Description

Modular elevator

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

[0002] Conventional elevator construction methods have involved assembling and installing the elevator components on-site after the building's steel frame has been completed.

[0003] Consequently, installing elevators on-site takes a significant amount of time, which can prolong the construction period. Furthermore, the high incidence of safety accidents associated with working at heights during installation increases on-site operating costs, which may also lead to a longer installation duration.

[0004] In addition, due to the specialized nature of elevator installation, on-site work is primarily carried out vertically; since vertical work makes it impossible to perform installations simultaneously in the up and down directions, the construction schedule may be delayed.

[0005] Modular elevators are being developed to address this issue, but they have the problem that pit ladders, pit screens, or pit partitions must be installed in the pit area separately from the installation of the modular elevator, which requires additional installation time and reduces the efficiency of the modular elevator installation work.

[0006] The objective of the present invention is to provide a modular elevator that reduces elevator installation time and improves the efficiency of installation work. In particular, the invention provides a modular elevator that improves the efficiency of elevator installation work by reducing the installation time of pit ladders, pit screens, or pit partitions.

[0007] Another objective of the present invention is to provide a modular elevator that improves the convenience of installation work for pit ladders, pit screens, or pit partitions within the elevator shaft.

[0074] [Description of Modular Elevator Configuration]

[0075] Referring to FIGS. 1 and 2, the modular elevator (10) according to the present embodiment may include a pit ladder (100), a pit screen (200), and a pit partition (300). The pit ladder (100) may be coupled to the pit module (22) of the modular elevator (10). Additionally, the pit screen (200) may also be coupled to the pit module (22). Furthermore, the pit partition (300) may also be coupled to the pit module (22). The pit ladder (100), the pit screen (200), or the pit partition (300) may each be coupled to the pit module (22) by a bolt / nut fastening method.

[0076] Accordingly, there is no need to perform separate anchor formation work in the pit area for the installation of the pit ladder (100), pit screen (200), or pit partition (300). Through this, the elevator installation time can be shortened, and the efficiency of the elevator installation work can be improved.

[0077] The pit ladder (100), pit screen (200), or pit partition (300) can each be formed from a material selected from the group consisting of general structural carbon steel, general structural rolled steel, hot-rolled steel, high-strength steel alloy, and mixtures thereof. Through this, the pit ladder (100), pit screen (200), or pit partition (300) can secure sufficient strength to remain sturdy even under stress that may occur during elevator use, thereby improving the efficiency of the installation work for the pit ladder (100), pit screen (200), or pit partition (300) with minimal changes to the pit area.

[0078] The pit ladder (100), pit screen (200), or pit partition (300) can each be galvanized. Through this, the pit ladder (100), pit screen (200), or pit partition (300) can maintain their strength without corroding even under environmental stresses such as contamination or flooding that may occur in the pit area, thereby improving the efficiency of the installation work for the pit ladder (100), pit screen (200), or pit partition (300) with minimal changes to the pit area.

[0079] FIG. 3 is a perspective view showing the front of a pit ladder according to the present embodiment, and FIG. 4 is a perspective view showing the rear of a pit ladder according to the present embodiment.

[0080] Referring to FIGS. 2 to 4, the pit ladder (100) according to the present embodiment may be coupled to a pit module (22) among a plurality of elevator modules (20). The pit ladder (100) may serve as a device that allows a worker to safely move to the pit area during elevator maintenance. The pit ladder (100) may extend longitudinally to a position above the top of the pit module (22). Through this, a standardized work environment is provided, and the heights of the pit module (22) and related components are identical or harmonized, allowing the worker to predict the space and structure required during maintenance work in advance, thereby reducing work time and maintenance costs.

[0081] In addition, compatibility is improved; by designing for the same height, various modules can be made compatible with each other during parts replacement and upgrade work for maintenance, thereby providing cost efficiency in the long term. Furthermore, design repetition can be minimized; since the height of the pit ladder (100) is linked to the pit module (22), consistent specifications can be applied during the design phase, thereby reducing unnecessary repetitive work in the design and production processes. Additionally, the benefits of modular production can be maximized; parts with the same height standard are suitable for mass production and provide manufacturing cost reduction effects, thereby strengthening product competitiveness.

[0082] The pit ladder (100) may include a ladder body (110) and a plurality of ladder brackets (120). The pit ladder (100) can be connected to the pit module (22) by means of a plurality of ladder brackets (120) that are respectively connected to the ladder body (110) and the pit module (22). Through this, the installation of the pit ladder (100) can be easily achieved simply by connecting the plurality of ladder brackets (120) to the pit module (22), and work inside the elevator shaft can also be easily performed when necessary.

[0083] Through this, at the elevator shaft installation site, the installation of the pit ladder (100) suitable for the site structure is carried out by adjusting the connection position through the ladder bracket (120), thereby ensuring the stability of the pit ladder (100) installation work and uniformity of the installation quality.

[0084] The ladder body (110) may include a pair of ladder supports (111), a plurality of ladder steps (112), and a plurality of support holes (113). A plurality of ladder steps (112) arranged parallel to each other may each be supported by a pair of ladder supports (111).

[0085] A pair of ladder supports (111) can each be extended parallel to the longitudinal direction. This improves workability during the production of the pit ladder (100). Additionally, a pair of ladder supports (111) can each be extended at a predetermined angle relative to the longitudinal direction. This improves the convenience of use for a worker moving with the pit ladder (100).

[0086] Multiple ladder steps (112) may each be extended perpendicular to the longitudinal direction. Multiple ladder steps (112) may extend from one of a pair of ladder supports (111) to the other. This ensures the safety of a moving worker using the pit ladder (100). Each of the multiple ladder steps (112) may be joined to a pair of ladder supports (111) by a welding method. Additionally, at least one of the multiple ladder steps (112) may be joined to a pair of ladder supports (111) by a method other than welding.

[0087] A plurality of support holes (113) may be formed in each of a pair of ladder supports (111). The plurality of support holes (113) may be formed at positions that match the location of at least one first ladder bracket hole (123), which will be described later and is formed in each of a plurality of ladder brackets (120). A fastening bolt (not shown) may pass through each of the plurality of support holes (113) and at least one ladder bracket hole (123) formed at mutually matching positions. Subsequently, a fastening nut (not shown) may be fastened to the fastening bolt. Accordingly, a plurality of ladder brackets (120) may be coupled to each of a pair of ladder supports (111).

[0088] A plurality of ladder brackets (120) can be respectively connected to the ladder body (110) and the pit module (22). As the plurality of ladder brackets (120) are respectively connected to the ladder body (110) and the pit module (22), the pit ladder (100) can be connected to the pit module (22). Each of the plurality of ladder brackets (120) may include a plurality of ladder bracket plates (121), a plurality of ladder bracket bending portions (122), a plurality of first ladder bracket holes (123), and a plurality of second ladder bracket holes (124). Through this, at the elevator shaft installation site, the installation of the pit ladder (100) suitable for the site structure can be performed simply by adjusting the connection position through the ladder brackets (120), thereby ensuring the stability of the pit ladder (100) installation work and uniformity of the installation quality.

[0089] A plurality of ladder bracket plates (121) can each be coupled to the ladder body (110). That is, a plurality of ladder bracket plates (121) can each be coupled to a pair of ladder supports (111). A plurality of first ladder bracket holes (123) can each be formed in at least one of the plurality of ladder bracket plates (121). That is, a plurality of first ladder bracket holes (123) can each be formed in at least one ladder bracket plate (121). The location of the at least one first ladder bracket hole (123) formed in each of the plurality of ladder bracket plates (121) can each be matched with the location of a plurality of support holes (113).

[0090] A plurality of first ladder bracket holes (123) may be formed in an elliptical shape. Accordingly, when a plurality of ladder brackets (120) are each coupled to the ladder body (110), the coupling position of the plurality of ladder brackets (120) to the ladder body (110) can be adjusted by adjusting the position of each of the plurality of fastening bolts penetrating through the plurality of elliptical second ladder bracket holes (123). Additionally, at least one of the plurality of first ladder bracket holes (123) may be formed in a shape other than an elliptical shape.

[0091] A plurality of ladder bracket bending portions (122) can be bent from a plurality of ladder bracket plates (121). A plurality of ladder bracket bending portions (122) can be connected to a pit module (22). A plurality of ladder bracket bending portions (122) can be bent and extended from each other side opposite to each of the two sides of a plurality of ladder bracket plates (121) that are connected to a pair of ladder supports (111).

[0092] A plurality of second ladder bracket holes (124) may each be formed in at least one of a plurality of ladder bracket bending portions (122). That is, a plurality of second ladder bracket holes (124) may each be formed in at least one of a single ladder bracket bending portion (122). A fastening bolt (not shown) may pass through each of the plurality of second ladder bracket holes (124) and the fastening holes (not shown) formed in the pit module (22). Subsequently, a fastening nut (not shown) may be fastened to the fastening bolt. Accordingly, a plurality of ladder brackets (120) may each be coupled to the pit module (22).

[0093] A plurality of second ladder bracket holes (124) may be formed in an elliptical shape. Accordingly, when a plurality of ladder brackets (120) are each coupled to a pit module (22), the coupling position of the plurality of ladder brackets (120) to the pit module (22) can be adjusted by adjusting the position of each of the plurality of fastening bolts penetrating through each of the elliptical second ladder bracket holes (124). Additionally, at least one of the plurality of second ladder bracket holes (124) may be formed in a shape other than an elliptical shape.

[0094] The present invention is not limited to what is shown or described above. What is shown or described above is merely an example.

[0095] FIG. 5 is a perspective view showing the front of a pit screen according to the present embodiment, FIG. 6 is a perspective view showing the rear of a pit screen according to the present embodiment, and FIG. 7 is a perspective view showing the combined state of a pit screen according to the present embodiment.

[0096] Referring to FIGS. 2, 5 to 7, the pit screen (200) according to the present embodiment can be coupled to the pit module (22). The pit screen (200) can serve as a device that ensures work stability by separating the car-side area and the weight-side area, thereby preventing a worker from unintentionally moving to another area during elevator maintenance. The pit screen (200) can be extended longitudinally to a position above the top of the pit module (22). Through this, a standardized work environment is provided, and the heights of the pit module (22) and related components are the same or harmonized, allowing the worker to predict the space and structure required during maintenance work in advance, thereby reducing work time and maintenance costs.

[0097] In addition, compatibility is improved; by designing with the same height, various modules can be made compatible with each other during parts replacement and upgrade work for maintenance, thereby providing cost efficiency in the long term. Furthermore, design repetition can be minimized; since the height of the pit screen (200) is linked to the pit module (22), consistent specifications can be applied during the design phase, thereby reducing unnecessary repetitive work in the design and production processes. Additionally, the benefits of modular production can be maximized; parts with the same height standard are suitable for mass production and provide manufacturing cost reduction effects, thereby strengthening product competitiveness.

[0098] The pit screen (200) may include a screen body (210) and a plurality of screen brackets (220). The pit screen (200) may be connected to the pit module (22) by the plurality of screen brackets (220), which are respectively connected to the screen body (210) and the pit module (22). Through this, the installation of the pit screen (200) can be easily achieved simply by connecting the screen brackets (220) to the pit module (22), and work inside the elevator shaft can also be easily performed if necessary.

[0099] The screen body (210) may be formed in a pair of flat shapes. The screen body (210) may include a first screen (211), a second screen (212), and a plurality of screen holes (213). The first screen (211) and the second screen (212) may be arranged to face each other in a circumferential direction. The first screen (211) and the second screen (212) may be arranged to be spaced apart from each other by a predetermined distance. Accordingly, a space of a predetermined distance may be formed between the first screen (211) and the second screen (212). A car-side rail (41) may be located in the space spaced apart by a predetermined distance between the first screen (211) and the second screen (212).

[0100] By doing so, the space between the first screen (211) and the second screen (212) can be designed with a predetermined spacing to serve as a guideline for the installation of the car-side rail (41). The installation location of the car-side rail (41) becomes clear, eliminating the need for additional manual labor, and can shorten work time and improve precision. Additionally, the worker can work freely in the space between the car-side rail (41) and the pit screen (200), thereby increasing work efficiency even in narrow elevator shafts. Furthermore, since the car-side rail (41) is installed while the pit screen (200) is fixed, the vertical alignment error of the car-side rail (41) is minimized, ensuring uniform installation quality, and stable operation of the car-side rail (41) can be expected during subsequent maintenance.

[0101] A plurality of screen holes (213) may be formed in the first screen (211) and the second screen (212), respectively.

A fastening bolt (not shown) may pass through each of the plurality of screen holes (213) and the at least one first screen bracket hole (223) formed at positions that match each other. Subsequently, a fastening nut (not shown) may be fastened to the fastening bolt. Accordingly, a plurality of screen brackets (220) may be coupled to the first screen (211) and the second screen (212), respectively.

[0102] A plurality of screen holes (213) may be formed in an elliptical shape. Accordingly, when a plurality of screen brackets (220) are each coupled to the screen body (210), the coupling position of the plurality of screen brackets (220) to the screen body (210) can be adjusted by adjusting the position of each of the plurality of fastening bolts penetrating through each of the elliptical screen holes (213). Additionally, at least one of the plurality of screen holes (213) may be formed in a shape other than elliptical.

[0103] A plurality of screen brackets (220) can be respectively connected to the screen body (210) and the pit module (22). As a plurality of screen brackets (220) are respectively connected to the screen body (210) and the pit module (22), the pit screen (200) can be connected to the pit module (22). Specifically, a plurality of screen brackets (220) can each be connected to a plurality of weight-side rails (42).

[0104] Each of the multiple screen brackets (220) may include a plurality of screen bracket plates (221), a plurality of screen bracket bending portions (222), a plurality of first screen bracket holes (223), and a plurality of second screen bracket holes (224). Through this, at the elevator shaft installation site, the installation of the pit screen (200) suitable for the site structure can be carried out by adjusting the connection position through the screen brackets (220), thereby ensuring the stability of the pit screen (200) installation work and uniformity of the installation quality.

[0105] A plurality of screen bracket plates (221) can each be coupled to the screen body (210). That is, a plurality of screen bracket plates (221) can each be coupled to the first screen (211) and the second screen (212). A plurality of first screen bracket holes (223) can each be formed in at least one of the plurality of screen bracket plates (221). That is, a plurality of first screen bracket holes (223) can each be formed in at least one screen bracket plate (221).

[0106] The position of at least one first screen bracket hole (223) formed in each of the plurality of screen bracket plates (221) can be matched with the position of each of the plurality of screen holes (213). Each of the plurality of first screen bracket holes (223) can be formed in a circular shape. Additionally, at least one of the plurality of first screen bracket holes (223) may be formed in a shape other than a circular shape.

[0107] A plurality of screen bracket bending portions (222) can be bent from each of the plurality of screen bracket plates (221). A plurality of screen bracket bending portions (222) can be connected to each pit module (22). A plurality of screen bracket bending portions (222) can be bent and extended from each of the respective sides of the plurality of screen bracket plates (221).

[0108] A plurality of second screen bracket holes (224) may each be formed in at least one of a plurality of screen bracket bending portions (222).

[0112] Referring to FIGS. 2 and FIGS. 8 through 10, the pit partition (300) according to the present embodiment can be coupled to a pit module. The pit partition (300) can serve as a device that ensures work stability by separating different car-side zones and preventing a worker from unintentionally moving to a different car-side zone during elevator maintenance. The pit partition (300) can be extended longitudinally to a position above the top of the pit module (22). This provides a standardized work environment, whereby the heights of the pit module (22) and related components are identical or harmonized, allowing the worker to predict the required space and structure in advance during maintenance work, thereby reducing work time and maintenance costs.

[0113] In addition, compatibility is improved. By designing with the same height, various modules can be made compatible with each other during parts replacement and upgrade work for maintenance, thereby providing cost efficiency in the long term. Furthermore, design repetition can be minimized. Since the height of the pit partition (300) is linked to the pit module (22), consistent specifications can be applied during the design phase, which reduces unnecessary repetitive work in the design and production processes. Additionally, the benefits of modular production can be maximized. Parts with the same height standard are suitable for mass production and provide manufacturing cost reduction effects, thereby strengthening product competitiveness.

[0140] The governor tension sheave (400) may be equipped with a tension sheave weight (430) formed to have a preset weight. The governor tension sheave (400) and the tension sheave weight (430) can be integrated and move together along the rail (40) in the longitudinal direction. Accordingly, the governor tension sheave (400) can transmit the preset gravity of the tension sheave weight (430) to the rope (70) to maintain a preset tension in the rope (70). Through this, the rope (70) moves in the longitudinal direction with a preset tension, and the overspeed of the elevator can be detected quickly.

[0141] FIG. 16 is a perspective view showing a tension sheave base according to another embodiment.

[0142] Referring to FIG. 1 and FIG. 11 to 16, a tension sheave base (410) according to another embodiment may be formed in a plate shape. The tension sheave base (410) may be formed from a material selected from the group consisting of general structural carbon steel, general structural rolled steel, hot rolled steel, high-strength steel alloy, and mixtures thereof.

[0143] The tension sheave base (410) may be galvanized. Through this, the tension sheave base (410) can maintain its strength without corrosion even under environmental stresses such as contamination and flooding that may occur in the pit area. The tension sheave base (410) may include a first tension sheave hinge (411), a second tension sheave hinge (412), a tension sheave fixing hole (413), at least one weight coupling hole (414), and at least one cover coupling hole (415).

Through this, the governor tension sheave (400) may freely rotate with respect to the tension sheave bracket (500) coupled to the rail (40), thereby transmitting the preset gravity of the tension sheave weight (430) to the rope (70) and generating a preset tension in the rope (70).

[0146] The tension sheave fixing hole (413) may be formed in the governor tension sheave (400). The tension sheave fixing hole (413) may be formed on one side in the radial direction of the tension sheave base (410). A fixing body (600), to be described later, may be inserted into the tension sheave fixing hole (413). The fixing body (600) may be inserted into the tension sheave fixing hole (413) and the bracket fixing hole (517) formed in the bracket base (510) of the tension sheave bracket (500), to be described later, respectively, and then fastened with a fastening nut (800). Accordingly, the rotation of the governor tension sheave (400) relative to the tension sheave bracket (500) may be restricted. Through this, damage to elevator parts, such as the governor tension sheave (400) installed in the elevator module (20), can be prevented during the transport of the elevator module (20).

The wheel hinge (423) may be rotatably connected to the first tension sheave hinge (411) of the tension sheave base (410) by the wheel connecting rod (424). Through this, the position of the governor tension sheave (400) can be stably maintained even when the rope (70) rotates.

[0151] The tension sheave wheel (420) can be formed from a material selected from the group consisting of general structural carbon steel, general structural rolled steel, hot-rolled steel, high-strength steel alloy, and mixtures thereof. Through this, the tension sheave wheel (420) can secure sufficient strength to firmly support the rope (70). The tension sheave wheel (420) can be galvanized.

[0153] The wheel recess (422) may be formed in the center of the outer surface of the wheel base (421). A rope (70) may be wound in the wheel recess (422). The wheel recess (422) may be formed with a predetermined width and a predetermined depth. Accordingly, the rope (70) can be stably wound without being separated from the wheel recess (422). Through this, the rope (70) moves in the longitudinal direction with a predetermined tension, and the overspeed of the elevator can be quickly detected.

[0154] The wheel hinge (423) can be formed in the center of the tension sheave wheel (420). That is, the wheel hinge (1230) can be located inside the wheel base (421). The wheel hinge (423) and the wheel base (421) can be connected to each other by a plurality of wheel supports (not shown). Preferably, four or more wheel supports can be formed.

[0155] The wheel connecting rod (424) can rotatably connect the wheel hinge (423) and the first tension sheave hinge (411) of the tension sheave base (410). Accordingly, the tension sheave wheel (420) can be rotatably connected to the tension sheave base (410). Through this, the position of the governor tension sheave (400) can be stably maintained even when the rope (70) rotates.

[0156] The present invention is not limited to what is shown or described above. What is shown or described above is merely an example.

[0157] A tension sheave weight (430) according to another embodiment may be coupled to a tension sheave base (410). The tension sheave weight (430) may be formed to have a preset weight. Accordingly, the tension sheave weight (430) may transmit a preset gravity to the rope (70) to maintain a preset tension in the rope (70). Through this, the rope (70) may move longitudinally with the preset tension, and the overspeed of the elevator may be detected quickly. The tension sheave weight (430) may include a first weight portion (431) and a second weight portion (432). Accordingly, a tension sheave base (410) may be positioned between the first weight portion (431) and the second weight portion (432). Through this, the tension sheave weight (430) can stably transfer the preset weight to the rope (70) without tilting.

[0158] The tension sheave weight (430) can be formed from a material selected from the group consisting of general structural carbon steel, general structural rolled steel, hot-rolled steel, high-strength steel alloy, and mixtures thereof. Through this, the tension sheave weight (430) can secure sufficient strength to support a preset weight. The tension sheave weight (430) can be galvanized. Through this, the tension sheave weight (430) can maintain its strength without corrosion even under environmental stresses such as contamination and flooding that may occur in the pit area.

[0159] The first weight section (431) may be located on one side of the tension sheave base (410). The first weight section (431) may include at least one weight plate (not shown). Accordingly, the weight of the first weight section (431) may be adjusted by adjusting the number of weight plates. Additionally, the weight of the first weight section (431) may be adjusted by adjusting the weight of each of the at least one weight plates.

[0160] The second weight section (432) may be located on the other side of the tension sheave base (410). The second weight section (432) may include at least one weight plate.

[0161] At least one first base coupling hole (not shown) may be formed in each of the first weight portion (431) and the second weight portion (432). The at least one first base coupling hole may be formed at a position that matches the position of at least one weight coupling hole (414) formed in the tension sheave base (410). After the first weight portion (431) and the second weight portion (432) are each positioned on both sides of the tension sheave base (410), at least one fastening bolt (700) may pass through the at least one weight coupling hole (414) and the at least one first base coupling hole formed at positions that match each other.

[0163] A tension sheave cover (440) according to another embodiment may be coupled to a tension sheave base (410). The tension sheave cover (440) can protect the rail (40) wound on the governor tension sheave (400) from external impact. This allows the rope (70) to move in the longitudinal direction with a preset tension, and enables the elevator to quickly detect whether it is overspeeding. The tension sheave cover (440) may include a cover plate portion (441) and a cover fold portion (442). Accordingly, the tension sheave cover (440) can protect the rope (70) from impacts applied from various external directions. The tension sheave cover (440) may be coupled to a tension sheave base (410) after the rail (40) is wound on a tension sheave wheel (420). Through this, the rail (40) can be easily wound onto the tension sheave wheel (420).

[0164] The cover plate portion (441) may be formed in a plate shape. One of the two sides of the cover plate portion (441) connected to the cover fold portion (442) may be formed in a square shape. The other of the two sides of the cover plate portion (441) may be formed in a circular shape following the shape of the wheelbase (421).

[0165] The cover bend portion (442) may extend in a direction perpendicular to the cover plate portion (441). For example, the cross-section of the tension sheave cover (440) may be formed in an "L" shape by the cover plate portion (441) and the cover bend portion (442). Also, as another example, the cross-section of the tension sheave cover (440) may be formed in a "C" shape by the cover plate portion (441) and a pair of cover bend portions (442).

A tension sheave base (410) may be coupled to the pit module (20) by welding. Through this, the tension sheave base (410) may be firmly coupled to the pit module (20). Additionally, the tension sheave base (410) may be coupled to the pit module (20) by a method other than welding, such as a bolt fastening method or a rivet fastening method. Through this, the tension sheave base (410) may be easily detachably coupled to the pit module (20). In addition, the connection position of the tension sheave base (410) connected to the pit module (20) can be easily adjusted at the installation site.

[0168] The tension sheave bracket (500) may include a bracket base (510), a base connecting rod (520), and a switch bracket (530). The governor tension sheave (400) may be rotatably connected to the bracket base (510) by the base connecting rod (520).

[0169] FIG. 17 is a perspective view showing a bracket base according to the present embodiment.

[0170] Referring to FIG. 1, FIG. 11 to FIG. 15 and FIG. 17, a bracket base (510) according to another embodiment may be formed in a plate shape. The bracket base (510) may be formed from a material selected from the group consisting of general structural carbon steel, general structural rolled steel, hot-rolled steel, high-strength steel alloy, and mixtures thereof. Through this, the bracket base (510) can secure sufficient strength to firmly support the switch bracket (530), etc.

[0171] The bracket base (510) may be galvanized. Through this, the bracket base (510) can maintain its strength without corrosion even under environmental stresses such as contamination or flooding that may occur in the pit area. The bracket base (510) may include a bracket plate portion (511), a bracket bend portion (512), at least one first module coupling hole (513), at least one second module coupling hole (514), a bracket hinge (515), at least one switch bracket coupling hole (516), and a bracket fixing hole (517).

[0172] The bracket plate portion (511) may be formed in a plate shape. The bracket bend portion (512) may be extended in a direction perpendicular to the bracket plate portion (511). For example, the cross-section of the bracket base (510) may be formed in an "L" shape by the bracket plate portion (511) and the bracket bend portion (512).

At least one first module coupling hole (513) may be formed on one radial side of each bracket base (510). At least one first module coupling hole (513) may be formed in an elliptical shape. Accordingly, when the bracket base (510) is coupled to the pit module (22), the coupling position of the bracket base (510) can be adjusted by adjusting the position of each of the at least one fastening bolt (700) in the elliptical at least one first module coupling hole (513).

[0174] Additionally, at least one of the first module coupling holes (513) may be formed in a shape other than an ellipse, such as a circle. Also, the bracket base (510) may be joined to the pit module (22) by welding. Through this, the bracket base (510) can be firmly joined to the pit module (22).

[0175] At least one second module coupling hole (514) may be formed in each bracket base (510). At least one second module coupling hole (514) may be formed on one radial side of each bracket base (510). At least one second module coupling hole (514) may be formed in a circular shape. Accordingly, after the coupling position of the bracket base (510) is adjusted by adjusting the position of each of the at least one fastening bolt (700) fastened to at least one first module coupling hole (513), at least one fastening bolt (700) is fastened to each of the at least one second module coupling hole (514) to firmly fix the bracket base (510) to the pit module (22).

Accordingly, the governor tension sheave (400) may rotate with respect to the tension sheave bracket (500). Through this, the governor tension sheave (400) may freely rotate with respect to the tension sheave bracket (500) coupled to the rail (40), thereby transmitting the preset gravity of the tension sheave weight (430) to the rope (70) and generating a preset tension in the rope (70).

[0177] At least one switch bracket coupling hole (516) may be formed on the radial opposite side of the bracket base (510). At least one switch bracket coupling hole (516) may be formed at a position that matches the position of at least one first bracket base coupling hole (not shown) formed in the switch bracket (530) to be described later. At least one fastening bolt (700) may pass through each of the at least one switch bracket coupling hole (516) and at least one first bracket base coupling hole formed at the respective positions that match each other. Subsequently, at least one fastening nut (800) may be fastened to each of the at least one fastening bolt (700).

Accordingly, the rotation of the governor tension sheave (400) relative to the tension sheave bracket (500) may be restricted. Through this, damage to elevator parts, such as the governor tension sheave (400) installed in the elevator module (20), can be prevented during the transport of the elevator module (20).

[0180] According to another embodiment, the base connecting rod (520) can rotatably connect the second tension sheave hinge (412) provided on the tension sheave base (410) and the bracket hinge (515) of the bracket base (510). Accordingly, the governor tension sheave (400) can rotate with respect to the tension sheave bracket (500). Through this, the governor tension sheave (400) can freely rotate with respect to the tension sheave bracket (500) coupled to the rail (40), thereby transmitting the preset gravity of the tension sheave weight (430) to the rope (70) and generating a preset tension in the rope (70).

[0187] [Example of operation of a modular elevator according to another embodiment]

[0188] The operating effects of the modular elevator (10) according to the present invention are as follows.

[0189] FIG. 18 is a block diagram showing a method of installing a governor tension sheave according to another embodiment, and FIG. 19 is a front view showing a method of installing a governor tension sheave according to another embodiment.

[0190] Referring to FIGS. 1 and FIGS. 11 to 19, a modular elevator (10) according to another embodiment may include a fixed body coupling step (S100), a rope winding step (S200), and a fixed body separation step (S300). Before the installation of the pit module (22), the fixed body (600) may be coupled to the governor tension sheave (400) and the tension sheave bracket (500), respectively, thereby restricting the rotation of the governor tension sheave (400) relative to the tension sheave bracket (500). After the installation of the pit module (22), the fixed body (600) may be separated from the governor tension sheave (400) and the tension sheave bracket (500), respectively, thereby enabling the rotation of the governor tension sheave (400) relative to the tension sheave bracket (500).

[0191] Referring to FIG. 1 and FIG. 11 to FIG. 19(a), the fixed body coupling step (S100) may be a step of preventing rotation of the governor tension sheave (400) relative to the tension sheave bracket (500) by installing a fixed body (600) between a tension sheave bracket (500) coupled to a pit module (22) among elevator modules (20) and a governor tension sheave (400) rotatably coupled to the tension sheave bracket (500).

[0192] In the fixed body coupling step (S100), the fixed body (600) can be inserted into the tension sheave fixing hole (413) formed in the governor tension sheave (400) and the bracket fixing hole (517) formed in the tension sheave bracket (500), respectively, and then fastened with a fastening nut (800). After the fixed body coupling step (S100) is performed, the tension sheave bracket (500) can be coupled to the pit module (22). Through this, damage to the governor tension sheave (400) due to rotation relative to the tension sheave bracket (500) of the governor tension sheave (400) can be prevented while coupling the tension sheave bracket (500) to the pit module (22).

[0193] The present invention is not limited to what is shown or described above. What is shown or described above is merely an example.

[0194] Referring to FIGS. 1, FIGS. 11 to 18 and FIG. 19(b), the rope winding step (S200) may be a step of winding the rope (70) onto the governor tension sheave (400) after the installation of the pit module (22). That is, the rope winding step (S200) may be a step of winding the rope (70) onto a tension sheave wheel (420) rotatably coupled to the tension sheave base (410).

[0195] After the rope winding step (S200), the tension sheave cover (440) provided on the governor tension sheave (400) can be connected to the tension sheave base (410) provided on the governor tension sheave (400). Then, the fixing bolt separation step (S300) can be performed. Through this, the rope (70) can be easily connected to the tension sheave wheel (420).

[0196] The present invention is not limited to what is shown or described above. What is shown or described above is merely an example.

[0197] Referring to FIGS. 1, FIGS. 11 to 18 and FIG. 19(c), the fixed body separation step (S300) may be a step of separating the fixed body (600) so that the governor tension sheave (400) can rotate with respect to the tension sheave bracket (500). Accordingly, the governor tension sheave (400) can transmit the preset gravity of the tension sheave weight (430) to the rope (70) to maintain the preset tension in the rope (70). Through this, the rope (70) can move in the longitudinal direction with the preset tension, and the overspeed of the elevator can be quickly detected.

[0198] As such, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such modified or varied embodiments should be deemed to fall within the scope of the claims of the present invention.
