FIG. 2 is a plan view illustrating a wheel suspension apparatus according to an embodiment of the present invention. Sectional view showing a coupling structure of a moving device and a moving wheel fingers in a wheel suspension device according to an embodiment of the present invention.

1 to 3, a wheel suspension apparatus according to an embodiment of the present invention includes a support 110, a fixing member 120, a fixed wheel fingers 130, a moving device 140, a movable wheel fingers 150 And a driving unit 160. [

The support 110 includes a support rod 111 and legs 113. The support rod 111 extends upwardly from the fixing member 120 in an upward direction. The support rod 111 is formed in the shape of a circular or polygonal pipe. The legs 113 extend downward from the support rods 111 to support the support rods 111. The leg 113 supports the support bar 111 so that the support bar 111 is erected in an inclined state even if the operator does not hold the support bar 111. [ Therefore, the operator can hold the support rod 111 without bending the waist.

The support rod 111 and the legs 113 are connected by a reinforcing member 115. Both sides of the reinforcing member 115 are connected to the support rod 111 and the leg 113 so that the support rod 111 and the leg 113 can be prevented from being opened or deformed.

The fixing member 120 is fixed to the support 110. At this time, the fixing member 120 is connected to the lower end of the support rod 111. The fixing member 120 is formed in the shape of a circular or polygonal pipe. Both sides of the fixing member 120 are bent toward the opposite side of the legs 113. [ On the other side of the fixing member 120, a fixing bar 123 (see FIG. 3) extends to the opposite side of the leg 113.

The fixed wheel fingers 130 are fixed to one side of the fixing member 120. The fixed wheel support 130 includes a wheel support body 131 for holding the wheel 10 and a fixing portion 133 extending from the wheel support body 131 and fixed to the fixing member 120. The fixed wheel fingers 130 are formed so as to be lowered toward both sides from the central portion. The fixing portion 133 is formed in a bar shape.

The moving device 140 is movably coupled to the other side of the fixing member 120. At this time, the moving device 140 is slidably coupled to the fixing bar 123 of the fixing member 120 so as to be moved. The moving device 140 includes a moving rod 141 and an elastic member 143.

The movable rod 141 is movably coupled to the other side of the fixed member 120 and is coupled to the movable wheel fingers 150 at one side. At this time, the moving rod 141 is movably coupled to the fixed bar 123. The elastic member 143 is coupled to the moving rod 141 to apply an elastic force to the moving rod 141 so that the moving rod 141 is restored. The elastic member 143 exerts an elastic force in a direction in which the moving rod 141 moves away from the fixed bar 123. The elastic member 143 may be a coil spring in which the moving rod 141 is inserted.

The moving device 140 further includes an adjusting screw 145 screwed to the other side of the moving rod 141 to adjust a moving range of the moving rod 141. At this time, on the other side of the moving rod 141, a thread 141a is formed so that the adjusting screw portion 145 is screwed. As the adjustment screw portion 145 is rotated to one side, the moving rod 141 is moved to the fixed wheelbase 130 side. At this time, the distance between the fixed wheel fingers 130 and the movable wheel fingers 150 becomes close to each other. Further, as the adjusting screw portion 145 is rotated to the other side, the moving rod 141 is moved to the opposite side of the fixed wheel fingers 130. At this time, the distance between the fixed wheel fingers 130 and the moving wheel fingers 150 is large.

A plurality of moving rods (141) are provided on the other side of the fixing member (120). A plurality of moving rods 141 are installed, so that the moving wheel fingers 150 can be stably supported. Therefore, the movable wheel fingers 150 can be stably moved with little fluctuation.

The moving device 140 further includes a bush 147 installed in the fixing member 120 and into which the moving rod 141 is slidably inserted. The bush 147 guides the moving rod 141 to move in a slidable manner with little fluctuation.

The movable wheel fingers 150 are coupled to a fixed bar 123 formed on the other side of the fixed member 120. [ The moving wheel guide 150 includes a wheel guide body 151 for holding the wheel 10 and a moving part 153 extending from the wheel guide body 151 and coupled to the moving rod 141 of the moving device 140 . The moving wheel fingers 150 are formed so as to be lowered toward both sides from the central portion. The moving part 153 is formed in a rod shape.

The driving device 160 is installed on the support 110 and is connected to the moving device 140 so that the moving wheel 150 can be moved as the moving device 140 is moved.

The driving device 160 includes a wire 161 and a driving lever 163. One side of the wire 161 penetrates through the fixing bar 123 of the fixing member 120 and is connected to the moving part 153 of the moving wheel fingers 150. The other side of the wire 161 is connected to the drive lever 163. The drive lever 163 is rotatably mounted on the support rod 111 of the support table 110 to move the wire 161. The wire 161 is surrounded by a cloth 162.

When the drive lever 163 is pressed, the moving wheel fingers 150 are moved toward the fixed bar 123 as the wire 161 is pulled. When the drive lever 163 is released from pressure, the moving wheel fingers 150 are moved to the opposite side of the fixed bar 123 as the wire 161 is moved to the home position. Since the moving wheel fingers 150 are moved by the operation of the driving device 160, the operator can hold the wheels 10 in a state away from the wheel 10. [ Therefore, it is possible to prevent the worker's hand or the like from being injured by the wheel 10. [

The operation of the wheel suspension apparatus according to one embodiment of the present invention constructed as described above will be described.

FIG. 5 is a cross- 6 is a state view showing a state in which the moving wheel fingers are moved toward the fixed wheel fingers in order to hold the wheels in the wheel suspension apparatus according to the embodiment of the present invention.

4 to 6, as the driving lever 163 is pressed, the wire 161 is pulled toward the driving lever 163 side. When the wire 161 is pulled toward the drive lever 163, the moving wheel fingers 150 are moved to the fixed wheel fingers 130 side. The elastic member 143 is retracted and the movable rod 141 is moved to the fixed wheel fingers 130 side while sliding on the bush 147. As the movable wheel fingers 150 are moved toward the fixed wheel fingers 130, After the fixed wheel fingers 130 and the moving wheel fingers 150 are positioned between the wheels 10, the fixed wheel fingers 130 are fixed to the fixed wheel fingers 130 so that one wheel 10 (the lower wheel in Fig. 6) (130). At this time, the movable wheel fingers 150 are separated from the other wheel 10 (the upper wheel in Fig. 6).

FIG. 2 is a plan view showing a wheel suspension apparatus according to an embodiment of the present invention, FIG. 3 is a cross-sectional view showing a coupling structure of a moving apparatus and a moving wheel fingers in a wheel suspension apparatus according to an embodiment of the present invention, 7 is a state view showing a state in which the moving wheel fingers are moved to the opposite side of the fixed wheel fingers in the wheel lifting device according to the embodiment of the present invention, and the wheels are stuck.

Referring to Figs. 2, 3 and 7, the contracted elastic members 143 exert an elastic force to urge the moving wheel fingers 150 to the opposite side of the fixed wheel fingers 130. The movable wheel fingers 150 are moved to the opposite side of the fixed wheel fingers 130 by the elastic force of the elastic members 143. As a result, When the movable wheel fingers 150 are moved to the opposite side of the fixed wheel fingers 130, the elastic members 143 are extended. At this time, the moving rod 141 slides on the bush 147 and is moved to the opposite side of the fixed wheel fingers 130. And the other wheel 10 (the upper wheel in Fig. 6) is lifted as the moving wheel fingers 150 are moved to the opposite side of the fixed wheel fingers 130. [

The fixed wheel fingers 130 and the moving wheel fingers 150 are separated from the wheel 10 when the support rod 110 is pulled after the drive lever 163 is pressed.

The distance between the moving wheel fingers 150 and the fixed wheel fingers 130 is adjusted as the driving lever 163 is operated so that the moving wheel fingers 150 and the fixed wheel fingers 130 can be easily rotated (10). In addition, since the operator can hold the wheel 10 without holding the moving wheel fingers 150 and the fixed wheel fingers 130 by hand, it is possible to prevent the operator from being injured by the wheel 10. [
