[0007] Hereinafter, a lifting machine A according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. In addition, in the following explanation, directions are defined as the building B side of hoist A being the "front", the side opposite building B being the "rear", the width direction of hoist A being the "left and right", and the lifting and lowering direction of hoist A being the "up and down", and these "front and back, left and right, up and down" are shown in each figure.

[0008] [Unloader configuration] The hoist A is used to hoist a large, heavy load C, such as a sash window, to a high place, such as the second floor or higher, of a building, and is freely disassembled and assembled. As shown in Figure 1, the hoist A comprises one pillar 1, a base 2, a loading platform 3, a hoist 4, and a hoist support member 5. The loading platform 3 suspended from the hoist 4 is raised and lowered along the axial direction of the pillar 1 erected on the base 2 by the raising and lowering action of the hoist 4.

[0009] [Strut configuration] As shown in Figs. 1 and 4, the support 1 is made up of a plurality of support members 10, 11, and 12 (three parts in the figure) that can be separated in the axial direction. The support members 10, 11, and 12 are square pipes of the same cross-sectional shape, and are connected together along the axial direction by inserting a connecting joint 100 between the ends of the support members 10, 11, and 12. The connecting joint 100 has a rectangular cross-sectional shape that allows it to be inserted into the inner periphery of the support members 10, 11, and 12 without rattling and with a frictional force that allows it to be easily removed.

[0010] The first stage (lower) support member (hereinafter referred to as the "lower support member") 10 is inserted into the inner periphery of a support tube 20 (described below) provided on the base portion 2 without rattling and with a frictional force sufficient to allow it to be easily removed. A second stage (middle) support member (hereinafter referred to as “middle support member”) 11 is connected to the upper end of the lower support member 10 via a connecting joint 100. The third stage (upper) support member (hereinafter referred to as the "upper support member") 12 is connected to the upper end of the middle support member 11 via a connecting joint 100, and a hoist support member 5 is detachably inserted into the upper end of the upper support member 12.

[0011] The lower support member 10, the middle support member 11, and the upper support member 12 are each adjusted to a different length, and as shown in Figure 1(a), the height of support member 1 when all connected is set to a height that allows cargo to be lifted to the top floor of a three-story building B. In addition, by not connecting the upper support member 12 and instead inserting the hoist support member 5 detachably into the central support member 11, the height can be set to enable lifting to the top floor of a two-story building (not shown). Moreover, in order to accommodate a building having four or more floors, the length of the support 1 may be extended by successively adding intermediate support members 11 (not shown).

[0012] [Effect of Support] The support pillar 1 having the above-described configuration is formed by connecting a lower support member 10, a middle support member 11, and an upper support member 12, and therefore can be made long enough to raise the loading platform 3 to the required height. Furthermore, the support 1 can be freely separated into the support members 10, 11, and 12, which are short in length and compact when separated, making them convenient for transport and storage. Furthermore, since the lower support member 10, the intermediate support member 11 and the upper support member 12 are connected to each other by inserting them via the connecting joints 100, the connecting and separating operations can be carried out easily and quickly. The number of pillars 1 is not limited to one as illustrated, but may be two, in which case the pillars 1 may be arranged side by side in a left-right or front-back direction (not shown). Furthermore, when two pillars 1 are used, the hoist support member 5 can be attached to the upper pillar member 12 of either pillar 1.

[0013] [Base configuration] As shown in FIGS. 1, 2 and 5, the base portion 2 maintains the upright state of the support column 1 inserted into the support tube 20, and includes the support tube 20 and a base portion main body . The support tube 20 is a square pipe, and is fixed to the center of the front surface of the base tube 210 of the base portion main body 21 with its opening facing up and down. The fixing structure of the support tube 20 is such that the support tube 20 is placed between two angles 22 fixed to the front side of the base tube 210, and the support tube 20 and the angles 22 are fixed together by welding, bolting, or the like. The fixing structure of the support tube 20 may be a structure in which the support tube 20 is directly fixed to the front side of the base tube 210 by welding or bolting, without using the angle 22. A receiving portion 201 for receiving the lower support member 10 is provided on the lower inside of the support tube 20. The lower support member 10 inserted into the support rod 20 is received by the receiving portion 201 (see Figure 2(a)), thereby preventing the lower support member 10 from slipping out from the bottom of the support tube 20. The inserted lower support member 10 is fixed by bolts fastened to the front surface of the support tube 20, and can be removed from the support tube 20 by loosening the bolts.

[0014] As shown in FIG. 5, the base portion main body 21 includes the above-mentioned base tube 210 and an expansion body 211. The base tube 210 is a square pipe to which the expansion body 211 is connected, and is disposed with its longitudinal direction in the left-right direction. Rubber cushioning material 203 (see Figure 2) is attached to the underside of both ends of the base tube 210. This cushioning material 203 absorbs unevenness in the installation surface, preventing rattling and shifting of the hoist A when installed.

[0015] As shown in FIG. 5, the extension bodies 211 are a pair of left and right extension bodies, and each extension body 211 includes a slide tube 212 and a leg connecting tube 213 . The slide tube 212 is a square pipe, and is inserted coaxially into the left and right openings of the base tube 210 so as to be freely insertable and removable and slidable. In addition, as shown in Figure 5(a), the slide tube 212 is fixed to the base tube 210 by bolting it to the top and front of the base tube 210, and as shown in Figure 5(b), it can be attached and detached from the base tube 210 and the amount of protrusion can be adjusted by loosening the bolts.

[0016] As shown in Figure 5, the leg connecting tube 213 is a square pipe with the same opening size as the base tube 210, and is connected to the end of the protruding side of the slide tube 212 with its longitudinal direction in the front-to-rear direction perpendicular to the axis of the slide tube 212. A cushioning material 203 identical to the cushioning material 203 attached to the base tube 210 is attached to the front end side of the lower surface of the leg connecting tube 213. A connecting tube 215 to which the slide tube 212 is connected is fixed to the side surface of the leg connecting tube 213 opposite the protruding end of the slide tube 212 with its axis parallel to that of the slide tube 212 . The connecting pipe 215 is a square pipe having the same opening size as the leg connecting pipe 213, and the slide pipe 212 is inserted coaxially into this connecting pipe 215. The inserted slide tube 212 is fixed to the connecting tube 215 from the front side with a bolt, so that the slide tube 212 is connected in an immovable state, and can be removed from the connecting tube 215 by loosening the bolt. The slide tube 212 is usually inserted and fixed, but can be replaced with a slide tube 212 of a different length depending on the situation, or can be removed for the purpose of improving efficiency during storage or transportation.

[0017] A leg tube 214 is connected to the leg connection tube 213 of the expandable body 211 . As shown in FIGS. 5(a) and 5(b), the leg pipe 214 is a square pipe, and is inserted coaxially into the front opening of the leg connecting pipe 213 so as to be freely insertable and removable and slidable. The leg tube 214 can be slid in the insertion / removal direction (front-rear direction) relative to the leg connecting tube 213 to adjust the amount of protrusion. An adjuster 204 is screwed into the front end of the leg tube 214, and the height position can be adjusted by rotating this adjuster 204 in the tightening or loosening direction, thereby making it possible to level the base body 21.

[0018] [Effect of the base part] The base portion 2 having the above-described configuration supports the lower support member 10 of the support column 1 in a detachable manner by a simple configuration in which the support tube 20 is inserted and removed, so that the erection work of the support column 1 can be performed easily and quickly. In addition, since the base body 21 is integrated with the three components, the base tube 210, the extension body 211, and the leg tube 214, in a simple configuration that allows them to be easily attached and detached by simply inserting and removing them, the base body 21 can be easily and quickly divided into three parts and assembled. The base body 21 divided into three parts is compact, which is convenient for transport and storage. Furthermore, since the expansion body 211 inserted into the base tube 210 and the leg tube 214 inserted into the leg connecting tube 213 of the expansion body 211 are freely slidable, the amount of protrusion of the expansion body 211 relative to the base tube 210 and the amount of protrusion of the leg tube 214 relative to the leg connecting tube 213 can be adjusted as desired by the simple method of sliding. By adjusting the amount of protrusion of the extension body 211 and the leg tube 214, the base part 2 can be installed normally regardless of the shape of the installation location or obstacles, and can be installed in a balanced manner according to the height of the support 1.

[0019] [Cargo configuration] As shown in Figs. 1 to 3, the loading platform 3 is adapted to move up and down along the support pillars 1 with a load C placed thereon. As shown in FIGS. 3 and 6, the loading platform 3 has a back portion 30, a bottom portion 31, and a slider 6, and the slider 6 is disposed so as to surround the outside of the support pillar 1. The loading platform 3 has a bottom 31 disposed at the front lower end of a rear portion 30, and a slider 6 attached to the rear of the rear portion 30. As shown in Figure 6, the back portion 30 is composed of two back support rods 301 arranged at a distance from each other in the left-right direction, and an upper back support rod 302 fixed so as to span the upper ends of the two back support rods 301. The distance between the inner surfaces (opposing sides) of the two backrest rods 301 is equal to the overall width of the slider 6, and the slider 6 is attached to the inner surfaces of the two backrest rods 301. The upper backrest rod 302 has a length corresponding to the overall width of the loading platform 3, and supports the load C placed on the bottom 31, while at the same time fixing the backrest rods 301 together, thereby preventing the backrest rods 301 from wobbling. Additionally, the upper back support rod 302 is provided with two extension rods 303 protruding from the left and right ends. The extension rod 303 is freely slidable left and right relative to the upper support rod 302 and is also freely attachable and detachable, so that the amount of protrusion can be adjusted to match the width of the load C and it can be attached and detached as needed.

[0020] The bottom portion 31 is for placing the load C thereon, and as shown in FIG. 6, is formed in a rectangular shape in plan view having a front-to-rear width that allows the load C to be placed thereon reliably. As shown in Figure 7, the bottom 31 and the back support rod 301 are supported on the lower end of the back support rod 301 so that they can rotate freely around a left-right axis, and by rotating them, the bag can be placed in a load-receiving state as shown in Figure 6 and in a stored state as shown in Figure 7. In the load-receiving state, as shown in FIG. 6, the bottom portion 31 protrudes forward at a substantially right angle from the back portion 30, and a load C can be placed on the upper surface. In the stored state, as shown in FIG. 7, the back portion 30 and the bottom portion 31 are folded so as to face each other in parallel. At this time, by removing the slider 6 from the rear surface portion 30, there is no protrusion on the rear surface side of the rear surface portion 30, so that the rear surface portion 30 can be efficiently transported and stored without being bulky during transportation or storage. The support structure of the bottom 31 is a structure in which two angle bars 312 fixed to the rear surface of the bottom 31 with their longitudinal direction in the up-down direction are supported by the back support rod 301 from the left and right, and a stopper (not shown) is provided to keep the bottom 31 at an approximately right angle to the back portion 30 when in the load-receiving position.

[0021] [Slider configuration] As shown in Figures 2, 3, and 6, the slider 6 is equipped with a pulley mounting portion 60 for mounting a pulley 41 around which the wire 40 of the hoist 4 is wound, and a guide roller 61 for guiding the raising and lowering of the slider 6 along the support 1. As shown in FIG. 6, the slider 6 is formed in a frame shape by arranging frame rods 620 above and below and connecting the frame rods 620 with vertical rods 621 to form left and right frame bodies 62, and connecting the left and right frame bodies 62 with upper and lower connecting rods 622. The front end of the frame body 62 is attached to the rear portion 30 by bolts, and by removing the bolts, it can be removed from the rear portion 30 as shown in FIG. 7. In FIG. 6(c), the upper frame rod 620 of the right frame body 62 is the portion where the pulley attachment part 60 is provided, and is longer than the other three frame rods 620.

[0022] [Pulley mounting configuration] As shown in FIG. 8, the pulley mounting portion 60 is hook-shaped, and with the hook portion 601 on the rear end side exposed and facing downward, the support portion 602 connected to the hook portion 601 is inserted into the rear end of a frame rod 620 made of a square pipe, and the front end portion of the support portion 602 is supported by a left-right axis 603 so as to be freely rotatable. As shown in Figures 8(a) and (b), this type of pulley mounting portion 60 maintains the U-shaped pulley support 42, which supports the pulley 41, engaged with the frame rod 620 by the hook portion 601 of the pulley mounting portion 60 engaging with the rear end of the underside of the pulley support 42. The distance between the lower end of pulley 41 and the inner lower end face of pulley support 42, and between the left and right inner faces of pulley support 42, is larger than the size of the end face of frame rod 620, so that the front open part of pulley support 42 can be fitted in from the rear end of frame rod 620. To attach the pulley 41, as shown in Figure 8 (c), while holding the pulley mounting portion 60 in a rotated upward position, the front open portion of the pulley support 42 is fitted into the rear end of the frame rod 620, and the pulley mounting portion 60 is rotated downward to engage the hook portion 601 with the rear end of the underside of the pulley support 42, thereby attaching the pulley 41 to the slider 6. To remove the pulley 41, the pulley attachment portion 60 is rotated upward to disengage the hook portion 601, and the pulley support body 42 is pulled out while maintaining the disengaged state, thereby enabling removal. The rotation range of the pulley attachment portion 60 is a range in which the hook portion 601 does not interfere with the attachment and detachment operation of the pulley support body 42 at the upper rotation limit.

[0023] [Guide roller configuration] As shown in Figure 6 (c), the guide rollers 61 are journalled on the inside of the upper and lower frame rods 620 on both the left and right sides so as to face the front and rear surfaces of the support 1. When the slider 6 rises and falls, the guide rollers 61 roll against and come into contact with the front and rear surfaces of the support 1, allowing the slider 6 to rise and fall smoothly. This ensures that the loading platform 3 rises and falls smoothly as the slider 6 rises and falls.

[0024] Such a slider 6 can be fixed to the loading platform 3 and inserted into the support 1 so that the guide rollers 61 face the front and rear surfaces of the support 1, thereby attaching the loading platform 3 to the support 1. When inserting the slider 6 into the support 1, it is advisable to insert the slider 6 from above the lower support member 10 in a state in which only the lower support member 10 is erected on the base portion 2. Then, by sequentially connecting the middle support member 11 and the upper support member 12 after the slider 6 is inserted, the loading platform 3 can be attached to the support 1 in a state in which it can be raised and lowered freely.

[0025] [Effect of the loading platform] The loading platform 3 having the above-described configuration can be switched between a load receiving state and a load storing state by a simple operation of rotating the bottom portion 31 relative to the back portion 30. A slider 6 is attached to the loading platform 3 in the loading state, and the loading platform 3 can be attached by a simple operation of inserting the slider 6 from above into a lower support member 10 erected on the base portion 2. In the stored state, the loading platform 3 can be made compact by removing the slider 6 and folding the bottom 31, so that it can be efficiently transported and stored without taking up too much space during transportation or storage. In addition, the pulley mounting portion 60 provided on the slider 6 allows the pulley 41 around which the wire 40 of the hoist 4 is hung to be attached and detached to the slider 6 by a simple action of rotating the pulley mounting portion 60 to engage and disengage the hook portion 601 with the pulley support body 42. In addition, when the loading platform 3 is raised or lowered, the guide rollers 61 contact the front and rear surfaces of the support 1 to guide the lifting or lowering of the slider 6, so that the loading platform 3 can be raised or lowered smoothly without rattling, thereby preventing the load C from shifting or the like and enabling the load C to be transported reliably.

[0026] [Hoist configuration] As shown in FIG. 3, the hoist 4 incorporates a winding section (not shown) that winds up the wire 40, one end of the wire 40 is connected to this winding section and wound around it, and a pulley 41 is hung around the wire 40. The hoist 4 is detachably suspended via a hook 43 from a hoist support member 5 attached to the top of the support column 1 . A hook 401 is attached to the other end of the wire 40, and this hook 401 is detachably hooked onto the hoist support member 5, thereby making the other end of the wire 40 immobile. The pulley 41 is a movable pulley around which the wire 40 is wound and one end of which moves up and down due to the wire 40 being wound up and let out at the winding section. When the wire 40 is wound up and let out at the winding section, the pulley 41 rises and falls, and the raising and lowering of the pulley 41 raises and lowers the loading platform 3.

[0027] [Effect of hoist] The hoist 4 having the above-described configuration can be easily attached by simply hooking it onto the hoist support member 5, and can also be easily removed by detaching it from the hoist support member 5. In addition, by hooking the hook 401 of the wire 40 onto the hoist support member 5, the pulley 41 becomes a movable pulley structure, and by attaching this pulley 41 to the slider 6 via the pulley mounting part 60, the cargo bed 3 can be raised and lowered with a small hoisting force. As described above, the pulley 41 can be attached to and detached from the slider 6 via the pulley attachment portion 60, and can be attached and detached in a state where it is wound around the wire 40. The hoist 4 is not limited to a configuration having the pulley 41, and may be configured such that the end of the wire 40 is directly connected to a slider.

[0028] [Configuration of hoist support member] The hoist support member 5 is attached to the apex of the upper support member 12 of the support column 1 as shown in FIGS. As shown in FIG. 9, the hoist support member 5 is detachable from the upper support member 12, and can be separated into two members. The hoist support member 5 is composed of two members: a support rod 50 which is inserted into and removed from the upper support member 12, and a rotating support rod 51 which is inserted into and removed from the support rod 50.

[0029] As shown in FIG. 9, the support rod 50 has an angular insertion portion 501 with a square cross section at the bottom that is inserted into and removed from the upper support member 12, and a round insertion portion 502 with a circular cross section above the insertion portion 501. In addition, a fall prevention portion 503 is provided between the angular insertion portion 501 and the round insertion portion 502, and when the angular insertion portion 501 is inserted into the upper support member 12, the fall prevention portion 503 is placed on the opening edge 120 of the upper support member 12, so that the support rod 50 can be held at the apex of the upper support member 12. The angular insertion part 501 is of a size such that its outer circumference does not wobble against the inner circumference of the upper support member 12 and can be easily inserted, making it easy to insert and remove, and also disabling rotation about an axis relative to the upper support member 12 when inserted. The round insertion portion 502 is inserted into the inner periphery of a round inserted portion 510 (described later) of the rotation support rod 51, and supports the round inserted portion 510 so as to be rotatable about its axis.

[0030] As shown in FIG. 9, the rotation support rod 51 is made up of the aforementioned round inserted portion 510 and a hoist hanging portion 511 fixed to the upper end of the round inserted portion 510. The round inserted portion 510 is sized so that its inner periphery fits snugly into the outer periphery of the round inserting portion 502, and can be freely rotated about its axis and can be freely inserted and removed. The hoist hanging part 511 is composed of a horizontal rod 5110 having one end fixed to the upper end of the round insertion part 510, and a vertical rod 5111 fixed to the other end. A pulley 52 is fixed to the horizontal rod 5110, and a rope 520 (see Figure 15) is wound around this pulley 52 so that various tools, parts, and the hoist 4 can be lifted to the upper floor using the pulley 52 and rope 520. The vertical rod 5111 is provided with a hoist attachment portion 53 for hooking the hook 43 of the hoist 4 and a wire side hook portion 54 for hooking the hook 401 of the wire 40 . The hoist mounting portion 53 is fixed to the lower end side of the vertical rod 5111, and is capable of suspending the hoist 4 when the hook 43 of the hoist 4 is hooked thereon. The wire-side hook portion 54 is provided on the surface of the vertical rod 5111 facing the round inserted portion 510 and protrudes in the direction of the round inserted portion 510 . As shown in Figure 3, the hoist mounting portion 53 and the wire side hook portion 54 are positioned so that when the hook 43 of the hoist 4 and the hook 401 of the wire 40 are hooked to the respective hook portions 53, 54, the pulley 41 is positioned directly above the pulley mounting portion 60 of the frame rod 620 on the slider 6. The extent to which the wire-side hooking portion 54 protrudes is such that when the hook 401 of the wire 40 is hooked, the hook 401 can be hooked so that the wire 40 does not interfere with the hoist 4.

[0031] [Effect of hoist support members] Such a hoist support member 5 allows the rotating support rod 51 to rotate relative to the support rod 50, and as shown in Figure 10, the vertical rod 5111 can be changed from a position in front of the support pillar 1 to a position in the rear. When hanging the hoist 4 from the hoist support member 5, by facing the vertical rod 5111 forward (towards building B) as shown in Figures 10(a) and (b), the hoist mounting portion 53 and the wire side hook portion 54 are positioned on the building B side, making it easy to hang the hoist 4 from the building B side. In addition, after the hoist 4 is suspended, the rotating support rod 51 is rotated relative to the support rod 50 so that the vertical rod 5111 faces backward, whereby the pulley 41 is positioned directly above the pulley mounting portion 60 of the frame rod 620 on the slider 6, thereby enabling the installation work of the pulley 41 to be completed quickly. The hoist support member 5 may have any configuration as long as it is capable of suspending at least the hoist 4.

[0032] [Hoist assembly procedure] Next, the assembly procedure of the lifting machine A will be described with reference to the assembly procedure diagrams (1) to (11) shown in Figs.

[0033] The following first to fourth steps are a step of forming a part of the base portion 2, a step of installing the slider 6, and a step of erecting the support pillar 1. First step (FIG. 11(1)): The base tube 210 is placed on the ground with the support tube 20 facing forward, and the expansion body 211 is inserted into the opening of the base tube 210 from the left and right directions and secured with bolts. In the first step, when positioning the base pipe 210 and the amount of protrusion of the extension body 211 relative to the base pipe 210, an optimal location is selected depending on the distance to the building and the location where the load is to be lifted.

In the fifth step, the installation work of the hoist support member 5 is carried out from the third floor side of building B, and in order to make it easier to carry out the seventh step described below, which is also carried out from the building B side, the vertical rod 5111 side of the hoist support member 5 is faced forward (towards building B).

[0035] The sixth step below is a step for completing the base portion 2. Sixth step (FIG. 14 (6-1) (6-2)): The leg pipe 214 is inserted into the leg connecting pipe 213 to complete the base part 2. In the sixth step, the adjuster 204 of the leg tube 214 is rotated and adjusted to make the base portion 2 horizontal.

[0036] The seventh and eighth steps below are steps for attaching the hoist 4. Seventh step (Figure 15 (7)): With the vertical rod 5111 of the hoist support member 5 facing forward, wind the rope 520 around the pulley 52 of the hoist support member 5 from the third floor side of building B, lower one end of the rope on the rear side and connect it to the hook 43 of the hoist 4, and pull the other front end of the rope 520 downward to lift the hoist 4. In the seventh step, the hoist 4 may be pulled up with the hook 401 of the wire 40 hooked, for example, on the hook 43 of the hoist 4 . Step 8 (Figure 15 (8)): The rope 520 connected to the hook 43 of the raised hoist 4 is removed, and the hook 43 is hooked to the hoist mounting portion 53 of the hoist support member 5. Furthermore, the hook 401 of the wire 40 is hooked to the wire side hook portion 54 of the hoist support member 5, thereby attaching the hoist 4 to the hoist support member 5. In an eighth step, a power cable is connected to the hoist 4 (not shown).

[0037] The following ninth and tenth steps are steps for lowering the pulley 41. Ninth step (FIG. 16(9)): Rotate the hoist support member 5 away from the building B so that the vertical rod 5111 faces backward. Tenth step (FIG. 16(10)): By operating an operation switch (not shown) connected to the above-mentioned power cable, the wire 40 is let out from the hoist 4 to lower the pulley 41. The pulley 41 is lowered to a position where the pulley 41 can be attached to the pulley attachment portion 60 provided on the slider 6.

[0038] The following eleventh step is a step of attaching the pulley 41 to the pulley attachment portion 60 provided on the slider 6. Step 11 (FIG. 17(11)): As shown in FIG. 8(c), the pulley mounting portion 60 is rotated upward, and the pulley support body 42 supporting the lowered pulley 41 is fitted into the frame rod 620, and the pulley mounting portion 60 is rotated downward, thereby attaching the pulley 41 to the slider 6.

[0039] By carrying out the above-mentioned first to eleventh steps in order, the lifting machine A as shown in FIG. 18 can be assembled.

[0040] [Effect of the lifting machine] The hoist A having the above-described configuration has a simple structure and can be quickly assembled and disassembled, thereby shortening the setup time and enabling efficient transportation and storage when disassembled.
