Description

Lifting system{LIFT SYSTEM}

The present invention relates to a lifting system that raises or lowers various equipment installed on high ceilings in factories, etc.

A clean room is built in the fab building of a semiconductor plant. A clean room refers to a special space created to keep dust or particulates in the indoor air to a minimum and to control indoor pressure, humidity, temperature, distribution and speed of air currents, etc. within a certain range for the purpose of preventing contamination of the working environment. .

Among the key equipment used to build a clean room in such a fab building is a fan filter unit (FFU). A fan filter unit refers to an automatically controlled filtration device that purifies the air and prevents the generation or inflow of dust into the clean room.

The fan filter unit is installed in the space above the upper ceiling of the clean room. The ceiling height of the clean room is relatively high, and generally, for installation and maintenance of the fan filter unit, a lifting device (lift) is used to raise or lower the fan filter unit and related facilities to the ceiling height of the clean room.

However, in the conventional lifting device used in the construction of equipment such as fan filter units, a worker rides the equipment on the workbench of the lifting device, moves it to the ceiling height, and then performs the task of handing over the equipment to other workers on the ceiling. At this time, the lifting operation control of the lifting device and the position control of the workbench are performed through the naked eyes of the worker riding the workbench. As such, the construction method of the fan filter unit using a conventional lifting device requires workers to directly ride on the workbench of the lifting device, and due to the nature of such high-altitude work, serious casualties may occur during the construction process.

One object of the present invention is to provide a lifting system that allows operations for installation and maintenance of equipment even if the operator does not directly board it.

Another object of the present invention is to provide a lifting system that can minimize the impact applied to loaded objects according to changes in lifting speed.

According to an example related to the present invention, the sensing unit includes: a first sensor disposed at one end of the lift unit facing the ceiling; and second and third sensors respectively disposed on one end of the lift unit and the loading unit facing the ceiling, wherein the control unit determines that the separation distance from the ceiling measured by the first sensor is a first sensor. If the value is less than the value, the rising speed of the lift unit is reduced, and if the separation distance from the ceiling measured by the second and third sensors is a second value smaller than the first value, the lift unit and the loading unit are raised and lowered. This can be done to stop each operation.

According to an example related to the present invention, the loading unit may be configured to be able to rise up to one end of the lift unit facing the ceiling.

According to an example related to the present invention, the third sensor is disposed in a peripheral area of the loading unit and operates when directly contacting the ceiling to detect each position relative to the ceiling, and the loading unit, It is formed to have an area that is larger than the area of the ceiling hole provided in the ceiling when the object is installed when viewed from a plan view, and the peripheral area may be formed to overlap the remaining portion of the ceiling excluding the ceiling hole.

According to an example related to the present invention, the lifting system is disposed on the circumference of the loading unit and generates light toward the ceiling to display the shape of the loading unit on the ceiling. It may further include a light emitting guide. .

According to an example related to the present invention, the light emitting guide is provided in plurality, is disposed on each side forming the periphery of the loading unit, and is configured to display light in the form of a line corresponding to the shape of the side on the ceiling, respectively. You can.

According to an example related to the present invention, the lifting system is installed on the loading unit and is formed to support a portion of the object loaded on the loading unit, and is configured to fix the object in a preset position. Additional brackets may be included.

According to an example related to the present invention, the lift units are each extended in one direction, one is inserted into the other and arranged to overlap, and the degree of overlap between them is adjusted as each moves along the longitudinal direction. A plurality of boom members comprising: A driving unit that provides power for movement of the plurality of boom members; A plurality of side plates each formed on an outer peripheral area of the plurality of boom members and protruding from an outer surface of the boom member; and a connection chain installed on the plurality of side plates to connect the adjacent side plates.

According to an example related to the present invention, the loading unit includes an elevating rail coupled to the lift unit and extending along the longitudinal direction of the lift unit; and a workbench on which the goods are loaded, coupled to the lifting rail and movable along the longitudinal direction of the lifting rail, and a winch installed on the lift unit. And both ends may further include a wire connected to the winch and the workbench, respectively, and the control unit may be configured to operate the winch to wind or unwind the wire to raise and lower the workbench.

According to an example related to the present invention, the moving part includes a body part forming an exterior; a plurality of first extension parts each coupled to the body part and each extending in a horizontal direction with respect to the ground around the body part; a plurality of second extension portions each provided at one end of each of the first extension portions and each capable of extending toward the ground; and a fixing device portion rotatably coupled to the second extension portion and configured to extend the second extension portion and support the second extension portion on the ground when rotated.

The effects of the present invention obtained through the above-described solution are as follows.

The lifting system includes a lift unit that is disposed on a moving unit and is capable of adjusting the length for raising or lowering, and is coupled to the lift unit, moves together when the lift unit is raised and lowered, and moves along the longitudinal direction of the lift unit independently of the movement of the lift unit. It includes a loading unit, a sensing unit that detects one end of the lift unit and the relative position of the loading unit and the ceiling, and a control unit that controls the raising or lowering operation of at least one of the lift unit and the loading unit. Here, the lifting or lowering operation of the lift unit and the loading unit performed by the control unit is performed based on the position of one end of the lift unit or the position of the loading unit detected by the sensing unit.

According to the above lifting system, even if the worker does not directly board the loading unit, the lifting operation of the lift unit and the loading unit can be stably performed depending on the relative position between one end of the lift unit and the loading unit and the ceiling. In other words, the lifting system uses a sensing unit disposed on the lift unit and the loading unit, unlike the conventional method in which the relative position of one end of the lift unit and the ceiling of the loading unit was determined by the naked eye of the worker directly on the loading unit. Based on the current position of one end of the lift unit and the loading unit detected by the sensing unit, the lifting operation of the lift unit and the loading unit can be performed stably without collision with the ceiling.

Additionally, the sensing unit may include first to third sensors. The first sensor may be placed on one end of the lift unit facing the ceiling, and the second and third sensors may be placed on one end of the lift unit and the loading unit, respectively. Here, the control unit reduces the rising speed of the lift unit when the separation distance from the ceiling measured by the first sensor is less than the first value, and the separation distance from the ceiling measured by the second and third sensors is less than the first value. If the second value is small, the lifting operation of the lift unit and the loading unit is stopped.

According to the configuration of the sensing unit and the control unit of the above-mentioned lifting system, when the position of one end of the lift unit approaches the ceiling, the rising speed of the lift unit is reduced and then the lifting operation of the lift unit and the loading unit is completely stopped. Accordingly, damage to the loaded items can be prevented by minimizing the amount of impact applied to objects such as equipment loaded on the loading part by reducing the fluctuation range of the lifting speed that occurs after the lifting motion of the lift part until the lift part completely stops.

It is primarily designed to perform the function of raising or lowering from the ceiling (C) level to the ground.

As shown in FIG. 2, the lifting system 100 can be configured to enable the handover of objects (O), such as equipment, to the worker (W) on the ceiling without the worker directly riding on it. In addition, as shown in FIG. 3, the lifting system 100 is designed to enable the handover of objects (O) such as equipment to a worker (W) placed on a workbench (B) formed to a height adjacent to the ceiling (C). , It can be done to raise objects (C) such as equipment to a height adjacent to the ceiling (C) while placed adjacent to the workbench (B). As shown in FIGS. 2 and 3, the lifting system 100 can be configured to perform lifting work without an operator directly riding on it.

To perform such lifting work, the lifting system 100 of the present invention includes a moving unit 110, a lift unit 120, a loading unit 130, a sensing unit 140, and a control unit 150.

The moving unit 110 is configured to be movable on the ground. The moving unit 110 is configured to move at least some of the main components forming the lifting system 100. The moving part 110 may include a body part 111, a first extension part 112, a second extension part 113, and a fixing device part 114.

The body portion 111 forms the exterior of the moving portion 110. A moving wheel 115 may be installed on the body portion 111. The moving unit wheel 115 may be formed to be movable along the ground. The body portion 111 may be moved by the moving wheel 115.

The first extension portion 112 may be provided in plurality, and each of the first extension portions 112 may be coupled to the body portion 111 . The plurality of first extension parts 112 may each extend in a horizontal direction with respect to the ground with the body part 111 as the center. The first extension portion 112 may be extended to have a preset length, or may be made to have an adjustable length. Additionally, the extended lengths of the plurality of first extension parts 112 may be the same, or at least some of the plurality of first extension parts 112 may have different lengths.

Additionally, the first extension portion 112 may be configured in a multi-stage structure so that each length can be adjusted. For example, when the moving part 110 moves, the length can be shortened, and when the moving part 110 is stopped for fixation, the length can be increased. Accordingly, the mobility of the lifting system 100 can be further improved by reducing the phenomenon of the first extension part 112 colliding with surrounding structures when the moving part 110 moves.

The second extension portion 113 may be provided in plurality, each provided at one end of the first extension portion 112. Additionally, the plurality of second extension parts 113 may each be formed to be extendable toward the ground. That is, the second extension portion 113 may be supported by touching the ground or may be arranged at a certain distance from the ground depending on the situation. For example, each second extension part 113 may be arranged to be spaced apart from the ground when the moving part 110 is moved, and when the moving part 110 is stopped, the moving part 110 In situations where fixation is necessary, it can be extended toward the ground and placed in a supported state on the ground.

Additionally, the handle unit 180 may be configured to limit the movement of the moving unit 110 in the second position tilted at the second angle. For example, the first position may mean a state in which the length part of the handle unit 180 is perpendicular to the ground, as shown in FIG. 5, and the second position may mean a state in which the length part of the handle part 180 is perpendicular to the ground. This may mean a state tilted at a certain angle in a counterclockwise direction from this vertical state.

Additionally, the handle unit 180 may be detachably coupled to the moving unit 110. In addition, a handle wheel 181 formed to be movable together with the moving wheel 115 may be provided at a position adjacent to one end of the handle 180 connected to the moving part 110.

The lift unit 120 may be disposed on the moving unit 110 and extend along one direction. Here, the lift unit 120 can be configured to adjust its length for raising or lowering.

The loading unit 130 provides a loading space for the object (O). The loading unit 130 is coupled to the reboot unit 120 and moves together when the lift unit 120 is raised and lowered. That is, in the initial state before the heights of both the lift unit 120 and the loading unit 130 are raised as shown in (a) of FIG. 4, the lift unit 120 as shown in (b) of FIG. 4 When only the height of is raised or lowered, the loading unit 130 coupled to the lift unit 120 rises when the lift unit 120 is raised and can be lowered together when the lift unit 120 is lowered. .

Additionally, the loading unit 130 may be configured to be movable along the longitudinal direction of the lift unit 120 independently of the movement of the lift unit 120 . That is, the loading unit 130 can be configured to independently perform a lifting operation in the absence of the lifting operation of the lift unit 120, as shown in (c) of FIG. 4. In this way, the lift unit 120 and the loading unit 130 can be configured to perform a lifting operation independently of each other.

Additionally, the loading unit 130 may be configured to be ascendable up to one end 120a of the lift unit 120 facing the ceiling C. That is, the height of the loading unit 130 may not exceed one end 120a of the lift unit 120 facing the ceiling C. According to this structure, when the lifting operation of the lift unit 120 is stopped, the maximum rising height of the loading unit 130 may be limited to one end 120a of the lift unit 120. Accordingly, the lifting height of the loading unit 130 can be indirectly controlled through controlling the raising and lowering operation of the lift unit 120 to prevent collision with the building ceiling C.

Additionally, the loading unit 130 may include a lifting rail 131 and a work table 132.

The lifting rail 131 is coupled to the lift unit 120 and may extend along the longitudinal direction of the lift unit 120. The lifting rail 131 is configured to provide a movement path for the work table 132.

The work table 132 is loaded with objects (O) and may be coupled to the lifting rail 131 to be movable along the longitudinal direction of the lifting rail.

The sensing unit 140 is disposed on the lift unit 120 and the loading unit 130, and has one end 120a of the lift unit 120 facing the ceiling C and the ceiling C of the loading unit 130. ) can be made to detect the relative position.

The sensing unit 140 may include a first sensor 141, a second sensor 142, and a third sensor 143. The first to third sensors 141, 142, and 143 may be configured to detect the relative positions of one end 120a of the lift unit 120 and the ceiling C of the loading unit 130.

The first sensor 141 may be placed at one end 120a of the lift unit 120 facing the ceiling C of the building. The first sensor 141 generates light toward the ceiling (C), and determines the relative It can be made to detect location. For example, the first sensor 141 may use a laser to generate the light to detect the relative position with respect to the ceiling C.

The second sensor 142 and the third sensor 143 may be disposed on one end 120a of the lift unit 120 and the loading unit 130, respectively, facing the ceiling C. The second and third sensors 142 and 143 may operate when directly contacting the ceiling C to detect their respective positions relative to the ceiling C. For example, the second and third sensors 142 and 143 may be configured as limit switches that perform a sensing operation through physical contact.

Meanwhile, the method of detecting the relative position of the first and second sensors 141 and 142 with respect to the ceiling C is not limited to the principle described above, and uses sound as well as light or uses an image sensor to detect the relative position of the ceiling C area. It can also be implemented by detecting images for .

The control unit 150 controls at least one of the lift unit 120 and the loading unit based on the position of the one end 120a of the lift unit 120 or the position of the loading unit 130 detected by the sensing unit 140. It can be made to control either a rising or falling motion. The control unit 150 may be placed on the handle unit 180, for example.

For example, the control unit 150 may reduce the upward speed of the lift unit 120 when the separation distance from the ceiling C measured by the first sensor 141 is less than or equal to a first value. That is, when the control unit 150 detects that the separation distance from the ceiling C is within a preset range through the first sensor 141, the lifting speed of the lift unit 120 may be reduced. there is. The separation distance from the ceiling C detected by the first sensor 141 may be set to, for example, 1 meter.

In addition, the control unit 150 operates the lift unit 120 and The lifting operation of the loading unit 130 may be stopped respectively.

According to the above lifting system 100, even if the worker (W) does not directly board the loading unit 130, the relative position between one end of the lift unit 120 and the loading unit 130 and the ceiling C of the building Depending on the location, the lifting operation of the lift unit 120 and the loading unit 130 can be performed stably. That is, the lifting system 100 of the present invention is capable of detecting the relative position of the one end 120a of the lift unit 120 and the ceiling C of the loading unit 130 by the operator directly riding the loading unit 130. (W) Unlike the conventional method that was performed with the naked eye, it can be detected through the sensing unit 140 disposed on the lift unit 120 and the loading unit 130, and the lift detected by the sensing unit 140 Based on the current positions of the one end 120a of the unit 120 and the loading unit 130, the lifting operation of the lift unit 120 and the loading unit 130 is performed stably without collision with the ceiling (C) of the building. can do.

In addition, according to the configuration of the sensing unit 140 and the control unit 150 of the lifting system 100 as described above, the point at which the position of one end 120a of the lift unit 120 approaches the ceiling C of the building The rising speed of the lift unit 120 is reduced and then the lifting operation of the lift unit 120 and the loading unit 130 is completely stopped. Accordingly, the amount of impact applied to objects O such as equipment loaded on the loading unit 130 is reduced by reducing the fluctuation range of the lifting speed that occurs after the lifting operation of the lift unit 120 until the lift unit 120 is completely stopped. By minimizing damage to loaded items, you can prevent damage.

Hereinafter, the characteristics of the loading unit 130 related to the structure of the ceiling C will be described with reference to FIG. 8.

FIG. 8 is a conceptual diagram of the loading unit 130 of the lifting system 100 shown in FIG. 2 viewed from above the ceiling C.

Referring to FIG. 8 , the third sensor 143 may be disposed in the peripheral area 130a of the loading unit 130. In addition, the third sensor 143 may operate when directly contacting the ceiling C to detect each position relative to the ceiling C.

Here, the loading unit 130 has an area that is larger than the area of the ceiling hole C1 provided in the ceiling C of the building when the object O is installed when viewed from a plane, as shown in FIG. 8. The peripheral area 130a of the loading unit 130 may be formed to overlap the remaining portion C2 of the ceiling C excluding the ceiling hole C. That is, the loading unit 130 may be formed to have an area larger than the area of the ceiling hole C1 provided in the ceiling C for installation of objects O such as equipment when viewed from a plan view.

According to the structure of the third sensor 143 and the loading unit 130 as described above, when the loading unit 130 is raised, the peripheral area 130a of the loading unit 130 is connected to the ceiling excluding the ceiling hole C1. It can be made to stably contact the remaining part (C2) of (C). Accordingly, when the loading unit 130 is raised, the loading unit 130 passes through the ceiling hole C1 to prevent the detection operation of the third sensor 143 from being performed normally, The lifting operation of the loading unit 130 can be stably controlled up to the height of the ceiling (C).

At this time, the plurality of light emitting guides 160 may be configured to display light 160a in the form of a line corresponding to each side forming the circumference of the loading unit 130 on the ceiling C.

For example, as shown in FIG. 9, when the shape of the loading part 130 is square when viewed from a plane, the light emitting guide 160 is 4 forming the circumference of the square-shaped loading part 130. It can be placed on each side. And, when light is generated from the plurality of light emitting guides 160 toward the ceiling C, a shape corresponding to the square shape of the loading unit 130 may be displayed in a square shape on the ceiling C of the building. Additionally, the length of each side forming the square shape displayed on the ceiling C may be the same as the length of each side forming the perimeter of the loading unit 130. That is, the shape of the loading unit 160 viewed from a plan view may be displayed in the same manner on the ceiling C of the building.

According to the configuration of the light-emitting guide 160, during lifting work using the lifting system 100, the position of the loading unit 130 on which the object O is placed is selected by the lift unit 120 and the loading unit 130. ) can be completed before the rising operation is performed. Accordingly, it is possible to prevent a situation in which the lifting system 100 must be moved to change the position of the loading unit 130 during the operation of lifting the object O. As a result, the performance speed of lifting work using the lifting system 100 can be further improved.

The driving unit 122 may be configured to provide power for movement of the plurality of boom members 121. The driving unit 122 may be disposed adjacent to the boom member 121 as shown in FIG. 5 . However, the position of the driving unit 122 is not limited to the position shown in FIG. 5, and may be placed in another position. For example, the driving unit 122 may be disposed on the moving unit 110.
