Description

  The present invention relates to a carriage capable of placing and transporting heavy objects such as machines and their accessory parts.

  At construction sites, etc., transport carts are used as a means of easily transporting heavy items such as machines and their accessories. However, heavy items that fall from the transport cart can lead to serious accidents. There is a need for a transport cart that can safely and reliably transport the vehicle.

  In the prior art, a slip prevention member is formed on the mounting surface and a plurality of linear protrusions for preventing the slip of the load are formed, thereby preventing the fall of the load (patent) There is no description or suggestion of providing a groove portion extending from one side of the four sides of the mounting surface to the opposite surface to prevent the load from falling off.

  In the prior art, there is a technique for firmly connecting a transport cart to increase the amount of luggage carried by one worker at a time, or to reduce the number of movements required to carry the luggage (Patent Literature). 2), there is a description or suggestion about the safe transportation of the machine by placing a concave mounting surface near the center of gravity of each wheel of the carriage and placing each heavy machine leg on this. It has not been.

  By the way, when transporting the transport cart itself or storing the transport cart, it is a common practice to stack other carts on the one cart alternately in the longitudinal direction. However, since the carriage of the machine and its accessory parts needs to carry heavy objects, it is necessary that the carriage itself is made strong. Therefore, the carriage is preferably made of metal, and the carriage itself is slightly heavy. If such a stacking method is used and the whole collapses, it can lead to a serious accident.

  In addition, it is preferable that the carriage of the machine and the accessory parts has six wheels rather than four in order to carry heavy objects. In the case of six wheels, it becomes impossible or difficult to perform the above-described general stacking method because the middle two wheels are in the way.

  In the prior art, a transport cart with a push handle comprising a base plate, left and right rear wheels fixed in the front-rear direction, left and right front wheels, and a push handle provided on the base plate, Left and right engagement holes are formed in the direction of the left and right rear wheels and shifted forward from the left and right rear wheels. When the distance in the front-rear direction to each center of the joint hole is D1, and the distance in the front-rear direction from the rear end surface of the base plate to each center of the left and right rear wheels is D2, the left and right engagement holes are respectively D1. > D2 is formed at a position in the front-rear direction on the base plate satisfying D2, and when a plurality of the transport carts with the push handle are stacked, the upper transport cart with the push handle stands on the base plate. In use Then, the left and right rear wheels are engaged with the left and right engagement holes of the lower carrier carriage with the push handle in the use state in which the push handle is erected on the base plate. There is a technique of a transport cart with a push handle characterized in that it can be placed and stacked on a base plate (see Patent Document 3), but the cart is fixed while using a support column. There is no mention or suggestion.

  The first problem to be solved is that when a machine part, which is a heavy machine with a long dimension, is transported on a carriage, if the wheel gets caught on a ground projection or the like, the machine part will fall off. There is a need for a transport cart that can be transported reliably.

  The second problem to be solved is that when each leg of a machine composed of a main body part and a leg part is placed on a carriage and the wheel of the carriage is caught on a ground protrusion, the machine falls. Therefore, there is a demand for a transport cart that can be transported safely and reliably.

  The third problem to be solved is that the carriage of the machine and its accessory parts must be made of a solid body in order to carry heavy objects. Desirably, the bogie itself is slightly heavier, and the bogie wheels are preferably 6 wheels rather than 4 wheels. Therefore, there is a demand for means for stacking the bogies themselves and transporting them safely and reliably.

  The present invention is a transport cart, comprising a groove portion having a constant width that traverses or longitudinally crosses the mounting surface of the transport cart, and the bottom portion of the groove portion includes one end and the other end that are both ends in the length direction of the groove portion. The first feature is to exist at least.

  The present invention is a transport cart, which has a recessed mounting surface in a certain range recessed on the mounting surface of the transport cart, and four or more wheels attached to the back surface of the base plate of the transport cart. The concave mounting surface includes a point on a vertical line passing through the center of gravity of the entire center point of each attachment portion of each wheel.

  The present invention is a support column used when stacking and transporting or storing other transport carts having the same shape as the transport cart, and is attached to one or more support columns and a lower portion of the support columns. A support part and a projecting fitting part projecting from the support part or the lower part of the support part. The support pillar is placed on the transport carriage, and the other transport carriage is further provided thereon. In order to prevent the other transport cart from falling off, the support column is inserted into the vertical through-holes provided in the other transport cart when used, The carriage is stacked on the carriage, and the support portion abuts and supports the carriage when in use so that the column portion is upright, and the protruding fitting portion is In order to prevent the front / rear / left / right shift of the part, the groove, the vertical penetrating part, the hole, and other recesses provided in the transport carriage during use Or to a third feature that fits into the weighing table outer edge of the transport truck.

  Since the transport cart of the present invention has the first of the above characteristics, it is possible to roll even when a wheel is caught on a protrusion on the ground by transporting a machine part, which is a heavy object having a long dimension, on the groove. There is an advantage that it can be transported safely and securely without falling off.

  Since the transport carriage of the present invention has the second of the above characteristics, by carrying each leg of a heavy machine on the concave placement surface, the leg does not slip and fall off, There is an advantage that it can be transported safely and reliably.

  Since the support pillar of the present invention used when stacking and carrying another carriage with the same shape as the carriage on the carriage has the third feature, the carriage is fixed using the support pillar while being stacked. Thus, there is an advantage that even if the carriage is made of metal and heavy, and a six-wheel carriage is stacked, the carriage can be safely or reliably transported or stored.

  We realized the function of a transport cart that can safely and reliably transport machines that are long-sized accessories and heavy equipment consisting of a main body and legs. In addition, we have realized the function of a support pillar that can be transported safely and reliably even when stacking transport carts made of metal bases as six wheels with emphasis on load resistance.

The phrase “crossing or longitudinally crossing the placement surface” according to claim 1 refers to extending from one side of the placement surface to the opposite side, and not only in a direction perpendicular to the one side but also in an oblique direction. It also includes extending from one side of the mounting surface to the opposite side.

"Constant width" of claim 1, 5 of the weighing table of the width of "the delivery truck" according to accessories such as a long machine dimensions on need to be transported is placed in the groove portion, to claim 1 % To 90% is desirable, and 30% to 40% is particularly desirable. In the calculation related to the width of the base plate, it is assumed that the shape of the outer edge of the base plate is a rectangle or a square. It is considered as a rectangle or a square as what is not chamfered.

The “bottom part of the groove part” described in claim 1 is not necessarily required to exist over the entire groove part because it is necessary to place and transport an accessory part or the like of a machine having a long dimension in the groove part. It is sufficient that only the portion exists, and in particular, at least both ends in the length direction of the groove portion, that is, the outer edge portion of the base plate.

In addition, the “groove” according to claim 1 does not include a bent or curved groove in principle because it is necessary to place and transport an accessory part of a machine having a long dimension in the groove, but the side wall of the groove is not included. Even if the groove is curved and bent or curved, a space corresponding to the groove on the straight line of the “constant width” according to claim 1 is secured over both ends in the length direction of the groove. Needless to say, the case is included in the “groove”.

  The “certain range” described in claim 1 is the “determined range” described in claim 1, because each leg of a heavy machine is required to be transported on the “concave mounting surface” described in claim 1. It is preferably 3% to 90%, and particularly preferably 10% to 15%, of the entire area inside the outer edge of the “carriage carriage mounting surface”. In the calculation relating to the entire inner area of the outer edge, it is assumed that the shape of the outer edge is a rectangle or a square. As a non-processed item, it is considered to be rectangular or square.

  The “center point” according to claim 1 refers to the vicinity of the center of the “attachment portion” according to claim 1. Strictly speaking, the support body that supports the axle of the “wheel” according to claim 1 comprises: The gravity center of the force which pushes the "back surface of the platform of the said conveyance trolley" of Claim 1 vertically upward.

  The “center of gravity” according to claim 1 assumes that a force is applied evenly and perpendicularly to each “center point” according to claim 1, and the “back surface of the carriage carriage base” plane according to claim 1. Is an XY plane, and the origin O (0, 0) is arbitrarily set, and the “center of gravity” according to claim 1 is G (x, y). Each of the n “center points” according to claim 1 Are G1 (x1, y1), G2 (x2, y2),. . . , Gn (xn, yn), G (x, y) = (G1 (x1, y1) + G2 (x2, y2) + ... + Gn (xn, yn)) / n. This is so that the weight of the conveyed product is evenly distributed to each of the n wheels.
