Description

Description: TECHNICAL FIELD The present invention relates to a carrier used for carrying drums, fume tubes, cylindrical rugs, and other cylindrical objects.

(Prior Art) Conventionally, a cylindrical object such as an earthen pipe in sewage works has been moved by an operator rotating the ground with his / her hips.

Also, when winding and transporting unnecessary rain mats in buildings and hotels, both ends are lifted by two people and transported as they are, or transported on a trolley or the like. .

In such a case, in recent years when labor is short, it is necessary to secure workers by facilitating the work, and in many cases, the elderly are hired. Needed a simple carrier.

(Problems to be Solved by the Invention) In recent years when labor costs are soaring, if it becomes possible to transport heavy objects such as carpets easily by a single worker instead of the conventional work performed by a plurality of workers. This will reduce costs and allow the surplus one to engage in other tasks at the same time.

It is another object of the present invention to provide a safe carrying device that can be easily carried out by an elderly person without requiring strong muscular strength for carrying work.

(Means for Solving the Problems) Tip portions are provided on both sides of the front end portion of the bogie 2 having the front wheel 3a and the rear wheel 3b.
5a is provided with two arms 5 projecting in parallel to the left and right at an angle に 対 し て upward with respect to the floor surface, and each of these two arms has a support shaft 6a at the tip end thereof with a constant inclination angle θ with respect to the floor surface. It has a pair of guide rollers 6 rotatably supported by support shafts 6a mounted opposite to each other, and has a handle 4 for operation at the rear of the carriage 2,
Further, a V-shaped notch 7 is formed in the front part of the bogie 2, the bogie 2 is advanced toward the end face of the cylindrical object 8, and is pushed forward by being tilted forward with the handle 4, along the peripheral side surface of the cylindrical object. Thus, the pair of guide rollers 6 are moved forward and mounted on the carriage 2 from the front end of the carriage 2.

An L-shaped member 9 having an intermediate portion pivotally supported at the rear portion of the four-handle handle 2 and an auxiliary wheel 10 attached to a lower end of the L-shaped member 9 are provided.

Further, a winch 11 is mounted on the carriage 2 in front of the handle 4 so that the cylindrical object can be attracted via the wire 12.

(Example) It demonstrates based on a figure. In FIG. 5, reference numeral 1 denotes a carrier for a cylindrical object according to the present invention (hereinafter simply referred to as a carrier). The carrier 1 is provided with a truck 2 having wheels 3 (two front wheels 3a and two rear wheels 3b), and is provided at a front end of the truck 2 so as to protrude in parallel in plan view.
It comprises a pair of arms 5 and a guide roller 6 attached to the tips of these arms 5.

An operation handle 4 is attached to the carriage 2 at a rear portion facing the attachment side of the guide roller 6. After pushing the handle 4 to move the cart 2 forward, the cart 2 is tilted forward by pulling up the handle 4, and toward the bottom side of the tubular object 8,
The pair of arms 5 can easily enter (the seventh arm).
Figure).

The pair of arms 5 are provided in parallel with the front end of the bogie 2 in plan view, and the tip 5a thereof has an angle ψ with respect to a horizontal plane (floor surface) as viewed from the side as shown in FIGS. Have.

Further, as shown in FIG. 3, a guide roller 6 provided on a pair of parallel arms 5 provided at the front end of the bogie 2 has a support shaft 6a whose horizontal axis (floor surface) and a constant inclination angle θ ( For example 45
Ii) The left and right guide rollers 6 are mounted facing each other inward. It is convenient if the inclination angle θ of the guide roller 6 can be changed so as to correspond to cylindrical objects having different curvatures.

Further, the shape of the guide roller 6 may be a cylindrical shape as shown in FIG. 1 or a spherical shape (not shown), or a two-wheel roller as shown in FIG.

As shown in FIGS. 1 and 2, a V-shaped notch 7 is provided at the front end of the carriage 2, and the V-shaped apex is located near the front wheel 3a attached to the front of the carriage 2. . Due to the presence of the V-shaped notch 7, when the cylindrical object 8 enters the trolley 2, the front part of the trolley 2 smoothly rides on the trolley 2 without interfering with the lower end surface of the cylindrical object 8. it can. The notch is not limited to the V-shaped notch 7 but may be formed in a shape that does not interfere with the end face of the cylindrical object 8, for example, a U-shape.

(Operation) In order to carry the cylindrical object 8 by the carrier 1 with the above-described configuration, the bogie 2 is pushed forward by the operating handle 4, and the handle 4 is slightly lifted upward to thereby cause the front wheel to move. The two parallel arms 5 are inserted into the lower side of the cylindrical object 8 while tilting the cart 2 forward with the fulcrum 3a. Further, the handle 4 is pushed forward and kept pressed until the left and right guide rollers 6 contact the lower peripheral surface of the cylindrical object 8.
When the guide roller 6 comes into contact with the cylindrical object 8, the carriage 2 is returned to a horizontal position by pulling down the handle 4. Then, the front end of the cylindrical object 8 is lifted up by leverage with the front wheel 3a as a fulcrum and the guide roller 6 as a point of action. In this case, due to the principle of leverage, the handle 4 can be pulled down with a force much smaller than the actual weight of the cylindrical object 8, and the end of the cylindrical object 8 is easily lifted. When the end of the cylindrical object 8 is lifted, the bogie 2 is further advanced by the handle 4, and the side surface of the cylindrical object 8 and the guide roller 6 are easily rolled by the rolling contact with the small frictional resistance. It can be mounted on the cart 2.

As means for tilting the carriage 2 forward, as shown in FIG. 8, a handle 4 'comprising an L-shaped member 9 also serving as a handle and an auxiliary wheel 10 can be considered. The L-shaped member 9 of the handle 4 ′ is mounted on the rear wheel of the carriage 2. By tilting the L-shaped member 9 forward as indicated by the arrow a, the auxiliary wheel 10 is pressed against the floor surface, the rear end of the carriage 2 is lifted, and at the same time, the carriage 2 leans forward.

As means for tilting the carriage 2 forward, a hydraulic cylinder (not shown) may be further attached to the rear end of the carriage 2 to move the carriage 2 up and down.

In addition, by using two carriers 1 as a set, one is fitted to one end of the cylindrical object 8 and the other is fitted to the other end, so that the long cylindrical object 8 is carried or parallel at the place. Movement, turning, and the like can be performed. Specific examples of such a long cylindrical object 8 include wood, telephone pole,
Pipes and the like are conceivable.

Although not shown, fixing a carrier for cylindrical objects to a fork of a forklift is effective for carrying heavy cylindrical objects. Specific examples of such a cylindrical object include a paper roll, a coil electric wire, and a thin steel coil.

Furthermore, although not shown, by fixing the carrier of the cylindrical object to the rear end of the bed of the bed inclined type truck,
This is effective for transportation when the cylindrical object is large and heavy. In this case, the effect of the cylindrical object carrier can be obtained by moving the cylindrical object to the vehicle side by winding the wire attached to the cylindrical object by the winch attached to the truck while the truck is stationary. In combination, the cylindrical object can be easily mounted on a truck.

FIG. 9 shows a state in which a manual winch 11 is mounted on the trolley 2. By this operation, a cylindrical object can be easily mounted via the wire 12.

(Effect) With the above-described configuration, the conventional method requires two workers to transport a rug such as a carpet by winding it into a cylindrical shape. It can be carried out.

In addition, since the lifting is performed by applying the lever action, a strong muscle force is not required, and even if the worker is an elderly person, it can be easily transported.

Further, since the inclination angle θ of the guide roller 6 with respect to the floor surface can be changed, it is not completely cylindrical, such as a rug wrapped in a cylindrical shape, and can cope with an object having an unstable shape. It can be mounted on top.

In addition, by using the present invention in combination with two, it is easy to transport long objects, and by using in combination with a forklift or a truck for transporting vehicles, a heavy cylindrical object can be easily mounted. Is possible, and its utility is incalculable.
