Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carrier truck for carrying a large load such as a house unit for traveling, and particularly to a carrier truck for a narrow space capable of carrying a large load on a narrow road where a truck or the like cannot enter.

[0002]

[Prior art]

 A truck or the like is generally used as a vehicle for carrying a large load. Further, there is known a carrier truck including left and right crawler type traveling bodies and a luggage carrier.

[0003]

[Problems to be solved by the device]

 Trucks cannot drive on narrow roads, and in the case of a carrier truck that has a track-type traveling body, the size of cargo that can be carried is determined by the size of the cargo bed, and the size of a road that can be driven empty is the cargo bed. Since it is determined by the size of, it will not be possible to drive empty cargo on narrow roads if large luggage can be carried.

Therefore, an object of the present invention is to provide a carrier truck capable of solving the above-mentioned problems.

[0005]

[Means for Solving the Problems]

 A main frame 7 is mounted between the left and right crawler-type traveling bodies 6 and 6, and a drive and control device such as an engine is mounted on the main frame 7. The front movable frame 20 and the rear movable frame 22 along the pair of left and right receiving frames 16 so as to freely slide in the front-rear direction. A carrier truck provided with a support arm 25 that is rotatable in the horizontal direction.

[0006]

[Operation] Since luggage can be placed and run across the support frames 25 located in front of and behind the crawler-type traveling body 6, it is possible to transport a luggage of approximately the same size as the plane size of the trolley, and the front portion. By sliding the rear movable frames 20 and 22 and rotating the support arm 25, the overall plane size can be reduced or increased. Therefore, the plane size of the trolley can be adjusted according to the size of luggage to be transported. It can be adjusted by adjusting the size of the trolley, and when it is self-propelled with an empty load, it can run in a narrow area with the plane size of the trolley being minimized.

【Example】

 As shown in FIGS. 1, 2, and 3, a track frame 1 is provided with a sprocket 2, an idler 3, and a rolling wheel 4, and a crawler belt 5 is wound around the sprocket 2, the idler 3, and the rolling wheel 4 to perform crawler type traveling. A body 6 is provided, and a main frame 7 is attached between the track frames 1 of the left and right crawler type traveling bodies 6 to form a device storage portion 8 between the left and right crawler type traveling bodies 6, 6.

An engine 9, a hydraulic pump 10, an operation valve 11, an electromagnetic proportional valve 12, a fuel tank 13, a hydraulic oil tank 14, a hydraulic oil cooler 15, a control device (not shown), and the like are attached to the equipment storage portion 8. Each device is not in contact with the ground and does not project higher than the crawler-type traveling body 6 above.

A pair of left and right hollow receiving frames 16 are attached to the upper left and right sides of the main frame 7 in parallel with each other in the front-rear direction. Inside each of the receiving frames 16, a pair of left and right front slides are installed. A frame 17 and a rear slide frame 18 are slidably inserted in the front-rear direction, respectively, and a front horizontal frame 19 is attached between a pair of left and right front slide frames 17 and 17 to form a U-shaped front portion. The movable frame 20 is formed, and a rear horizontal frame 21 is attached between the pair of left and right rear slide frames 18 to form a U-shaped rear movable frame 22. Each slide frame 17 is locked by a pin 23 so as not to slide.

Brackets 24 are attached to both longitudinal ends of the front horizontal frame 19 and both longitudinal ends of the rear horizontal frame 21, and support arms 25 are provided on the brackets 24 so as to be rotatable in the horizontal plane. A load receiving member 26 is attached to each of the support arms 25, and a load A is placed on each load receiving member 26.

As shown in FIGS. 4, 5, and 6, a plate 27 is attached to the upper surface of each bracket 24, and the plate 27 has first, second, and third fixing pin holes 28, 29, 30 are formed at intervals on an arc locus around the support arm rotation center 25a, and are supported by fitting the fixing pin 31 into the pin hole 32 of the supporting arm 25 from any one fixing pin hole. The arm 25 can be locked in three different postures.

Because of this, the luggage A can be placed across the upper portions of the left and right crawler belt type traveling bodies 6, 6, and the space between the left and right crawler belt type traveling bodies 6, 6 can be effectively used as a luggage installation space. Since it is possible, it is possible to place and carry a luggage having a size larger than the plane size of the cart. Further, the front and rear horizontal frames 19 and 20 are pulled toward the receiving frame 16 side as shown by the solid line in FIG. 1, and the support arms 25 are parallel to the receiving frame 16 as shown by the solid line in FIG. The posture makes the plane shape of the entire dolly compact and allows the dolly itself to travel in a narrow space with no load.

Moreover, if the support arm 25 is configured to project in the front-rear direction as shown by the one-dot chain line in FIG. 1, the front and rear luggage loading space becomes large, and the support arm 25 is indicated by the two-dot chain line in FIG. As shown in the figure, the left and right baggage installation space will be large if the projecting posture is left and right.

Further, by sliding the front / rear horizontal frames 19 and 21 forward and backward as shown by the three-dot chain line in FIG. 1, the luggage loading space can be made larger, and is significantly larger than the plan shape of the truck. Large luggage can be placed and transported.

Further, since the crawler type traveling body 6 is used for traveling, it is possible to stabilize the load even on rough terrain, and it is easy to handle obstacles, unevenness, etc., and hydraulic pressure (not shown) for driving the left and right sprockets 2 is used. By rotating the motor in the forward and reverse directions, super-spinning can be performed, so the turning half-diameter is small and it is possible to drive in narrow spaces. Further, since the engine and the like can be operated by radio control, it can be operated in an easy-to-operate place away from the truck.

[0016]

[Effect of device]

 Since the luggage can be placed and run over the support frames 25 located in front of and behind the crawler type traveling body 6, it is possible to transport the luggage having a size substantially the same as the plane size of the truck. By sliding the front and rear movable frames 20 and 22, and rotating the support arm 25, the overall plane size can be reduced or increased. It can be adjusted according to the situation, and when traveling by itself with an empty load, the plane size of the bogie can be minimized to drive in narrow spaces.

[Work]

Since the luggage can be placed and run across the front and rear movable frames 20 and 22 located in front of and behind the crawler-type traveling body 6, it is possible to carry a luggage having a size substantially the same as the plane size of the trolley. By sliding the front and rear movable frames 20 and 22, the overall plane size can be reduced or increased, so the plane size of the trolley can be adjusted according to the size of luggage to be transported, and the empty size can be adjusted. When self-propelled by a load, the plane size of the truck can be minimized to drive in a narrow space.
