[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter lid lifting machine for attaching and detaching a gutter lid which is placed at an upper end opening of a gutter and closes the lid.

[0002]

2. Description of the Related Art As shown in FIG. 11, in a side groove 55 provided on a road side, a concrete side groove cover 50 integrally formed in a rectangular thick plate shape is provided on both side walls 55a of the side groove 55 in order to prevent falling. Lid receiving portions 56, 56 formed on the upper ends of the
It is usual that the upper end opening of the side groove 55 is lined up sequentially in a line in a state of being hooked on the side groove 55 and the lid is closed.

By the way, the inside of the side groove 55 needs to be cleaned regularly in order to maintain drainage.
In this case, the gutter covers 50, 50,
・ ・ It is necessary to remove one by one and install it 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, the adjacent side groove lids 50,
A work opening 52 of a predetermined size is formed by these recesses 51, 51 between the 50 (depending on the type of the gutter lid 50, the recess 51 may be either the front end face 50a or the rear end face 50b). Some are only provided on one side).

Therefore, when the worker manually removes and installs the gutter lid 50, the operator may insert his or her hand into the working openings 52, 52 provided in the front and rear of the gutter lid 50. However, in practice, since the gutter lid 50 is relatively heavy, it is desirable to do this mechanically.

Various devices have been developed to meet such demands. For example, the gutter lid 50 is attached to the front end surface 5
0a and the rear end surface 50b are provided with a holder provided with an arm and a wheel of an appropriate length, and after holding the gutter lid 50 by the holder, the arm is tilted and the gutter lid 50 is held by one end side of the gutter lid 50. There is known a device which is lifted from a car and then moved by wheels to a predetermined position.

[0006]

However, in the case of adopting the method of inclining the gutter cover 50 and attaching / detaching it to the side groove 55 side in this way, the turning locus of the end of the gutter cover 50 on the upper side in the inclination direction is set. Since it approaches the front of the position in the state, one of the front and rear ends of the gutter lid 50 is in the open state (that is, one of the adjacent gutter lids 50, 50 has already been removed). Can be used only for removal / 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 the lid 50 is installed in a space opened between the lids 50, it is necessary to move the lid 50 in the vertical direction. Therefore, the tilting device as described above cannot be applied.

Therefore, when the vertical movement of the gutter lid 50 is required, for example, the tilting device as described above is used, and the device itself is vertically held by the holder while holding the gutter lid 50. Direction, or by supporting the center part of the grounding leg installed on both sides of the side groove 55 through a manual jack holder mechanism, and moving the side groove lid 50 in the vertical direction by the manual jack. The method of removing or setting up is adopted.

In the former case, however, the working weight is the sum of the weight of the gutter lid 50 and the weight of the device, and particularly when the gutter lid 50 is removed, the gutter lid 50 and the gutter 5 are removed.
Since the gutter lid 50 is in a state of being almost fixed due to sand or the like that has bitten into the gap with 5, the labor burden on the worker is excessive, and in some cases two workers are required. In any case, the work efficiency is inevitably low and inferior.

Further, in the latter case, since the vertical movement of the gutter lid 50 is carried out by the manual jack, the labor burden on the operator is reduced in this work as compared with the former case, but the first gutter lid is carried out. Removal and installation work of 50
(I.e., vertical movement work) and removal / installation work of the second and subsequent gutter lids 50 (i.e., tilt movement work) are separate works. Therefore, a dedicated machine is used for each work and separately. Preparatory work is required, and quick work is difficult. Therefore, even in this method, work efficiency is inevitably low.

Further, in the conventional device, the gutter lid 5
When the size of the holder that holds 0 is fixedly set, and when it is applied to the gutter lid 50 having different sizes, a holder dimensioned for that is prepared, and this is used as the type of the gutter lid 50. Must be replaced and used accordingly,
The work was complicated.

Accordingly, 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 operations for removing and installing the gutter lid, and also increasing the versatility thereof. It was made for the purpose.

[0012]

As a concrete means for solving such a problem in the invention of the present application, in the invention of claim 1, the wheel and the grounding leg are provided, and in a mounting state in which both are grounded. Is a support mechanism capable of supporting a downward load and allowing movement by rolling the wheels while only the wheels are in contact with the ground, and an elevating post supported so as to be able to move up and down with respect to the support mechanism. And an elevating mechanism provided between the elevating post and the supporting mechanism, and a hydraulic jack for elevating and lowering the elevating post by the expansion and contraction of the elevating post, and a lower end portion of the elevating post with a gutter lid hook at a lower end thereof. A pair of holding members, which are provided with latching claws for stopping and are arranged to face each other in a substantially parallel manner at a predetermined interval, and the extending direction of the pair of holding members is substantially parallel to the elevating direction of the elevating post and the elevating post It is characterized in that a holding mechanism which way composed may embrace at its ends a groove cover between the pair of holding members is attached as Naru can hold the relative position.

According to a second aspect of the present invention, in the gutter lid upper device according to the first aspect, the pair of holding members of the holding mechanism are connected via an extendable arm, and the extension and contraction of the arms is adjusted to adjust the extension. The distance between the pair of holding members is adjustable, and a rope member is stretched between the tip of the arm and the elevating post at a predetermined inclination angle with respect to the extending and contracting direction of the arm. There is.

According to a third aspect of the invention, in the gutter lid upper device according to the first aspect, the holding mechanism increases or decreases the distance between the pair of holding members and the hooking claw in the extending direction. It is characterized by having an adjusting means.

[0015]

With each of the inventions of the present application, the following actions can be obtained by adopting such a configuration.

According to the first aspect of the present invention, the pair of holding members attached to the lower ends of the lifting posts by moving the lifting jack up and down by extending and retracting the hydraulic jack while the wheels and the grounding feet are grounded are provided. Since the lifting post is moved in the vertical direction, the lifting operation of the pair of holding members is performed only by the expansion / contraction operation of the hydraulic jack to remove the gutter lid by vertical extraction, and the pair of holding members are removed. It is possible to perform installation work by vertically lowering the gutter lid and vertically embedding it.

When one side is in the open groove state, the pair of holding members can hold the relative position with respect to the elevating post regardless of the tilting operation of the elevating post. The pair of holding members are always kept in an appropriate state even when the lifting posts are properly tilted around the wheels as fulcrums. For example, when the gutter lid is removed, the pair of holding members are attached to the end surface of the gutter lid. It can be hooked in order from the non-open groove side and easily held and removed, and when installing the gutter lid, it is easy to grab the gutter lid held by the pair of holding members while tilting the gutter lid. Can be installed in

Further, the removed gutter lid is moved by pushing and pulling the lifting post with the lifting post tilted and only the wheels are grounded.

It is easy to operate when moving.

According to the second aspect of the invention, in addition to the action described above, since the dimension between the pair of holding members of the holding mechanism can be adjusted, the gutter lids having different lengths can be adjusted. Also, the same gutter lid upper machine can be applied as it is to gutter lids having different length dimensions only by the above-mentioned interval adjusting work. Further, since the tension of the rope member stretched between the arm and the elevating post acts in the direction of reducing the arm, that is, in the direction of increasing the holding power of the gutter lid by the pair of holding members, The holding action of the gutter lid by the pair of holding members is further ensured.

According to the third aspect of the invention, in addition to the action described above, the holding mechanism is provided with the adjusting means capable of adjusting the distance between the holding member and the hooking claw in the extending direction of the holding member. Even for gutter lids having different thickness dimensions, it is possible to apply the same gutter lid upper machine as it is to gutter lids having different thickness dimensions only by the interval adjusting work using the adjusting means. It is a thing.

(B) According to the gutter lid lifting machine according to the first invention of the present application, a series of work of removal and installation including vertical movement of the gutter lid is continuously performed by a single gutter lid lifting machine. Therefore, as compared with the case where a dedicated device is used for each work and a preparatory work is required for each work as in the case where these works are performed separately using different devices, The device can be effectively used and work efficiency can be improved.

Further, since the vertical extraction work or the vertical embedding work of the gutter lid which cannot utilize the lever action is carried out by using the hydraulic jack which can obtain a large thrust, the worker can carry out only the convenient hydraulic jack operation. The gutter lid can be easily vertically extracted or vertically embedded by, for example, the labor burden on the worker is reduced as compared with the case where these operations are performed manually or using a manual jack. A single worker can also perform a series of removal and installation work including vertical extraction and vertical embedding, which can improve the work efficiency and reduce the work cost by labor saving. When a large pulling force is required due to sand that has been caught between the gutter and And it serves as a more pronounced had.

Furthermore, since the relative position between the lifting post and the pair of holding members is maintained regardless of the tilting operation of the lifting post, when the one side of the gutter lid is in the open groove state, the lifting post is lifted. It is possible to easily remove and install the gutter lid with the post tilted, which can improve workability as much as it is and always hold the gutter lid by the pair of holding members while moving. Is maintained satisfactorily and the gutter lid is not irregularly shaken, so that the operational safety during the movement of the gutter lid is enhanced.

(B) According to the gutter top device according to the second invention of the present application, in addition to the effect described in the above (a), in the case where the interval between the pair of holding members can be adjusted. The same gutter lid lifting machine can be applied as it is to the removal and installation work of various types of gutter lids with different length dimensions, improving its versatility and increasing the tension of the rope members between the pair of holding members. It is expected that the holding performance can be improved by causing the holding action to increase.

(C) According to the gutter top device according to the third invention of the present application, in addition to the effect described in the above (a), by the adjusting means, with the hooking claw in the extending direction of the holding member. By adjusting the interval, the same gutter lid upper machine can be applied as it is to the removal and installation work of various types of gutter lids with different thickness dimensions, so a dedicated attachment is required for each different size, for example. In comparison with such a case, it is expected that the versatility of the gutter top device is improved, and that the work cost can be reduced by effectively using the gutter top device.

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.

In order to clean the gutters 55, it is first necessary to vertically pull out only one specific gutter cover 50 vertically from the gutter cover row in which the gutter covers 50, 50, ... is there. In this case, as shown in FIG. 4, with the hydraulic jack 16 contracted, the gutter lid lifting machine Z
Is moved to the position of the specific gutter lid 50 to be removed, and the pair of holding members 35 and 36 are moved to the specific gutter lid 50.
Of the wheels 4 and 4 on the gutter lid 50 located next to the specific gutter lid 50, and the grounding legs 5 and 5 when the wheels are stowed. It is appropriately swung from the position to the side of the maximum swing position, and this is grounded to the lateral position 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, since the hooking claws 37, 38 of the holding members 35, 36 correspond to the work openings 52, 52, respectively, the movable parts such as the elevating post 10, the hold arm 30 and the like are moved. Since there is no support for the above, it descends by its own weight, and as shown in FIG.
Projects through the working openings 52, 52 to the lower side of the gutter lid 50 (finally, it can be lowered until the jack receiving portion 15 of the elevating post 10 contacts the rod 17 of the hydraulic jack 16). ).

Next, as shown in FIG. 6, the gutter lid lifting machine Z is moved forward as a whole to move the side surface 35 of the fixed holding member 35.
While c is brought into contact with one end surface of the gutter lid 50, the hold arm 30 is contracted so that the side surface of the movable holding member 36 comes into contact with the other end surface of the gutter lid 50, and in this state, the tension of the chain 14 is tightened. Adjust to regulate the extension of the hold arm 30. After that, the lifting post 10 is manually pulled up, or the lifting jack 10 is pulled up by extending the hydraulic jack 16 to pull up the hooks 37, 38.
Are engaged with the front end corner portion 50e and the rear end corner portion 50f of the gutter lid 50, respectively, and in this state, the adjusting bolt 41 is screwed to bring the contact plate 42 into contact with the upper surface 50c of the gutter lid 50.
Face close to.

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

Next, in this state, the hydraulic jack 16 is extended, or extension is restarted to extend it to the maximum extension position. Then, as shown in FIG.
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 from the lid receiving portion 56 of the gutter 55 upward. Taken out.

After that, as shown in FIG. 8, the lifting post 1
0 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 are brought into a grounded state, and this is moved to a predetermined position. Then, as shown in FIG. 9, the gutter lid 5 is placed separately and placed on the receiving members 58, 58.
With the position 0, the lifting 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 where the receiving member 58 on the front side is in contact with the portion of the side groove lid 50 close to the hook 37, the receiving force from the receiving member 58 is received. The hold arm 30 is pivotally displaced upward about the pivot shaft 33, and the fixed holding member 35 is moved.
The parallel state between the movable holding member 36 and
At the same time when the spaces 38 are opened, the chain 14 sags to release the extension restriction action on the hold arm 30 and the hold arm 30 extends to increase the distance between the fixed holding member 35 and the movable holding member 36. Will be done. As a result, the hooking states of the hooks 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 is automatically moved from the gutter lid upper machine Z side. It is detached and placed on the receiving members 58, 58.

As described above, when the gutter cover 50 is vertically pulled out, the gutter lid 50 is vertically pulled out by the thrust of the hydraulic jack 16. 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, as shown in FIG. 10, the second gutter lid 5 is removed.
Since there is a large space on the front side of 0, the second and subsequent gutter covers 50, 50, ... Can be removed by inclining them as in the conventional case. That is, as shown in FIG.
In the state where the hydraulic jack 16 is contracted, the gutter lid upper machine Z is rolled with the wheels 4, 4 while tilting backward and moved to the position of the second gutter lid 50. Of the latching claw 37 of the third opening and the gutter lid 50 for working
To face. 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 is gradually opened to the working opening 52.
While moving in, the movable holding member 36 gradually approaches the upper surface 50c of the gutter lid 50 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 holding arm 30 expands and the gap between the fixed holding member 35 and the movable holding member 36 increases, which causes the movable holding member 36 to end at the end of the gutter lid 50. Is entered from the upper side to the lower side of the gutter lid 50. After that,
When the lifting post 10 is raised vertically, the chain 1
4 is in a tensioned state, extension of the hold arm 30 is restricted, and the second gutter cover 50 is held by the fixed holding member 35 and the movable holding member 36 (that is, the state shown in FIG. 6). Becomes). 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 side groove 55 is completed, it is necessary to install the removed side groove lids 50, 50, ... Again on the side groove lid 50. In this case, the work procedure opposite to the above-described removal procedure is used. It can be performed in the same manner as the removal, and the description thereof is omitted here.

As described above, the gutter top device Z of this embodiment
In the above, all the work of removal / installation including vertical removal of the gutter lid 50, vertical embedding, and movement of the gutter lid 50 after removal can be continuously and labor-savingly performed by one gutter lid upper machine Z. The work efficiency is significantly improved compared to the conventional model.

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