  It is an object of the present invention to provide a multi-function lifting machine combined carriage and an auxiliary tool configured to be capable of improving work efficiency quickly and easily with respect to the object, and realizing cost reduction. is there.

The invention according to claim 1 is integrated with a pulling portion whose tip is inclined at an acute angle, and a carriage constituted by a roller having a rotating shaft, with an operation handle constituted by a bent portion and a handshake portion. It is a multi-function lifting machine combined carriage that is characterized by the above. Specifically, by inserting a lifting part whose tip is inclined at an acute angle into the lower end of the object (withdrawal of square material etc. of the dismantling structure), and pushing down the handshake part made up of the operation handle integrated with the carriage The object is pulled up. A main example is an operation that is integrated with the carriage by inserting a lifting part whose tip is inclined at an acute angle into the lower end of a square member (rafter, etc.) of the target object attached to the uneven structure material with nails. By pushing down the handshake part made of a handle, both the square material (the joists, rafters, etc.) of the object and the nails driven into the object can be pulled up and separated from the structure as shown in FIG.
The “uneven structure material” will be described. For example, in the case of a square bar, the uneven shape described above refers to a large pull or the like that supports the target object (a joist etc.) of the flooring. Further, it means a main building or the like that supports the above-mentioned target object (such as a rafter) in a cabin. Therefore, when pulling up and pulling out the above-mentioned squares (the joists, rafters, etc.) of the object, the width of the squares (extracts, purlins, etc.) is limited (around 10.5 cm). In the shape of a carriage composed of a plurality of wheels at both ends, it is difficult to move the square member (such as a large puller or a purlin) because there is a risk of dropping or the like during operation.
Therefore, the present invention does not lift the multifunction lifting machine combined carriage to the position of the object attached to the uneven structure material with nails by configuring the wheel part in a roller shape, Since it only pushes, it does not require the effort to lift and carry. Moreover, you may provide the vehicle part one size larger than the diameter of a roller part in the both ends of a roller part. As an effect by this, it is possible to prevent the wheel from being removed by the vehicle portions at both ends corresponding to the width of the above-mentioned square members (such as joists and rafters) at the roller portion.
Therefore, it can be easily moved and the working efficiency is improved.
On the other hand, by inserting a lifting portion whose tip is inclined at an acute angle into the lower end of an object (light weight object, furniture, etc.) and pushing down the handshake portion formed of an operation handle integrated with the carriage, FIG. As described above, the object is pulled up and can be pulled back and forth, so that it can be easily moved and transported.
In addition, as long as the floor surface is smooth and stable, the roller portion formed of the rotating shaft may be configured by a caster formed of a plurality of vehicle units.

According to a second aspect of the present invention, there is provided a square-shaped portion that can be inserted into the rear end of the lifting portion whose tip is inclined at an acute angle so that the lifting portion of the multifunction lifting machine combined carriage of claim 1 can be attached and detached. An assisting device, wherein a back plate having a shape standing on the square-shaped portion is integrated. Specifically, the lifting part of the multi-function lifting machine combined carriage according to claim 1 is inserted into the square-shaped part at the rear end of the lifting part whose tip is inclined at an acute angle, and then the object (disassembly structure) The object is pulled up as shown in FIG. 5 by pushing it down into the lower end of the slab, etc. It can be moved and transported easily because it can be pulled back and forth.

  Since the invention described in claim 1 is a cart composed of a roller having a rotating shaft when lifting, moving, and transporting the object (drawing of a square member or the like of the dismantling structure), the object When pulling out the squares, etc., a trolley consisting of a roller consisting of a rotating shaft is used even if it touches the surface of a complex obstacle (node, warp, nail head, etc.) or the above uneven structure By doing so, it can be easily overcome and moved, and the work efficiency can be improved. One of the objects (lightweight objects, furniture, etc.) is a cart that consists of a roller consisting of a rotating shaft when it is lifted, moved, or transported. No jacks are used. Therefore, since the lifting, moving, and carrying can be performed simultaneously, the work efficiency can be greatly improved with less cost burden.

  According to the second aspect of the present invention, an object having a height, width, and depth (disassembly structure) indoors and outdoors can be provided by detachably attaching the auxiliary tool 4 to the multi-function lifting machine combined carriage of claim 1. It is possible to safely pull up, move, and transport items such as square materials, articles of light weight and furniture). Moreover, since it pulls up by the principle of a lever, a clearance gap can be ensured without requiring a sleeper etc. everywhere. Furthermore, work efficiency can be improved without damaging the lower end of articles, tools, and material boxes such as furniture.

  Since the present invention has a configuration as described above and is lightweight and compact, a plurality of operations can be easily performed without requiring a large force. Therefore, one person can insert a sleeper or a dolly into the lower end of an object to be cut (such as pulling out squares of a demolished structure, light weight items, furniture, etc.), so that even one person can use furniture, items, concrete, etc. Lifting, moving and transporting the side groove cover etc. can be done easily. In addition, since the structure is simplified, a small turn can be made in a particularly narrow and complicated place, and it is convenient for storage and carrying.

  In addition, as a disaster prevention measure, the width of the lower surface, which is the fulcrum of the conventional long bar, is wide and wide, so even if the balance is lost to the left and right, the risk of rollover etc. can be prevented, and the structure and handling method Because it is easy, it can be used easily by women and not by skilled workers, so it is effective in emergency situations such as securing and removing gaps in rubble such as buildings due to earthquakes and other disasters, and rescue operations at accident sites such as vehicles .
