Description

Flexible supporting device

Technical Field

The utility model relates to a lift support technical field, more specifically relates to a flexible strutting arrangement.

Background

In the technical field of lifting systems, in order to provide a stable lifting moment and a stable supporting plane for a lifting device, a multi-point supporting technology is adopted. In the conventional multi-point supporting technology, a multi-point layout of a plurality of synchronous motors is a common technology, and the synchronous motors provide the same displacement under the driving of electric power, so that a supporting plane is stressed at a plurality of points simultaneously, thereby providing a lifting moment and maintaining the supporting capability of the supporting plane. This kind of technical scheme need set up a plurality of synchronous machine for system cost is higher, and on the other hand, the volume that each motor occupies is also great, makes entire system's occupation space more. In addition, the failure of any synchronous motor can cause the whole system to stop running, so that the reliability of the technical scheme is low. In another common multi-point supporting technology, a bevel gear is adopted to transmit torque in the vertical direction, and support of multiple points is expanded through cascade transmission, but the bevel gear can only transmit the torque in the vertical direction, so that the device is not flexible in design. The bevel gear carries out torque transmission through a rigid transmission rod, and the occupied volume is large.

In view of this, the utility model provides a flexible supporting device alleviates the technical problem that current multiple spot support technique exists.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and the described embodiments are some, but not all embodiments of the present invention.

The first embodiment is as follows:

fig. 1 is a schematic structural view of a flexible supporting device according to a first embodiment of the present invention, as shown in fig. 1, the flexible supporting device includes: fixed pulley 1, connecting wire 2, slider 3, supporting component 4 and slide rail 5, fixed a plurality of fixed pulleys 1 at the both ends of slide rail 5, fixed a fixed pulley in the one end of slide rail 5, fixed two slightly less fixed pulleys 1 of radius at the other end. The two slide rails 5 are connected by a connecting line 2, as shown in fig. 1, the connecting line 2 is wound around a fixed pulley 1 with a slightly smaller radius and is connected in a closed loop by a sliding block 3, so that the connecting line 2 moves along the wound fixed pulley 1 during the sliding process of the sliding block 3. The two sliding rails 5 are respectively provided with a sliding block 3, and the two sliding blocks 3 have the same moving direction on the connecting line 2 and are positioned on the same horizontal line, so that the two sliding blocks 3 slide along the same direction at the same distance in the sliding process. The two sliding blocks 3 are arranged in the grooves of the sliding rail 5, so that the sliding blocks 3 only move linearly along the connecting line 2; on both slides 3 a support assembly 4 is provided.

It should be noted that the movement direction of the connecting line 2 changes every time the connecting line passes through one fixed pulley, as shown in fig. 1, the movement direction changes by 90 degrees or 180 degrees after the connecting line 2 passes around the fixed pulley 1, so that the movement direction of the connecting line 2 remains unchanged after passing around a plurality of fixed pulleys 1. According to the transmission principle of the fixed pulley, after the connection 2 passes through the fixed pulley 1, the moving distances of all points on the connection 2 are the same. Therefore, one sliding block 3 can be arranged on each of the two sliding rails 5, so that the two sliding blocks 3 move in the same direction on the connecting line 2 and are in the same horizontal line. When a force in the direction of the connecting line 2 is applied to one of the sliders 3, the other slider also slides in the same direction and distance due to the transmission. In engineering practice, a motor can be arranged at the position of one sliding block 3 to drive two sliding blocks 3 which are not on the same sliding rail 5 to move simultaneously. On the other hand, set up supporting component 4 on two sliders 3, when supporting component 4 received pressure, can share two sliders 3 in, two sliders 3 are the same because motion and atress direction, consequently can transmit pressure to connecting wire 2 on to become the pulling force of connecting wire 2, because connecting wire 2 has walked around a plurality of fixed pulleys 1 and has shared the pulling force to a plurality of fixed pulleys 1, consequently reached static equilibrium, played the supporting role to supporting component 4 and its load. Therefore, the whole flexible supporting device can be driven by a certain slide block 3 to enable the supporting component 4 to move up and down, and can also play a supporting role in a static state.

In addition, since the connecting wire 2 is a flexible rope, if the moving direction of the slider 3 is not limited, the slider 3 will shake on the slide rail 5, and thus the slider 3 is mounted in the groove of the slide rail 5.

As shown in fig. 2, the connecting line 2 is fixed by the sliding block 3 through a bolt, so that the position of the sliding block 3 on the connecting line 2 can be adjusted, and the technical effect of enabling more than two sliding blocks 3 to be on the same horizontal line is achieved. In an alternative embodiment, the connection line 2 can thus be connected in a closed loop by means of the slider 3 using more than two lines, for the purpose of easy installation. As shown in fig. 3, the slider 3 can also fix the connecting wire 2 by injection molding.

As shown in fig. 4, the present embodiment further provides another flexible supporting device, and due to the flexible characteristic of the connecting line, the supporting device can be expanded to another plane, so that on one hand, the technical effect of jointly supporting multiple dimensions is achieved, and on the other hand, the lifting motion of the sliding block 3 is also transmitted to the positions of multiple different planes. Fig. 5 is a partial enlarged view of the schematic structural diagram of fig. 4, illustrating the installation position of the fixed pulley 1 at one end of the sliding rail 5, and it can be known from fig. 5 that the installation direction of the fixed pulley 1 can change the direction of the connection 2, thereby achieving the purpose of expanding different planes. Since the mounting direction of the fixed pulley 1 can be changed, the transmission direction of the connecting line 2 can also be flexibly set.

Example two:

the embodiment of the utility model provides a modular flexible supporting device is still provided, fig. 6 is a flexible supporting device schematic structure of this embodiment, and fig. 7 is another flexible supporting device schematic structure of this embodiment. As shown in fig. 6 and 7, two or more flexible supporting devices according to the first embodiment of the present invention are combined to form a combined flexible supporting device, and the combination includes two or more flexible supporting devices connected through a sliding block 3.

In an alternative embodiment, the connection of the slides 3 of two or more flexible support means comprises a fixed connection using an L-shaped member 6. The single flexible supporting device is easy to debug and install, different flexible supporting devices are connected through the L-shaped component 6, and the technical effects of multi-dimensional transmission and supporting can be achieved.
