Description

  The present invention provides a lower end corner portion of a transported object to serve as a fulcrum for standing up when the transported object, which is a variety of products that are bulky in weight, is transported in a so-called laid state at a predetermined place in a factory or the like. The present invention relates to an apparatus for assisting standing up of an object to be carried so that the standing work can be smoothly performed by placing and supporting.

In factories and other locations, for example, when various products to be manufactured are heavy in weight and have a plate-like shape that occupies a relatively large area, and various devices to be installed have a high height at the time of installation. When the vehicle is in a lying state, the conveyance may be carried out by a roller system in a so-called laid state. That is, a large number of rollers are arranged on a factory floor or other transport surface, and the object to be transported is moved on a transport plate such as an iron plate placed on the roller. Then, plate objects, various devices, etc., which are the objects to be transported, are stood and stored or installed at predetermined places. At the time of the standing work at the time of storage or installation, for example, it is lifted by being lifted from one end side by an overhead crane.
nothing special

  However, when the object to be transported is lifted from one end of the crane with an overhead crane, etc., the other end, which is the fulcrum, remains free and is not firmly fixed and supported even temporarily. In some cases, the left and right can move freely. For example, when there is an on-site worker in the vicinity, this free shift movement is dangerous in performing the work, and therefore, some kind of measure for restricting the free movement is necessary.

  Therefore, if the field worker directly supports the other end, the standing of the transported object which may be bulky or the moving work is unstable during the work. Is very dangerous. Moreover, depending on the case, an unreasonable working posture is forced on the field worker, which is not preferable in terms of preventing the occurrence of occupational accidents.

  Therefore, the present invention was created in view of the conventional circumstances as described above, and its purpose is to lower the lower corner portion of the object to be transported which becomes a fulcrum during the standing work when the object to be transported after standing is raised. It is intended to make it possible to smoothly and safely stand up the object to be transported. It is another object of the present invention to provide a standing support device for an object to be transported that is simple in configuration and easy to handle.

In order to solve the above-described problems, in the present invention, a frame carriage 1 that can be moved by a traveling roller 6 fitted to a roller shaft 5 that is arranged at the front and back, and a frame carriage 1 that can be swung back and forth. The tilting mechanism 10 includes a tilting mechanism 10 that supports the lower end corner portion of the article C to be carried and is to be erected. The tilting mechanism 10 rotates on the frame carriage 1 with its peripheral edge in contact with the roller shaft 5 of the frame carriage 1. A rolling plate 11 that can be freely configured, and a tilting plate 18 that is fixed to the rolling plate 11 and that is substantially L-shaped when viewed from the side surface on which the lower end corner of the object C is placed. It is characterized by.
Further, the rolling plate 11 of the tilting mechanism 10 is cut out in a substantially fan shape of about 1/4 when viewed from the side surface, and the remaining almost 3/4 arc-shaped peripheral edge is free on the front and rear roller shafts 5 respectively. Each roller follower 13 fitted in a rotating state is in contact with each other so as to be rotatable.
The tilting plate 18 is fixed to a substantially L-shaped linear notch edge surface as viewed from the side surface of the rolling plate 11 so as to span between the left and right rolling plates 11.
In the rolling plate 11, guide pins 15 inserted and fixed to the left and right side plates 3 of the frame carriage 1 are formed in the rolling plate 11 itself so as to have an arc shape with respect to the rotation center of the rolling plate 11. It is possible to provide guide means 14 that is slidably fitted to a guide portion 16 that is formed in a hole shape.

In the standing assist device for a transported object according to the present invention configured as described above, the lower end corner of one of the transported objects C to be erected is supported and placed on the tilting mechanism 10. Thus, by lifting the other side of the article to be transported C, the object to be transported C is erected smoothly with the support placement portion on the tilting mechanism 10 as a fulcrum.
Even if the lower end corner of one of the objects to be moved moves while the object to be conveyed C is lifted up, the traveling roller 6 of the frame carriage 1 follows and moves the fulcrum position while raising the object to be conveyed C. Let
The rolling plate 11 in the tilting mechanism 10 abuts on the roller follower 13 fitted in the roller shaft 5 of the frame carriage 1 in a free rotation state, so that the weight of the transported object C supported and placed on the tilting mechanism 10 Is transmitted to the traveling surface via the traveling roller 6 and supported, and does not apply a local weight load to each part of the tilting mechanism 10 and the frame carriage 1.
The guide means 14 swings and guides the tilting mechanism 10 in relation to the frame cart 1 and does not separate the tilting mechanism 10 from the frame cart 1 and disassemble it.

  Since the present invention is configured as described above, for example, when a large and bulky transported object C is transported and stood up after transporting, the transported object that becomes a fulcrum during the standing work. It is possible to smoothly and safely stand up the transported object C when placing and supporting the lower end corner of C and lifting the other side. In addition, since the tilting mechanism 10 that swings is mounted on the traveling frame cart 1, safety is required even in the vicinity of the site during standing work, so that safety can be achieved, and the configuration is simple and handled. Is also easy.

  That is, in the present invention, this comprises a movable frame carriage 1 and a tilting mechanism 10 attached to the frame carriage 1 so as to be swingable back and forth. A rolling plate 11 whose periphery is in contact with the shaft 5 and is rotatable on the frame carriage 1, and is fixed to the rolling plate 11, and is almost seen from the side surface on which the lower end corner portion of the object C is placed. This is because the L-shaped tilting plate 18 is provided. This makes it possible to carry the load with respect to the transported object C, maintain the fulcrum during the standing work of the transported object C, and move the support fulcrum when the transported object C is lifted.

  Further, the rolling plate 11 of the tilting mechanism 10 is in contact with each of the roller followers 13 whose arc-shaped peripheral edges are fitted to the front and rear roller shafts 5 in a free rotating state. Therefore, the weight of the transported object C supported and placed on the tilting mechanism 10 is transmitted to and supported by the traveling surface via the traveling roller 6, so that it can be locally applied to any part of the tilting mechanism 10 and the frame carriage 1. Therefore, it can be used safely with little risk of breakage or destruction.

  In the tilting mechanism 10, the tilting plate 18 spanned and fixed between the left and right rolling plates 11 is substantially L-shaped when viewed from the side, so that the lower end corner portion of the object C to be erected can be reliably and stably raised. Can be supported. Moreover, even if the tilting plate 18 swings before and after the standing work, the posture stability of the transported object C is maintained even before and after the standing work because either side of the tilting plate 18 itself is parallel to the traveling surface. it can.

  Since the rolling plate 11 is provided with guide means 14 that slidably fits guide pins 15 inserted and fixed to the left and right side plates 3 to arcuate guide portions 16 formed on the rolling plate 11 itself. When the tilting mechanism 10 is swung with respect to the frame carriage 1, the tilting mechanism 10 can be safely swung within a certain range without being separated from the frame carriage 1 and disassembled.

  In addition, the code | symbol attached | subjected in the means for solving said subject, and each item of the effect of invention was attached | subjected in order to make easy reference with the part which shows each structure part described in drawing. The present invention is not limited to these descriptions, structures, shapes, and the like indicated by reference numerals and the like in the drawings.

  The best mode for carrying out the present invention will be described below with reference to the drawings. A reference numeral 1 shown in the figure denotes a frame carriage, which is framed in a substantially rectangular shape when viewed from the front and back, left and right side plates 2 and 3, and the frame carriage 1 itself is pulled on the outer side surfaces of the front and rear side plates 2, for example. A connecting arm 4 having a connecting hole for opening is projected in a pair on the left and right.

  Between the left and right side plates 3 in the frame carriage 1, front and rear, left and right traveling rollers 6 are rotatably fitted to roller shafts 5 supported at the front and rear portions of the frame carriage 1. The traveling roller 6 itself is fitted to the roller shaft 5 via ball bearings 7 arranged in a plurality of rows therein so as to rotate smoothly. The left and right traveling rollers 6 are arranged on the left and right outer sides of the central side plate 8 disposed and fixed between the front and rear side plates 2 along the longitudinal direction of the frame carriage 1 at the central position in the frame carriage 1. It is. The roller shaft 5 protrudes from one of the left and right side plates 3 and is displaced in the left-right direction by the key plate 9 fixed to the outer surface of the side plate 3 so as to be fitted in the key groove formed in the protruding portion. Regulations are maintained without causing them.

  Such a frame cart 1 is equipped with a tilting mechanism 10 that can swing in the front-rear direction. The tilting mechanism 10 has a rolling plate 11 whose periphery is in contact with the roller shaft 5 of the frame carriage 1 and is rotatable on the frame carriage 1, and is fixed to the rolling plate 11, and the lower end of the conveyed object C. A substantially L-shaped tilting plate 18 as viewed from the side surface on which the corner is placed is provided.

  The rolling plate 11 is cut out in a substantially fan shape, which is approximately ¼ when viewed from the side, and is free on the outer peripheral surface of the roller shaft 5 with, for example, a roller follower 13 at the remaining arc-shaped peripheral edge of approximately ¾. It is in contact with each other, and can sufficiently withstand the load caused by the object C to be supported and placed to stand. This rolling plate 11 is arranged in a pair, for example, inside the left and right side plates 3 on the left and right sides of the frame carriage 1, and is suitable between the left and right rolling plates 11 so that it can sufficiently withstand the load of the object to be transported C. Several auxiliary rolling plates 12 may be arranged.

  Both the rolling plate 11 and the auxiliary rolling plate 12 have the same shape (see FIGS. 2 and 3). In the drawing, the center position of these rotations and the notch edges cut out in an L shape are the frame carriage 1. Is located above the left and right side plates 3. That is, it is considered that the article C to be raised is supported and placed on the tilting mechanism 10 and does not descend downward from the upper surface of the frame carriage 1 when it is shaken.

  The left and right rolling plates 11 have their arcuate peripheral edges rotatably abutting on the respective roller followers 13 fitted to the front and rear roller shafts 5 in a free rotating state. It is supported. The roller follower 13 on which the rolling plate 11 is placed and supported is disposed inside the left and right side plates 3 in the frame carriage 1 on which the rolling plate 11 is disposed (see FIG. 4), and the weight of the conveyed object C Is transmitted to the traveling surface via the tilting plate 18, the front and rear roller followers 13, and the traveling roller 6.

  The left and right rolling plates 11 themselves are also smoothly swayed by guide means 14 formed on the left and right side plates 3 in order to prevent detachment and disengagement from the frame carriage 1. That is, the guide means 14 slidably fits, for example, a guide pin 15 inserted and fixed to the left and right side plates 3 to a guide portion 16 formed on the rolling plate 11 itself so as to have an arc shape with respect to the rotation center of the rolling plate 11. Combined. Since the tilting angle range of the tilting mechanism 10 itself is set within approximately 90 degrees, the arcuate length of the guide portion 16 also corresponds to this. The guide portion 16 is formed in a groove shape as shown in the figure on the side surface of the rolling plate 11 or in a hole shape (not shown).

  Unlike the rolling plate 11, the auxiliary rolling plate 12 is not formed with the guide portion 16, and is disposed between the rolling plates 11 as a single sheet or a plurality of sheets depending on the weight of the article C to be erected. In the drawing, the peripheral edge is in contact with the roller follower 13 disposed between the pair of central side plates 8 (see FIG. 4).

  The tilting plate 18 is formed on the rolling plate 11 and further on the auxiliary rolling plate 12 by an L-shaped straight cut-out edge as viewed from the side surface, for example, by an embedded screw that does not protrude on the surface of the tilting plate 18 itself. The left and right rolling plates 11 are fixed so as to span each other. The tilting plate 18 is formed as a divided flat plate so as to be fixed to each of the linear notch edges of the rolling plate 11 and the auxiliary rolling plate 12. It may be integrally formed in a letter shape. The surface of the tilting plate 18 is formed with an appropriate number of anti-slip ridges 19 having a triangular shape in cross section, for example, along the horizontal direction of the frame carriage 1.

  Next, an example of the use of this will be described. For example, when the object to be transported C transported to a predetermined place on the transport surface is erected, it is brought to the left and right corners of one lower end corner of the object to be transported C and kept waiting. Then, as shown in FIG. 5, the lower end corner portion on the one end side of the article to be transported C is supported and placed on the tilting mechanism 10 of the frame carriage 1 of the present invention device, and the other end portion of the object to be transported C. For example, the side is connected to a wire hook from a crane L. Next, when the wire or the like is pulled and pulled up by the crane L, the transported object C is lifted with the tilting mechanism 10 portion of the support placement position as a fulcrum, and the fulcrum position moves with the lifting. The traveling roller 6 in the frame carriage 1 moves following the rolling. In addition, the standing assistance apparatus which concerns on this invention is not restricted to the case where it is set as the pair-like arrangement | positioning which becomes each two places of the right-and-left part of the standing fulcrum position in the to-be-conveyed object C, One place may be sufficient, Furthermore, 3 It may be a plurality of places more than the place, and is appropriately selected according to the weight, size, etc. of the object C to be transported.

  At this time, if necessary, a stopper device can be incorporated in advance so that the traveling rotation of the traveling roller 6 in the frame carriage 1 is stopped. Further, during the lifting work, the standing work can be performed while adjusting the movement of the frame carriage 1 by the adjusting wire connected to the connecting arm 4 or the like.

It is a perspective view which shows the best form for implementing this invention. It is a partially cutaway side view. It is a side sectional view similarly. Similarly, it is a front sectional view. It is a schematic side view in an example of a use condition similarly.
