Description

  The present invention relates to a transport cart.

At the construction site, a large amount of various types of waste such as residual soil, concrete glass, asphalt lump, brick piece, waste gypsum board, waste rebar is generated. The waste is loaded into a dump truck or the like and carried out. However, depending on the location conditions, the dump truck may not be able to approach the site where the waste is generated. In this case, the generated waste is sorted according to its type, packed in a bag such as a flexible container bag, transported to a truck crane (unic car) by a transport cart, and then transported to the truck crane together with the bag. .
Since the specific gravity of the waste is different, if the bag body is filled with waste having a large specific gravity, the load capacity of the transport cart or the load resistance of the bag body may be exceeded. When the load capacity of the bag body is exceeded, problems such as the bag body breaking when the bag body is lifted, the transport carriage becoming unstable, and the truck being overloaded occur.

In Patent Document 1, a flat ground is provided at the end of the rail of the material and equipment accumulation ground, a weighing platform for measuring the weight of each rail is provided on the flat ground, and the load of the transporter is measured for each rail. Methods have been proposed to prevent overloading of aircraft. The method proposed in Patent Document 1 is a large-scale method in which a large weighing platform is installed on a leveled flat ground, and the cost burden is large.
Patent Document 2 proposes a method for preventing overloading by loading a load of a cart using a coupler incorporating a sensor when towing a cart with a tow vehicle connected thereto. The method proposed in Patent Document 2 is to measure whether the loaded load exceeds the proper amount. If the load exceeds the proper amount, it cannot be prevented. It is necessary to load and unload luggage.

The figure which shows the cyclic | annular member which is an example of a loading amount instruction | indication part. The figure which shows the support | pillar provided with a some annular member. The figure which shows the support | pillar provided with a scale.

The transport cart of the present invention has four support columns on four sides of the transport table, and at least one of the support columns includes a plurality of load capacity instruction units installed at different heights according to the load object. It is characterized by.
A bag is placed on the transport cart, and various objects to be loaded are packed into the bag. Examples of loading objects to be packed in the bag include soil, sand, rock, metal scrap, plastic, wood, paper, resin pellets, rice, wheat, beans, and feed. Hereinafter, a description will be given of a transport cart used as a transport cart, which is used at a construction site and in which surplus building materials are packed in a bag.

  It is important to separate and collect surplus building materials generated at the construction site, since the processing after removal from the construction site differs for each type. Separate collection of surplus building materials and clarifying the loading capacity (collection amount) for each type not only prevents damage to the bag body, but also makes it easy to grasp the amount of surplus building material collected for each type, Effective for construction site management.

One embodiment of the transport cart of the present invention is shown in FIG.
The transport cart 1 according to one embodiment includes a cart body 2 including a transport platform 21. Four support columns 3 are provided on four sides of the carriage 21, and the support columns 3 include loading amount instruction units 31 a and 31 b and bag body connection members 32. Here, the example of the load amount instruction units 31a and 31b shown in FIG. 1 is a color band around which a color tape is wound. The color band can also be formed by applying a paint. A bag body 4 having a belt 41 for lifting is placed on the carriage 21. The bag body 4 is maintained in a state where the upper opening 42 is opened by the belt 41 being connected to the bag body connecting member 32. A bulletin board 5 is installed on one of the columns 3.

The cart main body 2 can be either a push cart or a pull cart that has an appropriate load capacity that can withstand the transport of surplus building materials. Since a large amount of surplus building materials can be transported at a time, it is preferable that the load on the carriage body 2 is large. However, if the amount of waste loaded becomes too large, the risk of collapsing or colliding will increase.
Here, at the construction site, the work carriage and the bag are standardized so that they can be used anywhere, and the specifications of the bag are the same as the “ton pack” with a load resistance of about 1 ton. Often doing. Since the load resistance of the bag is about 1 ton, the load on the carriage body is often determined within the range of 1000 kg to 1200 kg. By sharing the transport cart and the bag, it is possible to share the equipment used for a series of transports, and it is easy for the operator to learn.

  The support column 3 prevents the bag 4 loaded on the transport cart 1 from collapsing and falling, and also serves as a handle when pushed by a human hand. The support | pillar 3 is formed from metals, such as iron, aluminum, and stainless steel, a plastics, a timber. Metal hollow pipes are easy to grip and operate when pushed by hand. The support column 3 is detachable from the carriage 21, removes the support column 3 and loads a larger load than the carriage 21, removes the support column 3 when the carriage 1 is not in use, and stacks and stores the cart body 2. This is preferable because the space can be reduced.

  The bag body connecting member 32 is composed of a clamp, and is connected to the belt 41 of the bag body 4 to prevent the bag body 4 from falling and collapsing. Further, the upper opening 42 of the bag body 4 is maintained in an open state, and the bag body 4 can be easily packed with an object to be loaded. The bag connecting member 32 is not limited to a clamp, and a carabiner, a hook, or the like can be used. The bag body connecting member 32 is connected to the upper portion of the column 3 directly or via a chain or the like.

  The load amount instruction units 31a and 31b correspond to different types of surplus building materials and display the upper limit of the height at which the corresponding surplus building is loaded. In FIG. 1, a color band around which color tape is wound is provided above and below the support column 3, the lower color band is a load amount instruction unit 31 a corresponding to the concrete glass, and the upper color band is a load corresponding to the remaining soil. This is a quantity instruction unit 31b. Further, the number of loading amount instruction units is not limited to two, and is provided according to the number of types of loading objects. When the number of types of loading objects is too large, a plurality of types of loading objects having a specific gravity are grouped into one group, and a group including a plurality of types of loading objects is associated with the loading amount instruction unit.

  The load amount instruction units 31a and 31b are provided at positions where the weight of the load object loaded up to the height indicated by the load amount instruction unit is equal to or less than the upper limit of the weight, and displays the upper limit of the height at which the load object is loaded. The height of the load amount instruction unit is preferably set at a height at which the weight of the load object loaded up to the height indicated by the load amount instruction units 31a-d is 75% to 90% of the upper limit of the weight. By installing the load amount instruction units 31a-d at a height that is 90% or less of the upper limit of the weight, the weight of the load object can be set to the upper limit of the weight even in consideration of variations in the amount of packing and specific gravity in the actual loading operation. Is not exceeded.

  At least one strut is required to provide a load capacity indicator, but loading work is often performed from multiple directions, so it is appropriate to install it on two struts arranged diagonally. It may be provided on the column. In addition, when it is difficult to identify the load amount instruction unit corresponding to the load object among the plurality of load amount instruction units provided on one column, the unnecessary load amount instruction unit is hidden. It is preferable to make it possible to easily identify the load amount instruction unit corresponding to the load object by marking the corresponding load amount instruction unit.

An annular member having a visual recognition part can be used as the load amount instruction part. FIG. 2 shows an annular member 34 which is an example of a load amount instruction unit.
The annular member 34 has a visual recognition part 341 that can be viewed from only one direction of the annular member, and a screw 342 on the opposite side of the visual recognition part 341. In FIG. 3, the visual recognition part 341 is an opening. The visual recognition unit 341 is not limited to an opening as long as it can be viewed from only one direction, and coloring, arrows, and the like can also be used. Further, the screw 342 can be used as a visual recognition part. The annular member 34 is rotatable about the support column 3, and the tip of the screw 342 is fixed to the support column 3 by tightening the support column 3.

FIG. 3 shows an example of the column 3 provided with a plurality of annular members 34a-d.
Of the plurality of annular members 34a-d, the viewing portion 341b of one annular member 34b is on the outside, and the other annular members 34a, 34c, 34d are visible on the support column 3 standing on a transport cart (not shown). The parts 341a, c, and d are fixed so as to face inward. Of the plurality of annular members 34a-d, only the visual recognition part 341b of one annular member 34b corresponding to the loaded object faces outward, so that the worker can visually recognize only the visual recognition part 341b. The worker can easily determine the annular member 34b corresponding to the loaded object by the visual recognition unit 341b. When the visual recognition part 341b is an opening, in order to improve the visibility of the visual recognition part 3, it is preferable to color the outer periphery of the support column 3. The outer periphery of the support column 3 can be colored with a different color or the same color for each viewing portion by using color tape, paint, or the like.

  A scale indicating the height from the carriage can be provided on the column 3. In FIG. 4, the example of the support | pillar 3 provided with the scale 33 is shown. The scale 33 may be formed at a predetermined height or higher portion of the support column 3, and is provided at a height of 100 cm or more in the example shown in FIG. Since the support column 3 includes the scale 33, the load amount instruction unit can be installed at an appropriate height of the support column 3 without using a tape measure or the like. Since the scale 33 can be provided simply by being attached to the existing support 3, the scale 33 is preferably a seal.

  The transport cart 1 according to one embodiment includes a bulletin board 5. The bulletin board 5 describes types of waste corresponding to a plurality of load capacity instruction members. By showing the types of wastes with pictures and photographs, even foreign workers who do not understand Japanese can understand the posted content. By displaying appropriate information on the bulletin board 5, it is possible to prevent the worker from throwing in the wrong type of waste or being overloaded.
