as being hooked on the end corners 50f, the adjusting bolt 41 is screwed in this state to bring the contact plate 42 close to and face the upper surface 50c of the gutter lid 50.

This completes the work of holding the gutter lid 50. In this case, the space between the holding members 35 and 36 in the lengthwise direction of the gutter lid 50 is adjusted by the hold arm 30, and the space between the gutter lid 50 on the upper surface 50c side in the thickness direction of the gutter lid 50 is adjusted. Since the contact plate 42 of the gutter 41 adjusts each of them, the holding state of the gutter lid 50 is accurate and reliable, and the operational reliability is improved. It can be easily applied to various types of gutter lids 50 and its versatility is enhanced.

Next, in this state, the hydraulic jack 16 is extended, or the extension is reopened to the maximum extension position. Then, as shown in FIG. 7, since the elevating post 10 rises, the gutter lid 50 held by the holding members 35 and 36 is integrally pulled up vertically upward, and finally the gutter 55. It is taken out from the lid receiving portion 56 of the above.

After that, as shown in FIG. 8, the elevating post 10 is tilted rearward to release the grounding state of each of the grounding legs 5 and 5 so that only the wheels 4 and 4 come into contact with each other. In the state, move it to a predetermined position. Then, as shown in FIG. 9, with the gutter lid 50 positioned on the receiving members 58, 58 separately arranged, the elevating post 10 is raised forward from its tilted state. In this case, when the raising operation of the elevating post 10 is further performed from the state in which the receiving member 58 on the front side is in contact with the portion of the side groove lid 50 close to the latch claw 37, the receiving force from the receiving member 58 is received. The hold arm 30 is pivotally displaced upward about the pivot shaft 33, the parallel state of the fixed holding member 35 and the movable holding member 36 is broken, and the latch claws 37 and 38 are opened at the same time. As the chain 14 sags, the extension restricting action on the hold arm 30 is released and the hold arm 30 extends, so that the distance between the fixed holding member 35 and the movable holding member 36 increases. As a result, the latching claws 37, 38 on the front end corner portion 50e and the rear end corner portion 50f of the gutter lid 50 are released, and the gutter lid 50 automatically moves to the gutter lid upper machine Z side. It will be detached from this and placed on the receiving members 58, 58.

As described above, since the vertical pulling-out operation of the gutter lid 50 is performed by the thrust of the hydraulic jack 16, the gutter lid 50 is vertically pulled out. As a result, the labor burden on the workers is extremely small, and the labor can be saved and the work efficiency can be improved.

When the removal of the first gutter lid 50 is completed as described above, a large space is created in front of the second gutter lid 50 as shown in FIG. The gutter lids 50, 50, ... Can be removed by inclining them as in the conventional case. Immediately after that, as shown in FIG. 10, with the hydraulic jack 16 contracted, the gutter lid upper unit Z is rolled with the wheels 4 and 4 while tilting backward, and this is installed on the second gutter lid 50. It is moved to the position, and the hook 37 of the fixed holding member 35 is made to face the working opening 52 between it and the third gutter lid 50. In this case, the chain 14 and the adjusting bolt 41 are maintained in the initially adjusted state.

In this state, when the elevating post 10 is gradually raised forward, the fixed holding member 35 next enters the working opening 52, and the movable holding member 36 gradually moves to the upper surface of the gutter lid 50. It approaches 50c and abuts against it. When the raising / lowering post 10 is further raised, the hold arm 30 is rotated upward from its restricted position, the parallel state between the fixed holding member 35 and the movable holding member 36 is broken, and the distance between the respective hooks 37, 38 is reduced. When the chain 14 sags, the hold arm 30 extends and the gap between the fixed holding member 35 and the movable holding member 36 increases, which causes the movable holding member 36 to move toward the end of the gutter lid 50. The part enters the lower side of the gutter lid 50 with the part wrapped around from above. After that, when the elevating post 10 is raised vertically, the chain 14 is tensioned, the extension of the hold arm 30 is restricted, and the second gutter lid 50 is fixed by the fixed holding member 35 and the movable holding member 36. It will be held (that is, the state shown in FIG. 6). Therefore, after that, as shown in FIG. 8, the elevating post 10 may be pulled backward as it is, and the gutter lid 50 may be moved to a predetermined position by the wheel 4. The same applies to the third and subsequent gutter lids 50.

Further, when the cleaning of the gutter 55 is completed, it is necessary to install the removed gutter lids 50, 50, ... Again on the gutter lid 50. In this case, the work procedure opposite to the above-described removal procedure is performed. The procedure can be performed in the same way as when it was removed, and its explanation is omitted here.

As described above, in the gutter lid upper device Z of this embodiment, all the removal / installation operations including the vertical removal of the gutter lid 50, the vertical embedding, and the movement of the gutter lid 50 after the removal are performed as one unit. It can be continuously and labor-savingly performed by the above-mentioned gutter lid lifting machine Z, and its working efficiency is significantly improved compared to the conventional model.

Although the height dimension of the grounding leg 5 in the above-described embodiment is fixedly set, in another embodiment of the present invention, for example, a screw-type screw is attached to the lower end of the grounding leg 5. A height adjusting member may be provided so that the height of each grounding leg 5, 5 can be adjusted separately. According to such a configuration, even when the ground height at the working position is different between the left and right, the height of the grounding legs 5, 5 is adjusted so that the elevating post 10 is oriented substantially vertically. Since the gutter lid upper machine Z can be installed in this state to perform work, operability or safety in work can be ensured. For the same reason, not only the grounding leg 5 but also the pair of casters 3, 3 are respectively provided with height adjusting mechanisms so that the vertical distance between the wheel 4 and the base material 2 is individually adjusted. It may be possible to adjust each.
