Description

The present invention is a trolley widely used as a means for transporting materials during construction inside underground buried pipes such as sewer pipes, electric power pipes, water pipes, and agricultural water pipes, or as a means of transportation for various investigations within the pipes. Regarding.

When rehabilitating buried pipes such as aging sewer pipes, for example, various materials are often transported to the site in the sewer pipes, but conventionally, human-powered trolleys have been used for these transportation operations. ing.

On the other hand, a "pipeline self-propelled vehicle" that is not for material transportation but can move inside the pipeline has been proposed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2012-201260

In the material transportation work performed inside the sewer pipe, a trolley loaded with materials with a total weight of about 100 kg is often manually moved over 100 m to 200 m in the sewer pipe. Since sewage may flow in the pipe, it puts a heavy burden on the workers.

On the other hand, the "pipeline self-propelled vehicle" described in Patent Document 1 is equipped with an electric motor and has a function of traveling on its own inside the pipeline, but has a function of loading a material of about 100 kg. Absent.

Therefore, an object to be solved by the present invention is to provide a trolley capable of facilitating the material transportation work in the sewer pipe and reducing the burden on the operator.

The trolley according to the present invention is a trolley capable of traveling inside a tubular body along the longitudinal direction of the tubular body.
A loading portion on which materials can be loaded, a plurality of wheels provided on the previously described loading portion to allow the previously described loading portion to travel along the longitudinal direction of the tubular body, an electric motor for driving the wheels, and the electric motor are operated. With batteries,
A folding mechanism is provided in the load section described above.
The wheel is characterized in that its rotation axis is in contact with the inner peripheral surface of the tubular body in a state of being orthogonal to the radial direction of the tubular body.

It is desirable that the bogie is provided with an operation unit that starts, stops, and changes the direction of the bogie.

In the carriage, it is desirable that the wheels, the electric motor, and the battery have a waterproof function.

Wherein in the carriage, the loading unit, and a folding mechanism provided.

In the trolley, it is desirable that the folding mechanism is a hinge that foldably joins the plurality of frame bodies constituting the load portion described above and the frame bodies.

According to the present invention, it is possible to provide a trolley capable of facilitating the material transportation work in the sewer pipe and reducing the burden on the operator.

It is a partially omitted plan view which shows the dolly which is an embodiment of this invention. It is a partially omitted side view of the bogie seen from the direction of arrow A in FIG. It is a partially omitted rear view of the bogie seen from the arrow line B direction in FIG.

Hereinafter, the carriage 100 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3.

As shown in FIGS. 1 to 3, the trolley 100 according to the present embodiment is capable of traveling inside a cylindrical sewer pipe 30 which is a kind of tubular body along the longitudinal direction of the sewer pipe 30, and is a material. A loading unit 10 capable of loading 25, a plurality of wheels W provided diagonally downward on the left and right side surfaces of the loading unit 10 for traveling the loading unit 10 along the longitudinal direction of the sewer pipe 30, and each wheel W. It includes electric motors 15, 16, 17, 18 for driving, and storage batteries 21, 22, for operating electric motors 15, 16, 17, 18. Each of the plurality of wheels W is in contact with the inner peripheral surface 32 of the sewer pipe 30 with its rotation axis C2 orthogonal to the radius 31 direction of the sewer pipe 30. The reference numeral C1 in FIG. 3 indicates the central axis of the sewer pipe 30.

As shown in FIGS. 1 and 3, connecting portions 11, 12, 13, and 14 projecting diagonally downward from the left and right side surfaces are provided in front of and behind the left and right side surfaces of the loading portion 10, and these are connected. Electric motors 15, 16, 17, 18 and a pair of front and rear wheels W are attached to portions 11, 12, 13, and 14, respectively. As shown in FIG. 3, fence-shaped members 24 are erected on the upper surface of the loading portion 10 near the left and right side surfaces to prevent the material 25 from collapsing.

As shown in FIG. 1, the carriage 100 includes an operation unit 40 that starts, stops, and changes the direction of the carriage 100. The operation unit 40 is connected to the control unit 23 attached to the lower surface of the loading unit 10 by a cable 46. The operation unit 40 is provided with an ON button 41, an OFF button 42, a right turn button 43, a left turn button 44, and an emergency stop button 45.

In the carriage 100, the wheels W, the electric motors 15, 16, 17, 18, the storage batteries 21 and 22, and the control unit 23 have a waterproof function. The storage batteries 21 and 22 are detachably mounted on the loading unit 10. Further, various wirings and cables between the electric motors 15, 16, 17, 18, the storage batteries 21, 22, the control unit 23, and the operation unit 40 are all connected by waterproof connectors.

As shown in FIGS. 1 and 3, in the trolley 100, the loading portion 10 folds the right frame body 10R and the left frame body 10L having a rectangular plan view shape, and the right frame body 10R and the left frame body 10L. It has a plurality of hinges 19 and 19 to be joined as possible. The right frame body 10R and the left frame body 10L are formed by joining square tubular members 1 and 2 having different lengths in a ladder shape.

As shown in FIG. 3, since the right frame body 10R and the left frame body 10L can be folded in the arrow V direction around the hinge 19, they can be carried from the ground into the sewer pipe 30 via the manhole. ..

If the trolley 100 is carried into the sewer pipe 30, the material 25 is loaded on the loading unit 10, and the operator operates the ON button, the right turn button 43, the left turn button 44, etc. of the operation unit 40, the trolley 100 becomes The material 25 can be transported to the destination by traveling in the sewer pipe 30 along the longitudinal direction thereof. Therefore, the material transportation work in the sewer pipe 30 can be facilitated and the burden on the operator can be reduced.

Further, when the carriage 100 travels in the sewer pipe 30, all of the plurality of wheels W are placed on the inner peripheral surface 32 of the sewer pipe 30 in a state where their respective rotation axes C2 are orthogonal to the direction of the radius 31 of the sewer pipe 30. Since it is on the ground, it can run while maintaining a stable posture. The carriage 100 is not limited to the inside of the cylindrical sewer pipe 30, and can travel even on a flat surface such as the bottom surface in a box culvert.

The trolley 100 described with reference to FIGS. 1 to 3 shows an example of the trolley according to the present invention, and the trolley according to the present invention is not limited to the trolley 100 described above. Further, the use of the carriage 100 is not limited to the above-mentioned transport work.
