In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0036] like Figure 1 and Figure 3As shown, this embodiment provides a lifting device, which includes: a first lifting assembly 10, a second lifting assembly 20 and a third lifting assembly 30; wherein the first lifting assembly 10 includes a first pillar 11 and a driving member 12; the second lifting assembly 20 includes a second pillar 21; the third lifting assembly 30 includes a third pillar 31; the first pillar 11 is set at a supporting position, and the two ends of the second pillar 21 are respectively connected to the first pillar 11 and the third pillar 31 by transmission, and the end of the third pillar 31 away from the second pillar 21 can be connected to the transported object, and the driving member 12 can drive the second pillar 21 and the third pillar 31 to rise or fall along the Z axis at the same time.
[0037] The second support 21 and the third support 31 are driven to rise or fall along the Z axis at the same time by the driving member 12, which can not only meet the long-distance lifting and lowering requirements, but also after use, the second support 21 and the third support 31 can be retracted to the preset position by the driving member 12. It occupies a small space, has a compact structure, and is easy to transport and use. It is worth noting that in the present embodiment, the driving member 12 is a servo stepper motor, and the control accuracy of the servo stepper motor is high, so that the purpose of accurately controlling the lifting height can be achieved. In other embodiments, structures such as driving cylinders can also be used, as long as it can ensure accurate control of the distance of the second support 21 and the third support 31 rising and falling along the Z axis, and no other restrictions are made in the present embodiment.
[0038] In order to save space, Figure 1 , Figure 3 and Figure 4 As shown, the second pillar 21 is arranged on one side of the first pillar 11. This structure can not only ensure that the second pillar 21 can smoothly rise or fall along the Z-axis direction, but also enable the driving member 12 to drive the second pillar 21 to rise after use, so that the second pillar 21 and the first pillar 11 are stacked in the thickness direction, thereby further achieving the purpose of saving space.
[0039] In order to simplify the overall structure of the lifting device, Figure 3 As shown, a ball screw 111 is provided on one side of the first pillar 11 close to the second pillar 21, one end of the ball screw 111 is drivingly connected to the output end of the driving member 12, and a ball nut is provided on one side of the second pillar 21 close to the first pillar 11, and the ball nut is drivingly connected to the ball screw 111, so that the driving member 12 can drive the second pillar 21 to rise or fall along the Z axis. This arrangement can drive the ball screw 111 to move through the driving member 12, thereby indirectly driving the second pillar 21 to rise or fall along the Z axis, with a simple structure, easy installation and low cost.
[0040] To further ensure that the second support 21 moves up or down along the Z axis more smoothly, as shown in FIG. Figure 3As shown, at least two slide rails 112 are arranged at intervals along the X-axis direction on one side of the first pillar 11 close to the second pillar 21, and at least two slide rails 112 are arranged on both sides of the ball screw 111 along the X-axis direction. A slide groove is arranged on one side of the second pillar 21 close to the first pillar 11, and the slide groove is slidably connected with the slide rail 112. By setting the slide groove and the slide rail 112, it can not only ensure that the second pillar 21 can slide up and down smoothly along the Z-axis, but also will not deviate from the preset direction, and the use effect is good. It is worth noting that in this embodiment, there are two slide rails 112, and the two slide rails 112 are respectively arranged on both sides of the ball screw 111 along the X-axis direction. In other embodiments, different numbers of slide rails 112 can be set according to actual needs, as long as it can ensure that the second pillar 21 can slide up and down smoothly along the Z-axis, and no other restrictions are made in this embodiment.
[0041] like Figure 1 and Figure 3 As shown, the second support 21 is provided with an escape space 211 along the Z axis direction, and the third support 31 can rise or fall along the Z axis in the escape space 211. With this arrangement, after the lifting work is completed, the third support 31 can rise along the Z axis and be placed in the escape space 211 of the second support 21, thereby achieving the purpose of saving space.
[0042] The third support 31 can move synchronously with the second support 21, such as Figure 1 and Figure 3 As shown, a synchronous belt 22 and a synchronous wheel 23 are provided on both sides of the second pillar 21 along the X-axis direction, a synchronous clamp 32 is provided on one end of the third pillar 31 close to the second pillar 21, and the synchronous clamp 32 clamps the synchronous belt 22, and a clamp block 13 is fixedly provided on both sides of the first pillar 11 along the X-axis direction, and the clamp block 13 is used to clamp and drive the synchronous belt 22 to rise or fall, so that the synchronous belt 22 drives the third pillar 31 to rise or fall through the synchronous clamp 32. By fixing the clamping block 13 on both sides of the first pillar 11, when the second pillar 21 descends, it will generate relative movement with the clamping block 13, that is, the clamping block 13 drives the clamped synchronous belt 22 to move upward along the Z axis. Since the synchronous belt 22 is wound around the synchronous wheel 23, the synchronous belt 22 on the other side of the synchronous wheel 23 will move downward along the Z axis. The synchronous clamp 32 of the third pillar 31 is clamped on the synchronous belt 22 on this side. Therefore, the third pillar 31 will move downward along the Z axis driven by the synchronous belt 22, thereby realizing synchronous transmission of the third pillar 31 and the second pillar 21.
[0043] To facilitate the connection between the third support 31 and the object to be transported, Figure 1-Figure 4As shown, the third lifting assembly 30 also includes a connecting member 33, which is arranged at one end of the third pillar 31 away from the synchronous clamp 32. The connecting member 33 is provided with a plurality of connecting holes in the circumference, and the transported object can be connected through the plurality of connecting holes. It is worth noting that in this embodiment, a detachable connection is formed between the connecting member 33 and the clamp, and the transported object is clamped by the clamp. In other embodiments, structures such as claw clamps can also be connected through the connecting member 33, as long as the transportation of the transported object is convenient, and no other limitations are made in this embodiment.
[0044] like Figure 1-Figure 4 As shown, the first lifting assembly 10 further includes a support frame 14, the support frame 14 is at the supporting position, the first pillar 11 is connected to the support frame 14 on the side away from the second pillar 21, and the driving member 12 is arranged on the support frame 14. By providing the support frame 14, the connection of the first pillar 11 at the supporting position can be facilitated, and the stability of the lifting process can also be ensured.
[0045] like Figure 2 and Figure 4 As shown, the lifting device further includes a wiring assembly 40, and the wiring assembly 40 includes a drag chain 41, one end of the drag chain 41 is connected to the support frame 14, and the other end is connected to the second pillar 21. It is worth noting that since the second pillar 21 and the third pillar 31 need to move back and forth, by setting the drag chain 41, the required cables, wires and other components can be placed in the drag chain 41, so as to prevent the cables and wires from being entangled, worn, pulled off, scattered, etc., thereby avoiding affecting the normal lifting work, ensuring good use effect and high work efficiency.
[0046] like Figure 2 and Figure 4 As shown, the wiring assembly 40 further includes a first guide groove 42 and a second guide groove 43, wherein the first guide groove 42 is connected to the support frame 14 along the Z-axis direction, and the second guide groove 43 is connected to the second pillar 21 along the Z-axis direction, so that when the second pillar 21 rises or falls, the drag chain 41 can be respectively accommodated in the first guide groove 42 and the second guide groove 43. Through this arrangement, it can be ensured that the drag chain 41 can be exposed to the outside as little as possible during the rising or falling process, thereby ensuring safety in use.
[0047] Combine the following Figure 1 and Figure 3 The following describes the working process of the lifting device of this embodiment:
[0048] Before use, the lifting device should be Figure 1 As shown, at this time, the driving member 12 is turned on, and the driving member 12 can drive the second support 21 to descend along the Z axis through the ball screw 111, and drive the third support 31 to descend along the Z axis through the synchronous belt 22 and the synchronous wheel 23; Figure 3As shown, when it descends to the corresponding workstation, the transported object is connected to the connecting piece 33 of the third support 31, and the motor drives the second support 21 and the third support 31 to rise along the Z axis, so as to transport the transported object to the desired workstation. After use, the transported object is removed and the lifting device is restored to the position shown in FIG. Figure 1 Status shown.
[0049] In summary, the lifting device of this embodiment not only occupies a small space and has a compact structure, but can also accomplish lifting to a relatively large height.
