Description

[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention relates to a snow removal device for a gable roof, and more particularly to a device for scraping off snow by a scraper traveling along the upper surface of the roof. .

(Prior Art) Conventionally, as a device for removing snow from a roof, as described in, for example, Japanese Utility Model Laid-Open No. 60-22621, a device for melting snow on the roof by heat and sliding it down, or
For example, as described in Japanese Utility Model Publication No. 57-38486 and Japanese Utility Model Publication No. 58-5777, there are known endless sheets that cover the upper surface of the roof and devices that remove snow by circulating or sliding a shutter. .

However, these devices generally have problems of large scale and high fuel consumption.

Therefore, as described in Japanese Utility Model Laid-Open No. 62-19313, as a roof snow removal device that has a simple structure and is easy to install and can be driven with a small power, it is laid down on the roof by a circulating scraper. A device was proposed that repeatedly sweeps down the falling snow under the eaves. In this device, for example, a chain is hung between a pair of sprockets driven by a motor supported on the roof eaves and a pair of sprockets supported on the roof eaves, and a scraper is installed between these chains. It has a structure.

By the way, when installing this scraper type snow removal device on the gable roof, the devices will be installed independently on each side of the ridge, and the snow on each side of the ridge will be wiped by separate scrapers. It will be taken out and removed from each of the two eaves. The same applies to the above-described conventional snow melting type snow removing device and seat or shutter type snow removing device. However, if one of the eaves of the gable roof faces the road, you may not want snow to fall from this eaves. Also, when snow is removed from both eaves, it is troublesome to dispose of the removed snow. Furthermore, it is not economical to install snow removal devices separately on each side of the roof.

(Problems to be solved by the invention) As described above, in the conventional roof snow removal device including the scraper type, in the case of the gable roof, snow is removed from both eaves. If the eaves of the eaves face the road, it is not preferable to drop the snow from the eaves, and if the snow is removed from both the eaves, disposal of the removed snow is troublesome, so improvement was desired. .

The present invention is intended to solve such a problem,
An object of the present invention is to provide a snow removal device that can remove snow accumulated on both sides of a gable roof ridge from only one eave tip.

[Constitution of device]

(Means for Solving the Problems) In the snow removal device for a gable roof of the present invention, in order to achieve the above object, a plurality of one-sided eaves sprockets are supported above one eave of the gable roof, A plurality of other side eaves sprockets corresponding to the one side eaves sprockets are supported above the other eaves portion, and a plurality of lower eaves sprockets corresponding to the one side eaves sprockets are provided above the ridge. While supporting the side ridge sprocket, each of the lower ridge sprocket is positioned above each of the lower ridge sprocket to support a plurality of upper ridge sprocket, a plurality of endless chains corresponding to the one side eave sprocket and the other side eave And the chain on the lower ridge sprocket and the upper ridge sprocket corresponding to the eaves sprocket. I am going to turn along the inclination direction of this roof above. And
A scraper is installed between the plurality of chains so that the scraper, which is located in the lower part of the chains, advances with its lower edge close to the upper surface of the roof. Further, a drive source for driving the plurality of chains to rotate at the same speed via a sprocket, for example, the one side eaves sprocket is provided. Furthermore, rails are fixedly supported on the gabled roof in parallel with the lower and upper portions of each chain, and a V-pulley and the like that rolls on the rails is engaged with the rails. The wheel is rotatably supported by the scraper.

(Operation) In the snow removal device for the gable roof of the present invention, a plurality of endless chains are driven at the same speed from one side eaves sprocket to, for example, a lower side sprocket and another side eaves by driving a drive source through the sprockets. Pass through the upper sprocket and upper sprocket, and go again to the one-side eaves sprocket. That is, the chain runs on the gable roof along the slope direction of the roof. Then, the scraper installed between the chains and located at the lower part of these chains advances from the one-side eaves sprocket to the lower ridge sprocket with the lower edge close to the upper surface of the roof. , Sweeping snow falling on the surface of the gable roof on the side of the sprocket on one side of the ridge is swept up to the ridge. Then, the scraper goes over the lower sprocket,
After the traveling direction is changed along the angle formed by the ridge, it advances to the other side eaves sprocket, and the snow swept on the one side eaves side sprocket side and the other side eaves side sprocket side from the ridge Sweeping snow falling on the other side eaves to the eaves on the side of the sprocket, and let it fall from this eave. After that, the direction of travel of the scraper is reversed over the other side eaves sprocket, and the scraper returns from the roof top side sprocket to the one side eaves sprocket without sweeping snow away from the upper surface of the roof. As the scraper circulates in this manner, the wheels supported by the scraper roll on rails that are parallel to the lower and upper parts of each chain, respectively. As a result, the weight of the scraper is firmly supported, and the scraper and the chain are positionally regulated in a direction other than the traveling direction by the concavo-convex engagement between the wheel body and the rail. Thus, the scrapers that are pulled and run by the chains repeatedly remove snow falling on both sides of the gable roof from only one of the eaves.

Reference numeral 19 has a curved portion 120 on the tip side. Then, a plurality of snow sweep fins 121 are attached to the scraper shafts 73 via the attachments 119 so that the magnet ring 112 is located therebetween. In addition, this fin 1
When attaching 21, the curved portions 120 of the fixture 119 are hooked in the plurality of engagement holes 122 formed in the fin 121, a small amount of adhesive is applied, and the curved portions 120 are tightened. The snow sweep fin 121 is made of, for example, a 250 μm-thick polyester thin film, and when located in the lower portion of the roller chain 71, the lower edge of the roof tile 8 has the roof 2.
It slides on top. Further, the upper and lower edge portions of the snow sweep fin 121 are bent portions 123 that are slightly bent in the traveling direction.

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

The motor 33 is driven during snowfall, and the driving force of the motor 33 is transmitted to the drive shaft 24 via the speed reducer 34, the transmission sprocket 36, the electric chain 37 and the transmission sprocket 31, and together with the shaft 24, a pair of drive sprockets. twenty five
Rotate at the same speed. This allows a pair of roller chains
71 travels from the drive sprocket 25 at the same speed to the drive sprocket 25 again on the lower ridge sprocket 50, the reverse sprocket 45 and the upper ridge sprocket 56.
That is, particularly as shown in FIG. 2, the roller chain 71
On the gable roof 2, the scraper 72 moves along the direction of its inclination, and the scraper 72 interlocking with these roller chains 71 via an attachment 95 advances. Along with that, the V pulley 93 of the sprocket 72 located in the lower part of the chain 71 rolls on the lower rail 63, and the V pulley 93 of the scraper 72 located in the upper part of the chain 71 rolls to the upper rail 64. Roll over,
As a result, the weight of the scraper 72 is supported by the rails 63 and 64 at both ends thereof via the V pulley 93. In addition,
The operation direction of each member is indicated by an arrow in each drawing. The thick arrow finger is the direction of travel of the scraper 72.

Then, the snow sweep fins 121 of the scraper 72 located in the lower part of the roller chain 71 are first moved from the drive sprocket 25 to the lower ridge sprocket 50 with the lower edge being close to the inclined surfaces 6 and 7 of the roof 2. Then, the snow falling on the front slope 6 of the gable roof 2 is swept up from the front eave 4 at the lower edge to the ridge 3. Next, the scraper 72's snow-sweep fins 12
1 is a reverse sprocket after the traveling direction is changed along the angle formed by the ridge 3 part beyond the lower sprocket 50
Proceeding to 45, the snow that has fallen on the back slope 7 along with the snow swept on the front slope 6 is swept down to the back eaves 5, discharged from the eaves at the lower edge, and dropped.

In this way, when the scraper 72 advances from the front side eaves 4 to the back side eaves 5, the magnet ring 112 supported by the scraper shaft 73 to which the snow sweep fins 121 are attached is magnetically attached to the roof tile bar 8 and the roof tile bar 8 is attached. By rolling on
Scraper shaft 73 and snow sweep fins due to snow resistance
The lifting of 121 is surely prevented. Moreover, since the snow removal piece 116 immediately in front of the magnet ring 112 removes snow on the passage of the ring 112, it is possible to prevent the magnetic force from being reduced due to the presence of snow.

In addition, at both ends of the scraper 72, the floating stopper rollers 102 contact the rail 63 from below, so that the scraper 72 is prevented from rising. Along with this, since the bent portion 88 of the metal fitting 81 fixed to the end surface of the scraper shaft 73 and having the levitation stop roller 102 axially attached is screwed to the peripheral surface of the pulley stopper metal 85, Rotation is prevented.

In addition, bent portions 123 at the upper and lower edges of the snow sweep fins 121
Ensures snow sweeping and snow removal.

Such a scraper 72 pulls the chain 71 to sweep snow in the downward direction of the slope, in the upward direction of the slope, or in the horizontal direction. Therefore, the snow on the entire surface of the gable roof 2 is surely swept out.

Further, the scraper 72 is pulled by the chain 71 to reverse the traveling direction beyond the reversing sprocket 45, and then the left and right ends are supported by the rails 64 via the V pulleys 93 while passing through the air and the upper ridge sprocket. Cross over 56 and return to drive sprocket 25. At this time, the chain 71 is supported by the rails 64, so that the weight of the scraper 72 does not cause the chain 71 to hang down. Further, since the position of the chain 71 is regulated by the engagement between the rail 64 and the V pulley 93, the chain is not removed. Since the scraper 72 which is returning is located above the roof 2, it does not sweep snow.

In this way, the circulating scraper 72 repeatedly removes the snow falling on both sides 6, 7 of the gable roof 2 only from the eaves on the back side of one side.

Therefore, no problem occurs even if the front side eaves 4 faces the road. In addition, it is easy to dispose of the snow dropped from the roof 2.

In addition, since light and soft snow falling on the roof 2 is repeatedly eliminated little by little, the power required for driving the scraper 72 is small, the operating cost is low, and the snow falling from the eaves is the least, which causes an accident. There is no danger of occurrence.

Furthermore, both sides of the gable roof 2 by the same scraper 72
Since 6 and 7 snows can be eliminated, the structure of the snow removing device can be simplified as a whole as compared with the case where the snow removing device is independently installed on each surface 6 and 7, and there is no waste and the cost can be reduced.

In addition, it is advantageous to use a polyester thin film as a material for the snow sweep fins 121 of the scraper 72 in addition to being advantageous in terms of water resistance, elasticity, etc.

By the way, since the snow sweep fins 121 slide on the roof tiles 8,
Only the snow accumulated above the height of the roof tiles 8 is removed, and snow remains between the roof tiles 8. However, since the remaining snow is small, there is no problem. Rather, the fact that the snow sweep fin 121 slides on the roof tile 8 has the advantage that the shape of the snow sweep fin 121 can be simplified.

In addition, sprocket 2 for hanging the roller chain 71
Since 5,45,50,56 and rails 63,64, etc. are unitized by the mounting base materials 11,12, the construction of the device on the roof 2 is easy. With this, sprockets 25,45,50,5
It is also possible to attach 6 or the like to any position of the roof 2, for example, to the left and right side edges. Further, the distance between both roller chains 71 can be surely made constant, and the chains 63 can be rotated around the rails 63 and 64, so that the chain 71 can be prevented from hanging down and the chain can be reliably removed.

By the way, since the V pulley shaft 80 and the pulley stopper 85 are slidable in the axial direction with respect to the scraper shaft 73 and the metal fitting 81, the V pulley shaft 80 side slides with respect to the scraper shaft 73 side during construction. Thus, the positions of the respective members are automatically adapted to the error dimensions associated with the mounting work of the rails 63, 64 and the mounting base materials 11, 12. As a result, the occurrence of a failure such as derailment of the V-pulley 93 or disconnection of the chain 71 is more reliably prevented, and extremely smooth operation is performed.

Although the number of scrapers 72 is three in the above embodiment,
The number of scrapers 72 may be appropriately set according to the size of the roof 2 and the like. For example, if the sweeping speed of the scraper 72 is set to 8 to 18 m / min., A plurality of scrapers 72 can be attached according to the length of the roller chain 71 so that one point on the roof 2 can be swept at intervals of 60 seconds or less. Good.

If the width of the roof 2 in the left-right direction is large, the number of the drive sprockets 25 and the roller chains 71 may be three or more.

The motor 33 may be controlled by a snowfall sensor so that the motor 33 is automatically driven during snowfall.

Further, the present snow removing device can be applied not only to the roof 2 with tile roofs but also with a roof without roof tiles. Also, if lightweight steel is used for the passage of the magnet ring 112, it can also be used for roof tiles. Applicable.

[Effect of device]

According to the present invention, a plurality of one side eaves sprocket and another side eaves sprocket respectively supported on both eaves of the gable roof, and a plurality of lower ridge sprocket and upper side ridges supported on the ridge in a staggered manner. A number of chains with scrapers are laid over the ridge sprocket, and the wheels mounted on the scraper roll on the gable roof in parallel with the rails supported in parallel with the chains. As a result, it is possible to repeatedly eliminate snow falling on both sides of the gable roof ridge from only one eave side, and therefore, even if the eave on the opposite side faces the road etc., no problem will occur, Disposal of snow removed from the roof will also be easier. Moreover, since snow can be swept on both sides of the gable roof with the same scraper, the configuration of the entire snow removing device can be simplified and the cost can be reduced.
