Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, a lifting device 100 includes a driver 110, a rotating member 120, a pulling member 130, and a limiting mechanism 140. The driver 110 is adapted to be mounted to a mounting plate 400 of a road wheel (not shown). The rotating member 120 is mounted on a first output shaft (not shown) of the driver 110 and can rotate around an axis of the first output shaft. The pulling member 130 is used to connect between the rotating member 120 and the roller 500 of the road wheel. The limiting mechanism 140 includes a limiting seat 141 and a control member 142. The control element 142 is movably disposed on the limiting seat 141. When the rotating member 120 rotates in the first direction, the control member 142 can be pushed open, and the pulling member 130 is driven to lift the roller 500 of the traveling wheel. When the rotation member 120 rotates in the second direction, the rotation member 120 abuts against the control member 142 and the roller 500 is maintained in a lifted state by the pulling member 130. The first direction is opposite to the second direction, and specifically, if the first direction is clockwise, the second direction is counterclockwise.

In the lifting device 100, the driver 110 drives the rotating member 120 to rotate, and drives the pulling member 130 to move, so that the roller 500 on the traveling wheel can be lifted relative to the mounting plate 400, and the mounting plate is lifted off the ground. In addition, during the lifting of the roller 500, the rotation member 120 rotates in the first direction, lifting up the control member 142 from the bottom up; when the pulling member 130 lifts the roller 500 to a certain position, the rotating member 120 is rotated along the second direction (i.e. the rotating member 120 is rotated in the reverse direction), and the rotating member 120 abuts against the control member 142 from top to bottom to limit the rotating member 120 to continue rotating along the second direction, so that the roller 500 is kept in a lifting state and prevented from falling back to the ground, and thus, the roller 500 is effectively prevented from generating a large sliding friction force with the ground when rotating, and manual pushing is greatly facilitated. Since the lifting device 100 has a power output of the driver 110, the power supply of the driver 110 may be additionally provided when lifting the roller 500, separately from the main power supply of the automated guided vehicle. Therefore, the lifting device 100 can automatically lift the roller 500 in a power-off state to facilitate manual pushing of the automated guided vehicle.

As shown in fig. 3 and 5, the first direction is a direction indicated by an S arrow and is clockwise, and the second direction is a direction indicated by a T arrow and is counterclockwise. When the rotating member 120 rotates in the first direction and pushes the control member 142 open, the control member 142 rotates in the second direction (counterclockwise direction).

As can be appreciated, during the rotation of the rotation member 120 in the first direction driven by the driver 110, the rotation member 120 contacts the control member 142 toward one side of the roller 500; the rotation is continued to drive the pulling member 130 to lift the roller 500 relative to the mounting plate 400. When the roller 500 is lifted to a certain height, the rotating member 120 is separated from the control member 142, and continues to rotate under the driving of the driver 110 until the roller stops rotating after reaching a preset height. At this point, the drive 110 may be powered down and stopped. Then, the roller 500 will pull the rotation member 120 to rotate in the second direction by its own weight. After rotating to a certain angle in the second direction, the rotating member 120 contacts a side of the control member 142 away from the roller 500, and at this time, the limiting seat 141 and the control member 142 limit the rotating member 120 to continue rotating in the second direction, i.e., limit the control member 142, the rotating member 120, the pulling member 130 and the roller 500, so that the roller 500 is kept in a lifted state.

It should be noted that "the control member 142 can be pushed open when the rotating member 120 rotates in the first direction" can be understood as follows: the rotating member 120 abuts against the control member 142 and continues to rotate along the first direction, so that the control member 142 is elastically separated from the limiting seat 141; alternatively, the rotating member 120 abuts against the control member 142 and continues to rotate in the first direction, so that the control member 142 rotates relative to the stopper seat 141, and the like.

In one embodiment, when the rotating member 120 separates the control member 142 from the constraining seat 141, the control member 142 should be located above the constraining seat 141, and an elastic connecting member 145 (such as a spring, etc.) should be disposed between the control member 142 and the constraining seat 141, so that the control member 142 can be elastically separated from the constraining seat 141 from a lower side (a side facing the roller 500) of the control member 142 when the rotating member 120 rotates along the first direction; when the rotating member 120 rotates in the second direction, the control member 142 can be pressed against the position-limiting seat 141 from the upper side surface (the side surface facing away from the roller 500) of the control member 142, so that the rotating member 120 is limited.

In one embodiment, referring to fig. 2, 4 and 6, the limiting mechanism 140 further includes a limiting member 143 disposed on the limiting base 141. The control member 142 is rotatably mounted on the limiting seat 141. When the rotating member 120 rotates in the second direction, the control member 142 can be in limit fit with the limiting member 143.

Therefore, the limiting member 143 limits the rotation member 120 from rotating in the second direction by limiting the control member 142 from rotating in the first direction, so as to limit the rotation member 120, the pulling member 130 and the roller 500, and thus the roller 500 is kept in the lifted state.

Further, as shown in fig. 2, 4 and 6, during the process of lifting the roller 500, the control member 142 can be rotated in the second direction by the rotation member 120. When the rotating member 120 is separated from the control member 142, the control member 142 is limited by the limiting member 143 after rotating in the first direction for a certain angle under the action of its own gravity, and cannot continue to rotate in the first direction, so that the rotation direction of the control member 142 is limited, and the rotating member 120 cannot rotate to the initial position in the second direction.

In the present embodiment, the control member 142 can rotate to the horizontal state along the first direction under the effect of its own weight. At this time, the rotation in the first direction cannot be continued under the restriction of the stopper 143.

Alternatively, the limiting member 143 may be mounted on the limiting seat 141 by, but not limited to, bolting, clamping, riveting, welding, bonding, pinning, etc. Of course, the two components can be integrally formed. Wherein the integral molding is injection molding, casting, and the like.

Specifically, in the present embodiment, the limiting member 143 is bolted to a side surface of the limiting seat 141 facing away from the roller 500, wherein the bolting point is located at two sides of the control member 142. In this way, it is possible to secure a sufficient space for the control member 142 to rotate in the second direction and to restrict the control member 142 from rotating in the first direction.

In one embodiment, referring to fig. 2, the limiting mechanism 140 further comprises a supporting member 144. One end of the supporting member 144 is used for connecting to the steering mechanism 200, and the other end is connected to the limiting seat 141.

It will be appreciated that the support 144 is positioned between the mounting plate 400 and the spacing block 141 to improve the stability of the spacing block 141.

Alternatively, the number of the supporting members 144 may be one, two or more. Specifically, in the present embodiment, the number of the supporting members 144 is two, and the supporting members are located at both sides of the control member 142.

In one embodiment, referring to fig. 2, 4 and 6, the rotating member 120 further includes a connecting member 145. The rotating member 120 is provided with through holes 121 and coupling holes 122 at intervals. The first output shaft of the driver 110 is disposed through the through hole 121 and is used to drive the rotating member 120 to rotate around the central axis of the through hole 121. The connecting member 145 is inserted into the connecting hole 122 and connected to the pulling member 130.

Therefore, when the driver 110 drives the rotating member 120 to rotate, one end of the pulling member 130 fixed to the connecting hole 122 also rotates, so that the roller 500 connected to the other end of the pulling member 130 is lifted off the ground or returned to the ground.

It is understood that the rotation plane of the rotation member 120 is not parallel to the horizontal plane. Specifically, the rotation plane of the rotation member 120 is perpendicular to the horizontal plane. Compared with other cases, the rotation plane of the rotation member 120 is perpendicular to the horizontal plane, so that the roller 500 can be driven to lift the roller by the maximum distance when the rotation member 120 rotates a certain angle.

It can be further understood that the larger the distance between the connecting hole 122 and the through hole 121 is, the larger the distance that the pulling member 130 lifts the roller 500 when the rotating member 120 rotates.

In one embodiment, referring to fig. 2, the rotating member 120 further includes a positioning member (not shown). The rotating member 120 is provided with a positioning hole 123. The positioning hole 123 communicates with the through-hole 121. The positioning element is inserted into the positioning hole 123, and penetrates through the through hole 121, and is connected to the first output shaft of the driver 110 inserted into the through hole 121. Therefore, the positioning element is disposed through the positioning hole 123 communicating with the through hole 121, and can fix the rotating element 120 and the first output shaft of the driver 110, so as to prevent the rotating element 120 from falling off from the first output shaft, and further ensure that the rotating element 120 can drive the pulling element 130 and the roller 500 to move during the rotation process.

Further, in the present embodiment, the positioning hole 123 is opened at an end of the rotating member 120 away from the control member 142, and is communicated with the through hole 121. Therefore, the positioning member can fix the rotation member 120 and the driver 110 in a direction perpendicular to the first output shaft, thereby better preventing the rotation member 120 from falling off the driver 110.

In one embodiment, referring to fig. 2, a bracket 150 is further included. The bracket 150 includes a bottom plate 151 and a side plate 152 connected to the bottom plate 151. The base plate 151 is coupled to the mounting plate 400. The side plates 152 are used to connect the driver 110.

Therefore, the driver 110 is mounted on the side plate 152 of the bracket 150, and the bottom plate 151 of the bracket 150 is connected to the mounting plate 400, so that the driver 110 is stably connected to the mounting plate 400, and the stability of the driver 110 driving the rotating member 120 to rotate so as to drive the pulling member 130 and the roller 500 to lift is improved.

In one embodiment, referring to fig. 2, a recess (not shown) is formed at an end of the retainer 141 facing the rotating member 120. The control member 142 is rotatably coupled to an inner wall of the recess and is rotatable in a second direction within the recess.

Therefore, the control member 142 directly rotates and is disposed in the recess of the limiting seat 141, which not only saves the manufacturing cost, but also saves the installation space, thereby improving the portability of the lifting device 100.

It can be understood that when the control element 142 is directly rotated to be disposed in the recess of the position-limiting base 141, the position-limiting element 143 is located above the control element 142, so that the control element 142 cannot continue to rotate in the first direction when it is in a horizontal state.

In one embodiment, referring to fig. 2, the extending direction of the first output shaft and the extending direction of the control member 142 form an included angle.

Alternatively, the included angle may be any angle greater than 0 ° and less than 180 °.

Specifically, in the present embodiment, the axial direction of the first output shaft is perpendicular (at an angle of 90 °) to the extending direction of the control member 142.

In one embodiment, please refer to fig. 2, further comprising a lifting member 160. The lifting member 160 is used to connect the trolley 500 of the road wheel. The end of the pulling member 130 away from the rotating member 120 is connected to the lifting member 160.

Therefore, the pulling member 130 pulls the lifting member 160 to move under the driving of the driver 110 and the rotating member 120, so that the roller 500 can be lifted relative to the mounting plate 400 and lifted off the ground.

It can be understood that the lifting member 160 is fixedly connected to the roller 500, and one end of the pulling member 130 is connected to the rotating member 120, and the other end is connected to the lifting member 160, so as to drive the roller 500 to lift. Wherein the lifting member 160 can be, but is not limited to, a beam, a steel bar, an aluminum bar, etc.

Specifically, in the present embodiment, the pulling member 130 is a steel cable, and the lifting member 160 is a beam.

In an embodiment, the lifting device 100 further includes a guide member (not shown) disposed between the rotating member 120 and the roller 500, the pulling member 130 is wound on the guide member, and the pulling member 130 passes through the guide member 1 to change the connection position between the pulling member 130 and the lifting member 160, so that the lifting member 160 is more uniformly stressed during the lifting process. The number of the guide members may be plural according to actual requirements, and is not limited herein.

It should be noted that, referring to fig. 1, fig. 4 and fig. 6, the working principle of the lifting device 100 is as follows:

starting the driver 110, wherein the driver 110 rotates the first output shaft in the first direction and drives the rotating member 120 to rotate in the first direction, so as to drive the pulling member 130 fixedly connected to the rotating member 120 to rotate, and thus the pulling member 130 pulls the lifting member 160 to lift the roller 500;

the rotating member 120 continues to rotate in the first direction, contacts the control member 142, and pushes the control member 142 to rotate in the second direction;

the rotating member 120 continues to rotate in the first direction and is separated from the control member 142, the rotating member 120 continues to rotate in the first direction to a preset position, and at this time, the roller 500 is lifted to a high point;

the driver 110 is powered off, the rotating member 120 rotates along the second direction under the action of the gravity of the roller 500 until contacting the control member 142, the control member 142 cannot rotate under the limit of the limit member 143, so as to limit the rotation of the rotating member 120 and the falling of the roller 500, and at this time, the roller 500 is in a lifting state;

the driver 110 is activated, and the driver 110 drives the rotation member 120 to rotate in the first direction until the roller 500 falls back to the ground, and the driver 110 stops working, and the roller 500 is at the low point.

It should be noted that the high point is a position where the lifting device 100 lifts the roller 500 higher than the original position, and the low point is the original position of the roller 500.
