Description

Incline adjustable lift device {INCLINE ADJUSTABLE LIFT}

The present invention relates to a tilt control lift device, and more specifically, when lifting an inclined section of a large building such as a bridge, the tilt control unit adjusts the tilt of the cage frame with respect to the driving frame to maintain the horizontal level of the cage. It relates to a tilt-adjustable lift device that allows smooth movement of people or transportation of goods.

In general, a construction lift is a lifting device applied to large structures such as apartments, high-rise buildings, or bridge piers, and is mainly used to transport personnel and equipment to the appropriate location by loading them into a carrier.

This lift is driven by a motor installed in the transport box, allowing the transport box to move along masts erected at the top and bottom of the building, so that it can be lifted to a corresponding position on a pier, for example.

However, in the case of a building built vertically, the transport box rises and falls vertically along the mast by the operation of the driving part, so when a person rides in the transport box, it can move stably and goods can also be transported stably, for example, at an incline. When a transport box is raised and lowered along an inclined mast on a constructed pier, the transport box is also tilted, which may reduce the stability of transport of people or goods.

Accordingly, in the conventional lift device, a method of maintaining the level of the floor surface on which people or objects are supported was applied by installing a device for adjusting the inclination at the lower end of the lift, but even in this case, the entire lift was adjusted horizontally. In addition, there was a limitation that the structure of the device for leveling was complicated.

Therefore, for example, there is a need for the development of a new configuration of a lift device that can maintain the level of the entire lift when lifting an inclined or vertical section of a bridge pier and can implement horizontal maintenance with a simple structure.

First, referring to FIG. 1, the inclination control lift device 100 according to an embodiment of the present invention is installed, for example, on a pier 1 with a height of several hundred meters, and is installed in the vertical section of the pier 1. In addition, it is a lift device 100 that can go up and down while maintaining horizontality even in an inclined section.

Hereinafter, a case where the incline control lift device 100 of this embodiment is mounted on the incline section of the pier 1 of FIG. 1 and goes up and down will be described, but the incline control lift device 100 is not limited thereto. , it is natural that it can be used in other buildings, such as high-rise buildings or construction sites.

As shown in Figures 2 and 3, the inclination control lift device 100 according to an embodiment of the present invention includes a driving frame 110 that moves up and down along a mast 10 installed in a building, and a driving frame 110. The cage frame 130, which is rotatably mounted on the cage and forms the frame of the cage 120 (transportation unit) that provides a boarding or loading space, adjusts the inclination of the cage frame 130 with respect to the driving frame 110 to control the cage ( It may include a tilt adjustment unit 150 that maintains the horizontality of 120).

In addition, it may include a sensor (not shown) that detects the degree of inclination of the cage 120 with respect to the horizontal, and a control unit (not shown) that controls the tilt adjustment unit 150 based on the sensing information of the sensor.

Due to this configuration, the horizontal level of the cage 120 is maintained by the incline adjustment unit 150 even when the incline control lift device 100 moves up and down the incline section of the pier 1, preventing movement of personnel or objects. Transportation, etc. can be carried out stably.

To describe each configuration, first, the driving frame 110 of this embodiment is a frame that is mounted to be linearly movable on the mast 10 installed in the height direction on the bridge pier 1.

Although not shown in detail, a linear guide rail may be formed on the mast 10, and correspondingly, a moving means that moves linearly along the guide rail is mounted on the rear of the driving frame 110, so the driving frame 110 Linear movement of the drive frame 110 with respect to the mast 10 can be achieved by driving force given from a drive motor mounted on.

However, since this driving frame 110 is driven along the longitudinal direction of the mast 10, as shown in FIGS. 2 and 3, the central axes of the driving frame 110 and the mast 10 coincide, Therefore, when lifting up and down the inclined section of the pier 1, the driving frame 110 has a structure in which it is tilted by the inclination of the pier 1 and moves linearly.

Referring to FIG. 3, when the mast 10 has an angle of 79 degrees from the horizontal plane, the driving frame 110 also moves linearly along the mast 10 with an inclination of 79 degrees.

Therefore, the cage 120 coupled to the driving frame 110 also has no choice but to be tilted according to the tilt of the driving frame 110. In order to solve this tilt problem, the driving frame 110 and the cage frame 130 must be mutually aligned. An operative inclination control unit 150 must be installed to adjust the inclination of the cage frame 130 with respect to the driving frame 110 so that the entire cage 120 can be maintained horizontally.

As shown in FIG. 4, the cage 120 of this embodiment includes a cage body 123 that has an automatic door 121 and a boarding or loading space, and is coupled to the cage body 123 and includes the driving frame 110 described above. ) may include a cage frame 130 that is rotatably coupled to the axis.

As described above, the driving frame 110 is moved linearly along the formation direction of the mast 10, so it can face a diagonal direction, and the cage 120 in this embodiment is maintained horizontally by the tilt adjusting unit 150. You can. In other words, due to the adjustment of the inclination of the cage frame 130 with respect to the driving frame 110, the bottom surface of the cage body 123 can face the horizontal direction.

The inclination adjusting unit 150 of this embodiment basically adjusts the inclination with respect to the driving frame 110 due to three configurations. A hinge member 160 that hinges the cage frame 130 to the driving frame 110 ) and a driving force generating member 170 that generates driving force to adjust the degree of inclination of the cage frame 130 with respect to the driving frame 110, and guides the movement of the cage frame 130 with respect to the driving frame 110. It may include a guide member 180 that does.

In other words, the cage frame 130 may be rotated with respect to the driving frame 110 around the hinge member 160. At this time, the degree of rotation of the cage frame 130 can be adjusted using the driving force generating member 170. This is possible, and at this time, the sliding movement of the cage frame 130 with respect to the driving frame 110 is guided through the guide member 180 to achieve stable operation.

To describe each configuration, first, the hinge member 160 of this embodiment is fixed to the driving frame 110, as shown in FIGS. 4 and 5, and is hinged to the cage frame 130 corresponding to its position. A hole 161 is formed so that the hinge member 160 can be coupled through the hinge hole 161. Therefore, the cage frame 130 can be rotated with respect to the driving frame 110 around the hinge member 160.

At this time, in order to prevent the hinge member 160 from falling out of the hinge hole 161 of the cage frame 130, the end portion 160a of the hinge member 160 has a larger diameter than the inner diameter of the hinge hole 161. In addition, since the bearing 165 is mounted to surround the central portion of the hinge member 160, the cage frame 130 can be rotated smoothly with respect to the driving frame 110, and can support a large load. Oil may be provided for lubrication.

Due to this hinge member 160, the position of the cage frame 130 with respect to the driving frame 110 can be adjusted, for example, as schematically shown in FIGS. 6 and 7.

However, it is required to adjust the inclination so that the cage frame 130 is horizontal when the cage frame 130 is rotated about the hinge member 160 with respect to the driving frame 110. In this embodiment, the driving force generating member The degree of rotation of the cage frame 130 with respect to the driving frame 110 can be adjusted by 170.

Although not shown in detail, the driving force generating member 170 of this embodiment is provided on a rack gear 171 provided at the lower end of the driving frame 110 and a cage frame 130 corresponding to its position, and the rack gear 171 ) may include a drive motor 175 having a pinion gear 176 corresponding to the.

The rack gear 171 and the pinion gear 176 each have corresponding teeth, and the pinion gear 176 coupled to the shaft of the drive motor 175 rotates to interact with the rack gear 171. , Therefore, rotation of the cage frame 130 with respect to the driving frame 110 can be achieved.

To elaborate, if the rotation of the cage frame 130 with respect to the driving frame 110 can be achieved by the above-described hinge member 160, the degree of rotation of the cage frame 130 is controlled by the driving force generating member 170. This allows the cage 120 to be maintained horizontally.

At this time, the degree of driving force generation of the driving force generating member 170 may be determined by the above-described sensing unit and control unit. In other words, the sensing unit detects the overall inclination of the cage 120 using, for example, a weight and sends it to the control unit, and the control unit adjusts the driving force generation degree of the driving force generating member 170 based on the sensing information, thereby controlling the driving frame. Rotation and horizontal maintenance of the cage frame 130 relative to 110 can be achieved.

The driving motor 175 of the driving force generating member 170 may be, for example, a reduction motor, but is not limited thereto.

Meanwhile, when the cage frame 130 rotates with respect to the driving frame 110 around the hinge member 160, the cage frame 130 rotates stably so that, for example, when a person rides in it, the person can feel stable. Must be able to. To this end, in this embodiment, as shown in FIGS. 5 and 6, a guide member 180 is provided at the lower part of the driving force generating member 170 to tilt the cage frame 130 with respect to the driving frame 110. Ensure that control is carried out stably.

The guide member 180 of this embodiment is, for example, a linear motor guide (LM Guide) and, as shown in FIGS. 6 and 7, is a cage frame for the drive frame 110 centered on the hinge member 160. When the rotation of 130 is performed, the sliding movement of the cage frame 130 with respect to the driving frame 110 is guided.

This guide member 180 is provided to protrude from the rear of the rail-type guide rail 181, on which the drive frame 110 is mounted and forms a movement path, and the cage frame 130, and extends along the guide rail 181. It may include a moving part 185 that slides.

The guide rail 181 has a larger width at the ends than the central portion overall, so it has an overall capital letter 'I' shape, and the moving part 185 is a 'digut' (ㄷ) surrounding the end of the guide rail 181. )' shape can prevent the moving part 185 from being arbitrarily separated from the guide rail 181.

In addition, due to the structure of the above-described guide member 180, the sliding movement of the moving part 185 with respect to the guide rail 181 can be performed smoothly, and thus the cage frame 130 with respect to the driving frame 110 can be smoothly moved. Movement can be performed stably. Therefore, when a person is riding in the cage 120 or an object is loaded, transportation can be performed stably.

Meanwhile, hereinafter, examples of the operation of the inclined lift device of this embodiment will be described with reference to FIG. 7.

FIG. 7 is a diagram for explaining the rotational operation of the cage frame with respect to the driving frame shown in FIG. 5.

As shown, the degree of rotation of the cage frame 130 with respect to the driving frame 110 may vary depending on the inclination of the inclination section of the mast 10 (see FIG. 2).

For example, as shown in the left drawing of FIG. 7, when the central axes of the driving frame 110 and the cage frame 130 have an inclination of 11 degrees, a corresponding driving force is generated by the driving force generating member 170 described above. Thus, the cage frame 130 can be rotated with respect to the driving frame 110 around the hinge member 160, and the cage 120 can be maintained horizontally.

Likewise, as shown in the right drawing of FIG. 7, when the central axes of the driving frame 110 and the cage frame 130 have an inclination of 3.2 degrees, the driving frame 110 is adjusted correspondingly using the inclination adjusting unit 150. ), the cage frame 130 can be rotated, and the cage 120 can be maintained horizontally.
