Abstract

In order to address the problems associated with conventional small cargo elevators, such as the requirement of a machine room on the rooftop or uppermost floor, which increases construction costs and imposes building height or structural constraints, and the fact that the entire facility is often over-designed despite the small cargo transport capacity, thereby burdening small buildings with auxiliary space outside the elevator shaft; the problem that existing small cargo elevators lack flexibility in door options, even though a selection of automatic, manual, vertical, or half-automatic door types is required depending on site conditions; and the inconvenience of maintenance access for workers within the machine room or narrow upper space, as well as the frequent risk of safety accidents occurring during repair and after-sales service where the small cargo elevator descends or sags due to small cargo due to the absence of an emergency stop device, the invention comprises a small cargo elevator shaft section (100), a small cargo car section (200), a small cargo car frame section (300), a small cargo hoisting unit (400), a small cargo drive motor section (500), and small cargo By configuring the hoisting wire rope section (600), the small cargo governor wire rope section (700), the small cargo counterweight section (800), the small cargo rail section (900), the guide beam contact pressure type cargo car elevator inspection lock section (900a), the small cargo position detection section (900b), the small cargo door section (900c), and the small cargo smart control section (900d), the hoisting machine and control panel are not installed together in a separate machine room like conventional elevators; instead, the hoisting machine, sheave, control device, small cargo governor, and inspection port are concentrated in the upper head-type H-beam section of the upper head section within the hoisting shaft, creating an upper head-type H-beam concentrated MRL (Machine Room Less) structure. This allows for a reduction in construction costs and installation area by 60% or less compared to conventional methods, and by configuring the small cargo hoisting machine section, the actual lifting and lowering power of the small cargo car section on the MRL (Machine Room Less) room section It forms a precision hoist suitable for small cargo weighing 300kg or less, andBy forming an upper head-type H-beam section at a height of 500mm from the lower horizontal frame for the MRL (Machine Room Less) room section and forming a small cargo hoisting mechanism on this upper head-type H-beam section, space can be reduced by less than 60% compared to existing systems. Furthermore, the configuration of a small cargo counterweight section reduces the load on the small cargo drive motor section by less than 40% compared to existing systems, reduces power consumption by less than 60%, improves ascent / descent stability by 80%, and reduces braking impact by less than 40%. Additionally, the configuration of a guide beam contact-pressure type cargo car elevator inspection lock mechanically prevents accidental ascent / descent of the small cargo car section during inspection. Unlike simple control signal blocking as in existing systems, this physically restricts the freedom of movement through an actual contact-pressure structure with the left and right car guide beams, thereby improving the safety of the inspector by 80%. Moreover, without the need for separate large locking equipment, the car frame or the bottom of the door Since it can be installed compactly in confined spaces, it is suitable for small MRL freight car elevators. With a 2-channel structure and multiple locations positioned on the upper left and right sides of the small freight car section, as well as on the lower left and right sides, it can reduce uneven load, twisting, and minute shaking of the small freight car section by less than 10% compared to conventional systems. Furthermore, since the start and release of inspection mode are linked to the small freight smart control unit, the inspector can easily engage and disengage the inspection lock state. With the configuration of the small freight smart control unit, "movement control" and "stopping safety" do not exist separately as in conventional systems; instead, operation control and safety control are analyzed simultaneously and immediately reflected within the same judgment system. As a result, the overall system responsiveness becomes 1.5 to 2 times faster than conventional systems, allowing for monitoring the current location of the small freight car, its speed, whether deceleration is normal, and the safety status of the doors.The purpose is to provide a control device and method for a guide beam contact pressure type MRL smart inspection lock type 300kg small cargo safety elevator that can control operation while performing complex analysis up to the point of approaching the end, improve the dedicated smart control effect tailored to the specific characteristics of small cargo by 80% compared to existing methods through the guide beam contact pressure type inspection lock control effect of the inspection drive control signal that responds when an inspector inspects the cargo car elevator or switches software, and shorten maintenance by 1.5 to 2 times compared to existing methods through a highly safe inspection environment.

Description

Technology Field

[0001] The present invention relates to a guide beam contact pressure type MRL smart inspection locking type safety elevator for 300kg small cargo, which is applied to school buildings, hospitals and medical facilities, small commercial buildings and restaurants, factories and manufacturing facilities, warehouses and logistics facilities, and residential logistics spaces. More specifically, it is installed in the upper head section of the elevator shaft within the building with a machine room-less MRL structure, and transports small cargo weighing 300kg or less between floors while loaded. During inspection, it temporarily blocks the vertical movement freedom of the small cargo car section by contacting a guide beam located on the guide rail with a 300kg·f force having horizontal linear motion, and after the inspection is completed, it is configured to return to its original state. Background Technology

[0003] Recently used small freight elevators require a machine room on the rooftop or at the top of the floor, which increases construction costs and results in building height restrictions or structural constraints.

[0004] In particular, it was inconvenient to apply to school buildings, hospital buildings, small commercial buildings, factories, warehouses, and residential logistics spaces.

[0005] In addition, although the cargo transport capacity is small, the entire facility is often over-designed, which poses a problem in small buildings where the auxiliary space outside the elevator shaft is burdensome. Also, depending on site conditions, it is necessary to select automatic doors, manual doors, vertical opening / closing types, or half automatic opening / closing types, but there is a problem with the lack of flexibility in door options in the case of existing small cargo elevators.

[0006] In addition, existing small cargo elevators use simple on / off control or low-level control, which causes significant problems such as floor stop errors, shaking, starting shock, and stopping shock. Furthermore, it is inconvenient for workers to access maintenance areas in the machine room or upper confined spaces, and because there is no emergency stop device, there is a frequent risk of safety accidents where the small cargo elevator descends or sags due to small cargo, injuring workers during repair and service operations.

Effects of the invention

[0029] As explained above, in the present invention

[0031] First, through the small cargo elevator shaft section, the hoisting machine and control panel are not installed together in a separate machine room like conventional elevators; instead, the hoisting machine, sheave, control device, small cargo governor, and inspection port are concentrated in the upper head-type H-beam section of the upper head section within the elevator shaft, creating an upper head-type H-beam concentrated MRL (Machine Room Less) structure. This allows for a reduction in construction costs and installation area by 60% or less compared to conventional methods.

[0033] Second, by configuring a hoisting mechanism for small cargo, the actual lifting and lowering power of the car section for small cargo is formed on the MRL (Machine Room Less) room section, and precision hoisting suitable for small cargo weighing 300 kg or less is formed. By forming an upper head-type H-beam section at a height of 500 mm from the lower horizontal frame of the MRL (Machine Room Less) room section and forming a hoisting mechanism for small cargo on the upper head-type H-beam section, the space can be reduced by 60% or less compared to the existing method.

[0035] Third, by configuring a counterweight section for small cargo, the load on the drive motor section for small cargo can be reduced to 40% or less compared to the existing one, power consumption can be reduced to 60% or less compared to the existing one, lifting stability can be improved by 80% compared to the existing one, and the impact during braking can be reduced to 40% or less compared to the existing one.

[0037] Fourth, by configuring a guide beam contact pressure type cargo car elevator inspection lock, accidental ascent and descent of the small cargo car during inspection is mechanically blocked. Unlike conventional methods that simply block control signals, the degree of freedom of movement is physically suppressed through an actual contact pressure structure with the left car guide beam and the right car guide beam, thereby improving the safety of the inspector by 80% compared to conventional methods. Furthermore, since it can be installed compactly in the narrow space of the car frame or the bottom of the door without the need for separate large locking equipment, it is suitable for small MRL cargo car elevators. With a 2-channel structure and multiple locations—specifically the left and right directions on one side of the upper part of the small cargo car and the left and right directions on one side of the lower part—the uneven load, twisting, and minute shaking of the small cargo car can be reduced to less than 10% compared to conventional methods. Additionally, since the start and release of the inspection mode are linked with the small cargo smart control unit, the inspector can easily establish and release the inspection lock state.

[0039] Fifth, by configuring a smart control unit for small cargo, "movement control" and "stopping safety" do not exist separately as in the past; instead, operation control and safety control are analyzed simultaneously and immediately reflected within the same judgment system, thereby increasing the overall system responsiveness by 1.5 to 2 times compared to the past. Furthermore, it is possible to provide an MRL smart step-stop type 300kg small cargo safety elevator capable of controlling operation by performing a complex analysis of the small cargo car unit's current location, how fast it is moving, whether deceleration is normal, whether the door status is safe, and whether it is nearing the end. Additionally, when an inspector inspects the cargo car elevator, the dedicated smart control effect tailored to the specific characteristics of small cargo can be improved by 80% compared to the past through the guide beam contact pressure type inspection lock control effect of the inspection drive control signal that responds during software switching. With a highly safe inspection environment, maintenance can be shortened by 1.5 to 2 times compared to the past. Brief explanation of the drawing

[0051] Next, the fourth difference between the present invention and existing technology is that, depending on the site conditions, one of the 1UP automatic door, 1UP manual door, half-type up-and-down opening automatic door, or half-type left-and-right opening automatic door is formed to be selected on the same platform.

[0053] Next, the fifth difference between the present invention and existing technology is that the guide beam contact pressure type cargo car elevator inspection lock is configured to apply deceleration, gripping, and stopping in sequence, thereby strengthening the safety stopping performance by 1.5 to 3 times compared to existing methods when an operator performs repairs or maintenance in the event of overspeed or abnormal conditions.

[0078] The inspection port (130) above serves to form an access passage for inspecting the small cargo hoisting unit, small cargo drive motor unit, small cargo governor, small cargo rail unit, and small cargo smart control unit installed inside the elevator shaft.

[0079] This is an essential access part that ensures maintainability in a top-head type H-beam concentrated MRL (Machine Room Less) structural 300kg small cargo elevator forming device, and is configured with an inspection opening frame, an inspection door for opening and closing, a locking device, a safety interlock, a step for worker access, a handle, an internal lighting interlock, and a fall prevention safety member.

[0081] Fourth, the cable wiring support member (140) according to the present invention will be described.

[0082] The above cable wiring support (140) serves to support and organize power cables, control cables, sensor wiring, door interlocking wires, and safety circuit wiring placed inside the elevator shaft.

[0083] As shown in FIG. 5, this consists of a cable tray, cable clamp, wiring fixing bracket, wiring duct, flexible cable support, cable tie, protective tube, wiring inlet reinforcement, and bending guide.

[0085] Fifth, the buffer installation part (150) according to the present invention will be described.

[0086] The above buffer installation part (150) is formed in the lower pit area of ​​the elevator shaft and serves as a base part for installing a buffer to absorb shock when the small cargo car part and the small cargo counterweight part move abnormally to the lowest level.

[0087] As illustrated in FIG. 5, this consists of a pit floor fixing part, a buffer base plate, an anchor bolt, a reference plane for position alignment, a reinforcing plate for load transfer, a substructure for shock dispersion, a car-side buffer mounting bracket, and a counterweight-side buffer mounting bracket.

[0089] Through this configuration, a small cargo car frame section is formed within the internal space of the small cargo elevator shaft section, and a lifting path is formed within the small cargo car frame section in which a small cargo rail section, a small cargo car section, and a small cargo counterweight section move up and down.

[0090] Next, the movement of the small cargo car is guided through the small cargo rail section during driving.

[0091] Next, as the small cargo hoisting unit and small cargo drive motor unit installed on the upper head-type H-beam part operate, the wire rope unit for hoisting the small cargo moves, and the small cargo car unit is raised and lowered between floors.

[0093] In addition, based on the small cargo elevator shaft section according to the present invention having a loading capacity of 300 kg, car internal dimensions (W1000 × D1000 × H1200), a rope type hoisting machine, a counterweight section for small cargo, an MRL structure, a low speed of 20~30 m / min, and being exclusively for small cargo, the internal dimensions of the elevator shaft are formed with a width of 200 cm and a length (depth) of 180 cm, and the external dimensions of the elevator shaft are formed with a width of 230 cm and a length (depth) of 210 cm, the pit floor is 90 cm, the floor height from 1F to 1RF is 340 cm, the floor height from 1RF to 2F is 240 cm, and the MRL (Machine Room Less) room section is 205 cm, so that the total height is formed to be approximately 875 cm.

[0095] Thus, by configuring the small cargo elevator shaft section according to the present invention, the hoisting machine and control panel are not installed together in a separate machine room like conventional elevators; instead, the hoisting machine, sheave, control device, small cargo governor, and inspection port are concentrated in the upper head-type H-beam section of the upper head section within the elevator shaft, thereby creating an upper head-type H-beam concentrated MRL (Machine Room Less) structure, which allows for a reduction in construction costs and installation area by 60% or less compared to conventional methods.

[0097] Next, a small cargo car part (200) according to the present invention will be described.

[0098] The above small cargo car section (200) is located inside the small cargo elevator section and is formed in a box shape, and serves to load small cargo weighing 300 kg or less and then transport it to each floor.

[0099] As illustrated in FIG. 6, this consists of a car floor, car wall plate, car ceiling, car door, door frame joint, loading space, and floor reinforcement for shock dispersion.

[0100] In addition, the car wall panels, car ceiling, car door, door frame joints, and impact-dispersing floor reinforcements are made of STS 1.2t H / L (Hair Line finish), and the car floor is made of CHK'D PL (Checkered Plate) 3.2t.

[0101] Here, CHK'D PL(Checkered Plate) 3.2t refers to a steel plate with a thickness of 3.2 mm and an anti-slip protrusion pattern formed thereon.

[0102] The size (Inside) of the small cargo car part according to the present invention is formed as (W)1000 × (D)1000 × (H)1200.

[0103] Depending on the purpose of use and shape, it is formed as (W)800 × (D)800 × (H)1000, (W)1200 × (D)1200 × (H)1400, or (W)1500 × (D)1500 × (H)1800.

[0105] That is, when a small cargo weighing 300 kg or less is loaded inside the small cargo car section, the small cargo car section is supported through the small cargo car frame section and rises or falls according to the movement of the small cargo lifting wire rope section.

[0106] Next, after a precise stop at the arrival floor, the small cargo door is opened so that small cargo weighing 300 kg or less is brought in or taken out.

[0108] Next, a small cargo car frame part (300) according to the present invention will be described.

[0109] The above small cargo car frame section (300) is located in the internal space of the elevator shaft inner wall structure and forms the framework of the small cargo elevator shaft section, structurally supports the entire small cargo car section, and serves to connect with the small cargo hoisting wire rope section, connect guide shoes, connect with the guide beam contact pressure type cargo car elevator inspection lock section, and transmit load.

[0110] As shown in FIG. 7, this consists of a vertical frame (310) for the MRL (Machine Room Less) room section, an upper horizontal frame (320) for the MRL (Machine Room Less) room section, a lower horizontal frame (330) for the MRL (Machine Room Less) room section, an upper head-type H-beam section (340), a vertical frame (350) for the 2F, a lower horizontal frame (360) for the 2F, a vertical frame (370) for the 1RF, a lower horizontal frame (380) for the 1RF, a vertical frame (390) for the 1F, a lower horizontal frame (390a) for the 1F, and a vertical frame (390b) for the pit.

[0111] And, when connecting adjacent vertical frames and vertical frames, and between a vertical frame and an upper horizontal frame, a connecting base plate (390c) having multiple bolt holes is formed and configured.

[0112] Here, the connecting base plate (390c) is formed with a size of 100×100×3.2t.

[0114] The vertical frame for the MRL (Machine Room Less) room section, the vertical frame for the 2F, the vertical frame for the 1RF, and the vertical frame for the 1F are formed with a vertical length of 2000mm.

[0115] In addition, the upper horizontal frame for the MRL (Machine Room Less) room, the lower horizontal frame for the MRL (Machine Room Less) room, the lower horizontal frame for the 2F, the lower horizontal frame for the 1RF, and the lower horizontal frame for the 1F are formed with a horizontal length of 1430 mm.

[0116] In addition, the vertical frame for the pit is formed with a vertical length of 800 mm.

[0118] According to the present invention, a vertical frame for the MRL (Machine Room Less) room section, an upper horizontal frame for the MRL (Machine Room Less) room section, a lower horizontal frame for the MRL (Machine Room Less) room section, an upper head-type H-beam section, a vertical frame for 2F, a lower horizontal frame for 2F, a vertical frame for 1RF, a lower horizontal frame for 1RF, a vertical frame for 1F, a lower horizontal frame for 1F, and a vertical frame for the pit are connected by bolting a connecting base plate to form the MRL (Machine Room Less) room section (300a), an overhead section (300b), a travel height (300c), and a pit (300d), as shown in FIG. 8.

[0120] The above MRL (Machine Room Less) room section (300a) is formed by creating a hoisting unit for small cargo and a driving motor unit for small cargo on an upper head-type H-beam section, and is formed to a height of 2050mm.

[0122] The above overhead (300b) forms the height from the top floor level to the ceiling of the elevator shaft, and is 2400mm high.

[0124] The above travel height (300c) forms the distance between the lowest floor and the highest floor where the small cargo car part actually moves, and is 3400mm high.

[0126] The above-mentioned pit (300d) forms a lower space formed below the lowest floor and is 900mm high.

[0128] The above MRL (Machine Room Less) room height, overhead height, and travel height are configured to have various heights depending on the purpose of use and form.

[0130] Thus, by configuring the small cargo car frame part according to the present invention, the load of the small cargo car part is stably supported, structural deformation when uneven load occurs is reduced to 40% or less compared to the existing method, and car vibration and twisting can be reduced to 60% or less compared to the existing method.

[0132] Next, a hoisting unit (400) for small cargo according to the present invention will be described.

[0133] The above small cargo hoisting unit (400) is positioned on the upper head-type H-beam portion of the small cargo car frame portion and receives rotational force from the small cargo drive motor portion to rotate the sheave and move the wire rope portion for small cargo hoisting, thereby performing the role of hoisting to move the small cargo car portion and the small cargo counterweight portion up and down.

[0134] As illustrated in FIGS. 9 and 10, this consists of a hoisting body (410), a sheave (420), a reduction gear (430), a bearing housing (440), a brake linkage part (450), and a frame fixing part (460).

[0136] As shown in FIG. 10, the above hoisting body (410) is formed in an integrated cylindrical-box shape and serves to protect and support each device from external pressure.

[0137] This is configured such that a sheave is formed on one side, a reduction gear is formed on one side of the internal space, a bearing housing is formed on one side of the sheave shaft or the reduction gear output side, a brake interlocking part is formed on one side of the sheave, and a frame fixing part is formed on one side of the bottom surface.

[0138] In addition, a power drive unit for the hoisting machine is formed and configured on one side of the rear.

[0139] Here, the power drive unit for the hoist is driven according to the control signal of the smart control unit for small cargo.

[0141] The sheave (420) is formed as a pulley structure on one side of the hoisting body and serves to convert the rotational force of the drive motor for small cargo into linear motion of the wire rope for hoisting small cargo.

[0142] This is formed in a disc shape and has a rope groove formed on the outer surface, configured to allow wire rope sections for hoisting small cargo to be hung parallel to it.

[0144] The above reduction gear (430) is located on one side of the internal space of the hoisting body and serves to reduce the high-speed rotational force input from the small cargo drive motor unit and increase the torque to output to the sheave.

[0146] The above bearing housing (440) serves to accommodate and support a bearing installed on a sheave shaft or a reduction gear output shaft.

[0148] The above brake linkage unit (450) is located on one side of the sheave and serves to brake the rotation of the sheave when the drive motor unit for small cargo stops operating, a stop command occurs, or an emergency condition occurs.

[0149] This consists of a brake drum, brake shoe, electronic brake coil, and brake lever.

[0150] And, it is driven according to the control signal of the smart control unit for small cargo.

[0152] The above frame fixing part (460) serves to fix the hoisting body to the upper head-type H-beam part of the small cargo car frame part.

[0153] This consists of a fixed base plate, a fastening bracket, an H-beam connecting flange, an anchor bolt, a vibration-absorbing pad, a leveling sheam plate, a positioning slot hole, and reinforcing ribs.

[0155] With this configuration, it performs the roles of changing the direction of the rope, inducing rope movement, and transmitting frictional force.

[0157] In other words, when an operation command is input from the smart control unit for small cargo, the drive motor unit for small cargo rotates, and the rotational force is transmitted to the hoisting unit for small cargo.

[0158] Next, the small cargo hoisting machine moves the wire rope section for hoisting small cargo by rotating the sheave, which is one of its components.

[0159] Next, the small cargo car part rises or falls, and the small cargo counterweight part moves in the opposite direction.

[0161] In this way, by configuring a hoisting mechanism for small cargo, the actual lifting and lowering power of the car section for small cargo is formed on the MRL (Machine Room Less) room section, and precision hoisting suitable for small cargo weighing 300 kg or less is formed. By forming an upper head-type H-beam section at a height of 500 mm from the lower horizontal frame of the MRL (Machine Room Less) room section and forming a hoisting mechanism for small cargo on the upper head-type H-beam section, the space can be reduced by 60% or less compared to the existing method.

[0163] Next, a drive motor unit (500) for small cargo according to the present invention will be described.

[0164] The above-mentioned drive motor unit (500) for small cargo is located on one side of the hoisting unit for small cargo and serves to generate rotational force and transmit it to the hoisting unit for small cargo.

[0165] This consists of a 3-phase 380V power input section, a 1.5kW to 2.2kW class drive motor, a motor rotor, a motor shaft, a cooling section, and a brake linkage section.

[0166] And, it is driven according to the control signal of the smart control unit for small cargo.

[0168] That is, when a driving command and frequency and voltage control signals are applied to the smart control unit for small cargo, a 1.5kW to 2.2kW class drive motor rotates at a set rotational speed and torque.

[0169] Next, the rotational force is transmitted to the hoisting unit for small cargo.

[0171] Next, a wire rope section (600) for hoisting small cargo according to the present invention will be described.

[0172] The above-mentioned wire rope section (600) for lifting small cargo is connected to the small cargo car section and the small cargo counterweight section based on the sheave of the small cargo lifting unit, receives rotational force from the small cargo lifting unit, and winds the wire rope to transmit vertical movement force to the small cargo car section and the small cargo counterweight section.

[0173] This consists of a hoisting wire rope (8Φ × 3 strands: 8mm diameter wire rope × 3 strands (3 lines)), a rope fixing part, a rope end fastening part, and a tension distribution structure.

[0174] In addition, one end of the wire rope section for hoisting small cargo is connected to one side of the upper part of the small cargo car section, and the other end of the small cargo car section is connected to the small cargo counterweight section, so that it operates on a seesaw principle where when one side goes up, the other side goes down.

[0175] The counterweight portion for small cargo according to the present invention is not merely a weight suspended on the opposite side of the small cargo car portion, but plays an important role in weight balance, motor load reduction, power saving, and operational stability.

[0177] With this configuration, when the sheave of the small cargo hoisting unit rotates, the wire rope section for hoisting small cargo moves, and the car section and the counterweight section for small cargo move in opposite directions.

[0178] Next, when the carbure goes up during upward operation, the counterweight goes down, and

[0179] When driving downward, it performs a seesaw motion that operates in the opposite direction.

[0181] Thus, by configuring the wire rope section for hoisting small cargo according to the present invention, load distribution is supported, tensile stability is secured, fatigue life is improved by 80% compared to conventional methods, and anti-slip and drive stabilization are achieved.

[0183] Next, a governor wire rope section (700) for small cargo according to the present invention will be described.

[0184] The above-mentioned small cargo governor wire rope section (700) is located on one side of the small cargo hoisting unit and is connected to the guide beam contact pressure type cargo car elevator inspection locking unit, and plays the role of detecting the speed of the small cargo car section when the small cargo car section moves up and down and transmitting it to the small cargo smart control unit.

[0185] As shown in FIGS. 11 and 12, this consists of a governor pulley (710), a small cargo governor (720), a governor wire rope (730), an upper governor wheel linkage (740), a lower tension maintaining part (750), and a safety device connecting part (760).

[0187] As shown in FIGS. 12 and 13, the governor pulley (710) is formed as a circular roller and serves to wind or unwind the governor wire pulley.

[0189] As shown in FIGS. 12 and 13, the above-mentioned small cargo governor (720) serves to sense the speed when the small cargo car part moves up and down while the governor wire rope is vertically penetrated.

[0190] This transmits the sensed lifting and lowering transport speed sensing data to the smart control unit for small cargo.

[0192] The governor wire rope (730) above is formed from 8Φ × 1 strand (8mm diameter wire rope × 1 strand (1 line)).

[0194] Through this configuration, the governor wire rope section for small cargo moves in conjunction with the lifting and lowering movement of the small cargo car section.

[0195] Next, when the small cargo car unit is overspeeding, this is sensed and transmitted to the small cargo smart control unit.

[0196] Next, the smart control unit for small cargo generates an emergency stop trigger signal to activate the guide beam contact pressure type cargo car elevator inspection lock.

[0197] At this time, the small cargo car section is mechanically braked by the small cargo rail section through the operation of the guide beam contact pressure type cargo car elevator inspection lock.

[0199] Next, a counterweight portion (800) for small cargo according to the present invention will be described.

[0200] The above-mentioned small cargo counterweight section (800) is located on one side opposite to the small cargo car section, separated from the small cargo car section, within the small cargo elevator section, and serves to balance the self-weight of the small cargo car section and a load of 300 kg or less, thereby forming a seesaw motion.

[0201] This consists of a weight block (810), a weight frame (820), a guide shoe (830), and a rope connection (830), as illustrated in FIGS. 14 and 15.

[0203] Through the configuration of the small cargo counterweight section above, a seesaw motion is formed in which the small cargo counterweight section descends when the small cargo car section rises, and the small cargo counterweight section rises when the small cargo car section descends.

[0204] The equilibrium of the entire lifting system is maintained through this seesaw motion.

[0206] The following mathematical formula explains why the counterweight unit for small cargo according to the present invention operates like a seesaw and maintains the equilibrium of the entire lifting system.

[0208] As explained above, the small cargo car unit and the small cargo counterweight unit are an opposing motion system connected by a single rope, and the small cargo counterweight unit offsets the car's own weight and a portion of the load; as a result, the small cargo drive motor unit is designed to operate under the control of the small cargo smart control unit to overcome only the "unbalanced load" rather than the total load.

[0210] First, the symbols are as follows.

[0212] m c represents the dead weight (kg) of the small cargo car, and m l represents the load of the loaded cargo (kg), and m w represents the mass (kg) of the counterweight for small cargo, and g is the acceleration due to gravity (9.81 m / s² 2 It represents ), where a is the acceleration (m / s²) of the small cargo car part. 2 ) represents, and T represents the wire rope tension (N).

[0214] The total mass of the small cargo car part is expressed as in the following mathematical formula 1.

[0216]

[0218] Next, since the small cargo car section and the small cargo counterweight section are connected to the same rope, in a 1:1 roping structure, the distance traveled, speed, and acceleration are expressed as Equation 2, which has the same magnitude and opposite direction.

[0220]

[0222] Here, x c indicates the location of the small cargo car section, and x w indicates the position of the counterweight section for small cargo.

[0223] Differentiating the above mathematical formula 2 with respect to time yields the following mathematical formula 3.

[0225]

[0226]

[0228] If we differentiate Equation 3 once more, it is expressed as Equation 4.

[0230]

[0231]

[0233] The above mathematical formula 4 is the basic mathematical formula of seesaw motion.

[0234] In other words, if one side goes up, the other side goes down by the same amount, and if one side accelerates, the other side accelerates in the opposite direction by the same magnitude.

[0236] Next, when the small cargo car part is at a standstill or constant speed, the force equilibrium on the small cargo car part side is expressed as Equation 5.

[0238]

[0240] And, the force balance on the counterweight side for small cargo is expressed as in the following mathematical equation 6.

[0242]

[0244] Therefore, if Equation 5 and Equation 6 are in perfect equilibrium, it is expressed as Equation 7.

[0245]

[0246]

[0248] However, in actual design, the loading capacity in ml changes continuously, so it is not possible to make the load exactly the same when the cargo is 0 kg and when it is 300 kg.

[0249] Therefore, the actual counterweight for small cargo is expressed as shown in the following mathematical formula 8.

[0250]

[0252] Here, m r represents the rated load, and α is the compensation ratio, usually around 0.4 to 0.5.

[0254] The above mathematical formula 8 is expressed as the following mathematical formula 9 by applying the α compensation ratio.

[0256]

[0258] For example, if the rated load of the 300kg small cargo elevator according to the present invention is 300kg, m r =300, and if the counterweight for small cargo is set to 50% of the car's own weight + rated load, it is expressed as the following mathematical formula 10.

[0260]

[0261]

[0263] In other words, the typical primary standard is that the counterweight for small cargo is set to the car's own weight + 150 kg.

[0265] Next, unbalanced loads will be explained.

[0267] In an actual 300kg small cargo elevator, the small cargo drive motor unit must overcome not the total load, but the unbalanced load.

[0269] If the unbalanced mass is denoted as mu, it is expressed as in the following mathematical equation 11.

[0270]

[0272] If Equation 11 is converted into force, the unbalanced force is expressed as Equation 12 below.

[0274]

[0275] Here, the closer this value is to 0, the better the equilibrium is.

[0277] Next, we will explain why equilibrium is maintained through seesaw motion.

[0279] When the small cargo car unit rises, the small cargo counterweight unit descends, so the small cargo drive motor unit only needs to add force equal to the difference between the two masses.

[0281] That is, the ideal driving force required for raising the small cargo car part is expressed as in the following mathematical formula 13.

[0283]

[0285] Here, F f represents frictional resistance, and a eq represents the equivalent acceleration term.

[0287] Since a=0 for constant speed operation, it is expressed as in the following mathematical equation 14.

[0289]

[0291] In other words, if there were no counterweight section for small cargo, the drive motor section for small cargo (m c +m l You have to lift the entire g, but if there is a counterweight section for small cargo, you only need to handle the difference.

[0293] This is the core principle by which equilibrium is maintained through seesaw motion.

[0295] For example, car weight m cg is 250kg, and the rated load m r This is 300kg, and the counterweight section for small cargo m w If this is 400kg and the counterweight is 300kg, m l = 300, and substituting the total mass of the small cargo car part into Equation 1 gives 250 + 300 = 550, and substituting the unbalanced mass into Equation 11 gives m u =550-400=150.

[0296] Next, substituting the unbalanced force into Equation 12, F u =150×9.81=1471.5N.

[0298] That is, when the maximum load is applied, the small cargo car unit becomes heavier and tends to go down, and to go up, the small cargo drive motor unit is driven under the control of the small cargo smart control unit to overcome this difference.

[0300] Thus, by configuring the counterweight unit for small cargo according to the present invention, the load of the drive motor unit for small cargo can be reduced to 40% or less compared to the existing one, power consumption can be reduced to 60% or less compared to the existing one, lifting and lowering stability can be improved to 80% compared to the existing one, and the impact during braking can be reduced to 40% or less compared to the existing one.

[0302] Next, a rail section (900) for small cargo according to the present invention will be described.

[0303] The above small cargo rail section (900) is formed along the inner wall of the small cargo elevator section in a vertical longitudinal direction on both sides of the movement path of the small cargo car section and the small cargo counterweight section, and serves to guide the small cargo car section and the small cargo counterweight section to move vertically without shaking.

[0304] In addition, depending on the purpose of use and form, when viewed from the front, it consists of a left small cargo rail section located on one side of the left of the small cargo car section and a right small cargo rail section located on one side of the right of the small cargo car section.

[0305] As shown in FIG. 16, this consists of a car guide beam (910) and a counterweight guide beam (920).

[0307] As shown in FIG. 6, the above car guide beam (910) serves as a reference straight member that guides the small cargo car section vertically without shaking within the elevator shaft.

[0308] When viewed from the front, it consists of a left car guide beam and a right car guide beam.

[0309] And, it is fixed to the inner wall structure of the elevator shaft of the small cargo elevator section with a rail fixing bracket and formed along the vertical longitudinal direction.

[0311] As shown in FIG. 15, the above counterweight guide beam (920) serves as a rail that guides the counterweight section for small cargo to move stably in the vertical direction within the elevator shaft.

[0313] That is, the small cargo car section and the small cargo counterweight section come into contact with or are guided by the small cargo rail section through the guide shoe, allowing for vertical movement.

[0314] During inspection, the guide beam contact pressure type freight car elevator inspection lock mechanically brakes the small cargo rail section, stopping the movement of the small cargo car section.

[0316] Next, a guide beam contact pressure type cargo car elevator inspection locking part (900a) according to the present invention will be described.

[0317] The above guide beam contact pressure type cargo car elevator inspection lock (900a) is formed with a 2-channel (= 2) structure on one side of the upper and lower portions of the small cargo car, and when an inspector inspects the cargo car elevator or switches software, it reacts and comes into contact with the guide beam located in the small cargo rail portion with a force of 300 kg·f having horizontal linear motion, thereby temporarily blocking the vertical movement freedom of the small cargo car portion, and performs the function of returning it to its original state after the inspection is completed.

[0318] As shown in FIG. 17, this is composed of a 2-channel (=2 units) structure consisting of a left car guide beam contact pressure type cargo car elevator inspection lock (900a-1) and a right car guide beam contact pressure type cargo car elevator inspection lock (900a-2).

[0320] [Left car guide beam contact pressure type freight car elevator inspection lock part (900a-1)]

[0322] The above-mentioned left car guide beam contact pressure type cargo car elevator inspection lock (900a-1) is located on the left side of the upper side or the left side of the lower side of the small cargo car section, and with a force of 300 kg·f having horizontal linear motion, it comes into contact with the left car guide beam located on the left small cargo rail section, thereby temporarily blocking the vertical movement freedom of the small cargo car section, and performs the function of returning it to its original state after the inspection is completed.

[0462] This is composed of a door closing signal input processing unit, a landing door closing signal input processing unit, an interlock engagement status input processing unit, a door opening / closing comparison judgment unit, a door status abnormality determination unit, an operation permission signal generation unit, a door opening operation blocking signal generation unit, and a door status warning output unit, in order to analyze and control whether the door is completely closed, whether the landing door of each floor is closed, whether an interlock is engaged, whether the door closing signal and the position signal match, and whether an operation command is received while the door is open, rather than simply analyzing whether the door is open or closed.

[0464] The above abnormal state judgment logic control unit (900d-2) analyzes the input signals and input signals regarding the input small cargo governor, 1F floor position sensor, 1RF floor position sensor, 2F floor position sensor, deceleration sensor, upper and lower limit switches, end detection sensor unit, and small cargo control panel unit, and controls the small cargo car unit to determine whether it has deviated from the normal operation range.

[0465] This is configured to determine abnormal driving conditions such as overspeed, risk of falling, operation with door open, position abnormality, poor deceleration, exceeding upper / lower limits, abnormal approach to end position, sensor signal mismatch, governor speed abnormality, abnormal vibration due to rail micro-deformation, uneven load, or tilting, by including a governor sensing signal analysis unit, a position sensor signal comparison analysis unit, a deceleration sensor judgment unit, a limit switch status judgment unit, an end detection sensor analysis unit, a door status abnormality interlocking judgment unit, a speed-position correlation judgment unit, a fall risk estimation logic unit, an abnormal state grade classification unit, and a judgment unit for whether an emergency stop is necessary.

[0467] The above inspection drive trigger output control unit (900d-3) plays the role of controlling the output of an inspection drive control signal that temporarily blocks the vertical movement freedom of the small cargo car unit by reacting when the inspector inspects the cargo car elevator and switches software, and by making contact with the guide beam located in the small cargo rail unit with a horizontal linear motion force of 300 kg·f.

[0468] This is configured to include an emergency stop permission judgment unit, a trigger signal generation unit, an output level control unit, an operating link drive signal output unit, an emergency brake interlock output unit, a re-output prevention logic unit, an emergency state maintenance latch unit, and a pre-return re-operation blocking unit.

[0470] The above small cargo parking reference floor control logic unit (900d-4) plays the role of controlling the small cargo car unit to return to the reference floor 1F when there is no call or when a waiting time of 5 to 15 minutes has elapsed.

[0471] This is configured to include a reference floor setting value storage unit, a no-call time counter unit, a current floor comparison judgment unit, an automatic return command generation unit, a reference floor arrival confirmation unit, a standby mode switching unit, and a parking priority determination unit.

[0473] The above small cargo door interlock control unit (900d-5) controls the opening of the interlocked 1F floor door, 1RF floor door, and 2F door only when the small cargo car unit arrives at the 1F floor door, 1RF floor door, and 2F door of the small cargo elevator shaft unit and safety conditions are met.

[0474] This consists of a door lock connection control unit, an interlock switch recognition control unit, and a door closing detection control unit.

[0476] As the smart control unit for small cargo according to the present invention is configured in this manner, "moving control" and "stopping safety" do not exist separately as in the past; instead, operation control and safety control are analyzed simultaneously and immediately reflected within the same judgment system, thereby increasing the overall system responsiveness by 1.5 to 2 times compared to the past. Furthermore, it is possible to provide an MRL smart step-stop type 300kg small cargo safety elevator capable of controlling operation by performing a complex analysis of where the small cargo car unit is currently located, how fast it is moving, whether deceleration is normal, whether the door status is safe, and whether it is nearing the end. Additionally, when an inspector inspects the cargo car elevator, the dedicated smart control effect tailored to the specific characteristics of small cargo can be improved by 80% compared to the past through the guide beam contact pressure type inspection lock control effect of the inspection drive control signal that responds when switching software. This creates a highly safe inspection environment, allowing maintenance to be shortened by 1.5 to 2 times compared to the past.

[0478] The specific process of the guide beam contact pressure type MRL smart inspection lock type 300kg small cargo safety elevator formation control method according to the present invention will be described below.

[0480] FIG. 37 is a flowchart illustrating a control method for forming a guide beam contact pressure type MRL smart inspection lock type 300kg small cargo safety elevator according to the present invention.

[0482] First, as shown in FIG. 30, a lifting path is formed through the small cargo elevator shaft section, through which the small cargo car section and the small cargo counterweight section move up and down, and an installation base is formed for installing the small cargo rail section, the small cargo hoisting wire rope section, the small cargo governor wire rope section, the small cargo position detection section, and the guide beam contact pressure type cargo car elevator inspection lock section (S10).

[0483] That is, as illustrated in FIG. 38, through the elevator shaft inner wall structure, an internal passage is formed to raise and lower the small cargo car and small cargo counterweight sections, as a structure forming the basic framework of the elevator shaft formed vertically inside the building (S11).

[0484] Next, the car guide beam and counterweight guide beam, which are components of the rail section for small cargo, are fixed to the inner wall of the elevator shaft through a rail fixing bracket (S12).

[0485] Next, an access passage is formed to inspect the small cargo hoisting unit, small cargo drive motor unit, small cargo governor, small cargo rail unit, and small cargo smart control unit installed inside the elevator shaft through the inspection port (S13).

[0486] Next, power cables, control cables, sensor wiring, door interlocking wires, and safety circuit wiring placed inside the elevator shaft are supported and formed through the cable wiring support (S14).

[0487] Next, through the buffer installation part, it serves as a base part for installing a buffer so that it can absorb shock when the small cargo car part and the small cargo counterweight part move abnormally to the lowest level (S15).

[0489] Next, as illustrated in FIG. 31, through the small cargo car frame section, the small cargo elevator shaft section forms the framework, structurally supports the entire small cargo car section, connects to the small cargo hoisting wire rope section, connects to the guide shoe, and connects to the guide beam contact pressure type cargo car elevator inspection lock section and transmits the load (S20).

[0490] This forms the MRL (Machine Room Less) room section (300a), overhead section (300b), travel height (300c), and pit (300d) by bolting a connecting base plate to the vertical frame for the MRL (Machine Room Less) room section, the upper horizontal frame for the MRL (Machine Room Less) room section, the lower horizontal frame for the MRL (Machine Room Less) room section, the upper head-type H-beam section, the vertical frame for the 2F, the lower horizontal frame for the 2F, the vertical frame for the 1RF, the lower horizontal frame for the 1RF, the vertical frame for the 1F, the lower horizontal frame for the 1F, and the vertical frame for the pit.

[0491] The above MRL (Machine Room Less) room section (300a) is formed by creating a hoisting unit for small cargo and a driving motor unit for small cargo on an upper head-type H-beam section, and is formed to a height of 2050mm.

[0492] The above overhead (300b) forms the height from the top floor level to the ceiling of the elevator shaft, and is 2400mm high.

[0493] The above travel height (300c) forms the distance between the lowest floor and the highest floor where the small cargo car part actually moves, and is 3400mm high.

[0494] The above-mentioned pit (300d) forms a lower space formed below the lowest floor and is 900mm high.

[0496] Next, as illustrated in FIG. 32, a hoisting mechanism for small cargo is formed on the upper head-type H-beam portion of the car frame portion for small cargo, a drive motor portion for small cargo is formed on one side of the hoisting mechanism for small cargo, and a smart control portion for small cargo is formed on one side of the drive motor portion for small cargo (S30).

[0498] Next, as shown in FIG. 33, a small cargo car section and a small cargo counterweight section are formed on one side of the lower direction of the small cargo car frame section based on the small cargo hoisting machine, and the small cargo car section and the small cargo counterweight section are connected to the small cargo hoisting machine sheave through the small cargo hoisting machine wire rope section (S40).

[0500] Next, as shown in FIG. 34, a governor wire rope section for small cargo is formed on one side of a hoisting unit for small cargo, and a guide beam contact pressure type cargo car elevator inspection lock section is formed (S50).

[0502] Next, the drive motor unit for small cargo is driven under the control of the smart control unit for small cargo to generate rotational force and transmit it to the hoisting unit for small cargo (S60).

[0503] That is, when the maximum load is applied, the small cargo car unit becomes heavier and tends to go down, and to go up, the small cargo drive motor unit is driven under the control of the small cargo smart control unit to overcome this difference.

[0505] Next, through the small cargo hoisting mechanism, rotational force is transmitted from the small cargo drive motor unit to rotate the sheave and move the small cargo hoisting wire rope unit to perform the hoisting function of moving the small cargo car unit and the small cargo counterweight unit up and down (S70).

[0507] Next, the wire rope section for hoisting small cargo receives rotational force from the hoisting unit for small cargo, winds the wire rope, and transmits vertical movement force to the car section for small cargo and the counterweight section for small cargo (S80).

[0509] Next, as shown in FIG. 35, the self-weight of the small cargo car part and a load of 300 kg or less are balanced through the small cargo counterweight part to form a seesaw motion (S90).

[0510] As a result, small cargo weighing 300 kg or less, loaded in the small cargo car section, is transferred to each floor.

[0511] In addition, the small cargo door section forms a small cargo entrance and functions as a door that opens and closes during the entry and exit of small cargo, and closes during movement while ascending or descending.

[0513] Next, the small cargo car and small cargo counterweight sections are guided to move vertically without shaking through the small cargo rail section (S100).

[0515] Next, through the small cargo governor wire rope section, the speed of the small cargo car section is detected during the up and down movement of the small cargo car section and transmitted to the small cargo smart control section (S110).

[0517] Next, through the smart control unit for small cargo, when an inspector inspects the cargo car elevator, an inspection drive control signal that responds to the software switching is output to the guide beam contact pressure type cargo car elevator inspection locking unit (S120).

[0519] Finally, as illustrated in FIG. 36, a guide beam contact pressure type cargo car elevator inspection lock is formed with a 2-channel (=2) structure on one side of the upper and lower portions of the small cargo car, and when an inspector inspects the cargo car elevator or switches software, it reacts and comes into contact with the guide beam located on the small cargo rail portion with a force of 300 kg·f having horizontal linear motion, thereby temporarily blocking the vertical movement freedom of the small cargo car (S130).

[0520] And, after the inspection is complete, restore it to its original state.

[0521] That is, as illustrated in FIG. 39, the inspection lock of the left car guide beam contact pressure type cargo car elevator receives an inspection drive control signal from the smart control unit for small cargo and is driven simultaneously with the inspection lock of the right car guide beam contact pressure type cargo car elevator, and with a force of 300 kg·f having horizontal linear motion, it comes into contact with the left car guide beam located on the left small cargo rail section, thereby temporarily blocking the vertical movement freedom of the small cargo car section (S131).

[0522] Next, the inspection lock of the right car guide beam contact pressure type cargo car elevator receives an inspection drive control signal from the smart control unit for small cargo and is driven simultaneously with the inspection lock of the left car guide beam contact pressure type cargo car elevator, and with a force of 300 kg·f having horizontal linear motion, it comes into contact with the right car guide beam located on the right small cargo rail section, thereby temporarily blocking the vertical movement freedom of the small cargo car section (S132).

[0524] More specifically, the above step (S131) ​​is,

[0525] First, as illustrated in FIG. 40, for maintenance or inspection work, the inspector switches to inspection mode by turning the key of the key box or switches to inspection mode according to a control signal of the smart control unit for small cargo connected to the inspection button (S131a).

[0526] Next, the left car guide beam contact pressure type drive control linkage unit receives an inspection drive control signal as a software switching signal from the smart control unit for small cargo and transmits it to the left car guide beam contact pressure type motor (S131b).

[0527] Next, as the left car guide beam contact pressure type lead screw part rotates, the left car guide beam contact pressure type protruding beam part is advanced in a horizontal straight direction with the force of advancement (S131c).

[0528] Next, the tip of the left car guide beam contact pressure type protruding beam part comes into contact with the left car guide beam located on the left small cargo rail part (S131d).

[0529] Next, the left car guide beam contact pressure type protruding beam part is continuously pushed by a force of 300 kg·f generated by the left car guide beam contact pressure type motor and the left car guide beam contact pressure type lead screw part, thereby fixing the position so that the small cargo car part does not move in the up-and-down direction along the left small cargo rail part (S131e).

[0530] Next, when the inspection is finished, the inspection drive control signal is released, and the left car guide beam contact pressure type protruding beam part retracts to return the small cargo car part to a state where it can be operated normally (S131f).

[0532] More specifically, the above step (S132) is,

[0533] First, as illustrated in FIG. 41, for maintenance or inspection work, the inspector switches to inspection mode by turning the key of the key box or switches to inspection mode according to a control signal of the smart control unit for small cargo connected to the inspection button (S132a).

[0534] Next, the right car guide beam contact pressure type drive control linkage unit receives an inspection drive control signal as a software switching signal from the smart control unit for small cargo and transmits it to the right car guide beam contact pressure type motor (S132b).

[0535] Next, as the right car guide beam contact pressure type lead screw part rotates, the right car guide beam contact pressure type protruding beam part is advanced in a horizontal straight direction with the force of advancement (S132c).

[0536] Next, the tip of the right car guide beam contact pressure type protruding beam part comes into contact with the right car guide beam located on the right small cargo rail part (S132d).

[0537] Next, the right car guide beam contact pressure type protruding beam part is continuously pushed by a force of 300 kg·f generated by the right car guide beam contact pressure type motor and the right car guide beam contact pressure type lead screw part, thereby fixing the position so that the small cargo car part does not move in the up-and-down direction along the right small cargo rail part (S132e).

[0538] Next, when the inspection is finished, the inspection drive control signal is released, and the right car guide beam contact pressure type protruding beam part retracts to return the small cargo car part to a state where it can be operated normally (S132f). Explanation of the symbols
