DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter lid attaching / detaching apparatus (hereinafter referred to as "lid attaching / detaching apparatus"). More specifically, the present invention relates to a lid attaching / detaching apparatus which is easy to use and can easily, safely and efficiently attach / detach a gutter lid.

[0002]

2. Description of the Related Art A gutter (e.g., a gutter having a U-shaped cross section) is often provided on both sides of a road to allow rainwater or the like to escape to sewage or rivers. A gutter lid (hereinafter, referred to as a “lid”) F as shown in FIG. 15 is put on the gutter for the purpose of preventing a pedestrian from falling, securing a sidewalk on the gutter, and the like. There are many. When sand, soil, dust, dirt, sludge, etc. accumulate in such a gutter, it is necessary to clean the gutter. In this case, it is necessary to remove the lid F from the side groove and move the lid F onto a road or the like that does not interfere with cleaning (hereinafter, referred to as a “placement place”).

[0003] The removal of the lid F has conventionally been performed by an operator inserting his / her hands into the hand holding portions T ₁ and T ₂ provided at both ends of the lid F and lifting the lid F. In the case of such a manual operation, “bar” or the like is inserted into _{one of} the handle portions T ₁ and T ₂ , and this is used as a “lever” so that one of the handle portions of the lid F (for example, T _1). lift the edge etc.), part multiplied by the operator's hand (for example, have also been made to be easily inserted into T _1, etc.). However, this lid F has a certain bulk (for example, 600 mm × 600 m).
m × 100 mm) and weight (for example, about 35 kg), and it is often difficult to remove manually. Also, if a long time has passed since the gutter was installed,
The boundary between the cover F ₁ or the like and the adjacent lid F of interest, sand, earth or clogged, often removal is more, difficult.

[0004] In addition, one lid has a large number of lids F, F _1.
Etc. is generally Mounted in multiple-shape, the operator often be removed multiple cover F, and F ₁ and the like are continuously needed. An operator who continuously performs difficult manual operations as described above often suffers from low back. On the other hand, various devices and the like intended to facilitate this work have been proposed. For example, a “crab-clamp-type lid attaching / detaching device 91” shown in FIG. 16, a “lever-type lid attaching / detaching device 92, 93” as shown in FIGS. 17 and 18, and a “cart-shaped gutter” as shown in FIG. Lid carrier (Japanese Utility Model Publication No. 57-32055) 9
4 "has been proposed.

[0005]

However, the conventional apparatuses, such as the above-mentioned transporters 91 to 94, are not satisfactory in workability, usability, safety and the like for the following reasons. Therefore, it is often the case that it is not used and is stored in a warehouse or the like. That is, in the above device 91, as shown in FIG.
First, a pair of locking portions 911 and 912 are hooked on the hand-holding portions T ₁ and T ₂ of the lid F, and a pair of cross-shaped arm portions 9 are provided.
13 and 914, two workers located on the respective tip sides of the handle portions 915 attached to the respective arm portions 913 and 914,
916 is pushed down to hold the lid F firmly. Then, the lid F and the device 91 are lifted together,
After removing the lid F, the lid F is moved to a desired mounting position.

[0006] For this reason, the burden on the operator in the above-mentioned "pressing down the grip portions 915 and 916", "lifting the lid F and the device 91", and "moving to the mounting position" becomes large. Further, if the match is breath two workers performing depressing the grip portion 915 and 916, the lid F is one finger receiving portion (e.g., T _1, etc.) inclined side, it is difficult to disassemble. This is because the thickness of the cover F is about 10 cm, if inclined, its lid F is because being caught by the lid F ₁ next. Therefore, handling of this device 91
It is not so easy.

Further, as shown in FIG. 17, the device 92 includes a lever-shaped main body 921 and a grip portion 922 attached to the distal end side thereof. Then, first, this gripper 9
After the handle portions T ₁ and T ₂ of the lid F are scissors with the locking portions 922 a and 922 b at both ends of the 22, the lever-shaped main body 921 is pushed down and the lid F is lifted. Further, the lever-shaped main body 921
Is rotated in a predetermined direction, and the lid F is moved to a predetermined mounting position. Accordingly, even when the cover F is removed using the present apparatus 92, a heavy load is imposed on the operator as in the case of the above-described apparatus 91. In addition to this, it is considered that the operator often loses his or her balance at the time of “rotating the lever-shaped main body 921”. In particular, if the road is sloping, wheels 925
Is attached, there is a danger that the device 92 may roll down on the road by itself due to its own weight and the weight of the lid F, and use of the device 92 requires considerable care.

Further, as shown in FIG. 18, the device 93 has a lever-shaped main body 931 and a grip portion 932 which can be moved up and down by a predetermined hydraulic device 933. And
The predetermined handle 934 is moved up and down many times by a human hand, and the hydraulic device 933 is operated to lift the grip portion 932 and the lid F held by the grip portion 932. Therefore, it takes time and effort to operate the handle 934, and it is difficult to efficiently remove the cover F. Also, from the structural reason (stability etc.) of this device 93, the hydraulic device 9
In many cases, a sufficient stroke amount cannot be given to 33, so that the detaching operation is difficult or the handling tends to be troublesome. For example, if the stroke amount is insufficient, the lid F
Cannot be lifted by a sufficient amount. In addition, this device 93 also has the same drawbacks as the above-described device 92 because the movement of the lid F to the mounting position is performed while rotating the lever-shaped main body 931.

Further, the above-mentioned devices 92 and 93 are
Sand jammed boundary between adjacent F _1, when used to remove the lid F which is particularly difficult to come off due to the influence of mud, the lever-shaped body 921 and 931, it is necessary to particularly add a large force . At that time, the lid F suddenly comes off the gutter,
The grip portions 922 and 932 may come off the lid F suddenly. Then, the recoil may cause the lever-shaped main bodies 921 and 931 to jump upward and put the operator at risk.

As shown in FIG. 19, the transporter 94 includes a three-point support type carriage 941 having one rail 941a placed horizontally and a hoist 943 mounted on the rail 941a. Have. Then, the lid F is wound up and lifted by the hoist 943, and the hoist 943 is shown in FIGS. 19 and 21 (a).
944 and the like (restricted to ropes, chains, etc. that can be wrapped around the hoisting machine 943) 944, etc., as appropriate.

Therefore, this rope, chain 944, etc.
The unwinding and winding operations are troublesome, and there is a problem in working efficiency. If a heavy lid F is hung mainly from such a rope, a chain or the like 944, the bogie portion 941 is of a three-point support type and is inferior in stability. There is a possibility that the container 94 may fall over or the lid F that swings may collide with the operator. In fact, this transporter 9
In FIG. 4, a swing preventing member 945 as shown in FIG. 20 is provided to prevent the swing of the lid F, but it is difficult to firmly hold down the lid F by this member 945.

Further, in the transporter 94, the "movement of the lid F to the mounting position" is performed with the legs 941d and 941e on the rear side of the carriage 941 as a fulcrum, as shown in FIG. Do this while lifting the front side. Therefore, even during this movement, there is a possibility that the lid F swings greatly, the transporter 94 itself becomes unstable, and the swinging lid F collides with the operator. In this movement, the cart 941 is used like a lever, so that the above-mentioned devices 92 and 9 are used.
Similar to 3, the work burden, danger, etc. are large.

[0013] In addition, after completing the cleaning of the gutter, it is necessary to return the removed lid F, the F _1, etc. to its original location. However, either by hand, the device, regardless of whether using the transporter 92 to 94, a number of lid F that was removed from the gutter, a F _1, exactly revert back to the original position is not always easy. For this reason, the lids F, F returned to the gutters
For _each, resulting subtle positional deviation between the original position, by the accumulation lid F to be finally returned is not also less eliminated Hamama et al gutter. Than circumstances, such as the above, good ease of use, simple, safe, and efficient in the appearance of the desorption apparatus of the gutter for a lid that allows lid F, desorption work such as F ₁ has been desired.

The present invention has been made in view of the above point of view, is easy to use, and can easily remove and attach the gutter lid.

[0020]

The apparatus according to the first to fourth aspects of the present invention includes the support base constructed as described above, the translation means, the elevating means, the gripping means, and the driving means. The support is excellent in stability because the fixed frame portion of the square ring-shaped frame structure is supported at four points by each support leg portion. Further, the gripping means includes a body portion, and hook portions disposed on both sides of the body portion. Each of these hooks includes an arm plate that hangs down from each end of the body, and a rake plate that projects substantially horizontally from the lower end of each arm plate toward the other arm plate. ing. In addition, each hook portion can be appropriately approached and separated.

Therefore, a desired lid can be firmly gripped by each hook portion. That is, first, the interval between the hook portions is slightly wider than the interval between the hook portions of the lid, and each rake plate portion is inserted from above the lid to the lower surface side of the lid. Then, if the distance between the hooks is reduced to the distance between the handle portions of the lid, each rake plate portion scoops the bottom portion on the side of each handle portion of the lid,
In addition, each arm plate portion is in close contact with the side portion of the lid on the side of each handle portion, so that the lid can be firmly gripped.

The elevating means includes a movable frame portion, an elevating rod-shaped portion, and each connecting portion. Among these, the movable frame portion is arranged so as to be able to move up and down in the fixed frame portion. Further, since the lifting rod supports the movable frame from below, and each connecting part connects the lower side of the movable frame and the gripping means, if the lifting rod is moved up and down, the movable frame is moved. The part and the gripping means move up and down integrally. In this way, it is the movable frame part having a frame shape and having sufficient rigidity to move the gripping means up and down, and moving the movable frame part up and down moves the movable frame part firmly from below. It is a lifting rod part that supports. Therefore, even if the gripping means grips the heavy lid, the lid, the gripping means and the elevating means do not swing greatly.

The track on which the movable frame moves up and down is set in a certain direction along the axis of the lifting rod by the action of the bearing. As a result, when removing the lid, the gripping means can be raised almost straight. For this reason, sand, mud, etc. are clogged at the boundary between the lid to be removed and the adjacent lid, and even in a situation where the removal of the lid is difficult, the lid from each of the hooks can be used as a target.
A well balanced force is applied and such a lid can be easily removed. Further, the gripping means is connected via each connecting portion. Therefore, the gripping means is suspended with some play in the movable frame portion, and it is easy to align the gripping means with the target lid.

Further, the translation means has movable support portions which can move in the front-rear direction on the vertical frame members, and movable abutments provided between the movable support portions. A bearing for pivotally supporting the elevating rod in such a manner that it can be moved up and down is attached to the movable abutment. Therefore, the lid gripped by the gripping means and lifted by the elevating means can be easily translated outside the side groove by the translation means. For example, when the front side of the support stand straddles the side groove and the rear side is located on the road, the removed lid can be conveyed toward the road by the translation means. That is, if the location of the road located on the rear side of the support table is set as the mounting location, the movement to the mounting location can be performed without moving the apparatus. For this reason, it is not necessary to move the device, the transporter, and the like to the mounting position together with the lid, unlike the conventional device, the transporter, and the like. As a result, the work efficiency of the attachment / detachment operation of the lid is improved, and it is possible to prevent the worker from being hurt or danger during this operation.

The driving means includes an operating handle, a transmission shaft, and a driving force conversion transmission unit. The operation handle is disposed outside the fixed frame portion, and the transmission shaft is bridged between the operation handle and the translation means. Then, the translational driving force in the front-rear direction applied to the operation handle is transmitted to the translation means via the transmission shaft. Further, the rotational driving force applied to the operating handle is transmitted to the driving force conversion transmitting unit through the transmitting shaft. Then, the rotational driving force is transmitted to the lifting rod portion by the driving force conversion transmitting section. Therefore, the operator operates the operation handle from outside the fixed frame portion,
The lid can be attached and detached. For this reason, a desorption work can be performed safely.

According to the fifth aspect of the present invention, the operating handle is arranged outside the rear side of the fixed frame portion, and a translation driving force is applied by moving the operating handle back and forth along the axial direction of the transmission shaft portion. ing. Therefore, the operator can operate the device from the rear side. In the sixth aspect of the present invention, the second translation unit similar to the translation unit is disposed forward of the translation unit, and the second elevation unit similar to the elevation unit and the second translation unit similar to the gripping unit. Holding means. In addition, a second operation handle similar to the operation handle is provided on the outside of the front side of the fixed frame portion, and the second operation handle and the second translation unit are hung between the second operation handle and the second translation unit. Second
A second transmission shaft portion capable of transmitting a second translational driving force in the front-rear direction to which the operating handle is applied to the second translational moving means; and a second transmission shaft transmitting a second rotational driving force applied to the second operating handle. And a second driving force conversion transmitting unit that receives the second rotating driving force into a second lifting driving force and transmits the second rotating driving force to the second lifting rod. That is, two units each including the translation means, the elevating means, and the driving means are provided.

The present apparatus is mainly used by arranging the front-rear direction along the longitudinal direction of the side groove. Then, a plurality of lids are attached and detached while the apparatus is fixed. As a result, the following operation is achieved. That is, cleaning of the inside of the side groove after the lid is removed may be performed manually, but efficiency can be improved by using a vacuum car or the like for cleaning. However, a suction hose such as a vacuum car is thick and has a certain degree of rigidity.
It is often difficult to insert into the side groove from which only the lid is removed. Therefore, in the first to fourth aspects of the present invention, it is generally considered that the plurality of lids are removed while appropriately moving the device, and an opening through which the hose can be inserted is formed on the side groove. On the other hand, according to the present apparatus, there is a great significance in that a plurality of lids can be removed without moving the apparatus.

In the seventh invention, the operating handle is disposed outside the fixed frame in either the left or right direction, and the translation driving force is applied to the operating handle so as to be substantially perpendicular to the axial direction of the transmission shaft. It is moved along the direction to be added. Therefore, the operator can operate the device from the side. For this reason, it is effective for the work of attaching and detaching the lid covered by the gutter provided on both sides of the narrow road or the gutter of the road with heavy traffic.
