The connecting portion 22 is fixedly connected to the horizontal support bars 44 and 54 so that the first and second support portions 40 and 50 are spaced apart from each other by a predetermined distance .

A guide space 25 is formed between the first vertical support bars 41 and 51 and between the second vertical support bars 42 and 52.

The guide module 30 includes first and second guide frames 31 and 32 disposed in guide spaces 25 formed on the right and left sides of the support module 20, A plurality of support wheels 35 and 38 which are respectively installed on the first vertical support bars 41 and 51 and are rotated in contact with the first vertical support bars 41 and 51 and the second vertical support bars 42 and 52, And a guide connector 34 for connecting the first and second guide frames 31 and 32 to the lift frame part 14 and fixing them.

The first and second guide frames 31 and 32 extend vertically and are arranged in the guide space 25, respectively.

Two guide connectors 34 are vertically arranged and fixed to the upper and lower ends of the guide frames 31 and 32 to be fixed to the lift frame part 14, respectively.

The guide connector 34 is for connecting the lift module 10 and the guide module 30 and functions not only for connection but also for dispersing the bending moment and the load due to the load of the load.

The support wheels 35 and 38 are fixed to the first and second guide frames 31 and 32 so as to suppress the back and forth shaking when moving up and down and to reduce friction and noise during movement.

The support wheels 35 and 38 are formed to be inwardly concave so as to be brought into close contact with the outer circumferential surface of the vertical support bars 41, 51, 42 and 52 formed in a cylindrical shape.

The support wheels 35 and 38 formed concavely are formed with the vertical support bars 41, 51, 42 and 52 and the vertical support bars 41, 51, 42 and 52 The lift module 10 is prevented from being deviated in the left-right direction when the lift module 10 is moved in the up-and-down direction.

In the present embodiment, two pieces are arranged on the front side surface of the first and second guide frames 31 and 32, and two pieces are arranged on the rear side surface, and are spaced apart in the vertical direction.

Here, the first guide frame 31 is disposed in close contact with the first vertical support bars 41 and 51 via the support wheels 35 and 38, And are disposed in close contact with the second vertical support bars 42 and 52, respectively.

Therefore, the first and second guide frames 31 and 32 move in a state of being in tight contact with the vertical support bars 41, 51, 42 and 52 when they are moved in the vertical direction, Movement is minimized.

The load of the load is transmitted to the first and second guide frames 31 and 32 via the guide connector 34 when the load is loaded on the rod portion 12, So that the support wheels 35 and 38 are brought into close contact with the vertical support bars 41, 51, 42 and 52.

In addition, the guide connector 34 disperses loads and moments due to the load, and the housings and moments transmitted to the vertical support bars 41, 51, 42 and 52 are transmitted to the support wheels 35 And is closely adhered to the vertical support bars 41, 51, 42, and 52 and dispersed. Particularly, the support wheels 35 and 38 support the first and second guide frames 31 and 32, thereby suppressing the bending moment formed in the first and second guide frames 31 and 32.

The guide connector 34 is formed by being bent in a 'C' shape in order to avoid interference with the vertical support bars 51 and 52.

8 is a perspective view of the lift device according to the second embodiment of the present invention, FIG. 9 is a front view of the lift module shown in FIG. 8, FIG. 10 is a right side view of FIG. 8, Fig.

As shown in the drawing, the lift device according to the present embodiment is further provided with a drive module 60 for moving the lift module up and down by its own power, unlike the first embodiment.

The driving module 60 includes a driving motor 61, a driving pinion 62 coupled to the driving motor 61 and a driven pinion 64 rotated by receiving a rotational force of the driving pinion 62, A chain 63 connected to the drive pinion 62 and the driven pinion 64 to transmit rotational force to the drive pinion 62 and the follower pinion 64 and a chain 63 fixed to the support module 20 and extended in the vertical direction, A rack gear 65 meshing with the rack gear 65 and a rack gear 65 meshing with the rack gear 65 via a resilient force to press the driven pinion 64 toward the rack gear 65 to maintain the meshing of the rack gear 65 and the driven pinion 64, (66).

The driving motor 61 is fixed to the lift module 110 and the driving pinion 62 can be connected to the driving motor 61 through a reduction gear or the like.

The driven pinion 64 is disposed below the drive pinion 62 in the present embodiment and the chain 63 connects the drive pinion 62 and the driven pinion 64.

Since the drive motor 61 and the driven pinion 64 are located at a distance from each other, the drive force of the drive motor 61 is transmitted indirectly through the drive pinion 62 and the chain 63, To the driven pinion 64. However, unlike the present embodiment, the driving motor 61 and the driven pinion 64 are directly coupled to transmit the driving force directly.

The rack gear 65 is formed on the driven pinion 64 so as to engage with the driven pinion 64 in a vertically long tooth shape. A rack gear fixing member 67 is provided to fix the rack gear 65 to the support module 20 and the rack gear fixing member 67 is fixed to the horizontal support bar 44.

A pinion guide 68 is further disposed so that the driven pinion 64 can be moved in the vertical direction while maintaining a state in which the driven pinion 64 is meshed with the rack gear 65, A guide plate 68a disposed on one side of the rack gear 65 and fixed to the driven pinion 64 and a guide roller 68b contacting the opposite surface of the tooth formed on the rack gear 65. [

Therefore, the driven pinion 64 and the guide roller 68b are brought into close contact with the one side and the other side of the rack gear 65 by the guide plate 68a, and through the driven pinion 64 and the rack gear 65, So that the engagement of the engagement portions can be maintained more effectively. In particular, the guide roller 68b prevents the driven pinion 64 from being separated from the rack gear 65 by a predetermined distance in the process of moving the driven pinion 64 up and down.

The coupling elastic member 66 is installed on the lift module 110 through an elastic force and urges the driven pinion 64 toward the rack gear 65 so that the driven pinion 64 is moved in the horizontal direction And is brought into close contact with the rack gear 65 side by the elastic force.

Reference numeral 70 denotes a power supply unit 70 for supplying power to the drive motor 61, which is a cable 71 and a drum 72.

Hereinafter, the operation of the driving module 60 will be described.

First, when the drive motor 61 is operated, the drive pinion 62, the chain 63 and the driven pinion 64 are rotated in order, and the driven pinion 64 is rotated to rotate the engaged rack gear 65 And thus can be moved upward or downward.

The coupling elastic member 66 and the pinion guide 68 are provided to minimize the clearance generated during the up and down movement of the driven pinion 64 and to maintain the engagement state of the driven pinion 64 and the rack gear 65 .

Meanwhile, the drive module 60 according to the present embodiment may be operated separately from the crane described in the first embodiment.

That is, the lift module 110 can be operated independently, regardless of the operation of the crane, so that the lift module 110 can be moved up and down.

Also, the lift module 110 can be moved up and down by operating only the crane without operating the drive module 60, and the crane and the drive module 60 can be simultaneously driven to move the lift module 110 It can also be activated.

The remaining configuration is similar to that of the first embodiment, and a detailed description thereof will be omitted.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is to be understood that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
