Description

modular elevator

[0001] The present invention relates to elevator installation technology, and more particularly to modular elevators.

[0002] The conventional elevator construction method involved assembling and installing each component that forms the elevator on-site after the steel frame of the building was installed.

[0003] Accordingly, elevator installation on-site takes a significant amount of time, extending the installation period. Furthermore, the risk of safety accidents due to working at heights during elevator installation increases, leading to increased on-site operating costs and a longer installation period.

[0004] In addition, due to the special nature of elevator installation, elevator installation work on site is mainly carried out vertically, and since vertical work cannot be carried out simultaneously in the up and down directions, the construction schedule may be delayed.

[0005] Modular elevators are being developed to solve this problem, but modular elevators have the problem that noise and vibration may occur due to misalignment of the rails, and alignment of the rails is difficult.

[0006] The present invention provides a modular elevator capable of pressurizing and joining both sides of rails located at the boundary of adjacent elevator modules with fish plates.

[0007] The present invention provides a modular elevator capable of pressurizing and connecting the back surface of a rail located at the boundary of adjacent elevator modules with a rail bracket.

[0008] A modular elevator according to one embodiment of the present invention comprises a plurality of elevator modules that are stackably connected and each include a rail portion, and a rail adjustment structure that is connected between the rail portions of adjacent elevator modules, wherein the rail adjustment structure

[0009] It includes a fish plate connected to one side and the other side with the adjacent rail section as the center.

[0010] In addition, in the modular elevator, the rail portion includes adjacent first rail portions and second rail portions, the fish plate includes a first fish plate and a second fish plate, the first fish plate can be coupled to one side of the boundary between the first rail portion and the second rail portion, and the second fish plate can be coupled to the other side of the boundary between the first rail portion and the second rail portion.

[0011] In addition, in the modular elevator, the rail adjustment structure further includes a fixing member, and a fixing member insertion hole for coupling the fixing member may be formed in the lower part of the first rail part and the upper part of the second rail part, which are the boundary parts between the first rail part and the second rail part, respectively.

[0012] In addition, in the modular elevator, the first rail portion includes a first rail and a first rail plate coupled to a back surface of the first rail, the second rail portion includes a second rail and a second rail plate coupled to a back surface of the second rail, and a first fixing member insertion hole for inserting a first fixing member of the fixing member may be formed in each of the first rail plate and the second rail plate, and a second fixing member insertion hole for inserting a second fixing member of the fixing member may be formed in each of the first rail and the second rail.

[0013] In addition, in the modular elevator, the first fish plate and the second fish plate are each formed with a first fish joint hole corresponding to the first fixing member insertion hole,

[0014] A second fish joint hole corresponding to the second fixing member insertion hole may be formed in each of the first fish plate and the second fish plate.

[0015] Additionally, in the modular elevator, the rail adjustment structure may further include a rail bracket that is respectively connected to the back surface of the adjacent rail portion and connected to the elevator frame.

[0016] Additionally, in the modular elevator, the rail bracket may include a frame coupling portion coupled to the elevator frame, a rail coupling portion coupled to the rear surface of the adjacent rail portion, and a connecting portion connecting the frame coupling portion and the rail coupling portion.

[0017] Additionally, in the modular elevator, the rail coupling portion may be formed with a rail coupling hole for coupling with the fish plate and the rail portion, and the rail coupling hole may be formed to face the rail portion.

[0018] Additionally, in the modular elevator, the rail joining hole is a slit extending in the stacking direction of the rail portion, and the rail joining hole can be formed to face the rail portion.

[0019] Additionally, in the modular elevator, the width of the rail joint is formed narrower than the width of the frame joint, and the connecting portion can be arranged to be inclined to connect the rail joint and the frame joint having different widths.

[0020] In addition, in the modular elevator, the frame joint portion may have a frame joint hole formed in order to be joined to the elevator frame, and the frame joint portion may be formed in a structure in which one end is horizontal and the other end is bent and extended at a certain angle.

[0021] According to the present invention, in a modular elevator, the alignment of rails located at the boundary of adjacent elevator modules in the left / right and front / back directions can be simply and conveniently adjusted.

[0022] According to the present invention, in a modular elevator, noise and vibration caused by the operation of an elevator car can be minimized by adjusting the alignment of the rails.

[0045] That is, the rail adjustment structure (1200) can adjust the alignment error of the rail portion (1110) by being pressurized and coupled to the rail portion (1110) located at the boundary of a plurality of elevator modules (1100).

[0046]

[0047] Hereinafter, the technical configuration, detailed shape, and organic joint structure of the rail adjustment structure will be described in more detail with reference to FIGS. 2 to 5.

[0048]

[0049] FIG. 2 is a schematic diagram of a rail adjustment structure in the modular elevator illustrated in FIG. 1, and FIG. 3 is a schematic exploded diagram of a rail adjustment structure in the modular elevator illustrated in FIG. 2.

[0050] As described above, the modular elevator (1000, see FIG. 1) comprises a plurality of elevator modules. FIGS. 2 and 3 illustrate the boundaries of two adjacent elevator modules as examples.

[0051] In this specification, the first elevator module (1100a) is described as being positioned above the second elevator module (1100b). The modular elevator (1000) includes adjacent first elevator modules (1100a) and second elevator modules (1100b). The first elevator module (1100a) is coupled to the second elevator module (1200b) so as to be stacked on top of each other.

[0052] The first elevator module (1100a) includes a first rail portion (1110a), and the second elevator module (1100b) includes a second rail portion (1110b).

[0053] The first rail portion (1110a) may include a first rail (1110a1) and a first rail plate (1110a2), and the second rail portion (1110b) may include a second rail (1110b1) and a second rail plate (1110b2).

[0054] The first rail portion (1110a) may include a first rail (1110a1) protruding forward and a first rail plate (1110a2) coupled to the back surface of the first rail.

[0055] The second rail portion (1110b) may include a second rail (1110b1) protruding forward and a second rail plate (1110b2) coupled to the back surface of the second rail (1110b1).

[0057] The cross-sections of the first rail portion (1110a) and the second rail portion (1110b) may be formed in an overall shape of "one end being horizontally wide and narrowing from the center to the other end." Alternatively, the first rail portion (1110a) and the second rail portion (1110b) may have a "structure in which one end is horizontally wide and gradually narrows from the center to the other end." Alternatively, "a shape in which one part is wide like a horizontal line and narrows from the center to the other end" may be applied to the first rail portion (1110a) and the second rail portion (1110b). For example, the cross-sections of the first rail portion (1110a) and the second rail portion (1110b) may be formed in an overall shape of "ㅗ."

[0058] The rail adjustment structure (1200) is configured to combine the boundary between the first rail portion (1110a) and the second rail portion (1110b) to adjust the alignment error between the first rail portion (1110a) and the second rail portion (1110b).

[0059] For this purpose, the rail adjustment structure (1200) can be coupled to the lower part of the first rail part (1110a) and the upper part of the second rail part (1110b).

[0060] More specifically, fixing member insertion holes (1111a1, 1111a2, 1111b1, 1111b2) may be formed at the lower portion of the first rail portion (1110a), which is the boundary between the first rail portion (1110a) and the second rail portion (1110b), and at the upper portion of the second rail portion (1110b), respectively.

[0061] The fixed member insertion holes (1111a1, 1111a2, 1111b1, 1111b2) are described in more detail through the organic joint structure of the rail adjustment structure (1200) described later.

[0062] The rail adjustment structure (1200) includes a fish plate (1210) and a rail bracket (1220).

[0063] The fish plate (1210) is for adjusting the left / right direction (W, see FIG. 4) alignment error of the first rail section (1110a) and the second rail section (1110b).

[0064] For this purpose, the fish plate (1210) is joined to both sides of the boundary between the first rail portion (1110a) and the second rail portion (1110b).

[0065] The fish plate (1210) may be formed as an integral structure that is joined to both sides of the boundary between the first rail portion (1110a) and the second rail portion (1110b).

[0066] The fish plate (1210) may include a first fish plate (1210a) and a second fish plate (1210b).

[0067] The first fish plate (1210a) can be coupled to one side of the boundary between the first rail portion (1110a) and the second rail portion (1110b), and the second fish plate (1210b) can be coupled to the other side of the boundary between the first rail portion (1110a) and the second rail portion (1110b).

[0068] The first fish plate (1210a) and the second fish plate (1210b) may be symmetrical to each other or may have the same size and shape.

[0069] The shape of the fish plate (1210) is described based on the first fish plate (1210a).

[0070] The first fish plate (1210a) may have an overall rectangular shape in consideration of structural stability and ease of assembly.

[0071] A first fish joint hole (1211a) and a second fish joint hole (1212a) may be formed in the first fish plate (1210a) to be coupled to the first rail portion (1110a) and the second rail portion (1110b).

[0072] The first fish joint hole (1211a) and the second fish joint hole (1212a) can be formed to penetrate the first fish plate (1210a).

[0073] The first fish joint hole (1211a) may be formed on the first surface (1210a') of the first fish plate (1210a), and the second fish joint hole (1212a) may be formed on the second surface (1210a") of the first fish plate (1210a).

[0074] The first side (1210a') and the second side (1210a") can be arranged in orthogonal directions.

[0075] Based on the direction in which the first fish plate (1210a) is coupled to the first rail portion (1110a) and the second rail portion (1110b), the first fish coupling hole (1211a) can be formed in the front direction (Y) of the first fish plate (1210a).

[0076] The second fish joint (1212a) can be formed in the lateral direction (Z) of the first fish plate (1210a).

[0077] The fixed member (1230) includes a first fixed member (1231) corresponding to the first fish joint hole (1211a) and a second fixed member (1232) corresponding to the second fish joint hole (1212a).

[0078] The first fixing member (1231) and the second fixing member (1232) may each be formed of a pair of bolts and nuts.

[0079] The first fish plate (1210a) can be fixed to the side and back surfaces of the first rail portion (1110a) and the second rail portion (1110b), respectively, by inserting the first fixing member (1231) and the second fixing member (1232) into the first fish joint hole (1211a) and the second fish joint hole (1212a).

[0080] The second fish plate (1210b) is formed with a first fish joint hole (1211b) and a second fish joint hole (1212b) in the same manner as the first fish plate (1210a) described above.

[0081] The first fish joint hole (1211b) and the second fish joint hole (1212b) can be formed to penetrate the second fish plate (1210b).

[0082] Next, the rail bracket (1220) is for connecting and supporting the rail portion (1110) to the elevator frame (1112).

[0083] The rail bracket (1220) has the function of adjusting the alignment error in the front-rear direction D (see FIG. 5) between the first rail (1110a) and the second rail (1110b). This helps achieve structural alignment with the rail bracket (1220). To this end, the rail bracket (1220) is coupled to the back surface of the boundary between the first rail portion (1110a) and the second rail portion (1110b).

[0084] That is, the rail bracket (1220) can be respectively coupled to the rail plates (1110a2, 1110b2) of the first rail portion (1110a) and the second rail portion (1110b).

[0085] The rail bracket (1220) may include a frame joint (1221), a rail joint (1222), and a connecting portion (1223).

[0086] The frame joint (1221) is for joining to the elevator frame (1112).

[0087] The rail joint (1222) is intended to be joined to the back surface of the rail portion (1110a, 1110b).

[0088] The connecting portion (1223) is for connecting the frame connecting portion (1221) and the rail connecting portion (1222).

[0089] The frame joint portion (1221), rail joint portion (1222) and connecting portion (1223) of the rail bracket (1220) can be formed integrally.

[0090] The rail joint portion (1222) and the connecting portion (1223) of the rail bracket (1220) are formed integrally, and the frame joint portion (1221) can be connected to the connecting portion (1223).

[0091] The frame joint (1221) may be formed as a structure in which one end is horizontal and the other end is bent and extended at a certain angle. For example, the frame joint (1221) may have an overall "L" shape. Accordingly, by means of the frame joint (1221), the connection part (1223) and the elevator frame can be joined with high structural safety and durability.

[0092] A first frame joining hole (1221a) for joining to an elevator frame (1112) may be formed in the frame joining part (1221), and a second joining hole (not shown) for joining to a connecting part (1223) may be formed in the frame joining part (1221).

[0093] The first frame joining hole (1221a) is formed on the first frame surface (1221') of the frame joining portion (1221), and the second frame joining hole is formed on the second frame surface (1221") of the frame joining portion (1221). The first frame surface (1221') and the second frame surface (1221") can be arranged in an orthogonal direction.

[0094] The rail joint (1222) can be joined to the back surfaces of the first rail portion (1110a) and the second rail portion (1110b).

[0095] That is, the rail joint (1222) can be joined to the back surface of the boundary between the first rail portion (1110a) and the second rail portion (1110b).

[0096] The rail joint (1222) can be formed in a plate shape so as to be joined to the back surface of the boundary between the rail plates (1110a2, 1110b2) of the first rail portion (1110a) and the second rail portion (1110b).

[0097] That is, the back surface of the boundary between the first rail portion (1110a) and the second rail portion (1110b) is connected to a plate-shaped rail connecting portion (1222), so that the front / rear alignment step (D, see FIG. 5) of the rail portion can be adjusted.

[0098] A rail joining hole (1222a) may be formed in the rail joining portion (1222) so as to face the boundary between the first rail portion (1110a) and the second rail portion (1110b).

[0099] The rail joining hole (1222a) can be formed as a slit extending in the stacking direction of the rail portions (1110a, 1110b).

[0100] The rail joining hole (1222a) manufactured in the form of a slit enables precise positioning and a quick joining process when joining the rail portion (1110a), the fish plate (1110b), and the rail bracket (1220), thereby saving time and effort in the entire assembly process.

[0101] The connecting portion (1223) is for connecting the frame connecting portion (1221) and the rail connecting portion (1222).

[0102] In addition, in order to more stably support the load of the rail portion (1110a, 1110b), the width (Z-direction length) of the rail joint portion (1222) may be formed narrower than the width (Z-direction length) of the frame joint portion (1221).

[0103] The connecting portion (1223) can be arranged to be inclined to connect the rail connecting portion (1222) and the frame connecting portion (1221) having different widths.

[0104] Meanwhile, the fixing member insertion holes (1111a1, 1111a2, 1111b1, 1111b2) formed in the first rail portion (1110a) and the second rail portion (1110b) include the first fixing member insertion holes (1111a1, 1111b1) and the second fixing member insertion holes (1111a2, 1111b2).

[0105] A first fixing member insertion hole (1111a1, 1111b1) for inserting a first fixing member (1231) may be formed in each of the first rail plate (1110a2) and the second rail plate (1110b2).

[0106] Second fixing member insertion holes (1111a2, 1111b2) for inserting a second fixing member (1232) may be formed in the first rail (1110a1) and the second rail (1110b1), respectively.

[0107] The first fixing member insertion holes (1111a1, 1111b1) are formed to correspond to the first fish joint holes (1211a, 1211b) and the rail joint holes (1222a), and the second fixing member insertion holes (1111a2, 1111b2) are formed to correspond to the second fish joint holes (1212a, 1212b).

[0110] And the first fixing member (1231) is inserted into the first fish joint holes (1211a, 1211b) of the first and second fish plates (1210a, 1210b), the fixing member insertion holes (1111a1, 1111b1) of the first rail part (1110a) and the second rail part (1110b), and the joint hole (1222a) of the rail joint part (1222), and is fixed to the rail bracket (1220) by joining them in the front / rear direction (Y).

[0111] In addition, the second fish joint holes (1212a, 1212b) of the first and second fish plates (1210a, 1210b) are aligned and positioned along the same axis in the second fixing member insertion holes (1111a2, 1111b2) of the first and second rail sections (1110a, 1110b).
